[0024] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained.

[0025] Refer to Figure 1 and Figure 2 , according to a preferred embodiment of the present invention, an upper limb rehabilitation training device includes a support frame and a frosted plate 11. The frosted plate 11 is installed on the support frame, and the height of the support frame is adjustable and is rotatably connected to the frosted plate 11.

[0026] The support frame includes a base 1, a lifting column 2, a support base 3 and a flipping adjustment mechanism. The flipping adjustment mechanism is located between the support base 3 and the frosted plate 11 and does not directly face the patient, improving the aesthetics while eliminating various exposed movement gaps and exposed cables, and improving the safety of use.

[0027] The support base 3 is installed on the base 1 through the lifting column 2. The lifting column 2 is used to adjust the height of the frosted plate 11 so that the training device can be suitable for patients of different body shapes. The specific structure of the lifting column 2 is not particularly limited in this embodiment. The lifting column 2 can be manually operated, and / or the lifting column 2 can be driven by a driving mechanism, such as a hydraulic cylinder with a liquid as the driving medium. When the hydraulic cylinder is used for the lifting column 2, the fixed end of the hydraulic cylinder is connected to the base 1, and the movable end is connected to the support base 3.

[0028] The flip adjustment mechanism includes a rotating seat 10, which is fixedly connected to the sanding plate 11 and can be rotated relative to the support seat 3 to adjust the inclination angle of the sanding plate 11, so as to help the patient achieve upper limb movements with different loads, which is beneficial to the patient's rehabilitation. In principle, the rotating seat 10 can implement compound movements, for example, with the help of a connecting rod mechanism. However, it is particularly advantageous and simple that the rotating seat 10 can implement a simple rotational movement. To this end, the rotating seat 10 can be flipped around a rotation axis extending in the length direction of the support seat 3. As an example, the rotating seat 10 has a rotating shaft, and the axis of the rotating shaft defines the rotation axis. In an advantageous embodiment, the rotating seat 10 can be configured as a frame, which includes two side plates spaced apart and parallel to each other in the length direction of the support seat 3, and the two side plates can be connected into one by a connecting rod, or the two side plates are respectively rotatably connected to the support seat 3.

[0029] The rotating seat 10 can be manually operated and / or can be driven by means of a driving mechanism, in particular an electric driving unit. In a preferred embodiment, the driving mechanism includes a pair of chain drive assemblies, which are respectively arranged on both sides of the length direction of the support seat 3, and the chain drive assembly includes a first sprocket 7 and a second sprocket 9 arranged at intervals along the width direction of the support seat 3, and the first sprocket 7 and the second sprocket 9 are respectively and independently connected to the support seat 3 through a bracket for rotation, and the first sprocket 7 and the second sprocket 9 are connected by a chain 8 for transmission. The sprocket close to the lower edge of the sanding plate 11 is defined as the second sprocket 9, and the rotating seat 10 is fixedly mounted on the second sprocket 9 through the rotating shaft, and the rotating shaft is arranged centrally on the end face of the second sprocket 9.

[0030] The chains 8 of a pair of chain drive assemblies are connected by a connecting rod 6, and the connecting rod 6 is configured to drive the chain 8 to perform linear motion along the width direction of the support seat 3. In principle, the driving mechanism can directly drive the sprocket to rotate, or directly drive the connecting rod 6 to perform linear motion. As an example, the driving mechanism also includes an electric push rod 4, which is installed on the support seat 3 and connected to the connecting rod 6, and is used to drive the connecting rod 6 to move along the width direction of the support seat 3. In this way, since the two ends of the connecting rod 6 are respectively fixed on the two chains 8, when the connecting rod 6 moves, the chain 8 moves accordingly, and drives the first sprocket 7 and the second sprocket 9 to rotate, and the second sprocket 9 rotates and drives the rotating seat 10 to rotate, so that the frosting plate 11 on the rotating seat 10 is flipped, thereby adjusting the inclination angle of the frosting plate 11.

[0031] A guide rail slider assembly 5 is also installed on the support base 3, and the guide rail slider assembly 5 is located between a pair of the chain drive assemblies. The guide rail slider assembly 5 includes a guide rail and a slider. The guide rail extends along the width direction of the support base 3. The upper part of the slider is connected to the connecting rod 6, and the lower part is slidably connected to the guide rail. In this way, on the one hand, the design of the guide rail slider assembly can reduce the looseness caused by the change of the tension of the chain 8. On the other hand, since the extending direction of the guide rail is determined, by establishing the connection between the connecting rod 6 and the slider on the guide rail, it can ensure that the connecting rod 6 always moves along a straight track, ensuring the movement stability of the connecting rod 6 and making the control of the inclination angle of the grinding plate 11 more accurate.

[0032] In an advantageous embodiment, a pair of guide rail slider assemblies are installed on the support base. The pair of guide rail slider assemblies are spaced apart along the length direction of the support base 3 and are respectively located on both sides of the support base 3. In this way, the force on the connecting rod 6 is more uniform and the movement is more stable.

[0033] The upper limb rehabilitation training device further includes an upper limb training module. The upper limb training module includes a trajectory recognition device and an accessory. The accessory is placed on the grinding plate 11, and the trajectory recognition device is used to recognize the position of the accessory on the grinding plate 11.

[0034] The trajectory recognition device includes an optical signal emitter and an optical signal receiver provided on the accessory. The optical signal emitter is used to emit an optical signal towards the grinding plate 11. As an example, the optical signal emitter is an infrared emitter and emits an infrared signal towards the grinding plate 11. The optical signal receiver faces the grinding plate 11 and receives the optical signals emitted by the optical signal emitter at different positions on the grinding plate 11. The optical signal receiver generates a position signal corresponding to the position of the optical signal source and emits the position signal externally. In this embodiment, the optical signal receiver is an infrared receiver and receives the infrared signal emitted by the infrared emitter on the accessory. The position signal includes a light source matrix coordinate value corresponding to the grinding plate 11, and the controller uses the coordinate of the highest coordinate value as the position of the accessory relative to the grinding plate 11.

[0035] The optical signal receiver is provided with a first Bluetooth module, which converts the position signal into a Bluetooth signal and emits it externally. The trajectory recognition device further includes a controller, and the controller is provided with a second Bluetooth module connected to the first Bluetooth module to receive the position signal emitted by the optical signal receiver and determine the current position of the accessory on the frosted board 11 according to the position signal. The controller also stores training trajectory data corresponding to the frosted board 11. The training trajectory data corresponds to a training track pattern of the frosted board 11, forms a plurality of moving fixed points, and a display track pattern is formed by the plurality of moving fixed points. Among them, the appearance of the display track pattern is the same as that of the training track pattern. In order to increase the fun of the patient during training, the display track pattern can be designed as a game pattern (such as a maze), so that the patient will not feel bored during the rehabilitation training.

[0036] The upper limb training module further includes a display, and the display is used to display the movement trajectory of the accessory according to the information fed back by the trajectory recognition device for the patient to directly visually observe.

[0037] It should be noted that the above embodiments can be freely combined according to needs. The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
