In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.

[0051] See also Figure 1The embodiment of the present application provides an electric vehicle, which includes a front wheel mechanism 11, a rear wheel assembly 12 and a seat assembly 13. The front wheel mechanism 11 includes a front wheel 111, a front wheel bracket 112 and an adjustment assembly 113. The adjustment assembly 113 is connected to the front wheel bracket 112, and one end of the front wheel bracket 112 is connected to the front wheel 111. The rear wheel assembly 12 includes a rear wheel 121 and a rear wheel bracket 122. One end of the rear wheel bracket 122 is rotatably connected to the adjustment assembly 113, and the other end of the rear wheel bracket 122 is connected to the rear wheel 121. One end of the seat assembly 13 is rotatably connected to one end of the front wheel bracket 112. The seat assembly 13 and the rear wheel bracket 122 are cross-arranged and rotatably connected at the intersection. The adjustment assembly 113 is used to drive one end of the rear wheel bracket 122 to move toward a direction close to one end of the seat assembly 13 so that the electric vehicle can be unfolded. Please refer to Figure 2 Alternatively, the adjustment assembly 113 is used to drive one end of the rear wheel bracket 122 to move in a direction away from one end of the seat assembly 13 so that the electric vehicle can be folded.

[0052] In the above electric vehicle, the seat assembly 13 and the rear wheel bracket 122 are cross-arranged so that the seat assembly 13 and the rear wheel bracket 122 are roughly in an X-shaped structure and are rotatably connected at the intersection, so that when the adjustment assembly 113 drives one end of the rear wheel bracket 122 to move in a direction away from the one end of the seat assembly 13, the seat assembly 13 and the rear wheel bracket 122 can be quickly retracted toward the front wheel mechanism 11 to achieve the folding of the electric vehicle, and when the adjustment assembly 113 drives one end of the rear wheel bracket 122 to move in a direction close to the one end of the seat assembly 13, the seat assembly 13 and the rear wheel bracket 122 can be quickly unfolded to achieve the unfolding of the electric vehicle; in this way, the distance between one end of the rear wheel bracket 122 and one end of the seat assembly 13 is adjusted by the adjustment assembly 113, so as to achieve the rapid folding and unfolding of the electric vehicle, and the structure of the electric vehicle is simple, and the space after folding is smaller. At the same time, there is only a rotating movement structure between the seat assembly 13 and the rear wheel bracket 122, which is simple in structure and has better stability, thereby improving the stability of the electric vehicle.

[0053] Specifically, the folding direction of the electric vehicle is the front-to-back direction when the user rides the electric vehicle.

[0054] See also Figure 3 In some embodiments, the adjustment assembly 113 includes a screw 1131 and a threaded sleeve 1132, the screw 1131 extends along the inclination direction of the front wheel bracket 112, and both ends of the screw 1131 are rotatably connected to the front wheel bracket 112, the threaded sleeve 1132 is sleeved on the screw 1131 and threadedly connected to the screw 1131, and one end of the rear wheel bracket 122 is rotatably connected to the threaded sleeve 1132.

[0055] In this way, the lead screw 1131 is driven to rotate by an external force, and the lead screw 1131 drives the threaded sleeve 1132 to move along the lead screw 1131 through the thread, and the threaded sleeve 1132 drives one end of the rear wheel bracket 122 to move toward or away from one end of the seat assembly 13, so as to drive the seat assembly 13 and the rear wheel bracket 122 to expand or contract, thereby realizing the expansion or folding of the electric vehicle. The position of one end of the rear wheel bracket 122 is adjusted by the lead screw 1131 and the threaded sleeve 1132, and one end of the rear wheel bracket 122 can be adjusted to any position and automatically locked, so as to quickly fold and unfold the electric vehicle. The operation is convenient and fast, and the structure is simple. At the same time, the seat 132 on the seat assembly 13 can also be adjusted to any height, thereby improving the user's car experience.

[0056] Furthermore, the lead screw 1131 and the threaded sleeve 1132 may be made of alloy steel, stainless steel or high-strength non-metallic materials (eg, polytetrafluoroethylene).

[0057] Please also read Figure 1 and Figure 2 Furthermore, a strip groove 1124 is provided on the front wheel bracket 112, the lead screw 1131 is received in the strip groove 1124, and the threaded sleeve 1132 is slidably connected to the groove wall of the strip groove 1124, and the strip groove 1124 is used to guide the threaded sleeve 1132 to move along the extension direction of the lead screw 1131 to improve the stability of the threaded sleeve 1132 during movement.

[0058] In some embodiments, the adjustment component 113 can also be other structures. For example, the adjustment component 113 is a locking block, which is slidably connected to the front wheel bracket 112, and the front wheel bracket 112 is provided with a plurality of slots, and the locking block is engaged with the slots. By sliding the locking block along the front wheel bracket 112 until it is engaged in the corresponding slots, the folding and storage of the electric vehicle and the adjustment of the height of the seat 132 on the seat assembly 13 can be achieved.

