Abstract
Description
Technical Field
[0001] The present invention relates to the field of intelligent control technology, and in particular to a receiver and electronic equipment. Background Art
[0002] With the development of intelligence, intelligent control of electrical appliances has become a new demand. In the prior art, intelligent control of electrical appliances is generally achieved through a receiver, that is, the receiver receives signals to control the power supply of the electrical appliance and thus achieves intelligent control of the electrical appliance. Summary of the Invention
[0003] The present invention provides a receiver and an electronic device to solve the problems in the prior art.
[0004] According to a first aspect of the present invention, there is provided a receiver, comprising:
[0005] Base:
[0006] a first upper shell, the first upper shell being detachably connected to the base and forming a first accommodating cavity between the first upper shell and the base;
[0007] a communication module, the communication module being configured to monitor external signals and control the operating state of an electrical appliance connected to the communication module based on the monitored external signals, wherein at least a portion of the communication module is located within the first accommodating cavity;
[0008] a second upper shell, the second upper shell being detachably connected to the base and forming a second accommodating cavity between the second upper shell and the base, wherein an end of the second upper shell facing away from the first upper shell and an end of the base form an outlet for receiving or receiving a target wire;
[0009] Among them, the second upper shell forms a wiring channel for the target wire to pass through in a bent state between one end close to the wire outlet and the base. The target wire is bent through the wiring channel to place the end of the target wire in the second accommodating cavity and is connected to the communication module in the second accommodating cavity. The target wire can still remain connected to the communication module when subjected to a tensile force greater than or equal to 20N.
[0010] According to a second aspect of the present invention, an electronic device is provided, comprising the receiver as described above and an electrical appliance, wherein the receiver is electrically connected to the electrical appliance, and after detecting an external signal, the receiver controls the working state of the electrical appliance according to the external signal.
[0011] The receiver and electronic device provided by the present invention utilize a detachable connection between the first upper shell, the second upper shell, and the base. This eliminates the need to open the entire upper shell each time a target wire needs to be connected or disconnected from the receiver, thereby exposing the entire communication module and preventing damage to the circuit components in the communication module. Furthermore, a wiring channel for the target wire to pass through in a bent state is formed between the second upper shell at one end near the wire outlet and the base. Compared to existing methods that only directly fix or apply force to the target wire, such as clamping the target wire horizontally, when the target wire is subjected to external tension, the target wire can be pulled out of the wiring structure as long as the tension is greater than the force clamping the target wire horizontally. In the present invention, when pulling the target wire, the tension not only needs to be greater than the clamping force on the target wire, but also needs to overcome the force generated by the bending deformation of the target wire. This significantly enhances the tension that the target wire in the receiver can withstand. When the wire is pulled by external force, it is less likely to cause the wire to detach from the wiring port, thereby improving the reliability and safety of the receiver.

[0036] In the description of the present invention, unless otherwise specified or limited, the term "connection" and other terms should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] The following specific embodiments are used to describe the technical solution of the present invention in detail. 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 housing (not shown in the figure) and a communication module 1, wherein the housing has a receiving cavity; the communication module 1 is used to connect to a target wire (not shown in the figure) to be 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 neutral wire N of the mains power supply, or the live wire L and 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, or 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 conductor. For example, in an optional embodiment, the mains electricity flowing through the target conductor is rectified, filtered, and stepped down, and then outputs a voltage to the communication unit 11, thereby powering the communication unit 11. The power supply unit 13 is electrically connected to the communication unit 11 so that it can be switched on and off under the control of the communication unit 11. The power supply unit 13 is electrically connected to an electrical appliance to control the operating state of the appliance, such as the power supply state. The electrical appliance may be a lamp, smart curtain, or other electrical device. 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 or wireless signals, so that the communication unit 11 can control the on and off state of the power supply unit 13 based on the external signals detected by the signal monitoring unit 12, thereby controlling the operating state of the electrical appliance connected to the power supply unit 13.
