[0002] In modern electric vehicle design, the design of the rear suspension assembly structure plays a vital role in the performance, stability and maintenance convenience of the vehicle. The traditional electric vehicle rear suspension structure usually adopts a double-sided flat fork and double-sided rear shock absorber design. This structure has certain advantages in providing stability and carrying capacity, but it is cumbersome when repairing and replacing tires.

[0003] The traditional rear suspension assembly structure of electric vehicles generally has the following problems and shortcomings:

[0004] 1. Inconvenient maintenance: Due to the design of double-sided flat forks and double-sided rear shock absorbers, the vehicle needs to disassemble multiple parts when replacing tires or wheels, which not only increases the complexity of maintenance, but also prolongs the maintenance time.

[0005] 2. Complex structure: The design of the double-sided flat fork and double-sided rear shock absorber makes the overall structure complex, increasing the manufacturing cost and assembly difficulty.

[0006] 3. Heavy weight: The traditional double-sided flat fork design makes the rear suspension part heavy, which is not conducive to the lightweight design of electric vehicles, and thus affects the cruising range and energy efficiency of electric vehicles. Utility Model Content

[0007] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a new type of rear suspension assembly structure for electric vehicles. The structure adopts the design of a single-sided flat fork and a single-sided rear shock absorber, and the motor hub is designed as a side-mounted structure, which significantly simplifies the structure of the rear suspension part. Through this design, when replacing the wheel hub and tire of the vehicle, there is no need to disassemble too many parts, which greatly improves the convenience and efficiency of maintenance.

[0008] The technical solution adopted by the utility model is as follows: the utility model provides a novel rear suspension assembly structure of an electric vehicle, including a frame, a rear fork, a rear shock absorber, a rear brake bracket, a rear brake, a brake disc, a motor, a wheel hub and a tire; wherein the frame is used to connect the rear fork and the rear shock absorber; the rear fork is used for the rocker arm function; the rear shock absorber is used to provide a buffering effect; the rear brake bracket is used to install the rear brake and limit it; the rear brake cooperates with the brake disc to realize rear wheel braking; the motor is used to provide power; the wheel hub is used to support the tire; and the tire is used to support the vehicle.

[0009] Furthermore, the frame and the rear fork are fastened together via a bolt shaft and a first nut.

[0010] Furthermore, two ends of the rear shock absorber are respectively connected to the rear flat fork and the frame, and are fastened by a first bolt and a second nut.

[0011] Furthermore, the rear brake bracket is mounted on the rear flat fork and is used to fix the rear brake.

[0012] Furthermore, the brake disc is fixed to the motor via a second bolt, and the motor is connected to the rear brake bracket via a flat key.

[0013] Furthermore, after the wheel hub and the tire are assembled, they are connected to the motor via a third bolt.

[0014] Furthermore, the rear brake is fixed to the rear brake bracket by a fourth bolt and is fastened by a spring washer and a second nut.

[0015] Furthermore, the motor is installed at the center of the rear fork to drive the wheel hub and tire to rotate.

[0016] Beneficial effects of the utility model:

[0017] Based on the above technical solution, the utility model solves the problems of inconvenient maintenance, complex structure and heavy weight of the traditional electric vehicle rear suspension structure by simplifying the design and optimizing the connection method. In the assembly structure, the frame and the rear fork are fastened by bolt shafts and nuts, which simplifies the disassembly process and makes it more convenient to repair and replace tires. At the same time, the two ends of the rear shock absorber are respectively connected to the rear fork and the frame, and fastened by bolts and nuts, which improves the stability and reliability of the overall structure.

[0018] The rear brake bracket is installed on the rear fork to fix the rear brake and ensure the stability of the brake system. The brake disc is fixed to the motor by bolts, and the motor is connected to the rear brake bracket by a flat key. This design not only improves the stability of the installation, but also simplifies the assembly and maintenance process. After the wheel hub and tire are assembled, they are connected to the motor by bolts, making it more convenient to replace the tire.
