[0036] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] As mentioned in the background technology, most electric vehicles on the market currently use electronic speed control throttles based on three-wire voltage signals, which transmit speed control information through a circuit system consisting of power lines, ground lines, and signal lines.

[0039] However, the design has many technical problems in its implementation: on the one hand, the voltage signal is easily distorted by electromagnetic interference during transmission, and the signal attenuation caused by line impedance seriously affects the accuracy of vehicle speed control.

[0040] On the other hand, the three-wire (power, ground, signal) structure increases the complexity and cost of the vehicle wiring harness and makes it difficult to directly detect open or short circuit faults in the wiring.

[0041] Therefore, there is an urgent need to develop a two-wire electronic throttle throttle for vehicles based on current signals to improve the anti-interference capability of signal transmission, reduce signal attenuation, realize self-detection of circuit faults, and effectively reduce wiring harness costs and system complexity.

[0042] To address the aforementioned technical issues, this application provides an electronic speed control throttle, mounted on the handlebar. The throttle's rotor drives a permanent magnet to rotate, which, in conjunction with a Hall effect sensor integrated on the speed signal generation circuit board within the throttle bracket assembly, senses changes in the magnetic field to generate a speed control signal. Power is supplied to the Hall effect sensor and the speed signal generation circuit board via a power line, and the speed signal is then transmitted to the controller via a ground wire. Precise speed control is achieved through two wiring harnesses. Compared to the traditional three-wire design, this simplifies the wiring layout and reduces the overall wiring cost and complexity. Furthermore, the two-wire design allows the power line to perform both power supply and signal transmission functions. Based on the transmission characteristics of current signals, it is easier to detect faults such as continuity issues and short circuits, improving the system's fault diagnosis capabilities and more effectively meeting the vehicle's speed control requirements.

[0043] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with reference to optional embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] To better explain the electronic lock control circuit provided in the embodiments of this application, the vehicle equipped with the electronic lock control circuit will be described in detail below.

[0045] The vehicles provided in this application embodiment may include, but are not limited to, electric two-wheelers, electric tricycles, or electric four-wheelers. In this application embodiment, an electric two-wheeler is used as an example for illustrative purposes. Electric vehicles may include electric motorcycles and electric bicycles, etc., and the type of electric vehicle is not further limited.

[0046] Figure 1 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. See also... Figure 1 The vehicle 100 includes a controller 1, an electronic speed control throttle 2, and a handlebar 3.

[0047] Controller 1 can be understood as the core control unit of the entire vehicle 100, used to coordinate and control various systems of the vehicle. Depending on different vehicle models and design requirements, the location of controller 1 in the vehicle 100 may vary. For example, it may be installed in the front of the vehicle 100, under the pedals, or under the seat bucket, to adapt to the overall layout and functional requirements of the vehicle 100.

[0048] In some vehicles 100, to achieve better heat dissipation or for specific structural layouts, the controller 1 may be installed in other locations, such as the side or rear of the chassis. This application embodiment does not specifically limit the location of the controller 1 within the vehicle 100.

[0049] The electronic speed control throttle 2 is a key component for achieving precise speed adjustment. Its working principle is to convert the mechanical signal generated by the rotation of the throttle into an electrical signal and transmit it to the controller 1, thereby realizing the regulation of the motor speed.

[0050] It should be understood that the electronic speed control throttle 2 is typically mounted on the handlebar stem 3 of the vehicle 100 in a detachable or fixed manner. Optionally, the electronic speed control throttle 2 is positioned adjacent to the rider's hand grip area, facilitating the rider's control of the vehicle speed by rotating the throttle during riding. This ensures ease of operation and allows for efficient connection between the throttle and the vehicle's electrical system, ensuring stable transmission of the speed control signal.

[0051] Based on this, the electronic speed control throttle 2 and the controller 1 are connected by only two wires: a power wire and a ground wire. Compared with the traditional three-wire design, this simplifies the wiring and reduces the overall vehicle wiring harness cost and complexity. At the same time, the two-wire design also provides a foundation for enhancing subsequent fault detection capabilities, more effectively meeting the vehicle's speed control requirements.

