[0068] Two-wheeled vehicles, especially e-cargo for cargo, are popular in foreign markets. These two-wheeled vehicles are equipped with electric auxiliary systems, usually including motors, batteries and control systems, which can provide power support for riders while riding, making riding relatively easy even when loaded with a large amount of cargo. Cargo two-wheeled vehicles usually have reinforced frames, large-capacity shelves or extended loading platforms, which can safely and stably transport goods, such as supermarket shopping, furniture, child pick-up or commercial delivery.

[0069] In the prior art, in order to improve the adaptability and safety of the cargo two-wheeled vehicle, auxiliary wheels with kickstands are used, so that the kickstands can be lowered when parking is required and can be retracted when assisting the vehicle.

[0070] Traditional training wheels have a bracket with a foot support and a wheel body. Due to the small wheel diameter of the training wheel, when the training wheel is in the auxiliary state or the supporting state, if it encounters a bumpy road, the foot support or the wheel body may accidentally touch the ground, resulting in poor vehicle handling and a safety hazard.

[0071] refer to Figure 1In order to improve the above problems, the telescopic foot support 100 proposed in the utility model includes: a support rod 1, wherein the support rod 1 has a first end and a second end, wherein the first end is used to contact a target support object; a limit member 2, wherein the limit member 2 is disposed at the second end of the support rod 1; a telescopic member 3, wherein the telescopic member 3 is disposed on the support rod 1; the support rod 1 moves to the first position under the cooperation of the limit member 2 and the telescopic member 3; and the support rod 1 moves to the second position under the action of the telescopic member 3.

[0072] In this embodiment, the target support mentioned may be the ground, and the first position mentioned corresponds to the position of the support rod 1 after being extended in the supporting state, referring to Figure 3 The second position mentioned corresponds to the position of the support rod 1 after it is retracted in the recovery state, refer to Figure 4 .

[0073] refer to Figure 3 and Figure 4 The first bracket 4 is rotated around the position close to the second end of the support rod 1. When parking is required, the telescopic foot support 100 is rotated to a state perpendicular to the ground, that is, a supporting state. At this time, under the cooperation of the limit member 2 and the telescopic member 3, the telescopic member 3 is compressed to drive the support rod 1 to extend until it extends to the first position. Figure 3 When the vehicle is moving, the telescopic foot support 100 is turned away from the ground. At this time, the support rod 1 is under the action of the telescopic member 3, and the telescopic member 3 releases the potential energy stored when it was previously compressed, so that the support rod 1 is pulled back a certain distance until the second position, and the support rod 1 is fixed. Figure 4 .

[0074] It should be noted that the stopper 2 is arranged at the second end of the support rod 1, in a relatively fixed position, and the second end of the support rod 1 slides along the periphery of the stopper 2. When the support rod 1 needs to be moved from the retracted state (second position) to the supporting state (first position), the telescopic foot support 100 is turned to a state perpendicular to the ground, and the interaction force between the support rod 1 and the stopper 2 reaches the maximum. The stopper 2 starts to work, forming a thrust to push the support rod 1 from its second end to the first end. At this time, the telescopic member 3 is compressed by the interaction force (thrust) to start working, and may eventually push the support rod 1 to the extended state through the internal spring, air pressure or electric drive mechanism. In contrast, when the support rod 1 needs to be moved from the supporting state (first position) to the retracted state (second position), when the telescopic foot support 100 is turned away from the ground, the interaction force between the support rod 1 and the limiter 2 gradually decreases, and the telescopic member 3 starts to work, possibly through the internal spring, air pressure or electric drive mechanism to pull the support rod 1 back to the second position. It can be seen that the telescopic foot support 100 system realizes the dynamic adjustment of the position of the support rod 1, which not only ensures the stability during parking, but also solves the safety hazard caused by the auxiliary wheel foot support accidentally touching the ground during driving. The instant response capability of the telescopic member 3, combined with the positioning control of the limiter 2, ensures that the support rod 1 can be in the most suitable position under different driving conditions, significantly improving the practicality and safety of the cargo two-wheeled vehicle.

