Description

Technical Field

[0001] This utility model relates to the field of personal mobility vehicles, and more particularly to a single-pole driven 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 them occupying considerable space when stored at home, 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 single-pole driven folding mobility scooter, which can effectively reduce its storage volume through folding.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is a single-lever driven folding mobility scooter, including a steering lever, 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 is characterized by a foldable connection; the frame assembly includes a front frame and a rear frame.

[0007] 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 cushion bracket of the seat cushion assembly. A folding linkage mechanism is provided between the two support rods of the rear frame. The folding linkage mechanism is connected to the telescopic drive rod. The folding linkage mechanism includes a rotating rod, a first transmission component, a second transmission component, and two rotating arms. The first transmission component is fixed on the middle area of ​​the rotating rod. One end of the first transmission component is axled to the telescopic drive rod, and the other end is axled to the rear end of the connecting rod. The front end of the connecting rod is axled to the front end of the front frame. A first transverse connecting rod is provided between the two support rods of the front frame. The second transmission component is axled to the first transverse connecting rod through a first connecting component.

[0008] The extension of the telescopic drive rod causes the control folding linkage mechanism to rotate clockwise. The first transmission component applies a pulling force to the front end of the front frame through the linkage rod, and the second transmission component applies a pushing force to the first lateral link, so that the front frame and the rear frame fold together.

[0009] The shortening of the telescopic drive rod causes the control folding linkage mechanism to rotate counterclockwise. The first transmission component applies a thrust to the front end of the front frame through the linkage rod, and the second transmission component applies a pull to the first lateral link, causing the front frame and the rear frame to unfold away from each other.

[0010] A further preferred embodiment of this utility model is that the first transmission component is disposed below the rotating rod.

[0011] A further preferred embodiment of this utility model is: the linkage rod includes a connecting plate, and reinforcing side plates are provided on both sides of the connecting plate.

[0012] A further preferred embodiment of this utility model is: there are two first transmission components, which are respectively disposed on both sides of the telescopic drive rod and connected by a fixed shaft.

[0013] A further preferred embodiment of this utility model is that there are two second transmission components, which are disposed on both sides of the first transmission component.

[0014] A further preferred embodiment of this utility model is as follows: the seat cushion bracket of the seat cushion assembly includes four parallel rods, and the rear end of the front frame is connected to the parallel rods through a second connector. When the front frame rotates, it will push the parallel rods to rotate, thereby realizing the synchronous folding of the body and the seat cushion assembly.

[0015] A further preferred embodiment of this utility model is: the seat cushion bracket of the seat cushion assembly includes an X-shaped bracket, which folds when subjected to force, and the front frame rotates to push the X-shaped bracket to fold, thereby achieving synchronous folding of the vehicle body and the seat cushion assembly.

[0016] A further preferred embodiment of this utility model is: a second transverse connecting rod is provided between the two support rods of the rear vehicle frame, and the telescopic drive rod is fixed on the second transverse connecting rod.

[0017] Compared with the prior art, the frame assembly of this utility model adopts a foldable connection, which allows the elderly mobility scooter to be folded when not in use, greatly reducing the space occupied by the scooter and making it easy to store and carry. For example, it can be easily placed in the trunk of a vehicle or in a small indoor space. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-6As shown, a single-lever driven folding mobility scooter includes a steering lever 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 foldable. 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. The folding linkage mechanism 9 is connected to a telescopic drive rod 10, which can be a motor-controlled telescopic rod. The folding linkage mechanism 9 includes a rotating rod 11, a first transmission component 12, a second transmission component 13, and two rotating arms 14. The first transmission component 12 is fixed to the middle region of the rotating rod 11, and one end of the first transmission component 12 is axled. The telescopic drive rod 10 is connected to the rear end of the connecting rod 15, and the front end of the connecting rod 15 is connected to the front end of the front frame 6. A first transverse connecting rod 16 is provided between the two support rods of the front frame 6. The second transmission member 13 is connected to the first transverse connecting rod 16 through the first connecting member 17. When the telescopic drive rod 10 extends, it drives the control folding linkage mechanism 9 to rotate clockwise. The first transmission member 12 applies a pulling force to the front end of the front frame 6 through the connecting rod 15, and the second transmission member 13 applies a pushing force to the first transverse connecting rod 16, so that the front frame 6 and the rear frame 7 fold together. When the telescopic drive rod 10 shortens, it drives the control folding linkage mechanism 9 to rotate counterclockwise. The first transmission member 12 applies a pushing force to the front end of the front frame 6 through the connecting rod 15, and the second transmission member 13 applies a pulling force to the first transverse connecting rod 16, so that the front frame 6 and the rear frame 7 unfold away from each other.

