Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rehabilitation training technology, and mainly relates to a hand balance training device. Background Technology
[0002] Finger dexterity is an important aspect of evaluating hand motor ability and has a significant impact on people's normal lives.
[0003] In the field of medical rehabilitation, improving finger dexterity is an important part of rehabilitation treatment for patients whose hand movements are weakened or lost due to neurological diseases (such as stroke, Parkinson's disease, etc.), rheumatoid arthritis, or spinal cord injury.
[0004] In the field of surgery, the restoration of finger dexterity is the core goal of functional rehabilitation after hand and finger surgeries (such as tendon repair, nerve anastomosis, and internal fixation of fractures). In the early postoperative period, due to local swelling, pain, and the need for immobilization caused by surgical trauma, the fingers are often in a passively fixed state, which can easily lead to complications such as joint capsule contracture and tendon adhesions, directly affecting the range of motion of the fingers and fine motor skills. For example, in patients who have undergone flexor tendon rupture repair surgery, if they do not receive timely and scientific dexterity training, the incidence of tendon adhesions can be as high as 30% or more. In severe cases, a second surgery may be required to release the tendon adhesions, which not only prolongs the recovery period but also significantly reduces the patient's quality of life.
[0005] Meanwhile, during a child's growth and development, the development of finger dexterity is an important indicator of the maturation of their nervous system, the improvement of their cognitive abilities, and the progress of their limb coordination, and has a profound impact on a child's growth in multiple dimensions.
[0006] Fine motor skills of the fingers are closely linked to the language center in the brain. When children engage in activities requiring finger coordination, such as buttoning buttons or tying shoelaces, they indirectly stimulate the development of language-related areas, helping to improve the fluency and accuracy of their language expression. In group activities, children with dexterous fingers can more easily participate in cooperative games such as origami and building blocks. Through interaction and communication with peers, they enhance their teamwork awareness and social confidence, which is crucial for their integration into the group and the establishment of good interpersonal relationships.
[0007] Therefore, there is an urgent practical need to develop an innovative training device that can effectively improve finger dexterity. Utility Model Content
[0008] This invention provides a hand balance training device to solve the problem of the lack of finger dexterity training devices in the prior art.
[0009] To solve the above problems, the present invention adopts the following technical solution:
[0010] A hand balance training device includes a housing, a support member disposed on the housing, and a control member. The control member is used to control the movement of the support member on the housing. A tablet computer is placed on the support member. The tablet computer has a built-in gravity game. The user plays the gravity game by operating the control member.
[0011] The control component includes a first rotating shaft and a second rotating shaft rotatably mounted on the housing and extending to the outside of the housing. The first rotating shaft is hinged to the support member about an axis extending in the horizontal direction. The hinge axis of the first rotating shaft is coaxial with the axis of the second rotating shaft. The first rotating shaft rotates to drive the support member to adjust the angle between it and the horizontal plane in the first direction.
[0012] The support member has two relatively parallel and spaced-apart stop planes that extend vertically. A second rotating shaft extends between the two stop planes and has two mating planes that press against the corresponding stop planes. The second rotating shaft rotates to drive the support member to adjust the angle between it and the horizontal plane in the second direction. The first direction and the second direction are perpendicular to each other.
[0013] It has the following beneficial effects: When users rotate the first and second axes with their fingers, they can precisely control the rotation angle and force. This small-amplitude, controllable rotation operation trains the dexterity and force perception of the fingers. If the virtual object in the gravity game needs to move slowly along a straight line, the user needs to fine-tune the first and second axes with their fingers to ensure that the tilt angle of the support is stable within a very small range. This requires the fingers to avoid unnecessary movements and precisely control the force intensity, directly exercising the fingers and thus enhancing their dexterity.
[0014] Furthermore, the housing includes an upper shell and a lower shell that are detachably connected together, with an installation space between the upper shell and the lower shell, and the control components are assembled in the upper shell within the installation space;
[0015] The upper shell is provided with a clearance groove, and the first rotating shaft and the second rotating shaft are connected to the support member through the clearance groove. The first rotating shaft and the second rotating shaft are rotatably assembled on the upper shell.
