These heat sinks are typically made of metal, with two single-piece fins symmetrically positioned on either side of the doorbell. These metal heat sinks absorb some of the electromagnetic energy in the air, reducing the energy conversion efficiency of the entire communication system and, in turn, impacting the antenna's communication performance.

[0047] Reference Figures 1 to 7 The present invention provides an electronic doorbell, comprising:

[0048] carrier;

[0049] A first antenna 331 is fixed to the carrier;

[0050] The second antenna 332 is spaced apart from the first antenna 331 and is disposed on the carrier. The communication distance of the second antenna 332 is shorter than that of the first antenna 331 .

[0051] Existing electronic doorbells typically use a Bluetooth antenna or WiFi antenna to communicate with mobile terminals or access the Internet of Things. However, Bluetooth antennas or WiFi antennas have limited transmission range. This embodiment adopts a dual-antenna design, where the first antenna 331 is used for long-distance communication and the second antenna 332 is used for short-distance communication. However, antennas work by receiving electromagnetic waves, and electromagnetic waves of various frequencies exist in space. If the two antennas are too close, when receiving electromagnetic waves, they may receive unrelated electromagnetic waves of the same frequency, thereby interfering with normal communication. Therefore, in this embodiment, the first antenna 331 and the second antenna 332 are spaced apart to achieve spatial isolation and reduce mutual interference between the two antennas.

[0052] The first antenna 331 can be a LoRa antenna, and the second antenna 332 can be any of a Bluetooth antenna, a WiFi antenna, and a Zigbee antenna. LoRa antennas enable long-range communication up to 10 miles in line-of-sight conditions, have deep penetration capabilities through concrete and foliage, and require ultra-low power. LoRa boasts extremely high energy efficiency and interference immunity. Its low receive bandwidth and unique coding scheme enable LoRa radios to achieve receiver sensitivity as low as -140dBm. These characteristics make LoRa antennas ideal for long-range communication between low-power devices. However, with the continued development of LoRa and the increasing number of LoRa devices and network deployments, spectrum interference may occur. LoRa deployment requires users to establish their own network. Bluetooth antennas, on the other hand, are suitable for short-range data transmission, offering low power consumption and suitable for battery-powered devices. They also support the transmission of text, images, audio, and video, with fast transmission rates and low latency. WiFi antennas are also suitable for short-range data transmission, allowing access to the network from anywhere within the wireless signal coverage area. Users connected to a wireless local area network can move and remain connected to the network. In this embodiment, a wireless communication module is constructed using both a LoRa antenna and a Bluetooth / WiFi antenna. The Bluetooth / WiFi antenna solves the problem of short-range connectivity with low power consumption, while the LoRa antenna solves the problem of long-range connectivity with low power consumption, enabling the electronic doorbell to achieve longer-range communication with lower power consumption.

[0053] Alternatively, the first antenna 331 and the second antenna 332 are both Bluetooth / WiFi antennas, that is, the electronic doorbell can adopt a dual WiFi antenna design, or a dual Bluetooth antenna design, or a WiFi antenna and a Bluetooth antenna design. When one antenna fails to communicate, the other antenna can still be used for communication, thereby improving the reliability of the electronic doorbell.

[0054] The electronic doorbell also includes a front housing 310, which forms a cavity for accommodating a first antenna 331 and a second antenna 332. Due to the limited internal space of the cavity, in addition to the first and second antennas 331 and 332, components such as a camera, a speaker, a display screen, and an electronic control board 320 must also be accommodated. Within this limited space, the placement of the first and second antennas 331 and 332 must also be considered to achieve good isolation and prevent interference between the two antennas. In this embodiment, the first and second antennas 331 and 332 are spaced apart. For example, the first and second antennas 331 and 332 are symmetrically placed on the same side of the front housing 310; or symmetrically placed on opposite sides of the front housing 310; or placed at opposite corners of the front housing 310, thereby maintaining a certain distance between the first and second antennas 331 and 332, achieving spatial isolation. The spacing between the first and second antennas 331 and 332 is no less than 20 mm.

[0055] The present invention utilizes a dual-antenna design to stabilize wireless communication between an electronic doorbell and a mobile terminal. By spacing the first and second antennas, the two antennas are isolated, preventing mutual interference between the two antennas and thereby improving the radiation performance of the first and second antennas.

[0056] In one embodiment, the minimum distance s between the first antenna 331 and the second antenna 332 is not less than 20 mm.

[0057] Generally speaking, the greater the minimum distance s between the first antenna 331 and the second antenna 332, the better the isolation. However, electronic doorbells are limited in size. If the minimum distance s between the first antenna 331 and the second antenna 332 is too small, they will interfere with each other and affect communication with the mobile terminal. Placing the first antenna 331 and the second antenna 332 in a limited space and setting the minimum distance s between them to no less than 20 mm can meet the minimum isolation requirement.

[0058] In one embodiment, the first antenna 331 is a LoRa antenna, and the second antenna 332 is a Bluetooth or Wi-Fi antenna.

[0059] In this embodiment, the electronic doorbell's wireless communication module is constructed using a dual antenna system: a LoRa antenna and a Bluetooth / WiFi antenna. The Bluetooth / WiFi antenna addresses short-range connectivity with low power consumption, while the LoRa antenna addresses long-range connectivity with low power consumption. This allows the electronic doorbell to achieve longer-range communication with lower power consumption.

[0060] The electronic doorbell further includes a front shell 310 and an electric control board 320, and the carrier is the front shell 310 or the electric control board 320;

[0061] The first antenna 331 and the second antenna 332 are both disposed on the front housing 310;

[0062] Alternatively, the first antenna 331 and the second antenna 332 are both provided on the electric control board 320;

[0063] Alternatively, the first antenna 331 and the second antenna 332 are respectively provided on the front housing 310 and the electronic control board 320 .

