Description

Technical Field

[0001] This application relates to the field of two-wheeled vehicle technology, and more particularly to a two-wheeled vehicle. Background Technology

[0002] Two-wheeled vehicles, including electric bicycles and motorcycles, play a vital role in urban short-distance commuting and logistics delivery due to their lightweight, economical, and flexible advantages. As an indispensable component of two-wheeled vehicles, the support frame's core function is to provide ground contact support when the vehicle is stationary, effectively preventing tipping due to imbalance. To enhance user experience, electrically retractable support frames have been introduced, allowing for automatic retraction via user operation such as turning the throttle, thus meeting intelligent usage requirements.

[0003] However, the electric telescopic support components using related technologies have problems such as slow deployment speed and delayed positioning, posing a risk of vehicle tipping over and poor safety. Summary of the Invention

[0004] In order to overcome the above-mentioned defects in related technologies, the purpose of this application is to provide a two-wheeled vehicle. This application shortens the extension and retraction time by combining pre-rotation and extension, which is beneficial to improving parking safety.

[0005] This application provides a two-wheeled vehicle, including a control component, a detection component, and a support component. The control component includes a controller, and the detection component includes a vehicle speed sensor, which is communicatively connected to the controller. The support component includes at least one support portion and a drive member, which is communicatively connected to the controller. The drive member is connected to the support portion and is used to drive the support portion to rotate and / or extend or shorten. The support portion has a retracted position, a pre-supported position, and a supported position. When the speed of the two-wheeled vehicle is less than or equal to a first threshold, the controller controls the drive member to drive the support portion to rotate from the retracted position to the pre-supported position. When the speed of the two-wheeled vehicle is less than or equal to a second threshold, the controller further controls the drive member to drive the support portion to rotate from the pre-supported position to the supported position. The controller also controls the drive member to extend the support portion.

[0006] In one possible implementation, when the support is in the pre-support position, the length of the support is H1, which is less than the support distance H2; wherein, the support distance H2 is the distance between the bottom ground contact point of the support and the connection point Q between the support and the frame when the two-wheeled vehicle is in the parked state and the support is in the support position.

[0007] In one possible implementation, a horizontal plane P1 perpendicular to the height direction of the two-wheeled vehicle is defined, a straight line L1 passing through the connection point Q and perpendicular to the horizontal plane P1 is defined, and a straight line L2 extending along the support is defined.

[0008] When the support is in the pre-support position, the support is located behind the straight line L1;

[0009] When the support is in the support position, the support is perpendicular to the horizontal plane, or the support is located in front of the straight line L1.

[0010] In one possible implementation, when the support is in the pre-support position, the support is located in front of the straight line L2; the angle between the straight line L1 and the straight line L2 is greater than or equal to 0° and less than or equal to 10°.

[0011] In one possible implementation, the first threshold is greater than or equal to 3 km / h and less than or equal to 5 km / h; the second threshold is greater than or equal to 0 km / h and less than or equal to 3 km / h.

[0012] In one possible implementation, the support portion includes a first support portion and a second support portion distributed along the width direction of the two-wheeled vehicle, wherein both the first support portion and the second support portion include a first part and a second part connected to each other;

[0013] The driving component includes a first driving motor, a second driving motor, a third driving motor, and a fourth driving motor. The output ends of the first driving motor and the second driving motor are connected to the first part for transmission and are used to control the rotation of the support part. The third driving motor and the fourth driving motor are connected to the second part for transmission and are used to drive the second part to move closer to or further away from the first part relative to the first part.

[0014] In one possible implementation, both the third drive motor and the fourth drive motor are communicatively connected to the controller, which is also used to detect the torque of the third drive motor and the fourth drive motor.

[0015] When the support part is in the support position, if the torque of the third drive motor and / or the fourth drive motor is less than a preset value, the controller controls the third drive motor and / or the fourth drive motor to drive the corresponding second part to continue to extend.

[0016] In one possible implementation, a push rod and a movable plate are provided between the first part and the second part. The output end of the third drive motor or the output end of the fourth drive motor is connected to the push rod. The movable plate is fixedly connected to the second part. The third drive motor or the fourth drive motor drives the movable plate to move through the push rod, so that the second part moves closer to or further away from the first part.

[0017] In one possible implementation, the support portion further includes a roller disposed at the end of the second portion away from the first portion.

[0018] In one possible implementation, the output ends of the first drive motor and the second drive motor are provided with a first gear, and the first part is provided with a second gear, wherein the first gear meshes with the second gear.

[0019] This application provides a two-wheeled vehicle, including a control component, a detection component, and a support component. The control component includes a controller, and the detection component includes a vehicle speed sensor, which is communicatively connected to the controller. The support component includes at least one support portion and a drive member, which is communicatively connected to the controller. The drive member is connected to the support portion and is used to rotate and / or extend or retract the support portion. The support portion has a retracted position, a pre-supported position, and a supported position. When the speed of the two-wheeled vehicle is less than or equal to a first threshold, the controller controls the drive member to rotate the support portion from the retracted position to the pre-supported position. When the speed of the two-wheeled vehicle is less than or equal to a second threshold, the controller further controls the drive member to rotate the support portion from the pre-supported position to the supported position. The controller also controls the drive member to extend the support portion. This application, by combining pre-rotation and extension / retraction in the supported position, shortens the time required for extension and retraction, thus improving parking safety.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0043] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] As described in the background section, the electric telescopic support components in the related technologies have problems such as slow deployment speed and delayed positioning, which pose a risk of vehicle tipping over and poor safety.

[0045] In view of this, the present application aims to provide a two-wheeled vehicle that shortens the extension and retraction time by combining pre-rotation and extension and retraction in the support position, thereby improving parking safety.

[0046] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of the embodiments of this application, the length direction of the two-wheeled vehicle refers to the front-to-back direction shown in the figures, where the front side can be the forward direction of the two-wheeled vehicle; the width direction of the two-wheeled vehicle refers to the left-to-right direction shown in the figures; and the height direction of the two-wheeled vehicle refers to the up-down direction shown in the figures.

[0047] Please refer to Figures 1-5This embodiment provides a two-wheeled vehicle, which can be a two-wheeled motorcycle, a two-wheeled electric vehicle, or a two-wheeled bicycle, etc. The two-wheeled vehicle of this embodiment includes a frame 10 and a body cover 20 mounted on the frame 10. Exemplarily, the frame 10 includes a mounting bracket 11 and a main frame 12. The mounting bracket 11 is at least partially located below the main frame 12. The mounting bracket 11 is generally horizontally positioned to provide a base for the installation of other parts. The main frame 12 can be fixed to the mounting bracket 11 by welding, fastener connection, or other methods. The body cover 20 can be applied to the mounting bracket 11 and the main frame 12 to conceal the frame 10 and improve the aesthetics of the two-wheeled vehicle. The body cover 20 can be fixedly connected to the frame 10 by snap-fit, fastener connection, or other methods. The two-wheeled vehicle also includes two wheels 30 respectively located on the front and rear sides of the frame 10. The frame 10 may also be equipped with a motor, battery and other parts for driving the wheels 30 to rotate. The battery is used to provide power to the motor, and the motor can drive at least one wheel 30 to rotate, thereby driving the two-wheeled vehicle to travel on the ground.

[0048] Please continue to refer to Figure 4 In this embodiment, the two-wheeled vehicle also includes a control component and a detection component 50. Both the control component and the detection component 50 can be mounted on the frame 10, and their specific positions can be selected as needed. The control component is used to realize functions such as vehicle signal acquisition, logic judgment, power control, power distribution protection, human-machine interaction, and safety protection. The control component includes a controller 40, which can be a vehicle control unit (VCU) and / or a microcontroller unit (MCU), etc. The controller 40 is the control core of the two-wheeled vehicle, and the aforementioned motor, battery, detection component 50, etc., are all communicatively connected to the controller 40. The detection component 50 is used to detect various parameters of the two-wheeled vehicle during use, and the detection component 50 can be specifically configured as needed. For example, the detection component 50 may include a vehicle speed sensor 51, which can monitor the vehicle speed in real time. The detection component 50 may also include a tilt sensor 52, which can monitor the tilt state of the two-wheeled vehicle in real time. In other possible implementations, the detection component 50 may also include a stress sensor 53, a distance sensor (including a first distance sensor 54 and a second distance sensor 55, corresponding to the first support portion 611 and the second support portion 612, respectively), etc.

[0049] Please continue to refer to Figures 1-5 In this embodiment, the frame 10 is also provided with a support component 60, which is used to contact and abut against the ground when the two-wheeled vehicle is parked, thereby keeping the two-wheeled vehicle in a stable parking state. The support component 60 can contact the ground directly through its bottom plane, or through an anti-slip pad provided at the bottom of the support part 61.

[0050] like Figure 6 As shown, the support assembly 60 includes at least one support portion 61. It is understood that the support portion 61 is the part that directly contacts the ground when the two-wheeled vehicle is parked. The number of support portions 61 can be set according to needs. For example, the support portion 61 can be provided only on one side in the width direction of the two-wheeled vehicle. When the two-wheeled vehicle is parked, it can be slightly tilted towards the side where the support portion 61 is located, and the support portion 61 stably supports the two-wheeled vehicle. Alternatively, as... Figure 2 As shown, a support part 61 can be provided on each side of the two-wheeled vehicle in the width direction. For ease of distinction, the two support parts 61 are referred to as the first support part 611 and the second support part 612. When the two-wheeled vehicle is parked, the first support part 611 and the second support part 612 can respectively contact and abut against the ground from both sides of the frame 10, thereby keeping the two-wheeled vehicle stable. (It should be noted that if the following description refers to the provision of only one support part 61, this support part 61 can be the first support part 611).

[0051] Please continue to refer to Figure 6 In order to improve the intelligence level of the two-wheeled vehicle, the support component 60 may also include a drive component 62, which is connected to the support part 61 in a transmission manner, and the drive component 62 can at least drive the support part 61 to rotate around the connection point Q between the support part 61 and the frame 10, thereby raising or lowering the support part 61.

[0052] In this embodiment, the drive unit 62 is communicatively connected to the controller 40. In some possible implementations, a button may be provided, which can be electrically connected to the controller 40 for inputting control commands to the controller 40. The controller 40 is configured to control the drive unit 62 to drive the support unit 61 to perform corresponding retraction or lowering actions based on the retraction or lowering command input by the button.

