Description

[0001] This utility model is a divisional application of application number 2024218007466, filed on July 29, 2024, entitled "An Electric Vehicle Foot Stand". Technical Field

[0002] This utility model relates to the field of electric vehicle support structure technology, specifically to an electric vehicle kickstand and an electric vehicle. Background Technology

[0003] In related technologies, electric vehicles mainly consist of an electric vehicle kickstand and a frame. The electric vehicle kickstand mainly comprises an interconnected base structure and a connecting structure. The top of the connecting structure is rotatably connected to the frame, while the bottom of the base structure is used to support the ground. Generally, a specific type of electric vehicle can only be fitted with a kickstand of the corresponding specification. For example, when the frame is supported on the ground by the electric vehicle kickstand and tilted at a certain angle relative to the ground, the frame tilts towards the electric vehicle kickstand and is stably supported by it, thus allowing the frame to be parked stably.

[0004] However, when this specification of electric vehicle kickstand is installed on the frame of other electric vehicle models, if the base structure of the electric vehicle kickstand is too far off from the center of gravity of the frame of that electric vehicle model, causing the angle between the electric vehicle kickstand and the ground to be outside the set angle range (e.g., 30 degrees to 75 degrees), it may cause the frame to tip over in the direction of the electric vehicle kickstand, resulting in poor versatility of the electric vehicle kickstand. Utility Model Content

[0005] The problem this invention solves is how to improve the versatility of electric vehicle kickstands.

[0006] To solve the above problems, this utility model provides an electric vehicle kickstand and an electric vehicle.

[0007] In a first aspect, this utility model provides an electric vehicle kickstand, including a base structure and a connecting structure. The connecting structure includes a connecting rod structure and a connecting seat. The connecting seat is rotatably connected to the vehicle frame. The connecting rod structure is movably connected to the connecting seat. One end of the connecting rod structure away from the connecting seat is connected to the base structure. The base structure is movable relative to the connecting seat in the left-right direction of the vehicle frame via the connecting rod structure.

[0008] Optionally, the connection structure further includes a first fastener that extends along the front-rear direction of the frame and passes through the connecting seat and the connecting rod structure. The connecting rod structure is used to rotate relative to the connecting seat about the axis of the first fastener.

[0009] Optionally, when the axis of the connecting rod structure is parallel to the axis of the connecting seat, the position of the connecting rod structure is the starting position of rotation. The rotation angle of the connecting rod structure relative to the starting position of rotation in the direction away from the frame is in the range of 0 to 15 degrees, and the rotation angle of the connecting rod structure relative to the starting position of rotation in the direction closer to the frame is in the range of 0 to 5 degrees.

[0010] Optionally, the connecting seat is provided with a first toothed disc, and the connecting rod structure is provided with a second toothed disc at one end near the connecting seat. The axes of the first toothed disc and the second toothed disc are perpendicular to the extension direction of the connecting rod structure. The first toothed disc and the second toothed disc are arranged opposite to each other and mesh with each other. The first fastener passes through the center of the first toothed disc and the second toothed disc.

[0011] Optionally, the connecting rod structure includes a connecting sleeve and a second rod. The connecting sleeve is movably connected to the connecting seat, and the connecting sleeve is sleeved on the second rod. The connecting sleeve and the second rod are movably connected along the axial direction of the connecting structure, and the second rod is connected to the base structure.

[0012] Optionally, the second rod is provided with a plurality of slots spaced apart along its axial direction, the connecting sleeve is provided with a mounting hole, and the connecting structure further includes a locking structure, which is disposed at the mounting hole and is used to engage or disengage from the slots.

[0013] Optionally, the locking structure includes a button assembly and a retaining ring. The button assembly is embedded in the mounting hole, and the retaining ring is mounted on the button assembly. The retaining ring is sleeved on the second rod and is used to engage or disengage from the retaining groove under the action of the button assembly.

[0014] Optionally, the button assembly includes a button body and a spring, the spring being sleeved or embedded in the button body, and the end of the spring away from the button body abutting against the second rod; the retaining ring is mounted on the button body.

