Description

Technical Field

[0001] This invention relates to the field of smart homes, and in particular to a remote control device for a traditional switch assembly. Background Technology

[0002] With the development of computer and internet technologies, humanity has entered the era of intelligence. The Internet of Things (IoT) connects every object to the network, making the interconnection of everything a defining characteristic of this era. The increasing sophistication of manufacturing has enabled intelligent products to be higher-performing, smaller, and more personalized. Various intelligent products, with their advantages of intelligence and convenience, are permeating all aspects of human life. Smart homes are intelligent products used in home life, providing residents with more comfortable living conditions. However, because smart homes require corresponding software and hardware support, there are certain application barriers. Furthermore, some home furnishings have a long lifespan, and their hardware cannot meet the needs of intelligent living; or some home furnishings cannot be replaced, thus preventing the enjoyment of the convenience brought by smart homes.

[0003] Switches that control lights or other items are installed after the house is renovated and are considered long-lasting hardware. If they are not designed with smart technology in mind, they can only be used manually, which is inconvenient, especially when the switch is far from the bed, door, or office space. Walking close to the switch to switch lights is very inconvenient and affects the user experience. While smart switches offer a better experience, they also have drawbacks such as higher price, greater difficulty in replacement, and incompatibility with the house design. Furthermore, some non-private residences, such as rental houses and dormitories, do not allow unauthorized modifications, resulting in hardware deficiencies in smart switch technology. Summary of the Invention

[0004] The purpose of this invention is to provide a remote control device for a traditional switch group, which can transform a traditional switch group into a remotely controllable switch group. Without affecting the original use, it can transmit commands through Bluetooth, infrared or WIFI and realize remote control of the switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conventional remote control device for a switch assembly includes a base, a bidirectional motor, a controller, a wireless receiver, a battery module, a rotating shaft, multiple simple clutches, multiple switch plates, and a protective cover. The bidirectional motor, controller, wireless receiver, and battery module are mounted on the base. The battery module supplies power to the entire device. The bidirectional motor is connected to the base via a height adjustment mechanism. The rotating shaft is connected to the bidirectional motor. Each switch plate is fixedly mounted on a switch, and each switch plate is fixedly connected to a simple clutch. The simple clutch can engage the rotating shaft when powered on and disengage from the rotating shaft when powered off. The protective cover is connected to the bidirectional motor. The protective cover contains multiple parallel power supply circuits, each power supply circuit supplying power to one simple clutch. The wireless receiver receives switch control commands. According to the switch control commands, the controller controls the corresponding power supply circuit to supply power to the simple clutch of the corresponding switch to engage the rotating shaft, and simultaneously controls the bidirectional motor to drive the rotating shaft to rotate, thereby rotating the switch plate to open or close the corresponding switch.

[0007] Furthermore, the rotating shaft is made of iron, and the simple clutch includes an annular bracket and multiple sets of electromagnets. The multiple sets of electromagnets are arranged around the rotating shaft, and the annular bracket is provided with multiple grooves to accommodate the electromagnets. Each set of electromagnets is connected to the bottom of the corresponding groove through a first spring. When the electromagnet is energized, it generates a magnetic force to attract the rotating shaft, and the first spring is stretched. When the electromagnet is de-energized, the first spring returns to its original state, causing the electromagnet to disengage from the rotating shaft.

[0008] Furthermore, an anti-slip head is provided at the end of the electromagnet facing the rotating shaft.

[0009] Furthermore, the rotating shaft is a non-ferrous rotating shaft, and the simple clutch includes a ring bracket, multiple sets of electromagnets, and multiple rubber sheets. The multiple sets of electromagnets are fixed on the ring bracket along the circumferential direction, and the multiple rubber sheets are arranged around the rotating shaft. One end of each rubber sheet is fixed on the ring bracket, and the other end is connected to a magnet. Each magnet corresponds to a set of electromagnets. When the electromagnet is not energized, the magnet is attracted to the iron core of the corresponding electromagnet. When the electromagnet is energized, it generates a magnetic force in the same direction as the magnet, causing the like poles of the magnets to repel each other and drive the rubber sheet to stick to the rotating shaft. When the electromagnet is de-energized, the magnet is attracted back to the electromagnet and detaches from the rotating shaft.

