Description

Technical Field

[0001] The present 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] An electric vehicle kickstand is a support device used to secure the vehicle when parking. A single stand refers to an independent support device on one side of an electric vehicle, usually located on the left or right side of the vehicle body. It secures 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 welded together by a support member, a footrest, a spring column, a spring, and a step-assist member. The support member is divided into a connecting portion, a supporting portion, and an extending 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 combination with a spring return mechanism to form a parking device.

[0003] In order to ensure good parking stability, traditional electric vehicle single stands usually need to provide a foot stand of sufficient length. A longer foot stand takes up more space, and traditional electric vehicle single stands are parked by pedaling or hand pulling, which makes the parking operation more cumbersome and laborious.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] 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.

[0045] 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 .

[0046] When parking, the driving mechanism 2 drives the telescopic leg support mechanism 4 to rotate forward through the adapter mechanism 3. At the same time, the telescopic leg support mechanism 4 extends until the telescopic leg support mechanism 4 is fully opened and extended to contact the ground.

[0047] The telescopic foot support mechanism 4 in the open and extended state has a longer support structure, which can effectively ensure parking stability.

[0048] When the parking is released, the driving mechanism 2 drives the telescopic leg support mechanism 4 to rotate in the opposite direction through the adapter mechanism 3. At the same time, the telescopic leg support mechanism 4 retracts until the telescopic leg support mechanism 4 is completely folded and retracted.

[0049] The telescopic foot support mechanism 4 in the folded and retracted state has a shorter support structure as a whole, which can effectively save space.

[0050] During the aforementioned parking and unparking process, the power for the rotation and extension of the telescopic foot support mechanism 4 is provided by the driving mechanism 2, which can realize automatic movement and is more convenient to use.

[0051] Example 2

[0052] Example 2 is based on Example 1:

[0053] like Figures 1 to 10 As shown, the telescopic foot support mechanism 4 includes a telescopic foot support assembly 41 and a transmission gear disc 42, the support mechanism 1 includes a support plate 13, the transmission gear disc 42 is rotatably set on the support plate 13, the adapter mechanism 3 is connected to the transmission gear disc 42, and the connecting end of the telescopic foot support assembly 41 is connected to the transmission gear disc 42.

[0054] During operation, the driving mechanism 2 is started, and the transmission gear plate 42 is driven to rotate relative to the support plate 13 through the adapter mechanism 3, and the telescopic foot support assembly 41 rotates synchronously therewith, thereby realizing opening and folding.

[0055] Specifically, the driving mechanism 2 drives the telescopic foot support assembly 41 to rotate forward and backward as a whole within a range of 95-115 degrees through the adapter mechanism 3.

[0056] As an optional embodiment, the telescopic foot support assembly 41 includes a single support upper chamber rod 411, a single support lower chamber assembly and a transmission assembly.

[0057] The connecting end of the single-support upper cavity rod 411 can be rotatably clamped on both sides of the support plate 13. Specifically, the connecting end of the single-support upper cavity rod 411 includes two clamping plates arranged opposite to each other, and the clamping plates are provided with shaft holes for installing the hinge shaft.

[0058] The transmission gear disc 42 is located between the two clamping plates. A hinge shaft is provided at the end of the switching mechanism 3. The hinge shaft passes through the shaft hole, and the transmission gear disc 42 is sleeved on the hinge shaft.

[0059] The single-support upper chamber rod 411 and the single-support lower chamber assembly are connected in an axial sliding manner. The single-support lower chamber assembly is connected to the transmission gear plate 42 through the transmission assembly. The transmission gear plate 42 is used to link the overall rotation movement of the telescopic foot support assembly 41 and the movement and telescopic movement of the single-support lower chamber assembly.

