Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 - 5 , the present invention provides a test bench for automotive air conditioning products, including a bench body 1. A limiting mechanism 2 is provided at the top of the bench body 1. A support platform 3 is fixedly provided in the middle of the top of the bench body 1. First electric push rods 4 are fixedly provided on both sides of the top of the bench body 1. The telescopic ends of the first electric push rods 4 are fixedly connected to a lifting plate 5. An adjusting rail 7 is fixedly provided between the two lifting plates 5. A moving seat 8 is slidably connected inside the adjusting rail 7. A linkage plate 11 is fixedly connected to the middle of the top of the moving seat 8. A second electric push rod 9 is fixedly provided on one side of the linkage plate 11. The telescopic end of the second electric push rod 9 is fixedly connected to a connecting seat 10. A plug 6 is fixedly provided at the top of the connecting seat 10. The first electric push rod 4 drives the plug 6 to move up and down, and the moving seat 8 drives the linkage plate 11 and the connecting seat 10 to move, thereby driving the plug 6 to move left and right. The second electric push rod 9 can push the plug 6 towards the joint position of the automotive air conditioning product to achieve automatic power plugging;

[0025] The connecting lead screw 12 is rotatably connected inside the adjusting rail 7 through a bearing. The outer wall of the connecting lead screw 12 is threadedly connected to the inside of the moving seat 8. A driving motor 13 is fixedly provided on one side of the top of one of the lifting plates 5. One end of the connecting lead screw 12 penetrates through one side of the adjusting rail 7 and is fixedly connected to the transmission shaft of the driving motor 13. The driving motor 13 provides power for the connecting lead screw 12. Under the threaded cooperation of the connecting lead screw 12 and the moving seat 8, the moving seat 8 moves linearly, and further drives the plug 6 to move left and right;

[0026] On both sides of the top end of the connecting seat 10, fixing plates 14 are fixedly connected. In the middle of one side of the fixing plate 14, a screw rod 15 is threadedly connected. On both sides of the plug 6, screw holes 16 are opened. One end of the screw rod 15 penetrates through the fixing plate 14 and is threadedly connected with the screw hole 16. Turning the screw rod 15 out of the screw hole 16 to release the plug 6 from the limit, the plug 6 can be removed, and thus the damaged plug 6 can be replaced in time;

[0027] On one side of the top end of the support platform 3, a sliding groove 17 is opened. At the bottom end of the adjusting rail 7, a sliding plate 18 fixedly connected with the sliding groove 17 is connected. The sliding plate 18 moves in the sliding groove 17 to limit the position of the up-and-down movement of the adjusting rail 7, so that the adjusting rail 7 can move vertically;

[0028] Specifically, first start the driving motor 13 to make the connecting screw rod 12 rotate. Under the threaded cooperation of the connecting screw rod 12 and the moving seat 8, the moving seat 8 moves linearly, driving the connecting seat 10 and the plug 6 to move left and right. Then adjust the first electric push rod 4 to drive the lifting plate 5 and the adjusting rail 7 to move linearly, so that the plug 6 moves up and down. Through the driving motor 13 and the first electric push rod 4, the plug 6 can be aligned with the joint position of the automotive air-conditioning product. Finally, adjust the second electric push rod 9 to insert the plug 6 into the joint position, so that the automotive air-conditioning product can be automatically powered on.

[0029] Embodiment 2:

[0030] The limiting mechanism 2 includes a support frame 201, and the support frame 201 is fixedly arranged at the top end of the bench body 1. At the top of the support frame 201, two guide rods 202 are fixedly connected. Between the two guide rods 202, two guide plates 203 are slidably connected. At the bottom end of the guide plate 203, a limiting plate 204 is fixedly connected. On one side of the limiting plate 204, a protective pad 205 is fixedly arranged. The guide rods 202 limit the moving position of the guide plate 203 to make the guide plate 203 move linearly. Under the movement of the two limiting plates 204, the automotive air-conditioning product is positioned in the middle of the support platform 3, and dry ice limits the automotive air-conditioning product;

[0031] In the middle of the inner wall of the top end of the support frame 201, a connecting plate 206 is connected. At the bottom end of the connecting plate 206, a rotating plate 207 is rotatably connected. On both sides of the bottom end of the rotating plate 207, first rotating seats 208 are fixedly connected. At the top of one side of the limiting plate 204, a second rotating seat 209 is fixedly connected. Between the first rotating seat 208 and the second rotating seat 209, a connecting rod 210 is rotatably connected. The rotating plate 207 rotates to change the positions of the two first rotating seats 208, and thus the connecting rod 210 rotates. During the rotation of the connecting rod 210, the two limiting plates 204 can be driven to move towards the middle at the same time;

[0032] The middle part of the top end of the rotating plate 207 is fixedly connected with a rotating shaft 211. The top end of the rotating shaft 211 is rotationally connected to the middle part of the bottom end of the connecting plate 206 through a bearing. The rotating shaft 211 limits the rotation direction of the rotating plate 207, and further limits the positions where the two first rotating seats 208 move;

[0033] The middle part of one side of the connecting plate 206 is fixedly provided with a third electric push rod 212. The telescopic end of the third electric push rod 212 is fixedly connected to the middle part of one side of one of the guide plates 203. The third electric push rod 212 drives one of the guide plates 203 to move, so that one of the limiting plates 204 pulls one of the connecting rods 210 to rotate, and the other connecting rod 210 can be driven to rotate through the rotating plate 207;

[0034] Specifically, first adjust the third electric push rod 212 to make the third electric push rod 212 shorten, drive one of the guide plates 203 and one of the limiting plates 204 to move towards the middle, push one of the connecting rods 210 to rotate, and then push the rotating plate 207 to rotate. The other connecting rod 210 is driven to rotate through the rotating plate 207, and then the other limiting plate 204 is pulled towards the middle. Under the movement of the two limiting plates 204, the automotive air-conditioning product is limited to facilitate testing.

[0035] When in use, first place the automotive air-conditioning product on the top end of the support table 3, and then adjust the third electric push rod 212 to make the third electric push rod 212 shorten, drive one of the guide plates 203 and one of the limiting plates 204 to move towards the middle, push one of the connecting rods 210 to rotate, and then push the rotating plate 207 to rotate. The other connecting rod 210 is driven to rotate through the rotating plate 207, and then the other limiting plate 204 is pulled towards the middle. Under the movement of the two limiting plates 204, the automotive air-conditioning product is limited to facilitate testing;

[0036] Then start the drive motor 13 to make the connecting lead screw 12 rotate. Under the screw-thread fit between the connecting lead screw 12 and the moving seat 8, the moving seat 8 moves linearly, driving the connecting seat 10 and the plug 6 to move left and right. Then adjust the first electric push rod 4 to drive the lifting plate 5 and the adjusting rail 7 to move linearly, so that the plug 6 moves up and down. Through the drive motor 13 and the first electric push rod 4, the plug 6 can be aligned with the joint position of the automotive air-conditioning product. Finally, adjust the second electric push rod 9 to push the plug 6 and insert the plug 6 into the joint position, so that the automotive air-conditioning product can be automatically powered on according to the joint position of the automotive air-conditioning product.

[0037] 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 principle and spirit of the present invention.
