technical field

The invention relates to the field of electric vehicle production and manufacturing, and more specifically, the invention relates to a bidirectionally rotatable electric vehicle handle.

Background technique

At present, a device that uses a two-way handle to control the acceleration and braking of a vehicle uses electronic accelerator and electronic brakes to realize the rotation of the two-way handle to control the acceleration and braking of electric vehicles, but this method cannot be directly transplanted to most existing electric vehicles. In fact, because most of the existing electric vehicles use mechanical brakes, if this solution is required, a power source device for the braking system must be equipped, which will increase the size and cost of the electric vehicle.

Contents of the invention

The purpose of the present invention is to solve the existing above-mentioned problems, and to provide a bidirectionally rotatable electric vehicle handlebar.

In order to achieve the above objectives, the technical solution of the present invention is a bidirectionally rotatable handlebar for an electric vehicle, including a handlebar seat and an inner liner, characterized in that a brake shaft is provided between the inner liner and the handlebar seat, so The above-mentioned brake shaft is bonded to the inner liner and the handle seat, the above-mentioned brake shaft is provided with a rotating block, and the above-mentioned rotating block is fixedly connected with the brake shaft, and the above-mentioned inner lining is provided with a corresponding rotating block. The bump is fixedly connected with the lining. When the inner liner rotates forward, the electric vehicle is driven by the interaction between the inner liner and the handle seat. When the inner liner is reversed, the bump on the inner liner drives the rotating block on the brake shaft, thereby driving the brake through the brake shaft. The handlebar integrates acceleration and braking functions at the same time, which reduces the time for electric vehicles to switch between acceleration and braking states, and can be directly transplanted to existing electric vehicles.

Preferably, one end of the brake shaft is provided with a brake card slot. The brake card slot on the brake shaft is for the zinc head on the end of the brake post brake cable.

Preferably, the end of the brake slot on the brake shaft is provided with a brake cable slot corresponding to the brake slot. The brake line groove is used for the installation and positioning of the brake line to prevent the wear of the brake line during braking.

As a preference, a magnetic steel sheet is provided on the bump, and the magnetic steel sheet is fixedly connected with the bump, and a Hall element corresponding to the magnetic steel sheet is provided on the handlebar seat. The Hall element is fixedly connected with the handlebar. The mutual position of the magnetic steel sheet on the bump and the Hall element changes, and the Hall element sends out a signal to drive the vehicle.

Preferably, a limit block is provided on the handle base, and the limit block is fixedly connected with the handle base. When the vehicle is driven, the limit block acts as a limit to prevent the brake shaft from rotating.

Preferably, the diameter of the inner liner is larger than that of the brake shaft. The diameter of the inner liner is larger than the diameter of the brake shaft, which reduces the torque required by the driver to turn the handle when braking.

Preferably, a return spring is provided between the rotating block and the inner liner, and both ends of the return spring are fixedly connected to the rotating block and the inner liner. When the vehicle is driven or braked, the return spring plays a reset role.

Preferably, the rotating block is provided with a first positioning hole, the inner lining is provided with a second positioning hole, and the two ends of the return spring are respectively arranged in the first positioning hole and the second positioning hole . The first positioning hole and the second positioning hole are used for fixing the return spring.

Preferably, a bearing is sleeved on the outside of the brake shaft, and the outer ring of the bearing is fixedly connected to the inner lining. Bearings reduce friction and reduce the forces exerted on the driver when driving the vehicle.

Preferably, the rotating block and the protruding block are fan-shaped, and the angle of the fan-shape is 30°-60°. In this way, the strength of the rotating block and the protruding block can be guaranteed while ensuring the normal operation of the rotating block and the protruding block.

The invention has the following beneficial effects: simple structure, when the inner lining of the handle turns inward, the relative position between the magnetic steel sheet and the Hall element changes, and the Hall element sends out a rotation signal of the handle to drive the vehicle, and the inner lining of the handle turns outward At the same time, the brake shaft also rotates outward; the brake shaft rotates the brake line, thereby braking the vehicle; the handlebar integrates acceleration and braking functions at the same time, reducing the time for electric vehicle acceleration and braking state switching, and can be directly transplanted to existing electric vehicles.
