[0036] In the description of the present invention, unless otherwise clearly specified and limited, the term "connection" and other terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0038] Please refer to Figure 1 As shown, an embodiment of the present invention proposes a receiver, comprising: a shell (not shown in the figure) and a communication module 1, wherein the shell has a receiving cavity; the communication module 1 is used to connect the target wire (not shown in the figure) that is connected or connected, and the communication module 1 is arranged in the receiving cavity. The target wire can be a power line, such as the live wire L and the neutral wire N of the connected mains, or the live wire L and the neutral wire N of the connected electrical appliance; the target wire can also be a control wire, such as a control wire for inputting or outputting control signals, and the target wire can also be other wires that can be connected to the communication module 1, which is not limited here.
[0039] The communication module 1 includes: a communication unit 11, a signal monitoring unit 12, and a power supply unit 13. The communication unit 11 is directly or indirectly electrically connected to the target wire. For example, in an optional embodiment, the city power flowing through the target wire is rectified, filtered, stepped down, etc., and then outputs a voltage to the communication unit 11, so that the communication unit 11 can be powered on and work. The power supply unit 13 is electrically connected to the communication unit 11 so that it can switch the on and off state under the control of the communication unit 11; the power supply unit 13 is electrically connected to the electrical appliance to control the working state of the electrical appliance such as the power supply state, wherein the electrical appliance is an electrical device such as a lamp, a smart curtain, etc. The signal monitoring unit 12 is electrically connected to the communication unit 11, and is used to monitor external signals such as external wired signals, wireless signals, etc., so that the communication unit 11 can control the on and off state of the power supply unit 13 according to the external signal monitored by the signal monitoring unit 12, and then control the working state of the electrical appliance connected to the power supply unit 13.
[0040] Further, the power taking unit 13 includes an energy storage switch 131 and a power taking switch 132; the energy storage switch 131 is operably connected to the power taking switch 132, for example, the energy storage switch 131 can be directly or indirectly electrically connected to the power taking switch 132, and is configured to be controlled by the power taking switch 132 to be turned on or off. The power taking switch 132 is operably connected to the communication unit 11, for example, the power taking switch 132 can be directly or indirectly electrically connected to the communication unit 11, and is configured to be suitable for receiving a control signal from the communication unit 11, so that when the electrical appliance is in a working state, the energy storage switch 131 is continuously turned on in a first time period to form a first power supply stage, and is continuously turned off in a second time period to form a second power supply stage. In addition, in order to ensure that the electrical appliance can be controlled to be in a working state in both the first time period and the second time period, the duration of the first time period is set to be greater than or equal to the duration of the second time period in this embodiment.
[0041] Among them, the energy storage switch 131 has the function of storing energy, that is, when the energy source is turned on, it can store a certain amount of energy while working, and when the energy source is removed, it can also use the stored energy to keep working for a period of time. Exemplarily, the energy storage switch 131 may include a combination of one or more voltage-type energy storage devices, current-type energy storage devices, etc. In addition, a corresponding delay control circuit may be provided, which is not limited here. The power switch 132 can receive the control signal of the communication unit 11, control its own connection or disconnection according to the control signal, and then control whether to provide an energy source for the energy storage switch 131, thereby directly or indirectly controlling the working mode of the energy storage switch 131 such as connection, energy storage, delay control, etc.
[0042] In this embodiment, after the power switch 132 receives the control signal of the communication unit 11, it is continuously turned on in the first time period, thereby continuously supplying energy to the energy storage switch 131; the energy storage switch 131 can store a certain amount of energy while working in the first time period, for example, the energy storage switch 131 stores a certain amount of energy when controlling the electrical appliance to be in a working state, i.e., a power supply state, which is regarded as the energy storage switch 131 being able to control the electrical appliance to be in a working state in the first power supply stage. After the power switch 132 receives the control signal of the communication unit 11, it is continuously disconnected in the second time period, and the power switch 132 cannot supply energy to the energy storage switch 131. The energy storage switch 131 can continue to work for a period of time in the second time period using its own stored energy, for example, the energy storage switch 131 continues to control the electrical appliance to be in a working state in the second time period, which is regarded as the energy storage switch 131 still being able to control the electrical appliance to be in a working state in the second power supply stage. It can be seen that the electrical appliance can be controlled to be in a working state when the power switch 132 is turned on or off, that is, the receiver does not need to be in a high-power consumption state all the time to control the power supply of the electrical appliance, and the energy storage switch 131 in the receiver does not need to provide it with an energy source all the time. It can use the stored energy to continue to control the power supply of the electrical appliance when there is no energy source input, thereby effectively reducing power consumption.
[0043] In this embodiment, it is considered that in actual application, the electrical appliances may be in a working state, i.e., a power supply state, for a long time. If the receiver is also in a continuous high-power consumption state to support the working state of the electrical appliances, the long-term continuous high-power consumption of the receiver will cause its power consumption to be too high. Therefore, in this embodiment, the communication unit 11 of the receiver sends a control signal to the power switch 132 after receiving the external signal. The power switch 132 is continuously turned on in the first time period according to the control signal to form the first power supply stage of the energy storage switch 131, and is continuously turned off in the second time period to form the second power supply stage of the energy storage switch 131; the electrical appliances are in a working state in both the first power supply stage and the second power supply stage. Since the energy storage switch 131 in the receiver can still keep the electrical appliances in a working state when the power switch 132 is disconnected, that is, the receiver does not need to be in a continuously connected high-power consumption state, thereby reducing the power consumption of the receiver and avoiding the temperature increase in the receiver caused by excessive power consumption, thereby improving the service life and safety of the receiver.
[0044] Further, in an optional embodiment, the communication unit 11 is configured to send a first control signal to the power switch 132 after receiving the external signal monitored by the signal monitoring unit 12; the power switch 132 is configured to be suitable for receiving the first control signal so as to be continuously connected within a third time period when the electrical appliance is in a working state to form a third power supply stage of the energy storage switch 131; the duration of the third time period is greater than or equal to the duration of the first time period.
[0045] In this embodiment, before the energy storage switch 131 is delayed controlled by the on and off of the power taking switch 132, considering the characteristics of some types of energy storage switches 131, such energy storage switches 131 need to have a certain amount of energy before they can be activated to control the power supply of the electrical appliance, or can better realize the subsequent delay control function. Otherwise, if such energy storage switches 131 are directly delayed controlled, the electrical appliance may not be able to be continuously in a working state, that is, it cannot be continuously powered. Therefore, in this embodiment, after the communication unit 11 receives the external signal monitored by the signal monitoring unit 12, it first sends a first control signal to the power taking switch 132; after receiving the first control signal, the power taking switch 132 is continuously turned on and supplies power to the energy storage switch 131. After receiving the energy supply from the power taking switch 132, the energy storage switch 131 is activated to control the electrical appliance to be in a working state, that is, a power supply state, and it is considered that the energy storage switch 131 can control the electrical appliance to be in a working state in the third power supply stage. Among them, the first control signal can be set according to the connection condition of the power switch 132. For example, in some embodiments, if a low-level signal can turn on the power switch 132, then the first control signal can be a low-level signal that lasts for a third period of time; if a high-level signal can turn on the power switch 132, then the first control signal can be a high-level signal that lasts for the third period of time. Of course, the first control signal is not limited to other types of signals.