[0075] It is understandable that the extension and contraction mentioned in this embodiment do not refer to the actual change in length of the support rod 1, but the relative movement between the support rod 1 and the limit member 2 or the support rod 1 and the telescopic member 3. Extension means: the external force compresses the spring, and this compression action stores energy, so that the second end of the support rod 1 (the end away from the ground) approaches the first end (the end close to the ground), and finally the end of the support rod 1 touches the ground, completing the support preparation. Contraction means: when support is no longer needed, such as when the vehicle is about to drive, the energy originally stored in the spring is released, and the spring returns to its original length or longer. The tension generated by this recovery process acts on the support rod 1, causing the support rod 1 to slide inward along the original path and return to a position close to the limit member 2 or a fully retracted state. This action reduces the extended length of the support rod 1, making it away from the ground.

[0076] In addition, the support rod 1 can be arranged on a first bracket 4, and the limit member 2 can be arranged on another bracket. By rotating the first bracket 4 where the support rod 1 is located and fixing the other bracket, the support rod 1 can be controlled to move along a required trajectory to control the interaction force between the support rod 1 and the limit member 2.

[0077] In summary, the telescopic foot support 100 proposed by the utility model is applied to auxiliary wheels. Through the cooperation of the telescopic member 3 and the limit member 2, the support rod 1 is extended to contact the ground to realize the parking function, and at the same time, it can prevent the auxiliary wheel from touching the ground. When the auxiliary wheel is in the auxiliary state, the telescopic member 3 is released to shorten the support rod 1, which can prevent the support rod 1 from touching the ground. In this way, the safety of the cargo two-wheeled vehicle using auxiliary wheels with foot supports is improved.

[0078] In this embodiment, the telescopic foot support 100 further includes: a first bracket 4, the first bracket 4 is provided with a through hole, and the support rod 1 passes through the through hole and is movably connected to the first bracket 4. Alternatively, the first bracket 4 does not have a through hole, but the support rod 1 is movably connected to the first bracket 4 through a fixing member 6 with a hole.

[0079] It is understandable that the support rod 1 directly passes through the through hole of the first bracket 4 or is fixed to the first bracket 4 through a fixed member 6 with a hole, and the support member can slide along the through hole to switch between the first position and the second position.

[0080] Through the above two active connection schemes, the controllability of the support rod 1 can be improved, so that the support rod 1 can slide along the direction of the through hole (or the hole of the perforated fixing member 6) to avoid deflection. At the same time, the connection strength between the support member and the first bracket 4 is also strengthened.

[0081] In this embodiment, the telescopic foot support 100 also includes: a driving component 5, which is drivingly connected to the first bracket 4, and the driving component 5 is used to drive the first bracket 4 to move between a third position and a fourth position; wherein, when the first bracket 4 moves to the third position, it drives the support rod 1 to move relative to the limiting member 2, so that the limiting member 2 compresses the telescopic member 3 and fixes the support rod 1 in the first position; when the first bracket 4 moves to the fourth position, it drives the support rod 1 to move away from the limiting member 2 to release the telescopic member 3 and fix the support rod 1 in the second position.

[0082] In addition, the third position and the fourth position correspond to the positions of the first bracket 4 under two different working states (recovery mode and support mode) of the support rod 1. Specifically: the third position refers to the position of the first bracket 4 when the foot support is required. In this position, the first bracket 4, through the action of the driving assembly 5, prompts the support rod 1 with the telescopic part to approach the limiter 2. This action causes the telescopic part 3 to be compressed, so that the support rod 1 is extended to the first position, that is, the ground contact state, providing stable support for the vehicle. The fourth position refers to the position where the first bracket 4 should be located when the foot support is not required, such as when the vehicle is driving. When the first bracket 4 moves to this position, the support rod 1 is away from the limiter 2, and the compressed telescopic part 3 releases energy, pulling the support rod 1 inward to retract to the second position, that is, the recovery state, to ensure that the support rod 1 will not touch the ground, avoiding the safety hazard caused by touching the ground due to bumps during driving.

