Description

Technical Field

[0001] This invention relates to the field of walking assistance exercise technology, and specifically to a walking assistance exercise device. Background Technology

[0002] To assist the body in supporting its weight, maintaining balance, and walking, patients often use handrails in the corridor to walk slowly during their recovery period in order to speed up the recovery process. However, the handrails currently in use are generally installed on the walls of hospital corridors, so patients usually hold onto the handrail with one hand, making it difficult for them to walk steadily and increasing the risk of falls. Therefore, walking assistance devices are usually used during the recovery period.

[0003] For example, patent CN115444721A discloses a fall-resistant walking aid for elderly rehabilitation, relating to the field of rehabilitation care. It includes a base with four support rods fixedly mounted on the top, and two fixing plates fixedly mounted on the top of each support rod. This fall-resistant walking aid for elderly rehabilitation is hung in a hook via a ring. The elderly person sits on a support cushion, which provides support when they are exhausted, allowing them to sit down and rest temporarily. During walking exercises, the straight support rods and straight casters provide lateral support, preventing the elderly person from tilting to the side. The support cushion and backrest rollers provide support in case of a fall, preventing injury. In this technical solution, to prevent lateral tilting, straight support rods and straight casters are installed on both sides of the walking aid to widen the bottom of the device, thus preventing tilting.

[0004] It is evident that in the existing technology, in order to prevent the walking aid exercise device from deviating to the side, the width of the bottom ends on both sides of the walking aid exercise device is usually widened. However, after widening the bottom ends on both sides of the walking aid exercise device, the footprint is increased, which often affects pedestrians when patients use the walking aid exercise device to walk in narrow areas such as corridors. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that the bottom sides of the existing walking assistance exercise device are relatively fast, which often affects pedestrians when patients use the walking assistance exercise device to walk in narrow areas such as corridors.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a walking assistance exercise device, comprising:

[0007] The supporting frame is equipped with multiple casters.

[0008] An extension mechanism, mounted on the support frame, extends to opposite sides of the support frame to widen the support frame chassis; and

[0009] The tilt sensor can sense the tilt angle of the support frame to control the extension mechanism's extension.

[0010] In this invention, the patient enters the support frame, supports their body by holding onto the frame, and uses multiple casters to move the frame, thus assisting in walking exercises and accelerating the recovery speed of the patient's lower limbs. When the patient's body shifts and causes the support frame to tilt, the tilt sensor detects the tilt and controls the extension mechanism to extend to both sides in the width direction of the support frame, widening the height of the support frame chassis. This provides support when the support frame tilts, effectively preventing the patient from falling and getting injured when the support frame tilts. Furthermore, the extension mechanism effectively reduces the width of the support frame, minimizing the impact on pedestrians when the patient exercises in narrow areas such as corridors.

[0011] Preferably, the extension mechanism includes a lead screw, a nut seat, a support column, and a motor; the lead screw is rotatably mounted on the support frame, and nut seats are respectively installed at both ends of the lead screw, with the threads of the two nut seats having opposite directions; the support column corresponds one-to-one with the nut seat, the support column is slidably mounted on the support frame, and is fixedly connected to the nut seat; the motor can drive the lead screw to rotate, and the tilt angle sensor can control the motor's operation.

[0012] Once the tilt sensor detects that the support frame is tilted, it controls the motor to rotate. The motor drives the lead screw to rotate, which in turn causes the two nut seats to slide in opposite directions. The nut seats then cause the support columns to slide in opposite directions, thereby extending the support frame to both sides in the width direction and effectively preventing the support frame from tipping over.

[0013] Preferably, two extension mechanisms are respectively provided along the length of the support frame; each universal wheel corresponds to a support column, and the universal wheel includes a rack, a threaded shaft, a gear, a tripod, a roller, and a brake plate; the rack is arranged along the sliding direction of the support column and is fixedly connected to the support column; the threaded shaft is vertically arranged and threadedly connected to the support frame; the gear is coaxially fixed with the threaded shaft, and the gear meshes with the rack; the tripod is rotatably mounted on the lower end of the threaded shaft; the roller is mounted on the tripod; the brake plate is located above the roller and below the support frame, and the lower end of the brake plate is hinged to the tripod. This allows the support frame to stop moving when tilted, thereby effectively preventing the support frame from moving spontaneously while tilted and potentially knocking over the patient.