[0015] Optionally, the locking structure includes a locking bolt, and the connecting sleeve is further provided with a locking hole at a position corresponding to the slot. The locking bolt is threadedly connected to the locking hole, and the locking bolt is used to rotate within the locking hole to abut against or move away from the slot.

[0016] Optionally, the second rod has a connecting head at the end away from the connecting sleeve, the base structure is provided with a receiving groove, the connecting head is embedded in the receiving groove, and the connecting head is used to rotate within the receiving groove.

[0017] Optionally, the base structure includes a first mounting base and a second mounting base, with a first groove and a second groove respectively formed on the first mounting base and the second mounting base. The second mounting base is detachably connected to the first mounting base, and the second groove and the first groove together form the receiving groove.

[0018] Optionally, the electric vehicle kickstand also includes a wireless charging head, and the base structure also includes a base body. The base body has a receiving cavity, and the wireless charging head is disposed in the receiving cavity. At least one of the first mounting seat and the second mounting seat is disposed on the base body.

[0019] Secondly, this utility model provides an electric vehicle, including a frame and an electric vehicle kickstand as described above.

[0020] The beneficial effects of this utility model's electric vehicle kickstand and the electric vehicle itself are:

[0021] One end of the connecting rod structure, for example, the top end, is movably connected to the connecting seat, and the other end of the connecting rod structure away from the connecting seat, for example, the bottom end, is connected to the base structure. The connecting rod structure can be rotatably connected to the frame through the connecting seat, so as to realize that the electric vehicle kickstand can rotate relative to the frame to perform the retraction or lowering action.

[0022] Since one end of the connecting rod structure, such as the top end, is movably connected to the connecting seat, the base structure can move relative to the connecting seat in the left-right direction of the frame via the connecting rod structure. In other words, the base structure at the bottom of the connecting rod structure can move away from or closer to the frame in the left-right direction of the frame to change the support angle and height of the frame, thereby changing the position of the frame's center of gravity. This makes the angle between the extension line of the adjusted connecting rod structure and the ground within a set angle range (e.g., 30 degrees to 75 degrees). As a result, the base structure located at the bottom of the connecting rod structure can be closer to the vertical line where the center of gravity of the frame is located in an inclined posture, thereby ensuring parking stability for frames of different specifications and correspondingly improving the versatility of the electric vehicle kickstand.

[0035] To address the problems existing in the aforementioned related technologies, this embodiment provides an electric vehicle kickstand and an electric vehicle.

[0036] like Figure 1 As shown in the figure, an electric vehicle kickstand provided by this utility model embodiment includes a base structure 1 and a connecting structure 3. The connecting structure 3 includes a connecting rod structure 34 and a connecting seat 35. The connecting seat 35 is rotatably connected to the vehicle frame. The connecting rod structure 34 is movably connected to the connecting seat 35. The end of the connecting rod structure 34 away from the connecting seat 35 is connected to the base structure 1. The base structure 1 is used to move relative to the connecting seat 35 in the left-right direction of the vehicle frame via the connecting rod structure 34.

[0037] Specifically, the electric vehicle kickstand can be installed on the left side of the frame. The connecting structure 3 is used to adjust the relative position of the base structure 1 and the vertical line where the center of gravity of the frame is located. The end of the connecting seat 35 is rotatably connected to the frame, and one end of the connecting rod structure 34, for example, the top end, is movably connected to the connecting seat 35. In other words, the connecting rod structure 34 can move relative to the connecting seat 35, and the end of the connecting rod structure 34 away from the connecting seat 35, for example, the bottom end, is connected to the base structure 1. The connecting rod structure 34 is a component between the connecting seat 35 and the base structure 1. In short, the connecting rod structure 34 of the connecting structure 3 moves with respect to the connecting seat 35 in a certain degree of freedom, which can drive the base structure 1 at the bottom end of the connecting rod structure 34 to move away from or closer to the frame in the left and right directions.

[0038] In this embodiment, one end of the connecting rod structure 34, for example, the top end, is movably connected to the connecting seat 35, and the other end of the connecting rod structure 34 away from the connecting seat 35, for example, the bottom end, is connected to the base structure 1. The connecting rod structure 34 can be rotatably connected to the frame through the connecting seat 35, so as to realize that the electric vehicle kickstand can rotate relative to the frame to perform the retraction or lowering action.

