Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, specifically to an electric scooter with dual braking function. Background Technology

[0002] With the increasing severity of urban traffic congestion and the growing demand for environmentally friendly travel options, electric scooters have become a popular and convenient low-carbon mode of urban transportation. Currently, most electric scooters typically have the front wheel as the drive wheel and integrate a hub motor inside the front wheel.

[0003] However, most electric scooters currently on the market use a single front-wheel braking mechanism to slow down or stop the vehicle. When the user applies the brakes, the vehicle is stopped only by the front wheel's braking device. While this method can meet basic braking needs under normal circumstances, if the front wheel's braking assembly malfunctions or fails, the entire vehicle will lose its effective braking ability, leading to serious safety hazards. Furthermore, relying solely on front-wheel braking can easily cause uneven distribution of braking force between the front and rear wheels, affecting vehicle stability, especially on wet and slippery surfaces, making skidding more likely.

The controller 22 controls the hub motor 13 of the front drive wheel 12 to stop working quickly, preventing the front drive wheel 12 from continuing to accelerate. In addition, by setting a front brake assembly and a front brake cable 44, the user can press the front brake handle 42, which drives the front brake assembly through the front brake cable 44, causing the front drive wheel 12 to stop rotating quickly. At the same time, by setting a rear brake assembly and a rear brake cable 45, the user can press the rear brake handle 43, which drives the rear brake assembly through the rear brake cable 45, causing the rear drive wheel to stop rotating quickly.

[0033] This embodiment integrates an electronic brake switch 41, a front brake assembly, and a rear brake assembly, enabling users to brake in multiple ways. This effectively prevents the inability to brake if one braking method fails, thus enhancing safety performance. Additionally, braking can be performed simultaneously, allowing the electric scooter to brake quickly.

[0034] This embodiment describes an electric scooter with dual braking function. The front drive wheel 12 is equipped with a hub motor 13. Both ends of the hub motor 13 are detachably connected to the front connecting seat 11. The hub motor 13 is electrically connected to the controller 22 via wires. With this configuration, the user can rotate the bicycle handlebars, thereby driving the hub motor 13 through the controller 22, causing the front drive wheel 12 to rotate.

[0035] The electric scooter with dual braking function described in this embodiment includes a front brake assembly comprising a front brake disc 51 coaxially driven with the front drive wheel 12 and a front brake caliper 52 detachably connected to the front connecting seat 11; one end of the front brake cable 44 is connected to the front brake grip 42; the other end of the front brake cable 44 passes through the handle seat 4, the front bar 1 and the front connecting seat 11 in sequence and is connected to the front brake caliper 52.

[0036] Specifically, when braking is required, the user presses the front brake lever 42, which drives the front brake caliper 52 through the front brake cable 44, thereby stopping the front brake disc 51 from rotating, and thus stopping the front drive wheel 12 from rotating. In this embodiment, the front brake cable 44 is threaded between the handlebar seat 4, the front lever 1, and the front connecting seat 11, preventing the front brake cable 44 from being directly exposed to the outside, thus protecting the front brake cable 44 and making the overall structure neater and more aesthetically pleasing.