[0083] It should be noted that the drive component 5 can be a drive motor or a hydraulic or pneumatic system or an electromagnetic drive, etc. The present embodiment adopts a drive motor, which is user-controlled. The user interacts with the drive motor through an interactive method. It should be noted that the drive command is directly transmitted to the first bracket 4 to switch the first bracket 4 between the third position and the fourth position, and drive the support rod 1 to slide between the first position and the second position, thereby improving driving convenience and the adaptability of the two-wheeled vehicle, and can be applied to a variety of environments, thereby improving driving safety.

[0084] The driving assembly 5 in this embodiment is a driving motor, and the driving motor controls the target object to rotate around the connection between the two. The driving assembly 5 is connected to the first bracket 4 close to the second end of the support rod 1 and away from the first end of the support rod 1 to control the first bracket 4 to rotate along this position. After the first bracket 4 is rotated, it will drive the telescopic foot support 100 to rotate together, so as to control the telescopic foot support 100 to rotate to a state perpendicular to the ground, or control the telescopic foot support 100 to rotate away from the ground. Based on this, the telescopic member 3 and the limit member 2 start to work, so that the telescopic foot support 100 is switched between the first position and the second position.

[0085] It is understandable that, through the cooperation of the driving assembly 5 and the first bracket 4, the telescopic foot support 100 is automatically controlled to rotate to a state perpendicular to the ground, or the telescopic foot support 100 is automatically controlled to rotate away from the ground, eliminating the need for manual operation, and realizing the automatic deployment and retraction function of the telescopic foot support 100. This design greatly facilitates the user. When needed, the foot support is automatically extended to the first position to stably support the vehicle, and before driving or when support is not needed, it is automatically retracted to the second position to avoid touching the ground during riding, thereby improving safety and convenience. The use of the drive motor makes the entire process more efficient and faster, reduces the tediousness of human intervention, and can significantly improve user experience and operating efficiency, especially when loading heavy objects or frequently docking.

[0086] It should be noted that the driving assembly 5 can be unidirectional or bidirectional. The unidirectional driving refers to driving the first bracket 4 to move from the first position to the second position, or from the second position to the first position; for driving from the first position to the second position, that is, driving from the support mode to the recovery mode, the driver can use the driving assembly 5 to recover the first bracket 4 and the support rod 1, and kick the first bracket 4 with his feet when support is needed to move it to the first position to achieve support; for driving from the second position to the first position, that is, driving from the recovery mode to the support mode, the driver can use the driving assembly 5 to lower the first bracket 4 or the support rod 1 to support the ground, and kick the first bracket 4 with his feet when support is not needed to move it to the second position to achieve recovery. The driving assembly 5 in this embodiment is a bidirectional driving assembly 5, which can control the first bracket 4 to switch back and forth between the first position (support mode) and the second position (recovery mode) to achieve full process automation control and improve convenience.

[0087] In this embodiment, when the support rod 1 is fixed to the first bracket 4 through the hole-carrying fixing member 6, the number of the hole-carrying fixing member 6 is one; or, the number of the hole-carrying fixing members 6 is multiple, and the multiple fixing members are arranged at intervals.

[0088] It can be understood that the present embodiment adopts two fixing members 6 with holes, which enhance the controllability of the support rod 1, and can make the sliding movement of the support rod 1 more precise, while also increasing the stability of the support rod 1, and can more evenly distribute the weight and stress borne by the support rod 1, thereby enhancing the stability and structural firmness of the entire telescopic foot support 100 system.

[0089] In this embodiment, the telescopic member 3 includes: a first spring 31, which is sleeved on the support rod 1; a sliding block 32, which is fixed to the support rod 1 at a position corresponding to the first spring 31 and the first end of the support rod 1. When the support rod 1 moves, it drives the sliding block 32 to compress the first spring 31 or release the first spring 31.