[0060] During use, the driving mechanism 2 drives the transmission gear disc 42 to rotate through the adapter mechanism 3, and the telescopic foot support assembly 41 rotates synchronously with the transmission gear disc 42. At the same time, the transmission assembly transmits the power of the adapter mechanism 3 to the single-support lower chamber assembly, causing the single-support lower chamber assembly to slide axially along the single-support upper chamber rod 411, thereby realizing the movement and extension of the telescopic foot support assembly 41.

[0061] 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.

[0062] 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.

[0063] 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 slides with the single-support upper cavity rod 411.

[0064] With such arrangement, a double sliding structure is formed between the single-support upper cavity rod 411 and the station head 413 and between the single-support lower cavity rod 4121 and the single-support upper cavity rod 411, making the telescopic sliding action more stable.

[0065] A sliding portion 4123 is provided on the outer wall of the single-support lower cavity rod 4121 , and a guide portion 4111 is provided 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 guide portion 4111 are slidably matched.

[0066] 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 slides in cooperation with the guide groove. Furthermore, the number of sliding portions 4123 is set to be multiple, which are evenly arranged circumferentially on the outer wall of the single-support lower cavity rod 4121. The number of guiding portions 4111 is the same as the number of sliding portions 4123, and corresponds one to one.

[0067] 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.

[0068] The end of the single-support upper cavity rod 411 is located in the middle of the two clamping plates and is axially penetrated with a mounting hole 4112, in which a bearing 417 is fixedly installed, and the rotating rod 415 passes through the bearing 417 and is inserted into the interior of the single-support lower cavity rod 4121. The rotating rod 415 rotates synchronously with the bevel gear 414.

[0069] The use of the bevel gear 414 can effectively change the direction of power transmission, and transmit the rotational power of the transmission gear plate 42 to the rotating rod 415.

[0070] The telescopic rod 416 can be rotatably set in the single-support lower cavity rod assembly 412. Specifically, for easy installation, the fixed plate 4122 includes two D-shaped turntables that are relatively plugged in. The two D-shaped turntables form a mounting groove 4125 that is compatible with the mounting end of the telescopic rod 416. The mounting end of the telescopic rod 416 can be rotatably set in the mounting groove 4125.

[0071] The telescopic rod 416 is provided with an inner cavity along the axial direction, and the inner cavity 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 slides with the rotating rod 415 along the axial direction. The outer wall of the telescopic rod 416 is provided with a spiral guide groove 4161, and the inner side of the single-support upper cavity rod 411 is provided with a fixed slider 4113. The outer wall of the single-support lower cavity rod 4121 is provided with a strip guide groove 4124 along the axial direction. The fixed slider 4113 passes through the strip guide groove 4124 and is placed in the spiral guide groove 4161. The fixed slider 4113 slides with the spiral guide groove 4161.

[0072] During use, the transmission gear disc 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 guide groove 4161 and the fixed slider 4113 move relative to each other. Since the fixed slider 4113 is fixed to the single-support upper cavity rod 411, as the telescopic rod 416 rotates, it moves axially, thereby driving the resident head 413 to move axially to achieve telescoping.

[0073] As an optional embodiment, at least one first positioning connection portion 4114 is provided at the connecting end of the single-support upper cavity rod 411, and a second positioning connection portion 421 is provided at a position corresponding to the first positioning connection portion 4114 on the transmission gear plate 42, and the first positioning connection portion 4114 is connected to the corresponding second positioning connection portion 421.

[0074] Specifically, the first positioning connection portion 4114 is configured as a positioning groove, and the second positioning connection portion 421 is configured as a positioning post, which is inserted into the positioning groove. Preferably, the number of the positioning posts and the number of the positioning grooves are both two.

[0075] 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.

[0076] As an optional embodiment, at least one rolling element 131 is provided in the circumferential direction on the end face of the support plate 13 close to the transmission gear disc 42. The rolling element 131 is a ball. An arc-shaped guide groove 422 is provided on the transmission gear disc 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.

[0077] 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.