[0053] As another alternative implementation, the timing of raising and lowering the support 61 can be intelligently determined by the detection data of the detection component 50. The controller 40 is configured to intelligently determine the timing of raising or lowering the support 61 based on the detection data output by the detection component 50, and control the drive component 62 accordingly to achieve intelligent and seamless operation of the support 61.

[0054] Specifically, in the first embodiment, the detection component 50 includes a vehicle speed sensor 51. When the two-wheeled vehicle is in motion, the vehicle speed sensor 51 continuously acquires the vehicle speed and sends the corresponding signal to the controller 40. The controller 40 compares the vehicle speed with a preset first threshold and a second threshold. When the vehicle speed is less than or equal to the first threshold, the controller controls the support part 61 to rotate from the fully retracted position to a pre-deployed pre-support position. When the vehicle speed is less than or equal to the second threshold, the controller 40 further controls the drive component 62 to rotate the support part 61 from the pre-support position to the support position, so that the support part 61 contacts the ground, thereby providing stable support for the two-wheeled vehicle. It is understood that the aforementioned first threshold is greater than the second threshold.

[0055] Specifically, as another alternative implementation, the detection component includes a tilt sensor 52, which continuously acquires the tilt angle of the two-wheeled vehicle and sends the corresponding signal to the controller 40. The controller 40 compares the tilt angle with a preset tilt angle threshold. When the tilt angle is greater than the tilt angle threshold, the support 61 is controlled to rotate and lower.

[0056] Specifically, the driving component 62 includes a first drive motor 621, which is drivenly connected to the first support portion 611. Specifically, the first drive motor 621 can drive the first support portion 611 to rotate relative to the frame 10. For ease of reference, various actions of issuing control commands to raise or lower the support portion 61 are referred to as operational actions. It can be understood that operational actions in this embodiment include both actively issuing raise or lower commands via buttons and automatically determining based on parameters from the sensor 50. For example, the output end of the first drive motor 621 can be connected to the first support portion 611 via a gear transmission mechanism to convert the motor's rotational motion into the rotation of the first support portion 611; alternatively, the output end of the first drive motor 621 can also be connected to the first support portion 611 via a linkage mechanism or a cam mechanism to achieve complex motion trajectories or specific raising postures.

[0057] The driving component 62 also includes a second driving motor 622, which is drivingly connected to the second support portion 612. The specific connection structure between the second driving motor 622 and the second support portion 612 can be referred to the connection structure between the first driving motor 621 and the first support portion 611 described above, and will not be repeated in this embodiment.

[0058] In this embodiment, both the first drive motor 621 and the second drive motor 622 are mounted on the frame 10 and fixedly connected to it. The specific connection method can be determined as needed, such as using fasteners or snap-fit ​​connections. The first drive motor 621 and the second drive motor 622 can operate independently, thereby driving the first support portion 611 and the second support portion 612 to rotate independently. For example, when the two-wheeled vehicle tilts towards the first support portion 611, the first drive motor 621 can drive the first support portion 611 to rotate and lower, while the second drive motor 622 can be temporarily deactivated to keep the second support portion 612 stationary.

[0059] Please continue to refer to Figure 4 In this embodiment, the drive unit 62 can be communicatively connected to the controller 40. The controller 40 can send corresponding instructions to the drive unit 62 based on the detection signal of the detection component 50, thereby realizing the intelligent control of the two-wheeled vehicle.

[0060] In some possible implementations, the controller 40 can control the drive component 62 of the support assembly 60 to perform corresponding actions based on the vehicle speed detected by the vehicle speed sensor 51. By setting the mapping relationship between the vehicle speed and the opening parameters of the support assembly 60 (such as opening angle and opening length), the opening range of the support 61 can be matched with the vehicle speed, thereby reducing or eliminating the time and effort required for manual operation and improving parking efficiency.

[0061] For example, when the vehicle speed is less than or equal to a first threshold, the drive member 62 can be controlled to rotate the support part 61 from the retracted position to the pre-support position. When the vehicle speed is less than or equal to a second threshold, the drive member 62 can be further controlled to rotate the support part 61 from the pre-support position to the support position. At the same time, the drive member 62 can be controlled to extend the support part 61, so that the two-wheeled vehicle can be smoothly supported on the ground and the parking time can be shortened.

[0062] In other possible implementations, the controller 40 may control the drive component 62 of the support assembly 60 to perform corresponding actions based on the tilt state of the two-wheeled vehicle detected by the tilt sensor 52, so as to dynamically match the parking needs under complex terrain, reduce the difficulty of parking operation, and improve intelligent parking capability and parking stability.

[0063] For example, after the two-wheeled vehicle is parked, the first tilt angle of the two-wheeled vehicle can be detected. If the angle value exceeds the preset tilt angle range, the drive component 62 is controlled to drive the first support part 611 or the second support part 612 to extend, so that the second tilt angle of the two-wheeled vehicle after adjustment is within the preset tilt angle range, thereby obtaining a more stable parking posture.

[0064] As previously described, this embodiment provides a support component capable of automatically controlling the raising and lowering of the support section based on button or sensor detection information. However, traditional support components, in order to achieve a stable connection between the two-wheeled vehicle and the ground and prevent support failure due to the weight of the two-wheeled vehicle itself, require the support component to rotate more than 90 degrees in the supported state. An elastic element provides a pre-tightening force that has the opposite effect to the rotation. This setup is difficult to work effectively in automatic rotation scenarios. Furthermore, it may easily rub against the ground when the two-wheeled vehicle starts, generating friction noise and potentially causing safety accidents.

[0065] In some possible implementations, such as Figures 7-10 As shown, the support assembly 60 in this embodiment includes a support part 61 and a drive member 62. The support part 61 is rotatably connected to the frame 10 through a connection point Q. The support part 61 includes a retracted state (e.g., Figure 9 and Figure 10 (as shown) and support status (as shown) Figure 7 (As shown). The drive unit 62 is communicatively connected to the controller 40 and drively connected to the support unit 61. Under the control of the controller 40, the drive unit 62 can drive the support unit 61 to switch between a retracted state and a supported state. For example, when the two-wheeled vehicle is parked, the support unit 61 rotates at a certain angle under the drive of the drive unit 62 and contacts the ground, thereby providing support for the two-wheeled vehicle. The support unit 61 then switches from the retracted state to the supported state.

[0066] Furthermore, to ensure effective support of the two-wheeled vehicle by the support component in the supported state and to prevent instability under the weight of the vehicle, the support assembly 60 in this embodiment also includes a locking member 63. The locking member 63 is communicatively connected to the controller 40. When the support component 61 is in the supported state, the locking member 63 can lock or unlock the support component 61 under the control of the controller 40. For example, the locking member 63 can be a mechanical latch, driven by the controller 40. When the controller 40 issues a locking command, the locking member 63 fixes the support component 61 in the lowered position to prevent it from being accidentally retracted. When the controller 40 issues an unlocking command, the locking member 63 unlocks the support component 61, allowing it to be retracted. The controller 40 can determine when to lock or unlock the support component 61 based on the state of the two-wheeled vehicle. For example, when the two-wheeled vehicle is parked and the speed is 0, the controller 40 can control the locking member 63 to lock and fix the support part 61. When the two-wheeled vehicle is running, the controller 40 can obtain throttle opening information. When the throttle is turned, the controller 40 first controls the locking member 63 to unlock the support part 61, and then performs the throttle operation. It can be understood that in this embodiment, when the two-wheeled vehicle is parked, the controller 40 can control the locking member 63 to lock and fix the support part 61 to prevent the support part 61 from rotating, thereby maintaining a stable parking posture for the two-wheeled vehicle. When the two-wheeled vehicle is running, the controller 40 can control the locking member 63 to unlock the support part 61. After being subjected to friction from the ground, the support part 61 retracts directly to the rear in the direction of travel of the two-wheeled vehicle, which helps reduce friction noise with the ground and reduces the probability of safety accidents.

[0067] Please continue to refer to Figure 7 Define a horizontal plane P1 perpendicular to the height direction of the two-wheeled vehicle, and define a straight line L1 passing through the connection point and perpendicular to the horizontal plane P1. When the support part 61 is in the support state, the extension direction of the support part 61 is basically the same as that of the straight line L1, or the support part 61 is located behind the straight line L1.

[0068] With the above structure, in this embodiment, when the two-wheeled vehicle is stationary, the support part 61 can be locked by the locking member 63 to keep the two-wheeled vehicle in a stable supported state. When the two-wheeled vehicle starts, the locking member 63 can unlock the support part 61, and the support part 61 will retract directly after being subjected to the reaction force of the ground, which helps to reduce friction noise with the ground and reduce the probability of safety accidents.

[0069] In some examples, such as Figure 8 As shown, the locking member 63 in this embodiment can adopt a normally closed solenoid valve structure. The locking member 63 includes an electromagnetic member 631, a reset member 632, and a locking pin 633. The electromagnetic member 631 is used for communication connection with the controller 40. The electromagnetic member 631 is also drivenly connected to the locking pin 633. The reset member 632 is located between the locking pin 633 and the electromagnetic member 631 and provides a preload force that keeps them apart.

[0070] When the locking member 63 is in the locked state, the locking pin 633, under the action of pre-tightening force, at least partially passes through the support part 61 and the frame 10, so that the locking pin 633 locks the support part 61.

[0071] When the locking member 63 is in the unlocked state, the electromagnetic member 631 attracts the locking pin 633 to disengage from the frame 10, thereby unlocking the locking pin 633 from the support 61.

[0072] Specifically, the electromagnetic component 631 refers to a component capable of generating mechanical force through electromagnetic effects, such as an electromagnet, solenoid valve, or electromagnetic clutch. The electromagnetic component 631 is energized or de-energized by receiving electrical signal commands from the controller 40. The locking pin 633 can be made of a magnetically conductive metal material. When energized, the electromagnetic component 631 generates a magnetic force, attracting the locking pin 633 to move away from the support portion 61, thereby unlocking the support portion 61. When de-energized, the magnetic force generated by the electromagnetic component 631 disappears, and the reset component 632 can abut the locking pin 633 against the support portion 61 to lock the support portion 61. In this embodiment, the connection method between the reset component 632 and the locking pin 633 can be configured as needed; for example, the reset component 632 can be directly fitted onto the locking pin 633, or one end can be fixed to the housing of the locking component 63, and the other end can abut or connect to the side or end of the locking pin 633. This connection ensures that the reset element 632 can effectively transmit its own reset force to the locking pin 633, so that it remains locked under certain conditions.