[0040] Furthermore, the power extraction unit 13 includes an energy storage switch 131 and a power extraction switch 132; the energy storage switch 131 is operably connected to the power extraction switch 132, for example, the energy storage switch 131 can be directly or indirectly electrically connected to the power extraction switch 132, and is configured to be controlled to be turned on or off by the power extraction switch 132. The power extraction switch 132 is operably connected to the communication unit 11, for example, the power extraction switch 132 can be directly or indirectly electrically connected to the communication unit 11, and is configured to be suitable for receiving the control signal of the communication unit 11, so that when the electrical appliance is in a working state, the energy storage switch 131 is continuously connected in a first time period to form a first power supply stage, and is continuously disconnected 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, in this embodiment, the duration of the first time period is set to be greater than or equal to the duration of the second time period.
[0041] Among them, the energy storage switch 131 has an energy storage function, 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 maintain operation for a period of time. For example, 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 during 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 during the first time period. For example, when the energy storage switch 131 controls the electrical appliance to be in a working state, i.e., a power supply state, it stores a certain amount of energy itself, which is considered to be able to control the electrical appliance to be in a working state during the first power supply phase of the energy storage switch 131. After the power switch 132 receives the control signal of the communication unit 11, it is continuously disconnected during the second time period. In this case, 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 during 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 during the second time period, which is considered to be able to control the electrical appliance to be in a working state during the second power supply phase of the energy storage switch 131. 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 taken into account that in actual applications, the electrical appliances may be in an operating state, i.e., a power supply state, for a long time. If the receiver is also in a continuous high-power operation to support the working state of the electrical appliances, the long-term continuous high-power operation of the receiver will cause its power consumption to be too high. Therefore, in this embodiment, after receiving an external signal, the communication unit 11 of the receiver sends a control signal to the power switch 132. According to the control signal, the power switch 132 is continuously turned on during a first period to form a first power supply stage of the energy storage switch 131, and is continuously turned off during a second period to form a second power supply stage of the energy storage switch 131; the electrical appliances are in an operating state during both the first power supply stage and the second power supply stage. Because the energy storage switch 131 in the receiver can still keep the electrical appliances in an operating state when the power switch 132 is turned off, that is, the receiver does not need to be in a continuously connected high-power 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] Furthermore, 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 by being turned on and off by the power switch 132, taking into account 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 implement the subsequent delay control function. Otherwise, if such energy storage switches 131 are directly delayed, the electrical appliance may not be able to remain in a working state, i.e., it cannot be continuously powered. Therefore, in this embodiment, after the communication unit 11 receives the external signal detected by the signal monitoring unit 12, it first sends a first control signal to the power switch 132; after receiving the first control signal, the power switch 132 is continuously turned on and supplies power to the energy storage switch 131. After receiving the energy from the power switch 132, the energy storage switch 131 is activated to control the electrical appliance to be in a working state, i.e., a power supply state, and is considered to be able to control the electrical appliance to be in a working state during the third power supply stage of the energy storage switch 131. 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, the first control signal can be a low-level signal that lasts for a third time period; if a high-level signal can turn on the power switch 132, the first control signal can be a high-level signal that lasts for a third time period. 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 connected to form a third power supply stage within the third time period, 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 within the third time period, the energy storage switch 131 receives energy from the power supply switch 132 and is activated to control the electrical appliance to be in a working state, i.e., a power supply state, which is conducive to the subsequent stable delay control of the working state of the electrical appliance by the energy storage switch 131, thereby improving the reliability of the receiver operation and avoiding the occurrence of unstable power supply to the electrical appliance electrically connected to the receiver.
[0047] Furthermore, in some embodiments, after the communication unit 11 sends a first control signal to the power switch 132 during the third time period to activate the energy storage switch 131's control of the electrical appliance's operating state, it may then send a second control signal to the power switch 132, causing the power switch 132 to receive the second control signal and, when the electrical appliance is in operation, to be continuously connected during the first time period to form a first power supply phase for the energy storage switch 131, and to be continuously disconnected during the second time period to form a second power supply phase for the energy storage switch 131. Thus, in this embodiment, after ensuring that the energy storage switch 131 is activated to control the electrical appliance in operation, during the first time period, the power switch 132 is connected to supply energy to the energy storage switch 131, allowing the energy storage switch 131 to control the electrical appliance in operation based on the energy supply. During the second time period, the power switch 132 is continuously disconnected, allowing the energy storage switch 131 to continue controlling the electrical appliance in operation using its 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 a working state, that is, the receiver does not need to be in a high-power consumption state that is always connected, 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 connected in a first time period to form the first power supply stage of the energy storage switch 131, and then continuously disconnected in a 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 a second time period to form the second power supply stage of the energy storage switch 131, and then continuously connected 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 phase and the second power supply phase of the energy storage switch 131 are not limited to a manner of cycling 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 ensure that the energy storage switch 131 stably delays the working state of the electrical appliance, while also keeping the power consumption of the receiver at a low level.