[0046] In addition, in order to ensure that the energy storage switch 131 is continuously turned on during the third time period to form a third power supply stage, the duration of the third time period is set to be greater than or equal to the duration of the first time period in this embodiment. In this way, it can be ensured that during the third time period, the energy storage switch 131 receives the energy supplied by the power taking switch 132 and is activated to control the electrical appliance to be in a working state, i.e., a power supply state, which is beneficial for the subsequent energy storage switch 131 to stably delay control the working state of the electrical appliance, thereby improving the reliability of the receiver's operation and avoiding the occurrence of unstable power supply to the electrical appliance electrically connected to the receiver.
[0047] Further, in some embodiments, after the communication unit 11 sends the first control signal to the power switch 132 in the third time period to activate the energy storage switch 131 to control the working state of the electrical appliance, the communication unit 11 may send a second control signal to the power switch 132, so that the power switch 132 receives the second control signal, and in the working state of the electrical appliance, the energy storage switch 131 is continuously connected in the first time period to form the first power supply stage, and is continuously disconnected in the second time period to form the second power supply stage of the energy storage switch 131. In this way, in this embodiment, after ensuring that the energy storage switch 131 is activated to control the electrical appliance to be in the working state, the power switch 132 is turned on in the first time period to supply energy to the energy storage switch 131 so that the energy storage switch 131 can control the electrical appliance to be in the working state according to the energy supply, and the power switch 132 is continuously disconnected in the second time period, so that the energy storage switch 131 continues to control the electrical appliance to be in the working state using its own stored energy. It can be seen that when the power switch 132 in the receiver is disconnected, the energy storage switch 131 can still keep the electrical appliance in working state, that is, the receiver does not need to be in a high power consumption state all the time, thereby reducing the power consumption of the receiver. It should be noted that in this embodiment, the order of the first power supply stage and the second power supply stage of the energy storage switch 131 is not limited, that is, after the communication unit 11 sends the second control signal to the power switch 132, in an optional embodiment, the power switch 132 can be continuously turned on in the first time period to form the first power supply stage of the energy storage switch 131, and then be continuously disconnected in the second time period to form the second power supply stage of the energy storage switch 131. In another optional embodiment, the power switch 132 can be continuously disconnected in the second time period to form the second power supply stage of the energy storage switch 131, and then be continuously turned on in the first time period to form the first power supply stage of the energy storage switch 131, according to the second control signal. Of course, the first power supply stage and the second power supply stage of the energy storage switch 131 are not limited to cycle according to a set period and sequence.
[0048] In addition, in this embodiment, the sum of the duration of the first time period and the duration of the second time period is set as the total duration, and the ratio of the duration of the first time period to the total duration is set to be greater than or equal to 50%. In this way, it can be ensured that the energy storage switch 131 can stably delay control the working state of the electrical appliance, while also maintaining the power consumption of the receiver at a low power consumption.
[0049] Furthermore, if Figure 2As shown, in some embodiments, the energy storage switch 131 includes an energy storage unit 1311 and at least one magnetron electrode pair; the magnetron electrode pair is electrically connected to the electrical appliance; the magnetron electrode pair includes two conductive contacts 1312, 1313, for example, the two conductive contacts 1312, 1313 of the magnetron electrode pair can be electrically connected to the two ends of the electrical appliance respectively, or one of the two conductive contacts 1312, 1313 of the magnetron electrode pair is electrically connected to the target wire such as the live wire L, and the other conductive contact 1312 is electrically connected to the electrical appliance via the control line OUT1. As long as the power supply and power off of the electrical appliance can be controlled respectively by connecting and disconnecting the two conductive contacts, it does not depart from the protection scope of this embodiment. If the two conductive contacts 1312 and 1313 in the magnetically controlled electrode pair are connected, the electrical appliance is powered; if the two conductive contacts 1312 and 1313 in the magnetically controlled electrode pair are not connected, the electrical appliance is powered off; the energy storage unit 1311 includes an iron core 13111 and a coil 13112 wound around the iron core, and the two ends of the coil 13112 are respectively connected to a DC power supply DVCC and the power switch 132, and then, when the power switch 132 is turned on, the two conductive contacts 1312 and 1313 in the magnetically controlled electrode pair can be connected in response to the magnetic attraction generated by the iron core 13111; within a specified time after the power switch 132 is turned off, the two conductive contacts 1312 and 1313 in the magnetically controlled electrode pair can be connected in response to the energy stored in the energy storage unit 1311; wherein the duration of the second time period is less than or equal to the specified time. In this embodiment, if the power switch 132 is continuously disconnected during the second time period, the power switch 132 cannot supply energy to the energy storage switch 131, such as the iron core 13111 and the coil 13112 in the energy storage unit 1311, and the energy storage switch 131 can continue to work for a period of time in the second time period using its own stored energy. For example, after the power switch 132 is disconnected, the energy storage unit 1311 loses its energy supply, but the electric energy in the coil 13112 in the energy storage unit will not disappear instantly. Within a specified time, the combination of the iron core 13111 and the coil 13112 in the energy storage unit 1311 still has a certain magnetic attraction, and the two conductive contacts 1312 and 1313 in the magnetic control electrode pair can be connected in response to the magnetic attraction of the energy storage unit 1311 within the specified time, so as to achieve that the electrical appliance can still be controlled to be in a working state after the power switch 132 is disconnected.And it is only necessary to control the duration of the power switch 132 being disconnected, that is, the duration of the second period is less than or equal to the specified time, and then the magnetic attraction of the energy storage unit 1311 within the specified time can be used to control the connection of the magnetically controlled electrodes and then control the electrical appliance to be in a working state after the power switch 132 is disconnected, and then the energy storage unit 1311 is powered by the power switch 132 to provide magnetic attraction. In this way, it can be ensured that the electrical appliance can be kept in a working state when the power switch 132 is disconnected and connected, that is, the receiver does not need to be in a high power consumption state of being connected to supply energy to the energy storage unit 1311, thereby reducing the power consumption of the receiver.
[0050] Furthermore, in some embodiments, the power taking unit 13 further includes a discharge subunit 133, which is electrically connected between the two ends of the coil 13112 and is configured to be suitable for short-circuiting the coil 13112 during at least a portion of the second power supply stage. Since the coil 13112 in the energy storage unit 1311 will have a relatively high reverse voltage at the moment of power failure when the power taking switch 132 is disconnected, the reverse voltage is likely to damage the power taking switch 132 electrically connected to the coil 13112. Therefore, in this embodiment, the discharge subunit 133 is provided at both ends of the coil 13112, so that when the reverse voltage is generated, the reverse voltage is released through the discharge path formed by the discharge subunit 133 without damaging the power taking switch 132.
[0051] Furthermore, if Figure 3 As shown, in an optional implementation, the energy storage switch 131 in this embodiment may be a relay U1, and the discharge subunit 133 may include a diode D7, the anode of the diode D7 is electrically connected to the power switch 132, and the cathode D7 of the diode is electrically connected to the DC power supply DVCC to form a discharge path for the energy storage switch 131 in the second time period. The power switch 132 may include a switch tube, such as a MOS tube or a triode. In this embodiment, the power switch 132 includes a triode Q2 as an example for description.
