Description

Technical Field

[0001] The present invention relates to the technical field of walking devices, and more specifically, to an intelligent walking aid for Parkinson's disease patients. Background Art

[0002] Parkinson's disease is a chronic neurological disease that primarily affects the patient's motor ability, leading to symptoms such as muscle stiffness, tremor, balance disorders and unstable gait. As the disease progresses, patients often have difficulty walking, especially in gait initiation, turning and maintaining balance, which not only seriously affects the patient's quality of life, but also increases the risk of falling, further limiting their ability to live independently.

[0003] Currently, there are a variety of walking assist devices on the market to help people with limited mobility improve walking stability and safety. However, these devices often have shortcomings in response to the special needs of Parkinson's patients. The brake system currently used in the walkers used by Parkinson's patients is opposite to the conventional brake system. The conventional method is to press the brake handle when braking, while Parkinson's patients use it by pressing the brake handle while walking, so that when the hand shakes, the walker can stop and provide support to the patient.

[0004] However, when using such a walker, patients need to continue to hold the handle tightly to maintain the normal walking state of the device. Long-term hand force will not only cause hand fatigue in patients, but may also aggravate the symptoms of hand tremors, thereby further affecting the stability and safety of walking.

[0005] In order to solve the above problems, an intelligent walking aid for Parkinson's patients is proposed. Summary of the invention

[0040] For examples, see Figure 1 - Figure 7 , an intelligent walking aid for Parkinson's disease patients, comprising a frame mechanism 1, an electromagnetic brake wheel 2 arranged at the bottom of the frame mechanism 1, and an intelligent handle 3 arranged on the frame mechanism 1;

[0041] The smart grip 3 includes a grip rod 301 disposed on the frame mechanism 1, a hand shake trigger component 4 movably plugged into the top of the grip rod 301, and a feedback control component 5 disposed inside the grip rod 301;

[0042] The feedback control component 5 and the electromagnetic brake wheel 2 are electrically connected via a wire;

[0043] A first strip groove 302 is formed at the top of the grip 301, and the hand-shake trigger component 4 is movably inserted into the first strip groove 302. One end of the hand-shake trigger component 4 that passes through the first strip groove 302 and enters the inner cavity of the grip 301 contacts the feedback control component 5, and the hand-shake trigger component 4 acts on the feedback control component 5 in different contact forms to form different feedback signals.

[0044] The feedback control assembly 5 includes a main control board 501 disposed in the inner cavity of the grip 301, a first feedback member 502 disposed on the main control board 501, and a second feedback member 6 disposed on the inner wall of the inner cavity of the grip 301 and electrically connected to the main control board 501;

[0045] An elastic member 7 is arranged between the first feedback member 502 and the hand-shake trigger component 4 .

[0046] The grip 301 and the frame mechanism 1 are integrally formed, and the hand-shake trigger component 4 is located at the top of the grip 301. The hand-shake trigger component 4 can be plugged up and down in the first strip groove 302, and can also move back and forth along the length direction of the first strip groove 302. The first feedback component 502 is a pressure sensor, and the pressure sensor is a sheet-type pressure sensor. The elastic component 7 is arranged at the top of the sheet-type pressure sensor, and the top of the elastic component 7 resists one end of the hand-shake trigger component 4 plugged into the inner cavity of the grip 301, so that when the grip 301 is pressed down, it can compress the elastic component 7, thereby passing the elastic component The reaction force of 7 acts on the chip pressure sensor, and then transmits the pressure value to the main control board 501, which analyzes whether a start command is issued to the electromagnetic brake wheel 2. Two second feedback components 6 are provided, which are respectively arranged on both sides of one end of the hand-shake trigger component 4 inserted into the inner cavity of the handle 301, so that when the hand-shake trigger component 4 moves back and forth along the length direction of the first strip groove 302, it can hit and touch the second feedback component 6, thereby generating an electrical signal, and then combined with the pressure value of the first feedback component 502, it is analyzed whether a brake stop command is issued to the electromagnetic brake wheel 2.

