Description

Technical Field

[0001] The present invention belongs to the technical field of elderly walking assistance, and particularly relates to an intelligent walking assistance device. Background Art

[0002] According to international regulations, anyone over the age of 65 can be identified as an elderly person. As they age, their physical functions continue to deteriorate. Some elderly people do not have enough leg strength when walking, so they need to use assisted walking devices to allow people with inflexible legs and feet or even those who have lost the ability to walk to take care of themselves and go out for a walk like normal people. Most elderly people like to go to the woods to cool off. Although existing walkers can easily take the elderly to the woods, they cannot provide a resting place for the elderly when they need to rest. They need to step on the brakes when resting, which is more inconvenient for elderly people with limited mobility. Sometimes they slip or forget to walk, which may cause accidents and frighten them. If the elderly fall asleep, their bodies will be out of control, which may easily cause them to fall.

[0003] In order to solve the above problems, this application proposes an intelligent walking aid device. Summary of the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1-10 As shown;

[0038] An intelligent walking aid device comprises an electric walking aid body 1 and an armrest 11 mounted on the surface of the electric walking aid body 1.

[0039] In this embodiment: Although the existing walker can easily bring the elderly to the woods, it cannot provide a resting place for the elderly when they need to rest. They need to step on the brakes when resting, which is inconvenient for the elderly with limited mobility. Sometimes they slip or forget to walk and have accidents, which may frighten them. Moreover, if the elderly fall asleep, their bodies will be out of control, which may easily cause them to fall. In view of this, in order to solve this technical problem, a fixing component 2, a protective component 3 and a lifting component 4 are added to this application document.

[0040] In combination with the above content, in order to facilitate the fixation of the walking aid device when the elderly are resting and prevent the walker from being displaced, it also includes a fixing component 2 installed in a cavity opened inside the electric walker body 1, and the fixing component 2 includes a bidirectional screw rod 201, a manual rotating wheel 202, a screw rod 205, a screw block 206, an L-shaped clamping plate 207 and a screw block 212. The bidirectional screw rod 201 is rotatably connected in the cavity opened inside the electric walker body 1. One end of the bidirectional screw rod 201 passes through the electric walker body 1 and extends to one side of the electric walker body 1 and is connected to the manual rotating wheel 202 provided on one side of the electric walker body 1. The outer surface of the bidirectional screw rod 201 is threadedly connected to two screw blocks 212, and the same side surface of the two screw blocks 212 is rotatably connected to the screw rod 205. The outer surfaces of the two screws 205 are threadedly connected to the screw blocks 206, and the adjacent sides of the two screw blocks 206 are fixed with L-shaped clamping plates 207.

[0041] In this embodiment, when an elderly person moves to a forest to enjoy the cool air by using the electric walker body 1, the elderly person turns the electric walker body 1 with its back to the fixed tree and controls the electric walker body 1 to automatically move backward so that the two L-shaped clamping plates 207 are on both sides of the tree to be fixed. At this time, the elderly person standing on the left side of the electric walker body 1 can manually rotate the manual wheel 202 to rotate the bidirectional screw rod 201, and the two screw blocks 212 threadedly connected to the outer surface of the bidirectional screw rod 201 drive the two screw rods 205 to cause the two L-shaped clamping plates 207 threadedly connected to the surface of the screw rod 205 to move toward the surface of the tree until the tree is clamped between the two L-shaped clamping plates 207. In this way, the electric walker body 1 can be clamped to the outside of the tree by the L-shaped clamping plates 207, thereby limiting the position of the electric walker body 1 to prevent it from moving during the cool air, and preventing the elderly person from being frightened by sudden changes.

[0042] In an optional embodiment, a second gear 203 is mounted on the outer surface of the same end of the two screw rods 205 . The two second gears 203 are engaged with a second gear plate 204 . The second gear plate 204 is mounted in a cavity provided inside the electric walker body 1 .