[0052] Specifically, the power switch 132 may also include a resistor voltage divider circuit, such as resistor R10, resistor R12, and resistor R14 in the figure. Since the coil of the relay U1 will have a reverse voltage at the moment of power failure, the reverse voltage is relatively high, which may be several times higher than the voltage of the DC power supply, and this reverse voltage is likely to burn out the transistor. Therefore, a diode D7 is provided in this embodiment to provide a discharge path for the reverse voltage at the moment of power failure of the relay U1, so as to effectively protect the driving transistor Q2. The power switch 132 may also include an indicator LED4, which is used to indicate that the power switch 132 is controlled by the on or off state of the communication unit 11, that is, the on and off state of the transistor Q2 in the power switch 132. Among them, the collector of the transistor Q2 is electrically connected to the anode of the diode D7, the base of the transistor Q2 is electrically connected to the communication unit 11 via the resistor R10, the emitter of the transistor Q2 is grounded, the base of the transistor Q2 is also grounded via the resistor R12, the anode of the LED4 is electrically connected to the communication unit 11, and the cathode of the LED4 is grounded via the resistor R14.
[0053] The relay U1 includes a pair of magnetically controlled electrodes, and the pair of magnetically controlled electrodes includes two conductive contacts, which can be a moving contact and a static contact that cooperate with an armature. When the control signal sent by the communication unit 11 is a high-level signal, the transistor Q2 is turned on, and the coil wound around the iron core of the relay U1 is energized, and current passes through the coil. According to the magnetic effect of the current, the coil of the relay U1 has magnetism. Under the action of electromagnetic attraction, the armature will overcome the pulling force of the return spring and be attracted to the iron core, thereby driving the moving contact of the armature and the static contact (normally open contact) to attract, and then the power supply channel of the electrical appliance electrically connected to the contact is turned on, and the electrical appliance is in a power supply state.
[0054] When the control signal sent by the communication unit 11 is a low-level signal, the transistor Q2 is disconnected and the coil of the relay U1 is de-energized. After the coil is de-energized, the electromagnetic attraction will disappear after a period of time, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) are released, and the power supply channel of the electrical appliance electrically connected to the contact is disconnected, and the electrical appliance is in a power-off state.
[0055] In this embodiment, it is considered that if the communication unit 11 sends a high-level control signal for a long time, the transistor Q2 is continuously turned on, and the coil of the relay U1 will also work for a long time, resulting in high power consumption, and the temperature of the coil of the relay U1 will also increase, which is not conducive to the service life and safety of the receiver. Therefore, the control signal sent by the communication unit 11 in this embodiment can be a pulse width modulation (PWM) signal, and its frequency can be set according to actual needs. When the PWM signal sent by the communication unit 11 is high, the relay U1 is attracted; when the high level ends, the transistor Q2 works in the cut-off area, at this time, the current in the coil of the relay U1 will not disappear in an instant, and within a certain period of time, the relay U1 still has magnetism and can maintain the attracted state. It only needs to set the low-level time of the PWM signal to be less than the demagnetization time of the relay U1 to ensure the continuous attraction state of the relay U1. Therefore, in this embodiment, when the electrical appliance is controlled to be in the power supply state, the coil of the relay U1 does not need to be in the working state for a long time, which can effectively reduce power consumption and reduce the temperature of the coil of the relay U1. In addition, considering that if the PWM signal is directly output to control the relay U1, the high-level signal in the PWM signal may not be sufficient to activate the relay U1 to energize, resulting in unstable power supply status of the electrical appliance in the subsequent operation, in an optional implementation, the problem can be solved by adjusting the frequency of the PWM signal and increasing the duration of the high level. In another optional implementation, in this embodiment, the communication unit 11 can also first output a long high-level signal, and after activating the relay U1 to energize, output a PWM signal to control the relay U1, so as to improve the reliability of the receiver operation and stabilize the power supply status of the electrical appliance.
[0056] Furthermore, if Figure 4As shown, in an optional embodiment, the communication module 1 also includes: a voltage conversion unit 134, one end of the voltage conversion unit 134 is electrically connected to the connected target wire, and the other end of the voltage conversion unit 134 is electrically connected to the communication unit 11, and the voltage conversion unit 134 is used to adjust the voltage input via the connected target wire to supply power to the communication unit 11. The voltage conversion unit 134 includes an energy storage subunit, a power control subunit, and a feedback subunit. The energy storage subunit is electrically connected to the connected target wire. The energy storage subunit is also electrically connected to the communication unit 11 via the power control subunit and the feedback subunit. The power control subunit is electrically connected to the feedback subunit. The energy storage subunit is used to store the electric energy input through the connected target wire and output the electric energy to the power control subunit. The power control subunit is used to adjust the electric energy and output the adjusted electric energy to the feedback subunit. The feedback subunit is used to use the adjusted electric energy to power the communication unit 11 and send a feedback signal to the power control subunit so that the power control subunit adjusts the electric energy according to the feedback signal.
[0057] Specifically, the communication module 1 also includes: a surge current suppression unit, a surge voltage suppression unit, a rectification unit, a filtering unit and a peripheral circuit, wherein the target wires connected to the communication module 1 include a live wire L and a neutral wire N, the surge voltage suppression unit is connected in parallel between the live wire L and the neutral wire N, one end of the surge current suppression unit is connected to the neutral wire N, and the other end of the surge current suppression unit is connected to the voltage conversion unit 134 via the rectification unit and the filtering unit, and the peripheral circuit is electrically connected to the communication unit 11. Wherein, the rectifier unit includes two diodes D1 and D2 connected in series, the filter unit includes a capacitor C1, an inductor L1, and a resistor R1, one end of the inductor L1 connected in parallel with the resistor R1 is connected to the rectifier unit, and the other end of the inductor L1 connected in parallel with the resistor R1 is connected to the energy storage subunit, one end of the capacitor C1 is connected to the rectifier unit, and the other end of the capacitor C1 is connected to the live wire L, the energy storage subunit includes a capacitor C2, one end of the capacitor C2 is connected to the filter unit, and the other end of the capacitor C2 is connected to the live wire L, the power control subunit includes a power controller such as a PWM generator, and MOS tube Q1, the feedback subunit includes a diode D3, an inductor L3, and a capacitor C3, the drain of Q1 is connected to the energy storage subunit, the gate of Q1 is connected to one end of the power controller, the source of Q2 is connected to the cathode of the diode D3, the anode of the diode D3 is connected to one end of the inductor L3 via the capacitor C3, the other end of the inductor L3 is connected to the cathode of the diode D3, and the anode of the diode D3 is also connected to the live wire L; the other end of the power controller is connected between the inductor L3 and the capacitor C3, one end of the communication unit 11 is connected between the inductor L3 and the capacitor C3, and the communication unit 11 is also connected to the live wire L. In addition, the target wire connected to the communication module 1 may also include a connected neutral wire N, a control wire such as a first control wire OUT1, and a second control wire OUT2, and the corresponding energy storage switch 131 may include a relay 1 and a relay 2. The communication unit 11 is also connected to the energy storage switch 131 such as relay 1 and relay 2 via the power switch 132. One conductive contact of the relay such as relay 1 and relay 2 is connected to the live wire L. The other conductive contact of the relay is connected to the electrical appliance via the connected control wires such as OUT1 and OUT2. The electrical appliance is also connected to the connected neutral wire N to control the on and off of the power supply to the electrical appliance by the on and off between the two conductive contacts of the relay. Figure 4 In the example, the electrical appliance is taken as an electric lamp.
