[0053] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0054] As shown in Figures 1 to 27, the present application provides a walker, comprising a frame 100, a footrest assembly 300, a backrest assembly 400, and a seat cushion assembly 200. The seat cushion assembly 200 is mounted on the frame 100 for the user to sit on and can be switched from an assisted walking state to a wheelchair state according to the user's needs. That is, the walker can switch from a wheelchair state to a convenient place for the disabled to rest and relieve fatigue during the movement, or it can propel the disabled sitting on the seat cushion assembly 200, allowing the disabled to travel a longer distance. The backrest assembly 400 is rotatably connected or detachably mounted on the frame 100 and is located above the seat cushion assembly 200, for the user to rest on to relieve fatigue. The footrest assembly 300 is rotatably connected or detachably mounted on the frame 100 for the user to step on, thereby improving the riding comfort of the walker. At the same time, it can be rotated and retracted or removed relative to the frame 100 when the footrest is not needed, saving space, effectively reducing the collision of the walker with obstacles when moving, and facilitating the movement of the walker.

[0055] In some embodiments, the frame 100 includes a frame body 20, which includes a first frame 21, a second frame 22, and a connecting frame 23. The first frame 21 is connected to the second frame 22 via the connecting frame 23 and can be folded toward the second frame 22, thereby folding when not in use, facilitating packaging, transportation, and storage. The seat cushion assembly 200 is mounted on the connecting frame 23, and the backrest assembly and footrest assembly 300 are both rotatably connected or detachably mounted to the first frame 21 and the second frame 22. This simple structure allows for easy interchange between an unfolded state and a folded state, making it convenient for personal portability.

[0056] In an optional embodiment, the connecting frame 23 includes a first cross rod 231 and a second cross rod 232 that are cross-arranged and can rotate relative to each other in the cross position, wherein one end of the first cross rod 231 and the second cross rod 232 are connected to the first frame 21, and the other end of the first cross rod 231 and the second cross rod 232 are connected to the second frame 22, and the two ends of the seat cushion assembly 200 are respectively connected to the first cross rod 231 and the second cross rod 232, so that the first frame 21 and the second frame 22 can be unfolded or folded through the connecting frame 23.

The first and second connecting portions 23 and 25 are provided on both the first and second frames 21 and 22. A cross-rod hinge point is provided at the middle of the first and second cross-rods 231 and 232, and the first and second cross-rods 231 and 232 can be unfolded or folded about the cross-rod hinge point. One end of the first and second cross-rods 231 and 232 is rotatably connected to the second connecting portion 25, and the other end of the first cross-rod 231, or a position closer to the other end from the cross-rod hinge point, is rotatably connected to the first connecting portion 23 via the first connecting block 233. The other end of the second cross-rod 232, or a position closer to the other end from the cross-rod hinge point, is rotatably connected to the first connecting portion 23 via the second connecting block 234.

[0058] In this embodiment, the frame 100 includes a handrail 10, which is rotatably connected to the first frame 21 and the second frame 22, allowing the user to utilize the walker with the handrail 10 for assistive functions such as standing and walking. Furthermore, the handrail 10 can be rotated and positioned relative to the first frame 21 and the second frame 22 to achieve ergonomic operation and ensure safety.

[0059] In an optional embodiment, the handrail tube 10 includes a first handrail tube 11 and a second handrail tube 12. The first handrail tube 11 is rotatably connected to the first frame 21, and the second handrail tube 12 is rotatably connected to the second frame 22. The first handrail tube 11 and the second handrail tube 12 have a first tilted state forming a first angle with the support surface on which the frame 100 is placed, and a second tilted state forming a second angle with the support surface. The first angle is within the range of 80°-90°, and the second angle is within the range of 65°-75°.

[0060] After adopting the above technical solution, the first handrail tube 11 and the second handrail tube 12 can be conveniently switched and maintained between the first tilted state and the second tilted state, so that the first handrail tube 11 and the second handrail tube 12 can be rotated and adjusted in angle and positioned to achieve ergonomic operation and convenience, making the walker more humane, and can be switched between the first tilted state and the second tilted state according to the user's usage, thereby improving the comfort of using the walker, enriching the function of the walker, and also alleviating the fatigue after using the walker.

[0061] In an optional embodiment, the first frame 21 includes a first support rod 211 provided with a first roller member 215, the second frame 22 includes a second support rod 221 provided with a second roller member 225, the first handrail tube 11 is rotatably connected to the middle of the first support rod 211, and the second handrail tube 12 is rotatably connected to the middle of the second support rod 221, so that the user can walk more easily with the help of the walker, while also ensuring the balance of the frame 100.

