Description

Technical Field

[0001] The utility model relates to the technical field of physical therapy medical equipment, in particular to a data glove with wireless communication. Background Art

[0002] Most of the rehabilitation pneumatic gloves on the market have a mirroring function. The healthy hand wears a data glove and then synchronously controls the pneumatic glove on the affected hand to achieve the purpose of hand rehabilitation, which is called the mirroring function. Some of the data gloves with the mirroring function use wired control. A simple button or switch is inserted or embedded in the glove, and connected to the host by wired connection. The healthy hand wears the data glove and performs simple grip and stretching movements to trigger the button or switch, and synchronizes gripping and stretching with the pneumatic glove to achieve the mirroring function.

[0003] However, in actual use, the mirroring function requires at least one pneumatic glove and a wired data glove to be connected to work properly, which inevitably leads to wire entanglement, wire pressing and wire pulling. If you want to achieve separate control of five fingers, you need to increase the number of switches or buttons to be embedded in the fingers, which will cause discomfort to the healthy hand and make some simple gestures difficult to complete.

[0025] See also Figures 1 to 5, showing a wireless communication data glove and its circuit provided by an embodiment of the utility model, comprising a glove body 12, the glove body 12 having a plurality of finger sleeves 13, the glove body 12 also having a slave MCU10 and a first Bluetooth chip 11; each finger sleeve 13 is provided with a film bending pressure sensor 30, the film bending pressure sensor 30 is connected to the slave MCU10 to transmit the bending and straightening state signal of the sensed finger to the slave MCU10; the first Bluetooth chip 11 is connected to the slave MCU10 to receive the signal sent by the slave MCU10 and transmit it to the host MCU20; the slave MCU10 has a plurality of signal pins MCU_AD, and the plurality of signal pins MCU_AD are respectively connected to the corresponding The film bending pressure sensor 30 in the finger sleeve 13 is connected; the film bending pressure sensor 30 includes a sensing body 31, a voltage dividing resistor R11, and a signal end. The sensing body 31 includes a sensitive part 35 and a signal transmission part 36. The resistance of the sensitive part 3535 changes when a force is applied to sense the bending and straightening state of the finger. The signal transmission part 36 is provided with a first pin and a second pin. The first pin of the signal transmission part 36 is connected in series to the power supply pin of the slave MCU10 through the voltage dividing resistor R11, and the second pin is grounded. The signal end is provided between the voltage dividing resistor R11 and the first pin. Each of the signal ends is connected to a corresponding signal pin in the slave MCU10 to provide a voltage signal sampled on each finger.

[0026] Specifically, Figure 3 and 4 As shown, the signal end and the signal pin are grounded via a filter capacitor, which plays a role in protecting the chip signal pin of the slave MCU10.

[0027] Specifically, the first Bluetooth chip 11 is also configured to communicate with the host MCU 20, for receiving command signals from the host MCU 20 and feeding them back to the slave MCU 10. Specifically, the host MCU 20 is connected to a second Bluetooth chip 22, and the second Bluetooth chip 22 is wirelessly connected to the first Bluetooth chip 11.

[0028] In specific applications, the host MCU20 sends wired transmission to the serial port pin of the second Bluetooth chip 22 through the serial port. After receiving the instruction, it transmits the wireless Bluetooth transmission signal to the Bluetooth antenna of the first Bluetooth chip 11 of the data glove. The first Bluetooth chip 11 on the data glove sends the received wireless Bluetooth transmission signal through the serial port to the slave MCU10 of the data glove. Similarly, the data host MCU20 also receives the information sent on the data glove in this way to realize data and instruction interaction.

[0029] In some specific implementation schemes, the first Bluetooth chip 11 has pin 1, pin 2, pin 3, pin 4, pin 5, pin 6, pin 7, pin 8, pin 9, and pin 10. Among them, pin 1 is the chip sleep function, low level is effective, and a pull-up resistor is built in. Pin 2 is the power supply pin of the Bluetooth chip 11 and is externally connected to the decoupling capacitor C11; pin 3 is the power ground pin; pins 4 and 5 are connected to the passive crystal oscillator Y2 to provide a clock for the Bluetooth chip 11; pin 6 is connected to the Bluetooth antenna for RF radio frequency signal input and output.

