This invention relates to the field of electric motorcycle support frames, specifically to a side support assembly and support device for an electric motorcycle. The side support assembly includes: a telescopic leg assembly fixed to the bottom of the frame; and a pressure control assembly connected to the telescopic leg assembly via a hydraulic pipe. When the seat is pressed, the pressure control assembly controls the telescopic leg assembly to be in a retracted state. When the seat is in a natural state, the control assembly controls it to be in a natural state, and the telescopic leg assembly is in a supported state.

Description

Technical Field

[0001] This invention relates to the field of electric motorcycle support frames, specifically to a side support assembly and support device for an electric motorcycle. Background Technology

[0002] Electric motorcycles, as an environmentally friendly and efficient means of transportation, are receiving increasing attention and use. The kickstands on electric motorcycles are an important auxiliary device, providing stable support when parked and preventing the vehicle from tipping over. The kickstands are typically located at the bottom of the vehicle. Traditional electric motorcycle kickstands are usually manual, requiring the rider to extend them by foot to stabilize the vehicle. When retracting the kickstands, the rider must forcefully lift them back to their original position. Existing kickstands have the following drawbacks:

[0003] 1. It cannot automatically fold down. If you forget to fold it down while riding, it is easy to cause the vehicle to hit the ground and tip over. Also, when the support legs are rusted or deformed, opening and closing them becomes difficult and strenuous.

[0004] 2. Electric motorcycles are relatively bulky, and turning around in narrow parking spaces requires pushing them back and forth, which is time-consuming and laborious. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a side support component and support device for electric motorcycles to solve the problems of existing support legs not being able to automatically retract, requiring effort to open and close, and being difficult to turn around in narrow spaces.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] A side support assembly for an electric motorcycle is provided. The electric motorcycle includes a frame and a seat. The side support assembly includes:

[0008] Telescopic leg assembly fixed to the bottom of the frame; and

[0009] A pressure control assembly connected to the telescopic leg assembly via a hydraulic pipe;

[0010] When the seat cushion is pressed, the pressure control assembly controls the telescopic leg assembly to be in a retracted state;

[0011] When the seat cushion is in its natural state, the control assembly is also in its natural state, and the telescopic leg assembly is in its supported state.

[0012] Furthermore, the telescopic leg assembly includes:

[0013] A mounting body fixed to the vehicle frame;

[0014] A first pressure cylinder fixed to the mounting body, the cavity of the first pressure cylinder being connected to the hydraulic pipe; and

[0015] A support leg that is slidably installed inside the first pressure cylinder;

[0016] When the pressure of the pressure control assembly changes, the portion of the support leg located inside the first pressure cylinder cavity can slide along the inner wall of the first pressure cylinder cavity.

[0017] Furthermore, a support foot is installed at the end of the telescopic end of the support leg.

[0018] Furthermore, the pressure control assembly includes:

[0019] A second pressure cylinder is fixed to the upper part of the vehicle frame and located below the driver's seat. The cavity of the second pressure cylinder is connected to the hydraulic pipe, and a cylinder head cover is installed at the end of the second pressure cylinder. The cross-section and volume of the second pressure cylinder are larger than those of the first pressure cylinder.

[0020] A piston rod is slidably mounted on one end of the second pressure cylinder cavity, and a support plate is mounted on the other end of the piston rod.

[0021] At least one pressure rod is mounted on the support plate, with its upper end abutting against the inner frame of the seat cushion; the upper end of the pressure rod is provided with a pressure plate; and

[0022] A spring with one end fixed to the support plate and the other end fixed to the cylinder head cover, and sleeved on the piston rod.

[0023] Furthermore, an electrically controlled valve is installed on the hydraulic pipe.

[0024] An electric motorcycle support device is provided, the support device including the electric motorcycle side support assembly as described above, and further including:

[0025] A mounting beam, one end of which is fixed to the mounting body or frame, and the other end of which is fixed to the frame; and

[0026] The support leg is connected to the mounting beam via a rotating assembly.