[0047] Specifically, when a Parkinson's patient is walking, his hands may suddenly shake, causing his hands to separate from the grip 301, and the walker may slip. Currently, there are walkers on the market that can automatically stop the walker when the hands shake and separate from the grip 301. The main method is to reverse the brake system. When the walker needs to walk normally, the patient holds the brake handle tightly, and when the hands shake, the elasticity automatically resets to stop the walker. Such equipment on the market solves this technical problem casually, but it also brings another problem, that is, the patient needs to hold the brake handle tightly when walking, which will cause the patient's hands to continue to exert force, which will make the patient tired over time, and it will be inconvenient for the patient to support the walker with his hands.

[0048] In this regard, the present invention sets the hand tremor trigger component 4 at the top of the grip bar 301. When the patient uses the walker and holds the grip bar 301 tightly, he only needs to use the patient's body to support the downward pressure of the walker to push the hand tremor trigger component 4 downward, thereby compressing the elastic member 7. The elastic member 7 generates a reaction force through compression and acts on the first feedback member 502, so that the first feedback member 502 on the main control board 501 generates pressure. When the hand tremor trigger component 4 is pressed down to fit the top of the grip bar 301, the pressure value reaches the set value, and the first feedback member 502 transmits the pressure value to the main control board 501, and then the brake command of the electromagnetic brake wheel 2 is released through the main control board 501, so that the electromagnetic brake wheel 2 can be pushed normally.

[0049] When a Parkinson's patient suddenly experiences severe hand tremors during walking and his hand is separated from the grip bar 301, the elastic member 7 lifts up the hand tremor trigger component 4 as the hand is separated from the grip bar 301, so that the hand tremor trigger component 4 and the patient's hand always keep in contact. At the same time, as the elastic member 7 is lifted up and stretched, its reaction force is reduced, so that the pressure value acting on the first feedback member 502 is reduced, and its pressure value change is transmitted to the main control board 501. The hand tremor trigger component 4 that is lifted up and in contact with the patient's hand is moved in the first strip groove by the patient's hand tremor. 302 moves back and forth, so that the hand tremor trigger component 4 hits the second feedback component 6. After the second feedback component 6 is hit, an electrical signal is generated and transmitted to the main control board 501. At this time, the pressure value feedback by the first feedback component 502 decreases and the electrical signal feedback by the second feedback component 6, and then it is judged that the Parkinson's patient is in a state of severe hand tremor. Therefore, the main control board 501 sends a brake stop command to the electromagnetic brake wheel 2, so that the walker stops, which can provide stable support for the patient and prevent the patient from falling.

[0050] A manual switch 8 is provided on the frame mechanism 1 near the handle 301 , and the manual switch 8 and the main control board 501 are electrically connected via a wire.

[0051] A manual switch 8 is added so that the unlocking signal of the electromagnetic brake wheel 2 is combined, thereby preventing the patient from falling due to subsequent support and unlocking of the electromagnetic brake wheel 2.

[0052] Among them, as mentioned above, when the hand-shaking trigger component 4 is pressed down to fit the top of the grip rod 301, the pressure value reaches the set value, and then the braking command of the electromagnetic brake wheel 2 is released through the main control board 501, so that the electromagnetic brake wheel 2 can be pushed normally. However, if the electromagnetic brake wheel 2 is unlocked only by pressing down the hand-shaking trigger component 4, then after the patient's hand shakes violently and breaks away from the grip rod 301, the walking device brakes the electromagnetic brake wheel 2 through the first feedback component 502 and the second feedback component 6. The purpose of the braking is to enable the walking device to provide subsequent support to the patient. Therefore, after the patient's hand shakes violently and breaks away from the grip rod 301, if the subsequent support acts on the frame mechanism 1, stable support can be provided.

