Description

[Technical Field]

[0001] The present invention relates to a control unit for an electric opening / closing section, and more particularly to a control unit for an electric opening / closing section for opening and closing an opening / closing operation by a motor using a remote controller. [Background technology]

[0002] Electric shutters are known that are electrically operated to open and close the entrances and exits of stores, homes, parking lots, etc. Electric shutters are operated by an electric motor to open and close the entrances and exits of stores, homes, parking lots, etc. Electric motors are generally connected to and driven by an AC power source on the building side.

[0003] Also known is a system that opens and closes shutters by driving a DC motor with a solar cell without using an AC power source, as disclosed in Patent Document 1, for example. In this example, a battery is charged by a solar cell, and the DC motor is driven by the charged battery. By using a solar cell and a DC motor, wiring to the building is not required. A control panel, receiver, and motor are housed inside a shutter case placed on top of the shutter, and a solar panel is installed on the outside of the shutter case. The control panel controls the drive of the motor and controls the opening and closing of the shutter. The receiver receives remote control signals from an external transmitter. The battery is not housed inside the shutter case, but rather in the middle of the guide rail, making it easy to insert and remove the battery. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 7-102866 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of an electric shutter that is configured with an integrated shutter case, as disclosed in the above-mentioned Patent Document 1, all components must be installed when the electric shutter is installed. In other words, it was difficult to convert an existing manual shutter into an electric shutter, or to convert an existing electric shutter that is equipped with an AC motor into a DC shutter using a solar panel. Furthermore, in the electric shutter disclosed in Patent Document 1, the battery is mounted on the guide rail, so even if an attempt was made to replace the entire AC shutter case with a DC device, it was necessary to install a separate fixture to mount the battery on the guide rail and to run wiring to the battery. This required replacing all components, which made installation difficult and costly.

[0006] Therefore, there has been a demand for the development of a device that can easily convert an existing manual opening / closing unit such as a shutter into an electric opening / closing unit, or an AC-powered electric opening / closing unit into a DC-powered electric opening / closing unit.

[0007] In view of the above circumstances, the present invention aims to provide an electric opening / closing section control unit that can easily convert an existing manual opening / closing section or an AC-powered electric opening / closing section into a DC electric opening / closing section. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object of the present invention, the electric opening / closing section control unit of the present invention comprises a control section to which a motor cable from the motor is connected and which controls the motor, a wireless receiving section connected to the control section and which receives wireless signals from a remote controller, a secondary battery for supplying power to the control section, the wireless receiving section, and the motor, a unit housing fixed to the periphery of the opening / closing section and which houses the control section, the wireless receiving section, and the secondary battery inside, and a solar panel fixed to the outer surface of the unit housing and which charges the secondary battery.

[0009] Furthermore, the device may be provided with a resin case that houses the control unit and the wireless receiving unit.

[0010] The resin case may be any case as long as it is placed on the upper side inside the unit housing.

[0011] In addition, the unit housing has a motor cable retraction hole for retracting the motor cable connected to the control unit into the inside of the unit housing, and the motor cable retraction hole may be positioned below the position of the resin case.

[0012] Furthermore, the unit housing may be configured so that the outer surface of the unit housing to which the solar panel is fixed has a predetermined inclination angle to increase the power generation efficiency of the solar panel.

[0013] In addition, the solar panel has a solar cable extending from the surface side that is fixed to the unit housing, and the unit housing has a solar cable pull-in hole on the outer surface of the unit housing to which the solar panel is fixed, for pulling the solar cable inside.

[0014] Furthermore, the solar cable lead-in hole may be located below the positions where the control unit and the wireless receiving unit are located.

[0015] The solar cable lead-in hole may also be provided in a recess that is recessed inward and upward from the horizontal.

[0016] Furthermore, the wireless receiving unit receives wireless signals from the remote controller using an antenna, and the antenna is arranged outside the unit housing, with the antenna cable being pulled into the interior through the solar cable pull-in hole and connected to the wireless receiving unit.

[0017] The wireless receiving section may receive a wireless signal from the remote controller by an antenna, and the antenna may be electrically coupled to a motor cable connected to the control section inside the unit housing. [Effects of the Invention]

[0018] The electric opening / closing section control unit of the present invention has the advantage that it can easily convert an existing manual opening / closing section or an AC-powered electric opening / closing section into a DC electric opening / closing section.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic front view of an electric opening / closing unit control unit of the present invention installed in an opening / closing unit. As shown in the figure, the electric opening / closing unit control unit 10 of the present invention is used to open and close an opening / closing unit 1. The opening / closing unit 1 is configured to be wound up and stored by a motor 2, for example. The opening / closing unit 1 can be any device that can be opened and closed, such as a shutter, blind, or curtain. The opening / closing unit 1 can be any existing device. In other words, the electric opening / closing unit control unit 10 of the present invention can be applied to a device that has already been installed. However, the present invention is not limited to this, and the opening / closing unit 1 can also be applied during installation.

