[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a mobility scooter for use by people with mobility impairments. (Refer to...) Figure 1 The mobility scooter for people with mobility impairments includes a rear frame 1 and a front frame 2 slidably connected to the rear frame 1. The front frame 2 is equipped with a folding upright tube 21 for controlling wheel rotation, and the rear frame 1 is equipped with a seat 11. The user sits on the rear frame 1 and rests their hands on the folding upright tube 21 to control the scooter's forward movement and steering. The front frame 2 is also equipped with a cable assembly 3, which is used to adjust the distance between the front frame 2 and the rear frame 1.

[0031] Reference Figure 1 and Figure 2 The rear frame 1 includes a rear frame assembly 12, which includes a pair of symmetrically arranged connecting frames 121. Each connecting frame 121 is elongated and has a C-shaped cross-section. The pair of connecting frames 121 are located at the two ends of the rear frame assembly 12. The front frame 2 includes a bottom front panel assembly 22, which includes a base plate 221 and square frames 222 disposed on both sides of the base plate 221. The square frames 222 are steel square tubes, and their sidewalls are welded to the edges of the base plate 221. The square frames 222 are disposed within the corresponding connecting frames 121 and slide within the connecting frames 121.

[0032] Reference Figure 3 and Figure 4To improve the sliding effect, each connecting frame 121 has multiple rollers 122 at its bottom. These rollers 122 are evenly distributed along the length of the connecting frame 121, each roller 122 is vertically positioned, and the center of rotation of each roller 122 is vertical. Each square frame 222 has a slide rail 223 at its bottom, with an opening at the bottom. The top of the slide rail 223 is welded to the bottom of the square frame 222. Supporting protrusions 224 extend along the length of the slide rail 223 on both side walls. The center of each roller 122 is concave inwards in an arc shape, and the center of each roller 122 abuts against the supporting protrusion 224. The front plate assembly 22 abuts against the rollers 122 via the supporting protrusions 224, moving forward or backward by the rolling of the rollers 122.

[0033] Reference Figure 1 and Figure 3 The cable assembly 3 includes a cable switch 31 fixed to the folding riser 21 and a traction cable 32 arranged on the front frame 2. A positioning pin 33 is connected to the bottom end of the traction cable 32. The positioning pin 33 is used to sequentially pass through the square frame 222 and the connecting frame 121 to connect and fix the front frame 2 and the rear frame 1. Specifically, each square frame 222 has a through hole 225, and a C-shaped retaining spring is located near the through hole 225 on the square frame 222. The positioning pin is fixed in the square frame 222 by the C-shaped retaining spring, ensuring that the positioning pin 33 remains in working condition even if the cable comes loose, increasing the safety factor. Each connecting frame 121 has multiple positioning holes 123. The multiple positioning holes 123 and the through hole 225 are at the same height, and the multiple positioning holes 123 are evenly distributed along the length of the connecting frame 121. A return spring 38 is also fitted onto the positioning pin 33, and the return spring 38 is located in the square frame 222. When moving the front frame 2 and rear frame 1, the pull cable switch 31 is activated, causing the traction cable 32 to move and pull the bottom positioning pin 33 to move as well. The positioning pin 33 retracts into the square frame 222, compressing the return spring 38. The top of the positioning pin 33 disengages from the connecting frame 121, and the front frame 2 slides relative to the rear frame 1. When the frame is in the appropriate position, the pull cable switch 31 is activated again, releasing the elastic potential energy of the return spring 38. The return spring 38 then causes the bottom positioning pin 33 to extend out of the square frame 222, with its front end inserting into the positioning hole 123 in the connecting frame 121, thus fixing the relative positions of the front frame 2 and the rear frame 1. The pull cable switch 31 is located at the folding upright tube 21, allowing the operator to easily operate the frame without bending over, providing great convenience for people with mobility impairments.

[0034] Reference Figure 1The pull-cord switch 31 includes a mounting base 34 fixed to the folding riser 21 and a rotary wrench 35 rotatably mounted on the mounting base 34. The mounting base 34 is fixed to the folding riser 21 by bolts, but welding, riveting, snap-fitting, or gluing are also possible methods to securely fix the mounting base 34 to the folding riser 21. A rotating shaft extends outward from the mounting base 34, and the rotary wrench 35 is rotatably connected to the mounting base 34 via the rotating shaft. The rotation center line of the rotary wrench 35 is horizontal, but it can also be vertical or inclined for ease of operation. The end of the pull cord 32 is snapped into the rotary wrench 35 and can rotate with the rotary wrench 35. Alternatively, the end of the pull cord 32 can be welded or tied to the rotary wrench 35.

[0035] Reference Figure 1 and Figure 2 The cable assembly 3 also includes a sleeve 36, through which the traction cable 32 passes. The sleeve 36 is made of plastic, but can also be made of rubber or metal. The top end of the sleeve 36 is fixed to the bottom end of the fixing seat 34 by snap-fit ​​or adhesive. The bottom end of the sleeve 36 is fixed to the bottom end of the front vehicle panel assembly 22. Specifically, a fastening seat 37 is welded to the side wall of the square frame 222, and the bottom end of the sleeve 36 passes through the fastening seat 37, allowing the traction cable 32 to move back and forth within the sleeve 36. Specifically, the bottom end of the sleeve 36 has threads, and a pair of nuts are fitted onto the bottom end of the sleeve 36. The pair of nuts are located at both ends of the fastening seat 37. By finely adjusting the position of the bottom end of the sleeve 36 and tightening the pair of nuts onto the fastening seat 37, the bottom end of the sleeve 36 is fixed in place. A guide post 226 is provided at the bottom end of the base plate 221. The guide post 226 is welded to the base plate 221. The traction line 32 led out from the sleeve 36 passes around the guide post 226 and bends at 90°. The direction changes from parallel to the square frame 222 to perpendicular to the square frame 222, so that the positioning pin 33 at the end of the traction line 32 is inserted vertically into the square frame 222.

[0036] Reference Figure 3 To improve the positioning effect, the bottom end of the traction line 32 is divided into two, and pins are set in a pair of square frames 222 to facilitate positioning and fixation.

[0037] The implementation principle of this embodiment is as follows: The operator sits on the seat 11 of the rear frame 1 and rotates the rotary handle located on the folding upright tube 21. The positioning pin 33 at the bottom retracts into the square frame 222, and the end of the positioning pin 33 disengages from the corresponding connecting frame 121. At this time, the operator uses their foot to brace against the front frame 2 and applies a forward or backward force to the front frame 2, causing the front frame assembly 22 and the rear frame assembly 12 to shift. After moving to the appropriate position, the operator rotates the rotary wrench 35 again, causing the positioning pin 33 to re-enter the positioning hole 123 in the connecting frame 121, thereby fixing the front frame 2 and completing the adjustment work.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered by the scope of protection of this application.