[0073] In this embodiment, when the two-wheeled vehicle is parked, the controller 40 controls the electromagnetic component 631 to be de-energized or the power supply is insufficient to generate magnetic force. At this time, the pre-action force of the reset component 632 pushes the locking pin 633 towards the support portion 61, thereby achieving mechanical locking of the support portion 61. This design utilizes the inherent characteristics of the reset component 632 to automatically lock in the event of a power outage, ensuring safety when parked.

[0074] When the two-wheeled vehicle starts, the controller 40 detects a start signal (e.g., the vehicle speed sensor 51 detects vehicle speed, throttle input, etc.) and then sends an energizing command to the electromagnetic component 631. After being energized, the electromagnetic component 631 generates sufficient magnetic force to overcome the force of the reset component 632, attracting or pulling the locking pin 633 away from the support part 61. The disengagement of the locking pin 633 releases the support part 61, allowing it to be retracted promptly and preventing friction noise and safety accidents. This structure ensures the speed and reliability of locking and unlocking, significantly improving the safety and user experience when starting and stopping the two-wheeled vehicle.

[0075] Furthermore, the reset member 632 in this embodiment includes a spring (e.g., a helical compression spring), with its two ends connected to an electromagnetic member 631 and a locking pin 633, respectively. The support portion 61 has a locking hole 6114, and the frame 10 has a mating hole. When the locking pin 633 is at least partially located within the locking hole 6114 and the mating hole, the locking member 63 is in a locked state; when the locking pin 633 is outside the mating hole, the locking member 63 is in an unlocked state.

[0076] Specifically, in this embodiment, the two ends of the spring are connected to the electromagnetic component 631 and the locking pin 633, respectively. This connection method ensures that the elastic force of the spring can effectively act on the locking pin 633 and coordinate with the movement of the electromagnetic component 631. For example, one end of the spring can be fixedly connected to the body of the electromagnetic component 631 or its internal fixed structure, while the other end is connected to a specific part of the locking pin 633 via a mechanical connection (e.g., snap-fit, threaded connection, or welding). Another implementation is that one end of the spring is connected to a moving part (such as an armature) of the electromagnetic component 631, and the other end is connected to the locking pin 633, so that when the electromagnetic component 631 is energized and attracted, it directly compresses or stretches the spring, thereby achieving precise movement of the locking pin 633.

[0077] The locking hole 6114 can be a through hole provided on the support 61, used to precisely accommodate the locking pin 633 for mechanical locking. The locking hole 6114 can be designed as a circular hole to mate with the cylindrical locking pin 633, facilitating machining and accurate positioning; or it can be designed as a hole with a guide bevel or chamfer to facilitate the smooth insertion of the locking pin 633, reduce jamming, and improve the smoothness of the locking action. Similarly, the mating hole can be a through hole provided on the bracket 10, used to precisely accommodate the locking pin 633 for mechanical locking. The structure of this hole can be similar to the locking hole 6114 described above, and will not be repeated here. The insertion or withdrawal of the locking pin 633 usually occurs along the axial direction of the locking hole 6114 and the mating hole. When the locking pin 633 is fully inserted into the locking hole 6114 and the mating hole, the support 61 is mechanically fixed, achieving locking; when the locking pin 633 is fully withdrawn from the locking hole 6114 and the mating hole, the support 61 is released, achieving unlocking. In addition, the locking pin 633 can also be designed to enter or leave the locking hole 6114 and the mating hole by rotating or swinging, which will not be described in detail in this embodiment.

[0078] This embodiment significantly improves the accuracy and reliability of locking and unlocking operations of the support part 61 by connecting the two ends of the spring to the electromagnetic component 631 and the locking pin 633 respectively.

[0079] Define another straight line L2 extending along the support 61. For example... Figure 7As shown by the dashed line in the middle, the support portion 61, as an optional implementation, when driven to the supported state, is positioned behind the straight line L1 when viewed along the length of the electric two-wheeler. The angle α between the straight lines L1 and L2 can be set as needed, as long as it allows the two-wheeler to park stably. For example, the angle α between the straight lines L1 and L2 is greater than or equal to 0° and less than or equal to 5°. This angle range defines the specific posture of the support portion 61 when supporting the two-wheeler, where 0° indicates that the support portion 61 is completely perpendicular to the ground, and 5° indicates that the support portion 61 is slightly tilted. When the two-wheeler starts, the support portion 61, after being subjected to the friction force of the ground, can more quickly and smoothly detach from the ground, which helps to reduce friction noise with the ground and reduce the probability of safety accidents.

[0080] In this embodiment, please refer to Figure 4 and Figure 6 The detection component 50 includes a stress sensor 53, which is mounted on the support 61 and near the connection between the support 61 and the drive member 62. When the two-wheeled vehicle moves forward, the support 61 generates a stress trend opposite to the direction of travel of the two-wheeled vehicle. The stress sensor 53 is used to detect the stress trend and sends a sensing signal to the controller 40 based on the detection result of the stress trend.

[0081] Specifically, the stress sensor 53 is a device that converts the mechanical stress borne by an object into a measurable electrical signal. Its implementation can include, but is not limited to, a resistance strain gauge stress sensor 53, which reflects the stress magnitude by measuring changes in the resistance of the strain gauge; or a piezoelectric stress sensor 53, which detects stress by utilizing the characteristic that piezoelectric materials generate electrical charges when subjected to force. The stress sensor 53 is directly mounted on the support 61, ensuring that the sensor can directly contact the solid structure of the support 61. The stress sensor 53 is positioned near the connection between the support 61 and the drive component 62 because this location typically experiences stress concentration during the movement of the support 61. This arrangement enhances the sensor's sensitivity to force changes, allowing it to more quickly capture stress release signals when the two-wheeled vehicle starts and transmit them to the controller 40. Based on this signal, the controller 40 can promptly trigger the locking component 63 to unlock the support 61, thereby preventing the support 61 from failing to retract in time after the two-wheeled vehicle starts, which could cause friction noise with the ground and even lead to safety accidents. This precise and timely detection mechanism significantly improves the intelligence and safety of the two-wheeled vehicle support component 60.

[0082] For example, after receiving a stress value, the stress sensor 53 can compare the stress value with a preset stress value. When the received stress value is greater than the preset stress value, the stress sensor 53 sends a sensing signal to the controller 40. Alternatively, the stress sensor 53 can continuously detect the stress value and compare the stress values ​​at different times. When the stress value at the first time is greater than the stress value at the second time, the stress sensor 53 sends a sensing signal to the controller 40. The controller 40 can then control the drive unit 62 to move the support part 61 from the supported state to the retracted state based on the sensing signal from the stress sensor 53.

[0083] In some examples, the detection component 50 also includes a vehicle speed sensor 51, which may be mounted on the wheel 30. The controller 40 is communicatively connected to the vehicle speed sensor 51, which detects the speed information of the two-wheeled vehicle and sends a sensing signal to the controller 40 based on the detection result.

[0084] Specifically, the vehicle speed sensor 51 is used to monitor the speed of the two-wheeled vehicle in real time. Its function is to provide crucial information on whether the two-wheeled vehicle is in motion, thereby assisting the controller 40 in determining whether the support 61 needs to be unlocked. The vehicle speed sensor 51 can be implemented in various ways. For example, a Hall effect sensor can be used, which calculates the vehicle speed by detecting the pulse signal generated by the rotation of a magnet mounted on the wheel 30; or, a Global Positioning System (GPS) based module can be used to obtain real-time speed data of the two-wheeled vehicle by receiving satellite signals. Alternatively, an inductive sensor can be used to measure the rotational speed by detecting the toothed structure on the wheel 30 or transmission components, and then calculate the vehicle speed.

[0085] For example, in this embodiment, when the two-wheeled vehicle starts, the vehicle speed sensor 51 can detect changes in the vehicle's speed in real time. When the vehicle speed is less than a first threshold (e.g., 3 km / h), the vehicle speed sensor 51 may temporarily not send a sensing signal to the controller 40 to avoid the support part 61 being retracted due to driver error. When the vehicle speed is greater than the first threshold, the vehicle speed sensor 51 sends a sensing signal to the controller 40. The controller 40 can then control the drive unit 62 to move the support part 61 from the supported state to the retracted state based on the sensing signal from the vehicle speed sensor 51.

[0086] In some examples, the detection component 50 also includes a tilt sensor 52, which may be mounted on the frame 10 of the two-wheeled vehicle. The controller 40 is communicatively connected to the tilt sensor 52, which detects the tilt information of the two-wheeled vehicle and sends a sensing signal to the controller 40 based on the detection result of the tilt information.

[0087] Specifically, the tilt sensor 52 is used to detect the tilt angle of the two-wheeled vehicle relative to the ground. Its function is to provide information on whether the two-wheeled vehicle is turning, tilting, or in a state of potential tipping, which is crucial for determining the timing of unlocking the support 61. The tilt sensor 52 can be a combination of an accelerometer and a gyroscope, which can accurately calculate the pitch and roll angles of the two-wheeled vehicle by measuring the acceleration and angular velocity of the two-wheeled vehicle in different axes; alternatively, it can be an electrolyte tilt sensor, which uses the principle that the change in resistance caused by the change in the liquid level of the electrolyte under the action of gravity to measure the tilt angle.

[0088] For example, in this embodiment, when the two-wheeled vehicle starts, the tilt sensor 52 can detect the tilt angle of the two-wheeled vehicle in real time. When the tilt angle of the two-wheeled vehicle is less than a first threshold (e.g., 8°), the tilt sensor 52 may temporarily not send a sensing signal to the controller 40 to avoid the support part 61 being retracted due to driver misoperation. When the tilt angle of the two-wheeled vehicle is greater than the first threshold, the tilt sensor 52 sends a sensing signal to the controller 40. The controller 40 can control the drive unit 62 to drive the support part 61 from the supported state to the retracted state based on the sensing signal of the tilt sensor 52.

