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, a certain type of electric vehicle can usually 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 electric vehicle kickstands.

[0018] Secondly, this utility model provides an electric vehicle, including a frame and an electric vehicle kickstand as described above.

[0019] The beneficial effects of this utility model's electric vehicle kickstand and the electric vehicle itself are:

[0020] The connection structure includes a first rod and a second rod arranged along its own axial direction. One end of the first rod, such as the top end, can be rotatably connected to the frame.

[0021] The base structure is used to support the electric vehicle on the ground when it is parked, and the connecting structure is used to adjust the center of gravity height of the electric vehicle frame. Specifically, when encountering an uneven surface, such as when the ground position of the electric vehicle kickstand is higher or lower than the ground position of the electric vehicle wheels, the connection position of the second rod and the first rod can be adjusted manually along the axis of the connecting structure to adjust the length of the entire electric vehicle kickstand, including the connecting structure, so as to adjust the tilt angle of the electric vehicle frame relative to the ground. This adjusts the center of gravity height of the frame when parked, making it suitable for electric vehicles with different center of gravity heights, thereby improving the versatility of the electric vehicle kickstand.

[0022] For example, if the center of gravity of the frame of different models is high, the length of the entire connecting structure can be increased accordingly. Conversely, if the center of gravity of the frame of different models is low, the length of the entire connecting structure can be reduced accordingly. This allows the electric vehicle kickstand to stably support the frame when it is suitable for different models of electric vehicles. Attached Figure Description

It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0031] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] To address the problems existing in the aforementioned related technologies, this embodiment provides an electric vehicle kickstand and an electric vehicle.

[0033] like Figure 1As shown in the figure, an electric vehicle kickstand provided by this utility model embodiment includes a base structure 1 and a connecting structure. The connecting structure includes a first rod 32 and a second rod 31. The first rod 32 and the second rod 31 are arranged along the axial direction of the connecting structure, and the first rod 32 and the second rod 31 are movably connected along the axial direction of the connecting structure. One end of the first rod 32 is used to connect to the vehicle frame, and the end of the second rod 31 away from the first rod 32 is connected to the base structure 1.

[0034] Specifically, the electric vehicle kickstand has a height adjustment mechanism, which can be implemented through a connecting structure. The height adjustment mechanism includes a first rod 32 and a second rod 31, which can be arranged axially along the connecting structure. One end of the first rod 32, for example, its top, can be rotatably connected to the vehicle frame, while the first rod 32 and the second rod 31 are movably connected. The end of the second rod 31 away from the first rod 32 is connected to the base structure 1.

[0035] The phrase "the first member 32 and the second member 31 are movably connected along the axial direction of the connecting structure" means that the connection position of the second member 31 with the first member 32 can be adjusted along the axial direction of the connecting structure to change the length of the entire connecting structure. The dimension of the connecting structure along its own axial direction is the length of the connecting structure.

[0036] In this embodiment, the connection structure includes a first rod and a second rod arranged along its own axial direction. One end of the first rod, such as the top end, can be rotatably connected to the frame. The end of the second rod away from the first rod, such as the bottom end, is connected to the base structure, so that the first rod of the electric vehicle kickstand rotates relative to the frame to perform a retracting or lowering action.

[0037] Specifically, the base structure is used to support the electric vehicle on the ground when it is parked. When encountering an uneven surface, such as when the ground position of the electric vehicle kickstand is higher or lower than the ground position of the electric vehicle wheels, the connection position of the second rod and the first rod can be adjusted manually along the axis of the connecting structure to adjust the length of the entire electric vehicle kickstand, including the connecting structure, so as to adjust the tilt angle of the electric vehicle frame relative to the ground. This adjusts the center of gravity height of the frame when parked, making it suitable for electric vehicles with different center of gravity heights, thereby improving the versatility of the electric vehicle kickstand.

[0038] For example, if the center of gravity of the frame of different models is high, the length of the entire connecting structure can be increased accordingly. Conversely, if the center of gravity of the frame of different models is low, the length of the entire connecting structure can be reduced accordingly. This allows the electric vehicle kickstand to stably support the frame when it is suitable for different models of electric vehicles.

