[0037] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0038] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0041] like Figures 3 to 6 As shown, the present invention provides a single support structure 1, comprising a single support tube 100, a single support rod 200, an elastic member 300, and a limiting member 400. The single support tube 100 has one axial end connected to the vehicle body; the single support rod 200 has one axial end slidably connected to the other axial end of the single support tube 100, and the other axial end of the single support rod 200 is used to abut against a supporting surface; the elastic member 300 ensures that the single support rod 200 always has a tendency to move away from the vehicle body along the axial direction of the single support tube 100; and the limiting member 400 is relatively fixed to the single support tube 100 and can limit the distance that the single support rod 200 can move away from the vehicle body along the axial direction of the single support tube 100.

[0042] Thus, when the single-strut structure 1 is used to support a vehicle body and a supporting surface, one end of the single-strut rod 200 contacts the supporting surface, and the single-strut rod 200 and the single-strut tube 100 are squeezed together by the vehicle body and the supporting surface. The elastic member 300 undergoes elastic deformation when subjected to force. Firstly, when the elastic member 300 acts on the single-strut rod 200, the single-strut rod 200 always contacts the ground, maintaining stability. Secondly, the elastic member 300 balances the pressure applied by the vehicle body through its own elastic deformation. When the load on the vehicle body changes, the elastic member 300 can adaptively adjust its deformation, allowing the vehicle body to always maintain a certain tilt angle to the ground, thereby maintaining the stability of the vehicle body.

[0043] Specifically, when the vehicle body is equipped with a large battery 21, its large mass causes the vehicle body to sink. When the axis of the wheel 3 is at a 90-degree angle to the vertical, the height of the large battery 21 above the ground is H1. When the vehicle body tilts and is supported by the single-strut structure 1, the deformation of the elastic member 300 is d1. The axial extension of the single-strut rod 200 and the single-strut tube 100 is L1. The angle between the axis of the wheel 3 and the vertical is α. When the vehicle body is equipped with a small battery 22, the mass of the small battery 22 is less than that of the large battery 21. When the axis of the wheel 3 is at a 90-degree angle to the vertical, the height of the small battery 22 above the ground is H2, satisfying H2>H1. When the vehicle body tilts and is supported by the single-strut structure 1, the corresponding deformation of the elastic member 300 is d2, satisfying d2<d1. The axial extension of the single-strut rod 200 and the single-strut tube 100 is L2, satisfying L2>L1. The angle between the axis of the wheel 3 and the vertical is β. As can be seen, when the battery mass is small, its height above the ground is high, and the extended length of the single support tube 100 and the single support rod 200 is long. When the battery mass is small, its height above the ground is low, and the extended length of the single support tube 100 and the single support rod 200 is short. By changing the deformation of the elastic member 300 to adapt to the change in height above the ground caused by the change in battery mass, α and β are always close, thereby maintaining the stability of the vehicle body.

[0044] Optionally, the single support tube 100 is parallel to the single support rod 200 , and the single support rod 200 is slidably inserted into the single support tube 100 .

[0045] For example, the single support tube 100 has a mounting hole along its axial direction, and the single support rod 200 is inserted into the single support tube 100 and can slide axially relative to the single support tube 100. In this way, the mounting hole in the single support tube 100 forms a guide rail, and the single support rod 200 is inserted into the single support tube 100, which can limit the relative movement of the single support tube 100 and the single support rod 200 except in the axial direction, and standardize the motion trajectory of the relative movement.

[0046] Optionally, the elastic member 300 is a spring placed in the single support tube 100 , and in the axial direction of the single support tube 100 , the elastic member 300 is sandwiched between the single support tube 100 and the single support rod 200 .

[0047] For example, in this embodiment, the elastic member 300 is positioned within the mounting hole of the single support tube 100. A support platform is provided axially within the mounting hole. One active end of the elastic member 300 abuts the support platform, while the other active end abuts the single support rod 200. When an external force is applied, the single support rod 200 extends deeper into the single support tube 100, squeezing the elastic member 300. The elastic member 300 counteracts the external force through its own elastic deformation. When the external force is removed, the elastic member 300 recovers its deformation, allowing the single support rod 200 to extend out of the single support tube 100.

