[0033] In view of the problems of the above related technologies, the present embodiment provides an electric car foot prop and an electric car.

[0034] As shown in FIG. 1, the electric vehicle foot prop provided by the embodiment of the application comprises a base structure 1 and a connecting structure, the connecting structure comprises a first rod member 32 and a second rod member 31, the first rod member 32 and the second rod member 31 are arranged along the axial direction of the connecting structure, and the first rod member 32 and the second rod member 31 are movably connected along the axial direction of the connecting structure, one end of the first rod member 32 is used for connecting a vehicle frame, and the other end of the second rod member 31 away from the first rod member 32 is connected with the base structure 1.

[0035] Specifically, the electric vehicle foot prop has a height adjusting mechanism, which can be realized by the connecting structure, that is, the height adjusting mechanism comprises the first rod member 32 and the second rod member 31, and the first rod member 32 and the second rod member 31 are arranged along the axial direction of the connecting structure. For example, the top end of the first rod member 32 can be rotatably connected with the vehicle frame, and the first rod member 32 and the second rod member 31 are movably connected, and the other end of the second rod member 31 away from the first rod member 32 is connected with the base structure 1.

[0036] Among them, the first rod member 32 and the second rod member 31 movably connected along the axial direction of the connecting structure means that the second rod member 31 can adjust the connection position with the first rod member 32 along the axial direction of the connecting structure to change the length of the entire connecting structure. The size of the connecting structure in the axial direction of itself is the length of the connecting structure.

[0037] In the embodiment, the connecting structure comprises the first rod member and the second rod member arranged along the axial direction of itself, for example, the top end of the first rod member can be rotatably connected with the vehicle frame, and the other end, for example, the bottom end of the second rod member away from the first rod member is connected with the base structure, so that the first rod member of the electric vehicle foot prop rotates relative to the vehicle frame to perform the folding or falling action.

[0038] Specifically, the base structure is used for supporting on the ground in the parking state of the electric vehicle, when encountering uneven bottom surface, for example, the ground position of the electric vehicle foot prop is higher or lower than the ground position of the wheels of the electric vehicle, the connection position of the second rod member with the first rod member can be adjusted along the axial direction of the connecting structure by manual mode to adjust the length of the entire electric vehicle foot prop comprising the connecting structure, to adjust the inclination angle of the vehicle frame relative to the ground, so that the height of the gravity center of the vehicle frame in the parking state is adjusted, thereby being applicable to electric vehicles of different vehicle types with different gravity center heights, to improve the universality of the electric vehicle foot prop.

[0039] For example, if the gravity center height of the vehicle frame of different vehicle types is high, the length of the entire connecting structure can be increased accordingly, and vice versa, if the gravity center height of the vehicle frame of different vehicle types is low, the length of the entire connecting structure can be reduced accordingly, so that the electric vehicle foot prop can stably support the vehicle frame when being applicable to electric vehicles of different vehicle types.

[0040] Optionally, the connecting structure further comprises a locking structure 33, the first rod member 32 and the second rod member 31 are connected through the locking structure 33, and the locking structure 33 is used for locking the position of the second rod member 31 and the first rod member 32 after length adjustment in the axial direction of the connecting structure.

[0041] Specifically, the second rod member 31 can adjust the connection position with the first rod member 32 along the axial direction of the connecting structure, so as to adjust the length of the entire electric scooter, and thus the electric scooter can be applied to electric scooters with different center of gravity heights, and the locking structure 33 is used for locking the position of the connecting structure after length adjustment.

[0042] In the optional embodiment, after the first rod member 32 and the second rod member 31 in the connecting structure are length-adjusted in the axial direction, the relative position of the first rod member 32 and the second rod member 31 in the connecting structure after length adjustment can be locked by the locking structure, so that the force applied by the frame of the electric scooter to the electric scooter can be avoided to move the second rod member 31 along the axial direction of the connecting structure relative to the first rod member 32 when the electric scooter is in a parked state, and thus the stability of the electric scooter in the parked state can be ensured.