[0039] Optionally, the connection structure further includes a locking structure 33, through which the first rod 32 and the second rod 31 are connected. The locking structure 33 is used to lock the position of the second rod 31 and the first rod 32 after the length of the second rod 31 and the first rod 32 in the axial direction of the connection structure is adjusted.

[0040] Specifically, the second rod 31 can be adjusted along the axial direction of the connecting structure to connect with the first rod 32 to adjust the length of the entire electric vehicle kickstand, thus making it suitable for electric vehicles with different center of gravity heights. The locking structure 33 is used to lock the position of the connecting structure after the length adjustment.

[0041] In this optional embodiment, after the lengths of the first rod 32 and the second rod 31 in the connecting structure are adjusted in the axial direction, the relative positions of the first rod 32 and the second rod 31 after the length adjustment can be locked by a locking structure. This can prevent the force applied by the frame to the electric vehicle's kickstand when the electric vehicle is parked from causing the second rod 31 to move relative to the first rod 32 along the axial direction of the connecting structure, thereby ensuring the stability of parking the electric vehicle.

[0042] The first rod 32 and the second rod 31 can achieve position locking of the connecting structure in its axial direction through different locking structures. For example, the first rod 32 and the second rod 31 are threadedly connected. Specifically, the first rod 32 is a cylindrical structure, while the second rod is a cylindrical or tubular structure. The inner diameter of the first rod 32 is larger than the outer diameter of the second rod 31. The first rod 32 is sleeved on the second rod 31. The inner wall of the first rod 32 has an internal thread, and the outer wall of the second rod 31 has an external thread. The internal thread of the first rod 32 and the external thread of the second rod 31 are threadedly connected. The second rod 31 can be rotated relative to the first rod 32 along the axial direction of the connecting structure to adjust the length of the connecting structure. In this embodiment, the internal thread of the first rod 32 and the external thread of the second rod 31 constitute the aforementioned locking structure.

[0043] Optionally, the first rod 32 and the second rod 31 are slidably connected, and the second rod 31 is used to slide relative to the first rod 32 along the axial direction of the connection structure.

[0044] Specifically, the sliding connection between the first member 32 and the second member 31 means that when the length of the connecting structure is adjusted, the second member 31 can slide relative to the first member 32 along the axial direction of the connecting structure to achieve the length adjustment of the entire connecting structure; after the length adjustment, the locking structure 33 can be connected to the first member 32 and the second member 31 to achieve the position locking of the connecting structure after the length adjustment.

[0045] The first rod 32 and the second rod 31 can be slidably connected in the following ways. For example, in the first case, the locking structure can be a bolt fastener. The first rod 32 and the second rod 31 are movably connected by the bolt fastener. Specifically, the first rod 32 and the second rod are both cylindrical structures, and the inner diameter of the first rod 32 is larger than the outer diameter of the second rod 31. The first rod 32 is sleeved on the second rod 31. The first rod 32 has first through holes spaced apart along its own axial direction, and the second rod 31 has second through holes spaced apart along its own axial direction. After the first rod 32 is sleeved on the second rod 31, by adjusting the second rod 31 relative to the first rod 32 to move along the axial direction of the connecting structure, after adjusting to a suitable length, the bolt fastener can be inserted through the first through hole of the first rod 32 and the second through hole of the second rod 31 to lock the position of the connecting structure after length adjustment.

[0046] The locking structure 33 can lock the position of the connecting structure after the length is adjusted in the following way: Specifically, the locking structure 33 can be a bolt fastener. The first rod 32 is provided with a plurality of first through holes spaced apart along its own axial direction, and the second rod 31 is provided with a plurality of second through holes spaced apart along its own axial direction. By adjusting the second rod 31 to move relative to the first rod 32 along the axial direction of the connecting structure, after adjusting to a suitable length, the bolt fastener can be inserted through the first through holes of the first rod 32 and the second through holes of the second rod 31 to lock the position of the connecting structure after the length is adjusted.

[0047] Alternatively, the connection structure can also adjust its length and lock its position after length adjustment in the following ways, for example, by combining... Figure 2 As shown, the first rod 32 is a sleeve structure, the second rod 31 is a support rod, the second rod 31 is sleeved on the first rod 32, the first rod 32 is provided with a mounting hole 321, the second rod 31 is provided with a plurality of slots 312 distributed at intervals along its axial direction, the locking structure 33 is provided at the mounting hole 321, and the locking structure 33 is used to engage or disengage from the slots 312.

