[0023] Please see Figure 1-3 A lithium battery protection board test rack includes a base box 1, several test boards 2, a vertical wall 3, a slide 4, a pressure plate 5, a pressing assembly 6, a sliding plate 7, and a push-pull assembly 8. Several test boards 2 are mounted on the top surface of the base box 1. Each test board 2 has a receiving groove 21 on its top surface for placing the battery protection board. The vertical wall 3 is erected on one edge of the top surface of the base box 1. The slide 4 is movably mounted on the upper side of the vertical wall 3. The pressure plate 5 is vertically mounted below the slide 4, above the test boards 2. Several probes 9 are provided on the bottom surface of the pressure plate 5 for testing the battery protection board. The pressing assembly 6 is connected to the pressure plate 5 and drives the pressure plate 5 to move up and down. The sliding plate 7 is horizontally movably mounted on the bottom surface of the base box 1, located on one side of the test boards 2. Several test connectors 10 are provided on the side of the sliding plate 7 facing the test boards 2. One end of the push-pull assembly 8 is connected to the sliding plate 7 and drives the sliding plate 7 to move horizontally relative to the test boards 2. In this embodiment, the direction of horizontal movement of the slide 4 is perpendicular to the direction of horizontal movement of the sliding plate 7.

[0024] Three test boards 2 and three test connectors 10 are provided in this invention, but the number of test boards 2 and test connectors 10 is not limited in this invention. The number of test boards 2 can also be set to other natural integers according to actual conditions. During testing, the battery protection board is first placed in the receiving groove 21 of the test board 2. Then, the pressing component 6 drives the pressure plate 5 to move down towards the test board 2 until the probe 9 on the bottom surface of the pressure plate 5 contacts the test point of the battery protection board in the receiving groove 21. At the same time, the sliding plate 7 can be driven to move towards the test board 2 by the pushing and pulling component 8 until the test connector 10 on the sliding plate 7 connects with the connector of the battery protection board, thereby testing the electrical performance of the battery protection board. Compared with traditional manual testing, this invention is simple to operate, can test multiple battery protection boards at one time, has a fast testing speed, saves time and effort, and thus improves testing efficiency.

[0025] Please see Figure 1 The pressing component 6 includes a fixed base 61, a sleeve 62, a slide rod 63, a connecting rod 64, a handle 65, and a buffer structure 66. The fixed base 61 is located on the side of the slide 4 away from the vertical wall 3. The sleeve 62 is connected to the lower side of the fixed base 61. The bottom end of the slide rod 63, which is movably inserted into the sleeve 62, is connected to the pressure plate 5 through the buffer structure 66. The top end of the slide rod 63 is hinged to one end of the connecting rod 64. The end of the connecting rod 64 away from the slide rod 63 is hinged to the bend of the handle 65. One end of the handle 65 is hinged to the upper part of the fixed base 61.

[0026] In this embodiment, the handle 65 is L-shaped, and a hinge portion 611 is formed on the upper side of the fixed base 61. One end of the handle 65 is hinged to the hinge portion 611. All the above-mentioned hinge methods are hinged by a pin. During testing, rotating the handle 65 causes the handle 65 to drive the slide rod 63 to move downward along the axis of the sleeve 62 via the connecting rod 64, thereby driving several probes 9 on the pressure plate 5 downward to facilitate rapid testing.

[0027] Please see Figure 1 The buffer structure 66 includes a hanging plate 661, a mounting rod 662, and a spring 663. The hanging plate 661 is connected to the bottom end of the sliding rod 63. The mounting rods 662 are respectively vertically arranged on both sides of the bottom surface of the hanging plate 661. The pressure plate 5 has a sliding hole 51 and is movably mounted on the mounting rod 662 through the sliding hole 51. The spring 663 is sleeved on the mounting rod 662. One end of the spring 663 is connected upward to the bottom surface of the hanging plate 661, and the other end is connected downward to the top surface of the pressure plate 5. In this embodiment, the spring 663 is a helical spring. During testing, when the probe 9 descends and contacts the test point of the battery protection board, if the downward pressure distance is too large, the pressure plate 5 will compress the spring 663. At this time, the spring 663 provides a buffering effect to prevent the probe 9 from directly damaging the battery protection board.

