[0037] As Figure 1 As shown in the utility model provides a kind of walking auxiliary device, including bottom frame 100, front support 200, rear support 300, side baffle 400, clamping assembly 500, bag belt 600.

[0038] The lower bottom surface of the bottom frame 100 is provided with a walking wheel 110; the front support 200 and the rear support 300 are respectively hinged to the bottom frame 100 through connecting shafts 120, and the axes of the two connecting shafts 120 are arranged in parallel; the side baffle 400 is symmetrically provided with two, and when the front support 200 and the rear support 300 are opposite and parallel, the side baffle 400 is connected to the opposite sides of the front support 200 and the rear support 300 respectively; the clamping assembly 500 is arranged on the side baffle 400, so as to clamp and connect the side baffle 400 to the opposite sides of the front support 200 and the rear support 300 respectively; and the two ends of the bag belt 600 are connected to the ends of the front support 200 and the rear support 300 away from the bottom frame 100 respectively, and the bag belt 600 is made of elastic material.

[0039] The walking auxiliary device provided by the embodiment can significantly improve the walking convenience and safety of patients or the elderly when they use it. Specifically, the user can first put his / her legs into the bottom frame 100 and position himself / herself between the front support 200 and the rear support 300. Then, through the clamping assembly 500, the two side baffles 400 can be connected to the front support 200 and the rear support 300 respectively to form a stable fence structure. This design aims to effectively avoid the risk of falling due to loss of balance during walking, thereby ensuring the safety of the user.

[0040] Further, the design of the bag belt 600 provides additional support for the user. By putting the bag belt 600 through the crotch and fixing the two ends of the bag belt 600 on the front support 200 and the rear support 300 respectively, the bag belt 600 can provide a certain lifting force to the user. This lifting force not only helps to reduce the walking burden of the user, but also makes the walking process more relaxed and easy.

[0041] When the user walks, the walking wheel 110 below the bottom frame 100 will roll with the movement of the pace, so that the whole walking auxiliary device can move with the user. This design not only improves the convenience of use, but also makes the device flexible and adaptable to various walking environments.

[0042] When the utility model is not used, its convenient installation and disassembly characteristics are also fully embodied. The user can first remove the bag belt 600, and then separate the two side baffles 400 from the front support 200 and the rear support 300 through the clamping assembly 500. Finally, through the hinged cooperation of the connecting shafts 120, the front support 200 and the rear support 300 can be folded relative to the bottom frame 100, thereby greatly reducing the space occupied by the device. The characteristics of simple operation, easy storage and transportation make the embodiment have high practicality and convenience in actual application.

[0043] Combination Figure 2 , Figure 3 As shown, in some specific embodiments, one end of the side baffle 400 has a bent portion 410, and the other end of the side baffle 400 opposite to the bent portion 410 is provided with a connecting post 420. The front bracket 200 has a connecting hole 210 corresponding to the connecting post 420, and the connecting post 420 passes through the connecting hole 210. The snap-fit ​​assembly 500 is disposed on the bent portion 410, and the bent portion 410 is connected to the end face of the rear bracket 300 opposite to the front bracket 200 through the snap-fit ​​assembly 500. The side baffle 400 is connected to the front bracket 200 and the rear bracket 300 respectively through two directions (i.e., the connection between the connecting post 420 and the front bracket 200 and the snap-fit ​​between the bent portion 410 and the rear bracket 300), which not only facilitates quick assembly and disassembly but also ensures the installation reliability of the side baffle 400. This design not only improves the practicality and convenience of the walking assistance device but also brings a safer and more comfortable walking experience to the user.

[0044] like Figure 4 As shown, in some specific embodiments, the snap-fit ​​assembly 500 includes a rotating shaft 510 and a snap-fit ​​member 520. The rotating shaft 510 passes through the bent portion 410. The snap-fit ​​member 520 is specifically rectangular or polygonal in shape and is located at the end of the rotating shaft 510 near the rear support 300. The rear support 300 has a snap-fit ​​hole 310 that matches the shape of the snap-fit ​​member 520. A pre-tightening member 530 is provided between the end of the rotating shaft 510 away from the rear support 300 and the end face of the bent portion 410 away from the rear support 300. In actual operation, the user only needs to press the rotating shaft 510 to compress the pre-tightening member 530 and drive the snap-fit ​​member 520 through the snap-fit ​​hole 310. Subsequently, the user rotates the rotating shaft 510 to misalign the snap-fit ​​member 520 with the snap-fit ​​hole 310. At this point, the rotating shaft 510 is released, and under the action of the pre-tightening member 530, the snap-fit ​​member 520 will achieve a pre-tight fit with the rear bracket 300. This operation process is not only simple and quick, but also ensures the reliability and stability of the connection between the snap-fit ​​member 500 and the rear bracket 300.

[0045] In some specific embodiments, the upper end of the front bracket 200 is provided with a front support plate 220, and the upper end of the rear bracket 300 is provided with a rear support plate 320; the design of these two support plates fully takes into account the actual needs and user experience of the user.

[0046] The front support plate 220 and the rear support plate 320 provide a stable handhold for the user when stepping into or out of the base frame 100. This design not only reduces the difficulty of operating this embodiment but also greatly improves ease of use and comfort. In actual use, the user can easily grasp the front support plate 220 or the rear support plate 320 to maintain balance and stability, thus completing the stepping-in or stepping-out action more smoothly.

