[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A mobility structure for a mobility scooter and an intelligent mobility scooter. The intelligent mobility scooter uses the scooter body 1 as the basic carrier and realizes multi-mode mobility functions through the limiting support seat 2, seat steering mechanism 3, walking assistance mechanism 4 and related drive components installed on the surface.

[0025] The mobility scooter body 1 serves as the overall support base, and a limiting support seat 2 is fixedly installed on its surface. The limiting support seat 2 provides an installation reference for the walking assistance mechanism 4. The surface of the mobility scooter body 1 is also fixedly provided with a seat steering mechanism 301, which ensures the stable installation of the seat 302 and the steering components.

[0026] It is worth noting that the core component of the walking assistance mechanism 4 is installed on the limiting support seat 2: the limiting support seat 2 has a limiting installation groove 401 on its surface, and the limiting support shaft 402 is rotatably installed on the inner wall of the limiting installation groove 401. The rotational cooperation between the two provides a basis for the angle adjustment of the walking assistance mechanism 4.

[0027] The surface of the limiting support shaft 402 is fixedly connected to the cylindrical support shell 403. The inner wall of the cylindrical support shell 403 is slidably connected to the adjusting block 404. The adjusting block 404 can move up and down along the inner wall of the cylindrical support shell 403 to achieve height adjustment. The top of the adjusting block 404 is fixedly connected to the operation panel 405. The operation panel 405 serves as a functional integration platform, and its front end is fixedly connected to the L-shaped mounting base 406.

[0028] The L-shaped mounting base 406 has corresponding limiting shaft holes 407 on both sides. The movable positioning rod 408 is rotatably mounted on the inner wall of the limiting shaft hole 407. The movable positioning rod 408 can rotate flexibly around the limiting shaft hole 407 to facilitate adjustment of the angle of the push rod handle 410. The left and right ends of the movable positioning rod 408 extend to the outside of the L-shaped mounting base 406 and are fixedly connected to the extension rod 409. The end of the extension rod 409 away from the movable positioning rod 408 is fixedly connected to the push rod handle 410. The push rod handle 410 provides a gripping point for the companion to push or for the user to support.

[0029] The L-shaped mounting base 406 has a positioning screw hole on its front side. The positioning bolt 411 is threaded into the positioning screw hole. The movable positioning rod 408 has a positioning slot 412 on its surface. The positioning slot 412 corresponds to the positioning bolt 411 in position and matches its size. When the positioning bolt 411 is screwed into the positioning slot 412, the angle of the movable positioning rod 408 can be fixed to prevent the stability from being affected by shaking during use.

[0030] Two handlebars 413 are fixedly installed at the rear of the control panel 405. The handlebars 413 are U-shaped, which fits the hand grip habit and makes it easy for the user to control the direction of travel and start and stop of the vehicle.

[0031] The limiting support base 2 has an adjustment groove inside. The adjustment motor 5 is fixedly installed on the inner wall of the adjustment groove. The rotating shaft of the adjustment motor 5 is fixedly connected to the worm gear 6. One end of the limiting support shaft 402 extends into the adjustment groove and is fixedly connected to the worm wheel 7. The worm gear 6 meshes with the worm wheel 7. When the adjustment motor 5 is started, the meshing transmission between the worm gear 6 and the worm wheel 7 drives the limiting support shaft 402 to rotate, thereby adjusting the angle of the cylindrical support shell 403 and the operation panel 405, realizing the precise adjustment of the overall angle of the walking assistance mechanism 4 to adapt to different usage scenarios.

[0032] A lifting motor 8 is fixedly installed on the inner bottom wall of the cylindrical support shell 403. The rotating shaft of the lifting motor 8 is fixedly connected to the threaded rod 9. The bottom end of the adjusting block 404 has a threaded groove that matches the threaded rod 9. The adjusting block 404 is threadedly connected to the threaded rod 9 through the threaded groove. When the lifting motor 8 drives the threaded rod 9 to rotate, the adjusting block 404 moves up and down along the inner wall of the cylindrical support shell 403, thereby adjusting the height of the operation panel 405 and the handle assembly to accommodate users of different heights.

