Description

Technical Field

[0001] This invention relates to the field of electric scooter technology, and particularly to an electric scooter with dual brakes. Background Technology

[0002] Electric scooters, as a modern urban transportation tool, combine convenience, environmental friendliness, and economy, and are gradually becoming an important part of people's daily lives; they can provide a convenient and fast way to commute in the city; electric scooters have significant advantages in urban commuting and short-distance travel: convenience, environmental friendliness, economy, health, and entertainment.

[0003] Existing electric scooters typically use a handbrake, meaning the braking mechanism is located in front of the handlebars. This mechanism has a long transmission chain and can be either a front brake or a rear brake. At high speeds, the front brake can easily cause tipping. Furthermore, users often mistakenly identify the front brake and the handbrake, leading to incorrect braking. The rear brake, on the other hand, is the most frequently used braking method and ensures user safety. To prevent incorrect braking, this invention proposes an electric scooter with a brake mechanism located at the rear of the scooter, utilizing a foot pedal for braking. This avoids the errors caused by manual braking and improves user safety. Summary of the Invention

A brake mounting part 27 is deflected on the brake slide 23. A brake pad 28 is provided on the brake mounting part 27. When the brake pedal 6 is pressed, the linkage slide 18 moves and pushes the brake slide 23 so that the brake pad 28 contacts the brake disc 13 to complete the braking.

[0029] The foot brake mechanism includes a brake mounting box 9 located at the rear end of the base 1. One end of the brake pedal 6 is rotatably mounted inside the brake mounting box 9, and a torsion spring 10 is connected between the brake pedal 6 and the brake mounting box 9 to provide reset torque. A sensing magnet 32 ​​is provided on the linkage slide 18, and a Hall effect sensor 33 is provided on the base 1 and below the sensing magnet 32. The Hall effect sensor 33 detects the position of the sensing magnet 32 ​​to control the power output of the front wheel 3 and perform electronic assisted braking.

[0030] A connecting seat 22 is provided at the rear end of the base 1. A guide rod 21 is connected between the connecting seat 22 and the mounting bracket 8. A guide rod 20 is provided at the top of the connecting seat 22. The guide rod 20 is slidably connected to the linkage slide 18. A spring 19 is connected between the linkage slide 18 and the end of the guide rod 20 to provide elastic force. A push wheel 17 is provided at the bottom of the linkage slide 18. The push wheel 17 pushes the inclined push plate 24 to move the brake slide 23. The brake slide 23 is slidably mounted. A spring 25 for providing elastic force is connected between the brake slide 23 and the connecting seat 22 and mounted on the guide rod 21. A lead screw motor 29 and a lead screw 31 are provided on the brake slide 23. The lead screw motor 29 is used to drive the lead screw 31. A lead screw slide 30 is slidably mounted on the brake slide 23. The lead screw slide 30 and the lead screw 31 form a helical pair. A deflection connecting rod 26 is rotatably mounted on the lead screw slide 30. One end of the deflection connecting rod 26 is rotatably connected to the brake mounting part 27.

[0031] An emergency braking cylinder 16 is provided at the rear end of the base 1. An emergency push plate 15 is provided on the telescopic rod of the emergency braking cylinder 16. The emergency braking cylinder 16 controls the emergency push plate 15 to push the linkage slide 18 to perform emergency braking. A protective box 7 is provided on the mounting frame 8. A control electric cylinder 12 is provided inside the protective box 7. A cleaning part 11 is provided on the telescopic rod of the control electric cylinder 12. The cleaning part 11 is used to perform maintenance on the brake disc 13.

[0032] When implementing this invention: In this embodiment, foot braking is possible. Specifically, the brake pedal 6 is pressed with the foot, causing it to deflect and the torsion spring 10 to twist, providing a reset torque. When the brake pedal 6 rotates, the linkage slide 18 moves under the connection of the linkage rod 14, compressing the spring 19 and providing a reset elastic force. When the linkage slide 18 moves, the push wheel 17 pushes the inclined push plate 24, causing the brake slide 23 to move. That is, the brake slide 23 and the inclined push plate 24 move towards the brake disc 13, and the brake pad 28 and the brake disc... When plate 13 contacts, braking is completed. Further, when the linkage slide 18 moves, the sensing magnet 32 ​​moves, and the Hall detection sensor 33 detects the position of the sensing magnet 32 ​​and issues a command to control the power output, that is, to control the power motor 5 to interrupt the power output, thus assisting the electronic brake. In case of emergency braking, such as when the vehicle system detects an obstacle or pedestrian in front and there is no braking deceleration, the emergency brake cylinder 16 controls the emergency push plate 15 to push the linkage slide 18 to perform emergency braking. The control process of emergency braking is existing technology and will not be described in detail here.

[0033] During subsequent maintenance, such as replacing brake pads 28, the lead screw motor 29 can be activated, causing the lead screw 31 to rotate and the lead screw slide 30 to slide. Under the connection of the deflection linkage 26, the brake mounting part 27 is deflected outward, exposing the brake pads 28 to the outside, making it easier to replace the brake pads 28. Furthermore, when maintaining the brake disc 13, if there is oil on the surface of the brake disc 13, which may cause the brakes to become unresponsive, the cleaning part 11 can be controlled by the control cylinder 12 to wipe away the oil, achieving the purpose of cleaning and maintenance.
