[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0029] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having" and any variations thereof in the specification, claims and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0030] The terms "first," "second," etc., in the specification, claims, or the accompanying drawings of this application are used to distinguish different objects, rather than to describe a specific order or primary / secondary relationship.

[0031] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0032] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0033] With the development of the medical device industry, walking aids are gradually evolving towards convenient storage. However, some walking aids currently cannot be folded, resulting in a large storage space being occupied. While some walking aids can be folded, they typically use two cross-connecting rods to connect the two supports of the walking aid. One end of the connecting rod is fixed to the support along the direction of gravity, while the other end slides along the support. If the friction between the connecting rod and the support is high, or if the direction of force on the connecting rod and the support is inconsistent with the direction of sliding, the walking aid may easily get stuck during folding and unfolding, causing inconvenience. Furthermore, the sliding between the connecting rod and the support will cause wear and tear on the connecting rod and the support, affecting the lifespan of the walking aid.

[0034] To facilitate the folding and unfolding of the walking aid, this application provides a walking aid comprising a first support, a second support, a first connecting frame, multiple wheels, a first handrail, and a second handrail. The first support and the second support are spaced apart along a first direction. The first connecting frame includes a first connector and a second connector, which are rotatably connected. The end of the first connector away from the second connector is rotatably connected to the first support, and the end of the second connector away from the first connector is rotatably connected to the second support. The multiple wheels are respectively connected to the first support and the second support. The first handrail is connected to the first support, and the second handrail is connected to the second support. The first handrail and the second handrail are used for handholding.

[0035] In this type of walking aid, the first connector and the second connector are rotatably connected. The end of the first connector away from the second connector is rotatably connected to the first bracket, and the end of the second connector away from the first connector is rotatably connected to the second bracket. This allows the first and second connectors to rotate relative to each other, thereby bringing the first and second brackets closer together or separating, thus enabling the walking aid to open and close. The first and second connectors only need to rotate relative to each other during the opening and closing process, without slippage. This reduces the likelihood of jamming during opening and closing, making the walking aid more convenient to use. Furthermore, the first and second connectors, the first and second brackets, and the second bracket experience less wear, which helps extend the lifespan of the walking aid. Multiple wheels are connected to the first and second brackets respectively, making the movement of the walking aid more convenient. The first handlebar is connected to the first bracket, and the second handlebar is connected to the second bracket. The first and second handlebars are used for handholding, making the walking aid easy for the user to push.

[0036] See Figures 1 to 3 , Figure 1 A three-dimensional structural diagram of the walking aid provided in some embodiments of this application in the open state; Figure 2 A three-dimensional structural diagram of the walking aid provided in some embodiments of this application in a folded state; Figure 3This is a three-dimensional structural diagram of the walking aid provided in some embodiments of this application in the open state, from another perspective.

[0037] This application provides a walking aid 10, which includes a first support 100 and a second support 200, which are spaced apart along a first direction X. A first connecting frame 300 includes a first connector 310 and a second connector 320, which are rotatably connected. The end of the first connector 310 away from the second connector 320 is rotatably connected to the first support 100, and the end of the second connector 320 away from the first connector 310 is rotatably connected to the second support 200. A plurality of wheels 400 are respectively connected to the first support 100 and the second support 200. A first handrail 510 is connected to the first support 100, and a second handrail 520 is connected to the second support 200. The first handrail 510 and the second handrail 520 are used for hand holding.

[0038] By rotatably connecting the first connector 310 and the second connector 320, with the end of the first connector 310 away from the second connector 320 rotatably connected to the first bracket 100 and the end of the second connector 320 away from the first connector 310 rotatably connected to the second bracket 200, the first connector 310 and the second connector 320 can rotate relative to each other. This allows the first bracket 100 and the second bracket 200 to move closer to or separate from each other, thereby enabling the walking aid 10 to open and close. During the opening or closing of the walking aid 10, the first connector 310 and the second connector 320 only need to rotate relative to each other without slipping, thus achieving... This design reduces the likelihood of jamming during the opening or closing of the walker 10, making it more convenient to use. It also reduces wear on the first connector 310, the second connector 320, the first bracket 100, and the second bracket 200, thus extending the lifespan of the walker 10. Multiple wheels 400 are connected to the first bracket 100 and the second bracket 200 respectively, making the movement of the walker 10 easier. The first handle 510 is connected to the first bracket 100, and the second handle 520 is connected to the second bracket 200. Both handles are for handheld use, making the walker 10 easier for assistive users to push.

[0039] In some embodiments, the first connecting frame 300 includes a third connecting member 330 and a fourth connecting member 340, the third connecting member 330 is connected to the fourth connecting member 340, one end of the third connecting member 330 away from the fourth connecting member 340 is rotatably connected to the first bracket 100, and one end of the fourth connecting member 340 away from the third connecting member 330 is rotatably connected to the second bracket 200; the first connecting member 310 and the third connecting member 330 are arranged crosswise, and the second connecting member 320 and the fourth connecting member 340 are arranged crosswise.

