[0001] The present application relates to the field of mobility scooters, and in particular, to a folding seat of a mobility scooter and a folding mobility scooter. Background Art

[0002] At present, with the increasing attention paid by society to barrier-free travel, a wide variety of mobility scooters have emerged on the market for people with limited mobility, such as patients, the elderly and the disabled, greatly improving the quality of life and freedom of travel for these groups. However, although these mobility scooters are designed to meet diverse travel needs, their relatively large size has caused a series of challenges in actual use.

[0003] First, the inconvenience of carrying has become a significant problem. Many mobility scooters are difficult for users to carry on public transportation or carry manually over short distances due to their complex structure and heavy weight. This is particularly inconvenient when users need to frequently change travel modes or face obstacles such as stairs and steps.

[0004] Secondly, the storage problem also needs to be solved urgently. For families with limited living space, the storage of large mobility scooters has become a big challenge. Even in public places such as hospitals and shopping malls where mobility scooters are provided, sufficient and reasonable space is needed for effective storage management to ensure the availability and maintenance efficiency of the equipment.

[0005] Furthermore, the inconvenience of transportation also limits the use of mobility scooters. When it is necessary to move across cities or long distances, the transportation of mobility scooters often becomes a major obstacle. Whether it is loaded in a private car or transported through logistics, the size and weight of the scooters add additional costs and complexity. Utility Model Content

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] Please refer to Figure 1 , Figure 1 The present application provides a first embodiment of a folding seat 2 for a mobility scooter, wherein the folding seat 2 is disposed on a vehicle frame 1, and the vehicle frame includes two frame longitudinal beams 11, two vertical beams 12 and a U-shaped beam 13, wherein the vertical beam 12 is used to connect the frame longitudinal beams 11 and the U-shaped beam 13.

[0039] Specifically, the folding seat 2 includes a first arm 21, a second arm 22, a locking mechanism and a seat mounting bracket 23; the bottom end of the first arm 21 is hinged to the bottom plane of the frame, and the top end of the first arm 21 is hinged to the seat plane; the bottom end of the second arm 22 is hinged to the plane of the vertical beam 12, and the top end of the second arm 22 is hinged to the seat plane.

[0040] When the folding seat 2 is in the folded state, the first arm 21, the second arm 22 and the seat mounting bracket 23 are placed close to the bottom plane of the frame; when the folding seat 2 is in the unfolded state, the first arm 21 and the second arm 22 are placed vertically and raise the seat mounting bracket 23, and the second arm 22 is fixed by the locking mechanism.

[0041] In the embodiment of the present application, the folding seat 2 can be folded to near the bottom plane of the frame when not in use, which significantly reduces the total volume and occupied space of the vehicle, is convenient for storage and carrying, and is particularly suitable for urban travel, public transportation connections or parking in limited spaces. The compact form after folding makes the vehicle more flexible and convenient for passing through narrow passages or entering spaces such as elevators. Through the dual support of the first arm 21 and the second arm 22, and the fixing effect of the locking mechanism, the folding seat 2 can provide stable and strong support in the unfolded state, ensuring the safety and comfort of passengers. The folding and unfolding process is simple and fast, and the user only needs to perform simple operations (such as releasing the locking mechanism) to achieve the conversion of the seat, which improves the convenience and efficiency of use. This design reduces the time for users to adjust the seat before and after use, making the scooter more in line with the fast-paced urban lifestyle.

[0042] The folding seat 2 of this embodiment includes two first arms 21; the bottom ends of the first arms 21 are hinged to the frame longitudinal beam 11 of the frame bottom plane, and the top ends of the first arms 21 are hinged to the seat support longitudinal beam 231 of the seat mounting bracket 23. Figure 1 As shown, the two first arms 21 are symmetrically distributed on both sides of the frame.

[0043] The folding seat 2 of this embodiment includes two second arms 22; the bottom ends of the second arms 22 are hinged to the middle of the vertical beam 12, and the top ends of the second arms 22 are hinged to the seat support longitudinal beam 231 of the seat mounting bracket 23. Figure 1 As shown, the two second arms 22 are symmetrically distributed on both sides of the frame.

