Description

Technical Field

[0001] The present invention belongs to the technical field of scooters, and particularly relates to a 360-degree steering device and control method for an electric scooter based on light-sensing transmission. Background Art

[0002] In the field of children's toys, scooters, as a popular category of children's toys, bring rich fun to children while exercising their balance and control abilities with their unique driving experience. However, there are many problems to be solved urgently in the drive control and power supply of existing scooters, which seriously affect the safety, reliability and use experience of the products. Especially in the key function of controlling the on-off of the motor by rotating the steering wheel, the existing technology has significant deficiencies.

[0003] Disadvantages of Traditional Drive Control Methods Poor reliability of contact connection: Currently, most scooters adopt foot pedal contact type drive control instead of controlling the on-off of the motor by rotating the steering wheel. During children's frequent play, the foot pedal switch contacts and separates from the conductive copper sheet frequently. Coupled with the vibration during vehicle driving, it is very easy for the two to have problems such as virtual connection, jamming or copper sheet deformation. Once a virtual connection occurs, the motor control signal will be interrupted, resulting in a sudden loss of vehicle power; while jamming or copper sheet deformation may cause abnormal conduction of the signal, resulting in the vehicle suddenly accelerating or running out of control. For example, when a child quickly steps on the foot pedal switch, due to vibration and too fast operation frequency, the conductive copper sheet is prone to displacement and deformation, resulting in abnormal vehicle driving. This unstable drive control greatly increases the safety risk during children's play and may cause children to fall and get injured. At the same time, since it is not based on rotating the steering wheel to control the motor, children cannot intuitively control the vehicle power immediately by manipulating the steering wheel, reducing the continuity and fun of operation.

[0004] Poor environmental adaptability: The protection measures of traditional contact type drive structures are extremely limited. Usually, only simple encapsulation is carried out, making it difficult to resist the erosion of environmental factors such as dust and water vapor. In actual use scenarios, scooters are often used in various indoor and outdoor environments. Dust is easy to accumulate on the surface of the contacts, hindering the normal conduction of current. When encountering a humid environment, such as playing on a wet ground or accidentally splashing water, moisture seeps into the contacts, causing problems such as damp short-circuiting and oxidation rusting, which may further lead to a short circuit in the circuit. The short circuit will not only damage the electrical system of the vehicle, but also pose an electric shock risk to children when the vehicle is running, seriously threatening the personal safety of children. In addition, the stability of this traditional drive method in different environments is poor, making it difficult to apply the technology of controlling the on-off of the motor by rotating the steering wheel, restricting the improvement of the control performance of scooters.

[0005] Deficiencies of Existing Power Supply Technologies Poor power supply stability: Most existing power supply systems for twist cars rely on traditional battery connection methods and simple circuit designs. During vehicle operation, especially when passing over bumpy roads or being collided with, the battery connections are prone to loosen, resulting in unstable power supply. This not only affects the normal operation of the motor, causing the vehicle to have inconsistent power during driving, but may also damage the battery and shorten its service life. The unstable power supply makes it more difficult to precisely control the motor on and off through the rotation of the steering wheel. Because under unstable power supply, the motor cannot respond stably and accurately to the control signals generated by the rotation of the steering wheel, further reducing the driving experience and safety.

[0006] Complex structure and low space utilization: The power supply and control structures of traditional twist cars often separately control the steering wheel rotation and motor drive. This design makes the vehicle's internal structure complex with numerous components. The complex structure not only increases the production cost but also occupies a large amount of interior space, making the vehicle layout less compact and reasonable. For children's toys, a complex structure means a higher risk of failure. Once a component fails, it is difficult to repair, and the repair cost may be too high, leading to premature scrapping of the toy. At the same time, the complex structure is not conducive to children's operation and understanding of the vehicle, reducing the fun of playing. Moreover, the separated structure is not conducive to directly controlling the motor on and off through the rotation of the steering wheel, increasing the difficulty and cost of technical implementation.

[0007] Limitations of existing improvement measures To address the above problems, some manufacturers have taken a series of improvement measures. For example, increasing the thickness and strength of the conductive copper sheets in an attempt to reduce the probability of copper sheet deformation; improving the sealing design of the outer shell to reduce the intrusion of dust and moisture; optimizing the battery connection structure to improve power supply stability. However, these improvement measures only perform partial optimizations based on traditional technologies and fail to fundamentally solve the problems. Increasing the thickness and strength of the copper sheets reduces copper sheet deformation to a certain extent but cannot avoid problems such as loose contact and jamming; improving the outer shell sealing can only delay the intrusion of dust and moisture and cannot completely prevent it; optimizing the battery connection structure is also difficult to cope with the impacts caused by severe vibrations and collisions. In addition, the separated control structure still exists, and the problems of complex overall vehicle structure and low space utilization have not been substantially improved. These limitations make it difficult to effectively apply the innovative technology of controlling the motor on and off through the rotation of the steering wheel in existing twist car products, unable to meet the needs of the children's toy market for twist car products that are safe, stable, easy to use, and provide a good operating experience.

[0008] In summary, there are many deficiencies in the existing scooters in terms of drive control and power supply, which seriously restrict the product quality and safety. Especially, there is a technical bottleneck in realizing the function of controlling the motor on and off through the rotation of the steering wheel. Therefore, it is urgent to develop a new and reliable drive control and power supply technology for scooters to meet the needs of the children's toy market for safe, stable and easy-to-use scooter products, and at the same time improve the operation experience and fun of children driving scooters. Summary of the Invention

[0009] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a 360-degree steering device and control method for an electric scooter based on optical transmission, aiming to solve the problems of the existing scooters in drive control and power supply. It focuses on realizing the control of the motor on and off through the rotation of the steering wheel, and by cooperating with the steering wheel rotation sensor and the main control circuit board, it improves the driving control feeling and fun; uses designs such as bearings and conductive steering tubes and insulating sleeves to enhance the stability and reliability of power supply and control, and reduce safety risks; optimizes the vehicle structure, simplifies the internal layout, improves the space utilization rate and product quality; enhances the environmental adaptability and reduces the influence of external factors on the circuit; at the same time promotes the technological innovation and development of scooters to meet the market demand for high-quality products.

[0010] To achieve the above object, in the first aspect of the present invention, a 360-degree steering device for an electric scooter based on optical transmission is provided, including a first bearing, a second bearing, a third bearing, an insulating sleeve, a hollow steering tube, a housing, a main control circuit board and a steering wheel rotation sensor; wherein The first bearing is arranged in the lower region of the steering tube, and the third bearing is arranged in the upper region of the steering tube; the second bearing is sleeved on the steering tube, and electrical isolation is achieved between the first bearing and the second bearing through the insulating sleeve; The housing is sleeved on the outer ring of the third bearing, and the housing body has a receiving cavity, and light blocking sheets are arranged at intervals in a circle in the receiving cavity; The steering wheel rotation sensor is used to monitor the rotation action of the steering wheel. The steering wheel rotation sensor rotates synchronously with the steering wheel. During the rotation process, the light blocking sheet will alternately block and leave the optical path of the steering wheel rotation sensor to form a rotation signal, and transmit the corresponding rotation signal to the main control circuit board; A on-off switch is arranged in the main control circuit board, and the main control circuit board controls the on-off switch to conduct or disconnect according to the received rotation signal to achieve the on-off control of the motor.

[0011] Further, it further includes a power supply module for storing and providing electric energy to the motor and the main control circuit board; Further, the main control circuit board is disposed near one end of the steering tube, and the motor is disposed at the other end of the steering tube. The motor is mounted on the front fork that rotates synchronously with the steering tube, so that the steering tube, the front fork, and the motor form an integrally rotatable unit.

[0012] Further, it further includes a first positive wire, a second positive wire, a first positive conductive sheet, and a second positive conductive sheet; The first positive conductive sheet is electrically connected to the outer ring of the second bearing; the second positive conductive sheet is electrically connected to the inner ring of the second bearing; One end of the first positive wire is connected to the positive pole of the power supply module; the other end of the first positive wire is electrically connected to the first positive conductive sheet; one end of the second positive wire is electrically connected to the second positive conductive sheet, and the other end of the second positive wire is connected to the positive pole of the motor.

[0013] Further, it further includes a first negative wire, a steering tube, and a second negative wire; One end of the first negative wire is connected to the negative pole of the power supply module; the other end of the first negative wire is electrically connected to the outer ring of the first bearing, and the inner ring of the first bearing is electrically connected to the steering tube, using the steering tube as a power supply conductor; one end of the second negative wire is electrically connected to one end position of the steering tube, and the other end of the second negative wire is connected to the negative input terminal of the main control circuit board.

[0014] Further, it further includes a third positive wire. One end of the third positive wire is electrically connected to the second positive wire, and the other end of the third positive wire extends upward from the bottom of the steering tube along the internal hollow area and then extends out of the steering tube and is connected to the positive input terminal of the main control circuit board.

[0015] Further, it further includes a signal wire. The signal wire is a power supply wire for controlling the on / off operation of the motor; one end of the signal wire is electrically connected to the on / off switch in the main control circuit board, and the other end of the signal wire is connected to the negative pole of the motor.

[0016] In a second aspect of the present invention, there is provided a control method for a 360-degree steering device of an electric scooter based on light-sensing transmission, which uses the above-mentioned power supply device for the scooter; it is applied to an electric scooter steering device including a steering wheel rotation sensor, a main control circuit board, a motor, and a power supply module. The control method includes: Obtain the light-sensing change signal generated by the rotation of the steering wheel through the steering wheel rotation sensor, and convert the rotation action of the steering wheel into a rotation signal in the form of an electrical signal; Transmit the rotation signal to the main control circuit board. The main control circuit board processes and analyzes the signal, and makes a decision on the on / off control of the motor according to the processing result; According to the decision of the main control circuit board, control the power-on or power-off state of the motor to achieve the control of the power of the scooter; Further, the light-sensing change signal generated by the rotation of the steering wheel is obtained through the steering wheel rotation sensor, and the rotation action of the steering wheel is converted into a rotation signal in the form of an electrical signal.

[0017] An on-off switch is set in the main control circuit board. The rotation signal is transmitted to the main control circuit board. The main control circuit board processes and analyzes the signal, and makes a motor on-off control decision based on the processing result. Specifically, the steering wheel rotation sensor transmits the rotation signal to the main control circuit board. After the main control circuit board filters and amplifies the signal, it judges whether to start or stop the motor, and then controls the on or off of the on-off switch.

[0018] Further, in the motor control step, when the on-off switch is turned on, the power supply module supplies power to the positive pole of the motor through the first positive wire, the first positive conductive piece, the outer and inner rings of the second bearing, the second positive conductive piece and the second positive wire. At the same time, the negative pole of the power supply module passes through the first negative wire, the outer and inner rings of the first bearing, the steering tube and the second negative wire to participate in forming the motor power supply circuit, so that the motor runs; when the on-off switch is turned off, the motor stops being powered.

[0019] Further, the power supply module supplies power to the motor and the main control circuit board respectively. The positive pole of the power supply module also supplies power to the positive input terminal of the main control circuit board through the third positive wire. The negative pole of the power supply module is connected to the negative input terminal of the main control circuit board through the second negative wire. And electrical isolation is achieved between the first bearing and the second bearing through an insulating sleeve to ensure electrical safety during the power supply process.

[0020] Further, when the steering wheel rotates, it drives the steering tube to rotate. The steering tube drives the motor to rotate synchronously through the front fork that rotates synchronously with it, realizing 360-degree steering. And the second bearing rotates synchronously with the steering tube, driving the second positive wire connected to it to rotate synchronously, avoiding wire entanglement.

[0021] The 360-degree steering device of the electric scooter based on light-sensing transmission of the present invention has the following beneficial effects: The control experience is significantly improved: With the cooperation of the steering wheel rotation sensor and the main control circuit board, the on-off of the motor is controlled by rotating the steering wheel. Children can intuitively control the start and stop of the vehicle by turning the steering wheel, enhancing the coherence and fun of driving, greatly improving the operation experience, and giving children a greater sense of control during play.

[0022] The stability and reliability are enhanced Stable drive control: Abandoning the traditional foot-contact drive control, it avoids the problems of virtual connection, jamming, and deformation between the foot switch and the conductive copper sheet, ensures the stable transmission of motor control signals, reduces the situation of sudden loss of vehicle power or abnormal acceleration, and lowers the safety risk when children are playing.

[0023] Stable and reliable power supply: Adopting the design of conducting electricity through the first bearing, the second bearing, and the steering tube, and cooperating with the insulating sleeve to achieve electrical isolation, it optimizes the power supply circuit and reduces the problem of unstable power supply caused by vibration, bump, etc. Even when driving on complex road conditions, it can ensure the stable power supply of the motor and the main control circuit board, and extends the battery service life.

[0024] Rationally optimized structure Compact layout: Integrating the steering wheel steering and the motor drive, it simplifies the internal structure of the vehicle, reduces the number of components, improves the utilization rate of the interior space of the vehicle, and makes the overall layout of the vehicle more compact and reasonable.

[0025] Reducing costs and failure risks: The simplification of the structure not only reduces the production cost, but also reduces the probability of failures. When problems occur, the maintenance difficulty and cost are also correspondingly reduced, avoiding premature scrapping of the toy.

[0026] Improved environmental adaptability: The protection of the traditional contact drive structure is limited, while this device effectively isolates the key conductive components from the external environment, reducing the erosion effect of dust, water vapor, etc. on the circuit. When the vehicle is used in different environments, it can better resist external factor interference, ensure stable operation, and extend the service life of the product.

[0027] Promoting technological innovation: This invention combines the rotation control of the steering wheel to turn on and off the motor with the innovative power supply and conduction technology, providing a new technical idea and solution for the twister scooter industry. It promotes the innovative development of twister scooter technology in terms of intelligence, safety, and reliability, leads the technological upgrade of the industry, and meets the market demand for high-quality twister scooter products.

[0034] As an implementation, in this embodiment, a first positive wire 9, a second positive wire 10, a first positive conductive sheet 12, and a second positive conductive sheet 13 are further included; The first positive conductive sheet 12 is electrically connected to the outer ring of the second bearing 6; the second positive conductive sheet 13 is electrically connected to the inner ring of the second bearing 6; One end of the first positive wire 9 is connected to the positive pole of the power supply module 4; the other end of the first positive wire 9 is electrically connected to the first positive conductive sheet 12; one end of the second positive wire 10 is electrically connected to the second positive conductive sheet 13, and the other end of the second positive wire 10 is connected to the positive pole of the motor 1.

[0037] As an implementation, in this embodiment, a signal wire 16 is further included. The signal wire 16 is a power supply wire and is used to control the on / off operation of the motor 1; one end of the signal wire 16 is electrically connected to the on / off switch in the main control circuit board 3, and the other end of the signal wire 16 is electrically connected to the negative pole of the motor 1.

[0038] The following is an explanation of the working principle of the 360-degree steering device of the electric scooter based on light-sensing transmission: Power supply principle Positive power supply circuit: The power supply module 4 stores electrical energy. Its positive electrode is connected to the first positive electrode conductor 9, and the first positive electrode conductor 12 is electrically connected to the outer ring of the second bearing 6. The inner ring of the second bearing 6 is electrically connected to the second positive electrode conductor 13, and the second positive electrode conductor 13 is connected to the positive electrode of the motor 1 through the second positive electrode wire 10 to provide a positive voltage for the motor 1. At the same time, one end of the third positive electrode wire 11 is electrically connected to the second positive electrode wire 10, and the other end extends upward from the bottom of the steering tube 8 along its internal hollow area and then is connected to the positive electrode input terminal of the main control circuit board 3 to provide a positive voltage for the main control circuit board 3.

[0039] Negative power supply circuit: In terms of negative power supply, the negative electrode of the power supply module 4 is connected to one end of the first negative electrode wire 14. In this embodiment, a negative electrode conductive sheet 22 is further included. The negative electrode conductive sheet 22 is electrically connected to the first bearing. The other end of the first negative electrode wire 14 is connected to the negative electrode conductive sheet 22. The negative electrode conductive sheet 22 is electrically connected to the outer ring of the first bearing 5. The bearing itself is conductive. The inner ring of the first bearing 5 is electrically connected to the steering tube 8. The steering tube 8 serves as a power supply conductor to conduct the current to the position connected to the second negative electrode wire 15. One end of the second negative electrode wire 15 is connected to the steering tube 8, and the other end is connected to the negative electrode input terminal of the main control circuit board 3 to complete the negative circuit.

[0040] Here, it needs to be supplemented that in this embodiment, the bearing itself is a conductor. The bearing includes an outer ring, an inner ring, and rotating steel balls located between the outer ring and the inner ring. The bearing itself is an existing technology. When there is electricity on the outer ring of the bearing, there is also electricity on the inner ring of the bearing.

[0041] The positive electrode conductive sheet / negative electrode conductive sheet in this embodiment is used for wiring. The wire is connected to this conductive sheet, and the conductive sheet is electrically connected to the outer ring of the bearing. Since the outer ring of the bearing does not rotate, the conductive sheet can be electrically connected to the outer ring of the bearing by using screws to fix or welding to fix, etc.

[0042] It should be emphasized in this embodiment that electrical isolation between the first bearing 5 and the second bearing 6 is achieved through the insulating sleeve 7; that is, there is no electrical conduction between the first bearing and the second bearing; the implementation method is: the first bearing 5 is sleeved on the steering tube 8. At the same time, the insulating sleeve is also sleeved on the rotating tube 8, and then the second bearing is sleeved on the insulating sleeve 7 to achieve electrical isolation in this way.

[0043] As Figure 5 shown, the insulating sleeve 7 has a cylindrical sleeve. The inner surface of the sleeve is sleeved on the steering tube 8, and the outer side surface of the sleeve is sleeved with the second bearing 6, so as to achieve electrical isolation between the steering tube 8 and the second bearing 6. At the same time, the insulating sleeve 7 also has a protruding edge extending outward, and this protruding edge achieves electrical isolation between the side of the first bearing 5 and the side of the second bearing 6.

[0044] Steering Signal Monitoring and Motor 1 Control Principle Steering signal generation: The steering wheel rotation sensor 2 rotates synchronously with the steering wheel 18. When the steering wheel 18 rotates, the light-shielding plates 17 arranged at intervals in a circle around the inner cavity 21 of the housing 19 will alternately block and leave the optical path of the steering wheel rotation sensor 2. This change in the optical path forms a rotation signal, which reflects the rotation action information of the steering wheel 18.

[0045] As Figure 4 shown, inside the inner cavity 21, the light-shielding plates 17 are arranged at intervals in a circle, and several light-shielding plates 17 are arranged at equal intervals in a circle. The light-shielding plates 17 are fixed. The steering wheel rotation sensor 2 rotates synchronously with the steering wheel 18. When the steering wheel 18 rotates, it synchronously drives the steering wheel rotation sensor 2 to rotate. In this embodiment, an optoelectronic sensor is used. The optoelectronic sensor itself has a recessed notch; when the steering wheel drives the optoelectronic sensor to rotate, the optoelectronic sensor rotates in the circumferential direction, and the light-shielding plates 17 will alternately block and leave the notch position of the optoelectronic sensor, that is, the light-shielding plates 17 will alternately block and leave the optical path of the steering wheel rotation sensor 2. In this way, a rotation signal is formed.

[0046] Signal transmission and processing: The steering wheel rotation sensor 2 transmits the generated rotation signal to the main control circuit board 3. After receiving the signal, the main control circuit board 3 analyzes and processes it.

[0047] On-off control of the motor 1: An on-off switch is provided in the main control circuit board 3. According to the received rotation signal, the main control circuit board 3 controls the on-off switch to conduct or disconnect. When the on-off switch conducts, the power supply module supplies power to the positive electrode of the motor 1 through the power supply line, and at the same time, the signal line 16 is connected to provide a loop for the negative electrode of the motor 1, and the motor 1 is powered on and runs, and the scooter starts or continues to run; when the on-off switch disconnects, the motor 1 stops being powered, and the scooter stops running, thus realizing the on-off control of the motor 1 by rotating the steering wheel 18.

[0048] The on-off switch in this embodiment can use an on-off relay as the on-off switch. The main control circuit board 3 controls the on-off relay to conduct or disconnect according to the received rotation signal. When the on-off relay is connected, the signal line 16 is powered on and the motor is powered on and runs; when the on-off relay is disconnected, the signal line 16 loses power and the motor stops being powered.

[0049] Overall rotation principle The main control circuit board 3 is arranged at one end close to the steering tube 8. The motor 1 is mounted on the other end of the steering tube 8 through a front fork that rotates synchronously with the steering tube 8, so that the steering tube 8, the front fork and the motor 1 form an integrally rotatable whole. During the steering process of the scooter, the steering wheel 18 drives the steering tube 8 to rotate, and then drives the front fork and the motor 1 to rotate synchronously, realizing the 360-degree steering function.

[0050] In this embodiment, the steering tube 8, the front fork, the motor 1 and the second bearing 6 form an integrally rotatable integrated system. The second bearing 6 is sleeved on the steering tube 8, and during the rotation of the steering tube 8, the second bearing 6 rotates synchronously with it. Since the second positive conductive sheet 13 is electrically connected to the inner ring of the second bearing 6, and one end of the second positive wire 10 is connected to the second positive conductive sheet 13 and the other end is connected to the positive pole of the motor 1, the second positive wire 10 participates in the synchronous rotation as a part of this integrated system. With such a design, the problem of wire entanglement caused by asynchronous rotation of components is avoided, ensuring the stability and reliability of the power supply line during the 360-degree steering process of the device, ensuring the smooth transmission of electric energy, and thus maintaining the normal operation of the motor 1 and the entire system.

[0051] In this embodiment, the positive wire, the negative wire, and the signal wire are all wires wrapped with an insulating outer skin.

[0052] This embodiment provides a control method for a 360-degree steerable device of an electric scooter based on light-sensing transmission, using the above-mentioned power supply device for the scooter; applied to an electric scooter steering device including a steering wheel rotation sensor, a main control circuit board, a motor, and a power supply module, the control method includes: Obtain the light-sensing change signal generated by the rotation of the steering wheel through the steering wheel rotation sensor, and convert the rotation action of the steering wheel into a rotation signal in the form of an electrical signal; Transmit the rotation signal to the main control circuit board, and the main control circuit board processes and analyzes the signal, and makes a control decision on the on / off of the motor according to the processing result; According to the decision of the main control circuit board, control the on or off state of the motor to realize the control of the power of the scooter; As an implementation method, in this embodiment, the light-sensing change signal generated by the rotation of the steering wheel is obtained through the steering wheel rotation sensor, and the rotation action of the steering wheel is converted into a rotation signal in the form of an electrical signal.

[0053] A on / off switch is arranged in the main control circuit board. The process of transmitting the rotation signal to the main control circuit board, the main control circuit board processing and analyzing the signal, and making a control decision on the on / off of the motor is specifically as follows: The steering wheel rotation sensor transmits the rotation signal to the main control circuit board. After the main control circuit board filters and amplifies the signal, it judges whether to start or stop the motor, and then controls the on or off of the on / off switch.

[0054] As an implementation manner, in the motor control steps of this embodiment, when the on-off switch is turned on, the power supply module supplies power to the positive electrode of the motor through the first positive electrode wire, the first positive electrode conductive sheet, the outer and inner rings of the second bearing, the second positive electrode conductive sheet, and the second positive electrode wire. At the same time, the negative electrode of the power supply module participates in forming a power supply circuit for the motor through the first negative electrode wire, the outer and inner rings of the first bearing, the steering tube, and the second negative electrode wire, so that the motor runs; when the on-off switch is turned off, the power supply to the motor stops.

[0055] As an implementation manner, in this embodiment, the power supply module supplies power to the motor and the main control circuit board respectively. The positive electrode of the power supply module also supplies power to the positive electrode input end of the main control circuit board through the third positive electrode wire. The negative electrode of the power supply module is connected to the negative electrode input end of the main control circuit board through the second negative electrode wire, and electrical isolation is achieved between the first bearing and the second bearing through an insulating sleeve to ensure electrical safety during the power supply process.

[0056] As an implementation manner, in this embodiment, when the steering wheel rotates, it drives the steering tube to rotate. The steering tube drives the motor to rotate synchronously through the front fork connected thereto to achieve 360-degree steering, and the second bearing rotates synchronously with the steering tube, driving the second positive electrode wire connected thereto to rotate synchronously, avoiding wire entanglement.

[0057] The control method for the 360-degree steering device of the electric scooter based on light-sensing transmission in this embodiment relies on a specific power supply device for the scooter. Its core lies in using a steering wheel rotation sensor to convert the light-sensing change of the steering wheel rotation into an electrical signal. After receiving the signal, the main control circuit board performs filtering and amplification processing, and controls the on-off of the motor according to the processing result.

[0058] In terms of motor control, the on-off switch determines the power supply state of the motor, and the power supply module provides positive and negative power supplies for the motor through specific wires and conductive sheets. At the same time, the power supply module also supplies power to the main control circuit board, and ensures electrical safety through an insulating sleeve.

[0059] During steering, the steering wheel drives the steering tube, and the motor rotates synchronously through the front fork to achieve 360-degree steering. The second bearing rotates synchronously to drive the second positive electrode wire, avoiding wire entanglement. Each link of this control method cooperates closely to effectively achieve precise steering and stable operation of the electric scooter.

[0060] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
