Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent switch technology, specifically to a combined switch. Background Technology
[0002] Traditional interconnected switches consist of two or more independent switching units. Each switching unit includes a control board and a high-voltage board for electrical connection to the mains power. The high-voltage board is equipped with relays for electrical connection to external appliances. The control board controls the relays and also has a control panel for users to input control signals to the control board. When the control board controls the relays to close, the high-voltage board supplies power to the external appliances through the relays. Conversely, when the control board controls the relays to open, the high-voltage board cannot supply power to the external appliances through the relays.
[0003] When operating, the integrated switch requires power to the control board. Current power supply methods typically involve installing a step-down circuit on the power board of each switch unit. This step-down circuit connects to the control board, which converts the 220V AC mains power to 5V DC before supplying it to the control board. This method requires a step-down circuit on each switch unit's power board, resulting in high costs. Furthermore, to enable remote operation of the integrated switch, current systems include a wireless communication module on each switch unit's control board for wireless connection to mobile phones or other smart devices. This allows users to remotely operate the integrated switch by inputting control signals to the control board via the wireless communication module using their smart devices. This remote operation method also requires a wireless communication module on each switch unit's control board, further increasing costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a combined switch that can reduce power supply costs and wireless communication costs.
[0005] To solve the above-mentioned technical problems, this utility model provides a combined switch, including multiple switch units. Each switch unit includes a control board and a power supply board. The power supply board is electrically connected to the mains power for power supply. The power supply board is equipped with a relay for electrically connecting to external electrical appliances for power supply. The control board controls and connects to the relay. In one switch unit, the power supply board is electrically connected to the control board through a step-down circuit. The control board is equipped with a wireless communication module for wirelessly connecting to smart devices. A connecting board is provided between the control boards of two adjacent switch units for electrical and communication connection.
[0006] Furthermore, the power board is provided with a pin header, and the control board is provided with a pin socket. The pin header on the power board is inserted into the pin socket on the control board, so that the control board controls the relay on the power board through the pin socket and the pin header.
[0007] Furthermore, the step-down circuit is located on the power supply board, with its input terminal connected to the mains power and its output terminal connected to the control board via a pin header and a pin socket.
[0008] Furthermore, the connection board is equipped with power transmission cables and signal transmission cables to enable electrical and communication connections between the control boards of two adjacent switching units.
[0009] Furthermore, each switching unit includes a high-voltage base and a high-voltage cover, wherein the high-voltage plate is installed in the high-voltage base and the high-voltage cover is installed on the high-voltage base to cover the high-voltage plate.
[0010] Furthermore, the power supply cover plate has a first through hole for the pin header to pass through. After the power supply cover plate is installed on the power supply base shell to cover the power supply plate, the pin header passes through the first through hole.
[0011] Furthermore, each switching unit includes a control base and a control cover, wherein the control board is installed in the control base and the control cover is installed in the control base to cover the control board.
[0012] Furthermore, the control base has a second through hole for the needle holder to pass through. After the control plate is installed in the control base, the needle holder passes through the second through hole.
[0013] Furthermore, the control panel is provided with control buttons, and the control cover has a third through hole for the control buttons to pass through. After the control cover is installed in the control bottom shell to cover the control panel, the control buttons pass through the third through hole.
[0014] Furthermore, each switch unit includes a control panel mounted on a control cover plate, which contacts control buttons extending from a third through hole.
[0015] This utility model has the following advantages: The integrated switch includes multiple switch units. In one switch unit, the high-voltage board is electrically connected to the control board through a step-down circuit. The control board is equipped with a wireless communication module for wirelessly connecting to smart devices. A connecting plate is provided between the control boards of two adjacent switch units for electrical and communication connection. That is, only one switch unit is equipped with a step-down circuit and a wireless communication module. The control boards of the other switch units can draw power and receive signals from the control board of the other switch unit through the connecting plate. Therefore, the other switch units do not need to be equipped with step-down circuits and wireless communication modules, which reduces the power supply cost and wireless communication cost of the integrated switch. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of a combined switch.
[0017] Figure 2 This is a schematic diagram of one of the switching units. Detailed Implementation
[0018] The present invention will be further described in detail below with reference to specific embodiments.
[0019] Interlocking switches, such as Figure 1 As shown, it includes four switch units 1 arranged side by side, such as Figure 2 As shown, each switch unit 1 includes a power supply section and a control section. The power supply section includes a high-voltage base shell 2, a high-voltage board 3, and a high-voltage cover plate 4. The control section includes a control base shell 5, a control board 6, a control cover plate 7, and a control panel 8. It should be noted that the specific number of switch units 1 in the integrated switch can be changed to two or more other numbers depending on the actual situation, such as two, three, or five.
[0020] In the power supply section, the high-voltage board 3 is electrically connected to the mains power supply for power generation, and is equipped with a relay (not shown in the figure) for electrically connecting to external electrical appliances for power supply. When the relay is closed, the high-voltage board 3 supplies power to the external electrical appliances through the relay; when the relay is open, the high-voltage board 3 cannot supply power to the external electrical appliances through the relay. The high-voltage board 3 has a pin header 31 for electrically connecting to the relay, and the high-voltage cover plate 4 has a first through hole 41 for the pin header 31 to pass through. During the assembly of the power supply section, the high-voltage board 3 is installed in the high-voltage base shell 2, and the high-voltage cover plate 4 is installed on the high-voltage base shell 2 to cover the high-voltage board 3, so that the pin header 31 on the high-voltage board 3 passes through the first through hole 41 of the high-voltage cover plate 4, thus completing the assembly of the power supply section.
