DETAILED DESCRIPTION
[0040] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0041] As mentioned in the background technology, a hand rehabilitation training case is often used in conjunction with rehabilitation training gloves, and is used as a power source and a power source for air to flow to or out of the rehabilitation training gloves. However, during the hand rehabilitation training, abnormal situations may occur. Therefore, when abnormal situations occur during hand rehabilitation training, how to cut off the circuit in time becomes a technical problem that needs to be solved urgently by those skilled in the art.
[0042] To solve the above problems, refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a chassis for hand rehabilitation training, including a box body 110, a power supply unit 120, a power unit and a circuit breaker unit 140. A accommodating cavity is formed inside the box body 110. The power supply unit 120 is installed in the accommodating cavity. The power unit is installed in the accommodating cavity. The circuit breaker unit 140 is installed in the accommodating cavity. The short-circuit unit includes a first connector 141 and a second connector 142. The first connector 141 is adapted to the second connector 142. The first connector 141 is connected to the power unit through a wire. The second connector 142 is connected to the power supply unit 120 through a wire. The second connector 142 can move toward or away from the first connector 141 to dock with or detach from the first connector 141, thereby electrically connecting or disconnecting the power supply unit 120 from the power unit. After the second connector 142 and the first connector 141 dock with each other, the power supply unit 120 supplies electric energy to the power unit, and the power unit and the rehabilitation training gloves are converted from an idle state to a working state. After the second connector 142 is disconnected from the first connector 141, the connection circuit between the power supply unit 120 and the power unit is cut off, and the power unit and the rehabilitation training gloves are converted from the working state to the idle state. In this way, when an abnormal situation occurs in the rehabilitation training gloves, the circuit can be cut off in time through the circuit breaker unit 140 to stop the power unit and the rehabilitation training gloves in an emergency. When the hand rehabilitation training chassis itself has abnormal phenomena such as overheating, the circuit can also be cut off in time through the circuit breaker unit 140 to stop the power unit in an emergency.
[0043] Specifically, in the exemplary embodiment, the circuit breaker unit 140 further includes a fixed seat 143, a movable seat 144 and a base 145. A first connector 141 is mounted on the fixed seat 143. A second connector 142 is mounted on the movable seat 144. The movable seat 144 can move toward or away from the fixed seat 143 to drive the second connector 142 to move toward or away from the first connector 141. The fixed seat 143 is fixed to the top of one end of the base 145, and a guide rail 1451 is provided on the top surface. The length direction of the guide rail 1451 is the same as the length direction of the base 145. The bottom of the movable seat 144 is slidably connected to the guide rail 1451 or slidably connected to the guide rail 1451 through a slider. The guide rail 1451 can guide the directional movement of the movable seat 144, and at the same time, can effectively improve the smoothness of the movement of the movable seat 144.
[0044] In some of the applications, the movement of the moving seat 144 is manually driven, and the maintenance and use cost is low.
[0045] In other applications, the circuit breaker unit 140 further includes a linear drive. The output shaft of the linear drive is connected to the movable seat 144, and is used to drive the movable seat 144 to move toward or away from the fixed seat 143 along the guide rail 1451. Compared with the human-driven method, the power-on and power-off efficiency is higher.
[0046] In some other applications, the circuit breaker unit 140 further includes a rotary driver 146. The output shaft of the rotary driver 146 is fixedly connected to one end of a screw rod 147. The movable seat 144 is connected to the screw rod 147 via a screw nut. The rotary driver 146 can drive the screw rod 147 to rotate, thereby driving the screw nut and the movable seat 144 to move along the guide rail 1451, so that the movable seat 144 moves toward or away from the fixed seat 143 along the guide rail 1451. Compared with the human-powered driving method, the power-on and power-off efficiency is higher.
[0047] Preferably, the linear drive can be a servo electric cylinder, which has higher control accuracy. The linear drive can also be an electric push rod, which can control the thrust and speed by adjusting the pitch, and can achieve very precise positioning and motion control. It does not require the use of liquid or gas and other working fluids during operation, so there will be no problem of hydraulic oil or gas leakage polluting the working environment, and the environmental protection performance is better. At the same time, it is easy to install and has low maintenance costs. Of course, the linear drive can also be a hydraulic cylinder or a pneumatic cylinder, which has a relatively stable power output, a faster action, strong reliability, a simple structure, and a low maintenance cost.
