Description

Technical Field

[0001] This application relates to the field of rehabilitation protective gear technology, and more particularly to a foot and ankle joint trainer. Background Technology

[0002] The ankle joint is an important bone joint in the human body. It is surrounded by numerous foot joints and muscles. For people with limited mobility, especially those who have lost their ability to move independently for a short or long period of time, prolonged inactivity of the ankle joint can lead to a series of problems such as ankle joint dysfunction, joint effusion, and atrophy of related muscles.

[0003] Currently, ankle rehabilitation braces have emerged to help users train their ankle joints. However, existing ankle joint rehabilitation braces need to both fix the user's foot and leg and assist the foot in moving relative to the leg to train the ankle joint. This results in a complex and space-consuming transmission structure in existing ankle joint rehabilitation devices, and the equipment cannot be shut down in time in case of an emergency. In addition, different users have different ankle joint sizes, but existing ankle rehabilitation braces are not adjustable to the usual size, making it difficult for users to wear them.

[0068] Please refer to the following: Figures 1 to 4The first embodiment of this application provides a foot and ankle joint trainer 1 for assisting users in training their foot and ankle joints. It includes a base 20, a transmission structure 10, a footplate 30, a telescopic support arm 40, a control structure 50, and a power supply structure 60. The base 20 supports and fixes the transmission structure 10, footplate 30, telescopic support arm 40, and control structure 50. The power supply structure 60 is separately configured from the base 20, transmission structure 10, footplate 30, telescopic support arm 40, and control structure 50, thus facilitating user charging of the power supply structure 60 and further reducing the size of the foot and ankle joint trainer 1. Simultaneously, the power supply structure 60 is equipped with an emergency switch 61, allowing users to position the power supply structure 60 in a more convenient hand-operated location, bypassing the control structure 50 to directly operate the power supply structure 60, enabling more stable, safe, and quick emergency shutdown and improving safety performance. The footplate 30 and the telescopic support arm 40 are connecting structures connecting the two sides of the ankle joint. The footplate 30 is used to support the foot. In use, the user rests on the footplate 30 and can be fixed by straps. Alternatively, the footplate 30 can be inserted into a shoe, and then the user puts on the shoe, fixing the foot and footplate 30 together. The telescopic support arm 40 is provided with a magnetic binding part 41, which can be used to easily and quickly bind the telescopic support arm 40 to the user's lower leg. At the same time, the telescopic support arm 40 can also be adjusted to accommodate the user's lower leg size, thereby improving the adaptability of the ankle joint trainer 1. It should be noted that the footplate 30 is connected to the base 20 through the transmission structure 10. The footplate 30 is not directly fixed to the base 20, while the telescopic support arm 40 is directly fixed to the base 20. That is, the base 20 can rotate relative to the base 20 under the drive of the transmission structure 10, thereby causing relative movement between the foot and lower leg, achieving ankle joint training. It is also known that the transmission structure 10 is disposed on the base 20, and the transmission structure 10 is configured as a horizontal bevel gear 12 and a vertical bevel gear 13 meshing with each other, so as to change the transmission direction with a simple and stable structure; wherein, one end of the foot plate 30 is connected to the vertical bevel gear 13; the foot plate 30 is driven to carry the user's foot to rotate, thereby training the foot and ankle joints; the control structure 50 is connected to both the power supply structure 60 and the transmission structure 10, and controls the operation of the power supply structure 60 and the transmission structure 10 to ensure the stable and safe operation of the foot and ankle joint trainer 1.

[0069] Please refer to the following: Figures 5 to 8In some preferred embodiments, the transmission structure 10 further includes a motor 11, which is electrically connected to both the control structure 50 and the power supply structure 60. The motor 11 is also connected to the horizontal bevel gear 12. That is, the transmission structure 10 includes a motor 11, a horizontal bevel gear 12, and a vertical bevel gear 13. One end of the horizontal bevel gear 12 is connected to the motor 11; one end of the vertical bevel gear 13 meshes with the horizontal bevel gear 12; and the other end of the vertical bevel gear 13 is connected to the foot plate 30. It can be seen that by using bevel gear components and providing two sets of vertically meshing bevel gear components, the power of the motor 11 can be transmitted through a 90-degree bend, effectively and smoothly replacing the existing chain drive or shaft drive structure 10, effectively reducing the volume of the transmission structure 10 and improving stability.

[0070] In some embodiments, the vertical bevel gear 13 includes: a vertical bevel body 131, a main drive shaft 132, a gear shaft synchronizing member 133, and a vertical bevel bearing 134; the vertical bevel body 131 meshes with the horizontal bevel gear 12; the main drive shaft 132 is coaxially arranged with the vertical bevel body 131, and the end of the main drive shaft 132 opposite to the vertical bevel body 131 is connected to the foot plate 30; the gear shaft synchronizing member 133 is arranged at the end of the vertical bevel body 131 opposite to the main drive shaft 132, and is limited in the circumferential direction along both the vertical bevel body 131 and the main drive shaft 132; the vertical bevel bearing 134 is sleeved on the main drive shaft 132.

[0071] It is understood that the horizontal bevel gear 12 transmits the power of the motor 11 to the vertical cone body 131. The vertical cone body 131 rotates synchronously with the main drive shaft 132 through the gear shaft synchronizing member 133, thereby transmitting the power of the motor 11 to the main drive shaft 132. With the assistance of the vertical cone bearing 134, the main drive shaft 132 smoothly drives the connecting foot plate 30 to rotate, thereby training the foot and ankle joints and related tissues.

