Description

Technical Field

[0001] This invention relates to the technical field of hand exercise devices, and particularly to a hand exercise device for preventing Alzheimer's disease. Background Technology

[0002] With the increasing aging of the population, the incidence of Alzheimer's disease is rising year by year, and the resulting cognitive decline and decreased limb coordination seriously affect patients' quality of life. Studies have shown that the hands, as an area with a dense distribution of nerve endings, can effectively stimulate the cerebral cortex through regular exercise, enhancing neuroplasticity and delaying cognitive decline. Traditional hand rehabilitation devices mostly use simple grip strength training or passive massage modes, which have the following drawbacks:

[0003] Limited Functionality: Existing devices mostly focus on single joint movements or muscle strength training, lacking precise stimulation of acupoints and meridians in the palm, making it difficult to achieve synergistic promotion of nerve reflexes and blood circulation. For example, common spring hand grippers only target finger flexor muscles, failing to cover key acupoints such as the thenar eminence and Laogong point on the palm, and lacking dynamic adjustment mechanisms, easily leading to muscle fatigue or insufficient training.

[0004] Low transmission efficiency: Some mechanical devices rely on motors to directly drive the massage head, resulting in a bulky structure, high energy consumption, and the rigid contact can easily cause local pressure injuries. On the other hand, purely manual instruments (such as massage balls) rely on the user to apply force, making it difficult to ensure the stability of the range and frequency of movement, and are particularly unsuitable for the elderly with declining muscle strength.

[0005] Therefore, there is an urgent need to develop a hand exercise device that integrates efficient transmission, adaptive massage, and safety limiting functions. Through multi-degree-of-freedom mechanical coupling design, it can achieve precise acupoint stimulation and flexible force control within a limited space, thereby improving nerve activation efficiency and training comfort, and meeting the long-term rehabilitation needs of the elderly. Summary of the Invention

[0006] The purpose of this invention is to provide a hand exercise device for preventing Alzheimer's disease, comprising:

[0007] The housing and its sliding drive slider, the drive slider extending to the outside of the housing on both sides, are characterized in that a pivotally mounted massage execution plate is disposed on the side wall of the housing. The execution plate is kinematically coupled to the drive slider through a planar linkage transmission mechanism. A massage module is fixedly mounted on the working surface of the execution plate, and its spatial arrangement and positioning are set in the corresponding area of ​​the palm. The planar linkage transmission mechanism includes: a drive shaft, a linear gear rail, a reduction gear set, a spatial reversing gear pair, and a driven transmission rod. The drive shaft is horizontally mounted in the inner cavity of the housing using a slewing bearing method. The reduction gear set is integrated in the middle of the shaft and meshes with the linear gear rail fixed to the drive slider. The drive shaft realizes power steering transmission through a bevel gear pair. The driven transmission rod has its power input end rigidly connected to the bevel gear pair, and its power output end forms a rotary motion with the massage execution plate.

[0008] Preferably, a driving mechanism is provided on the housing, one end of which is connected to a damping block so that the damping block slides along the slider direction and contacts the side wall of the slider.

[0009] Preferably, the drive mechanism includes a coaxially linked displacement rod, a driving gear, a driven gear, and a threaded rod. The displacement rod has a reciprocating sliding stroke along the axis of the damping block. The driving gear forms a rigid transmission pair with the displacement rod through a keyway structure. The driven gear and the driving gear form a meshing transmission group. The end of the threaded rod is provided with a shoulder structure that mates with the inner hole of the driven gear, and the rod body is machined with a lead that matches the internal thread of the damping block.

[0010] Preferably, a limiting rod is fixedly connected inside the housing, and the limiting rod is slidably connected to the damping block.

[0011] Preferably, a bearing seat is fixedly connected inside the housing, and a bearing is provided inside the bearing seat and connected to a threaded rod to form a support point.

[0012] Preferably, the displacement rod is elastically reciprocatingly slidably connected to a limiting rod. When the limiting rod slides axially along the direction of the housing and connects with one of the limiting holes evenly distributed on the circumference of the housing, a circumferential rotation limiting of the displacement rod is formed.

[0013] Preferably, a limiting block is fixedly connected inside the housing, which abuts against the damping block to limit the damping block.

[0014] Preferably, the massage module includes a massage rod and a rotating ball. The massage rod is evenly distributed around the circumference of the massage execution plate, and the rotating ball rotates to the end of the massage rod near the palm.

[0015] Preferably, the massage rod is segmented, with adjacent massage rods connected by threads.

[0016] The advantages of this invention compared to the prior art are as follows:

[0017] 1. By coupling the slider and the massage execution plate through the planar linkage transmission mechanism, the massage module achieves a compound motion trajectory (kneading, rotation and micro-vibration) in the palm area, accurately covering acupoints such as Laogong and Yuji, stimulating nerve endings and promoting local blood circulation;

[0018] 2. The segmented massage stick combined with the rotating ball design can adapt to different hand curvatures, avoiding pressure damage caused by single rigid contact;

[0019] 3. The transmission combination of linear toothed rail and bevel gear pair is adopted to convert the linear motion of the drive slider into the three-dimensional rotary motion of the massage execution plate, which improves the transmission efficiency and does not require reliance on a high-power motor.

