As used herein, the meaning of 'comprising' specifies a particular characteristic, region, integer, step, operation, element and/or component, and other specific characteristic, region, integer, step, operation, element, component, and/or group. It does not exclude the existence or addition of

Hereinafter, a power supply device for an electronic device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As an example of the present invention, although the present invention is described with an electronic device as a locking device for a door lock, it is obvious that the present invention is not limited to a power supply that supplies power as a locking device for a door lock.

First, referring to FIG. 1 , a power supply device for controlling power supply to the locking device 60 of the door lock according to this example will be described.

As shown in FIG. 1, the power supply of the locking device 60 of this example includes a battery 10, which is a power supply (eg, a basic power supply), a battery 10, and a remaining power switch connected to the locking device 60 ( 20), the output control unit 30 connected to the locking device 60, the self-generation unit 40, the self-generation unit 40, and a storage battery that is connected to the output control unit 30 and is a power supply (eg, Auxiliary power supply) (50) is provided.

The battery 10 is a power supply unit (eg, a basic power supply unit) for supplying power necessary for driving the lock device 60 of the door lock, which is an electronic device, and may be a primary battery.

The battery 10 may include a first battery unit 11 and a second battery unit 12 .

The remaining power switch unit 20 controls the connection state of the first battery unit 11 and the second battery unit 12 of the battery 10 to a connection state of a series or parallel type to control the corresponding power to the output control unit 30 ) or to the locking device 60 .

In this case, the remaining amount switch unit 20 may include a switch unit 21 for controlling the connection state of the plurality of battery units 11 and 12 .

In this example, the switch unit 21 has an input terminal connected to the battery 10 , and an input terminal to a first switch whose switching state is changed to control a series or parallel connection relationship and an output terminal of the first switch. is connected, the output terminal is connected to the locking device 60 and the output control unit 30, respectively, and the switching state is different depending on the series or parallel connection relationship of the battery 10, so that the input terminal is the locking device A second switch connected to one of the 60 and the output control unit 30 may be provided.

The switch unit 21 changes the operating state by the user's operation, so that the connection relation of the plurality of battery units 11 and 12 in series or parallel form and the connection relation to the output control unit 30 or the locking device 60 are changed. It is possible to control or automatically control the states of the first switch and the second switch according to the power state of each of the battery units 11 and 12 .

Accordingly, the remaining power switch unit 20 may directly transfer the power of the battery 10 to the locking device 60 or to the output control unit 30 according to the power state of the battery units 11 and 12 .

For example, when the power supply state of one battery unit 11 or 12 can sufficiently drive the locking device 60 , for example, an electrical signal output from one battery unit 11 or 12 ( That is, when the power supply) is equal to or greater than the set value, the remaining power switch unit 20 controls the first and second battery units 11 and 12 in parallel and the locking device 60 directly without going through the output control unit 30 . ) can be supplied with power.

However, when the power of one battery unit 11 or 12 cannot drive the locking device 60 , the remaining amount switch unit 20 controls the first and second battery units 11 and 12 in series. and power can be directly supplied to the locking device 60 without going through the output control unit 30 .

In addition, when the power of the battery 10 connected in series cannot drive the locking device 60 (that is, when the power output from the first and second battery units 11 and 12 connected in series is less than the set value), The remaining amount switch unit 20 transmits the power of the battery 10 connected in series to the output control unit 30 .

Accordingly, the output control unit 30 changes the state of power transmitted from the battery 10 to a state capable of driving the locking device 60 , and then supplies the power to the locking device 60 .

The output control unit 30 changes the residual power applied from the battery 10 or the storage battery 50 , that is, boosts or reduces the pressure, so that the residual power of the battery 10 or the capacitor 50 is driven by the locking device 60 . to be used as a power source.

The output control unit 30 increases the input power by using a passive element such as a resistor or a capacitor, or by changing an electrical connection relationship (eg, a series connection and a parallel connection) to output to the locking device 60 . can

The output control unit 30 compares the electric signal (ie, power) applied from the residual quantity switch unit 120 and the capacitor 50 , selects one, and then changes the state of the electric signal to power the locking device 60 . can be supplied as

At this time, when the electric signal output from the battery 10 is equal to or greater than the set value, the output control unit 30 may transmit the electric signal (ie, power) of the battery 10 to the locking device 60 .

In addition, when the electric signal output from the battery 10 is less than the set value 1 and the electric signal output from the storage battery 50 is equal to or greater than the set value 2, the output control unit 30 locks the power of the storage battery 50 . (60) can be passed.

