Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a touch device in an embodiment.

In the embodiment, the touch device 10 is connected to the controlled device 20, and the touch device 10 can be applied to a hand exoskeleton device. The hand exoskeleton device can be a hand motion capture device with one or more functions of force feedback, tactile feedback and temperature feedback, and can be used for robot control, mechanical control, games and the like.

In the present embodiment, the touch device 10 includes a power source 100, a touch device 200, a control circuit 300, and a switch circuit 400.

The touch device 200 is configured to receive a touch signal of a user.

The control circuit 300 is respectively connected to the power supply and the touch device, and configured to obtain touch information corresponding to the touch signal, and output a corresponding action signal according to the touch information, where the action signal includes at least one of a start signal, a shutdown signal, and a restart signal.

The switching circuit 400 is connected to the power supply 100, the control circuit 300, and the controlled device 20, and controls the controlled device 20 to be powered on, powered off, or restarted according to the corresponding operation signal.

In the present embodiment, the power supply 100 supplies power to other units of the touch device; but are not limited to, a dry cell, a battery, and the like.

In this embodiment, the touch device 200 may sense and receive a touch signal of a user, where the touch signal is a signal generated by the touch device 200 after the user directly contacts or indirectly contacts the touch device 200. Therefore, the touch assembly 200 acquires the touch signal in a touch manner, so that the sensitivity is high, the failure is not easy to occur, and the reliability and the service life of the device are improved; and the device can be prevented from being provided with a groove by a touch control mode, so that the touch control device has good waterproof and dustproof performances.

In one embodiment, the touch signal can be generated by a single click, a double click, a touch duration or a touch trajectory of the touch component 200 by the user. The touch signal may be a digital signal string or a graphic signal. The digital signal string may be a continuous signal or an intermittent signal, such as a signal generated when a user presses the touch assembly 200 for a long time, or a signal generated when a user touches for a preset time interval. The graphic signal may be a signal generated according to a user touch trajectory, for example, if the trajectory touched by the user on the touch assembly 200 is "w", the image signal is "w".

In one embodiment, the touch device 200 may be a capacitive touch device, which generates a touch signal by generating a capacitance change through a user touch. For example, when the controlled device 20 is in the standby state, the capacitor touch component has a certain capacitance; when a human body touches the capacitance touch component, the capacitance touch component and the human body form a new capacitance, so that the capacitance changes, and a capacitance change signal, namely a touch signal, is generated. For example, when the controlled device 20 is in an operating state, once a human body touches the capacitive touch element, the capacitance changes, and a capacitance change signal is generated.

In one embodiment, the capacitive touch device is a capacitive switch, and the capacitive switch includes two plates, so that when the control circuit 300 is powered on, a potential difference exists between the two plates of the capacitive switch, one plate of the capacitive switch is electrically connected to the control circuit 300, and the other plate of the capacitive switch may be grounded. When a human body touches the capacitance switch, the human body is equivalent to a third polar plate, and after the human body and the two polar plates of the capacitance switch are combined into a new capacitor, the capacitance between the polar plates is changed to form a capacitance change signal.

In this embodiment, the control circuit 300 can obtain the touch information corresponding to the touch signal and output the corresponding action signal according to the touch information. The touch information includes an object type and an instruction type. The object type is a specific type of the controlled device, for example, the controlled device is an exoskeleton main body device; or the controlled device is only a part of the main body device, such as a feedback device.

In an embodiment, the instruction type includes one or more of a turn-on instruction, a turn-off instruction and a restart instruction, and correspondingly, the action signal includes one or more of a turn-on signal, a turn-off signal and a restart signal, so as to correspondingly implement power-on, power-off or restart of the controlled device.

In another embodiment, when the controlled device 20 is powered on, the instruction type may further include an operation instruction, and accordingly, the action signal may further include an operation signal; the controlled device 20 is connected to the control circuit 300, and the controlled device 20 executes corresponding operation actions according to the operation signal, so that the touch device not only has the functions of turning on, turning off and restarting, but also can control the operation actions of the controlled device 20, has multiple functions, and improves the function utilization rate. The motion signal may include only the operation signal. The operation instruction comprises an operation type and an output size, for example, the operation type can be one or more of force feedback, tactile feedback and temperature feedback, and the output size corresponds to the output value of the feedback.

In an embodiment, a one-to-one correspondence table between the touch signals and the touch information is preset in the control circuit 300, and when the control circuit 300 receives the touch signals, the touch information corresponding to the touch signals is detected by looking up the correspondence table, so as to output corresponding action signals according to the touch information.

For example, if the control circuit 300 presets that the continuous signal with the duration of t corresponds to the operation command, when the control circuit 300 detects that the signal generated by the touch device 200 is the continuous signal with the duration of t, it determines that the touch signal is the operation command input by the user, and outputs the corresponding operation signal according to the operation command. If the control circuit 300 cannot detect the touch information corresponding to the touch signal, the current action is maintained, and no action signal is output. Furthermore, when the operation instruction has multiple operation types, different operation types corresponding to different times can be preset, and the type of the operation can be further determined by detecting the length of the time. For example, when the duration t is less than 2s, the operation command is a force feedback command; and when the duration t is greater than or equal to 2s, the operation command is a tactile feedback command.

For example, if the control circuit 300 presets the continuous signal with the duration of t as the turn-on command, when the control circuit 300 detects that the signal generated by the touch device 200 is the continuous signal with the duration of t, it determines that the touch signal is the turn-on command input by the user, and outputs the corresponding turn-on signal according to the turn-on command. If the control circuit 300 cannot detect the touch information corresponding to the touch signal, the current action is maintained, and no action signal is output.

