Abstract
Description
Technical Field
[0001] The utility model relates to a frame structure of an electric vehicle. Background Art
[0002] Electric bicycles are widely used. Existing electric bicycles are generally small models, especially the commonly used substitute driving vehicles. Such vehicles have the characteristics of small models and large loads. When in use, the existing shock absorbers cannot meet the user's needs, resulting in a poor user experience. Summary of the Utility Model
[0003] The utility model provides a frame structure of an electric vehicle, which includes a main frame, a main beam tube and a rear fork. The main beam tube is arranged at the front end of the main frame, and the rear fork is arranged at the rear end of the main frame. A first connecting arm and a second connecting arm are arranged on the rear fork. The first connecting arm is axially connected to the main frame. A shock absorption mechanism is arranged on the second connecting arm. One end of the shock absorption mechanism is axially connected to the main frame, and the other end is axially connected to the second connecting arm. The first connecting arm, the second connecting arm and a part of the main frame are combined to form an arch.
[0004] In one or more embodiments, the first connecting arm and the second connecting arm are integrally formed and form an arc.
[0005] In one or more embodiments, a third connecting arm is further arranged on the rear fork. The third connecting arm extends obliquely backward from top to bottom and is fixedly connected to the first connecting arm and the second connecting arm.
[0006] In one or more embodiments, the second connecting arm is provided with an extending arm extending upward, and the extending arm is axially connected to the main frame.
[0007] In one or more embodiments, the main frame is provided with an extending beam extending towards the main beam frame. The extending beam is axially connected to the main beam frame and forms a foldable structure.
[0008] In one or more embodiments, a locking part is arranged between the main beam frame and the extending beam. The locking part can be opened to enable the main beam frame and the extending beam to be folded, or the locking part can lock the main beam frame and the extending beam in a non-folded state.
[0009] In one or more embodiments, a strengthening arm is further arranged between the extending beam and the main frame bracket. The strengthening arm is located below the extending beam.
[0010] In one or more embodiments, a carrying beam is further arranged above the extending beam.
[0011] Advantages of the present utility model: A shock absorption mechanism is provided between the main frame and the rear fork frame to form the first shock absorption. At the same time, the combination of the first connecting arm, the second connecting arm and a part of the main frame forms an arch. Since the arch has a deformation space and a resilience amount, this forms the second shock absorption, making the shock absorption effect of the electric bicycle higher and meeting the user's usage needs.
