[0033] In view of the problems existing in the above related technologies, this embodiment provides an electric vehicle footrest.

[0034] As Figure 1 shown, an electric vehicle footrest provided by an embodiment of the present utility model includes a base structure 1, a connection structure 3, and a wireless charging head 2. The wireless charging head 2 is disposed within the base structure 1. A receiving groove 11 is provided on the base structure 1. One end of the connection structure 3 is used to connect to the frame of the electric vehicle. The other end of the connection structure 3 has a connection head 311. The connection head 311 is embedded in the receiving groove 11, and the connection head 311 is used to rotate within the receiving groove 11.

[0035] Specifically, the electric vehicle footrest of the present utility model is applicable to various electric vehicles, such as electric bicycles, electric motorcycles, etc. As long as the electric vehicle has a footrest and needs to be plugged into a charging pile for wireless charging due to having a battery, it is applicable to this technical solution, and no specific limitation is made here.

[0036] The part above the base structure 1 of the electric vehicle footrest is defined as the connection structure 3 here.

[0037] One end of the connection structure 3, such as the top end, is rotatably connected to the frame of the electric vehicle, and the bottom end of the connection structure 3 is connected to the base structure 1, so that the base structure 1 and the connection structure 3 can rotate relative to the frame, so as to realize that the electric vehicle footrest rotates and drops to support the ground when stopped relative to the frame, or rotates and retracts when riding.

[0038] The connection head 311 at the bottom end of the connection structure 3 is embedded in the receiving groove 11 of the base structure 1 to realize the rotational connection between the bottom end of the connection structure 3 and the base structure 1. The following matching methods can be adopted between the receiving groove 11 of the base structure 1 and the connection head 311. For example, the inner diameter of the receiving groove 11 matches the outer diameter of the connection head 311, or the inner diameter of the receiving groove 11 is slightly larger than the connection head 311.

[0039] The receiving groove 11 can be opened on the upper part of the base structure 1, which is beneficial for the receiving groove 11 of the base structure 1 to be sleeved outside the connection head 311 of the connection structure 3.

[0040] In this embodiment, the electric vehicle footrest mainly includes a base structure 1, a connection structure 3, and a wireless charging head 2. Among them, one end of the connection structure 3, such as the top end, is used to connect to the frame of the electric vehicle, and the other end of the connection structure 3, such as the bottom end, has a connection head 311. The base structure 1 is provided with a receiving groove 11. By embedding the connection head 311 in the receiving groove 11, the connection head 311 can rotate within the receiving groove 11. In other words, the connection structure 3 connected to the frame can rotate relative to the base structure 1.

[0041] A charging pile is provided on the ground of the fixed parking area. The wireless charging head 2 is used to plug into the charging pile. For example, the charging pile has a guiding groove, and the wireless charging head 2 is a male plug. When the electric vehicle stops in the fixed parking area, the connecting structure 3 rotates with the vehicle frame to operate the connecting structure 3 to rotate and fall, so that the base structure 1 of the electric vehicle footrest supports on the ground. During this process, the base structure 1 of the electric vehicle footrest can rotate relative to the connecting structure 3 to change its angle with the horizontal plane, and can be applicable to various uneven ground surfaces. Since the wireless charging head 2 is arranged in the base structure 1, the rotation of the base structure 1 of the electric vehicle footrest relative to the connecting structure 3 can also make the base structure 1 plug into the charging pile more accurately through the wireless charging head 2, not only ensuring the charging operation of the electric vehicle, but also improving the charging efficiency of the electric vehicle battery due to the better plugging of the base structure into the guiding groove of the charging pile through the wireless charging head 2.

[0042] This application improves the structure of the existing footrest, that is, the base structure can rotate relative to the connecting structure 3 to be applicable to various uneven ground surfaces for leveling operations, so as to be applicable to various electric vehicles that can perform wireless charging operations.

[0043] Optionally, as shown in Figure 2 the base structure 1 includes a first mounting seat 12 and a second mounting seat 13. First grooves 121 and second grooves 131 are respectively formed on the first mounting seat 12 and the second mounting seat 13. The second mounting seat 13 is detachably connected to the first mounting seat 12, and the second groove 131 and the first groove 121 enclose to form the receiving groove 11.

[0044] Specifically, the base structure 1 can form the receiving groove 11 in the following way. For example, the base structure 1 can be divided into two parts, namely the first mounting seat 12 and the second mounting seat 13. The first groove 121 is formed on the first mounting seat 12, and the second groove 131 is formed on the second mounting seat 13. The inner diameters of the first groove 121 and the second groove 131 can be equal or unequal.

[0045] In addition, the base structure 1 formed by assembling the first mounting seat 12 and the second mounting seat 13 can take the extension direction of the connecting structure 3 as the initial position and rotate relative to the connecting head 311 of the connecting structure 3, and the base structure 1 can perform universal rotation relative to the connecting structure 3 in any direction. Among them, 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 from 0 degree to 10 degrees.

[0046] The connecting head 311 can be at least one of a spherical structure, an incomplete spherical structure, a horizontally arranged cylindrical structure, etc. The incomplete spherical structure refers to half of a spherical structure, or a structure with a volume greater than half of a spherical structure; if the connecting head 311 is a spherical structure or an incomplete spherical structure, the receiving groove 11 is a spherical groove structure corresponding to its shape. At this time, the connecting head 311 and the receiving groove 11 are connected in a ball joint manner.

[0047] The second mounting seat 13 can be detachably connected to the first mounting seat 12 in the following manners, for example, by bolt fasteners, snap fasteners, clamps, etc. Take the bolt fasteners as an example for illustration, for example, the number of bolt-fastened parts is at least two, a plurality of through holes are provided on the first mounting seat 12, and a plurality of threaded holes are provided on the second mounting seat 13, the number of the through holes matches the number and position of the threaded holes, and the bolt fasteners are passed through the through holes of the first mounting seat 12 and connected to the threaded holes of the second mounting seat 13, so as to realize the detachable connection between the first mounting seat 12 and the second mounting seat 13.

[0048] In this optional embodiment, since the first mounting seat 12 and the second mounting seat 13 are detachably connected, when the connecting head 311 at the bottom end of the connecting structure 3 is assembled with the receiving groove 11 of the base structure 1, the first mounting seat 12 and the second mounting seat 13 are in a separated state, and then the connecting head 311 of the connecting structure 3 is embedded in the second groove 131 of the second mounting seat 13, and then the first mounting seat 12 is snapped onto the second mounting seat 13, so that the first groove 121 and the second groove 131 are combined to form the receiving groove 11 that is sleeved 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 seat 12 and the second mounting seat 13 to remove the connecting head 311 from the receiving groove 11 of the base structure 1, thereby improving the convenience of disassembly and assembly of the base structure 1 and the connecting structure 3.

[0049] Optionally, combined Figure 3 As shown, the base structure 1 also includes a base body 14 , the base body 14 is provided with a receiving cavity, the wireless charging head 2 is arranged in the receiving cavity, and at least one of the first mounting seat 12 and the second mounting seat 13 is arranged on the base body 14 .

[0050] Specifically, at least one of the first mounting seat 12 and the second mounting seat 13 being disposed on the base body 14 means that the first mounting seat 12 or the second mounting seat 13 is disposed on the base body 14 , or both of the first mounting seat 12 and the second mounting seat 13 are mounted on the base body 14 .

[0051] See Figure 3As shown, the second mounting base 13 and the first mounting base 12 can be semi-cylindrical structures respectively. Among them, since the electric vehicle footrest is arranged at an angle with the ground when supporting the ground, the axis of the second mounting base 13 is arranged at an acute or obtuse angle with the surface of the base body 14, so that the base body 14 can better fit the ground under the action of rotation through the receiving groove 11 formed by the first mounting base 12 and the second mounting base 13 and the connection head 311 of the connection structure 3.

[0052] A receiving cavity is arranged inside the base body 14 to facilitate the installation of the wireless charging head 2 in the receiving cavity.

[0053] The base body 14 is used to support on the ground. The base body 14 can be inserted into the guiding groove of the charging pile in the following way. For example, the bottom of the base body 14 is provided with a plugging protrusion, and the base body 14 can be inserted into the guiding groove of the charging pile through the plugging protrusion.

[0054] In this optional embodiment, since the wireless charging head 2 is arranged in the receiving cavity, the base body 14 is used to provide safety protection for the wireless charging head 2 to prevent the wireless charging head 2 from being damaged by being collided with other external objects when exposed to the environment.

[0055] In the related art, an electric vehicle of one model can only be matched with an electric vehicle footrest of a corresponding specification, such as length. When the electric vehicle footrest of this specification is installed on the frame of an electric vehicle of other models, if the length of the electric vehicle footrest is short, it may cause the frame of the electric vehicle to tip over towards the direction of the electric vehicle footrest. If the length of the electric vehicle footrest is long, for example, after supporting the frame of the electric vehicle, the angle between the frame and the ground is greater than 75 degrees. At this time, the electric vehicle may tip over towards the direction without the electric vehicle footrest under the action of a little external force, resulting in poor versatility of the electric vehicle footrest.

[0056] Optionally, in combination with Figure 4 and Figure 5 As shown, the connection structure 3 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 connection structure 3, and the first rod 32 and the second rod 31 are movably connected along the axial direction of the connection structure 3. One end of the first rod 32 is used to connect the frame, and the end of the second rod 31 away from the first rod 32 has the connection head 311.

[0057] Specifically, the connection structure is used to adjust the center of gravity height of the frame of the electric vehicle. The connection structure 3 can be divided into two parts, namely the first rod member 32 and the second rod member 31, and the first rod member 32 and the second rod member 31 can be arranged along the axial direction of the connection structure 3. One end of the first rod member 32, such as the top end, can be rotatably connected to the frame, and the first rod member 32 and the second rod member 31 can be movably connected. The end of the second rod member 31 away from the first rod member 32, such as the bottom end, has the connection head 311, and the connection head 311 at the bottom end of the second rod member 31 can be embedded in the receiving groove 11 of the base structure 1.

[0058] Wherein, the fact that the first rod member 32 and the second rod member 31 are movably connected along the axial direction of the connection structure 3 means that the second rod member 31 can adjust its connection position with the first rod member 32 along the axial direction of the connection structure 3 to change the length of the entire connection structure 3. The dimension of the connection structure 3 in its own axial direction is the length of the connection structure 3.

[0059] In this alternative embodiment, since the first rod member 32 and the second rod member 31 are movably connected along the axial direction of the connection structure 3, the connection position of the second rod member 31 and the first rod member 32 can be adjusted manually to adjust the length of the entire connection structure 3, so that the connection structure 3 can be applicable to electric vehicles of different models; in addition, when encountering an uneven bottom surface, for example, the ground position where the footrest of the electric vehicle is located is higher or lower than the ground position where the wheels of the electric vehicle are located, by adjusting the length of the connection structure 3, the inclination angle of the frame of the electric vehicle relative to the ground can be adjusted, so that the center of gravity height of the frame in the parking state is adjusted. For example, if the center of gravity height of the frames of different models is relatively high, the length of the entire connection structure 3 can be increased accordingly. On the contrary, if the center of gravity height of the frames of different models is relatively low, the length of the entire connection structure 3 can be reduced accordingly, so that the footrest of the electric vehicle can stably support the frame when applicable to electric vehicles of different models.

[0060] Therefore, the present application improves the structure of the existing footrest, that is, the second rod member 31 can adjust its connection position with the first rod member 32 along the axial direction of the connection structure 3 to adjust the length of the entire electric vehicle footrest, so that it can be applicable to electric vehicles with different center of gravity height models; and the end of the second rod member 31 away from the first rod member 32 has the connection head 311, which can rotate in the receiving groove 11 of the base structure 1 to be applicable to various uneven ground surfaces for leveling operations, so that the wireless charging head 2 in the base structure 1 can be better inserted into the guiding groove of the charging pile, and further applicable to various electric vehicles that can perform wireless charging operations.

[0061] Exemplary illustration, the first rod and the second rod in the connecting structure 3 can be movably connected in the following ways. For example, the first rod member 32 and the second rod member 31 are threadedly connected. Specifically, the first rod member 32 is a cylindrical structure, and the second rod member is a cylindrical structure or a cylindrical structure. Moreover, the inner diameter of the first rod member 32 is greater than the outer diameter of the second rod member 31. The first rod member 32 is sleeved on the second rod member 31. The inner wall of the first rod member 32 is provided with internal threads, and the outer wall of the second rod member 31 is provided with external threads. The internal threads of the first rod member 32 are threadedly connected to the external threads of the second rod member 31. The second rod member 31 can move axially relative to the first rod member 32 along the connecting structure 3 by rotation to adjust the length of the connecting structure 3.

[0062] Alternatively, for example, the first rod member 32 and the second rod member 31 can be movably connected by means of bolt fasteners. Specifically, the first rod member 32 and the second rod body are respectively cylindrical structures, and the inner diameter of the first rod member 32 is greater than the outer diameter of the second rod member 31. The first rod member 32 is sleeved on the second rod member 31. The first through holes are arranged at intervals along the axial direction of the first rod member 32, and the second through holes are arranged at intervals along the axial direction of the second rod member 31. After the first rod member 32 is sleeved on the second rod member 31, by adjusting the second rod member 31 to move axially relative to the first rod member 32 along the connecting structure 3, after adjusting to an appropriate length, the bolt fasteners can be passed through the first through holes of the first rod member 32 and the second through holes of the second rod member 31 to lock the position of the connecting structure 3 after length adjustment.

[0063] Alternatively, the connecting structure 3 can also adjust the length and lock the position after length adjustment in the following way. For example, as shown in Figure 5 The connecting structure 3 further includes a locking structure 33. The first rod member 32 is a sleeve structure, and the second rod member 31 is a support rod. The second rod member 31 is sleeved on the first rod member 32. The first rod member 32 is provided with an installation hole 321, and the second rod member 31 is provided with a plurality of card slots 312 arranged at intervals along its axial direction. The locking structure 33 is arranged at the installation hole 321, and the locking structure 33 is used to engage or disengage from the card slots 312.

[0064] Specifically, the second rod member 31 and the first rod member 32 can lock the position after length adjustment through the locking structure 33 during the process of relatively approaching or relatively moving away in the axial direction of the connecting structure 3; the inner diameter of the sleeve structure is greater than the outer diameter of the second rod member 31 in the shape of a rod, so as to facilitate the first rod member 32 to be sleeved on the second rod member 31. An installation hole 321 is opened on the circumferential side wall of the first rod member 32 to facilitate the locking structure 33 to be installed in the installation hole 321 in an embedded manner. A plurality of card slots 312 are arranged at intervals along the axial direction of the second rod member 31.

[0065] In the connecting structure 3, the length is adjusted by the second rod 31 and the first rod 32, so that the length of the entire connecting structure 3 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 3 on the second rod 31 to approach or move away from the base structure 1, so that the distance between the bottom end of the first rod 32 and the upper end of the base structure 1 can be at least 3 mm and at most 50 mm. In other words, the length adjustment range of the entire electric vehicle footrest is 0 - 47 mm.

[0066] In this alternative embodiment, when it is necessary to adjust the length of the connecting structure 3, the locking structure 33 can be operated to disengage the locking structure 33 from the card slot 312 on the second rod 31. At this time, the locking structure 33 no longer hinders 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 3 meet the on-site requirements, the locking structure 33 can be operated at this time to make it snap into the card slot 312 on the second rod 31. At this time, the second rod 31 and the first rod 32 are connected into an integral structure through the locking structure 33, so as to realize the locking of the position of the second rod 31 in the first rod 32. In other words, to realize the position locking after the length adjustment of the connecting structure 3.

[0067] Optionally, as shown in Figure 5 the locking structure 33 includes a button assembly 331 and a snap ring 332. The button assembly 331 is embedded in the mounting hole 321. The snap ring 332 is installed on the button assembly 331. The snap ring 332 is sleeved on the second rod 31. The snap ring 332 is used to be snapped into or disengaged from the card slot 312 under the action of the button assembly 331.

[0068] Specifically, the size of the mounting hole 321 is slightly larger than that of the button assembly 331 to facilitate the smooth installation of the button assembly 331 into the mounting hole 321 of the first rod 32. One end of the snap ring 332 can be installed on the button assembly 331, and other parts of the snap ring 332 can be sleeved on the second rod 31. By operating the button assembly 331, the snap ring 332 can be snapped into or disengaged from the card slot 312.

[0069] Among them, the acting force refers to the thrust applied by the rider to the button assembly 331 when it is necessary to adjust the length of the connecting structure 3 to disengage the snap ring 332 from the card slot 312; or, after the length adjustment of the connecting structure 3, the elastic restoring force of the spring 3312 in the button assembly 331 to make the snap ring snap into the card slot 312 again.

[0070] In this optional embodiment, when it is necessary to adjust the length of the connection structure 3, by pressing the button assembly 331, the button assembly 331 can move inward in the installation hole 321 in the direction of the interior of the first rod 32. At this time, the snap ring 332 can move away from the button assembly 331 in the first rod 32 under the action of the button assembly 331, such as a thrust or a pressing force, so that the snap ring 332 disengages from the card slot 312 of the second rod 31, enabling the second rod 31 to move axially in the first rod 32 without being restricted by the snap ring 332 to adjust the length of the connection structure 3. After the length of the connection structure 3 is adjusted, release the button assembly 331 so that the button assembly 331 moves outward in the installation hole 321 to reset when the external force is lost. At this time, the snap ring 332 can be snapped again at the card slot 312 on the second rod 31 under the action of the button assembly 331, such as an elastic restoring force. By the cooperation of the button assembly 331 and the snap ring 332 embedded in the installation hole 321 of the first rod 32, the position of the second rod 31 in the first rod 32 is locked, in other words, the position of the connection structure 3 after length adjustment is locked.

[0071] The button assembly 331 and the snap ring 332 can adopt the following specific structures. For example, in combination Figure 5 as shown, the button assembly 331 includes a button body 3311 and a spring 3312. The button body 3311 is provided with a card slot. The snap ring 332 is a U-shaped ring. The open end of the snap ring 332 is snapped into the card slot to install the snap ring 332 on the button body 3311 in a snap-fit manner. 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 support rod.

[0072] The spring 3312 can be a compression spring 3312. When the length of the connection structure 3 needs to be adjusted, the rider applies a thrust to the button body 3311. At this time, the button body 3311 transmits this thrust to the spring 3312, and the spring 3312 is compressed. Since the snap ring 332 is clamped on the button body 3311, the button body 3311 disposed in the mounting hole 321 of the first rod 32 can drive the snap ring 332 to move away from the button assembly 331 under the action of this thrust, so that the snap ring 332 disengages from the card slot 312. At this time, the snap ring 332 no longer hinders the up and down movement of the second rod 31 in the first rod 32, so that the second rod 31 can be operated to move up and down along the axial direction of the connection structure 3 in the first rod 32 to adjust the length of the connection structure 3; after the length of the connection structure 3 is adjusted, the rider releases the button body 3311. At this time, the button body 3311 loses the thrust of the rider. After losing the thrust of the rider, the spring 3312 uses its own elastic restoring force to push the button body 3311 in the mounting hole 321 outwards. During the process of the button body 3311 moving outwards in the mounting hole 321, it drives the snap ring 332 to move horizontally until it is clamped in the card slot 312 of the second rod 31 again, thereby realizing the position locking after the length adjustment of the connection structure 3.

[0073] Optionally, as shown in combination with Figure 6 The snap ring 332 includes a first side rod portion and two second side rod portions arranged oppositely. The first side rod portion is connected to one ends of the two second side rod portions, and an opening end of the snap ring 332 is formed between the other ends of the two second side rod portions. The first side rod portion and the two second side rod portions enclose a U-shaped ring; at a position corresponding to the second side rod portion of the snap ring 332 on the inner wall of the first rod 32, a guiding groove 323 is provided. The second side rod portion of the snap ring 332 is embedded in the guiding groove 323, and the second side rod portion of the snap ring 332 is used for linearly moving along the radial direction of the first rod 32 in the guiding groove 323.

[0074] Specifically, the guiding groove 323 is located on the inner wall of the mounting hole 321. Since the two second side rod portions of the snap ring 332, which is a U-shaped ring, are respectively embedded in the guiding groove 323, when the rider needs to adjust the length of the connecting structure 3, a thrust is applied to the button assembly 331, or when the length of the connecting structure 3 is adjusted and the button assembly 331 is released, at this time, the button assembly 331 in the mounting hole 321 will drive the second side rod portion of the snap ring 332 to slide into or out of the guiding groove 323 along the radial direction of the first rod 32. Therefore, the snap ring 332 sliding in the guiding groove 323 can ensure that the button assembly 331 moves linearly along the radial direction of the first rod 32, not only avoiding the rotation of the button assembly 331 in the mounting hole 321, but also during the axial movement of the second rod 31 in the first rod 32 along the connecting structure 3, even if the second rod 31 accidentally touches the snap ring 332, at this time, the snap ring 332 will not drive the button assembly 331 to rotate in the mounting hole 321, further improving the stability and reliability during the length adjustment of the connecting structure 3.

[0075] Optionally, as shown in combination with Figure 6 a relief groove 324 is provided at the corresponding position between the inner wall of the first rod 32 and the first side rod portion of the snap ring 332. When the snap ring 332 is disengaged from the card slot 312 of the second rod 31, the first side rod portion of the snap ring 332 is located in the relief groove 324.

[0076] Specifically, when adjusting the length of the connecting structure 3, the button assembly 331 will drive the snap ring 332 to move radially inward along the first rod 32. When the snap ring 332 is disengaged from the card slot 312, the first side rod portion of the snap ring 332 is embedded in the relief groove 324. At this time, the relief groove 324 not only provides a relief space for the first side rod portion of the snap ring 332, but also since the first side rod portion of the snap ring 332 is located in the relief groove 324 and the second side rod portion of the snap ring 332 is located in the guiding groove 323, it can also avoid the interference of the snap ring 332 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 3, further improving the smoothness of the axial movement of the second rod 31 in the first rod 32 along the connecting structure 3.

[0077] Optionally, as shown in combination with Figure 5 a locking structure 33 includes a locking bolt. A locking hole 322 is further provided at the position on the first rod 32 corresponding to the card slot 312. The locking bolt is threadedly connected to the locking hole 322, and the locking bolt is used to rotate in the locking hole 322 to abut against or away from the card slot 312.

