Description

Technical Field

[0001] The invention relates to the technical field of two-wheeled vehicle kickstands, and in particular to an automatic kickstand device and a control method thereof. Background Art

[0002] The electric vehicle kickstand is a supporting device used to fix the vehicle when parking. A single stand refers to an independent supporting device on one side of an electric vehicle, usually located on the left or right side of the vehicle body. It fixes the vehicle by contacting the ground at a single point and is suitable for short-term temporary parking. A traditional electric vehicle single stand is usually composed of a welded combination of a support member, a footrest, a spring column, a spring, and a pedal assist member. The support member is divided into a connecting portion, a supporting portion, and an extension portion, and is integrally formed with the kickstand. When in use, the user parks the vehicle by stepping on it or pulling it by hand. Some high-end vehicles use an aluminum alloy bracket in conjunction with a spring return mechanism to form a parking device.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0025] Embodiment 1: The present invention provides an automatic foot support device, referring to Figures 1 to 10 As shown, the automatic foot support device includes a supporting mechanism 1, a driving mechanism 2, a switching mechanism 3 and a telescopic foot support mechanism 4.

[0026] The driving mechanism 2 is fixedly arranged on the supporting mechanism 1 , the telescopic foot support mechanism 4 is rotatably arranged on the supporting mechanism 1 , and the output end of the driving mechanism 2 is transmission-connected to the telescopic foot support mechanism 4 via the adapter mechanism 3 .

[0027] When parking, the driving mechanism 2 drives the telescopic foot support mechanism 4 to rotate forwardly through the adapter mechanism 3. At the same time, the telescopic foot support mechanism 4 extends until the telescopic foot support mechanism 4 is fully opened and extended to contact the ground.

[0028] The telescopic footrest mechanism 4 in the open and extended state has a long support structure, which can effectively ensure the parking stability.

[0029] When releasing the parking brake, the drive mechanism 2 drives the telescopic footrest mechanism 4 to rotate in the reverse direction through the transfer mechanism 3. At the same time, the telescopic footrest mechanism 4 retracts until the telescopic footrest mechanism 4 is completely retracted and folded.

[0030] The telescopic footrest mechanism 4 in the retracted and folded state has a relatively short overall support structure, which can effectively save space.

[0031] During the above-mentioned parking and releasing of the parking brake processes, the power for the rotation and telescopic movement of the telescopic footrest mechanism 4 is provided by the drive mechanism 2, which can achieve automatic operation and is more convenient to use.

[0032] Embodiment 2 Embodiment 2 is based on Embodiment 1: As Figures 1 to 10 As shown, the telescopic footrest mechanism 4 includes a telescopic footrest assembly 41 and a transmission gear disk 42. The support mechanism 1 includes a support piece 13. The transmission gear disk 42 is rotatably arranged on the support piece 13. The transfer mechanism 3 is connected to the transmission gear disk 42, and the connection end of the telescopic footrest assembly 41 is connected to the transmission gear disk 42.

[0033] During operation, the drive mechanism 2 is started, and drives the transmission gear disk 42 to rotate relative to the support piece 13 through the transfer mechanism 3. The telescopic footrest assembly 41 rotates synchronously therewith, thereby realizing opening and folding.

[0034] Specifically, the drive mechanism 2 drives the entire telescopic footrest assembly 41 to rotate forward and backward by 95~115° through the transfer mechanism 3.

[0035] As an optional implementation manner, the telescopic footrest assembly 41 includes a single-support upper cavity rod 411, a single-support lower cavity assembly and a transmission assembly.

[0036] The connection end of the single-support upper cavity rod 411 is rotatably clamped on both sides of the support piece 13. Specifically, the connection end of the single-support upper cavity rod 411 includes two clamping plates arranged oppositely, and shaft holes for installing hinge shafts are provided on the clamping plates.

[0037] The transmission gear disk 42 is located between the two clamping plates. The end of the transfer mechanism 3 is provided with a hinge shaft, the hinge shaft passes through the shaft hole, and the transmission gear disk 42 is sleeved on the hinge shaft.

[0038] The single-support upper cavity rod 411 and the single-support lower cavity assembly are slidably connected along the axial direction. The single-support lower cavity assembly is connected to the transmission gear disk 42 through the transmission assembly. The transmission gear disk 42 is used to link the overall rotation movement of the telescopic footrest assembly 41 and the moving and telescopic movement of the single-support lower cavity assembly.

[0039] During use, the driving mechanism 2 drives the transmission gear plate 42 to rotate through the adapter mechanism 3, and the telescopic foot support assembly 41 rotates synchronously with the transmission gear plate 42. At the same time, the transmission assembly transmits the power of the adapter mechanism 3 to the single-support lower chamber assembly, so that the single-support lower chamber assembly slides axially along the single-support upper chamber rod 411, thereby realizing the movement and extension of the telescopic foot support assembly 41.