[0048] In other embodiments, one of the active ends of the elastic member 300 is connected to the open end of the mounting hole, and the other active end is connected to the single support rod 200. Under the action of external force, when the single support rod 200 penetrates into the single support tube 100, the elastic member 300 is stretched. When the external force is removed, the elastic member 300 recovers its deformation, causing the single support rod 200 to extend out of the single support tube 100.

[0049] In other embodiments, the elastic member 300 is installed outside the single support tube 100, the outer wall of the single support tube 100 is protruded with a first support column, and the outer wall of the single support rod 200 is protruded with a second support column, and the two active ends of the elastic member 300 are respectively connected to the first support column or the second support column.

[0050] Optionally, the limit member 400 is a shaft sleeve, which is coaxially fixed to one axial end of the single support tube 100. The limit member 400 is slidably sleeved outside the single support rod 200. The single support rod 200 includes a limit portion 210. The limit portion 210 passes through the limit member 400 and abuts against the elastic member 300. The minimum inner diameter of the limit member 400 is smaller than the maximum radial dimension of the limit portion 210.

[0051] Illustratively, the limiting member 400 is fixed to the single support tube 100 by welding.

[0052] Optionally, the limiting member 400 is provided with an internal thread structure, and the limiting portion 210 of the single support rod 200 is provided with an external thread structure. The limiting portion 210 can be threadedly connected to the limiting member 400. After the limiting portion 210 passes through the limiting member 400, the internal thread structure and the external thread structure can abut along the axial direction of the single support tube 100.

[0053] Exemplarily, the single strut 200 includes a limiting portion 210 and an optical axis portion 220. The limiting portion 210 and the optical axis portion 220 are fixed along the axial direction of the single strut 200. The maximum extension length of the optical axis portion 220 is achieved by rotating the single strut 200 around the axis so that the limiting portion 210 of the single strut 200 is threadedly connected with the limiting member 400 and continues to be fed until the limiting portion 210 of the single strut 200 passes through the limiting member 400. The limiting member 400 is slidably sleeved on the optical axis portion 220 of the single strut 200. The external thread structure of the limiting portion 210 of the single strut 200 and the internal thread structure of the limiting member 400 can abut along the axial direction of the single strut tube 100, thereby limiting the maximum extension length of the single strut 200 relative to the single strut tube 100 in the axial direction.

[0054] Optionally, the single support structure 1 further includes a single support head 500 , which is fixed to the axial end face of the single support tube 100 facing away from the single support rod 200 , and is used for being hinged to the vehicle body.

[0055] Exemplarily, the single support head 500 is fixed to the single support tube 100 by welding.

[0056] Optionally, the single support structure 1 further includes a foot 600 and a ball head assembly 700. The axial end of the single support rod 200 facing away from the single support tube 100 is connected to the foot 600 via the ball head assembly 700. In this way, the foot 600 and the single support rod 200 have a relatively high degree of freedom, so that the foot 600 can always be in contact with the ground.

[0057] Optionally, the ball head assembly 700 includes a ball head screw 710 and a ball head seat 720, the ball head 711 of the ball head screw 710 is installed on the ball head seat 720, the ball head seat 720 is fixed to the single support rod 200, and the threaded portion 712 of the ball head screw 710 is threadedly connected to the base 600.

[0058] Exemplarily, the ball head seat 720 includes a ball head base and a ball head top cap. During assembly, the threaded portion 712 of the ball head screw 710 passes through the ball head base and is threadedly connected to the base foot 600. The ball head top cap and the ball head base are fixed to the ball head 711 of the ball head screw 710 to form a package. A threaded hole is provided on the axial end face of the single support rod 200 facing away from the single support tube 100. The ball head seat 720 is inserted into the threaded hole and is threadedly connected to the single support rod 200.

[0059] Optionally, the single support structure 1 further includes a foot lever 800, which is mounted on the stopper 400 or the single support tube 100. Exemplarily, the foot lever 800 is welded to the stopper 400 and is perpendicular to the single support tube 100. The driver can use the foot lever 800 to drive the single support tube 100 to rotate relative to the vehicle body.

[0060] An electric motorcycle is also provided, comprising a battery and the above-mentioned single-support structure 1, wherein the battery is fixed to the vehicle body, and the single-support tube 100 is hinged to the battery.

Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
