[0001] This utility model relates to the field of personal mobility vehicles, and in particular to a folding personal mobility vehicle. Background Technology

[0002] In modern society, with the increasing aging of the population, the travel needs of the elderly are receiving growing attention. Personal mobility aids, as a common assistive mode of transportation, greatly facilitate the daily travel of the elderly. They help seniors with limited mobility to participate more freely in social activities, shopping, and leisure activities, effectively improving their quality of life.

[0003] However, existing mobility scooters have revealed some significant problems in practical use, especially in terms of storage. Current mobility scooters are generally large, and their overall structure cannot be effectively altered for storage. For example, many traditional mobility scooters use a one-piece design with fixed wheel spacing, making it difficult to fold or disassemble the seat and frame. This often results in requiring a large amount of space for storage, such as in garages or corners of living rooms, causing considerable inconvenience to users. This problem is particularly prominent in urban apartments with limited living space, where many elderly people are deterred from purchasing mobility scooters due to lack of storage space. Furthermore, the large size makes carrying and loading the scooter extremely difficult when needed, such as for travel on public transportation or storage in a car trunk, severely limiting its usability and portability.

[0004] Given the shortcomings of existing mobility scooters in terms of storage, there is an urgent need in the market to develop a new type of mobility scooter that can effectively reduce storage volume, in order to meet the needs of the elderly for convenient storage and use of mobility scooters in different life scenarios, and further promote the development and improvement of assistive travel tools for the elderly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a foldable mobility scooter, which can effectively reduce its storage volume by folding.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is a foldable mobility scooter, including a steering rod, a front wheel assembly, a rear wheel assembly, a frame assembly, and a seat assembly. The frame assembly is installed between the front wheel assembly and the rear wheel assembly, and the seat assembly is installed on the frame assembly. The frame assembly adopts a foldable connection. The frame assembly includes a front frame and a rear frame. The front end of the rear frame is axled to the middle area of ​​the rear frame, and the rear end of the front frame is axled to the seat support of the seat assembly. A folding linkage mechanism is provided between the two support rods of the rear frame. The mechanism is connected to a telescopic drive rod. The extension of the telescopic drive rod controls the counterclockwise rotation of the folding linkage mechanism, and the retraction of the telescopic drive rod controls the clockwise rotation of the folding linkage mechanism. The folding linkage mechanism is connected to the middle area of ​​the front body frame through a first connecting rod. When the drive rod is retracted, the folding linkage mechanism rotates clockwise, and the first connecting rod pulls the middle area of ​​the front body frame, causing the front body frame and the rear body frame to fold together. When the drive rod is extended, the folding linkage mechanism rotates counterclockwise, and the first connecting rod pushes open the middle area of ​​the front body frame, causing the front body frame and the rear body frame to unfold away from each other.

[0007] A further preferred embodiment of this utility model is as follows: the folding linkage mechanism includes a connecting seat, a rotating rod, and two rotating arms. One end of the connecting seat is connected to the middle of the rotating rod, and the other end is connected to a telescopic drive rod. The two rotating arms are respectively disposed at both ends of the rotating rod. The movement of the connecting seat drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating arms to rotate.

[0008] A further preferred embodiment of this utility model is as follows: the rotating arm is L-shaped, one end of the rotating arm is fixed with a rotating rod, the other end of the rotating arm is axially connected to the first connecting rod, the middle part of the rotating arm is axially connected to the front end of the rear vehicle frame, and the rotation of the rotating arm drives the first connecting rod to move back and forth.

[0009] A further preferred embodiment of this utility model is as follows: a first transmission rod is provided between the two support rods of the front body frame, the first transmission rod is axially connected to the first connecting rod, and the first connecting rod pulls or pushes the front body frame through the first transmission rod.

[0010] A further preferred embodiment of this utility model is as follows: the two ends of the folding linkage mechanism are further provided with second connecting rods, the other end of the second connecting rods being connected to the front end of the front body frame. When the drive rod is retracted, the folding linkage mechanism rotates clockwise, and the second connecting rod pulls the front end area of ​​the front body frame, causing the front body frame and the rear body frame to fold together. When the drive rod is extended, the folding linkage mechanism rotates clockwise, and the second connecting rod pushes open the front end area of ​​the front body frame, causing the front body frame and the rear body frame to unfold away from each other.

[0011] A further preferred embodiment of this utility model is: the seat cushion bracket of the seat cushion assembly consists of two foldable brackets in an X-shape, with the front end of the front frame shaft connected to one end of the brackets, and the seat cushion brackets folding when the front frame and the rear frame are folded.

