Description

Technical Field

[0001] The present invention relates to the technical field of crutch, in particular to an intelligent anti-fall crutch. Background Art

[0002] A cane is a handheld stick-shaped device used to prevent falls. Current crutches only have a stick-shaped structure, which is not stable enough to support the ground. It is effective in preventing the human body from falling forward, but cannot effectively prevent falling backward or sideways. Falling backward is often more likely to cause serious injuries, especially for the elderly. This problem needs to be solved urgently. Summary of the Invention

[0003] The main problem solved by the present invention is how to enable the crutch to prevent the human body from falling backward and sideways to a certain extent.

[0004] An intelligent anti-fall crutch, characterized in that it includes a stick-shaped structure, a rotating shaft, a spring, a triangular prism, a steel wire rope, and a magnetic structure. The stick-shaped structures are provided with three, and the rotating shafts are provided with three, connected in a triangle and installed at the upper ends of the three stick-shaped structures. Each rotating shaft passes through a stick-shaped structure, and the three stick-shaped structures can rotate around the rotating shaft to achieve merging and opening. The springs are provided with three, installed between the three stick-shaped structures, and the triangular prism is located between the three stick-shaped structures. One end of each spring is connected to the stick-shaped structure, and the other end is connected to one face of the triangular prism. When the three stick-shaped structures are merged, the springs are compressed. There are three steel wire ropes, and one end of each steel wire rope is connected to the stick-shaped structure, and the other end is connected to the triangular prism. When the three stick-shaped structures are combined, the steel wire rope is bent. When the three stick-shaped structures are opened, the steel wire rope is pulled apart, limiting the opening angle of the three stick-shaped structures. The magnetic attraction structure includes a soft magnet and two permanent magnets. The three magnets are respectively installed on the three stick-shaped structures. When the three stick-shaped structures are combined, the soft magnet is located between the two permanent magnets. The soft magnet is attracted to the two permanent magnets. A coil is wound around the soft magnet. The coil forms a loop with the power supply and the switch through a wire. The switch is located at the upper end of the stick-shaped structure. When the switch is pressed, the magnetic direction of the soft magnet changes, repelling the two permanent magnets. At the same time, three springs pop open, and the three stick-shaped structures are separated.

[0005] The beneficial effect is that, in normal times, the soft magnet is attracted to the two permanent magnets, and the three stick-shaped structures are combined to be used as an ordinary crutch; when the human body is standing unsteadily, the switch is pressed, the magnetic direction of the soft magnet changes, and it repels the two permanent magnets, and the three springs quickly spring the three stick-shaped structures apart, and the three stick-shaped structures are separated. The steel wire rope fixes the angle at which the stick-shaped structures are opened, and the upper end of the handheld anti-fall crutch is held so that the three stick-shaped structures are respectively located in the front, back, and sides of the human body. The three stick-shaped structures stably support the ground, keep the human body standing stably, and can prevent the human body from falling forward, backward, and sideways. The anti-fall crutch can be used as an ordinary crutch in normal times, and can also be quickly opened when there is a risk of falling. The three stick-shaped structures can stably support the ground, keep the human body stable, and especially can prevent the human body from falling backward and sideways, and has relatively significant practical value. The soft magnet is located between the two permanent magnets. When the three stick-shaped structures are combined, the soft magnet and the two permanent magnets have opposite magnetic properties. The soft magnet can prevent the two permanent magnets from repelling each other and allow the three magnets to be attracted together, ensuring the stable combination of the three stick-shaped structures. At the same time, after pressing the switch, the soft magnet changes its magnetic properties, and the soft magnet and the two permanent magnets repel each other, and the three stick-shaped structures are opened. In addition, only three magnets are required, resulting in a simple and effective structure. The three rotating shafts are connected in a triangle, which not only enables the three stick-shaped structures to rotate around the rotating shaft to achieve combination and opening, but also allows the three stick-shaped structures to be simply and stably combined.

[0006] It also includes a handle, which is located on the rotating shaft. The handle is connected to the three connections of the three rotating shafts through three pillars. The three connections of the three rotating shafts are the three corners of the triangle. The switch is located on the handle.