[0010] Furthermore, the power supply circuit in the protective cover is made of exposed conductive metal. The power supply circuit is electrically connected to the electromagnets in the annular bracket through contact points. The annular bracket has a shell on its outer side, which is fixedly connected to the protective cover. An opening slot is provided on the top of the shell, and the shell is also provided with adjustable openings of different numbers that communicate with the opening slot. The positions of the adjustable openings of different numbers correspond one-to-one with the positions of multiple power supply circuits in the protective cover. The contact point has a convex structure, including a circuit connection end at the top and a clutch connection end and a touch end at the left and right ends. The circuit connection end and the clutch connection end can conduct electricity. The touch end is an insulated end. The circuit connection end is accommodated in the opening slot and contacts the power supply circuit in the protective cover. The touch end passes through the adjustable opening and protrudes from the adjustable opening. The clutch connection end is connected to each electromagnet in the annular bracket through a wire. The position of the circuit connection end can be adjusted by moving the touch end to different numbered adjustable openings, so that the circuit connection end can be electrically connected to different power supply circuits in the protective cover.

[0011] Furthermore, the rotating shaft has a multi-section detachable structure.

[0012] Furthermore, the protective cover has a multi-segment detachable structure, and the power supply circuits of adjacent protective cover segments are electrically connected to each other through endpoint contact, so that the power supply circuit continues uninterrupted after the multiple protective cover segments are connected to each other.

[0013] Furthermore, the height adjustment mechanism includes a motor enclosure and a second spring. The motor enclosure is mounted on the base, and the bidirectional motor is located inside the motor enclosure. The bidirectional motor is connected to the base via the second spring. The motor enclosure is used to restrict the bidirectional motor to move up and down only along the height direction of the enclosure.

[0014] Furthermore, the height adjustment mechanism includes a motor enclosure and a motor baffle. The motor enclosure is mounted on the base, and the bidirectional motor is located inside the motor enclosure. The motor enclosure has multiple latching holes, and the bidirectional motor is connected to multiple sets of motor latches. The bidirectional motor and the motor enclosure are connected through motor latches and latching holes. The height of the bidirectional motor can be adjusted by adjusting the connection position of the motor latches and latching holes. The motor baffle is used to insert between the rear end of the bidirectional motor and the motor enclosure after the motor latches are connected to the latching holes to fix the bidirectional motor. When the motor baffle is pulled out, the bidirectional motor moves backward, causing the motor latches to disengage from the latching holes.

[0015] Furthermore, the outer ring of the annular bracket is provided with a roller, and the protective cover is connected to the annular bracket through the roller, and the roller can rotate freely inside the protective cover.

[0016] Furthermore, the aforementioned conventional switch group remote control device also includes several clips, each clip being used to be fixedly installed on a switch, and the bottom of the switch piece is provided with a slot for engaging with the clip.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are:

[0018] This invention enables remote control of switch groups to open or close without damaging the switches, utilizing transmission methods such as Bluetooth, infrared, and WIFI. The device is simple in design, relatively inexpensive compared to independent smart switches, easy to install, and will not damage the switches or walls. It can control multiple switch groups simultaneously. The rotating shaft and protective cover are detachable, allowing users to flexibly assemble or disassemble them according to the length of the switch group. The simple clutch is in the engaged state when no signal is received, without affecting manual switch operation. Users can choose to remotely or manually control the switches as needed.

[0029] The present invention will be further described below with reference to specific embodiments. These embodiments are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] like Figures 1 to 2 As shown, a conventional switch group remote control device includes a base 1, a bidirectional motor 2, a controller 3, a wireless receiver 4, a battery module 5, a rotating shaft 6, multiple simple clutches 7, multiple switch plates 8, and a protective cover 9.

[0031] The base 1 is positioned next to the conventional switch 11, such that the pivot 6 coincides with the central axis of the conventional switch 11. The base 1 can be attached to the wall next to the conventional switch 11 using glue or similar adhesive.