[0012] A further preferred embodiment of this utility model is as follows: a second transmission rod is provided between the two support rods of the rear body frame, and a third connecting rod is axled on the second transmission rod, with the other end of the third connecting rod axled to the front end of the front body frame.

[0013] A further preferred embodiment of this utility model is: the front end of the front body frame is a front mounting frame, and the steering rod is mounted on the front mounting frame.

[0014] A further preferred embodiment of this utility model is that the first connecting rod is curved.

[0015] When a user of this invention needs a foldable personal transportation tool, they only need to operate the telescopic drive rod to shorten it. As the telescopic drive rod shortens, the folding linkage mechanism is driven to rotate clockwise. The folding linkage mechanism is connected to the first connecting rod, and during rotation, the first connecting rod powerfully pulls the middle area of ​​the front frame. Since the front end of the rear frame is axled to the middle area of ​​the front frame, under this pulling force, the axle joint of the front and rear frames becomes the pivot point, and the two frames begin to rotate, gradually moving closer to each other, ultimately folding the front and rear frames together. This folding process is smooth and natural, with all components working in tandem, stably and efficiently reducing the size of the personal transportation tool quickly, making storage effortless. When the user needs to unfold the personal transportation tool for use, they simply extend the telescopic drive rod. The extension of the telescopic drive rod causes the folding linkage mechanism to rotate counterclockwise, at which point the first connecting rod moves accordingly, pushing open the middle area of ​​the front frame, causing the front and rear frames to unfold away from each other around the axle joint, quickly returning to their normal use state. The foldable design of the frame components, with its precise control of the folding linkage via a telescopic drive rod, greatly enhances user convenience. Whether for daily storage or carrying it on outings, users can easily and quickly adjust the size of their mobility scooter to suit their needs. When stored, it significantly reduces space requirements, solving the problem of large storage space in traditional mobility scooters; when carried out, its compact size makes it more convenient, expanding the usage scenarios of the mobility scooter and effectively improving its practicality and flexibility.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-6As shown, a folding mobility scooter includes a steering rod 1, a front wheel assembly 2, a rear wheel assembly 3, a frame assembly 4, and a seat assembly 5. The frame assembly 4 is installed between the front wheel assembly 2 and the rear wheel assembly 3, and the seat assembly 5 is installed on the frame assembly 4. The frame assembly 4 is characterized by having a folding mechanism. The frame assembly 4 includes a front frame 6 and a rear frame 7. The front end of the rear frame 7 is axled to the middle region of the rear frame 7, and the rear end of the front frame 6 is axled to the seat support 8 of the seat assembly 5. A folding linkage mechanism 9 is provided between the two support rods of the rear frame 7, and the folding linkage mechanism 9 is connected to a telescopic drive rod 1. The extension of the telescopic drive rod 10 controls the counterclockwise rotation of the folding linkage mechanism 9, and the retraction of the telescopic drive rod 10 controls the clockwise rotation of the folding linkage mechanism 9. The folding linkage mechanism 9 is connected to the middle area of ​​the front frame 6 via the first connecting rod 11. When the drive rod 10 is retracted, the folding linkage mechanism 9 rotates clockwise, and the first connecting rod 11 pulls the middle area of ​​the front frame 6, causing the front frame 6 and the rear frame 7 to fold together. When the drive rod 10 is extended, the folding linkage mechanism 9 rotates counterclockwise, and the first connecting rod 11 pushes open the middle area of ​​the front frame 6, causing the front frame 6 and the rear frame 7 to unfold away from each other. When the user of this utility model needs to fold the personal transportation tool, they operate the telescopic drive rod 10 to retract it, at which time the folding linkage mechanism 9 is driven to rotate clockwise. The folding linkage mechanism 9 pulls the middle area of ​​the front frame 6 via the first connecting rod 11. The front end of the rear frame 7 is axled to the middle area of ​​the front frame 6. Under the pulling force, the axle joint of the front frame 6 and the rear frame 7 rotates, thereby realizing the folding and closing of the front frame 6 and the rear frame 7. The whole process is smooth and stable, quickly reducing the size of the mobility scooter and making it easy to store. When the user needs to unfold the mobility scooter, the telescopic drive rod 10 extends, the folding linkage mechanism 9 rotates counterclockwise, the first connecting rod 11 pushes open the middle area of ​​the front frame 6, and the front frame 6 and the rear frame 7 unfold away from each other, returning to the normal use state. This foldable mechanism design of the frame assembly 4, through the precise control of the folding linkage mechanism 9 by the telescopic drive rod 10, greatly facilitates users to quickly change the size of the mobility scooter according to actual needs. It can significantly reduce the space occupied when stored and is more convenient to carry when going out, improving the practicality and flexibility of the mobility scooter.

