[0034] A clamping mechanism with the function of transverse movement of a vertical plate 40 is arranged on the fixed column 25. The clamping mechanism includes a motor 1 32, the rotating end of the motor 1 32 is fixedly connected with a positive and negative threaded rod 33, the positive and negative threaded rod 33 is rotationally connected with a vertical plate 40, an arc plate 41 is fixedly connected to the inner side of the vertical plate 40, the arc plate 41 is fixedly connected with a frame 42, a silicone layer 43 is bonded to one side of the frame 42, a sponge layer 45 is bonded to one side of the silicone layer 43, and a pressure sensor 44 is fixedly bonded to one side of the silicone layer 43.

[0035] A microphone 5 is installed on one side of the vertical plate 40.

[0036] Please refer to Figure 3, both ends of the seat board 100 are fixedly connected to the corresponding two side surfaces of the "U"-shaped column 103. Both sides of the top of the seat board 100 are fixedly connected with armrests 101. One side surface of the two armrests 101 is fixedly connected with a backboard 102 together. The included angle between the backboard 102 and the seat board 100 is 90 degrees, which can accurately fit the back of neck patients, provide stable support for the back, guide and prompt the patient's back to maintain a straight state, help correct bad sitting postures, and play a positive role in maintaining and improving the spinal health of the patient.

[0037] Please refer to Figure 2 , the bottom end of the "U"-shaped column 103 is fixedly connected to both sides of the bottom plate 104. Through holes are vertically opened in all four corners of the bottom plate 104. Expansion bolts 105 are respectively embedded in the four through holes. The seat board 100, armrests 101, backboard 102, "U"-shaped column 103, bottom plate 104 and expansion bolts 105 are combined into a sitting and standing assembly 1. The expansion bolts 105 are used to fix the bottom plate 104 and embed it in the foundation.

[0038] Please refer to Figure 2 , the top of the "U"-shaped column 103 is vertically fixedly connected to the input end of the electric push rod 20. The electric push rod 20 is externally connected to a power source. The electric push rod 20, connecting frame 21, linear module 22, motor 23, turntable 24 and fixed column 25 are combined into a moving and rotating assembly 2. The lifting of the electric push rod 20 drives the connecting frame 21 to lift synchronously. The synchronous lifting of the connecting frame 21 causes the linear module 22, motor 23 and transverse movement assembly 3 to lift synchronously.

[0039] Please refer to Figure 4 , the bottom end of the fixed column 25 is fixedly connected with a circular connection end 300. The circular connection end 300 is located in the middle of the sliding groove column 30. Both ends of the sliding groove column 30 are vertically fixedly connected with side plates 31. A through hole is penetrated through one of the side plates 31, and a rotating hole is opened in the other side plate 31. The main function of the circular connection end 300 is to connect the fixed column 25.

[0040] Please refer to Figure 4 , two vertical plates 40 are slidably connected to the sliding groove column 30. A forward thread 34 and a reverse thread 35 are respectively opened on the two vertical plates 40. A sliding groove 36 is horizontally penetrated through the vertical plates 40. The sliding groove 36 is slidably connected to the sliding groove column 30. The rotating end of the first motor 32 is located in the through hole of the side plate 31. Both ends of the forward and reverse threaded rod 33 are respectively rotatably connected to the through hole of the side plate 31 and the rotating hole of the other side plate 31. The relative rotation of the forward and reverse threaded rod 33 and the forward thread 34 and the reverse thread 35 is restricted by the sliding groove 36 and the sliding groove column 30, so that the vertical plates 40 can slide in the middle or move at both ends.

[0041] Please refer to Figure 5, the interior of the silica gel layer 43 is a cavity structure, a frame 42 is placed in the cavity of the silica gel layer 43, one side of the sponge layer 45 is attached to one end of the pressure sensor 44, and the vertical plate 40, the arc plate 41, the frame 42, the silica gel layer 43, the pressure sensor 44 and the sponge layer 45 are combined into a fixing component 4.

[0042] Please refer to Figure 7 , one end of the vertical plate 40 is fixedly connected to a serpentine tube, one end of the serpentine tube is fixedly sleeved with a microphone 5, and a voice acquisition module, an audio signal processing module, a voice recognition module, a control module and a driving module are installed in the microphone 5.

[0043] The implementation principle of a rehabilitation robot for neck movement in an embodiment of this application is as follows:

[0044] The neck patient sits on the seat plate 100, and the back of the neck patient leans against the back plate 102, which can make the back fit precisely against the back of the patient, provide a stable supporting force for the back, guide and prompt the patient to keep the back straight. Since the heights of each neck patient are different, the operator can position the patient's cheek by controlling the positions of the moving and rotating component 2, the transverse moving component 3 and the fixing component 4. The positioning process is as follows:

[0045] The sliding end of the linear module 22 slides to drive the motor 23, the turntable 24, the fixed column 25, the transverse moving component 3 and the fixing component 4 to slide back and forth. The output end of the electric push rod 20 extends from the input end, which can drive the connecting frame 21, the linear module 22, the motor 23, the turntable 24, the fixed column 25, the transverse moving component 3 and the fixing component 4 to move up and down. The motor 32 drives the forward and reverse threaded rod 33 to rotate, and the forward and reverse threaded rod 33 will make the forward thread 34 and the reverse thread 35, that is, the two vertical plates 40 slide to the center. Through moving up and down, moving horizontally and sliding back and forth, the vertical plate 40 can be locked at the cheek of the neck rehabilitation patient;

[0046] The continuous rotation of the motor 32 will make the silica gel layer 43 and the sponge layer 45 contact the patient's cheek. At the same time, the sponge layer 45 is squeezed to make the pressure sensor 44 sense. When the pressure sensor 44 reaches the pressure set value, the pressure sensor 44 will transmit a signal to the control module, and the control module will stop the rotation of the motor 32, so as to make the silica gel layer 43 and the sponge layer 45 fit against the patient's cheek to achieve fixation;

[0047] At this time, the patient can bend the microphone 5 to the mouth position through the flexible tube, and can exhale commands, such as turning the motor 23 forward and backward by 45 degrees, and can also control the start and stop of the motor 23 at any time. The voice exhaled by the patient passes through the voice acquisition module, the audio signal processing module, the voice recognition module, the control module and the drive module in sequence. At this time, the motor 23 rotates and drives the turntable 24, the fixed column 25, the transverse movement assembly 3, the fixed assembly 4 and the microphone 5 to rotate synchronously, so as to realize neck rehabilitation training for patients with limited neck movement caused by neck injuries or long-term poor postures.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
