[0006] The heat absorption mechanism includes an air inlet box connected to the air outlet of the electric control cabinet and a fan connected to the air outlet of the air inlet box, and the heat in the electric control cabinet is absorbed by the fan and discharged from the air outlet of the fan;

[0007] The heat dissipation mechanism includes a fan for supplying air, an air outlet box connected to the air outlet of the fan, and a hard hose air duct connected to the air outlet of the air outlet box, the soft end of the hard hose air duct is connected to the rear axle housing, and the wind supplied by the fan is used to dissipate heat for the wheel side motor in the rear axle housing;

[0008] The fan is electrically connected to the controller, and the speed of the fan is adjusted by the controller.

[0009] Preferably, the hard hose air duct is composed of a steel pipe connected to the air outlet of the air outlet box and an aramid cloth tube connected to the air outlet of the steel pipe, and is connected to the rear axle housing through the aramid cloth tube.

[0013] Preferably, the controller is also electrically connected to the electric control cabinet and / or the wheel-side motor for receiving temperature information.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model uses an aramid cloth tube as an air duct connecting the fan and the rear axle housing. The soft texture of the aramid cloth tube enables the air duct to be used in a narrow and rugged vehicle space for connection with the rear axle housing. There is no need to set up an additional air duct road without changing the vehicle space, thereby reducing unnecessary space occupation of the vehicle and making the vehicle more compact. The controller receives temperature signals from the electric control cabinet and the wheel-side motor, and dynamically adjusts the rotation speed of the fan through the feedback temperature signal, thereby solving the problem of energy waste in the prior art and being more energy-saving and environmentally friendly.

[0022] The heat dissipation mechanism is provided with a fan 3 for supplying air, the air outlet of the fan 3 is connected with the air inlet of the air outlet box 4, the air outlet of the air outlet box 4 is connected with a hard hose air duct in a circular shape, the hard hose air duct consists of a steel pipe 5 connected with the air outlet of the air outlet box 4, the air outlet of the steel pipe 5 is connected with the air inlet of the aramid cloth tube 6, the air outlet of the aramid cloth tube 6 is connected with the air inlet of the rear axle housing 7; the wind supplied by the fan 3 dissipates the heat of the wheel-side motor 8 in the rear axle housing 7.

[0023] In this embodiment, the fan 3 is connected to the air inlet box 2 and the air outlet box 4 via a hose clamp. The air outlet box 4 is also connected to the steel pipe 5 via a hose clamp.

[0024] The fan 3 is electrically connected to the controller, and the controller is also electrically connected to the electric control cabinet 1 and the wheel motor 8 to receive temperature information. The controller adjusts the speed of the fan 3 according to the real-time temperature feedback of the electric control cabinet 1 and the wheel motor 8.