[0090] After the support rod 1 is arranged between the two fixed members 6 with holes, the first spring 31 is sleeved on the support rod 1, and the sliding block 32 is also fixed on the support rod 1. The first spring 31 and the sliding block 32 move between the two fixed members.

[0091] For switching from the second position to the first position: when the driving assembly 5 drives the first bracket 4 to switch from a state far away from the ground (fourth position) to a state close to the ground (third position), the interaction force between the support rod 1 and the limit member 2 becomes larger, and the support rod 1 slides toward the ground position along the direction of the through holes of the two fixing members. At this time, since the sliding block 32 is fixed on the support rod 1, when the support rod 1 is slid, the sliding block 32 is also driven to slide toward the position of the first spring 31 and compress the first spring 31 to cooperate with the first spring 31 to store energy. When the interaction force reaches the maximum, the elongated length also reaches the preset maximum value and reaches the second position.

[0092] For switching from the first position to the second position: when the driving component 5 drives the support rod 1 to switch from a state close to the ground to a state far away from the ground, the interaction force between the support rod 1 and the limit member 2 becomes smaller, and the support rod 1 is slid toward the position of the driving component 5 along the direction of the through holes of the two fixing members. At this time, since the sliding block 32 is fixed on the support rod 1, when the support rod 1 is slid, the sliding block 32 is also driven to slide toward a position away from the first spring 31, releasing the first spring 31 to cooperate with the first spring 31 to release energy. When the interaction force reaches the minimum, the contracted length also reaches the preset maximum value and reaches the first position.

[0093] There are two forms of the limiter 2:

[0094] First, as Figure 1-Figure 4 As shown, the limiting member 2 is a limiting block 21 , and the limiting block 21 is fixed at a position corresponding to the second end of the support rod 1 .

[0095] The limit block 21 is fixed at a position outside the first bracket 4 to prevent the limit block 21 from being rotated together with the driving assembly 5 connected to the first bracket 4, so that there is no relative movement between the limit block 21 and the support rod 1.

[0096] In this embodiment, a groove is provided on a side of the limiting block 21 facing the support rod 1 , and the groove is used to cooperate with the telescopic member 3 to lock the support rod 1 in the first position.

[0097] It can be understood that the groove can be used as a positioning point or locking mechanism. When the support rod 1 slides to the first position, the specific structure in the groove can interact with the corresponding part on the support rod 1 to form a physical lock, ensuring that the support rod 1 stays firmly in the desired position and will not be easily moved due to external force.

[0098] In addition, when the support rod 1 reaches the first position, the groove can also be used to reduce the noise caused by looseness when the support rod 1 is switched in position, or when in the supporting state, the support rod 1 can be accurately embedded in the groove when it reaches the predetermined position, thereby reducing unnecessary movement and collision, thereby reducing the noise caused by looseness.

[0099] It should be noted that the inside or edge of the groove may be designed with soft materials (such as rubber gaskets) or a shock-absorbing structure, which can absorb the impact energy when the support rod 1 is in place, cushion any minor impacts, and further reduce noise generation.

[0100] Second, if Figure 5-Figure 10 As shown, the limiting member 2 is a limiting link 22, and the limiting link 22 includes: a second bracket 221, the second bracket 221 has a horizontal plate 2211 and two vertical plates 2212 arranged at both ends of the horizontal plate 2211; at least one fixed link 222, the fixed link 222 has a mounting portion, a first fixed portion 2221 and a second fixed portion 2222, the mounting portion is rotatably connected to the vertical plate 2212, one end of the first fixed portion 2221 is used to abut against the telescopic foot support 100, The second fixing portion 2222 is arranged close to the horizontal plate 2211 on a side away from the first fixing portion 2221, so as to cooperate with the horizontal plate 2211 to set the rotation range of the fixing link 222; the second spring 223, the fixing link 222 is provided with a first spring 31 fixing portion 2223, the vertical plate 2212 has a second spring 223 fixing portion 2213, one end of the spring is connected to the first spring 31 fixing portion 2223, and the other end is connected to the second spring 223 fixing portion 2213.

