detailed description

In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

Example 1:

As shown in FIG. 1 , in order to allow the battery management module to dissipate heat during operation, the housing body 1 of the battery management housing is usually provided with vent holes 2 . However, in a humid environment, humid air enters the battery management module through the vent hole 2, which affects its lifespan. For this reason, as shown in accompanying drawings 2 to 3, in this embodiment, a movable window leaf 4, a window leaf control device and a movable window leaf starting device are also provided in the battery management shell 1, and each air hole 2 is correspondingly provided with a movable window Leaf 4, the movable window leaf control device includes a fixed rod 3, a control rod 5 and a driving device 6, one end of the fixed rod 3 is preset above the air hole 2 on the battery management shell 1, and the other end is hinged to the top of the movable window leaf 4 , the movable window blade 4 can be rotated by the fixed rod as the axis, the lower end of the movable window blade 4 is mechanically connected with the driving device 6 through the control rod 5, and the driving device 6 drives the bottom of the movable window blade to move horizontally through the control rod 5. The above-mentioned driving device 6 adopts a micro motor, and the movable window blade 4 adopts a rubber sheet.

The controller includes a temperature acquisition module, a humidity acquisition module and a central processing unit, the temperature acquisition module is arranged in the shell body 1, the number of humidity acquisition modules is two, and each is arranged on the inside and outside of the shell body 1, the temperature acquisition module and The humidity collecting modules are electrically connected to the central processing unit, and the central processing unit is in communication connection with the driving device.

When the utility model is working, the humidity sensor is used to collect the humidity inside the battery management shell 1. When the humidity exceeds the set humidity, such as 95% humidity, the controller controls the operation of the micro motor through the communication signal, thereby driving the control rod 5 to descend, so that the activity The shutters are closed to reduce the entry of moisture, and when the external humidity is 5% lower than the internal humidity, the movable shutters are opened.

The temperature inside the battery management shell 1 is collected by the temperature sensor. When the temperature exceeds the set temperature, such as 50°C, the controller controls the operation of the micro-motor through the communication signal, and drives the control rod 5 to rise, so that the movable window leaves are opened, and the inside of the shell The heat is dissipated.

When the set humidity is exceeded and the set temperature is exceeded, the movable window leaves are opened to protect the equipment.

Example 2:
