Description

Technical Field

[0001] This application relates to the field of self-balancing scooter technology, and more particularly to a unicycle self-balancing scooter. Background Technology

[0002] In today's society, with the acceleration of urbanization and the increasing demand for convenient personal travel, personal electric vehicles are gradually gaining popularity as a new mode of transportation. Among them, the unicycle, as a personal transportation tool that combines innovative technology and convenience, has broad application prospects for short-distance urban travel and leisure activities due to its unique design and operation.

[0003] Existing self-balancing unicycles often face numerous challenges in design and maintenance, especially in the maintenance and replacement of wheels and drive mechanisms. Most existing structures adopt an integrated design, where the drive mechanism and frame are tightly connected. If any component fails, the entire vehicle often needs to be disassembled, which is not only time-consuming and labor-intensive, but may also damage other components due to improper operation. Furthermore, the complex assembly and connection of multiple components increases manufacturing costs, affects the reliability and maintenance costs of the entire vehicle, and reduces the ease of use and user satisfaction. Summary of the Invention

[0004] The purpose of this application is to provide a unicycle that solves the technical problems of inconvenient maintenance and replacement of wheels and drive mechanisms, complex overall disassembly and high cost in the prior art.

[0005] To achieve this objective, the present application adopts the following technical solution:

[0006] A self-balancing unicycle includes a drive mechanism and a main frame;

[0007] The main frame is connected to the drive mechanism via a connector, which is exposed outside the main frame.

[0008] When the connector is removed, the connection between the main frame and the drive mechanism is broken, causing the drive mechanism to separate from the main frame.

[0009] Furthermore, it also includes a wheel and a housing, the wheel being embedded inside the housing and exposed at the bottom of the housing, a main shaft being provided at the center of the wheel hub, and the drive mechanism including a fixed part and a rotating part, the rotating part being connected to the main shaft of the wheel, and the fixed part being fixedly connected to the side of the rotating part away from the wheel.

[0010] Furthermore, the main frame includes a shock-absorbing structure and a floating plate. The floating plate is connected to the fixed part of the drive mechanism through the connector. A receiving cavity is provided on the side of the floating plate away from the drive mechanism, and a shock-absorbing structure is provided inside the receiving cavity.

[0011] Furthermore, the shock-absorbing structure includes a support rod and a movable rod. The movable rod is embedded in the receiving cavity. The diameter of the support rod is smaller than that of the movable rod, and one end of the support rod extends into the movable rod and slides with the movable rod to form a telescopic shock-absorbing structure.

[0012] Furthermore, the main frame also includes a guide rail and a slider. The guide rail is disposed on the floating plate and located on both sides of the receiving cavity. One side of the slider is fixedly connected to the floating plate, and the other side is connected to the guide rail, so that the floating plate can move along the guide rail by means of the slider.

[0013] Furthermore, the main frame also includes a vehicle frame, which is fixedly connected to the guide rail, and the vehicle frame has a first through hole at the position corresponding to the connector.

[0014] Furthermore, it also includes a pedal, which includes a connecting part and a contact part. The connecting part is fixedly connected around the bottom of the housing and is fixedly connected to the frame by a fastener. The connecting part is movably connected to the contact part.

[0015] Furthermore, the connecting part extends away from the vehicle frame and is provided with a fixing frame. A movable shaft is provided inside the fixing frame. The movable shaft passes through the center of the contact part, and the contact part can rotate and tilt around the movable shaft at a certain angle.

[0016] Furthermore, the contact portion includes a plurality of third through holes, and a plurality of protrusions are provided on the contact member between two of the third through holes.

[0017] Furthermore, the fixing bracket is provided with a second through hole corresponding to the position of the connector.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] This application's unicycle self-balancing scooter differs from traditional designs. Through a modular design, the drive mechanism is treated as an independent moving part and connected to the main frame via connectors, greatly simplifying the maintenance and replacement process. Specifically, when the drive mechanism needs repair or replacement, the user only needs to remove a few connectors to easily separate the moving part from the main frame, allowing for the removal or replacement of the drive mechanism. This eliminates the need for complex disassembly of the entire scooter, significantly reducing maintenance difficulty and time costs, and avoiding the risk of damage to other components that might result from complete disassembly.

Detailed Implementation

[0028] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0030] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] refer to Figures 1 to 4 This application provides a unicycle self-balancing vehicle, including: a drive mechanism 22 and a main frame; the main frame is connected to the drive mechanism 22 by a connector 3, the connector 3 being exposed outside the outer shell 1; wherein, when the connector 3 is removed, the connection between the main frame and the drive mechanism 22 is disconnected, causing the drive mechanism 22 to separate from the main frame.

[0032] In this embodiment, the drive mechanism 22 is designed as an independent moving part through a modular design and connected to the main frame via a simple connector 3, greatly simplifying the maintenance and replacement process. Simply separating the connector 3 from the through hole disconnects the connection between the main frame 4 and the drive mechanism 22. At this point, the drive mechanism 22 can be easily detached from the main frame for inspection, repair, or replacement. Since the drive mechanism 22 is designed as an independent module, there is no need to disassemble other components on the main frame 4 during maintenance, thus significantly shortening maintenance time and reducing maintenance costs. After maintenance or replacement, the drive mechanism 22 is fixed to the main frame 4 via the connector 3, and the entire unicycle is restored to a usable state. Through modular design, the maintenance of the unicycle becomes simpler and faster, allowing users to easily perform daily maintenance and troubleshooting, thereby improving product reliability and user satisfaction.

[0033] It is worth noting that in this embodiment, the main frame refers to the main structure of the unicycle, supporting components such as the battery pack, control circuit board, and sensors. However, in daily maintenance, the drive mechanism 22 is one of the components most prone to failure. Therefore, the drive mechanism 22 is designed as a quickly replaceable module to improve maintenance efficiency. In this embodiment, the drive mechanism 22 can be a motor, transmission device, or other drive device, depending on the design requirements and performance requirements of the unicycle.

[0034] In one scenario embodiment, the connector 3 can be in the form of a bolt, screw, or clip, depending on the application requirements and design specifications. It can be changed according to the actual usage scenario of the unicycle. For example, in situations involving significant tensile or compressive forces, such as when users frequently engage in high-intensity exercise or use the unicycle on complex terrain, the connector 3 can be made of high-strength bolts or screws. Tightening the threads achieves a secure connection, providing high tensile and shear strength. In situations where weight and space are critical, such as when users prefer lightweight and portable unicycles, the connector 3 can be made of clips. Clips achieve quick connection and separation through elastic deformation and mechanical locking, requiring no tools and improving assembly efficiency. Clip connections also offer good vibration resistance, effectively preventing loosening caused by vibration. In special applications, such as high-temperature or corrosive environments, such as when users use the unicycle in outdoor adventures or industrial environments, the connector 3 needs to consider the heat resistance and corrosion resistance of the materials. At this point, bolts and screws made of stainless steel or special alloy materials can be selected to ensure that the connectors maintain good performance in harsh environments. For snap-fit ​​connections, high-temperature and corrosion-resistant plastics or rubber materials can also be used to adapt to different usage environments. Additionally, a specially designed quick-release mechanism can be employed. For example, connector 3 can be a bolt with a spring-loaded latch; when the latch is pressed, the bolt can easily slide out of the through-hole, achieving quick separation. Simultaneously, spring washers or self-locking nuts are used to ensure that connector 3 does not accidentally loosen during operation.

[0035] In another embodiment, a pressure sensor and a locking device are provided on the side of the connector 3, making the connector 3 more stable when connecting the main frame and the drive mechanism 22, and enabling real-time monitoring of the connection status. Specifically, the pressure sensor detects the pressure value between the connector 3 and the through hole. When the pressure value is lower than a preset threshold, a warning signal is issued to prompt the user to check and tighten it. In addition, the locking device can automatically lock after the connector 3 is inserted into the through hole to prevent accidental loosening, thereby improving the safety of the unicycle during operation.

[0036] In summary, the unicycle self-balancing vehicle of this embodiment, through its innovative modular design, not only achieves independent maintenance of the wheel 21 and the drive mechanism 22 in terms of structure, improving the convenience of use for users, but also enhances the maintainability of the product, extends the service life of the product, and reduces the long-term costs for users.

[0037] In one embodiment, the system further includes a wheel 21 and a housing 1. The wheel 21 is embedded inside the housing 1 and exposed at the bottom of the housing 1. A main shaft is provided at the center of the hub 211 of the wheel 21. The drive mechanism 22 includes a fixed part 221 and a rotating part 222. The rotating part 222 is connected to the main shaft of the wheel 21. The fixed part 221 is fixedly connected to the side of the rotating part 222 away from the wheel 21.

[0038] In this embodiment, the vehicle includes a wheel 21 and a housing 1. First, the housing 1 is removed from the main frame 4. This step can be achieved by loosening the fasteners on the housing 1. After the housing 1 is removed, the internal drive mechanism 22 and the main frame 4 are exposed. The wheel 21 is embedded inside the housing 1 and exposed at the bottom, allowing the vehicle to maintain balance and steer flexibly. A main shaft is centrally located at the hub 211 of the wheel 21. The drive mechanism 22 includes a fixed part 221 and a rotating part 222. The rotating part 222 is connected to the main shaft of the wheel 21 and is responsible for transmitting power and controlling the vehicle's movement, such as acceleration and braking. The fixed part 221 is fixedly connected to one side of the rotating part 222 to ensure the stability and reliability of the drive mechanism 22. The main frame is the supporting structure of the entire vehicle and is connected to the fixed part 221 via multiple connectors 3. The connectors 3 are arranged in a ring around the main shaft of the wheel 21 around the fixed part 221, and these connectors 3 pass through the through holes in the outer shell 1 and are exposed on the outside of the outer shell 1. This design allows the connectors 3 to directly contact the outside of the outer shell 1, which is convenient for users to operate and maintain. Specifically, when the unicycle needs routine maintenance or parts replacement, users do not need professional disassembly tools. They can quickly separate the moving part (i.e., the wheel 21 and the drive mechanism 22 as a whole) from the main frame with simple operations. This design greatly simplifies the maintenance process, reduces the user's learning cost, and also reduces the risk of secondary damage caused by improper maintenance.

[0039] In another embodiment, two slots are provided on each side of the main frame to secure the outer shell 1. This design makes the installation and removal of the outer shell 1 more convenient. Specifically, buckles are provided on both sides of the outer shell 1. When the outer shell 1 needs to be removed, simply pull the buckles out of the slots on the main frame, and the outer shell 1 can be easily separated from the main frame, simplifying the disassembly process and ensuring the accuracy and stability of the outer shell 1 during reinstallation.

[0040] In another embodiment, the system can monitor vehicle status, user posture, and the surrounding environment in real time, achieving precise balance control and intelligent safety protection through a preset algorithm included in the built-in chip. For example, when it detects that the user is about to lose balance, it can quickly adjust the driving force to help the user regain stability; when encountering obstacles or dangerous situations, it can automatically decelerate or brake to avoid collisions and accidents. Specifically, the expression of the preset algorithm is: F adj =K p *(θ target -θ current )+K d *(ω target -ω current )+K i *∫(θ target -θ current In this expression, F )dt, adj This represents the driving force that needs adjustment to restore or maintain balance. K p K d K i These are the proportional, derivative, and integral gain coefficients, which together determine the system's response speed and stability. θ target and ω target These are the target tilt angle and the target angular velocity, determined by the vehicle's preset balance state and user input (such as body tilt); θ current and ω current The measured tilt angle and angular velocity are acquired in real time using built-in sensors such as gyroscopes and accelerometers. This embodiment utilizes a built-in sensor system, including gyroscopes, accelerometers, and magnetometers, to monitor the vehicle and user's motion status in real time. Sensor data is sent to a built-in chip for processing, and the chip calculates the optimal driving force adjustment value based on a preset algorithm to ensure vehicle stability and safety.

[0041] In one embodiment, reference Figure 3 and Figure 4 The main frame includes a shock-absorbing structure and a floating plate 41. The floating plate 41 is connected to the fixing part 221 of the drive mechanism 22 through the connector 3. The floating plate 41 has a receiving cavity 42 on the side away from the drive mechanism 22, and the shock-absorbing structure is provided in the receiving cavity 42.

[0042] In this embodiment, a shock-absorbing structure and a floating plate 41 are incorporated into the design of the main frame, which effectively absorbs vibrations and impacts during riding and provides users with a smoother riding experience. Specifically, the floating plate 41, as a key component connecting the main frame and the drive mechanism 22, cleverly integrates a shock-absorbing mechanism. The floating plate 41 is tightly connected to the fixed part 221 of the drive mechanism 22 via connectors 3. These connectors 3 not only ensure the stability of the structure but also allow the floating plate 41 to be finely adjusted within a certain range to adapt to vibration changes under different road conditions. This fine-tuning mechanism, combined with the use of the shock-absorbing structure, greatly reduces the impact of uneven road surfaces on the rider. The shock-absorbing structure is located in the receiving cavity 42 in front of the floating plate 41 and can be made of highly elastic materials, hydraulic dampers, etc., to achieve effective absorption and conversion of vibrations. When the unicycle travels on uneven roads, the shock-absorbing structure can quickly respond and absorb the impact force from the ground, converting it into heat energy or other forms of energy to dissipate, thereby protecting the delicate components inside the vehicle from damage and reducing the physical burden on the rider. In complex and ever-changing road conditions, the shock absorption structure can reduce the shaking and swaying of the vehicle caused by vibration, allowing the vehicle to maintain a more stable riding posture. This not only helps to improve the rider's confidence and sense of security, but also provides the rider with more reaction time and control space in emergency situations, thereby effectively avoiding accidents.

[0043] In one embodiment, the shock-absorbing structure includes a support rod 431 and a movable rod 432. The movable rod 432 is embedded in the receiving cavity 42. The diameter of the support rod 431 is smaller than that of the movable rod 432, and one end of the support rod 431 extends into the movable rod 432 and slides in cooperation with the movable rod 432 to form a telescopic shock-absorbing structure.

[0044] In this embodiment, the combination of support rod 431 and movable rod 432 constitutes a highly efficient and flexible shock absorption system. Support rod 431, as the fixed part 221, has a smaller diameter to easily extend into movable rod 432 and slide to achieve relative movement between them. This not only ensures the compactness of the shock absorption structure but also effectively utilizes space, making the entire unicycle structure more compact and lightweight. When the unicycle travels on uneven surfaces, the impact force from the ground first acts on movable rod 432. Due to the gap and sliding fit between movable rod 432 and support rod 431, this impact force is converted into sliding motion of movable rod 432 relative to support rod 431. During sliding, damping materials or springs inside movable rod 432 gradually dissipate this impact energy, thereby effectively absorbing and mitigating vibration. Furthermore, the sliding fit between movable rod 432 and support rod 431 also has a damping effect, which can slow down the sliding speed of movable rod 432 to a certain extent, making the shock absorption process smoother and more controllable. This design not only improves shock absorption but also reduces noise and discomfort caused by vibration, providing users with a more comfortable riding experience.

[0045] In one embodiment, the main frame further includes a guide rail 44 and a slider 45. The guide rail 44 is disposed on the floating plate 41 and located on both sides of the receiving cavity 42. One side of the slider 45 is fixedly connected to the floating plate 41, and the other side is connected to the guide rail 44, so that the floating plate 41 can move along the guide rail 44 via the slider 45.

[0046] In this embodiment, the guide rail 44, serving as a guide for the movement of the floating plate 41, is positioned on both sides of the receiving cavity 42. This ensures that the floating plate 41 can move smoothly along a predetermined trajectory when impacted, preventing structural damage or performance degradation due to directional deviation. The slider 45 is firmly fixed to the floating plate 41 on one side by a fastening device, while the other side is tightly fitted to the guide rail 44, forming a low-friction, high-stability sliding connection. The slider 45 is designed with shock absorption in mind, incorporating lubricating materials and shock-absorbing elements to reduce friction and noise during sliding, further enhancing the shock absorption effect. When the floating plate 41 is impacted by the road surface, the slider 45 slides slightly along the guide rail 44. During this process, damping materials or springs in the shock-absorbing structure function, converting the impact energy into heat or other forms of energy to dissipate, effectively protecting the vehicle and rider's safety. Furthermore, the combined design of the guide rail 44 and slider 45 enhances the adaptability of the unicycle. When faced with different road conditions, the floating plate 41 can make fine adjustments through the cooperation of the guide rail 44 and the slider 45 to adapt to the undulations and changes in the road surface. This adaptive adjustment mechanism not only improves the vehicle's riding stability but also provides users with a more comfortable and safer riding experience. Whether on flat city roads or rugged mountain trails, the unicycle demonstrates its excellent performance and reliability.

[0047] In one embodiment, the main frame further includes a frame 46, which is fixedly connected to the guide rail 44, and the frame 46 is provided with a first through hole 461 corresponding to the position of the connector 3.

[0048] In this embodiment, the frame 46 serves as the basic support structure of the main frame. The frame 46 and the guide rail 44 are tightly connected by the connector 3, ensuring the rigidity and stability of the entire main frame. This robust connection not only effectively resists impacts and torsional forces from the road surface but also maintains the integrity and consistency of the structure during vehicle operation. The frame 46 is provided with a first through hole 461 corresponding to the connector 3. In this embodiment, the connector 3 can be removed through the first through hole 461, for example, by using a corresponding tool to pass through the first through hole 461 and connect to the connector 3, thereby achieving a detachable connection between the frame 46 and the drive mechanism 22. This design not only facilitates the assembly and maintenance of the unicycle but also improves the replaceability of parts, reducing maintenance costs and time. At the same time, the setting of the first through hole 461 also fully considers the strength and safety of the structure, ensuring that the frame 46 can provide sufficient support when the connector 3 is subjected to tensile or shear forces, preventing connection failure or structural damage.

[0049] In another embodiment, to further enhance the stability and safety of the unicycle, the frame 46 can also be equipped with reinforcing ribs or support beams. These reinforcing structures can effectively distribute the stress borne by the frame 46, preventing deformation or damage caused by localized stress concentration. The reinforcing ribs or support beams can be arranged along the main stress directions of the frame 46 to form a stable triangular support structure or mesh structure, thereby improving the load-bearing capacity and torsional strength of the entire frame 46. This not only improves the overall performance of the unicycle but also provides users with more reliable and safer riding protection.

[0050] In a specific shock-absorbing structure embodiment, the frame 46 is fixedly connected to the guide rail 44 as the first part, and the slider 45, floating plate 41, wheel 21, drive mechanism 22, and connector 3 are connected as the second part. When the wheel 21 encounters uneven road surfaces or sudden impacts, the second part, as a whole, slides precisely and smoothly along the guide rail 44 via the slider 45. This design cleverly utilizes the principles of leverage and sliding friction to disperse and convert the impact force on the wheel 21 into sliding motion. Simultaneously, the damping elements in the shock-absorbing structure respond quickly, effectively absorbing and dissipating this impact energy. During the sliding process, the floating plate 41, as a key component, not only bears the weight of the wheel 21 and drive mechanism 22 but also helps the vehicle adapt to complex and changing road conditions through its flexible mobility. The close cooperation between the floating plate 41 and the slider 45 ensures smooth sliding and maximizes the shock absorption effect. Furthermore, the design of the floating plate 41 also considers weight distribution and aerodynamic factors, making the entire unicycle more stable and efficient during operation. To further enhance shock absorption, the wheel 21 can also employ advanced materials and structural designs. For example, the wheel hub 211 can incorporate built-in shock-absorbing springs or shock-absorbing rubber to provide additional cushioning when the wheel 21 is subjected to impact. Simultaneously, the tires of the wheel 21 can be made of highly elastic, wear-resistant materials to improve the vehicle's grip and shock absorption performance.

[0051] In one embodiment, the vehicle also includes a pedal 5, which includes a connecting portion 51 and a contact portion 52. The connecting portion 51 is fixedly connected around the bottom of the housing 1 and is fixedly connected to the frame 46 by a fastener. The connecting portion 51 is movably connected to the contact portion 52.

[0052] In this embodiment, the pedal 5, as a key component in direct contact with the user, provides a stable connection between the pedal 5 and the outer shell 1 and the frame 46, while offering a flexible and comfortable pedaling experience. Specifically, the connecting part 51 of the pedal 5 is fixedly connected around the bottom of the outer shell 1. This wraparound design not only enhances the connection strength between the pedal 5 and the outer shell 1 but also makes the entire structure more compact and aesthetically pleasing. Simultaneously, the connecting part 51 is tightly connected to the frame 46 by high-strength fasteners, ensuring the stability of the pedal 5 during vehicle operation and preventing loosening or detachment due to vibration or impact. A movable connection is used between the connecting part 51 and the contact part 52. This design allows the contact part 52 to be finely adjusted according to the user's pedaling force and angle, thus providing a more ergonomic pedaling experience. Regardless of the user's foot size, the contact part 52 can adaptively adjust to provide optimal support and comfort. Furthermore, the movable connection also has a certain shock absorption effect, absorbing and mitigating the impact from the road surface to a certain extent, further enhancing the user's riding experience.

[0053] In one embodiment, the connecting portion 51 extends away from the frame 46 and is provided with a fixing frame 511. The fixing frame 511 is provided with a movable shaft 512, which passes through the center of the contact portion 52. The contact portion 52 can rotate and tilt around the movable shaft 512 at a certain angle.

[0054] In this embodiment, the connecting part 51 extends away from the frame 46 to form a cleverly designed fixing bracket 511. The fixing bracket 511 not only stably supports the entire pedal 5 structure but also houses a movable shaft 512. The movable shaft 512 passes through the center of the contact part 52, providing a stable center of rotation for its movement. During use, the user can easily adjust the pedal angle and pressure according to personal habits or changes in road conditions. The rotation and tilting motion of the contact part 52 around the movable shaft 512 not only improves riding comfort but also enhances the vehicle's handling and stability under different road conditions. This design fully considers ergonomic principles, ensuring that the pedal 5 closely conforms to the user's foot contours, reducing fatigue from long-distance riding. Simultaneously, the introduction of the movable shaft 512 increases the durability of the pedal 5 system, as the rotation and tilting motion disperses stress, preventing wear or damage caused by excessive force at a single point. Furthermore, the combination of the fixing bracket 511 and the movable shaft 512 also provides a certain degree of shock absorption, mitigating vibrations from the road surface and providing a smoother riding experience for the user. To further optimize the performance of pedal 5, it is also possible to add lubricating material between the fixed frame 511 and the movable shaft 512 to reduce frictional resistance during rotation and tilting, thereby improving the smoothness and responsiveness of pedal 5.

[0055] In one embodiment, the contact portion 52 includes a plurality of third through holes, and a plurality of protrusions are provided on the contact member between two of the third through holes. The fixing bracket 511 is provided with a second through hole corresponding to the position of the connector 3.

[0056] In this embodiment, multiple through holes are provided on the contact portion 52. These through holes not only reduce the overall weight of the pedal 5, making riding lighter, but also increase the breathability and drainage of the pedal 5, keeping the user's feet dry even when riding in the rain. Between the through holes, several protrusions are carefully arranged on the contact member. These protrusions increase friction, ensuring that the rider can pedal stably under various road conditions. The protrusion design not only improves the comfort of the foot feel but also enhances the durability of the pedal 5, reducing wear caused by prolonged use. At the same time, a second through hole is provided on the fixing bracket 511 at the position corresponding to the connector 3. The function of the second through hole is the same as that of the first through hole 461; both can be accessed through the corresponding tool to release the connector 3.

[0057] In another embodiment, to further enhance the overall performance and user experience of the unicycle, components such as the frame 46, shock absorption structure, and pedals 5 can be intelligently upgraded. For example, by integrating sensors and a control system, key parameters such as wheel speed, steering angle, and vehicle posture can be monitored in real time, and parameters such as shock absorption and power output can be automatically adjusted according to road conditions and user intentions to achieve more intelligent and precise riding control. Simultaneously, wireless communication technologies such as Bluetooth and Wi-Fi can be used to connect the unicycle to smart devices such as smartphones and smartwatches, enabling remote control, status monitoring, and data analysis, providing users with a more convenient and comprehensive riding experience.

[0058] In one embodiment, a battery pack 6 is also included, which is fixed at opposite ends of the main frame to provide the power required for the drive mechanism 22.

[0059] In this embodiment, the battery pack 6 is fixed at opposite ends of the main frame, a layout that helps achieve a balanced weight distribution for the vehicle. Placing the battery pack 6 symmetrically on the main frame effectively lowers the vehicle's center of gravity, improves driving stability, and reduces the risk of tipping over due to a shift in the center of gravity. Simultaneously, the balanced weight distribution also helps optimize the unicycle's handling performance, allowing users to experience smoother and more precise responses during turns, acceleration, and deceleration. Furthermore, to facilitate user charging and maintenance of the battery pack 6, this embodiment also features a convenient charging interface and battery replacement mechanism. The charging interface is located on one side of the battery pack 6; users simply need to insert the charger into the interface to begin charging. The battery replacement mechanism allows users to quickly replace the battery pack 6 with a spare when the battery is depleted, eliminating the need to wait for a long charging process and significantly improving efficiency.
