[0052] Example 1: Figure 1-3 As shown in the figure, a patient walking assist device includes a walking frame 1, a front baffle 2 and a seat 3
[0053] For the walking frame 1, a moving wheel 102 is provided at the bottom of the walking frame 1, and the moving wheel 102 is provided with a brake clamp 103, and a handrail 104 is provided at the top of the walking frame 1, and a brake handle 105 is installed at the handrail 104 for active braking operation;
[0054] In this embodiment, reference Figure 1 As shown, the walking frame 1 is in a U shape and has two parallel side panels 101. A pair of moving wheels 102 are arranged under each side panel 101, and each side panel 101 is connected to the moving wheels 102 through an arc rod 107, so that a certain space support is formed in front and rear of the walking frame 1, thereby improving the supporting effect of the walking frame 1 in front and rear. Figure 1 As shown, an auxiliary handle 106 is provided at the side of the U-shaped opening, so that the patient can use the handle to stand up from the side.
[0055] The front baffle 2 is configured to form a shield in front of the patient's traveling direction;
[0056] The seat 3 is movably mounted on the walking frame 1 and is located behind the patient's traveling direction;
[0057] In some embodiments, the seat 3 is connected to the walking frame 1 via a connecting rod 303, one end of the connecting rod 303 is movably connected to the walking frame 1, and the seat 3 is driven to move toward or away from the rear of the patient's travel direction by the swing of the connecting rod 303.
[0058] In this embodiment, reference Figure 1 and Figure 3 As shown, the seat 3 includes a first seat part 301 and a second seat part 302, and the first seat part 301 and the second seat part 302 are respectively connected to the two side panels 101 through a connecting rod 303. As the two connecting rods 303 swing, the first seat part 301 and the second seat part 302 are driven to approach each other and be located behind the patient's travel direction, or to move away from each other and close to the corresponding side panels 101. Compared with a single seat, the seat 3 is divided into two parts in this embodiment, thereby reducing the rotation angle of each part, better triggering the formation of the seat 3, and better resetting for hiding.
[0059] As for the linkage between the front baffle 2 and the seat 3, wherein the front baffle 2 is slidably installed on the walking frame 1 along the traveling direction, a first linkage member 4 is provided between the front baffle 2 and the seat 3, at least when the front baffle 2 slides in the traveling direction, the seat 3 is synchronously driven to move to the rear of the patient's traveling direction.
[0060] In this embodiment, reference Figure 4-Figure 6As shown, a rack 21 is installed on the front baffle 2; the first linkage member 4 includes a linkage gear 401 and a connecting shaft 402, the linkage gear 401 is meshed with the rack 21, and drives the linkage gear 401 to rotate as the rack 21 moves; the connecting shaft 402 connects the linkage gear 401 and one end of the connecting rod 303, and drives the connecting rod 303 to swing around the connecting shaft 402 as the linkage gear 401 rotates.
[0061] Among them, reference Figure 1 As shown, both side panels 101 are provided with slide grooves 5 for the front baffle 2 to slide. As the front baffle 2 moves along the slide grooves 5, the rack 21 located below it can be driven to slide, and the rack 21 meshes with the linkage gear 401, thereby driving the linkage gear 401 to rotate. The rotation of the linkage gear 401 can drive the rotating shaft connected to it to rotate, and as it rotates, it can synchronously drive the connecting rod 303 connected to it to swing, thereby driving the seat 3 to move synchronously, thereby forming the above-mentioned movement of the seat 3 synchronously with the movement of the front baffle 2, and after the front baffle 2 slides to the specified position, it is fixed by, for example, setting a locking screw 3032 or a latch and other structures. Due to the meshing action, the state of the rear seat 3 can be locked. After unlocking the front baffle 2, moving the seat 3 backward to push the seat 3 can drive the front baffle 2 to reset, and the operation is more flexible and convenient.
