VIBRATION DAMPING DEVICE FOR ELECTRIC DRIVING FORCE UNIT

WIPO Patent Application WO/2024/045182

A1

A vibration damping device for an electric driving force unit. The electric driving force unit comprises a base (100), a frame unit (700), a motor (200), and a battery pack and electrical unit (300). The motor is mounted on the base; the battery pack and electrical unit is fixed on the frame unit (700); the vibration damping device comprises a plurality of elastic vibration damping blocks (500); the vibration damping device is disposed between the base and the frame unit, so that the frame unit is supported on the base by means of the vibration damping device; and the frame unit and the base are connected by means of the elastic vibration damping blocks to form a soft connection. The elastic vibration damping blocks are obliquely arranged, so that stable support by the elastic vibration damping blocks for the whole machine when vibration occurs can be achieved, vibration transmitted to the battery pack and electrical unit is reduced by means of the anti-vibration effect of the elastic vibration damping blocks, and the compactness and universality of the whole device are ensured. In addition, the vibration damping structure is directly connected to the frame unit, and the vibration damping structure and the frame unit are jointly integrated at the same position of the base, so that the convenience and visibility of disassembly and assembly are improved.
