[0028] As shown in FIGs. 1 to 3, the foldable mobility scooter 100 of the present invention includes a chassis 1, a first support rod 2, a second support rod 3, a seat base 4, a swing link 5, and a latch fastener 6. The first support rod 2, the second support rod 3, the swing link 5, and the latch fastener 6 are symmetrically arranged on both sides of the chassis 1 to collectively support the seat base 4. The chassis I is a fixed frame formed by connecting and securing multiple rods. Front wheels 11 are arranged on opposite sides of the front end of the chassis 1 and rear wheels 12 are arranged on opposite sides of the rear end of the chassis 1.
[0029] A lower end of the first support rod 2 is pivotally connected to the chassis 1 at a pivot shaft a, and an upper end of the first support rod 2 is movably connected to a rear end of the seat base 4. A backrest plate 41 is pivotally connected to the rear end of the seat base 4. The second support rod 3 and the first support rod 2 are arranged crosswise and pivotally connected to each other at their middle parts via a pivot shaft b. An upper end of the second support rod 3 is pivotally connected to a front end of the seat base 4 at a pivot shaft c. A lower end of the second support rod 3 is pivotally connected to one end of the swing link 5 at a pivot shaft d, which is located rearward of the pivot shaft a. The other end of the swing link 5 is pivotally connected to the chassis 1 at a pivot shaft e. The latch fastener 6 is arranged on the second support rod 3 and can be engaged with and locked to the chassis 1 when the frame is unfolded.
[0030] Referring to FIG. 3, the foldable mobility scooter 100 further includes a third support rod 7. One end of the third support rod 7 is pivotally connected to the upper end of the first support rod 2 at a pivot shaft f, and the other end is pivotally connected to the rear end of the seat base 4 at a pivot shaft g. By providing the third support rod 7, an upper section of the first support rod 2, an upper section of the second support rod 3, the seat base 4, and the third support rod 7 form a deformable quadrilateral structure, thereby enabling deformable folding. The structure is simple and the operation is convenient.
[0031] As shown in FIG. 3, the latch fastener 6 is pivotally connected to the lower end of the second support rod 3. Specifically, the pivot shaft for the latch fastener 6 on the second support rod 3 is coaxial with the pivot shaft d connecting the second support rod 3 and the swing link 5. One end of the latch fastener 6 is provided with a hook 61, and an outer side of the chassis 1 is provided with an engagement part 13 for engaging with the hook 61. Specifically, the engagement part 13 is a pin, which engages with the hook 61. This facilitates the engagement between the latch fastener 6 and the second support rod 3, improves the convenience of unfolding and folding operations, and enhances stability and safety during use. Furthermore, an operating rod 130 is connected between the two latch fasteners 6 on opposite sides of the chassis I. By operating the operating rod 130, the latch fasteners 6 can be driven simultaneously to lock or unlock, thereby improving the using convenience.
[0032] Referring to FIGs. 2 and 4, the foldable mobility scooter 100 further includes a reset member 8 arranged between the second support rod 3 and the latch fastener 6 to keep the latch fastener 6 engaged with the chassis 1. The reset member 8 is a tension spring. In such a way, the latch fastener 6 is prevented from accidentally disengaging from the chassis 1, thereby avoiding accidental folding of the frame, and improving stability and safety during use. Specifically, the lower end of the second support rod 3 is fixedly provided with a connection base 31, and the reset member 8 is connected to the connection base 31. Therefore, a stable connection between the reset member 8, the second support rod 3, and the latch fastener 6 is ensured, thereby preventing the interference.
[0033] Referring to FIGs. 2 and 4, the foldable mobility scooter 100 further includes an elastic member 9 arranged between the swing link 5 and the chassis 1 to keep the swing link 5 in the position it occupies when the scooter frame is unfolded. The elastic member 9 is a tension spring.