[0058] In this embodiment, power is supplied by taking electricity from the neutral and live wires, and a surge voltage suppression unit (such as a varistor) is connected in parallel between the neutral and live wires. When the voltage of the connected power grid is in the negative half cycle, after the current passes through the surge current suppression unit (such as a fuse resistor), the rectifier unit rectifies the input AC power into DC, and filters it through the filter unit to process the voltage pulse waveform rectified by the rectifier unit into a smooth DC waveform. The rear end of the filter unit is connected to a voltage conversion unit 134, which includes at least a switch tube (Q1), a current-type energy storage device (L2), a voltage-type energy storage device (C3), a power controller and a freewheeling diode (D3). The circuit controls the conduction of the switch tube Q1 through the pulse signal of the power controller, and the rear-end device reduces the high voltage (140V~380V) to the low voltage (3.3V). Exemplarily, when the pulse signal is at a high level, the switch tube Q1 is turned on, and the electric energy current stored in the energy storage subunit C2 flows through the switch tube Q1 to the inductor L2, and then supplies power to the capacitor C3 and the back-end communication unit 11 after passing through the inductor L2. When the pulse signal is at a high level, the power controller outputs a low level, and the switch tube Q1 is turned off. Due to the physical characteristics of the inductor, the current at both ends of the inductor L3 cannot change suddenly. The inductor L3 forms a loop through the diode D3 to continue to supply power to the back-end capacitor C3 and the communication unit 11, and transmits the back-end voltage to the power controller in real time through the voltage feedback line. The power controller compares the feedback voltage with the internal reference voltage and adjusts the frequency parameters of the output pulse to achieve the purpose of stabilizing the output voltage. After the output voltage is filtered by the capacitor C3, a stable 3.3V voltage is output, which is supplied to the wireless transmission circuit in the back-end communication unit 11 and the signal monitoring unit 12 for configuration and sending of wireless messages.
[0059] Furthermore, combined with Figure 4 and Figure 5As shown, in an optional embodiment, the peripheral circuit includes a trigger such as a first trigger S1 and a second trigger S2, and also includes indicator lights such as a first indicator LED1, a second indicator LED2, and a third indicator LED3, and the communication unit 11 is grounded via S1, S2, LED1, LED2, and LED3 respectively. The peripheral circuit also includes resistors R2 and R3. The communication module 1 in this embodiment also includes a circuit board; the communication unit 11, the signal monitoring unit 12, and the power taking unit 13 are all arranged on the circuit board, and the circuit board is also provided with triggers S1 and S2, which can be micro switches, for example. The circuit board is also provided with light-emitting parts, namely LED1, LED2, and LED3. For example, LED1 can be used to indicate the working state of the communication unit 11, such as the working state of WiFi in the communication unit 11, and LED2 and LED3 can be used to indicate the working states of two relays, such as relay 1 and relay 2, respectively. LED1, LED2, and LED3 can display the same or different light colors. When the control pin corresponding to the communication unit 11 outputs a high level, the forward current passes through the LED to the ground, and the LED is lit. When the control pin corresponding to the communication unit 11 outputs a low level, the potential difference between the two ends of the LED is equal, no current passes, and the LED is off. The trigger components S1 and S2 are pulled up and connected to the pins of the communication unit 11 through resistors R2 and R3. When the trigger components S1 or S2 are not pressed, the pin input level is high. When the trigger components S1 or S2 are pressed, the pin is connected to GND and the level on the pin is low. The communication unit 11 can detect whether the trigger components S1 or S2 are triggered by detecting the pin level state. For example, the trigger component S1 can be used to reset the WiFi of the communication unit 11, and the trigger component S2 can be used to configure the working mode switch of the receiver, such as the relay state switch. The communication unit 11 has a WiFi communication function and can be connected to a cloud server or terminal, and then the relay in the receiver can be remotely wirelessly switched through a terminal such as an APP on a mobile phone.
[0060] Furthermore, if Figure 6 As shown, in an optional embodiment, the signal monitoring unit 12 includes an antenna 121, an impedance matching network 122 and a wireless receiving subunit 123, the antenna 121 is electrically connected to the wireless receiving subunit 123 via the impedance matching network 122, and the wireless receiving subunit 123 is electrically connected to the communication unit 11; the wireless signal received by the antenna 121 is transmitted to the wireless receiving subunit 123 via the impedance matching network 122, and the wireless receiving subunit 123 pre-processes the wireless signal and sends it to the communication unit 11. The signal monitoring unit 12 also includes an anti-static electronic unit 124, and the anti-static electronic unit 124 is electrically connected to the antenna 121.
[0061] Specifically, the impedance matching network 122 includes an inductor L4, a capacitor C9, and a capacitor C8, and the anti-static electronic unit 124 includes a TVS diode D5, i.e., a transient voltage suppression diode, one end of the TVS diode D5 is connected to the antenna 121, and the other end is grounded. Since the antenna 121 receives various clutter signals and static voltages with a large voltage in addition to effective signals, in order to prevent the large voltage received by the antenna 121 from damaging the circuit components in the back end of the signal detection unit 12, such as the chip in the wireless receiving subunit 123, a TVS diode D5 is also provided in this embodiment, which can prevent the wireless receiving subunit 123 from being damaged by the large voltage received by the antenna 121.
[0062] The signal monitoring unit 12 may also include a filtering subunit composed of a capacitor C6, a capacitor C7, an inductor L3, and an inductor L5, so as to filter the wireless signal received by the antenna 121. The wireless receiving subunit 123 is connected to the antenna 121 via the inductor L3 and the inductor L4, one end of the capacitor C6 is connected to the wireless receiving subunit 123, the other end of the capacitor C6 is grounded, one end of the capacitor C7, the inductor L5, and the capacitor C8 is connected in parallel and connected between the inductors L3 and L4, the other end of the capacitor C7, the inductor L5, and the capacitor C8 is connected in parallel and connected to the ground, one end of the capacitor C9 is connected between the inductor L4 and the antenna 121, and the other end of the capacitor C9 is grounded. Specifically, when the antenna 121 captures a wireless signal such as an electromagnetic wave transmitted by the transmitter, it converts it into a guided wave. In order to solve the problem of impedance mismatch during power transmission, the microwave signals captured by the antenna, such as low-frequency and high-frequency microwave signals, can be transmitted to the load, namely the wireless receiving subunit 123. In this embodiment, the converted guided wave is transmitted to the wireless receiving subunit 123 after the impedance matching network 122 and filtering, so as to improve the power transmission performance of the wireless signal. The wireless receiving subunit 123 may be provided with a demodulation and analog-to-digital conversion circuit, which outputs the demodulated original signal to the communication unit 11 after a series of processing processes for the electromagnetic wave signal transmitted from the antenna 121. The communication unit 11 responds accordingly according to the received message information, such as sending a corresponding control signal to the power taking switch 132, thereby controlling the working state of the electrical appliance.
