[0015] (3) Beneficial effects

[0016] The present invention provides a device for automotive FCT function testing, which has the following beneficial effects:

[0017] 1. For the device for automotive FCT function testing, by setting a clamping mechanism, a linkage component and a moving mechanism, the automotive electronic controller to be tested is placed inside the left and right two workstations at the upper end of the placement plate.

As the placement plate moves, the clamping mechanism at the left end can be driven by the cooperation of the linkage component to clamp the automotive electronic controller, while the clamping mechanism at the right end no longer clamps the automotive electronic controller, thus facilitating the removal of the tested automotive electronic controller at the right end, so that manual clamping is no longer required when clamping the automotive electronic controller; moreover, since the two workstations alternate for testing, the testing efficiency can also be improved.

[0018] 2. For the device for automotive FCT function testing, through the second bearing seat, the bidirectional threaded rod, the moving block and the handle, when the handle is rotated, the bidirectional threaded rod can be driven to rotate under the action of the second bearing seat, and then drive the moving block to slide inside the square hole. Since the thread directions inside the two moving blocks are opposite, the two moving blocks can be driven to move relatively or in opposite directions. As the two moving blocks move, the limiting plate can be driven to move on the upper end of the placement plate, so that the distance between the two limiting plates can be changed, so as to facilitate the limitation of both sides of the automotive electronic controller, thus facilitating the worker to place the automotive electronic controller.

Specific embodiments

[0028] 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.

[0029] The present invention provides a technical solution:

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 8 , a device for automotive FCT function testing, including a base plate 1. A moving mechanism 2, a linkage assembly 3 and a placing plate 10 are arranged at the upper end of the base plate 1. There are two sets of linkage assemblies 3, and they are located at the front and rear ends of the placing plate 10; the base plate 1 is connected to the placing plate 10 through the moving mechanism 2. A clamping mechanism 4 is arranged at the upper end of the placing plate 10, and the clamping mechanism 4 is used for clamping an automotive electronic controller; an adjusting mechanism 8 is arranged at the lower end of the placing plate 10, and a limiting plate 5 is arranged at the upper end of the placing plate 10. The placing plate 10 is connected to the limiting plate 5 through the adjusting mechanism 8; a support frame 7 is fixedly connected to the upper end of the base plate 1. Lifting mechanisms 6 are arranged at the upper and lower ends of the support frame 7, and a test head 14 is arranged at the lower end of the support frame 7. The support frame 7 is connected to the test head 14 through the lifting mechanism 6.

[0032] Specifically, the automotive electronic controller to be tested is placed inside the left and right workstations at the upper end of the placement board 10. Since the automotive electronic controller on the right end is located below the test head 14, then the lifting mechanism 6 works. Under the action of the lifting mechanism 6, the test head 14 can be driven to move downward, so that the test head 14 is inserted into the automotive electronic controller, which facilitates the test head 14 to conduct tests. After the automotive electronic controller on the right end is tested, the moving mechanism 2 drives the placement board 10 to move to the right, so that the placement board 10 moves from the leftmost end to the rightmost end. At this time, it is convenient to test the automotive electronic controller on the left end. As the placement board 10 moves, the clamping mechanism 4 on the left end can be driven to clamp the automotive electronic controller under the cooperation of the linkage component 3, while the clamping mechanism 4 on the right end no longer clamps the automotive electronic controller, thus facilitating the removal of the tested automotive electronic controller on the right end, eliminating the need for manual clamping when clamping the automotive electronic controller; and since the two workstations alternately conduct tests, the test efficiency can also be improved.

[0033] Embodiment Two

[0034] Please refer to Figure 1 , a support leg 13 is fixedly connected to the lower end of the bottom plate 1. There are multiple support legs 13, and they are evenly distributed at the lower end of the bottom plate 1. During operation, by setting the support legs 13, the bottom plate 1 can be supported to facilitate the operation of workers.

[0035] Embodiment Three

[0036] Please refer to Figures 1 to 5 , the moving mechanism 2 includes a motor 201, a lead screw 202, a moving seat 203 and a first bearing seat 204. The motor 201 and the first bearing seat 204 are fixedly connected to the upper end of the bottom plate 1. The lead screw 202 is rotatably connected inside the first bearing seat 204. The lead screw 202 is fixedly connected to the output end of the motor 201. The moving seat 203 is threadedly connected to the circumferential surface of the lead screw 202. The upper end of the moving seat 203 is fixedly connected to the placement board 10. During operation, when the motor 201 is turned on, the lead screw 202 can be driven to rotate under the cooperation of the first bearing seat 204, and then the moving seat 203 is driven to move, which facilitates driving the placement board 10 to move.

[0037] Embodiment Four

[0038] Please refer to Figures 1 to 3 , a slider 9 is fixedly connected to the lower end of the placement board 10. A slide rail 11 and a baffle 12 are fixedly connected to the upper end of the bottom plate 1. The baffle 12 is located at both ends of the slide rail 11 and is fixedly connected to the slide rail 11. The slider 9 is slidably connected to the slide rail 11. During operation, by setting the slider 9 and the slide rail 11, the movement of the placement board 10 can be limited at this time, so that the placement board 10 moves smoothly.

