For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0048] In view of the fact that doorbell receivers powered by strong electricity often fail to report a false alarm during operation, that is, the receiver often fails to respond when the doorbell trigger is triggered. The inventors of the present application have discovered through research that since the voltage of the indoor socket is much higher than the operating voltage of the internal circuit of the doorbell receiver, the doorbell receiver needs to step down the received power, that is, the strong electricity needs to be converted into weak electricity for the normal operation of the internal circuit. At the same time, since the step-down module and communication module inside the doorbell receiver are arranged on the same circuit board, the step-down module will generate electromagnetic interference to the communication module during operation, resulting in an increased probability of false alarms of the doorbell receiver during use.

[0049] In order to solve the above problems, the present application adopts a method of separating the power board and the communication board inside the doorbell receiver to reduce the interference of the power board on the communication board during the voltage reduction process, so as to ensure that the doorbell receiver can better receive the wireless signal emitted by the doorbell trigger, thereby reducing the probability of missed reports by the doorbell receiver.

[0050] According to one aspect of the embodiment of the present application, a doorbell is provided. Figure 1 , the figure shows the usage scenario of the doorbell 500. Figure 1 As shown, the doorbell 500 includes a doorbell trigger 100 and a doorbell receiver 200, wherein the doorbell trigger 100 is arranged outdoors and can generally be a wireless signal transmitter with a push switch or a touch switch. When a visitor visits, the doorbell trigger 100 is triggered by pressing or touching, so that the doorbell trigger 100 sends a wireless signal to the doorbell receiver 200. The doorbell receiver 200 is connected to the indoor socket 300. After receiving the wireless signal sent by the doorbell trigger 100, the doorbell receiver 200 makes a preset response to notify the homeowner. Specifically, the preset response can be a ringing, an indicator light, a voice broadcast, etc., which are not specifically limited.

[0051] According to another aspect of the embodiment of the present application, a doorbell receiver 200 applied to the doorbell 500 is provided. Figure 2 and Figure 3 , Figure 2 FIG. 2 shows a three-dimensional structure of a doorbell receiver 200. Figure 3 The exploded structure of the doorbell receiver 200 is shown in FIG. The doorbell receiver 200 includes: a housing 210, a power board 220, a communication board 230, and a response device 240. The power board 220, the communication board 230, and the response device 240 are all arranged inside the housing 210, and the power board 220 and the communication board 230 are separated. Figure 4As shown in , the power board 220 is provided with a power input terminal 2201, a voltage reducer 2202 and a rectifier 2203, and the communication board 230 is provided with a controller 2301 and a wireless signal receiver 2302. The power input terminal 2201 is connected to the input terminal of the voltage reducer 2202, the output terminal of the voltage reducer 2202 is connected to the input terminal of the rectifier 2203, the output terminal of the rectifier 2203 is connected to the controller 2301, and the controller 2301 is respectively connected to the wireless signal receiver 2302 and the response device 240. The controller 2301 controls the response device 240 to send a preset response in response to the wireless signal received by the wireless signal receiver 2302.

[0052] Specifically, the power input terminal 2201 is used to receive external input AC power and output it to the buck 2202. The buck 2202 is used to step down the input AC power and output it to the rectifier 2203. The rectifier 2203 is used to convert the input AC power into DC power and output it to the controller 2301. While supplying power to the controller 2301, the controller 2301 also supplies power to the wireless signal receiver 2302 and the response device 240.

[0053] The power board 220 is used for power management, and is mainly responsible for power conversion, voltage stabilization, overload and overvoltage protection, etc. Specifically, power conversion refers to converting the external input strong electricity (high voltage AC, such as mains electricity) into weak electricity (low voltage DC) required by the communication board 230 and the response device 240 and other internal circuit structures. Voltage stabilization refers to maintaining the stability of the output voltage to prevent voltage fluctuations from damaging the internal circuit structure. Overload and overvoltage protection means that when the output current or voltage exceeds the set value, the power supply will be automatically cut off to protect the internal circuit structure from damage.

[0054] like Figure 3 As shown in FIG. 2 , a power conversion module 221 is provided on the power board 220, and the power conversion module 221 converts the external input strong electricity into weak electricity and supplies power to the communication board 230 and the response device 240. Specifically, as Figure 5 As shown in , the power conversion module 221 includes a buck 2202 and a rectifier 2203 .

[0055] The wireless signal receiver 2302 can use wireless communication methods such as WiFi, Radio Frequency (RF), ZigBee, etc. to communicate wirelessly with the doorbell trigger 100.

[0056] The response device 240 can be a speaker that responds by ringing or voice broadcasting, or an indicator light that responds by emitting light. Of course, it can also provide sound and light feedback at the same time, which is not limited here.