[0027] Furthermore, the rotating assembly includes:

[0028] A circular housing is provided at the lower end of the mounting beam. An end cap is installed at the lower opening end of the circular housing. Multiple first ball grooves are respectively opened at the bottom of the cavity of the circular housing and on the inner end face of the end cap.

[0029] A rotating body is rotatably installed inside the circular housing. The upper and lower end faces of the rotating body are respectively provided with a plurality of second ball grooves. The upper end face of the rotating body is provided with a first rotating shaft. Correspondingly, a rotating groove for the first rotating shaft to rotate is provided at the bottom of the cavity of the circular housing. The lower end face of the rotating body is provided with a second rotating shaft.

[0030] A plurality of balls distributed between the first ball groove and the second ball groove; and

[0031] A mounting base is fixed to the lower end of the second rotating shaft. A hinge seat that is hinged to the support leg is fixed on the mounting base. A return tension spring is installed between the mounting base and the support leg.

[0032] Furthermore, a recovery component is installed in the rotating assembly.

[0033] Furthermore, the recovery component includes:

[0034] A coil spring is installed between the rotating body and the circular housing.

[0035] Furthermore, limit seats are respectively installed at both ends of the hinge shaft of the support leg, and the limit seats abut against the mounting base:

[0036] A foot support rod is provided on the side of the support leg near the support assembly. The foot support rod has a bend that forms a fulcrum on the ground. A foot pedal is rotatably installed at the end of the foot support rod.

[0037] The beneficial effects of this invention are:

[0038] 1. By introducing a hydraulic control mechanism and a seat cushion press-triggered mechanism, the support legs can automatically retract when the seat cushion is pressed. In this way, no manual retraction is required. When the driver sits on the seat, the support legs can automatically retract, and when the driver leaves the seat, the support legs can automatically retract. This avoids the danger of the vehicle tipping over due to contact with the ground, and also solves the problem of the difficulty of manual retraction.

[0039] 2. The introduction of the support device makes it easier for electric motorcycles to turn around in confined spaces. By installing a rotating component between the crossbeam and the support legs, the support device can achieve a rotating function, allowing the entire vehicle to rotate while being supported. This allows the front or rear wheels to be lifted for turning, making it easier for the driver to adjust the vehicle's position and direction, solving the problem of time-consuming and laborious pushing the vehicle back and forth.

[0062] The following disclosure provides many different embodiments or examples for implementing different structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the invention. Furthermore, the invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0063] The present invention provides the following preferred embodiments: Example 1

[0064] refer to Figure 1 and Figure 9 A side support assembly for an electric motorcycle, the electric motorcycle including a frame and a seat, the side support assembly comprising:

[0065] Telescopic leg assembly 1 fixed to the bottom of the frame; and

[0066] Pressure control assembly 3 is connected to the telescopic leg assembly 1 via hydraulic pipe 2;

[0067] When the seat cushion is pressed, the pressure control assembly 3 controls the telescopic leg assembly 1 to be in a retracted state.

[0068] When the seat cushion is in its natural state, the control assembly is also in its natural state, and the telescopic leg assembly 1 is in its supported state.

[0069] The side support assembly for the electric motorcycle includes the following components:

[0070] Telescopic Leg Assembly 1: This assembly is fixed to the bottom of the electric motorcycle frame. It consists of a telescopic support leg 13 that can be extended or retracted as needed. The length of the support leg 13 can be adjusted as needed to provide appropriate support height.

[0071] Pressure control assembly 3: This assembly is connected to the telescopic leg assembly via hydraulic pipe 2. Pressure control assembly 3 controls the state of telescopic leg assembly 1 by controlling the pressure in the hydraulic system. According to the principle of communicating vessels, when the seat cushion is pressed, pressure control assembly 3 will cause telescopic leg assembly 1 to retract. When the seat cushion is in its natural state, pressure control assembly 3 will maintain the natural pressure, keeping telescopic leg assembly 1 in a supported state; that is, when the driver sits on the seat cushion, the support leg 13 can automatically retract, and when the driver leaves the seat cushion, the support leg 13 can automatically extend.