[0026] The frame assembly 4 features a foldable connection, allowing the mobility scooter to be folded when not in use, significantly reducing its space occupation and making it easy to store and carry. For example, it can be easily placed in a vehicle trunk or a small indoor space. A telescopic drive rod 10 controls the folding linkage mechanism 9, enabling the front frame 6 and rear frame 7 to fold and unfold. This single-rod drive simplifies the operation; users only need to extend or retract the telescopic drive rod 10 to fold and unfold the scooter, reducing operational difficulty and making it especially suitable for the elderly. The first transmission component 12 and the second transmission component 13 in the folding linkage mechanism 9 apply tension or thrust to the front frame 6 via the connecting rod 15 and the first lateral connecting rod 16, respectively, making the folding and unfolding process more stable and smooth. The coordinated work of multiple transmission components distributes the stress points, preventing damage caused by excessive localized stress and extending the scooter's lifespan.

[0027] The first transmission component 12 is located below the rotating rod 11. This arrangement makes efficient use of the internal space of the frame assembly 4, avoids interference between transmission components, and makes the entire folding linkage mechanism 9 more compact, while also improving transmission efficiency.

[0028] The linkage 15 includes a connecting plate 22, with reinforcing side plates 23 on both sides of the connecting plate 22. The connecting rod 15, including the connecting plate and the reinforcing side plates, enhances the structural strength and stability of the linkage 15. During the transmission of tensile and thrust forces, the linkage 15 can withstand greater forces without easily deforming or being damaged, ensuring the reliability of the folding and unfolding actions.

[0029] There are two first transmission components 12, which are respectively disposed on both sides of the telescopic drive rod 10 and connected by a fixed shaft. The placement of two first transmission components 12 on both sides of the telescopic drive rod 10 and connected by a fixed shaft ensures that the force exerted by the telescopic drive rod 10 is evenly transmitted to the linkage rod 15, avoiding transmission deviations caused by uneven force on one side and improving the transmission stability and accuracy of the folding linkage mechanism 9.

[0030] There are two second transmission components 13, which are arranged on both sides of the first transmission component 12. The two second transmission components 13 are arranged on both sides of the first transmission component 12, which can apply tension or thrust to the first lateral connecting rod 16 more evenly, so that the front body frame 6 is subjected to more balanced forces during folding and unfolding, and further improves the stability and synchronization of the vehicle body movement.

[0031] A second transverse link 19 is provided between the two support rods of the rear frame 7, and the telescopic drive rod 10 is fixed to the second transverse link 19. The second transverse link 19 provides stable support and a fixing point for the telescopic drive rod 10. This ensures that the telescopic drive rod 10 remains stable during operation, accurately transmitting force to the folding linkage mechanism 9, and improving the reliability of the entire drive system.

[0032] Seat cushion components can be categorized into the following two types based on requirements:

[0033] H-type seat: The seat support 8 of the seat assembly 5 includes four parallel rods 20. The rear end of the front frame 6 is connected to the parallel rods via a second connector 18. When the front frame 6 rotates, it pushes the parallel rods to rotate, achieving synchronous folding of the frame and seat assembly 5. The seat support 8 of the seat assembly 5 uses four parallel rods; when the front frame 6 rotates, it pushes the parallel rods to rotate, achieving synchronous folding of the frame and seat assembly 5. This design makes the scooter more integrated during folding, reducing the tedious steps of folding the frame and seat separately, improving folding efficiency, and ensuring overall compactness after folding.

[0034] X-shaped seat cushion: The seat cushion support 8 of the seat cushion assembly 5 includes an X-shaped support 21. The X-shaped support folds under force, and the rotation of the front frame 6 pushes the X-shaped support to fold, achieving synchronous folding of the body and seat cushion assembly 5. The X-shaped support 8 of the seat cushion assembly 5 uses an X-shaped support, which folds when the front frame 6 rotates, also achieving synchronous folding of the body and seat cushion assembly 5. The X-shaped support has good foldability and load-bearing performance, enabling folding within a small space, further reducing the overall volume after folding, and has a simple structure and low cost.

[0035] The above provides a detailed description of the single-lever driven folding mobility scooter provided by this utility model. 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 various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