In this case, the set value 1 and the set value 2 may be the same or different.

When the set value 1 and the set value 2 are different, the set value 1 may be greater than the set value 2.

In addition, when the electric signal output from the storage battery 50 is less than the second set value, the remaining power switch unit 20 outputs the remaining power of the battery 10 according to the operation of the switch unit 20 operated automatically or manually. It can be transmitted to the control unit 30 .

The self-generation unit 40 may generate power by generating power according to the operation of the door lock.

This self-generation unit 40 is a rotary self-generation method in which electricity is generated using the rotational operation of an automatic locking unit (eg, automatic locking latch) attached to the door lock, and vertical movement of the cover moving in the vertical direction to input a password A sliding-type self-generation method using a state of a leaf spring that changes according to an operation state, such as an operation, and a rotary self-generation method using a fidget ball method may be used.

When the self-generation unit 40 is a rotary self-generation device operated in a rotary self-generation method, for example, the self-generation unit 40 generates kinetic energy by the rotation of the self-locking unit rotating in clockwise and counterclockwise directions. It may include a rotator that converts energy, a rectifier that converts an alternating current generated by the rotator into a direct current, and a charger that charges the DC output from the rectifier and charges the storage battery 50 .

When the self-generation unit 40 is a sliding-type self-generation device operated in a sliding-type self-generation method, the self-generation unit 40 is, for example, a leaf spring that is displaced back and forth according to the vertical movement of the door lock cover, a leaf spring A bar magnet connected and sliding when the leaf spring is displaced, a coil installed outside the bar magnet to generate an induced current according to the movement of the bar magnet, and charging the induced current generated in the coil and storing electricity in the storage battery 50 A charging unit may be provided.

In addition, when the self-generating unit 40 is a fidget-ball self-generating device using a fidget-ball method, the self-generating unit 40 is a rotor that rotates according to the operation of the door lock, and is arranged to be spaced apart along the circumference of the rotor. It can operate using the fidget spinner principle by having a stator having a plurality of coils, a bearing connected to the rotor, and a rectifier.

An example of such a case in which the self-generation unit 40 is a rotary self-generation device is, as shown in FIG. 3 , a reed switch (RS), a power supply (eg, a battery) (B+), a bobbin or an iron core. It may include a wound coil (C1) and a magnet (M1). In this case, the positions and sizes of the magnet M1 and the coil C1 shown in FIG. 3 may be changed.

Just before the power of the power supply unit (B+) is completely discharged, the power supply unit (B+) outputs energy to the self-healing power of the power supply unit (B+) and then stops repeatedly.

Therefore, when the energy of the power supply unit (B+) flows using the characteristics of the power supply unit (B+), a magnetic field is formed in the magnet (M1), the magnet (M1) rotates and the current flows in the power unit (B+) and stops. The magnet M1 also repeatedly generates and disappears a magnetic field, so that the magnet M1 continues to rotate.

When the magnet M1 rotates in the coil C1, an electromotive force is generated and a current flows. At this time, if the magnet (M1) does not rotate, rotate the magnet (M1) with a small force so that the magnet (1) can continue to rotate.

Accordingly, electricity is generated by the current generated by the rotation of the magnet M1.

In this way, the power generated according to the operation of the door lock in which the opening and closing operation is made is applied to the storage battery 50 to charge the storage battery 50 .

The storage battery 50 may include a primary battery, a secondary battery, or a large-capacity capacitor (eg, a supercapacitor) capable of charging a large-capacity power source.

In addition, the capacitor 50 may include a rectifier for rectifying electricity generated by the operation of the self-generation unit 40 into stable electricity.

In this case, when the battery 10 is formed of a rechargeable secondary battery, the self-generation unit 40 may perform a charging operation of the battery 10 as well as the storage battery 50 .

The power supply of an electronic device having such a structure may be operated as follows.

In the initial state, the first switch of the residual quantity switch unit 20 controls the connection relationship between the first battery unit 11 and the second battery unit 12 in a series form, and the second switch is the remaining quantity switch unit 20 ) can be controlled to be connected to the locking device 60 .

Therefore, in order to drive the door lock, the remaining power switch unit 20 directly applies the power output from the battery 10 to the locking device 60 , so the power for unlocking the locking device 60 is the battery 10 . will be supplied from

However, when the first switch is driven, the connection relationship between the first battery unit 11 and the first battery unit 12 is changed to a series form, and the remaining amount switch unit 20 changes the connection state with the locking device 60 . The power of the battery 10 connected in series is directly transferred to the locking device 60 through the maintained second switch and supplied as driving power.

