The invention provides an intelligent finger dividing system which comprises a finger dividing plate 1 and finger dividing blocks 2 arranged on the finger dividing plate 1, wherein the finger dividing blocks 2 are connected with a driving device used for driving the finger dividing blocks 2 to move so as to adjust the distance between the adjacent finger dividing blocks 2, the intelligent finger dividing system also comprises a controller connected with the driving device through signals, two sides of the finger dividing blocks 2, which are in contact with fingers, are respectively provided with a first pressure sensor 21 connected with the controller through signals, the controller is also connected with an input device used for inputting preset pressure through signals, and when the pressure value detected by the first pressure sensor 21 is larger than or equal to the preset pressure, the controller controls the driving device to stop running.

The driving device is used for driving the finger dividing blocks 2 to move so as to adjust the distance between the adjacent finger dividing blocks 2 and adjust the contact pressure between the finger dividing blocks 2 and the fingers, and specifically, the driving device can drive the finger dividing blocks 2 to move along the length direction of the fingers, so that the contact pressure between the finger dividing blocks 2 and the fingers can be adjusted by adjusting the positions of finger gaps where the finger dividing blocks 2 are located. Considering that one finger plate 1 generally has five finger blocks 2, specifically, each finger block 2 can be separately connected with a driving device, so that the five driving devices respectively and independently drive the five finger blocks 2 to move, thus realizing the independent adjustment of the five finger blocks 2, and being applicable to palms of different sizes and fingers of different thicknesses, and meeting the requirement of finger rehabilitation training to the maximum extent.

The controller is in signal connection with the driving device to control the driving device through the controller, so as to further realize adjustment of front and back movement of the split finger block 2, the two sides of the split finger block 2 are respectively provided with a first pressure sensor 21 in signal connection with the controller, so that the contact pressure between the split finger block 2 and the finger is detected through the first pressure sensor 21, and the detected pressure value is transmitted to the controller, the controller is connected with an input device, the input device is used for inputting preset pressure, the preset pressure is the preset optimal contact pressure between the split finger block 2 and the finger, the contact pressure between the split finger block 2 and the finger can be continuously changed in the process that the driving device drives the split finger block 2 to move, when the contact pressure between the split finger block 2 and the finger is larger than or equal to the preset pressure, the pressure value between the split finger block 2 and the finger reaches the optimal contact pressure, therefore, the controller controls the driving device to stop running so as to realize effective rehabilitation training.

The intelligent finger dividing system provided by the invention has the advantages that the finger dividing blocks 2 are movably arranged on the finger dividing plate 1, the finger dividing blocks 2 are connected with the driving device, the driving device is controlled by the controller to adjust the positions of the finger dividing blocks 2, so that the distance between the adjacent finger dividing blocks 2 is adjusted, the use requirements of different patients are met, the application range is improved, the first pressure sensor 21 for detecting the contact pressure between the finger dividing blocks 2 and fingers is arranged on the finger dividing blocks 2, the first pressure sensor 21 is in signal connection with the controller, and the controller is provided with an input device for inputting preset pressure, so that the controller can control the driving device to automatically adjust the positions of the finger dividing blocks 2 according to the input preset pressure until the contact pressure between the finger dividing blocks 2 and the fingers is equal to or slightly greater than the preset pressure, the finger dividing automation is realized, and the contact pressure between the finger dividing blocks 2 and the fingers can be flexibly controlled, the training requirements of different patients are met, and the effect of finger rehabilitation training is obviously improved.

On the basis of the above embodiment, in consideration of the specific arrangement manner of the driving device, as a preferable mode, the driving device includes a motor and a screw rod 4 connected to the motor, a sliding block 3 is rotatably arranged on the screw rod 4, the finger-separating block 2 is arranged on the sliding block 3, and the controller controls the motor to rotate forward and backward to move the sliding block 3 forward and backward relative to the screw rod 4. In other words, in this embodiment, the motor drives the screw rod 4 to rotate, so that the sliding block 3 rotates relative to the screw rod 4 to drive the finger dividing block 2 to move, and the forward and backward movement of the finger dividing block 2 can be controlled by controlling the forward and backward rotation of the motor.

On the basis of the above embodiment, in view of the specific arrangement of the motor, it is preferable that the motor is a stepping motor 5. Specifically, the operation of each finger-dividing block 2 is independently controlled by 5 micro stepping motors 5, so that the position of each finger-dividing block 2 is independently adjusted according to the contact pressure of each finger-dividing block 2 and the finger, and the finger-dividing automation is realized. On the basis of the above embodiment, as a preferable mode, the controller includes a single chip microcomputer, and the single chip microcomputer is connected with a driving power supply for generating a pulse signal.

In other words, in this embodiment, the single chip microcomputer is used to generate a stable pulse signal to control the operation of the stepping motor 5, so that the stepping motor 5 drives the screw rod to rotate, and further the sliding drives the finger-separating block 2 to move forward or backward on the fixed guide rail, thereby meeting the automation of the finger-separating function. The single chip microcomputer can also receive signals detected by the first pressure sensors 21 on the two sides of the finger-separating block 2 so as to detect finger-separating force in real time, and thus, a feedback signal of finger-separating pressure is provided for the stepping motor 5 to advance. The singlechip timer is used for generating a pulse control signal with variable duty ratio, and the pulse control signal passes through the motor driving circuit and then drives the stepping motor 5 to realize forward rotation and reverse rotation, so that the requirement of automatic operation of the finger segmentation block 2 is met. Specifically, the method comprises the following steps. The motor is controlled to rotate forwards or backwards by applying high and low voltages to the terminals of the motor.

On the basis of any of the above embodiments, considering that if the preset pressure is set to be too large, when the finger dividing block 2 contacts the finger slit, the contact pressure of the finger dividing block 2 and the finger is still smaller than the preset pressure, in this case, the driving device will continue to drive the finger dividing block 2 to move, so that the finger may be damaged, in order to avoid the above problems, preferably, the end part of the finger dividing block 2 used for contacting the finger slit is provided with the second pressure sensor 22 connected to the controller through a signal, and when the pressure detected by the second pressure sensor 22 is greater than zero, the controller controls the driving device to stop operating.

It should be noted that the preset pressure should be adjusted according to different needs of the patient, for example, the position of the finger-separating block 2 can be adjusted manually at the beginning to determine the proper contact pressure between the finger-separating block 2 and the finger, and then the proper preset can be directly input according to experience, so as to adjust the finger-separating block 2 to the proper position through the controller, thereby realizing the automation of finger separation.

On the basis of the above embodiment, in view of the specific manner of inputting the preset pressure, as a preferable mode, the input device includes a display touch screen signal-connected to the controller for inputting the preset pressure, and the display touch screen is further configured to display the pressure values detected by the first pressure sensor 21 and the second pressure sensor 22.

Specifically, the display control interface of the display touch screen can independently set the preset pressure of each finger-separating block 2, so that the automation of the finger-separating function and the datamation of finger-separating force are realized. The display touch screen can select an OLED screen, an LCD screen, a touch screen and the like according to needs. The forward button and the backward button can be a physical button or a knob button on the display touch screen, and can also be a virtual button on the display touch screen.
