Description

Technical Field

[0001] This application relates to the field of two-wheeled vehicle technology, and more particularly to a linkage-type auxiliary support system that provides auxiliary wheels on both sides of a vehicle to maintain vehicle balance. Background Technology

[0002] Two-wheeled vehicles (hereinafter referred to as motorcycles) have become a widely used means of transportation in people's daily lives due to their lightness and flexibility. However, motorcycles are prone to tilting to the sides when traveling at low speeds, which requires a high level of balance from the driver. When parking, they require human support to maintain balance, especially in rainy or snowy weather or on slippery roads, where it is not only inconvenient for the driver to use their feet to brace themselves, but also poses a safety hazard.

[0003] To address the aforementioned issues, various technical solutions have been proposed in the prior art for installing auxiliary wheels on both sides of two-wheeled motorcycles. For example, patent CN203391898U discloses a balancing system for a two-wheeled motorcycle, which uses a cylinder-driven parallelogram hinge system to extend and retract the auxiliary wheels, providing lateral support at low speeds. Patent CN209208916U discloses an automatic lifting safety auxiliary wheel for two-wheeled electric vehicles and motorcycles, which uses a worm gear motor to drive a wire rope winding, and controls the lifting and lowering of the auxiliary wheels through a lever arm mechanism, automatically recognizing vehicle speed and tilt angle for extension and retraction control.

[0004] However, the aforementioned existing technologies still have the following shortcomings: First, most existing auxiliary wheel systems use independent control of the two support arms. When the road surface is uneven, the support force of one auxiliary wheel changes due to the unevenness of the ground, and the other auxiliary wheel cannot respond in time, which can easily cause an imbalance of the support force on both sides, resulting in the vehicle tilting. Second, the existing system lacks an effective mechanical linkage balancing mechanism, relies too heavily on the response speed and accuracy of the electronic control system, and its reliability needs to be improved under complex road conditions. Third, some solutions can only achieve simple raising and lowering of the auxiliary wheels, and cannot actively apply a reverse balancing torque when the vehicle tilts excessively, thus having limited anti-tipping capabilities; Fourth, in the existing system, the microelectronic controller and sensors need to actively adjust in real time when the road surface changes, resulting in a response delay, and there is a lack of a passive adaptive mechanism that does not rely on electronic control.

[0005] Therefore, a linkage-type auxiliary support system for two-wheeled vehicles is needed. This system should be able to maintain the balance of the driver and the motorcycle from tilting due to uneven road surfaces without active adjustment by a microelectronic controller. When the road surface is uneven and the support force of one auxiliary wheel changes due to the change in ground conditions, the opposite auxiliary wheel should generate a similar change in support force through linkage. This would prevent the driver and the motorcycle from tilting due to uneven road surfaces. At the same time, when the vehicle tilts excessively, the microelectronic controller should be able to actively adjust to maintain the driver's balance. Summary of the Invention

[0006] I. Technical Issues

[0007] The technical problem to be solved by the embodiments of this application is to provide a connected and linked auxiliary support system for two-wheeled vehicles. The system has auxiliary wheels on both sides of the two-wheeled motorcycle, and can perform the following functions under different driving conditions: When the two-wheeled motorcycle is traveling at medium to high speed, the auxiliary wheels on both sides retract. When the vehicle is traveling at low speed, both auxiliary wheels are lowered and on the ground, providing similar support force to the ground on both sides. When the support force on one side of the auxiliary wheel changes due to uneven ground, the support force on the other auxiliary wheel changes accordingly through the linkage of the two-sided brackets and the adjustable connecting components between them, so that the original balance of the two-wheeled motorcycle can be maintained. When the vehicle is traveling at low speed or parked, the microelectronic controller senses that the vehicle is tilted excessively to one side through sensors. Under the combined action of the balance control component, the two side brackets and the adjustable connection components between them, the ground support force of the auxiliary wheel on the tilted side increases and the ground support force of the auxiliary wheel on the other side decreases, thereby generating a reverse balancing torque to keep the two-wheeled motorcycle balanced.