[0043] In this embodiment, based on this arrangement, when the bidirectional screw rod 201 rotates and the two screw blocks 212 threadedly connected to the outer surface of the bidirectional screw rod 201 drive the two screw rods 205 to cause the two L-shaped clamping plates 207 threadedly connected to the surface of the screw rod 205 to move toward the surface close to the tree, the gear 203 on the outer surface of one end of the screw rod 205 connected to one side of the screw block 212 can drive the screw rod 205 to rotate under the action of the gear plate 204, so that the L-shaped clamping plate 207 threadedly connected to the outer side of the screw rod 205 moves toward the side close to the tree. At the same time, it can move on the outer side of the screw rod 205 toward the side close to the screw block 212, which is beneficial for the L-shaped clamping plate 207 to reduce the virtual space between the electric walker body 1 and the tree when clamping the tree, thereby avoiding displacement between the electric walker body 1 and the tree after the electric walker body 1 is fixed to the tree.

[0044] In an optional embodiment: a same guide rod 211 is slidably connected in the blind grooves opened on the surfaces of the two screw blocks 212, the guide rod 211 is fixed in the cavity opened inside the electric walker body 1, and a guide slide rod 213 is slidably connected in the through hole opened on the surface of the screw block 206, and one end of the guide slide rod 213 is connected to the screw block 212.

[0045] In this embodiment: Based on this arrangement, when the two screw blocks 212 move on the surface of the bidirectional screw rod 201, the screw blocks 212 can be limited to prevent the screw blocks 212 from deflecting during the movement. At the same time, when the screw rod 205 is rotated, the L-shaped clamping plate 207 threadedly connected to the outside of the screw rod 205 moves toward the side close to the tree. At the same time, when it moves toward the side close to the screw block 212, the guide slide bar 213 can limit the screw block 206 to ensure the smooth movement of the screw block 206 and prevent the screw block 206 from causing the L-shaped clamping plate 207 to deflect.

[0046] In an optional embodiment: an arc-shaped abutment plate 21 is provided between the two L-shaped clamping plates 207 and on one side of the electric walker body 1, and a transmission guide rod 22 is integrally formed on the surface of one side of the arc-shaped abutment plate 21. The transmission guide rod 22 extends to the outer surface of one end of the cavity opened inside the electric walker body 1 and is symmetrically installed with an L-shaped connecting plate 23. A tooth plate 1 24 is installed on the surface of the L-shaped connecting plate 23, and a transmission rod 25 is rotatably connected to the cavity opened inside the electric walker body 1, a gear 1 26 is installed on the outer surface of the transmission rod 25, and the gear 1 26 is meshedly connected to the surface of the tooth plate 1 24, a pulley 1 27 is installed on the outer surface of the transmission rod 25, and a pulley 2 29 is installed on the outer surface of the bidirectional screw rod 201, and the pulley 1 27 and the pulley 2 29 are connected by a V-belt 28.

[0047] In this embodiment, based on this arrangement, when the electric walker body 1 is controlled to automatically reverse and approach a tree, one side of the arc-shaped abutment plate 21 can contact the tree, and the arc-shaped abutment plate 21 is subjected to force, thereby driving the transmission guide rod 22 to move into the cavity provided inside the electric walker body 1. At this time, the transmission guide rod 22 can drive the L-shaped connecting plates 23 installed on both sides thereof to move to one side, and under the coordinated transmission of the tooth plate 1 24 and the gear 1 26 on the surface of the L-shaped connecting plate 23, the transmission rod 25 itself can rotate in the cavity provided inside the electric walker body 1, and the bidirectional screw rod 201 itself can be driven to rotate by the V-belt 28 connected between the pulley 1 27 and the pulley 2 29. (In conjunction with the contents of the above embodiment), the L-shaped clamping plate 207 can be caused to clamp the tree, conveniently utilizing the kinetic energy of the electric walker body 1 to achieve fixed position between it and the tree, and reducing the labor intensity of the elderly who manually rotate the manual wheel 202 to achieve fixed position.