[0021] The motor 2 can be any existing or future developed motor, such as a DC motor, AC motor, or stepping motor, as long as it can open and close the opening / closing unit 1 via some kind of circuit. If an existing electric opening / closing unit is equipped with a motor that is not compatible with the control unit 20, it can be replaced with a compatible motor. In the case of an opening / closing unit 1 that is configured to be manually wound and stored, the motor 2 can be retrofitted.

[0022] A remote controller 3 is used to operate the opening / closing unit 1 by the motor 2 to open or close it. That is, the opening / closing unit 1 may be any unit that can be opened or closed by the remote controller 3. The remote controller 3 may be provided with, for example, an open button and a close button and be capable of remotely transmitting opening / closing operation commands. The communication method of the remote controller 3 is not limited to a specific method and may be, for example, a radio wave method or an infrared method. The remote controller 3 may also be a so-called smart remote control that is connected to a network. Furthermore, the remote controller 3 may not only transmit opening / closing operation commands but also be capable of receiving signals from the electric opening / closing unit control unit 10. For example, the remote controller 3 may be configured to not only perform opening and closing operations but also to check the open / closed state of the opening / closing unit 1.

[0023] A shutter case that winds up and stores the opening / closing unit 1 and houses the motor 2 is appropriately disposed above the opening / closing unit 1. The electric opening / closing unit control unit 10 of the present invention may be installed, for example, on this shutter case. The electric opening / closing unit control unit 10 of the present invention and the motor 2 are connected by a motor cable 4. That is, only one motor cable 4 extends from the electric opening / closing unit control unit 10 of the present invention to the opening / closing unit 1 side.

[0024] Fig. 2 is a schematic perspective view for explaining the details of the electric opening / closing section control unit of the present invention. In the figure, the same reference numerals as in Fig. 1 represent the same components. As shown in Fig. 2, the electric opening / closing section control unit 10 of the present invention is mainly composed of a control unit 20, a wireless receiving unit 30, a secondary battery 40, a unit housing 50, and a solar panel 60.

[0025] The control unit 20 controls the motor 2. A motor cable 4 from the motor 2 is connected to the control unit 20. The control unit 20 may be any control unit capable of appropriately controlling, for example, the number of rotations, rotation speed, torque, etc. of the motor 2. The control unit 20 may also be designed appropriately in accordance with the control method of the electric opening / closing unit. The control unit 20 is not limited to a specific one, and any existing or future developed control unit can be applied as long as it can control the opening and closing of the motor 2. The control unit 20 may also be configured to appropriately control the charging of the secondary battery 40, which will be described later.

[0026] The wireless receiving unit 30 receives a wireless signal from the remote controller 3. The wireless receiving unit 30 is connected to the control unit 20. In the illustrated example, the wireless receiving unit 30 and the control unit 20 are shown as separate entities, but the present invention is not limited to this, and the control unit 20 may have a built-in wireless receiving function. The wireless receiving unit 30 has, for example, an antenna or an infrared receiving unit corresponding to the communication method of the remote controller 3. The wireless receiving unit 30 receives a wireless signal from the remote controller 3 and sends an opening / closing operation command to the control unit 20. The wireless receiving unit 30 may have not only a receiving function but also a transmitting function as needed. Specifically, by enabling two-way communication using the transmitting and receiving function, it is possible to have, for example, a function that allows checking the open / closed state of the opening / closing unit 1.

[0027] The secondary battery 40 is used to supply power to the control unit 20, the wireless receiving unit 30, and the motor 2. A cable 41 of the secondary battery 40 is connected to the control unit 20, and the control unit 20 is used to distribute power appropriately to the wireless receiving unit 30 and the motor 2. The secondary battery 40 is not particularly limited to a specific shape, capacity, voltage, etc., and any battery can be used as long as it can secure the power necessary to drive the control unit 20, the wireless receiving unit 30, and the motor 2.