[0039] Since one end of the connecting rod structure 34, for example the top end, is movably connected to the connecting seat 35, the base structure 1 can move relative to the connecting seat 35 in the left and right directions of the frame via the connecting rod structure 34. In other words, the base structure 1 at the bottom of the connecting rod structure 34 can move away from or closer to the frame in the left and right directions of the frame to change the support angle and height of the frame, thereby changing the position of the frame's center of gravity. This makes the angle between the extension line of the adjusted connecting rod structure 34 and the ground within a set angle range (e.g., 30 degrees to 75 degrees). This allows the base structure 1 at the bottom of the connecting rod structure 34 to be closer to the vertical line where the center of gravity of the frame is located in an inclined posture, thereby ensuring parking stability for frames of different specifications and correspondingly improving the versatility of the electric vehicle kickstand.

[0040] Optionally, combined Figure 1 As shown, the connecting structure 3 further includes a first fastener, which extends along the front-rear direction of the frame and passes through the connecting seat 35 and the connecting rod structure 34. The connecting rod structure 34 is used to rotate relative to the connecting seat 35 about the axis where the first fastener is located.

[0041] Specifically, the front-rear direction of the frame refers to the direction of travel of the electric vehicle; the first fastener can extend along the front-rear direction of the frame, and the first fastener can be horizontally installed through the connecting rod structure 34 and the connecting seat 35 to connect the connecting rod structure 34 and the connecting seat 35 together. Therefore, in this embodiment, by rotating the connecting rod structure 34 and the connecting seat 35 together, the base structure 1 can move in the left-right direction of the frame relative to the connecting seat 35 through the connecting rod structure 34.

[0042] The connecting rod structure 34 of the connecting structure 3 is used to rotate about the axis where the first fastener is located relative to the connecting seat 35 in a certain degree of freedom, thereby driving the base structure 1 at the bottom of the connecting rod structure 34 to move away from or closer to the frame in the left and right directions of the frame.

[0043] Optionally, when the axis of the connecting rod structure 34 is parallel to the axis of the connecting seat 35, the position of the connecting rod structure 34 is the starting position of rotation. The rotation angle range of the connecting rod structure 34 relative to the starting position of rotation in the direction away from the frame is 0 to 15 degrees, and the rotation angle range of the connecting rod structure 34 relative to the starting position of rotation in the direction closer to the frame is 0 to 5 degrees.

[0044] Specifically, the fact that the axis of the connecting rod structure 34 is parallel to the axis of the connecting seat 35 means that the extension direction of the connecting seat 35 is consistent with the axis of the connecting rod structure 34. In this case, one end of the connecting seat 35 along its extension direction is used to rotatably connect with the frame, and the other end is connected to the connecting rod structure 34.

[0045] When the axis of the connecting rod structure 34 is parallel to that of the connecting seat 35, the position of the connecting rod structure 34 is the starting position of the rotation of the connecting rod structure 34. After the connecting rod structure 34 rotates relative to the connecting seat 35 around the axis of the first fastener, the position of the connecting rod structure 34 is the ending position of the rotation. Since the electric vehicle kickstand is usually installed on the left side wall of the frame, the angle range of the connecting rod structure 34 rotating from the starting position toward the direction away from the frame can be 0 to 15 degrees. In other words, the maximum angle of the connecting rod structure 34 rotating to the left / outward (i.e. away from the frame) can be 15 degrees (the maximum angle between the ending position and the starting position of the rotation).

[0046] Alternatively, the connecting rod structure 34 can rotate from the starting position toward the direction closer to the frame by an angle ranging from 0 to 5 degrees. In other words, the maximum angle at which the connecting rod structure 34 rotates to the right / inward (i.e. toward the frame) can be 5 degrees (the maximum angle between the ending position and the starting position of rotation).

