Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a bidirectional rotating handlebar structure and an electric vehicle using the bidirectional rotating handlebar structure. Background Technology

[0002] The existing two-wheeled electric vehicle handlebar control methods are relatively traditional and simplistic, with many shortcomings. On the one hand, when an electric vehicle needs to decelerate or stop, relying solely on mechanical braking not only leads to a waste of vehicle kinetic energy, but frequent use of the brakes may also cause the braking system to wear out too quickly and the braking effect to gradually deteriorate, affecting driving safety. On the other hand, for reversing operations, it is often necessary to set up a separate reversing control button or device, which is not convenient to operate and cannot quickly and easily realize the reversing function, greatly affecting the user's driving experience and the flexibility of vehicle use. Utility Model Content

[0003] The purpose of this utility model is to provide a bidirectional rotating handlebar structure and an electric vehicle using the bidirectional rotating handlebar structure, which enables forward driving, braking and reversing operations by rotating the handlebar in both directions.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a bidirectional rotating handle structure, including a grip and a mounting base. The grip is rotatably connected to the mounting base around its central axis. A first Hall element and a second Hall element are spaced apart along the outer periphery of the grip in the mounting base. A magnet is provided on the grip and can rotate synchronously with the grip. In the initial position of the grip, the magnet is located between the first Hall element and the second Hall element. When the grip is rotated in a first direction, the magnet shifts towards the position of the first Hall element. When the grip is rotated in a second direction, the magnet shifts towards the position of the second Hall element. The first Hall element is configured to be connected to the power system of the electric vehicle. The second Hall element is configured to be connected to both the power system and the kinetic energy recovery system of the electric vehicle.

[0006] Preferably, the end of the handle facing the mounting base is provided with an extension, which is an arc-shaped ring around the central axis of the handle. A receiving groove is provided on the outer peripheral surface of the extension, and the magnet is placed in the receiving groove.

[0007] Preferably, a stop block is fixedly provided in the mounting base, and when the handle is rotated to the maximum working angle in the first direction, the extension abuts against the stop block.

[0008] Preferably, the mounting base is provided with a first elastic element, the two ends of which are connected to the handle and the mounting base respectively. When the handle is rotated in the first direction, the first elastic element deforms and accumulates a restoring force that drives the handle back to the initial position.

[0009] Preferably, the first elastic element is a return spring, and the central axis of the return spring is parallel to the central axis of the grip.

[0010] Preferably, the mounting base is provided with a second elastic element, the two ends of which are connected to the handle and the mounting base respectively. When the handle is rotated in the second direction, the second elastic element deforms and accumulates a restoring force that drives the handle back to the initial position.

[0011] Preferably, the mounting base is provided with a guide block, which can slide circumferentially around the central axis of the mounting base, and the two ends of the guide block along the sliding direction are respectively connected to the handle and the second elastic element.

[0012] Preferably, the mounting base is also provided with a sound generator, which is triggered when the handle is rotated to the maximum working angle in the second direction.

[0013] This utility model also provides an electric vehicle, including the bidirectional rotating handlebar structure described above.

[0014] Compared with the prior art, this utility model has significant progress:

[0015] This invention features a bidirectional rotating handle structure that controls vehicle movement by rotating the handle. When accelerating forward, rotating the handle in the first direction shifts the magnet towards the first Hall element, increasing the magnetic field sensed by the element. Based on the Hall effect, the first Hall element outputs a higher voltage, which is transmitted to the power system via a signal line. The power system then adjusts the motor parameters, causing the vehicle to accelerate forward. When decelerating, rotating the handle in the second direction shifts the magnet towards the second Hall element, increasing the magnetic field sensed by the element. Based on the Hall effect, the second Hall element outputs a higher voltage, which first activates the kinetic energy recovery system via a signal line. The vehicle decelerates smoothly, recovering energy and converting it into stored electrical energy. After the vehicle stops, the signal is transmitted back to the power system, causing the motor to rotate in the opposite direction to reverse. By activating the kinetic energy recovery system by rotating the handle, potentially wasted kinetic energy is converted into electrical energy for storage and reuse during deceleration or braking, effectively improving the vehicle's energy efficiency, extending its range, and reducing reliance on and frequency of battery replacement. Precise acceleration and deceleration control helps users better cope with various complex road conditions and avoid the risk of accidents caused by excessive or insufficient speed. Assisted braking reduces the frequency of mechanical brake use, lowers the probability of wear and tear and malfunctions caused by frequent friction in the braking system, and improves the reliability and safety of the vehicle's braking system.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0023] like Figures 1 to 4 The image shows one embodiment of the bidirectional rotating handle structure provided by this utility model.