[0040] By including a third connector 330 and a fourth connector 340 in the first connecting frame 300, with the third connector 330 connected to the fourth connector 340, the end of the third connector 330 away from the fourth connector 340 being rotatably connected to the first bracket 100, and the end of the fourth connector 340 away from the third connector 330 being rotatably connected to the second bracket 200, the third connector 330 and the fourth connector 340 can rotate relative to each other, thereby allowing the first bracket 100 and the second bracket 200 to move closer to or separate from each other, thus realizing the opening and closing of the walker 10. The third connector 330 and the fourth connector 340 only need to rotate relative to each other during the opening or closing of the walker 10, without slipping, which reduces the possibility of jamming during the opening or closing of the walker 10, making the walker 10 more convenient to use, and reducing the wear of the third connector 330, the fourth connector 340, the first bracket 100, and the second bracket 200, which helps to extend the service life of the walker 10. By arranging the first connector 310 and the third connector 330 in a cross configuration, and the second connector 320 and the fourth connector 340 in a cross configuration, the first connecting frame 300 can be made more stable during opening and closing, and the first connecting frame 300 is less prone to deformation, thus improving the stability of the walker 10.

[0041] In some embodiments, multiple first connecting frames 300 may be provided between the first support 100 and the second support 200, which can further make the first connecting frame 300 more stable during opening and closing, and the first connecting frame 300 is less prone to deformation, thus making the walker 10 more stable.

[0042] In some embodiments, the walker 10 includes a second connecting frame 600 connected between the first support 100 and the second support 200. The second connecting frame 600 is used to limit the first support 100 and the second support 200 in a first direction X after the walker 10 is opened.

[0043] By providing a second connecting frame 600 between the first support 100 and the second support 200, and by using the second connecting frame 600 to limit the first support 100 and the second support 200 in the first direction X after the walker 10 is opened, the second connecting frame 600 can provide limiting support for the first support 100 and the second support 200 after the walker 10 is opened, making it less likely for the first support 100 and the second support 200 to get close to each other during use, thus making the walker 10 more stable during use.

[0044] See also Figure 4 , Figure 4 An exploded view of a portion of the structure of a walking aid provided in some embodiments of this application.

[0045] In some embodiments, the second connecting frame 600 includes a first connecting rod 610, a second connecting rod 620, and a fifth connecting member 630. The fifth connecting member 630 has a receiving groove 631 on the side facing the wheel body 400. One end of the first connecting rod 610 is received in the receiving groove 631 and rotatably connected to the fifth connecting member 630, and the other end of the first connecting rod 610 is rotatably connected to the first bracket 100. One end of the second connecting rod 620 is received in the receiving groove 631 and rotatably connected to the fifth connecting member 630, and the other end of the second connecting rod 620 is rotatably connected to the second bracket 200.

[0046] By providing a receiving groove 631 on the side of the fifth connecting member 630 facing the wheel body 400, one end of the first connecting rod 610 is received in the receiving groove 631 and rotatably connected to the fifth connecting member 630, and the other end of the first connecting rod 610 is rotatably connected to the first bracket 100; one end of the second connecting rod 620 is received in the receiving groove 631 and rotatably connected to the fifth connecting member 630, and the other end of the second connecting rod 620 is rotatably connected to the second bracket 200, so that when the fifth connecting member 630 is subjected to a force in the same direction as gravity, the first connecting rod 610 and the second connecting rod 620 can rotate relative to the fifth connecting member until the first connecting member 630 rotates. The axes of the connecting rod 610 and the second connecting rod 620 are basically on the same straight line. When the walker 10 is fully opened and subjected to a force in the first direction X after the walker 10 is opened, the first bracket 100 and the second bracket 200 are not easy to get close to each other due to the limiting of the first connecting rod 610 and the fifth connecting member 630 and the limiting of the second connecting rod 620 and the fifth connecting member 630. The walker 10 has high stability during use. When the fifth connecting member 630 is subjected to a force opposite to the direction of gravity, the first connecting rod 610 and the second connecting rod 620 can get close to each other until they fit together, and the walker 10 is fully closed.

[0047] See Figure 1 In some embodiments, the first bracket 100 includes a first support rod 110 and a second support rod 120. One end of the first support rod 110 is connected to the second support rod 120, and the other end of the first support rod 110 is spaced apart from the second support rod 120 along a second direction Y. A first connecting rod 610 is connected to the first support rod 110. The second connecting frame 600 includes a first movable rod 640. One end of the first movable rod 640 is rotatably connected to the first connecting rod 610, and the other end of the first movable rod 640 is rotatably connected to the second support rod 120.

[0048] By connecting one end of the first support rod 110 to the second support rod 120, and the other end of the first support rod 110 and the second support rod 120 spaced apart along the second direction Y, the stability of the first bracket 100 is relatively high. By rotatably connecting one end of the first movable rod 640 to the first connecting rod 610, and the other end of the first movable rod 640 to the second support rod 120, the first movable rod 640 can support the second support rod 120, making the stability of the first bracket 100 even higher. Furthermore, the first support rod 110 and the second support rod 120 can rotate relative to each other to open or close, making the space occupied by the walker 10 smaller when closed.

