Description

Technical Field

[0001] The present invention relates to the technical field of nursing instruments, and particularly relates to a hand exercise device for the elderly rehabilitation department. Background Art

[0002] With the increase of age, the elderly often suffer from hand dysfunction due to sequelae of stroke, Parkinson's disease or osteoarthritis, manifested as joint stiffness, muscle strength decline and loss of coordination, seriously affecting daily living abilities such as buttoning and using chopsticks;

[0003] The existing synchronous drive mode is based on a rigid link mechanism or a series pneumatic circuit, which forcibly realizes the mechanical linkage of multiple finger joints. In actual use, due to the different conditions of different patients, when encountering patients with diseased joints who often lose this physiological linkage ability due to tendon adhesion or abnormal muscle tension, the synchronous drive device will apply passive linkage when the patient has not yet recovered the joint coordination function, which may induce abnormal movement patterns and cause excessive stretching of high-tension joints, resulting in secondary injuries;

[0004] Therefore, in view of the above problems, a hand exercise device for the elderly rehabilitation department is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art and provide a hand exercise device for the elderly rehabilitation department.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme: A hand exercise device for the elderly rehabilitation department, including a first top cover, a second top cover, a third top cover and a fourth top cover:

[0007] A bending drive assembly, the bending drive assembly includes a mounting frame fixedly connected to the first top cover, the second top cover, the third top cover and the fourth top cover, a connecting column fixedly connected to the bottom end of the mounting frame, a first link block rotatably connected to the outside of the connecting column, a rotating shaft rotatably connected to the outside of the first link block, a second link block fixedly connected to the outside of the rotating shaft, and a fixing assembly fixedly connected to the outside of the bending drive assembly;

[0008] A finger fitting assembly, the finger fitting assembly includes a second finger link block fixedly connected to the second link block, an elongated link plate fixedly connected to the outside of the second finger link block, an extension shaft rotatably connected to the bottom end of the elongated link plate, and a splint fixedly connected to the outside of the extension shaft.

[0009] The technical effects of adopting the above technical solution are as follows: The cylinder drives the connecting rod to drive the first connecting block to rotate around the axis of the connecting column. The rotating shaft rotates accordingly and drives the cross bar to deflect through the second connecting block. At the same time, the motor drives the extension shaft to drive the clamping plate to converge centripetally. The arc-shaped support block, the outer abutting plate, the tiger mouth abutting block and the thumb top cover form multi-point positioning support, so as to realize the linkage of the active bending and passive fitting of the finger. The arc-shaped support block adapts to the arc of the back of the hand through the elastic deformation of the hollow groove. The outer abutting plate and the tiger mouth abutting block form three-point positioning. The thumb top cover rotates through the rotating column and the thumb connecting plate to provide stable and comfortable support for the hand. The rotational movement of the rotating shaft is transmitted to the cross bar through the second connecting block, causing the entire fixing assembly to deflect. The central column serves as the rotation reference point to maintain the stability of the movement track. The rotating column at the bottom of the cross bar forms a hinge point with the first connecting block to ensure the angle compensation during the movement of different finger joints.

[0010] Preferably, a lengthening connecting plate is fixedly connected to the outer side of the second finger connecting block, and a middle finger lengthening plate is fixedly connected to the outer side of the first connecting block on the second top cover. Motors are installed at the bottom ends of both the second finger connecting block and the lengthening connecting plate.

[0011] The technical effects of adopting the above technical solution are as follows: The lengthening connecting plate and the middle finger lengthening plate extend the length of the finger fitting assembly, better fitting the finger length and providing installation positions for components such as the clamping plate and the motor. The motors are installed at the bottom ends of the second finger connecting block and the lengthening connecting plate, driving the extension shaft to drive the clamping plate to converge centripetally. The gasket inside the clamping plate generates a flexible clamping force to realize the restraint and traction of the finger joint. Cooperating with the multi-point positioning support formed by the arc-shaped support block, the outer abutting plate, the tiger mouth abutting block and the thumb top cover, and the cylinder driving the connecting rod to drive the first connecting block to rotate around the axis of the connecting column, the rotating shaft rotates and drives the cross bar to deflect through the second connecting block, causing the entire fixing assembly to generate a deflection action. The central column serves as the rotation reference point to maintain the stability of the movement track. The rotating column at the bottom of the cross bar forms a hinge point with the first connecting block to ensure the angle compensation during the movement of different finger joints, realizing the linkage of the active bending and passive fitting of the finger.