[0064] In this embodiment, the electronic control board 320 is provided with a first feeding point and a second feeding point. The first antenna 331 and the second antenna 332 are fixed to the front housing 310 by heat-seal. The electronic control board is positioned above the first antenna 331 and the second antenna 332, so that the first feeding point and the second feeding point of the electronic control board 320 respectively contact the first antenna 331 and the second antenna 332. This provides a more stable structure for the first antenna 331 and the second antenna 332, and more reliable contact between the electronic control board 320 and the first antenna 331 and the second antenna 332, preventing frequency deviation and improving signal transmission stability.

[0065] Alternatively, the first antenna 331 and the second antenna 332 are both welded to the electronic control board 320, so that the first antenna 331 and the second antenna 332 are respectively fixed to the first feeding point and the second feeding point of the electronic control board 320 and are not easily displaced. At the same time, the first antenna and the second antenna can be kept away from electronic devices (such as doorbell buttons, display screens, cameras, etc.) on the front housing 100, reducing interference from electronic devices on the antennas.

[0066] Alternatively, the first antenna 331 and the second antenna 332 are separately located on the front housing 310 and the electronic control board 320. For example, the first antenna 331 is located on the front housing 310, and the second antenna 332 is located on the electronic control board 320; alternatively, the first antenna 331 is located on the electronic control board 320, and the second antenna 332 is located on the front housing 310. This reduces the area of ​​the front housing occupied by the two antennas compared to when both antennas are located on the front housing. Furthermore, the first antenna 331 and the second antenna 332 can be positioned away from the electronic components within the electronic doorbell, allowing for more favorable signal transmission. For example, the first antenna 331 is located on the electronic control board, while the second antenna 332 is located near the edge of the front housing, away from the electronic components. The absence of obstructions at the edge of the front housing further facilitates antenna signal transmission.

[0067] In one embodiment, the electronic doorbell further includes a cover plate 350;

[0068] The cover plate 350 and the front housing 310 form a cavity, and the first antenna 331 , the second antenna 332 , and the electronic control board 320 are disposed in the sealed cavity.

[0069] In this embodiment, the cover plate 350 can be made of metal. The cover plate is assembled with the front housing by screws and then mounted on the door panel. The entire structure has a high fireproof rating, high reliability, and is conducive to heat dissipation. Alternatively, the cover plate can be made of plastic.

[0070] The cover 350 and the front housing 310 form a sealed cavity, housing the first antenna 331, the second antenna 332, and the electronic control board 320. This prevents dust particles and external collisions from damaging the electronic components within the sealed cavity, thereby protecting the first antenna 331, the second antenna 332, and the electronic control board 320. This also mitigates the effects of temperature, humidity, weather, and other factors on the first antenna 331, the second antenna 332, and the electronic control board 320.

[0071] In one embodiment, the electronic doorbell further includes a doorbell button;

[0072] The doorbell button is disposed on the front housing, and the first antenna 331 and the second antenna 332 are disposed on both sides of the doorbell button.

[0073] In this embodiment, the first antenna 331 and the second antenna 332 are respectively arranged on both sides of the doorbell button to achieve a spatial separation between the first antenna and the second antenna to avoid mutual interference between the two antennas.

[0074] Electronic doorbells are mounted on door panels. To improve their anti-theft and fire resistance, existing door panels are often made of metal. Furthermore, the cover 350 is also made of metal. It's understandable that metal can couple antenna signals. After the antenna radiates electromagnetic waves or before receiving them, metal absorbs some of the electromagnetic energy in the air, reducing the energy conversion efficiency of the entire communication system and, in turn, impacting communication performance. The LoRa antenna and the Bluetooth / Wi-Fi antenna operate in the same frequency band. If the cover 350 provides the same degree of coupling to the LoRa and Bluetooth / Wi-Fi antennas—that is, if the cover 350 absorbs the electromagnetic waves transmitted or received by both antennas to the same degree—interference between the LoRa and Bluetooth / Wi-Fi antennas is minimal. However, if the cover 350 provides different degrees of coupling to the LoRa and Bluetooth / Wi-Fi antennas, interference between the LoRa and Bluetooth / Wi-Fi antennas is significant.

[0075] In this embodiment, when the cover plate 350 is a regular shape such as a rectangle, diamond, or circle, the first antenna 331 and the second antenna 332 are positioned on either side of the central axis of the cover plate 350, such that the minimum distances between the first antenna 331 and the second antenna 332 and the center point of the cover plate 350 are equal. The distances between the first antenna 331 and the second antenna 332 and various points on the cover plate 350 and the metal door panel surrounding the electronic doorbell are axially or centrally symmetrical. This ensures that the total energy of electromagnetic waves transmitted and received by the first antenna 331 and the second antenna 332 is absorbed by the cover plate 350 and the metal door panel surrounding the electronic doorbell to the same extent. In other words, the cover plate 350 and the metal door panel surrounding the electronic doorbell have the same degree of coupling with the first antenna 331 and the second antenna 332, thereby reducing coupling differences between the first antenna 331 and the second antenna 332, thereby reducing interference between the first antenna 331 and the second antenna 332 and improving signal transmission efficiency.

[0076] In one embodiment, the first antenna 331 is a LoRa antenna, and the second antenna 332 is a Bluetooth or Wi-Fi antenna.

[0077] In this embodiment, the electronic doorbell's wireless communication module is constructed using a dual antenna system: a LoRa antenna and a Bluetooth / WiFi antenna. The Bluetooth / WiFi antenna addresses short-range connectivity with low power consumption, while the LoRa antenna addresses long-range connectivity with low power consumption. This allows the electronic doorbell to achieve longer-range communication with lower power consumption.

[0078] In one embodiment, the electronic doorbell further includes a third antenna;

[0079] The third antenna is fixed on the front housing 310 or the electronic control board 320 , and the minimum distance between the third antenna and the first antenna 331 and the second antenna 332 is no less than 20 mm.

