Description

Technical Field

[0001] This utility model relates to the field of automotive seat durability testing technology, specifically an automotive seat durability testing device. Background Technology

[0002] After the automotive seats are manufactured, random sampling of the same batch is required to assess their durability, such as the durability of the seat rails. During the rail durability test, the rail mounting bracket at the bottom of the seat is securely installed on the test bench, and then connected to the automotive seat via a cylinder. The cylinder pushes the seat, causing it to reciprocate, thus simulating actual usage conditions and testing the durability of the rails.

[0003] However, in the existing testing process, the installation of the seat rails and the test bench typically relies on multiple bolts for fixation. After each test, removing the old seats and installing a new batch of seats to be tested takes a considerable amount of time, which not only affects operational efficiency but also reduces the overall pace and productivity of the testing work to some extent. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an automotive seat durability testing device, which can improve the efficiency of seat durability testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car seat durability testing device, comprising a testing mounting platform on which a seat cushion is installed, a push cylinder connected to the top of the testing mounting platform, and a cylinder rod connected to the end of the push cylinder. A mounting plate is fixedly installed on the top of the testing mounting platform. Two push grooves are formed on the top of the mounting plate. Push blocks are slidably connected in the two push grooves. A mounting block fixedly connected to the push cylinder is fixedly connected to the top surface of the push block. An end block is fixedly connected to the end of the cylinder rod. A limiting structure for limiting the push cylinder is connected to the outside of the mounting plate.

[0006] Furthermore, the limiting structure includes a U-shaped insert rod, and the top of the mounting plate has two sets of symmetrically arranged slots. The U-shaped insert rod is sleeved on the outside of the push cylinder, and the bottom of the U-shaped insert rod is inserted into the slot.

[0007] Furthermore, a pull ring is fixedly connected to the top of the U-shaped plug.

[0008] Furthermore, the outer side of the seat cushion is connected to a connecting structure, which includes two U-shaped sleeves. The two U-shaped sleeves are fitted onto the seat cushion. Each of the two horizontal plates of the U-shaped sleeves is fixedly connected to a strap. One end of one strap is fixedly connected to a fastening strap, and one end of the fastening strap passes through and connects to the other strap.

[0009] Furthermore, the inner wall of the fastening band and the outer wall of the binding band are connected by Velcro tape.

[0010] Furthermore, a quick-release structure is provided between the end block and the U-shaped sleeve. The quick-release structure includes a T-shaped insert fixedly connected to the cylinder rod, an integral plate fixedly connected between the two U-shaped sleeves, a connecting block fixedly connected to the outer wall of the integral plate, and connecting grooves corresponding to the T-shaped inserts are provided at both ends of the connecting block.

[0011] Furthermore, both ends of the T-shaped insert are chamfered.

[0012] Furthermore, both sides of the bottom of the U-shaped plug are chamfered.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features two testing stations on a testing and installation platform, with a pushing groove on the mounting plate that engages with a pushing block at the bottom of the mounting block. This structural design allows the pushing cylinder to move flexibly on the mounting plate, moving its cylinder rod to the rear of the seat to be tested and connecting there.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a car seat durability testing device includes a testing mounting platform 1 on which a seat cushion 10 is mounted, a push cylinder 2 connected to the top of the testing mounting platform 1, and a cylinder rod 3 connected to the end of the push cylinder 2. A mounting plate 4 is fixedly mounted on the top of the testing mounting platform 1. Two push grooves 5 are opened on the top of the mounting plate 4. Push blocks 14 are slidably connected in the two push grooves 5. A mounting block 6 fixedly connected to the push cylinder 2 is fixedly connected to the top surface of the push block 14. An end block 8 is fixedly connected to the end of the cylinder rod 3. A limiting structure for limiting the push cylinder 2 is connected to the outside of the mounting plate 4.

[0023] like Figures 1 to 5 As shown, when using the automotive seat durability testing device of this utility model, while one seat is being tested, another seat to be tested can be installed on the testing platform 1 first. After the seat being tested has been tested, the cylinder rod 3 at the front end of the push cylinder 2 is separated from the seat cushion 10, and the limiting structure is opened, so that the push cylinder 2 is no longer restricted. The push cylinder 2 can then be pushed, causing the push cylinder 2 to drive the cylinder rod 3 to the rear of the new seat to be tested. Then, the end of the cylinder rod 3 is installed on the seat cushion 10. When the push cylinder 2 moves, it drives the push block 14 at the bottom of the mounting block 6 to move in the push groove 5. Then, the seat that has been tested can be removed without stopping the push cylinder 2.

