[0069] The e-cargo, especially for carrying goods, is very popular in foreign markets. Such a two-wheeled vehicle is equipped with an electric auxiliary system, usually including a motor, a battery and a control system, which can provide power support for the rider when riding, so that even if a large amount of goods is loaded, the riding is relatively easy. The cargo-carrying two-wheeled vehicle usually has a reinforced frame, a large-capacity cargo rack or an extended cargo platform, which can safely and stably transport goods, such as supermarket shopping, furniture, child pickup or commercial distribution. However, the traditional two-wheeled vehicle has safety hazards and low driving safety.

[0070] At the same time, the traditional cargo-carrying electric-assisted bicycle will be inconvenient to use when driving due to the constantly changing road conditions, such as frequent stopping at traffic lights and safety hazards when stopping to unload goods on the uphill and downhill. The existing improvement method is to add a foot prop on both sides or one side of the cargo-carrying electric-assisted bicycle.

[0071] However, the foot prop in the prior art still has the problem of low convenience of use when frequent stopping is required.

[0072] As shown in FIG. 1, in order to improve the above problems, the present application provides an electric foot prop 3, which comprises a foot prop body 32 and a first driving assembly 31. The foot prop body has opposite first and second ends, and the first end is used to contact the target support. The first driving assembly 31 is drivingly connected to the second end of the foot prop body 32, and the first driving assembly 31 is used to drive the foot prop body 32 to move.

[0073] It can be understood that the foot support body 32 is mounted on the first driving assembly 31, and the foot support body 32 has two ends, one end (the first end) of which contacts the ground during use to support the bicycle. The first driving assembly 31 is connected to the second end of the foot support body 32 and can drive the foot support body 32 to rotate, thereby automatically switching the foot support body 32 between the first position (a retracted position not contacting the ground) and the second position (an extended position contacting the ground to support the bicycle). This means that the user does not need to manually operate the foot support to switch the position from the first position to the second position frequently, thereby improving the convenience of use.

[0074] In an embodiment, as shown in FIG. 1, the electric foot support has a support mode and a recovery mode, and the first driving assembly 31 is used to drive the foot support body 32 to make the electric foot support 3 work in a corresponding one of the support mode and the recovery mode.

[0075] In this way, the two-wheeled vehicle using the electric foot support 3 can lower the electric foot support 3 to enter the support mode when parking is needed, and can retract the electric foot support 3 to enter the recovery mode when parking is not needed.

[0076] In an embodiment, the first driving assembly 31 can be triggered by a key, and a physical key or a touch switch is arranged on the handlebar or the vehicle body. The user can control the first driving assembly 31 to drive the foot support body 32 to make the electric foot support 3 enter the support mode or the recovery mode by pressing the key.

[0077] In an embodiment, the first driving assembly 31 can drive the foot support body 32 according to the vehicle state detected by a gravity sensor or a speed sensor. For example, when the vehicle stops, the speed is reduced to 0, and a foot support extension signal is automatically triggered. The first driving assembly 31 drives the foot support body 32 according to the foot support extension signal to make the electric foot support 3 enter the support mode, and is automatically retracted when starting.

[0078] In an embodiment, the first driving assembly 31 can be driven remotely by integrated Bluetooth or APP, and the user can remotely control the first driving assembly 31.

[0079] In an embodiment, the first driving assembly 31 can be linked with the electric power-assisted system of the vehicle, for example, the foot support is automatically extended when the brake is pinched during parking, and is automatically retracted when the pedal is stepped on.

[0080] It should be noted that the specific form of the first driving assembly 31 to be controlled is not limited here, but depends on the actual application needs.

[0081] In addition, the first driving assembly 31 can use a micro motor, a hydraulic device or a linear drive as a power source, and combine a gear set or a linkage mechanism to transmit power, thereby ensuring smooth and reliable operation.

[0082] It should be noted that the electric kickstand 3 is applied to the cargo bicycle, which is arranged between the front wheel and the rear wheel or arranged at the cargo position to ensure that the vehicle has relatively high balance when parked to avoid rollover.

[0083] For the application of cargo bicycles, compared with some exemplary kickstands, the electric kickstand 3 of the present application adopts electric drive to improve convenience. The specific explanation is as follows: the rider does not need to get off the vehicle to manually deploy or retract the kickstand, especially when carrying heavy cargo. This feature greatly reduces physical burden and improves the efficiency of parking and starting. In complex or emergency parking situations, the electric kickstand 3 can be quickly and automatically deployed to provide stable support immediately, even on slopes, to avoid vehicle sliding and ensure the safety of the cargo. For scenarios where goods are frequently loaded and unloaded, the automatic operation of the electric kickstand 3 greatly reduces the physical labor and operation steps each time the vehicle is parked, which is suitable for long-term and high-intensity commercial distribution or cargo transportation.

[0084] In summary, the electric kickstand can make the cargo bicycle have high convenience in various parking scenarios, and reduce the physical consumption of the rider through quick switching.

[0085] As shown in FIG. 2, the present application provides an auxiliary wheel 100, which includes a bracket 1 having a first fixing position and a second fixing position arranged oppositely, the first fixing position being used to connect a target vehicle body; a wheel body 2 arranged at a position corresponding to the second fixing position of the bracket 1; and a second driving assembly 4 drivingly connected with the bracket 1, the second driving assembly 4 being used to drive the bracket 1 to move the wheel body 2.