[0089] In some examples, the controller 40 can control the locking member 63 to lock or unlock the support 61 based on the sensing signal of the detection component 50.

[0090] The introduction of the detection component 50 enables the controller 40 to acquire real-time operating status information of the two-wheeled vehicle, such as speed, tilt angle, and whether it is under load, thus providing the controller 40 with accurate decision-making basis. When the two-wheeled vehicle starts or is about to start, the detection component 50 can promptly sense the change in the two-wheeled vehicle's status and transmit the sensing signal to the controller 40. Based on these real-time signals, the controller 40 can quickly determine and issue an unlocking command, ensuring that the support part 61 is unlocked and retracted in time before the two-wheeled vehicle starts moving, avoiding friction noise between the support part 61 and the ground, and significantly reducing the risk of safety accidents caused by the support part 61 not being retracted in time. At the same time, when the two-wheeled vehicle stops, the detection component 50 can also assist the controller 40 in determining whether the two-wheeled vehicle has been stably parked, thereby locking the support part 61 in time to ensure the stability of the two-wheeled vehicle's parking. This not only improves the intelligence level and user experience of the two-wheeled vehicle, but also greatly ensures riding safety.

[0091] In some examples, the two-wheeled vehicle of this embodiment is also equipped with an operation key, which is communicatively connected to the controller 40. The support 61 can be locked or unlocked by manipulating the operation key.

[0092] For example, the operating element can be a button located near the throttle of a two-wheeled vehicle, which locks or unlocks the support 61 by pressing the button. The operating element allows the driver to actively control the support 61 as needed, thereby manually adjusting the support 61 to a retracted or supported state for driving convenience.

[0093] In some examples, please refer to... Figure 3 The two-wheeled vehicle in this embodiment also includes a rear horizontal fork 111 rotatably connected to the frame 10, and the first drive motor 621 and the second drive motor 622 are at least partially located in front of the rear horizontal fork 111.

[0094] Specifically, the rear swingarm 111 is the core load-bearing swing component at the rear of the two-wheeled vehicle, responsible for supporting the rear wheel, guiding the vehicle's movement, coordinating shock absorption and cushioning, and transmitting power and braking force to ensure stable and comfortable driving. By placing at least part of the first drive motor 621 and the second drive motor 622 in front of the rear swingarm 111, the center of gravity of the two-wheeled vehicle can be shifted forward, ensuring more stable handling of the entire vehicle, while also making the overall layout more compact and saving rear space.

[0095] For example, the first drive motor 621 and the second drive motor 622 may be located between two frame main tubes distributed along the width direction of the frame 10.

[0096] In other possible implementations, the first drive motor 621 and the second drive motor 622 may also be located below the rear swingarm 111. In this case, the frame 10 may also include a fixed connecting plate, with the rear swingarm 111 rotatably connected to the fixed connecting plate, and the first drive motor 621 and the second drive motor 622 fixedly connected to the fixed connecting plate.

[0097] In order to solve the problem that the timing of the retraction of the support components in the relevant technology is difficult to control precisely, retraction that is too fast or too slow may cause jamming during the two-wheeled vehicle's operation, and in severe cases, may even lead to safety accidents.

[0098] In some possible implementations, such as Figure 4 and Figure 6 As shown, the support assembly 60 in this embodiment includes at least one support portion 61, a stress sensor 53, and a drive member 62. The stress sensor 53 is disposed on the support portion 61 and is used to detect the intention to retract the support portion 61. For example, the stress sensor 53 can be fixed to the support portion 61 by snap-fit, adhesive, or other methods. The stress sensor 53 is used to communicate with the controller 40 to transmit the detected stress signal to the controller 40. The drive member 62 is also used to communicate with the controller 40. The output end of the drive member 62 is connected to the support portion 61, and the drive member 62 is used to drive the support portion 61 to retract or extend (where retraction is equivalent to the retracted state in the above embodiment, such as...). Figure 9 and Figure 10 As shown; the supported state is equivalent to that in the above embodiments, such as... Figure 7 (As shown). When stress sensor 53 detects stress in the retraction direction in the support 61, it sends a signal to controller 40, which then controls drive member 62 to retract the support 61. Exemplarily, drive member 62 can be a push rod motor, whose push rod 6115 directly pushes or pulls the support 61. Alternatively, drive member 62 can be a rotary motor, driving the support 61 to rotate via gears or linkages.

[0099] Specifically, when stress sensor 53 detects stress in the retracting direction on support 61, it determines that the driver intends to continue driving, and controller 40 is configured to control drive unit 62 to retract support 61. The stress in the retracting direction can be caused by the force resulting from the movement of the two wheels at the moment of starting the vehicle, causing the support to rotate around its contact point with the ground. After receiving the signal from stress sensor 53, controller 40 determines whether the retraction condition has been met based on a preset threshold or algorithm. Once the condition is met, controller 40 sends a command to drive unit 62, which then activates, causing support 61 to transition from a supported state to a retracted state.

[0100] For example, when the driver drives the two-wheeled vehicle forward, the bottom end of the support 61 moves backward relative to the frame 10, and the support 61 generates a backward stress. After the stress sensor 53 detects the stress, it determines that the driver has the intention to drive, and sends a signal to the controller 40. The controller 40 then controls the drive component 62 to drive the support 61 to retract.

[0101] In this embodiment, the support component 60, by installing a stress sensor 53 on the support portion 61 and coordinating with the controller 40 and the drive component 62, achieves accurate judgment and control of the timing of the retraction of the support portion 61. This effectively avoids the two-wheeled vehicle jamming caused by improper retraction timing in related technologies, and the potential safety accidents resulting therefrom, thus significantly improving the safety and smoothness of operation of the two-wheeled vehicle during startup and driving.

[0102] Further, please continue to refer to Figure 6 In this embodiment, the stress sensor 53 is disposed on the support 61 and near the connection between the support 61 and the drive member 62.

[0103] In this embodiment, the stress sensor 53 is directly mounted on the support 61, ensuring that the sensor can directly contact the solid structure of the support 61. The term "close to" refers to the stress sensor 53 being spatially close to the connection area between the support 61 and the drive member 62. This connection point is the main area where the drive member 62 applies force to the support 61, and it is also the part where stress changes are most concentrated and significant during the retraction process. Placing the stress sensor 53 near this area ensures that the sensor can more directly and sensitively capture the stress changes caused by the drive member 62, thereby improving the accuracy and response speed of stress detection and allowing for timely and accurate judgment of the optimal timing for the support 61 to retract. Therefore, the controller 40 can more precisely control the drive member 62 to perform the retraction action, effectively avoiding the jamming phenomenon caused by the support 61 not retracting in time or too early during the two-wheeled vehicle's operation, significantly improving the stability and safety of the two-wheeled vehicle's operation.

[0104] In some examples, the stress sensor 53 can be bonded to the support 61, for example, by adhesive. Specifically, structural adhesives such as epoxy resin or cyanoacrylate adhesive can be used to directly bond the stress sensor 53 to the surface of the support 61 to provide high-strength fixation. Alternatively, elastic adhesives such as silicone sealant or polyurethane adhesive can be used to accommodate minor deformations that may occur in the support 61 under stress, while providing some cushioning.

[0105] Alternatively, the stress sensor 53 can be embedded in the support portion 61, which has a sensor mounting groove. The stress sensor 53 is fixed in the sensor mounting groove with screws. Specifically, a groove or hole matching the shape of the stress sensor 53 can be pre-designed and machined on the support portion 61, and then the stress sensor 53 can be placed in it and fixed by mechanical means such as pressing or snapping. Alternatively, after the sensor is placed in the groove, it can be tightly integrated with the structure of the support portion 61 by filling with resin or performing partial encapsulation.

[0106] This embodiment further ensures the stability of the stress sensor 53's connection to the support 61 by bonding or embedding. This allows the controller 40 to receive more accurate and reliable stress data, thereby enabling it to more precisely determine when the support 61 should retract.

[0107] In some examples, the support 61 is provided with multiple stress sensors 53, which are spaced apart along the circumferential or extending direction of the support 61. By providing multiple such stress sensors 53, the limitation of the limited detection range of a single sensor can be overcome, providing the controller 40 with richer stress data.

[0108] Specifically, the term "circumferential direction" refers to the direction around the axis of the support portion 61, such as on the circumferential surface of the support portion 61. The term "extending direction" refers to the direction along the axis of the support portion 61, such as from one end of the support portion 61 to the other. The distance between two adjacent stress sensors 53 can be set according to specific needs. For example, when the support portion 61 is a rod-shaped structure, multiple stress sensors 53 can be evenly or non-uniformly distributed on the circumferential surface of the support portion 61, for example, at angular intervals of 90 degrees, 120 degrees, or 180 degrees, to cover circumferential stress changes. Alternatively, multiple stress sensors 53 can be arranged along the axis of the support portion 61, for example, from the connection point near the drive member 62 to the direction away from the drive member 62, in an equidistant or unequal manner, to capture stress gradients along the length direction. In some embodiments, the circumferential and extending directions can also be combined, that is, a set of stress sensors 53 can be arranged circumferentially at different length positions of the support portion 61. This interval setting method ensures that the stress sensor 53 can cover the key areas of the support 61, capture stress changes in different directions or positions, and thus obtain a more comprehensive stress distribution map of the support 61 when it is under stress.

[0109] Through the above structure, this embodiment can obtain more comprehensive and detailed stress distribution information of the support 61. The controller 40 performs comprehensive analysis and judgment based on this multi-point stress data, which can significantly improve the perception accuracy of the stress state of the support 61, thereby more accurately identifying the timing when the support 61 generates stress in the retraction direction. This effectively avoids misjudgments caused by blind spots or local stress fluctuations in single sensor detection, ensuring that the drive component 62 retracts the support 61 at the optimal time, thus preventing jamming during the two-wheeled vehicle's operation and significantly improving the stability and safety of the two-wheeled vehicle.

[0110] In some examples, the driving component 62 of this embodiment may include a first driving motor 621, the output end of which is connected to the support portion 61, and the first driving motor 621 is used to drive the support portion 61 to rotate.