[0062] Exemplarily, the number of the first roller members 215 and the second roller members 225 is two, the two first roller members 215 are correspondingly arranged at the two ends of the first support rod 211, the first handrail tube 11 is arranged between the two first roller members 215, the two second roller members 225 are correspondingly arranged at the two ends of the second support rod 221, and the second handrail tube 12 is arranged between the two second roller members 225.

[0063] In an optional embodiment, a first adjusting member is provided on the first frame 21, and the first adjusting member is connected to the first armrest tube 11 and the first frame 21, and is used to switch the first armrest tube 11 between the first tilt state and the second tilt state when operated. The specific setting can be made according to the needs of the user.

[0064] In an optional embodiment, a second adjusting member is provided on the second frame 22, and the second adjusting member is connected to the second armrest tube 12 and the second frame 22, and is used to switch the second armrest tube 12 between the first tilt state and the second tilt state when operated. The specific setting can be made according to the needs of the user.

[0065] It should be noted that the first handrail tube 11 and the second handrail tube 12 have the same inclination state relative to the first frame 21 and the second frame 22, so that the use of the walker can be facilitated, that is, when the first handrail tube 11 is in the first inclination state, the second frame 22 also needs to be adjusted to the first inclination state through the second adjusting member. Similarly, when the first handrail tube 11 is in the second inclination state, the second frame 22 also needs to be adjusted to the second inclination state through the second adjusting member.

[0066] In an optional embodiment, the first frame 21 includes a first distance rod 212, and the first distance rod 212 and the first support rod 211 are spaced apart along the height direction of the first frame 21, wherein the first handrail tube 11 is movably connected to the first distance rod 212 through a first adjusting member, so that the first handrail tube 11 can adjust the angle between itself and the first distance rod 212 through the first adjusting member, thereby realizing the angle adjustment between the first handrail tube 11 and the first support rod 211, that is, the first handrail tube 11 switches between the first tilt state and the second tilt state, which can be adjusted specifically according to the needs of the user.

[0067] In an optional embodiment, the second frame 22 includes a second distance rod 222, and the second distance rod 222 and the second support rod 221 are spaced apart in the height direction of the first frame 22, wherein the second handrail tube 12 is movably connected to the second distance rod 222 through a second adjusting member, so that the second handrail tube 12 can adjust the angle between itself and the second distance rod 222 through the second adjusting member, thereby realizing the angle adjustment between the second handrail tube 12 and the first support rod 211, that is, the second handrail tube 11 switches between the first tilt state and the second tilt state, which can be adjusted specifically according to the needs of the user.

[0068] It should be noted that the tilt states of the second armrest tube 12 and the first armrest tube 11 after adjustment can be the same, or different, depending on the user's needs. Furthermore, since the two are adjusted separately, there is a certain amount of error during the adjustment process. Therefore, this application does not limit the tilt states of the second armrest tube 12 and the first armrest tube 11 after adjustment.

[0069] In an optional embodiment, the first adjustment member and the second adjustment member have a first adjustment position and a second adjustment position. When the first handrail tube 11 and the second handrail tube 12 are fixed at the first adjustment position, the first handrail tube 11 and the second handrail tube 12 are in a first tilted state; when the first handrail tube 11 and the second handrail tube 12 are fixed at the second adjustment position, the first handrail tube 11 and the second handrail tube 12 are in a second tilted state. The first adjustment position and the second adjustment position can be two separate fixed portions on the first adjustment member and the second adjustment member, or the first adjustment position and the second adjustment position can be any two positions of the slide rails on the first adjustment member and the second adjustment member, or even the first adjustment position and the second adjustment position can be two telescopic positions of a telescopic structure, and this application is not limited thereto.

[0071] It should be noted that the limiting member includes but is not limited to an adjusting screw, which passes through the adjusting rail 132 and is connected to the first handrail tube 11 and the second handrail tube 12. When it is necessary to adjust the rotation angle of the first handrail tube 11 and the second handrail tube 12, the adjusting screw is loosened so that the first handrail tube 11 and the second handrail tube 12 can move toward or away from the first distance rod 212 and the second distance rod 222. When the first handrail tube 11 and the second handrail tube 12 are adjusted to the first adjustment position or the second adjustment position, the adjusting screw is tightened so that the first handrail tube 11 and the second handrail tube 12 can be fixed at the first adjustment position or the second adjustment position, thereby achieving adjustment of the inclination state of the first handrail tube 11 and the second handrail tube 12.