[0086] The bracket 1 has a first fixing position and a second fixing position arranged oppositely, the first fixing position being connected to a vehicle body using the auxiliary wheel 100 to ensure that the auxiliary wheel 100 can be firmly mounted on the vehicle body, so that the auxiliary wheel 100 can bear the weight and dynamic load from the vehicle body. The auxiliary wheel 100 is applied to a cargo two-wheeled vehicle, and the loading of goods on the two-wheeled vehicle will cause a significant increase in the weight of the two-wheeled vehicle, and due to the placement position of the goods, an unbalanced moment will be increased. The auxiliary wheel 100 provides a support point to improve the negative effects caused by the increase in weight and the unbalanced moment.

[0087] The auxiliary wheel 100 is installed as an additional support point on the side of the cargo two-wheeled vehicle, and compared with the traditional two-wheeled structure, the structure is more stable. When the vehicle body is loaded with heavy objects, the auxiliary wheel 100 can effectively prevent rollover caused by the shift of the center of gravity, especially in situations such as starting, parking, and turning, which are prone to unstable states, thereby greatly improving the stability and safety of driving.

[0088] Therefore, the auxiliary wheel 100 provided by the application is applied to a cargo double-wheel vehicle. Since the cargo double-wheel vehicle has a large weight, it is difficult to control the balance of the vehicle body when the vehicle is running at a low speed or in a narrow lane, and a safety hazard may be caused. Therefore, the auxiliary wheel 100 is added to the cargo double-wheel vehicle, so that the balance of the vehicle body can be achieved, and the driving safety of the cargo double-wheel vehicle is improved.

[0089] It should be noted that the second driving assembly 4 can be a driving motor or a hydraulic or pneumatic system or an electromagnetic driver, and the like. In the embodiment, the driving motor is adopted. The driving motor can be a one-way motor or a two-way motor. The second driving assembly 4 is used to drive the support 1 to rotate, so that the support 1 drives the wheel body 2 to rotate, and the auxiliary wheel enters the corresponding working mode. The specific implementation is explained in subsequent embodiments. In the embodiment, an auxiliary wheel that can be driven is mainly proposed, and the auxiliary wheel can enter the corresponding working state according to actual needs.

[0090] In an embodiment, as shown in FIG. 3, the auxiliary wheel 100 has an auxiliary mode and a recovery mode. The auxiliary wheel 100 further includes a second driving assembly 4. The second driving assembly 4 is in driving connection with the first fixed position of the support 1. The second driving assembly 4 is used to drive the support 1 to drive the wheel body 2 to move, so that the wheel body 2 works in a corresponding one of the auxiliary mode and the recovery mode.

[0091] It should be noted that the second driving assembly 4 can drive the support 1 with the wheel body 2.

[0092] The second driving assembly 4 is in driving connection with the support 1 connected with the wheel body 2. By driving the support 1, the auxiliary wheel 100 can be moved between two positions. The two positions correspond to the positions of the support 1 or the wheel body 2 in the auxiliary mode and the recovery mode of the auxiliary wheel 100. In the auxiliary mode, the support 1 is close to being perpendicular to the support (the ground), as shown in FIG. 3. The wheel body 2 can contact the support, and the state of assisting the vehicle body to move forward is realized. In the recovery mode, the support 1 is close to being parallel to the support, as shown in FIG. 4. The wheel body 2 is spaced apart from the support by a certain distance, so that the auxiliary wheel 100 does not act.

[0093] The second driving assembly 4 can be a one-way motor or a two-way motor. For the one-way motor, the auxiliary wheel 100 can be driven from the auxiliary mode to the recovery mode, and then the driver moves the auxiliary wheel 100 from the recovery mode to the auxiliary mode by another way. Alternatively, the auxiliary wheel 100 can be driven from the recovery mode to the auxiliary mode, and then the driver moves the auxiliary wheel 100 from the auxiliary mode to the recovery mode by another way. For the two-way motor, the auxiliary wheel 100 can be switched between the auxiliary mode and the recovery mode, so that the full-automatic control is realized, and the use convenience is improved.

[0094] The auxiliary wheel 100 of the double-wheeled vehicle can be switched in position by the system according to the scene, and the second driving assembly 4 is controlled to realize automatic switching, or the user directly controls the second driving assembly 4 to switch. The user actively switches, that is, the user controls the auxiliary wheel 100 to switch the position according to the situation, which has high controllability and adaptability, thereby improving the safety. Or automatic switching, the auxiliary wheel 100 of the double-wheeled vehicle can automatically switch between the recovery state and the auxiliary state according to the driving condition: in the flat, high-speed driving or road condition without additional support, the auxiliary wheel 100 is automatically retracted to the recovery mode, reducing unnecessary ground contact, reducing resistance, and improving riding efficiency; and in the low-speed, starting, heavy-load, turning or facing complex road surface, the auxiliary wheel 100 rapidly drops to the auxiliary mode to support the vehicle body and the main wheel together, thereby significantly enhancing the stability and safety of the vehicle body.