[0020] 4. The dynamic coordination between the reduction gear set and the damping block enables graded adjustment of the applied force, reducing the risk of muscle fatigue;

[0021] 5. The damping block driven by the threaded rod, combined with the elastic limit rod, can automatically adjust the massage pressure according to the user's hand size to prevent overstretching of the joints;

[0022] 6. The mechanical interlock design of the limiting hole and the limiting block ensures that the movement amplitude of the massage execution plate is controllable and avoids mechanical overload caused by misoperation;

[0023] 7. The housing integrates bearing housings and planetary gear trains, reducing the space occupied by traditional multi-motor layouts and lowering the overall weight, making it suitable for home or outdoor use. Attached Figure Description

[0034] like Figures 1 to 5 Example 1:

[0035] A hand exercise device for preventing Alzheimer's disease, comprising:

[0036] The housing 1 and the drive slider 2 that slides therethrough, the drive slider 2 extending to the outside of the housing 1 on both sides, allow the patient to train their hands by pressing the slider 2 back and forth.

[0037] A pivotally mounted massage execution plate 3 is provided on the side wall of the housing 1. The massage execution plate 3 can rotate on the housing 1. The execution plate is kinematically coupled with the drive slider 2 through a planar linkage mechanism. The reciprocating movement of the slider 2 forms a drive source, which drives the massage execution plate 3 to rotate. This causes the massage module 5 welded to the massage execution plate 3 to rotate circumferentially, massaging the palm area to activate the hand muscles and nerves.

[0038] The planar linkage transmission mechanism 4 includes:

[0039] The main drive shaft, linear gear 7, and reduction gear set 8 are arranged in a rotary support manner. The main drive shaft is horizontally mounted in the inner cavity of the housing 1. The reduction gear set 8 is integrated in the middle of the shaft and meshes with the linear gear 7 welded to the slider 2. This allows the slider 2 to move back and forth vertically, driving the reduction gear set 8 to rotate and thus rotating the main drive shaft, thereby achieving the driving of the main drive shaft. The reduction gear set 8 is a spur gear, which is fixed to the main drive shaft by a key.

[0040] The bevel gear pair 25 and the driven transmission rod 10 form a power steering transmission through the main drive shaft. When the drive shaft is driven to rotate by the power source, the corresponding bevel gear pair 25 rotates, which drives the driven transmission rod 10, which is welded to the input end of the bevel gear pair 25, to rotate. This causes the output end of the driven transmission rod 10 to drive the massage execution plate 3, which is fixed to its output end, to rotate. The massage execution plate 3 serves as the power transmission point, driving the massage module 5 to rotate in the palm to massage the palm. This can provide both motor training for the patient's fingers and muscle massage and nerve activation for the patient's palm. The bevel gear pair 25 consists of two meshing bevel gears. One bevel gear is keyed to the active transmission rod, and the other bevel gear is keyed to the driven transmission rod 10, forming the steering motion of the power source.

[0041] Example 2:

[0042] According to the above embodiment 1, a damping drive mechanism 11 is added. The drive mechanism 11 is set in the housing 1 and one end is connected to the damping block 12. It can make the damping block 12 move along the direction of the slider 2 in the housing 1 and increase the damping of the slider 2 when it contacts the surface of the slider 2, so as to increase the difficulty of the slider 2 displacement and thus meet the individualized training requirements of the patient.

[0043] The drive mechanism 11 includes a coaxially linked displacement rod 13, a drive gear 14, a driven gear 15, and a threaded rod 16. The displacement rod 13 is set along the axis of the damping block 12 and has a reciprocating sliding stroke to drive the transmission pair connected to the rod body of the displacement rod 13 to move, so that it can mesh with the driven gear 15 rotating in the housing 1. The rotation of the rod body causes the drive gear 14 to rotate in conjunction with the driven gear 15, which drives the threaded rod 16 welded to the driven gear 15 to drive the damping block 12, which is threadedly connected to the threaded rod 16, to move and contact the slider 2 surface, forming a sliding damping effect. When the damping block 12 is driven to move by the threaded rod 16, the limiting slide rod 20 welded in the housing 1 is slidably connected to the damping block 12, so that the limiting slide rod 20 can limit the rotation of the damping block 12 and prevent the damping block 12 from being affected by the threaded rod 16 during displacement.

[0044] Specifically, a bearing seat 18 is screwed into the housing 1, and the inner ring of the bearing 19 inside the bearing seat 18 is interference-fitted with the threaded rod 16, so that the bearing seat 18 can support the threaded rod 16.

[0045] Specifically, when the displacement rod 13 rotates to a certain position, the spring drives the limiting rod 17, which slides on the displacement rod 13, to enter one of the limiting holes 21 arranged circumferentially on the housing 1, so that the limiting hole 21 and the limiting rod 17 can limit the circumferential rotation of the displacement rod 13.

[0046] Specifically, a limiting block 22 is welded inside the housing 1, which can abut against the damping block 12 to limit the damping block 12.

[0047] Specifically, the massage module 5 includes a massage rod 23 and a rotating ball 24. The massage rod 23 is evenly distributed around the massage execution plate 3, and the rotating ball 24 rotates at the end of the massage rod 23 near the palm, reducing the friction between the massage rod 23 and the palm.

[0048] Specifically, the massage rod 23 is segmented, and adjacent massage rods 23 are connected by threads, which makes it easy for people to adjust the length of the massage rod 23.

[0049] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
