Detailed Description

Referring to fig. 1-5, in an embodiment of the present invention, a housing for a power module includes a lower housing 1 and an upper housing 2 movably connected to the upper side of the lower housing 1;

the system is composed of a power management main control module, a first current sensor module, a second current sensor module, a voltage sensor module, a temperature sensor module, a protection circuit module and a battery charging and discharging control module. The first current sensor module, the second current sensor module, the voltage sensor module, the temperature sensor module, the overcurrent and protection circuit module and the battery charging and discharging control module are all connected with the power management main control module.

Go up and seted up ventilation hole 3 on the casing 2, go up elastic connection in the casing 2 and have push pedal 4, the one end of push pedal 4 is passed the lateral wall of casing 2 and is extended to its outside, fixedly connected with dust removal board 5 on the push pedal 4, and dust removal board 5 cooperatees with ventilation hole 3.

Go up and connect through locking bolt 6 between casing 2 and the lower casing 1, be convenient for realize through locking bolt 6 that the installation is with dismantling between casing 2 and the lower casing 1.

The side wall of the upper shell 2 is provided with a through hole 7 for the push plate 4 to pass through.

Fixedly connected with spring 8 on the lateral wall of through-hole 7, spring 8's lower extreme and push pedal 4 fixed connection are convenient for realize elastic connection between push pedal 4 and the last casing 2 through spring 8.

The soft pad 9 is fixedly connected to the push plate 4 positioned on the outer side of the upper shell 2, and the comfort level of hands is improved through the soft pad 9.