[0095] In the embodiment, the auxiliary wheel 100 also has a support mode, and the second driving assembly 4 is used to drive the bracket 1 to drive the wheel body 2 to move, so that the auxiliary wheel 100 works in a corresponding one of the support mode, the auxiliary mode and the recovery mode.

[0096] The support mode refers to the extension in the auxiliary mode. When the auxiliary wheel 100 is in the auxiliary state, an additional locking mechanism is added to the auxiliary wheel 100, so that the wheel body 2 of the auxiliary wheel 100 cannot rotate. When the wheel body 2 of the auxiliary wheel 100 contacts the ground and cannot rotate, it acts as a foot support, which can make the vehicle body more stable when stationary. For a cargo double-wheeled vehicle, it is particularly important to prevent deflection when parked, which can effectively avoid many safety hazards.

[0097] In an embodiment, the bracket 1 can have an additional support section as a foot support, and the second driving assembly is drivingly connected with the bracket 1 and is used to drive the bracket 1 to rotate. In the support mode, the support section of the bracket 1 is closer to the support (ground), so that the support section can contact the support, thereby supporting the vehicle body; in the auxiliary mode, the wheel body 2 is closer to the support, so that the support section of the bracket 1 does not act, and the wheel body 2 acts, thereby entering the auxiliary mode.

[0098] In an embodiment, the second driving assembly 4 can be triggered by a key. Physical keys or touch switches are arranged on the handlebar or the vehicle body, and the user can control the second driving assembly 4 to drive the auxiliary wheel to enter the auxiliary mode or the support mode or the recovery mode by pressing the keys.

[0099] In an embodiment, the second driving assembly 4 can be driven according to the vehicle state detected by the gravity sensor or the speed sensor, such as when the vehicle speed is reduced to 0 at the time of parking, the support mode starting signal is automatically triggered, and the second driving assembly 4 automatically controls the bracket to rotate to make the auxiliary wheel enter the support mode; in the case of vehicle body starting or deceleration or inclination, the auxiliary wheel can be driven into the auxiliary mode; in the case of high-speed driving, the auxiliary wheel is driven into the recycling mode.

[0100] In an embodiment, the second driving assembly 4 can be driven according to the integrated Bluetooth or APP remote, and the user can remotely control the second driving assembly 4 to drive the auxiliary wheel into the auxiliary mode or the support mode or the recycling mode.

[0101] In an embodiment, the second driving assembly 4 can be linked with the electric power-assisted system of the vehicle, such as the auxiliary wheel automatically enters the auxiliary mode during the process of the vehicle body acting on the electric power-assisted driving.

[0102] It should be noted that the specific form of control of the second driving assembly 4 is not limited here, which depends on the actual application required.

[0103] In an embodiment, as shown in FIG. 5, the auxiliary wheel 100 has a support mode and an auxiliary mode; the auxiliary wheel 100 further comprises: an electric foot prop 3, which is arranged on the bracket 1 and is arranged in a spaced manner with the wheel body 2; a second driving assembly 4, which is drivingly connected with the bracket 1; the second driving assembly 4 is used to drive the bracket 1 to drive the electric foot prop 3 to move, so that the auxiliary wheel 100 works in one of the support mode and the auxiliary mode. Such as, to make the auxiliary wheel 100 change from the support mode to the auxiliary mode; to drive the bracket 1 to drive the electric foot prop 3 to move, so that the auxiliary wheel 100 changes from the auxiliary mode to the support mode.

[0104] It can be understood that the second driving assembly 4 can be only to drive the electric foot prop 3. The electric foot prop 3 is controlled alone, and the work of this second driving assembly 4 is: directly driving the electric foot prop 3 into the support mode or the recycling mode, so that, since the wheel body 2 is always in a state capable of contacting the ground, controlling the electric foot prop 3 can indirectly make the auxiliary wheel 100 enter the auxiliary mode and the support mode. That is, when the electric foot prop 3 is in the support mode, the auxiliary wheel 100 is in the support mode, and when the electric foot prop 3 is in the recycling mode, the auxiliary wheel is in the auxiliary mode.

[0105] First, the electrically powered foot prop 3 can be an additional structure added to the support 1 of the auxiliary wheel 100, and the support 1 can be divided into a first movable part and a second movable part. The wheel body 2 can be arranged in the first movable part and then drivenly connected with the second driving assembly 4 to separately control the position of the wheel body 2. The electrically powered foot prop 3 can be arranged in the second movable part and then drivenly connected with the second driving assembly 4 to separately control the position of the electrically powered foot prop 3.

[0106] Second, the foot prop body of the electrically powered foot prop can be the support 1 itself, that is, the electrically powered foot prop 3 is integrally arranged with the support 1. In this case, the support 1 can have an additional support section as a foot prop to protrude the wheel body 2. The second driving assembly 4 is drivenly connected with the support 1 to drive the support 1 to rotate. In the support mode, the support section of the support 1 is closer to the support (ground), so that the support section can be in contact with the support to support the vehicle body. In the auxiliary mode, the wheel body 2 is closer to the support, so that the support section of the support 1 does not work, and the wheel body 2 works, thereby entering the auxiliary mode.