[0040] As an optional embodiment, the single-support lower chamber assembly includes a single-support lower chamber rod assembly 412 and a station head 413, the single-support lower chamber rod assembly 412 includes a single-support lower chamber rod 4121 and a fixed plate 4122 fixedly arranged at the end of the single-support lower chamber rod 4121, and the transmission assembly includes a bevel gear 414, a rotating rod 415 and a telescopic rod 416.

[0041] The guide end of the single-support upper cavity rod 411 is inserted into the resident head 413 , and the resident head 413 and the single-support upper cavity rod 411 are slidably matched.

[0042] The single-support lower cavity rod 4121 is fixedly connected to the inner side of the resident head 413 through the fixed plate 4122. The single-support lower cavity rod assembly 412 and the resident head 413 move synchronously. The single-support lower cavity rod 4121 is inserted into the single-support upper cavity rod 411 and slidably cooperates with the single-support upper cavity rod 411.

[0043] With such arrangement, a double sliding structure is formed between the single-bracing upper cavity rod 411 and the station head 413 and between the single-bracing lower cavity rod 4121 and the single-bracing upper cavity rod 411, so that the telescopic sliding action is more stable.

[0044] A sliding portion 4123 is disposed on the outer wall of the single-support lower cavity rod 4121 , and a guiding portion 4111 is disposed on the inner wall of the single-support upper cavity rod 411 at a position corresponding to the sliding portion 4123 , and the sliding portion 4123 and the guiding portion 4111 are slidably matched.

[0045] The sliding portion 4123 and the guiding portion 4111 cooperate with each other to effectively limit the moving trajectory of the single-support lower cavity rod 4121. Specifically, the sliding portion 4123 is a sliding bar arranged axially along the single-support lower cavity rod 4121, and the guiding portion 4111 is a guiding groove. The sliding bar and the guiding groove are slidably cooperated. Furthermore, the number of sliding portions 4123 is set to be multiple, which are evenly arranged along the circumferential direction on the outer wall of the single-support lower cavity rod 4121, and the number of guiding portions 4111 is the same as the number of sliding portions 4123, and corresponds one to one.

[0046] The bevel gear 414 is fixedly sleeved on the end of the rotating rod 415 and meshes with the transmission gear plate 42 . The bevel gear 414 and the rotating rod 415 rotate synchronously.

[0047] At the end of the single-support upper cavity rod 411 located in the middle of the two clamping plates, there is an installation hole 4112 axially penetrating. A bearing 417 is fixedly arranged in the installation hole 4112. The rotating rod 415 passes through the bearing 417 and is inserted into the single-support lower cavity rod 4121. The rotating rod 415 rotates synchronously with the bevel gear 414.

[0048] The bevel gear 414 can effectively change the transmission direction of power and transmit the rotational power of the transmission gear disk 42 to the rotating rod 415.

[0049] The telescopic rod 416 is rotatably arranged in the single-support lower cavity rod assembly 412. Specifically, for convenient installation, the fixed disk 4122 includes two D-shaped turntables inserted relatively. The two D-shaped turntables enclose an installation groove 4125 adapted to the installation end of the telescopic rod 416. The installation end of the telescopic rod 416 is rotatably arranged in the installation groove 4125.

[0050] The telescopic rod 416 is axially provided with an inner cavity, which is adapted to the rotating rod 415. The telescopic rod 416 is sleeved on the rotating rod 415 through the inner cavity. The telescopic rod 416 and the rotating rod 415 rotate synchronously. The telescopic rod 416 is axially slidably matched with the rotating rod 415. A spiral guiding groove 4161 is arranged on the outer wall of the telescopic rod 416. A fixed slider 4113 is arranged on the inner side of the single-support upper cavity rod 411. A strip-shaped guiding groove 4124 is axially opened on the outer wall of the single-support lower cavity rod 4121. The fixed slider 4113 passes through the strip-shaped guiding groove 4124 and is placed in the spiral guiding groove 4161. The fixed slider 4113 is slidably matched with the spiral guiding groove 4161.

[0051] During use, the transmission gear disk 42 drives the bevel gear 414 to rotate, and the rotating rod 415 and the telescopic rod 416 rotate synchronously. At this time, the spiral guiding groove 4161 and the fixed slider 4113 move relatively. Since the fixed slider 4113 is fixedly arranged on the single-support upper cavity rod 411, when the telescopic rod 416 rotates, it moves axially along itself, thereby driving the residence head 413 to move axially to achieve telescoping.

[0052] As an optional implementation manner, at least one first positioning connection portion 4114 is arranged at the connection end of the single-support upper cavity rod 411. A second positioning connection portion 421 is arranged at the position corresponding to the first positioning connection portion 4114 on the transmission gear disk 42. The first positioning connection portion 4114 is connected to the corresponding second positioning connection portion 421.

