下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。

如图1至图5所示，本实施例提供安全带锁扣测力试验设备，该安全带锁扣测力试验设备包括试验台机架1、锁扣安装装置2、负载施加装置3以及测力装置4；锁扣安装装置2设置于试验台机架1上，锁扣固定安装于锁扣安装装置2上；负载施加装置3设置于锁扣安装装置2的一侧，负载施加装置3包括第一驱动组件和拉力件，拉力件的一端与第一驱动组件的输出端连接，拉力件的另一端与锁舌100连接，第一驱动组件通过拉力件对锁舌100施加远离锁扣的负载力；测力装置4活动设置于锁扣安装装置2的一侧，测力装置4包括第二驱动组件、承载座组件以及负荷传感器41，承载座组件设置于第二驱动组件的输出端，负荷传感器41安装于承载座组件上，第二驱动组件用于驱动承载座组件靠近或远离锁扣安装装置2，以使承载座组件压向锁扣上的开启按钮或者承载座组件将锁舌100插入锁扣中，负荷传感器41用于检测锁舌100脱离于锁扣的开启力以及锁舌100插入锁扣的插入力。

具体的，当需要检测锁舌100脱离于锁扣的开启力时，先将锁舌100和锁扣安装于锁扣安装装置2上，此时锁舌100插设在锁扣中，负载施加装置3的拉力件选择性与锁舌100连接，第一驱动组件通过拉力件对锁舌100施加预设的负载力，模拟安全带在实际操作状态下对锁舌100的拉力，提高检测的准确性，第一驱动组件通过拉力件对锁舌100施加预设的负载力之后，锁舌100还未脱离于锁扣，此时，第二驱动组件驱动承载座组件逐渐靠近锁扣安装装置2并压向锁扣上的开启按钮，直至锁舌100从锁扣中弹出，负荷传感器41自动测出锁舌100从锁扣弹出瞬间承载座组件对开启按钮施加的压力，该压力为锁舌100在锁扣上的开启力；当需要检测锁舌100插入锁扣的插入力时，先将锁扣安装于锁扣安装装置2上，以及将锁舌100安装于承载座组件上，负载施加装置3的拉力件选择性与锁舌100连接，第一驱动组件通过拉力件对锁舌100施加预设的负载力，模拟安全带在实际操作状态下对锁舌100的拉力，提高检测的准确性，此时，第二驱动组件驱动承载座组件逐渐靠近锁扣安装装置2，安装于承载座组件上的锁舌100插入安装于锁扣安装装置2上的锁扣，负荷传感器41自动测出锁舌100插入锁扣瞬间承载座组件对锁舌100施加的插入力；采用本实施例的安全带锁扣测力试验设备能够分别检测锁舌100在锁扣上的开启力和插入力，减少检测设备的数量，降低检测成本。

在本实施例中，负载施加装置3的拉力件选择性与锁舌100连接，是指锁舌100在锁扣上的开启力检测和插入力检测均具有加载和不加载两种试验情况，当锁舌100在锁扣上的开启力检测和插入力检测均需要在加载的情况下进行试验时，第一驱动组件通过拉力件对锁舌100施加拉力，当锁舌100在锁扣上的开启力检测和插入力检测均不需要在加载的情况下进行试验时，第一驱动组件不施加拉力。

可选的，负载施加装置3设置于锁扣安装装置2沿X轴方向的一侧，锁扣安装装置2包括承载台21和第三安装板22，承载台21固定安装于试验台机架1上，第三安装板22沿X轴方向活动安装于承载台21上，锁扣固定安装于第三安装板22上。

具体的，当需要检测锁舌100脱离于锁扣的开启力时，将第三安装板22沿X轴方向移动至承载台21靠近负载施加装置3的一侧，当需要检测锁舌100插入锁扣的插入力时，将第三安装板22沿X轴方向移动至承载台21远离负载施加装置3的一侧，将第三安装板22安装在承载台21不同的位置，对应锁舌100的开启力和插入力的测试，能够提高检测的准确性，例如，由于锁扣是固定安装于第三安装板22上，而锁扣的开启按钮的移动路径短，即承载座组件压向开启按钮，以检测锁舌100的开启力时，开启按钮只移动很短的距离，锁舌100就能够从锁扣中弹出，而在检测锁舌100的插入力时，锁舌100的移动距离相对较长才能够完全插入锁扣中，因此需要将第三安装板22安装在承载台21远离负载施加装置3的一侧，从而提高检测的准确性。

