[0002] In daily use, drivers and passengers frequently enter and exit the car, and the seat needs to withstand various pressures and impact forces. If the seat structure becomes loose or damaged during multiple entries and exits, the seat cannot provide stable support for the driver and passengers when the vehicle is running, especially in case of emergency braking, collision, etc. Therefore, it is necessary to conduct durability tests on it.

[0003] After retrieval, the patent document with the publication number CN215065267U discloses a durability test device for automobile seat entry and exit. The test device uses a first lead screw drive mechanism to drive the mounting frame to move left and right along the guide column to achieve left and right position adjustment; uses a second lead screw drive mechanism to drive the first adapter frame to move up and down, and uses a third lead screw drive mechanism to drive the second adapter frame to move up and down to achieve up and down adjustment; uses a fourth lead screw drive mechanism to drive the third adapter frame to move back and forth to achieve front and back adjustment; uses a first servo motor to drive the gear to rotate on the rack to adjust the orientation of the second telescopic cylinder; through the adjustment of left and right, up and down, front and back and angle, the seat cushion pressing plate is aligned with the seat cushion test part of the automobile seat, and the backrest pressing plate is aligned with the backrest test part of the automobile seat, so as to adjust the positions of the seat cushion pressing plate and the backrest pressing plate, making the device applicable to different models of automobile seats; then uses a first telescopic cylinder to drive the seat cushion pressing plate to press the seat cushion of the automobile seat, and uses a second telescopic cylinder to drive the backrest pressing plate to press the backrest of the automobile seat to conduct the durability test of the automobile seat entry and exit.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-5 , an automobile seat entry and exit durability test device, including a test rack 1. At the lower end inside the test rack 1, a placement plate 2 is fixedly provided for placing the automobile seat to be tested, providing a bearing platform for the seat to ensure the seat is in a stable state during the test. At the upper end inside the test rack 1, there are two symmetrically arranged connecting plates 3. At the bottom of both connecting plates 3, fixed plates 4 are fixedly provided. On the side wall of the fixed plate 4, a side pressure block 5 is in contact, which contacts the side of the seat, simulating the friction and extrusion between the driver and passenger and the side of the seat when entering and exiting, and detecting the durability of the side of the seat. In the middle of the inner wall of the test rack 1, two symmetrically arranged support plates 6 are fixedly provided. Between the two support plates 6, a support frame 7 is fixedly provided. Inside the support frame 7, a dual-axis drive mechanism is provided, and a vertical plate 8 and a vertical rod 9 are provided through the dual-axis drive mechanism. At the bottom of the vertical rod 9, a bottom pressure block 10 is fixedly provided, which contacts the bottom of the seat, applying pressure to the bottom of the seat, simulating the force exerted on the bottom of the seat when the driver and passenger sit down, and detecting the durability of the bottom of the seat. At the lower end of the outer wall of the vertical plate 8, a back pressure block 11 is fixedly provided, which contacts the back of the seat, applying pressure to the back of the seat, simulating the force exerted on the back of the seat when the driver and passenger lean on the seat, and detecting the durability of the back of the seat. Between the two connecting plates 3 and the test rack 1, a synchronous drive mechanism is provided. The synchronous drive mechanism is used to drive the two side pressure blocks 5 to move synchronously. The synchronous drive mechanism includes a bidirectional lead screw 12. The bidirectional lead screw 12 is rotatably arranged at the upper end inside the test rack 1. Both connecting plates 3 are threadedly sleeved on the rod wall of the bidirectional lead screw 12. A motor 13 is fixedly provided on the outer wall of the test rack 1. The output shaft of the motor 13 passes through the test rack 1 and is fixedly connected to the bidirectional lead screw 12. A strip-shaped hole 14 is opened at the top of the test rack 1. Inside the strip-shaped hole 14, two symmetrically arranged sliding plates 15 are slidably penetrated. The two sliding plates 15 are respectively fixedly provided at the tops of the two connecting plates 3. The strip-shaped hole 14 is opened at the top of the test rack 1. The sliding plate 15 is fixedly connected to the connecting plate 3 and slides inside the strip-shaped hole 14, playing a guiding and limiting role in the movement of the connecting plate 3 to ensure the stable and accurate movement of the connecting plate 3.

[0024] An adjusting and squeezing mechanism is provided between the fixing plate 4 and the side pressing block 5. The adjusting and squeezing mechanism is used to adjust the pushing pressure of the side pressing block 5. The adjusting and squeezing mechanism includes a first electromagnetic block 16 and a second electromagnetic block 17. The sides of the first electromagnetic block 16 and the second electromagnetic block 17 that are close to each other have opposite magnetic polarities. As the core components of the adjusting and squeezing mechanism, the magnetic force between the two is adjusted by changing the magnitude of the current, and then the pushing pressure of the side pressing block 5 on the side of the seat is adjusted to simulate the acting forces of the driver and passengers on the side of the seat in different situations. The first electromagnetic block 16 is fixedly arranged at the upper end of the side wall of the fixing plate 4, and the second electromagnetic block 17 is fixedly arranged at the top of the side pressing block 5. A guiding hole 18 is opened at the lower end inside the fixing plate 4. A guiding block 19 is slidably inserted into the guiding hole 18. The cross-section of the guiding block 19 is in a T shape. The guiding block 19 is fixedly connected to the side pressing block 5. A pushing spring 20 is fixedly arranged between the guiding block 19 and the inner wall of the guiding hole 18. A support rod 21 is fixedly arranged at the bottom of the inner wall of the guiding hole 18. The support rod 21 is slidably inserted into the inside of the pushing spring 20 and the guiding block 19. The guiding hole 18 is opened inside the fixing plate 4. The guiding block 19 slides in the guiding hole 18 and is fixedly connected to the side pressing block 5. The pushing spring 20 provides an elastic force. They work together to enable the side pressing block 5 to stably apply pressure to the side of the seat under the control of the adjusting and squeezing mechanism and to move flexibly when the magnetic force changes. The support rod 21 plays a role in supporting and limiting the pushing spring 20 to prevent the spring from being distorted during the stretching and contracting process and to ensure the stable operation of the adjusting and squeezing mechanism.