[0078] As an optional embodiment, the support mechanism 1 includes a motor mounting seat 11 and a support seat 12 , and the motor mounting seat 11 is set on the support seat 12 through threaded fasteners.

[0079] 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 .

[0080] A mounting seat is provided on the bottom side of the support seat 12, and a support plate 13 is provided on the mounting seat through a threaded fastener. A connecting hole is also provided 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.

[0081] 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. The number of universal joints 31 is set to at least one, which is set according to actual needs.

[0082] Example 3

[0083] Example 3 is based on any of the above examples:

[0084] 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.

[0085] The vehicle operation status detection device is used to detect the operation status 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 foot support device to start, so that the telescopic foot support mechanism 4 is opened and extended.

[0086] The control device can not only effectively control the action of the automatic kick support device to realize automatic parking, but also support the two-wheeled vehicle through the automatic kick support device during parking, so that the parking is stable.

[0087] Example 4

[0088] Example 4 is based on Example 3:

[0089] The vehicle operation status detection device includes a seat cushion gravity sensor, which adopts a pressure sensor. The seat cushion gravity sensor is embedded under the seat cushion, covering the main force-bearing area, and is used to detect the load-bearing capacity of the seat cushion. By detecting the load-bearing capacity, it is determined whether the vehicle is in a riding state.

[0090] Optionally, a multi-point pressure sensor can be provided. Through multi-point detection, in actual application, the influence of local load-bearing caused by placing heavy objects on the seat cushion on the riding state judgment can be eliminated, thereby improving the accuracy of the judgment.

[0091] The vehicle running state detection device includes a wheel movement sensor, which adopts a speed / Hall sensor. The wheel movement sensor is arranged near the motor hub or brake disc and is used to detect the wheel rotation state. By detecting the wheel rotation state, it is determined whether the vehicle is in a stopped state.

[0092] By cooperating with the load-bearing detection and the wheel movement detection, the parking state can be effectively determined, thereby ensuring the control effect of the automatic kickstand device.

[0093] As an optional implementation, the control device includes a parking state feedback device, and the parking state feedback device is electrically connected to the central controller.

[0094] The parking state feedback device includes at least one of an instrument panel that can display parking state information, a seat cushion vibration device that can vibrate when parking, a wheel lock that can be activated when parking, or a GPS positioning alarm device.

[0095] The parking state feedback device can increase the interaction between the vehicle and the user, and effectively remind the user that the vehicle is automatically parked.

[0096] Example 5

[0097] Example 5 is based on Example 4:

[0098] The present invention provides a control method for the automatic foot support device, such as Figure 12 As shown, the control method includes at least the following steps:

[0099] Get the vehicle running status;

[0100] Whether the vehicle is in a parking state is determined according to the vehicle running state. If the vehicle is in a parking state, the driving mechanism 2 of the automatic kickstand device is controlled to start.

[0101] As an optional embodiment, the acquiring of the vehicle running state includes acquiring the wheel rotation speed through the wheel movement sensor, and the central controller determines whether the vehicle is in a stopped state based on the wheel rotation speed, wherein:

[0102] If the wheel speed is greater than zero, the vehicle is judged to be in a running state;

[0103] If the wheel speed is equal to zero, it is determined that the vehicle is in a stopped state, and then the vehicle riding state is determined.

[0104] As an optional embodiment, the obtaining of the vehicle operating status includes obtaining the weight of the vehicle seat cushion through the seat cushion gravity sensor. When the vehicle is in a stopped state, the central controller determines whether the vehicle is in a non-riding state based on the comparison of the vehicle's weight value with a threshold value, wherein:

[0105] If the load-bearing value of the vehicle seat cushion is greater than the threshold, it is determined that the seat cushion is occupied and the vehicle is in a riding state;

[0106] If the load-bearing value of the vehicle seat cushion is not greater than the threshold, it is determined that the vehicle is in a non-riding state, and then the parking state of the vehicle is determined.

