In the actual use process of electric vehicles, braking is often achieved through a braking mechanism. Most existing electric vehicle brakes use a disc brake disc and its corresponding brake pads for braking.

[0003] However, in the actual use process, the contact area between the brake pads and the brake disc is small, and the brake pads are generally only arranged on one side of the brake disc, and it is easy to slip during the braking process, resulting in a reduction in braking quality and affecting the driving safety of electric vehicles. Summary of the Invention

[0005] The utility model is realized through the following technical solutions: a dual-brake structure of an electric vehicle with an anti-slip design, including a brake disc and a plurality of brake seats. The brake seats are sleeved outside the brake disc. A first brake pad is installed on the inner circumferential surface of the brake seat. Second brake pads are installed on both side surfaces inside the brake seat. One end of each brake seat is bent to form a diversion part with an annular structure. On one side of the plurality of diversion parts, there is a brake moving part for inwardly pressing the diversion parts to push the brake seats to move closer to each other. The outer end faces of the plurality of diversion parts are all bent to form fixing parts, and a connecting flange is provided outside the fixing parts.

[0006] As a preferred technical solution, chutes are provided on the inner side surfaces of the connecting flanges corresponding to the fixing parts, sliders are installed on the outer side surfaces of the fixing parts corresponding to the chutes, the sliders are all slidably arranged in the chutes, and a plurality of compression springs are installed between the sliders and the chutes.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a dual-brake structure of an electric vehicle with an anti-slip design according to the present utility model includes a brake disc 1 and a plurality of brake seats 2. The brake seats 2 are sleeved outside the brake disc 1. A first brake pad 4 is installed on the inner circumferential surface of the brake seat 2. Second brake pads 5 are installed on both side surfaces inside the brake seat 2. One end of each brake seat 2 is bent to form a diversion part 12 with an annular structure. On one side of the plurality of diversion parts 12, there is a brake moving part 7 for squeezing the diversion part 12 inward to push the brake seats 2 to move closer to each other. The outer end faces of the plurality of diversion parts 12 are all bent to form a fixing part 13, and a connecting flange 6 is provided outside the fixing part 13.

[0022] In this embodiment, chutes are provided on the inner side surfaces of the connecting flange 6 corresponding to the fixing parts 13. Sliders 15 are installed on the outer side surfaces of the fixing parts 13 corresponding to the chutes. The sliders 15 are all slidably arranged in the chutes, and a plurality of compression springs 14 are installed between the sliders 15 and the chutes. The cross-sections of the sliders 15 and the chutes are both trapezoidal structures. Among them, the connecting flange can be fixed on the frame of the electric vehicle. After the connecting flange is fixed, the brake seats can only move with the connecting flange as the fixed point.

[0023] In this embodiment, the opposite surfaces of the second brake pads 5 are both inclined to form a first brake surface 16. Both sides of the brake pads protrude to form a second brake surface 3 with an annular structure. The cross-section of the second brake surface 3 is inclined and is arranged parallel to the first brake surface 16.

[0024] In this embodiment, the cross-sections of the brake seats 2 are all in a "U" shape. The second brake pads 5 are all arranged on both sides of the brake disc 1, and the first brake pads 4 are all arranged outside the outer circle of the brake disc 1.

[0025] In this embodiment, the brake moving member 7 is arranged in a "C" shape, and the open end of the brake moving member 7 is arranged close to the outer circumferential surface of the flow guiding portion 12, so that after the brake moving member moves towards the flow guiding portion, the upper end surface of the brake moving member can be squeezed against the arc surface of the outer circumference of the flow guiding portion, thereby squeezing the brake seat inward.

[0026] In this embodiment, a pull rod 9 is installed on the end surface of the brake moving member 7. A fixed seat is installed at one end of the pull rod 9 away from the brake moving member 7. A wiring hole 10 for inserting the brake wire is provided on the fixed seat. A screw 11 hole communicating with the wiring hole 10 is provided at one end of the fixed seat. A screw 11 for pressing the brake wire is threadedly connected in the screw 11 hole. A positioning sleeve 8 is sleeved on the pull rod 9, and one end of the positioning sleeve 8 is installed on the connecting flange 6; wherein, a compression spring can also be installed on the pull rod. One end of the compression spring can be installed on the brake moving member, and the other end is installed on the positioning sleeve. Therefore, after the brake moving member is pulled by the brake wire, the compression spring can push the brake moving member back to its original position by its resilience.

[0027] During braking, the brake wire is pulled. The movement of the brake wire drives the pull rod, causing the pull rod to move along the positioning sleeve. The movement of the pull rod drives the brake moving member. By the inward squeezing of the brake moving member on the flow guiding portion, the brake seat can be driven to move inward synchronously along the sliding groove, so as to achieve the effect of double braking.

[0028] Among them, the movement of the brake seat drives the first brake pad and the second brake pad. The first brake pad can contact the outer circumferential surface of the brake disc, and the first brake surface on the second brake pad can contact the second brake surface on the brake disc, so that the brake seat can contact the outer circumference and both sides of the brake disc, greatly increasing the contact area during braking, ensuring the quality of braking, avoiding the situation of slipping and being unable to brake, and increasing the safety of using the electric vehicle.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
