Detailed Implementation

[0028] The present invention will be further described below with reference to embodiments.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0031] Please see Figures 1-5 This invention provides a testing device for the durability performance of automotive seat slide rails, including a work frame 1, a base plate 2, the base plate 2 being fixed to the bottom side wall of the work frame 1, a bracket 3 being slidably connected to the top side wall of the base plate 2, a cylinder a4 being fixed to the bottom side wall of the bracket 3, a connecting plate 5 being fixed to the output end of the cylinder a4, a pressure block 6 being fixed to the bottom side wall of the connecting plate 5, an auxiliary component 7 being provided on one side of the connecting plate 5, a slide rail body 8 being provided at the top of the work frame 1, an adjustment component 9 adapted to the bracket 3 being provided on one side of the work frame 1, two symmetrically distributed support plates 10 being fixed to the outer side wall of the work frame 1, a bearing plate 11 being fixed to one side wall of one of the support plates 10, a cylinder b12 being fixed to the top side wall of the bearing plate 11, and a clamping component 13 being provided at the output end of the cylinder b12.

[0032] Further as Figure 5 As shown, it is worth noting that the auxiliary component 7 includes multiple connecting rods 71, which are symmetrically distributed and slide through one side wall of the connecting plate 5. A collar 72 is fixed to the top of the connecting rod 71, and a pulley 73 is fixed to the other end of the connecting rod 71. A spring 74 is sleeved on the outer surface of the connecting rod 71. One end of the spring 74 is fixed to the pulley 73, and the other end of the spring 74 is fixed to the bottom side wall of the connecting plate 5. By setting up the auxiliary component 7, it can play a buffering role when the pressure block 6 applies pressure to the inside of the slide rail body 8, which greatly improves the stability of the pressure block 6 when moving inside the slide rail body 8, avoids jamming when the pressure block 6 moves, and effectively improves the durability performance test effect of the slide rail body 8.

[0033] Further as Figure 1 and Figure 2 As shown, it is worth noting that multiple pulleys 73 are located directly above the slide rail body 8, and the pressure block 6 is adapted to the inner side of the slide rail body 8.

[0034] This solution includes the following working process: When testing the durability of a car seat slide rail, the slide rail body 8 is placed on the top surface of the work frame 1, ensuring that one end of the slide rail body 8 is in contact with one side of the push plate 131. By rotating the knob 134, the screw 133 rotates synchronously. Utilizing the threaded transmission between the screw 133 and the threaded sleeve 132, the pressure plate 135 is forced and moves along the slide groove 15 until the pressure plate 135 contacts the outer side of the slide rail, thus achieving the positioning of the slide rail. Driven by the cylinder b12, the push plate 131 moves the slide rail body 8, ensuring that the slide rail body 8 is completely below the cylinder a4. Driven by the cylinder a4, the connecting plate 5... The movement proceeds synchronously until the outer surface of pulley 73 contacts one side of the slide rail. Utilizing the downward pressure of cylinder a4 and the elasticity of spring 74, the pulley 73 and slide rail body 8 are ensured to be in contact, as are the pressure block 6 and slide rail body 8. Driven by servo motor 96, threaded rod 92 rotates synchronously. Through the transmission of pulley 94 and belt 95, the two threaded rods 92 rotate synchronously. The threaded transmission between the threaded rod 92 and the threaded hole causes the bracket 3 to move under force, thereby driving cylinder a4 to move synchronously. Durability and pressure resistance tests are performed on slide rail body 8 based on the different output pressures of cylinder a4.

[0035] As can be seen from the above working process: the auxiliary component 7 can buffer the pressure applied by the pressure block 6 to the inside of the slide rail body 8, greatly improving the stability of the pressure block 6 when moving inside the slide rail body 8, avoiding jamming when the pressure block 6 moves, and effectively improving the durability performance test effect of the slide rail body 8. The clamping component 13 can load and install the slide rail body 8, thereby improving its stability during durability testing and effectively improving the accuracy of placing the slide rail body 8, avoiding positional deviation, and improving the efficiency of durability performance testing to a certain extent. The adjusting component 9 can adjust the moving speed of the pressure block 6 inside the slide rail body 8 in real time, and can complete the durability performance test of the slide rail body 8 in the whole process, avoiding the impact of dead angles in the movement of the pressure block 6 on the durability test of the slide rail body 8.