[0043] In the optional embodiment, after the first rod member 32 and the second rod member 31 in the connecting structure are length-adjusted in the axial direction, the relative position of the first rod member 32 and the second rod member 31 in the connecting structure after length adjustment can be locked by the locking structure, so that the force applied by the frame of the electric scooter to the electric scooter can be avoided to move the second rod member 31 along the axial direction of the connecting structure relative to the first rod member 32 when the electric scooter is in a parked state, and thus the stability of the electric scooter in the parked state can be ensured.

[0044] Optionally, the first rod member 32 and the second rod member 31 are connected in a sliding manner, and the second rod member 31 is used for sliding relative to the first rod member 32 along the axial direction of the connecting structure.

[0045] Specifically, the sliding connection of the first rod member 32 and the second rod member 31 means that the second rod member 31 can slide relative to the first rod member 32 along the axial direction of the connection structure to adjust the length of the connection structure, and the locking structure 33 can be connected to the first rod member 32 and the second rod member 31 to lock the position of the connection structure after length adjustment.

[0046] The first rod member 32 and the second rod member 31 can be connected in the following ways, for example, first, the locking structure can be a bolt fastener, and the first rod member 32 and the second rod member 31 can be movably connected by the bolt fastener. Specifically, the first rod member 32 and the second rod member 31 are both cylindrical structures, and the inner diameter of the first rod member 32 is larger 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 rod member 32 is provided with first through holes spaced along the axial direction thereof, and the second rod member 31 is provided with second through holes spaced along the axial direction thereof. After the first rod member 32 is sleeved on the second rod member 31, the second rod member 31 is moved along the axial direction of the connection structure relative to the first rod member 32, and after the length is adjusted, the bolt fastener is inserted into 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 connection structure after length adjustment.

[0047] Second, as shown in FIG. 5, the first rod member 32 has a sliding groove 325 extending along the axial direction thereof, and the second rod member 31 is provided with a sliding block structure 313 extending along the axial direction thereof, and the sliding block structure 313 is inserted into the sliding groove 325 and used to slide in the sliding groove 325.

[0048] The locking structure 33 is used to lock the position of the connection between the sliding block structure 313 and the sliding groove 325.

[0049] Specifically, at least part of the first rod member 32 can be a semi-cylindrical structure, and a sliding groove 325 is arranged inside the first rod member 32, and the extension direction of the sliding groove 325 can be parallel to the extension direction of the first rod member 32. The second rod member 31 and the sliding block structure 313 can form an integrated structure, and at least part of the second rod member 31 can also be a semi-cylindrical structure. The shape of the sliding block structure 313 matches the shape of the sliding groove 325, so that the sliding block structure 313 can be inserted into the sliding groove 325, and the second rod member 31 can be slidably connected to the first rod member 32 through the sliding block structure 313 and the sliding groove 325 of the first rod member 32 to adjust the length of the connection structure.

[0050] The locking structure 33 can be a bolt fastener, a plurality of first through holes are arranged on the first rod 32 along the axial direction of the first rod 32, a plurality of second through holes are arranged on the second rod 31 along the axial direction of the second rod 31, the second rod 31 is adjusted to move along the axial direction of the connecting structure relative to the first rod 32, and after the length is adjusted to be appropriate, the bolt fastener is arranged in the first through hole of the first rod 32 and the second through hole of the second rod 31, so as to lock the position of the connecting structure after the length is adjusted.

[0051] Thirdly, optionally, the connecting structure can also adjust the length and lock the position after the length is adjusted in the following manner, for example, as shown in FIG. 2, 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 clamping grooves 312 arranged along the axial direction of the second rod 31, and the locking structure 33 is arranged at the mounting hole 321 and used for clamping into or out of the clamping groove 312.

[0052] Specifically, the second rod 31 and the first rod 32 can be locked in position after the length is adjusted by the locking structure 33 during the relative approach or the relative departure in the axial direction of the connecting structure; the inner diameter of the sleeve structure is greater than the outer diameter of the rod-shaped second rod 31, so that the first rod 32 can be sleeved on the second rod 31. An installation hole 321 is arranged on the circumferential side wall of the first rod 32, so that the locking structure 33 can be embedded and arranged in the installation hole 321. A plurality of clamping grooves 312 are arranged along the axial direction of the second rod 31.