[0107] It should be noted that the second driving assembly 4 can be a driving motor or a hydraulic or pneumatic system or an electromagnetic driver, etc. The driving motor is adopted in the embodiment, which can be a one-way motor or a two-way motor. For the one-way motor, the auxiliary wheel 100 can be driven from the support mode to the auxiliary mode, and then the driver can move the auxiliary wheel 100 from the auxiliary mode to the support mode by another way. Alternatively, the auxiliary wheel 100 can be driven from the auxiliary mode to the support mode, and then the driver can move the auxiliary wheel 100 from the support mode to the auxiliary mode by another way. For the two-way motor, the auxiliary wheel 100 can be switched between the support mode and the auxiliary mode to realize full-automatic control and improve the use convenience.

[0108] In an embodiment, the second driving assembly 4 can be triggered by a key, and a physical key or a touch switch is arranged on the handlebar or the vehicle body. The user can control the second driving assembly 4 to drive the auxiliary wheel to enter the auxiliary mode or the support mode by pressing the key.

[0109] In an embodiment, the second driving assembly 4 can be driven according to the vehicle state detected by a gravity sensor or a speed sensor. For example, when the vehicle is parked and the speed is reduced to 0, the support mode starting signal is automatically triggered, and the second driving assembly 4 automatically drives the auxiliary wheel to enter the support mode. In the case that the vehicle body is started or decelerated or inclined, the auxiliary wheel can be driven to enter the auxiliary mode.

[0110] In an embodiment, the second driving assembly 4 can be driven according to the integrated Bluetooth or APP remote control. The user can remotely control the second driving assembly 4 to drive the auxiliary wheel to enter the auxiliary mode or the support mode.

[0111] In an embodiment, the second driving assembly 4 can be linked with the electric power-assisted system of the vehicle, for example, to automatically deploy the foot prop when the brake is pinched during parking, so as to make the auxiliary wheel enter the supporting mode.

[0112] It should be noted that the specific form of the second driving assembly 4 to be controlled is not limited here, but depends on the actual application requirements.

[0113] In an embodiment, referring to FIGS. 5-7, the auxiliary wheel 100 further comprises an electric foot prop 3, which is arranged in a spaced manner with the wheel body 2, and the auxiliary wheel 100 has an assisting mode, a supporting mode and a recycling mode; the auxiliary wheel 100 further comprises a second driving assembly 4, which is drivingly connected with the first fixed position of the support 1, and the second driving assembly 4 drives the support 1 to drive the wheel body 2 and the electric foot prop 3 to move, so as to make the auxiliary wheel 100 work in a corresponding one of the assisting mode (as shown in FIG. 5), the supporting mode (as shown in FIG. 6) and the recycling mode (as shown in FIG. 7).

[0114] The second driving assembly 4 can drive the support 1 with the wheel body 2 and the electric foot prop 3, drive the support 1 to drive the wheel body 2 and the electric foot prop 3, change the positions of the wheel body 2 and the electric foot prop 3, or in other words, change the distances between the wheel body 2 and the electric foot prop 3 and the ground, so as to make the auxiliary wheel 100 work in a corresponding one of the assisting mode, the supporting mode and the recycling mode.

[0115] In addition, the electric foot prop 3 is arranged in a spaced manner with the wheel body 2, so as to avoid the electric foot prop 3 from accidentally touching the ground when the wheel body 2 contacts the support.

[0116] In an embodiment, the electric foot prop 3 is directly integrated on the support 1 of the auxiliary wheel 100, is controlled by a driving motor, forms an integral structure, reduces the number of parts, simplifies the installation steps, and at the same time, can also reduce the overall weight, because the separate electric foot prop mounting position and the complex mechanism are no longer needed.

[0117] It should be noted that the second driving assembly 4 can be a driving motor or a hydraulic or pneumatic system or an electromagnetic driver, etc., and the embodiment adopts the driving motor, which can be a one-way motor or a two-way motor.

[0118] In the embodiment, the second driving assembly 4 is specifically used to drive the support 1 to drive the wheel body 2 and the electric foot prop 3 to move, so that the auxiliary wheel 100 works in a corresponding one of the assisting mode and the supporting mode; or, the second driving assembly 4 is specifically used to drive the support 1 to drive the wheel body 2 and the electric foot prop 3 to move, so that the auxiliary wheel 100 works in a corresponding one of the assisting mode and the supporting mode; or, the second driving assembly 4 is specifically used to drive the support 1 to drive the wheel body 2 and the electric foot prop 3 to move, so that the auxiliary wheel 100 works in a corresponding one of the assisting mode and the supporting mode; or, the second driving assembly 4 is specifically used to drive the support 1 to drive the wheel body 2 and the electric foot prop 3 to move, so that the auxiliary wheel 100 works in a corresponding one of the assisting mode, the supporting mode and the recycling mode.

[0119] In an embodiment, the second driving assembly 4 can be a key trigger, and a physical key or a touch switch is arranged on the handlebar or the vehicle body, and the user can control the second driving assembly 4 to drive the auxiliary wheel to enter the assisting mode or the supporting mode or the recycling mode by pressing the key or the touch switch.