[0049] Furthermore, if Figure 2As shown, in some embodiments, the energy storage switch 131 includes an energy storage portion 1311 and at least one magnetically controlled electrode pair; the magnetically controlled electrode pair is electrically connected to the electrical appliance; the magnetically controlled electrode pair includes two conductive contacts 1312 and 1313. For example, the two conductive contacts 1312 and 1313 of the magnetically controlled electrode pair can be electrically connected to the two ends of the electrical appliance, respectively, or one of the two conductive contacts 1312 and 1313 of the magnetically controlled electrode pair is electrically connected to a target conductor such as a live wire L, and the other conductive contact 1312 is electrically connected to the electrical appliance via a 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 magnetic control electrode pair are connected, the electrical appliance is powered; if the two conductive contacts 1312 and 1313 in the magnetic control 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 magnetic control 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 magnetic control 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 coil 13112 in the energy storage unit 1311. The energy storage switch 131 can continue to operate for a period of time during 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 electrical energy in the coil 13112 in the energy storage unit does not disappear instantly. Within a specified time, the combination of the iron core 13111 and coil 13112 in the energy storage unit 1311 still has a certain magnetic attraction. 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, thereby ensuring that the electrical appliance can still be controlled to remain in an operating state after the power switch 132 is disconnected.Moreover, by simply controlling the duration of the power switch 132 being disconnected, that is, the duration of the second period being less than or equal to the specified time, 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 thus control the electrical appliance to be in an operating state after the power switch 132 is disconnected. Subsequently, the power switch 132 is turned on to supply energy to the energy storage unit 1311 to provide magnetic attraction. In this way, it can be ensured that the electrical appliance can be kept in an operating state whether the power switch 132 is disconnected or turned on. 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 supply unit 13 further includes a discharge subunit 133, which is electrically connected between the two ends of the coil 13112 and is configured to short-circuit the coil 13112 during at least a portion of the second power supply phase. Since the coil 13112 in the energy storage unit 1311 will have a high reverse voltage at the moment of power failure when the power supply switch 132 is disconnected, this reverse voltage is likely to damage the power supply 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 to release the reverse voltage through the discharge path formed by the discharge subunit 133 when the reverse voltage is generated, without damaging the power supply switch 132.
[0051] Furthermore, if Figure 3 As shown, in an optional embodiment, 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, thereby forming a discharge path for the energy storage switch 131 during the second time period. The power switch 132 may include a switching transistor, such as a MOS transistor or a transistor. In this embodiment, the power switch 132 includes a transistor Q2 as an example.
[0052] Specifically, the power switch 132 may also include a resistor voltage divider circuit, such as resistors R10, R12, and R14 in the figure. Since the coil of the relay U1 will have a reverse voltage at the moment of power failure, this reverse voltage is relatively high, possibly several times higher than the voltage of the DC power supply, and this reverse voltage is likely to burn out the transistor. Therefore, in this embodiment, a diode D7 is provided to provide a discharge path for the reverse voltage at the moment of power failure of the relay U1, effectively protecting the driving transistor Q2. The power switch 132 may also include an indicator LED4 to indicate whether the power switch 132 is controlled by the on or off state of the communication unit 11, that is, the on-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, and 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] Relay U1 includes a magnetically controlled electrode pair, each comprising two conductive contacts, which may be a movable contact and a stationary contact that mate with an armature. When the control signal from communication unit 11 is high, transistor Q2 conducts, energizing the coil wound around the iron core of relay U1. Current flows through the coil, and due to the magnetic effect of the current, the coil of relay U1 becomes magnetic. Electromagnetic force pulls the armature toward the iron core, overcoming the pull of the return spring. This causes the movable contact of the armature to engage with the stationary contact (normally open contact). This activates the power supply path of the electrical appliance electrically connected to the contacts, energizing the appliance.
