Stretching springs 301 are installed on the surfaces of the arc-shaped card members 3032. One end of the stretching spring 301 is fixed to the inner wall of the groove 302.

[0029] During implementation, one end of the user's mounting post 106 moves to the outside of the mounting plate 104. Under the elastic force of the stretching spring 301 inside the groove 302, the arc-shaped card member 3032 is driven to move, so that the arc-shaped card member 3032 slides inside the groove 302. Under the elastic force of the stretching spring 301, the arc-shaped card member 3032 is driven to be clamped into the arc-shaped card slot 3031. Under the clamping action of the arc-shaped card slot 3031 and the arc-shaped card member 3032, the mounting post 106 is installed on the surface of the mounting plate 104, thereby installing the module box body 1 on the surface of the battery housing 102 to realize the function of self-locking installation of the management module.

[0030] Furthermore, as Figure 3 and Figure 6 shown, anti-disconnection mechanisms 4 are provided on the surfaces of the module box bodies 1.

[0031] During implementation, the user plugs the external power cord onto the surface of the connection port 105. At this time, under the elastic force of the telescopic spring 402, the clamping plate 401 is driven to move. At this time, under the elastic force of the telescopic column 403 and the spring body 404 inside the clamping plate 401, the rubber pad 405 is driven to move, so that the rubber pad 405 moves to contact the surface of the cord. Under the combined action of the clamping plate 401 and the rubber pad 405, the cord is clamped and fixed on the surface of the connection port 105. Under the action of the rubber pad 405, the surface of the cord is protected, preventing the cord from becoming loose on the surface of the connection port 105 during the use of the management module, so as to achieve the function of preventing disconnection of the management module.

[0032] Working principle: When in use, first place the module box body 1 at the designated position. One end of the user installation column 106 moves to the outside of the mounting plate 104. Under the elastic force of the extension spring 301 in the groove 302, the arc-shaped clamping member 3032 is driven to move, so that the arc-shaped clamping member 3032 slides inside the groove 302. Under the elastic force of the extension spring 301, the arc-shaped clamping member 3032 is driven to be clamped into the arc-shaped card slot 3031. Under the clamping action of the arc-shaped card slot 3031 and the arc-shaped clamping member 3032, the installation column 106 is installed on the surface of the mounting plate 104, thereby installing the module box body 1 on the surface of the battery housing 102, so as to achieve the function of self-locking installation of the management module, making it convenient for the user to install the module box body 1 and the control chip 103 on the surface of the battery housing 102 when using the management module, enabling the management module to automatically perform self-locking installation during installation, and preventing the management module from becoming loose during use.

[0033] Subsequently, the user plugs the external power cord onto the surface of the connection port 105. At this time, under the elastic force of the telescopic spring 402, the clamping plate 401 is driven to move. At this time, under the elastic force of the telescopic column 403 and the spring body 404 inside the clamping plate 401, the rubber pad 405 is driven to move, so that the rubber pad 405 moves to contact the surface of the cord. Under the combined action of the clamping plate 401 and the rubber pad 405, the cord is clamped and fixed on the surface of the connection port 105. Under the action of the rubber pad 405, the surface of the cord is protected, preventing the cord from becoming loose on the surface of the connection port 105 during the use of the management module, so as to achieve the function of preventing disconnection of the management module, thus preventing the cord from becoming loose from the surface of the connection port 105 when using the management module, enabling the management module to stably plug the cord on the surface of the connection port 105 when in use, and preventing the module box body 1 from having poor contact due to cord loosening during the use of the management module.

[0034] Subsequently, when the control chip 103 inside the module box body 1 is damaged, the user tightens the mounting screw 201 on the surface of the cover body 101, and then pulls the control chip 103 inside the module box body 1, so that the control chip 103 drives the guiding slider 202 to slide inside the guiding chute 2031. Under the combined action of the guiding slider 202 and the guiding chute 2031, the control chip 103 is guided. At this time, the control chip 103 drives the positioning card 2033 away from the inside of the positioning slot 2032, so as to extract the control chip 103 from the inside of the module box body 1, and perform maintenance and repair on the surface of the control chip 103. When the repaired control chip 103 is placed inside the module box body 1, at this time, the control chip 103 drives the positioning card 2033 to be stuck into the inside of the positioning slot 2032, and the control chip 103 is fixedly installed inside the module box body 1, so as to realize the function of the management module for overhauling and replacing the control chip 103, so that it is convenient for the user to extract the control chip 103 from the inside of the module box body 1 to perform maintenance and replacement on the surface of the control chip 103 when the management module is in use, greatly extending the service life of the management module. When the control chip 103 fails, it can be repaired and maintained in time, and finally the use of the charge and discharge management module is completed.