[0080] In this embodiment, there may be multiple third antennas. The third antenna may be located in a corner of the front housing 310 to ensure a maximum distance from the first antenna 331 and the second antenna 332. To prevent interference between the antennas, in this embodiment, the distance between the third antenna and the first antenna 331 and the second antenna 332 is set to be no less than 20 mm to achieve good isolation.

[0081] In one embodiment, the third antenna is one of a Bluetooth antenna, a Wi-Fi antenna and a LoRa antenna.

[0082] In this embodiment, the electric control board 320 is further provided with a third feeding point, and the third antenna can be provided on the front housing 310 and abut against the electric control board 320 provided on the cover 350. Alternatively, the third antenna can be welded and fixed to the third feeding point on the electric control board 320.

[0083] This embodiment adopts a dual WiFi antenna design, or a dual Bluetooth antenna design, or a WiFi antenna and a Bluetooth antenna design. When one of the antenna signals is poor, the other antenna can also be used for short-range communication, thereby improving the reliability of the electronic doorbell.

[0084] In one embodiment, the electric control board 320 is disposed on the cover 350 and abuts against the first antenna 331 , the second antenna 332 , and the third antenna;

[0085] Alternatively, the electric control board 320 is disposed on the front housing 310 , and the first antenna 331 , the second antenna 332 , and the third antenna are installed on the electric control board 320 .

[0086] In this embodiment, the electronic control board 320 is mounted on the cover 350, and the first, second, and third antennas are fixed to the front housing 310 by heat-seal. This ensures the antennas are securely positioned and prevents displacement that could affect their consistency. When the cover 350 and front housing 310 are enclosed, the electronic control board 320 abuts the first, second, and third antennas, ensuring more reliable contact between the feed points on the electronic control board 320 and the first, second, and third antennas, respectively. This prevents poor contact between the antennas and the feed points, which could affect communication.

[0087] Alternatively, the electronic control board 320 is set on the front shell 310, and the first antenna 331, the second antenna 332 and the third antenna are respectively welded to the feeding points on the electronic control board 320, so that the contact area between the first antenna 331 and the second antenna 332 and the electronic control board 320 is fixed and not easily displaced.

[0088] In one embodiment, the electronic doorbell further includes a heat dissipation component, which is disposed close to the electronic control board 320 and in contact with the front housing 310 .

[0089] It is understood that the antenna, circuits on the electronic control board 320, and other electronic components within the electronic doorbell generate heat during operation, raising the temperature within the cavity. For temperature-sensitive electronic components, such as transistors and capacitors, elevated temperatures can lead to unstable performance and even shorten their service life. This embodiment utilizes a heat sink assembly to transfer heat from the cavity to the front housing, which then conducts it through the front housing to the outside air, achieving effective heat dissipation.

[0090] The present invention provides another electronic doorbell, comprising:

[0091] front shell 310;

[0092] The electric control panel 320 is provided with a feeding point;

[0093] An antenna assembly is provided on the front housing and connected to the feeding point of the electric control board;

[0094] The heat dissipation component is arranged on the front shell near the electric control board. The heat dissipation component is provided with a gap, and the gap is used for the antenna component to transmit signals.

[0095] In this embodiment, the electronic control board 320 is equipped with multiple functional circuits, such as a radio frequency generation circuit, a power supply circuit, and a main control circuit. The input of the radio frequency generation circuit is connected to the main control circuit, and the output of the radio frequency generation circuit is connected to the antenna assembly via a feed point to feed power to the antenna assembly, enabling the antenna assembly to transmit and receive electromagnetic waves. The electronic control board 320 can be fixed to the front housing 310, and the antenna assembly mounted on the electronic control board 320; alternatively, the antenna assembly can be fixed to the front housing 310 by heat fusion, and the electronic control board 320 is positioned above the antenna assembly and abuts the antenna assembly. Furthermore, the electronic control board 320 can use an aluminum substrate. An aluminum substrate is a metal-based copper-clad laminate with excellent heat dissipation. Generally, a single-sided board consists of a three-layer structure: an insulating layer, a circuit layer, and a metal base layer. The functional circuits are electrically connected through the circuit layer on the aluminum substrate. At the same time, the heat generated by the functional circuits can be conducted out of the housing cavity through the aluminum substrate to achieve heat dissipation.

[0096] The heat dissipation assembly includes a heat sink, which may be provided with slots, the number and location of which correspond to the antenna assembly. Alternatively, there may be multiple heat sinks, each of which is positioned around the periphery of the housing cavity and spaced along the inner wall of the front housing 310, with the slots between adjacent heat sinks corresponding to the antenna assembly. Heat sinks are typically made of metal and can interfere with signal transmission from the antenna assembly. Providing slots in the heat dissipation assembly allows the antenna assembly to transmit or receive signals through the slots, minimizing interference from the metal heat sink on the antenna assembly.

[0097] The electronic doorbell also includes electronic components such as a camera, buttons, display, and speaker, housed within the front housing 310. These components, along with the functional circuits on the electronic control board 320, generate heat during operation, raising the temperature in the central area of ​​the housing cavity. The electronic control board 320 contains numerous functional circuits and generates significant heat during operation, rapidly increasing its temperature. A heat sink assembly, located near the electronic control board 320, conducts heat from the board 320 to the surrounding area and then to the exterior of the housing cavity through the walls of the front housing 310, thereby lowering the temperature within the cavity and achieving effective heat dissipation.

[0098] This embodiment provides a slot on the heat sink assembly corresponding to the antenna assembly, allowing the antenna assembly's received / transmitted signals to be transmitted through the slot. This reduces interference from the heat sink assembly with the antenna assembly and improves the antenna assembly's radiation performance in the electronic doorbell. This helps mitigate interference from a single-piece heat sink assembly with the antenna. The slot reduces the heat sink assembly's footprint and costs without compromising heat dissipation performance.