[0049] In some embodiments, the second bracket 200 includes a third support rod 210 and a fourth support rod 220. One end of the third support rod is connected to the fourth support rod 220, and the other end of the third support rod 210 is spaced apart from the fourth support rod 220 along a second direction Y. The second connecting rod 620 is connected to the third support rod 210. The second connecting frame 600 includes a second movable rod 650. One end of the second movable rod 650 is rotatably connected to the second connecting rod 620, and the other end of the second movable rod 650 is rotatably connected to the fourth support rod 220.

[0050] By connecting one end of the third support rod 210 to the fourth support rod 220, and the other end of the third support rod 210 to the fourth support rod 220 at a distance along the second direction Y, the stability of the second bracket 200 is improved. By rotatably connecting one end of the second movable rod 650 to the second connecting rod 620, and the other end of the second movable rod 650 to the fourth support rod 220, the second movable rod 650 can support the fourth support rod 220, making the stability of the second bracket 200 even higher. Furthermore, the third support rod 210 and the fourth support rod 220 can rotate relative to each other to open or close, making the space occupied by the walker 10 smaller when closed.

[0051] In some embodiments, the first direction X is perpendicular to the second direction Y.

[0052] In some embodiments, the first bracket 100 includes a third movable rod 130, the two ends of which are rotatably connected to the first support rod 110 and the second support rod 120, respectively.

[0053] By rotatably connecting the two ends of the third movable rod 130 to the first support rod 110 and the second support rod 120 respectively, the third movable rod 130 can support the first support rod 110 and the second support rod 120, thereby increasing the stability of the first bracket 100. Furthermore, the first support rod 110 and the second support rod 120 can rotate relative to the third connecting rod 660 to open or close.

[0054] In some embodiments, the second bracket 200 includes a fourth movable rod 230, the two ends of which are rotatably connected to the third support rod 210 and the fourth support rod 220, respectively.

[0055] By rotatably connecting the two ends of the fourth movable rod 230 to the third support rod 210 and the fourth support rod 220 respectively, the fourth movable rod 230 can support the third support rod 210 and the fourth support rod 220, thereby increasing the stability of the second bracket 200. Furthermore, the third support rod 210 and the fourth support rod 220 can rotate relative to the fourth connecting rod 670 to open or close.

[0056] See Figures 5 to 7 , Figure 5 A three-dimensional structural schematic diagram of the walking aid provided in the open state from one perspective for some other embodiments of this application; Figure 6 A three-dimensional structural diagram of the walking aid in a folded state provided for other embodiments of this application; Figure 7 This is a three-dimensional structural diagram of the walking aid provided in some other embodiments of this application in the open state.

[0057] In some embodiments, the first bracket 100 includes a first support rod 110 and a second support rod 120, the first support rod 110 and the second support rod 120 being spaced apart along a second direction Y; the second bracket 200 includes a third support rod 210 and a fourth support rod 220, the third support rod 210 and the fourth support rod 220 being spaced apart along a second direction Y.

[0058] By arranging the first support rod 110 and the second support rod 120 at intervals along the second direction Y, and the third support rod 210 and the fourth support rod 220 at intervals along the second direction Y, an accommodating space can be formed between the first support rod 110, the second support rod 120, the third support rod 210, and the fourth support rod 220, which can be used to place a seat cushion to support the user.

[0059] In some embodiments, the walker 10 includes a plurality of first connecting frames 300, one of which is connected between a first support rod 110 and a third support rod 210, and another of which is connected between a second support rod 120 and a fourth support rod 220.

[0060] By connecting one of the multiple first connecting frames 300 between the first support rod 110 and the third support rod 210, and connecting one of the multiple first connecting frames 300 between the second support rod 120 and the fourth support rod 220, the walking aid 10 can be opened or closed in the first direction X. This makes the walking aid 10 occupy less space when closed. Furthermore, setting multiple first connecting frames 300 can further reduce the possibility of jamming during the opening or closing process of the walking aid 10, making the walking aid 10 more convenient to use and reducing wear and tear, which helps to extend the service life of the walking aid 10.

[0061] In some embodiments, the first direction X is perpendicular to the second direction Y.

[0062] In some embodiments, one of the plurality of first connecting frames 300 is connected between the first support rod 110 and the second support rod 120, and one of the plurality of first connecting frames 300 is connected between the third support rod 210 and the fourth support rod 220.

[0063] By connecting one of the multiple first connecting frames 300 between the first support rod 110 and the second support rod 120, and connecting one of the multiple first connecting frames 300 between the third support rod 210 and the fourth support rod 220, the walking aid 10 can be opened or closed in the first direction X and the second direction Y. This makes the walking aid 10 occupy less space when closed. Furthermore, the multiple first connecting frames 300 further reduce the possibility of jamming during the opening or closing process of the walking aid 10, making the walking aid 10 more convenient to use and reducing wear and tear, which helps to extend the service life of the walking aid 10.