[0039] Example 5

[0040] Please refer to Figures 5 to 6 , the adjusting mechanism 8 includes a second bearing seat 801, a bidirectional threaded rod 802, a moving block 803 and a handle 804. The lower end of the placing plate 10 is fixedly connected to the second bearing seat 801. The second bearing seat 801 internally rotatably connects the bidirectional threaded rod 802. One end of the bidirectional threaded rod 802 close to the end of the placing plate 10 is fixedly connected to the handle 804. The circumferential surface of the bidirectional threaded rod 802 is threadedly connected to the moving block 803. The upper end of the moving block 803 is fixedly connected to the limiting plate 5. A square hole 16 is opened on the upper end surface of the placing plate 10. The moving block 803 is located in the square hole 16 and is slidably connected to the square hole 16. During operation, by rotating the handle 804, the bidirectional threaded rod 802 can be driven to rotate under the action of the second bearing seat 801, and then the moving block 803 is driven to slide inside the square hole 16. Since the thread directions inside the two moving blocks 803 are opposite, the two moving blocks 803 can be driven to move relatively or contrarily. As the two moving blocks 803 move, the limiting plate 5 can be driven to move on the upper end of the placing plate 10, so as to change the distance between the two limiting plates 5, facilitating the limitation of both sides of the automotive electronic controller, and thus facilitating the worker to place the automotive electronic controller.

[0041] Example 6

[0042] Please refer to Figures 3 to 8 , the clamping mechanism 4 includes a clamping plate 401, a moving rod 402, a spring 403 and a limiting seat 404.

The retaining ring 15 is located at the end of the limiting seat 404 away from the clamping plate 401. During operation, by moving the clamping plate 401 towards the automotive electronic controller, the automotive electronic controller can be stably fixed inside the limiting plate 5 under the action of the clamping plate 401, facilitating subsequent testing.

[0043] Example 7

[0044] Please refer to Figures 1 to 4, the linkage component 3 includes a support rod 301, a fixed frame 302, a sliding hole 303 and a sliding rod 304. The upper end of the bottom plate 1 is fixedly connected with the support rod 301. One side of the support rod 301 close to the limit seat 404 is fixedly connected with the fixed frame 302. The upper end surface of the fixed frame 302 is provided with the sliding hole 303. The sliding rod 304 is slidably connected inside the sliding hole 303. The sliding rod 304 is fixedly connected with the moving rod 402. During operation, through the movement of the placing plate 10, the sliding rod 304 can be driven to slide inside the sliding hole 303. When the sliding rod 304 is located on the left and right sides of the sliding hole 303, the clamping plate 401 can be driven to move away from the automotive electronic controller, so as to facilitate the worker to take out the automotive electronic controller from the limiting plate 5.

[0045] Embodiment VIII

[0046] Please refer to Figures 1 to 2 , the lifting mechanism 6 includes a cylinder 601, a guide rod 602 and a mounting plate 603. The upper end of the support frame 7 is fixedly connected with the cylinder 601. The extending end of the cylinder 601 penetrates through the lower end of the support frame 7 and is slidably connected between the support frames 7. The extending end of the cylinder 601 is fixedly connected with the mounting plate 603. The lower end of the mounting plate 603 is fixedly connected with the test head 14. The upper end of the mounting plate 603 is fixedly connected with the guide rod 602. The guide rod 602 is slidably connected with the support frame 7. During operation, by starting the cylinder 601, the cylinder 601 extends. At this time, with the cooperation of the guide rod 602, the mounting plate 603 can be driven to move down smoothly. As the mounting plate 603 moves down, the test head 14 is also driven to move down, so as to facilitate the test head 14 to be inserted into the automotive electronic controller to facilitate the testing of the automotive electronic controller.

[0047] Working principle,

[0048] During use, place the automotive electronic controller to be tested inside the left and right workstations at the upper end of the placement plate 10. Since the automotive electronic controller on the right end is located below the test head 14, start the cylinder 601, causing the cylinder 601 to extend. At this time, with the cooperation of the guide rod 602, the mounting plate 603 can be driven to move downward smoothly. As the mounting plate 603 moves downward, the test head 14 is also driven to move downward, facilitating the insertion of the test head 14 into the interior of the automotive electronic controller to facilitate the testing of the automotive electronic controller. After the testing of the automotive electronic controller is completed, the cylinder 601 retracts, driving the test head 14 away from the automotive electronic controller. Then, start the motor 201. At this time, with the cooperation of the first bearing block 204, the lead screw 202 can be driven to rotate, thereby driving the moving seat 203 to move to the right, which facilitates driving the placement plate 10 to move. As the placement plate 10 moves to the right, the left end slide bar 304 enters the middle position of the slide hole 303. During the process of the slide bar 304 entering the middle position of the slide hole 303, it drives the moving rod 402 to slide inside the limit seat 404, and at this time, the clamping plate 401 can be driven to move towards the automotive electronic controller. Under the action of the clamping plate 401, the automotive electronic controller can be stably fixed inside the limiting plate 5, facilitating the testing of the automotive electronic controller at the left end. When the automotive electronic controller at the left end is located below the test head 14, at this time, the slide bar 304 at the right end is located at the right end of the slide hole 303, which can drive the clamping plate 401 away from the automotive electronic controller, thus releasing the fixation of the automotive electronic controller and facilitating the worker to take out the automotive electronic controller from between the limiting plates 5. In this way, manual clamping is not required when clamping the automotive electronic controller, thereby improving the testing efficiency.