[0072] In some embodiments, the gear shaft synchronizing member 133 includes: a clamping shaft 1331 and a clamping sleeve 1332; one end of the clamping shaft 1331 is circumferentially limited and connected to the main drive shaft 132, that is, the clamping shaft 1331 and the main drive shaft 132 rotate synchronously; the clamping sleeve 1332 is disposed on the clamping shaft 1331 and is circumferentially limited and connected to the clamping shaft 1331, that is, the clamping sleeve 1332, the clamping shaft 1331, and the main drive shaft 132 rotate synchronously; the clamping sleeve 1332 is circumferentially and axially limited and connected to the end of the vertical cone body 131 opposite to the main drive shaft 132; that is, the clamping sleeve 1332 is both circumferentially and axially limited and connected to the end of the vertical cone body 131 opposite to the main drive shaft 132. The vertical cone body 131 rotates synchronously, and the clamping sleeve 1332 is axially limited to the vertical cone body 131; thus, the synchronous rotation of the clamping sleeve 1332, clamping shaft 1331, main drive shaft 132 and vertical cone body 131 is finally achieved. The horizontal bevel gear 12 transmits the power of the motor 11 to the vertical cone body 131. The vertical cone body 131 transmits the power of the motor 11 to the clamping shaft 1331 through the clamping sleeve 1332. The clamping shaft 1331 transmits the power of the motor 11 to the main drive shaft 132. With the assistance of the vertical cone bearing 134, the main drive shaft 132 smoothly drives the connecting foot plate 30 to rotate, thereby training the ankle joint and related tissues.

[0073] In some embodiments, the clamping shaft 1331 includes: a clamping shaft body 131a and a circumferential limiting key 131b; the circumferential limiting key 131b is disposed on the end face of the clamping shaft body 131a facing the main drive shaft 132; it can be seen that the clamping shaft body 131a and the clamping sleeve 1332 are connected in a circumferential direction for limiting connection, and the clamping shaft body 131a achieves a circumferential connection with the main drive shaft 132 through the circumferential limiting key 131b, thereby ensuring that the clamping shaft body 131a and the main drive shaft 132 rotate synchronously in the circumferential direction.

[0074] Furthermore, the gear shaft synchronizing component 133 also includes a main shaft locking bolt 1333. A locking through hole 131c is axially formed at the center of the clamping shaft body 131a. The main shaft locking bolt 1333 is screwed into the locking through hole 131c and also screwed into the main drive shaft 132. It is understood that the axial extension length of the locking through hole 131c is less than the axial extension length of the main shaft locking bolt 1333. After passing through the locking through hole 131c, the main shaft locking bolt 1333 is screwed into the main drive shaft 132, thereby limiting and fixing the clamping shaft 1331 and the main drive shaft 132 axially, preventing the clamping shaft 1331 from detaching axially during rotation. The main drive shaft 132 causes the transmission structure 10 to malfunction. It should be noted that, due to the function of the circumferential limiting key 131b provided on the clamping shaft body 131a, the clamping shaft body 131a and the main drive shaft 132 rotate synchronously in the circumferential direction. The main shaft locking bolt 1333 also rotates synchronously in the circumferential direction with the clamping shaft body 131a and the main drive shaft 132, and will not rotate relative to either the clamping shaft body 131a or the main drive shaft 132 in the circumferential direction. Thus, with a simple and small-volume screw connection structure, a stable transmission connection between the clamping shaft 1331 and the main drive shaft 132 is ensured.

[0075] In some embodiments, the clamping sleeve 1332 includes: a clamping sleeve body 132a, a locking adjustment part 132d, a locking adjustment bolt 132e, a first circumferential limiting part 132f, and a second circumferential limiting part 132g; the clamping sleeve body 132a is provided with a sleeve hole 132b and a disconnection port 132c communicating with the sleeve hole 132b; the clamping sleeve body 132a is screwed to the vertical cone body 131, thereby simultaneously connecting the clamping sleeve body 132a with the vertical cone body 131. The vertical cone body 131 is simultaneously limited and connected in the axial and circumferential directions; it can be seen that the clamping sleeve body 132a has a fitting hole 132b along the axial direction, the clamping shaft 1331 is accommodated in the fitting hole 132b, and the clamping sleeve body 132a on the outer periphery of the fitting hole 132b is provided with a break opening 132c, so that when fitting the clamping shaft 1331, the hole diameter of the fitting hole 132b can be adjusted through the break opening 132c, which facilitates the fitting of the clamping shaft 1331. The locking adjustment part 132d is disposed on both sides of the disconnection port 132c, and the locking adjustment bolt 132e is screwed onto the locking adjustment part 132d. It can be seen that by providing the locking adjustment part 132d on both sides of the disconnection port 132c, for example, by setting the locking adjustment part 132d as a threaded hole that cooperates with the locking adjustment bolt 132e, and then after the clamping sleeve 1332 is sleeved on the clamping shaft 1331, the diameter of the sleeve hole 132b can be adjusted again by the locking adjustment part 132d and the locking adjustment bolt 132e, so that the clamping sleeve body 132a is further clamped on the clamping shaft 1331. The first circumferential limiting part 132f protrudes from the end face of the locking adjustment part 132d facing the vertical cone body 131, and the second circumferential limiting part 132g protrudes from the end of the clamping sleeve body 132a facing away from the locking adjustment bolt 132e towards the end face of the vertical cone body 131. The vertical cone body 131 is provided with a first limiting groove 1311 and a second limiting groove 1312.