[0044] In some optional embodiments, the locking mechanism includes: a first limiting column 241, a second limiting column 242 and an angle fixing assembly. The first limiting column 241 is arranged at the top of the vertical beam 12, and is used to prevent the second arm 22 from continuing to rotate clockwise around its bottom end when the second arm 22 is placed vertically; the second limiting column 242 is arranged on the seat support longitudinal beam 231 of the seat mounting bracket 23, and is used to limit the angle between the second arm 22 and the seat plane to not less than a set angle; the angle fixing assembly is used to fix the angle between the second arm 22 and the seat plane to a set angle when the second arm 22 is placed vertically.

[0045] In some optional embodiments, the angle fixing assembly includes a reset rod 243, a spring 244 and a sliding groove; wherein the reset rod 243 slides in the sliding groove, one end of the spring is fixed at the spring fixing point 245, the other end of the spring is connected to the reset rod 243, and the spring 244 is used to pull the reset rod 243 to move toward the bottom end of the sliding groove; the bottom end of the sliding groove is close to the top end of the second arm 22, and the top end of the sliding groove is away from and exceeds the top end of the second arm 22. When the second arm 22 is placed vertically, the spring 244 pulls the reset rod 243 to make the reset rod 243 contact with the top end of the second arm 22.

[0046] like Figure 1 As shown, this embodiment includes two first limiting posts 241, two second limiting posts 242 and two angle fixing components, and the two first limiting posts 241, the two second limiting posts 242 and the two angle fixing components are symmetrically distributed on both sides of the frame. The top of the second arm 22 is provided with an oblique guide surface, and during the movement of the folding seat 2 from the folding state to the unfolding state, the oblique guide surface causes the reset rod 243 to move from the bottom end to the top end of the sliding groove until the folding seat 2 is fully unfolded. When the reset rod 243 reaches the top end of the sliding groove, the oblique guide surface no longer contacts the reset rod 243, and the reset rod 243 is only subjected to the pulling force of the spring 244, and the reset rod 243 returns to the bottom end of the sliding groove, thereby realizing the limiting effect on the second arm 22.

[0047] In the embodiment of the present application, when the second arm 22 is placed vertically, the spring 244 will automatically pull the reset rod 243 to move toward the bottom end of the sliding slot until the reset rod 243 contacts the top end of the second arm 22, thereby fixing the angle between the second arm 22 and the plane of the seat plate. When it is necessary to release the angle fixing component, the reset rod 243 is pulled to move toward the top end of the sliding slot, and the reset rod 243 is no longer in contact with the second arm 22, thereby achieving unlocking.

[0048] In some optional embodiments, the second arm 22 is a bent structure, and when the second arm 22 is placed vertically, the first limiting column 241 contacts the inner side of the bending angle of the second arm 22 .

[0049] In some optional embodiments, the first arm 21 is a bent structure.

[0050] Please refer to Figure 2 , Figure 2 Schematic diagram of the release process of the folding seat 2 provided in the embodiment of the present application. When the folding seat 2 is in the unfolded state, the user only needs to pull the reset rod 243 to slide to the top of the sliding groove to unlock the angle fixing mechanism, and then rotate the seat plate counterclockwise in the figure to realize the conversion from the unfolded state to the folded state.

[0051] Please refer to Figure 3 , Figure 3 A schematic diagram of the unfolding process of the folding seat 2 provided in the embodiment of the present application. In the folding state, the user only needs to rotate the seat plate in the clockwise direction in the figure. During the process, the reset rod 243 moves from the bottom end of the sliding groove to the top end until the seat plate reaches the highest position. After the reset rod 243 reaches the top end of the sliding groove, it is no longer pushed by the oblique guide surface of the second arm 22. The reset rod 243 returns to the bottom end of the sliding groove under the pulling force of the spring 244, and combines with the first limiting column 241 and the second limiting column 242 to fix the second arm 22. At this time, the folding seat 2 is fully unfolded.