[0032] The bidirectional motor 2, controller 3, wireless receiver 4 and battery module 5 are all mounted on the base 1. The battery module 5 is used to power the entire device.

[0033] The bidirectional motor 2 is connected to the rotating shaft 6 and is used to drive the rotating shaft 6 to rotate clockwise or counterclockwise. The bidirectional motor 2 is also connected to the controller 3, and under the control of the controller 3, it can drive the rotating shaft 6 to rotate in both directions to a certain extent. The bidirectional motor 2 also has an obstruction protection function; when it encounters significant resistance and can no longer move, it stops rotating.

[0034] Each switch piece 8 is used for fixed mounting on a switch 11. In some embodiments, the switch piece 8 can be fixed to the center of the switch 11 with adhesive. In some embodiments, such as Figure 1 As shown, the switch piece 8 can be fixed to the switch 11 by the snap-fit ​​piece 10. Specifically, the snap-fit ​​piece 10 can be fixed to the switch 11 by glue. The bottom of the switch piece 8 is provided with a slot for connecting and fixing with the snap-fit ​​piece 10.

[0035] Each switch piece 8 is fixedly connected to a simple clutch 7, which is used to engage the rotating shaft 6 when energized and disengage the rotating shaft 6 when de-energized.

[0036] In some embodiments, such as Figure 3 As shown, the rotating shaft 6 is made of iron. The simple clutch 7 includes a ring bracket 23 and multiple sets of electromagnets 12. The multiple sets of electromagnets 12 are arranged around the rotating shaft 6. The ring bracket 23 is provided with multiple grooves to accommodate the electromagnets 12. Each set of electromagnets 12 is connected to the bottom of the corresponding groove through a first spring 14. When the electromagnets 12 are energized, they generate magnetic force to attract the rotating shaft 6, thereby driving the switch piece 8 to rotate. At this time, the first spring 14 is stretched. When the electromagnets 12 are de-energized, they lose their magnetic force, the first spring 14 returns to its original state, and the electromagnets 12 are disengaged from the rotating shaft 6.

[0037] The end of the electromagnet 12 that engages the rotating shaft is designed with an arc shape, so that the electromagnet 12 can better engage the rotating shaft 6.

[0038] In a preferred embodiment, an anti-slip head 13 is provided at one end of the electromagnet 12 that engages the rotating shaft 6, which makes the engagement between the electromagnet and the rotating shaft more stable after the electromagnet 12 engages the rotating shaft 6.

[0039] In other embodiments, such as Figure 4 As shown, the rotating shaft 6 is made of non-ferrous metal. The simple clutch 7 includes an annular bracket 23, multiple sets of electromagnets 12, and multiple rubber sheets 17. The multiple sets of electromagnets 12 are fixed on the annular bracket 23 along the circumferential direction. The multiple rubber sheets 17 are arranged around the rotating shaft 6. One end of each rubber sheet 17 is fixed on the annular bracket 23, and the other end is connected to a magnet 16. Each magnet 16 corresponds to a set of electromagnets 12. When the electromagnet 12 is not energized, the magnet 16 is attracted to the iron core of the corresponding electromagnet 12. When the electromagnet 12 is energized, it generates a magnetic force in the same direction as the magnet 16, causing the like poles of the magnet 16 to repel each other and drive the rubber sheet 17 to stick to the rotating shaft 6, thereby enabling the rotating shaft 6 to drive the switch piece 8 to rotate. When the electromagnet 12 is de-energized, the magnet 16 is attracted back to the electromagnet 12, thus disengaging from the rotating shaft 6.

[0040] The bidirectional motor 2 is connected to the base 1 through a height adjustment mechanism. The height adjustment mechanism ensures that the bidirectional motor 2 can only adjust its distance from the wall within a certain range. The bidirectional motor 2 and the rotating shaft 6 can be adjusted to be at the same height through the height adjustment mechanism.

[0041] In some embodiments, such as Figure 5 As shown, the height adjustment mechanism includes a motor enclosure 19 and a second spring 18. The motor enclosure 19 is mounted on the base 1, and the bidirectional motor 2 is located inside the motor enclosure 19. The bidirectional motor 2 is connected to the base 1 via the second spring 18. Under the restriction of the motor enclosure 19, the bidirectional motor 2 can only move up and down along the height direction of the enclosure.

