Description

Technical Field

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

[0002] With the continuous increase in global car ownership and increasingly stringent consumer demands for car quality, car seats, as a key component directly related to driving comfort and safety, have received unprecedented attention. After manufacturing, car seats need to be subjected to pressure testing using compression testing equipment to check whether the produced car seats meet the standards. The seats should not suffer structural damage or performance degradation due to frequent compression and friction, otherwise it may affect the protective effect during emergency braking and collisions. In the existing technology, compression testing institutions are mostly designed for single-specification seats and cannot be well adapted to different types of seats, leading to deviations in the test results.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the drive motor, threaded rod, guide rod, and placement plate, the drive motor drives the threaded rod to rotate, and the threaded rod meshes with the placement thread, which can slide the placement plate on the side of the guide rod. The placement plate structure is in a wider space, which makes it easier for staff to quickly change the seat to be tested, thus improving work efficiency. Through the cooperation of the positioning plate, rotating motor, pulley, and active rod structure, the pulley structure reduces the friction between the seat and the placement plate, avoiding wear on the seat during installation and replacement, and making replacement easier and reducing workload.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: an automotive seat compression resistance testing mechanism, including a base 1, a connecting frame 2 fixedly installed on the top of the base 1, a top plate 3 fixedly installed on the top of the connecting frame 2, a telescopic mechanism 4 installed on the top of the top plate 3, and a pressure plate 5 installed at the bottom of the telescopic mechanism 4 via a telescopic rod. A fixed seat 6 is fixedly installed on the top of the base 1, and a guide groove 7 is provided on the side of the fixed seat 6. A clamping assembly is slidably connected in the guide groove 7. A seat body 8 is placed on the top of the clamping assembly. The bottom of the pressure plate 5 can press against the working surface of the seat body 8. The telescopic mechanism 4 activates the telescopic rod 4, and the telescopic rod 4, along with the pressure plate 5, performs a compression test on the seat body 8.

[0018] A drive motor 9 is fixedly installed on the side of the fixed base 6. A threaded rod 10 is fixedly connected to the output end of the drive motor 9. Two positioning rods 11 are fixedly installed on the side of the fixed base 6. The drive motor 9 drives the threaded rod 10 to rotate. The threaded rod 10 engages with the placement plate 12, which can slide along the side of the guide rod with the placement plate 12, making it easy to quickly change the seat to be tested and improving work efficiency.

[0019] The clamping assembly includes a placement plate 12, the top of which is fitted to the seat body 8, the side of which is inserted into the threaded rod 10, and the placement plate 12 and the positioning rod 11 are slidably inserted into each other.

[0020] Multiple sets of pulleys 13 are fixedly installed on the top of the placement plate 12. The pulleys 13 slide in cooperation with the bottom of the seat body 8. A groove 14 is provided on the top of the placement plate 12. A slider 15 slides in cooperation with the top of the groove 14. A positioning plate 16 is fixedly connected to the top of the slider 15. The pulley 13 structure reduces the friction between the seat and the placement plate 12, avoids wear on the seat during installation and replacement, and reduces work losses.

[0021] An active rod 17 is slidably inserted into the side of the slider 15. A rotary motor 18 is synchronously installed on the side of the active rod 17. A limiting slide plate 19 is fixedly installed on the end side of the guide rod. The limiting slide plate 19 is in sliding fit with the guide groove 7. The rotary motor 18 drives the active rod 17 to rotate. The active rod 17 is threadedly engaged with the slider 15, causing the slider 15 to slide in the slide groove 14. The slider 15 also moves the top positioning plate 16. The positioning plate 16 clamps and fixes the car seat. It can not only actively adapt to the type of seat and improve the application range of the equipment, but also avoid seat displacement and vibration during the compression test, thus improving the accuracy of the test results.

[0022] In use, first, start the drive motor 9. The drive motor 9 drives the threaded rod 10 to rotate. The threaded rod 10 engages with the placement plate 12, allowing the placement plate 12 to slide along the side of the guide rod. After the placement plate 12 moves to a wide position, the seat to be tested is placed on top of the placement plate 12. During this process, the pulley 13 structure reduces friction between the seat and the placement plate 12, preventing wear on the seat during installation and replacement. Then, start the rotating motor 18 to drive the active rod 17. The active rod 17 engages with the slider 15, causing the slider 15 to slide within the slide groove 14. The slider 15 then moves the top positioning plate 16. At this time, the positioning plate 16 clamps and fixes the car seat, preventing the seat from shifting and shaking during the compression test, thus improving the accuracy of the test results. Finally, reverse the drive motor 9, causing the placement plate 12 to return to the original working area with the seat. Start the telescopic machine 4, which drives the telescopic rod 4 to extend and retract. The telescopic rod 4 lowers the bottom pressure plate 5 structure, beginning the compression test on the seat body 8.
