[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The core of the present invention is to provide an intelligent finger separation system, which realizes the automation of finger separation and controls the finger separation stroke according to the quantifiable finger separation pressure feedback, thereby realizing gradual treatment and avoiding the damage caused by forced finger separation.

[0026] Please refer to Figures 1 to 5 , Figure 1 A three-dimensional schematic diagram of a specific embodiment of the intelligent finger separation system provided by the present invention; Figure 2 A schematic top view of a specific embodiment of the intelligent finger separation system provided by the present invention; Figure 3 It is a partial three-dimensional schematic diagram of a specific embodiment of the intelligent finger separation system provided by the present invention; Figure 4 A partial side view schematic diagram of a specific embodiment of the intelligent finger separation system provided by the present invention; Figure 5 It is a partial front view schematic diagram of a specific embodiment of the intelligent finger separation system provided by the present invention.

[0027] The intelligent finger-splitting system provided by the present invention comprises a finger-splitting plate 1 and a finger-splitting block 2 arranged on the finger-splitting plate 1, wherein the finger-splitting block 2 is connected to a driving device for driving the finger-splitting block 2 to move so as to adjust the distance between adjacent finger-splitting blocks 2, and further comprises a controller whose signal is connected to the driving device, and first pressure sensors 21 whose signals are connected to the controller are respectively provided on both sides of the finger-splitting block 2 in contact with the fingers, and an input device for inputting a preset pressure is also connected to the controller by signal, and when the pressure value detected by the first pressure sensor 21 is greater than or equal to the preset pressure, the controller controls the driving device to stop running.

[0028] The driving device is used to drive the finger blocks 2 to move, so as to adjust the distance between adjacent finger blocks 2, and adjust the contact pressure between the finger blocks 2 and the fingers. Specifically, the driving device can drive the finger blocks 2 to move along the length direction of the fingers, so as to adjust the contact pressure between the finger blocks 2 and the fingers by adjusting the position of the finger gap where the finger blocks 2 are located. Considering that there are generally five finger blocks 2 on a finger plate 1, specifically, a driving device can be connected to each finger block 2 separately, so that the five driving devices can independently drive the movement of the five finger blocks 2. In this way, the five finger blocks 2 can be independently adjusted, so that it can be suitable for palms of different sizes and fingers of different thicknesses, so as to meet the needs of finger rehabilitation training to the greatest extent.

[0029] The controller signal is connected to the driving device so as to control the driving device through the controller, thereby realizing the adjustment of the forward and backward movement of the finger block 2. First pressure sensors 21 connected to the controller by signal are respectively provided on both sides of the finger block 2, so as to detect the contact pressure between the finger block 2 and the finger through the first pressure sensor 21, and transmit the detected pressure value to the controller. An input device is connected to the controller, and the input device is used to input a preset pressure, which is the preset optimal contact pressure between the finger block 2 and the finger. In the process of the driving device driving the finger block 2 to move, the contact pressure between the finger block 2 and the finger will also change continuously. When the contact pressure between the finger block 2 and the finger is greater than or equal to the preset pressure, it means that the pressure value between the finger block 2 and the finger has reached the optimal contact pressure, so that the controller controls the driving device to stop running to realize effective rehabilitation training.

[0030] The intelligent finger separation system provided by the present invention movably sets the finger separation block 2 on the finger separation plate 1, and the finger separation block 2 is connected to the driving device, and the driving device is controlled by the controller to adjust the position of the finger separation block 2, thereby realizing the distance adjustment between adjacent finger separation blocks 2, so as to meet the use needs of different patients and improve the scope of application, and the finger separation block 2 is provided with a first pressure sensor 21 for detecting the contact pressure between the finger separation block 2 and the finger, and the first pressure sensor 21 is connected to the controller signal, and the controller is provided with an input device for inputting a preset pressure. Therefore, the controller can control the driving device to automatically adjust the position of the finger separation block 2 according to the input preset pressure until the contact pressure between the finger separation block 2 and the finger is equal to or slightly greater than the preset pressure, thereby realizing the automation of finger separation, and the contact pressure between the finger separation block 2 and the finger can be flexibly controlled to meet the training needs of different patients and significantly improve the effect of finger rehabilitation training.