[0008] II. Technical Solution

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] 1. Overall Composition

[0011] A linkage-type auxiliary support system for a two-wheeled vehicle includes: a base, a left support assembly, a left auxiliary wheel, a right support assembly, a right auxiliary wheel, an adjustable connection assembly, and one or more balance control assemblies; it also includes a microelectronic controller, which contains sensors and control circuits for sensing the driving status of the two-wheeled motorcycle and the position, pressure or stress information of each component.

[0012] 2. Base

[0013] The base is used to connect to or be integrally formed with the frame of a two-wheeled vehicle. The base includes a base body, and fixed to the base body are: a left base-support connector and a right base-support connector, which are respectively hinged to the left support assembly and the right support assembly; and at least one base-adjustment connector, which is directly or indirectly connected to the balance adjustment assembly.

[0014] 3. Left and right support components and auxiliary wheels

[0015] The supporting end of the left support assembly and the left auxiliary wheel are located on the left side of the motorcycle, and the supporting end of the right support assembly and the right auxiliary wheel are located on the right side of the motorcycle. Both the left and right auxiliary wheels are circular wheel assemblies.

[0016] The left support assembly is hinged to the base and the left auxiliary wheel, and connected to the adjustable connection assembly and the balance control assembly. Specifically, the left support assembly is a motion connection assembly composed of a main structural member or multiple members, and is respectively provided with a support-base connector, a support-auxiliary wheel connector, and a support-balance connection connector. The support-base connector of the left support assembly is hinged to the left base-support connector of the base, allowing the left support assembly to swing around the hinge axis, the direction of which is the same as or at an acute angle to the front-rear direction of the motorcycle. The left auxiliary wheel is hinged to the support-auxiliary wheel connector of the left support assembly, allowing the left auxiliary wheel to rotate around its own axis; when the auxiliary wheel is on the ground, the direction of its axis is the same as or at an acute angle to the left-right direction of the motorcycle.

[0017] The right support assembly is hinged to the base and the right auxiliary wheel, and connected to the adjustable connection assembly and the balance control assembly. Its right side structure is similar to the left side; that is, the right support assembly is a motion connection assembly composed of main structural members or multiple members, and it is equipped with a support-base connector, a support-auxiliary wheel connector, and a support-balance connection connector. The support-base connector of the right support assembly is hinged to the right base-support connector of the base, allowing the right support assembly to swing around a hinge axis. The direction of this axis is the same as or forms an acute angle with the front-rear direction of the motorcycle. The right auxiliary wheel is hinged to the support-auxiliary wheel connector of the right support assembly, allowing the right auxiliary wheel to rotate around its own axis. When the auxiliary wheel is on the ground, the direction of this axis is the same as or forms an acute angle with the left-right direction of the motorcycle.

[0018] 4. Balance control components

[0019] The balance control component is an actuator used to control the supporting torque of the left and right support components, and includes one or more balance control components. When there is one balance control component, it is connected between the base and the left support component or the right support component. When there are multiple balance control components, at least one balance control component is connected between the base and the left support component, and at least one balance control component is connected between the base and the right support component. Specifically, the balance control component includes at least one control body and one control member. The control body and control member of the balance control component are respectively provided with control-external connectors. One of the control-external connectors of the balance control component is directly or indirectly connected to a corresponding base-control connector on the base to position the balance control component on the base and allow a defined relative motion relationship between them. The other control-external connector of the balance control component is directly or indirectly connected to the left support component and / or the right support component.

[0020] The control component and the control body form a kinematic connection, allowing them to generate relative displacement, thus constituting a set of kinematic pairs for adjusting the support balance. The microelectronic controller adjusts the relative distance between the two control-external connectors of the balance control component, thereby adjusting the swing of the left support component and / or the right support component around the axis of its hinge to the base. By adjusting the movement of the left and right support components through the balance control component, the supporting force of the auxiliary wheels on both sides is adjusted.