[0053] Specifically, the first positioning connection portion 4114 is set as a positioning groove, and the second positioning connection portion 421 is set as a positioning post. The positioning post is inserted into the positioning groove. Preferably, the number of the positioning posts and the positioning grooves is both set as two.

[0054] The positioning plug-in structure is adopted to facilitate disassembly and assembly while ensuring the synchronous rotation effect of the single support upper cavity rod 411 and the transmission gear plate 42.

[0055] As an optional embodiment, at least one rolling element 131 is arranged on the end face of the support plate 13 close to the transmission gear plate 42 in the circumferential direction. The rolling element 131 is a ball. An arc-shaped guide groove 422 is arranged on the transmission gear plate 42. The ball is adapted to the arc-shaped guide groove 422. The rolling element 131 is located in the arc-shaped guide groove 422 and can roll along the arc-shaped guide groove 422.

[0056] The rolling element 131 and the arc-shaped guide groove 422 cooperate with each other to effectively limit the rotation trajectory of the transmission gear plate 42 relative to the support plate 13, making its rotation process more stable.

[0057] As an optional implementation, the support mechanism 1 includes a motor mounting seat 11 and a support seat 12 , and the motor mounting seat 11 is disposed on the support seat 12 via threaded fasteners.

[0058] The driving mechanism 2 includes a driving motor 21 . The driving motor 21 is mounted on the motor mounting seat 11 . The output end of the driving motor 21 passes through the motor mounting seat 11 and the support seat 12 and is connected to the switching mechanism 3 .

[0059] A mounting seat is arranged on the bottom side of the support seat 12, and a support plate 13 is arranged on the mounting seat through threaded fasteners. A connecting hole is also arranged on the support seat 12, and a fixing plate 14 is installed at the position of the connecting hole. The fixing plate 14 is used to connect other structures.

[0060] As an optional embodiment, the adapter mechanism 3 includes connecting joints located at both ends and a universal joint 31 arranged between the two connecting joints, the two connecting joints are respectively used to connect the output end of the driving mechanism 2 and the transmission gear plate 42, and the number of universal joints 31 is set to at least one, which is set specifically according to actual needs.

[0061] Example 3 Embodiment 3 is based on any of the above embodiments: The automatic foot support device is electrically connected to a control device, such as Figure 11 As shown, the control device includes a central controller and a vehicle running state detection device, and the driving mechanism 2 and the vehicle running state detection device are both electrically connected to the central controller.

[0062] The vehicle running state detection device is used to detect the running state of the two-wheeled vehicle, so as to determine whether the vehicle is in a parking state. When the vehicle is in a parking state, the central controller controls the driving mechanism 2 of the automatic kick support device to start, so that the telescopic kick support mechanism 4 is opened and extended.

[0063] The control device can not only effectively control the operation of the automatic footrest device to achieve automatic parking, but also support the two-wheeled vehicle through the automatic footrest device during parking, ensuring stable parking.

[0064] Embodiment 4 Embodiment 4 is based on Embodiment 3: The vehicle operation state detection device includes a seat cushion gravity sensor. The seat cushion gravity sensor uses a pressure sensor and is embedded under the seat cushion to cover the main stress area, for detecting the load on the seat cushion. By detecting the load, it is determined whether the vehicle is in a riding state.

[0065] Optionally, multi-point pressure sensors can be set. Through multi-point detection, during actual application, the influence of local load caused by placing heavy objects on the seat cushion on the determination of the riding state can be excluded, improving the accuracy of the determination.

[0066] The vehicle operation state detection device includes a wheel movement sensor. The wheel movement sensor uses a speed / Hall sensor and is set near the motor hub or brake disc, for detecting the wheel rotation state. By detecting the wheel rotation state, it is determined whether the vehicle is in a stopped state.

[0067] Through the mutual cooperation of load detection and wheel movement detection, the parking state can be effectively determined, thus ensuring the control effect on the automatic footrest device.

[0068] As an optional implementation manner, the control device includes a parking state feedback device, and the parking state feedback device is electrically connected to the central controller.

[0069] The parking state feedback device includes at least one of a dashboard that can display information about the parking state, a seat cushion vibration device that can vibrate during parking, and a wheel lock or GPS positioning alarm device that can be activated during parking.

[0070] Through the parking state feedback device, the interaction between the vehicle and the user can be increased, effectively reminding the user that the vehicle is automatically parked.

[0071] Embodiment 5 Embodiment 5 is based on Embodiment 4: The present invention provides a control method for the automatic footrest device, as Figure 12 shown, the control method at least includes the following steps: Obtain the vehicle operation state; Judge whether the vehicle is in a parking state according to the vehicle operation state. If the vehicle is in a parking state, control the drive mechanism 2 of the automatic footrest device to start.

