[0051] It should be noted that the folding electric vehicle has a cross section at the folding part. When the folding electric vehicle is folded, the cross section is exposed, resulting in corners and protrusions on the folding electric vehicle. The corners are sharp and can easily scratch the user. If the folded folding electric vehicle is stored in a backpack, it can also easily scratch the backpack, making the folding electric vehicle difficult to carry. In the embodiment of the present application, the electric vehicle 100 is stored in a telescopic manner, which can reduce the corners or protrusions of the electric vehicle 100 after storage, thereby reducing the difficulty of carrying the electric vehicle 100 after storage.

[0052] For the above rear frame assembly 1, if Figures 1 to 4 The rear frame assembly 1 includes a first chassis 11 and a driving wheel 12, and the driving wheel 12 is arranged at the bottom of the first chassis 11. The first chassis 11 can be in the shape of a rectangular parallelepiped, and can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. One end of the telescopic assembly 3 is connected to the first chassis 11. The driving wheel 12 can include a hub motor, and the hub motor is provided with an inflatable tire or a PU (polyurethane) rubber wheel. When the hub motor is powered on, it rotates relative to the first chassis 11 to drive the electric vehicle 100 to travel on the ground. Optionally, the number of the driving wheels 12 is two.

[0053] For the first chassis 11, Figure 3 As shown, a storage slot 111 is provided on the top of the first chassis 11, and a power supply interface 112 and a USB interface 113 (Universal Serial Bus) are provided in the storage slot 111. The storage slot 111 can be used to accommodate batteries, telescopic remote control 6, speed control remote control 7 and other sundries. When the battery is installed in the storage slot 111, the battery is connected to the power supply interface 112 to supply power to the driving wheel 12. The USB interface 113 can supply power to the outside, for example, to charge portable devices such as mobile phones and cameras. The number of USB interfaces 113 can be multiple, for example, four.

[0054] In some embodiments, Figure 4As shown, the rear frame assembly 1 also includes a first cover plate 13, which is detachably covered on the top of the storage slot 111. The first cover plate 13 is adapted to the shape of the first chassis 11 and can be in the shape of a rectangular plate, so that it can be covered on the top of the first chassis 11, and then cover the top of the storage slot 111 to prevent the items in the storage slot 111 from being exposed, and reduce the dust, rainwater, etc. in the external environment from invading the storage cavity. At the same time, the first cover plate 13 can be used for normal users to stand or carry goods. The first cover plate 13 can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. Optionally, the first cover plate 13 can be connected to the first chassis 11 by screws or buckles.

[0055] In some embodiments, Figure 4 As shown, the rear frame assembly 1 also includes a second cover plate 14, which is rotatably arranged on the first cover plate 13. The second cover plate 14 can be hingedly connected to one end of the first cover plate 13 at one end to be rotatably connected to the first cover plate 13. The second cover plate 14 is adapted to the shape of the first cover plate 13, and can be in the shape of a rectangular plate and have the same size, so that the first cover plate 13 and the second cover plate 14 can be folded to a fitted state, reducing the occupation of the space of the rear frame assembly 1. When the telescopic assembly 3 is extended to the preset position, the second cover plate 14 can be flipped relative to the first cover plate 13, and covered on the top of the telescopic assembly 3, so that the top of the telescopic assembly 3 can also be used for users to stand or carry goods. The second cover plate 14 can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. Among them, the preset position refers to the position when the telescopic assembly 3 is extended to the electric vehicle 100 is fully unfolded.

[0056] In some embodiments, Figure 4 As shown, the first chassis 11 is provided with a first lamp 15. The first lamp 15 may be an LED (light emitting diode) lamp, thereby providing lighting and being able to remind surrounding vehicles or pedestrians to notice the electric vehicle 100, thereby reducing the occurrence of traffic accidents. Optionally, the first lamp 15 is provided on a side of the first chassis 11 away from the second chassis 21.

[0057] In some embodiments, Figure 4 As shown, the first chassis 11 is provided with a speaker 16. The speaker 16 may be a wired speaker 16 or a Bluetooth speaker 16, and may be connected to a portable device, such as a mobile phone, to play audio, thereby increasing the fun of outdoor sports.

[0058] For the above-mentioned front frame assembly 2, if Figure 5As shown, the front frame assembly 2 includes a second chassis 21, a bogie 22 and a steering wheel 23, the bogie 22 is rotatably arranged on the second chassis 21, and the steering wheel 23 is arranged on the bogie 22. The second chassis 21 can be in the shape of a rectangular parallelepiped, and can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. One end of the telescopic assembly 3 is connected to the second chassis 21. The second chassis 21 is provided with a sleeve 211, and the bogie 22 is provided with a connecting column 221, and the connecting column 221 is penetrated in the sleeve 211 to rotatably connect the bogie 22 to the second chassis 21, and the bogie 22 can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. The steering wheel 23 can be the same as the driving wheel 12 to increase the driving performance of the electric vehicle 100, and the steering wheel 23 can also be a non-powered wheel, such as a roller or a PU rubber wheel. Optionally, the number of the steering wheels 23 is two. Optionally, a bearing is provided between the sleeve 211 and the connecting column 221 to reduce the friction between the sleeve 211 and the connecting column 221. Optionally, the second chassis 21 is provided with a buckle 212, which is detachably connected to the telescopic assembly 3, for example, by screw connection, and the buckle 212 can be provided on the sleeve 211.