[0099] In one embodiment, the electronic doorbell further comprises:

[0100] a cover plate 350 , wherein the cover plate 350 and the front housing 310 enclose a first cavity, and the electronic control board 320 , the antenna assembly, and the heat dissipation assembly are accommodated in the first cavity;

[0101] The electric control board 320 is disposed on the cover plate and abuts against the antenna assembly;

[0102] Alternatively, the electric control board 320 is disposed on the front housing, and the antenna assembly is installed on the electric control board 320 .

[0103] In this embodiment, the cover plate 350 and the front shell 310 are enclosed to form a first cavity. By accommodating the electronic control board 320, the antenna assembly and the heat dissipation assembly in the first cavity, it can play a dust-proof and / or waterproof role, reducing the impact of the external environment on the electronic control board 320, the antenna assembly and the heat dissipation assembly.

[0104] In one embodiment, the front housing 310 has a mounting portion, and the antenna assembly is mounted on the mounting portion.

[0105] The mounting portion and the cover plate 350 enclose a second cavity within the first cavity, and the antenna assembly is disposed in the second cavity.

[0106] In this embodiment, the mounting portion and the cover plate 350 enclose a second cavity within the first cavity, forming a second cavity within which the electronic control board 320 and antenna assembly are located. In addition, electronic components such as the doorbell button, camera, and display are also located within the second cavity. In this embodiment, the dual cavity formed by the mounting portion, the front shell 310, and the cover plate protects the electronic control board 320, antenna assembly, and other electronic components such as the doorbell button, camera, and display, effectively preventing dust particles and debris from entering and causing electrical interference. A heat dissipation assembly is located outside the second cavity and is connected to the mounting portion and the front shell, respectively, to conduct heat from the second cavity to the first cavity and then to the outside of the first cavity through the larger surface area of ​​the front shell 310. The heat dissipation assembly is located outside the first cavity and can also be spatially isolated from the antenna assembly by the mounting portion, thereby minimizing its impact on the antenna assembly. In addition, the area outside the second cavity and inside the first cavity can also be used to set up components such as mounting columns and limiting columns to fix them to the cover plate, avoiding the need to reserve additional positions for setting up components such as mounting columns and limiting columns in the mounting part, thereby limiting the layout positions of the electronic control board 320, antenna components and electronic devices.

[0107] This embodiment achieves a double seal by enclosing the cover plate 350 and the front housing 310 to form a primary seal, and the cover plate 350 and the mounting portion to form a secondary seal, providing a good sealing effect. Furthermore, to ensure the aesthetic appearance of the electronic doorbell, the seal between the cover plate 350 and the mounting portion can be strengthened, while a simple seal between the cover plate 350 and the front housing 310 can be sufficient.

[0108] In one embodiment, the electronic doorbell further comprises:

[0109] The sealing ring 360 is fixed on the front shell and is arranged around the mounting portion.

[0110] Sealing ring 360 effectively blocks liquids such as water and moisture, as well as debris such as dust particles, from entering the second cavity, thereby protecting the antenna assembly and electronic control board 320 from liquid damage and providing waterproof, moisture-proof, and / or dust-proof functionality. A heat dissipation assembly is disposed outside the second cavity, connected to sealing ring 360 and front housing 310, respectively, to conduct heat within the second cavity to the second cavity and then, through the larger surface area of ​​front housing 310, to the exterior of the first cavity.

[0111] In this embodiment, a sealing ring 360 is provided to surround the mounting portion, thereby providing waterproof and moisture-proof protection for the antenna assembly and other electronic components arranged in the mounting portion, preventing liquid, water vapor or dust particles from entering the antenna assembly or other electronic components and causing corrosion or short circuit, thereby extending their service life.

[0112] In one embodiment, a groove is formed between the mounting portion and the side of the front shell 310 , and the heat dissipation component is disposed in the groove.

[0113] In this embodiment, the heat dissipation component is disposed in a groove formed between the mounting portion and the side of the front shell 310, and is in contact with the sealing ring 360 and the front shell 310, respectively, so as to conduct the heat generated by the antenna assembly and other electronic components in the mounting portion during operation from the mounting portion to the heat dissipation component, and then conduct it to the front shell 310 and the air through the heat dissipation component, and finally conduct it to the air outside the front shell 310 through the larger area of ​​the front shell 310, thereby achieving a heat dissipation effect. Furthermore, thermally conductive silicone can be filled between the sealing ring 360 and the heat dissipation component and / or between the heat dissipation component and the front shell 310. Thermally conductive silicone can effectively fill the gaps in the contact surface and squeeze the air out of the contact surface. Air is a poor conductor of heat and will seriously hinder the transfer of heat between the contact surfaces. With the addition of thermally conductive silicone, the heat dissipation component can be fully in contact with the sealing ring 360 and the front shell 310 to achieve the smallest possible temperature difference and rapid heat dissipation.

[0114] The groove is also provided with multiple positioning posts and multiple screw posts. The multiple positioning posts are arranged in intervals on the groove corresponding to the positions of the heat sink assembly. The heat sink assembly is also provided with multiple positioning holes 377 at the positions corresponding to the positioning posts. The positioning posts penetrate the positioning holes 377 to secure the heat sink assembly to the groove, preventing the heat sink assembly from shifting and affecting the heat dissipation effect. Multiple screw posts are arranged in the groove, avoiding the position of the heat sink assembly. The screw posts are used to securely connect to the cover plate 350. The screw posts can be set in the gap of the heat sink assembly, using the space on the front shell 310 corresponding to the gap of the heat sink assembly, without affecting the performance of the antenna assembly.