[0078] 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 card 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 3 is adjusted, tighten the locking bolt in the locking hole 322 until the locking bolt abuts against the card slot 312 of the second rod 31, so that the position of the second rod 31 in the first rod 32 can also be locked by the locking bolt.

[0079] Among them, the locking bolt in the locking structure 33 and the locking structure 33 composed of the button assembly 331 and the snap ring 332 can be used simultaneously or either one can be selected optionally, and can be flexibly selected according to the needs of the rider.

[0080] In the related art, an electric vehicle mainly includes an electric vehicle footrest and a vehicle frame. The electric vehicle footrest mainly includes a base structure 1 and a connecting structure 3. Among them, the top end of the connecting structure 3 is rotatably connected to the vehicle frame, and the bottom end of the base structure 1 is used to support on the ground. Generally, an electric vehicle of one model can only be matched and installed with an electric vehicle footrest of a corresponding specification. For example, when the vehicle frame is supported on the ground by the electric vehicle footrest, the vehicle frame is inclined in the direction of the electric vehicle footrest. At this time, the included angle between the extension line of the connecting structure 3 (such as the part connected to the base structure 1 in the electric vehicle footrest) and the ground is within a certain angle range (such as 30 degrees to 75 degrees), so that the bottom end of the electric vehicle footrest can be close to the vertical line where the center of gravity of the inclined vehicle frame is located, so that the vehicle frame can be parked stably.

[0081] However, when the electric vehicle footrest of this specification is installed on the vehicle frame of an electric vehicle of other models, if the base structure 1 of the electric vehicle footrest deviates too far from the center of gravity of the vehicle frame of this model of electric vehicle, so that the included angle between the extension line of the connecting structure 3 and the ground is not within the above angle range, it may cause the vehicle frame to tip over in the direction of the electric vehicle footrest, resulting in poor versatility of the electric vehicle footrest.

[0082] Therefore, as shown in Figure 1 An electric vehicle footrest is provided in an embodiment of the present invention. The electric vehicle footrest includes a base structure 1, a connecting structure 3, and a wireless charging head 2. The wireless charging head 2 is arranged in the base structure 1. A receiving groove 11 is provided on the base structure 1. One end of the connecting structure 3 is used to connect the vehicle frame of the electric vehicle, and the other end of the connecting structure 3 has a connecting head 311. The connecting head 311 is embedded in the receiving groove 11, and the connecting head 311 is used to rotate in the receiving groove 11.

[0083] Optionally, as shown in Figure 7 and Figure 8As shown, the connection structure 3 includes a connecting rod structure 34 and a connection seat 35. The connection seat 35 is used to connect to the vehicle frame. The connecting rod structure 34 is movably connected to the connection seat 35. One end of the connecting rod structure 34 away from the connection seat 35 has the connection head 311.

[0084] Specifically, the connection structure 3 is used to adjust the relative position of the base structure 1 and the center of gravity of the vehicle frame. Specifically, one end of the connection seat 35 is rotatably connected to the vehicle frame. One end of the connecting rod structure 34, such as the top end, is movably connected to the connection seat 35. In other words, the connecting rod structure 34 can move relative to the connection seat 35. And one end of the connecting rod structure 34 away from the connection seat 35, such as the bottom end, has the connection head 311, and the connection head 311 is embedded in the receiving groove 11 of the base structure 1. The connecting rod structure 34 is a component between the connection seat 35 and the base structure 1. Briefly, the connecting rod structure 34 of the connection structure 3 moves in a certain degree of freedom relative to the connection seat 35, and then drives the base structure 1 at the bottom end of the connecting rod structure 34 to move away from or close to the vehicle frame in the left - right direction of the vehicle frame.

[0085] In this optional embodiment, since the connecting rod structure 34 is movably connected to the connection seat 35, the connection head 311 at the bottom end of the connecting rod structure 34 is embedded in the receiving groove 11 of the base structure 1, and the connection position of the connection seat 35 and the vehicle frame is fixed. Thus, the base structure 1 can move relative to the connection seat 35 along the left - right sides of the vehicle frame through the connecting rod structure 34, so that the included angle between the extension line of the adjusted connecting rod structure 34 and the ground is within the above - mentioned angle range, so that the base structure 1 is close to the center of gravity of the vehicle frame of this type of electric vehicle, thereby ensuring the stability of the support for the vehicle frames of different types of electric vehicles.

[0086] Preferably, the connecting rod structure 34 can be composed of the above - mentioned first rod 32 and second rod 31.

[0087] Therefore, this application makes a structural improvement to the existing footrest of the prior art. For example, the electric vehicle footrest has a leveling mechanism, a height - adjusting mechanism, and a center - of - gravity adjusting mechanism. Specifically, the leveling mechanism, the height - adjusting mechanism, and the center - of - gravity adjusting mechanism are arranged in sequence along the entire length direction of the electric vehicle footrest.

[0088] The leveling mechanism includes a connection structure 3 and a base structure 1. The connection structure 3 includes a connection head 311. The base structure 1 has a receiving groove 11. The connection head 311 is embedded in the receiving groove 11 and can rotate in the receiving groove 11. The leveling of the base structure 1 is realized by the relative rotation of the connection structure 3 and the base structure 1.

[0089] The height adjustment mechanism can be realized through the connecting structure 3, that is, the height adjustment mechanism includes a first rod 32 and a second rod 31. The top end of the first rod 32 is rotatably connected to the fixed part of the vehicle frame. The first rod 32 and the second rod 31 are movably connected along the axial direction of the connecting structure 3 to adjust the support height of the electric vehicle footrest. Wherein, the bottom end of the second rod 31 has a connecting head 311, and the connecting head 311 can be embedded in the receiving groove 11 of the base structure 1.