[0059] In some embodiments, Figure 5 As shown, the front frame assembly 2 also includes a mounting plate 24, which is arranged on the bogie 22 and located above the second chassis 21. The mounting plate 24 can be in the shape of a rectangular plate and can be made of metal, such as aluminum alloy, steel, etc., to increase the compressive strength. The connecting column 221 passes upward through the sleeve 211 to connect with the mounting plate 24, so that the mounting plate 24 can rotate synchronously with the bogie 22. By driving the mounting plate 24 to rotate relative to the second chassis 21 by external force, the bogie 22 can be driven to rotate relative to the second chassis 21, thereby realizing the steering of the electric vehicle 100.

[0060] In some embodiments, Figure 6 and Figure 7As shown, the front frame assembly 2 further includes a first footrest 25 and a second footrest 26. The first footrest 25 is disposed on the top of the mounting plate 24, and the second footrest 26 is rotatably disposed on the first footrest 25. The second footrest 26 is used to rotate relative to the first footrest 25 to fit with the first footrest 25 or to fit with the mounting plate 24. The mounting plate 24 is provided with a first mounting hole 241, and the first footrest 25 is detachably connected to the mounting plate 24 through the first mounting hole 241, for example, detachably connected by screws. One end of the second cover plate 14 can be hingedly connected to one end of the first cover plate 13, so as to be rotatably connected to the first footrest 25. It is understandable that, since the second foot pedal 26 can be rotated to fit with the mounting plate 24, the first foot pedal 25 covers the top portion of the mounting plate 24. When the second foot pedal 26 is rotated to fit with the first foot pedal 25, the second foot pedal 26 is located on the side of the first foot pedal 25 away from the mounting plate 24, so that the first foot pedal 25, the second foot pedal 26 and the mounting plate 24 form an "L"-shaped support, which is convenient for the user's sole to step on, which is conducive to improving the user's stepping comfort; and the first foot pedal 25 and the second foot pedal 26 have equal thickness. When the user steps on the first foot pedal 25 and the second foot pedal 26, the mounting plate 24 can be driven to rotate relative to the second chassis 21 by applying force, so as to realize the steering of the electric vehicle 100.

[0061] Furthermore, in some embodiments, Figure 6 and Figure 7 As shown, the first footrest 25 includes a first inclined surface 251 on the side facing the rear frame assembly 1, and the second footrest 26 includes a second inclined surface 261 on the side facing the first footrest 25; when the second footrest 26 rotates to fit with the first footrest 25, the second inclined surface 261 and the first inclined surface 251 are located in the same plane. It can be understood that if the second footrest 26 wants to rotate relative to the first footrest 25, the first inclined surface 251 must be inclined in a direction away from the second chassis 21, and when the user sits on the seat assembly 4, the first inclined surface 251 faces the user. When the second foot pedal 26 is rotated to fit with the first foot pedal 25, the first slope 251 and the second slope 261 are both facing the user. The user steps on the first slope 251 and the second slope 261, which can be more convenient for the user to step on and further improve the user's stepping comfort; when the second foot pedal 26 is rotated to fit with the mounting plate 24, the first slope 251 and the second slope 261 are in contact, and the second foot pedal 26 and the first foot pedal 25 are spliced ​​into a complete rectangular plate, so that the second foot pedal 26 and the first foot pedal 25 are easy to store.

[0062] In some embodiments, Figure 7As shown, the second chassis 21 is provided with a second lamp 27. The second lamp 27 may be an LED (light emitting diode) lamp, thereby providing lighting and being able to remind surrounding vehicles or pedestrians to notice the electric vehicle 100, thereby reducing the occurrence of traffic accidents. Optionally, the second lamp 27 is provided on a side of the second chassis 21 away from the first chassis 11.

[0063] In some embodiments, Figure 5 As shown, the second chassis 21 is provided with a lock 28. The lock 28 can be a telescopic wire password lock, and the second chassis 21 can be locked to a building or a pillar by pulling out the wire, and the password lock can be used to prevent others from unlocking the lock.