This operation is continued until the magnitude of the power output from the residual quantity switch unit 20 through a connection relationship of a series or parallel type is equal to or less than a set value.

However, when the magnitude of the output power falls below the set value due to the series-type connection relationship between the first and second battery units 11 and 12 , the second switch of the remaining amount switch unit 20 sets the output control unit 30 . ) and output to the output control unit 30 of the power of the battery 10 less than the set value.

For this reason, the output control unit 30 compares the value of the electrical signal (ie, power) output from the storage battery 50 and the remaining amount switch unit 230 and converts one of the electrical signals to the locking device 60 . will output

At this time, the output control unit 30 may change the electric signal having a larger magnitude among the electric signal applied from the residual quantity switch unit 20 and the electric signal applied from the storage battery 50 and output it to the locking device 60 .

In addition, the output control unit 30 compares the electric signal of the capacitor 50 with the electric signal of the residual quantity switch unit 20 using the set values 1 and 2 as already described, and processes one of the electric signals. After that, it can be output to the locking device 60 .

In this way, since the operation of the locking device 60 is performed not only by the battery 10 but also by the storage battery 50 , which is charged with electricity generated by the self-generation operation of the door lock, the remaining amount of the battery 10 is stably Even if it is not enough to drive the locking device 60 , the operation of the door lock is normally performed.

Due to this, the problem of normally unlocking the lock state of the door lock with insufficient power of the battery 10 is solved, and also, when the battery 10 is in an abnormal state due to non-use for a long time or due to a low temperature, the user can smoothly It unlocks the door lock.

As such, when the electric signal output to the storage battery 50 for supplying power required for the operation of the locking device 60 in place of the insufficient battery 10 is less than the set value and the remaining amount of the storage battery 50 is less than the set amount, output The adjusting unit 30 may process the electric signal applied from the remaining amount switch unit 20 again.

As such, when the setting value of the basic power supply unit [eg, battery 10] is set to be greater than the setting value of the auxiliary power supply unit [eg, storage battery 50], the amount of residual power of the primary power supply unit (ie, set value) Since the amount of power less than the amount of power) is greater than the amount of power remaining in the auxiliary power supply, the locking device 60 can be operated more stably according to the operation of the output control unit 30 using the remaining power of the main power supply. there will be

In this example, the size of the set value 1 and the set value 2 determines whether the locking device 60 can be operated normally only with the power normally applied from the battery 10 or the storage battery 50 without a separate voltage conversion operation or step-up operation. may be determined depending on whether

Therefore, in the state in which the electrical signals corresponding to the remaining power of the battery 10 and the storage battery 50 are less than the set value 1 and the set value 2, respectively, the power of the battery 10 or the storage battery 50 without a separate voltage conversion or step-up operation It may be in a state in which the locking state of the locking device 60 cannot be stably released.

Accordingly, when the remaining amount of the battery 10 falls below the set amount, the locking state of the locking device 60 is not released even when the user operates the locking device 60 .

In this case, the user operates the door lock handle or the protrusion to operate the remaining amount switch unit 20 so that the remaining amount switch unit 20 is connected to the output control unit 30 instead of being connected to the locking device 60 .

Accordingly, when the remaining power of the battery 10 is supplied to the input terminal, the output control unit 30 controls the applied voltage, that is, increases or decreases the power, and then outputs to the locking device 60 . The voltage controlled by the output control unit 30 is of a level capable of normally executing the currently unlocking operation of the locking device 60 .

For this reason, the locking device 60 stably operates by the voltage output from the output control unit 30 to perform the unlocking operation.

Next, a power supply apparatus for an electronic device according to another embodiment of the present invention will be described with reference to FIG. 2 .

As compared with FIG. 1, components having the same configuration and performing the same function are given the same reference numerals as in FIG. 1, and detailed description thereof is also omitted.

As shown in FIG. 2 , the power supply device for controlling the power supply to the locking device 60 of the door lock according to an example adds a power state determination unit 70 connected to the battery 10 and the capacitor 50 . can be provided with

The power state determination unit 70 compares an electrical signal for power (ie, residual power) of the battery 10 with an electrical signal for power (ie, residual power) of the storage battery 50, and according to the comparison result Power output to the locking device 60 may be selected from among the battery 10 and the storage battery 50 .

In this case, the power state determination unit 70 may further include a switching unit that transmits an electrical signal having a larger value among the battery 10 and the capacitor 50 to the locking device 60 .

