Description

Technical Field

[0001] This invention belongs to the field of two-wheeled vehicles. Background Technology

[0002] Traditional single kickstands for two-wheeled vehicles are limited to providing mechanical parking support and are purely passive components. With the development of intelligent and connected two-wheeled vehicles, especially the increasing demand for standardized vehicle safety management and usage procedures, the limitations of traditional single kickstands are becoming increasingly apparent.

[0003] In existing technologies, several improvements have been developed to give the kickstand a certain sensing capability. The most common solution is to install an angle sensor or a simple contact switch at the kickstand's pivot point to detect whether the kickstand is in the retracted position. This type of solution can achieve a basic "anti-start-without-retracted" safety function, that is, when the kickstand is detected to be in the retracted position, the vehicle's motor output power is limited.

[0004] However, these solutions are limited in functionality and have significant shortcomings: they can only recognize two coarse-grained states, "retracted" and "not retracted," and cannot effectively distinguish the actual situation in the "not retracted" state. For example, when the stand is lowered, the system cannot determine whether the vehicle has been reliably parked on the stand, whether the stand legs are effectively in contact and bearing weight, whether the user is still sitting in the vehicle after parking, or whether the vehicle has tipped over to the other side.

[0005] These complex scenarios are crucial for shared vehicle operations, high-level safety alerts, and accurate vehicle usage status management, but existing technologies lack effective mechanical and sensor designs to acquire and differentiate this information. Summary of the Invention

[0006] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a smart single support and control method for two-wheeled vehicles, which integrates a mechanical structure of elastic support and linkage transmission, so that the support foot of the single support leg can generate graded mechanical displacement according to the different supporting forces of the ground.

[0007] Technical Solution: To achieve the above objectives, the present invention provides a smart single support for a two-wheeled vehicle, comprising a fixed base, a turntable, and a single support leg. The fixed base is fixed to the vehicle frame, the turntable is rotatably mounted on the fixed base, and the upper end of the single support leg is fixedly connected to the turntable. The turntable has a permanent magnet mounting hole, and a permanent magnet is fixed in the permanent magnet mounting hole. A sensor mounting groove is provided on the side of the fixed base near the turntable, and a Hall sensor is fixed in the sensor mounting groove. When the single support leg is in a laterally folded state, the sensor mounting groove is aligned with the permanent magnet mounting hole in which the permanent magnet is mounted.

[0008] The controller determines the status of the single kickstand of the electric bicycle based on the status of the Hall sensor. In the start-up state, when the controller determines that the single kickstand is in the folded-down state, the electric bicycle motor will immediately provide power if the user applies the throttle. When the controller determines that the single kickstand is not in the folded-down state, the electric bicycle motor will not provide power even if the throttle is applied.

[0009] Furthermore, a guide seat is integrally provided at the end of the single support leg. A support foot is connected to the lower side of the guide seat through a support spring. A pair of guide rods extending along the length of the single support leg are integrally connected to the upper side of the support foot. The upper end of the guide rods is guided upward through the guide hole on the guide seat and then fixedly connected to the linkage block. Under the push of the support spring, the linkage block is limited to contact the upper end of the guide seat.

[0010] A limiting protrusion is integrally fixedly connected to the upper end of the support leg. In the initial state, there is a gap between the limiting protrusion and the guide seat. A linkage rod extending along the extension direction of the single support leg is fixedly connected to the linkage block. A linkage rod guide seat is fixedly installed on one side of the upper part of the single support leg. The upper end of the linkage rod moves upward and passes through the guide hole on the linkage rod guide seat. After the upper end of the linkage rod passes through the linkage rod guide seat, a shuttle-shaped block is vertically fixedly connected to it. When the single support leg is in a vertical support state, the pointed end of the shuttle-shaped block includes a first inclined surface and a second inclined surface that are symmetrically arranged vertically. A micro switch a and a micro switch b are fixedly installed on the lower side of the fixed seat through a micro switch bracket. A rocker arm for a inclined switch is provided below the micro switch a, and a rocker arm for a inclined switch b is provided above the micro switch b.