[0111] Specifically, in this embodiment, the driving component 62 may only include a first driving motor 621. The first driving motor 621 is used to drive the support part 61 to rotate, thereby realizing the raising or lowering of the support part 61. The first driving motor 621 may be a brushless DC motor, a stepper motor, etc. The output end of the first driving motor 621 is connected to the support part 61, ensuring that the mechanical energy generated by the first driving motor 621 can be effectively transmitted to the support part 61, thereby driving the support part 61 to rotate. For example, the output end of the first driving motor 621 can be connected to the support part 61 through a gear transmission mechanism to convert the rotational motion of the motor into the rotation of the support part 61; or, the output end of the first driving motor 621 can also be connected to the support part 61 through a linkage mechanism or a cam mechanism to achieve complex motion trajectories or specific retracting postures.

[0112] With the above structure, when the stress sensor 53 detects stress in the retraction direction of the support part 61, the controller 40 can accurately control the rotation angle and speed of the first drive motor 621 according to the preset control strategy, so that the support part 61 can complete the retraction action in a smooth and controllable manner, which significantly improves the accuracy and smoothness of the retraction action, effectively solves the problem of jamming or safety hazards caused by retraction that is too fast or too slow, and improves the safety and reliability of the two-wheeled vehicle during driving.

[0113] In some examples, the drive unit 62 of this embodiment includes a third drive motor 623, the output end of which is connected to the support part 61, and the third drive motor 623 is used to drive the support part 61 to extend or shorten.

[0114] Specifically, in this embodiment, the driving component 62 may only include a third driving motor 623. The third driving motor 623 is used to drive the support part 61 to extend or retract, thereby raising or lowering the support part 61 through telescoping. The third driving motor 623 may be a push rod 6115 motor, etc., and its rotation direction is controlled by changing the voltage or current, thereby achieving precise telescoping of the support part 61. For example, when the third driving motor 623 rotates clockwise, it can extend the support part 61; when it rotates counterclockwise, it can retract the support part 61. The output end of the third driving motor 623 is connected to the support part 61 to ensure that the power generated by the third driving motor 623 can be effectively transmitted to the support part 61 to drive it to perform the telescoping or retracting action. For example, the output end of the third driving motor 623 may be connected to the support part 61 through a lead screw and nut mechanism. The rotation of the motor drives the lead screw to rotate, and the nut moves on the lead screw, thereby driving the support part 61 to telescop or retract.

[0115] With the above structure, when the stress sensor 53 detects stress in the retraction direction of the support part 61, the controller 40 can accurately control the rotation angle and speed of the third drive motor 623 according to the preset control strategy, so that the support part 61 can complete the retraction action in a smooth and controllable manner, which significantly improves the accuracy and smoothness of the retraction action, effectively solves the problem of jamming or safety hazards caused by retraction that is too fast or too slow, and improves the safety and reliability of the two-wheeled vehicle during driving.

[0116] In some examples, please refer to Figure 6 In this embodiment, the support portion 61 includes a first portion 6111 and a second portion 6112 connected together. The first portion 6111 can be connected to the frame 10 to achieve overall rotation. The second portion 6112 can be designed as a rod that can extend from inside the first portion 6111, and the two are relatively slidably connected by a sleeve structure or a guide rail structure.

[0117] The driving component 62 may include a first driving motor 621 and a third driving motor 623. The output end of the first driving motor 621 is connected to the first part 6111. The third driving motor 623 is disposed on the first part 6111 and the output end of the third driving motor 623 is connected to the second part 6112. The third driving motor 623 is used to drive the second part 6112 to extend or shorten relative to the first part 6111.

[0118] In this embodiment, the driving component 62 can consist of two independent driving motors. The first driving motor 621 is used to drive the support part 61 to rotate, thereby raising or lowering the support part 61. The third driving motor 623 is used to drive the support part 61 to extend or shorten, thereby raising or lowering the support part 61. Both the first driving motor 621 and the third driving motor 623 can adopt the corresponding structures in the above embodiments, which will not be described again in this embodiment.

[0119] Through the above structure, during the retraction process, the support component 60 of this application can utilize the stress in the retraction direction detected by the stress sensor 53, and the controller 40 coordinates the first drive motor 621 and the third drive motor 623 to perform step-by-step, precise control of the support part 61. Specifically, when the stress sensor 53 detects stress in the retraction direction in the support part 61, the controller 40 can not only control the first drive motor 621 to drive the first part 6111 to rotate as a whole or initially retract, but also simultaneously or independently control the third drive motor 623 to drive the second part 6112 to extend or shorten relative to the first part 6111. This segmented drive and telescopic design means that the support part 61 is no longer a single, unified action during retraction, but can be locally and dynamically adjusted according to the actual stress conditions. For example, when encountering slight resistance or stress changes during retraction, the controller 40 can prioritize instructing the third drive motor 623 to fine-tune the length of the second part 6112 to adapt to the external environment and avoid jamming caused by forced overall retraction. This significantly improves the flexibility and precision of the retraction operation of the support unit 61, effectively avoiding jamming or safety accidents caused by difficulty in controlling the timing of retraction, thereby improving the safety of the two-wheeled vehicle and the user experience.

[0120] Please continue to refer to Figure 7 , Figure 9 and Figure 10 In some possible implementations, the output ends of the first drive motor 621 and the second drive motor 622 are provided with a first gear 6211, and the first part 6111 is provided with a second gear 6118. The first gear 6211 and the second gear 6118 mesh with each other, thereby realizing the transmission connection between the first drive motor 621 and the support part 61.

[0121] In some examples, please refer to Figure 6 The support portion 61 in this embodiment also includes a roller 64, which is disposed at the end of the second portion 6112 away from the first portion 6111.

[0122] Specifically, the roller 64 is a component that can contact the ground by rolling, thereby converting sliding friction into rolling friction. Its main function is to significantly reduce the frictional resistance generated between the support part 61 and the ground during extension or retraction. The roller 64 can be made of wear-resistant rubber, polyurethane, or other elastic materials to provide good cushioning performance and grip, while reducing wear on the ground. The roller 64 can be installed in a fixed-axis manner, allowing it to roll in only one direction; or it can be a swivel caster, allowing it to adapt to multi-directional movement. For example, the roller 64 can be installed at the end of the second part 6112 away from the first part 6111 using mechanical connectors such as pins and bolts, so that its axis is perpendicular or parallel to the extension direction of the second part 6112, thereby achieving smooth rolling.

[0123] In order to address the problems of slow deployment speed, delayed positioning, risk of two-wheeled vehicle tipping, and poor safety of telescopic electric support components in related technologies.

[0124] In some possible implementations, please refer to Figure 4 and Figure 6 The support component 60 in this embodiment includes at least one support portion 61, a drive member 62, and a vehicle speed sensor 51. The drive member 62 is connected to the support portion 61 and is used to drive the support portion 61 to rotate and / or extend or retract. Exemplarily, the drive member 62 can be a push rod 6115 motor, whose push rod 6115 directly pushes or pulls the support portion 61. Alternatively, the drive member 62 can be a rotary motor that drives the support portion 61 to rotate via a gear or linkage mechanism. In some embodiments, the drive member 62 can simultaneously have rotation and extension / retraction functions, achieved by two independent motors respectively. The vehicle speed sensor 51 is used for communication connection with the controller 40, and the drive member 62 is also communication connection with the controller 40. The vehicle speed sensor 51 can be a Hall effect sensor that calculates vehicle speed by detecting the rotational speed of the wheel 30; or a GPS module that acquires vehicle speed information via satellite positioning data. The vehicle speed sensor 51 sends the real-time detected vehicle speed signal to the controller 40 for judgment and decision-making. The controller 40 sends control commands, such as start, stop, acceleration, deceleration, or reverse movement commands, to the drive unit 62 via a communication interface to precisely control the movement of the support unit 61. After receiving the commands, the drive unit 62 executes the corresponding actions and may feed back the execution status to the controller 40.

[0125] The support portion 61 in this embodiment has a retracted position, a pre-supported position, and a supported position. The retracted position falls within the range of the retracted state described in the previous embodiment, specifically corresponding to… Figure 10 The state shown. The pre-support position also falls within the scope of the retracted state in the above embodiments, specifically corresponding to... Figure 9 The state shown. The support position falls within the range of support states described in the above embodiments, specifically corresponding to... Figure 7 The state shown.

[0126] Please continue to refer to Figure 7 , Figure 9 and Figure 10 In this embodiment, when the speed of the two-wheeled vehicle is less than or equal to the first threshold, the controller 40 controls the drive component 62 to drive the support part 61 from... Figure 10 Rotate to the indicated retracted position Figure 9 The pre-support position is shown. For example, when the two-wheeled vehicle begins to decelerate from a high-speed driving state and the speed drops below the first threshold, the controller 40 will immediately issue a command to cause the drive unit 62 to start driving the support part 61 to rotate from the fully retracted position to a pre-support position that is initially deployed.

[0127] When the speed of the two-wheeled vehicle is less than or equal to the second threshold, the controller 40 further controls the drive component 62 to drive the support component 61 from... Figure 9 The pre-support position shown is rotated to Figure 7 The solid line indicates the support position; and the controller 40 controls the drive component 62 to extend the support portion 61. For example, when the two-wheeled vehicle continues to decelerate, and the speed drops below a lower second threshold, the controller 40 will issue another command. At this time, the drive component 62 will continue to drive the support portion 61 to rotate from the pre-support position to the fully extended support position. At the same time, the controller 40 will also control the drive component 62 to extend the support portion 61 to a length sufficient to contact the ground, thereby providing stable support for the two-wheeled vehicle.

[0128] It should be noted that the aforementioned "retracted position" refers to the non-supported position of the support unit 61 when the two-wheeled vehicle is in normal driving condition. In this position, the support unit 61 is usually retracted or folded and does not contact the ground to avoid affecting the movement of the two-wheeled vehicle. The aforementioned "supported position" refers to the fully supported position of the support unit 61 when the two-wheeled vehicle is parked or when stable support is required. In this position, the support unit 61 is usually fully extended and in contact with the ground, effectively supporting the two-wheeled vehicle and preventing it from tipping over. The aforementioned "pre-supported position" refers to an intermediate transition position to which the support unit 61 rotates from the retracted position during the deceleration of the two-wheeled vehicle. In this position, the support unit 61 may not yet be fully extended or in contact with the ground, but it is in a state of readiness to provide support, preparing for subsequent full support.

