[0045] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0046] Example

[0047] In this embodiment, directional terms such as left and right are used only for ease of explanation and are not intended to limit the meaning of the terms.

[0048] See Figures 1 to 6 As shown, an electric vehicle handlebar structure includes a throttle core 1, an acceleration control structure 2, and a connector 3. The acceleration control structure is connected to the end of the throttle core via the connector. In this embodiment, the throttle core is a conventional structure of the prior art, so it is not described in detail, but simply applied. Specifically, it is used on the Xiaomi Ninebot electric vehicle. In actual use, the outer side of the throttle core will have a rubber sleeve. The connector can be a plastic structure or a metal structure. Specifically, the connector 3 includes a left semi-circular ring 31 and a right semi-circular ring 32 fixed by screws. The acceleration control structure is located between the left semi-circular ring 31 and the right semi-circular ring 32, and the connector is rotatably connected to the throttle core.

[0049] In practical applications, the acceleration control structure 2 includes a Hall seat 21, a Hall seat cover 22, a magnet seat 23, a magnet 24, a Hall sensor 25, and a return spring 26. In this embodiment, the outer diameter of the magnet seat matches the inner diameter of the mounting cavity. The Hall seat and magnet seat can be plastic structures or structures made of materials such as aluminum. The magnet and Hall sensor are structures from existing technologies, and are simply applied; therefore, they are not described in detail.

[0050] For ease of installation and use, the bottom surface of the Hall seat is provided with a mounting cavity 4. Both the top wall of the mounting cavity and the bottom wall of the magnet seat have locking holes 5. The diameter of the locking holes matches the diameter of the locking posts of the return spring. The return spring has vertically bent locking posts 6 at both ends. During installation, the Hall seat cover plate is attached to the bottom surface of the Hall seat and fixed with several screws. The magnet seat is positioned within the mounting cavity and limited by the Hall seat cover plate. The return spring is positioned between the top wall of the mounting cavity and the top surface of the magnet seat, with the locking posts at both ends of the return spring respectively engaging in the locking holes for positioning. With this structure, the return spring is located within the mounting cavity of the Hall seat and engaged by the magnet seat, effectively preventing water from entering between the Hall seat and the magnet seat. This improves the waterproofness of the return spring, prevents corrosion, and extends its service life. When the magnet seat rotates relative to the Hall seat, it deforms and stores force, allowing the return spring to reset under the action of the return spring when no external force is applied.

[0051] The outer and inner sides of the magnet base are provided with magnet grooves 7, and the magnet grooves on the outer and inner sides are connected; the magnet is positioned and limited within the magnet grooves; the Hall sensor is mounted on the Hall base. During use, both the magnet and the magnet base are within the mounting cavity, which protects them from exposure and improves their stability and service life.

[0052] Meanwhile, in practical applications, two arc-shaped guide grooves 8 are provided in the middle of the top wall of the mounting cavity; a convex ring 9 is provided in the middle of the top surface of the magnet base, and two guide protrusions 28 are provided on the outer wall of the convex ring; the convex ring is located in the arc-shaped guide groove, and when the magnet base rotates, the convex ring moves within the arc-shaped guide groove and is limited by the end wall of the arc-shaped guide groove. The length of the guide protrusions is less than the length of the arc-shaped guide groove. The rotation angle of the magnet base is limited by the arc-shaped guide groove.

[0053] In practical applications, to improve the stability of the connection between the Hall sensor and the vehicle body, a locking protrusion 10 is provided on the top surface of the Hall sensor; a locking aluminum hoop 11 is provided on the outer side of the locking protrusion; during installation, the locking aluminum hoop is attached to the outer side of the locking protrusion and locked by a bolt 12 at the opening, with the bolt passing through the locking protrusion. Simultaneously, in practical applications, the Hall sensor is positioned between the left and right semi-circular rings, and the bolt passes through the side wall of the left semi-circular ring, fixing the Hall sensor and the locking aluminum hoop to the inner side of the left semi-circular ring. In this embodiment, the locking aluminum hoop is located inside the connector, which also helps improve waterproofing. The acceleration control structure 2 can be fixed inside the connector by the bolt, ensuring the stability and reliability of the connection.

[0054] In practical applications, the inner ring surface of the magnet base is provided with several vertical slots 13; and the outer wall of the end of the throttle core is provided with a vertical retaining bar 14; the vertical retaining bar of the throttle core is positioned and limited within the vertical slots; the throttle core rotates and can drive the magnet base to rotate relative to the Hall effect seat. Through the above structure, the throttle core and the magnet base can rotate synchronously, and the consistency and reliability of their rotation can also be guaranteed.

[0055] The outer wall of the throttle core is provided with an annular mounting groove 15, which is located below the vertical retaining strip; the bottom of the inner wall of the left and right semi-circular rings is provided with a semi-circular protrusion 16; during installation, the semi-circular protrusion can be rotatably engaged into the annular mounting groove. Through the above structure, not only can the connecting part and the throttle core be connected and used, but the throttle core can also rotate relative to the connecting part, meeting usage requirements.

[0056] The right semicircular ring is provided with a clearance slot 17, and a Hall sensor support 18 is integrally formed on the outer wall of the Hall seat; the Hall sensor is fixed inside the Hall sensor support, and the Hall sensor support passes through the clearance slot and extends out of the right semicircular ring. A Hall cover plate 19 is snapped onto the Hall sensor support. In this embodiment, the above structure can improve the convenience of Hall sensor installation and facilitate inspection and maintenance operations.

[0057] The bottom surface of the Hall seat is provided with an n-shaped limiting groove 20, and the top surface of the Hall seat cover plate is integrally formed with a number of limiting protrusions 27 that match the n-shaped limiting groove. The limiting protrusions are engaged in the n-shaped limiting groove, and the screws pass through the limiting protrusions and are threaded onto the top wall of the n-shaped limiting groove. In this embodiment, the above structure ensures the stability of the connection between the Hall seat and the Hall seat cover plate, preventing displacement or loosening, and is highly practical.

[0058] The invention has positive effects: The structure of the invention is reasonable. Its throttle core and acceleration control structure are connected by connectors. The acceleration control structure includes a Hall seat, a Hall seat cover, a magnet seat, a magnet, a Hall sensor, and a reset spring. It is composed of various components. Not only can the components be processed individually, thus enabling batch processing and improving processing efficiency, but when a component is damaged, only the corresponding component needs to be replaced, which helps to reduce the cost of disassembly and maintenance. It is also easy to disassemble and assemble, and has strong applicability and good practicality.

[0059] Meanwhile, the magnet base and the magnet are located in the mounting cavity of the Hall effect sensor, which helps to protect the magnet base and the magnet, thereby improving the service life and reliability of the magnet base and the magnet, making it highly practical.

[0060] Furthermore, a locking protrusion is provided on the top surface of the Hall seat; a locking aluminum hoop is provided on the outer side of the locking protrusion, which can ensure the stability and reliability of the installation position when the entire structure is connected to the vehicle body, preventing loosening or displacement, and making it highly practical.

[0061] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0062] Obviously, the above embodiments of the invention are merely examples for clearly illustrating the invention, and not intended to limit the implementation of the invention. Those skilled in the art will be able to make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of the invention still fall within the scope of protection of the invention.