[0048] Preferably, the rotary driver 146 can be a servo motor with high control accuracy. Of course, the rotary driver 146 can also be a stepper motor.
[0049] Specifically, in the exemplary embodiment, a first main control board 131 and a temperature detection sensor 150 are also included. The temperature detection sensor 150 is installed in the accommodating chamber and is electrically connected to the first main control board 131. The temperature detection sensor 150 can detect the temperature in the accommodating chamber and send the detected temperature signal to the first main control board 131. The first main control board 131 is electrically connected to the power supply unit 120 and the linear drive / rotational drive 146 respectively. The power supply unit 120 supplies power to the first main control board 131. The first main control board 131 can control the linear drive / rotational drive 146 to work. The power unit includes an air pump 132 and a second main control board 133. The second main control board 133 is electrically connected to the air pump 132 and the first connector 141 respectively. The second main control board 133 can control whether the air pump 132 is working. The air pump 132 is used as a power source for air to flow to or out of the rehabilitation training gloves. After receiving the temperature signal detected by the temperature detection sensor 150, the first main control board 131 determines whether the temperature value is greater than 50°C. When the temperature is greater than 50°C, the first main control board 131 controls the linear driver / rotation driver 146 to work, so that the movable seat 144 moves along the guide rail 1451 away from the fixed seat 143, and then the second connector 142 is separated from the first connector 141, so that the power supply unit 120 is disconnected from the second main control board 133, and the second main control board 133 and the air pump 132 stop working.
[0050] Specifically, in the exemplary embodiment, the hand rehabilitation training case further includes a first training glove interface and / or a second training glove interface 160 and / or a third training glove interface 170 and / or a touch screen 180 and / or a switch 191 and / or a fan 192. The first training glove interface is mounted on the case 110, electrically connected to the second main control board 133, and used to connect the electrical stimulation rehabilitation training gloves. The second training glove interface 160 is mounted on the case 110, connected to the outlet of the air pump 132 or connected to the outlet of the air pump 132 through the switch valve 134. The second training glove interface 160 is used to connect the pneumatic rehabilitation training gloves. The third training glove interface 170 is mounted on the case 110, connected to the outlet of the air pump 132 or connected to the outlet of the air pump 132 through the switch valve 134. The third training glove interface 170 is used to connect the mirror rehabilitation training gloves. The switch valve 134 is a solenoid valve, which is also electrically connected to the second main control board 133, and the second main control board 133 controls the opening and closing of the switch valve 134. The touch screen 180 is installed on one side of the box 110 and is electrically connected to the second main control board 133, so as to facilitate human-computer interaction. The switch 191 is installed on the top of the box 110 and is electrically connected to the first main control board 131, and is used to control whether the power supply unit 120 supplies power to the first main control board 131. The fan 192 is installed on the top of the box 110 and is electrically connected to the second main control board 133, and is used to assist the heat dissipation of the accommodating cavity to the outside. The second main control board 133 can control whether the fan 192 and the switch valve 134 are working.
[0051] It should be pointed out that the specific circuit connection structure, working principle and logic program executed during operation of the first main control board 131 and the linear driver / rotation driver 146, the first main control board 131 and the temperature detection sensor 150, and the first main control board 131 and the switch 191 are prior art and will not be described in detail here.

[0052] Specifically, in the exemplary embodiment, the first connector 141 is a male connector or a female connector of a plug-in terminal, and correspondingly, the second connector 142 is a female connector or a male connector of a plug-in terminal.
[0053] Specifically, in the exemplary embodiment, the power supply unit 120 can be a primary battery with low cost. The power supply unit 120 can also be a secondary battery that can be recycled. The box 110 is also equipped with a charging socket electrically connected to the secondary battery.
[0054] The utility model also provides a hand rehabilitation training device, including electrical stimulation rehabilitation training gloves, pneumatic rehabilitation training gloves, mirror rehabilitation training gloves and a hand rehabilitation training chassis provided by any of the above embodiments.