[0028] The unit housing 50 accommodates the control unit 20, the wireless receiving unit 30, and the secondary battery 40. The unit housing 50 may be fixed to the periphery of the opening / closing unit 1. Specifically, since only the motor cable 4 is connected to the opening / closing unit 1, the unit housing 50 may be fixed near the outlet of the opening / closing unit 1 for the motor cable 4. The unit housing 50 may be fixed to the periphery of the opening / closing unit 1 using double-sided tape or the like. Since the unit housing 50 is installed outdoors, it may be made of a durable metal that has been appropriately waterproofed. Furthermore, to ensure stable fixation, it is preferable that the unit housing 50 has a horizontally elongated shape, as in the illustrated example. In the case of a long and slender unit housing 50, for example, a long and slender secondary battery 40 can also be comfortably accommodated if it is also elongated as in the illustrated example.

[0029] The solar panel 60 is used to charge the secondary battery 40. The solar panel 60 is fixed to the outer surface of the unit housing 50. The outer surface of the unit housing 50 may be configured to have a predetermined inclination angle, for example, to increase the power generation efficiency of the solar panel 60. For example, the outer surface of the unit housing 50 may be configured to have an inclination angle of 30 to 60 degrees so that the solar panel 60 faces the sky. The solar panel 60 may be fastened to the unit housing 50 with screws, but from the perspective of waterproofing, it is undesirable for the unit housing 50 to have screw holes. Therefore, the solar panel 60 is preferably fastened to the unit housing 50 with double-sided tape or the like.

[0030] In this way, the electric opening / closing section control unit 10 of the present invention is configured as a single integrated unit in which the control section 20, wireless receiving section 30, and secondary battery 40 are housed inside the unit housing 50, and the solar panel 60 is fixed to the outer surface of the unit housing 50. This makes installation on the opening / closing section 1 easy, and makes it possible to easily convert an existing manual opening / closing section or an AC-powered electric opening / closing section into a DC electric opening / closing section.

[0031] Next, a specific configuration of the electric opening / closing section control unit 10 of the present invention will be described with reference to Figure 3. Figure 3 is a schematic exploded perspective view for explaining the details of the electric opening / closing section control unit of the present invention. In the figure, parts with the same reference numerals as in Figure 2 represent the same objects. The electric opening / closing section control unit 10 of the present invention allows contents to be taken in and out from inside the unit housing 50 as shown, for example, during installation or maintenance. As shown in the figure, it is sufficient if a side cover 51 is provided on the side of the unit housing 50. This makes it possible to store a pre-charged secondary battery 40 during installation, or to replace an old secondary battery 40 with low capacity with a new one.

[0032] A resin case 70 may be provided inside the unit housing 50. The resin case 70 houses the control unit 20 and the wireless receiving unit 30. By covering the electrical circuitry, which is more susceptible to water intrusion, such as the control unit 20 and the wireless receiving unit 30, with the resin case 70, it is possible to reliably waterproof the unit housing 50 even if rainwater or the like infiltrates the interior of the unit housing 50. Of course, the control unit 20 and the wireless receiving unit 30 may be housed in individual cases. A metal case may be used instead of the resin case 70, but since the case houses electrical circuitry, such as the control unit 20 and the wireless receiving unit 30, a resin case is preferable from the standpoint of insulation.

[0033] Next, FIG. 4 is a schematic side view illustrating the side of the unit housing of the electric opening / closing unit control unit of the present invention. In the figure, parts with the same reference numerals as in FIG. 3 represent the same objects. In the illustrated example, the outer surface of the unit housing 50 is configured to have a predetermined inclination angle to increase the power generation efficiency of the solar panel 60. As shown in the figure, the resin case 70 that houses the control unit 20 and the wireless receiving unit 30 is located on the upper side inside the unit housing 50. This is to prevent the resin case 70 from remaining submerged in rainwater, which would accumulate on the lower side inside the unit housing 50, even if rainwater or the like were to enter the inside of the unit housing 50. This configuration further enhances the waterproof effect.

[0034] Furthermore, the unit housing 50 has a motor cable lead-in hole 52. Specifically, the motor cable lead-in hole 52 is provided in the side cover 51. The motor cable lead-in hole 52 is for leading the motor cable 4 connected to the control unit 20 into the inside of the unit housing 50. The motor cable lead-in hole 52 may be appropriately treated with a grommet or the like to prevent water from entering the inside of the unit housing 50. However, rainwater or the like may run down the motor cable 4 and enter the inside of the unit housing 50. Therefore, even if rainwater or the like does enter, the motor cable lead-in hole 52 may be located below the position of the resin case 70 that houses the control unit 20 and the wireless receiving unit 30 so that it does not get on the resin case 70. This configuration further enhances the waterproof effect.

