The description is not intended to limit the technical solutions of the present application, and the embodiments of the present invention and the technical features in the embodiments may be combined with each other under the condition of no conflict.

Example 1

Referring to FIG. 1 , this embodiment provides a grip force sensor for use with at least one physical therapy device, that is, one-to-many real-time control can be realized. The physical therapy device has a kinetic energy output module 42. The purpose of this embodiment is to design a grip strength sensor to provide a control signal to the physical therapy device, so that the physical therapy device can control the intensity of the output signal of the kinetic energy output module 42 according to the control signal.

1-3 , the grip force sensor of this embodiment includes a first body 1 and a first control circuit 2 disposed in the first body 1 .

The first body 1 includes a holding portion 10 that is used for holding and can be deformed by force when being held. The holding portion 10 is a substantially cylindrical structure slightly recessed from the upper and lower ends to the middle. The first body 1 can be designed in various shapes, as long as it can provide a grip portion 10 to apply grip force to the user.

Specifically, the surface of the grip portion 10 is provided with a pressure area. Referring to FIGS. 1 and 2 , the pressure area includes a thumb pressing area 101 and an index finger pressing area 102 . In this embodiment, the thumb pressing area 101 and the index finger pressing area 102 are symmetrically arranged (as shown in the figure, A and B are shown to exert force on the center and detect the pressure), which is a symmetrical force-bearing structure. When the part 10 is held, the directions of force applied to the thumb pressing area 101 and the index finger pressing area 102 are opposite. The symmetrical force-bearing structure is more suitable for grip strength detection, and it can be comfortably controlled whether using the tiger's mouth or the palm.

Referring to FIG. 3 , the first control circuit 2 includes a first power supply 26 , a first controller 21 , a pressure sensor 22 connected to the first controller 21 , and a first communication interface 23 , and a first communication interface 23 is installed inside the pressure zone 3 The pressure sensor 22 and the first controller 21 are configured to receive the sensing signal generated by the pressure sensor 22 and output a control signal corresponding to the strength of the sensing signal to the physiotherapist through the first communication interface 23 , so that the physical therapy device controls the intensity of the output signal of its kinetic energy output module 42 according to the intensity of the induction signal.

Wherein, the first communication interface 23 is a wired communication interface or a wireless communication interface. The wireless communication interface used in this embodiment, such as a Bluetooth module, a WiFi module, a ZigBee module, and the like.

Wherein, the first power source 26 may be an ordinary battery or a rechargeable battery, which is used to supply power to the entire grip force sensor.

Preferably, the first control circuit 2 further comprises: a first button 24 connected to the first controller 21 for activating the grip force sensor; and a first key 24 connected to the first controller 21 The indicator light 25 is used to indicate the working state of the grip force sensor.

For example, the user needs to press the first button 24 every time before using the grip sensor, that is, the first button 24 is a trigger signal, and the first controller 21 only activates the first button 24 when it receives the pressing signal of the first button 24 The pressure sensor 22 detects the pressure, and when the first button 24 is pressed again or a timer can be configured for a long time to realize that no sensing signal from the pressure sensor 22 is received, the pressure sensor 22 is disabled, which can reduce energy consumption and avoid unintentional pressing at ordinary times. Incorrect control caused by entering the pressure zone.

For another example, after the first button 24 is pressed, the first indicator light 25 is turned on, indicating that the grip force sensor is enabled. Similarly, the first indicator light 25 is turned off, indicating that the grip force sensor is disabled.

Further, a plurality of first indicator lights 25 can also be set, and a corresponding number of first indicator lights 25 can be lit according to the strength of the induction signal. When the grip strength sensor works independently, the user can do it through the light feedback through the feedback effect. Daily grip training, or just holding and playing can bring psychological stress relief.

Considering the influence of external conditions (temperature and humidity, etc.) on the sensor of pressure detection products, there is often a data offset phenomenon, that is, after repeated use or long-term placement of the grip force sensor, even if no external force is applied, there will be non-zero detection data output. To solve the problem, the first controller 21 includes two working modes of measurement and calibration, and calibration is performed in the calibration mode.

Due to the small size of the grip force sensor, if the calibration operation is performed through the built-in buttons, it is not easy to meet the requirement of no external force interference. That is, when the user holds the product, it is inevitable to touch the pressure sensing area, which affects the accuracy of the calibration operation. Therefore, this embodiment It is proposed to initiate calibration using a controlled physiotherapy device. Specifically, the first controller 21 is further configured to receive the calibration signal sent by the physiotherapy device through the first communication interface 23, and when receiving the calibration signal, enter the calibration mode and perform the calibration function, so The performing calibration function described above includes: acquiring the sensing signal generated by the pressure sensor 22 when the grip strength sensor is in a resting state, and saving the recorded sensing signal as an offset. In addition, if the offset obtained in the calibration mode is higher than the offset threshold, it is determined that the grip sensor is not stationary, the recorded offset can be discarded, and the offset can be obtained again.

The first controller 21 is also used to perform data compensation on the sensing signal measured in real time by using the newly saved offset in the measurement mode. The compensation here is to subtract the offset from the sensing signal measured in real time. quantity.

The beneficial effect of this embodiment is that pressure sensing is a continuous input technology, which can steplessly adjust the output characteristics of kinetic energy output products. Compared with continuous input technologies such as buttons, it is especially suitable for man-machine of kinetic energy output products. Interactive, easy to operate, easy to control the input accuracy, the force input corresponds to the force output, which is more in line with human cognitive habits, and is more convenient for users to learn to master and adapt to the operation, especially for the grip force induction, the input operation with the hand is more flexible.

It should be noted that the grip force sensor in this embodiment can be a general product, matching any product that is suitable for control by grip force sensing. The matching method is a standardized wireless communication protocol. Specifically, the wireless communication circuit part of the grip sensor and all compatible controlled products adopts the same communication scheme. In the onboard software part of the circuit board, its wireless data transmission control program Adopt unified data transmission standard.

The physiotherapy massager according to claim 5, characterized in that, the first controller (21) includes two working modes of measurement and calibration, and the first controller (21) is further configured to pass the first The communication interface (23) receives the calibration signal sent by the physical therapy device, and when receiving the calibration signal, enters a calibration mode and performs a calibration function;

The performing calibration function includes: acquiring the sensing signal generated by the pressure sensor (22) when the grip strength sensor is in a resting state, and saving the recorded sensing signal as an offset;

The first controller (21) is further configured to perform data compensation on the sensing signal measured in real time by using the newly saved offset in the measurement mode.