可选的，锁扣安装装置2还包括前挡板23、后挡板24、压板25以及定位螺钉26，第三安装板22沿X轴方向开设有定位槽，定位螺钉26穿过定位槽并将第三安装板22固定于承载台21上，前挡板23和后挡板24沿X轴方向前后间隔设置于第三安装板22上，压板25设置于前挡板23上，压板25将锁扣压抵于第三安装板22上，后挡板24用于限定锁扣沿X轴方向的移动。

可选的，试验台机架1上设置有方向调整装置5，方向调整装置5包括第四驱动组件，负载施加装置3连接于第四驱动组件的输出端，第四驱动组件用于驱动负载施加装置3沿Y轴方向移动。

具体的，在实际情况中，安全带对锁舌100施加的拉力是不定向的，因此本实施例通过方向调整装置5带动负载施加装置3沿Y轴方向移动，能够模拟安全带在不同方向对锁舌100施加拉力，从而提高检测的准确性。

可选的，负载施加装置3还包括第一滑台31、转盘32、安装支架33以及滑轮34，第一滑台31与第四驱动组件的输出端连接，第四驱动组件用于驱动第一滑台31沿Y轴方向移动，转盘32绕Z轴方向转动安装于第一滑台31上，安装支架33安装于转盘32上，滑轮34绕Y轴方向转动安装于安装支架33上，第一驱动组件安装于第一滑台31，拉力件为织带35，织带35绕过滑轮34。

具体的，方向调整装置5带动负载施加装置3沿Y轴方向移动之后，拉力件偏离于X轴方向，因此，为了保证力的传递的有效性和准确性，本实施例的拉力件采用织带35，织带35能够绕过滑轮34，滑轮34改变力的传递的方向，且滑轮34能够跟随安装支架33在转盘32上饶Z轴方向转动，保证织带35的延伸方向始终能够垂直于滑轮34的中心轴线方向，保证力的传递的有效性和准确性。

可选的，第一驱动组件包括气缸36和砝码37，织带35绕过滑轮34的一端与砝码37连接，气缸36用于提升滑轮34或顶升砝码37。

在一些实施例中，气缸36安装于承载支架38上，砝码37位于气缸36的上方，当需要对锁舌100加载时，气缸36的输出端缩回而脱离于砝码37，砝码37的重力通过织带35传递至锁舌100，当不需要对锁舌100加载时，气缸36的输出端伸出而顶升砝码37，砝码37的重力施加于气缸36上，此时锁舌100不受砝码37的重力影响；在另外的一些实施例中，气缸36安装于安装支架33上，可选的，连接板39设置于气缸36的输出端，转轴310安装于连接板39上，滑轮34绕水平线转动套设于转轴310的外周，当需要对锁舌100加载时，气缸36提升连接板39、转轴310以及滑轮34，使得砝码37脱离于承载支架38，砝码37的重力通过织带35传递至锁舌100，当不需要对锁舌100加载时，气缸36下放滑轮34，使得砝码37承载于承载支架38上，此时锁舌100不受砝码37的重力影响。砝码37的重量可根据实际需要进行设置，例如200N或者300N，在需要对锁舌100施加不同的负载力时，也能够通过更换不同重量的砝码37实现。

可选的，承载支架38上设置有胶垫，胶垫用于弹性支撑气缸36或者砝码37。

可选的，气缸36的输出端的行程可根据实际需要进行设置，例如80毫米或者120毫米。

具体的，当需要检测锁舌100脱离于锁扣的开启力时，压头44压向锁扣的开启按钮，负荷传感器41能够测出压头44的压力，锁舌100从锁扣中弹出瞬间压头44的压力即为锁舌100的开启力；当需要检测锁舌100插入锁扣的插入力时，将锁舌100安装于第二安装板43上，第二安装板43带动锁舌100插入锁扣中，第二安装板43的受力通过压头44传递至负荷传感器41，锁舌100插入锁扣瞬间的压力即为锁舌100的插入力。

本实施例所使用的负荷传感器41的量程小且灵敏度高，频繁安装调整很容易造成检测精度下降，甚至过早损坏，为解决该问题，在本实施例中，压头44设置在负荷传感器41面向锁扣的一侧，无论是测锁舌100的插入力还是开启力，都不需要将负荷传感器41从第一安装板42上拆下，保证检测精度，避免负荷传感器41过早损坏，保证其使用寿命。

可选的，承载座组件还包括第二滑台49，第二滑台49安装于第二滑轨滑块组件上并与第二丝杆48螺纹连接，导向架46固定安装于第二滑台49上。

The following in conjunction with the accompanying drawings and further illustrate the technical solution of the present invention by a specific embodiment.

