Description

The present invention relates to a power saving device, and in particular, can be applied to an actuator of a portable energy device (portable power supply device), and can cut off power when equipment is not used for a predetermined time. The present invention relates to a power-saving device for an actuator that can ignore self-discharge of a possible power supply device and has a very high power-saving effect.

  FIG. 1 is a schematic diagram of a conventional portable power supply device, which mainly includes a power supply circuit, a switch circuit, a charging circuit, and a control circuit.

  There are three types of usage of the conventional portable power supply device.

  First, the user manually turns on the switch circuit, the power supply circuit supplies energy (current) to the control circuit, and when the power supply circuit energy (voltage) is insufficient, the charging circuit charges the power supply circuit. .

  Second, the switch circuit is always turned on, and it is not necessary for the user to manually turn on the switch circuit. The power circuit always supplies energy (current) to the control circuit, and the power circuit's energy (voltage) ) Is insufficient, the charging circuit charges the power supply circuit, and if the equipment does not work, the control circuit enters the standby mode, but even in this mode, the energy (electric power) is consumed in a small amount.

Third, the switch circuit is always turned on, and it is not necessary for the user to manually turn on the switch circuit. The power supply circuit always supplies energy (current) to the control circuit, and the power supply circuit energy (voltage) ) Is insufficient, the charging circuit charges the power supply circuit, and if the equipment does not work, the control circuit does not enter the standby mode, so a large amount of energy (electric power) is consumed.

The main object of the present invention is applicable to an actuator of a portable power supply device. When the equipment is not used for a predetermined time, the power can be cut off, and the self-discharge of the portable power supply device can be ignored. Another object of the present invention is to provide a power saving device for an actuator that has a very high power saving effect.

  The first invention of the present application made to achieve the above object includes a portable power source that supplies necessary power for the entire system, a charging circuit that charges the portable power source so as not to be excessively charged, and a control A control circuit that controls the operation of the facility mechanism by operating the system, a power supply start circuit that starts connection of the portable power source and the entire system, a control command is transferred to the control circuit, and a power saving function is detected and A gist of the invention is a power saving device for an actuator, comprising: a CPU circuit for starting, and a control switch for starting the power supply control circuit after being triggered by the power supply start circuit. Yes.

  The gist of the second invention of the present application is the actuator power saving device according to the first invention, wherein the portable power source is a storage battery.

  The gist of the third invention of the present application is the power saving device for an actuator according to the first invention, wherein the power supply control circuit includes a set of relays.

The gist of the fourth invention of the present application is the actuator power saving device according to the first invention, wherein the power supply starting circuit is a transistor, a photocoupler, or a relay.

The actuator power saving device according to the present invention has the following effects.
(B) Applicable to actuators of portable power supply units. When equipment is not used for a predetermined time, power can be cut off, self-discharge of portable power supply devices can be ignored, and power saving effect is extremely high high.

  (B) The power control circuit can be activated by a general control button. When the control button is released, the CPU circuit manages the power and the CPU circuit determines when to enter the power saving mode. Level applications (for example, storage of actuator positions or collection of hospital bed data) can be realized.

(C) Environmentally friendly.

  Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  First, FIG. 2 and FIG. 3 will be referred to. 2 and 3 are only examples given to illustrate the invention and are not intended to limit the claims of the invention.

  The actuator power-saving device according to the present invention includes a portable power source 1 (in this embodiment, a storage battery is taken as an example), a charging circuit 2, a control circuit 3, a power source activation circuit 4, a CPU circuit 5, and a control. Switch 6.

  The portable power source 1 supplies the necessary power for the entire system.

  The charging circuit 2 charges the portable power source 1 so as not to be excessively charged.

  The control circuit 3 controls the operation of the facility mechanism by operating a control system.

  The power supply activation circuit 4 activates the connection between the portable power supply 1 and the entire system.

  The CPU circuit 5 transmits a control command to the control circuit 3 to detect and activate a power saving function.

  The control switch 6 serves as a trigger for the power supply activation circuit 4 and activates the power supply control circuit 3 after the power activation circuit 4 is triggered.

  When the actuator power saving device according to the present invention operates, the storage battery 1, the charging circuit 2, and the power supply activation circuit 4 are connected. Therefore, even if the power supply starting circuit 4 does not operate, the charging circuit 2 still charges the storage battery 1.

  In addition, the control switch 6 can trigger the power supply start circuit 4 and the CPU circuit 5 separately. When the control switch 6 is pressed, the PNP transistor 7 is turned on, and then the NPN transistor When the relay 9 is also turned on and the relay 9 is also turned on, the power supply starting circuit 4 is started and the CPU circuit 5 starts to work.

  When the CPU circuit 5 receives the signal transferred from the control switch 6 and transfers the corresponding signal to the control circuit 3, the CPU circuit 5 starts to control the power supply activation circuit 4. At this time, even if the relay 9 is kept in a conducting state and the PNP transistor 7 is turned off by the control switch 6, the NPN transistor 8 is controlled by the CPU circuit 5, so that the relay 9 still keeps a conducting state. .

  Further, when the control switch 6 is released, the CPU circuit 5 still keeps the power activation circuit 4 in the conductive state. When it is time to enter the power saving mode, the CPU circuit 5 turns off the NPN transistor 8 and turns off the relay 9. At this time, the power supply to the CPU circuit 5 and the control circuit 3 becomes zero. Therefore, the power saving effect is extremely high.

  Thus, although the invention has been described with reference to specific examples, these are only for the purpose of illustrating embodiments and are not intended to limit the invention and have general knowledge in the art. Those skilled in the art may make changes, additions, or deletions to the embodiments disclosed herein without departing from the spirit and scope of the present invention.