[0021] The balance control component has the following operating modes: (1) Locking mode: The length or angle of the balance control component remains locked and fixed; (2) Passive following mode: The balance control component can freely extend, retract or swing under the action of external force, so as to allow the auxiliary wheel to float with the undulation of the ground; (3) Active control mode: Under the control of external commands or sensor signals, the balance control component actively outputs driving force to adjust its length or angle.

[0022] As a specific implementation, the balance control component can be implemented using a linear drive unit or an angle drive unit. The linear drive unit refers to an actuator that can convert hydraulic energy, pneumatic energy, or electrical energy into linear motion to achieve linear telescopic displacement; the angle drive unit refers to an actuator that can convert hydraulic energy, pneumatic energy, or electrical energy into angular position adjustment to achieve rotational or oscillating angular displacement.

[0023] 5. Adjustable connection component

[0024] The adjustable coupling assembly is connected between the left support assembly and the right support assembly to enable them to move together. The adjustable coupling assembly is a linear drive unit or an angle drive unit, with its two ends connected to the left support assembly and the right support assembly, respectively.

[0025] The adjustable connection assembly includes at least a connection body and a connection member. The connection body and the connection member of the adjustable connection assembly are respectively provided with external connection parts that connect to the left and right support assemblies.

[0026] The adjustable connection component is configured such that when the ground support force of one auxiliary wheel changes due to ground undulations, the mechanical linkage between the adjustable connection component and the left support component and the right support component causes a corresponding change in the ground support force of the other auxiliary wheel, thereby reducing the difference in ground support force between the two auxiliary wheels.

[0027] By connecting and linking with the left and right support components, the adjustable connection component can adjust the raising, lowering and ground support of the auxiliary wheels on both sides by changing the distance between the connection-external connectors on both sides.

[0028] The connecting component and the connecting body form a kinematic connection, and the two can generate controllable forces and relative displacements under the action of driving force, thereby forming a set of kinematic pairs for adjusting the supporting force and position. The relative displacement between the connecting component and the connecting body can drive the relative displacement between the connecting-external connector of the adjustable connecting assembly. The microelectronic controller provides a power source to drive the adjustable connecting assembly according to a preset program or external instructions, thereby realizing the control of the forces and relative positions generated between the connecting component and the connecting body.

[0029] 6. Microelectronic Controller

[0030] The system also includes a microelectronic controller. The microelectronic controller contains sensors and control circuitry for sensing the motorcycle's driving status and the position, pressure, or stress information of its components. The microelectronic controller is configured such that when it senses a tilt of the vehicle to one side exceeding a preset threshold (a comprehensive measure of current driving conditions including speed, handlebar angle, load, etc.), the drive balance adjustment component shortens or lengthens the relative distance between its two ends, increasing the ground support force of the auxiliary wheel on that side. Simultaneously, through the transmission of the adjustable coupling component, the ground support force of the auxiliary wheel on the other side decreases, thereby generating a reverse balancing torque.

[0031] 7. Working Principle

[0032] The microelectronic controller senses the driving status of the two-wheeled motorcycle through sensors, and executes the following controls based on the sensing results and / or external commands:

[0033] Medium-high speed driving mode: When the two-wheeled motorcycle is traveling at medium-high speed, the adjustable coupling component is driven to change the relative distance between the coupling-external connecting parts at both ends (shorten or lengthen), so that the distance between the support-balance coupling connecting part of the left support component and the support-balance coupling connecting part of the right support component changes, thereby driving the left and right auxiliary wheels to retract.

[0034] Low-speed stable driving mode: When the motorcycle is traveling at low speed, the adjustable coupling assembly is driven, causing the relative distance between the coupling-external connecting parts at both ends to change in the opposite direction (lengthening or shortening) to the "medium-high speed driving mode". This changes the distance between the support-balance connecting parts of the left support assembly and the right support assembly, thereby causing the left and right auxiliary wheels to lower and support the ground. When the motorcycle is traveling at low speed, if the support force of one auxiliary wheel changes due to uneven ground, without active intervention from the controller, the support force of the other auxiliary wheel also changes accordingly through the linkage of the adjustable coupling assembly, the left support assembly, and the right support assembly, reducing the difference in the ground support force between the two auxiliary wheels and maintaining the original balance of the motorcycle.