[0064] For the above telescopic component 3, if Figure 8 As shown, the telescopic assembly 3 includes a telescopic rod 31 and a first electric push rod 32. The two ends of the telescopic rod 31 are respectively connected to the first chassis 11 and the second chassis 21, so as to slidably connect the second chassis 21 to the first chassis 11. The number of telescopic rods 31 can be two, and the two telescopic rods 31 are respectively connected to the left and right sides of the first chassis 11 to increase the strength and stability of the sliding connection between the first chassis 11 and the second chassis 21. The two ends of the first electric push rod 32 are respectively connected to the first chassis 11 and the second chassis 21. The first electric push rod 32 is parallel to the telescopic rod 31. When the first electric push rod 32 telescopes, it can drive the second chassis 21 to translate relative to the first chassis 11. Optionally, the telescopic rod 31 is a load-bearing three-section ball slide rail. Optionally, the first electric push rod 32 is an electric cylinder.

[0065] In some embodiments, the buckle 212 is detachably connected to the first electric push rod 32. When the first electric push rod 32 is damaged, the first electric push rod 32 can be disconnected from the buckle 212, so that the telescopic component 3 can be manually stretched to unfold the electric vehicle 100.

[0066] For the above-mentioned seat assembly 4, as Figure 6 and Figure 8 As shown, the seat assembly 4 includes a four-bar linkage 41 and a seat plate 42. The four-bar linkage 41 includes a first rod 411, a second rod 412, a third rod 413 and a fourth rod 414 which are connected end to end in sequence. It can be understood that the first rod 411, the second rod 412, the third rod 413 and the fourth rod 414 are connected in a ring shape, and the first rod 411 can rotate relative to the second rod 412, the second rod 412 can rotate relative to the third rod 413, the third rod 413 can rotate relative to the fourth rod 414, and the fourth rod 414 can rotate relative to the first rod 411, and the rotation axes of the first rod 411, the second rod 412, the third rod 413 and the fourth rod 414 are parallel to each other. Among them, the first rod 411, the second rod 412, the third rod 413 and the fourth rod 414 are connected by a connecting shaft.

[0067] Among them, Figure 8 As shown, the first rod 411 is arranged on the first chassis 11; the seat plate 42 is arranged on the third rod 413. When the second rod 412 is driven to rotate relative to the first rod 411, the seat plate 42 moves up and down relative to the first chassis 11, and at the same time moves in a horizontal direction. When the seat plate 42 descends to contact with the first chassis 11, the seat plate 42 is folded relative to the first chassis 11; when the seat plate 42 rises, the seat plate 42 is unfolded relative to the first chassis 11. In the embodiment of the present application, when the seat plate 42 rises relative to the first chassis 11, the seat plate 42 simultaneously moves in a translational motion toward the rear of the electric vehicle 100, and the seat assembly 4 tilts backward when unfolded, increasing the space for the user's legs and improving riding comfort. When the seat plate 42 is folded relative to the first chassis 11, the first cover plate 13 and the second cover plate 14 are located below the seat plate 42; when the seat plate 42 is unfolded relative to the first chassis 11, the second cover plate 14 can be turned over, and the first cover plate 13 can also be removed.

[0068] Furthermore, the length of the first rod 411 is equal to the length of the third rod 413, and the length of the second rod 412 is equal to the length of the fourth rod 414, so that the seat plate 42 is always parallel to the first chassis 11, and the seat plate 42 can be attached to the top of the first chassis 11 when folded relative to the first chassis 11; when the seat plate 42 is unfolded relative to the first chassis 11, it can always be horizontal, which is convenient for riding and improves riding comfort. It should be noted that the length of the first rod 411, the length of the third rod 413, the length of the second rod 412, and the length of the fourth rod 414 here refer to the distance between the rotation axes at both ends of each rod, and do not include the part beyond the rotation axis.

[0069] In some embodiments, Figure 6 and Figure 8 As shown, the seat assembly 4 further includes a second electric push rod 43, one end of which is rotatably connected to the connecting shaft between the first rod 411 and the second rod 412, and the other end of which is rotatably connected to the connecting shaft between the third rod 413 and the fourth rod 414. The second electric push rod 43 is used for telescopic movement to drive the seat plate 42 to fold or unfold relative to the first chassis 11. It can be understood that the two ends of the second electric push rod 43 are respectively connected to the two opposite corners of the four-bar linkage 41. When the second electric push rod 43 telescopic movement, the second rod 412 rotates relative to the first rod 411, and at the same time drives the third rod 413 and the fourth rod 414 to rotate, thereby driving the seat plate 42 to translate relative to the first chassis 11, so as to realize the folding or unfolding of the seat plate 42 relative to the first chassis 11. Optionally, the second electric push rod 43 is an electric cylinder.

[0070] In some embodiments, Figure 6As shown, the seat assembly 4 also includes a backboard 44, which is rotatably arranged on the seat board 42, and the backboard 44 is used to rotate, fold and store relative to the seat board 42 or rotate to open to a first preset angle. The backboard 44 can be hingedly connected to one end of the seat board 42 at one end to be rotatably connected to the seat board 42.