[0011] As the single support leg rotates and swings from the horizontal folded state to the vertical support state with the turntable, the second inclined surface of the pointed end of the spindle block rotates around the axis of the turntable until it just presses against the rocker arm of the inclined switch b, turning on the micro switch b. At this time, there is just a gap between the first inclined surface of the pointed end of the spindle block and the rocker arm of the inclined switch a.

[0012] Furthermore, when the support leg is in a vertical support state and the ground support force is zero or less than F, the support force on the support leg is insufficient to overcome the support force of the support spring, and the shuttle block does not move; when the support leg is in a vertical support state and the ground support force is greater than F and less than F, the support force on the support leg overcomes the thrust of the support spring, and there is still a distance between the upper end of the protrusion and the guide seat, so that the shuttle block moves upward relative to each other, and the second inclined surface of the tip of the shuttle block releases the b inclined switch rocker upward, but the first inclined surface of the tip of the shuttle block has not yet touched the a inclined switch rocker.

[0013] When the support leg is in a vertical support state and the ground support force is greater than F, the support force on the support leg completely overcomes the support spring thrust, and the protrusion moves upward relative to the support leg until it reaches the limit contact guide seat; the shuttle block moves upward relative to the support leg, and at the same time the second inclined surface of the tip of the shuttle block releases the b inclined switch rocker plate upward, the first inclined surface of the tip of the shuttle block touches and presses the a inclined switch rocker plate upward, so that the a micro switch is turned on.

[0014] Furthermore, when the kickstand is in a vertical support state, the electric vehicle is normally parked on a horizontal surface, and no one is sitting on the electric vehicle, the ground support force on the kickstand falls within the range between F and F; when the kickstand is in a vertical support state, the electric vehicle is normally parked on a horizontal surface, and someone is sitting on the electric vehicle, the ground support force on the kickstand is significantly greater than F.

[0015] Furthermore, a protective shell is provided on the outside of each support leg to cover the linkage rod.

[0016] Furthermore, the a-angle rocker switch and the b-angle rocker switch are arranged symmetrically, one above the other.

[0017] The controller determines whether the electric bicycle's kickstand is folded horizontally or not based on the status of the Hall sensor. When the user finishes riding, the controller determines that the user has just dismounted based on a sudden decrease in the magnetic field strength detected by the Hall sensor in the sensor mounting slot and the subsequent activation signal of the microswitch (b). It then rotates the kickstand from the folded horizontal position to a fully vertical support position. Next:

[0018] If micro switch b changes from on to off, and micro switch a is not on, then it is determined that the user has parked the car normally and left.

[0019] If micro switch b changes from ON to OFF and micro switch a enters ON state, it is determined that the user is still riding the electric bicycle while the bicycle is parked and resting with both feet off the ground.

[0020] If microswitch b remains in the on state for an extended period, it is determined that the electric bicycle is in a tilted state.

[0021] Beneficial effects: This invention integrates a mechanical structure of elastic support and linkage transmission, enabling the support leg of a single support to generate graded mechanical displacements based on the varying ground support force. This displacement is ultimately converted through a linkage rod into three different operating states of the shuttle block on two opposing microswitches: no activation of any of them, activation of only one, or activation of the other. This refines the ambiguous "support state" into three precise states that can be distinguished by electrical signals, providing a foundation for subsequent intelligent judgment.

[0022] An innovative logic judgment method based on multi-sensor signal fusion: A control method is proposed that combines the signals detected by the Hall sensor to measure the folding angle of a single support with the signals detected by two microswitches to measure the force level of the support, and performs timing and combinational logic analysis. By analyzing the series of signal events and their logical combinations, such as "magnetic field signal change → switch b on / off → switch a on / off", the controller can not only determine whether the single support is "folding" or "standing", but also further distinguish between various complex scenarios such as "standing and the vehicle is stationary with no load", "standing and the user is still on the vehicle", and "standing but not touching the ground and the vehicle is tipping over", achieving a deep state perception that far exceeds simple position detection.