[0072] The operational procedure for implementing this side support component is as follows:

[0073] When the electric motorcycle needs to be parked, the driver leaves the seat, the pressure control assembly 3 returns to its original position, and the telescopic leg assembly 1 extends to provide support. At this time, the electric motorcycle can be parked stably without manually opening the support legs 13.

[0074] When the driver is ready to continue riding, he sits on the seat, and the pressure control assembly 3 works to control the retractable leg assembly 1 to retract.

[0075] Through the above implementation methods, the electric motorcycle side support assembly can achieve automatic extension and retraction functions, and control the state of the support leg 13 by the driver sitting or leaving the seat, providing a convenient and stable parking experience. Example 2

[0076] refer to Figures 3 to 5 As shown, the telescopic leg assembly 1 includes:

[0077] Mounting body 11 fixed to the vehicle frame;

[0078] A first pressure cylinder 12 is fixed to the mounting body 11, and the cavity of the first pressure cylinder 12 is connected to the hydraulic pipe 2; and

[0079] Support leg 13 is slidably installed inside the first pressure cylinder 12;

[0080] When the pressure of the pressure control assembly 3 changes, the portion of the support leg 13 located inside the cavity of the first pressure cylinder 12 can slide along the inner wall of the cavity of the first pressure cylinder 12.

[0081] The side support assembly for this electric motorcycle includes the following parts:

[0082] Mounting body 11: Mounting body 11 is fixed to the frame of the electric motorcycle and provides a mounting base for the support leg 13 assembly.

[0083] First pressure cylinder 12: The first pressure cylinder 12 is fixed on the mounting body 11 and is connected to the pressure control assembly 3 through the hydraulic pipe 2. The internal space of the first pressure cylinder 12 serves as the hydraulic cylinder cavity, used to control the extension and retraction of the support leg 13.

[0084] Support leg 13: The support leg 13 is slidably installed inside the first pressure cylinder 12. The bottom of the support leg 13 is used to provide support, and the top of the support leg 13 is in contact with the inner wall of the first pressure cylinder 12 and can slide along the inner wall of the cavity of the first pressure cylinder 12.

[0085] The operational procedure for implementing this side support component is as follows:

[0086] According to the principle of communicating vessels, when the pressure control assembly 3 controls the pressure change, the hydraulic oil pressure in the hydraulic pipe 2 also changes. It can be understood that the cross-section and volume of the second pressure cylinder 31 are larger than the cross-section and volume of the first pressure cylinder 12, so that the pressure control assembly 3 can control the extension and retraction of the support leg 13 with less effort.

[0087] Through the above implementation method, the side support assembly of the electric motorcycle can realize the extension and retraction function of the support leg 13. By linking the hydraulic pipe 2 and the first pressure cylinder 12, the pressure change of the hydraulic oil is controlled, thereby controlling the extension and retraction state of the support leg 13. The support leg 13 can slide along the inner wall of the cavity of the first pressure cylinder 12 to achieve stable support and retraction operation. This design can provide convenient operation and stable support effect, improve the convenience of use and parking safety of the electric motorcycle. Example 3

[0088] refer to Figures 3 to 5 As shown, a support foot 14 is installed at the end of the telescopic end of the support leg 13.

[0089] The electric motorcycle side support assembly has a support foot 14 installed at the end of the telescopic end of the support leg 13. The support foot 14 can further enhance the stability and support capacity of the support leg 13, and can protect the support leg 13 from being damaged by mud and water.

[0090] The implementation method is as follows:

[0091] A support foot 14 is installed at the end of the telescopic end of the support leg 13.

[0092] The support feet 14 can be made of soft materials, such as reinforced plastic or rubber, and can have a suitable length and shape to provide additional support area.

[0093] The support foot 14 can be shoe-shaped to ensure full contact with the ground and increase stability. It can have a non-slip surface to provide better grip.