[0007] The beneficial effect is that the handle is connected to the three connection points of the three rotating shafts through three pillars, which not only effectively utilizes the triangular structure of the three rotating shafts, but also makes the structure of the handle quite stable, and the handle will not tilt when the three stick-shaped structures are combined and opened, which is convenient for use. At the same time, there is a handle above the stick-shaped structure, and the handle can be held by hand to be used as an ordinary crutch. The switch is located on the handle, which is convenient for pressing the switch in time when you are about to fall.

[0008] There is a hole on the stick-shaped structure, one end of the spring is located in the hole, the cross-section of the hole is elliptical, and the upper and lower widths of the ellipse are greater than the left and right widths; it also includes a connecting rod, the upper end of which is connected to the handle and the lower end of which is connected to the triangular prism, and its main body is located between the three stick-shaped structures.

[0009] The beneficial effect is that there is a hole on the stick-shaped structure, which can accommodate a spring of a longer length, so that the spring has sufficient telescopic distance. The cross-section of the hole is elliptical because when the three stick-shaped structures are opened, the spring and the stick-shaped structure will form a certain angle to prevent the spring from being blocked by the edge of the hole; the connecting rod can fix the position of the triangular prism and maintain the stability of the spring structure.

[0010] The coil is also provided with a reverse power supply module. When the switch is pressed and the three stick-shaped structures are opened, the reverse power supply module is automatically started, so that the magnetism of the soft magnet is reversed, facilitating the merging of the three stick-shaped structures next time.

[0011] The beneficial effect is that the magnetic properties of the soft magnet are reversed, and when they are close to each other, they will generate attraction with the permanent magnet, which is convenient for the next merging of the three stick-shaped structures.

[0012] The spring is located at the upper part of the stick-shaped structure, and the magnetic attraction structure is located at the lower part of the stick-shaped structure.

[0013] The beneficial effect is that, with the rotating shaft as the center, the moment length of the magnetic structure is greater than that of the spring. Even if the attraction force of the magnetic structure is less than that of the spring, the stick-shaped structures can be smoothly merged. Of course, to ensure structural stability during merging, the permanent magnet can be a strong magnet to further enhance the attraction force of the magnet.

[0014] The steel wire rope passes through the interior of the spring, and when the three stick-shaped structures are combined, the steel wire rope is curled up inside the spring.

[0015] The beneficial effect is that the telescopic length of the steel wire rope is limited, and the opening angle of the three stick-shaped structures can be controlled. At the same time, the steel wire rope is located entirely inside the spring, and does not require other installation positions as a whole, and the structure is simple and neat.

[0016] It also includes a GPS positioning module and a text message sending module. The GPS positioning module obtains the positioning information of the crutch. When the switch is pressed, the text message sending module sends the positioning information to the outside world.

[0017] The beneficial effect is that, although pressing the switch can effectively prevent falls, there is still a possibility of an accidental fall. At this time, the synchronous sending of information to the outside world can timely attract the attention of the outside world and further ensure safety. The SMS sending module can be bound to the guardian's mobile phone number. The reason why the SMS is sent to the outside world when the switch is pressed synchronously can avoid being unable to send information after a fall. Of course, if no fall occurs, the outside world can be informed of safety by phone.

[0018] Alternatively, it further includes a GPS positioning module and a text message sending module, wherein the GPS positioning module obtains the positioning information of the crutch, and when the crutch falls, the text message sending module is activated to send the positioning information to the outside world.

[0019] The beneficial effect is that information is sent to the outside world only after a fall, which can avoid causing too much disturbance to the outside world. However, it is also possible that information cannot be sent after a fall, resulting in safety risks. An intelligent anti-fall crutch, characterized in that it includes a stick-shaped structure, a rotating shaft, a spring, a steel wire rope, and a magnetic structure. The stick-shaped structures have three pieces, the rotating shafts have three pieces, connected in a triangle, and installed at the upper ends of the three stick-shaped structures.