[0012] Preferably, the driving end of the motor is fixedly connected to the extension shaft, and a gasket is fixedly connected to the inner side of the clamping plate.

[0013] The technical effects of adopting the above technical solution are as follows: By clamping the finger flexibly, the discomfort caused by hard compression is reduced, the exercise comfort is improved, the diseased joint is better protected, the risk of secondary injury is reduced, and the problem that the existing synchronous drive device is prone to induce abnormal movement patterns is effectively improved.

[0014] Preferably, fixing blocks are fixedly connected to the bottom ends of both the second finger connecting block and the lengthening connecting plate, and the end of the extension shaft away from the motor is rotatably connected to the fixing block.

[0015] The technical effect of adopting the above technical solution is: the fixed block provides a stable fulcrum for the extension shaft, enabling it to rotate smoothly, ensuring that the splint moves more accurately when fitting the fingers. This structure enhances the stability of the finger fitting assembly and effectively prevents problems such as uneven splint clamping force or unstable force on the fingers due to shaking of the extension shaft.

[0016] Preferably, the fixing assembly comprises a cross bar fixedly connected to the first link block, a center column is fixedly connected inside the cross bar, and rotating columns are fixedly connected on both sides of the bottom end of the cross bar.

[0017] The technical effect of adopting the above technical solution is: such a design realizes an independent adjustment mode for the second finger joint, ensuring that a designated training plan can be carried out according to the recovery situation of each different user.

[0018] Preferably, the outer side of the rotating column is fixedly connected to the first connecting block.

[0019] The technical effect of adopting the above technical solution is: the connection between the rotating column and the first connecting block reduces the relative displacement and shaking of the components, making the device more stable, and the rotating column can effectively transmit and disperse the force of the first connecting block to avoid excessive local force.

[0020] Preferably, a cylinder is fixedly connected to the outer side of the cross bar, and a connecting rod is fixedly connected to the driving end of the cylinder.

[0021] The technical effect of adopting the above technical solution is that the cylinder can provide stable and accurate power output for the bending and stretching movements of the fingers. When the cylinder is started, the linear motion of the driving end is transmitted through the connecting rod, driving the finger fitting component to achieve the bending or stretching of the fingers, ensuring the continuity of the finger exercise movements.

[0022] Preferably, a palm-back fitting component comprises arcuate support blocks respectively fixedly connected to the first top cover, the second top cover, the third top cover and the fourth top cover, wherein a hollow groove is provided inside the arcuate support blocks, wherein the bottom ends of two of the arcuate support blocks are fixedly connected to outer abutment plates, and the bottom ends of the other two arcuate support blocks are fixedly connected to tiger's mouth abutment blocks.

[0023] The technical effect of adopting the above technical scheme is: the second finger joint block of the finger fitting assembly is fixedly connected to the second joint block, the extended joint plate is fixedly connected to the outside of the second finger joint block, the middle finger extension plate is fixedly connected to the outside of the first joint block on the second top cover, the motor drives the extension shaft to drive the splint to contract centripetally, and the gasket on the inside of the splint generates a flexible clamping force.

[0024] Preferably, a thumb connecting plate is fixedly connected to the outer side of the first top cover, a rotating column is fixedly connected to the outer side of the thumb connecting plate, and a thumb top cover is rotatably connected to the outer side of the rotating column.