[0016] It has the following advantages: the housing consists of an upper shell and a lower shell connected by a detachable connection, and the control components are assembled in the installation space of the upper shell. When the control components are damaged, the user can directly expose the control components in the installation space by separating the lower shell, and can carry out repair or replacement without damaging the overall structure of the housing.
[0017] Furthermore, the upper shell within the installation space is fixedly equipped with multiple fixed seats, and the first rotating shaft and the second rotating shaft are rotatably assembled with the corresponding fixed seats.
[0018] It has the following beneficial effects: the independent fixed base can ensure the stability of the rotation axis of the first and second rotating shafts through more precise machining, and avoid the shaking or displacement of the first and second rotating shafts caused by deformation of the housing material or assembly errors.
[0019] Furthermore, the support includes a tray and a rotating block fixedly connected together. The tray is used to place a tablet computer, and the rotating block is provided with a hinge seat and a stop. The hinge seat is hinged to the first rotating shaft through a relief groove.
[0020] The stop plane is located on the stop member, and the stop member cooperates with the second rotating shaft through the clearance groove.
[0021] It has the following advantages: the tray area is larger than the rotating block and is located on the outside. Its large size design can provide ample space for the tablet computer. The larger contact area can distribute the weight of the tablet computer and prevent it from sliding or falling due to unstable placement.
[0022] Furthermore, the tray has positioning guards at its four corners, and the tablet computer is placed within the area enclosed by the positioning guards.
[0023] It has the following beneficial effects: the positioning edge protector forms a physical constraint on the tablet computer by enclosing the area, preventing the tablet computer from shifting and preventing it from slipping off the edge of the tray and being damaged.
[0024] Furthermore, the first rotating shaft passes through the opposite sides of the upper shell, and the hinge seat is hinged to the middle position of the first rotating shaft;
[0025] There are two second rotating shafts, distributed on both sides of the axis of the first rotating shaft, and the two second rotating shafts are coaxial.
[0026] Furthermore, knobs are fixedly mounted on the ends of the first and second rotating shafts that extend out of the upper shell.
[0027] Furthermore, the first rotating shaft is the long shaft, and the second rotating shaft is the short shaft. Attached Figure Description

[0034] like Figures 1-3 As shown, a hand balance training device includes a housing 1, a support member disposed on the housing 1, and a control member. The control member controls the movement of the support member on the housing 1, thereby controlling the angle between the support member and the horizontal plane. A tablet computer is placed on the support member, and the tablet computer has a built-in gravity game. The user plays the gravity game by operating the control member. Through playing the gravity game, the user can improve finger dexterity; at the same time, the performance in the gravity game can also reflect the degree of finger dexterity.
[0035] In this embodiment, the control component includes a first rotating shaft 7 and a second rotating shaft 8 rotatably mounted on the housing 1 and extending to the outside of the housing 1, facilitating manual operation of the first rotating shaft 7 and the second rotating shaft 8 by the user from the outside of the housing 1. The first rotating shaft 7 is the longer shaft, and the second rotating shaft 8 is the shorter shaft; the length of the first rotating shaft 7 is greater than the length of the second rotating shaft 8. The first rotating shaft 7 is hinged to the support member about a horizontally extending axis. The hinge axis of the first rotating shaft 7 is coaxial with the axis of the second rotating shaft 8, and the hinge axis of the first rotating shaft 7 is perpendicular to the axis of the first rotating shaft 7 itself. The axis of the first rotating shaft 7 is also perpendicular to the axis of the second rotating shaft 8 itself. Rotation of the first rotating shaft 7 drives the support member to rotate through its hinge, thereby adjusting the angle between the support member and the horizontal plane in a first direction.