[0024] Figure 2 This is a schematic diagram showing two states of this device;

[0025] Figure 3 This is a schematic diagram of the entire device. Detailed Implementation

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] As shown in the attached diagram. Figures 1 to 3 The illustrated intelligent single kickstand for a two-wheeled vehicle includes a fixed base 2, a turntable 5, and a single kickstand leg 10. The fixed base 2 is fixed to the vehicle frame. The turntable 5 is rotatably mounted on the fixed base 2. The upper end of the single kickstand leg 10 is fixedly connected to the turntable 5. The turntable 5 has permanent magnet mounting holes 4, and the permanent magnet is fixed in the permanent magnet mounting holes 4. A sensor mounting slot 16 is provided on the side of the fixed base 2 near the turntable 5, and a Hall sensor is fixed in the sensor mounting slot 16. When the single kickstand leg 10 is in a laterally folded state, the sensor mounting slot 16 is aligned with the permanent magnet mounting hole 4 where the permanent magnet is mounted. When the single kickstand leg rotates to the folded position, the permanent magnet and the Hall sensor face each other, the sensor senses a preset strong magnetic field and outputs a high / low level signal; when the single kickstand leg leaves the folded position, the magnetic field weakens or disappears, and the sensor signal state flips.

[0028] A guide seat 39 is integrally provided at the end of the single support leg 10. A support foot 37 is connected to the lower side of the guide seat 39 via a support spring 35. A pair of guide rods 36 extending along the length of the single support leg 10 are integrally connected to the upper side of the support foot 37. The upper ends of the guide rods 36 are guided upwards through guide holes on the guide seat 39 and then fixedly connected to a linkage block 34. Under the push of the support spring 35, the linkage block 34 is limited to contact the upper end of the guide seat 39. A protective shell 40 is provided outside the single support leg 10 to cover the linkage rod 28. The bottom of the support foot 37 can be covered with wear-resistant rubber to increase friction and dampen shock. The preload and elastic coefficient of the support spring 35 are carefully designed and are key physical parameters determining the values ​​of the trigger forces F1 and F2. For example, the elastic force of the support spring 35 at its free length is designed to support a portion of the vehicle's unloaded weight, and its selectable elastic coefficient k ranges from 20-50 N / mm.

[0029] The upper end of the support leg 37 is integrally fixedly connected to the limiting protrusion 38. In the initial state, there is a gap between the limiting protrusion 38 and the guide seat 39. The linkage block 34 is fixedly connected to the linkage rod 28 extending along the extension direction of the single support leg 10. The upper side of the single support leg 10 is fixedly provided with the linkage rod guide seat 9. The upper end of the linkage rod 28 moves upward through the guide hole on the linkage rod guide seat 9. After the upper end of the linkage rod 28 passes through the linkage rod guide seat 9, it is vertically fixedly connected to the spindle block 25. When the single support leg 10 is in the vertical support state, the pointed end 29 of the spindle block 25 includes a first inclined surface 29a and a second inclined surface 29b that are symmetrical.

[0030] Microswitches a21 and b22, arranged vertically opposite each other, are fixedly mounted on the lower side of the fixed base 2 via a microswitch bracket 26. A tilting switch rocker 23 is located below microswitch a21, and a tilting switch rocker 24 is located above microswitch b22. The tilting switch rocker 23 and tilting switch rocker 24 are symmetrically arranged vertically. Microswitches a21 and b22 are preferably small, waterproof, tactile microswitches with low triggering force and sensitive response. The microswitch bracket 26 ensures the accuracy and stability of the relative positions of the two switches. The key working principle of this invention lies in the two-stage mechanical transmission of force through the rotation of the single support leg and the force applied to the support foot, ultimately transforming it into different states of action of the shuttle block 25 on the two microswitches a2 and b2, thereby outputting a combined electrical signal. The controller can accurately determine the real-time state of the single support and the vehicle's posture by analyzing the combination and timing of the three signals from the Hall sensor, microswitch a21, and microswitch b22.

[0031] As the single support leg 10 rotates and swings from the horizontal folded state to the vertical support state with the turntable 5, the second inclined surface 29b of the pointed end 29 of the spindle block 25 rotates around the axis of the turntable 5 until it just presses against the inclined switch rocker 24, so that the micro switch 22 is turned on. At this time, there is just a gap 27 between the first inclined surface 29a of the pointed end 29 of the spindle block 25 and the inclined switch rocker 23.