[0090] The center of gravity adjustment mechanism includes a connecting rod structure 34, a first fastener and a connecting seat 35. The connecting seat 35 is used to connect the vehicle frame. The first fastener 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 around the axis where the first fastener is located, so that the base structure 1 at the bottom end of the connecting rod structure 34 moves away from or close to the vehicle frame in the left-right direction of the vehicle frame, thereby changing the support inclination angle and height of the vehicle frame, thereby changing the position of the center of gravity of the vehicle frame. And the center of gravity adjustment mechanism can also cooperate with the height adjustment mechanism to further increase the adjustment range of the relative position between the base structure 1 and the center of gravity of the vehicle frame, so as to adjust the center of gravity of the vehicle frames of different models. One end of the connecting rod structure 34 away from the connecting seat 35 has the connecting head 311, and the connecting head 311 can be embedded in the receiving groove 11 of the base structure 1.

[0091] In the present invention, the connecting head 311 at the end of the second rod 31 away from the first rod 32 in the leveling mechanism can rotate in the receiving groove 11 of the base structure 1 to adjust the inclination angle of the base structure 1 relative to the horizontal plane, so as to be applicable to various uneven ground through the base structure 1 with adjustable inclination angle, and realize the leveling between the base structure 1 and the ground, so that the wireless charging head 2 in the base structure 1 can be better inserted into the guiding groove of the charging pile; and through the second rod 31 in the height adjustment mechanism being movable along the axial direction of the connecting structure 3 relative to the first rod 32, the length of the entire electric vehicle footrest can be adjusted to adjust the center of gravity height of the vehicle frame in the parking state, so as to not only realize the stable support of vehicle models with different center of gravity heights, but also because the base structure 1 can rotate relative to the connecting head 311 of the second rod 31, the angle adjustment range of the base structure 1 relative to the horizontal plane can be increased, and the insertion accuracy of the wireless charging head 2 in the base structure 1 into the guiding groove of the charging pile and the wireless charging efficiency of the charging pile for the battery of the electric vehicle through the wireless charging head 2 can be correspondingly improved.

[0092] Furthermore, in the center of gravity adjustment mechanism, the connecting rod structure 34 can move relative to the connecting seat 35 along the left and right sides of the vehicle frame to adjust the relative position between the base structure 1 connected to the connecting rod structure 34 and the center of gravity of the vehicle frame, so that the base structure 1 is close to the center of gravity of the vehicle frame of this type of electric vehicle, and can cooperate with the height adjustment mechanism. For example, the first rod 32 and the second rod 31 can move axially along the connecting structure 3 to further increase the adjustment range of the relative position between the base structure 1 and the center of gravity of the vehicle frame, and further improve the support stability of the vehicle frame of models with different center of gravity heights, so that the footrest of this electric vehicle can be better applied to various electric vehicles that can perform wireless charging operations.

[0093] Exemplarily, the connecting rod structure 34 can be movably connected to the connecting seat 35 in the following manner. For example, the connecting seat 35 has a plurality of connecting holes arranged vertically, and the top end of the connecting rod structure 34 can be fixedly connected to the corresponding connecting hole by means of fasteners such as pins and buckles. For example, according to the center of gravity of the vehicle frame of different models of electric vehicles, the connecting rod structure 34 can be selectively connected to the connecting holes at different positions on the connecting seat 35. On the basis of the fixed length of the connecting rod structure 34, the angle between the extension line of the connecting rod structure 34 and the ground can be effectively adjusted within the above angle range, so as to stably support the vehicle frame of the electric vehicle.

[0094] For another example, the connecting rod structure 34 can be movably connected to the connecting seat 35 in the following manner. Specifically, the connecting structure 3 further includes a first fastener, the first fastener passes through the connecting seat 35 and the connecting rod structure 34, and the connecting rod structure 34 is used to rotate relative to the connecting seat 35 around the axis where the first fastener is located.

[0095] Specifically, the first fastener can extend along the front and rear directions of the vehicle frame, and the first fastener can be horizontally arranged and pass through the connecting rod structure 34 and the connecting seat 35 to connect the connecting rod structure 34 and the connecting seat 35 together.

[0096] Among them, the connecting rod structure 34 can rotate relative to the connecting seat 35 together with the first fastener, or can rotate relative to the connecting seat 35 around the axis where the first fastener is located.

[0097] In addition, the connecting rod structure 34 of the connecting structure 3 is used to rotate relative to the connecting seat 35 in a certain degree of freedom around the axis where the first fastener is located, thereby driving the base structure 1 at the bottom of the connecting rod structure 34 to move away from or close to the frame in the left and right directions of the frame. When the extension line of the connecting seat 35 and the extension line of the connecting rod structure 34 coincide, the position where the connecting rod structure 34 is located 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 where the connecting rod structure 34 is located is the end position of the rotation. Since the electric vehicle kick support is usually installed on the left side wall of the frame, the maximum angle of rotation of the connecting rod structure 34 to the left / outward (i.e., away from the frame) can be 15 degrees, and the maximum angle of rotation of the connecting rod structure 34 to the right / inward (i.e., toward the frame) can be 5 degrees.

[0098] In this optional embodiment, when the electric vehicle kickstand is suitable for installation on the frames of electric vehicles of different models, the position of the base structure 1 can be estimated according to the position of the vertical line of the center of gravity of the frame, and then the connecting rod structure 34 is adjusted to rotate relative to the connecting seat 35 around the axis where the first fastener is located, until the angle between the extension line of the connecting rod structure 34 and the ground is within the above-mentioned angle range. At this time, the base structure 1 is close to the vertical line where the center of gravity of the frame of the model is located. In other words, the connecting rod structure 34 is rotated relative to the connecting seat 35 around the axis where the first fastener is located to adjust the front and rear position of the base structure at the lower end of the connecting rod structure 34, thereby achieving stable support for the electric vehicle of the corresponding model.

