Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 7 This utility model provides a technical solution: a test fixture for ABS control board pins, including a base box 1, a test platform 2 fixedly connected to the top of the base box 1, a fixing frame 3 fixedly connected to the top of the test platform 2, two symmetrically arranged uprights 4 fixedly connected to the upper side of the test platform 2, a lower pressure plate 5 slidably engaged on the two uprights 4, a fixture plate 6 located below and corresponding to the lower pressure plate 5 is arranged above the test platform 2, a fixing component 7 is arranged between the fixture plate 6, the lower pressure plate 5 and the uprights 4, a control board placement slot 8 is opened on the upper side of the fixture plate 6, and a test button 9 is arranged on the front side of the base box 1.

[0025] In this embodiment, a test pin 10 located below the fixture plate 6 is fixedly connected to the upper side of the test platform 2. A through hole 11 corresponding to the test pin 10 is opened downwards through the bottom wall of the control plate placement groove 8. Multiple pressure posts 12 are provided on the lower pressure plate 5. Two sliding holes 13 are opened downwards through the upper side of the lower pressure plate 5 to slide with the two side uprights 4. Two grooves 14 are opened on the side of the fixture plate 6 to slide with the two side uprights 4. Two connecting posts 15 are fixedly connected to the bottom of the fixture plate 6. Two connecting grooves 16 are opened on the upper side of the test platform 2 to slide with the two connecting posts 15. The bottom end of the connecting post 15 connects to the connecting groove. A first spring 17 is fixedly connected between the bottom walls of the 16. A fixing block 18 is fixedly installed on the side of the top plate of the fixing frame 3. A fixing cylinder 19 is fixedly connected to one side of the fixing block 18. A connecting rod 20 that slides in the fixing cylinder 19 is fixedly connected to the upper side of the lower pressure plate 5. A connecting block 21 is fixedly installed on the upper side of the top plate of the fixing frame 3. An L-shaped operating handle 22 is rotatably fitted on one side of the connecting block 21. The right angle of the L-shaped operating handle 22 is hollow and a connecting shaft 23 is fixedly connected between the inner walls of the two sides. A connecting frame 24 is rotatably fitted on the connecting shaft 23. One end of the connecting frame 24 is rotatably fitted with the top end of the connecting rod 20.

[0026] Specifically, by rotating the L-shaped operating handle 22, the L-shaped operating handle 22 rotates around the connecting block 21, which drives the connecting frame 24 to rotate through the connecting shaft 23. The connecting frame 24 pulls the connecting rod 20, causing the lower pressure plate 5 to slide down along the upright 4. The pressure column 12 on the lower pressure plate 5 further presses the control board to ensure that the control board is stable. At the same time, the control board pins make precise contact with the test pins 10 on the test bench 2 through the through hole 11 on the bottom wall of the control board placement slot 8, completing the pin electrical connection.

[0027] In this embodiment, the fixing component 7 includes an inclined positioning block 701 disposed in the control plate placement slot 8. The inner wall of the control plate placement slot 8 has a limiting groove 702 that slides with the inclined positioning block 701. The inner wall of the limiting groove 702 has a displacement groove 703. The bottom of the inclined positioning block 701 is fixedly connected to a displacement block 704 that slides with the displacement groove 703. A second spring 705 is fixedly connected between one side of the displacement block 704 and the inner wall of the displacement groove 703. The inclined side of the inclined positioning block 701 is located on the upper side, and a fixing point located below its inclined side is formed on the front side of the inclined positioning block 701. The upright 4 has a slot 707 inside the slot 706. A displacement strip 708 is slidably fitted on the inner wall of the slot 707. An abutment block 709 is fixedly connected to the bottom side of the displacement strip 708, extending to the outside of the slot 707. The abutment block 709 cooperates with the limiting slot 702 and the inclined positioning block 701. A third spring 710 is fixedly connected between one side of the displacement strip 708 and the inner wall of the slot 707. A locking block 712 is fixedly connected to the top side of the displacement strip 708, extending to the outside of the slot 707. The inner wall of the sliding hole 13 has a locking groove 711 that cooperates with the locking block 712.

[0028] Specifically, when placing the control board, it is placed in the control board placement slot 8 of the fixture plate 6. The control board presses against the inclined positioning block 701. The inclined positioning block 701 overcomes the elastic force of the second spring 705 and slides down along the limiting slot 702 and the displacement slot 703. After the control board is placed, the inclined positioning block 701 resets under the action of the second spring 705, and its positioning slot 706 locks the control board, achieving initial positioning. At the same time, the inclined positioning block 701 abuts against the abutment block 709 below the displacement bar 708, pushing the displacement bar 708 into the empty slot 707. This causes the locking blocks 712 and abutment blocks 709 on both sides of the displacement bar 708 to move away from the locking slot 711 and the limiting slot 702, releasing the fixed limitation between the fixture plate 6 and the lower pressure plate 5 and the upright 4, creating conditions for the lower pressure plate 5 to press down.

[0029] When using the device, first place the ABS control board in the control board placement slot 8 of the fixture plate 6. During placement, the control board presses the inclined positioning block 701, causing it to overcome the elastic force of the second spring 705 and slide down along the limiting slot 702 and the displacement slot 703. After placement, the inclined positioning block 701 resets under the action of the second spring 705, and its positioning slot 706 locks the control board to achieve initial positioning. At this time, the inclined positioning block 701 abuts against the abutting block 709 below the displacement bar 708, causing the displacement bar 708 to retract into the empty slot 707. At this time, the locking blocks 712 and abutting blocks 709 on the upper and lower sides of the displacement bar 708 move away from the locking slot 711 and the limiting slot 702, thereby releasing the fixed limit between the fixture plate 6 and the lower pressure plate 5 and the upright 4. Next, rotate the L-shaped operating handle 22. The L-shaped operating handle 22 rotates around the connecting block 21, which drives the connecting frame 24 to rotate through the connecting shaft 23. The connecting frame 24 pulls the connecting rod 20, causing the lower pressure plate 5 to move downward along the upright 4. Sliding, the pressure column 12 on the lower pressure plate 5 presses the control board tightly, and at the same time, the control board pins contact the test needles 10 on the test bench 2 through the through hole 11 on the bottom wall of the control board placement slot 8 to complete the pin connection; when the control board placement slot 8 of the fixture plate 6 is not placed, the displacement bar 708, through the force of the third spring 710, makes the locking blocks 712 and the abutment blocks 709 on its upper and lower sides located in the locking slots 711 and the limiting slots 702, positioning the fixture plate 6 and the lower pressure plate 5 on the upright 4 for fixed limiting, reducing the possibility that the moving fixture plate 6 and the lower pressure plate 5 may expose the test needles 10 and cause damage when not in use; by pressing the test button 9 on the front side of the bottom box 1, the test system tests the pins of the ABS control board through the test needles 10, obtains test data and determines whether the control board pins are normal. After the test is completed, rotate the L-shaped operating handle 22 again to move the lower pressure plate 5 upward and reset, remove the control board, and prepare for the next test.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