[0057] When the buck 2202 and the rectifier 2203 cooperate to perform power conversion, certain electromagnetic interference will be generated, thereby affecting the transmission effect of the wireless signal between the wireless signal receiver 2302 and the doorbell trigger 100, which is also the main reason why the existing doorbell receiver often misses reports. In this regard, in the doorbell receiver 200 provided in the embodiment of the present application, the power board 220 and the communication board 230 are each independently designed as a circuit board, and the power board 220 and the communication board 230 are separated and arranged in a structure to minimize the electromagnetic interference of the buck 2202 and the rectifier 2203 on the power board 220 to the wireless signal receiver 2302 on the communication board 230 during the process of converting strong electricity into weak electricity, thereby ensuring the effect of wireless signal transmission between the wireless signal receiver 2302 and the doorbell trigger 100, reducing the probability of missed reports of the doorbell receiver 200, and improving user experience.

[0058] In order to further reduce the interference of the power board 220 to the communication board 230, the present application also proposes an implementation method. Figure 3 , and further combined with Figure 6 and Figure 7 , Figure 6 and Figure 7 The exploded structure of the doorbell receiver under two viewing angles is shown in FIG. A partition 211 is disposed inside the housing 210 , and the partition 211 divides the internal space of the housing 210 into a first installation cavity 212 and a second installation cavity 213 . The power board 220 is disposed in the first installation cavity 212 , and the communication board 230 is disposed in the second installation cavity 213 .

[0059] Specifically, the partition 211 can be integrally injection molded with the housing 210, or can be separately molded and then fixedly installed in the housing 210 by means of clamping, threading, etc. The partition 211 divides the internal space of the housing 210 into a first installation cavity 212 and a second installation cavity 213, and the power board 220 and the communication board 230 are respectively placed in the first installation cavity 212 and the second installation cavity 213, so that the power board 220 and the communication board 230 are further isolated, so as to better reduce the electromagnetic interference of the power board 220 to the communication board 230.

[0060] Currently, most doorbell receivers on the market use a low-frequency wireless communication method such as 433MHz. After research, the inventors of the present application found that when using 433MHz, the communication module is very susceptible to interference from the power conversion module on the power board, resulting in a significant decrease in communication distance and stability, causing the doorbell receiver to often miss reports.

[0061] In view of the above problems, in some embodiments of the present application, the communication frequency band of the wireless signal receiver 2302 is configured to be 915 MHz or 868 MHz. Specifically, the wireless signal receiver 2302 can be configured in software and hardware to perform wireless communication with the doorbell trigger 100 at 915 MHz or 868 MHz. The specific configuration method can be performed in an existing manner, which will not be described in detail here.

[0062] After practical verification, it has been found that the use of 915MHz or 868MHz high-frequency wireless communication can effectively improve the anti-interference ability and weaken the interference effect of the power board 220 on the communication between the wireless signal receiver 2302 and the doorbell trigger 100, compared with the 433MHz low-frequency communication.

[0063] In order to achieve that the part of the doorbell receiver 200 connected to the socket 300 can be replaced separately when it is damaged to extend the service life of the doorbell receiver 200, the present application further proposes an implementation method, which is described in detail in detail in detail. Figure 6 and Figure 7 The housing 210 is provided with an installation opening 214 at a position opposite to the first installation cavity 212. A cover plate 215 is detachably connected to the installation opening 214. A power pin 216 is provided through the cover plate 215. The part of the power pin 216 located inside the cover plate 215 is connected to the power input terminal 2201. The power pin 216 is used to connect to the socket 300 (such as Figure 1 ) is connected to input the power of the socket 300 to the power input terminal 2201.

[0064] exist Figure 6 and Figure 7 In the specific embodiment shown, the edge of the cover plate 215 is provided with a buckle 2151, and the inner edge of the installation opening 214 is provided with a notch 2141 and a locking protrusion 2142. When installing the cover plate 215, the buckle 2151 is aligned with the notch 2141, and then the buckle 2151 is extended from the notch 2141 to make the inner wall of the cover plate 215 abut against the locking protrusion 2142, and then the cover plate 215 is rotated to make the buckle 2151 and the locking protrusion 2142 engage, forming a Figure 8 In the state shown, the cover plate 215 is assembled and fixed to the housing 210 at the installation opening 214. It is understandable that in some other embodiments, the cover plate 215 can also be assembled and fixed to the housing 210 by inserting and clamping or by connecting with threaded fasteners.

[0065] An installation opening 214 is opened on the shell 210 at a position opposite to the first installation cavity 212, and a cover plate 215 with a power pin 216 extending therethrough is connected to the installation opening 214 in a detachable manner. This not only facilitates replacement of the power pin 216 when it is damaged, but also ensures that the assembled power pin 216 is close to the power board 220, thereby facilitating electrical connection between the two.