[0099] Optionally, combined Figure 8 and Figure 9 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 close to 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, and the first fastener passes through the centers of the first toothed disc 351 and the second toothed disc 341.

[0100] Specifically, the connecting seat 35 and the connecting rod structure 34 can adopt the following structure to achieve angle adjustment and position locking after angle adjustment. For example, a first toothed disc 351 is set on the connecting seat 35, and a second toothed disc 341 is set on the connecting rod structure 34 at one end close to the connecting seat 35, such as the top end. The opposite surfaces of the first toothed disc 351 and the second toothed disc 341 respectively have tooth portions, and the tooth portions are formed by multiple protrusions arranged in a ring-shaped interval.

[0101] The first toothed disc 351 is meshed with the second toothed disc 341 and can be connected by a first fastener ( Figure 8 and Figure 9(not shown in the figure) is inserted through the centers of the first gear disc 351 and the second gear disc 341 to connect and fix the connecting seat 35 and the connecting rod structure 34.

[0102] The first fastener is a bolt fastener, and the bolt fastener includes a fastening bolt and a fastening nut.

[0103] In this alternative embodiment, the connecting rod structure 34 and the connecting seat 35 can be rotated in the following manner and the position after rotation can be locked. For example, loosen or remove the first fastener, separate the second gear disc 341 of the connecting rod structure 34 from the first gear disc 351 of the connecting seat 35, and then the connecting rod structure 34 can be operated to rotate relative to the connecting seat 35 around the axis where the first fastener is located, so that the included angle between the extension line of the connecting rod structure 34 and the horizontal plane is within the above angle range. Subsequently, the second gear disc 341 is meshed and connected with the first gear disc 351, and the fastening bolt of the first fastener is inserted through the centers of the first gear disc 351 and the second gear disc 341 and the fastening nut is connected. At this time, the tooth parts of the first gear disc 351 and the second gear disc 341 can be meshed, and the first fastener can be used to lock the position of the current rotation angle of the connecting rod structure 34 and the connecting seat 35 to prevent the connecting rod structure 34 from rotating relative to the connecting seat 35 during use.

[0104] In the related art, an electric vehicle mainly includes an electric vehicle footrest and a vehicle frame. The electric vehicle footrest mainly includes a base structure 1 and a connecting structure 3. Among them, the top end of the connecting structure 3 is rotatably connected to the vehicle frame, and the bottom end of the base structure 1 is used to support on the ground. For example, the connecting structure 3 can be rotatably connected to the vehicle frame in the following manner. Specifically, one end of the connecting structure 3 away from the base structure 1 has a connecting seat 35, and there is a fixing part at the position on the vehicle frame corresponding to the electric vehicle footrest. The fixing part can be a fixing plate structure. The connecting seat 35 is a U-shaped frame structure 352. The U-shaped frame structure 352 is sleeved on the fixing part of the vehicle frame and fixed by a fastener.

[0105] Generally, the thicknesses of the fixing parts of the vehicle frames of electric vehicles of different models are not the same, so that the fixing parts on the vehicle frames of electric vehicles of one model can only fixedly install and match the corresponding specifications of electric vehicle footrests. For example, when the U-shaped frame structure 352 of the electric vehicle footrest of this specification is installed on the vehicle frame of other models, it is very likely that the opening end size of the U-shaped frame structure 352 of the electric vehicle footrest is much larger than the thickness of the fixing part, resulting in problems of loose connection and instability, or the opening end size of the U-shaped frame structure 352 is smaller than the thickness of the fixing part, resulting in the problem that the connecting seat 35 cannot be sleeved on the fixing part, which leads to poor versatility of the electric vehicle footrest.

[0106] Optionally, in combination with Figure 9As shown, one end of the connecting structure 3 away from the base structure 1 has a connecting seat 35; the connecting seat 35 includes a U-shaped frame structure 352 and a second fastener 353. A fixing portion is provided on the vehicle frame. The U-shaped frame structure 352 is used for inserting into the fixing portion, and the second fastener 353 passes through the U-shaped frame structure 352 and the fixing portion.

[0107] Specifically, the U-shaped frame structure 352 has an open end. The connecting seat 35 can be connected to the fixing portion of the vehicle frame in the following manner. For example, the U-shaped frame structure 352 is inserted outside the fixing portion, and then the second fastener 353 passes through the U-shaped frame structure 352 and the fixing portion, so as to realize the rotational connection between the connecting seat 35 and the fixing portion. The connecting seat 35 can rotate relative to the fixing portion around the axis where the second fastener 353 is located.

[0108] In this alternative embodiment, since the U-shaped frame structure 352 can be inserted into fixing portions with different thicknesses, and the U-shaped frame structure 352 and the fixing portion are fixed by passing the second fastener 353 through them. In other words, the connecting seat 35 can be assembled with the vehicle frames of electric vehicles of different models to improve the versatility of the footrest of the electric vehicle.

[0109] Optionally, in combination with Figure 9 As shown, the connecting seat 35 further includes a gasket 354. The gasket 354 is used for inserting into the U-shaped frame structure 352, and the second fastener 353 passes through the U-shaped frame structure 352, the gasket 354 and the fixing portion of the vehicle frame.

[0110] Specifically, the thickness of the gasket 354 included in the connecting seat 35 is adjustable. For example, at least one rubber elastic sheet with elastic compressible deformation can be used, or a hard elastic sheet with variable quantity can be used. A perforation for facilitating the passing of the second fastener 353 is provided at the center of the elastic sheet.