[0094] The support foot 14 is connected to the end of the support leg 13 by a fixing device, which can be a bolt, pin or other suitable connection method to ensure a firm connection between the support foot 14 and the support leg 13.

[0095] Through the above implementation method, the telescopic end of the support leg 13 is equipped with a support foot 14, providing additional support area and stability for the electric motorcycle. This design enhances the load-bearing capacity of the support leg 13, making the electric motorcycle more stable and safer when parked, and also protects the end of the support leg 13. The design and connection method of the support foot 14 can be adjusted and optimized according to actual needs to adapt to different motorcycle models and usage environments. Example 4

[0096] refer to Figure 5 As shown, the pressure control assembly 3 includes:

[0097] A second pressure cylinder 31 is fixed on the upper part of the vehicle frame and located below the driver's seat. The cavity of the second pressure cylinder 31 is connected to the hydraulic pipe 2, and a cylinder head cover 32 is installed at the end of the second pressure cylinder 31. The cross-section and volume of the second pressure cylinder 31 are larger than those of the first pressure cylinder 12.

[0098] A piston rod 33 is slidably mounted on one end of the second pressure cylinder 31, and a support plate 34 is mounted on the other end of the piston rod 33;

[0099] At least one pressure rod 35 is mounted on the support plate 34 and its upper end abuts against the inner frame of the seat cushion; the upper end of the pressure rod 35 is provided with a pressure plate 351; and

[0100] A spring 36, with one end fixed to the support plate 34 and the other end fixed to the cylinder head cover 32, and sleeved on the piston rod 33.

[0101] The electric motorcycle side support assembly includes the following parts:

[0102] Second pressure cylinder 31: The second pressure cylinder 31 is fixed to the upper part of the frame, located below the driver's seat. It is connected to the hydraulic pipe 2 and its end is sealed by the cylinder head cover 32. The cross-section and volume of the second pressure cylinder 31 are larger than those of the first pressure cylinder 12.

[0103] Piston rod 33: Piston rod 33 is slidably mounted in the cavity of the second pressure cylinder 31. One end of piston rod 33 is connected to support plate 34, and the other end is slidably mounted in the cavity of the second pressure cylinder 31.

[0104] Support plate 34: The support plate 34 is installed at the lower end of the piston rod 33 and plays the role of pulling the piston rod 33.

[0105] Pressure bar 35: At least one pressure bar 35 is mounted on the support plate 34, and a pressure plate 351 is provided at its upper end. The pressure plate 351 abuts against or is fixedly connected to the inner frame of the seat cushion.

[0106] Spring 36: Spring 36 is sleeved on piston rod 33, with one end fixed to support plate 34 and the other end fixed to cylinder head cover 32. The function of spring 36 is to provide restoring force to piston rod 33 so that piston rod 33 returns to its original position while driving support leg 13 to retract. On the other hand, spring 36 also has the function of shock absorption for seat cushion, improving driving comfort.

[0107] Through the above implementation, the pressure control assembly 3 in the side support component of the electric motorcycle achieves control of the state of the support leg 13 through hydraulic pressure. When the driver rides the electric motorcycle, i.e., when the seat is pressed, the piston rod 33 moves downward, the volume of the second pressure cylinder 31 increases, and through the hydraulic pipe 2, the volume of the first pressure cylinder 12 decreases, thereby controlling the support leg 13 to retract; when the driver prepares to ride the electric motorcycle, i.e., the seat returns to its natural state, the spring 36 provides the restoring force to the piston rod 33, causing the volume of the second pressure cylinder 31 to decrease, and then causing the volume of the first pressure cylinder 12 to increase, thereby controlling the support leg 13 to extend and support the electric motorcycle.

[0108] This implementation uses hydraulic control to achieve automatic extension and retraction of the side support assembly. It can control the extension and retraction of the support leg 13 according to the state and pressure changes of the seat, providing stable support and increasing the safety and convenience of parking the electric motorcycle. Example 5

[0109] refer to Figure 2 As shown, an electrically controlled valve 21 is installed on the hydraulic pipe 2.