[0024] By setting two inspection stations on the inspection and installation platform 1, and providing a sliding groove 5 on the mounting plate 4 to cooperate with the sliding block 14 at the bottom of the mounting block 6, the sliding groove 5 preferably has a dovetail groove structure to ensure sliding stability. The bottom of the mounting block 6 is a slider that cooperates with the dovetail groove. Through this structural design, the pushing cylinder 2 can move flexibly on the mounting plate 4 and move the cylinder rod 3 to the rear of the seat to be inspected and connect with it, realizing the continuity of alternating inspection between the two inspection stations. The disassembly of one seat and the installation of another seat can be completed without interrupting the operation of the pushing cylinder 2, thereby significantly improving inspection efficiency and overall work rhythm.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the limiting structure includes a U-shaped insert rod 13. The top of the mounting plate 4 has two sets of symmetrically arranged slots 7. The U-shaped insert rod 13 is sleeved on the outside of the push cylinder 2, and the bottom of the U-shaped insert rod 13 is inserted into the slot 7.

[0026] Specifically, in order to make it easier to fix the push cylinder 2 after it moves on the mounting plate 4, a U-shaped insert 13 can be sleeved on the outside of the push cylinder 2, and then the U-shaped insert 13 is inserted into the slot 7 on the mounting plate 4. This ensures that the push cylinder 2 will not move on the mounting plate 4. In practical applications, there can be two U-shaped inserts 13 to ensure the stability of the push cylinder 2 on the mounting plate 4.

[0027] like Figure 3 and Figure 4 As shown, a pull ring 16 is fixedly connected to the top of the U-shaped plug 13. The pull ring 16 facilitates the pulling up of the U-shaped plug 13.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a connecting structure is connected to the outside of the seat cushion 10. The connecting structure includes two U-shaped sleeves 12. The two U-shaped sleeves 12 are fitted onto the seat cushion 10 of the seat. Both horizontal plates of the U-shaped sleeves 12 are fixedly connected to straps 9. One end of one strap 9 is fixedly connected to a fastening strap 19, and one end of the fastening strap 19 passes through the other strap 9 and is connected to it.

[0029] like Figure 4 and Figure 5 As shown, the inner wall of the fastening strap 19 and the outer wall of the binding strap 9 are connected by Velcro tape 20.

[0030] like Figure 2 and Figure 4 As shown, a quick-release structure is connected between the end block 8 and the U-shaped sleeve 12. The quick-release structure includes a T-shaped insert 15 that is fixedly connected to the cylinder rod 3. An integral plate 18 is fixedly connected between the two U-shaped sleeves 12. A connecting block 11 is fixedly connected to the outer wall of the integral plate 18. Both ends of the connecting block 11 are provided with connecting grooves 17 corresponding to the T-shaped insert 15.

[0031] Specifically, in order to facilitate quick disassembly of the end block 8 at the end of the seat cushion 10 and the cylinder rod 3, when the cylinder rod 3 moves, the T-shaped insert 15 will disengage from the connecting groove 17 on the connecting block 11 on one of the U-shaped sleeves 12, and under the movement, it will be inserted into the connecting groove 17 on the connecting block 11 on the back of another seat cushion 10 to be tested. In this way, the left and right pushing and changing of the cylinder rod 3 is completed.

[0032] When the cylinder rod 3 extends or retracts, the T-shaped insert 15 moves back and forth with the connecting block 11, which in turn drives the seat cushion 10 to move back and forth.

[0033] To ensure that the end block 8 can smoothly drive the seat cushion 10, two U-shaped sleeves 12 can be put on one end of the seat cushion 10, and then two cable ties 9 can be wrapped around the front end of the seat cushion 10. After taking the fastening strap 19 at the end of one of the cable ties 9 and passing it through the other cable ties 9, it can be fixed with Velcro 20. In this way, when the cylinder rod 3 is pulled, the U-shaped sleeve 12 will be fixed by the two cable ties 9, which will pull the seat cushion 10 to return to its original position.

[0034] like Figure 4 As shown, both ends of the T-shaped plug 15 are chamfered. This design allows the T-shaped plug 15 to be inserted into the connecting slot 17 more smoothly.

[0035] like Figure 4 As shown, both sides of the bottom of the U-shaped plug 13 are chamfered. This design makes it easier for the U-shaped plug 13 to be inserted into the slot 7.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