[0042] The second spring 18 is initially in a compressed state. After the bidirectional motor 2 is raised to the corresponding position, the second spring 18 extends to fix the bidirectional motor 2 in place. The spring connection between the bidirectional motor 2 and the base 1 allows the position of the bidirectional motor 2 to be infinitely adjustable.

[0043] In other embodiments, such as Figure 6 As shown, the height adjustment mechanism includes a motor enclosure 19 and a motor baffle 21. The motor enclosure 19 is mounted on the base 1, and the bidirectional motor 2 is located inside the motor enclosure 19. The motor enclosure 19 has multiple latching slots 22, and the bidirectional motor 2 is connected to multiple sets of motor latches 20. The bidirectional motor 2 and the motor enclosure 19 can be connected via the motor latches 20 and the latching slots 22. The height of the bidirectional motor 2 can be adjusted by adjusting the connection position of the motor latches 20 and the latching slots 22. The motor baffle 21 is used to fix the bidirectional motor 2 between the rear end of the bidirectional motor 2 and the motor enclosure 19 after the motor latches 20 are connected to the latching slots 22. After the motor baffle 21 is pulled out, the bidirectional motor 2 moves backward, allowing the motor latches 20 to disengage from the latching slots 22.

[0044] When it is necessary to adjust the height of the bidirectional motor 2, lift the bidirectional motor 2 to the corresponding position and move it forward so that the motor buckle 20 enters the buckle hole 22 on the motor enclosure 19, and then insert the motor baffle 21 to fix the bidirectional motor 2.

[0045] like Figure 1 and Figure 2 As shown, the device also includes a protective cover 9, which is connected to the bidirectional motor 2. The height of the protective cover 9 can be adjusted according to the height of the bidirectional motor 2. In a preferred embodiment, the protective cover 9 is detachably connected to the bidirectional motor 2.

[0046] like Figure 9 As shown, the protective cover 9 has multiple parallel power supply circuits 26 inside, each of which can be used to power a simple clutch 7.

[0047] The power supply circuit 26 is made of exposed conductive metal, so that each power supply circuit 26 can conduct electricity at any position.

[0048] like Figure 7 and Figure 8 As shown, the power supply circuit 26 is electrically connected to the electromagnet 12 in the ring bracket 23 through the contact point 25.

[0049] Specifically, the outer side of the annular bracket 23 is provided with a housing 24, which is fixedly connected to the protective cover 9 and does not rotate with the rotation of the shaft 6. An opening slot 27 is provided on the top of the housing 24, and the housing 24 is also provided with adjustable openings 28 of different numbers that communicate with the opening slot 27. The positions of the adjustable openings 28 of different numbers correspond one-to-one with the positions of the power supply circuits 26 in the protective cover 9. The contact point 25 has a convex structure, including a circuit connection end 29 at the top and clutch connection ends 30 and touch ends 31 at the left and right ends. The circuit connection end 29 and the clutch connection end 30 can conduct electricity, while the touch end 31 is an insulating end. The circuit connection end 29 is housed in the opening slot 27 and is in contact with a power supply circuit 26 in the protective cover 9. The touch end 31 passes through the adjustable opening 28 and protrudes from it. The clutch connection end 30 is electrically connected to each electromagnet 12 in the annular bracket 23 via a wire. The position of the circuit connection terminal 29 can be adjusted by manually moving the touch terminal 31 to different numbered adjustable openings 28, so that the circuit connection terminal 29 can be electrically connected to different power supply circuits 26 in the protective cover 9, thereby enabling each simple clutch 7 to be powered by a power supply circuit 26 in the protective cover 9.

[0050] The number of the adjustable opening 28 can correspond to the serial number of the switch 11, so that the controller 3 can directly select which number of the power supply circuit 26 to supply power, thereby directly controlling the corresponding serial number of the switch 11.

[0051] In some embodiments, such as Figure 2 As shown, the rotating shaft 6 can be designed in multiple segments, and the segments can be connected by detachable methods such as mortise and tenon joints or snap-fit ​​joints, allowing users to flexibly assemble or disassemble the switch group according to the required length. The length of the rotating shaft 6 is required to cover all switches 11 in the switch group.