[0129] Through the above structure, the support component 60 of this embodiment achieves rapid and timely deployment of the support part 61 by controlling the deployment process of the support part 61 in stages, combined with vehicle speed monitoring and dynamic adjustment. Therefore, when the two-wheeled vehicle decelerates or parks, the support part 61 can pre-rotate to enter a pre-support state in advance, and quickly complete full support when the vehicle speed further decreases, thereby effectively reducing the risk of the two-wheeled vehicle tipping over and improving the parking safety of the two-wheeled vehicle.

[0130] In some examples, such as Figure 9 As shown, in this embodiment, when the support part 61 is in the pre-support position, the length of the support part 61 is H1, which is less than the support distance H2. The support distance H2 is the distance between the bottom ground contact point of the support part 61 and the connection point Q between the support part 61 and the frame 10 when the two-wheeled vehicle is in the parked state and the support part 61 is in the support position. The length H1 is set to ensure that when the support part 61 is initially deployed, its end does not prematurely contact the ground, thereby avoiding unnecessary friction, obstruction, or tipping risks while the two-wheeled vehicle still has a certain speed. At the same time, this length is close enough to the ground to prepare for the subsequent fully supported state.

[0131] In some examples, please refer to... Figure 9 When the support part 61 is in the pre-support position, it is located behind the straight line L1. This is to ensure that the support part 61 will not interfere with the driving or steering of the two-wheeled vehicle when initially deployed, and to reserve space for subsequent full support action. For example, the rotation angle of the support part 61 can be precisely controlled by the drive member 62, so that the support part 61 tilts backward by 30 degrees to 60 degrees relative to the straight line L1.

[0132] When the support part 61 is in the supporting position, it is perpendicular to the horizontal plane P1, or it is located in front of the straight line L1. Specifically, these two positions are designed to provide stable and reliable support for the two-wheeled vehicle. When the support part 61 is perpendicular to the horizontal plane P1, it can provide maximum vertical support force, ensuring the balance of the two-wheeled vehicle when stationary. When the support part 61 is located in front of the straight line L1, it can effectively prevent the two-wheeled vehicle from tipping backward when parked.

[0133] This embodiment effectively solves the risk of tipping over caused by improper orientation of the support part 61 by precisely controlling the direction of the support part 61 at different stages of its deployment. This phased and directional control of the deployment of the support part 61 significantly improves the stability and safety of the two-wheeled vehicle when driving at low speeds and parking, and reduces the risk of tipping over.

[0134] Furthermore, when the support part 61 is in the support position, the support part 61 is located in front of the straight line L1; the angle between the straight line L1 and the straight line L2 is greater than or equal to 0° and less than or equal to 10°.

[0135] This embodiment effectively solves the instability problem caused by inaccurate angle of the support component 60 during the deployment process by precisely defining the angle between the support part 61 at the pre-support position and the height direction of the two-wheeled vehicle, thereby significantly improving the reliability and safety of the support component 60.

[0136] In some examples, the first threshold of this embodiment is greater than or equal to 3 km / h and less than or equal to 5 km / h; preferably, the first threshold can be 5 km / h. The second threshold is greater than or equal to 0 km / h and less than or equal to 3 km / h; preferably, the second threshold can be 3 km / h.

[0137] In this embodiment, the first threshold is specifically set to be greater than or equal to 3 km / h and less than or equal to 5 km / h, and the second threshold is specifically set to be greater than or equal to 0 km / h and less than or equal to 3 km / h. This allows the support part 61 to unfold in stages and gradually during the deceleration of the two-wheeled vehicle. For example, when the vehicle speed drops to 5 km / h, the support part 61 begins to rotate from the retracted position to the pre-support position. This initiates support preparation before the two-wheeled vehicle has completely stopped, effectively shortening the time required for the support part 61 to be fully in place. Subsequently, when the vehicle speed further decreases to 3 km / h, the support part 61 rotates from the pre-support position to the support position and extends, ensuring that the support part 61 can be fully in place and provide stable support when the two-wheeled vehicle is about to stop or is at a very low speed. This precise threshold setting optimizes the triggering timing of the support part 61's action, avoiding the problems of slow unfolding speed and delayed positioning of the support part 61 in traditional solutions. It significantly reduces the risk of the two-wheeled vehicle tipping over when parked or traveling at low speeds, thereby improving the parking safety of the two-wheeled vehicle.

[0138] In some examples, please refer to... Figure 6 In this embodiment, the support part 61 includes a first support part 611 and a second support part 612 distributed along the width direction of the two-wheeled vehicle. The first support part 611 and the second support part 612 have the same structure. For example, they can both include a first part 6111 and a second part 6112 connected to each other. The first part 6111 undertakes the main structural support and rotation functions, while the second part 6112 is mainly responsible for the length extension and adjustment.

[0139] The driving component 62 includes a first driving motor 621, a second driving motor 622, a third driving motor 623, and a fourth driving motor 624. The outputs of the first and second driving motors 621 and 622 are connected to the corresponding first portion 6111 for controlling the rotation of the support portion 61. The third and fourth driving motors 623 and 624 are connected to the second portion 6112 for moving the second portion 6112 closer to or further away from the first portion 6111. In this embodiment, the first and second driving motors 621 and 622 are specifically responsible for the rotation of the support portion 61, while the third and fourth driving motors 623 and 624 are specifically responsible for the extension and retraction of the support portion 61, avoiding the complexity of a single driving source needing to coordinate two different types of motion simultaneously.

[0140] This embodiment decouples the rotation and extension actions of the support part 61 by designing the support part 61 as an independently operable first part 6111 and second part 6112, and equipping the rotation and extension functions with a first drive motor 621, a second drive motor 622, a third drive motor 623, and a fourth drive motor 624, respectively. This decoupling design allows the rotation and extension actions to be executed in parallel or in rapid sequence, significantly shortening the overall deployment time of the support part 61 from the retracted position to the pre-supported position and then to the supported position. For example, when the controller 40 determines that the speed of the two-wheeled vehicle is less than or equal to a first threshold based on the vehicle speed sensor 51 signal, the first drive motor 621 or the second drive motor 622 can immediately start driving the first part 6111 to rotate, and simultaneously or immediately afterward, the third drive motor 623 or the fourth drive motor 624 can start driving the second part 6112 to extend, thereby avoiding the delay of switching or coordinating between different actions by a single drive source. This effectively solves the problems of slow deployment speed and delayed positioning of the support part 61 in the prior art, significantly improving the response speed and reliability of the support component 60, thereby reducing the risk of the two-wheeled vehicle tipping over when parked or traveling at low speed, and improving the safety of the two-wheeled vehicle. In addition, this split drive and control also provides a more flexible and efficient means for precise adjustment of the lengths H1 and H2 of the support part 61 at different positions (such as the pre-support position and the support position).

[0141] In some examples, when the support part 61 is in the support position, if the torque of the third drive motor 623 and the fourth drive motor 624 is less than a preset value, the controller 40 controls the third drive motor 623 and / or the fourth drive motor 624 to drive the corresponding second part 6112 to continue to extend relative to the first part 6111.

[0142] In this embodiment, there are multiple ways to detect the torque of the third drive motor 623 and the fourth drive motor 624. For example, the torque can be directly measured by integrating torque sensors on the third drive motor 623 and the fourth drive motor 624; or, the torque can be indirectly estimated by monitoring the operating parameters of the third drive motor 623 and the fourth drive motor 624, such as current, voltage or speed, and combining the performance curves of the motors.

[0143] In this embodiment, when the support part 61 is in the supported position, the controller 40 can monitor the torque of the third drive motor 623 and the fourth drive motor 624 in real time. If the detected torque is less than a preset value, it indicates that the support part 61 is not in sufficient contact with the ground or the support force is insufficient. The controller 40 will respond immediately and control the third drive motor 623 and / or the fourth drive motor 624 to drive the corresponding second part 6112 to continue to extend relative to the first part 6111 until the support part 61 contacts the ground. This adaptive extension mechanism based on torque feedback can effectively compensate for the insufficient support caused by uneven ground or unstable support points, ensuring that the support part 61 is in close contact with the ground, thereby significantly improving the stability of the two-wheeled vehicle in the parked state and avoiding the risk of the two-wheeled vehicle tipping over.

[0144] In some examples, please refer to Figure 11 and Figure 12 In this embodiment, a push rod 6115 and a moving part 6116 may be provided between the first part 6111 and the second part 6112. The output end of the third drive motor 623 or the fourth drive motor 624 is connected to the push rod 6115. The moving part 6116 is fixedly connected to the second part 6112. The third drive motor 623 or the fourth drive motor 624 drives the moving part 6116 to move through the push rod 6115, so as to realize the extension or shortening of the second part 6112 relative to the first part 6111.

[0145] In this embodiment, the third drive motor 623 or the fourth drive motor 624, the push rod 6115, and the moving part 6116 together form a push rod motor mechanism. The extension or shortening of the push rod 6115 can be achieved by controlling the forward and reverse rotation of the third drive motor 623 or the fourth drive motor 624, thereby achieving the extension or shortening of the support part 61.

[0146] In order to solve the problem in related technologies that when a two-wheeled vehicle is parked on an uneven road surface, it may cause the two-wheeled vehicle to tilt to one side or tip over.

[0147] In some possible implementations, please refer to Figure 4 and Figure 6 The support component 60 in this embodiment includes a first support part 611, a second support part 612, and a driving member 62.

[0148] The first support part 611 and the second support part 612 are respectively disposed on the left and right sides of the two-wheeled vehicle. The first support part 611 and the second support part 612 can be designed as a single structure or a telescopic structure. The first support part 611 and the second support part 612 can be hinged to the frame 10 of the two-wheeled vehicle and are arranged symmetrically or asymmetrically on both sides in the width direction of the two-wheeled vehicle in order to provide support when unfolded.

[0149] The driving member 62 is connected to the first support portion 611 and the second support portion 612. The driving member 62 can drive the first support portion 611 and / or the second support portion 612 to rotate, and / or drive the first support portion 611 and / or the second support portion 612 to extend or shorten. The driving member 62 may include one or more motors, which can directly drive the first support portion 611 and / or the second support portion 612 to rotate about their mounting axis, thereby changing the support angle. And / or, the motors can drive the first support portion 611 and / or the second support portion 612 to extend or shorten, thereby changing the support length.

