[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A battery pack positioning detection device includes a multimeter 1, a socket 2 is provided on the front of the multimeter 1, and a plug 3 is inserted inside the socket 2. The plug-in principle of the socket 2 and the plug 3 is the existing technology and will not be described in detail here. A connecting wire 15 is connected to the bottom end of the plug 3, and the other end of the connecting wire 15 is connected to the test lead, so that the positioning detection of the battery pack can be realized. The front of the socket 2 is symmetrically covered with a covering plate 4, and a first spring 5 is connected to the side of the covering plate 4 that is away from each other, and the other end of the first spring 5 is connected to a rectangular frame 6, and the side of the rectangular frame 6 is connected to the front of the multimeter 1. Through the cooperation between the covering plate 4 and the first spring 5, the socket 2 can be covered and protected when not in use to effectively prevent the entry of dust and debris.

[0023] Further, see Figure 3 and Figure 4 It can be known that the front side of the covering plate 4 is arranged as an arc structure, and a rubber plate 10 is glued to the front side of the covering plate 4. When in use, the covering plate 4 arranged with an arc structure can automatically drive the two groups of covering plates 4 to move away from each other during the insertion process of the plug 3. In combination with the rubber plate 10 arranged with rubber material, the protection operation of the front end of the test lead can be realized.

[0024] Further, see Figure 3 It can be known that the bottom end of the rectangular frame 6 is connected to a mounting plate 7, and both sides of the mounting plate 7 are connected to the multimeter 1 by bolts. When in use, through the cooperation between the mounting plate 7 and the bolts, it is convenient for the staff to remove the rectangular frame 6 from the front end of the multimeter 1 for replacement in time, and it is also convenient for the staff to repair the multimeter 1.

[0025] Further, see Figure 3 and Figure 4 It can be known that the sides of the covering plates 4 that are away from each other are respectively connected with guide rods 8, and the other ends of the guide rods 8 pass through the inner wall of the rectangular frame 6 and are connected to the limiting disk 9. In the process that the covering plate 4 is subjected to thrust, the guide rods 8 connected to the side of the covering plate 4 can be forced to slide inside the rectangular frame 6 to guide the covering plate 4, thereby effectively ensuring the linear movement of the covering plate 4, thereby preventing the first spring 5 from being skewed. In combination with the setting of the limiting disk 9, the end of the guide rod 8 can be limited.

[0026] Further, see Figure 4It can be seen that a limit strip 11 is provided on the front of the rectangular frame 6, and a slider 12 is symmetrically connected to the inner side of the limit strip 11. A slide groove 13 adapted to the slider 12 is opened on the front of the rectangular frame 6. When in use, the limit strip 11 can be easily pushed to the front end of the socket 2 through the cooperation between the slider 12 and the slide groove 13, so that the plug 3 can be inserted into the interior of the socket 2. After the insertion is completed, the limit strip 11 can be set to limit the plug 3, thereby preventing the plug 3 from being pulled out from the inside of the socket 2 under force.

[0027] Further, see Figure 3 It can be seen that the inner wall of the slide groove 13 is vertically connected with the second spring 14, and the other end of the second spring 14 is connected to the slider 12. Through the setting of the second spring 14, the limit strip 11 can be effectively prevented from being easily displaced during the limiting process, thereby ensuring the limiting effect on the plug 3.

[0028] Further, see Figure 3 It can be seen that the limit strip 11 is set as a U-shaped structure, and anti-slip particles are evenly distributed on the inner side of the limit strip 11. The anti-slip particles are not shown in the figure. The limit strip 11 with a U-shaped structure and the anti-slip particles can further enhance the limiting effect of the plug 3.

[0029] Working principle: When the utility model is in use, the staff can first remove the faulty battery pack from the car, and then push up the limit strip 11, so that the limit strip 11 and the socket 2 are misaligned. At this time, the staff can insert the corresponding plug 3 into the inside of the socket 2. During the insertion of the plug 3, the two groups of cover plates 4 distributed on the front of the socket 2 are forced to move away from each other through the first spring 5 connected to the side of the cover plate 4, so as to expose the opening on the front of the socket 2. After the plug 3 is fully inserted, the staff can stop pulling the limit strip 11, so that the limit strip 11 is reset by the elastic force of the second spring 14 and moves to the center position of the socket 2, so as to limit the plug 3 engaged in the socket 2 to prevent the plug 3 from falling off during the engagement process, so as to ensure the smooth progress of the battery pack detection work. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