[0053] 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 with the base structure 1, the first rod 32 moves on the second rod 31 along the axial direction of the connecting structure to approach or depart 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 is at least 3 mm and at most 50 mm, in other words, the length adjustment range of the entire electrically driven foot stretcher is 0-47 mm.

[0054] In this optional embodiment, when the length of the connection structure needs to be adjusted, the locking structure 33 can be operated to disengage the locking structure 33 from the clamping groove 312 on the second rod member 31, so that the locking structure 33 no longer hinders the movement of the second rod member 31 relative to the first rod member 32 in the axial direction. When the second rod member 31 moves relative to the first rod member 32 in the axial direction to make the length of the connection structure meet the on-site requirements, the locking structure 33 can be operated to be clamped into the clamping groove 312 on the second rod member 31. At this time, the second rod member 31 and the first rod member 32 are connected into an integrated structure by the locking structure 33, so as to realize the locking of the position of the second rod member 31 in the first rod member 32, that is, to realize the position locking after the length adjustment of the connection structure.

[0055] Optionally, as shown in FIG. 2, the locking structure 33 includes a button assembly 331 and a clamping ring 332. The button assembly 331 is embedded in the mounting hole 321, and the clamping ring 332 is installed on the button assembly 331. The clamping ring 332 is sleeved on the second rod member 31, and is used to be clamped to or disengaged from the clamping groove 312 under the action of the button assembly 331.

[0056] 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 in the mounting hole 321 of the first rod member 32. One end of the clamping ring 332 can be installed on the button assembly 331, and the other part of the clamping ring 332 can be sleeved on the second rod member 31. The button assembly 331 can be operated to clamp the clamping ring 332 to or disengage the clamping ring 332 from the clamping groove 312.

[0057] Here, the force refers to the pushing force exerted by the rider on the button assembly 331 to disengage the clamping ring 332 from the clamping groove 312 when the length of the connection structure needs to be adjusted, or the elastic restoring force of the spring 3312 in the button assembly 331 to make the clamping ring 332 be clamped to the clamping groove 312 again after the length adjustment of the connection structure.

[0058] In this optional embodiment, when the length of the connecting structure needs to be adjusted, the button assembly 331 is pressed to allow the button assembly 331 to move inwards of the first rod 32 in the mounting hole 321, at this time, the clamping ring 332 can move inwards of the first rod 32 away from the button assembly 331 under the action force of the button assembly 331 such as a pushing force or a pressing force, so that the clamping ring 332 is disengaged from the clamping groove 312 of the second rod 31, so that the second rod 31 can move axially in the first rod 32 without being limited by the clamping ring 332 to adjust the length of the connecting structure; after the length of the connecting structure is adjusted, the button assembly 331 is released to allow the button assembly 331 to move outwards in the mounting hole 321 to reset when the external force is lost, at this time, the clamping ring 332 can be clamped again at the clamping groove 312 on the second rod 31 under the action force of the button assembly 331 such as a spring restoring force, so that the position of the second rod 31 in the first rod 32 is locked by the cooperation of the button assembly 331 and the clamping ring 332 embedded in the mounting hole 321 of the first rod 32, in other words, the position of the connecting structure after length adjustment is locked.

[0059] Optionally, in combination with FIG. 2, 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, and the clamping ring 332 is installed on the button body 3311.

[0060] Specifically, the clamping ring 332 can be installed on the button body 3311 in the following manner, for example, the button body 3311 is provided with a clamping hole, the clamping ring 332 is a U-shaped ring, and the open end of the clamping ring 332 is clamped in the clamping hole to achieve the clamping installation of the clamping ring 332 on the button body 3311.

[0061] The spring 3312 can be sleeved or embedded on the button body 3311 in the following manner, for example, if the end of the button body 3311 towards the spring 3312 has a rod-shaped structure, and the inner diameter of the spring 3312 is greater than the outer diameter of the rod-shaped structure, at this time, 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 for abutting against the second rod 31. Alternatively, if the end of the button body 3311 towards 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, at this time, 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 for abutting against the second rod 31.

[0062] In addition, the spring 3312 can be fixedly installed on the button body 3311 by one end of the spring 3312 being fixedly installed on the button body 3311 by means of adhesion, clamping, rivets, or the like. The spring 3312 can be a compression spring.