[0025] The biaxial drive mechanism includes a drive screw 22. The drive screw 22 is rotatably arranged on the side of the support frame 7, and first threads and second threads are respectively provided at both ends. An internally threaded tube 23 is threadedly sleeved on the second threaded end of the drive screw 22. The internally threaded tube 23 is fixedly penetrated through the inside of the vertical plate 8. A limiting rod 24 is fixedly arranged at the end of the internally threaded tube 23. The limiting rod 24 is slidably penetrated through the side of the support frame 7 to limit the movement directions of the internally threaded tube 23 and the vertical plate 8. A push block 25 is threadedly sleeved on the first threaded end of the drive screw 22. The push block 25 is cooperated with a moving block 26. The top of the push block 25 is in contact and cooperation with the top inner wall of the support frame 7. The inclined surfaces are arranged on both sides where the push block 25 and the moving block 26 are cooperated. The inclined surface design on both sides where the push block 25 and the moving block 26 are cooperated converts the horizontal movement of the push block 25 into the up-and-down movement of the moving block 26, thereby driving the vertical rod 9 to move. The moving block 26 is fixedly arranged at the top of the vertical rod 9. A return spring 27 is sleeved on the rod wall of the vertical rod 9. Both ends of the return spring 27 are fixedly connected to the vertical rod 9 and the support frame 7 respectively. A transmission rod 28 is rotatably penetrated through the inside of the support frame 7. First bevel gears 29 and second bevel gears 30 are respectively fixedly arranged at both ends of the rod wall of the transmission rod 28. Third bevel gears 31 and fourth bevel gears 32 are respectively cooperated with the first bevel gears 29 and the second bevel gears 30. The third bevel gears 31 and the fourth bevel gears 32 are respectively fixedly sleeved on the bidirectional lead screw 12 and the drive screw 22. Multiple bevel gears cooperate with each other to transmit the rotation of the bidirectional lead screw 12 to the drive screw 22, realizing the coordinated operation of the synchronous drive mechanism and the biaxial drive mechanism.

[0026] Two symmetrically arranged L-shaped plates 33 are fixedly arranged on the top of the placement plate 2. A positioning screw 34 is threadedly penetrated through the top of the L-shaped plate 33. A positioning plate 35 is rotatably sleeved at the bottom of the positioning screw 34. A rotating block 36 is fixedly arranged at the top of the positioning screw 34. By rotating the rotating block 36, the height of the positioning plate 35 can be adjusted to adapt to automobile seats of different sizes, realizing the stable fixation of the seats.

[0027] When the automobile seat in-out durability test device of the present invention is in use, first place the automobile seat to be tested on the placing plate 2. According to the size of the seat, rotate the rotating block 36 so that the positioning screw 34 drives the positioning plate 35 to move up and down to firmly fix the seat. Then, start the motor 13. The motor 13 drives the bidirectional lead screw 12 to rotate. Since the two connecting plates 3 are threadedly sleeved on the bidirectional lead screw 12, and the sliding plate 15 and the strip-shaped hole 14 at the top of the test frame 1 limit the connecting plate 3 to only move horizontally, the two connecting plates 3 will drive the fixing plate 4 and the side pressing block 5 to approach the side of the seat synchronously. During this process, according to the actual test requirements, adjust the current magnitudes of the first electromagnetic block 16 and the second electromagnetic block 17 to change the magnetic force between them. Because the magnetic poles of the adjacent sides of the first electromagnetic block 16 and the second electromagnetic block 17 are opposite, the change in the magnetic force will cause the side pressing block 5 to apply different magnitudes of pressure to the side of the seat under the action of the guiding block 19 and the pushing spring 20, simulating the in-out contact actions with different forces to conduct the friction durability test on the side of the seat. At the same time, when the motor 13 drives the bidirectional lead screw 12 to rotate, the third bevel gear 31 on the bidirectional lead screw 12 rotates, drives the transmission rod 28 to rotate through the first bevel gear 29 on the transmission rod 28, and further enables the second bevel gear 30 at the other end of the transmission rod 28 to drive the driving screw 22 to rotate. The different threads at both ends of the driving screw 22 respectively cause the internal thread tube 23 and the pushing block 25 to move. The internal thread tube 23 drives the vertical plate 8 to move horizontally, and the back pressing block 11 on the vertical plate 8 applies pressure to the back of the seat. While the pushing block 25 moves simultaneously, through the cooperation with the inclined surface of the moving block 26, it overcomes the elastic force of the return spring 27 and pushes the vertical rod 9 to move downward. The bottom pressing block 10 at the bottom of the vertical rod 9 applies pressure to the bottom of the seat, realizing the extrusion durability test on the bottom and the back of the seat, thereby completing the simultaneous durability test on multiple parts of the seat and improving the comprehensiveness of the test. After the test is completed, return each component to its original position and take out the seat from the placing plate 2.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
