[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 10 As shown, the utility model provides a built-in electric vehicle brake power-off switch, comprising a housing 1 and a handle body 2. A power-off switch body 3 is provided inside the housing 1, a contact 4 is provided on one side of the power-off switch body 3, and a handle protrusion 16 located inside the housing 1 is fixedly mounted on one side of the handle body 2.

[0032] A protective mechanism is arranged inside the shell 1. The protective mechanism includes a spring 5, which is fixedly connected to the inside of the shell 1. Two protective shells 6 are fixedly installed on one end of the spring 5 close to the surface of the contact 4. A connecting sleeve 11 is provided on the opposite side of the two protective shells 6. Two hinge blocks 7 are fixedly installed on the outer surfaces of the two protective shells 6. Two hinge rods 8 are hinged inside the two hinge blocks 7. The ends of the two hinge rods 8 close to the surface of the contact 4 are hinged through hinge block 2 9. A pulling belt 10 is fixedly installed on one side of the hinge block 2 9. One end of the pulling belt 10 is fixedly connected to one side of the handle body 2.

[0033] With the above solution, the operator fixes the housing 1 on the handlebar. When braking is required, the operator can hold the handle body 2 and pull the handle body 2 to rotate. The handle body 2 will drive the handle protrusion 16 to rotate. During the rotation of the handle protrusion 16, it will move away from the surface of the contact 4, and then the power-off switch body 3 will start to be energized. Then, the electric vehicle controller receives the signal and the motor stops working, thereby achieving the purpose of braking.

[0034] When the handle protrusion 16 rotates away from the surface of the contact 4, it will pull the pulling belt 10, and the pulling belt 10 will pull the hinge block 2 9 to move. Since one end of the two hinged rods 8 is hinged through the hinge block 2 9, the hinge block 2 9 will pull the hinge rod 8 to rotate, and the rotating hinge rod 8 will pull the hinge block 1 7 toward the surface of the contact 4. The hinge block 1 7 will drive the protective shell 6 and the connecting sleeve 11 to move toward the surface of the contact 4. When the protective shell 6 moves, the spring 5 will be stretched, and then the surface of the connecting sleeve 11 will contact the surface of the contact 4, thereby protecting the contact 4. Finally, the rotating handle protrusion 16 pulls the pulling belt 10 so that the connecting sleeve 11 wraps around the contact 4, thereby being able to resist mechanical shock and vibration, protect the contacts from accidental damage, and extend the service life of the power off switch body.

[0035] When the handle body 2 is released, the handle body 2 will be reset, and then the stretched spring 5 will pull the protective shell 6 and the connecting sleeve 11 to reset, thereby moving away from the surface of the contact 4.

[0036] like Figure 6 and Figure 7 As shown, two limiting rods 12 are fixedly installed in the inner cavity of the shell 1, and two limiting blocks 13 are slidably connected to the surfaces of the two limiting rods 12. One side of the two limiting blocks 13 is fixedly connected to one side of the two protective shells 6.

[0037] Adopting the above solution: through the design of the limit rod 12 and the limit block 13, when the protective shell 6 moves, the limit block 13 will be driven to move on the surface of the limit rod 12, and then the limit rod 12 can limit the limit block 13 and the protective shell 6, thereby increasing the stability of the movement of the protective shell 6.

[0038] like Figure 7 and Figure 10 As shown, the internal rotation of the shell 1 is connected to a rotating rod 14, and the pulling belt 10 is wrapped around the surface of the rotating rod 14. The power-off switch body 3 and the shell 1 are fixed by fixing bolts 15. There are two fixing bolts 15, and the array part is connected to the inside of the shell 1.

[0039] The above solution is adopted: through the design of the rotating rod 14, since the pulling belt 10 is wrapped around the surface of the rotating rod 14, when the pulling belt 10 moves, the moving pulling belt 10 will drive the rotating rod 14 to rotate through its friction force. Through the rotation of the rotating rod 14, the pulling belt 10 can be made to move more smoothly, and the moving trajectory of the pulling belt 10 can be limited. Through the design of the fixing bolt 15, the fixing bolt 15 can be used, and then the power-off switch body 3 is fixed inside the shell 1, so that it is not easy to age and will not be disturbed by external forces. The number of fixing bolts 15 is two, which can increase its fixing effect.