[0047] Furthermore, the front support plate 220 and the rear support plate 320 also have a certain load-bearing capacity, providing effective assistance when the user needs to temporarily support their body weight. This design further enhances the practicality and safety of this embodiment, enabling it to better meet the user's needs.

[0048] like Figure 5 As shown, in some specific embodiments, one end of the pocket 600 is fixedly connected to the lower end face of the front support plate 220, and the other end of the pocket 600 away from the front support plate 220 is connected to the lower end face of the rear support plate 320 through a quick-release assembly 700. In practical applications, when it is necessary to quickly remove the restriction of the pocket 600 on the user, the user only needs to operate the quick-release assembly 700 to easily remove the pocket 600 from the rear support plate 320 without having to perform cumbersome unlocking or disassembly steps.

[0049] This design not only greatly improves the ease of use of the Pocket 600, but also enables it to respond quickly in emergencies, providing users with timely relief. For example, in situations requiring rapid evacuation or emergency rescue, users can quickly remove the Pocket 600's restrictions for greater flexibility in action and response.

[0050] In some specific embodiments, the quick-release assembly 700 includes a connecting seat 710 and a connector 720. The connecting seat 710 is disposed on the lower end face of the rear support plate 320, and the end face of the connecting seat 710 opposite to the front support plate 220 has a connector hole 711. The connector 720 is fixedly connected to the pocket strap 600, and the connector 720 passes through the connector hole 711. This design ensures that when the pocket strap 600 is subjected to traction, the connector 720 can move accordingly and form a tighter fit with the connector hole 711. Specifically, when the pocket strap 600 is subjected to the user's traction force, the connector 720 will be more tightly embedded in the connector hole 711 under the action of force, thereby enhancing the connection stability between the pocket strap 600 and the rear support plate 320.

[0051] More ingeniously, this plug-in connection not only ensures the reliability of the connection, but also makes the disassembly of the plug-in part 720 extremely simple. In actual operation, the user only needs to apply a certain external force to easily pull out the plug-in part 720 from the plug-in hole 711, thereby achieving the quick disassembly of the sling 600.

[0052] In some specific embodiments, the upper side wall in the plug-in hole 711 is provided with a pre-tightening groove 712, and the upper side wall of the plug-in part 720 is provided with a pre-tightening boss 721; in actual application, when the sling 600 is subjected to the downward traction force of the user, the plug-in part 720 will produce a certain upward deflection in the plug-in hole 711. This deflection enables the pre-tightening boss 721 to accurately fall into the pre-tightening groove 712, thereby achieving further reinforcement between the plug-in part 720 and the plug-in hole 711.

[0053] This reinforcement mechanism not only greatly improves the connection reliability between the sling 600 and the rear support plate 320, but also makes the entire connection structure more stable and safe when subjected to external forces. Even in extreme cases, such as when the user is suddenly impacted or needs to move quickly, the sling 600 can remain stable, providing continuous support and protection to the user.

[0054] When the cooperation between the plug-in part 720 and the plug-in hole 711 needs to be released, the operation is also simple and fast. The user only needs to relax the sling 600, and the plug-in part 720 will naturally fall under the action of gravity, causing the pre-tightening boss 721 to smoothly escape from the pre-tightening groove 712. Subsequently, the user can easily pull out the plug-in part 720 from the plug-in hole 711, completing the disassembly of the sling 600.

[0055] In some specific embodiments, the connection end of the plug-in part 720 and the sling 600 is provided with a bend, which is arranged on the edge of the plug-in hole 711, to reduce the wear caused by the contact between the sling 600 and the edge of the plug-in hole 711, thereby prolonging the service life of the sling 600.

[0056] In some specific embodiments, the front support plate 220 or the rear support plate 320 is provided with a level 221 and an alarm 222, and the level 221 is electrically connected to the alarm 222; this design enables the level 221 to immediately send a signal to the alarm 222 when it detects that the device is tilted. After receiving the signal, the alarm 222 will quickly start and emit a warning sound or flashing light as an obvious prompt signal.

[0057] Further, the alarm 222 is also equipped with a communication function with the user's family or caregivers. When the alarm 222 is activated, it will send an alarm signal to the user's family or caregivers in a timely manner through a pre-set communication method, such as mobile phone message, phone call, or APP push, etc. In this way, even if the user encounters an emergency situation while using the device, the family or caregivers can know about it in the first time and take action quickly to provide timely help and support for the user.

[0058] In summary, by setting the level 221 and the alarm 222 on the front support plate 220 or the rear support plate 320 and realizing the electrical connection of the two, a safe and convenient protection mechanism is provided for the user. This design not only improves the safety performance of the device, but also provides timely communication means for the user's family or caregivers, so that they can respond and handle quickly in an emergency situation.

[0059] Of course, in other embodiments of the present application, a call button can also be provided on the front support plate 220 to facilitate the user to call the family or caregivers directly, ensuring the safety of the user.

[0060] In some specific embodiments, the bottom frame 100 is provided with a forward and reverse motor 130 corresponding to the connecting shaft 120, which is used to drive the front support 200 or the rear support 300 to fold relative to the bottom frame 100, facilitating the automatic folding of the present embodiment.

[0061] In some specific embodiments, the upper end of the front support 200 is provided with a handrail 230, and the handrail 230 specifically comprises two; in actual application, when the user uses the present embodiment to walk, they can hold the handrail 230 very conveniently, thereby maintaining the balance and stability of the body. This design not only improves the walking safety of the user, but also enables them to be more confident and composed during walking.

[0062] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