[0115] This embodiment effectively conducts heat generated by the antenna assembly and other electronic components within the mounting portion by positioning the heat dissipation assembly within the groove formed between the mounting portion and the side of the front housing 310. Positioning posts can also be provided in the groove to secure the heat dissipation assembly, and screw posts can be provided to securely connect the front housing 310 to the cover 350. This eliminates the need for screw posts occupying the mounting portion, and allows for flexible positioning of the antenna assembly and electronic components such as the doorbell button, camera, and display within the mounting portion without requiring clearance.

[0116] In one embodiment, the heat dissipation component includes:

[0117] The first heat sink 341 is disposed outside the first cavity. Slots are provided on the heat sink, and the number and positions of the slots correspond to those of the antenna assembly.

[0118] In this embodiment, the heat dissipation assembly can be a one-piece heat sink with a slot provided on the heat sink corresponding to the antenna assembly, allowing the antenna assembly's signal to be transmitted through the slot. The slot has a width of no less than 1 mm. If there are multiple antenna assemblies, the number of slots should be the same as the number of antenna assemblies.

[0119] This embodiment provides a gap on the heat sink at a position corresponding to the antenna assembly so that the signal of the antenna assembly can be transmitted through the gap, thereby reducing the interference of the heat sink on the antenna assembly. The structure is simple, easy to implement, and does not affect the heat dissipation performance.

[0120] In one embodiment, the heat dissipation assembly includes:

[0121] The second heat sink 342 and the third heat sink 343 are spaced apart and arranged outside the first cavity, and the position of the gap formed between the second heat sink 342 and the third heat sink 343 corresponds to the antenna assembly.

[0122] In this embodiment, the heat dissipation assembly can be a separately designed second heat sink 342 and third heat sink 343. The gap formed between the second heat sink 342 and the third heat sink 343 corresponds to the antenna assembly, allowing the antenna assembly signal to be transmitted through the gap. The spacing between the second heat sink 342 and the third heat sink 343 is no less than 1 mm. Furthermore, the second heat sink 342 and the third heat sink 343 can also be provided with gaps, allowing the antenna signal to be transmitted through the gaps in the heat sinks.

[0123] In this embodiment, a gap is formed at the position corresponding to the antenna component by separately designed second heat sink 342 and third heat sink 343, so that the signal of the antenna component can be transmitted through the gap, reducing the interference of the heat sink on the antenna component. The structure is simple, easy to implement, and does not affect the heat dissipation performance.

[0124] In one embodiment, the gaps on the first heat sink 341 and the distances between the second heat sink 342 and the third heat sink 343 are greater than 1 mm.

[0125] In this embodiment, the gaps in the first heat sink 341 and the spacing between the second heat sink 342 and the third heat sink 343 are designed to ensure smooth signal transmission from the antenna assembly. If the gaps are too small, the antenna assembly's signals will not be transmitted smoothly. In this embodiment, the gaps in the first heat sink 341 and the spacing between the second heat sink 342 and the third heat sink 343 are set to be greater than 1 mm to ensure smooth signal transmission from the antenna assembly. It is understood that the larger the gaps in the first heat sink 341 or the spacing between the second heat sink 342 and the third heat sink 343, the less interference the heat sink will cause with the antenna assembly. However, since the area of ​​the heat sink is related to heat dissipation performance, achieving good heat dissipation performance requires a certain area. The gaps in the first heat sink 341 or the spacing between the second heat sink 342 and the third heat sink 343 can be adjusted according to actual needs to ensure good signal transmission while also ensuring that the heat sink has the required area to achieve its desired heat dissipation performance.

[0126] In one embodiment, the number of the second heat sink 342 and the number of the third heat sink 343 are both multiple;

[0127] Multiple second heat sinks 342 are arranged outside the first cavity along a first direction on the side of the front shell 310, and multiple third heat sinks 343 are arranged outside the first cavity along a second direction on the side of the front shell 310; wherein the first direction and the second direction are opposite.

[0128] In this embodiment, when there is only one antenna assembly, multiple second heat sinks 342 and multiple third heat sinks 343 are respectively disposed on either side of the antenna assembly. This allows the gaps between the multiple second heat sinks 342 and the gaps between the multiple third heat sinks 343 to transmit the antenna assembly's signal, thereby improving the antenna assembly's radiation performance in the electronic doorbell. When there are multiple antenna assemblies, the gaps between the multiple second heat sinks 342 or the gaps between the multiple third heat sinks 343 correspond to the number of antenna assemblies provided.

[0129] In one embodiment, the heat dissipation assembly further includes a fourth heat sink 344;

[0130] The fourth heat sink 344 is disposed outside the first cavity and away from the antenna assembly.

[0131] In this embodiment, the fourth heat sink 344 can be arranged opposite to the first heat sink 341. For antenna components with smaller sizes, such as the second antenna 332, a gap can be formed on the heat sink or between multiple heat sinks to transmit the signal of the antenna component. For antenna components with larger sizes, such as the first antenna 331, the width of the gap formed on the heat sink or between multiple heat sinks is limited, and the signal of the antenna component cannot be effectively transmitted. In this case, by setting the heat sink away from the antenna component, for example, referring to Figure 5 The radiating surface of the first antenna 331 is located on the left, and the fourth heat sink 344 is located on the right, so that the signal transmission of the first antenna 331 is not blocked by the fourth heat sink 344. Compared with a conventional one-piece heat sink design that fills one side of the groove, the area of ​​the fourth heat sink 344 is halved, reducing costs and minimizing the impact on the performance of the antenna assembly without affecting heat dissipation.

[0132] In one embodiment, the first heat sink 341 , the second heat sink 342 , the third heat sink 343 and the fourth heat sink 344 are curved structures to fit the front housing 310 .

[0133] In this embodiment, the first heat sink 341, the second heat sink 342, the third heat sink 343 and the fourth heat sink 344 are designed as a curved structure, which can not only increase the area of ​​the heat sink, but also fully fit with the front shell 310, so that the heat sink and the front shell 310 can be in face-to-face contact, further improving the heat dissipation efficiency.