[0066] For manufacturers, since different countries have different specifications for power pins, in order to reduce production costs, they can use the same body with different power pins to meet the specifications of different countries. However, this method can cause users to directly remove the power pins and touch the power board, which can easily cause electric shock and aging, creating safety hazards.

[0067] In order to solve the above problem, during the assembly process, when the cover 215 and the shell 210 are assembled, glue can be applied between the cover 215 and the inner edge of the mounting port 214 to fix them, so that the user cannot remove the cover 215 by themselves, thereby ensuring safety. During the production process, the same main body can still be used with different power pins for assembly, thereby achieving control of production costs.

[0068] Regarding the specific structure of the response device 240, this application proposes an implementation method. Figure 3 , and further combined with Fig. 9 , Fig. 9 2 shows a three-dimensional structure of the doorbell receiver 200 from one perspective. The response device 240 includes an indicator light 241 disposed on the side of the power board 220 away from the power pin 216, and a circular light-transmitting area 217 is disposed on the housing 210 at a position opposite to the indicator light 241. The controller 2301 is connected to the indicator light 241.

[0069] Specifically, after receiving the wireless signal sent by the doorbell trigger 100, the wireless signal receiver 2302 sends a corresponding trigger signal to the controller 2301, so that the controller 2301 controls the indicator light 241 to emit light, and the light emitted by the indicator light 241 is emitted from the annular light-transmitting area 217.

[0070] The indicator light 241 is arranged on the side of the power board 220 away from the power pin 216, so that after the power pin 216 is inserted into the socket 300, the indicator light 241 faces the indoor space, and further emits light through the annular light-transmitting area 217, so that compared with ordinary point lights, it can remind the user more obviously, so that the user can better perceive whether there are visitors.

[0071] Considering that if the annular light-transmitting area 217 and the shell 210 adopt an integral structure, different materials need to be used for injection molding in the production and manufacturing of the entire shell 210, which increases the difficulty of production and increases the cost. Therefore, in some embodiments of the present application, the annular light-transmitting area 217 and the shell 210 are designed to be separated to reduce the difficulty and cost of production. For details, please refer to Figure 6 and Figure 7 A light guide 251 and a light shield 252 are disposed in the first installation cavity 212. The light guide 251 is disposed opposite to the indicator light 241. The end of the light guide 251 away from the indicator light 241 has an annular structure 2511. The light shield 252 covers the inner edge of the annular structure 2511. A window 218 is provided on the housing 210 at a position opposite to the light guide 251. The annular structure 2511 is disposed at the inner edge of the window 218 to form an annular light-transmitting area 217.

[0072] Specifically, the light guide 251 is made of transparent material as a whole. The light emitted by the indicator light 241 enters the light guide 251 and is refracted out. The light refracted from the annular structure 2511 directly reaches the outside of the shell 210, while the light refracted from the middle part of the annular structure 2511 on the light guide 251 is blocked by the light blocking plate 252 and reflected back into the inside of the shell 210, finally forming an annular luminous area outside the shell 210 to respond to the user.

[0073] like Figure 6 and Figure 7 As shown in the figure, a card interface 2512 and a positioning hole 2513 can be provided on the side of the light guide 251 facing the light baffle 252 and located on the inner periphery of the annular structure 2511. A card connecting piece 2521 and a positioning column 2522 are provided on the light baffle 252 facing each other. By inserting the positioning column 2522 into the positioning hole 2513 and connecting the card connecting piece 2521 to the card interface 2512, the light baffle 252 and the light guide 251 are assembled and fixed.

[0074] Please continue reading Figure 7 A card plate 2514 and a connecting plate 2515 are respectively provided on the opposite sides of the light guide 251, and a card slot 2181 and a connecting column 2182 are correspondingly provided on the inner wall of the edge of the window 218. After the light baffle 252 and the light guide 251 are assembled and fixed, the card plate 2514 is first inserted into the card slot 2181, and then the connecting plate 2515 is fixedly connected to the connecting column 2182 by threaded fasteners to realize the assembly of the light guide 251 and the light baffle 252 on the shell 210.

[0075] In this embodiment, firstly, the light guide 251, the light shielding plate 252 and the housing 210 are separated into three parts, so that each of them can be injection molded with the same material, which is convenient for production and manufacturing. Secondly, by setting the annular structure 2511 on the light guide 251 through the inner edge of the window 218, the light emitted by the indicator light 241 can be emitted through the annular structure 2511 to form an annular lighting area. Finally, the light shielding plate 252 covers the part of the light guide 251 located on the inner periphery of the annular structure 2511, so that the outer surface of the housing 210 is smooth and neat, and the boundary of the outer circle in the annular lighting area is clear and bright.