For example, if the control circuit 300 presets that the image signal with the touch trajectory "w" is the on command, when the control circuit 300 detects that the signal generated by the touch device 200 is the image signal with the touch trajectory "w", it determines that the touch signal is the on command input by the user, and outputs the corresponding on signal according to the on command. If the control circuit 300 cannot detect the touch information corresponding to the touch signal, the current action is maintained, and no action signal is output.

In one embodiment, the control circuit 300 comprises a single chip, a power supply end of the single chip is connected with the power supply 100, an input end of the single chip is connected with the touch component 200, and an output end of the single chip is connected with the switch circuit 400; in another embodiment, the control end of the singlechip is connected with the controlled device. The singlechip detects touch information according to the touch signal and outputs a corresponding action signal according to the touch information. Optionally, the single chip microcomputer is model MSP430 manufactured by TI (Texas Instruments ), such as MSP430FR25x2 or MSP430FR 2633. The MSP430FR25x2 type single-chip microcomputer can be used in industrial environments influenced by electromagnetic interference, oil, water and grease, and is low in power consumption and high in reliability.

In this embodiment, the switch circuit 400 controls the controlled device 20 to be powered on, powered off, or restarted according to the corresponding action signal, or controls the controlled device 20 to perform the corresponding operation action. Specifically, when the control circuit 300 outputs one or more of a turn-on signal, a turn-off signal, a restart signal, and an operation signal, the switch circuit 400 controls the controlled device 20 to be powered on, powered off, restarted, or perform a corresponding operation action.

In one embodiment, the switching circuit 400 includes a processor coupled to the power supply 100 to operate using power provided by the power supply 100. When the processor receives one or more of the turn-on signal, the turn-off signal, the restart signal and the operation signal, the controlled device 20 is controlled to be powered on, powered off, restarted or perform corresponding operation actions.

In another embodiment, the switch circuit 400 includes a switch and a relay, and when the relay receives one or more of the on signal, the off signal and the restart signal, the on/off of the switch is controlled to control the controlled device 20 to be powered on, powered off and restarted. The operation of the controlled device 20 is directly controlled by the control circuit 300.

The touch device provided by the embodiment comprises a power supply, a touch component, a control circuit and a switch circuit, wherein the touch component receives a touch signal of a user, the control circuit detects touch information according to the touch signal and outputs a corresponding action signal according to the touch information, so that the switch circuit controls a controlled device to be powered on, powered off or restarted according to the corresponding action signal. The touch device realizes the electrification, the outage or the restart of a controlled device in a touch mode, has high sensitivity, is not easy to break down, and improves the reliability and the service life of the device; and can avoid slotting on the device and set up the button through the touch-control mode, therefore touch-control device has good waterproof, dustproof performance, can also promote pleasing to the eye degree.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a touch device in another embodiment.

On the basis of the above embodiments, the touch device further includes an indication component 500.

The indicating component 500 is connected to the control circuit 300 and configured to indicate the corresponding operating state of the controlled device 20 according to the action signal, so that a user can know the operating state of the controlled device 20 in real time.

In one embodiment, the indicator assembly 500 includes one or more of an indicator light, a player, and a vibrator. Referring to fig. 3, fig. 3 illustrates an example in which the indication assembly 500 includes an indication lamp 501, a player 502, and a vibrator 503.

The indicator lamp 501 is connected to the control circuit 300 and configured to perform a light change according to the action signal to indicate the operating state of the controlled device 20. In one embodiment, the light change includes one or more of a light brightness change, a light color change, and a light flicker frequency change. The indicator light can be set into an image with any shape according to actual needs.

The player 502 is connected to the control circuit 300, and configured to play corresponding sound information according to the action signal, and indicate the operating state of the controlled device 20. In one embodiment, the sound information of different working states is different, for example, the strength of the sound is different, the playing content of the sound is different, or the playing frequency of the sound is different.

And a vibrator 503 connected to the control circuit 300 and configured to vibrate with a corresponding amplitude according to the action signal to indicate the operating state of the controlled device 20.

For example, the starting process can be indicated by the combination of the brightness change of the lamp tube of the indicator light, the sound information and the vibration (taking the touch component 200 as a capacitive touch component as an example): when the controlled device 20 is in a standby state and a user touches the capacitance touch component, the control circuit 300 acquires the capacitance change signal and controls the indicator lamp 501 to emit darker light. During the process of the user continuously touching the capacitive touch component, the control circuit 300 controls the light emitted from the indicator lamp 501 to gradually turn on. When the controlled device 20 is turned on, the light of the indicator lamp 501 reaches the brightest and stable light. At this time, the control circuit 300 controls the player 502 and the vibrator 503 to operate. If the time length of the user continuously touching the capacitive touch element does not reach the time length required for turning on, the control circuit 300 controls the light emitted from the indicator lamp 501 to gradually dim after the user stops touching the capacitive touch element.

Similarly, when the controlled device 20 is turned on, and the user touches the capacitive touch component, the control circuit 300 obtains the capacitance change signal, and after the capacitive touch component is turned off, the control circuit 300 controls the indicator lamp 501 to gradually dim, and controls the player 502 and the vibrator 503 to operate. If the user does not touch the capacitive touch element for the required time period, the control circuit 300 does not control the operation of the indicator lamp 501, the player 502 and the vibrator 503.
