Description

Technical Field

[0001] The utility model belongs to the technical field of electric bicycles, and in particular relates to a heating handlebar cover for an electric bicycle and an electric bicycle. Background Art

[0002] When riding an electric vehicle (electric bicycle or electric motorcycle, etc.) in cold seasons, hands are easily frozen, which reduces the user experience and also leads to certain riding safety risks. A very common practice is to put warm gloves on the handlebars, which not only affects the appearance, but also restricts the space for hand movement, has great limitations, and is dangerous.

[0003] Another approach is to add a heating component to make the handle heat up. The heating component usually uses a resistance wire to generate heat. However, the process of winding the resistance wire onto the inner lining of the handle is mostly done manually, which is inefficient, and the quality of the resistance wire winding is not easy to guarantee, and the position of the resistance wire is also difficult to maintain (resulting in uneven heating). There are also very few practices that use detachable heating rings, but in this approach, a heating ring installation cavity must be formed on the injection-molded rubber sheath, which makes the radial size of the handle larger and also brings wiring problems. Summary of the invention

[0018] An electric bicycle comprises the aforementioned heating grip cover for the electric bicycle.

[0019] As an improvement of the electric bicycle, the electric bicycle also includes a wiring assembly and a controller. The controller and the heating sheet are connected through the wiring assembly. The wiring assembly includes a power connector, a control connector and two heating connectors. The two flexible heating sheets are controlled by the same controller.

[0020] The beneficial effects of the heating handlebar cover of the electric bicycle of the utility model are: it includes an inner lining, a flexible heating sheet and a sheath, the flexible heating sheet is coated on the inner lining, and the sheath is integrally formed by injection molding.