[0032] When the support leg 37 is in a vertical support state and the ground support force it receives is zero or less than F1, the support force received by the support leg 37 is insufficient to overcome the support force of the support spring 35, and the shuttle block 25 does not move.

[0033] When the support leg 37 is in a vertical support state, the ground support force it receives is greater than F1 and less than F2. The support force received by the support leg 37 overcomes the thrust of the support spring 35. There is still a distance between the upper end of the protrusion 38 and the guide seat 39, so that the shuttle block 25 moves upward relative to each other. This causes the second inclined surface 29b of the tip end 29 of the shuttle block 25 to release the inclined switch rocker 24 upward. However, the first inclined surface 29a of the tip end 29 of the shuttle block 25 has not yet touched the inclined switch rocker 23.

[0034] When the support leg 37 is in a vertical support state and the ground support force it receives is greater than F2, the support force received by the support leg 37 completely overcomes the thrust of the support spring 35, and the protrusion 38 moves upward relative to the support leg 37 to the limit contact guide seat 39; the shuttle block 25 moves upward relative to the support leg 37. At the same time, the second inclined surface 29b of the tip end 29 of the shuttle block 25 releases the inclined switch rocker 24 upward, and the first inclined surface 29a of the tip end 29 of the shuttle block 25 touches and presses the inclined switch rocker 23, so that the micro switch 21 is turned on.

[0035] Here, F1 and F2 are two key force thresholds. F1 can be set slightly greater than the expected ground support force on the support leg 37 when the single support leg is supporting an empty vehicle (without passengers), for example, it can be the force corresponding to 1 / 4 to 1 / 3 of the vehicle's net weight. F2 is set significantly greater than F1, typically corresponding to the force exerted on the support leg by the additional weight borne by the single support leg (approximately equivalent to part of the user's weight) and the vehicle's own weight when the user is sitting in the vehicle, for example, it can be 1.5 to 3 times the value of F1. The values ​​of F1 and F2 can be precisely calibrated by selecting the spring and designing the initial gap between the lug 38 and the guide seat 39.

[0036] When the support leg 37 is in a vertical support state, and the electric vehicle is normally parked on a horizontal surface and no one is sitting on the electric vehicle, the value of the ground support force on the support leg 37 falls within the range between F1 and F2, and is preferably in the middle between F1 and F2.

[0037] When the support leg 37 is in a vertical support state, the electric vehicle is normally parked on a horizontal surface, and when a person is sitting on the electric vehicle, the ground support force on the support leg 37 is significantly greater than F2.

[0038] The fixed base 2 has a sleeve hole 3 at its axis. A rotating cylinder 12 is coaxially mounted on the turntable 5. The end of the rotating cylinder 12 has a limiting outer edge 14. The rotating cylinder 12 is coaxially rotatably fitted into the sleeve hole 3. The rotating cylinder 12 has several dividing grooves 13 arranged in a circumferential array along the axial direction, which divide the rotating cylinder 12 into several petals. The outer ring of the limiting outer edge 14 has a conical chamfer. During assembly, as the limiting outer edge 14 of one section of the rotating cylinder 12 is coaxially inserted into the sleeve hole 3, the rotation formed by the petals... The rotating cylinder 12, guided by the chamfered conical surface on the limiting outer edge 14, elastically deforms and contracts inward, allowing it to smoothly fit into the sleeve hole 3. The upper end of the single support leg 10 is provided with a bolt through hole 6 and a positioning hole 18. The upper end of the single support leg 10 is engaged between two limiting protrusions 19 on the fixed seat 2, and the positioning pin 17 on the fixed seat 2 is inserted into the positioning hole 18. The assembly also includes a locking bolt 7 and a nut 1. The stud of the locking bolt 7 passes through the bolt through hole 6 and the rotating cylinder 12 in sequence, while the nut 1 is locked and pressed against the end of the rotating cylinder 12. This assembly structure constitutes a compact, reliable, and easy-to-install rotating pivot. The elastic flap design of the rotating cylinder 12 allows it to generate a certain rebound tension after being pressed into the sleeve hole of the fixed seat 2. Combined with the tightening of the locking bolt 7 and the nut 1, it effectively eliminates axial movement clearance, ensuring smooth and secure rotation of the turntable 5, while its structural strength is sufficient to withstand the complex load transmitted by the single support leg 10. The engagement of the positioning pin 17 and the positioning hole 18 prevents circumferential misalignment between the single support leg 10 and the fixed base 2, ensuring assembly accuracy.