[0072] As an alternative embodiment, the obtaining of the vehicle running state includes obtaining the rotational speed of the wheels through the wheel rotation sensor, and the central controller determines whether the vehicle is in a stopped state according to the rotational speed of the wheels, where: If the rotational speed of the wheels is greater than zero, it is determined that the vehicle is in a running state; If the rotational speed of the wheels is equal to zero, it is determined that the vehicle is in a stopped state, and then the riding state of the vehicle is determined.

[0073] As an alternative embodiment, the obtaining of the vehicle running state includes obtaining the load on the vehicle seat through the seat gravity sensor. When the vehicle is in a stopped state, the central controller determines whether the vehicle is in an unridden state by comparing the load value of the vehicle with a threshold value, where: If the load value of the vehicle seat is greater than the threshold value, it is determined that someone is sitting on the seat and the vehicle is in a riding state; If the load value of the vehicle seat is not greater than the threshold value, it is determined that the vehicle is in an unridden state, and then the parking state of the vehicle is determined.

[0074] Optionally, the threshold value is set to 5 kg and is set according to the actual situation in the actual application process.

[0075] As an alternative embodiment, when the vehicle is in an unridden state, the central controller determines whether the vehicle is in a parked state by comparing the duration of the vehicle being in a stopped state with a first duration setting value and the duration of the vehicle being in an unridden state with a second duration setting value, where: If the duration of the vehicle being in a stopped state is not less than the first duration setting value and the duration of the vehicle being in an unridden state is not less than the second duration setting value, it is determined that the vehicle is in a parked state.

[0076] At this time, the automatic footrest device is controlled to start, and the telescopic footrest mechanism 4 rotates and extends to support the ground to complete parking.

[0077] Optionally, the first duration setting value is set to 3 seconds and the second duration setting value is 2 seconds, and they are set according to the actual situation in the actual application process.

[0078] As an alternative embodiment, after the parking action of the automatic footrest device is completed, the central controller controls the parking state feedback device to feedback the completion of parking (such as the dashboard displays the completion of parking, the seat vibration device vibrates, etc.).

[0079] After that, the central controller cuts off the vehicle power system to prevent accidental touch of the speed control handlebar, and activates the electronic lock or a prompt sound (such as a "click" sound).

[0080] Embodiment 6 Such asFigure 13 As shown, the control method of the present invention further includes a fault determination method for the automatic footrest device, as follows: (1) The central control system (central controller) is started; (2) The automatic footrest device is lowered; Or, check whether the automatic footrest device is retracted; (3) If the automatic footrest device has been retracted, determine whether the vehicle has wheel movement and the seat is unoccupied. If so, lower the footrest device. Otherwise, keep the automatic footrest device in the retracted state, and continue to determine whether the vehicle has wheel movement and the seat is unoccupied, and repeat the foregoing steps; If the automatic footrest device is not retracted, determine whether the vehicle is disarmed; (4) If the vehicle is disarmed, check whether the vehicle has wheel movement or the seat is occupied; (5) If the vehicle has no wheel movement and the seat is unoccupied, lower the automatic footrest device, and check whether the automatic footrest device has been lowered. If not, determine a fault; If the vehicle has wheel movement or the seat is occupied, retract the automatic footrest device; (6) Detect whether the automatic footrest device is retracted; (7) If the automatic footrest device has been retracted, detect whether the vehicle has wheel movement or the seat is occupied, and repeat the above steps; If the automatic footrest device is not retracted, determine a fault; (8) End.

[0081] The control method of the automatic footrest device further includes an abnormal fault handling method for different scenarios, as follows: Scenario 1: When the seat is pressed but not ridden (such as placing a heavy object on the seat): Through multi-point pressure detection, exclude local heavy objects, and combine wheel movement information to determine whether the vehicle is in a parked state.

[0082] If the wheel speed is equal to zero, the load value is greater than the threshold, the stop state duration exceeds the first duration setting value, and the non-riding state duration exceeds the second duration setting value, it is determined to be parked.

[0083] Scenario 2: When the automatic footrest device is not lowered but the vehicle is stationary: If there is no tilt sensor, detect whether the vehicle is in a free state (such as slight rolling back) through motor resistance feedback.

[0084] If the vehicle has no tilt and no one is sitting, the vehicle prompts the user to lower the automatic footrest device through interactive feedback.

[0085] Scenario 3: When a conflict occurs in the sensor (pressure drift of the seat gravity sensor): The zero point is calibrated regularly by the central controller (such as automatically correcting the no-load pressure when powered on each time).

[0086] During actual use, when a fault occurs, a redundant strategy is triggered, such as automatically powering off after 10 minutes by default.