[0025] The technical effects of adopting the above technical solution are as follows: The thumb top cover is connected to the thumb connecting plate through the rotating column and can rotate flexibly around the rotating column. At the same time, the thumb connecting plate is fixedly connected to the outside of the first top cover, providing a stable support for the rotating column and the thumb top cover to ensure the stable movement of the thumb top cover.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. When the air cylinder starts, the driving end generates a linear thrust through the connecting rod, driving the first connecting block to rotate around the axis of the connecting column. The rotating shaft rotates accordingly, and the rotational movement is transmitted to the cross bar through the second connecting block, causing the overall fixed assembly to deflect; With such a design, the active bending action of the finger can be achieved, and the stabilizing effect of the central column ensures the accuracy and stability of the finger movement. In the case where the joint coordination function of the patient has not recovered, the problem of easily inducing abnormal movement patterns is solved by driving a single joint movement with the air cylinder, reducing the risk of excessive stretching of the high-tension joint and reducing the possibility of secondary injury to the patient;

[0028] 2. When the motor starts, the driving extension shaft rotates under the support of the fixed block, thereby driving the splints to converge centripetally. The gaskets on the inner sides of the splints generate a flexible clamping force, and with the extended support of the middle finger extension plate, the restraint and traction of the finger joint are achieved; With such a design, the passive fitting action of the finger can be realized by the cooperation of the motor and the splints. The flexible clamping force of the gaskets can increase the friction and comfort between the finger and the splints, reducing the discomfort of the finger during the exercise process. At the same time, the middle finger extension plate provides better support for the second finger joint, making the fitting of the second finger joint more stable;

[0029] 3. The arc-shaped support block adapts to the curvature of the palm back through the elastic deformation of the hollow groove, and the outer side pressing plate and the thumb web block form a three-point positioning. The thumb top cover rotates with the thumb connecting plate through the rotating column; With such a design, the arc-shaped support block can be adjusted adaptively according to the shape of the hand to provide comfortable support. The three-point positioning design of the outer side pressing plate and the thumb web block effectively limits the lateral displacement of the hand, ensuring the stability of the hand during the exercise process.

At the same time, the cross bar 61 can transmit the movement of the first connecting block 53 to other parts of the fixing component 6. The central column 62 is fixedly connected to the inside of the cross bar 61, mainly playing a role in support and positioning, providing a central reference for the hand exercise device to ensure the symmetry and stability of the device. During the hand exercise process, the central column 62 can help maintain the correct position of the fingers and guide the movement direction of the fingers. The rotating columns 63 are fixedly connected to both sides of the bottom end of the cross bar 61, and their outer sides are fixedly connected to the first connecting block 53. The rotating columns 63 are mainly used to connect the cross bar 61 and the first connecting block 53 and allow the cross bar 61 and the fixing component 6 to rotate within a certain range. This rotational connection method can provide a certain degree of flexibility for the second key hand exercise, thus adapting to different movement angles and directions of fingers in different segments;

[0048] The finger fitting component 7 includes a second finger connecting block 71 fixedly connected to the second connecting block 55. An extended connecting plate 72 is fixedly connected to the outer side of the second finger connecting block 71.

The motor 74 is installed at the bottom end of the second finger connecting block 71 and the lengthening connecting plate 72, and its driving end is fixedly connected to the extension shaft 75. The motor 74 is the power source of the finger fitting component 7. By controlling the rotation of the motor 74, the rotation of the extension shaft 75 can be driven, thereby driving the clamping plate 76 to realize the fitting and releasing actions of the fingers. The extension shaft 75 is fixedly connected to the driving end of the motor 74, and the clamping plate 76 is fixedly connected to the outside of the extension shaft 75.

The clamping plate 76 is fixedly connected to the outside of the extension shaft 75, and the gasket 77 is fixedly connected to the inside of the clamping plate 76. The clamping plate 76 is in direct contact with the fingers, used to fix and guide the movement of the fingers, ensuring that the fingers maintain the correct posture and position during exercise. The gasket 77 is fixedly connected to the inside of the clamping plate 76, mainly used to increase the friction and comfort between the clamping plate 76 and the fingers. The gasket 77 can buffer the pressure of the clamping plate 76 on the fingers and reduce the discomfort of the fingers during exercise. The fixing block 78 is fixedly connected to the bottom end of the second finger connecting block 71 and the lengthening connecting plate 72. The end of the extension shaft 75 away from the motor 74 is rotatably connected to the fixing block 78.