[0053] However, if subsequent support acts on the smart handle 3, the hand shake trigger component 4 will be pushed down again, thereby triggering the unlocking of the electromagnetic brake wheel 2 again. Therefore, the present invention adds a manual switch 8 to the frame mechanism 1, and the manual switch 8 and the hand shake trigger component 4 are pressed down to cooperate with each other, thereby realizing the unlocking of the electromagnetic brake wheel 2.

[0054] Specifically, in the initial state, the electromagnetic brake wheel 2 is in a locked state. When in use, the patient grips the grip 301 so that the hand tremor trigger component 4 is pressed down, causing the pressure value on the first feedback component 502 to change. At this time, the manual switch 8 is pressed again, and the pressure value change on the first feedback component 502 and the electrical signal generated by the manual switch 8 are combined into an unlocking signal of the electromagnetic brake wheel 2, and then the main control board 501 unlocks the electromagnetic brake wheel 2, thereby avoiding the patient's hand tremors during use, which causes the electromagnetic brake wheel 2 to stop. The subsequent support of the patient causes the pressure value change caused by the downward pressure of the hand tremor trigger component 4, thereby causing the main control board 501 to unlock the electromagnetic brake wheel 2, causing the patient to fall.

[0055] The hand-trembling trigger assembly 4 includes a connecting rod 401 movably inserted into the first strip groove 302, a contact ball 402 arranged at one end of the connecting rod 401 located in the inner cavity of the grip rod 301, and a pressing block 403 arranged at one end of the connecting rod 401 away from the contact ball 402;

[0056] The elastic member 7 is a return spring, and the abutment ball 402 abuts against the top of the return spring.

[0057] In the initial state, under the push of the return spring, the resistance ball 402 is pushed through the connecting rod 401 so that the pressing block 403 is located above the grip rod 301, and there is a certain downward pressure distance between the pressing block 403 and the grip rod 301. When in use, the patient holds the grip rod 301 tightly, and the gripping gesture pushes the pressing block 403 downward, thereby causing the connecting rod 401 to move downward, and then the resistance ball 402 pushes the compression return spring, and the rebound force of the return spring acts on the first feedback member 502, thereby generating a pressure value.

[0058] A shaft rod 303 is disposed below the first strip groove 302, and connecting blocks 304 are disposed at both ends of the shaft rod 303. One end of the connecting block 304 away from the shaft rod 303 is welded to the bottom of both ends of the first strip groove 302 in the width direction.

[0059] The connecting rod 401 is provided with a movable groove 404 along its axial direction, and the shaft rod 303 and the movable groove 404 are movably matched.

[0060] When the hand tremor trigger component 4 is pressed down to the bottom, the shaft 303 is located at the top of the movable groove 404, and the connecting rod 401, the resistance ball 402, the elastic member 7 and the first feedback member 502 are coaxial, thereby ensuring that the hand tremor trigger component 4 is located in the middle of the two second feedback members 6 after being pressed down. Then, when the patient has severe hand tremor symptoms, the reset spring pushes the resistance ball 402 to move upward, so that the axis of the shaft 303 moves downward in the movable groove 404. Through the principle of leverage, the patient's hand shaking drives the connecting rod 401 to rotate more easily around the shaft 303 as the axis, so that the resistance ball 402 hits both sides, thereby generating an electrical signal.

[0061] The second feedback member 6 includes a micro switch 601 fixedly mounted on the inner wall of the inner cavity of the grip 301 , and a driving plate 602 movably plugged into the micro switch 601 .