[0014] Preferably, the swivel wheel also includes a spring, which is mounted on the triangular plate and applies a spring force to the brake plate away from the roller. By applying a spring force to the brake plate away from the roller, a certain gap is maintained between the brake plate and the roller when the patient is exercising, reducing the contact time with the roller and improving the service life of the brake plate.

[0015] Preferably, a brake pad is installed on the side of the brake plate closest to the roller. The brake pad increases the friction between the brake plate and the roller, thus making it easier to restrict the rotation of the roller.

[0016] Preferably, a crash block is installed at the end of the support column away from the lead screw. The crash block can effectively prevent the support column from hitting and injuring pedestrians when it extends outward.

[0017] Preferably, a counterweight is installed at the end of the support column away from the lead screw. The counterweight increases the weight of the support frame, thereby increasing the intensity of the patient's walking assistance exercises. Furthermore, by placing counterweights at both ends, if the support frame tilts, the counterweight at the other end applies a downward force to further prevent the support frame from tipping over.

[0018] Preferably, the tilt sensing element is a tilt sensor. The tilt sensor senses the angle of tilt of the support frame.

[0019] Preferably, the support frame includes uprights, connecting columns, a support plate, and a sealing plate; two uprights are arranged parallel to each other, and the two sides of their lower ends are fixedly connected by the connecting columns; one side of the upper ends of the two uprights is fixedly connected by the support plate; the sealing plate is located on the other side of the upper ends of the two uprights, one end of the sealing plate is hinged to one of the uprights, and the other end of the sealing plate is detachably connected to the other upright. By disassembling the other end of the sealing plate, the sealing plate can be rotated, making it easier for the patient to enter the support frame.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. In this invention, the patient enters the support frame, supports their body by holding onto the frame, and moves the frame using multiple casters to assist in walking exercises, thereby accelerating the recovery speed of the patient's lower limbs. When the patient's body shifts and causes the support frame to tilt, the tilt sensor detects the tilt and controls the extension mechanism to extend to both sides in the width direction of the support frame, widening the height of the support frame chassis. This provides support when the support frame tilts, effectively preventing the patient from falling and getting injured when the support frame tilts. Furthermore, the extension mechanism effectively reduces the width of the support frame, minimizing the impact on pedestrians when the patient exercises in narrow areas such as corridors.

[0022] 2. When the tilt sensor detects that the support frame is tilting, the support column moves outward, causing the rack fixedly connected to it to move. The rack drives the threaded shaft to rotate through gears, causing the threaded shaft to move upward relative to the support frame, thereby reducing the height of the support frame and lowering its center of gravity, effectively preventing the support frame from tipping over. Furthermore, as the lower support frame descends, the lower end of the support frame pushes the upper end of the brake plate downward, causing the brake plate to abut against the roller below. This friction between the brake plate and the roller restricts the roller's rotation, stopping the support frame from moving spontaneously when tilted, thus effectively preventing the support frame from moving spontaneously while tilted and potentially knocking over the patient.

Detailed Implementation

[0030] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0031] In this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] See Figures 1-5 The present invention provides an embodiment of a walking assistance exercise device, comprising: a support frame 1, casters 2, an extension mechanism 3, and an angle sensor; the support frame 1 is equipped with a plurality of casters 2; the extension mechanism 3 is mounted on the support frame 1 and can extend toward opposite sides of the support frame 1 to widen the width of the chassis of the support frame 1; the angle sensor can sense the angle of inclination of the support frame 1 to control the extension mechanism 3 to extend.

[0034] In practice, the patient enters the support frame 1, supports their body by holding onto the frame, and moves the frame using multiple casters 2 to assist walking exercises, thereby accelerating the recovery speed of the patient's lower limbs. When the patient's body shifts and causes the support frame 1 to tilt, the tilt sensor detects the tilt and controls the extension mechanism 3 to extend to both sides in the width direction of the support frame 1, widening the height of the support frame 1's chassis. This provides support when the support frame 1 tilts, effectively preventing the patient from falling and getting injured when the support frame 1 tilts. Furthermore, the extension mechanism 3 effectively reduces the width of the support frame 1, minimizing the impact on pedestrians when the patient exercises in narrow areas such as corridors.

[0035] See Figures 1-4In other embodiments, the extension mechanism 3 includes a lead screw 31, a nut seat 32, a support column 33, and a motor 34. The lead screw 31 is rotatably mounted on the support frame 1, and nut seats 32 are respectively installed at both ends of the lead screw 31, with the threads of the two nut seats 32 having opposite directions. The support column 33 corresponds one-to-one with the nut seats 32, and the support column 33 is slidably mounted on the support frame 1 and fixedly connected to the nut seats 32. The motor 34 can drive the lead screw 31 to rotate, and the tilt sensor can control the operation of the motor 34. Further, the tilt sensor is a tilt sensor; the tilt sensor senses the angle of inclination of the support frame 1.