[0052] The protective cover 9 can also adopt a multi-section detachable structure, which can be assembled or disassembled according to the length of the switch assembly. Combined with... Figure 9 As shown, the power supply circuit 26 of each protective cover 9 protrudes slightly at the front end so that the power supply circuit 26 of two adjacent protective covers 9 can be electrically connected through terminal contact, so that the power supply circuit 26 can be continuously connected after multiple protective covers 9 are interconnected.

[0053] like Figure 3 or Figure 4 As shown, the outer ring of the simple clutch 7 is also provided with a roller 15. The protective cover 9 can be connected to the ring bracket 23 through the roller 15. The roller 15 can rotate freely inside the protective cover 9, so that the simple clutch 7 can rotate freely inside the protective cover 9.

[0054] The wireless receiver 4 connects to devices such as mobile phones and remote controls via wireless transmission methods such as Bluetooth, infrared, and WIFI.

[0055] Users can send switch control commands [serial number, rotation direction] via mobile phones, remote controls, or other devices. The serial number indicates the number of the simple clutch to be controlled, and the rotation direction can be represented by 0 or 1, where 0 is clockwise and 1 is counterclockwise. For example, [1,0] means that the simple clutch 7 with serial number 1 engages the shaft 6 and rotates clockwise, thereby changing the state of the corresponding conventional switch 11 and realizing the "on" or "off" control of the corresponding switch 11.

[0056] The wireless receiver 4 receives the switch control command and sends it to the controller 3.

[0057] According to the received switch control command, the controller 3 controls the corresponding power supply circuit 26 to energize the electromagnet 12 in the simple clutch 7 with the corresponding serial number, so that the simple clutch 7 engages the rotating shaft 6. At the same time, the controller controls the bidirectional motor 2 to drive the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the switch piece 8 to rotate, thereby driving the corresponding switch 11 to rotate to open or close the corresponding switch 11. When the bidirectional motor 2 can no longer move, it stops rotating due to the large resistance, thus completing the process of remotely controlling the switch.

[0058] In use, the bidirectional motor 6, shaft 6, protective cover 9, etc. are assembled according to the length required by the traditional switch assembly. A switch piece 8 is installed on each switch, and the height of the bidirectional motor 2 is adjusted according to the position of the shaft 6. The position of each contact point 25 is adjusted by manually moving the touch end 31 to the adjustable opening 28 with different numbers, so that the different power supply circuits in the protective cover 9 are electrically connected to the simple clutch 7 with the corresponding number.

[0059] The remote control command is received by the wireless receiver 4, and the bidirectional motor 2 is controlled by the controller 3 to drive the rotating shaft 6 to rotate in the forward or reverse direction, thereby changing the switch state.

[0060] The rotating shaft 6 is connected to the switch 11 by a simple clutch 7. When no specified sequence number command is received, the simple clutch 7 is in the disengaged state, and the rotation of the rotating shaft 6 will not affect the state of the switch with that sequence number. When a specified sequence number command is received, the simple clutch 7 will engage the rotating shaft 6, and the rotating shaft 6 will drive the simple clutch 7 to rotate to perform the switching operation, thereby realizing the simultaneous control of multiple switches.

[0061] When the simple clutch 7 is not given a command, it is in the disengaged state. At this time, the position of the simple clutch 7 on the rotating shaft 6 can be moved freely. The best pasting position of the switch piece 8 and the clip piece 10 can be selected according to the interval between the switches. Any extra switch piece 8 can be removed from the tail of the rotating shaft 6 or pasted on the same switch.

[0062] Since the simple clutch 7 is in the disengaged state when no command is received, manual operation of the switch is not affected, and therefore does not affect the normal pressing of the original switch. Users can choose to remotely control the switch or manually control the switch according to their needs.

[0063] The device of this invention is simple in design, relatively inexpensive compared to independent smart switches, easy to install, will not damage the switch or the wall, and can control multiple switches simultaneously.

[0064] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. All technical solutions obtained by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the present invention.