[0063] In the above embodiments, Figure 7As shown, the housing includes: a base 2, a first upper shell 3 and a second upper shell 4. The base 2 plays a role in fixing or supporting the components inside the receiver. The components inside the receiver may include, for example, various circuit units or circuit components on the communication module 1. The base 2 can be any structure or shape that can fix or support the components inside the receiver. For example, the base 2 can be provided with a card slot structure for fixing the components inside the receiver; for example, the base 2 can be provided with a receiving cavity, and some components of the receiver are installed inside the receiving cavity; for example, the base 2 can be a circular base 2 or a square base 2. At the same time, the base 2 can determine its own structure according to the external use environment. For example, as an external receiver, the base 2 can be provided with a mounting hole; as a built-in receiver, the base 2 may not be provided with a mounting hole.
[0064] The first upper shell 3 is detachably connected to the base 2; wherein the first upper shell 3 and the base 2 can be detachably connected by means of buckles or screws. For example, the first upper shell 3 can be provided with buckles, and the base 2 can be provided with slots. Through the cooperation of the buckles and the slots, the first upper shell 3 and the base 2 are connected together. In order to further improve the fixing effect, the number of buckles and slots can be set to multiple. The specific number, position and size of the buckles and slots can be determined according to actual conditions. A first accommodating cavity is formed between the first upper shell 3 and the base 2, and at least part of the communication module 1 is located in the first accommodating cavity. Among them, at least one of the first upper shell 3 and the base 2 includes a hollow accommodating cavity with openings facing each other, which is used to accommodate at least part of the communication module 1. In one embodiment, only the first upper shell 3 includes a first accommodating cavity opening in the direction of the base 2. In another embodiment, only the base 2 includes a first accommodating cavity opening in the direction of the first upper shell 3. In another embodiment, the first upper shell 3 may include a part of the accommodating cavity opening in the direction of the base 2, and the base 2 may include another part of the accommodating cavity opening in the direction of the first upper shell 3. After the first upper shell 3 and the base 2 are engaged, the part of the accommodating cavity and the other part of the accommodating cavity together form the first accommodating cavity. Those skilled in the art can understand that at least part of the communication module 1 can be placed horizontally or vertically in the first accommodating cavity.
[0065] The second upper shell 4 is detachably connected to the base 2, for example, the second upper shell 4 and the base 2 can be detachably connected by means of buckles or screws. A second accommodating cavity is formed between the second upper shell 4 and the base 2, and an end of the second upper shell 4 facing away from the first upper shell 3 and an end of the base 2 form an outlet 5 for connecting or disconnecting a target wire.
[0066] Compared with the existing receiver in which the upper shell is designed as an integral part, each time the target wire connected or connected to the receiver needs to be operated, such as wiring, fixing, disconnecting, and changing the wire, the entire upper shell needs to be opened, which will expose the entire communication module 1. Once the operation is improper, the circuit components such as chips in the communication module 1 will be damaged, which increases unnecessary risks. In this embodiment, the receiver has a first upper shell 3 and a second upper shell 4 that can be detachably connected to the base 2, respectively. The first accommodating cavity formed between the first upper shell 3 and the base 2 is used to accommodate at least part of the communication module 1, and the target wire connected or connected to the receiver is at least partially located in the second accommodating cavity formed between the second upper shell 4 and the base 2. In this embodiment, when operating the target wire, it is only necessary to remove the second upper shell 4 and perform corresponding operations on the target wire in the second accommodating cavity, without removing the first upper shell 3, and the entire communication module 1 will not be exposed, which not only improves the operating efficiency, but also reduces the risk of damage to the communication module 1 in the receiver.
[0067] Furthermore, if Figure 7 and Figure 8 As shown, in some embodiments, the receiver further includes a coupler 6; the coupler 6 is disposed between the base 2, the first upper shell 3, and the second upper shell 4 to couple the base 2, the first upper shell 3, and the second upper shell 4 into an integral structure. In this embodiment, the coupler 6 can generate an interaction force between the first upper shell 3 and the second upper shell 4, so that the base 2, the first upper shell 3, and the second upper shell 4 can be fixed together by means of the interaction force, that is, the base 2, the first upper shell 3, and the second upper shell 4 can be coupled into an integral structure by the coupler 6. In an optional embodiment, the coupler 6 can be disposed on the first upper shell 3, and the second upper shell 4 can generate an interaction force on the first upper shell 3 by applying a force to the coupler 6. In another optional embodiment, the coupler 6 can be disposed on the second upper shell 4, and the first upper shell 3 can generate an interaction force on the second upper shell 4 by applying a force to the coupler 6.
[0068] Furthermore, since the second upper shell 4 needs to be removed in order to perform corresponding operations on the target wire in the second accommodating cavity in this embodiment, in a preferred embodiment, the coupler 6 is arranged on the first upper shell 3 to facilitate the disassembly of the second upper shell 4. The following is an exemplary description using the arrangement of the coupler 6 on the first upper shell 3 as an example. The coupler 6 extends from one end of the first upper shell 3 facing the second upper shell 4; the first abutment portion 41 is provided on one side of the second upper shell 4 facing the base 2, and the coupler 6 includes a second abutment portion 61 matching the first abutment portion 41, and the first abutment portion 41 abuts against the second abutment portion 61, so that the second upper shell 4 presses the first upper shell 3 against the base 2 through the coupler 6. In an optional embodiment, the first abutting portion 41 may include a first abutting edge 411 extending from the second upper shell 4 toward the base 2, and the second abutting portion 61 may include a first pressing surface 611 extending from the first upper shell 3 toward the wire outlet 5. When the second upper shell 4 is fixed on the base 2, the first abutting edge 411 may abut against the first pressing surface 611, so that the second upper shell 4 presses the first upper shell 3 against the base 2 through the coupler 6.
[0069] Furthermore, in some embodiments, a second pressing surface 612 is also provided on an end of the coupler 6 away from the first upper shell 3, and a second abutting edge 412 matching the second pressing surface 612 is provided on the second upper shell 4 toward the base 2. When the second upper shell 4 is fixed on the base 2, it can abut against the second pressing surface 612 through the second abutting edge 412. It should be noted that the first pressing surface 611 may include side pressing surfaces 6111, 6112 extending from the first upper shell 3 toward the wire outlet 5 and arranged on both sides of the coupler 6, or a horizontal pressing surface 6113 extending from the first upper shell 3 toward the wire outlet 5 and arranged on the connecting plane between the coupler 6 and the first upper shell 3. In this embodiment, any one of the side pressing surfaces 6111, 6112 and the horizontal pressing surface 6113 can be set to achieve pressing. For example, when the horizontal pressing surface 6113 does not have a pressing effect with the first abutting edge 411, it may only have a dustproof effect to achieve the sealing of the connection between the first upper shell 3 and the second upper shell 4.
