[0002] The automotive parts durability testing bench simulates various working conditions of automobiles in actual use to evaluate the durability and reliability of various automotive components. This testing method is of great significance for ensuring the quality and improving the reliability of automotive products. Products that have not undergone durability testing may pose certain safety hazards if left unattended for extended periods.

[0003] Chinese patent CN208333847U discloses a durability testing bench for car seat slide rails. This utility model can automatically detect the durability of the car seat slide rails by allowing them to slide back and forth in the slide groove without interruption. Moreover, it can apply pressure to the seat surface, achieving adjustable pressure, which improves the detection accuracy and avoids the release of defective car seats.

[0004] During operation, the aforementioned equipment mainly relies on the telescopic cylinder's extension and retraction to adjust the sliding rails of the car seat. This single method of adjustment has certain limitations. Due to prolonged repetitive motion and continuous pressure, the telescopic cylinder and its related components may gradually experience fatigue, potentially causing damage to the power equipment before the durability test is completed. This would affect the continuity and stability of the entire testing process, thereby impacting the accuracy and reliability of the equipment's test data. Optimization and improvement are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a durability testing bench for automotive parts, in order to solve the problem that the single movement adjustment method proposed in the background art has certain limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a durability testing bench for automotive parts, comprising: a support platform, a mounting plate connected to the top right side of the support platform, and a test slide rail mounted at the top center of the mounting plate, with a movable slider slidably connected to the top of the test slide rail.

[0007] The telescopic pushing assembly is located on the top left side of the support platform. The telescopic pushing assembly includes a telescopic cylinder, and a side plate is provided on the right side of the telescopic cylinder. A bidirectional adjusting rotating rod is connected to the inner side of the side plate. The telescopic pushing assembly is used for the telescopic pushing of the movable slider.

[0008] The swinging motion component is located on the top right side of the support platform. The swinging motion component includes a swing rod, and a rotating connecting block is connected to the left side of the swing rod. A limit plate is provided at the top of the rotating connecting block. The swinging motion component is used to adjust the swinging back and forth movement of the movable slider.

[0009] Preferably, a counterweight is fixedly connected to the top of the movable slider, and side plates are slidably connected to the left and right ends of the counterweight. The side plates have threaded grooves inside, and plug-in pins are connected to the inner side of the side plates.

[0010] Preferably, the telescopic cylinder is installed on the right side of the mounting plate, and a docking block is connected to the right side of the telescopic cylinder.

[0011] Preferably, the counterweight has an internal connection with a bidirectional adjusting rod, which is used to control the position of the side plate.

[0012] Preferably, a rotating disk is fixedly installed at the top of the support platform, and a connecting column is connected to the front end of the rotating disk, with a swing rod connected to the outside of the connecting column.

[0013] Preferably, a rotating connecting block is connected to the left side of the swing arm, and a slot is provided on the inner side of the counterweight block, and the rotating connecting block is adapted to and engaged with the slot.

[0014] Preferably, positioning blocks are connected to the top left and right sides of the counterweight, and elastic connecting rods are provided on the inner side of the positioning blocks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention achieves the testing effect by sliding the movable slider at the top of the experimental slide rail and pushing it back and forth with the telescopic cylinder. Before fatigue, the back and forth swinging can be replaced by rotating the connecting block of the swing rod. The testing effect is the same, and the two methods can be used interchangeably to avoid testing interruption and ensure the accuracy and reliability of the test data.

[0018] During the replacement of two different durability test power sources, the positioning is achieved through the insertion between the docking block and the side plate, and the sliding of the limiting pressure plate limits the rotational connecting block. This allows for convenient replacement during the testing process, improving the efficiency of the equipment. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 - Figure 4 As shown, this application provides an automotive parts durability testing bench, including: a support platform 1, a mounting plate 2 connected to the top right side of the support platform 1, and an experimental slide rail 3 installed in the middle of the top of the mounting plate 2, with a movable slider 4 slidably connected to the top of the experimental slide rail 3.

[0027] A telescopic pushing assembly is provided on the top left side of the support platform 1. The telescopic pushing assembly includes a telescopic cylinder 10, and a side plate 6 is provided on the right side of the telescopic cylinder 10. A bidirectional adjusting rod 9 is connected to the inner side of the side plate 6. The telescopic pushing assembly is used to push the movable slider 4 telescopically.