[0059] See also Figure 3 In some embodiments, the adjustment assembly 113 further includes a driving member 1133 , which is connected to the front wheel bracket 112 and the lead screw 1131 , and the driving member 1133 is used to drive the lead screw 1131 to rotate, so as to drive the threaded sleeve 1132 to move.

[0060] In this way, the driving member 1133 drives the lead screw 1131 to rotate automatically, and the lead screw 1131 drives the threaded sleeve 1132 to move through the thread, so as to realize the automatic unfolding and automatic folding of the electric vehicle, making the operation of the electric vehicle more convenient, thereby improving the user experience.

[0061] In this embodiment, the structure of the driving member 1133 is not limited. For example, the driving member 1133 can be a motor, which directly drives the screw 1131 to rotate; or, the driving member 1133 includes a driving gear, a driven gear and a motor that are meshed with each other, the motor is connected to the driving gear, the driven gear is connected to the screw 1131, and the motor drives the screw 1131 to rotate through the driving gear and the driven gear, so as to adjust the configuration position of the motor, thereby optimizing the spatial structure of the electric vehicle; or, the driving member 1133 includes an active roller, a driven roller, a transmission belt and a motor, the motor is connected to the active roller, the active roller and the driven roller are connected through a transmission belt, the driven roller is connected to the screw 1131, and the motor drives the screw 1131 to rotate through the active roller, the driven roller and the transmission belt, so as to adjust the configuration position of the motor, thereby optimizing the spatial structure of the electric vehicle.

[0062] See also Figure 4 In some embodiments, the seat assembly 13 includes a seat bracket 131 and a seat 132, one end of the seat bracket 131 is rotatably connected to one end of the front wheel bracket 112, the seat bracket 131 and the rear wheel bracket 122 are cross-arranged and rotatably connected at the intersection, and the seat 132 is foldably connected to the other end of the seat bracket 131.

[0063] In this way, the seat 132 is flipped from a horizontal state to an inclined state to be folded, and the distance between the seat 132 and the front wheel bracket 112 in the front-to-back direction is reduced to avoid the seat 132 interfering with the folding of the seat bracket 131, so that the space after the electric vehicle is folded is smaller.

[0064] Furthermore, a cross hole 1311 is provided on the seat bracket 131, and the rear wheel bracket 122 passes through the cross hole 1311, and the opposite sides of the rear wheel bracket 122 are rotatably connected to the hole wall of the cross hole 1311, so that the hole wall of the cross hole 1311 forms a supporting structure to support the stable rotation of the rear wheel bracket 122, thereby further improving the firmness between the rear wheel bracket 122 and the seat bracket 131.

[0065] See also Figure 4In some embodiments, a first hinge position 1321 and a second hinge position 1322 are provided on the seat 132, and the first hinge position 1321 and the second hinge position 1322 are arranged at intervals along the folding direction of the electric vehicle. The seat 132 is hinged to the seat bracket 131 at the first hinge position 1321; the seat assembly 13 also includes a connecting member 133, one end of the connecting member 133 is hinged to the seat 132 at the second hinge position 1322, and the other end of the connecting member 133 is hinged to the rear wheel bracket 122. Specifically, the hinge position between the other end of the connecting member 133 and the rear wheel bracket 122 is adjacent to the intersection between the rear wheel bracket 122 and the seat assembly 13, and is biased towards the position close to the rear wheel 121, and the connecting member 133 is movably inserted into the seat bracket 131. When the electric vehicle is folded, the rear wheel bracket 122 pulls the seat 132 to flip through the connecting member 133.

[0066] During the folding action, when the adjustment component 113 drives one end of the rear wheel bracket 122 to move toward the end away from the seat component 13, the seat component 13 and the rear wheel bracket 122 move closer to the front wheel bracket 112 to realize the folding of the electric vehicle. During the flipping process of the rear wheel bracket 122, the seat 132 is pulled by the connecting member 133 to flip from a horizontal state to an inclined state, thereby realizing the automatic folding of the seat 132; in this way, during the folding of the electric vehicle, the rear wheel bracket 122 automatically folds the seat 132 through the connecting member 133 during the flipping process of itself, thereby improving the convenience and flexibility of the operation of the electric vehicle, and further improving the user's vehicle experience.

[0067] Furthermore, the connecting member 133 is a connecting rod. When the electric vehicle is unfolded, the adjustment component 113 drives one end of the rear wheel bracket 122 to move toward the end close to the seat component 13, and the seat component 13 and the rear wheel bracket 122 move away from the front wheel bracket 112 to realize the unfolding of the electric vehicle. During the flipping process of the rear wheel bracket 122, the rear wheel bracket 122 pushes the seat 132 to flip from a tilted state to a horizontal state, thereby realizing automatic resetting of the seat 132.

[0068] Alternatively, the connecting member 133 is a traction rope, and when the electric vehicle is unfolded, the seat 132 is automatically reset by its own gravity.

[0069] See also Figure 3 In some embodiments, there are two front wheels 111, and the two front wheels 111 are spaced apart along a direction perpendicular to the folding direction of the electric vehicle, and each front wheel 111 is rotatably connected to a front wheel bracket 112. The front wheel mechanism 11 also includes a handle assembly 114, and one end of the handle assembly 114 is linked to the two front wheels 111 to drive the two front wheels 111 to turn synchronously.