[0070] like Fig. 9As shown, in this embodiment, when the second upper shell 4 is fixed on the base 2, through the abutment between the first abutting edge 411 and the first pressing surface 611 such as the side pressing surface 6111, 6112 or the horizontal pressing surface 6113 and the abutment between the second abutting edge 412 and the second pressing surface 612, a force toward the base 2 can be applied to the coupler 6 at at least two different force positions, so that the first upper shell 3 can be pressed against the base 2 more stably through the coupler 6.
[0071] Furthermore, combined with Figure 8 and Fig.14 As shown, in some embodiments, the second upper shell 4 is provided with screw holes 103 and 104 at the first end A away from the first upper shell 3, and is provided with a second coupling connection portion at the second end B close to the first upper shell 3; the coupler 6 also includes a first coupling connection portion. In an optional embodiment, the first coupling connection portion includes a first slide groove 62 provided on opposite sides of the coupler 6; the second coupling connection portion includes a first sliding member 63 matching the first slide groove 62; wherein the first sliding member 63 is provided to cooperate with the first slide groove 62 to form the relative coupling relationship in which the second end B of the second upper shell 4 is slidably connected to the base 2 in the vertical direction. In addition, the first slide groove 62 can be an independent slide groove provided on the coupler 6, or a guide ridge 621 extending from the coupler 6, and the slide groove is formed by the guide ridge 621 and the main body of the first upper shell 3. The first sliding member 63 may be obtained by extending the second upper shell 4 toward the base 2, so that the first sliding member 63 is suitable for sliding in the vertical direction in cooperation with the first sliding groove 62, so that the second upper shell 4 can be quickly installed and disassembled by sliding in the vertical direction. In addition, in some embodiments, the first sliding groove 62 and the first sliding member 63 may be arranged in reverse, for example, the first coupling connection portion includes a second sliding member arranged on opposite sides of the coupler 6, and the second coupling connection portion includes a second sliding groove matching the second sliding member; wherein the second sliding member is arranged in the second sliding groove to form the relative coupling relationship in which the second end of the second upper shell 4 is slidably connected to the base 2 in the vertical direction.
[0072] The first end A of the second upper shell 4 is connected to the base 2 through screws corresponding to the screw holes 103 and 104, and the second end B is connected to the base 2 through the relative coupling relationship between the second coupling connection part and the first coupling connection part. In this embodiment, the second upper shell 4 can press the first upper shell 3 against the base 2 through the coupler 6 at the second end B close to the first upper shell 3, and the second upper shell 4 is connected to the base 2 through screws at a position away from the first end A of the first upper shell 3, that is, close to the outlet 5, so that the base 2, the first upper shell 3, the coupler 6 and the second upper shell 4 can be coupled into an integral structure. Since the first upper shell 3 can be fixed to the base 2 by screws at the first end A of the second upper shell 4 close to the outlet 5 in this embodiment, no additional fixing parts such as screws are required at the connection between the second upper shell 4 and the first upper shell 3, that is, no screws are required at the position close to the first upper shell 3, and the screws at the first end A are far away from the first upper shell 3, and are also far away from the electronic devices such as antennas located in the first accommodating cavity. This avoids the problem in the prior art that screws are set in the middle of the receiver to fix the upper shell, which causes the receiver to receive wireless signals and is interfered by the screws, thereby ensuring the stability of the receiver receiving signals. At the same time, the coupler 6 couples the first upper shell 3 and the second upper shell 4 into an integral structure, avoiding the appearance integrity of the receiver being affected by the screw connection at the middle of the receiver, making the overall appearance of the receiver beautiful and neat.
[0073] Furthermore, combined with Figures 9 to 14 As shown, in some embodiments, the communication module 1 also includes a circuit board 7; a third accommodating cavity 67 is formed between the coupler 6 and the base 2, and the third accommodating cavity is connected to the first accommodating cavity; a wiring structure 71 is provided on the circuit board 7, and the wiring structure 71 is used to electrically connect with the target wire 14 that is connected or connected; the wiring structure 71 is located in the third accommodating cavity 67; when the first upper shell 3 is connected to the base 2, the coupler 6 presses the circuit board 7 to the base 2 through the wiring structure 71, so as to couple the base 2, the first upper shell 3, the second upper shell 4, and the circuit board 7 into an integral structure. In this embodiment, the wiring structure 71 on the circuit board 7 is accommodated in the third accommodating cavity 67 of the coupler 6, so that when the first upper shell 3 is connected to the base 2, not only can the first upper shell 3 be fixed by the second upper shell 4 through the coupler 6, but the coupler 6 can also apply force to the wiring structure 71, thereby achieving the base 2, the first upper shell 3, the second upper shell 4, and the circuit board 7 being fixed together through the coupler 6, thereby improving the integrity and stability of the receiver.
[0074] Further, in some embodiments, the end of the coupler 6 facing the outlet 5 is provided with a plurality of wiring ports 64 for connecting or connecting the target wires 14. An isolation structure 65 is provided between any two adjacent wiring ports 64, and the isolation structure 65 can enable the target wires 14 in the two adjacent wiring ports 64 to meet different creepage distance requirements, thereby improving the safety of the receiver. Exemplarily, the isolation structure 65 enables the distance between the target wires 14 in the two adjacent wiring ports 64 to be greater than or equal to 1.5 mm.
[0075] Furthermore, in some embodiments, a wiring operation opening 66 is provided on the side of the coupler 6 facing away from the base 2, and a wiring operation terminal 711 is provided on the side of the wiring structure 71 facing away from the base 2, and the wiring operation terminal 711 is exposed at the wiring operation opening 66. Wherein, along the specified direction from the third end to the fourth end of the second upper shell 4, the specified direction can be understood as the horizontal direction, and the plane perpendicular to the specified direction is taken as the projection plane, then the projection plane can be understood as the projection plane in the vertical direction when the receiver is placed horizontally. Fig.11 As shown, the first projection pattern 712 of the second upper shell 4 on the projection surface covers the second projection pattern 713 of the wiring operation opening 66 on the projection surface, so that when the second upper shell 4 is connected to the base 2, the second upper shell 4 covers the wiring operation opening 66, thereby protecting the wiring operation terminal 711 on the wiring structure 71, avoiding the wiring operation terminal 711 in the receiver from being exposed to the surface, and improving the safety of the receiver. When the second upper shell 4 is disassembled from the base 2, the wiring operation opening 66 is set in an exposed state to facilitate user operation when the user needs to operate the wiring operation terminal 711. In summary, in this embodiment, the receiver has a wiring operation terminal 711, and the second upper shell 4 can be easily installed or disassembled to achieve protection and operation of the wiring operation terminal 711, so that the receiver can be compatible with the requirements of built-in installation and external installation.
