DETAILED DESCRIPTION

[0033] The specific embodiment of the utility model is further described below in combination with the drawings and examples.

[0034] Referring to Figure 1 The utility model relates to a kind of scooter, including chassis assembly 1, seat assembly 2 and the folding assembly 3 between the two, folding assembly 3 can drive seat assembly 2 relative to chassis assembly 1 close or unfold.

[0035] Referring to Figure 1The chassis assembly 1 includes a chassis frame 11, a front wheel 12 and a rear wheel 13; the seat assembly 2 includes a seat back 23, a seat 21 and a seat back pole 22 that are pivotally connected to each other; the folding assembly 3 mainly includes a main support pole 31, an auxiliary support pole 32 and a connecting rod 33.

[0036] See Figures 1-2 When the mobility scooter is in the unfolded state, the main support rod 31 is tilted on the chassis assembly 1, and its two ends are respectively pivotally connected to the chassis frame 11 and the pivot seat 211 at the bottom of the seat 21. The lower end of the auxiliary support rod 32 is pivotally connected to another point of the chassis frame 11. The connecting rod 33 is pivotally connected to the central axis a at the intersection of the main support rod 31 and the connecting rod 33. At the same time, the two ends of the connecting rod 33 are also pivotally connected to the upper end of the auxiliary support rod 32 and the lower end of the backrest rod 22, respectively. While the lower end of the backrest rod 22 is pivotally connected to the upper end of the connecting rod 33, it is also pivotally connected to the rear of the seat 21.

[0037] At this time, the backrest rod 22, the seat 21, the main support rod 31, and the connecting rod 33 form a four-bar linkage mechanism; the main support rod 31, the connecting rod 33, the auxiliary support rod 32, and the chassis frame 11 form another four-bar linkage mechanism. The two four-bar linkage mechanisms are basically symmetrical and linked relative to the central axis a.

[0038] See Figures 1-2 The upper end of the backrest rod 22 is an extension section, and the backrest 23 is fixed on the extension section; the folding assembly 3 also includes an electric push rod 34 whose two ends are respectively rotatably connected to the main support rod 31 and the chassis frame 11, and the three are supported in a triangular shape.

[0039] As the driving and limiting components of the folding assembly 3, the electric push rod 34 locks the various structures relative to each other when it is stationary; when the electric push rod 34 extends or retracts, the main support rod 31 can move the seat 21 and the backrest 23 to fold or unfold relative to the chassis frame 11.

[0040] See Figures 1-2 When the mobility scooter is in the unfolded state, the electric push rod 34 is in the maximum size static state, and the main support rod 31 and the chassis frame 11, which are triangularly fixed to the electric push rod 34, are unfolded and fixed relative to each other. The backrest 23 is unfolded relative to the seat 21, and the seat assembly 2 is unfolded and fixed relative to the chassis frame 11 at the highest position.

[0041] See Figure 3 When the mobility scooter is folded, the electric push rod 34 is shorter in size than when it is unfolded. The electric push rod 34 pulls the support rod 31, causing the folding assembly 3 to tilt forward as a whole. The linkage rod 33 rotates along the central axis a and pushes the lower end of the backrest rod 22 away from the rear of the seat 21. The backrest 23 moves closer to the seat 21, and the seat assembly 2 moves towards the chassis frame 11.

[0042] See Figure 4, the scooter is in the folded state, the electric push rod 34 is in the minimum size static state, the support main rod 31 is fixed relative to the chassis frame 11, the chair back 23 is folded to the seat 21 and stacked above the chassis frame 11, and the folding assembly 3 is folded between the seat 21 and the chassis frame 11.

[0043] Referring to Figures 5-6 , the seat assembly 2 further comprises an armrest 24, the armrest 24 is rotationally connected with the seat 21, and a limiting groove 241 and a positioning column 242 are arranged on the armrest 24, the limiting groove 241 can enable the armrest 24 to rotate within a preset range relative to the seat 21. A reasonable angle interval of the preset range is 0°-90°.

[0044] The seat assembly 2 further comprises a clamping hook 25 rotationally connected with the seat 21, the clamping hook 25 is provided with a locking portion 251 for locking the armrest positioning column 242 and a rotating groove 252 for limiting rotation relative to the seat 21. Under the action of a torsion spring 26 arranged between the seat 21 and the clamping hook 25, the clamping hook 25 always has a tendency to rotate to the locking armrest state.

[0045] Referring to Figures 5-6 , when the armrest 24 is in the unfolded state, the armrest 24 is obliquely unfolded above the seat 21, and under the action of the torsion spring 26, the positioning column 242 is clamped into the locking portion 251 of the clamping hook 25 and is stationary, and the armrest 24 is fixed relative to the seat 21;

[0046] Referring to Figures 7-8 , the clamping hook 25 is pressed to be unlocked from the armrest positioning column 242, and the armrest 24 can rotate freely within the preset range relative to the seat 21 under the action of the limiting groove 241, the armrest 24 is rotated rearward relative to the seat 21, and the armrest 24 is in the folded state.

[0047] When the armrest 24 is rotated from the folded state to the unfolded state relative to the seat 21, the armrest positioning column 242 pushes the clamping hook 25 to rotate relative to the seat 21 until the armrest 24 is in the unfolded state. At this time, the clamping hook 25 is rotated and reset relative to the seat 21 under the action of the elastic force of the torsion spring 26, the positioning column 242 is automatically clamped into the locking portion 251, at this time, the locking portion 251 is locked relative to the positioning column 242, the armrest 24 is obliquely arranged above the seat 21 and is fixed relative to the seat 21.

[0048] Referring to Figure 2 , the scooter and the armrest 24 are in the unfolded state at the same time, and when viewed from the side, the armrest 24 and the support main rod 31 have similar oblique angles and are similar to an integral structure, which is simple and beautiful. In addition, the armrest 24 can be folded relative to the seat 21 at any time, which further improves the operation experience of the user while reducing the folding volume of the scooter, and the user can get on and off the scooter from any side.

[0049] The application discloses a scooter, which is simple in structure, stable in operation, low in production cost, convenient to operate, small in volume in a folded state, convenient to store and carry, and capable of providing better experience for users.

[0050] In the above embodiments, the utility model is only described exemplarily, but those skilled in the art can make various modifications to the utility model without departing from the spirit and scope of the utility model after reading the patent application, and the modifications shall also be included in the protection scope of the utility model.