[0052] The following description provides an example of the specific structures that each functional module in the electronic speed control throttle 2 may have, but it is not intended to limit this application.

[0053] Figure 2 This is a schematic diagram of an electronic speed control throttle provided as an embodiment of this application. See also... Figure 2 The electronic speed control throttle 2 includes a throttle operation component 21, a throttle support component 22, and a connecting wire 23. The throttle operation component 21 includes a handlebar rotor 211 rotatable around the central axis of the handlebar tube 3, and a permanent magnet 212 disposed on the handlebar rotor 211. The throttle support component 22 includes a support structure 221 and a speed control signal generation circuit board 222 fixed within the support structure 221. The speed control signal generation circuit board 222 integrates a Hall element 22211, which is within the sensing range of the permanent magnet 212 and is used to sense the magnetic field change caused by the rotation of the permanent magnet 212, generating a corresponding speed control signal. The connecting wire includes a power line and a ground line. The first end of the power line is connected to the controller 1, and the second end VDD2 of the power line is connected to the speed control signal generation circuit board 222. The ground line 232 is connected to both the speed control signal generation circuit board 222 and the controller 1.

[0054] In this application, the electronic speed control throttle 2 mainly consists of three parts: a throttle bracket assembly 22, a throttle operation assembly 21, and a connecting wire 23. The throttle is mounted on the vehicle handlebar 3 and is electrically connected to the controller 1 via a two-wire connecting wire 23 containing only a power line and a ground line. Specifically, the power line provides power for signal generation, and the ground line transmits the signal. Compared to the traditional three-wire design, this two-wire wiring architecture ensures the vehicle's precise speed control requirements while simplifying the overall vehicle wiring layout, reducing wiring harness costs and wiring complexity, and effectively improving the integration and reliability of the vehicle's electrical system.

[0055] Optionally, the handlebar rotor 211 included in the throttle operation assembly 21 may be made of high-strength engineering plastics, such as polycarbonate, which has good wear resistance and impact resistance, so as to withstand the friction and external impact caused by the rider's frequent turning operation.

[0056] The handle rotor 211 can be designed as a hollow cylinder with its inner diameter matching the outer diameter of the handle tube 3. The two are fitted with a clearance to ensure that the handle rotor 211 can rotate flexibly around the central axis of the handle tube 3.

[0057] In some cases, anti-slip textures can be designed on the outer surface of the leather rotor 211 to make it easier for riders to grip and rotate.

[0058] Optionally, the permanent magnet 212 can be glued to the handlebar rotor 211 to ensure that the permanent magnet 212 can rotate synchronously with the handlebar rotor 211.

[0059] In practical applications, to ensure the reliability of signal generation by the electronic speed control throttle, the permanent magnet 212 can be equipped with a magnetic component that can generate a strong and stable magnetic field, thereby providing reliable conditions for the Hall element to accurately sense changes in the magnetic field and ensuring the accuracy and stability of the speed control signal generation.

[0060] Optionally, the permanent magnet can be made of magnetic steel. Depending on the application scenario and structural design requirements, the types of magnetic steel include, but are not limited to, tile-shaped magnetic steel, toroidal magnetic steel, and rectangular magnetic steel. Among them, tile-shaped magnetic steel can optimize the magnetic field distribution through special curvature design; toroidal magnetic steel can form a uniform circumferential magnetic field and is suitable for rotating structures; rectangular magnetic steel is convenient for modular installation and layout. All three types can effectively meet the magnetic field strength and direction requirements in different scenarios.

[0061] See also Figure 2 Based on the above implementation, a groove 2111 is provided at one end of the leather rotor 211, and the permanent magnet 212 is installed in the groove 2111. The distance between the speed regulation signal generation circuit board 222 and the groove 2111 is smaller than the sensing range of the Hall element 22211.