[0024] See Figures 1 to 4The bidirectional rotating handle structure of this embodiment includes a grip 1 and a mounting base 2. The grip 1 is rotatably connected to the mounting base 2 around its central axis. A first Hall element 3 and a second Hall element 4 are spaced apart along the outer periphery of the grip 1 in the mounting base 2. A magnet 5 is provided on the grip 1 and can rotate synchronously with the grip 1. In the initial position of the grip 1, the magnet 5 is located between the first Hall element 3 and the second Hall element 4. The grip 1 is made of high-strength, wear-resistant engineering plastic material, and its outer surface is provided with anti-slip grooves, ensuring both service life and improved user comfort and safety. The mounting base 2 is manufactured using high-precision processing technology to improve its stability and accuracy retention during long-term use. After detecting a change in magnetic field strength, the first Hall element 3 and the second Hall element 4 convert the change into a corresponding electrical signal output according to the Hall effect principle. Specifically, when the magnetic field strength increases, the voltage signal output by the Hall element increases; when the magnetic field strength decreases, the voltage signal output by the Hall element decreases. The magnet 5 has undergone rigorous magnetic performance testing and dimensional precision control to ensure the stability of the magnetic field strength of the magnet 5 during the rotation of the handle 1 and its compatibility with the Hall element.

[0025] The first Hall element 3 is configured to be connected to the electric vehicle's power system signal. When the handlebar 1 is rotated in the first direction, the magnet 5 shifts towards the position of the first Hall element 3. At this time, the magnetic field strength detected by the first Hall element 3 gradually increases. According to the Hall effect, the voltage signal output by the first Hall element 3 increases. The enhanced voltage signal output by the first Hall element 3 is transmitted to the electric vehicle's power system through the signal connection line. After receiving the signal, the power system adjusts the motor control parameters according to a preset control algorithm, thereby increasing the motor speed. The increase in motor speed causes the drive wheels of the electric vehicle to rotate faster, thus accelerating the electric vehicle forward.

[0026] The second Hall element 4 is configured to be signal-connected to both the electric vehicle's power system and kinetic energy recovery system. When the handlebar 1 is rotated in the second direction, the magnet 5 shifts towards the position of the second Hall element 4. At this time, the magnetic field strength detected by the second Hall element 4 gradually increases, and according to the Hall effect, the voltage signal output by the second Hall element 4 increases. The enhanced voltage signal output by the second Hall element 4 is first transmitted to the electric vehicle's kinetic energy recovery system through the signal connection line. After receiving this enhanced voltage signal, the kinetic energy recovery system is activated and begins to work. The kinetic energy recovery system absorbs the kinetic energy released by the electric vehicle during deceleration and converts it into electrical energy, which is stored for later use. At the same time, the vehicle's speed gradually decreases, and the entire braking process is smooth without violent impacts or bumps, allowing the electric vehicle to gradually and smoothly come to a stop. When the electric vehicle comes to a complete stop, the voltage signal output by the second Hall element 4 is transmitted to the power system through the signal connection line. After receiving this signal, the power system's internal control unit begins to process the signal. The control unit precisely adjusts the motor's control parameters according to a preset control algorithm. Specifically, the control unit changes the current direction or phase in the motor drive circuit, causing the motor to rotate in the opposite direction. When the motor rotates in the reverse direction, the drive wheels of the electric vehicle also rotate in the reverse direction, thus realizing the reversing function of the electric vehicle.

