DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides Figure 1 and Figure 2 The intelligent auxiliary walking device shown in the figure includes a front connecting cross bar 1, and the left and right ends of the front connecting cross bar 1 are fixedly connected to side frames 2. The two side frames 2 are connected to each other through the front connecting cross bar 1, and are pushed on the ground through two steering mechanisms 3 and two moving wheels 4 at the lower ends. The steering mechanism 3 is composed of a steering machine on the side close to the front connecting cross bar 1 and a steering wheel on the side far away from the front connecting cross bar 1. The steering wheel is connected to the side frame 2 through the steering machine, so that the front end of the side frame 2 can be steered through the steering mechanism 3. The support handle 6 is set in a "U" shape, so that the user can enter between the two side frames 2 through the rear end of the support handle 6 and be located inside the support handle 6. The user can support the body by holding the left and right sides of the support handle 6, and the front end of the support handle 6 is connected to the front connecting cross bar 1 through the upper support rod 5, and the lower end is connected to the side frames 2 on both sides through two rear support rods 7, so that the support handle 6 can stably support the user's body, so that the user can walk with assistance through the auxiliary walking device.

[0030] Preferably, a lower support rod 8 is fixedly connected at the center of the lower end of the front connecting cross bar 1, and a seat frame 9 is provided at the lower end of the lower support rod 8. A cushion 10 is sleeved on the rear outer side of the seat frame 9, so that the user can rest by sitting on the cushion 10 sleeved on the rear outer side of the seat frame 9 when tired, and the seat frame 9 and the cushion 10 are connected to the center of the lower end of the front connecting cross bar 1 through the lower support rod 8, so that the seat frame 9 and the cushion 10 are located between the legs of the user when walking, and do not hinder the user's walking.

[0031] Preferably, the two side frames 2 are rotatably connected to an opening link 11 at the center of one end away from the front connecting cross bar 1, and the lower ends of the two opening links 11 are rotatably connected to a side support mechanism 12. When the auxiliary walking device tilts, the side support mechanisms 12 on both sides can be opened in the tilting direction through the rotation of the opening link 11, and support the tilted side of the auxiliary walking device to prevent the user from falling, and after the auxiliary walking device is straightened, the opening link 11 and the side support mechanism 12 will return to their original positions and will not form obstacles on the sides of the auxiliary walking device.

[0032] like Figure 3 As shown, an opening groove 13 is provided at the center of the lower end of the side frame 2, and an opening sleeve 14 is rotatably connected inside the opening groove 13. An opening slide rod 15 is slidably connected inside the lower end of the opening slide rod 14, and the opening slide rod 15 is rotatably connected to the lower side of the opening connecting rod 11 close to the end of the side frame 2. The side support mechanism 12 is composed of a support wheel and a steering support frame, and the support wheel of the side support mechanism 12 is always in contact with the ground. When the auxiliary walking device rolls, the side support mechanism 12 is turned through the steering support frame under the pressure of the rolling force and rolls in the tilting direction. At the same time, the opening connecting rod 11 drives the opening slide rod 15 to rotate inside the opening slide sleeve 14. The side support mechanism 12 stops rolling and supports the tilting side of the auxiliary walking device, so that the opening link 11 and the side support mechanism 12 can be opened in the tilting direction when the auxiliary walking device tilts, and form a support to prevent the auxiliary walking device from continuing to tilt, thereby preventing the user from falling.

[0033] Preferably, the opening slide rod 15 is externally sleeved with a side-pull spring 16, and the side-pull spring 16 is located inside the opening sleeve 14. The opening slide rod 15 is elastically connected to the lower end of the opening sleeve 14 through the side-pull spring 16. After the auxiliary walking device returns to the normal position, the opening slide rod 15 shrinks back into the opening sleeve 14 under the action of the side-pull spring 16, thereby allowing the opening connecting rod 11 and the side support mechanism 12 to return to their original positions, avoiding the formation of obstacles on the side of the auxiliary walking device.

[0034] like Figure 4 and Figure 5As shown, a telescopic rod 17 is fixedly connected to the front side of the upper end of the seat frame 9, and the telescopic rod 17 is slidably connected to the inner center of the lower end of the lower support rod 8, and a square limit slider 18 is fixedly connected to the top of the telescopic rod 17. A return spring 19 is sleeved on the outside of the telescopic rod 17, and the return spring 19 is located at the lower end of the limit slider 18. The telescopic rod 17 and the limit slider 18 are elastically connected to the lower end of the lower support rod 8 through the return spring 19. When the user sits on the upper end of the seat cushion 10, the seat cushion 10 and the seat frame 9 move downward at the lower end of the lower support rod 8 through the telescopic rod 17, and the lower end of the seat frame 9 is pressed tightly against the ground. At the same time, the seat frame 9 and the seat cushion 10 are connected to the lower support rod 8 through the front cross bar 1 and the lower support rod 8. The support rod 8 is connected to the side frames 2 on both sides, so that the seat frame 9 and the seat cushion 10 can support the user through the side frames 2 on both sides, and the lower end of the seat frame 9 is pressed tightly against the ground to limit the movement of the side frames 2 on both sides, so that when the user sits down, the auxiliary walking device will not move and can stably support the user, and when the user stands up, the seat frame 9 and the seat cushion 10 can return to their original positions through the limiting slider 18 and the return spring 19, so that the auxiliary walking device can move, and the square limiting slider 18 can limit the orientation of the seat frame 9 and the seat cushion 10, and will not rotate with the lower support rod 8, so that the seat frame 9 and the seat cushion 10 are always located between the legs of the user.

[0035] like Figure 4 and Figure 6 As shown, an inflatable airbag 20 is provided inside the upper side of the seat cushion 10, and the inflatable airbag 20 is located on the upper side of the seat frame 9. Since the seat cushion 10 is made of elastic material, when the user sits on the upper end of the seat cushion 10, the user will squeeze the inflatable airbag 20 inside the upper end of the seat cushion 10, so that the internal space of the inflatable airbag 20 becomes smaller, and since the upper and lower ends of the inflatable airbag 20 are squeezed by the user and the seat frame 9 respectively, the gas inside the inflatable airbag 20 will flow to the four sides. Under the squeezing of the gas, the seat cushion 10 will be deformed and expand to the four sides, thereby expanding the contact area between the user and the upper end of the seat cushion 10, and the seat cushion 10 can elastically support the user through the gas inside the inflatable airbag 20, so that the user can sit more comfortably.

[0036] Preferably, extrusion plates 21 are clamped inside the inner walls of the upper and lower ends of the expansion airbag 20, and multiple spring grooves are opened inside the opposite ends of the two extrusion plates 21. Multiple restoring springs 22 are arranged between the two extrusion plates 21, and the upper and lower ends of the multiple restoring springs 22 are respectively located inside the spring grooves opened inside the two extrusion plates 21. When the user stands up, the upper end of the expansion airbag 20 will rebound upward under the action of the extrusion plate 21 and the restoring spring 22, and the internal space of the expansion airbag 20 is restored, allowing the gas expanded to the four sides of the seat cushion 10 to flow back into the expansion airbag 20 under the elastic action of the seat cushion 10, and at the same time the seat cushion 10 returns to its original state, allowing the left and right sides of the seat cushion 10 to shrink back to their original positions without hindering the user's walking.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