[0101] Similarly, the limiting link 22 is fixed at a position outside the first bracket 4 to prevent the limiting link 22 from being rotated together with the driving assembly 5 connected to the first bracket 4, so that there is no relative movement between the limiting block 21 and the support rod 1.

[0102] It can be understood that the first fixing portion 2221 and the second fixing portion 2222 are an integral body to form a "T"-shaped fixing connecting rod 222. The first fixing portion 2221 of the "T"-shaped fixing connecting rod 222 is the horizontal portion "-", and the left side thereof is connected to the second spring 223. The second fixing portion 2222 is the vertical portion "|", and the bottom thereof abuts against the support rod 1. The bottom of the second fixing portion 2222 is a stepped support surface. It should be further understood that the second fixing portion 2222 is not connected to the center of the first fixing portion 2221, but is connected to the position of the horizontal portion biased towards the second spring 223, and the support rod 1 is located on the side of the fixing connecting rod 222 away from the second spring 223. The above-mentioned stepped support surface has a high-order position and a low-order position. The low-order position is arranged on the side close to the support rod 1. The support rod 1 is located at the low-order position to push the high-order position, so that the fixing connecting rod 222 rotates and pulls the second spring 223.

[0103] In addition, a rotation connection hole 224 is provided on the fixing connecting rod 222, and a same rotation connection hole 224 is also provided on the vertical plate 2212. The two rotation connection holes 224 are correspondingly connected, so that when the fixing connecting rod 222 is pushed by the support rod 1, it rotates around the rotation connection hole 224.

[0104] For the switching from the second position to the first position: when the support rod 1 switches from the state away from the ground to the state close to the ground, the interaction force between the support rod 1 and the limiting member 2 becomes larger. After the limiting member 2 (fixing connecting rod 222) is acted by the acting force, the fixing connecting rod 222 rotates around the rotation connection hole 224, and the rotation direction is towards the position away from the second spring 223 to pull the second spring 223 and store the corresponding potential energy until the support rod 1 is rotated to the third position, that is, from Figures 6 to 8 a conversion process.

[0105] For the switching from the first position to the second position: when the support rod 1 switches from the state close to the ground to the state away from the ground, the interaction force between the support rod 1 and the limiting member 2 becomes smaller. The potential energy stored in the second spring 223 is released, and the fixing connecting rod 222 is pulled back to its original position by the second spring 223, that is, from Figure 8 finally to Figure 6 a conversion process.

[0106] It should be noted that the side of the first fixing portion 2221 facing away from the second fixing portion 2222 is arc-shaped, and a limiting surface 2214 is provided at the corresponding position of the horizontal plate 2211. The two cooperate to set the rotation interval of the fixing connecting rod 222. When the two ends of the first fixing portion 2221 of the fixing connecting rod 222 abut against the limiting surface 2214, the fixing connecting rod 222 cannot rotate in this direction any more and can only rotate in the direction opposite to the original rotation direction again.

[0107] To sum up, among the two forms of the limit members 2, the first structure (limit block 21) is relatively simple and clear, emphasizing simplicity, reliability and low cost, and is suitable for popular products; the second structure (limit link 22) ensures the stability and durability of the entire system, and is suitable for a market with high automation and fine control.

[0108] The auxiliary wheel 200 proposed in the present invention includes a telescopic foot support 100 as described in any one of the above items, wherein the telescopic foot support 100 includes a first bracket 4, wherein the first bracket 4 has a first end and a second end relative to each other, wherein a driving assembly 5 of the telescopic foot support 100 is drivingly connected to the first end of the first bracket 4, wherein the support rod 1, the limiting member 2 and the telescopic member 3 are all arranged at the second end of the first bracket; and a wheel body 7, wherein the wheel body 7 is arranged at the second end of the first bracket 4, and wherein the wheel body 7 is arranged spaced apart from the support rod 1.