[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, releasing the moving contact and the original static contact (normally closed contact), 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, if the communication unit 11 continuously emits a high-level control signal, transistor Q2 will remain conducting, causing the coil of relay U1 to operate for extended periods of time. This will result in high power consumption and increased temperature of the coil of relay U1, adversely affecting the lifespan and safety of the receiver. Therefore, in this embodiment, the control signal emitted by the communication unit 11 can be a pulse width modulation (PWM) signal, the frequency of which can be set according to actual needs. When the PWM signal emitted by the communication unit 11 is high, relay U1 is energized. When the high-level signal ceases, transistor Q2 operates in the cutoff region. During this period, the current in the coil of relay U1 does not disappear instantly. For a certain period of time, relay U1 remains magnetic and can remain energized. Simply setting the low-level duration of the PWM signal to less than the demagnetization time of relay U1 ensures that relay U1 remains continuously energized. Therefore, in this embodiment, when controlling the electrical appliance in the power supply state, the coil of relay U1 does not need to remain in operation for extended periods of time, effectively reducing power consumption and the temperature of the coil of 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 attract, resulting in unstable power supply status of the electrical appliance. In an optional embodiment, the problem can be solved by adjusting the frequency of the PWM signal and increasing the duration of the high level. In another optional embodiment, in this embodiment, the communication unit 11 can also first output a long high-level signal, and after activating the relay U1 to attract, output the PWM signal to control the relay U1, so as to improve the reliability of the receiver's 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 through 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: an inrush current suppression unit, a surge voltage suppression unit, a rectifier unit, a filter 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 inrush current suppression unit is connected to the neutral wire N, and the other end of the inrush current suppression unit is connected to the voltage conversion unit 134 via the rectifier unit and the filter 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 and the resistor R1 being connected in parallel is connected to the rectifier unit, and the other end of the inductor L1 and the resistor R1 being connected in parallel 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 transistor 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 diode D3, the anode of diode D3 is connected to one end of inductor L3 via capacitor C3, the other end of inductor L3 is connected to the cathode of diode D3, and the anode of diode D3 is also connected to the live wire L. The other end of the power controller is connected between the inductor L3 and capacitor C3. One end of the communication unit 11 is connected between the inductor L3 and capacitor C3, and the communication unit 11 is also connected to the live wire L. In addition, the target wires connected to the communication module 1 may also include a connected neutral wire N and control wires such as a first control wire OUT1 and a second control wire OUT2. The corresponding energy storage switch 131 may include relay 1 and 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, and the other conductive contact of the relay is connected to the electrical appliance via the control line such as OUT1 and OUT2. The electrical appliance is also connected to the neutral line N, so that the power supply to the electrical appliance is controlled by the on-off between the two conductive contacts of the relay. Figure 4 In the example, the electrical appliance is an electric lamp.
[0058] In this embodiment, power is supplied by taking power from the neutral and live wires. A surge voltage suppression unit (e.g., a varistor) is connected in parallel between the neutral and live wires. When the connected grid voltage is in the negative half cycle, the current passes through the surge current suppression unit (e.g., a fuse resistor). The rectifier unit rectifies the input AC power into DC power, which is then filtered by the filter unit to process the voltage pulse waveform rectified by the rectifier unit into a smooth DC waveform. The filter unit is connected to a voltage conversion unit 134 at the rear end, 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 a pulse signal from the power controller, and the rear-end device reduces the high voltage (140V to 380V) to a low voltage (3.3V). For example, when the pulse signal is high, the switch Q1 is turned on, and the electric energy current stored in the energy storage subunit C2 flows through the switch Q1 to the inductor L2, and then through the inductor L2 to power the capacitor C3 and the back-end communication unit 11. When the pulse signal is high, the power controller output is low, and the switch Q1 is turned off. Due to the physical characteristics of the inductor, the current across the inductor L3 cannot change suddenly. The inductor L3 forms a loop through the diode D3 to continue to power 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 wireless messages.
