[0024] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0025] Combination Figure 1 As shown, this utility model proposes an upper limb rehabilitation training device, including a first support base 11, a second support base 12, a slide 30, a rotating component 40, a first driving component 50, and a second driving component 60.

[0026] A guide rail 20 is provided between the first support base 11 and the second support base 12, and a slide 30 is connected to the guide rail 20 and can move along the length of the guide rail 20.

[0027] The device's support frame is formed by the first support base 11, the second support base 12, and the guide rail 20, making the device compact and portable. The slide table 30 can move along the direction of the guide rail 20, providing users with a larger training space.

[0028] Furthermore, the turnover component 40 includes a connecting rod 42, the first end of which is rotatably connected to the slide table 30, and the second end of which is connected to a handle 41, which is rotatable relative to the connecting rod 42.

[0029] The rotation axis of the connecting rod 42 is perpendicular to the axis of the guide rail 20, and the rotation axis of the handle 41 is parallel to the rotation axis of the connecting rod 42.

[0030] In this way, the user can use the handle 41, which can make circular motion around the rotation center of the connecting rod 42. The circular trajectory formed by the handle 41 is parallel to the guide rail 20. During this process, the user's wrist, elbow and arm complete different degrees of flexion and extension movements, which may improve the rehabilitation training effect. At the same time, the entire slide 30 can also slide along the guide rail 20. Therefore, while completing the circular motion, it can also produce a large displacement in the linear direction, thereby achieving a compound rehabilitation training method that combines linear and rotational movements, thus improving the rehabilitation training effect.

[0031] Furthermore, the first drive component 50 is connected to the slide 30, and the second drive component 60 is connected to the slide 30.

[0032] The first driving component 50 is used to drive the connecting rod 42 to rotate around the slide table 30, and the second driving component 60 is used to drive the slide table 30 to move along the length direction of the guide rail 20.

[0033] Thus, the device can switch between active and passive exercise modes. When the first drive component 50 and the second drive component 60 are not in operation, the user can perform rehabilitation exercises in active exercise mode, that is, hold the handle 41 and make circular and linear movements. When one or both of the first drive component 50 and the second drive component 60 are in operation, the user's hand can be driven to make circular and / or linear movements after holding the handle 41 to perform rehabilitation training, so as to achieve different rehabilitation training effects.

[0034] In an optional embodiment, the bottoms of the first support 11 and the second support 12 can be at different heights, i.e., pads of different heights. In this way, when the user is training, especially when moving in a straight line, he / she can not only run on the plane at the current height, but also move to different heights to change the difficulty and length of the training.

[0035] Furthermore, a turntable 43 is provided on one side of the slide table 30. The turntable 43 is rotatably connected to the slide table 30, and the first end of the connecting rod 42 is detachably connected to the turntable 43.

[0036] Specifically, the center part of the turntable 43 has a protruding shaft, and the first end of the connecting rod 42 is provided with a bushing. The bushing can be used to connect or separate from the shaft. Different lengths of connecting rod 42 can be selected as needed. The different lengths of connecting rod 42 determine the diameter of the handle 41 when it makes a circular motion. By changing the length of the connecting rod 42, the difficulty and effect of training can also be controlled.

[0037] Furthermore, the outer wall of the turntable 43 is provided with a toothed structure, and the output end of the first drive component 50 is provided with a gear 44. The gear 44 is meshed with the turntable 43 through the toothed structure, and the gear 44 can drive the turntable 43 to rotate.

[0038] Thus, the damping force generated by the meshing of gear 44 and turntable 43 ensures the smoothness of handle 41 during rotation.

[0039] Specifically, the first driving component 50 is a motor. During the rehabilitation training process in the active movement mode, the motor can drive the gear 44 to rotate at a predetermined speed, so that the turntable 43 rotates at the target speed.

[0040] In an optional embodiment, the second drive component 60 includes a linear transmission mechanism, which includes a connecting structure and a driver that drives the connecting structure to move along the axial direction of the guide rail 20, with the slide 30 connected to the connecting structure.

[0041] Optionally, the second drive component 60 includes a lead screw drive mechanism.

[0042] Combination Figure 2 and Figure 3As shown, the second drive component 60 includes a drive pulley 61, a timing belt 62, and an idler pulley 63. The drive pulley 61 is disposed in the second support base 12, the idler pulley 63 is disposed in the first support base 11, and the timing belt 62 is sleeved on the drive pulley 61 and the idler pulley 63. A clamping block 31 is provided on the slide table 30, which clamps one side of the timing belt 62 and keeps it relatively fixed to the timing belt 62.

[0043] Specifically, a motor is provided on one side of the drive pulley 61. The outer walls of both the drive pulley 61 and the inertial pulley 63 are provided with teeth, and the inner wall of the synchronous belt 62 is provided with teeth. When the drive pulley 61 is driven by the motor to rotate, the slide table 30 moves along the length direction of the guide rail 20 through the meshing of the teeth, ensuring that there is no slippage during the transmission process. The belt drive has the characteristics of low noise and stable and smooth transmission, which provides a good user experience.

[0044] Furthermore, the axes of both the drive pulley 61 and the inertial pulley 63 are perpendicular to the axis of the guide rail 20.

[0045] Specifically, there are two guide rails 20 and the guide rods 20 can be optical axes. The two optical axes are distributed on the left and right sides of the synchronous belt 62 and are at the same height. Therefore, the height of the slide table 30 can be reduced, which is beneficial to the miniaturization of the device.

[0046] In conjunction with the above embodiments, the upper limb rehabilitation training device proposed by this utility model, through the cooperation of rotating components and guide rail structure, enables users to hold the handle and perform circular and linear movements, achieving a composite rehabilitation training that combines linear and rotational movements. This allows patients to be trained in all directions, increases the angle and diversity of training activities, and improves the rehabilitation training effect. At the same time, the device is small and lightweight, making it suitable for most patients who need upper limb training.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