[0107] Optionally, the threshold is set to 5 kg, and is set according to actual conditions during actual application.

[0108] As an optional embodiment, when the vehicle is in an unridden state, the central controller determines whether the vehicle is in a parked state based on a comparison of the duration of the vehicle being in a stopped state with a first set duration value, and a comparison of the duration of the vehicle being in an unridden state with a second set duration value, wherein:

[0109] If the duration that the vehicle is in the stopped state is not less than the first duration setting value, and the duration that the vehicle is in the unridden state is not less than the second duration setting value, it is determined that the vehicle is in the parked state.

[0110] At this time, the automatic kick support device is controlled to start, and the telescopic kick support mechanism 4 is rotated, opened and extended to support the ground, thereby completing parking.

[0111] Optionally, the first time length setting value is set to 3 seconds, and the second time length setting value is set to 2 seconds. In actual application, the settings are made according to actual conditions.

[0112] As an optional implementation, when the automatic kickstand device completes the parking action, the central controller controls the parking status feedback device to feedback that parking is completed (such as the instrument panel displays parking completion, the seat cushion vibration device vibrates, etc.).

[0113] After that, the central controller cuts off the vehicle's power system to prevent accidental touching of the speed control handlebar, and activates the electronic lock or a prompt sound (such as a "click" sound).

[0114] Example 6

[0115] like Figure 13 As shown, the control method of the present invention also includes a fault determination method of the automatic kickstand device, as follows:

[0116] (1) The central control system (central controller) is started;

[0117] (2) lowering the automatic foot support device;

[0118] Alternatively, check whether the automatic kickstand device is retracted;

[0119] (3) If the automatic kickstand device is folded, determine whether the vehicle is moving and the seat is unoccupied. If so, lower the kickstand device. If not, keep the automatic kickstand device folded, continue to determine whether the vehicle is moving and the seat is unoccupied, and repeat the above steps.

[0120] If the automatic kickstand device is not retracted, determining whether the vehicle is disarmed;

[0121] (4) If the vehicle is disarmed, check whether the vehicle is moving or if there is someone on the seat;

[0122] (5) If the vehicle is not moving and there is no one on the seat, lower the automatic kickstand and check whether the automatic kickstand is lowered. If not, determine that it is faulty;

[0123] If the vehicle is moving or the seat is occupied, the automatic kickstand device is retracted;

[0124] (6) Detecting whether the automatic foot support device is retracted;

[0125] (7) If the automatic kickstand device has been retracted, check whether the vehicle is moving or there is someone on the seat, and repeat the pinching step;

[0126] If the automatic kickstand device is not retracted, a fault is determined;

[0127] (8) End.

[0128] The control method of the automatic kickstand device also includes abnormal fault handling methods in different scenarios, as follows:

[0129] Scenario 1:

[0130] When the saddle is compressed but not ridden (e.g. with a heavy object on it):

[0131] Through multi-point pressure detection, local heavy objects are eliminated, and combined with wheel movement information, it is determined whether the vehicle is in the parking state.

[0132] If the wheel speed is zero, the load-bearing value is greater than the threshold, and the stopping 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.

[0133] Scenario 2:

[0134] When the automatic kickstand is not lowered and the vehicle is stationary:

[0135] If there is no inclination sensor, the motor resistance feedback is used to detect whether the vehicle is in a free state (such as slight slipping).

[0136] If the vehicle is not tilted and no one is riding in it, the vehicle will prompt the user to lower the automatic kickstand device through interactive feedback.

[0137] Scenario 3:

[0138] When sensor conflict occurs (seat cushion G-sensor pressure drift):

[0139] The zero point is calibrated regularly by the central controller (e.g. automatic correction of the no-load pressure at each power-up).

[0140] In actual use, when a fault occurs, a redundancy policy is triggered, such as automatic power off after 10 minutes by default.
