Technical Field

[0001] The present invention relates to the technical field of electric scooters, and in particular to an electric scooter with rotatable and foldable pedals. Background Art

[0002] The electric scooter is based on the traditional human-powered scooter, with an electric kit added. It is a vehicle that integrates multiple functions such as transportation and entertainment. Its main features are: small size, simple structure, light weight and flexibility. In order to facilitate storage, save storage space or load it into the trunk of a car for carrying, foldable electric scooters have also come into being.

[0003] The foldable electric scooters in the prior art are mainly of a two-section folding structure, that is, only the upright handle portion is foldable, and the overall width after folding is limited by the width of the pedals. In order to make the folded scooter smaller, the pedals are usually designed to be narrower, and the space for the footrest is limited, which greatly reduces the riding comfort and safety. Summary of the invention

[0004] In view of the above problems, the present invention proposes an electric scooter with a rotatable and foldable pedal, which has a wide pedal width, high comfort and safety, is easy to store, and has a small volume after storage.

[0006] In order to achieve the folding of the pedal assembly, while increasing the pedal width, improving riding comfort and safety, and reducing the storage space after storage, the front pedal connecting part and the rear pedal connecting part are respectively fixedly connected with shaft sleeves, and the two shaft sleeves are arranged oppositely and coaxially. The pedal assembly is arranged between the front wheel assembly and the rear wheel assembly and the two ends are respectively sleeved and connected to the two shaft sleeves through bearings to achieve the flipping of the pedal assembly. The pedal assembly includes a pedal, a battery, two side support blocks, a middle support block, and a rotation locking mechanism. The pedal is a hollow shell structure and the inner cavity of the pedal is symmetrically provided with two support ribs, the support ribs divide the inner cavity of the pedal into an accessory compartment and two battery compartments, the battery is arranged in the battery compartment, the side support blocks and the middle support block are both arranged in the accessory compartment and fixedly connected to the pedal, and the two side support blocks are symmetrically arranged on both sides of the middle support block and correspond to the two shaft sleeves respectively.

[0007] In order to facilitate connection and improve strength, further, the side support block is an I-beam structure.

[0008] In order to improve the connection reliability between the front wheel assembly, the rear wheel assembly and the pedal assembly, further, a spacer is provided between the front end of the pedal and the front frame, and between the rear end of the pedal and the rear frame, the front end and the rear end of the pedal are provided with a spacer hole, one end of the spacer has a stopper that cooperates with the spacer hole, the spacer is sleeved on the shaft sleeve and is inserted into the spacer hole of the pedal through the stopper.

[0009] The rotary locking mechanism is used to control the locking of the pedal assembly when the scooter is in use, and the disengagement and flipping of the pedal assembly when the scooter needs to be stored, and includes a locking block and a locking block disengagement device. The locking block is arranged in the side support block and a spring is arranged between the locking block and the side support block.

[0038] The locking block disengaging device 72 can drive the locking block 71 to move axially in the side support block 33 to disengage or jam the shaft sleeve 5. The locking block disengaging device 72 includes a knob 721, a pull rope driving block 722, two connecting blocks 723, and two pull ropes 724. The connecting block 723 is fixedly connected to the locking block 71. The knob 721 is fixedly connected to the pull rope driving block 722 through a connecting rod 725. The pull rope driving block 722 is a centrally symmetrical multi-arc structure. The pull rope driving block 722 has pull rope connecting parts 7221 on both sides. The pull rope connecting parts 7221 are provided with pull rope connecting parts. The hole groove 7222, the pull rope connection hole groove 7222 is a semi-open structure, having a limit block hole 7223, a longitudinal avoidance groove 7224 and a transverse avoidance groove 7225, one end of the pull rope 724 has a limit block 7241, one end of the pull rope 724 is arranged in the pull rope connection hole groove 7222 through the limit block 7241, and the other end is fixedly connected to the connection block 723, and the pull rope driving block 722 can be driven to rotate by rotating the knob 721, thereby driving the pull ropes 724 on both sides to pull or loosen the connection block 723, and then drive the locking block 71 to disengage or jam the sleeve 5.

[0039] The bottom surface of the pedal 31 is provided with a window 311 corresponding to the positions of the two side support blocks 33 and the middle support block 34. The window 311 is provided with a bottom plate 35 whose shape matches the shape of the window. The bottom plate 35 is embedded in the window 311 and is fixedly connected to the side support blocks 33 and the middle support block 34. The pedal 31 and the bottom plate 35 together form a closed structure. A knob cavity 351 is concave inwardly in the middle of the bottom plate 35. The knob 721 is arranged on the outside of the bottom plate 35 and in the knob cavity 351. The middle support block 34 is a semi-enclosed shell structure with an open bottom and a rope avoidance groove 341. The rope drive block is arranged in the middle support block 34. The rope 724 passes through the rope connection hole groove 7222 of the rope drive block 722 and the rope avoidance groove 341 of the middle support block 34 in sequence and extends outward.

[0040] The use and folding principle of the electric scooter with rotatable and foldable pedals are as follows:

[0041] When in use, the left handle 412 and the right handle 413 are in a horizontal state and are locked by the locking sleeve 414; the upright rod 43 is in a vertical state and is locked by the lock buckle 45; the locking block 71 bites the shaft sleeve 5, and since the shaft sleeve 5 is relatively fixed to the front frame 11 and the rear frame 21, the locking block 71 is locked and cannot rotate at this time, and the side support block 33 sleeved on the locking block 71 is fixed in the circumferential direction and cannot rotate, so the pedal 31 connected to the side support block 33 is in a horizontal locked state.

[0042] When it is necessary to store, first, rotate the knob 721 clockwise to drive the rope driving block 722 to rotate. Since the rope connecting hole groove 7222 on the rope driving block 72 is a semi-open structure, the ropes 724 on both sides are driven to pull the connecting block 723, thereby driving the locking block 71 to disengage from the shaft sleeve 5, and the entire pedal assembly 3 can be rotated to the vertical position. Then, release the lock buckle 45, rotate the vertical rod 43 downward, and then push the locking sleeve 414 to expose the hinge between the left handle 412 and the right handle 413 and the handle connecting rod 411, and rotate the left handle 412 and the right handle 413 downward, thereby completing the folding of the pedal 31, the vertical rod 43, the left handle 412 and the right handle 413. The folded state is as follows Fig.12 shown.

[0043] When it needs to be used again, turn the pedal 31 back to the horizontal state, rotate the knob 721 counterclockwise to drive the pull rope driving block 722 to rotate, and the pull ropes 724 on both sides loosen the connecting block 723. The locking block 71 rebounds under the action of the spring 73 and bites the shaft sleeve 5 again, thereby locking the entire pedal assembly 3; turn the vertical rod 43, the left handle 412, and the right handle 413 back to the initial position, push back the locking sleeve 414, and buckle the lock buckle 45.