[0059] Further, 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. 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 supply unit 13 are all arranged on the circuit board. The circuit board is also provided with triggers S1 and S2, which can be, for example, micro switches. The circuit board is also provided with light-emitting components, namely LED1, LED2, and LED3. For example, LED1 can be used to indicate the working status of the communication unit 11, such as the working status of WiFi in the communication unit 11. LED2 and LED3 can be used to indicate the working status 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, a forward current flows 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 flows, and the LED goes out. 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 component S1 or S2 is not pressed, the pin input level is high. When the trigger component S1 or S2 is pressed, the pin is connected to GND, and the level on the pin is low. The communication unit 11 can detect whether the trigger component S1 or S2 is triggered by detecting the pin level status. 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 status 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 on and off 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 then sends it to the communication unit 11. The signal monitoring unit 12 also includes an anti-static electronic unit 124, which 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. The anti-static electronic unit 124 includes a TVS diode D5, i.e., a transient voltage suppressor 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 not only valid signals but also various clutter signals and high-voltage static electricity, in order to prevent the high 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, the TVS diode D5 is also provided in this embodiment. This can prevent the wireless receiving subunit 123 from being damaged by the high 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 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 between the inductors L3 and L4, the other end of the capacitor C7, the inductor L5, and the capacitor C8 is grounded, 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, so that 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 sub-unit 123, in this embodiment, the converted guided wave is passed through the impedance matching network 122 and filtered before being transmitted to the wireless receiving sub-unit 123 to improve the power transmission performance of the wireless signal. The wireless receiving sub-unit 123 may be provided with a demodulation and analog-to-digital conversion circuit, which outputs the demodulated original signal of the electromagnetic wave signal transmitted from the antenna 121 to the communication unit 11 after a series of processing steps. The communication unit 11 responds accordingly based on the received message information, such as sending a corresponding control signal to the power 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 serves to secure or support the components within the receiver. For example, the components within the receiver may include various circuit units or circuit components on the communication module 1. The base 2 may be of any structure or shape that can secure or support the components within the receiver. For example, the base 2 may be provided with a slot structure for securing the components within the receiver. For example, the base 2 may be provided with a receiving cavity for mounting some of the components within the cavity. For example, the base 2 may be circular or square. The structure of the base 2 may also be determined based on the external usage environment. For example, as an external receiver, the base 2 may be provided with mounting holes. As a built-in receiver, the base 2 may not be provided with mounting holes.
[0064] The first upper shell 3 is detachably connected to the base 2. The first upper shell 3 and the base 2 can be detachably connected using clips or screws. For example, the first upper shell 3 can be provided with clips, and the base 2 can be provided with slots. The clips and slots cooperate to connect the first upper shell 3 and the base 2. To further enhance the securing effect, multiple clips and slots can be provided. The specific number, location, and size of the clips and slots can be determined based on actual conditions. A first accommodating cavity is formed between the first upper shell 3 and the base 2. At least a portion of the communication module 1 is located within the first accommodating cavity. At least one of the first upper shell 3 and the base 2 includes a hollow accommodating cavity that opens toward each other, for accommodating at least a portion of the communication module 1. In one embodiment, only the first upper shell 3 includes the first accommodating cavity that opens toward the base 2. In another embodiment, only the base 2 includes the first accommodating cavity that opens toward the first upper shell 3. In another embodiment, the first upper shell 3 may include a portion of the accommodating cavity that opens toward the base 2, and the base 2 may include another portion of the accommodating cavity that opens toward 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. It can be understood by those skilled in the art 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 using snaps or screws. A second accommodating cavity is formed between the second upper shell 4 and the base 2. The end of the second upper shell 4 facing away from the first upper shell 3 and one end of the base 2 form an outlet 5 for receiving or receiving a target wire.