[0048] Specifically, the second rod 31 and the first rod 32 can be locked in position after length adjustment by the locking structure 33 during the process of relatively approaching or relatively moving away in the axial direction of the connecting structure; the inner diameter of the sleeve structure is larger than the outer diameter of the second rod 31, which is a rod-shaped structure, thereby facilitating the first rod 32 to be sleeved on the second rod 31. A mounting hole 321 is opened in the circumferential sidewall of the first rod 32 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.

[0049] The length of the connecting structure is adjusted by the second rod 31 and the first rod 32, so that the length of the entire connecting structure changes. Since the bottom end of the second rod 31 is connected to the base structure 1, the first rod 32 moves along the axis of the connecting structure on the second rod 31 to move closer to or away from the base structure 1, so that the distance between the bottom end of the first rod 32 and the top end of the base structure 1 can be a minimum of 3mm and a maximum of 50mm. In other words, the length adjustment range of the entire electric vehicle kickstand is 0-47mm.

[0050] In this optional embodiment, when it is necessary to adjust the length of the connecting structure, 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 first rod 32. When the second rod 31 moves axially relative to the first rod 32 to make the length of the connecting structure 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 first rod 32 into a single structure, thereby locking the position of the second rod 31 within the first rod 32. In other words, it achieves position locking after the length of the connecting structure is adjusted.

[0051] Optionally, combined Figure 2 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.

[0052] 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.

[0053] 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.

[0054] In this optional embodiment, when the length of the connecting structure needs to be adjusted, the button assembly 331 is pressed so that it can move inward toward the first rod 32 within the mounting hole 321. At this time, the retaining ring 332 can move away from the button assembly 331 inward toward the first rod 32 under the force of the button assembly 331, such as a pushing force or a pressing force. This allows the retaining ring 332 to disengage from the retaining groove 312 of the second rod 31, so that the second rod 31 is no longer restricted by the retaining ring 332 and can move axially within the first rod 32 to adjust the length of the connecting structure. When the length of the connecting structure is adjusted, the button assembly 331 is released so that it moves outward in the mounting hole 321 to reset when no external force is applied. At this time, the retaining ring 332 can be engaged 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 first rod 32 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 structure is locked after the length is adjusted.

[0055] Optionally, combined Figure 2 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.

[0056] Specifically, the retaining ring 332 can be installed on the button body 3311 in the following way: for example, the button body 3311 is provided with a snap-fit ​​hole, the retaining ring 332 is a U-shaped ring, and the open end of the retaining ring 332 is snapped into the snap-fit ​​hole, so as to realize the retaining ring 332 being installed on the button body 3311 in a snap-fit ​​manner.

[0057] The spring 3312 can be sleeved or embedded in the button body 3311 in the following ways: For example, if the end of the button body 3311 facing the spring 3312 has a rod-shaped structure, and the inner diameter of the spring 3312 is larger than the outer diameter of the rod-shaped structure, then a part of the spring 3312 can be fixedly sleeved outside the rod-shaped structure of the button body 3311, and the other part of the spring 3312 protrudes from the button body 3311 and is used to abut against the second rod 31. Alternatively, if the end of the button body 3311 facing the spring 3312 has a circular groove, and the outer diameter of the spring 3312 is smaller than the inner diameter of the circular groove, then a part of the spring 3312 can be fixedly embedded in the circular groove of the button body 3311, and the other part of the spring 3312 protrudes from the button body 3311 and is used to abut against the second rod 31.

[0058] Alternatively, the end of the spring 3312 facing the button body 3311 can be fixedly mounted to the button body 3311 in the following ways: for example, the end of the spring 3312 can be fixedly mounted to the button body 3311 by means of adhesive, snap-fit, riveting, etc. The spring 3312 can be a compression spring.