[0048] In an optional embodiment: the two L-shaped connecting plates 23 are integrally formed with guide posts 208 on their surfaces facing away from each other, and a guide groove 209 adapted to the guide post 208 is provided in a cavity provided inside the electric walker body 1, and the L-shaped connecting plates 23 are slidably connected in the cavity provided inside the electric walker body 1 through the guide post 208 and the guide groove 209.

[0049] In this embodiment: Based on this arrangement, in order to facilitate contact with the tree on one side of the arc-shaped abutment plate 21 and to make the arc-shaped abutment plate 21 subjected to force, thereby driving the transmission guide rod 22 to move into the cavity set inside the electric walker body 1, the transmission guide rod 22 can be guided by the guide columns 208 set on both sides of the L-shaped connecting plate 23 and the guide grooves 209 opened in the cavity set inside the electric walker body 1, so that the transmission guide rod 22 together with the two L-shaped connecting plates 23 can move smoothly in the cavity set inside the electric walker body 1.

[0050] In an optional embodiment: a fixed block 214 is installed in a cavity provided inside the electric walker body 1, a telescopic rod 215 is installed on one side surface of the fixed block 214, the other end of the telescopic rod 215 is installed in a groove opened on the surface of the transmission guide rod 22, and a spring 216 is sleeved on the outer surface of the telescopic rod 215, one end of the spring 216 abuts against the fixed block 214, and the other end of the spring 216 abuts against the groove opened on the surface of the transmission guide rod 22.

[0051] In this embodiment: based on this arrangement, when the arc-shaped abutment plate 21 is subjected to force, thereby driving the transmission guide rod 22 to move into the cavity provided inside the electric walker body 1, the spring 1 216 on the outside of the telescopic rod 215 can be compressed. When the fixation is released, the manual wheel 202 can be manually rotated to make the two L-shaped clamps 207 pre-detach from the surface of the tree. After detaching to a certain extent, the transmission guide rod 22 is pushed out of the cavity provided inside the electric walker body 1 under the weight of the spring 1 216 itself, so that the tooth plate 1 drives the gear 1 26 to reverse, and drives the bidirectional screw rod 201 to reverse with the cooperation of the pulley group, so that the L-shaped clamp 207 can be completely detached from the tree surface. In this operation, with the help of the braking function of the electric walker body 1 itself, the electric walker body 1 can become smooth in the process of detaching from the tree.

[0052] In an optional embodiment: a telescopic protective shell 217 is slidably connected to one side of the electric walker body 1 and located on the outside of the two L-shaped clamps 207, and a T-shaped limiting guide rod 219 is slidably connected in a through hole opened on the surface of one side of the telescopic protective shell 217. The outer surface of the limiting guide rod 219 is sleeved with a spring 221, one end of the spring 221 abuts against one side of the electric walker body 1, and the other end of the spring 221 abuts against the telescopic protective shell 217, and the surface of the telescopic protective shell 217 is opened with an avoidance groove 218 adapted to the manual wheel 202.

[0053] In this embodiment: Based on this setting, the components located in the telescopic protective shell 217 are protected by the provided telescopic protective shell 217. At the same time, when the electric walker body 1 is controlled to automatically reverse and approach one side of a tree, the arc-shaped groove on the surface of the telescopic protective shell 217 can pre-contact the tree, ensuring that during the reverse process, the two L-shaped clamping plates 207 can be located on both sides of the tree, and the arc-shaped abutment plate 21 can contact the surface of the tree and play a guiding role. At the same time, when the telescopic protective shell 217 slides toward one side of the electric walker body 1, the provided avoidance groove 218 can avoid the manual wheel 202 to prevent the structure from getting stuck. At the same time, the provided limit guide rod 219 can guide the telescopic protective shell 217 to prevent the telescopic protective shell 217 from getting stuck when sliding, and compress the spring 221. When the fixation is released, the spring 221 plays the role of resetting the telescopic protective shell 217.

