[0002] The existing electric vehicle is poor in comfort and short in service life. For example, the existing foldable electric vehicle lacks mechanical structure design or is designed too simply in shock absorption, and the spring compression stroke is short after being stressed, the spring force is large, the force is large when rebounding, the person riding is easily bounced up, has certain dangerousness, and is poor in comfort. And under the influence of the interaction force, the force borne by the rear fork is also large, thus greatly affecting the service life of the frame. SUMMARY

[0003] The utility model discloses a novel folding frame which solves the problem of low service life and poor comfort of the existing electric vehicle.

[0004] To achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows: a novel folding frame, comprising a frame main body, a middle pipe is arranged at the middle part of the frame main body, the middle pipe separates the frame main body into a front triangular support and a rear fork, the rear fork is hingedly arranged with the middle pipe, a control box is arranged below the battery support frame above the rear fork, a folder is arranged at the middle part of the front triangular support, a shock absorber is arranged between the front end of the rear fork and the five-way pipe below the front triangular support, and the shock absorber is arranged in lever support with the hinge and the rear wheel shaft.

[0005] In particular, the horizontal height of the rear fork is lower than that of the front triangular support.

[0006] In particular, a handle is arranged on the front triangular support.

[0007] In particular, a battery placing rack is further arranged above the rear fork.

[0008] A folding electric vehicle is further provided, comprising the folding frame.

[0009] In particular, a handlebar frame and a front wheel arranged on the handlebar frame are arranged on the other end of the front triangular support of the folding frame, and a hydraulic shock absorber is arranged between the handlebar frame and the front wheel.

[0010] In particular, a seat is arranged at the top end of the middle pipe of the folding frame.

[0011] In particular, a controller is arranged in the controller box of the folding frame.

[0012] Compared with the prior art, the utility model has the advantages of the following:

[0013] 1, the rear fork is arranged on the middle pipe in a hinged mode, and is connected and fixed through the shockproof member, so that the folding frame has the function of shock absorption. When the rider sits on the seat of the middle pipe, the effect of good buffering and shock absorption is achieved. Meanwhile, the shockproof member, the hinge and the rear wheel axis form lever support, which can better weaken the force in the vertical direction, reduce or lower the reaction force of the folding frame on the human body, and improve the comfort of riding. By dispersing the force generated by bumping during riding, the service life of the folding frame is effectively improved.

[0014] 2, the front triangular support of the folding frame is provided with a folder, and the front triangular support can be folded through the folder, so that the length of the whole folding frame is reduced, and the purpose of folding and placing the folding frame is achieved.

[0015] 3, for the electric vehicle, the shock absorber is arranged below the front triangular support, so as to avoid occupying the position of the battery placing rack, reduce the height of the folding frame, and leave space for placing the controller box. The shockproof member, the hinge and the rear wheel axis form lever support, the shockproof member disperses the force to the rear fork, and then the force is borne by the rear wheel part, so that the force can be prevented from acting on the folder of the front cross bar, and the service life of the electric vehicle is ensured.

[0019] The utility model provides new scheme, in order to express more clearly, the utility model is explained in detail below in conjunction with the drawing.

[0020] Please see Figure 1 , the embodiment provides a novel folding frame, which comprises a frame body 1, a middle pipe 2 arranged in the middle of the frame body 1, the middle pipe 2 separates the frame body 1 into a front triangular support 3 and a rear fork 4, and the rear fork 4 is hingedly arranged with the middle pipe 2. A battery support rack 5 is arranged below the controller box 6 above the rear fork 4. A shockproof member 8 is arranged between the front end of the rear fork 4 and the five-way 7 below the front triangular support 3, the shockproof member 8 can be a shockproof spring or a hydraulic shock absorber, and the shockproof member 8, the hinge 9 and the rear wheel axis 10 form lever support.

[0021] The rear fork 4 and the middle tube 2 can be hingedly connected in the embodiment, and the shaft hole is perpendicular to the surface on which the shock absorber 8 is located. The folding frame can be applied to electric vehicles, bicycles and other vehicle models. Specifically, the rear fork 4 is arranged on the middle tube 2 in a hinged manner, and is connected and fixed through the shock absorber 8, so that the folding frame has the function of shock absorption. The control box is designed above the battery support 5 below the rear fork 4, which can reasonably utilize the space position, so that the overall height of the folding frame is lower and more compact.

[0022] When the rider sits on the seat of the middle tube 2, the effect of good buffering and shock absorption is achieved. At the same time, the shock absorber 8 and the rear wheel shaft 10 are arranged on the two sides of the hinge 9 through the lever principle, which can better reduce the vertical force and reduce or lower the reaction force of the folding frame on the human body, thereby improving the comfort of riding; at the same time, the problem of the local larger folding frame is reduced, the acting force can be dispersed through the whole frame body, the deformation or fracture of the folding frame is avoided, and the service life of the folding frame is improved. For example, when the rear wheel produces vertical displacement when bumping, the upward and downward movement of the front triangular support 3 supported by the hinge 9 can be reduced through the reverse movement of the rear fork 4 and the shock absorber 8, thereby effectively reducing the bumping feeling of the rider and improving the service life and comfort of the folding frame.

[0023] The middle part of the front triangular support in the embodiment is provided with a folder 11. The position of the front triangular support 3 can be artificially selected and cut off, and then connected through the folder 11. When the folder 11 is connected and locked, the front triangular support 3 is connected together; when the folder 11 is opened, the front triangular support 3 can be rotated at the cut-off position, the front triangular support 3 and the rear fork 4 are stacked, and the length of the folding frame is shortened, so that the folding frame is more compact after being folded.

[0024] The horizontal height of the rear fork 4 in the embodiment is lower than the horizontal height of the front triangular support 3. The front triangular support 3, the middle tube 2 and the rear fork 4 are connected to form a "Z" type structure. The height of the rear crossbar is reduced, the battery support 5 can be designed on the rear fork 4, and the height of the folding frame is controlled, so that the height of the whole folding frame is relatively lower than that of the prior art.

[0025] The battery support 5 arranged on the rear fork 4 can fix and install the storage battery through the battery support 5. Of course, if it is a bicycle, a wire basket or a seat for the rear seat can be placed, thereby improving the practicality of the folding frame.

[0026] The handle 12 is arranged on the front triangular support 3 in the embodiment, which can be held and carried after the folding frame is folded. The handle 12 is designed for easy gripping, which can better carry the folding frame and improve the practicality.
