The chassis of robot equipment has high versatility and is usually integrated with mobile structures, energy storage structures, etc. Usually, the energy storage structure of robot equipment mostly uses battery units. Considering the battery life of robot equipment, the general chassis is also equipped with a power interface to replenish the energy of the battery unit.

Therefore, adding multiple charging structures to the chassis is the current research focus in this field.

Secondly, through the conductive heat sink 151 extending one end into the installation area 12 and the other end extending to the edge of the bottom plate 1, the heat accumulated in the installation area 12 can be effectively conducted to the air around the bottom plate 1 through the conductive heat sink 151, and the heat dissipation effect is effectively improved.

[0083] like Figure 7 As shown, in some optional embodiments of the present application, the heat sink assembly further includes a converging heat sink 152, the shape of the converging heat sink 152 is consistent with the projection of the converging member 11 on the bottom plate 1, and the setting position of the converging heat sink 152 corresponds to the setting position of the converging member 11. By setting the converging heat sink 152, a heat dissipation effect can be provided for the converging member 11 in a targeted manner.