[0076] Furthermore, if Fig. 9As shown, in some embodiments, the base 2 is provided with a support portion 21 on the side facing the first upper shell 3, which is used to support the circuit board 7, so that a fourth accommodating cavity 22 is formed between the circuit board 7 and the base 2, and a fifth accommodating cavity 23 is formed between the circuit board 7 and the first upper shell 3; the circuit board 7 is provided with circuit components in the fourth accommodating cavity 22 and the fifth accommodating cavity 23. Among them, the support portion 21 can be one or more, and its position can be set in the middle or around the base 2, which is not limited here. In this embodiment, circuit components are set on both the front and back sides of the circuit board 7, which can not only reduce the volume of the receiver, but also the circuit components with larger heat generation on the circuit board 7 can be set on the front and back sides of the circuit board 7 respectively to dissipate heat separately, which is conducive to reducing the temperature of the receiver when it is working.
[0077] Further, in some embodiments, the antenna unit includes a spring antenna 72; the circuit board 7 is provided with the spring antenna 72 in the fifth accommodating cavity 23; the first upper shell 3 is provided with a limiting protrusion 31 corresponding to the spring antenna 72 on the side facing the bottom shell, and the limiting protrusion 31 is inserted into the spring antenna 72 to limit the movement of the spring antenna 72. In this embodiment, the antenna adopts a spring antenna 72, and a limiting protrusion 31 is provided to fix the position of the spring antenna 72 to prevent the spring antenna 72 from tilting left and right. Compared with the uncontrollable position of the wire antenna, the position of the spring antenna 72 in this embodiment is controllable and can be installed in the shell, so that the receiver meets the requirements of external installation.
[0078] Further, in some embodiments, the receiver further includes a trigger 73, for example, the trigger 73 can be set as a micro switch, and the number of the trigger 73 can be set according to the actual application. The trigger 73 is electrically connected to the communication module 1, for example, the trigger 73 is electrically connected to the communication unit 11, so as to output a trigger signal to the communication unit 11 in response to external control. In this embodiment, the trigger 73 is arranged at the end of the circuit board 7 opposite to the wiring structure 71, that is, the trigger 73 is located on the circuit board 7 at an end away from the wiring structure 71. Since the target wire 14 connected to the wiring structure 71 may be a mains power supply, that is, a strong power supply, therefore, in this embodiment, the trigger 73 is set at a position away from the strong power supply to avoid the user from directly or indirectly contacting the strong power supply when the trigger 73 is touched, thereby improving the safety of the receiver.
[0079] Further, in some embodiments, a button hole 32 is provided on the first upper shell 3, a trigger member 73 whose position matches the button hole 32 is provided on the circuit board 7, and a guide slot 33 connected to the button hole 32 is extended from one side of the first upper shell 3 toward the trigger member 73; the receiver further comprises at least one button 8 matching the guide slot 33; illustratively, the button 8 is in the form of a guide column, the button 8 passes through and is limited in the guide slot 33, wherein one end of the button 8 is exposed to the outer surface of the first upper shell 3, and the other end is located at a corresponding position close to the trigger member 73, and can trigger the trigger member 73 in response to the external force control transmitted by one end of the button 8. The guide slot 33 extends a limit buckle 331 in the direction close to the trigger member 73, and a limit portion 81 matching the limit buckle 331 is provided on the button 8, and the limit portion 81 cooperates with the limit buckle 331 to limit the button 8. The button 8 needs to be installed in the guide groove 33 before the base 2 and the first upper shell 3 are connected. After the base 2 and the first upper shell 3 are connected, the button 8 can move in response to the user's control force on the outer surface of the first upper shell 3. The button 8 moves downward along the guide groove 33 to touch the corresponding trigger member 73, and then outputs a trigger signal to the communication unit. At the same time, the button 8 is reset to the outer surface of the first upper shell 3 in response to the reset force of the trigger member 73, and is limited by the cooperation between the limit portion 81 and the limit buckle 331, so that the button 8 will not slide out from the outer surface of the first upper shell 3.
[0080] Furthermore, in some embodiments, a light-emitting member 74 is also provided on the circuit board 7, for example, the light-emitting member 74 may be an LED, and the number and position of the light-emitting member 74 may be set according to the actual application. The light-emitting member 74 is electrically connected to the communication module 1, for example, the trigger member 73 is electrically connected to the communication unit 11, so as to emit light of a specified color in response to a signal emitted by the communication unit 11. At least one light-transmitting through hole 34 is provided on the first upper shell 3, and the first upper shell 3 extends a light-guiding channel 35 toward the light-emitting member 74 in the fifth accommodating cavity 23, one end of the light-guiding channel 35 is connected to the light-transmitting through hole 34, and the other end surrounds the light-emitting member 74, so as to guide the light to the light-transmitting through hole 34 via the light-guiding channel 35 when the light-emitting member 74 emits light. Among them, reflective materials may be arranged around the light guiding channel 35 to reflect the light emitted by the light emitting component 74 to the light-transmitting through hole 34 for display. The light guiding channel 35 may also include ordinary shading materials to avoid scattering of light emitted by the light emitting component 74 and guide the light emitted by the light emitting component 74 to the light-transmitting through hole 34 for display.
[0081] Furthermore, in some embodiments, the inner surface of the first upper shell 3 facing the base 2 is also provided with an anti-rib 36, and the number and position of the anti-rib 36 can be set according to actual needs. For example, four anti-ribs 36 can be arranged around the first upper shell 3 to prevent the shell from deforming and making it difficult to disassemble, so as to fix the first upper shell 3 on the base 2.
[0082] Furthermore, combined with Figures 14 to 17 As shown, in some embodiments, the second upper shell 4 forms a wiring channel 9 for the target wire 14 to pass through in a bent state between one end A near the wire outlet 5 and the base 2. In order to ensure the reliability of the receiver and the safety of the external installation, the target wire 14 connected to the receiver needs to meet a certain amount of tension. For example, when the receiver is installed externally, the target wire 14 connected to the receiver needs to pass a 20N tension test requirement. Therefore, in this embodiment, a wiring channel 9 is formed between the end of the second upper shell 4 close to the wire outlet 5 and the base 2, and the target wire 14 passes through the wiring channel 9 in a bent state. For example, when matched with a screw at the end of the second upper shell 4 close to the wire outlet 5, the target wire 14 is bent into a V-shape, an S-shape, etc. in the wiring channel 9. In this way, compared with the existing wire pressing structure that only directly fixes or applies force to the wire itself of the target wire 14, such as only applying force in the horizontal direction to clamp the target wire 14, when the target wire 14 is subjected to external tension, as long as the tension is greater than the force clamping the target wire 14, the target wire 14 can be pulled out from the wiring structure 71. In the present embodiment, when pulling the target wire 14, the pulling force not only needs to be greater than the clamping force on the target wire 14, but also needs to overcome the force generated by the bending deformation of the target wire 14, so that the pulling force that the target wire 14 in the receiver can withstand is significantly enhanced, so that the receiver can meet the test requirements of a larger pulling force such as 20N, meet the need for the receiver to withstand a certain pulling force in some external installation environments, and improve the reliability and safety of the receiver.
