[0024] See Figure 1 and Figure 2 In this application, the seat 2 to be tested is placed on the device base 1, the left and right positions of the seat 2 are limited by the limiting component, the upper end of the seat 2 is tested by the pressing component, and the bending times of the backrest of the seat 2 are tested by the testing component.

[0025] In the present application, the pressing assembly realizes the up and down movement of the pressing plate 32 by the extension and retraction of the telescopic rod 31, and presses the seat surface of the seat 2 when it moves to the lower end.

[0026] See Figure 3 , 4and 7, in order to test the backrest of the seat 2; the test assembly includes an arc hole block 3 and a connecting block 4, the lower part of the inner surface of the arc hole block 3 is fixedly connected with an arc gear ring 6, the upper middle part of the right end of the connecting block 4 is fixedly connected with a first servo motor 7, the output end of the first servo motor 7 is fixedly connected with a first rotating rod 9 through a coupling 8, the outer surface of the first rotating rod 9 is fixedly connected with a first gear 10, the first gear 10 is meshed with the arc gear ring 6, the lower end of the arc hole block 3 is fixedly connected to the right side of the rear upper end of the device base 1, and the second arc opening groove 15 is coaxial with the rotation axis of the seat 2. The inner surface of the connecting block 4 is symmetrically slidably connected with rectangular rods 11, and the left ends of the two rectangular rods 11 are fixedly connected with rectangular plates 12. A second arc-shaped opening groove 15 is opened at the right end of the arc-shaped hole block 3, and a round rod 17 is fixedly connected to the lower left end of the connecting block 4 symmetrically front and back. The outer surfaces of the two round rods 17 are rotatably connected to rollers 16, and the outer surfaces of the two rollers 16 are rotatably connected to the inner surface of the second arc-shaped opening groove 15.

[0027] See Figure 4 A threaded hole 13 is provided at the rear end of the rear rectangular rod 11 and is connected to the front end of the rectangular rod 11. A threaded rod 12 is threadedly connected to the inner surface of the threaded hole 13. The front end of the threaded rod 12 is rotatably connected to the rear end of the rectangular rod 11 at the front.

[0028] From the above, it can be seen that after the seat 2 backrest is placed between the two rectangular plates 12, the threaded rod 14 is rotated on the inner wall of the threaded hole 13, so that the threaded rod 14 drives the two rectangular plates 12 to move closer to the middle, so that the rectangular plate 510 can fix the seat 2 backrest of different thicknesses, thereby facilitating the bending test of the seat 2 backrest.

[0029] See Figure 5 and Figure 6 The present application provides a limiting component for limiting the position of the seat 2 on the device base 1, so as to achieve the purpose of limiting the position of seats 4 of different sizes.

[0033] The second servo motor 19 mentioned above is controlled by a servo control system in the prior art in this solution, which can control the speed, number of rotations, and rotation angle of the second servo motor 19. In this application, it is only necessary to stop the second servo motor 19 in time after completing the number of rotations and keep the limit plate 25 in a clamped state until the second servo motor 19 is started again.

At this time, the first servo motor 7 is started, so that the output end of the first servo motor 7 drives the first rotating rod 9 to rotate, and then drives the first gear 10 to rotate. Under the action of the meshing connection, the first gear 10 rotates on the arc-shaped gear ring 6, and then drives the connecting block 4 to move, so that the roller 16 on the round rod 17 rotates on the inner wall of the second arc-shaped opening groove 15, thereby driving the backrest of the seat 2 to move downward.

[0040] Secondly, when it bends to the bottom, the first servo motor 7 is started to drive the first rotating rod 9 to reverse, so that the first gear 10 reverses, and then drives the roller 16 on the connecting block 4 to rotate upward on the inner surface of the second arc-shaped opening groove 15, and then drives the rectangular plate 12 to move in the opposite direction, so that the backrest of the seat 2 moves upward.

[0041] The working principle of the car seat reliability test device is as follows:

[0042] First, when in use, the seat 2 to be tested is placed on the device base 1, and the second servo motor 19 is started at this time to drive the second gear 21 on the second rotating rod 20 to rotate, thereby driving the first rack 22 and the second rack 23 to move closer to each other, so that the limiting plates 25 move closer to each other and limit the left and right ends of the seat 2. At this time, the threaded rod 14 is rotated so that the threaded rod 14 drives the two rectangular plates 11 to move closer to each other and fix the backrest of the seat 2. At this time, the first servo motor 7 is started so that the first servo motor 7 drives the first gear 10 on the first rotating rod 9 to rotate on the arc-shaped gear ring 6, and then drives the roller 16 on the connecting block 4 to rotate on the inner wall of the second arc-shaped opening groove 15, so that the rectangular plate 12 after the backrest of the seat 2 is limited and fixed moves, and then the backrest of the seat 2 is subjected to a bending test.

[0043] Compared with traditional testing devices, this application has the following advantages:

[0044] In the present application, during the rotation of the first gear 10, the arc-shaped toothed ring 6 on the inner wall of the arc-shaped hole block 3 is meshed and connected, thereby driving the connecting block 4 to move in an arc, and then driving the rectangular plate 12 on the connecting block 4 to move, so that the rectangular plate 12 can drive the backrest of the seat 3 to bend and rotate, thereby performing a bending test on the backrest of the seat 2.