[0028] The slide block 4 has two opposing guide rods 67 on its bottom surface. The pressure plate 5 is movably mounted on the two guide rods 67. The guide rods 67 guide the movement of the pressure plate 5 so that the pressure plate 5 can rise and fall stably.

[0029] Please see Figure 1 The vertical wall 3 is provided with two parallel first guide rails 11, and the slide 4 is movably mounted on the two first guide rails 11. A horizontal adjustment assembly 12 is provided on the vertical wall 3. The horizontal adjustment assembly 12 includes two bearing seats 121 disposed opposite each other on the side of the vertical wall 3 and a first lead screw 122 rotatably mounted on the two bearing seats 121. A nut sleeve 13 is provided on the side of the slide 4 away from the pressing assembly 6, and the nut sleeve 13 is threaded onto the first lead screw 122. Before testing, if it is found that the probe 9 is not aligned with the test point on the battery protection board, the first lead screw 122 is rotated, and the slide 4 moves horizontally under the drive of the first lead screw 122, thereby aligning the probe 9 with the test point on the battery protection board.

[0030] Please see Figure 3 The pressure plate 5 has several mounting holes 52 for mounting probes 9 at the position corresponding to the test plate 2. By mounting the probes 9 in different mounting holes 52 and adjusting the position of the probes 9 with the horizontal adjustment component 12, it is possible to test battery protection boards of different specifications, which has a wider range of applications and good versatility.

[0031] Please see Figure 1-2 The test plate 2 is provided with clamping components 14 on both sides. The clamping components 14 include a mounting base 141, a second lead screw 142 and a clamping plate 143. The mounting base 141 is fixed to the outside of the test plate 2. A nut (not shown) is installed inside the mounting base 141. The second lead screw 142 passes through the mounting base 141 and is rotatably connected to the nut. The clamping plate 143 is movably disposed in the receiving groove 21. One end of the second lead screw 142 is rotatably connected to the clamping plate 143.

[0032] During testing, after the battery protection board is placed in the receiving groove 21, the second lead screw 142 is rotated. The second lead screw 142 drives the clamping plate 143 to move towards the end of the battery protection board until the clamping plate 143 clamps the end of the battery protection board, preventing the battery protection board from shifting during the test and improving the accuracy of the test results. In this embodiment, guide grooves (not shown) are respectively opened on the two side walls of the receiving groove 21, and the clamping plate 143 has protruding edges (not shown) on both sides that are adapted to the guide grooves. The protruding edges are movably arranged in the guide grooves; through the cooperation of the protruding edges and the guide grooves, the clamping plate 143 moves more stably in the receiving groove 21.

[0033] Please see Figure 2The test board 2 has a clearance groove 22 on the top side wall facing the test connector 10, which communicates with the receiving groove 21. During the test, the test connector 10 passes through the clearance groove 22 and docks with the battery protection board in the receiving groove 21.

[0034] The top surface of the slide plate 7 has a groove for the test connector 10 to be inserted into; the top surface of the base box 1 is provided with two parallel second guide rails 15, the slide plate 7 is movably mounted on the two second guide rails 15, and the bottom surface of the slide plate 7 is provided with a slider that is adapted to the second guide rails 15; in this embodiment, the structure of the push-pull assembly 8 is the same as the structure of the pressing assembly 6, and its structure will not be described in detail here.

[0035] The working principle of this utility model of a lithium battery protection board test rack is as follows: Before testing, according to the specifications of the battery mounting plate, the corresponding probes 9 are installed in the mounting holes 52 at the corresponding positions of the pressure plate 5; after installation, the battery protection board is placed in the receiving groove 21 of the test plate 2, and then the second lead screw 142 is rotated so that the clamping plate 143 is clamped at the end of the battery protection board; the first lead screw 122 is rotated, and the slide 4 moves horizontally under the drive of the first lead screw 122 so that the probes 9 are aligned with the test points of the battery protection board; when the test points are completely aligned, the test is started. The handle 65 is rotated so that the handle 65 drives the slide 63 to move downward along the axis of the sleeve 62 through the connecting rod 64 until several probes 9 on the pressure plate 5 move downward and contact the test points on the battery protection board, thereby realizing the test; when it is necessary to connect and test the test connector 10, the push-pull assembly 8 drives the slide plate 7 to move horizontally relative to the test plate 2 until the test connector 10 is docked with the battery protection board.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