[0035] Next, FIG. 5 is a schematic cross-sectional side view illustrating the outer surface of the unit housing to which the solar panel of the electric opening / closing unit control unit of the present invention is fixed. In the figure, parts with the same reference numerals as in FIG. 2 represent the same components. For the sake of explanation, the illustrated example shows the state before the solar panel 60 is fixed to the outer surface of the unit housing 50. As shown in the figure, the solar panel 60 has a solar cable 61. The solar cable 61 extends from the surface side that is fixed to the unit housing 50. In other words, the solar cable 61 extends from the back side of the solar panel 60. Electricity charged in the solar panel 60 can be sent to the control unit 20 via the solar cable 61. As shown in the figure, the unit housing 50 has a solar cable lead-in hole 53 on the outer surface of the unit housing 50 to which the solar panel 60 is fixed, for leading the solar cable 61 into the interior. In other words, the solar cable 61 is led from the back side of the solar panel 60 into the interior of the unit housing 50 through the solar cable lead-in hole 53. As a result, when the solar panel 60 is fixed to the unit housing 50, the solar cable lead-in hole 53 is not exposed to the outside. Therefore, it is possible to prevent rainwater and the like from entering the inside of the unit housing 50 through the solar cable lead-in hole 53.

[0036] Also, as shown in the figure, the solar cable entry hole 53 may be located below the positions of the electrical circuitry, such as the control unit 20 and the wireless receiving unit 30. This makes it possible to configure the system so that even if rainwater or the like seeps in through the solar cable entry hole 53, it will not get on the control unit 20 or the wireless receiving unit 30.

[0037] Furthermore, FIG. 6 is a schematic cross-sectional side view illustrating another example of the outer surface of the unit housing to which the solar panel of the electric opening / closing unit control unit of the present invention is fixed. In the figure, parts with the same reference numerals as in FIG. 2 represent the same components. As shown, a recess 54 may be provided on the outer surface of the unit housing 50 to which the solar panel 60 is fixed. The recess 54 is recessed upward and inward from the horizontal. The solar cable entry hole 53 may be provided at the bottom of the recess 54. With this configuration, even if rainwater or other water seeps into the recess 54, there is no risk of the rainwater or other water seeping into the unit housing 50 through the solar cable entry hole 53 because the recess 54 has an upward recessed shape. The location of the solar cable entry hole 53 is not particularly limited to the bottom of the recess 54; it may be provided, for example, at the top of the recess 54.

[0038] Next, details of the wireless receiving unit of the electric opening / closing section control unit of the present invention will be described with reference to FIG. 7. FIG. 7 is a schematic perspective view for explaining details of the wireless receiving unit of the electric opening / closing section control unit of the present invention. In the figure, parts with the same reference numerals as in FIG. 2 represent the same components. As shown in the figure, the wireless receiving unit 30 may receive a wireless signal from the remote controller 3 via the antenna 31. In order to receive the signal via the antenna 31, the antenna 31 must be disposed outside the unit housing 50. In the electric opening / closing section control unit 10 of the present invention, for example, as shown in the figure, the antenna 31 may be disposed outside the unit housing 50, and the cable of the antenna 31 may be configured to be drawn into the interior through the solar cable lead-in hole 53 and connected to the wireless receiving unit 30. In order to lead the cable of the antenna 31 to the solar cable lead-in hole 53, for example, a recessed groove extending downward from the solar cable lead-in hole 53 may be provided, allowing the cable to be passed through the back side of the solar panel 60. By extending the groove downward from the solar cable lead-in hole 53, it is possible to prevent rainwater and the like from running down the groove and entering the inside of the unit housing 50. As shown in the figure, the antenna 31 may be positioned along the bottom edge of the solar panel 60 as appropriate.

[0039] Furthermore, FIG. 8 is a schematic diagram for explaining the details of another example of the wireless receiver of the electric opening / closing unit control unit of the present invention. In the figure, parts with the same reference numerals as in FIG. 7 represent the same components. As shown in the figure, the antenna 31 connected to the wireless receiver 30 may be configured to be electrically coupled to the motor cable 4 connected to the control unit 20 inside the unit housing 50. That is, the antenna 31 may be configured to be electrically coupled to the motor cable 4 in the frequency band of the wireless signal from the remote controller 3, but electrically insulated from the motor cable 4 in the frequency band of the control signal to the motor cable 4. Specifically, the wireless receiver 30 may be configured to be electrically coupled to or insulated from the motor cable 4 depending on the frequency band by using, for example, an appropriate low-pass filter or band-pass filter. With this configuration, it is not necessary to directly extend the antenna 31 outside the unit housing 50; it is sufficient to extend only the motor cable 4 outside the unit housing 50.

[0040] The electric opening / closing section control unit of the present invention is not limited to the above-mentioned illustrated example, and it goes without saying that various modifications can be made within the scope of the gist of the present invention. [Explanation of symbols]
