Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile safety belt adjusting devices, in particular to an operation durability testing device for automobile safety belt adjusting devices. Background Art
[0002] Currently, automotive seat belt adjusters are mounted on the vehicle's pilasters. When the locking tongue is pressed and unlocked, it slides up and down the pilaster to adjust the height to accommodate passengers of varying body shapes. When the locking tongue is not pressed, it engages with a buckle on the pilaster, securing the seatbelt's height. Because seat belt adjusters may experience a high frequency of up-and-down motion during use, automotive parts manufacturers conduct durability tests to simulate the actual operating conditions of seat belt adjusters. This allows them to assess their reliability, reduce or even eliminate the use of defective products in the vehicle, lower the likelihood and cost of subsequent repairs, and ultimately improve the overall quality of the vehicle. However, existing equipment for testing the operational durability of seat belt adjusters suffers from low efficiency and high costs. Utility Model Content

During testing, the clamping cylinder drives the left and right clamping jaws to clamp the locking tongue of the car seat belt adjuster. After the locking tongue is clamped, it is unlocked and can slide freely up and down on the wall column. Then, the lifting motor drives the lifting screw to rotate. The lifting screw rotation drives the lifting slider and the clamping cylinder to rise and fall together, thereby driving the clamping cylinder and the locking tongue to rise and fall together. The locking tongue is constantly engaged and withdrawn from the slot, ultimately achieving the operational durability test of the seat belt adjuster. The utility model has a simple structure, low testing cost, and high testing efficiency.

[0015] Figure 2 The utility model is a control schematic diagram of an operating durability test device for an automobile safety belt adjusting device. DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Example 1, as Figure 1As shown, an operational durability test device for an automobile seat belt adjustment device includes a controller 11, a support frame 1, a clamping cylinder 2, a lifting screw 4, a lifting motor 3, a lifting slider 5, and an adjustment device fixing frame 6. The support frame 1 and the adjustment device fixing frame 6 are arranged opposite each other and spaced apart. The lifting screw 4 is vertically mounted on the support frame 1. The lifting motor 3 is mounted on the support frame 1 and drives the lifting screw 4 to rotate. The lifting slider 5 is threadedly connected to the lifting screw 4. The lifting slider 5 is mounted on the support frame 1 and slides up and down. The clamping cylinder 2 is mounted on the lifting slider 5 and is located between the support frame 1 and the adjustment device fixing frame 6. The clamping cylinder 2 drives the left clamping jaw 21 and the right clamping jaw 22 thereon to close or open. The automobile seat belt adjustment device and its locking tongue are prior art, and their structure and principle will not be described in detail here.
[0018] As a more specific technical solution of the utility model.
[0019] The support frame 1 and the adjustment device fixing frame 6 are integrally arranged.
[0020] The support frame 1 is provided with a lifting guide rail 7 along the height direction, and the lifting slider 5 is provided on the lifting guide rail 7 for sliding up and down.
[0021] The support frame 1 is connected to the adjustment device fixing frame 6 in a U-shape.
[0022] The controller 11 is electrically connected to the gripper cylinder 2 and the lifting motor 3 respectively.
[0023] The controller 11 is provided with operation buttons 14 and a counting display screen 12 .
[0024] The working principle of this utility model is:
[0025] Before testing the present invention, the worker first installs the car seat belt adjusting device on the adjusting device fixing frame 6. During the testing of the present invention, the worker manipulates the operation button on the controller, and the controller sends a signal to the clamping cylinder 2 and the lifting motor 3. The clamping cylinder 2 first drives the left clamping jaw 21 and the right clamping jaw 22 thereon to clamp the lock tongue 8 of the car seat belt adjusting device. After the lock tongue 8 is clamped, it is unlocked, and the lock tongue 8 can slide freely up and down on the wall column. At the same time, the controller sends a signal to the lifting motor 3, and the lifting motor 3 drives the lifting screw 4 to rotate forward. The lifting screw 4 rotates forward to drive the lifting slider 5 and the clamping cylinder 2 to rise, thereby driving the clamping cylinder 2 and the lock tongue 8 to rise together, and the lock tongue 8 is stuck in the slot 9 on the car seat belt adjusting device. Then the clamping cylinder 2 drives its left clamping jaw 21 and right clamping jaw 22 to release the lock tongue 8, and the lock tongue 8 is stuck in the slot 9. As the locking tongue 8 rises, it continuously engages and exits each slot 9. When the locking tongue 8 engages the top slot 9 on the car's seat belt adjustment device, the controller sends a signal to the lifting motor 3, which starts to drive the lifting screw 4 to rotate in the opposite direction. The lifting screw 4 rotates in the opposite direction, driving the lifting slider 5 and the clamping cylinder 2 to descend. The locking tongue 8 engages and exits each slot 9 one by one until the locking tongue returns to the bottom slot 9. This action is completed once as one cycle. The controller sends a signal to the counting display 12, which displays the number of tests. With the cooperation of the clamping cylinder 2 and the lifting motor 3, the locking tongue 8 is lifted and lowered multiple times, engaged in and exited from the slot 9. The counting display 12 displays the number of times until the set number is reached, ultimately achieving the test of the operational durability of the seat belt adjustment device.