[0120] In an embodiment, the second driving assembly 4 can drive the support 1 to drive the wheel body 2 according to the vehicle state detected by a gravity sensor or a speed sensor, for example, when the vehicle is parked and the speed is reduced to 0, the supporting mode starting signal is automatically triggered, and the second driving assembly 4 automatically controls the support to rotate to make the auxiliary wheel enter the supporting mode; in the case that the vehicle body is started or decelerated or inclined, the auxiliary wheel can be driven to enter the assisting mode; in the case of high-speed driving, the auxiliary wheel is driven to enter the recycling mode.

[0121] In an embodiment, the second driving assembly 4 can be driven according to the integrated Bluetooth or APP remote control, and the user can remotely control the second driving assembly 4 to drive the auxiliary wheel to enter the assisting mode or the supporting mode or the recycling mode.

[0122] In an embodiment, the second driving assembly 4 can be linked with the electric power-assisted system of the vehicle, and the auxiliary wheel automatically enters the assisting mode in the process that the vehicle body acts on the electric power-assisted driving.

[0123] It should be noted that the specific control form of the second driving assembly 4 is not limited here, which depends on the actual application requirements.

[0124] It can be understood that the second driving assembly 4 mentioned in the embodiment is used to drive the auxiliary wheel to work in one of the three modes, that is, the auxiliary wheel 100 does not necessarily need the second driving assembly 4 to switch between the three working modes (the auxiliary mode, the support mode and the recovery mode), and can only switch between two working modes, and the second driving assembly 4 drives the auxiliary wheel 100 to switch under the preset working mode matching. In summary, the auxiliary wheel 100 of the embodiment has four control matchings. First, the second driving assembly 4 is used to switch between the auxiliary mode and the support mode, and then the auxiliary wheel 100 is kicked by the foot to switch to the recovery mode. Second, the recovery mode and the auxiliary mode, the second driving assembly 4 is used to switch between the recovery mode and the auxiliary mode, and then the auxiliary wheel 100 is blocked by the foot, and the vehicle body is pushed to switch to the support mode. Third, the second driving assembly 4 is used to switch between the recovery mode and the support mode, and then the auxiliary wheel 100 is blocked by the foot, and the vehicle body is pushed to switch to the auxiliary mode. Fourth, the second driving assembly 4 is used to switch between the recovery mode, the auxiliary mode and the support mode, and full automation control is realized to improve the use efficiency. The rider can be on the vehicle during the driving process, which greatly improves the driving convenience.

[0125] It can also be understood that the second driving assembly 4 can also be used to drive the auxiliary wheel 100 to a certain working mode. For example, the second driving assembly 4 is used to drive the auxiliary wheel 100 to switch to the recovery mode, and then the auxiliary wheel 100 is switched to the auxiliary mode or the support mode by manual operation, and then the second driving assembly 4 switches the auxiliary wheel 100 from the two working modes to the recovery mode. The other working modes are the same, and will not be repeated here.

[0126] It should be noted that the second driving assembly 4 can be a driving motor or a hydraulic or pneumatic system or an electromagnetic driver, etc. The embodiment adopts a driving motor.

[0127] As can be seen, the auxiliary wheel provided by the application has a plurality of driving modes. The driving assembly can be drivingly connected with the bracket with the wheel body, or the driving assembly can be drivingly connected with the electric foot prop, or the driving assembly can be drivingly connected with the bracket with the wheel body and the electric foot prop. At the same time, the number of driving assemblies can be single or multiple. When the number of driving assemblies is single, the driving assembly drives the wheel body or the electric foot prop alone. When the number of driving assemblies is multiple, the driving assemblies can respectively drive the electric foot prop and the wheel body driving connection to drive the wheel body and the electric foot prop alone.

[0128] It needs to be explained that, in the auxiliary wheel 100 works in the auxiliary mode, the wheel body 2 relative to the electric scooter 3, closer to the target support; in the auxiliary wheel 100 works in the support mode, the electric scooter 3 relative to the wheel body 2, closer to the target support; in the auxiliary wheel 100 works in the recycling mode, the wheel body 2 and the electric scooter 3 are away from the target support. The target support generally refers to the ground.

[0129] Referring to Figure 5, in the auxiliary mode of the electric scooter 3 and the wheel body 2, the electric scooter 3 is relatively far away from the support (ground), and the wheel body 2 is relatively close to the support. The wheel body 2 can be in contact with the support, and the wheel body 2 generates action together with the main wheel of the vehicle body to advance and balance the vehicle body. At this time, the electric scooter 3 is slightly lifted to avoid contact with the ground, reduce unnecessary friction loss, and also ensure smooth power output.

[0130] Referring to Figure 6, in the support mode of the electric scooter 3 and the wheel body 2, the wheel body 2 is relatively far away from the support (ground), and the electric scooter 3 is relatively close to the support. The electric scooter 3 can be in contact with the support, and the electric scooter 3 generates action. The main wheel of the vehicle body and the wheel body 2 of the auxiliary wheel 100 do not work, and play a supporting role in the vehicle body and parking.

[0131] Referring to Figure 7, in the recycling mode of the electric scooter 3 and the wheel body 2, the wheel body 2 and the electric scooter 3 are away from the support (ground), and are retracted to the vehicle body, having a certain height difference with the main wheel of the vehicle body. In order to make the vehicle body not work in the process of driving.