[0047] In this optional embodiment, when the electric vehicle kickstand is suitable for installation on the frame of electric vehicles of different models, the position of the base structure 1 can be estimated based on the vertical position of the center of gravity of the frame. Then, the connecting rod structure 34 is adjusted to rotate relative to the connecting seat 35 around the axis of the first fastener until the angle between the extension line of the connecting rod structure 34 and the ground is within the range of 30 degrees to 75 degrees. At this time, the base structure 1 is close to the vertical line of the center of gravity of the frame of that model. In other words, by rotating the connecting rod structure 34 around the axis of the first fastener relative to the connecting seat 35, the base structure at the lower end of the connecting rod structure 34 is adjusted to be close to the vertical line of the center of gravity of the frame, thereby achieving stable support for the electric vehicle of the corresponding model.

[0048] Optionally, combined Figure 2 and Figure 3 As shown, the connecting seat 35 is provided with a first toothed disc 351, and the connecting rod structure 34 is provided with a second toothed disc 341 at one end near the connecting seat 35. The axes of the first toothed disc 351 and the second toothed disc 341 are perpendicular to the extension direction of the connecting rod structure 34. The first toothed disc 351 and the second toothed disc 341 are arranged opposite to each other and mesh with each other. The first fastener passes through the center of the first toothed disc 351 and the second toothed disc 341.

[0049] Specifically, the connecting seat 35 and the connecting rod structure 34 can adopt the following structure to realize angle adjustment and position locking after angle adjustment. For example, a first toothed disc 351 is provided on the connecting seat 35, and a second toothed disc 341 is provided on the connecting rod structure 34 near the end of the connecting seat 35, such as the top end. The opposing surfaces of the first toothed disc 351 and the second toothed disc 341 have toothed portions, and the toothed portions include a plurality of protrusions arranged in a ring-shaped interval.

[0050] The first toothed disc 351 and the second toothed disc 341 are meshed and connected. The connecting seat 35 and the connecting rod structure 34 can be connected and fixed by the first fastener passing through the center of the first toothed disc 351 and the second toothed disc 341.

[0051] The first fastener may be a bolt fastener, which includes a fastening bolt and a fastening nut.

[0052] In this optional embodiment, the connecting rod structure 34 and the connecting seat 35 can be rotated and their positions locked by means of the following: for example, by loosening or removing the first fastener, separating the second toothed disc 341 of the connecting rod structure 34 from the first toothed disc 351 of the connecting seat 35, and then the connecting rod structure 34 can be rotated relative to the connecting seat 35 around the axis of the first fastener so that the angle between the extension line of the connecting rod structure 34 and the horizontal plane is within the aforementioned angle range (e.g., 30 degrees to 75 degrees). Subsequently, the second toothed disc 341 is engaged with the first toothed disc 351, and the fastening bolt of the first fastener passes through the center of the first toothed disc 351 and the second toothed disc 341, and a fastening nut is connected. At this time, the engagement of the teeth of the first toothed disc 351 and the second toothed disc 341, as well as the first fastener, can be used to lock the position of the connecting rod structure 34 and the connecting seat 35 at the current rotation angle, so as to prevent the connecting rod structure 34 from rotating relative to the connecting seat 35 during use.

[0053] In related technologies, a certain type of electric vehicle can only be matched with electric vehicle kickstands of a corresponding specification, such as length. When the electric vehicle kickstand of that specification is installed on the frame of another type of electric vehicle, if the length of the electric vehicle kickstand is too short, it may cause the frame of the electric vehicle to tip over towards the electric vehicle kickstand. If the length of the electric vehicle kickstand is too long, for example, after supporting the frame of the electric vehicle, the angle between the frame and the ground is greater than 75 degrees. In this case, the electric vehicle may tip over towards the direction without the electric vehicle kickstand when subjected to a little external force, thus resulting in poor versatility of the electric vehicle kickstand.

[0054] Optionally, combined Figure 4 As shown, the connecting rod structure 34 includes a connecting sleeve 36 and a second rod 31. The connecting sleeve 36 is movably connected to the connecting seat 35. The connecting sleeve 36 is sleeved on the second rod 31. The connecting sleeve 36 and the second rod 31 are movably connected along the axial direction of the connecting structure 3. The second rod 31 is connected to the base structure 1.

