DETAILED DESCRIPTION

[0017] In order to make the above features and advantages of the present invention more easily understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0018] refer to Figures 1 to 10 An electric scooter foldable into a seat comprises a pair of pedal connecting plates 10 arranged side by side, the front parts of the pair of pedal connecting plates are rotatably connected to both sides of a first vertical axis 20 and can be swung outwards 90°, the rear ends of the pair of pedal connecting plates are rotatably connected to front pedals 30 that can be swung inwards 90°, the rear ends of the front pedals are rotatably connected to rear pedals 40 that can be swung down 180° and fit on the bottom surface of the front pedals, the rear ends of the rear pedals are provided with rear wheels 50, the lower end of the first vertical axis is provided with a front wheel assembly 60 that can be swung back 90°, the upper end of the first vertical axis is provided with an operating assembly 70 that can be swung down 90°, and the upper end of the first vertical axis is provided with a seat plate 80 that can be swung down 180° vertically on the front side. A three-point supported seat is formed by folding, and the seat plate serves as a support plate for users to sit on.

[0019] In this embodiment, the front end of the pedal connecting plate is rotatably connected to the first vertical axis via the shaft sleeve 11, and the front end surfaces of a pair of pedal connecting plates abut against each other after the rear end of the pedal connecting plate is rotated 90° outward around the first vertical axis to limit the rotation.

[0020] In this embodiment, the rear ends of the pedal connecting plates are rotatably connected to the front pedals via the second vertical shaft 12 and are provided with a 90° rotation limiting structure; the two second vertical shafts are arranged up and down when a pair of pedal connecting plates are arranged side by side.

[0021] In this embodiment, the rotation limit structure includes a first horizontal rotating plate 13 fixed at the rear end of the pedal connecting plate, a second horizontal rotating plate 31 is fixed to the front end of the front pedal, the second vertical axis passes through the first horizontal rotating plate and the second horizontal rotating plate, the upper end surface of the first horizontal rotating plate is provided with a first limit block 14 in a fan shape (arc 135°), and the lower end surface of the second horizontal rotating plate is provided with a second limit block 32 in a fan shape (arc 135°). In the unfolded state, one side surface of the second limit block abuts against one side surface of the first limit block. When the current pedal swings inward 90°, the other side surface of the second limit block abuts against the other side surface of the first limit block to form a swing limit.

[0022] In this embodiment, the rear lower portion of the front pedal is rotatably connected to the front end of the rear pedal via the transverse rotation shaft 33, and the rear wheel is installed on the rear outer side of the rear pedal. By installing the transverse rotation shaft at the rear lower portion of the front pedal, after the front and rear pedals are unfolded, the rear upper portion of the front pedal abuts against the front upper portion of the rear pedal and cannot be turned upward, which will not affect the rigidity of the pedals. The rear pedal can only be turned downward around the transverse rotation shaft and folded 180 degrees.

[0023] In this embodiment, the front wheel assembly includes an inverted U-shaped front wheel frame 61, in which a front wheel 62 is installed, and the front wheel can be a motor wheel. The upper end of the front wheel frame is connected to the lower end of the first vertical axis through a transversely arranged rotating shaft assembly, and an anti-flip structure is arranged on the rotating shaft assembly.

[0024] Specifically, the rotating shaft assembly includes three first rotating plates 21 fixed at the lower end of the first rotating shaft, two second rotating plates 63 inserted between two adjacent first rotating plates are fixed at the upper end of the front wheel frame, and the first transverse shaft rod 65 passes through the first rotating plate and the second rotating plate in sequence and is fixed to the first rotating plate; the anti-flipping structure is a first limiting latch 64 arranged beside the first transverse shaft rod and passing through the first rotating plate and the second rotating plate, and the first limiting latch is provided with a spring bead and other structures to prevent it from falling off the first rotating plate. When the first limiting latch is inserted, the front wheel frame cannot rotate around the first vertical axis. When folding is required, the first limiting latch is pulled outward to realize the front wheel frame flipping and folding backward and upward.

[0025] In this embodiment, the operating assembly includes an operating rod 71, a fixing block 72 is fixed to the upper end of the operating rod, and handles 73 are respectively provided on both sides of the fixing block. The handles are connected to the fixing block via a spherical shaft 74 and can be flipped downward by 90°.

[0026] In this embodiment, three third rotating plates 22 are fixed to the upper end of the first vertical axis, two fourth rotating plates 75 for inserting between two adjacent third rotating plates are fixed to the lower end of the operating rod, a second transverse shaft rod 76 passes through the third rotating plate and the fourth rotating plate in sequence and is fixed to the third rotating plate, and a second limit pin 77 passing through the third rotating plate and the fourth rotating plate is arranged beside the second transverse shaft rod. When the second limit pin is inserted, the operating rod cannot rotate around the first vertical axis. When folding is required, the first limit pin is pulled outward to realize the operation rod flipping and folding backward and downward. The second limit pin is provided with a spring bead and other structures to prevent it from falling off the third rotating plate.

[0027] In this embodiment, avoidance slots 78 for the ball head axis to flip downward are provided on both sides of the fixed block. A limit pin is provided in the avoidance slot to prevent the handle from bending outward when unfolded. After pulling out the limit pin, the handle can be flipped downward 90° for folding.

[0028] In this embodiment, a connection block 23 is fixed to the upper front end of the first vertical axis, and the front end of the connection block forms a rotation connection with rotation damping with the lower end of the seat plate via the third transverse rotation axis 24. In a normal state, the upper end of the seat plate faces upward and is close to the operating rod. When it needs to be folded into a seat, the seat plate flips downward around the third transverse rotation axis to allow the user to sit.

[0029] In this embodiment, the battery of the electric scooter can be arranged in the front pedal and the rear pedal.

[0030] When folding, fold in the following order: 1. First, turn the rear pedal downward 180° and fit it on the bottom surface of the front pedal; 2. Turn the handle downward 90° and place it close to the operating lever; 3. Turn the pair of pedal connecting plates outward 90° around the first vertical axis, so that the front ends of the pair of pedal connections are in contact with each other; 4. Turn the front pedal and the rear pedal inward 90°, so that the pedal connecting plate forms a 90° angle with the front pedal; 5. Flip the operating lever backward 90° to form a 90° angle with the first vertical axis, and flip the front wheel assembly backward and upward 90°; 6. Flip the seat plate downward 180°, and finally flip the entire folded device another 90°, so that the rear end of the front pedal and the connecting block are supported on the ground, forming a three-point supported seat. It can provide a temporary resting place for users when commuting or in other situations.
