[0028] Referring to Figures 5 to 7The front end of the first electric telescopic push rod 103 is provided with a sliding waist-shaped groove 113 and a sliding tip 114 at the connection position with the second chassis 102. The second chassis 102 is provided with a connecting seat 115 for mounting the sliding tip 114. The sliding tip 114 penetrates through the connecting seat 115 and is inserted into the sliding waist-shaped groove 113. The sliding tip 114 can slide back and forth between the front end and the rear end of the sliding waist-shaped groove 113. The wheel shaft 109 of the front wheel 105 is provided with a wheel shaft connecting piece 116 which is parallel to the third rotating connecting rod 108 and is rotationally connected with the first rotating connecting rod 106 and the second rotating connecting rod 107.

[0029] Referring to Figures 2 to 4 , Figure 8 , the second chassis 102 is provided with a vertically arranged connecting pipe 117. The steering handle 30 is inserted into the connecting pipe 117 and is rotationally connected with the second chassis 102. The steering handle 30 is provided with a steering connecting piece 301 which protrudes out of the connecting pipe 117 at the bottom. The end of the steering connecting piece 301 is provided with a steering connecting rod 302 which is rotationally connected with the fourth rotating connecting rod 110. The front wheel seat 104 is provided with a steering limiting rod 303 which is rotationally connected with the front wheel seat 104 at one end and is provided with a limiting waist-shaped hole 304 at the other end. The steering connecting rod 302 is inserted into the limiting waist-shaped hole 304 and is rotationally connected with the fourth rotating connecting rod 110. The steering connecting rod 302 can rotate left and right in the limiting waist-shaped hole 304. The limiting waist-shaped hole 304 limits the left and right rotation angle of the steering connecting rod 302.

[0030] Referring to Figure 4 , Figure 11 , Figure 12 , the process of the electric expansion and contraction of the front wheel and the left and right steering of the steering handle in the intelligent folding scooter of the present application is as follows:

[0031] When the front wheel 105 is electrically expanded, the first electric telescopic push rod 103 is started. The front end thereof is stretched forward. At this time, the sliding tip 114 gradually slides from the front end to the rear end of the sliding waist-shaped groove 113. The forward stretching of the front end of the first electric telescopic push rod 103 drives the transmission connecting rod 111 to move forward. The transmission connecting rod 111 drives the fifth rotating connecting rod 112 to move forward. The fifth rotating connecting rod 112 drives the first rotating connecting rod 106 to move forward, thereby driving the front wheel 105 to expand outward. The front wheel 105 always faces forward during the expansion process. When the front wheel 105 is completely expanded, the sliding tip 114 is synchronously slid to the rear end of the sliding waist-shaped groove 113. At this time, the first electric telescopic push rod 103 continues to stretch forward. The rear end of the sliding waist-shaped groove 113 holds the sliding tip 114 forward. The front end of the first electric telescopic push rod 103 drives the second chassis 102 to stretch forward relative to the first chassis 101. Thus, the entire expansion process of the front wheel 105 is completed.

[0032] When the front wheels 105 are electrically retracted, the first electric telescopic push rod 103 is activated, and the front end thereof is retracted backward. At this time, the sliding tip 114 gradually slides from the rear end to the front end of the sliding waist-shaped groove 113. The retraction of the front end of the first electric telescopic push rod 103 drives the transmission connecting rod 111 to move backward, and the transmission connecting rod 111 drives the fifth rotating connecting rod 112 to move backward, and the fifth rotating connecting rod 112 drives the first rotating connecting rod 106 to move backward, and further drives the front wheels 105 to retract inward. The front wheels 105 always face the front of the scooter during the retraction process. When the front wheels 105 are completely retracted, the sliding tip 114 is synchronously slid to the front end of the sliding waist-shaped groove 113. At this time, the first electric telescopic push rod 103 continues to retract backward, and the front end of the first electric telescopic push rod 103 drives the second chassis 102 to retract backward relative to the first chassis 101. Thus, the entire retraction process of the front wheels 105 is completed.

[0033] When turning left or right, the steering handle 30 is turned left or right, driving the steering connecting piece 301 and the steering connecting rod 302 to turn left or right. The steering connecting rod 302 drives the fourth rotating connecting rod 110 to turn left or right, and the fourth rotating connecting rod 110 drives the second rotating connecting rod 107 to turn left or right, and further drives the two front wheels 105 to turn left or right.

[0034] Referring to Figures 9 to 11 The first chassis 101 is provided with rear wheels 118 and a drive motor 119 at the rear portion thereof. The drive motor 119 is connected with the two rear wheels 118 and provides driving power for the two rear wheels 118. The seat support 20 is located at the upper portion of the first chassis 101. The seat support 20 and the first chassis 101 are provided with connecting rods 40 and a second electric telescopic push rod 401 therebetween. The number of the connecting rods 40 is two, and the two connecting rods 40 are symmetrically arranged at the two sides of the seat support 20 and the first chassis 101. The upper ends of the connecting rods 40 are hingedly connected with the rear portion of the seat support 20, and the lower ends of the connecting rods 40 are hingedly connected with the front portion of the first chassis 101. The upper end of the second electric telescopic push rod 401 is hingedly connected with the front portion of the seat support 20, and the lower end of the second electric telescopic push rod 401 is hingedly connected with the rear portion of the first chassis 101. The seat support 20 can be automatically lifted upward and automatically lowered downward under the driving of the second electric telescopic push rod 401. The two connecting rods 40 are further fixedly connected with a fixing piece 402, so that the two connecting rods 40 keep synchronous movement through the fixing piece 402.

[0035] The lower end of the connecting rod 40 comprises a first limiting surface 403 and a first rotating surface 404, the first limiting surface 403 is flat, and the first rotating surface 404 is circular arc-shaped; the upper end of the connecting rod 40 comprises a second limiting surface 405 and a second rotating surface 406, the second limiting surface 405 is flat, and the second rotating surface 406 is circular arc-shaped; the first limiting surface 403 is located in front of the first rotating surface 404, and the second rotating surface 406 is located in front of the second limiting surface 405; during the lifting and lowering of the seat support 20, the first rotating surface 404 is in contact with the first bottom frame 101, and the second rotating surface 406 is in contact with the seat support 20, so as to ensure the normal rotation of the connecting rod 40; after the lifting of the seat support 20 is completed, the first limiting surface 403 is in contact with the first bottom frame 101, and the second limiting surface 405 is in contact with the seat support 20, so as to limit the connecting rod 40 and prevent excessive rotation.

[0036] With reference to Figure 1 and Figure 13 The rear side of the seat support 20 is provided with a backrest support 201, and the bottom of the backrest support 201 is hingedly connected to the rear part of the seat support 20; the handle assembly 30 comprises a first connecting section 305 and a second connecting section 306, the first connecting section 305 is rotationally connected to the connecting pipe 117, and the second connecting section 306 is arranged on the upper part of the first connecting section 305 and is hingedly connected to the first connecting section 305; the second connecting section 306 can be folded towards the rear side of the scooter, and specifically, the folding and fixing of the second connecting section 306 and the first connecting section 305 are realized through a quick release connecting piece 307.