[0059] In this optional embodiment, when the length of the connecting structure needs to be adjusted, the rider applies a pushing force to the button body 3311. The button body 3311 then transmits this pushing force to the spring 3312, which is compressed. Since the retaining ring 332 is engaged with the button body 3311, the button body 3311, located within the mounting hole 321 of the first rod 32, moves the retaining ring 332 inwards into the mounting hole 321 under the action of this pushing force. This causes the retaining ring 332 to disengage from the retaining groove 312. At this point, the retaining ring 332 no longer obstructs the up-and-down movement of the second rod 31 within the first rod 32, thus allowing the operation of the second rod 31. The second rod 31 moves up and down along the axial direction of the connecting structure within the first rod 32 to adjust the length of the connecting structure. After the length of the connecting structure is adjusted, the rider releases the button body 3311. At this time, the button body 3311 loses the rider's pressing force. After losing the rider's pushing force, the spring 3312 uses its own elastic restoring force to push the button body 3311 outward from the mounting hole 321. During the outward movement of the button body 3311 within the mounting hole 321, it drives the retaining ring 332 to move horizontally until it is locked into the slot 312 of the second rod 31 again, thereby achieving position locking after the length of the connecting structure is adjusted.

[0060] Optionally, combined Figure 2 As shown, the retaining ring 332 includes a first side rod portion and two oppositely arranged second side rod portions. The first side rod portion is connected to one end of the two second side rod portions, and the other ends of the two second side rod portions form an open end of the retaining ring 332. The open end of the retaining ring 332 is engaged with the button assembly 331.

[0061] Specifically, the two ends of the first side rod are respectively connected to the corresponding second side rods and can be constructed into an integrated retaining ring 332 in the shape of a U-shaped ring, thereby ensuring the mechanical strength of the retaining ring 332; the ends of the two second side rods away from the first side rod can serve as the open end of the retaining ring 332.

[0062] In this optional embodiment, the button assembly 331 includes a button body 3311, which has a snap-fit ​​hole. The snap ring 332 is a U-shaped ring, and the open end of the snap ring 332 snaps into the snap-fit ​​hole of the button body 3311, so that the snap ring 332 can be quickly installed on the button body 3311 by snap-fit, thereby improving the snap-fit ​​convenience between the snap ring 332 and the button assembly 331.

[0063] Optionally, combined Figure 2 and Figure 3 As shown, the inner wall of the first rod 32 is provided with a guide groove 323 at the position corresponding to the second side rod of the retaining ring 332. The second side rod of the retaining ring 332 is embedded in the guide groove 323, and the second side rod of the retaining ring 332 is used to move linearly along the guide groove 323.

[0064] Specifically, the inner wall of the first rod 32 is provided with a guide groove 323, which can extend along the moving direction of the button assembly 331 in the mounting hole 321; since the retaining ring 332 includes two second side rods, two guide grooves 323 are opened on the inner wall of the first rod 32, and each second side rod can be located in the corresponding guide groove 323.

[0065] In this optional embodiment, the guide groove 323 is located on the inner wall of the mounting hole 321. Since the two second side rods of the U-shaped retaining ring 332 are respectively embedded in the guide groove 323, the rider can apply a pushing force to the button assembly 331 when the length of the connecting structure needs to be adjusted, or release the button assembly 331 after the length of the connecting structure is adjusted. At this time, the button assembly 331 in the mounting hole 321 will drive the second side rod of the retaining ring 332 to slide in or out of the guide groove 323 along the extension direction of the guide groove 323. Therefore, the second side rod of the retaining ring 332 sliding in the guide groove 323 can ensure that the button assembly 331 moves linearly in a directional manner along the guide groove 323. This not only prevents the button assembly 331 from rotating in the mounting hole 321, but also ensures that even if the second rod 31 accidentally touches the retaining ring 332 during the axial movement of the second rod 31 in the first rod 32 along the connecting structure, the retaining ring 332 will not cause the button assembly 331 to rotate in the mounting hole 321, further improving the stability and reliability of the connecting structure length adjustment process.

[0066] Optionally, combined Figure 2 and Figure 3 As shown, the inner wall of the first rod 32 is provided with a relief groove 324 at the corresponding position of the first side rod of the retaining ring 332. When the retaining ring 332 disengages from the retaining groove 312 of the second rod 31, the first side rod of the retaining ring 332 is located in the relief groove 324.