[0036] In this embodiment, as Figure 3 , Figure 4 As shown, the support member has a through groove 16 with a bottom and two parallel and spaced-apart walls, which are stop planes 18. A gap exists between the two stop planes 18. The second rotating shaft 8 includes a circular segment 14 and a square segment 15. The circular segment 14 of the second rotating shaft 8 is rotatably assembled with the housing 1. The stop planes 18 extend vertically and are parallel to the hinge axis of the first rotating shaft 7. The square segment 15 of the second rotating shaft 8 extends into the gap between the two stop planes 18, i.e., it extends into the through groove 16. The square segment 15 has two mating planes 17 that press against the corresponding stop planes 18. When the second rotating shaft 8 rotates, the mating planes 17 press against the stop planes 18, causing the support member to rotate, thereby adjusting the angle between the support member and the horizontal plane in the second direction.
[0037] In this embodiment, the first direction and the second direction are perpendicular to each other, and the first direction is the left-right direction, while the second direction is the front-back direction.
[0038] In other embodiments, the first direction and the second direction can be any direction, but they must satisfy the condition that the first direction and the second direction are perpendicular to each other.
[0039] For example, driving the first rotating shaft 7 to rotate on the housing 1 adjusts the angle between the support member and the horizontal plane in the first direction. Since the second rotating shaft 8 is engaged with the stop plane 18 through the pressing fit of the mating plane 17, the mating plane 17 and the stop plane 18 will slide relative to each other. Therefore, the second rotating shaft 8 will not affect the rotation of the support member.
[0040] When the second rotating shaft 8 is driven to rotate on the housing 1, the second rotating shaft 8 will drive the support member to rotate due to the pressing engagement between the mating plane 17 and the stopping plane 18, thereby adjusting the angle between the support member and the horizontal plane in the second direction. Since the first rotating shaft 7 is hinged to the support member, and the hinge axis of the first rotating shaft 7 is coaxial with the axis of the second rotating shaft 8 itself, when the second rotating shaft 8 is driven to rotate, the support member will rotate relative to the first rotating shaft 7 at the hinge point. Therefore, the first rotating shaft 7 will not affect the rotation of the support member.
[0041] Users need to precisely control the rotation angle and force when rotating the first axis 7 and the second axis 8 with their fingers. This small-amplitude, controllable rotation operation trains finger dexterity and force perception. For example, if a game requires a virtual object to move slowly along a straight line, the user needs to fine-tune the first axis 7 and the second axis 8 with their fingers to ensure that the tilt angle of the support is stable within a very small range. This requires the fingers to avoid unnecessary movements and precisely control the intensity of force, directly exercising the fingers.
[0042] The first rotating axis 7 and the second rotating axis 8 are two independently operable control components. When the first rotating axis 7 rotates, the second rotating axis 8 slides relative to it, and when the second rotating axis 8 rotates, the hinge of the first rotating axis 7 rotates relative to it. In gravity games, the movement of virtual objects requires adjusting the angles in the left-right and forward-backward directions simultaneously. This requires the user to use different fingers to operate the two rotating axes 7 and 8 respectively to achieve coordinated control in both directions.
[0043] In this embodiment, the housing 1 includes an upper housing 2 and a lower housing 3 detachably connected by screws. There is an installation space between the upper housing 2 and the lower housing 3, which is large enough to accommodate a control component. The control component is assembled in the upper housing 2 within the installation space. In this embodiment, if the control component is damaged, it can be repaired by removing the lower housing 3, thereby allowing the control component fixed to the upper housing 2 to be repaired.
[0044] The upper shell 2 is provided with a clearance groove 9. The first rotating shaft 7 and the second rotating shaft 8 are connected to the support member through the clearance groove 9, thereby realizing the control member inside the shell 1 controlling the support member outside the shell 1. The circular segments 14 of the first rotating shaft 7 and the second rotating shaft 8 are rotatably assembled to the upper shell 2.
[0045] The housing 1 consists of an upper shell 2 and a lower shell 3, which are detachably connected by screws. The control components are assembled within the mounting space of the upper shell 2. When the control components are damaged, the user can remove the screws to separate the lower shell 3 and directly expose the control components within the mounting space for repair or replacement without damaging the overall structure of the housing 1. This design avoids the problem of traditional one-piece housing 1 requiring complete disassembly or even scrapping for repair, significantly reducing maintenance difficulty and cost.