[0109] Since the auxiliary wheel 200 includes a telescopic foot support 100, the specific structure of the telescopic foot support 100 refers to the above embodiment. Since the auxiliary wheel 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0110] The wheel body 7, the support rod 1, the limit member 2 and the telescopic member 3 are all arranged on the first bracket 4. When the first bracket 4 is rotated by the driving component 5, the first bracket 4 drives the wheel body 7, the support rod 1, the limit member 2 and the telescopic member 3 to switch between the third position and the fourth position. At the same time, the support rod 1 will also switch between the first position and the second position on the first bracket 4.

[0111] It can be understood that in some exemplary auxiliary wheels, the auxiliary wheels have a wheel body and a kickstand, and can realize an auxiliary mode and a support mode. If the exemplary auxiliary wheels are switched to the auxiliary state on a bumpy road during use, since the length of the kickstand is fixed, the length of the kickstand remains unchanged in the auxiliary mode and the support mode. In order to enable the kickstand to touch the ground in the support mode, the kickstand will extend beyond the wheel body by a certain position. However, since both are fixed to the bracket, the actual positions of both on the bracket will not change, resulting in the possibility that the wheel body may accidentally touch the ground when the auxiliary wheel is in the auxiliary state, which may cause damage to the kickstand and reduce the life of the auxiliary wheel, and also poses a safety hazard.

[0112] Therefore, the auxiliary wheel 200 proposed in this embodiment adopts a telescopic foot support 100, and the telescopic foot support 100 has an adjustable feature, and the length of the telescopic foot support 100 can be adjusted according to actual structural requirements in the auxiliary state and the support mode.

[0113] It is understandable that if Fig.11As shown, when the auxiliary wheel 200 is in the auxiliary state, the wheel body 7 is closer to the ground relative to the supporting end of the telescopic foot support 100. At this time, the telescopic foot support 100 is located on one side of the wheel body 7 and is in a retracted state, that is, when the telescopic foot support 100 is in this position, its length is the preset minimum length. When the telescopic foot support 100 is at the preset minimum length, the telescopic foot support 100 can effectively reduce the situation where the support rod 1 accidentally touches the ground due to uneven road surface when the auxiliary wheel 200 works in the auxiliary mode, thereby increasing the service life of the auxiliary wheel 200 and thereby increasing the safety of use.

[0114] It is understandable that if Fig.12 As shown, when the auxiliary wheel 200 is in the supporting mode, the supporting end of the telescopic foot support 100 is closer to the ground relative to the wheel body 7. At this time, the telescopic foot support 100 is in an extended state, that is, when the telescopic foot support 100 is in this position, its length is the preset maximum length. When the telescopic foot support 100 is at the preset maximum length, the telescopic foot support 100 can effectively reduce the situation where the wheel body 7 accidentally touches the ground due to uneven road surface when the auxiliary wheel 200 works in the supporting mode. If the wheel body 7 accidentally touches the ground when the auxiliary wheel 200 works in the supporting mode on a slope, the vehicle may lose balance and there is a risk of sliding down, which may not only damage the vehicle structure, but also pose a threat to surrounding people and objects.

[0115] The two-wheeled vehicle proposed in the utility model comprises: a vehicle body; the auxiliary wheel 200 as described above, which is arranged on the side of the vehicle body; the number of the auxiliary wheel 200 is one, and the auxiliary wheel 200 is arranged on any side of the vehicle body; or the number of the auxiliary wheels 200 is multiple, and at least one auxiliary wheel 200 is arranged on both sides of the vehicle body.

[0116] Since the two-wheeled vehicle includes auxiliary wheels, the specific structure of the auxiliary wheels refers to the above embodiments. Since the two-wheeled vehicle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0117] The number of the auxiliary wheels 200 can be single or multiple. In this embodiment, two auxiliary wheels 200 are used, and the two auxiliary wheels 200 are respectively arranged on both sides of the vehicle body.

