[0027] Referring to Figures 1 to 4 , the present application provides an intelligent folding scooter, including a chassis 10, a seat bracket 20, and a steering handle 30. The chassis 10 includes a first chassis 101 and a second chassis 102 that can slide back and forth relative to the first chassis 101. A first electric telescopic push rod 103 is connected between the first chassis 101 and the second chassis 102. The rear end of the first electric telescopic push rod 103 is fixed to the first chassis 101, and the front end is connected to the second chassis 102. The rear end of the first electric telescopic push rod 103 is the fixed end, and the front end is the telescopic end. The second chassis 102 is provided with a front wheel seat 104. Front wheels 105 are symmetrically provided at both ends of the front wheel seat 104. A first rotating link 106 and a second rotating link 107 that are parallel to each other are connected between the front wheels 105 and the front wheel seat 104. A third rotating link 108 is rotatably connected between the corresponding ends of the first rotating link 106 and the second rotating link 107. The corresponding other ends of the first rotating link 106 and the second rotating link 107 are rotatably connected to the axle 109 of the front wheel 105. The rotating connection between the first rotating link 106 and the third rotating link 108 is also rotatably connected to the front wheel seat 104. A fourth rotating link 110 is rotatably connected between the third rotating links 108 on each side corresponding to the two front wheels 105. The rotating connection points between the third rotating link 108, the fourth rotating link 110, and the second rotating link 107 are the same. The front end of the first electric telescopic push rod 103 is connected to a transmission link 111. A fifth rotating link 112 is connected between the transmission link 111 and the first rotating link 106. The two ends of the fifth rotating link 112 are respectively rotatably connected to the transmission link 111 and the first rotating link 106.

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

[0029] Refer 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 to the second chassis 102. The bottom of the steering handle 30 protrudes out of the connecting pipe 117 and is provided with a steering connecting piece 301. The end of the steering connecting piece 301 is provided with a steering connecting rod 302. The steering connecting rod 302 is rotationally connected to the fourth rotating link 110. The front wheel seat 104 is provided with a steering limiting rod 303. One end of the steering limiting rod 303 is rotationally connected to the front wheel seat 104, and the other end is provided with a limiting kidney-shaped hole 304. The steering connecting rod 302 is inserted into the limiting kidney-shaped hole 304 and is rotationally connected to the fourth rotating link 110. The steering connecting rod 302 can rotate left and right in the limiting kidney-shaped hole 304, and the limiting kidney-shaped hole 304 limits the left and right rotation angles of the steering connecting rod 302.

[0030] Refer to Figure 4 , Figure 11 , Figure 12 , in the intelligent folding scooter of the present application, the electric unfolding and retraction of the front wheel and the process of the left and right turning of the steering handle are as follows:

[0031] When the front wheel 105 is electrically unfolded, the first electric telescopic push rod 103 is activated, and its front end extends forward. At this time, the sliding pin 114 gradually slides from the front end to the rear end of the sliding kidney-shaped groove 113. The forward extension of the front end of the first electric telescopic push rod 103 drives the transmission link 111 to move forward. The transmission link 111 drives the fifth rotating link 112 to move forward. The fifth rotating link 112 drives the first rotating link 106 to move forward, thereby driving the front wheel 105 to unfold outward. During the unfolding process of the front wheel 105, it always faces the front of the scooter. When the front wheel 105 is completely unfolded, the sliding pin 114 synchronously slides to the rear end of the sliding kidney-shaped groove 113. At this time, the first electric telescopic push rod 103 continues to extend forward, and the rear end of the sliding kidney-shaped groove 113 pushes the sliding pin 114 forward. The front end of the first electric telescopic push rod 103 drives the second chassis 102 to extend forward relative to the first chassis 101. Thus, the entire unfolding process of the front wheel 105 ends;

[0032] When the front wheel 105 is electrically retracted, the first electric telescopic push rod 103 is activated, and its front end retracts backward. At this time, the sliding pin 114 gradually slides forward from the rear end of the sliding waist-shaped groove 113. The backward retraction of the front end of the first electric telescopic push rod 103 drives the transmission connecting rod 111 to move backward, 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, thereby driving the front wheel 105 to retract inward. During the retraction process of the front wheel 105, it always faces the front of the scooter. After the front wheel 105 is completely retracted, the sliding pin 114 synchronously slides 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 sliding waist-shaped groove 113 pushes the sliding pin 114 backward. 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, and thus the entire retraction process of the front wheel 105 ends;

[0033] When turning left and right, the left and right rotation of the steering handle 30 drives the steering connection member 301 and the steering connecting rod 302 to rotate left and right. The steering connecting rod 302 drives the fourth rotating connecting rod 110 to rotate left and right, and the fourth rotating connecting rod 110 drives the second rotating connecting rod 107 to rotate left and right, thereby driving the two front wheels 105 to turn left and right.

[0034] Refer to Figures 9 to 11 , there is a rear wheel 118 and a drive motor 119 at the rear of the first chassis 101. The drive motor 119 is connected to the two rear wheels 118 and provides driving power for them. The seat bracket 20 is located above the first chassis 101. There are a connecting rod 40 and a second electric telescopic push rod 401 between the seat bracket 20 and the first chassis 101. The number of the connecting rods 40 is 2 and they are symmetrically arranged on both sides of the seat bracket 20 and the first chassis 101. The upper end of the connecting rod 40 is hinged to the rear part of the seat bracket 20, the lower end of the connecting rod 40 is hinged to the front part of the first chassis 101, the upper end of the second electric telescopic push rod 401 is hinged to the front part of the seat bracket 20, and the lower end of the second electric telescopic push rod 401 is hinged to the rear part of the first chassis 101. The seat bracket 20 can be automatically lifted upward and automatically lowered downward under the drive of the second electric telescopic push rod 401. There is also a fixing member 402 fixedly connected between the two connecting rods 40, and the two connecting rods 40 are kept moving synchronously through the fixing member 402.

[0035] The lower end of the connecting rod 40 includes a first limiting surface 403 and a first rotating surface 404. The first limiting surface 403 is planar, and the first rotating surface 404 is arc-shaped. The upper end of the connecting rod 40 includes a second limiting surface 405 and a second rotating surface 406. The second limiting surface 405 is planar, and the second rotating surface 406 is arc-shaped. The first limiting surface 403 is located on the front side of the first rotating surface 404, and the second rotating surface 406 is located on the front side of the second limiting surface 405. During the upward and downward movement of the seat bracket 20, the first rotating surface 404 contacts the first chassis 101, and the second rotating surface 406 contacts the seat bracket 20 to ensure the normal rotation of the connecting rod 40. After the upward movement of the seat bracket 20 ends, the first limiting surface 403 contacts the first chassis 101, and the second limiting surface 405 contacts the seat bracket 20 to limit the connecting rod 40 and prevent excessive rotation.

[0036] Refer to Figure 1 and Figure 13 , a backrest bracket 201 is provided on the rear side of the seat bracket 20, and the bottom of the backrest bracket 201 is hinged to the rear part of the seat bracket 20; the handle assembly 30 includes a first connecting section 305 and a second connecting section 306. The first connecting section 305 is rotatably 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 hinged to the first connecting section 305. The second connecting section 306 can be folded backward towards the rear of the scooter. Specifically, the folding and fixing of the second connecting section 306 and the first connecting section 305 are realized through a quick-release connector 307.
