[0032] According to a first aspect of the present utility model, an integrated motor end cover is provided, as Figures 1 to 2 shown, the integrated motor end cover in this embodiment includes a main body 1 and a shock-absorbing member 2 connected to the main body 1. The main body 1 includes a cover plate portion 10 and a suspension portion 11 formed as an integrated structure to achieve the corresponding assembly of this end cover with other components of the motor, such as the motor stator and rotor or an automobile. Hereinafter, the specific structures of the above components of the integrated motor end cover according to the present utility model will be described in detail.

[0033] In this embodiment, the main body 1 is formed as a casting, that is, both the cover plate portion 10 and the suspension portion 11 are made by the casting process. In this way, on the basis of ensuring the structural strength of the main body 1, the manufacturing efficiency of the main body 1 can be further improved. In addition, the main body 1 in this embodiment is made of aluminum alloy or carbon fiber composite material to balance the lightweight of the main body 1 and the structural strength of the main body 1, thereby reducing the mass of the whole vehicle and improving the energy utilization efficiency.

[0034] Specifically, as Figures 1 to 2 shown, the cover plate portion 10 is formed as a disk-like structure. A first connecting portion 101 is formed at the first end in the thickness direction of the cover plate portion 10 for corresponding connection with the motor stator and rotor. In addition, a second connecting portion 102 is formed at the top end in the height direction of the cover plate portion 10 for corresponding connection with the motor controller. It should be noted that the specific forms and structures of the first connecting portion 101 and the second connecting portion 102 are not fixed and should be determined comprehensively according to actual situations such as the structures and assembly methods of the motor stator and rotor and the motor controller. For example, multiple threaded holes are provided in both the first connecting portion 101 and the second connecting portion 102 in this embodiment to enable screwing connection with the motor stator and rotor and the motor controller, as long as the consistency and stability of the overall structure of the motor can be ensured. It should be further noted that there are no specific restrictions on the structure, size, etc. of the cover plate portion 10, which should be determined according to actual situations to ensure that the main body 1 can stably bear the vibration force generated during the operation of the motor after being assembled with the motor, thereby ensuring the smooth operation of the motor under different working conditions.

[0035] In this embodiment, as Figures 1 to 2 shown, the suspension portion 11 is formed with a first cantilever 111 and a second cantilever 112 connected in sequence.

A third connecting portion corresponding to the vibration damping member 2 is formed at one end of the second cantilever 112 away from the first cantilever 111, and the vibration damping member 2 is vulcanized and assembled at the third connecting portion. It should be noted that there are no specific restrictions on the specific structural specifications of the suspension portion 11, such as the shapes and sizes of the first cantilever 111 and the second cantilever 112, and the connection position of the suspension portion 11 and the cover plate portion 10. It should be determined comprehensively according to actual situations such as the installation position of the motor and the vehicle, as long as the assembly requirements and usage requirements of the motor can be met.

[0036] Furthermore, the shock absorber 2 in this embodiment is formed with an elastic rubber member. A through hole 21 is formed at the center of the shock absorber 2 for corresponding connection with the vehicle body bracket. Further still, the shock absorber 2 is formed with a plurality of hollow structures 22 around the through hole 21, and the plurality of hollow structures 22 are evenly distributed, so as to effectively increase the elastic modulus of the shock absorber 2, thereby effectively isolating and reducing the vibration and noise generated during the operation of the motor, and improving the riding comfort and vehicle stability. It should be noted that the shape, size, quantity, etc. of the hollow structure 22 are not specifically limited, as long as it can help the shock absorber 2 achieve the above technical effects.

[0037] In addition, in this embodiment, the main body 1 is further formed with a reinforcing portion to increase the impact resistance and vibration resistance of the main body 1, thereby ensuring that the integrated structure of the main body 1 and the shock absorber 2 can maintain stable and reliable performance under various extreme working conditions. The reinforcing portion in this embodiment includes a plurality of reinforcing ribs 31 provided on the outer surface of the main body 1; in addition, as Figure 2 shown, two grooves 30 are formed at the second cantilever 112 described above to achieve the lightweight of the main body 1, and the space between the two grooves 30 forms the reinforcing rib 31.

[0038] According to the integrated motor end cover of the present invention, the motor end cover includes a main body 1, and the main body 1 specifically includes a cover plate portion 10 and a suspension portion 11 formed integrally. Compared with the separately provided suspension and end plate in the prior art, the motor end cover in the present invention is formed as an integrated structure, effectively improving the strength of the motor end cover and the overall structure of the motor, effectively reducing the space occupied by the motor end cover (the assembly structure between the end cover and the suspension is omitted), and reducing the manufacturing cost and assembly time. By optimizing the material selection of the main body 1, the operation efficiency and stability of the motor can be improved.

[0039] In addition, the main body 1 in the present invention is further connected with a shock absorber 2 to improve the smoothness and comfort during the operation of the vehicle after the motor is assembled.