[0036] In practice, after the tilt sensor detects that the support frame 1 has tilted, it controls the motor 34 to operate. The motor 34 drives the lead screw 31 to rotate, and the lead screw 31 drives the two nut seats 32 to slide in opposite directions. The nut seats 32 drive the support column 33 to slide in opposite directions, thereby extending to both sides in the width direction of the support frame 1 and effectively preventing the support frame 1 from tipping over.

[0037] See Figures 1-5 In other embodiments, two extension mechanisms 3 are respectively provided along the length of the support frame 1; the universal wheels 2 correspond one-to-one with the support columns 33, and the universal wheels 2 include a rack 21, a threaded shaft 22, a gear 23, a tripod 24, a roller 25, and a brake plate 26; the rack 21 is arranged along the sliding direction of the support column 33 and is fixedly connected to the support column 33; the threaded shaft 22 is arranged vertically and threadedly connected to the support frame 1; the gear 23 is coaxially fixed with the threaded shaft 22, and the gear 23 meshes with the rack 21; the tripod 24 is rotatably mounted on the lower end of the threaded shaft 22; the roller 25 is mounted on the tripod 24; the brake plate 26 is located above the roller 25 and below the support frame 1, and the lower end of the brake plate 26 is hinged to the tripod 24; furthermore, a brake pad 28 is installed on the side of the brake plate 26 near the roller 25; the brake pad 28 increases the friction with the wheel, thereby making it easier to restrict the rotation of the roller 25.

[0038] In practice, after the tilt sensor detects that the support frame 1 is tilted, the support column 33 moves outward, causing the support column 33 to drive the rack 21 fixedly connected to it to move. The rack 21 drives the threaded shaft 22 to rotate through the gear 23, causing the threaded shaft 22 to move upward relative to the support frame 1, thereby reducing the height of the support frame 1 and lowering its center of gravity, thus effectively preventing the support frame 1 from tipping over. When the lower support frame 1 descends, the lower end of the support frame 1 pushes the upper end of the brake plate 26 to rotate downward, causing the brake plate 26 to abut against the roller 25 below. This uses the friction between the brake plate 26 and the roller 25 to limit the rotation of the roller 25, so that the support frame 1 can stop moving when it tilts, thus effectively preventing the support frame 1 from moving spontaneously while tilting and knocking over the patient.

[0039] See Figures 1-5 In other embodiments, the caster wheel 2 also includes a spring 27, which is mounted on the triangular plate and applies a spring force to the brake plate 26 away from the roller 25. Specifically, by applying a spring force to the brake plate 26 away from the roller 25 through the spring 27, a certain gap is maintained between the brake plate 26 and the roller 25 when the patient is exercising, reducing the contact time with the roller 25 and improving the service life of the brake plate 26.

[0040] See Figures 1-4 In other embodiments, a bumper block 35 is installed at the end of the support column 33 away from the lead screw 31. In specific implementation, the bumper block 35 can be an airbag, which can effectively prevent the support column 33 from hitting pedestrians when it extends outward.

[0041] See Figures 1-4 In other embodiments, a counterweight 36 is installed at the end of the support column 33 away from the lead screw 31. The counterweight 36 can increase the gravity of the support frame 1, thereby increasing the intensity of the patient's walking assistance exercise. Furthermore, by setting the counterweight 36 at both ends, if the support frame 1 tilts, the counterweight 36 at the other end applies a downward gravity to further prevent the support frame 1 from tipping over.

[0042] See Figure 1 In another embodiment, the support frame 1 includes uprights 11, connecting columns 12, support plates 13, and sealing plates 14; the two uprights 11 are arranged parallel to each other, and the two sides of the lower ends of the two uprights 11 are fixedly connected by the connecting columns 12; one side of the upper end of the two uprights 11 is fixedly connected by the support plates 13; the sealing plate 14 is located on the other side of the upper end of the two uprights 11, one end of the sealing plate 14 is hinged to one of the uprights 11, and the other end of the sealing plate 14 is detachably connected to the other upright; in specific implementation, by disassembling the other end of the sealing plate 14, the sealing plate 14 can be rotated, making it easier for the patient to enter the support frame 1.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