[0062] The resistance ball 402 generates an electrical signal by hitting the micro switch 601, but the trigger point of the micro switch 601 is a fixed point. Therefore, when the patient's hand shakes, the resistance ball 402 is not easy to hit the trigger point of the micro switch 601. In order to solve this problem, a corresponding driving plate 602 is provided on the surface where the trigger point of the micro switch 601 is located. It should be noted that in the initial state and the pressed state of the hand shaking trigger component 4, the resistance ball 402 is within the range of hitting the driving plate 602. Therefore, no matter to what extent the patient's hand shakes and releases the grip 301, the resistance ball 402 can hit the driving plate 602 by rotating, and then act on the switch of the micro switch 601 through the driving plate 602 to generate an electrical signal.

[0063] The first feedback member 502 is provided with a pressing threshold and a reset threshold, and when the pressure value of the elastic member 7 acting on the first feedback member 502 is the reset threshold, the main control board 501 issues a locking command.

[0064] According to the elastic force of the elastic member 7, a depression threshold range is set for the hand-trembling trigger component 4 to be pressed to the bottom, such as ab. The pressure value of the first feedback member 502 is within this range, indicating that the hand-trembling trigger component 4 is pressed to the bottom and the hand is in a clenched state. Then a reset threshold is set after the hand-trembling trigger component 4 is fully reset, such as cd. The pressure value of the first feedback member 502 is within this range, indicating that the hand-trembling trigger component 4 is fully reset and the hand is away from the grip 301.

[0065] Specifically, if the patient shakes and releases the grip 301, and the hand shaking drives the hand shaking trigger component 4 to rotate with the shaft 303 without hitting the triggering second feedback component 6, then after the hand shaking trigger component 4 is completely released, only the change in the pressure value of the first feedback component 502 can trigger the main control board 501 to issue a braking command to the electromagnetic brake wheel 2. Therefore, when the patient's hand shakes and leaves the grip 301 and does not drive the resistance ball 402 to hit the second feedback component 6, the braking command to the electromagnetic brake wheel 2 can be issued solely through the pressure value of the first feedback component 502 being within the reset threshold cd threshold range.

[0066] It should also be noted that, through the decrease in the pressure value feedback from the first feedback component 502 and the electrical signal feedback from the second feedback component 6, it is judged that the Parkinson's patient is in a state of severe hand tremor at this time, and then when the main control board 501 issues a brake command, it is necessary for the pressure value on the first feedback component 502 to decrease and change out of the downward pressure threshold range. If the pressure value change on the first feedback component 502 is within the downward pressure threshold range, the main control board 501 will not issue a brake command.

[0067] A coaxial through hole 503 is provided at the center of the first feedback member 502 and the main control board 501;

[0068] A pull rope 9 is disposed at the bottom of the resistance ball 402 , and one end of the pull rope 9 away from the resistance ball 402 passes through the through hole 503 and the inner wall of the grip rod 301 .

[0069] By setting the pull rope 9, when the return spring pushes the resistance ball 402 to move up to the highest point, the pull rope 9 is straightened, so that the resistance ball 402, the connecting rod 401 and the return spring are coaxial, so that the hand shaking trigger component 4 is pushed by the return spring to maintain a vertical state, and the pressing block 403 will not be in a tilted state, which will cause it to easily hit the second feedback component 6 when it is pressed down subsequently, thereby reducing the service life of the second feedback component 6.

[0070] The bottom of the pressing block 403 is provided with an anti-slip rubber 405. Through the setting of the anti-slip rubber 405, when the hand is clenched, the rotation of the hand is reduced, thereby driving the rotation of the hand shaking trigger component 4, thereby causing the resistance ball 402 to hit the second feedback component 6, causing unnecessary consumption, and reducing the service life of the micro switch 601.

[0071] The frame mechanism 1 includes a support frame 101 for mounting the electromagnetic brake wheel 2 , and a transverse plate 102 and a stop bar 103 arranged on the support frame 101 .

[0072] A storage battery is arranged inside the support frame 101 for supplying power to the main control board 501 , the horizontal plate 102 is used to provide a sitting position for the patient, and the baffle bar 103 is used to provide a backrest for the patient to prevent the patient from falling.

[0073] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