[0150] The detection component 50 is used to communicate with the controller 40, and the drive component 62 is also used to communicate with the controller 40. When the two-wheeled vehicle is parked, the detection component 50 is used to detect the status of the two-wheeled vehicle, and the controller 40 controls the drive component 62 to adjust the rotation angle and / or length of the first support part 611 and / or the second support part 612 based on the detection result of the detection component 50.

[0151] Specifically, the state of the two-wheeled vehicle includes its tilt angle and the distance between the support 61 and the ground. For example, when the two-wheeled vehicle is parked, the detection component 50 can continuously monitor the overall posture of the two-wheeled vehicle to determine whether it is level or whether its tilt angle is greater than a tilt threshold. If the current tilt angle is greater than the tilt threshold, the two-wheeled vehicle is at greater risk of tipping. After receiving a non-level signal, the controller 40 sends a command to the drive component 62 to rotate or extend / retract the first support 611 and / or the second support 612 until the two-wheeled vehicle returns to level. Alternatively, the detection component 50 can detect the contact between the support 61 and the ground, for example, by using a contact sensor to determine whether the support 61 is in complete contact with the ground. If either the first support 611 or the second support 612 is not in complete contact with the ground, the controller 40 will control the drive component 62 to extend or rotate until stable contact is achieved.

[0152] In this embodiment, the support component 60 detects the state of the two-wheeled vehicle and / or the first support part 611 and the second support part 612, and the controller 40 intelligently adjusts the rotation angle and / or length of the first support part 611 and / or the second support part 612, effectively adapting to uneven road surfaces. Therefore, the two-wheeled vehicle remains stable when parked, avoiding tilting or tipping due to differences in road surface elevation, significantly improving parking safety and user experience.

[0153] In some examples, such as Figure 4 As shown, the detection component 50 in this embodiment includes a tilt sensor 52, which is mounted on the frame 10 of the two-wheeled vehicle. For example, the tilt sensor 52 can be fixed to the frame 10 of the two-wheeled vehicle by means of bolts, clips, welding, etc. The tilt sensor 52 is used to collect information on the tilt angle and tilt direction of the two-wheeled vehicle. When the support component 60 is in a supported state and the tilt angle is greater than a preset angle, the controller 40 controls the support part 61 on the same side as the tilt direction to extend until the tilt angle is less than the preset angle.

[0154] For example, when the tilt sensor 52 detects that the two-wheeled vehicle is tilted toward the first support 611 and the tilt angle is greater than a preset angle (e.g., 10°), the controller 40 can drive the first support 611 to rotate or extend through the drive member 62 so that the first support 611 is in stable contact with the ground, thereby adjusting the posture of the two-wheeled vehicle until the tilt angle of the two-wheeled vehicle is less than the preset angle.

[0155] The tilt sensor 52 in this embodiment includes any one of a gyroscope, an accelerometer, and a mercury switch.

[0156] In this embodiment, the detection component 50 is specifically configured to include a tilt sensor 52, which is mounted on the frame 10 of the two-wheeled vehicle. This allows for direct and accurate acquisition of the actual tilt angle of the two-wheeled vehicle in a parked state. The tilt sensor 52 directly measures the tilt state of the frame 10, avoiding measurement errors caused by uneven road surfaces or uncertainties in the contact point between the support part 61 and the ground. This provides the controller 40 with high-precision and high-reliability tilt data. Based on this accurate tilt data, the controller 40 can promptly and accurately determine the tilt direction and degree of the two-wheeled vehicle, and then precisely control the drive component 62 to adjust the rotation angle and / or length of the first support part 611 and / or the second support part 612 to actively compensate for the tilt caused by uneven road surfaces, effectively preventing the two-wheeled vehicle from tipping over.

[0157] In some examples, such as Figure 3 and Figure 4 As shown, the detection component 50 in this embodiment includes a first distance sensor 54 and a second distance sensor 55, and the support part 61 is rotatably connected to the frame 10 through the connection point Q.

[0158] The first distance sensor 54 is used to detect the support distance H2 between the connection point of the first support 611 and the ground;

[0159] The second distance sensor 55 is used to detect the support distance H2 between the connection point of the second support 612 and the ground.

[0160] It should be noted that the support distance H2 between the connection point of the first support part 611 and the ground, and the support distance H2 between the connection point of the second support part 612 and the ground are the same as the support distance H2 in the above embodiment, and can be referred to accordingly. Figure 9 The labels are shown.

[0161] In this embodiment, the first distance sensor 54 is located on the side of the frame 10 facing the ground and close to the first support 611. The second distance sensor 55 is located on the side of the frame 10 facing the ground and close to the second support 612. The purpose of placing the first distance sensor 54 on the side of the frame 10 facing the ground and close to the first support 611 is to directly and accurately measure or predict the support distance of the first support 611. The support distance refers to the distance between the bottom ground contact point of the support 61 and the connection point Q between the support 61 and the frame when the two-wheeled vehicle is parked and in the supported position. This distance dynamically changes depending on the parking location of the two-wheeled vehicle and is a theoretically dynamic real-time value. This arrangement allows the sensor to monitor the local ground conditions under the first support 611 in real time, such as whether there are depressions, bumps, or changes in slope, thereby providing the controller 40 with accurate local distance data for targeted adjustment of the state of the first support 611. Similarly, the second distance sensor 55 is positioned on the side of the frame 10 facing the ground and close to the second support 612, aiming to independently and accurately measure the distance between the ground near the second support 612 and the frame 10. This symmetrical and localized arrangement ensures that the ground conditions on both sides of the two-wheeled vehicle can be independently and accurately perceived, providing the controller 40 with comprehensive ground information, thereby enabling refined control of the overall balance of the two-wheeled vehicle.

[0162] For example, both the first distance sensor 54 and the second distance sensor 55 in this embodiment include a camera or a rangefinder.

[0163] In this embodiment, the support distance between the first support portion 611 and the second support portion 612 on both sides of the two-wheeled vehicle is directly measured by the first distance sensor 54 and the second distance sensor 55. When the two-wheeled vehicle is parked, even if the road surface is uneven, such as one side being lower or higher than the other, the first distance sensor 54 and the second distance sensor 55 can detect the support distance between their respective support portions 61 and the ground. Based on these accurate distance detection results, the controller 40 can accurately determine the actual height difference between the two sides of the two-wheeled vehicle and accordingly finely control the drive component 62 to adjust the rotation angle and / or length of the first support portion 611 and / or the second support portion 612. For example, if the ground on one side of the first support portion 611 is lower, the first distance sensor 54 will detect a larger distance value, and the controller 40 will instruct the drive component 62 to extend the first support portion 611 or adjust its rotation angle to compensate for the height difference, ensuring that the two-wheeled vehicle remains stable and balanced when parked, effectively avoiding the risk of the two-wheeled vehicle tilting or tipping over due to uneven road surfaces.

[0164] In some examples, the first distance sensor 54 of this embodiment includes a first housing, which is mounted to the frame 10 by a first fastener. The second distance sensor 55 includes a second housing, which is mounted to the frame 10 by a second fastener.

[0165] Specifically, the first housing is the external structure used to enclose and protect the first distance sensor 54, and the second housing is the external structure used to enclose and protect the second distance sensor 55. Both the first and second housings can be made of various materials, such as engineering plastics (e.g., ABS, PC), metals (e.g., aluminum alloy, stainless steel), or composite materials. Both the first and second fasteners can be bolts, rivets, self-tapping screws, clips, etc.

[0166] In this embodiment, the first distance sensor 54 is fixed to the frame 10 by the first fastener and the second distance sensor 55 is fixed to the frame 10 by the second fastener. This can prevent the first distance sensor 54 and the second distance sensor 55 from becoming loose, shifting or falling off due to vibration or impact during the operation of the two-wheeled vehicle.

[0167] In some examples, please refer to... Figure 6 Both the first support portion 611 and the second support portion 612 include a first part 6111 and a second part 6112 connected to each other. This structural design allows the first support portion 611 and the second support portion 612 to simultaneously achieve two independent movement modes: rotation and extension. For example, the first part 6111 can serve as the main body of the first support portion 611, responsible for connecting to the frame 10 of the two-wheeled vehicle and achieving overall rotation, while the second part 6112 is responsible for achieving the extension and retraction of the first support portion 611.

[0168] Furthermore, in this embodiment, both the third drive motor 623 and the fourth drive motor 624 are communicatively connected to the controller 40. When the two-wheeled vehicle is parked, the controller 40 is used to extend and / or shorten the corresponding second part 6112 based on the torque value of the third drive motor 623 and / or the torque value of the fourth drive motor 624.

[0169] Through the above structure, the controller 40 of this embodiment can directly use the torque values ​​of the third drive motor 623 and / or the fourth drive motor 624 as feedback to accurately sense the contact force and stress state between the first support 611, the second support 612 and the ground. This torque-based control mechanism allows the controller 40 to respond more sensitively and accurately to changes in the stress on the support 611 when the two-wheeled vehicle is parked, even on uneven surfaces. The controller 40 can finely adjust the extension or shortening of the first support 611 and / or the second support 612 according to the actual stress conditions, ensuring that the support assembly 60 can stably support the two-wheeled vehicle, effectively preventing the two-wheeled vehicle from tilting or tipping over due to uneven surfaces, thereby significantly improving the stability and safety of the two-wheeled vehicle in the parked state.

[0170] To address the issue in related technologies where the driver needs to manually lift the two-wheeled vehicle when starting it.

[0171] In some possible implementations, please refer to Figure 6 , Figure 13 and Figure 14 The support component 60 in this embodiment includes at least one support portion 61, which has a retracted state (e.g., Figure 14 (as shown) and support status (as shown) Figure 13 (As shown).

[0172] like Figure 13 As shown, in this embodiment, the support portion 61 includes a first portion 6111 and a second portion 6112 that are movably connected, and an elastic element 6113 is provided between the first portion 6111 and the second portion 6112. The elastic element 6113 can be a helical spring, with its two ends abutting against the first portion 6111 and the second portion 6112 respectively, allowing relative extension and retraction between the first portion 6111 and the second portion 6112. When subjected to external pressure, the elastic element 6113 is compressed, and the length of the support portion 61 shortens; when the pressure decreases, the elastic element 6113 rebounds, and the length of the support portion 61 extends.

