 technical problem

 [0003] In the prior art folding type vehicle, the folding process has many complicated steps, and the processing of the brake line during the folding process of the component is relatively simple, and a long length is reserved for folding. However, the bending degree is often high. After a period of folding and storage, the brake wire is not easy to recover. After several folding or folding, the brake wire is often broken, and the service life is short. The material is also simply pursued from the aspect of toughness and elasticity. This type of problem cannot be resolved.

 Problem solution

 Technical solution

 [0004] The purpose of the present invention is to provide a hand brake for folding an electric vehicle in order to completely solve the above-mentioned technical problems, and to realize free bending of the brake wire, smooth bending, firm connection, and not easy to break to achieve the above A purpose is to design a handbrake of a folding electric vehicle, comprising a handle, a bracket and a brake wire, wherein the handle is provided with a return spring, one end of the brake wire is connected with the handle, and the other end is connected with the brake disk.

The brake wire set has a circular or cylindrical body, the handle has a peripheral fluorescent layer, and both end faces of the cylindrical body are arranged in an arc shape, the handle is connected with a bracket shaft, and the bracket is provided with a snap ring. The snap ring is used to fit over the handlebar. . Advantageous effects of the invention

 Beneficial effect

[0005] Advantageous Effects: The utility model can realize the free bending of the brake wire, the bending is smooth, the connection is firm, and the folding is not easy. Brief description of the drawing

 BEST MODE FOR CARRYING OUT THE INVENTION

 BEST MODE FOR CARRYING OUT THE INVENTION

 [0012] As shown in the figure, a handbrake of a folding electric vehicle includes a handle 1, a bracket 2 and a brake wire 3, wherein the handle 1 is provided with a return spring 4, and the brake wire 3 end is connected to the handle 1, and One end is connected to the brake disc 5, and the brake wire 3 is provided with a circular body 6 or a cylindrical body. The handle 1 has a peripheral fluorescent layer, and the cylindrical body end portion 7 is arranged in an arc shape. The handle 1 is axially connected to the bracket 2 . The bracket 2 is provided with a snap ring 8 for socketing on the handlebar 9.

 Embodiment 1

 [0014] A hand brake for folding an electric vehicle, comprising a handle 1, a bracket 2 and a brake wire 3, the handle 1 is provided with a return spring 4, the brake wire 3 - end is connected to the handle 1 and the other end is connected to the brake disk 5, The brake wire 3 is provided with a plurality of circular bodies 6 or cylindrical bodies. The handle 1 is provided with a fluorescent layer, a circular body 6 or a cylindrical body is connected in series on the brake wire 3, and the circular body 6 can be selected from steel balls or plastic balls. The handle 1 is provided with a return spring 4, the brake brake brake line 3 is tightened, the handle 1 is automatically rebounded, the brake wire 3 is tightened, and the brake is transmitted to the brake disc 5 to realize the brake. The circular body 6 or the cylindrical body functions as a common rubber sleeve to protect the brake wire 3. In the folding body, the brake wire 3 is bent and deformed accordingly, and the circular body 6 or the cylindrical body can avoid excessive bending. The effect does not form a 180 degree discount. The handle 1 is provided with a fluorescent layer, and the handle 1 can be set as a see-through cavity. The phosphor is placed in the cavity, and the night travels to decorate the light, and can also reflect the light of the opposite vehicle to other pedestrians. And the vehicle plays a warning role.

[0015] Example 2 [0016] Further, based on the first embodiment, the two end faces of the cylindrical body are arranged in an arc shape, and the cylindrical body is worn on the brake wire 3, and the arc is arranged to make the contact between the two cylindrical bodies smooth, and the bending is performed. The two cylindrical bodies are in close contact, and the brake wire 3 is folded smoothly as a whole.

 [0017] Example 3

 [0018] Further, based on the embodiment 1 or 2, the handle 1 is pivotally connected to the bracket 2, the handle 9 is provided with a bracket 2, and the movable shaft is disposed on the bracket 2, and the handle 1 is connected to the bracket 2 through the movable shaft, the handle 1 can be moved around the axis, and the handle 1 is also provided with a return spring 4.