[0055] Specifically, in combination Figure 2 As shown, the connecting rod structure 34 can directly include the connecting sleeve 36 and the second rod 31; or, in combination with... Figure 4As shown, the connecting rod structure 34 includes a first rod 32 and a second rod 31. The first rod 32 includes a connecting sleeve 36 and a second gear 341. The connecting sleeve 36 is sleeved on the second rod 31, and the second gear 341 is provided at the end of the connecting sleeve 36 away from the second rod 31.

[0056] Specifically, the connecting structure 3 can be divided into two parts: a connecting sleeve 36 and a second rod 31. The connecting sleeve 36 and the second rod 31 can be arranged along the axial direction of the connecting structure 3.

[0057] The electric vehicle kickstand features a height adjustment mechanism, which is implemented via a connecting rod structure 34. This mechanism includes a connecting sleeve 36 and a second rod 31. The movable connection between the connecting sleeve 36 and the second rod 31 along the axial direction of the connecting structure 3 means that the second rod 31 can be adjusted along the axial direction of the connecting structure 3 to change its connection position with the connecting sleeve 36, thereby altering the overall length of the connecting rod structure 34. The axial dimension of the connecting rod structure 34 is its length.

[0058] Therefore, this application improves the structure of the existing foot support, that is, the second rod 31 can be adjusted along the axis of the connecting structure 3 to adjust the connection position with the connecting sleeve 36 in order to adjust the length of the entire electric vehicle foot support, so that it can be applied to electric vehicles with different center of gravity heights.

[0059] Optionally, the connecting rod structure 34 can also adjust its length and lock its position after length adjustment in the following ways, for example, by combining... Figure 4 As shown, the second rod 31 is provided with a plurality of slots 312 spaced apart along its axial direction, the connecting sleeve 36 is provided with mounting holes 321, and the connecting structure 3 further includes a locking structure 33, which is disposed at the mounting hole 321 and is used to engage or disengage from the slots 312.

[0060] Specifically, the connecting sleeve 36 can be a sleeve structure. The connecting sleeve 36 and the second rod 31 can be locked in position after length adjustment by the locking structure 33 during the relative approach or distance between them in the axial direction of the connecting rod structure 34. The inner diameter of the connecting sleeve 36 is larger than the outer diameter of the second rod 31, which is a rod-shaped structure, thus facilitating the fitting of the connecting sleeve 36 onto the second rod 31. A mounting hole 321 is formed in the circumferential sidewall of the connecting sleeve 36 so that the locking structure 33 can be installed in the mounting hole 321 in an embedded manner. Multiple slots 312 are distributed at intervals along the axial direction of the second rod 31.

[0061] The length of the connecting rod structure 34 is adjusted by the second rod 31 and the connecting sleeve 36, so that the length of the entire connecting rod structure 34 changes. Since the bottom end of the second rod 31 is connected to the base structure 1, the connecting sleeve 36 moves along the axis of the connecting rod structure 34 on the second rod 31 to move closer to or further away from the base structure 1, so that the minimum distance between the bottom end of the connecting sleeve 36 and the upper end of the base structure 1 can be 3mm and the maximum distance can be 50mm. In other words, the length adjustment range of the entire electric vehicle kickstand is 0-47mm.

[0062] In this optional embodiment, when it is necessary to adjust the length of the connecting rod structure 34, the locking structure 33 can be operated to disengage the locking structure 33 from the slot 312 on the second rod 31. At this time, the locking structure 33 no longer obstructs the axial movement of the second rod 31 relative to the connecting sleeve 36. When the second rod 31 moves axially relative to the connecting sleeve 36 to make the length of the connecting rod structure 34 meet the on-site requirements, the locking structure 33 can be operated to make it engage with the slot 312 on the second rod 31. At this time, the locking structure 33 connects the second rod 31 and the connecting sleeve 36 into an integral structure, thereby locking the position of the second rod 31 within the connecting sleeve 36. In other words, the position lock of the connecting rod structure 34 after length adjustment is achieved.