[0062] Embodiment 2: In addition to the above structure, in this embodiment, an anti-sliding block 6 is provided at the bottom end of the walking frame 1; and the connecting shaft 402 is arranged in the vertical direction, and includes an inner shaft 4021 and an outer shaft 4022, one end of the inner shaft 4021 is connected to the linkage gear 401; the outer shaft 4022 is coaxially sleeved on the inner shaft 4021, and rotates synchronously with the inner shaft 4021, and can move along the axis direction of the inner shaft 4021; one end of the connecting rod 303 is sleeved on the outer shaft 4022 through a sleeve 3031, and a locking screw 3032 is provided on the sleeve 3031, and the locking screw 3032 is used to lock or unlock the state of the sleeve 3031 and the outer shaft 4022, and in the unlocked state, the sleeve 3031 moves along the axis direction of the outer shaft 4022, which is used to adjust the position of the connecting rod 303, so that the height of the seat 3 can be adjusted according to the needs of different patients;
[0063] A receiving tube 601 is provided at the top of the anti-sliding block 6, and an adjusting member 7 is provided between the receiving tube 601 and the outer shaft 4022. The adjusting member 7 is configured to control the contact or separation between the receiving tube 601 and the end of the outer shaft 4022, and when in contact, the receiving tube 601 is synchronously driven downward as the outer shaft 4022 moves downward, so that the anti-sliding block 6 contacts the ground; and elastic members 8 are provided on both the receiving tube 601 and the outer shaft 4022, and the two elastic members 8 are respectively configured to drive the receiving tube 601 and the outer shaft 4022 to move upward.
[0064] refer to Figure 4-Figure 6As shown, when the seat 3 is combined and located behind the patient in the working state through the above operation, when the patient collapses, on the one hand, the seat 3 is used to support the patient from collapsing on the ground, and on the other hand, the force exerted on the seat 3 by the patient when collapsing can drive the seat 3 to apply force downward, thereby driving the sleeve 3031 and the outer shaft 4022 to move downward along the inner shaft 4021, and through the action of the adjusting member 7, the receiving tube 601 is in contact with the end of the outer shaft 4022. At this time, the outer shaft 4022 overcomes the downward movement of the elastic member 8 and applies force to the receiving tube 601. The receiving tube 601 overcomes the downward movement of the elastic member 8, thereby driving the anti-sliding block 6 to move downward and contact the ground, increasing the friction with the ground, and avoiding the sliding of the walker 1 caused by the failure to brake in time due to the sudden collapse, thereby further improving the safety of use.
[0065] For the setting of the adjusting member 7, refer to Figure 6 As shown, the receiving tube 601 is a hollow structure, and the inner diameter is larger than the outer diameter of the outer shaft 4022. The adjusting member 7 includes a movable middle plate 701, and a hole 702 with a hole diameter not less than the inner diameter of the hollow is arranged on the middle plate 701. With the movement of the middle plate 701, the hole 702 can overlap or separate with the top of the receiving tube 601. When overlapping, the outer shaft 4022 moves downward and can pass through the hole 702 to enter the inside of the receiving tube 601, so that no force is generated with the receiving tube 601. At this time, the receiving tube 601 will not move downward. When the hole 702 separates from the top of the receiving tube 601, the outer shaft 4022 moves downward, and synchronously drives the lower part through the middle plate 701. The receiving tube 601 moves downward. For the setting of the middle plate 701, it can move along the moving direction of the outer shaft 4022, and can also be adjusted and moved in a direction perpendicular to the moving direction of the outer shaft 4022. For the operation of the middle plate 701, a dial plate 703 can be set on the side plate 101. The dial plate 703 and the middle plate 701 can be directly connected by magnetic adsorption, or other connection methods can be adopted that can not affect the up and down movement of the middle plate 701 and can drive the center plate to move vertically up and down through the dial plate 703. The receiving tube 601 and the middle plate 701 can be driven to reset through the elastic member 8. At this time, the state of the middle plate 701 can be adjusted through the dial plate 703. For the elastic member 8, refer to Figure 4-Figure 6 As shown, a spring member may be employed.
[0066] In some embodiments, reference Figure 6 As shown, a plurality of slots 602 are provided at one end of the anti-slip block 6 facing the ground, and an anti-slip sheet 603 is provided in each slot 602.

[0068] Among them, by the cooperation between the rotating rod 10 and the front baffle 2, when the patient leans forward, the front baffle 2 can be driven to rotate at a certain angle by the forward leaning force, and the retractor 11 can be driven to retract by the rotation, so that the brake wire 12 controls the brake clamp 103 to brake, forming a certain braking, solving the problem of the walking frame 1 sliding due to the patient leaning forward too suddenly and failing to brake in time, and further improving the safety and stability of use.
[0069] In addition, refer to Figure 4 As shown, a protrusion 13 is provided on the rotating rod 10, and an elastic block 14 is provided on the slider 9 at a position corresponding to the protrusion 13. The elastic block 14 contacts the protrusion 13 and is configured to prevent the rotating rod 10 from rotating before its own elastic deformation, so as to avoid braking caused by the rotation of the front baffle 2 due to a collision in normal circumstances.