[0036] Further as Figure 2 and Figure 4As shown, it is worth noting that the adjustable distance component 9 includes bearing seats 91, and multiple bearing seats 91 are provided. The multiple bearing seats 91 are symmetrically distributed and fixed to the outer side wall of the work frame 1. A threaded rod 92 is rotatably connected inside the bearing seat 91. A threaded hole 93 is opened on one side wall of the bracket 3. The threaded hole 93 is threadedly connected to the threaded rod 92. A pulley 94 is provided between the two threaded rods 92. A belt 95 is sleeved on the outer surface of the two pulleys 94. A load-bearing plate 97 is fixed on one side wall of the work frame 1. A servo motor 96 is fixed on one side wall of the load-bearing plate 97. The output shaft of the servo motor 96 is coaxially fixed with one of the threaded rods 92. Through the setting of the adjustable distance component 9, the moving speed of the pressure block 6 inside the slide rail body 8 can be adjusted in real time. Moreover, the durability performance test of the slide rail body 8 can be completed in its entirety, avoiding the impact of dead angles in the movement of the pressure block 6 on the durability test of the slide rail body 8.

[0037] Further as Figure 2 As shown, it is worth noting that two symmetrically distributed guide grooves 14 are provided on the top side wall of the base plate 2. The bracket 3 is slidably connected to the guide groove 14. By sliding the bracket 3 inside the guide groove 14, it can not only guide and limit the bracket 3, but also effectively improve the stability of the bracket 3 when it moves.

[0038] Further as Figure 3 As shown, it is worth noting that the clamping assembly 13 includes a push plate 131, which is fixed to the output end of the cylinder b12. Two symmetrically distributed threaded sleeves 132 are fixed to one side wall of the push plate 131. A screw 133 is threadedly connected inside the threaded sleeve 132. A knob 134 is fixed to one end of the screw 133, and a pressure plate 135 is rotatably connected to the other end of the screw 133. The pressure plate 135 is slidably connected to one side wall of the push plate 131. By setting up the clamping assembly 13, the slide rail body 8 can be loaded and installed, thereby improving its stability during durability testing. It can also effectively improve the accuracy of placing the slide rail body 8, avoiding positional deviation, and improving the efficiency of durability performance testing of the slide rail body 8 to a certain extent.

[0039] Further as Figure 5 As shown, it is worth noting that two symmetrically distributed sliding grooves 15 are provided on one side wall of the push plate 131. The pressure plate 135 is slidably connected to the inside of the sliding groove 15. By sliding the pressure plate 135 inside the sliding groove 15, it can not only guide and limit the pressure plate 135, but also effectively improve the stability of the pressure plate 135 when it moves.

[0040] Further as Figure 2As shown, it is worth noting that two symmetrically distributed reinforcing rods 16 are fixed to the bottom side wall of the support plate 10. The other end of the reinforcing rod 16 is fixed to one side wall of the work frame 1. The reinforcing rods 16 and the support plate 10 are arranged at an incline. By setting the reinforcing rods 16, the stability of the support plate 10 can be effectively increased, thereby increasing the load-bearing capacity of the support plate 10.

[0041] In summary: the sliding of the bracket 3 within the guide groove 14 not only guides and limits the bracket 3, but also effectively improves the stability of the bracket 3 during movement. Similarly, the sliding of the pressure plate 135 within the slide groove 15 not only guides and limits the pressure plate 135, but also effectively improves the stability of the pressure plate 135 during movement. Furthermore, the addition of the reinforcing rod 16 effectively increases the stability of the support plate 10, thereby increasing the load-bearing capacity of the support plate 10.

[0042] Cylinder a4, servo motor 96, and cylinder b can all be purchased commercially. Cylinder a4, servo motor 96, and cylinder b are all equipped with power supplies. These are mature technologies in the field and have been fully disclosed, so they will not be repeated in the specification.