[0132] Thus, for the recovery mode: in the case of high-speed driving or good road conditions, the auxiliary wheel 100 can increase unnecessary resistance and instability, affecting the handling and balance of the vehicle body. Therefore, when the auxiliary wheel 100 is not needed to support or assist, the auxiliary wheel 100 can be completely retracted and off the ground, entering the recovery state, reducing the driving resistance and avoiding unnecessary interference during normal riding, ensuring the flexibility and efficiency of the vehicle body under no load or light load conditions, and improving the driving safety. For the auxiliary mode: when the wheel body 2 is grounded and the electrically powered kickstand 3 is off the ground, it can provide additional stability to the vehicle body, especially when turning, passing through wet or uneven road surfaces, or riding at low speed, pushing, or in a narrow area. The auxiliary state helps to share the pressure of the main wheel, increase friction and control force, effectively prevent rollover, and improve stability and safety during driving. For the support mode: when the electrically powered kickstand 3 is grounded, the wheel body 2 can selectively contact the ground, and the electrically powered kickstand 3 acts as a fulcrum, so that the vehicle body is in a locked state, which can prevent the vehicle body from tilting when stationary or moving at low speed, especially when going uphill or downhill, loading or unloading goods, or waiting at traffic lights. It improves the riding safety of the rider, also takes into account the safety of surrounding pedestrians, ensures that the vehicle body can remain in a stable state without the intervention of the rider, and avoids accidents.

[0133] The application also provides a double-wheeled vehicle 200, which comprises a vehicle body 5 and a control assembly arranged on the vehicle body 5; the double-wheeled vehicle 200 further comprises: the electrically powered kickstand 3 according to any one of the preceding embodiments, which is arranged on the vehicle body 5, and the control assembly is connected with the first driving assembly 31 of the electrically powered kickstand 3 and used for controlling the first driving assembly 31 to drive the kickstand body 32 of the electrically powered kickstand 3; and / or the auxiliary wheel 100 according to any one of the preceding embodiments, which is arranged on the vehicle body 5, and the control assembly is connected with the second driving assembly 4 of the auxiliary wheel 100 and used for controlling the second driving assembly 4 to drive the support 1 of the auxiliary wheel 100 to move.

[0134] Since the double-wheeled vehicle 200 comprises the electrically powered kickstand 3 and / or the auxiliary wheel 100, the specific structure of the electrically powered kickstand 3 and the auxiliary wheel 100 is referred to the above embodiments. Since the double-wheeled vehicle 200 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0135] In an embodiment, the double-wheeled vehicle 200 comprises the electrically powered kickstand 3, and the electrically powered kickstand 3 has a support mode and a recovery mode;

[0136] The double-wheeled vehicle 200 further comprises an interactive assembly and / or a sensing assembly arranged on the vehicle body 5, and the interactive assembly and / or the sensing assembly are used for triggering the first control signal;

[0137] The control component is connected with the interaction component and / or the sensing component, and the control component is configured to control the first driving component 31 of the motorized scooter 3 to drive the scooter body 32 of the motorized scooter 3 to work in a corresponding one of the support mode and the recovery mode when the first control signal is received.

[0138] In an embodiment, the interaction component can be a button, can be a touch screen, can be a voice recognition component, etc.

[0139] In an embodiment, the sensing component can be a posture sensor, can be a movement sensor, etc.

[0140] The first control signal can include a first signal and a second signal, the first signal indicating that the auxiliary wheel 100 needs to enter the support mode, and the second signal indicating that the auxiliary wheel 100 needs to enter the assistance mode. The first signal and the second signal can be generated in various ways. For example, a physical button can be provided on the vehicle body 5, and the driving component can be electrically connected to the single or multiple physical buttons to directly control the operation of the driving component. Alternatively, the driving component can be provided with a sound sensor to control the operation of the driving component through voice interaction. Alternatively, a posture sensor can be provided on the vehicle body 5 to automatically generate relevant signals, such as generating the first signal when the vehicle body 5 is stopped and generating the second signal when the vehicle body 5 is started.

[0141] It can be understood that, since the first driving component 31 can be a one-way driving component, the control component can also be one-way controlled, i.e., only receiving the first signal or only receiving the second signal.

[0142] In an embodiment, when the user issues a parking support instruction through the button (interaction component) on the operation interface, or when the sensing component detects that the vehicle speed is reduced to zero and is in a stationary state, the system triggers the first signal. The control component responds to the first signal to start the first driving component 31 through the second driving component to expand the scooter body 32, enter the support mode, and help the vehicle to be stably parked. When the user starts the vehicle again or issues a recovery instruction, the motorized scooter is retracted under the action of the driving component to enter the recovery mode, facilitating the vehicle to continue driving.

[0143] In an embodiment, as shown in FIG. 8, the two-wheeled vehicle 200 is a cargo-carrying two-wheeled vehicle, and the cargo-carrying two-wheeled vehicle further includes a cargo rack 51. The two-wheeled vehicle 200 includes the auxiliary wheel 100, which is arranged at a position of the vehicle body 5 corresponding to the cargo rack 51, or is arranged at a position between the front wheel 52 and the rear wheel 53 of the vehicle body 5.