[0035] Anti-tipping active intervention mode: When the two-wheeled motorcycle is traveling at low speed or parked, the left and right auxiliary wheels are controlled to lower and support the ground. When the microelectronic controller senses that the vehicle tilts to one side beyond the preset threshold of the current riding state, it drives the corresponding balance control component. Through the action of the left and right support components and the adjustable connection component, the ground support force of the tilted auxiliary wheel is increased and the ground support force of the other auxiliary wheel is decreased, thereby generating a reverse balance torque to keep the two-wheeled motorcycle balanced.

[0036] 8. Technical Effects

[0037] By creatively setting the adjustable connecting component between the left support component and the right support component, the left support component and the right support component can be linked together; by adopting the above technical solution, the present invention has the following beneficial effects: (1) By controlling the distance between the connecting-external connectors on both sides of the adjustable connecting component, the auxiliary wheel can be smoothly retracted and lowered to support the ground. (2) Through the linkage between the adjustable connection component and the support components on both sides, when the road surface is uneven, the change in the support force of the auxiliary wheel on one side can be transmitted to the other side through the mechanical balance mechanism to reduce the difference in the support force of the auxiliary wheels on both sides to the ground. Without the active control of the microelectronic controller, the vehicle tilt can also be effectively suppressed. (3) By setting up a balance control component, when the vehicle is tilted excessively, the balance control component can be driven to apply a reverse balance torque under the active control of the microelectronic controller, thereby further improving the anti-tipping ability; (4) The overall structure is simple and highly reliable, reducing the dependence on electronic control systems and making it more adaptable to complex road conditions.

Example 1

[0050] Figures 1 to 3 This is a preferred embodiment of the present application.

[0051] In this embodiment, a base 1, a left support component 21, a left auxiliary wheel 22, a right support component 23, a right auxiliary wheel 24, an adjustable connecting component 4, and two balance control components 3 are provided. The left support component 21 and the right support component 23 are located on both sides of the base, and the two balance control components 3 and the adjustable connecting component 4 are located below the base 1.

[0052] The base 1 is used to connect to the frame of a two-wheeled motorcycle. The base 1 includes the base body 11, and the left base-support connector 12, the right base-support connector 13, the left base-adjustment connector 14, and the right base-adjustment connector 15, which are fixedly disposed on the base body 11.

[0053] The left support assembly 21 and the left auxiliary wheel 22 are located on the left side of the motorcycle, and the right support assembly 23 and the right auxiliary wheel 24 are located on the right side of the motorcycle. The left auxiliary wheel 22 and the right auxiliary wheel 24 are circular wheel assemblies.

[0054] The left support assembly 21 is hinged to the base 1 and the left auxiliary wheel 22, and connected to the adjustable connection assembly 4 and the balance control assembly 3. Specifically, the left support assembly 21 is a parallelogram-like motion connection assembly composed of multiple rod components, on which a support-base connector 25, a support-auxiliary wheel connector 26, and a support-balance connection connector 27 are respectively provided. The support-base connector 25 of the left support assembly 21 is hinged to the left base-support connector 12 of the base 1, allowing the left support assembly 21 to swing around the hinge axis, the direction of which is approximately the same as the front-rear direction of the motorcycle. The left auxiliary wheel 22 is hinged to the support-auxiliary wheel connector 26 of the left support assembly 21, allowing the left auxiliary wheel 22 to rotate around its own axis; when the auxiliary wheel is on the ground, the direction of its axis is approximately the same as the left-right direction of the motorcycle.

