Description

Technical Field

[0001] The utility model relates to the technical field of automotive drive motors, and particularly to a drive motor mounting bracket. Background Art

[0002] The drive motor mount is to install the drive motor of the electric vehicle under the chassis and suspend it on the vehicle chassis, and connect it to the wheels through a drive shaft. Different from the mechanical transmission method used by traditional automotive engines, the drive motor mount uses an electric drive method, which is more efficient and environmentally friendly. The drive motor mount mainly plays the role of driving the wheels. Because it is directly installed under the wheels, it can better transfer energy to the wheels, thereby improving the power performance and acceleration of the vehicle.

[0003] At present, after most motor mounting brackets are connected and installed to the vehicle, due to the large vibration generated by the motor during operation and the lack of buffering and shock absorption between the motor and the mounting bracket, the vibration over a long time will cause the connection to become loose, and even cause the risk of the motor falling off. Therefore, it is necessary to design a drive motor mounting bracket that can effectively buffer and damp the vibration of the drive motor to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a drive motor mounting bracket to solve the problems raised in the above background art.

[0005] A drive motor mounting bracket of the utility model includes a motor body. An output shaft is arranged at one end of the motor body. First and second support components are respectively arranged on the outer side of the motor body near and far from the output shaft. The first support component includes a first support frame and a first mounting plate, and the second support component includes a second support frame and a second mounting plate. A connecting rod is arranged at a position near the bottom end between the first support frame and the second support frame; a buffer component is arranged above the connecting rod, and the buffer component includes a buffer spring, a telescopic rod and a support plate.

[0006] As a further improvement of the utility model, the first support component further includes a limiting strip, a first fixing plate, a fixing block and a limiting groove. The first support frame is designed in a U-shaped structure, and the first mounting plates are respectively arranged at positions near the top and bottom ends on both sides of the first support frame.

[0007] As a further improvement of the utility model, the fixing blocks are arranged on both sides of the top end of the first fixing plate. The first fixing plate is connected to both sides of the top end of the first support frame through the fixing blocks and bolts. The limiting grooves are opened on both sides of the top end of the motor body, and the limiting strip is movably inserted between the limiting groove and the first fixing plate.

[0008] As a further improvement of the present utility model, the second support assembly further includes a limit plate, a second fixing plate and a fixing screw. The second support frame is also designed in a U-shaped structure. The second mounting plate is arranged at positions near the top and bottom on both sides of the second support frame.

[0009] As a further improvement of the present utility model, the second fixing plate is connected to the top end of the second support frame by bolts. The limit plate is arranged in an arc shape on the upper surface of the tail end of the motor body. The fixing screw threadedly penetrates through the second fixing plate and is connected to both sides of the top end of the limit plate through bearings.

[0010] As a further improvement of the present utility model, the buffer assembly further includes a protective cover and a connecting block. There are several support plates and all of them are in contact with the outer surface of the motor body. One end of the telescopic rod is connected to the end of the support plate far from the motor body and the other end is connected to the inner wall of the protective cover. The buffer spring is sleeved on the outer surface of the telescopic rod.

[0011] As a further improvement of the present utility model, the protective cover is designed in a semi-circular structure. The connecting blocks are arranged on both sides of the bottom end of the protective cover and on both sides of the top end of the connecting rod. The protective cover is connected and fixed to the connecting rod through the connecting blocks.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By arranging the protective cover and the support plate in the present utility model, in cooperation with the telescopic rod and the buffer spring, when the motor body generates vibrations, the telescopic rod and the spring will be compressed. Through the spring and the resilience buffer, the vibrations of the connection part are reduced, thereby preventing the connection part from being loosened due to vibrations.

[0014] 2. At the same time, by using the arranged first support frame and second support frame, in cooperation with the limit strip and the limit plate, the head and tail of the motor body can also be effectively buffered and shock-absorbed. While making the installation of the motor body more stable, the shock-absorbing effect of the suspension bracket is further improved. BRIEF DESCRIPTION OF THE DRAWINGS