Alternatively, when the electric signal output from the battery 10 is equal to or greater than the first set value, the power state determination unit 70 transmits the power of the battery 10 to the locking device 60 and the electricity output from the battery 10 . When the signal is less than the first set value and the electrical signal output from the storage battery 50 is equal to or greater than the second set value, the power of the storage battery 50 may be transmitted to the locking device 60 .

In this case, the first set value and the second set value may be the same or different.

When the first set value and the second set value are different, the first set value may be greater than the second set value.

Also, when the electrical signal output from the storage battery 50 is less than the second set value, the power state determination unit 70 may transmit the remaining power of the battery 10 to the output control unit 40 .

In another example, the power state determination unit 70 may be connected only to the battery 10 .

In this case, the power state determination unit 70 receives the electrical signal output from the battery 10 and compares it with a set value (eg, a first set value), and according to the comparison result, the switch unit of the remaining amount switch unit 20 It is possible to control the output state to the locking device 60 by outputting to (21).

For this reason, at least one of the operation state of the first switch and the operation state of the second switch are changed, so that the first and second battery units 11 and 12 are connected in a series or parallel form or the output control unit 30 ) or the connection state to the locking device 60 can be controlled.

In FIG. 2 , this power state determination unit 70 is located outside the remaining amount switch unit 20 and is composed of a separate component from the remaining amount switch unit 20 , but, unlike this, the remaining amount switch unit 20 is located inside the to form a part of the remaining amount switch unit 20 .

Next, with reference to FIGS. 4 and 5, a description will be given of a power supply device of a locking device according to another embodiment of the present invention.

In this example, as compared with FIGS. 1 and 2 , components having the same structure and performing the same function are given the same reference numerals as in FIGS. 1 and 2 , and detailed description thereof is also omitted.

When comparing FIG. 4 with FIG. 1 and FIG. 5 with FIG. 2 , the storage battery 50 in FIGS. 4 and 5 is connected to the locking device 60 instead of being connected to the application control unit 30 , respectively.

Therefore, in the case of FIGS. 4 and 5 , the power charged in the storage battery 50 by the operation of the self-generation unit 40 is directly used as the driving power of the locking device 60 .

For this reason, either the power of the battery 10 or the power of the storage battery 50 that is directly output to the locking device 60 according to the operation of the switch unit 20 is directly transferred to the driving power of the locking device 60 .

According to another embodiment, when the power supply unit of the door lock includes only one secondary battery (eg, storage battery 50) capable of being charged by the self-generation unit 40 instead of the primary battery, the remaining amount switch unit 20 is After comparing the electric signal applied from the storage battery 50, which is one power supply, with a set value, the operation of the second switch is controlled according to the comparison result to control the power supply to the locking device 60 when the electric signal is greater than or equal to the set value. and if the electric signal is less than the set value, the residual power of the storage battery 50 may be applied to the output control unit 30 .

As such, when the door lock is provided with only one power supply that can be charged, the first switch of the remaining amount switch unit 20 may be omitted.

The power supply device shown in FIGS. 1 and 2 may additionally include an emergency power supply unit capable of opening and closing the locking device 60 using, for example, a 1.5V battery.

Such an emergency power supply may constitute a part of the battery 10 or the storage battery 50 .

In the current locking device 60 such as a door lock, a terminal for a 9V battery is exposed to the outside. Therefore, when electricity is applied to this terminal exposed to the outside with an emergency shock device, the operation of the corresponding locking device 60 is not performed normally, and the locking device 60 is opened, thereby creating a risk of theft.

However, when the terminal exposed to the outside of the locking device 60 is removed and an emergency power supply is provided, if only one 1.5V battery is inserted from the outside, the operation of the remaining power switch unit 20 and the output control unit 30 is reduced. By this, the operation of the locking device 60 is performed even with a single 1.5V battery, so that the locking device 60 is normally opened and closed.

According to this example, when the power of the battery 50 as well as the battery 10 decreases below the set value, the locking device 60 is driven using the remaining amount of the basic power supply, so the user's convenience is further improved. is improved, and since the remaining power of the battery 10 is used more efficiently, the waste of the battery 10 is also reduced.

In addition, in case of an emergency in which the unlocking operation of the locking device 60 is not performed due to discharging of the battery 10, the power supply terminal exposed to the outside of the electronic device such as a door lock can be removed, so that the corresponding electronic The security of the device is further increased.

The technical features disclosed in each embodiment of the present invention are not limited only to the embodiment, and unless they are incompatible with each other, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

Above, embodiments of the power supply device of the present invention have been described.