[0046] Sufficient installation space is reserved between the upper shell 2 and the lower shell 3, and the control components are housed within it. This not only prevents the control components from being exposed to external factors such as dust and collisions, but also provides ample room for the rotation and hinge of the control components, preventing components from jamming or interfering due to limited space.
[0047] The clearance groove 9 of the upper shell 2 provides a reasonable channel for the connection between the first rotating shaft 7 and the second rotating shaft 8 and the support member, so that the control member inside the shell 1 can accurately drive the external support member. This ensures the force transmission path between the inside and outside, avoids hard friction or jamming between the first rotating shaft 7 and the second rotating shaft 8 and the shell 1, ensures the smoothness of the support member angle adjustment, and indirectly ensures the feedback accuracy of finger operation.
[0048] The upper shell 2 serves as the main load-bearing structure for the control components, while the lower shell 3 acts as a protective and enclosed component. The design, where the two are connected by screws, achieves a modular structure. During production, the upper shell 2 and lower shell 3 can be machined separately, and then the entire assembly can be completed through simple assembly, improving production efficiency. If the control components need to be replaced later, only the upper shell 2 and the components within the installation space need to be modified, while the lower shell 3 can remain unchanged, reducing the cost and complexity of product upgrades.
[0049] In this embodiment, the upper shell 2 within the installation space is fixedly equipped with multiple mounting bases 12, and the circular segments 14 of the first rotating shaft 7 and the second rotating shaft 8 are rotatably assembled with the corresponding mounting bases 12. The mounting bases 12 serve as rotational supports for the first rotating shaft 7 and the second rotating shaft 8, and also bear the weight of the entire support component, as well as the weight of the tablet computer.
[0050] The fixed base 12 serves as a rotational support structure for the first rotating shaft 7 and the second rotating shaft 8, providing rigid and precise positioning of their rotational axes. Compared to the direct rotational assembly of the first rotating shaft 7 and the second rotating shaft 8 to the housing 1, the fixed base 12 can ensure the stability of the rotational axes of the first rotating shaft 7 and the second rotating shaft 8 through more precise machining, avoiding wobbling or displacement of the first rotating shaft 7 and the second rotating shaft 8 due to deformation of the housing 1 material or assembly errors.
[0051] In this embodiment, the support includes a tray 4 and a rotating block 13 fixedly connected together. The area of the tray 4 is larger than the area of the rotating block 13, and the rotating block 13 is located in the center of the tray 4. The tray 4 is used to place a tablet computer. The rotating block 13 is provided with a hinge seat 10 and a stop 11, both of which are located at positions corresponding to the clearance groove 9. The hinge seat 10 is hinged to the first rotating shaft 7 through the clearance groove 9, or in other words, the first rotating shaft 7 is hinged to the rotating block 13 through the hinge seat 10. The through groove 16 is located on the stop 11, that is, the stop plane 18 is also located on the stop 11. The stop 11 cooperates with the second rotating shaft 8 through the clearance groove 9, or in other words, the second rotating shaft 8 cooperates with the rotating block 13 through the stop 11.
[0052] In other embodiments, the rotating block 13 is not located in the exact center of the tray 4, but in other positions on the tray 4 besides the exact center.
[0053] In this embodiment, the tray 4 has a larger area than the rotating block 13 and is located on the outer side. Its large size provides ample space for the tablet computer and distributes its weight through a larger contact area, preventing slippage or falls due to unstable placement. At the same time, the tray 4 is located in the center of the rotating block 13, ensuring that the center of gravity of the tablet computer is approximately aligned with the rotation center of the support, reducing operational jamming of the first and second rotating shafts 7 and 8 caused by center of gravity shift.
[0054] The rotating block 13 is small in size and located in the center of the support plate 4. The hinge seat 10 and the stop 11 on it can accurately correspond to the position of the clearance groove 9 of the upper shell 2, ensuring that the force transmission path of the first rotating shaft 7 and the second rotating shaft 8 is without deviation.