[0134] In one embodiment, the antenna assembly includes a first antenna 331;

[0135] The first antenna 331 is arranged away from the fourth heat sink;

[0136] The first antenna 331 is used for long-distance communication with a mobile terminal.

[0137] In this embodiment, the first antenna 331 can be a LoRa antenna or a Zigbee antenna. Bluetooth antennas or WiFi antennas used for short-range communication are generally larger in size and have larger radiation surfaces. Forming gaps between the heat sinks still blocks most of the radiation surface of the first antenna 331, preventing effective signal transmission through the gaps. Therefore, in this embodiment, the first antenna 331 is positioned away from the fourth heat sink to ensure that the radiation surface of the first antenna 331 is not blocked by metal, thereby allowing electromagnetic waves to be smoothly transmitted / received.

[0138] In one embodiment, the antenna assembly includes a second antenna 332;

[0139] The second antenna 332 is disposed near a gap formed between the second heat sink 342 and the third heat sink 343 to transmit signals through the gap;

[0140] The second antenna 332 is used for short-range communication with a mobile terminal.

[0141] In this embodiment, the second antenna 332 may be a Bluetooth antenna or a WiFi antenna. Bluetooth antennas or WiFi antennas used for short-range communication are typically small in size and have a smaller radiating surface. In this embodiment, a gap is formed between the second heat sink 342 and the third heat sink 343 to ensure that the radiating surface of the second antenna 332 is not blocked by metal, thereby allowing electromagnetic waves to be smoothly transmitted and received through the gap between the second heat sink 342 and the third heat sink 343.

[0142] The present invention further provides an antenna, applicable to the first antenna 331, the second antenna 332, and the third antenna, the antenna comprising:

[0143] a first radiating portion 371;

[0144] The power feeding portion 373 and the ground feeding portion 374 are electrically connected to the first radiating portion 371 , respectively, and are disposed at an angle to the first radiating portion 371 .

[0145] In this embodiment, the electronic doorbell further includes an electronic control board 320, a front shell 310, and a cover plate 350. The cover plate 350 and the front shell 310 enclose a cavity for accommodating the antenna and the electronic control board 320. The antenna can be fixed to the front shell 310 by hot-melt bonding via the first radiating portion 371. The electronic control board 320 is disposed on the cover plate 350 or the front shell 310. When the cover plate 350 and the front shell 310 are enclosed, the electronic control board 320 abuts against the feed portion 373 and the ground feed portion 374, creating a certain pressure between the electronic control board 320, the feed portion 373, and the ground feed portion 374, thereby stabilizing the electrical contact between the antenna and the electronic control board 320 and preventing frequency deviation. Alternatively, the antenna can be fixed to the electronic control board 320 by welding the feed portion 373 and the ground feed portion 374, making it less likely for the antenna and the electronic control board 320 to shift.

[0146] The antenna of the present invention can be any one of a LoRa antenna, a Bluetooth antenna, a WiFi antenna, and a Zigbee antenna. The above antennas are all applicable to the structure of the present invention. For antennas of different types and frequency bands, the corresponding performance can be achieved by adjusting the shape of the first radiating portion 371. The electronic doorbell communicates with the mobile terminal through the antenna of the present invention, receives the control signal of the mobile terminal, or sends a data signal to the mobile terminal. For example, when the user performs an unlocking operation on the mobile terminal, the mobile terminal sends an unlocking control signal to the antenna of the electronic doorbell, and the antenna converts the received unlocking signal into a corresponding electrical signal and sends it to the electric control board 320, which then controls the corresponding functional circuit to unlock the door; when someone rings the doorbell, the electric control board 320 outputs a corresponding electrical signal to the antenna, and the antenna converts the received electrical signal into a corresponding visiting signal and sends it to the mobile terminal, so that the user can also receive the knocking information on the mobile terminal.

[0147] The power feed section 373 and ground feed section 374 are electrically connected to the power and ground feed points on the electronic control board 320, respectively, and the first radiating section 371 is positioned parallel to the electronic control board 320. When transmitting, the electronic control board 320 inputs a modulated high-frequency oscillating current into the antenna, generating electric and magnetic fields in the space surrounding the first radiating section 371. This converts the high-frequency oscillating current into radio waves (free electromagnetic waves) that are radiated into the surrounding space. When receiving, the electromagnetic waves radiate from the transmitting antenna and propagate in all directions. The electromagnetic waves generate an induced electromotive force in the first radiating section 371, converting the radio waves into a high-frequency oscillating current that is output to the electronic control board 320.

[0148] The feed section 373 and the ground feed section 374 are arranged at an angle to the first radiating section 371. The distance between the first radiating section 371 and the electronic control board 320 is related to the length of the feed section 373 and the ground feed section 374. When the electronic control board 320 is mounted on the front housing, the side edges of the electronic control board 320 can be fixed to the sidewalls of the front housing 310. By adjusting the height of the electronic control board 320 on the sidewalls of the front housing 310, the distance between the electronic control board 320 and the first radiating section 371 can be adjusted. As the distance between the electronic control board 320 and the first radiating section 371 increases, the length of the feed section 373 and the ground feed section 374 also increases, thereby increasing the height of the antenna. The antenna height can be adjusted by adjusting the length of the feed section 373 and the ground feed section 374, or their angle relative to the first radiating section 371, to achieve better antenna performance according to the needs of different products. Among them, the first radiation part 371, the feeding part 373 and the ground feeding part 374 can be formed in one piece, which has a short proofing cycle, saves debugging time and cost, and is convenient for mass production on the production line; or they can be formed by connecting multiple conductive components.