[0110] In this embodiment, the electrically controlled valve 21 controls the on / off state of the hydraulic pipe 2, and the specific implementation method is as follows:

[0111] The opening and closing of the electronically controlled valve 21 is controlled by detecting the rotation of the wheel. When the wheel rotation speed reaches the set value, the electronically controlled valve 21 closes, causing the hydraulic pipe 2 to disconnect. This means that the control assembly can no longer control the telescopic leg assembly 1, making driving safer. This is to prevent the instantaneous weightlessness of the electric motorcycle when going over speed bumps or potholes from reducing the pressure on the seat, which would cause the telescopic leg assembly 1 to be in the open state. The telescopic leg assembly 1 being in the open state during driving would be dangerous. Therefore, it is considered to design an electronically controlled valve 21 in the hydraulic pipe 2 to prevent the telescopic leg assembly 1 from opening during driving. Example 6

[0112] refer to Figure 1 , Figure 2 and Figure 6 As shown, an electric motorcycle support device includes the electric motorcycle side support assembly as described above, and further includes:

[0113] One end of the mounting beam 4 is fixed to the mounting body 11 or the vehicle frame, and the other end of the mounting beam 4 is fixed to the vehicle frame; and

[0114] The support leg 5 is connected to the mounting beam 4 via a rotating assembly 6.

[0115] In this embodiment, the support device includes the following components:

[0116] The electric motorcycle side support assembly in Examples 1 to 6 serves as a side support. However, for horizontal support, a support leg 5 is also required. The support leg 5 is naturally stored at the bottom of the frame. When needed, the support leg 5 is stepped down while the electric motorcycle is lifted up, which can support the electric motorcycle horizontally.

[0117] However, when riding, the front of the motorcycle is usually facing inwards. When you need to ride again, you need to turn the motorcycle around. This usually requires pushing the motorcycle around multiple times, which is time-consuming and laborious. Moreover, it is impossible to turn around in a small space. To address this issue, we added a rotating component 6 so that electric motorcycles can turn around on the spot, saving time and effort.

[0118] The rotating component 6 can be implemented in various ways, such as bearing rotation, sleeve, or collar shaft; it is understood that the rotating component 6 can be a conventional mechanical structure, and therefore will not be exhaustive. Example 7

[0119] refer to Figures 6 to 8 As shown, the rotating assembly 6 includes:

[0120] A circular housing 61 is provided at the lower end of the mounting beam 4. An end cap 611 is installed at the lower opening end of the circular housing 61. A plurality of first ball grooves 62 are respectively opened at the bottom of the cavity of the circular housing 61 and on the inner end face of the end cap 611.

[0121] A rotating body 63 is rotatably installed inside the circular housing 61. The upper and lower end faces of the rotating body 63 are respectively provided with a plurality of second ball grooves 631. The upper end face of the rotating body 63 is provided with a first rotating shaft 632. Correspondingly, a rotating groove 612 for the first rotating shaft 632 to rotate is provided at the bottom of the cavity of the circular housing 61. The lower end face of the rotating body 63 is provided with a second rotating shaft 633.

[0122] A plurality of balls 64 distributed between the first ball groove 62 and the second ball groove 631; and

[0123] A mounting base 65 is fixed to the lower end of the second rotating shaft 633. A hinge seat 66 is fixed on the mounting base 65 and hinged to the support leg 5. A return tension spring 67 is installed between the mounting base 65 and the support leg 5.

[0124] In this embodiment, the electric motorcycle support device includes the following components:

[0125] Circular housing 61: Circular housing 61 is located at the lower end of the mounting beam 4, has a lower open end, and is fitted with an end cover 611. Multiple first ball grooves 62 are provided in the bottom of the cavity of circular housing 61 and on the inner end face of end cover 611.