A hollow groove 82 is opened inside the arc-shaped support block 81. The bottom ends of two of the arc-shaped support blocks 81 are fixedly connected with an outer side abutting plate 83, and the bottom ends of the other two arc-shaped support blocks 81 are fixedly connected with a thumb web abutting block 84. The outside of the first top cover 1 is fixedly connected with a thumb connecting plate 85, the outside of the thumb connecting plate 85 is fixedly connected with a rotating column 86, and the outside of the rotating column 86 is rotatably connected with a thumb top cover 87;

[0051] The arc-shaped support blocks 81 are respectively fixedly connected to each top cover. Their arc-shaped surfaces conform to the natural bending shape of the back of the hand, providing a support platform for the hand, enabling the back of the hand to be comfortably placed on the device. The hollow groove 82 is opened inside the arc-shaped support block 81, used to provide a squeezing space, thus avoiding the rigid contact from affecting the user experience. The outer side abutting plate 83 is fixedly connected to the bottom ends of the two arc-shaped support blocks 81, mainly used to abut against the outer side of the palm, providing a support point to help fix the position of the hand and prevent the hand from moving laterally during exercise. The tiger's mouth abutting block 84 is fixedly connected to the bottom ends of the other two arc-shaped support blocks 81, specifically used to abut against the tiger's mouth part. The tiger's mouth abutting block 84 can further fix the hand, ensuring the overall stability of the hand, helping to maintain the correct posture of the hand, especially in the exercise involving the movement of the thumb, and improving the exercise effect. The thumb connecting plate 85 is fixedly connected to the outside of the first top cover 1, mainly used to connect the thumb top cover 87 and the rotating column 86. The thumb connecting plate 85 provides a support and connection structure for the movement of the thumb. The rotating column 86 is fixedly connected to the outside of the thumb connecting plate 85, and the thumb top cover 87 is rotatably connected to its outside. The rotating column 86 enables the thumb top cover 87 to rotate within a certain range, thus adapting to the movement direction of the thumb.

[0052] Working principle;

[0053] As Figures 1-6 shown,

[0054] First, the arc-shaped support block 81 adapts to the dorsal arc of the palm through the elastic deformation of the hollow groove 82. The outer bottom plate 83 and the thumb web block 84 form a three-point positioning. The thumb top cover 87 rotates with the thumb connecting plate 85 through the rotating column 86. When the motor 74 is started, it drives the extension shaft 75 to rotate under the support of the fixed block 78, thereby driving the clamping plate 76 to converge centripetally. The gasket 77 inside the clamping plate 76 generates a flexible clamping force during this process, and with the extended support of the middle finger extension plate 73, it realizes the restraint and traction of the finger joints. Subsequently, when the cylinder 56 is started, its driving end generates a linear thrust through the connecting rod 561, and then drives the first connecting block 53 connected to the connecting rod 561 to rotate around the axis of the connecting column 52. The rotating shaft 54 rotates synchronously under the drive of the first connecting block 53. The rotational movement of the rotating shaft 54 is transmitted to the cross bar 61 through the second connecting block 55, causing the entire fixing assembly 6 to deflect. At this time, the central column 62 serves as a rotation reference point to maintain the stability of the movement trajectory. At the same time, the rotation of the second connecting block 55 drives the second finger connecting block 71 outside it to move synchronously. The lengthened connecting plate 72 forms a linkage under the drive of the second finger connecting block 71. During the movement transmission process, the mounting bracket 51 serves as the connection hub of each top cover and the drive assembly, and transmits the supporting force of the top cover system to the motion chain through the connecting column 52. The rotating column 63 at the bottom of the cross bar 61 forms a hinge point with the first connecting block 53, enabling the fixing assembly 6 to deflect adaptively in the plane to ensure angle compensation during the movement of different finger joints.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