[0021] In the control unit, the control board 6 is equipped with a controller, such as an MCU controller. The control board 6 has a needle holder 61 electrically connected to the controller and four control buttons 62. The control base 5 has a second through hole 51 through which the needle holder 61 passes, and the control cover 7 has four third through holes 71 through which the control buttons 62 pass. During assembly, the control board 6 is installed in the control base 5, with the needle holder 62 passing through the second through hole 51. The control cover 7 is installed on the control base 5 to cover the control board 6, with the four control buttons 62 on the control board 6 passing through the four third through holes 71 on the control cover 7. Then, the control panel 8 is installed on the control cover 7, so that the control panel 8 contacts the four control buttons 62 passing through the third through holes 71. This completes the assembly of the control unit. The user can input control signals to the control board 6 by pressing the control buttons 62 on the control panel 8.
[0022] After assembling the power supply unit and the control unit, the control base 5 of the control unit can be installed on the high-voltage cover 4 of the power supply unit, so that the pin header 31 on the high-voltage board 3 is inserted into the pin seat 61 at the bottom of the control unit 6. This completes the assembly and connection between the power supply unit and the control unit, forming the switch unit 1. After the assembly and connection between the power supply unit and the control unit is completed, the control board 6 controls the relay on the high-voltage board 3 through the pin seat 61 and the pin header 31, so that the control board 6 can control the relay on the high-voltage board 3 to close or open.
[0023] One of the switching units 1 in the integrated switch is the main switching unit. Its power board 3 has a step-down circuit (not shown in the figure). The input of this step-down circuit is connected to the mains power, and the output is connected to the control board 6 via pin header 31 and pin socket 61. The power board 3 converts the 220V mains power to 5V DC power through the step-down circuit and then transmits it to the control board 6 to provide power. In this main switching unit, the control board 6 also has a wireless communication module (not shown in the figure) for wirelessly connecting to mobile phones or other smart devices. Users can operate smart devices to input control signals to the control board 6 through the wireless communication module. The other three switching units 1 of the integrated switch are auxiliary switching units and do not have step-down circuits or wireless communication modules.
[0024] In the four switching units 1 of the integrated switch, a connecting plate 9 is provided between the control boards 6 of two adjacent switching units 1. This connecting plate 9 is equipped with power transmission cables and signal transmission cables, enabling electrical and communication connections between the control boards 6 of adjacent switching units 1. This allows the auxiliary switching unit to draw power or receive signals from the main switching unit via the connecting plate 9, thus enabling the user to remotely control all four switching units 1 through a smart device. For example… Figure 1The first switch unit 1 from left to right is the main switch unit, and the other switch units 1 are auxiliary switch units. The power board 3 of the first switch unit 1 is equipped with a step-down circuit, and the control board 6 is equipped with a wireless communication module. The other switch units 1 are not equipped with step-down circuits and wireless communication modules. There are connecting plates 9 between the control boards 6 of the first switch unit 1 and the second switch unit 1, between the control boards 6 of the second switch unit 1 and the third switch unit 1, and between the control boards 6 of the third switch unit 1 and the fourth switch unit 1. After the power board 3 of the first switch unit 1 draws power from the mains, it converts the 220V mains power into 5V DC power through the step-down circuit to supply the control board 6. This 5V DC power is also supplied to the control boards 6 of the second, third, and fourth switch units 1 through the connecting plates 9. When a user needs to remotely control the first switch unit 1 (main switch unit), a wireless signal can be sent to the wireless communication module on the control board 6 of the first switch unit 1 via a smart device. After receiving the wireless signal, the control board 6 controls the relay on the high-voltage board 3 of the first switch unit 1 to close, thus enabling remote operation of the high-voltage board 3 of the first switch unit 1 to supply power to external electrical appliances via the relay. When a user needs to remotely control the second switch unit 1 (auxiliary switch unit), a wireless signal can be sent to the wireless communication module on the control board 6 of the first switch unit 1 via a smart device. After receiving the wireless signal, the control board 6 transmits the wireless signal to the control board 6 of the second switch unit 1 via the connection board 9. After receiving the wireless signal, the control board 6 of the second switch unit 1 controls the relay on the high-voltage board 3 of the second switch unit 1 to close, thus enabling remote operation of the high-voltage board 3 of the second switch unit 1 to supply power to external electrical appliances via the relay. When a user needs to remotely control the third switch unit 1 or the fourth switch unit 1, the control principle is basically the same as that of the second switch unit 1. The difference is that when remotely controlling the third switch unit 1, the wireless signal needs to pass through the control board 6 of the second switch unit 1 before being transmitted to the control board 6 of the third switch unit 1. When remotely controlling the fourth switch unit 1, the wireless signal needs to pass through the control boards 6 of the second switch unit 1 and the control board 6 of the third switch unit 1 before being transmitted to the control board 6 of the fourth switch unit 1.
[0025] In summary, the integrated switch in this embodiment only sets up a step-down circuit and a wireless communication module in one switch unit 1 (main switch unit). The control boards 6 of the other switch units 1 (auxiliary switch units) can draw power and receive signals from the control board 6 of the main switch unit 1 through the connecting board 9. Therefore, the other switch units 1 (auxiliary switch units) do not need to set up step-down circuits and wireless communication modules, which reduces the power supply cost and wireless communication cost of the integrated switch.
[0026] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