[0063] Optionally, combined Figure 4 As shown, the locking structure 33 includes a button assembly 331 and a retaining ring 332. The button assembly 331 is embedded in the mounting hole 321, and the retaining ring 332 is mounted on the button assembly 331. The retaining ring 332 is sleeved on the second rod 31, and the retaining ring 332 is used to engage or disengage from the retaining groove 312 under the action of the button assembly 331.

[0064] Specifically, the size of the mounting hole 321 is slightly larger than that of the button assembly 331, so as to facilitate the smooth installation of the button assembly 331 into the mounting hole 321 of the first rod 32. One end of the retaining ring 332 can be installed on the button assembly 331, and the other part of the retaining ring 332 can be sleeved on the second rod 31. By operating the button assembly 331, the retaining ring 332 can be engaged with or disengaged from the retaining groove 312.

[0065] The force refers to the pushing force applied by the rider to the button assembly 331 when the length of the connecting structure needs to be adjusted, so as to disengage the retaining ring 332 from the slot 312; or, after the length of the connecting structure is adjusted, the elastic restoring force of the spring 3312 in the button assembly 331 so as to re-engage the retaining ring into the slot 312.

[0066] In this optional embodiment, when the length of the connecting structure needs to be adjusted, the button assembly 331 is pressed, allowing it to move inward within the mounting hole 321 towards the inside of the connecting sleeve 36. At this time, the retaining ring 332 moves away from the button assembly 331 into the first rod 32 (or connecting sleeve 36) under the force of the button assembly 331, such as a pushing or pressing force. This allows the retaining ring 332 to disengage from the retaining groove 312 of the second rod 31, freeing the second rod 31 from the restriction of the retaining ring 332 and enabling it to move axially within the connecting sleeve 36 to adjust the connecting rod structure 34. The length of the connecting rod structure 34 is adjusted; after the length of the connecting rod structure 34 is adjusted, the button assembly 331 is released so that the button assembly 331 moves outward in the mounting hole 321 to reset when the external force is lost. At this time, the retaining ring 332 can be locked again in the slot 312 on the second rod 31 under the force of the button assembly 331, such as the elastic restoring force. Through the cooperation between the button assembly 331 embedded in the mounting hole 321 of the connecting sleeve 36 and the retaining ring 332, the position of the second rod 31 in the first rod 32 is locked. In other words, the position of the connecting rod structure 34 is locked after the length is adjusted.

[0067] Alternatively, the button component 331 can be adopted in the following manner, for example, by combining Figure 4 As shown, the button assembly 331 includes a button body 3311 and a spring 3312. The spring 3312 is sleeved or embedded in the button body 3311. One end of the spring 3312 away from the button body 3311 abuts against the second rod 31. The retaining ring 332 is installed on the button body 3311.

[0068] For example, the end of the spring 3312 is fixedly installed on the button body 3311 by means of adhesive, snap-fit, riveting, etc. The spring 3312 can be a compression spring.

[0069] Optionally, combined Figure 4 As shown, the locking structure 33 includes a locking bolt, and the connecting sleeve 36 is also provided with a locking hole 322 at a position corresponding to the slot 312. The locking bolt is threadedly connected to the locking hole 322, and the locking bolt is used to rotate within the locking hole 322 to abut against or move away from the slot 312.

[0070] Specifically, when it is necessary to adjust the length of the connecting structure 3, loosen the locking bolt in the locking hole 322 so that the locking bolt is away from the slot 312. At this time, the locking bolt will not hinder the up and down movement of the second rod 31 in the connecting sleeve 36 (or the first rod 32). After the length of the connecting structure 3 is adjusted, tighten the locking bolt in the locking hole 322 until the locking bolt abuts against the slot 312 of the second rod 31. Thus, the position of the second rod 31 in the connecting sleeve 36 can also be locked by the locking bolt.

[0071] The locking bolt in the locking structure 33 can be used simultaneously with the button assembly 331 and the retaining ring 332, or one of them can be used at will, depending on the rider's needs.