[0083] Further, in some embodiments, at least one first crimping piece is provided on one side of the second upper shell 4 facing the base 2, and at least one first crimping groove matching the first crimping piece is provided on one side of the base 2 facing the second upper shell 4, so as to form the wiring channel 9 between the first crimping piece and the first crimping groove. The first crimping piece can be a first crimping portion 42 obtained by extending the second upper shell 4 in the direction toward the base 2, and one end of the first crimping portion 42 used for crimping can be a plane or a serrated surface, and the first crimping groove includes at least two protrusions (431, 432) extending from the base 2 toward the second upper shell 4, and the first crimping groove is formed between any two adjacent protrusions (431, 432), and the extension direction of the first crimping portion 42 in the vertical direction is located between any two adjacent protrusions (431, 432). In this way, when the target wire 14 is connected or connected through the outlet 5, the first wire crimping piece and the first wire crimping groove can form a wiring channel 9 for the target wire 14 to pass through in a bent state. In addition, in some embodiments, the first wire crimping piece and the first wire crimping groove can be set in reverse, for example, at least one first wire crimping groove is set on the side of the second upper shell 4 facing the base 2, and at least one first wire crimping piece matching the first wire crimping groove is set on the side of the base 2 facing the second upper shell 4, so as to form the wiring channel 9 between the first wire crimping piece and the first wire crimping groove.
[0084] Specifically, Fig.17As shown, the first wire crimping member forms a first wire crimping end 421 of the first wire crimping member at an end close to the first wire crimping groove; the first wire crimping groove forms a second wire crimping end 422 of the first wire crimping groove at an end close to the side wall of the first wire crimping member; wherein the vertical distance between the first wire crimping end 421 of the first wire crimping member and the second wire crimping end 422 of the first wire crimping groove is smaller than the diameter of the target wire 14, so that the target wire 14 is bent and deformed when it is connected to or connected from the communication module 1 through the wiring channel 9. In this embodiment, the gap reserved in the vertical direction in the wiring channel 9 formed by the first wire crimping member and the first wire crimping groove is small, so that the target wire 14 cannot maintain a horizontal direction in the wiring channel 9 when it is connected or connected, and the first wire crimping member squeezes part of the target wire 14 into the first wire crimping groove, and the target wire 14 forms a V-shaped bending deformation in the first wire crimping groove. In this way, compared with the existing wire pressing structure that only directly fixes the target wire 14 itself, the target wire 14 in this embodiment forms a V-shaped bending deformation in the first wire pressing groove. When an external force pulls the target wire 14, the pulling force must also overcome the force generated by the bending deformation of the target wire 14 in order to directly apply pulling force to the connection between the target wire 14 and the communication module 1. For example, it is necessary to overcome the force generated by straightening the V-shaped bend, so that the pulling force that the target wire 14 in the receiver can withstand is enhanced, thereby improving the reliability and safety of the receiver.
[0085] Further, a second crimping piece is provided on the side of the first crimping piece close to the communication module 1, and the extension direction of the second crimping piece is consistent with that of the first crimping piece; the second crimping piece forms a third crimping end 441 of the second crimping piece at the end close to the first crimping groove; the distance between the first crimping end 421 of the first crimping piece and the second crimping end 422 of the first crimping groove is smaller than the distance between the third crimping end 441 of the second crimping piece and the second crimping end 422 of the first crimping groove. In this embodiment, the second crimping piece can be a second crimping portion 44 obtained by extending the second upper shell 4 in the direction toward the base 2, and the crimping end of the second crimping portion 44 can be a plane or a serrated surface. After the target wire 14 forms a V-shaped bending deformation in the first wire crimping groove, it still needs to be connected to the communication module 1 such as the wiring structure 71. Since the angle between the target wire 14 and the wiring structure 71 is relatively large after the V-shaped bending deformation, if the target wire 14 is directly connected to the wiring structure 71 after the V-shaped bending deformation, the connection between the target wire 14 and the wiring structure 71 will be subjected to greater force, which is not conducive to the stable connection between the target wire 14 and the wiring structure 71. Therefore, in this embodiment, a second wire pressing member such as a second wire pressing portion 44 is arranged between the first wire pressing member such as the first wire pressing portion 42 and the wiring structure 71. The target wire 14 is also subjected to the wire pressing force of the second wire pressing portion 44 after undergoing V-shaped bending deformation, wherein the direction of the wire pressing force of the second wire pressing portion 44 is consistent with the direction of the wire pressing force of the first wire pressing portion 42, so that when the target wire 14 is connected to the wiring structure 71 after the wire pressing action of the second wire pressing portion 44, the angle between the target wire 14 and the wiring structure 71 tends to be gentle, so as to reduce the force at the connection between the target wire 14 and the wiring structure 71, which is beneficial to the stable connection between the target wire 14 and the wiring structure 71, and further improves the reliability of the receiver.
[0086] Furthermore, in some embodiments, at least one limiting clamping portion 45 is provided on two opposite sides of the second upper shell 4 facing the base 2, for limiting the second upper shell 4 and clamping it to a corresponding position of the base 2. When the second upper shell 4 is connected to the base 2, the vertical extension direction of the first wire pressing portion 42 is located between any two adjacent protrusions 431, 432, so as to form a wiring channel 9 for the target wire 14 to pass through in a bent state.
[0087] Further, the second upper shell 4 is connected to the base 2 by two screws 101 and 102 arranged oppositely; the first wire pressing member is arranged between the mounting holes 103 and 104 corresponding to the two screws, and its extension direction coincides with the line connecting the centers of the two mounting holes. For example, the second upper shell 4 is provided with a first mounting hole 103 and a second mounting hole 104, the base 2 is provided with a third mounting hole 105 and a fourth mounting hole 106, the first screw 101 passes through and is installed in the first mounting hole 103 and the third mounting hole 105 in turn, and the second screw 102 passes through and is installed in the second mounting hole 104 and the fourth mounting hole 106 in turn, so that the second upper shell 4 is fixed to the base 2. In this embodiment, the second upper shell 4 is fixed to the base 2 by using a screw arranged at the end of the second upper shell 4 near the outlet 5, and at the same time, the force of the screw is used to cooperate with the first wire pressing member and the first wire pressing groove to achieve the bending deformation of the target wire 14. And because the direction of the force applied by the screw on the target wire 14 is the direction of the line connecting the centers of the two mounting holes, in this embodiment, the first wire pressing member is arranged between the first mounting hole 103 and the second mounting hole 104, so that the force applied by the screw is consistent with the force applied by the first wire pressing member on the target wire 14, so as to prevent the second upper shell 4 from tilting due to inconsistent force during wire pressing.
[0088] Furthermore, a fifth mounting hole 107 and a sixth mounting hole 108 are provided on the base 2, and the shell is fixed to the outside through the fifth mounting hole 107 and the sixth mounting hole 108 to achieve external installation of the receiver.
[0089] Furthermore, an embodiment of the present invention also proposes an electronic device, including the receiver as described above and an electrical appliance, wherein the receiver is electrically connected to the electrical appliance, and after the receiver detects an external signal, the receiver controls the working state of the electrical appliance according to the external signal. For example, the electronic device may be a smart curtain, a garbage disposer, etc., which integrates the functions of the above-mentioned receiver and can be wirelessly controlled. Among them, the circuit and structure of the receiver in the electronic device and the process of controlling the working state of the electrical appliance refer to the above-mentioned embodiment and are not described in detail here.