[0054] In combination with the above content, in order to conveniently provide a resting position for the elderly and improve their comfort during the rest process, it also includes a lifting assembly 4 installed on one side of the electric walker body 1. The lifting assembly 4 includes a hinged ear 41, a support plate 42, a guide slide 43, a U-shaped frame 44, a roller 45 and a magnet 47. The hinged ear 41 is symmetrically installed on the surface of one side of the electric walker body 1. The two hinged ears 41 are symmetrically connected to the same support plate 42 through a rotating shaft. A guide slide 43 is installed on the surface of one side of the support plate 42. A U-shaped frame 44 is installed at one end of the transmission guide rod 22. A roller 45 is rotatably connected to the U-shaped frame 44 through a rotating shaft. The roller 45 is slidably connected to the guide slide 43, and a storage groove 46 adapted to the guide slide 43 is opened on one side of the electric walker body 1, and a magnet 47 is symmetrically installed on this side of the electric walker body 1.

[0055] In this embodiment: when the arc-shaped abutment plate 21 at one end of the transmission guide rod 22 is subjected to the reaction force from the tree, one end of the transmission guide rod 22 can slide toward the electric walker body 1. At this time, the roller 45 in the U-shaped frame 44 installed at one end of the transmission guide rod 22 can move toward one side of the support plate 42, so that the roller 45 is pressed into the guide rail 43, prompting one end of the transmission guide rod 22 to support the support plate 42 through the roller 45, and to enable the support plate 42 to deflect around the two hinged ears 41, so that the support plate 42 can support the legs of the elderly, conveniently providing a resting position for the elderly and improving their comfort during the rest process.

[0056] It should be noted that the storage groove 46 is provided to facilitate the storage and hiding of the guide rail 43 in the initial position, and the magnet 47 is provided to attract the support plate 42 in the initial state to prevent the position of the support plate 42 from changing during the movement of the electric walker body 1.

[0057] In combination with the above content, in order to prevent the elderly from falling down due to the body being out of control after falling asleep, a protective component 3 is also included which is installed on the surface of the electric walker body 1. The protective component 3 includes a hinged rod 31, a movable strip 32, a tooth plate 33, a gear 34, a transmission shaft 36, a gear 4 301, an arcuate retaining ring 302 and an arcuate tooth plate 303. The outer surface of one end of the transmission guide rod 22 is symmetrically hinged with a hinged rod 31, and the other ends of the two hinged rods 31 are hinged with a movable strip 32. A tooth plate 33 is installed on one side surface of the movable strip 32. A transmission shaft 36 is rotatably connected to a cavity provided inside the electric walker body 1. A gear three 34 is installed on the outer surface of one end of the transmission shaft 36. The gear three 34 is meshedly connected to one side of the gear plate three 33. The other end of the transmission shaft 36 extends into the handrail 11 provided on the surface of the electric walker body 1 and is connected to the gear four 301 provided in the handrail 11. The outer surface of the gear four 301 is meshedly connected to the arc-shaped tooth plate 303, and the outer side of the arc-shaped tooth plate 303 is integrally formed with an arc-shaped retaining ring 302, which is slidably connected to the arc groove opened on the surface of the handrail 11.

[0058] In this embodiment, when the arc-shaped abutment plate 21 at one end of the transmission guide rod 22 is subjected to the reaction force from the tree, one end of the transmission guide rod 22 can slide toward the electric walker body 1, and at the same time, it can drive one end of the two hinged rods 31 to move together, prompting one end of the two hinged rods 31 to apply pressure to the moving strips 32, and causing the two moving strips 32 to slide toward the two sides of the electric walker body 1. At this time, the tooth plate three 33 installed on one side of the moving strips 32 can rotate the transmission shaft 36 under the action of the gear three 34, and cause the gear four 301 installed in the armrest 11 and located at one end of the transmission shaft 36 to rotate, prompting the arc-shaped tooth plate 303 meshing with the surface of the gear four 301 to drive the arc-shaped retaining ring 302 to slide out of the armrest 11, so that one end of the two arc-shaped retaining rings 302 is closed, and the elderly sitting on the electric walker body 1 is embraced, so as to prevent the elderly from falling out of control after falling asleep.