[0066] Compared to existing receivers with an integral upper shell design, each time the target wire connected to or taken out of the receiver needs to be operated, such as wiring, fixing, removing wires, or changing wires, the entire upper shell needs to be opened, exposing the entire communication module 1. Improper operation can damage circuit components such as chips in the communication module 1, increasing unnecessary risks. In this embodiment, the receiver has a first upper shell 3 and a second upper shell 4 that are each detachably connected to the base 2. The first accommodating cavity formed between the first upper shell 3 and the base 2 is used to accommodate at least a portion of the communication module 1, and the target wire connected to or taken out of 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 the corresponding operation on the target wire in the second accommodating cavity, without removing the first upper shell 3, and without exposing the entire communication module 1. This improves operational efficiency and 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, thereby enabling the base 2, the first upper shell 3, and the second upper shell 4 to 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, the coupler 6 is preferably provided on the first upper shell 3 to facilitate the disassembly of the second upper shell 4. The following is an exemplary description using the case where the coupler 6 is provided 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 abutting portion 41 is provided on the side of the second upper shell 4 facing the base 2, and the coupler 6 includes a second abutting portion 61 that matches the first abutting portion 41. The first abutting portion 41 abuts against the second abutting 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 provided on the 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 and 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 dust-proof effect to achieve a sealed connection between the first upper shell 3 and the second upper shell 4.
[0070] like Figure 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 surfaces 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] Further, combined with Figure 8 and Figure 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 a second coupling connection portion is provided 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 first sliding grooves 62 provided on opposite sides of the coupler 6; the second coupling connection portion includes a first sliding member 63 that matches the first sliding groove 62; the first sliding member 63 is provided to cooperate with the first sliding groove 62 to form the relative coupling relationship in the vertical direction in which the second end B of the second upper shell 4 is slidably connected to the base 2. The first sliding groove 62 can be an independent sliding groove provided on the coupler 6, or it can be a guide rib 621 extending from the coupler 6, and the guide rib 621 cooperates with the main body of the first upper shell 3 to form a sliding groove. The first sliding member 63 can be obtained by extending the second upper shell 4 toward the base 2, so that the first sliding member 63 is suitable for cooperating with the first sliding groove 62 to slide in the vertical direction, thereby allowing the second upper shell 4 to be quickly installed and removed by sliding in the vertical direction. In addition, in some embodiments, the first sliding groove 62 and the first sliding member 63 can 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 that matches 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 via screws in corresponding screw holes 103 and 104, and the second end B is connected to the base 2 via the relative coupling relationship between the second coupling portion and the first coupling portion. In this embodiment, the second upper shell 4 can press the first upper shell 3 against the base 2 via the coupler 6 at the second end B near the first upper shell 3. The second upper shell 4 is connected to the base 2 via screws at a location away from the first end A of the first upper shell 3, that is, near the outlet 5, thereby coupling the base 2, the first upper shell 3, the coupler 6, and the second upper shell 4 into a single integrated structure. Because in this embodiment, the first upper shell 3 can be fixed to the base 2 solely via screws at the first end A of the second upper shell 4 near the outlet 5, no additional fasteners, 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 near the first upper shell 3. The screw at the first end A is located away from the first upper shell 3 and also away from electronic devices, such as the antenna, located in the first accommodating cavity. This avoids the problem of screws being installed in the middle of the receiver to secure the upper shell, which can interfere with the receiver's wireless signal reception, as is common in the prior art. This ensures the stability of the receiver's signal reception. Furthermore, the coupler 6 couples the first upper shell 3 and the second upper shell 4 into a single unit, eliminating the need for screws in the middle of the receiver to affect its overall appearance, resulting in a neat and aesthetically pleasing overall structure.
[0073] Further, 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 taken out; 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 second upper shell 4 fix the first upper shell 3 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] Furthermore, in some embodiments, the end of the coupler 6 facing the outlet 5 is provided with multiple connection ports 64 for connecting or disconnecting the target wires 14. An isolation structure 65 is provided between any two adjacent connection ports 64. This isolation structure 65 allows the target wires 14 in two adjacent connection ports 64 to meet different creepage distance requirements, thereby improving the safety of the receiver. Exemplarily, the isolation structure 65 ensures that the distance between the target wires 14 in two adjacent connection ports 64 is 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 designated direction from the third end to the fourth end of the second upper shell 4, the designated direction can be understood as the horizontal direction, and the plane perpendicular to the designated 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. Figure 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 terminals 711 on the wiring structure 71, preventing the wiring operation terminals 711 in the receiver from being exposed to the surface, and improving the safety of the receiver. When the second upper shell 4 is removed from the base 2, the wiring operation opening 66 is set to an exposed state to facilitate user operation when the user needs to operate the wiring operation terminals 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 removed to achieve protection and operation of the wiring operation terminal 711, so that the receiver is compatible with the requirements of built-in installation and external installation.
