[0029] like Figure 3 As shown, the front link 61 is arranged on the front seat 1 along the up-down direction. The rear link 62 is arranged between the front link 61 and the rear seat 2 along the up-down direction. The first upper link 63 is arranged between the rear link 62 and the front link 61 along the front-back direction, and the rear end 632 of the first upper link 63 is pivoted on the top end 621 of the rear link 62. The second upper link 64 is arranged between the first upper link 63 and the front link 61 along the front-back direction, and the rear end 642 of the second upper link 64 is pivoted on the front end 631 of the first upper link 63, and the front end 641 of the second upper link 64 is pivoted on the top end 611 of the front link 61.

[0030] The lower link 65 is disposed between the rear link 62 and the front link 61 along the front and rear directions, and is located below the first upper link 63 and the second upper link 64. The rear end 652 of the lower link 65 is pivoted on the bottom end 622 of the rear link 62, and the front end 651 of the lower link 65 is pivoted on the bottom end 612 of the front link 61. The front end 511 of the push rod 51 of the linear brake 5 is pivoted on the top end 621 of the rear link 62.

[0031] The base 66 is disposed between the front link 61 and the rear seat 2, the bottom end 622 of the rear link 62 is pivoted on the bottom end 661 of the base 66, and the rear end 652 of the lower link 65 is pivoted on the bottom end 661 of the base 66. The rear support arm 67 is disposed between the rear seat 2 and the base 66 along the front and rear directions, the rear end 672 of the rear support arm 67 is fixed on the rear seat 2, the base 66 is fixed on the front end 671 of the rear support arm 67, and a travel groove 673 is provided on the rear support arm 67.

[0032] like Figure 3 and Figure 4 As shown, the rear end 682 of the lower pull rod 68 is slidably disposed in the travel groove 673, and the front end 681 of the lower pull rod 68 is pivoted on the rear end 642 of the second upper connecting rod 64. The top end 691 of the upper pull rod 69 is pivoted on the bracket assembly 7, and the bottom end 692 of the upper pull rod 69 is pivoted on the rear end 682 of the lower pull rod 68.

[0033] In a feasible embodiment, the support assembly 7 can be provided in plural numbers and respectively disposed on both sides of the rear seat 2 . The support assembly 7 includes a connecting arm 71 , a front support rod 72 and a rear support rod 73 .

[0034] like Figure 3 As shown, the front end 711 of the linkage arm 71 is pivoted at the front end 41 of the bottom of the seat 4. The front support rod 72 is pivoted between the front end 21 of the rear seat 2 and the front end 711 of the linkage arm 71, and the top end 691 of the upper pull rod 69 is pivoted at the middle part of the front support rod 72. The rear support rod 73 is pivoted between the rear end 22 of the rear seat 2 and the rear end 712 of the linkage arm 71, and the front support rod 72 and the rear support rod 73 are parallel to each other.

[0035] See also Figures 3 to 6 When in use, the battery 9 can supply power to drive the linear brake 5, so that the push rod 51 of the linear brake 5 drives the top end 621 of the rear connecting rod 62 to swing toward the front seat 1 (such as Figure 3 and Figure 4 ), to drive the first upper link 63 and the second upper link 64 to push the top end 611 of the front link 61, and the second upper link 64 amplifies the actuation and folding angle, so as to cause the bottom end 612 of the front link 61 to drive the lower link 65 to push the bottom end 622 of the rear link 62 toward the rear seat 2 (as shown in FIG. Figure 5 and Figure 6 As shown in FIG. 1 , the rear end 642 of the second upper connecting rod 64 and the rear end 652 of the lower connecting rod 65 are swung upward, so that the front seat 1 is folded toward the rear seat 2.

[0036] At the same time, the push rod 51 of the linear brake 5 also drives the rear end 682 of the lower rod 68 to move along the travel groove 673 toward the front seat 1 via the rear end 642 of the second upper link 64, so as to drive the upper link 69 to drive the support assembly 7, the front support rod 72 and the seat 4 to swing toward the front seat 1, so that the rear seat 2 is folded toward the front seat 1. During this period, the bottom end 622 of the rear link 62 and the bottom end 612 of the front link 61 can serve as auxiliary support points of the folding link assembly 6, so that the front link 61, the first upper link 63, the second upper link 64 and the rear support arm 67 are folded upward.

[0037] As shown in the above figure, it can be understood that the utility model uses the connecting rod assembly 6 to form the pedal of the scooter, and uses the connecting rod assembly 6 to achieve the function of lifting and folding the front seat 1 and the rear seat 2, so that the connecting rod assembly 6 and the seat 4 are filled to the space above the scooter, and the scooter can be folded simply and quickly, which is convenient to operate; moreover, when the scooter is folded, the distance between the front seat 1 and the rear seat 2 is reduced to adjust the overall length of the scooter, reduce the area occupied by the scooter, and reduce the space occupied by the scooter after being stored. In addition, when the scooter is folded, the front wheels 11 and the rear wheels 23 of the scooter are kept horizontally in contact with the ground, so that the user can pull the steering rod 3 to drag the scooter, and the scooter can also be prevented from tipping over. Furthermore, when the scooter is folded, the battery 9 will swing toward the rear of the scooter along with the rear seat 2 and the rear support arm 67, and the seat 4 will automatically lift up, making it convenient for the user to replace the battery 9 and carry the battery 9 to a charging station for charging, thereby preventing the battery 9 from being stolen.

[0038] When the push rod 51 of the linear brake 5 drives the top end 621 of the rear link 62 in the reverse direction to swing toward the rear seat 2, the rear link 62 links the first upper link 63, the second upper link 64, the front link 61, the lower link 65, the rear support arm 67, the lower pull rod 68, the upper pull rod 69 and the bracket assembly 7 to reset in the reverse direction. At this time, the first upper link 63, the second upper link 64 and the rear support arm 67 are in a horizontal state, so that the user can ride the scooter.

[0039] See also Figure 2 and Figure 3 In another feasible embodiment, a guide groove 24 extending toward the front seat 1 may be provided at the bottom of the rear seat 2, and the linear brake 5 is slidably disposed in the guide groove 24. A positioning hole 53 is provided at the rear end 52 of the linear brake 5. A handle 25 is pivotally disposed at the bottom of the rear seat 2, and a fixing pin 26 is provided on the handle 25. The fixing pin 26 is inserted into the positioning hole 53 at the rear end 52 of the linear brake 5 to fix the linear brake 5 at the bottom of the rear seat 2.

[0040] See also Figure 7 When the scooter is unfolded, when the battery 9 is out of power or the linear brake 5 fails, the user can manually pull the handle 25 to drive the fixing pin 26 to disengage from the positioning hole 53 at the rear end 52 of the linear brake 5, so as to release the linear brake 5 to slide in the guide groove 24. In this way, the user can manually lift the connecting rod assembly 6 upwards, during which the push rod 51 of the linear brake 5 will be driven by the connecting rod assembly 6 to cause the linear brake 5 to slide along the guide groove 24 toward the front seat 1, thereby achieving the manual folding function.

[0041] In addition, the front wheel 11 can be disposed at the bottom of the front seat 1 using an independent suspension structure, and the rear wheel 23 can also be disposed at the bottom of the rear seat 2 using an independent suspension structure to enhance the shock absorption capability of the scooter.

[0042] The above-mentioned embodiment description and drawings only illustrate the preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model; any examples that are similar or identical to the purpose, structure, device, feature, etc. of the present utility model should fall within the patent scope of the present utility model.