[0055] The right support assembly 23 is hinged to the base 1 and the right auxiliary wheel 24, and connected to the adjustable connection assembly 4 and the balance control assembly 3. Similarly, the right support assembly 23 is a parallelogram-like motion connection assembly composed of multiple rod components, on which a support-base connector 25, a support-auxiliary wheel connector 26, and a support-balance connection connector 27 are respectively provided. The support-base connector 25 of the right support assembly 23 is hinged to the right base-support connector 13 of the base 1, allowing the right support assembly 23 to swing around the hinge axis, the direction of which is approximately the same as the front-rear direction of the motorcycle. The right auxiliary wheel 24 is hinged to the support-auxiliary wheel connector 26 of the right support assembly 23, allowing the right auxiliary wheel 24 to rotate around its own axis; when the auxiliary wheel is on the ground, the direction of its axis is approximately the same as the left-right direction of the motorcycle.

[0056] One side of a balance control component 3 has an external control connector 37 hinged to a left base-control connector 14 on the base 1, positioning the balance control component 3 on the base 1 and allowing the control body 32 to swing about the hinge axis. The other side of the balance control component 3 has an external control connector 37 indirectly connected to the left support component 21 via an auxiliary link 28. The other side of a balance control component 3 has an external control connector 37 hinged to a right base-control connector 15 on the base 1, positioning the balance control component 3 on the base 1 and allowing the control body 32 to swing about the hinge axis. The other side of the balance control component 3 has an external control connector 37 indirectly connected to the right support component 23 via an auxiliary link 28.

[0057] The balance control component 3 includes a control body 32 and a control member 33. The control member 33 and the control body 32 are kinematically connected, allowing them to generate relative displacement, thus forming a set of kinematic pairs for adjusting and supporting balance. The balance control component 3 employs a linear drive unit, which has locking mode, passive mode, and active mode.

[0058] The adjustable connection component 4 is a linear drive unit, with its two ends connected to the left support component 21 and the right support component 23, respectively. Specifically, the adjustable connection component 4 includes a connection body 41 and a connection member 42. Both the connection body 41 and the connection member 42 of the adjustable connection component 4 are provided with external connection parts 43, which are connected to the left support component 21 and the right support component 23 respectively via auxiliary connecting rods 28. When the ground support force of one auxiliary wheel changes due to ground undulations, the mechanical linkage between the adjustable connection component 4 and the left and right support components 21 and 23 causes a corresponding change in the ground support force of the other auxiliary wheel, thereby reducing the difference in ground support force between the two auxiliary wheels.

[0059] The adjustable connection component 4 changes the distance between the two side connection-external connectors 43 and is linked with the left and right support components 21 and 23: when the distance between the two side connection-external connectors 43 is extended, the auxiliary wheels on both sides rise (e.g., Figure 3 (As shown in the diagram); when the distance between the two side connections and the external connector 43 is shortened, the two side auxiliary wheels are lowered (as shown in the diagram). Figure 1 , Figure 2 (The state shown).

[0060] The system also includes a microelectronic controller. The microelectronic controller senses the driving status of the motorcycle through sensors and executes the following controls based on the sensing results and / or external commands:

[0061] Medium-high speed driving mode: When the two-wheeled motorcycle is traveling at medium-high speed, the adjustable coupling component 4 is driven, which increases the relative distance between the coupling-external connecting parts 43 at both ends, thus increasing the distance between the support-balance coupling part 27 of the left support component 21 and the support-balance coupling part 27 of the right support component 23, thereby causing the left auxiliary wheel 22 and the right auxiliary wheel 24 to retract (e.g., Figure 3 (The state shown).

[0062] Low-speed stable driving mode: When the two-wheeled motorcycle is traveling at low speed, the adjustable coupling assembly 4 is driven, which shortens the relative distance between the coupling-external connectors 43 at both ends, and shortens the distance between the support-balance coupling connector 27 of the left support assembly 21 and the support-balance coupling connector 27 of the right support assembly 23, thereby causing the left auxiliary wheel 22 and the right auxiliary wheel 24 to lower their ground support (e.g., Figure 1 , Figure 2 (As shown in the diagram). When the two-wheeled motorcycle is traveling at low speed, when the support force of one auxiliary wheel changes due to uneven ground, the support force of the other auxiliary wheel also changes accordingly through the linkage of the adjustable connecting component 4 and the left support component 21 and right support component 23, so as to reduce the difference in the support force of the two auxiliary wheels on the ground and maintain the original balance of the two-wheeled motorcycle.