[0067] In this optional embodiment, when adjusting the length of the connecting structure, the button assembly 331 will drive the retaining ring 332 to move inward along the guide groove 323. When the retaining ring 332 disengages from the retaining groove 312, the first side rod of the retaining ring 332 is embedded in the clearance groove 324. At this time, the clearance groove 324 not only provides clearance space for the first side rod of the retaining ring 332, but also, since the first side rod of the retaining ring 332 is in the clearance groove 324 and the second side rod of the retaining ring 332 is in the guide groove 323, it can also prevent the retaining ring 332 from interfering with the up and down movement of the second rod 31 during the axial movement of the second rod 31 in the first rod 32 along the connecting structure, further improving the smoothness of the second rod 31 moving along the axial movement of the first rod 32 along the connecting structure.

[0068] Optionally, combined Figure 2 As shown, the locking structure 33 includes a locking bolt, and a locking hole 322 is provided on the first rod 32 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.

[0069] Specifically, locking bolts ( Figure 2 (Not shown in the image) can be a bolt structure. The locking hole 322 has an internal thread, so the locking bolt and the locking hole 322 are connected by a thread.

[0070] The locking bolt in the locking structure 33, together with the button assembly 331 and the retaining ring 332, can be used simultaneously or either one can be used at will, depending on the rider's needs.

[0071] In this optional embodiment, when it is necessary to adjust the length of the connecting structure, the locking bolt in the locking hole 322 is loosened 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 first rod 32. After the length of the connecting structure is adjusted, the locking bolt in the locking hole 322 is tightened until the locking bolt abuts against the slot 312 of the second rod 31. Thus, the position of the second rod 31 in the first rod 32 can also be locked by the locking bolt.

[0072] Furthermore, after the length of the connecting structure is adjusted, it can be engaged with the slot 312 of the second rod 31 by the retaining ring 332. Since the button assembly 331 connected to the retaining ring 332 is installed in the mounting hole 321 on the first rod 32, the retaining ring 332 can also lock the position of the second rod 31 in the first rod 32. The locking bolt abuts against the slot 312 of the second rod 31, so that the stability of the second rod 31 being locked in the first rod 32 is effectively improved under the dual action of the locking bolt and the retaining ring 332.

[0073] Optionally, combined Figure 3 As shown, the electric vehicle kickstand also has a leveling mechanism, which includes a base structure 1 and the above-mentioned connecting structure. The connecting structure includes a second rod 31. The base structure 1 is provided with a receiving groove 11. The end of the second rod 31 away from the first rod 32 has a connecting head 311. The connecting head 311 is embedded in the receiving groove 11 and is used to rotate within the receiving groove 11.

[0074] Specifically, 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 in the receiving groove 11. The relative rotation of the connecting structure and the base structure 1 is used to achieve the leveling of the base structure 1.

[0075] 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.

[0076] In addition, the electric vehicle kickstand also includes a wireless charging head (not shown in the figure), and a receiving cavity is provided inside the base structure 1 to facilitate the installation of the wireless charging head in the receiving cavity.

[0077] 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.

[0078] In this optional embodiment, since the wireless charging head is disposed within the accommodating cavity, the base structure 1 provides safety protection for the wireless charging head, thereby preventing the wireless charging head from being exposed to the environment and damaged by collisions with other external objects.

[0079] This application improves the structure of the existing foot support by allowing the second rod 31 in the height adjustment mechanism to move axially with the first rod 32 along the connecting structure, thereby adjusting the length of the entire electric vehicle foot support and adjusting the center of gravity height of the frame when parked. This makes it suitable for electric vehicles with different center of gravity heights. Furthermore, the connecting head 311 at the end of the second rod 31 away from the first rod 32 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. This adjustable tilt base structure 1 is suitable for various uneven surfaces. The base structure 1 is leveled with the ground 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 because the base structure 1 can rotate relative to the connecting head 311 of the second rod 31. This improves the connection 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 battery. Therefore, it is suitable for various electric vehicles that can be wirelessly charged.

[0080] Optionally, combined Figure 4 As shown, 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] This utility model provides an electric vehicle, including a frame and an electric vehicle kickstand as described above.

[0086] 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.