[0033] It is worth noting that the fixed seat 301 of the seat steering mechanism 3 is fixedly installed on the surface of the vehicle body 1. The upper surface of the fixed seat 301 is rotatably connected to the seat 302, and the seat 302 can rotate relative to the fixed seat 301. A rectangular cavity is opened inside the fixed seat 301. The rotating support column 303 is rotatably connected to the inner bottom wall of the rectangular cavity. The top end of the rotating support column 303 extends to the outside of the rectangular cavity and is fixedly connected to the lower surface of the seat 302. The rotating support column 303 provides support for the rotation of the seat 302, ensuring that the seat 302 is stable and does not wobble when it rotates.

[0034] The surface of the rotating support column 303 is fixedly connected to the limiting block 304. The surface of the limiting block 304 is symmetrically provided with two limiting slots 305. The side of the fixed base 301 is provided with a groove. The inner wall of the groove is provided with a limiting through hole. The positioning column 306 is slidably installed on the inner wall of the limiting through hole. The end of the positioning column 306 is fixedly connected to the positioning insert 307. The positioning insert 307 matches the size of the limiting slot 305 and can be inserted into the limiting slot 305 to fix the angle of the rotating support column 303.

[0035] One end of the positioning post 306 is fixedly connected to the conversion handle 308. The upper and lower surfaces of the conversion handle 308 are fixedly connected to the reset block 309. A tension spring 310 is fixedly installed between the reset block 309 and the inner wall of the groove. The tension spring 310 applies a pulling force to the conversion handle 308 through the reset block 309, ensuring that the positioning insert 307 is stably inserted into the limiting slot 305 in the non-operating state, and preventing the seat 302 from rotating accidentally.

[0036] Specific operation and advantages of each mode: 1. Operation of the mobility scooter mode: Pull the conversion handle 308, the positioning block 307 disengages from the limit slot 305, rotate the seat 302 to the forward position (consistent with the driving direction), release the conversion handle 308, the tension spring 310 pulls the positioning block 307 to insert into the corresponding limit slot 305 to position the seat 302; start the lifting motor 8, which drives the adjusting block 404 to rise through the threaded rod 9, and adjust the operation panel 405 to a suitable height for sitting; rotate the movable positioning rod 408 to a position where the push rod handle 410 does not interfere with driving, and screw in the positioning bolt 411 to fix it.

[0037] Advantages: Users sit in seat 302 and control the vehicle via handlebars 413, making independent travel convenient and suitable for long-distance travel.

[0038] 2. Operation in wheelchair mode: Keep the seat 302 upright and fixed; rotate the movable positioning rod 408 to a horizontal position so that the push rod handle 410 is behind the seat 302, and screw in the positioning bolt 411 to fix the movable positioning rod 408; there is no need to adjust the height of the control panel 405 (or make minor adjustments according to the caregiver's habits).

[0039] Advantages: Caregivers can push the mobility scooter by holding the push lever handle 410. The push lever position is in line with the user's force exertion habits, making it easy to push and suitable for scenarios where users need assistance.

[0040] 3. Operation of the walking aid mode: Pull the conversion handle 308 to rotate the seat 302 to the side (to avoid obstructing the walking space), and release the conversion handle 308 to fix it; start the lifting motor 8 to lower the height of the operation panel 405 to a position suitable for standing support; rotate the movable positioning rod 408 to the angle of the push rod handle 410 for easy gripping, and fix the positioning bolt 411.

[0041] Advantages: When standing, the user can hold the handlebar 413 or the push bar handle 410 of the mobility scooter. The mobility scooter provides stable support, reduces the physical exertion of walking, and is suitable for short-distance walking or rehabilitation training.

[0042] Working Principle: This intelligent mobility scooter achieves multi-mode switching through the coordinated operation of its mechanical structures: In the walking assistance mechanism 4, the adjusting motor 5 drives the limiting support shaft 402 to rotate via the worm gear 6 and worm wheel 7, thereby adjusting the angle of the control panel 405; the lifting motor 8 drives the adjusting block 404 to rise and fall via the threaded rod 9, thereby adjusting the height of the control panel 405; the engagement of the movable positioning rod 408 and the positioning bolt 411 fixes the angle of the push rod handle 410 to meet different gripping needs. In the seat steering mechanism 3, the rotating support column 303 drives the seat 302 to rotate, and the engagement of the positioning insert 307 and the limiting slot 305 achieves stable positioning of the seat 302, avoiding rotational interference.

[0043] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