[0063] Anti-tipping active intervention mode: When the two-wheeled motorcycle is traveling at low speed or parked, the left and right auxiliary wheels 22 and 24 are controlled to lower their ground support; when the microelectronic controller senses that the vehicle tilts to one side and exceeds the preset threshold of the current driving state, the control component of the balance control component on the tilted side is driven to generate traction force towards the control body and / or the control component of the balance control component on the opposite side is driven to generate support force towards the opposite side of the control body. Through the action of the left and right support components and the adjustable connecting component 4, the ground support force of the auxiliary wheel on the tilted side is increased and the ground support force of the auxiliary wheel on the opposite side is decreased, thereby generating a reverse balance torque to keep the two-wheeled motorcycle balanced.

[0064]

Example 2

[0065] Figure 4 and Figure 5 Another embodiment of this application is shown.

[0066] This embodiment and Figure 1 The embodiments are largely similar, with the main difference being that the two balance adjustment components 3 and the adjustable connection component 4 are positioned above the base; and the support-balance connection connector 27 of the left support component 21 and the right support component 23 is positioned differently from... Figure 1 The embodiments differ in that when the distance between the connecting-external connectors 43 on both sides of the adjustable connecting component 4 is shortened, the auxiliary wheels on both sides are raised; when the distance between the connecting-external connectors 43 on both sides is extended, the auxiliary wheels on both sides are lowered.

[0067] The adjustable connection component 4 also employs a linear drive unit.

[0068] Other connection relationships in this embodiment are Figure 1 The embodiments are similar and will not be repeated here.

[0069]

Example 3

[0070] Figure 6 and Figure 7 Another embodiment of this application is shown.

[0071] In this embodiment, the system includes a base 1, a left support assembly 21, a left auxiliary wheel 22, a right support assembly 23, a right auxiliary wheel 24, an adjustable connecting assembly 4, and two balance control assemblies 3. The left support assembly 21, the right support assembly 23, the two balance control assemblies 3, and the adjustable connecting assembly 4 are disposed below the base 1.

[0072] The base 1 includes a base body 11, and a left base-support connector 12, a right base-support connector 13, a left base-adjustment connector 14, and a right base-adjustment connector 15, all fixedly mounted on the base body 11. The base body 11 is integrally formed with the vehicle frame. The left base-support connector 12 is located on the right side of the base 1, and the right base-support connector 13 is located on the left side of the base 1.

[0073] The left auxiliary wheel 22 is located on the left side of the two-wheeled motorcycle, and the right auxiliary wheel 24 is located on the right side of the two-wheeled motorcycle. The main body of the left support assembly 21 and the main body of the right support assembly 23 are both located below the base.

[0074] The left support assembly 21 is a main rod structure. Its right end has a support-base connector 25, and its left end has a support-auxiliary wheel connector 26. It also has two support-balance connectors 27. The support-base connector 25 of the left support assembly 21 is hinged to the left base-support connector 12 located on the right side of the base 1, allowing the left support assembly 21 to swing around the hinge axis. The direction of the hinge axis is the same as the front-rear direction of the motorcycle. The left auxiliary wheel 22 is hinged to the support-auxiliary wheel connector 26 at the left end of the left support assembly 21, allowing the left auxiliary wheel 22 to rotate around its own axis. When the auxiliary wheel is on the ground, the direction of its axis is the same as or at an acute angle to the left-right direction of the motorcycle (the specific angle changes dynamically depending on the swing of the support assembly).