[0024] The folding linkage mechanism 9 includes a connecting seat 12, a rotating rod 13, and two rotating arms 14. One end of the connecting seat 12 is connected to the middle of the rotating rod 13, and the other end is connected to the telescopic drive rod 10. The two rotating arms 14 are respectively located at both ends of the rotating rod 13. The movement of the connecting seat 12 drives the rotating rod 13 to rotate, and the rotation of the rotating rod 13 drives the rotating arms 14 to rotate. The folding linkage mechanism 9 adopts a structural design of connecting seat 12, rotating rod 13, and two rotating arms 14. The movement of the connecting seat 12 drives the rotating rod 13 to rotate, which in turn drives the rotating arms 14 to rotate. This simple and efficient transmission structure can accurately and stably transmit power when operating the telescopic drive rod 10. It can ensure smooth folding and unfolding operations, whether in frequent folding operations or after long-term use. The rotating arm 14 is L-shaped. One end of the rotating arm 14 is fixed to the rotating rod 13, and the other end of the rotating arm 14 is axled to the first connecting rod 11. The middle of the rotating arm 14 is axled to the front end of the rear frame 7. The rotation of the rotating arm 14 drives the first connecting rod 11 to move back and forth. The rotating arm 14 is L-shaped, with one end fixed to the rotating rod 13, the other end axled to the first connecting rod 11, and the middle section axled to the front end of the rear chassis frame 7. When rotating, the L-shaped rotating arm 14 uses a unique mechanical structure to drive the first connecting rod 11 to move back and forth. A first transmission rod 15 is provided between the two support rods of the front chassis frame 6, and the first transmission rod 15 is axled to the first connecting rod 11. The first connecting rod 11 pulls or pushes the front chassis frame 6 through the first transmission rod 15. This pulling or pushing of the front chassis frame 6 by the first connecting rod 11 through the first transmission rod 15 enhances the structural strength and motion synchronization of the front chassis frame 6 during folding and unfolding.

[0025] The folding linkage mechanism 9 is further equipped with second connecting rods 16 at both ends. The other end of the second connecting rod 16 is connected to the front end of the front frame 6. When the drive rod 10 is retracted, the folding linkage mechanism 9 rotates clockwise, and the second connecting rod 16 pulls the front end area of ​​the front frame 6, causing the front frame 6 and the rear frame 7 to fold together. When the drive rod 10 is extended, the folding linkage mechanism 9 rotates clockwise, and the second connecting rod 16 pushes open the front end area of ​​the front frame 6, causing the front frame 6 and the rear frame 7 to unfold away from each other. When the drive rod 10 is extended, the second connecting rod 16 and the first connecting rod 11 apply force simultaneously from the front end and middle of the front frame 6. During folding, the front frame 6 can be closed more quickly and smoothly to the rear, reducing folding time; during unfolding, the position of the front frame 6 can be precisely controlled to ensure that the unfolded body structure is accurately reset, further improving the folding effect and the stability of the overall structure, making the operation of the mobility scooter more convenient and efficient.

[0026] The seat cushion assembly 5 has two foldable X-shaped support brackets 8. The front end of the front frame 6 is connected to one end of the support bracket 8. When the front frame 6 and the rear frame 7 are folded, the seat cushion support 8 is also folded. When the frame assembly 4 is folded, the seat cushion support 8 folds simultaneously. When folded for storage, the overall storage volume is further reduced, allowing the scooter to be placed more compactly.

[0027] A second transmission rod 17 is installed between the two support rods of the rear frame 7. A third connecting rod 18 is axled on the second transmission rod 17, and the other end of the third connecting rod 18 is axled to the front end of the front frame 6. This structure increases the connection strength and force transmission efficiency between the front and rear frames. During folding and unfolding, it better maintains the integrity of the overall structure; even after multiple operations, the overall structure of the mobility scooter is not easily loosened.

[0028] The front end of the front frame 6 is a front mounting bracket 19, on which the steering rod 1 is mounted. This layout ensures that the steering rod 1 is securely mounted, guaranteeing precise and responsive steering when driving the vehicle. Whether turning in residential areas or navigating through shopping malls, it is easy to control, improving the safety and comfort of travel.

[0029] The first connecting rod 11 is curved. This curved design, without affecting the transmission function, better adapts to the spatial layout of the frame assembly 4 and avoids interference with other components. During folding and unfolding, the curved first connecting rod 11 can also buffer stress to a certain extent, reducing wear caused by rigid collisions, extending the service life of the first connecting rod 11, and reducing maintenance costs.

[0030] The folding mobility scooter provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
