[0087] To avoid water entering the inside of the shell 141 through the outlet hole 145, a sealing member 148 is arranged in the opening. The sealing member 148 can be tightly connected with the cable and the protruding part 147. The sealing member 148 is arranged at the opening of the outlet hole 145. The sealing member 148 can seal the opening. The sealing member 148 can seal the opening along the axial direction of the protruding part 147. The sealing member 148 is made of a sealing material, such as sealing glue or sealing gasket. The outlet hole 145 is sealed by gluing. In this way, water is prevented from entering the inside of the shell 141 through the outlet hole 145, thereby avoiding water contacting the battery 140 through the outlet hole 145.

[0088] As shown in Figure 9As shown, a vent 149 is provided on the housing 141. The vent 149 penetrates the housing 141. Optionally, the vent 149 is provided on the second housing 143. The vent 149 penetrates the second housing 143. The vent 149 is constructed as a generally circular hole. The vent 149 is used for heat dissipation and balancing the internal and external air pressure of the housing 141, preventing the housing 141 from bulging, deforming, or even cracking due to excessive internal pressure.

[0089] like Figures 5 to 10 As shown, the housing 141 also includes a waterproof and breathable component 150, which covers the vent 149. The waterproof and breathable component 150 has both waterproof and breathable functions. The waterproof and breathable component 150 is disposed outside the vent 149. The waterproof and breathable component 150 can seal the vent 149, thereby dissipating heat and balancing the internal and external air pressure of the housing 141, preventing structural damage or seal failure due to excessive pressure difference. The waterproof and breathable component 150 prevents the vent 149 from contacting water, making the housing 141 waterproof and breathable, and preventing water from entering the housing 141 through the vent 149.

[0090] The waterproof and breathable component 150 can be composed of a waterproof and breathable membrane, a waterproof and breathable valve, and a waterproof and breathable fabric.