[0076] Furthermore, if Figure 9As shown, in some embodiments, the base 2 is provided with a support portion 21 on the side facing the first upper shell 3 for supporting 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 both the fourth accommodating cavity 22 and the fifth accommodating cavity 23. There may be one or more support portions 21, and their positions may be set in the middle or around the base 2, which is not limited here. In this embodiment, circuit components are provided on both the front and back sides of the circuit board 7, which not only reduces the volume of the receiver, but also allows the circuit components on the circuit board 7 that generate more heat to be arranged on the front and back sides of the circuit board 7 respectively for separate heat dissipation, which is beneficial to reducing the temperature of the receiver during operation.
[0077] Furthermore, 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 extends a limiting protrusion 31 corresponding to the spring antenna 72 on a 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 uses a spring antenna 72 and is provided with a limiting protrusion 31 to fix the position of the spring antenna 72, preventing it from tilting left or right. Compared to the uncontrollable position of a wire antenna, the position of the spring antenna 72 in this embodiment is controllable and can be installed within the shell, allowing the receiver to meet the requirements of external installation.
[0078] Furthermore, in some embodiments, the receiver further includes a trigger member 73, for example, the trigger member 73 can be set as a micro switch, and the number of the trigger members 73 can be set according to actual applications. The trigger member 73 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 output a trigger signal to the communication unit 11 in response to external manipulation. In this embodiment, the trigger member 73 is arranged at the end of the circuit board 7 opposite to the wiring structure 71, that is, the trigger member 73 is located on the circuit board 7 at the end away from the wiring structure 71. Since the target wire 14 connected to the wiring structure 71 may be mains electricity, that is, strong electricity, the trigger member 73 is set at a position away from strong electricity in this embodiment to avoid the user from directly or indirectly touching the trigger member 73 and contacting the strong electricity, thereby improving the safety of the receiver.
[0079] Furthermore, in some embodiments, the first upper shell 3 is provided with a button hole 32, the circuit board 7 is provided with a trigger member 73 positioned to match the button hole 32, and a guide slot 33 extending from the first upper shell 3 toward the trigger member 73 and connected to the button hole 32. The receiver further includes at least one button 8 matching the guide slot 33. Exemplarily, the button 8 is in the form of a guide post, extending through and confined within the guide slot 33. One end of the button 8 is exposed on the outer surface of the first upper shell 3, while the other end is located at a corresponding position near the trigger member 73, and can trigger the trigger member 73 in response to external force transmitted from one end of the button 8. A limiting buckle 331 extends from the guide slot 33 in a direction near the trigger member 73. The button 8 is provided with a limiting portion 81 matching the limiting buckle 331. The limiting portion 81 cooperates with the limiting 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 manipulation force on the outer surface of the first upper shell 3. The button 8 moves downward along the guide groove 33, triggering the corresponding trigger member 73, thereby outputting a trigger signal to the communication unit. At the same time, the button 8 returns to the outer surface of the first upper shell 3 in response to the reset force of the trigger member 73. The button 8 is limited by the cooperation between the limit portion 81 and the limit buckle 331, and the button 8 will not slide out of the outer surface of the first upper shell 3.