[0111] Exemplarily, when the footrest of the electric vehicle is assembled with the vehicle frames of electric vehicles of different models, the size of the open end of the U-shaped frame structure 352 of the connecting seat 35 can be compared with the thickness of the fixing portion of the vehicle frame, and then at least one rubber elastic sheet or an appropriate number of hard elastic sheets can be selected and pre-installed into the open end of the U-shaped frame structure 352. Subsequently, the second fastener 353 passes through the U-shaped frame structure 352, the gasket 354 and the fixing portion of the vehicle frame in sequence, so as to not only realize the rotational connection between the connecting seat 35 and the fixing portion, but also use at least one rubber elastic sheet or an appropriate number of hard elastic sheets to make there be no large gap between the open end of the U-shaped frame structure 352 and the fixing portion after the connection, so as to reduce the shaking margin between the U-shaped frame structure 352 and the fixing portion, and further realize the stable connection between the connecting seat 35 and the fixing portion of the vehicle frame.

[0112] Optionally, in combination with Figure 10 and Figure 11 As shown, the entire kickstand of the electric vehicle can adopt the following structural form. For example, the kickstand of the electric vehicle includes a base structure 1, a wireless charging head 2, and a connection structure 3. Among them, the connection structure 3 includes a second rod 31, a locking structure 33, and a first rod 32. The wireless charging head 2 is arranged inside the base structure 1; the bottom end of the second rod 31 is rotatably connected to the base structure 1, and the first rod 32 is movably connected to the second rod 31 along the axial direction of the connection structure 3. The top end of the first rod 32 is used for rotatably connecting to the vehicle frame.

[0113] For example, the base structure 1 includes a base body 14, a first mounting seat 12, and a second mounting seat 13. A first groove 121 is formed on the first mounting seat 12, and a second groove 131 is formed on the second mounting seat 13. The first groove 121 and the second groove 131 enclose a receiving groove 11. The bottom end of the second rod 31 has a connecting head 311. The connecting head 311 of the second rod 31 is embedded in the receiving groove 11 and is used for rotating in the receiving groove 11 to adjust the base structure 1 to be suitable for an uneven bottom surface. At least one of the first mounting seat 12 and the second mounting seat 13 is mounted on the base body 14. The base body 14 is provided with a receiving cavity, and the wireless charging head 2 is arranged in the receiving cavity. There is a charging ground pile in the fixed parking area marked by lines in the city. The charging ground pile has a guiding groove. Since the base structure 1 can rotate relative to the second rod 31, the wireless charging head 2 at the bottom of the base structure 1 with an adjustable inclination angle can be inserted into the guiding groove of the charging ground pile more accurately.

[0114] The first rod member 32 includes a connecting sleeve 36 which is of a sleeve structure. The second rod member 31 is a support rod. The connecting sleeve 36 is sleeved on the second rod member 31. An installation hole 321 is provided on the connecting sleeve 36.

The snap ring 332 is sleeved on the second rod member 31. A plurality of card slots 312 are provided on the second rod member 31 at intervals along its axial direction. The snap ring 332 is used to be clamped in or disengaged from the card slots 312 under the action of the button assembly 331. For example, when the rider applies a thrust to the button assembly 331, the button assembly 331 drives the snap ring 332 to move towards the inside of the connecting sleeve 36 in the installation hole 321, so that the snap ring 332 disengages from the card slot 312. At this time, the second rod member 31 can be operated to slide up and down in the connecting seat 35. After adjusting the lengths of the first rod member 32 and the second rod member 31, the button assembly 331 can be released, so that the button assembly 331 moves outwards in the installation hole 321 by using its own elastic restoring force to reset, so that the snap ring 332 is clamped in the card slot 312 of the second rod member 31 again, thereby realizing the position locking of the connecting sleeve 36 of the first rod member 32 and the second rod member 31 after the length adjustment, and effectively improving the center of gravity height of the vehicle frame to improve the support stability for vehicle frames of different models.

[0115] The first rod member 32 further includes a connecting seat 35, a second sprocket 341 and a first fastener. The connecting seat 35 is provided with a first sprocket 351.

The axes of the first sprocket 351 and the second sprocket 341 are perpendicular to the extending direction of the connecting rod structure 34. The first sprocket 351 and the second sprocket 341 are arranged oppositely and meshed with each other. The first fastener passes through the centers of the first sprocket 351 and the second sprocket 341. When the first fastener is loosened or removed, the connecting sleeve 36 can be operated to rotate relative to the connecting seat 35 to realize angle adjustment. After rotating to a suitable position, the first fastener is tightened to realize the position locking of the first sprocket 351 and the second sprocket 341 after rotation. Since the bottom end of the second rod member 31 is connected to the base structure 1, the connecting structure 3 composed of the first rod member 32 and the second rod member 31 can drive the base structure 1 to approach the center of gravity position of the vehicle frame in the left-right direction, so as to achieve the purpose of stably supporting vehicle frames of different models. Among them, the connecting sleeve 36 and the second sprocket 341 can be of an integral structure.

[0116] The connecting seat 35 includes a U-shaped frame structure 352 and a second fastener 353. A fixing part is provided on the vehicle frame. The U-shaped frame structure 352 is used for plugging into the fixing parts with different thicknesses, and the second fastener 353 passes through the U-shaped frame structure 352 and the fixing part. The connecting seat 35 further includes a first sprocket 351. The U-shaped frame structure 352 and the first sprocket 351 can be an integral structure, so as to improve the mechanical strength of the connecting seat 35.

[0117] Combined Figure 11 As shown, the second rod 31 is provided with a through groove 313 penetrating along the axis, and the base body 14 is provided with a wire passing hole. The wire passing hole is communicated with the through groove 313. The wireless charger 2 is installed at the bottom of the base body 14. The cable electrically connected to the wireless charger 2 can pass through the wire passing hole of the base body 14 and then pass upward along the through groove 313 of the second rod 31, and finally can pass out from the U-shaped frame structure 352 of the connecting seat 35, and can be connected to the charging switch of the electric vehicle.