[0027] Therefore, the bidirectional rotary handle structure of this embodiment controls the vehicle's driving state by rotating the handle 1. When accelerating forward, rotating the handle 1 in the first direction causes the magnet 5 to shift towards the first Hall element 3. The magnetic field sensed by the first Hall element 3 increases, and according to the Hall effect, the output voltage of the first Hall element 3 rises. The increased voltage is transmitted to the power system via a signal line, and the power system adjusts the motor parameters to accelerate the vehicle forward. When decelerating, rotating the handle 1 in the second direction causes the magnet 5 to shift towards the second Hall element 4. The magnetic field sensed by the second Hall element 4 increases, and according to the Hall effect, the output voltage of the second Hall element 4 rises. The increased voltage is transmitted to the signal line to first activate the kinetic energy recovery system, allowing the vehicle to decelerate smoothly. Energy is recovered and converted into electrical energy for storage. After the vehicle stops, the signal is transmitted to the power system again, and the motor rotates in the opposite direction to achieve reversing. By rotating the handle 1 to activate the kinetic energy recovery system, kinetic energy that might otherwise be wasted is converted into electrical energy and stored for reuse during vehicle deceleration or braking. This effectively improves the vehicle's energy utilization efficiency, extends the vehicle's range, and reduces dependence on and frequency of battery replacement. Precise acceleration and deceleration control helps users better cope with various complex road conditions and avoid the risk of accidents caused by excessive or insufficient speed. The auxiliary braking effect reduces the frequency of mechanical brake use, lowers the wear and tear and probability of malfunction caused by frequent friction in the braking system, and improves the reliability and safety of the vehicle's braking system. The bidirectional rotary handle structure in this embodiment integrates acceleration, deceleration, energy recovery, and reversing functions into one unit. Users can control various driving states of the vehicle simply by rotating the handle 1, eliminating the need to operate multiple independent control components, simplifying the operation process and improving driving convenience and comfort.

[0028] See Figures 2 to 4 Preferably, the handle 1 has an extension 11 at the end facing the mounting base 2. The extension 11 is an arc-shaped ring around the central axis of the handle 1, and a receiving groove 111 is formed on the outer circumferential surface of the extension 11, in which the magnet 5 is placed. The extension 11 is integrally formed with the handle 1, and the shape of the extension 11 matches the mounting base 2, allowing the handle 1 to rotate smoothly around the central axis of the mounting base 2. The size of the receiving groove 111 matches the magnet 5, providing precise positioning and a secure mounting position for the magnet 5, effectively preventing displacement or loosening of the magnet 5 during the rotation of the handle 1. When the handle 1 rotates in different directions, the extension 11 rotates synchronously, and the magnet 5 shifts synchronously within the receiving groove 111, changing its relative position with the Hall element, thereby causing a change in the magnetic field strength. After detecting the change in magnetic field strength, the Hall element converts the change in magnetic field strength into a corresponding electrical signal output according to the Hall effect principle, realizing the control of the electric vehicle's driving state.

[0029] See Figure 4Preferably, in order to precisely control the rotation range of the handle 1 and prevent it from over-rotating, a stop block 21 is fixedly provided in the mounting base 2. When the handle 1 is rotated to the maximum working angle in the first direction, the extension 11 abuts against the stop block 21. By setting the stop block 21, it can be ensured that the handle 1 will not continue to rotate when it reaches the maximum working angle, thereby avoiding mechanical damage or control failure due to over-rotation. This improves the reliability and stability of the bidirectional rotary handle structure of this embodiment, and also provides clear tactile feedback to the user, allowing the user to intuitively feel the rotation range limitation of the handle 1 during operation.