[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 9 As shown, a mounting groove 20 is provided on one side of the power off switch body 3, and a cable is provided inside the mounting groove 20. A sealing plate 17 located on one side of the handle body 2 is fixedly installed on one side of the housing 1, and the sealing plate 17 is made of rubber material.

[0041] Adopting the above-mentioned scheme: through the design of the installation groove 20, the cable can be set inside the installation groove 20, and silicone can be encapsulated through the welding point, thereby improving the overall waterproof performance. Through the design of the sealing plate 17, when the handle body 2 rotates, the sealing plate 17 can seal the gap between the shell 1 and the handle body 2, thereby preventing rainwater or other impurities from entering the interior of the shell 1 along the gap between the shell 1 and the handle body 2 when the handle body 2 rotates, thereby affecting the normal operation of the contact 4.

[0042] like Figure 3 、 Figure 5 and Figure 7 As shown, a pin shaft 18 is provided inside the shell 1, and the handle body 2 can rotate on the surface of the hinge rod 8. A retaining spring 19 is provided on one side of the surface of the pin shaft 18. There are four springs 5, and the springs 5 ​​are distributed in an array inside the shell 1.

[0043] The above solution is adopted: through the design of the pin 18 and the retaining spring 19, when the handle body 2 rotates, it can rotate along the pin 18, and the pin 18 can be limited, and a retaining spring 19 is provided on one side of the surface of the pin 18, so that the pin 18 can be fixed. Through the design of the spring 5, since there are four springs 5 ​​and the array part is inside the shell 1, when the protective shell 6 is reset, the spring 5 can stably pull the protective shell 6 to move inside the shell 1.

[0044] like Figure 5 、 Figure 6 and Figure 7 As shown, the connecting sleeve 11 is designed to be arc-shaped and made of rubber material, the limiting rod 12 and the limiting block 13 are designed to be longitudinally symmetrical about the center of the shell 1, and the surface of the limiting rod 12 is designed to be smooth.

[0045] The above-mentioned solution is adopted: through the design of the connecting sleeve 11, since the connecting sleeve 11 is an arc-shaped design, the connecting sleeve 11 can be fully fitted with the contact 4, and the connecting sleeve 11 is made of rubber material. Since the rubber material has good wear resistance and insulation, the risk of electric shock is avoided, and it can resist wear and friction during long-term use, thereby extending the service life of the brake handle. Through the design of the limit rod 12 and the limit block 13, since the limit rod 12 and the limit block 13 are symmetrically designed, the two limit rods 12 can limit the protective shell 6, and the limit rod 12 is smooth in design, which can make the limit block 13 move more smoothly.

[0046] The working principle and use process of this utility model:

[0047] First, the operator fixes the housing 1 and the handle body 2 on the surface of the handlebar. When riding and braking is required, the handle body 2 and the handle protrusion 16 can be rotated. The handle protrusion 16 will move away from the surface of the contact 4, and then the power-off switch body 3 will start to energize. Then, the electric vehicle controller receives the signal and the motor stops working, achieving the purpose of braking.

[0048] When the handle protrusion 16 rotates, it will pull the pulling belt 10 to move. When the pulling belt 10 moves, it will drive the rotating rod 14 to rotate, so that the pulling belt 10 moves more smoothly. Then the pulling belt 10 will pull the hinge block 2 9 to move, and the hinge block 2 9 will drive the hinge rod 8 to rotate. The hinge rod 8 will pull the hinge block 1 7, the protective shell 6 and the connecting sleeve 11 toward the surface of the contact 4. When the protective shell 6 moves, the spring 5 will be stretched, and then the surface of the connecting sleeve 11 will contact the surface of the contact 4, thereby protecting the contact 4 and finally completing the operation process.