[0072] In one related technology, a two-wheeled shared electric vehicle can be charged via a kickstand. The kickstand mainly includes a base, a support rod, and a wireless charging head. The top of the support rod can be connected to the frame of the electric vehicle, and the bottom of the support rod is fixedly connected to the base. The wireless charging head is installed inside the base. Charging piles are installed on the ground in the fixed parking area, and the charging piles have guide grooves that match and plug into the wireless charging head. When the electric vehicle is parked in the fixed parking area for charging, the wireless charging head of the electric vehicle's kickstand needs to be plugged into the guide groove of the charging pile so that the battery of the electric vehicle can be charged through the charging pile and the wireless charging head.

[0073] However, in actual fixed parking areas, uneven ground or mismatches between the kickstands of different electric vehicle models and the positions of the installed charging piles can prevent the wireless charging head inside the kickstand from being accurately inserted into the guide slot of the charging pile, thus affecting the charging operation of the electric vehicle.

[0074] Optionally, combined Figure 4 As shown, the second rod 31 has a connecting head 311 at the end away from the connecting sleeve 36. The base structure 1 is provided with a receiving groove 11. The connecting head 311 is embedded in the receiving groove 11 and is used to rotate within the receiving groove 11.

[0075] Specifically, the electric vehicle kickstand also has a leveling mechanism, which includes a connecting structure 3 and a base structure 1. The end of the second rod 31 away from the first rod 32, for example, the bottom end, has the connecting head 311. The connecting head 311 at the bottom end of the second rod 31 can be embedded in the receiving groove 11 of the base structure 1 and is used to rotate within the receiving groove 11. The relative rotation of the connecting structure 3 and the base structure 1 is used to achieve leveling of the base structure 1.

[0076] The connecting head 311 can be at least one of the following: a spherical structure, a non-complete spherical structure, or a horizontally arranged cylindrical structure. A non-complete spherical structure refers to half of a spherical structure or a structure with a volume greater than half a spherical structure. If the connecting head 311 is a spherical structure or a non-complete spherical structure, then the receiving groove 11 is a spherical groove structure with a corresponding shape. In this case, the connecting head 311 and the receiving groove 11 are connected by a ball joint.

[0077] Optionally, the base structure 1 includes a first mounting base 12 and a second mounting base 13. A first groove 121 and a second groove 131 are respectively formed on the first mounting base 12 and the second mounting base 13. The second mounting base 13 is detachably connected to the first mounting base 12. The second groove 131 and the first groove 121 together form the receiving groove 11.

[0078] Specifically, the base structure 1 can be formed into the receiving groove 11 in the following manner. For example, the base structure 1 can be divided into two parts, namely a first mounting base 12 and a second mounting base 13. A first groove 121 is opened on the first mounting base 12, and a second groove 131 is opened on the second mounting base 13. The inner diameters of the first groove 121 and the second groove 131 can be equal or unequal.

[0079] Furthermore, the base structure 1, which is assembled from the first mounting base 12 and the second mounting base 13, can rotate relative to the connecting head 311 of the connecting structure 3 with the extension direction of the connecting structure 3 as the initial position. The base structure 1 can rotate omnidirectionally relative to the connecting structure 3 in any direction. If the size of the receiving groove 11 is slightly larger than the size of the connecting head 311, the rotation angle range of the base structure 1 relative to the connecting structure 3 can be 0 degrees to 10 degrees.

[0080] The second mounting base 13 can be detachably connected to the first mounting base 12 in the following ways, such as by bolt fasteners, snap-fit ​​fasteners, or clamp fasteners. Taking the bolt fastener method as an example, for instance, the number of bolted fasteners is at least two, multiple through holes are provided on the first mounting base 12, and multiple threaded holes are provided on the second mounting base 13. The number and position of the through holes match the number and position of the threaded holes. The bolt fasteners pass through the through holes of the first mounting base 12 and connect to the threaded holes of the second mounting base 13 to achieve a detachable connection between the first mounting base 12 and the second mounting base 13.

[0081] In this optional embodiment, since the first mounting base 12 and the second mounting base 13 are detachably connected, when the connecting head 311 at the bottom of the connecting structure 3 is assembled with the receiving groove 11 of the base structure 1, the first mounting base 12 and the second mounting base 13 are separated. Then, the connecting head 311 of the connecting structure 3 is embedded in the second groove 131 of the second mounting base 13, and then the first mounting base 12 is fastened to the second mounting base 13, so that the first groove 121 and the second groove 131 surround and form the receiving groove 11 fitted on the connecting head 311. When it is necessary to maintain the connection between the base structure 1 and the connecting structure 3, it is only necessary to separate the first mounting base 12 and the second mounting base 13, and the connecting head 311 can be taken out from the receiving groove 11 of the base structure 1, thereby improving the convenience of disassembling and assembling the base structure 1 and the connecting structure 3.