[0126] Rotating body 63: Rotating body 63 is rotatably installed inside the circular housing 61. Multiple second ball grooves 631 are respectively opened on the upper and lower end faces of rotating body 63. A first rotating shaft 632 is provided on the upper end face of rotating body 63, and a rotating groove 612 is correspondingly opened at the bottom of the cavity of circular housing 61 so that the first rotating shaft 632 can rotate therein. A second rotating shaft 633 is provided on the lower end face of rotating body 63.

[0127] Ball 64: Multiple balls 64 are distributed between the first ball groove 62 and the second ball groove 631 to reduce the friction between the rotating body 63 and the circular housing 61, so as to achieve smooth rotation.

[0128] Mounting base 65: Mounting base 65 is fixed to the lower end of the second rotating shaft 633 and is provided with a hinge seat 66 that is hinged to the support leg 5. A return spring 67 is installed between the mounting base 65 and the support leg 5 to provide a return force so that the support leg 5 is held in the initial position.

[0129] Through the above implementation method, the rotating component 6 in the electric motorcycle support device realizes the rotation function of the support device; the combination of the circular shell 61, the rotating body 63 and the ball bearing 64 constitutes a rotating mechanism, and the rotation of the rotating body 63 is realized by the cooperation of the first rotating shaft 632 and the second rotating shaft 633; ​​the mounting base 65 is fixed to the lower end of the second rotating shaft 633 and is hinged to the support leg 5, and the return force is provided by the return spring 67 to keep the support leg 5 in the initial position.

[0130] This design enables the electric motorcycle support device to rotate, allowing the entire vehicle body to rotate freely while being supported; through the structure of the rotating component 6 and the movement of the ball bearing 64, convenient turning operations and parking flexibility are achieved; this implementation method improves the handling and parking convenience of the electric motorcycle. Example 8

[0131] refer to Figure 6 As shown, the rotation assembly 6 is equipped with a recovery assembly 7.

[0132] In this embodiment, the electric motorcycle support device includes a rotating component 6 and a restoring component 7. Several possible implementations of the restoring component 7 are listed below:

[0133] Spring-type restoring assembly 7: A spring is installed in the rotating assembly 6, which connects the rotating body 63 and the fixed part, providing a restoring force. When the rotating assembly 6 rotates to a certain angle, the spring generates a restoring force, causing the rotating assembly 6 to return to its original position.

[0134] Hydraulic cylinder type recovery assembly 7: A hydraulic cylinder is installed in the rotating assembly 6. The hydraulic cylinder is connected to the control device through a hydraulic system. The control device can adjust the pressure of the hydraulic cylinder to control the rotation speed and return force of the rotating assembly 6. By controlling the change of hydraulic pressure, the recovery function of the rotating assembly 6 can be realized.

[0135] Pneumatic recovery component 7: A pneumatic cylinder is installed in the rotating component 6, and the pneumatic cylinder is connected to an air source and a control device; by adjusting the pressure of the air source and the operation of the control device, the recovery function of the rotating component 6 can be realized; by controlling the change of air pressure, the rotation speed and return force of the rotating component 6 can be adjusted.

[0136] Motor-type recovery component 7: A motor is installed in the rotating component 6 and the motor is connected to the control device; the control device can realize the recovery function of the rotating component 6 by controlling the speed and direction of the motor; by adjusting the running state of the motor, the rotating component 6 can be returned to the initial position.

[0137] The above are some possible implementations of the recovery components 7, which can be selected and used according to specific needs and designs. The function of these recovery components 7 is to provide a restoring force after the rotating component 6 has rotated to a certain angle, so that the rotating component 6 returns to its initial position and maintains the normal working state of the support device. Example 9

[0138] refer to Figure 8 As shown, the recovery component 7 includes:

[0139] A coil spring 71 is installed between the rotating body 63 and the circular housing 61.

[0140] In this embodiment, the restoration assembly 7 of the electric motorcycle support device includes a coil spring 71 installed between the rotating body 63 and the circular housing 61. The following are the implementation methods and advantages of using the coil spring 71:

[0141] Elastic restoring force: The coil spring 71 is elastic. When the rotating body 63 rotates to a certain angle, the coil spring 71 will be compressed or stretched, generating a restoring force. This restoring force can return the rotating component 6 to its original position and maintain the normal working state of the support device.