[0028] Specifically, such as Figure 3As shown, a counterweight 5 is fixedly connected to the top of the movable slider 4, and side plates 6 are slidably connected to the left and right ends of the counterweight 5. A threaded groove 7 is provided inside the side plate 6, and a plug-in post 8 is connected to the inner side of the side plate 6. The back-and-forth movement of the side plate 6 can control the plug-in post 8 to be inserted into and fixed to the docking block 11. The threaded groove 7 is provided in the rotating shaft inside the side plate 6, and is used to cooperate with the bidirectional adjusting rod 9 for rotation adjustment.

[0029] Specifically, such as Figure 3 As shown, the telescopic cylinder 10 is installed on the right side of the mounting plate 2, and the right side of the telescopic cylinder 10 is connected to the docking block 11. The telescopic cylinder 10 pushes the docking block 11 to control the sliding of the movable slider 4 back and forth. The end of the docking block 11 is provided with a hole that is adapted to the plug-in post 8.

[0030] Specifically, such as Figure 3 As shown, the counterweight 5 is internally connected to a bidirectional adjusting rod 9, which is used to control the position of the side clamping plate 6. The rotation of the bidirectional adjusting rod 9 can cause the side clamping plates 6 on both sides to move closer or further apart.

[0031] A swinging motion component is provided on the top right side of the support platform 1. The swinging motion component includes a swing rod 14, and a rotating connecting block 15 is connected to the left side of the swing rod 14. A limit pressure plate 18 is provided at the top of the rotating connecting block 15. The swinging motion component is used to adjust the swinging back and forth movement of the movable slider 4.

[0032] Specifically, such as Figure 2 As shown, a rotating disk 12 is fixedly installed at the top of the support platform 1, and a connecting column 13 is connected to the front end of the rotating disk 12. A swing rod 14 is connected to the outside of the connecting column 13. When the rotating disk 12 rotates, it drives the connecting column 13 to rotate in a circular motion, so that the swing rod 14 swings up and down with the connecting column 13, controlling the movable slider 4 to slide back and forth.

[0033] Specifically, such as Figure 4 As shown, a rotating connecting block 15 is connected to the left side of the swing arm 14, and a slot 16 is provided on the inner side of the counterweight block 5. The rotating connecting block 15 is adapted to engage with the slot 16. The rotating connecting block 15 is engaged inside the slot 16, restricting movement in directions other than upward.

[0034] Specifically, such as Figure 4 As shown, positioning blocks 17 are connected to the top left and right sides of the counterweight 5, and an elastic connecting rod 20 is provided on the inner side of the positioning block 17. The elastic connecting rod 20 can slide on the inner side of the positioning block 17, and the limiting pressure plate 18 is reset through the elastic connection.

[0035] Specifically, such as Figure 4As shown, the inner side of the positioning block 17 is connected to a limiting pressure plate 18, and the inner side of the limiting pressure plate 18 is connected to a magnetic block 19. The limiting pressure plate 18 moves inward under the push of the elastic force and is fixed by the adsorption of the magnetic block 19, thus restricting the upward movement of the rotating connecting block 15.

[0036] In this embodiment: by sliding the movable slider 4 at the top of the experimental slide rail 3, the telescopic cylinder 10 can push it back and forth to achieve the detection effect. Before fatigue, the swing rod 14 can be used to swing back and forth to replace the rotating connecting block 15. The detection effect is the same, and it can be used interchangeably to avoid interruption of the detection. In the process of replacing two different durability test power, the positioning is achieved by the insertion between the docking block 11 and the side plate 6, and the sliding of the limiting pressure plate 18 limits the rotating connecting block 15. Both can be easily replaced, improving the convenience of use and replacement between different methods.

[0037] The specific solution is as follows: When conducting durability tests on automotive seat slide rails, the test effect is achieved by the back-and-forth sliding of the movable slider 4 at the top of the test slide rail 3. The back-and-forth pushing of the telescopic cylinder 10 can drive the counterweight 5 and the movable slider 4 to move for testing. The docking block 11 is restricted by the insertion post 8 and is locked inside by the side clamping plate 6. At this time, the rotating connecting block 15 is not connected to the slot 16. When the test of the telescopic cylinder 10 reaches the fatigue time, the bidirectional adjustment rod 9 can be rotated to move the side clamping plate 6 to both sides, thereby causing the docking block 11 to disengage from the counterweight 5. At this time, the rotating connecting block 15 is locked inside, and then the limiting pressure plate 18 is reset under the elastic support of the elastic connecting rod 20, limiting the top of the rotating connecting block 15. The connection of the magnetic suction block 19 ensures the connection stability of the limiting pressure plate 18. After connection, the rotation of the rotating disk 12 drives the swing rod 14 to swing back and forth, thereby driving the movable slider 4 to move. By replacing the two different methods for testing, the efficiency of use is improved, and the service life of the equipment is also ensured.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