[0039] This solution is used in the shared electric bicycle sector. Specific control methods are as follows:

[0040] When a user needs to use the vehicle, as the single support leg 10 rotates from a vertical support state to a horizontally folded state with the turntable 5, the Hall sensor in the sensor mounting slot 16 and the permanent magnet mounting hole 4 with the permanent magnet installed change from being offset to being aligned with each other, so that the Hall sensor senses a specific intensity of magnetic field, and then the controller determines whether the single support leg 10 of the electric bicycle is in a horizontally folded state or not folded state based on the state of the Hall sensor.

[0041] When the controller determines that the single support leg 10 is in a folded-down position, if the user applies the throttle, the electric bicycle's motor will immediately provide power, allowing the electric bicycle to start smoothly.

[0042] If the controller determines that the single kickstand 10 is not in the folded state, the electric bicycle's motor will not provide power even if the user applies the throttle, effectively preventing the electric bicycle from starting when the single kickstand 10 is not in the folded state, thereby improving safety.

[0043] When the user finishes riding, as they dismount and rotate the single support leg 10 from the folded-out position to the vertical support position with the turntable 5, the second inclined surface 29b of the pointed end 29 of the spindle block 25 rotates around the axis of the turntable 5 until it presses against the inclined switch rocker 24, activating the micro switch 22. At this moment, the controller determines that the user has just dismounted and rotated the single support leg 10 from the folded-out position to the fully vertical support position based on the combination of the sudden decrease in magnetic field strength sensed by the Hall sensor in the sensor mounting slot 16 (indicating that the single support has left the folded-out position) and the subsequent activation signal of the micro switch 22. This timing logic effectively distinguishes between "operating the single support" and other situations that may cause changes in the sensor signal.

[0044] The user then slightly tilts the electric bicycle towards the side of the single support leg 10, causing the support foot 37 facing the single support leg 10 to contact the ground. At this time, the ground support force on the support foot 37 is between F1 and F2. The support force on the support foot 37 overcomes the thrust of the support spring 35, and the shuttle block 25 moves upward. The second inclined surface 29b of the pointed end 29 of the shuttle block 25 releases the b-angle switch rocker 24 upward, but the first inclined surface 29a of the pointed end 29 of the shuttle block 25 has not yet touched the a-angle switch rocker 23. At this time, the controller determines that the user has parked normally and left based on the b micro switch 22 changing from on to off and the a micro switch 21 not being on. This state (b off, a off) is defined as "safe parking, user has left the vehicle" state, and the controller can end the billing or send a successful return signal accordingly.

[0045] If the user places the support leg 37 of the single support leg 10 of the electric bicycle on the ground, but the user is still riding the electric bicycle and resting with both feet off the ground, the ground support force F2 on the support leg 37 is significant. The support force on the support leg 37 completely overcomes the thrust of the support spring 35. The protrusion 38 moves upward relative to the support leg 37 and reaches the limit contact guide seat 39. The shuttle block 25 moves upward relative to the support leg 37. At the same time, the second inclined surface 29b of the pointed end 29 of the shuttle block 25 releases the inclined switch rocker 24 upward, and the first inclined surface 29a of the pointed end 29 of the shuttle block 25 touches and presses the inclined switch rocker 23, so that the micro switch 21 is turned on. At this time, the controller determines that the user is still riding the electric bicycle with both feet off the ground while the bicycle is parked, based on the change of the micro switch 22 from on to off and the micro switch 21 entering the on state. This behavior is very dangerous and needs to be notified to the user of the dangerous behavior through the horn on the vehicle. This state (b disconnected, a open) is the core basis for detecting "dangerous riding".