[0173] In this embodiment, the elastic element 6113 includes a first segment and a second segment. The stiffness of the first segment is less than that of the second segment, meaning that the stiffnesses of the two elastic elements 6113 are different; that is, the elastic element 6113 consists of two parts with different stiffnesses. The elastic element 6113 in this embodiment is designed to have nonlinear stiffness characteristics, meaning that its ability to resist deformation is not constant. It exhibits different stiffness values ​​at different compression stages, gradually increasing with the degree of compression, thereby providing progressive support force.

[0174] The length of the support portion 61 in the retracted state is defined as the first length H3 (e.g., ...). Figure 14 As shown), the length of the support portion 61 in the supported state is defined as the second length H4 (as shown). Figure 13 As shown by the solid line, during the process of the support part 61 shortening from the first length H3 to the second length H4, the first segment is compressed. This process indicates that the support part 61 changes from a retracted state to a supported state, allowing the two-wheeled vehicle to be stably supported on the ground. During this process, the elastic element 6113 changes from a free state to a compressed state.

[0175] The length of the support part 61 in its minimum state is defined as the limit length H5 (e.g.) Figure 13 (As shown by the dashed line), the second segment is compressed as the support 61 shortens from the second length H4 to the ultimate length H5. This process represents the two-wheeled vehicle starting forward from a parked position. Figure 13 The solid line position moves to the dashed line position. Since the extreme position length H5 is less than the second length H4, the second segment of the support 61 is compressed, thereby further reducing the length of the support 61. Because the length of the support 61 can be automatically adjusted and reduced, no manual operation by the driver is required.

[0176] As can be seen from the above description, when starting the vehicle in the parked state, this embodiment can automatically adjust the length of the support part 61 based on the pressure and retract the support part 61 without the need for manual operation by the driver, which helps to improve starting efficiency and enhance the driving experience.

[0177] In some examples, the first and second segments of the elastic element 6113 are integrally molded, which helps to reduce the manufacturing difficulty of the elastic element 6113.

[0178] For example, the first segment and the second segment can be connected as one piece by welding.

[0179] In other possible implementations, the elastic element 6113 of this embodiment may also be a composite spring, that is, by connecting or combining two or more elastic elements with different stiffnesses (e.g., helical springs, rubber springs, etc. with different wire diameters or different materials) in series or in parallel, so that they can work sequentially or synergistically under different compression strokes, thereby achieving a gradual change in overall stiffness.

[0180] The elastic element 6113 in this embodiment has at least two stiffnesses, with the stiffness gradually increasing with the amount of compression. This allows the support assembly 60 to provide adaptive support force based on the degree of unevenness of the ground when the two-wheeled vehicle is in contact with the ground while parked. In areas with slight unevenness, the initial stiffness of the elastic element is low, providing a soft cushioning effect that effectively absorbs minor vibrations and prevents the two-wheeled vehicle from swaying due to excessively stiff support. As the degree of unevenness increases, the compression of the elastic element increases, and its stiffness also increases, thereby providing stronger support force and effectively resisting the tilting of the two-wheeled vehicle, preventing tipping. This progressive support characteristic avoids the problems of traditional constant-stiffness elastic elements that provide insufficient anti-tipping effect due to overly soft support in slightly uneven areas, and excessively stiff support that exacerbates the swaying of the two-wheeled vehicle in severely uneven areas.

[0181] In some examples, when the support portion 61 of this embodiment is in a supported state ( Figure 13 (As shown by the solid line in the middle), the force on the elastic element 6113 comes from the weight of the two-wheeled vehicle. At this time, the two-wheeled vehicle is in a parked state, and its own weight can only compress the first section of the elastic element 6113, but cannot compress the second section of the elastic element 6113.

[0182] In some examples, when the support 61 is compressed to its maximum length ( Figure 13 (As shown by the dashed line), the force on the elastic element 6113 comes from the weight of the two-wheeled vehicle and the weight load of the rider and passengers. At this time, the two-wheeled vehicle starts from the parked state, and the weight of the two-wheeled vehicle and the weight load of the rider and passengers can simultaneously compress the first and second sections of the elastic element 6113 to further reduce the length of the support part 61, which can be rotated and retracted.

[0183] In some examples, the first part 6111 and the second part 6112 of this embodiment are nested together, and the elastic member 6113 is disposed within the first part 6111 and the second part 6112, with both ends of the elastic member 6113 abutting against the first part 6111 and the second part 6112 respectively.

[0184] Specifically, the nested arrangement of the first part 6111 and the second part 6112 ensures good guidance and structural stability during relative movement, thereby enabling dynamic adjustment of the length of the first support 611. For example, one implementation could be that the first part 6111 is a hollow tubular structure, and the second part 6112 is a solid rod or a tubular structure with a smaller diameter, allowing the second part 6112 to slide axially within the first part 6111. The elastic element 6113 is housed within the internal space formed by the first part 6111 and the second part 6112, helping it maintain its correct axial position during compression and extension, preventing skewing or jamming, and ensuring the elastic element 6113 functions stably and reliably. For example, the elastic element 6113 could be placed in a cavity formed inside the first part 6111, or in the internal space of the overlapping area formed by the nesting of the first part 6111 and the second part 6112.

[0185] Furthermore, such as Figure 13 As shown, in this embodiment, the second part 6112 is sleeved on the outside of the first part 6111. A first receiving cavity is formed in the first part 6111. A first abutting part 6117 is provided in the first receiving cavity. An elastic member 6113 is located in the first receiving cavity. The two ends of the elastic member 6113 abut against the first abutting part 6117 and the inner wall of the first receiving cavity, respectively. The first abutting part 6117 also abuts against the second part 6112.

[0186] Specifically, the elastic element 6113 can be a helical compression spring, the diameter and length of which match the dimensions of the first receiving cavity, allowing it to be fully contained within it. This arrangement ensures that the elastic element 6113 is guided and protected by the cavity during operation. With this structure, when the elastic element 6113 extends or retracts within the first receiving cavity, it can cause the first abutment portion 6117 to extend or retract as a whole. Since the first abutment portion 6117 abuts against the second portion 6112, the second portion 6112 can be lengthened or shortened relative to the first portion 6111.

[0187] In some examples, such as Figure 13 As shown, a horizontal plane P1 is defined that is perpendicular to the height direction of the two-wheeled vehicle, a straight line L1 is defined that passes through the connection point Q and is perpendicular to the horizontal plane P1, and a straight line L2 is defined that extends along the support part 61.

[0188] When the support part 61 is in the supported state, the support part 61 is located in front of the straight line L1; the included angle β between the straight line L1 and the straight line L2 is greater than or equal to 0 and less than or equal to 10°.

[0189] When the two-wheeled vehicle is parked, by limiting the angle between the first straight line L1 and the second straight line L2 within the above range, it can be ensured that the support part 61 can stably support the two-wheeled vehicle and prevent the two-wheeled vehicle from tipping over.

[0190] In some examples, please refer to... Figure 13 and Figure 14 In this embodiment, the ratio of the first length H3 to the second length H4 is greater than or equal to 1 and less than or equal to 2. Preferably, the ratio of the first length H3 to the second length H4 can be 1.15.

[0191] In some examples, the ratio of the limiting length H5 to the second length H4 is greater than or equal to 0.5 and less than or equal to 1. Preferably, the ratio of the limiting length H5 to the second length H4 can be 0.85.

[0192] In some examples, the two-wheeled vehicle also includes a controller 40 and a drive unit 62, which is connected in drive to the support unit 61 and is also connected in communication with the controller 40. The drive unit 62 can drive the support unit 61 to rotate between a folded state and a supported state under the control of the controller 40.

[0193] For example, the controller 40 can control the drive member 62 to rotate the support part 61 between a folded state and a supported state based on the instructions of the buttons on the two-wheeled vehicle. Alternatively, the controller 40 can control the drive member 62 to rotate the support part 61 between a folded state and a supported state based on the detection results of the detection component 50 in the above embodiments. The specific method by which the controller 40 controls the drive member 62 can be referred to the description in the above embodiments, and will not be repeated in this embodiment.

[0194] In some examples, please refer to... Figure 6 The support portion 61 in this embodiment includes a first support portion 611 and a second support portion 612, which are distributed along the width direction of the two-wheeled vehicle.

[0195] The driving component 62 includes a first driving motor 621 and a second driving motor 622. The output end of the first driving motor 621 is connected to the first support portion 611, and the first driving motor 621 is used to drive the first support portion 611 to rotate. The output end of the second driving motor 622 is connected to the second support portion 612, and the second driving motor 622 is used to drive the second support portion 612 to rotate.

[0196] Specifically, the first drive motor 621 drives the first support portion 611 to rotate, thereby raising or lowering the first support portion 611. The first drive motor 621 can be a brushless DC motor, a stepper motor, or the like. The output end of the first drive motor 621 is connected to the first support portion 611, ensuring that the mechanical energy generated by the first drive motor 621 can be effectively transmitted to the first support portion 611, thereby driving the first support portion 611 to rotate. For example, the output end of the first drive motor 621 can be connected to the first support portion 611 through a gear transmission mechanism, converting the rotational motion of the motor into the rotation of the first support portion 611; or, the output end of the first drive motor 621 can also be connected to the first support portion 611 through a linkage mechanism or a cam mechanism to achieve complex motion trajectories or specific retracting postures. Similarly, the second drive motor 622 can also adopt the above structure, which will not be elaborated further in this embodiment.

[0197] In this embodiment, when the two-wheeled vehicle is parked, the controller 40 can send independent control commands to the first drive motor 621 and the second drive motor 622 according to the unevenness of the road surface. The first drive motor 621 independently drives the first support part 611 to rotate, adjusting the angle and position of the first support part 611; at the same time, the second drive motor 622 independently drives the second support part 612 to rotate, adjusting the angle and position of the second support part 612. This independent control allows the first support part 611 and the second support part 612 to adapt to the height and tilt of their respective contact with the ground, thereby achieving precise adjustment of the overall posture of the two-wheeled vehicle.