[0076] Regarding the specific structure of the response device 240, this application also proposes an implementation method. Figure 6 and Figure 7 The response device 240 includes a speaker 242. A plurality of sound holes 219 are evenly provided at positions on the housing 210 opposite to the second mounting cavity 213. The apertures of the plurality of sound holes 219 gradually decrease from the center to the edge. The speaker 242 is disposed inside the sound holes 219. The controller 2301 is connected to the speaker 242.

[0077] Specifically, after receiving the wireless signal sent by the doorbell trigger 100, the wireless signal receiver 2302 sends a corresponding trigger signal to the controller 2301, so that the controller 2301 controls the speaker 242 to make a sound.

[0078] Specifically, the speaker 242 can be configured to respond in the form of a ring or a voice announcement. By setting the apertures of the multiple sound outlets 219 to gradually decrease from the center to the edge, most of the sound waves generated by the speaker 242 can be emitted from the center position, the sound wave energy is more concentrated, and the sound quality is clear.

[0079] Regarding the installation of the speaker 242, this application proposes an implementation method. Please refer to Figure 6 and Figure 7 As shown in the figure, the inner wall of the housing 210 at the edge of the sound outlet 219 encloses a limiting protrusion 2421, and the speaker 242 is at least partially accommodated in the limiting protrusion 2421. The inner wall of the housing 210 on the side away from the sound outlet 219 is provided with a pressing column 2422, and the pressing column 2422 presses against the side of the speaker 242 away from the sound outlet 219 through an elastic buffer 2423.

[0080] In this embodiment, the speaker 242 can be stably fixed in the housing 210 by the cooperation between the limiting protrusion 2421 and the pressing column 2422. At the same time, if the pressing column 2422 exerts too much pressure on the speaker 242, it may not only affect the sound output effect of the speaker 242, but also easily cause damage to the speaker 242. Therefore, an elastic buffer 2423 is clamped between the pressing column 2422 and the speaker 242, and the elastic buffer 2423 buffers the pressure of the pressing column 2422 to ensure the structural stability of the speaker 242 and the sound quality of the output sound. Specifically, the elastic buffer 2423 can be made of soft silicone, sponge, etc., which is not limited here.

[0081] In order to expand the function of the doorbell receiver 200, this application also proposes an implementation method, please refer to Fig.10 The figure shows the internal structure of the doorbell receiver. A plurality of switch contacts 231 are arranged on the communication board 230, and a plurality of buttons 260 are embedded in the housing 210 at positions opposite to the switch contacts 231. The plurality of buttons 260 are interconnected inside the housing 210 to form an integrated structure.

[0082] In order to reduce the number of parts and improve assembly efficiency, such as Fig.10 As shown in , adjacent keys 260 are connected to each other through connecting sections 261 to form an integrated structure. Specifically, multiple keys and the connecting sections 261 therebetween are integrally formed in one mold. On this basis, a fixing hole 2611 can be further provided on the connecting section 261, and a fixing column 2612 is correspondingly provided on the inner wall of the housing 210. By sleeve-fitting the fixing hole 2611 on the fixing column 2612, all keys 260 can be embedded and fixed to the housing 210.

[0083] Specifically, the button 260 may include a setting button, a ringtone selection button, a volume adjustment button, etc., which are not limited here.

[0084] Finally, some details of the doorbell receiver 200 are described in detail according to the preferred embodiment provided in this application. Figure 6 A first fixing column 271 is disposed in the first installation cavity 212, and a first threaded fastener 281 passes through the power board 220 and is connected to the first fixing column 271 to fix the power board 220 in the first installation cavity 212. Similarly, a second fixing column 272 is disposed in the second installation cavity 213, and a second threaded fastener 282 passes through the communication board 230 and is connected to the second fixing column 272 to fix the communication board 230 in the second installation cavity 213.

[0085] In addition, if Figure 6 and Figure 7As shown in , the housing 210 may include a first housing 2101 and a second housing 2102, the first housing 2101 and the second housing 2102 are buckled and connected to each other, a third fixing column 273 is provided at a position of the inner wall of the first housing 2101 opposite to the communication board 230, a fourth fixing column 274 is correspondingly provided on the inner wall of the second housing 2102, and a position avoidance hole 232 is provided on the communication board 230 for the fourth fixing column 274 to pass through. After the first housing 2101 and the second housing 2102 are buckled, the third fixing column 273 and the fourth fixing column 274 are butted against each other, and the third threaded fastener 283 is inserted from the outer wall of the first housing 2101 into the third fixing column 273 and connected to the fourth fixing column 274, so that the first housing 2101 and the second housing 2102 are assembled and fixed to each other.