[0062] Optionally, a groove 2111 is provided on one end of the handle rotor 211 near the handle tube 3, the shape of the permanent magnet 212 matches the shape of the groove 2111, and the permanent magnet 212 can also be fixed in the groove 2111.

[0063] Based on this, the distance between the groove 2111 and the speed control signal generation circuit board 222 can be controlled to be less than the sensing range of the Hall element 22211, ensuring that the Hall element 22211 is within the effective range of the magnetic field change of the permanent magnet 212. In this way, when the rider turns the handlebar rotor 211, causing the permanent magnet 212 to rotate, even the slightest change in the magnetic field can be quickly and accurately sensed by the Hall element 22211, ensuring the sensitivity and reliability of the speed control system.

[0064] Based on the above embodiments, the throttle support assembly 22 mainly includes a support structure 221 and a speed control signal generation circuit board 222. The support structure 221 provides a stable installation environment for the speed control signal generation circuit board 222, preventing the circuit board from being interfered with or damaged by external factors, thus playing a supporting and protective role.

[0065] The speed control signal generation circuit board 222 integrates a Hall element 22211, which is positioned within the sensing range of the permanent magnet 212. When the permanent magnet 212 rotates with the throttle operation, the magnetic field around it changes accordingly. The Hall element 22211 senses these magnetic field changes and converts them into corresponding electrical signals. After processing by the circuit board, a speed control signal with practical control significance is generated. This signal is transmitted to the controller 1, thereby achieving precise adjustment of the vehicle speed.

[0066] In this application, the speed control signal generation circuit board 222 is electrically connected to the controller 1 via a two-wire connection line 23 containing only a power line and a ground line. The power line provides a stable power supply to the speed control signal generation circuit board 222, ensuring its normal operation. The speed control signal is transmitted to the controller 1 via the ground line. The controller 1 adjusts the output power of the motor in the vehicle based on the received speed control signal, thereby controlling the vehicle's speed. Optionally, in some cases, the ground line can also provide a stable reference potential for the circuitry in the speed control signal generation circuit board 222, reducing the impact of external electromagnetic interference on signal transmission and ensuring accurate transmission of the speed control signal.

[0067] The electronic speed control throttle and vehicle provided in this application have an electronic speed control throttle mounted on the handlebar. The throttle operating assembly 21 uses a handlebar rotor to drive a permanent magnet to rotate. This, in conjunction with a Hall effect sensor integrated on the speed signal generation circuit board in the throttle bracket assembly 22, senses changes in the magnetic field to generate a speed control signal. Power is supplied to the Hall effect sensor and the speed signal generation circuit board via a power line, and the speed control signal is then transmitted to the controller via a ground wire. Precise speed control of the vehicle is achieved through two wiring harnesses. Compared to the traditional three-wire design, this simplifies the wiring layout and reduces the overall wiring cost and complexity. Furthermore, the two-wire design allows the power line to perform both power supply and signal transmission functions. Based on the transmission characteristics of current signals, it is easier to detect faults such as continuity issues and short circuits, improving the system's fault diagnosis capabilities and more effectively meeting the vehicle's speed control requirements.

[0068] The following description provides an example of the specific structures that each functional module in the speed control signal generation circuit board 222 may have, but it is not intended to limit this application.

[0069] Figure 3 This is a schematic diagram of a speed control signal generation circuit board provided in an embodiment of this application. See also... Figure 3 Based on the above embodiments, the speed control signal generation circuit board 222 further includes a Hall module 2221 and a signal generation module 2222; the Hall module 2221 includes a Hall element 22211; the power supply terminal of the signal generation module 2222 and the power supply terminal of the Hall module 2221 are respectively connected to the power supply terminal of the controller 1 through power lines; the output terminal of the Hall module 2221 is connected to the input terminal of the signal generation module 2222; the ground terminal of the signal generation module 2222 is connected to the input terminal of the controller 1 through a ground wire.