[0046] If, after parking, the user has rotated and swung the single support leg 10 from a horizontally folded state to a fully vertically supported state with the turntable 5, but the electric bicycle is not stable and tilts to the side without the single support leg 10, and the user does not immediately pick up the electric bicycle and leaves, the support foot 37 of the single support leg 10 is not in contact with the ground; the micro switch 22 is in a prolonged on state (e.g., continuously on for more than 5-10 seconds). The controller determines that the electric bicycle is tilted based on the prolonged on state of the micro switch 22, and needs to immediately notify the user or maintenance personnel for handling. This state is used to detect "vehicle tilting," improving the safety monitoring scenario.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The intelligent mono-strut for two-wheeled vehicles of claim 2, wherein: When the ground support force received by the supporting leg (37) in the vertical supporting state is zero or less than F1, the support force received by the supporting leg (37) is insufficient to overcome the support force of the supporting spring (35), and the shuttle-shaped block (25) does not act; When the ground support force received by the supporting leg (37) in the vertical supporting state is greater than F1 and less than F2, the support force received by the supporting leg (37) overcomes the pushing force of the supporting spring (35), and the upper end of the protruding block (38) is still away from the guide seat (39), so that the shuttle-shaped block (25) moves upward relatively, the second inclined surface (29b) of the sharp end (29) of the shuttle-shaped block (25) releases the b inclined switch rocker (24) upward, but the first inclined surface (29a) of the sharp end (29) of the shuttle-shaped block (25) has not touched the a inclined switch rocker (23); When the ground support force received by the supporting leg (37) in the vertical supporting state is greater than F2, the support force received by the supporting leg (37) completely overcomes the pushing force of the supporting spring (35), and the protruding block (38) follows the supporting leg (37) to displace upward relatively to the limit contact guide seat (39); the shuttle-shaped block (25) moves upward relatively, the second inclined surface (29b) of the sharp end (29) of the shuttle-shaped block (25) releases the b inclined switch rocker (24) upward, and at the same time, the first inclined surface (29a) of the sharp end (29) of the shuttle-shaped block (25) touches and presses the a inclined switch rocker (23) upward, so that the a micro switch (21) is turned on.

4. The intelligent mono-strut for two-wheeled vehicles of claim 3, wherein: When the supporting leg (37) is in the vertical supporting state, the electric vehicle normally stops on the horizontal plane, and when there is no person on the electric vehicle, the ground support force received by the supporting leg (37) falls within the interval range between F1 and F2; When the supporting leg (37) is in the vertical supporting state, the electric vehicle normally stops on the horizontal plane, and when there is a person on the electric vehicle, the ground support force received by the supporting leg (37) is significantly greater than F2.

5. A two-wheeler intelligent mono-strut as claimed in claim 4, wherein: The single supporting leg (10) is provided with a protective shell (40) which covers the linkage rod (28).

6. The intelligent mono-strut for two-wheeled vehicles of claim 4, wherein: The a inclined switch rocker (23) and the b inclined switch rocker (24) are arranged in an upper-lower relative symmetry.

7. The control method of the intelligent single support of the two-wheeled vehicle according to claim 5, characterized in that: The controller determines whether the single supporting leg (10) of the electric bicycle is in the transverse folding state or the non-folding state based on the state of the Hall sensor; When the user finishes riding, the controller determines that the user has just got off the vehicle and has made the action of rotating and swinging the single supporting leg (10) with the rotating disc (5) from the transverse folding state to the completely vertical supporting state based on the combination of the sudden decrease of the magnetic field strength sensed by the Hall sensor in the sensor installation slot (16) and the subsequent on signal of the b micro switch (22); Next: If the b micro switch (22) changes from on to off, and the a micro switch (21) is not on, it is determined that the user has normally parked and left; If the b micro switch (22) changes from on to off, and the a micro switch (21) enters the on state, it is determined that the user is still riding on the electric bicycle in the parked state and resting with both feet off the ground. If the b micro switch (22) is in the long time on state, it is determined that the electric bicycle is in the dumping state.