These configurations can prevent one or more of the first support rod 2, the second support rod 3, and the swing link 5 from swinging accidentally, thereby avoiding accidental folding of the frame, and improving the stability and safety of the frame when unfolded.
[0034] As shown in FIGs. 1 and 3, the foldable mobility scooter 100 further includes a steering rod 10, a rotating base 110, and a gas spring 120. The steering rod 10 is arranged at the front end of the chassis 1. The rotating base 110 is rotatably arranged at the front end of the chassis 1. A lower end of the steering rod 10 is pivotally connected to the front end of the rotating base 110. A lower end of the gas spring 120 is pivotally connected to the rear end of the rotating base 110, and an upper end of the gas spring 120 is pivotally connected to a connecting lug 101 on the steering rod 10. By providing the gas spring 120 and utilizing its extendable and retractable characteristics, the steering rod 10, the rotating base 110, and the gas spring 120 form a variable triangular structure, thereby allowing the steering rod 10 to move close to the chassis 1 to achieve folding. In such a way, the volume occupied by the frame is reduced and the convenience of storage and transportation are improved. [0028] Combining with FIGs. 3, 5, and 6, when folding the foldable mobility scooter 100, the operating rod 130 is first pulled to drive the latch fastener 6 to rotate about the pivot shaft h, causing the hook 61 of the latch fastener 6 to disengage from the pin 13. At this point, the second support rod 3 and the chassis 1 are unlocked. Then, the operating rod 130 is pulled backward, causing the swing link 5 to swing backward about the pivot shaft e, while the lower end of the second support rod 3 also swings backward. Consequently, the first support rod 2 and the second support rod 3 move close to the chassis 1. Simultaneously, the first support rod 2 drives the third support rod 7 to swing. Under the combined action of the first support rod 2 and the third support rod 7, the seat base 4 moves close to the chassis 1. When the first support rod 2, the second support rod 3, and the seat base 4 are completely folded against the chassis 1, the backrest plate 41 is pushed on the seat base 4 to fold toward the seat base 4. Finally, by pressing the gas spring 120, the gas spring 120 is retracted, causing the steering rod 10 to move close to the chassis I for folding. At this point, the foldable mobility scooter 100 is completely folded. When unfolding is required, the above operations are reversed, to finally engage the latch fastener 6 with the pin to unfold the foldable mobility scooter 100 into a locked state.
[0035] Compared with the prior art, in the present invention, the first support rod 2 and the second support rod 3 are arranged on the chassis 1, the first support rod 2 and the second support rod 3 are arranged in a crossed manner and are pivotally connected to each other, the seat base 4 is positioned between the first support rod 2 and the second support rod 3, and further the swing link 5 is pivotally connected between the chassis 1 and the second support rod 3, thus the first support rod 2 and the second support rod 3 can be movably unfolded or folded relative to the chassis 1. In the unfolded state, the first support rod 2 and the second support rod 3 support the seat base 4, and the latch fastener 6 is locked to the chassis 1, bringing the entire frame into a stable unfolded state for use. In the folded state, the first support rod 2 and the second support rod 3 move close to the chassis 1, to achieve a folded state. This effectively reduces the volume of the entire frame, thereby facilitating storage and transportation. Furthermore, the folding process is simple and convenient, which requires only controlling one of the first support rod 2, the second support rod 3, or the swing link 5. Additionally, the entire frame has fewer components than existing foldable mobility scooters, making the assembly simpler and thus the cost lower. By this token, it is conducive to widespread adoption and the convenience for the elderly is improved.
[0036] Furthermore, in another embodiment, the rear end of the seat base 4 is provided with a sliding slot along a front-rear direction, and the upper end of the first support rod 2 is slidably arranged in the sliding slot via a sliding shaft. By providing the sliding slot and having the first support rod 2 slidably cooperate with the sliding slot, the first support rod 2, the second support rod 3, and the seat base 4 form a variable triangular structure, thereby enabling folding. The structure is simple and the operation is convenient.
[0037] The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