[0075] Similarly, the right support assembly 23 is a main rod structure, on which a support-base connector 25, a support-auxiliary wheel connector 26, and a support-balance connector 27 are respectively provided. The support-base connector 25 at the left end of the right support assembly 23 is hinged to the right base-support connector 13 located on the left side of the base 1, allowing the right support assembly 23 to swing around the hinge axis, the direction of which is the same as the front-rear direction of the two-wheeled motorcycle. The right auxiliary wheel 24 is hinged to the support-auxiliary wheel connector 26 at the right end of the right support assembly 23, allowing the right auxiliary wheel 24 to rotate around its own axis; when the auxiliary wheel is on the ground, the direction of its axis is the same as or at an acute angle to the left-right direction of the two-wheeled motorcycle.

[0076] The balance control assembly 3 includes a control body 32 and a control component 33. One end of the balance control assembly 3 has a control-external connector 37 that is hinged to the left base-control connector 14 on the base 1 to position the balance control assembly 3 on the base 1 and allow the balance control assembly 3 to swing about the hinge axis. The other end of the balance control assembly 3 has a control-external connector 37 that is indirectly connected to the left support assembly 21 through an auxiliary connecting rod 28.

[0077] The control component 33 and the control body 32 form a set of kinematic pairs for adjusting and supporting balance. The balance control component 3 adopts a linear drive unit.

[0078] In this embodiment, the adjustable connection assembly 4 includes a connection body 41 and a connection member 42. The connection body 41 and the connection member 42 of the adjustable connection assembly 4 are respectively provided with connection-external connectors 43, which are connected to the left support assembly 21 and the right support assembly 23 respectively via auxiliary connecting rods 28.

[0079] The connecting member 42 and the connecting body 41 form a kinematic pair for adjusting the supporting force and position. Under the action of a driving force, they can generate controllable force and position changes. The relative displacement between the connecting member 42 and the connecting body 41 can drive the relative displacement between the connecting-external connecting parts 43 on both sides of the adjustable connecting assembly 4. The microelectronic controller, according to a preset program or external instructions, provides the power source to drive the adjustable connecting assembly 4, thereby controlling the force and relative position between the connecting member 42 and the connecting body 41.

[0080] In this embodiment, the method of controlling the vehicle's balance and support is the same as... Figure 1 The implementation examples are similar and will not be repeated here.

[0083] This embodiment and Figure 4 , Figure 5The embodiments are basically the same, except that the adjustable connection component 4 of the execution component adopts an angle drive unit; the adjustable connection component 4 includes a connection body 41 and a connection member 42. One end of the connection body 41 and the connection member 42 is respectively provided with a connection-external connector 43. The two connection-external connectors 43 are connected to the support-balance connection member 27 of the left support component 21 and the support-balance connection member 27 of the right support component 23 through an auxiliary connecting rod 28. This allows the adjustable connection component 4 to control the raising and lowering of the auxiliary wheels on both sides to support the ground by changing the relative distance between the two connection-external connectors 43. Furthermore, the left support component 21 and the right support component 23 are connected by the adjustable connection component 4, so that when external factors such as uneven ground cause displacement of one auxiliary wheel and change of ground support force, the support force of the other auxiliary wheel also changes accordingly, thereby keeping the support forces on both sides similar.

[0084] Because this invention creatively sets an adjustable connecting component 4 between the left support component 21 and the right support component 23, so that the left support component 21 and the right support component 23 are linked, when the road surface is uneven, the change in the support force of the auxiliary wheel on one side can be transmitted to the other side through the mechanical balancing mechanism, so as to reduce the difference in the support force of the two auxiliary wheels on the ground. Even without the active control of the microelectronic controller, the vehicle can be effectively suppressed to prevent tilting. When the vehicle tilts excessively, under the active control of the microelectronic controller, the drive balance control component applies a reverse balancing torque, further improving the anti-tipping ability.

[0085] The interconnected auxiliary support system described in this application can be applied in the field of auxiliary wheel support technology for two-wheeled vehicles, including but not limited to ordinary two-wheeled motorcycles, two-wheeled electric motorcycles, and two-wheeled electric bicycles.

The descriptions of the embodiments above are only for the purpose of helping to understand the methods and core ideas of this application; at the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application, which do not depart from the spirit and essence of this application. The content of this specification should not be construed as a limitation of this application.