[0149] By arranging the power feed and ground feed at an angle to the first radiating portion, the present invention eliminates the need for planar space, reduces the antenna's footprint, and thus reduces the antenna's size. This allows for greater flexibility in installation within confined spaces and broadens its applicability. Besides electronic doorbells, the present invention can also be applied to other space-constrained products. By arranging the power feed and ground feed at an angle to the first radiating portion, the antenna's height can be adjusted by adjusting their lengths. This facilitates achieving a greater distance between the first radiating portion and the electronic control board, thereby improving antenna performance. The present invention can be applied to various designs of antenna heights relative to the electronic control board.

[0150] In one embodiment, the antenna further comprises:

[0151] The second radiating portion 372 is connected to the first radiating portion 371 , and the second radiating portion 372 and the first radiating portion 371 are arranged at an angle.

[0152] Generally speaking, the greater the antenna's height and radiation area, the better the antenna's performance. Therefore, in practical applications, the antenna's height is usually set as high as possible. The first radiating portion 371 and the second radiating portion 372 together constitute the antenna's radiation area. Adjusting the length of the second radiating portion 372 will change the antenna's radiation area. By adaptively adjusting the planar surface area of ​​the first radiating portion 371, the change in radiation area caused by the change in the height of the second radiating portion 372 can be compensated, ensuring that the antenna's radiation area meets performance requirements.

[0153] For example, increasing the length of the second radiating portion 372 increases the antenna's radiation area. In this case, the planar area of ​​the first radiating portion 371 can be reduced to maintain the same radiation area. Reducing the length of the second radiating portion 372 reduces the antenna's radiation area. In this case, the planar area of ​​the first radiating portion 371 can be increased to maintain the same radiation area. Furthermore, the shape of the first radiating portion 371 can be adjusted to achieve the desired resonance point and radiation efficiency based on the actual application. For example, a slit can be provided in the first radiating portion 371, or the first radiating portion 371 can be configured in a stepped shape to change the current distribution in the first radiating portion 371, thereby changing the electromagnetic field of the first radiating portion and adjusting the resonance point and radiation efficiency.

[0154] When setting the antenna height as high as possible within the limited internal space of the product, the plane area of ​​the first radiating portion 371 can be reduced accordingly, thereby ensuring the antenna performance while reducing the area occupied by the antenna.

[0155] This embodiment arranges the second radiating portion 372 at an angle to the first radiating portion 371. This arrangement eliminates the need for planar space, reduces the antenna's footprint, and consequently reduces the antenna's size. This allows for greater flexibility in installation within confined spaces and broadens its applicability. Besides electronic doorbells, the present invention can also be applied to other space-constrained products. By arranging the second radiating portion 372 at an angle to the first radiating portion 371, the antenna's height can be adjusted by adjusting the length of the second radiating portion. This facilitates achieving a greater distance between the first radiating portion and the electronic control board 320, thereby improving antenna performance. The present invention can be applied to various designs of antenna heights relative to the electronic control board 320.

[0156] The first radiating portion 371 , the second radiating portion 372 , the power feeding portion 373 and the ground feeding portion 374 are integrally formed.

[0157] In this embodiment, the first radiating portion 371, the second radiating portion 372, the feed portion 373, and the ground feed portion 374 are integrally formed, shortening the prototyping cycle, saving debugging time and costs, and facilitating mass production on the production line. Furthermore, the first radiating portion 371, the second radiating portion 372, the feed portion 373, and the ground feed portion 374 can be integrally formed using a single steel sheet. Compared to other metals, steel sheets are easy to form, readily available, and inexpensive, and the manufacturing process for integral molding is simple.

[0158] In one embodiment, the power feeding portion 373 and / or the ground feeding portion 374 extends from an end of the second radiating portion 372 in a direction parallel to the first radiating portion 371 .

[0159] In this embodiment, the feeding portion 373 and / or the ground feeding portion 374 extend from the end of the second radiating portion 372 in a direction parallel to the first radiating portion 371, forming an angle with the second radiating portion 372 and not perpendicular to the second radiating portion 372. If the feeding portion 373 and / or the ground feeding portion 374 are perpendicular to the second radiating portion, the feeding portion 373 and / or the ground feeding portion 374 will be in face-to-face contact with the electric control board when they abut. Since the feeding portion 373 and / or the ground feeding portion 374 and the electric control board are both hard objects, there may be gaps in the face-to-face contact, resulting in unstable electrical contact and thus unstable signal transmission. In this embodiment, the feeding portion 373 and / or the ground feeding portion 374 are set to be not perpendicular to the second radiating portion 372. In this way, the feeding portion 373 and / or the ground feeding portion 374 only needs to be electrically connected to the feeding point and / or feeding point on the electric control board 320 through a portion extending outward. Furthermore, the outwardly extending end of the feed portion 373 and / or ground feed portion 374 can be bent into a plane parallel to the first radiating portion and welded to the electronic control board 320 via this plane to achieve a stable face-to-face electrical connection. Alternatively, the outwardly extending end of the feed portion 373 and / or ground feed portion 374 can be provided with a protrusion, which can be used to achieve a point-to-face electrical connection with the electronic control board 320. Furthermore, the height of the antenna can be fine-tuned by adjusting the length of the feed portion 373 and ground feed portion 374 or the angle between them and the second radiating portion 372.

[0160] The power feeding portion 373 and / or the ground feeding portion 374 is provided with a bending portion toward the first radiating portion 371 .

[0161] In this embodiment, the power feed portion 373 and / or the ground feed portion 374 are bent in the direction toward the first radiating portion 371 to form a raised portion facing the electronic control board 320, and the raised portion abuts against the electronic control board 320. Furthermore, the bent portion can be a curved surface or a flat surface to ensure smoother contact with the electronic control board 320.

[0162] In one embodiment, the bent portion is provided with a metal bump 275 .

[0163] In this embodiment, metal bumps 275 are provided on the side of the bent portion facing the electronic control board 320 to achieve point-to-surface electrical contact with the electronic control board 320. It will be appreciated that the contact surfaces of the electronic control board 320 and the bent portion are both made of hard metal. Surface-to-surface contact between hard metals cannot be completely aligned, and gaps will always exist, resulting in unstable electrical contact between the antenna and the electronic control board 320 and unnecessary energy loss during electrical signal transmission.