[0055] In this embodiment, the support plate 4 and the rotating block 13 are fixedly connected by screws, which facilitates separate processing during production and reduces manufacturing difficulty; if a component is damaged, it can be replaced individually without replacing the entire support, thus reducing maintenance costs.
[0056] In this embodiment, the four corners of the tray 4 are provided with positioning guards 5. The positioning guards 5 are located on the side of the tray 4 away from the rotating block 13, that is, the positioning guards 5 are located on the outside of the housing 1. The tablet computer is placed in the area enclosed by the positioning guards 5 to prevent the tablet computer from sliding off the tray 4 when the angle of the tray 4 is adjusted.
[0057] The positioning guard 5 forms a physical constraint on the tablet computer by enclosing an area. When the user operates the first pivot 7 and the second pivot 8 to adjust the angle of the tray 4, the tablet computer may slide in the tilt direction due to gravity. The positioning guard 5 blocks the displacement of the tablet computer in the vertical direction, preventing it from slipping off the edge of the tray 4 and being damaged.
[0058] The core mechanism of gravity-based games is to use the tablet's built-in gravity sensor to detect changes in the angle of the support components, thereby providing feedback on the movement of virtual objects. The positioning guard 5 ensures the tablet's stable position on the tray 4, preventing angular deviations caused by sliding.
[0059] In this embodiment, the first rotating shaft 7 passes through the opposite sides of the upper shell 2, and the hinge seat 10 is hinged to the middle position of the first rotating shaft 7. At the same time, the hinge seat 10 is located in the middle of the rotating block 13. There are two second rotating shafts 8, which are distributed on both sides of the axis of the first rotating shaft 7, and the two second rotating shafts 8 are coaxial.
[0060] A knob 6 is fixedly mounted on the end of the first rotating shaft 7 and the second rotating shaft 8 that extends out of the housing 1. The knob 6 is located on the outside of the housing 1. When the user wants to rotate the first rotating shaft 7 and the second rotating shaft 8, he / she can hold the knob 6 and rotate the corresponding first rotating shaft 7 and the second rotating shaft 8. The knob 6 is provided with anti-slip pattern to prevent slippage when rotating.
[0061] In this embodiment, the knob 6 serves as the direct contact component between the first pivot 7 and the second pivot 8 and the fingers. Compared to directly rotating the first pivot 7 and the second pivot 8, the knob 6 is larger, providing a more comfortable grip area for the fingers. Users can more easily apply rotational force when holding the knob, making it particularly suitable for users with weaker finger strength or those needing to improve their dexterity.
[0062] The anti-slip pattern increases the friction between the finger and the knob 6, improving the stability of operation and ensuring that the force applied by the finger can be accurately transmitted to the knob 6, the first pivot 7 and the second pivot 8, reducing operation errors.
[0063] The working process of this utility model is as follows:
[0064] The first rotating shaft 7 is driven to rotate on the housing 1, thereby adjusting the angle between the support member and the horizontal plane in the first direction. Since the second rotating shaft 8 is engaged with the mating plane 17 and the stopping plane 18 through the pressing fit, the mating plane 17 and the stopping plane 18 will slide relative to each other, so the second rotating shaft 8 will not affect the rotation of the support member.
[0065] When the second rotating shaft 8 is driven to rotate on the housing 1, the second rotating shaft 8 will drive the support member to rotate due to the pressing engagement between the mating plane 17 and the stopping plane 18, thereby adjusting the angle between the support member and the horizontal plane in the second direction. Since the first rotating shaft 7 is hinged to the support member, and the hinge axis of the first rotating shaft 7 is coaxial with the axis of the second rotating shaft 8 itself, when the second rotating shaft 8 is driven to rotate, the support member will rotate relative to the first rotating shaft 7 at the hinge point. Therefore, the first rotating shaft 7 will not affect the rotation of the support member.
[0066] Adjusting the support in the first and second directions improves finger dexterity.