As shown in FIGS. 1 to 5, the present embodiment provides a seat belt lock force test device, the seat belt lock force test equipment includes a test bench frame 1, a lock mounting device 2, a load application device 3, and a force measuring device 4; The lock mounting device 2 is installed on the test bench frame 1, and the lock is fixed and installed on the lock mounting device 2; The load application device 3 is provided on one side of the lock mounting device 2, the load application device 3 includes a first drive assembly and a tensile member, one end of the tensile part is connected with the output end of the first drive assembly, the other end of the tensile part is connected with the deadbolt 100, and the first drive assembly applies a load force away from the lock tongue 100 through the tensile member; The force measuring device 4 is actively disposed on one side of the lock mounting device 2, the force measuring device 4 includes a second drive assembly, a load bearing seat assembly and a load sensor 41, the load base assembly is disposed at the output end of the second drive assembly, the load sensor 41 is installed on the load base assembly, the second drive assembly is used to drive the load carrier assembly close to or away from the lock mounting device 2, so that the load bearing seat assembly presses against the open button on the lock or the carrier seat assembly inserts the lock tongue 100 into the lock, Load sensor 41 is used to detect the opening force of the deadbolt 100 disengaging from the lock and the insertion force of the deadbolt 100 into the latch.

Specifically, when it is necessary to detect the opening force of the deadbolt 100 out of the lock, the deadbolt 100 and the lock are first installed on the locking installation device 2, at this time the deadbolt 100 is inserted in the lock, the tension member of the load application device 3 is selectively connected with the deadbolt 100, the first drive assembly applies a preset load force to the deadbolt 100 through the tensile part, simulates the tension of the safety belt on the deadbolt 100 in the actual operating state, and improves the accuracy of detection. After the first drive assembly applies a preset load force to the deadbolt 100 through the tension part, the deadbolt 100 has not yet detached from the lock, at this time, the second drive assembly drives the bearing seat assembly gradually approaching the locking mounting device 2 and pressing the opening button on the lock, until the deadbolt 100 pops out of the lock, the load sensor 41 automatically detects the pressure exerted by the deadbolt 100 from the lock popping out of the instant bearing seat assembly on the opening button, the pressure is the opening force of the deadbolt 100 on the lock; When it is necessary to detect the insertion force of the deadbolt 100 into the lock, the lock is first installed on the lock mounting device 2, and the deadbolt 100 is installed on the bearing seat assembly, the tension member of the load application device 3 is selectively connected with the lock tongue 100, the first drive assembly applies a preset load force to the lock tongue 100 through the tension piece, simulates the tension of the seat belt on the lock tongue 100 in the actual operating state, and improves the accuracy of detection, at this time, the second drive component drives the bearing seat assembly gradually approaching the lock installation device 2, The deadbolt 100 installed on the bearing seat assembly is inserted into the lock mounted on the lock mounting device 2, and the load sensor 41 automatically detects the insertion force exerted on the deadbolt 100 by the deadbolt 100 when the socket assembly is inserted instantly; The seat belt lock force test equipment using the present embodiment can separately detect the opening force and insertion force of the lock tongue 100 on the lock, reducing the number of testing equipment and reducing the testing cost.

In the present embodiment, the tensile force member of the load application device 3 is selectively connected with the deadbolt 100, which means that the opening force detection and insertion force detection of the deadbolt 100 on the lock have two test situations of loading and not loading, when the opening force detection and insertion force detection of the deadbolt 100 on the lock need to be tested under loading, the first drive assembly applies a tensile force to the deadbolt 100 through the tensile member, When the opening force test and insertion force detection of the deadbolt 100 on the lock do not need to be tested under loading, the first drive assembly does not apply a tensile force.