[0030] In some preferred embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the glove body 12 has a palm sleeve body 15, and a plurality of finger sleeves 13 extend from the palm sleeve body 15. The slave MCU 10 is arranged on the palm sleeve body 15 and connected to each film bending pressure sensor 30 through a wire. Specifically, the sensitive part 35 of each film bending pressure sensor 30 is in the shape of a sheet or a strip, and the length of each sensitive part 35 is equal to or slightly less than the length of the corresponding finger sleeve 13, and the signal transmission part 36 is located at the root of the finger sleeve 13. The size of the film bending pressure sensor 30 is just embedded in each finger sleeve 13 of the glove body 12 and fits the finger perfectly, making the sensing more accurate, and the good flexibility makes it more comfortable for healthy hands to wear the data gloves, and does not hinder the completion of each finger movement at all.

[0031] Specifically, the connection circuit of the bending pressure sensor 30 is as follows: Figure 4As shown, the circuit structures of the bending pressure sensors 30 are basically the same, except that the signal ends are respectively connected to the corresponding signal pins MCU_AD0, MCU_AD1, MCU_AD2, MCU_AD3, and MCU_AD4 in the slave MCU10. Take the bending pressure sensor 30 in any finger body 12 as an example. P1 is the two pins of the bending pressure sensor, namely the 1st pin and the 2nd pin, which are non-polar. The resistor R1 and the internal resistance of the sensor are used for voltage division. The voltage collected by MCU_AD0 (or 1 / 2 / 3 / 4) is filtered by the capacitor C3 to filter out the redundant clutter signals and perform voltage buffering. The final voltage value is then connected to the MCU_AD0 pin of the slave MCU10 of the data glove through a wire. The pin is required to have an ADC function, that is, a pin for realizing digital-to-analog conversion; because the final voltage value is an analog signal, it is necessary to convert the analog signal into a digital signal through the ADC function of the pin of the slave MCU10 itself, so that the MCU itself can better judge the change of the sensor. When the slave MCU10 on the data glove reads the sensor changes, the changed data is transmitted to the Bluetooth chip 11 through the serial port by the slave MCU10 on the data glove in real time, and the Bluetooth chip 11 converts it into a Bluetooth wireless signal and transmits it to the host MCU20, thereby realizing the wireless data glove function.

[0032] In other embodiments, the voltage-dividing resistor R11, the signal terminal, and the capacitor in each film bending pressure sensor 30 are integrated on the same circuit board where the slave MCU 10 is located. Specifically, the slave MCU 10 and the Bluetooth chip are integrated on a circuit board, and the film bending pressure sensor 30, the slave MCU 10, the Bluetooth chip, and the connection lines are all arranged on the inner side of the glove body 12. Figure 2 As shown, a box body 16 is provided inside the palm sleeve body 15. Except for the film bending pressure sensor 30 and the wire, other components are installed in the box body 16. The box body 16 is also provided with an indicator light 18 and a switch 19 to facilitate switch operation and display of the working status.

[0033] Preferably, the model of the slave MCU10 is LPC11114FBD48, the model of the first Bluetooth chip 11 is C1H9141K, the host MCU20 and the slave MCU10 use the same chip, and the first Bluetooth chip 11 and the second Bluetooth chip use the same chip. The wireless communication data glove is used on a healthy hand, and a pneumatic rehabilitation device is connected to the affected hand. The host MCU20 is further connected to the pneumatic rehabilitation device on the affected hand wirelessly or by wire to send a manual operation signal corresponding to the bending and straightening state signal. When the five fingers of the healthy hand are each in a bent or stretched state, the gesture is identified and then the synchronous gesture of the affected hand is realized through wireless communication, so as to achieve the purpose of treatment and rehabilitation of the affected hand.

[0034] It should be noted that the present invention is not limited to the above-mentioned embodiments. According to the creative spirit of the present invention, those skilled in the art may also make other changes. These changes made according to the creative spirit of the present invention should be included in the scope of protection required by the present invention.
