Description

Technical Field

[0001] This utility model relates to the field of anti-interference speed control throttle for electric vehicles, and more specifically, to an anti-interference speed control throttle for electric vehicles. Background Technology

[0002] Currently, the principle of speed control throttles is mainly based on the Hall effect and magnetic field changes. A speed control throttle typically consists of components such as a magnet, a Hall element, a return spring, sensing circuitry, and a plastic housing. When the user turns the throttle, the position of the internal magnet changes, causing a change in the magnetic field strength. The Hall element detects this change in magnetic field and outputs a corresponding electrical signal. This electrical signal is proportional to the change in magnetic field strength, hence it is called a linear Hall signal. The sensing circuitry transmits this signal to the controller, which determines the electric bicycle's speed and direction based on the received signal and adjusts the motor's speed and direction accordingly. Specifically, when the user turns on the electric bicycle, the Hall element receives a 5V power supply. When the user turns the throttle, the change in the internal magnet's position increases the magnetic field strength, and the Hall element, sensing this change, outputs a voltage ranging from 1 to 4.2V. The controller receives this voltage signal, compares it with a set threshold, and outputs a corresponding voltage value to drive the motor, thus regulating the speed. The construction of a speed control throttle includes a magnet, a Hall element, a return spring, sensing circuitry, and a plastic housing. The magnet senses the speed signal through the magnetic field and sends it to the controller; the Hall element detects changes in the magnetic field and transmits an electrical signal to the controller; the return spring ensures the throttle returns to the neutral position; the sensing circuit converts the position information into an electrical signal and transmits it to the controller; the plastic shell protects the internal components; most electric vehicles use Hall effect throttles, which work by using the Hall effect, where current passing through a magnetic field generates an induced electromotive force that causes a voltage change; therefore, they have poor electromagnetic interference resistance. If they are disturbed by other magnetic fields or other factors while riding, there may be abnormal output voltage, causing the electric vehicle to be out of control by the throttle, which can easily pose a serious safety hazard to the rider;

[0003] In the prior art, application publication number CN112009609A discloses an electric vehicle throttle handle, including a steering handle, a rotating handle, and a speed adjustment mechanism. The speed adjustment mechanism includes a housing, a sensing component, a shielding component, and a reset component. The reset component and the sensing component are disposed inside the housing. The left end of the rotating handle extends into the housing and is rotatably connected to the speed adjustment mechanism. A magnet is provided on the left end face of the rotating handle. The shielding component is disposed outside the sensing component, and has an opening facing the magnet, through which the sensing component senses the magnetic field of the magnet. The free end of the reset component is connected to the rotating handle, and the reset component provides elastic force to the rotating handle and resets the rotating handle. The speed adjustment mechanism is disposed near the right end of the steering handle, and the rotating handle is sleeved on the outside of the right end of the steering handle. In this invention, a shielding component is provided outside the sensing component, which enhances the ability to resist magnetic field interference and avoids the magnetic field of the speed adjustment mechanism from being interfered with by the external environment, thus preventing the electric vehicle from being controlled by the throttle handle.

[0004] The aforementioned patent includes a shielding component structure that uses an iron sheet to shield against external magnetism. However, the iron sheet is exposed on the handlebars, making it prone to rusting and inconvenient to install. Utility Model Content