[0080] Furthermore, in some embodiments, a light-emitting element 74 is further provided on the circuit board 7. For example, the light-emitting element 74 may be an LED, and the number and position of the light-emitting elements 74 may be set according to actual applications. The light-emitting element 74 is electrically connected to the communication module 1, for example, the trigger element 73 is electrically connected to the communication unit 11, so as to emit light of a specified color in response to a signal sent by the communication unit 11. At least one light-transmitting through hole 34 is provided on the first upper shell 3, and a light-guiding channel 35 extending toward the light-emitting element 74 in the fifth accommodating cavity 23 of the first upper shell 3 is provided. 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 element 74, so as to guide the light to the light-transmitting through hole 34 via the light-guiding channel 35 when the light-emitting element 74 emits light. In which, reflective materials may be provided 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-bonding 36. The number and position of the anti-bonding 36 can be set according to actual needs. For example, four anti-bonding 36 can be set 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] Further, combined with Figures 14 to 17 As shown, in some embodiments, the second upper shell 4 forms a wiring channel 9 between the end A near the wire outlet 5 and the base 2 for the target wire 14 to pass through in a bent state. To ensure the reliability of the receiver and the safety of the receiver when installed externally, the target wire 14 connected to the receiver must meet a certain tensile force. For example, when the receiver is installed externally, the target wire 14 connected to the receiver must pass a tensile test requirement of 20N. Therefore, in this embodiment, a wiring channel 9 is formed between the second upper shell 4 at one end 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 combined with the screw at one 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 this 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 the pulling force 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] Furthermore, in some embodiments, at least one first wire pressing member is provided on one side of the second upper shell 4 facing the base 2, and at least one first wire pressing groove matching the first wire pressing member 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 wire pressing member and the first wire pressing groove. Wherein, the first wire pressing member can be a first wire pressing portion 42 obtained by extending the second upper shell 4 in the direction toward the base 2, and one end of the first wire pressing portion 42 used for pressing can be a plane or a serrated surface, and the first wire pressing groove includes at least two protrusions (431, 432) extending from the base 2 toward the second upper shell 4, and a first wire pressing groove is formed between any two adjacent protrusions (431, 432), and the vertical extension direction of the first wire pressing portion 42 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 cooperation between the first wire pressing member and the first wire pressing 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 pressing member and the first wire pressing groove can be set in reverse. For example, at least one first wire pressing groove is provided on the side of the second upper shell 4 facing the base 2, and at least one first wire pressing member matching the first wire pressing groove is provided 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 pressing member and the first wire pressing groove.
[0084] Specifically, if Figure 17As shown, the first wire-pressing member forms a first wire-pressing end 421 of the first wire-pressing member at the end near the first wire-pressing groove; the first wire-pressing groove forms a second wire-pressing end 422 of the first wire-pressing groove at the end near the side wall of the first wire-pressing member; wherein, the vertical distance between the first wire-pressing end 421 of the first wire-pressing member and the second wire-pressing end 422 of the first wire-pressing groove is less 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 to 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-pressing member and the first wire-pressing 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. The first wire-pressing member squeezes part of the target wire 14 into the first wire-pressing groove, and the target wire 14 forms a V-shaped bending deformation in the first wire-pressing 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 tension 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 tension that the target wire 14 in the receiver can withstand is enhanced, thereby improving the reliability and safety of the receiver.
[0085] Furthermore, a second wire pressing member is provided on the side of the first wire pressing member close to the communication module 1, and the extension direction of the second wire pressing member is consistent with that of the first wire pressing member; the second wire pressing member forms a third wire pressing end 441 of the second wire pressing member at the end close to the first wire pressing groove; the distance between the first wire pressing end 421 of the first wire pressing member and the second wire pressing end 422 of the first wire pressing groove is less than the distance between the third wire pressing end 441 of the second wire pressing member and the second wire pressing end 422 of the first wire pressing groove. In this embodiment, the second wire pressing member can be a second wire pressing portion 44 obtained by extending the second upper shell 4 in the direction toward the base 2, and the wire pressing end of the second wire pressing portion 44 can be a flat surface or a serrated surface. After the target wire 14 forms a V-shaped bending deformation in the first wire pressing 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 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 subject 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 provided between the first wire pressing member such as the first wire pressing portion 42 and the wiring structure 71. After the target wire 14 undergoes V-shaped bending deformation, it is also subjected to the wire pressing force of the second wire pressing portion 44, 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 it 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 position-limiting clamping portion 45 is provided on opposite sides of the second upper shell 4 facing the base 2, for limiting the position of the second upper shell 4 and clamping it to a corresponding position on 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 and 432, thereby forming a wiring channel 9 for the target wire 14 to pass through in a bent state.
[0087] Furthermore, the second upper shell 4 is connected to the base 2 by two screws 101 and 102 arranged opposite to each other; 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, and 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 sequence, and the second screw 102 passes through and is installed in the second mounting hole 104 and the fourth mounting hole 106 in sequence, 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 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 since the direction of the force exerted 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 exerted by the screw is consistent with the force exerted 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, comprising the receiver described above and an electrical appliance, wherein the receiver is electrically connected to the electrical appliance, and after the receiver detects an external signal, controls the operating 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 receiver described above and can be wirelessly controlled.
