[0006] By adopting the above technical solution, when the seat needs to be tested, the seat is abutted against the seat through the seat fixing part, and then the seat is moved forward and backward through the forward and backward moving component through the seat fixing part for testing, and then the seat is driven to be lifted and moved through the seat fixing part through the lifting and moving component, thereby realizing the test process of the seat, thereby reducing the need for manual inspection of the seat, resulting in low seat inspection efficiency.

[0007] Optionally, the forward and backward moving component includes a first slider, the first slider is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to a first gear, and a first rack is meshed on one side of the first gear.

[0008] By adopting the above technical solution, when the seat needs to be moved forward or backward, the first motor is turned on. During the startup process, the first motor drives the first gear to rotate. During the rotation process, the first gear engages with the first rack to drive the first motor and the first slider to move. During the movement of the first slider, the seat is driven to move through the seat fixing part.

[0009] Optionally, the first sliding block is penetrated by and slidably connected with a plurality of first sliding rail rods arranged parallel to each other, and the first sliding rail rods are arranged parallel to the first rack.

A first motor 33 is fixedly connected to the upper side of the first slider 31, and a first gear 34 is fixedly connected to the output shaft of the first motor 33. A first rack 35 is meshed with the lower side of the first gear 34, and the first rack 35 is arranged parallel to the first slide rail 32.

[0034] When the seat fixing part 5 needs to be moved, the first motor 33 is turned on, and the output shaft of the first motor 33 drives the connected first gear 34 to rotate during the rotation process. The first gear 34 drives the first gear 34 and the first motor 33 to move by meshing with the first rack 35 during the rotation process, and the first motor 33 drives the first slider 31 and the seat fixing part 5 to move during the movement process, thereby realizing the process of driving the seat 2 to move through the seat fixing part 5.

[0035] The lifting and moving assembly 4 includes a second motor 41 fixedly connected to the upper side of the first slider 31, the output shaft of the second motor 41 is fixedly connected to the second gear 42, one side of the second gear 42 is meshed with a second rack 43, the second rack 43 is vertically arranged and slidably connected to the first slider 31 in the vertical direction. The second rack 43 is arranged in an L shape, and the short side of the L shape at the bottom of the second rack 43 is arranged horizontally. The short side of the L shape of the second rack 43 is connected to the seat fixing member 5.

[0036] When the seat 2 needs to be driven to move up and down, the second motor 41 is turned on, and the output shaft of the second motor 41 drives the second gear 42 to rotate during the rotation process. The second gear 42 is engaged with the second rack 43 during the rotation process, thereby driving the second rack 43 to move up and down. The second rack 43 drives the seat 2 to move up and down through the seat fixing member 5 during the up and down movement process, thereby realizing the test of the lifting function of the seat 2.

[0037] The seat fixing member 5 includes a base 51 located on the upper side of the seat surface, and the base 51 is arranged horizontally. A vertically arranged vertical square rod 52 is fixedly connected to the upper side of the base 51, and the vertical square rod 52 passes through the L-shaped short side wall of the second rack 43 in the vertical direction and is slidably connected to the second rack 43 in the horizontal direction, and the vertical square rod 52 is clamped with the second rack 43 in the vertical direction.

[0038] When the first motor 33 drives the first slider 31 to move horizontally, the first slider 31 drives the base 51 to move horizontally through the vertical square rod 52 and the vertical sliding rod 53, and the base 51 abuts against the seat surface to drive the seat 2 to move horizontally. When the second motor 41 drives the second rack 43 to move up and down, the second rack 43 drives the base 51 to move up and down through the vertical square rod 52, thereby realizing the process of lifting and lowering the seat 2.

[0039] A front-to-back adjustment handle 21 is connected to one side of the seat 2, and the front-to-back adjustment handle 21 is used to lock and unlock the locking state of the front-to-back movement of the seat 2. A height adjustment handle 22 is provided on one side of the position where the front-to-back adjustment handle 21 is connected to the seat 2, and the height adjustment handle 22 is used to lock and unlock the lifting and moving state of the seat 2. When the height adjustment handle 22 is turned to unlock the lifting state of the seat 2, the seat 2 automatically moves upward.

[0040] A locking assembly 6 is connected to one side of the first slider 31, and the locking assembly 6 is used to connect with the front and rear adjustment handle 21 and the height adjustment handle 22, and drive the front and rear adjustment handle 21 and the height adjustment handle 22 to rotate, thereby realizing the opening and locking of the front and rear movement state or the lifting and lowering movement state of the seat 2.

[0045] When testing the forward and backward movement function of the seat 2, the handle groove 63 is sleeved on the outside of the forward and backward adjustment handle 21. Then, the first motor 33 is turned on to drive the first slider 31 to move. Under the constraint of the V-shaped slide groove 611, the first slider 31 drives the slide bar 621 and the handle adjustment rod 62 to move upward in the process of driving the connecting plate 61 to move, so that the handle groove 63 drives the forward and backward adjustment handle 21 to rotate and enables the seat 2 to move forward and backward. After that, the first motor 33 continues to drive the first slider 31 to move. During the movement, the first slider 31 abuts against the second slider 54 and drives the vertical square rod 52 and the vertical sliding rod 53 to move horizontally. Then, the vertical square rod 52 and the vertical sliding rod 53 drive the base 51 to move, and the seat 2 is driven to move during the movement of the base 51. In this way, the test process of the forward and backward movement function of the seat 2 is realized.

[0046] When the lifting function of the seat 2 needs to be tested, the handle groove 63 is set on the outside of the height adjustment handle 22, and the second slider 54 is located in the middle of the first slider 31.

Then the second motor 41 is turned on to drive the second rack 43 and the base 51 to move downward to press the seat 2.

[0047] After the pressing is completed, the first motor 33 is turned on to drive the first slider 31 to move in the opposite direction, so that the handle adjustment rod 62 moves downward under the constraint of the V-shaped slide groove 611, thereby realizing the locking state of the lifting and lowering movement of the seat 2. After that, the first motor 33 continues to move, thereby driving the height adjustment handle 22 to rotate through the handle groove 63, starting the lifting and lowering movement state of the seat 2, and the seat 2 returns to the initial position, thereby realizing the test of the lifting and lowering function of the seat 2.

[0048] The implementation principle of an aviation seat durability testing device according to an embodiment of the present application is as follows: when the seat 2 needs to be tested for forward and backward movement, the base 51 is brought into contact with the seat surface, and then the first motor 33 is turned on, so that the first motor 33 drives the base 51 and the seat 2 to move forward and backward, thereby realizing the test of the forward and backward movement function of the seat 2.

[0049] When the seat 2 needs to be tested for lifting and moving, the first motor 33 is first turned on to start the lifting and moving function of the seat 2, and then the seat 2 is driven to move downward by the second motor 41. Then, the first motor 33 and the second motor 41 are turned on at the same time to move the seat 2 upward, thereby realizing the test process of the lifting and moving function of the seat 2.