[0070] In this way, when the user turns the handle assembly 114 to steer, the two front wheels 111 are driven to steer synchronously, thereby achieving stable steering.

[0071] Please also read Figure 3 and Figure 5 Furthermore, the handle assembly 114 includes a handle body 1141, a handle support rod 1142, a linkage 1143 and two connecting rods 1144. The handle support rod 1142 is rotatably arranged in the front wheel bracket 112, and the handle body 1141 is connected to one end of the handle support rod 1142, one end of the linkage 1143 is connected to the other end of the handle body 1141, one end of each connecting rod 1144 is rotatably connected to the other end of the linkage 1143, and the other end of each connecting rod 1144 is connected to a corresponding front wheel 111. When the handle body 1141 is driven by an external force to drive the handle support rod 1142 to rotate, the handle support rod 1142 drives the two front wheels 111 to turn synchronously through the linkage 1143 and the two connecting rods 1144.

[0072] When turning, the user rotates the handle body 1141, and the handle body 1141 drives the handle support rod 1142 and the linkage member 1143 to rotate. When the linkage member 1143 rotates, the two front wheels 111 are driven to rotate synchronously through the two connecting rods 1144, thereby realizing flexible steering of the two front wheels 111 and convenient operation.

[0073] See also Figure 1 In some embodiments, the front wheel bracket 112 includes a bracket body 1121, two connecting frames 1122 and two shock absorbers 1123. The bracket body 1121 is rotatably connected to one end of the seat assembly 13, and the handlebar support rod can rotatably pass through the bracket body 1121, and the two are connected to the opposite sides of the bracket body 1121. The two shock absorbers 1123 are arranged at intervals along a direction perpendicular to the folding direction of the electric vehicle (that is, the left and right direction when the user rides the electric vehicle), and each shock absorber 1123 is connected to a corresponding connecting frame 1122 and is used to carry a corresponding front wheel 111, and each front wheel 111 is rotatably connected to a corresponding shock absorber 1123 so that the front wheel 111 can rotate around the shock absorber 1123; the electric vehicle is damped by the shock absorber 1123 to improve the comfort of the user when riding.

[0074] Specifically, each shock absorber 1123 is provided with an axis, and the axis is perpendicular to the center line of the front wheel 111 , and each front wheel 111 rotates around the axis on the corresponding shock absorber 1123 .

[0075] See also Figure 1 In some embodiments, the front wheel bracket 112 further includes two footrests 1125, which are connected to opposite sides of the bracket body 1121 to facilitate supporting the user's feet.

[0076] The present embodiment does not limit the structure of the pedal member 1125. For example, the pedal member 1125 may be a rod-shaped structure or a plate-shaped structure.

[0077] See also Figure 1 In some embodiments, the electric vehicle further includes an energy storage member 14, which is mounted on the other end of the rear wheel bracket 122 and electrically connected to the drive wheel to supply power to the drive wheel, wherein the front wheel 111 is configured as a drive wheel, or the rear wheel 121 is configured as a drive wheel, or both the front wheel 111 and the rear wheel 121 are configured as drive wheels. An exemplary energy storage member 14 may be a battery.

[0078] In this way, by installing the energy storage component 14 to the other end of the rear wheel bracket 122, the weight distribution of the front and rear parts of the electric vehicle is more balanced, so as to improve the stability of the electric vehicle when riding. By configuring the front wheel 111 as a driving wheel, the electric vehicle has better traction performance; by configuring the rear wheel 121 as a driving wheel, the front wheel 111 is only responsible for steering, reducing the burden on the front wheel 111, thereby improving the control experience of the electric vehicle. At the same time, configuring the rear wheel 121 as a driving wheel is conducive to further balancing the weight of the front and rear parts of the electric vehicle, thereby further improving the stability of the electric vehicle when riding; by configuring the front wheel 111 and the rear wheel as driving wheels at the same time, the traction and grip of the electric vehicle are further improved, thereby helping the electric vehicle to respond to emergencies on the ground more quickly, reducing the risk of accidents, and improving riding safety.

[0079] Furthermore, the energy storage component 14 is detachably connected to the other end of the rear wheel bracket 122 to facilitate disassembly and installation of the energy storage component 14 .

[0080] Furthermore, an energy storage bin is disposed at the rear end of the rear wheel bracket 122 , and the energy storage component 14 is stored in the energy storage bin. The energy storage bin is used to store and protect the energy storage component 14 , so as to improve the safety of the energy storage component 14 .

[0081] See also Figure 1 In some embodiments, the electric vehicle further includes a storage member 15, which is connected to the front wheel bracket 112, so that the user can store items carried by the storage member 15, thereby improving the convenience of travel. Exemplarily, the storage member 15 can be a storage frame, a storage box, a storage rack or a storage box.

[0082] In some embodiments, the rear wheel bracket 122 and the seat bracket 131 are both tubular structures to reduce the weight of the electric vehicle.