[0031] On the basis of the above embodiments, considering the specific arrangement of the driving device, as a preferred embodiment, the driving device includes a motor and a screw rod 4 connected to the motor, a slider 3 is rotatably arranged on the screw rod 4, and the finger block 2 is arranged on the slider 3, and the controller controls the forward and reverse rotation of the motor to make the slider 3 move forward and backward relative to the screw rod 4. That is, in this embodiment, the motor drives the screw rod 4 to rotate, so that the slider 3 rotates relative to the screw rod 4, and then drives the finger block 2 to move, and the forward and backward movement of the finger block 2 can be controlled by controlling the forward and reverse rotation of the motor.

[0032] On the basis of the above embodiment, considering the specific setting of the motor, as a preferred embodiment, the motor is a stepping motor 5. Specifically, the operation of each finger block 2 is independently controlled by 5 micro-stepping motors 5, so that the position of each finger block 2 can be independently adjusted according to the contact pressure between each finger block 2 and the finger, thereby realizing the automation of finger division. On the basis of the above embodiment, as a preferred embodiment, the controller includes a single-chip microcomputer, and the single-chip microcomputer is connected to a driving power supply for generating a pulse signal.

[0033] That is, in this embodiment, a single-chip microcomputer is used to generate a stable pulse signal to control the operation of the stepper motor 5, so that the stepper motor 5 drives the lead screw to rotate, and then the sliding drives the finger block 2 to move forward or backward on the fixed guide rail, so as to meet the automation of the finger function. The single-chip microcomputer can also receive the signal detected by the first pressure sensor 21 on both sides of the finger block 2 to detect the finger force in real time, thereby providing a feedback signal of the finger pressure for the stepper motor 5 to move. The single-chip microcomputer timer is used to generate a pulse control signal with a variable duty cycle, which drives the stepper motor 5 to realize forward and reverse rotation after passing through the motor drive circuit, thereby meeting the demand for automatic operation of the finger block 2. Specifically. The motor is controlled to rotate forward or reverse by applying high and low voltages to the terminals of the motor.

[0034] On the basis of any of the above embodiments, if the preset pressure is too large, when the finger block 2 contacts the interdigital gap of the finger, the contact pressure between the finger block 2 and the finger is still less than the preset pressure. In this case, the drive device will continue to drive the finger block 2 to move, which may cause damage to the finger. To avoid the above problem, as a preferred embodiment, the end of the finger block 2 for contacting the interdigital gap of the finger is provided with a second pressure sensor 22 connected to the controller by a signal. When the pressure detected by the second pressure sensor 22 is greater than zero, the controller controls the drive device to stop running. That is, in this embodiment, when the contact pressure between the finger block 2 and the finger reaches the preset pressure or the front end of the finger block 2 has contacted the interdigital gap of the finger, the drive device stops running, thereby preventing the finger block 2 from damaging the finger and playing a full stroke limit role.

[0035] On the basis of the above embodiment, considering the specific setting mode of the controller, as a preferred embodiment, the controller includes a forward button and a backward button, the forward button is used to trigger the driving device to drive the finger block 2 to move forward, and the backward button is used to trigger the driving device to drive the finger block 2 to move backward. Specifically, the forward button and the backward button can correspond to the forward and reverse rotation of the motor respectively.

[0036] It should be pointed out that the size of the preset pressure should be adjusted according to the needs of different patients. For example, the position of the finger block 2 can be manually adjusted at the beginning to determine the appropriate contact pressure between the finger block 2 and the finger. After that, the appropriate preset can be directly input based on experience to adjust the finger block 2 to the appropriate position through the controller, thereby realizing the automation of finger separation.

[0037] On the basis of the above embodiments, considering the specific method of inputting the preset pressure, as a preference, the input device includes a display touch screen whose signal is connected to the controller to input the preset pressure, and the display touch screen is also used to display the pressure values ​​detected by the first pressure sensor 21 and the second pressure sensor 22.

[0038] Specifically, the display control interface of the display touch screen can independently set the preset pressure of each finger block 2, thereby realizing the automation of the finger function and the digitization of the finger force. The display touch screen can select an OLED screen, an LCD screen, a touch screen, etc. as needed. The forward button and the back button can be physical buttons or knob buttons on the display touch screen, or virtual buttons on the display touch screen.

[0039] On the basis of the above embodiments, taking into account the specific selection of the first pressure sensor 21 and the second pressure sensor 22, as a preferred embodiment, the first pressure sensor 21 and the second pressure sensor 22 are both thin film pressure sensors, which will not occupy too much volume while ensuring the accuracy and sensitivity of pressure detection.

[0040] The above is a detailed introduction to the intelligent finger-splitting system provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