[0144] It can be understood that the auxiliary wheel 100 is arranged at the position of the vehicle body 5 corresponding to the shelf 51, directly strengthening the support to the area of loading goods, especially when the shelf 51 is full of heavy objects, which can effectively disperse the burden of the vehicle body 5, and prevent the vehicle body 5 from tilting or overturning due to too heavy goods. The auxiliary wheel 100 is arranged at the position between the front wheel 52 and the rear wheel 53 of the vehicle body 5, which is beneficial to balance the whole vehicle body 5, especially when there is no goods or the weight of the goods is unevenly distributed, which can provide an additional middle support point and enhance the lateral stability of the vehicle body 5. When additional balance assistance is needed, such as turning, low-speed driving or starting, stopping, etc., the auxiliary wheel 100 arranged at this position can work more efficiently.

[0145] It should be noted that when the auxiliary wheel 100 is arranged on both sides of the vehicle body 5 of the double-wheeled vehicle 200 between the front wheel 52 and the rear wheel 53 (not including the positions of the front wheel 52 and the rear wheel 53), if the auxiliary wheel 100 has no steering function, it will cause a dragging feeling or resistance when turning, affecting the smoothness of riding, and possibly damaging the parts of the auxiliary wheel 100. Therefore, the present application provides various steering schemes to adapt to various steering needs, ensure high mobility of the vehicle body 5 in a small space, and also ensure that the difference in rotation direction between the wheels will not cause interference or unnecessary wear when the auxiliary wheel 100 turns with the vehicle body 5, thereby significantly improving the use experience and system durability.

[0146] It can be understood that when the auxiliary wheel 100 is installed on the double-wheeled vehicle 200, it needs to follow the double-wheeled vehicle 200 to turn in order to improve the driving stability. Therefore, the present application provides two passive steering schemes and one active steering scheme, which will be described one by one below.

[0147] In an embodiment, when the vehicle body 5 is installed, the auxiliary wheel 100 follows the vehicle body 5 to turn.

[0148] It should be noted that passive steering refers to the structure arranged on the auxiliary wheel 100, which can realize that the wheel body 2 of the auxiliary wheel 100 follows the direction of the vehicle body 5 to turn, the main purpose of which is to ensure that the auxiliary wheel 100 can adapt to the turning action of the vehicle body 5, reduce the resistance and discomfort when turning, and at the same time protect the auxiliary wheel 100 and its related parts from unnecessary stress damage.

[0149] The first passive steering scheme is the omni-directional wheel 6 scheme, as shown in FIGS. 3-9. In this embodiment, the wheel body 2 is an omni-directional wheel 6.

[0150] The omni-wheel 6 is composed of a main wheel and a series of sub-wheels. The main wheel is the central part of the omni-wheel 6, responsible for bearing most of the weight, and connected with the support 1. A plurality of sub-wheels are arranged in a ring around the outer contour of the main wheel, and can rotate independently of the main wheel. The rotation axis of each sub-wheel forms an angle with the rotation axis of the main wheel, usually a perpendicular relationship. Therefore, when the two-wheeled vehicle 200 moves forward, the main wheel of the omni-wheel 6 dominates, and the sub-wheels do not work, so that the auxiliary wheel 100 follows the vehicle body 5 to move forward; when the two-wheeled vehicle 200 turns, the main wheel and the sub-wheels work together, the main wheel rolls towards the moving direction of the vehicle, and the sub-wheels roll towards the turning direction of the vehicle, so as to realize the passive steering function of the auxiliary wheel 100. Thus, the omni-wheel 6 can realize multi-directional movement, equivalent to additional steering function.

[0151] The second passive steering scheme: universal wheel scheme, as shown in FIG. 10, in an embodiment, the auxiliary wheel 100 further comprises a first rotating part 7, the first rotating part 7 is arranged on the support 1, and the support 1 is rotatably connected with the wheel body 2 through the first rotating part 7.

[0152] By adopting the universal joint structure on the support 1 of the auxiliary wheel 100, that is, the first rotating part 7 is arranged on the support 1, the first rotating part 7 allows the rotation power to be transmitted between two components with intersecting axes, while keeping free rotation. When the vehicle body 5 turns, the first rotating part 7 enables the auxiliary wheel 100 to naturally rotate in the direction in which the vehicle body 5 turns, and keeps the same turning angle as the main wheel, thereby reducing friction and resistance.

[0153] Active steering scheme, rudder wheel driving scheme, as shown in FIG. 11, in an embodiment, the auxiliary wheel 100 further comprises a steering driving assembly 8, the steering driving assembly 8 is arranged between the support 1 and the wheel body 2, and the steering driving assembly 8 drives the wheel body 2 to rotate according to the received steering driving instruction.

[0154] The steering driving assembly 8 usually includes a small motor, a sensor (such as an angle sensor), a controller and necessary transmission devices (such as gear, belt or chain transmission system). It is installed between the support 1 and the wheel body 2 of the auxiliary wheel 100, and is directly connected with the wheel body 2, and can accurately control the rotation direction and angle of the wheel body 2 according to the received electronic signal or instruction.