[0118] It should be noted that a single auxiliary wheel may not improve the stability of the vehicle body as significantly as a double auxiliary wheel when under extreme load, especially when turning and making emergency avoidance. Therefore, this embodiment adopts a double auxiliary wheel structure, which can distribute the load more evenly, reduce the bias on the center of the vehicle body, and protect the vehicle body and auxiliary wheel structure.

[0119] In this embodiment, when there are multiple auxiliary wheels, the driving components of the auxiliary wheels are respectively drivingly connected to the first brackets of the multiple auxiliary wheels; or, the number of the driving components corresponds to the number of the first brackets, and each driving component is drivingly connected to one of the first brackets.

[0120] When the number of drive assemblies 5 is the same as the number of auxiliary wheels 200, each drive assembly 5 is specifically connected to one auxiliary wheel 200. This means that the mode switching of each auxiliary wheel 200 is independently controlled, providing extremely high precision and response speed. It is suitable for situations where fine control is required or the load on both sides of the bicycle is uneven, and can ensure that each auxiliary wheel 200 operates independently according to actual needs to optimize the support effect. When the number of drive assemblies 5 is less than the number of auxiliary wheels 200, the drive assembly 5 can control the movement of multiple auxiliary wheels 200 at the same time, thereby reducing the number and cost of drive assemblies 5, while still ensuring that all auxiliary wheels 200 work together to complete the support task.

[0121] In this embodiment, the two-wheeled vehicle also includes a control component, which is electrically connected to the drive component 5 of the auxiliary wheel 200; when the control component receives a first signal, the control component controls the drive component 5 to drive the first bracket 4 of the auxiliary wheel 200 to drive the wheel body 7 and the support rod 1 to move to the third position; when the control component receives a second signal, the control component controls the drive component to drive the first bracket 4 of the auxiliary wheel 200 to drive the wheel body 7 and the support rod 1 to move to the fourth position.

[0122] When the control component receives a specific first signal, it activates the driving component 5, so that the driving component 5 drives the first bracket 4 to rotate along a predetermined path, and finally moves to the third position. Correspondingly, when the control component receives a second signal, the first bracket 4 is similarly adjusted to the fourth position, and the position of the first bracket 4 is switched according to the situation, so that the telescopic foot support 100 can play the maximum role.

[0123] It is understandable that the first signal indicates that the auxiliary wheel 200 needs to enter the support mode, and the second signal indicates that the auxiliary wheel 200 needs to enter the auxiliary mode. There are many ways to generate the first signal and the second signal. It can be a physical button provided on the vehicle body, which is electrically connected to the drive component 5 through a single or multiple physical buttons to directly control the operation of the drive component 5; it can also be a drive component 5 with a sound sensor, which controls the operation of the drive component 5 through voice interaction.

[0124] In this embodiment, the two-wheeled vehicle is a cargo two-wheeled vehicle, and the telescopic leg support 100 is disposed at a position of the vehicle body corresponding to the cargo shelf, or the telescopic leg support 100 is disposed at a position of the vehicle body corresponding to between the front wheel and the rear wheel.

[0125] The auxiliary wheel 200 is arranged at the position of the vehicle body corresponding to the shelf, directly strengthening the support for the cargo loading area, especially when the shelf is full of heavy objects, it can effectively disperse the burden of the vehicle body and prevent the vehicle body from tilting or overturning due to excessive cargo. The auxiliary wheel 200 is arranged at the position between the front wheel and the rear wheel of the vehicle body, which is conducive to balancing the vehicle body as a whole, especially when there is no cargo, or when the weight of the cargo is unevenly distributed, it can provide an additional intermediate support point and enhance the lateral stability of the vehicle. The auxiliary wheel 200 arranged at this position can play an important role when turning, driving at low speed, starting, stopping, etc., when additional balance assistance is required.

[0126] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