[0063] In the optional embodiment, when the length of the connection structure needs to be adjusted, the rider applies a pushing force to the button body 3311, at which time the button body 3311 transmits the pushing force to the spring 3312, at which time the spring 3312 is compressed. Since the clamping ring 332 is clamped on the button body 3311, the button body 3311 arranged in the mounting hole 321 of the first rod member 32 drives the clamping ring 332 to move in the direction of the inside of the mounting hole 321 under the action of the pushing force, so as to make the clamping ring 332 disengage from the clamping groove 312. At this time, the clamping ring 332 no longer hinders the up-and-down movement of the second rod member 31 in the first rod member 32, so that the second rod member 31 can be operated to move up and down in the first rod member 32 along the axial direction of the connection structure, so as to adjust the length of the connection structure. When the length of the connection structure is adjusted, the rider releases the button body 3311, at which time the button body 3311 loses the pushing force of the rider. After losing the pushing force of the rider, the spring 3312 uses its elastic restoring force to push the button body 3311 in the mounting hole 321 outward. In the process of the button body 3311 moving outward in the mounting hole 321, the clamping ring 332 is driven to move horizontally until it is clamped again in the clamping groove 312 of the second rod member 31, so as to realize the position locking after the length adjustment of the connection structure.

[0064] Optionally, in combination with FIG. 2, the clamping ring 332 includes a first side rod portion 3321 and two oppositely arranged second side rod portions 3322. The first side rod portion 3321 is connected to one end of the two second side rod portions 3322, and the other end of the two second side rod portions 3322 forms an open end of the clamping ring 332. The open end of the clamping ring 332 is clamped with the button assembly 331.

[0065] Specifically, the first side rod portion 3321 can adopt an arc-shaped rod structure, and the two second side rod portions 3322 can be axisymmetric structures. The second side rod portion 3322 can be a rod-shaped structure with a hook end. The two ends of the first side rod portion 3321 are respectively connected to the corresponding second side rod portions 3322 and can be configured as an integral clamping ring 332 in the shape of a U-shaped ring, so as to ensure the mechanical strength of the clamping ring 332. The hook ends of the two second side rod portions 3322 away from the first side rod portion 3321 can serve as the open end of the clamping ring 332.

[0066] In the optional embodiment, the button assembly 331 comprises a button body 3311, and the button body 3311 is provided with a clamping hole. The clamping ring 332 is a U-shaped ring, and the opening end of the clamping ring 332 is clamped in the clamping hole of the button body 3311, so that the clamping ring 332 can be quickly installed on the button body 3311 in a clamped manner, thereby improving the clamping convenience of the clamping ring 332 and the button assembly 331.

[0067] Optionally, as shown in FIGS. 2 and 3, the inner wall of the first rod member 32 is provided with a guide groove 323 at a position corresponding to the second side rod portion 3322 of the clamping ring 332, the second side rod portion 3322 of the clamping ring 332 is embedded in the guide groove 323, and the second side rod portion 3322 of the clamping ring 332 is used for linear motion along the guide groove 323.

[0068] Specifically, the inner wall of the first rod member 32 is provided with a guide groove 323, which extends along the movement direction of the button assembly 331 in the mounting hole 321. Since the clamping ring 332 comprises two second side rod portions 3322, two guide grooves 323 are opened in the inner wall of the first rod member 32, and each second side rod portion 3322 can be in a corresponding guide groove 323.

[0069] In the optional embodiment, the guide groove 323 is in the inner wall of the mounting hole 321. Since the two second side rod portions 3322 of the U-shaped clamping ring 332 are respectively embedded in the guide grooves 323, when the rider needs to adjust the length of the connecting structure by applying a pushing force to the button assembly 331, or loosen the button assembly 331 after adjusting the length of the connecting structure, the button assembly 331 in the mounting hole 321 will drive the second side rod portion 3322 of the clamping ring 332 to slide into or out of the guide groove 323 along the extension direction of the guide groove 323. Therefore, the second side rod portion 3322 of the clamping ring 332 sliding in the guide groove 323 can ensure that the button assembly 331 moves linearly in a direction along the guide groove 323, which not only avoids the rotation of the button assembly 331 in the mounting hole 321, but also ensures that the button assembly 331 does not rotate in the mounting hole 321 even if the second rod member 31 accidentally bumps the clamping ring 332 during the movement of the second rod member 31 in the first rod member 32 along the axial direction of the connecting structure, thereby further improving the stability and reliability during the length adjustment of the connecting structure.