[0070] Optionally, the speed control signal generation circuit board 222 is further divided into a Hall module 2221 and a signal generation module 2222. The Hall module 2221 contains a Hall element 22211, used to sense changes in the magnetic field caused by the rotation of the permanent magnet 212. The power supply terminals of both the signal generation module 2222 and the Hall module 2221 are connected to the power supply terminal of the controller 1 via power lines to obtain electrical energy to maintain normal module operation. The output terminal of the Hall module 2221 is connected to the input terminal of the signal generation module 2222, transmitting the signal generated by the changes in the magnetic field sensed by the Hall element 22211 to the signal generation module 222 for processing. Optionally, the ground terminal of the signal generation module 2222 is connected to the input terminal of the controller 1 via a ground wire, providing a stable reference potential for signal transmission and ensuring that the speed control signal can be reliably transmitted from the speed control signal generation circuit board 222 to the controller 1, thereby achieving precise control of vehicle speed.

[0071] Figure 4This is a schematic diagram of another speed control signal generation circuit board provided in an embodiment of this application. See also... Figure 4 Based on the above implementation, the signal generation module 2222 further includes a current compensation module 22221 and a current generation module 22222; the current compensation module 22221, the current generation module 22222, and the Hall module 2221 are respectively connected to the power supply terminal of the controller 1 via power lines; the ground terminal of the current compensation module 22221 is connected to the input terminal of the current generation module 22222, and the output terminal of the current compensation module 22221 is connected to the input terminal of the current generation module 22222; the ground terminals of the current compensation module 22221 and the current generation module 22222 are respectively connected to the input terminal of the controller 1 via ground wires.

[0072] Optionally, the signal generation module 2222 further includes a current compensation module 22221 and a current generation module 22222. The current compensation module 22221, the current generation module 22222, and the Hall module 2221 are all connected to the power supply terminal of the controller 1 via a power line to obtain the electrical energy required to generate the signal. Furthermore, the ground terminal and output terminal of the current compensation module 22221 are both connected to the input terminal of the current generation module 22222, allowing the current compensation module 22221 to compensate and adjust the current before supplying it to the current generation module 22222. Simultaneously, the ground terminals of the current compensation module 22221 and the current generation module 22222 are respectively connected to the input terminal of the controller 1 via ground wires. This provides a stable reference potential for the modules and transmits the processed current signal to the controller 1, ensuring the accuracy and stability of the speed control signal generation and transmission, and achieving precise control of the vehicle speed.

[0073] See also Figure 2 The connection cable 23 provided in this application includes a two-core cable plug-in 231. The first end of the two-core cable plug-in 231 is connected to the speed regulation signal generation circuit board 222, and the second end of the two-core cable plug-in 231 is connected to the controller 1.

[0074] In this application, a two-core wire plug-in 231 is used to replace the connection harness between the speed control signal generation circuit board 222 and the controller 1. This can standardize and facilitate the electrical connection between the electronic speed control throttle 2 and the controller 1, making it easier for the vehicle to be assembled, debugged and maintained, and improving the reliability and practicality of the speed control system.

[0075] Optionally, the first end of the two-core plug-in 231 is closely connected to the speed control signal generation circuit board 222, and is responsible for receiving the speed control signal generated by the circuit board, as well as the power supply provided by the power line and the reference potential of the ground line; its second end is stably connected to the controller 1, accurately transmitting the received speed control signal to the controller 1, while ensuring the stability of power supply and potential reference.

[0076] See also Figure 2 Based on the above embodiments, the throttle bracket assembly 22 further includes a Hall cover plate 223 and a first fixing member 224, and the bracket structure 221 is provided with a cavity; the speed regulation signal generation circuit board 222 is fixed inside the cavity, the Hall cover plate 223 covers the outside of the cavity, and the first fixing member 224 is used to achieve a tight connection between the Hall cover plate 223 and the bracket structure 221, so as to encapsulate the speed regulation signal generation circuit board 222 inside the cavity.

