[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, a nickel-metal hydride battery testing device includes a testing mechanism body 1. The testing mechanism body 1 can test multiple key electrical performance indicators of nickel-metal hydride batteries. Mounting holes are provided on both sides of the surface of the testing mechanism body 1 to facilitate fixing of the testing mechanism body 1, thereby enabling the device to be used normally.

[0017] A fixed plate 2 is provided at the bottom of the surface of the testing mechanism body 1. Several negative terminals for battery testing are provided on the surface of the fixed plate 2. A movable plate 3 is slidably connected to the top of the surface of the testing mechanism body 1. Several positive terminals for battery testing are provided at the bottom of the movable plate 3. Through the cooperation of the fixed plate 2 and the movable plate 3, the battery can be tested.

[0018] Several connecting shells 4 are fixedly connected to the surface of the fixing plate 2. The connecting shells 4 are used in conjunction with the negative terminal of the battery detection. Under this function, it is convenient to install the subsequent clamping structure in the inner cavity of the connecting shell 4, thereby fixing the battery.

[0019] The inner wall of the connecting shell 4 is provided with a compression mechanism 5. There are two compression mechanisms 5, which are symmetrical with the center line of the connecting shell 4. By setting two compression mechanisms 5, the battery can be clamped more stably, which improves the stability of the battery during testing.

[0020] The compression mechanism 5 includes a guide rod 51 that is slidably connected to the inner wall of the connecting shell 4. One end of the guide rod 51 is fixedly connected to a clamping plate 53, and one side of the clamping plate 53 is fixedly connected to a spring 52. One end of the spring 52 is fixedly connected to the inner wall of the connecting shell 4. With the above structure, batteries of different diameters can be clamped, which effectively improves the flexibility of the compression mechanism 5.

[0021] The guide rod 51 has a T-shaped cross-sectional design. The special shape of the guide rod 51 prevents it from falling off the inner wall of the connecting shell 4, thus providing a stable guarantee for the normal use of the compression mechanism 5.

[0022] The guide rod 51 is located inside the spring 52. The guide rod 51 works in conjunction with the spring 52. Under this action, it can guide the spring 52 during compression or rebound, reducing the possibility of large positional displacement of the spring 52.

[0023] The clamping plate 53 has an arc-shaped structure and is made of rubber. The special shape and material of the clamping plate 53 enable it to fit better with the battery surface, increase the protection of the battery and the anti-slip performance during clamping, so that the battery always stays in a fixed position during the testing process, effectively improving the accuracy of the test.

[0024] The inner cavity of the testing mechanism body 1 is provided with a mounting groove 6, and the inner wall of the mounting groove 6 is provided with a moving mechanism 7. Under this action, the position of the moving plate 3 can be changed by operating the moving mechanism 7. Through the cooperation of the moving mechanism 7 and the compression mechanism 5, it can adapt to batteries of different sizes and specifications, effectively improving the adaptability of the testing mechanism body 1.

[0025] The moving mechanism 7 includes a threaded rod 71 rotatably connected to the inner wall of the detection mechanism body 1. A knob 72 is fixedly connected to the top of the threaded rod 71, which is convenient for the operator to rotate. A sleeve 73 is threadedly connected to the surface of the threaded rod 71. The two sides of the sleeve 73 are slidably connected to the inner wall of the mounting groove 6. The surface of the sleeve 73 is fixedly connected to one side of the moving plate 3.

[0026] The position of the movable plate 3 can be adjusted by rotating the threaded rod 71, so that the positive terminal of the battery test can contact the top of the battery to test multiple key electrical performance indicators of the battery.

[0027] Two sliding blocks 9 are fixedly connected to the surface of the detection mechanism body 1 and are evenly distributed on both sides of the surface of the detection mechanism body 1. The inner wall of the moving plate 3 is provided with a sliding groove 10, and the surface of the sliding block 9 is slidably connected to the inner wall of the sliding groove 10.

[0028] With the cooperation of the sliding block 9 and the sliding groove 10, the moving plate 3 can be guided when it moves, thereby making the moving plate 3 more stable when it moves.

[0029] The bottom of the threaded rod 71 is rotatably connected to a bearing seat 8. The bottom of the bearing seat 8 is fixedly connected to the inner wall of the mounting groove 6. Through the cooperation between the threaded rod 71 and the bearing seat 8, the threaded rod 71 can be made more stable when rotating, reducing the possibility that the threaded rod 71 is not stable enough when rotating and thus affecting the threaded connection with the sleeve 73.

[0030] The testing mechanism body 1 has scale lines 11 on both sides of its surface, and indicator blocks 12 are fixedly connected to both sides of the moving plate 3. The cross-sectional shape of the indicator blocks 12 is a triangular structure design. The indicator blocks 12 work together with the scale lines 11. Under this function, the operator can know the position of the moving plate 3 by the indication of the scale lines 11, and can easily make precise adjustments to the position of the moving plate 3 so that it can stably contact the top of the battery, thereby improving the ease of operation and testing efficiency of the moving plate 3 during use.

[0031] It is worth noting that the technical features such as the detection mechanism body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0032] Working principle: First, when the operator needs to place the battery into the inner cavity of the connecting shell 4 for testing, the clamping plate 53 is pushed to one side. At this time, the clamping plate 53 will drive the guide rod 51 to compress the spring 52, making it easier for the operator to place the battery into the inner cavity of the connecting shell 4. After placement, the spring 52 will push the clamping plate 53 to clamp the battery, thereby fixing the battery and effectively reducing the error caused by shaking and displacement of the battery during the testing process, thus improving the accuracy and stability of the test.

[0033] Subsequently, rotating the knob 72 causes the threaded rod 71 to move the sleeve 73 downward, allowing the positive electrode at the bottom of the moving plate 3 to contact the top of the battery, thereby testing the battery. With the cooperation of the moving mechanism 7 and the compression mechanism 5, the testing mechanism body 1 can test batteries of different sizes and specifications, thereby effectively improving production efficiency and reducing the burden on enterprises that need to equip themselves with multiple testing devices to deal with batteries of different sizes.