Optionally, the load application device 3 is disposed on one side of the lock mounting device 2 along the X-axis direction, the locking mounting device 2 includes a bearing table 21 and a third mounting plate 22, the bearing table 21 is fixed mounted on the test bench frame 1, the third mounting plate 22 is actively installed on the bearing table 21 in the X-axis direction, and the lock is fixed and installed on the third mounting plate 22.

Specifically, when it is necessary to detect the opening force of the deadbolt 100 detached from the lock, the third mounting plate 22 is moved in the direction of the X axis to the side of the bearing table 21 close to the load application device 3, when it is necessary to detect the insertion force of the lock tongue 100 into the lock, the third mounting plate 22 is moved in the X-axis direction to the side of the bearing table 21 away from the load application device 3, the third mounting plate 22 is installed in different positions of the bearing table 21, corresponding to the opening force and insertion force test of the deadbolt 100, which can improve the accuracy of detection, For example, since the lock is fixed on the third mounting plate 22, and the opening button of the lock has a short moving path, that is, the bearing seat assembly presses the opening button to detect the opening force of the deadbolt 100, the opening button only moves a short distance, the deadbolt 100 can be ejected from the lock, and when detecting the insertion force of the deadbolt 100, the moving distance of the deadbolt 100 is relatively long to be fully inserted into the lock, so the third mounting plate 22 needs to be installed on the side of the load-bearing table 21 away from the load application device 3, This improves the accuracy of detection.

Optionally, the locking mounting device 2 further comprises a front bezel 23, a tailgate 24, a pressure plate 25 and a positioning screw 26, a third mounting plate 22 is provided with a positioning groove along the X axis, the positioning screw 26 passes through the positioning groove and fixes the third mounting plate 22 to the bearing table 21, the front bezel 23 and the tailgate 24 are disposed on the third mounting plate 22 at the front and rear intervals in the X-axis direction, the pressure plate 25 is disposed on the front bezel 23, and the pressure plate 25 presses the lock against the third mounting plate 22, The tailgate 24 is used to limit the movement of the latch along the X-axis direction.

Specifically, when it is necessary to detect the opening force of the deadbolt 100 out of the lock, the deadbolt 100 and the lock are first installed on the locking installation device 2, at this time the deadbolt 100 is inserted in the lock, the tension member of the load application device 3 is selectively connected with the deadbolt 100, the first drive assembly applies a preset load force to the deadbolt 100 through the tensile part, simulates the tension of the safety belt on the deadbolt 100 in the actual operating state, and improves the accuracy of detection. After the first drive assembly applies a preset load force to the deadbolt 100 through the tension part, the deadbolt 100 has not yet detached from the lock, at this time, the second drive assembly drives the bearing seat assembly gradually approaching the locking mounting device 2 and pressing the opening button on the lock, until the deadbolt 100 pops out of the lock, the load sensor 41 automatically detects the pressure exerted by the deadbolt 100 from the lock popping out of the instant bearing seat assembly on the opening button, the pressure is the opening force of the deadbolt 100 on the lock; When it is necessary to detect the insertion force of the deadbolt 100 into the lock, the lock is first installed on the lock mounting device 2, and the deadbolt 100 is installed on the bearing seat assembly, the tension member of the load application device 3 is selectively connected with the lock tongue 100, the first drive assembly applies a preset load force to the lock tongue 100 through the tension piece, simulates the tension of the seat belt on the lock tongue 100 in the actual operating state, and improves the accuracy of detection, at this time, the second drive component drives the bearing seat assembly gradually approaching the lock installation device 2, The deadbolt 100 installed on the bearing seat assembly is inserted into the lock mounted on the lock mounting device 2, and the load sensor 41 automatically detects the insertion force exerted on the deadbolt 100 by the deadbolt 100 when the socket assembly is inserted instantly; The seat belt lock force test equipment using the present embodiment can separately detect the opening force and insertion force of the lock tongue 100 on the lock, reducing the number of testing equipment and reducing the testing cost.

In the present embodiment, the tensile force member of the load application device 3 is selectively connected with the deadbolt 100, which means that the opening force detection and insertion force detection of the deadbolt 100 on the lock have two test situations of loading and not loading, when the opening force detection and insertion force detection of the deadbolt 100 on the lock need to be tested under loading, the first drive assembly applies a tensile force to the deadbolt 100 through the tensile member, When the opening force test and insertion force detection of the deadbolt 100 on the lock do not need to be tested under loading, the first drive assembly does not apply a tensile force.