[0070] Optionally, as shown in FIGS. 2 and 3, the inner wall of the first rod member 32 is provided with a guide groove 323 at a position corresponding to the second side rod portion 3322 of the clamping ring 332, the second side rod portion 3322 of the clamping ring 332 is embedded in the guide groove 323, and the second side rod portion 3322 of the clamping ring 332 is used for linear motion along the guide groove 323.

[0071] Specifically, the inner wall of the first rod member 32 is provided with a recess 324, and specifically, the inner wall of the first rod member 32 is provided with the recess 324 at a position corresponding to the first side rod portion 3321, and the shape of the recess 324 can match the shape of the first side rod portion 3321. For example, the first side rod portion 3321 is an arc-shaped rod structure, and the recess 324 can be an arc-shaped recess.

[0072] In this optional embodiment, when the length of the connecting structure is adjusted, the button assembly 331 drives the clamping ring 332 to move inward along the guide recess 323. When the clamping ring 332 is disengaged from the clamping groove 312, the first side rod portion 3321 of the clamping ring 332 is embedded in the recess 324. At this time, the recess 324 not only provides a space for the first side rod portion 3321 of the clamping ring 332, but also avoids interference of the clamping ring 332 with the up-down movement of the second rod member 31 during the axial movement of the second rod member 31 in the first rod member 32 along the axis of the connecting structure, thereby further improving the smoothness of the axial movement of the second rod member 31 in the first rod member 32 along the axis of the connecting structure.

[0073] Optionally, as shown in FIG. 2, the locking structure 33 includes a locking bolt, and the first rod member 32 is further provided with a locking hole 322 at a position corresponding to the clamping groove 312. The locking bolt is threadedly connected with the locking hole 322, and is used for rotating in the locking hole 322 to abut or move away from the clamping groove 312.

[0074] Specifically, the locking bolt (not shown in FIG. 2) can be a bolt structure, and the locking hole 322 has an internal thread, so that the locking bolt and the locking hole 322 are connected in a threaded manner.

[0075] The locking bolt in the locking structure 33 and the locking structure 33 composed of the button assembly 331 and the clamping ring 332 can be used simultaneously or alternatively, and the specific use can be flexibly selected according to the needs of the rider.

[0076] In this optional embodiment, when the length of the connecting structure needs to be adjusted, the locking bolt in the locking hole 322 is loosened so that the locking bolt moves away from the clamping groove 312. At this time, the locking bolt does not hinder the up-down movement of the second rod member 31 in the first rod member 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 clamping groove 312 of the second rod member 31, so that the position of the second rod member 31 in the first rod member 32 can also be locked by the locking bolt.

[0077] And, when the length of the connecting structure is adjusted, the snap ring 332 can be clamped in the clamping groove 312 of the second rod member 31. Since the button assembly 331 connected with the snap ring 332 is installed in the mounting hole 321 of the first rod member 32, the snap ring 332 can also lock the position of the second rod member 31 in the first rod member 32. The locking bolt abuts against the clamping groove 312 of the second rod member 31, so that the stability of the position of the second rod member 31 in the first rod member 32 is effectively improved under the double action of the locking bolt and the snap ring 332.

[0078] Optionally, in combination with FIG. 3, the electric foot stretcher also has a leveling mechanism, which includes a base structure 1 and the above-mentioned connecting structure.

[0079] Specifically, the second rod member 31 is provided with the connecting head 311 at one end away from the first rod member 32, for example, the bottom end. The connecting head 311 of the bottom end of the second rod member 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 can realize the leveling of the base structure 1.

[0080] 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 the spherical structure or a structure with a volume greater than half of the 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 the shape. At this time, the connecting head 311 and the receiving groove 11 are connected in a spherical hinge connection mode.

[0081] In addition, the electric foot stretcher also includes a wireless charging head (not shown in the figure). A containing cavity is arranged in the inside of the base structure 1, so as to facilitate the installation of the wireless charging head in the containing cavity.

[0082] The base structure 1 is used to support the ground.
