Description

Technical Field

[0001] This utility model relates to the field of vehicle frames, and in particular to vehicle frames with shock absorption function. Background Technology

[0002] Electric bicycles are a traditional mode of transportation, aligning with environmental protection principles by not polluting the environment and providing exercise, thus enjoying widespread popularity. Traditional electric bicycle frames are manufactured using welding and other fixed methods, resulting in a lack of shock absorption after production. However, during use, users frequently encounter various road conditions, with uneven surfaces directly contacting the tires. Vibrations are transmitted from the tires to the frame, and then from the frame to the rider, causing discomfort and even a tendency to lean forward. Therefore, frames with shock absorption capabilities have been developed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A vehicle frame with shock absorption function includes a front frame. One end of the front frame is obliquely welded with a vehicle beam frame, and the other end of the vehicle beam frame is welded with a seat fixing seat. A connecting frame is vertically installed at the bottom end of the seat fixing seat, and the bottom end of the connecting frame is connected to the front frame. A shock absorber is installed between the connecting frame and the front frame. A first arc-shaped movable frame is movably installed at the top of the shock absorber, and the other end of the first arc-shaped movable frame is movably connected to the connecting frame. A second arc-shaped movable frame is movably installed at the bottom end of the shock absorber, and the bottom end of the second arc-shaped movable frame is movably connected to the other end of the front frame. A first rear frame is movably connected to the other side of the first arc-shaped movable frame, and a second rear frame is movably connected to the other side of the second arc-shaped movable frame.

[0005] Preferably, a connector is provided between the front frame and the frame beam, and the connector is vertically located at one end of the front frame. A drive shaft mounting bracket is vertically provided on one side of the connector, and a first wheel mounting bracket is horizontally provided at the bottom end of the drive shaft mounting bracket. The first wheel mounting bracket rotates at the bottom end of the drive shaft mounting bracket.

[0006] Preferably, the other end of the second rear frame is fitted and connected to the other end of the first rear frame, and a second wheel mounting bracket is provided at the connection between the second rear frame and the first rear frame.

[0007] Compared with the prior art, the beneficial effects of this utility model are: the frame is formed by combining the front frame, frame beam, seat fixing seat, first rear frame and second rear frame, and the frame can be combined with vehicle accessories to form an electric vehicle. Furthermore, through the cooperation between the first arc-shaped movable frame, the second arc-shaped movable frame and the shock absorber, the electric vehicle formed by the frame and other vehicle accessories has the effect of shock absorption and shock damping during driving.

[0008] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