[0164] In this embodiment, a metal bump 275 is provided on the bent portion to achieve a more stable point-to-surface electrical contact with the electric control board 320 , thereby improving the consistency of the antenna.

[0165] In one embodiment, the power feeding portion 373 and / or the ground feeding portion 374 is an elastic member.

[0166] In this embodiment, because the feed portion 373 and the ground feed portion 374 form an angle with the second radiating portion 372, and this angle is not 90°, the feed portion 373 and / or the ground feed portion 374 are configured as elastic members, allowing for movement between the feed portion 373 and the ground feed portion 374 and the second radiating portion 372. When the feed portion 373 and / or the ground feed portion 374 abut the electronic control board 320, they are displaced downward by a certain angle due to pressure from the electronic control board 320. Simultaneously, their own elastic force also generates a reaction force on the electronic control board 320, creating a certain amount of static friction between the feed portion 373 and / or the ground feed portion 374 and the electronic control board 320, preventing displacement and ensuring more stable contact. The front-to-back distance and height of the feed portion 373 and / or the ground feed portion 374 can be adjusted according to actual needs to achieve the desired elasticity.

[0167] In one embodiment, the first radiating portion 371 and the second radiating portion 372 are disposed at an angle of 90°.

[0168] In this embodiment, when the electronic control board 320 abuts the power feed portion 373 and / or ground feed portion 374, the power feed portion 373 and / or ground feed portion 374 are displaced, causing them to exert pressure on the second radiating portion 372. Because the angle between the power feed portion 373 and / or ground feed portion 374 and the second radiating portion 372 is not 90°, the pressure F exerted by the power feed portion 373 and / or ground feed portion 374 on the second radiating portion 372 can be decomposed into a vertical component F1 and a horizontal component F2, where the horizontal direction is parallel to the first radiating portion 371. If the first radiating portion 371 and the second radiating portion 372 are not arranged at a 90° angle, the vertical component F1 will cause the first radiating portion to displace closer to the first radiating portion, thereby reducing the height of the antenna. Furthermore, the height of the second radiating portion 372 is not less than 6 mm. If the height of the second radiating portion is too low, the radiation performance of the antenna will be affected. In practical applications, the area of ​​the first radiating portion can be adaptively adjusted to set the height of the second radiating portion 372 higher.

[0169] In this embodiment, by arranging the first radiating portion 371 and the second radiating portion 372 perpendicularly, the vertical component F1 of the power feed portion 373 and / or the ground feed portion 374 on the second radiating portion 372 can be offset, preventing vertical displacement of the second radiating portion 372 and ensuring stable antenna performance. Furthermore, by arranging the first radiating portion 371 and the second radiating portion 372 perpendicularly, the height variation of the second radiating portion 372 is the same as the height variation of the antenna, facilitating more direct adjustment of the antenna height.

[0170] In one embodiment, the antenna further comprises:

[0171] The fixing portion 376 is disposed on both sides of the second radiating portion 372 and is disposed at an angle with the first radiating portion 371 and the second radiating portion 372 . The fixing portion 376 is used to fix the antenna on an object to be installed.

[0172] The pressure of the feeding part 373 and / or the ground feeding part 374 on the second radiating part 372 will produce a horizontal component, causing the second radiating part 372 to be displaced in the horizontal direction, thereby causing the contact point of the feeding part 373 and / or the ground feeding part 374 to be displaced. In this embodiment, by providing a fixing part 376 on both sides of the second radiating part 372, which is arranged at an angle to the first radiating part 371 and the second radiating part 372, the position of the second radiating part 372 in the horizontal direction is fixed, thereby avoiding displacement that affects the electrical contact between the antenna and the electronic control board 320. The angle between the fixing part 376 and the first radiating part 371 and the second radiating part 372 can be 60°, 90° or 120°, which is not limited here. Specifically, the fixing part 376 can be a solid plane with a limiting hole, and the positioning column on the installed object passes through the limiting hole to fix its position; or, the fixing part 376 can be arranged in an L shape, such as Figure 1 As shown. One end of the fixing portion 376 is bent at 90 degrees, and a positioning hole 377 is provided on the bent portion. The positioning post on the mounted object passes through the positioning hole 377 to fix its position. The fixing portion 376 can be bent toward the feeding portion 373 and / or the ground feeding portion 374, or can be bent away from the feeding portion 373 and / or the ground feeding portion 374. The bent end of the fixing portion 376 can be an end close to the feeding portion 373 and / or the ground feeding portion 374, or an end close to the first radiating portion 371. The fixing portion 376 can be integrally formed with the first radiating portion 371, the second radiating portion 372, the feeding portion 373 and the ground feeding portion 374, or can be separately fixed to the second radiating portion 372.

[0173] The present invention further provides an antenna assembly, comprising:

[0174] the aforementioned antenna;

[0175] An antenna bracket, wherein a positioning column is provided on the antenna bracket;

[0176] The fixing portion of the antenna is provided with a positioning hole 377 , and the positioning post passes through the positioning hole 377 on the fixing portion of the antenna.

[0177] In this embodiment, the antenna bracket includes a flat base to which the second radiating portion 372 of the antenna can fit, thereby securing and supporting the antenna. Positioning posts are provided on the base surface corresponding to the positions of the antenna's positioning holes 377, and there are multiple positioning posts.

[0178] The detailed structure of the antenna assembly can be referred to the above-mentioned embodiment and will not be repeated here. It can be understood that since the above-mentioned antenna is used in the antenna assembly of the present invention, the embodiment of the antenna assembly of the present invention includes all technical solutions of all the embodiments of the above-mentioned antenna, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0179] The above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