[0082] Optionally, combined Figure 7 As shown, the electric vehicle kickstand also includes a wireless charging head 2, and the base structure 1 also includes a base body 14. The base body 14 has a receiving cavity, and the wireless charging head 2 is disposed in the receiving cavity. At least one of the first mounting seat 12 and the second mounting seat 13 is disposed on the base body 14.

[0083] Specifically, "at least one of the first mounting base 12 and the second mounting base 13 is disposed on the base body 14" means that either the first mounting base 12 or the second mounting base 13 is disposed on the base body 14, or both the first mounting base 12 and the second mounting base 13 are disposed on the base body 14.

[0084] See Figure 6 and Figure 7 As shown, the second mounting base 13 and the first mounting base 12 can each be a semi-cylindrical structure. Since the extension direction of the electric vehicle kickstand is set at an angle to the ground when it supports the ground, the axis of the second mounting base 13 is set at an acute or obtuse angle to the surface of the base body 14. This allows the base body 14 to better fit the ground under the action of the receiving groove 11 formed by the first mounting base 12 and the second mounting base 13 and the connecting head 311 of the connecting structure 3 rotating.

[0085] An accommodating cavity is provided inside the base body 14 to facilitate the installation of the wireless charging head 2 inside the accommodating cavity.

[0086] The base structure 1 is used to support the ground. The base structure 1 can be inserted into the guide groove of the charging pile in the following way: for example, the bottom of the base structure 1 is provided with an insertion protrusion, and the base structure 1 can be inserted into the guide groove of the charging pile through the insertion protrusion.

[0087] In this optional embodiment, since the wireless charging head 2 is disposed in the accommodating cavity, the base body 14 of the base structure 1 provides safety protection for the wireless charging head 2, so as to prevent the wireless charging head from being exposed to the environment and damaged by collisions with other external objects.

[0088] This application improves the structure of the existing foot support by allowing the second rod 31 in the height adjustment mechanism to move axially along the connecting rod structure 34 and the connecting sleeve 36, thereby adjusting the length of the entire electric vehicle foot support and adjusting the center of gravity height of the frame in the parked state. This makes it suitable for electric vehicles with different center of gravity heights. Furthermore, the connecting head 311, located at the end of the second rod 31 away from the first rod 32 (or connecting sleeve 36) in the leveling mechanism, can rotate within the receiving groove 11 of the base structure 1 to adjust the tilt angle of the base structure 1 relative to the horizontal plane, thus enabling the adjustable tilt angle base structure 1 to be suitable for various electric vehicle models. On various uneven ground surfaces, the base structure 1 is leveled to ensure better alignment between the wireless charging head and the guide groove of the charging pile. This not only provides stable support for vehicles with different center of gravity heights, but also increases the angle adjustment range of the base structure 1 relative to the horizontal plane, as the base structure 1 can rotate relative to the connecting head 311 of the second rod 31. This improves the alignment accuracy between the wireless charging head and the guide groove of the charging pile, as well as the wireless charging efficiency of the charging pile for the electric vehicle's battery. Consequently, it is suitable for various electric vehicles that can be wirelessly charged.

[0089] This utility model provides an electric vehicle, including a frame and an electric vehicle kickstand as described above.

[0090] Specifically, the part of the frame that connects to the electric vehicle kickstand is the fixing part. Therefore, the end of the electric vehicle kickstand connection structure away from the base structure 1, such as the top, is connected to the fixing part of the frame. The electric vehicle can be either one that cannot be wirelessly charged or one that can be wirelessly charged.

[0091] The beneficial effects of the electric vehicle in this embodiment compared to the prior art are the same as those of the electric vehicle kickstand described above, and will not be repeated here.

[0092] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