[0155] The steering drive assembly 8 is directly connected with the wheel body 2, and actively controls the driving direction of the wheel body 2 of the auxiliary wheel 100 according to the actual driving direction. When the double-wheeled vehicle 200 starts to turn, the sensor (such as a gyroscope, an accelerometer or a handlebar steering angle sensor) on the vehicle body 5 monitors the steering action and sends the information to the control system. The control system calculates the angle and direction that the auxiliary wheel 100 should turn according to the received real-time steering data, and then sends corresponding steering drive instructions to the steering drive assembly 8. The steering drive assembly 8 responds to the instructions and drives the auxiliary wheel 100 through the motor drive transmission device, so that the wheel body 2 of the auxiliary wheel 100 timely and accurately follows the steering angle of the main wheel and keeps the driving track consistent with the main wheel.

[0156] In addition, the steering drive assembly 8 can also be controlled by a handle. When the handle is turned, the direction of the main wheel of the vehicle body 5 changes, and the wheel body 2 of the auxiliary wheel 100 is also turned, achieving the active steering function.

[0157] It should be noted that for active steering, the degree of turning of the wheel body 2 of the auxiliary wheel 100 is not the same as the degree of turning of the main wheel of the vehicle body 5. Because the auxiliary wheel 100 is arranged between the front wheel 52 and the rear wheel 53, the corresponding degree of turning of the wheel body 2 of the auxiliary wheel 100 needs to be calculated through a trigonometric function according to the distance and position between the wheel body 2 of the auxiliary wheel 100 and the main wheel, when the main wheel turns by one unit angle.

[0158] In an embodiment, as shown in FIG. 8, the double-wheeled vehicle 200 includes the auxiliary wheel 100, and further includes an interactive assembly and / or a sensing assembly arranged on the vehicle body 5, the interactive assembly and / or the sensing assembly being used to trigger a second control signal; a control assembly is connected with the interactive assembly and / or the sensing assembly, and the control assembly is used to control the second drive assembly to drive the bracket 1 to move the wheel body 2 to work in a corresponding mode when the second control signal is received.

[0159] In an embodiment, the interactive assembly can be a key, can be a touch screen, can be a voice recognition assembly, etc.

[0160] In an embodiment, the sensing assembly can be a posture sensor, can be a movement sensor, etc.

[0161] The second control signal can include a first signal, a second signal and a third signal. In an embodiment, the first signal indicates that the auxiliary wheel 100 needs to enter the assisting mode, the second signal indicates that the auxiliary wheel 100 needs to enter the supporting mode, and the third signal indicates that the auxiliary wheel 100 needs to enter the recycling mode. There are various methods for generating the first signal, the second signal and the third signal. For example, a physical button can be arranged on the vehicle body 5, and the physical button is electrically connected to the driving assembly through a single or multiple physical buttons to directly control the operation of the driving assembly. Alternatively, the driving assembly can be provided with a voice sensor, and the driving assembly is controlled to operate through voice interaction. Alternatively, a posture sensor can be arranged on the vehicle body 5 to automatically generate relevant signals. For example, the first signal is generated when the vehicle body 5 is running at a low speed, the second signal is generated when the vehicle body 5 is stopped, the first signal is generated when the vehicle body 5 is started, and the third signal is generated when the vehicle body 5 is running at a high speed.

[0162] In an embodiment, the number of the support 1 and the wheel body 2 is one, and the support 1 and the wheel body 2 are arranged on either side of the vehicle body 5. Alternatively, the number of the support 1 and the wheel body 2 is multiple, and at least one support 1 and at least one wheel body 2 are arranged on both sides of the vehicle body 5.

[0163] The number of the support 1 can be single or multiple. In the present embodiment, two supports 1 are arranged on both sides of the vehicle body 5.

[0164] It should be noted that a single support can not be as effective as a double support in improving the stability of the vehicle body 5 under extreme load or high-speed running, or when turning or avoiding obstacles. Therefore, the present embodiment adopts a double support structure, which can more evenly distribute the load, reduce the bias to the center of the vehicle body 5, and protect the structure of the vehicle body 5 and the auxiliary wheel 100.

[0165] In an embodiment, when the number of the support 1 and the wheel body 2 of the auxiliary wheel 100 is multiple, the driving assembly of the auxiliary wheel 100 is drivingly connected to the multiple supports 1, respectively. Alternatively, the number of the driving assembly corresponds to the number of the support 1, and each driving assembly is drivingly connected to one support 1.

[0166] In this way, one driving assembly can control multiple supports 1, or each driving assembly can control one support 1. The driving assembly of the present embodiment includes the second driving assembly 4, the second driving assembly and the second driving assembly 4 mentioned above.

[0167] When the number of driving assemblies is the same as the number of supports 1, each driving assembly is connected with one support 1, that is, the unfolding and recovering actions of each support 1 are independently controlled, which provides extremely high accuracy and response speed. It is suitable for situations that require fine control or the loads on both sides of the two-wheeled vehicle 200 are uneven. It can ensure that each support 1 operates independently according to actual needs, and optimizes the supporting effect. When the number of driving assemblies is less than the number of supports 1, the driving assemblies can control the movement of multiple supports 1 at the same time, which can reduce the complexity and cost of the driving assemblies, while still ensuring that all supports 1 work together to complete the supporting task.

[0168] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or direct / indirect application in other related technical fields within the technical concept of the present application, using the contents of the present application specification and drawings, are included in the patent protection scope of the present application.