[0030] See Figure 2 and Figure 3 Preferably, the mounting base 2 is provided with a first elastic element 6. The two ends of the first elastic element 6 are connected to the grip 1 and the mounting base 2, respectively. When the grip 1 is rotated in the first direction, the first elastic element 6 deforms and accumulates a restoring force that drives the grip 1 back to its initial position. In this embodiment, the first elastic element 6 is a return spring, and the central axis of the return spring is parallel to the central axis of the grip 1. When the grip 1 is rotated in the first direction, the end of the return spring connected to the grip 1 rotates synchronously with the grip 1, causing the return spring to deform in the radial direction, thereby accumulating elastic potential energy. As the grip 1 continues to rotate, the deformation of the return spring gradually increases. When the user releases the grip 1, the return spring, with the help of its accumulated elastic potential energy, can quickly and smoothly pull the grip 1 back to its initial position, thus ensuring that the grip 1 can return to its initial position quickly and accurately. Furthermore, it provides a smooth and uniform return force throughout the process, reducing interference with the user's operation and improving driving comfort and safety.

[0031] See Figure 2 and Figure 3 Preferably, the mounting base 2 is provided with a second elastic element 7. The two ends of the second elastic element 7 are connected to the handle 1 and the mounting base 2, respectively. When the handle 1 is rotated in the second direction, the second elastic element 7 deforms and accumulates a restoring force that drives the handle 1 back to its initial position. In this embodiment, the second elastic element 7 is a spring arranged circumferentially around the mounting base 2. When the handle 1 is rotated in the second direction, the spring is gradually compressed under the push of the handle 1. As the rotation angle of the handle 1 increases, the degree of spring compression also increases, and more elastic potential energy is accumulated. When the user releases the handle 1, the spring releases its stored elastic potential energy, generating a restoring torque opposite to the second direction, thereby driving the handle 1 to smoothly return to its initial position. Furthermore, by reasonably selecting the spring stiffness coefficient and preload, the magnitude of the return force of the handle 1 can be precisely adjusted to adapt to different users' operating habits and driving needs, further optimizing the user's driving experience.

[0032] See Figure 2 and Figure 3Preferably, the mounting base 2 is provided with a guide block 22, which can slide circumferentially around the central axis of the mounting base 2. The two ends of the guide block 22 along the sliding direction are respectively connected to the handle 1 and the second elastic element 7. In this embodiment, the second elastic element 7 is a spring. When the handle 1 is rotated along the second direction, the extension 11 of the handle 1 pushes the guide block 22, causing the guide block 22 to slide circumferentially in the mounting base 2 and compress the spring. The sliding and pushing action of the guide block 22 ensures stable force transmission, allowing the spring to deform uniformly under force and effectively accumulate energy. When it is necessary to return to its original position, the spring releases energy, and the guide block 22 smoothly pushes the extension 11 of the handle 1 back to its initial position. Furthermore, the end of the guide block 22 that connects to the spring has a cylindrical protrusion, and the spring is sleeved on the cylindrical protrusion of the guide block 22, thereby ensuring stable engagement between the guide block 22 and the spring during the rotation of the handle 1.

[0033] See Figure 2 and Figure 3 Preferably, the mounting base 2 is also equipped with a sound generator 8. When the handle 1 is rotated to its maximum working angle in the second direction, the handle 1 triggers the sound generator 8. In this embodiment, when the handle 1 reaches its maximum working angle in the second direction, the extension 11 of the handle 1 pushes the guide block 22 to press the button switch on the sound generator 8, causing the sound generator 8 to emit a prompt sound. Thus, the user can receive timely audible prompts during operation, knowing that the handle 1 has reached its maximum working angle, thereby avoiding mechanical damage or control failure that may result from excessive rotation. Through the prompt sound of the sound generator 8, the user can more accurately control the rotation range of the handle 1, ensuring the safety and stability of operation.