[0077] Optionally, the throttle bracket assembly 22 also includes a Hall cover plate 223 and a first fixing member 224, which work in conjunction with the cavity of the bracket structure 221 to protect the speed control signal generation circuit board 222 placed in the throttle bracket assembly 22.

[0078] Optionally, the bracket structure 221 has a closed cavity inside for mounting the speed control signal generation circuit board 222. The cavity can be designed to just accommodate the circuit board to save space. In some cases, shock-absorbing rubber pads can also be installed on the inner wall of the cavity to reduce the impact of external vibrations on the circuit board. After the speed control signal generation circuit board 222 is fixed inside the cavity, the Hall cover plate 223, as an outer protective component, covers the opening of the cavity, completely enclosing the circuit board and providing protection.

[0079] Optionally, the first fixing component 224 (such as screws, clips, or other fastening parts) plays a connecting role in the structure. By firmly connecting the Hall cover plate 223 to the bracket structure 221, it not only effectively prevents external impurities such as dust and moisture from entering the cavity 2211 and interfering with the operation of the circuit board, but also resists vibration and external impact during vehicle operation, preventing the circuit board from loosening, shifting, or being damaged. In this way, the sensing accuracy of the Hall element 22211 to changes in the magnetic field is guaranteed, and the working stability and service life of the speed control signal generation circuit board 222 are improved, thereby ensuring that the electronic speed control throttle 2 can continuously and reliably output speed control signals.

[0080] See also Figure 2 Based on the above embodiments, the electronic speed control throttle also includes a torsion spring 24; the first end of the torsion spring 24 is connected to the throttle operation component 21, and the second end of the torsion spring 24 is connected to the throttle bracket component 22.

[0081] In this application, the torsion spring 24 serves as an elastic component in the overall structure of the electronic speed control throttle, connecting the throttle operating assembly 21 and the throttle support assembly 22. Optionally, when the rider rotates the throttle operating assembly 21 (such as the handlebar rotor 211), the assembly causes the first end of the torsion spring 24 to displace, forcing the torsion spring to undergo elastic deformation and store elastic potential energy; while the second end of the torsion spring 24 is firmly connected to the throttle support assembly 22, providing a fixed fulcrum for the deformation of the torsion spring. When the rider stops applying external force, the torsion spring 24 drives the throttle operating assembly 21 to automatically reset by relying on its elastic restoring force, returning it to its initial position, ensuring that the speed control throttle can stably return to zero after each operation, providing a consistent starting state for the next speed adjustment operation. In this way, the accuracy and stability of the speed adjustment signal can be guaranteed through the automatic reset mechanism, effectively avoiding the problem of inaccurate vehicle speed control caused by throttle position deviation.

[0082] See also Figure 2 Based on the above embodiments, the throttle bracket assembly 22 further includes a second fixing member 225; the second fixing member 225 is connected to the throttle bracket assembly 22 and the handlebar 3 respectively.

[0083] Optionally, the second fixing member 225 can be disposed between the Hall cover plate 223 and the bracket structure 221 to achieve a stable assembly between the throttle bracket assembly 22 and the handlebar tube 3. Specifically, one end of the second fixing member 225 is tightly connected to the throttle bracket assembly 22, and the bracket structure 221 can be stably fixed by mechanical connection methods such as snap-fit, bolt fastening, and nested positioning; the other end is reliably connected to the handlebar tube 3, for example by using clamping and locking, threaded connection through fixing, and slot matching to ensure that the position of the electronic speed control throttle 2 relative to the handlebar tube 3 is fixed.

[0084] In this way, the connection of the second fastener 225 not only enables the throttle bracket assembly 22 to provide a stable support environment for the internal speed control signal generation circuit board 222, ensuring the normal operation of precision components such as the Hall element 22211, but also allows the entire electronic speed control throttle 2 to maintain a precise position during the rider's operation, avoiding the impact of loosening or displacement on magnetic field induction and signal transmission, thereby achieving reliable adjustment of vehicle speed.