[0142] Stability and reliability: As a spring element, coil spring 71 has stable restoring characteristics; it can maintain a certain elastic force for a long time and is not easy to deform or fatigue; this makes coil spring 71 highly reliable and durable in electric motorcycle support devices.

[0143] Space saving: The coil spring 71 has a compact design and takes up little space; this is very important for electric motorcycle support devices, as motorcycles usually have limited space; the coil spring 71 can make efficient use of limited space and integrate closely with other components.

[0144] Adjustable performance: The restoring force of the coil spring 71 can be adjusted by selecting appropriate materials and wire diameters; according to the required restoring force and the characteristics of the rotating component 6, appropriate parameters of the coil spring 71 can be selected to meet the design requirements.

[0145] Economic efficiency: The coil spring 71 has a relatively low manufacturing cost and is easy to process and install; this makes the coil spring 71 an economical and practical choice that can be widely used in fields such as electric motorcycle support devices.

[0146] In summary, it is understandable that the coil spring 71, as the restoring component 7 of the electric motorcycle support device, has advantages such as elastic restoring force, stability, reliability, space saving, adjustability, and economy; it can provide appropriate restoring force to return the support device to its original position and maintain good working performance. Example 10

[0147] refer to Figures 6 to 7 As shown, limit seats 68 are respectively installed at both ends of the hinge shaft of the support leg 5, and the limit seats 68 abut against the mounting base 65.

[0148] The support leg 5 is provided with a foot support rod 51 on the side near the support assembly. The foot support rod 51 is provided with a bend 52, which forms a fulcrum against the ground. A foot pedal 53 is rotatably installed at the end of the foot support rod 51.

[0149] In this embodiment, the electric motorcycle support device is implemented as follows:

[0150] Hinged shaft and limiting seat 68: Limiting seats 68 are installed at both ends of the hinged shaft of the support leg 5; the limiting seats 68 abut against the mounting seat 65 to limit the rotation range of the support leg 5 and ensure the stability and safety of the support device.

[0151] Foot support rod 51: A foot support rod 51 is provided on the side of the support leg 5 near the support component; a bend 52 is provided on the foot support rod 51 to form a fulcrum on the ground; this bend 52 can serve as a rotation fulcrum to support the foot pedal 53.

[0152] Foot pedal 53: Foot pedal 53 is rotatably mounted on the end of foot support rod 51; foot pedal 53 is a component for the driver to step on, used to control the extension and retraction of the support leg 5; by the driver's stepping action, foot pedal 53 and foot support rod 51 rotate together, thereby operating the extension and retraction of the support leg 5.

[0153] The specific operating procedure is as follows:

[0154] When the driver needs to extend the support leg 5, he can step on the pedal 53 with his foot; since the pedal 53 is connected to the pedal support rod 51, the stepping action will cause the pedal support rod 51 and the pedal 53 to rotate together.

[0155] The rotation of the foot support 51 is transmitted to the support leg 5 through the hinge shaft, causing the support leg 5 to unfold and stand up.

[0156] When the support leg 5 is fully extended and stably supports the vehicle, the limiting seat 68 and the mounting seat 65 abut against each other, restricting further rotation of the support leg 5.

[0157] When the driver needs to retract the support leg 5, pushing the vehicle forward will return the support leg 5 to its original position. The retraction action of the support leg 5 is transmitted through the hinge shaft, bringing the support leg 5 back to its original position.

[0158] Through the above implementation, the hinge shaft, limit seat 68, foot pedal 51 and foot pedal 53 of the support leg 5 cooperate with each other to realize the convenient operation of unfolding and retracting the support leg 13; the driver can control the state of the support leg 5 by stepping on the foot pedal 53, thereby providing stable support and convenient parking function; this design also increases the convenience of use and parking safety of electric motorcycles.

[0159] The beneficial effects of the present invention are specifically reflected in the fact that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
