Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a doorbell bracket, doorbell system and door component. Background Technology

[0002] A smart doorbell is a doorbell device that enables remote, real-time interaction with mobile phones or other mobile devices through network connectivity, sensor technology, and intelligent control. It combines the functions of a traditional peephole and doorbell, and can provide 24 / 7 monitoring. Smart doorbells can communicate with visitors not only through video and voice, but also use a mobile application to synchronize any unusual situations with the user.

[0003] In related technologies, smart doorbells generally include a main unit and a receiver. The main unit, equipped with an antenna, is located outdoors, while the receiver and the router providing the network are located indoors.

[0048] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] A smart doorbell is a doorbell device that enables remote, real-time interaction with mobile phones or other mobile devices through network connectivity, sensor technology, and intelligent control. It combines the functions of a traditional peephole and doorbell, and can provide 24 / 7 monitoring. Smart doorbells can communicate with visitors not only through video and voice, but also use a mobile application to synchronize any unusual situations with the user.

[0050] In related technologies, smart doorbells generally include a main unit and a receiver. The main unit, equipped with an antenna, is located outdoors, while the receiver and the router providing the network are located indoors. The antenna is separated from the receiver and the router by at least one wall or door, resulting in poor signal transmission and easy signal attenuation or disconnection. This leads to increased power consumption of the main unit, shortened standby time, increased charging frequency for users, or renders the smart doorbell unusable, affecting the user experience.

[0051] To address the aforementioned technical problems, this application provides a doorbell bracket, a doorbell system, and a door component.

[0052] like Figures 1 to 3 As shown in the figure, the doorbell bracket provided in this application embodiment includes a bracket body 1, a connecting component 2, and a communication component 3.

[0053] The communication component 3 has an antenna 32. The connection component 2 is used to connect the support body 1 and the communication component 3, and the connection component 2 is electrically connected to the antenna 32.

[0054] The bracket body 1 is used to install the main unit of the doorbell system. For example, the main unit is installed on the bracket body 1 by means of buckles, slides, etc. This application does not specifically limit the connection method between the main unit and the bracket body 1.

[0055] Exemplarily, the connecting component 2 has an electrical interface on the side near the bracket body 1. This electrical interface is adapted to be electrically connected to the main unit, thereby enabling an electrical connection between the main unit and the antenna 32, which serves as an extension antenna for the main unit. Exemplarily, the main unit includes electronic devices such as a camera, infrared sensor, microwave sensor, call button, speaker, and microphone. The main unit can detect and record visitors, providing remote monitoring functionality. The antenna 32 enables wireless and internet communication, allowing the main unit to connect to a home network for remote monitoring and control. The doorbell system also includes a receiver installed in the indoor environment. The main unit communicates with the receiver via the antenna 32. When the main unit triggers an event, the receiver provides the user with visual or auditory alerts, or initiates voice or video calls.

[0056] The bracket body 1 is located on the first side of the connecting component 2, and the communication component 3 is located on the second side of the connecting component 2. For example... Figure 2 or Figure 3 As shown, the connecting component 2 is adapted to be inserted into the through hole 101 on the door body 100.

[0057] The door 100 is used to distinguish between the indoor and outdoor environments. The first and second sides of the connecting component 2 are located on opposite sides of the thickness of the door 100. Specifically, the first and second sides of the connecting component 2 correspond to the outdoor and indoor environments, respectively. That is, the main unit on the bracket body 1 is located in the outdoor environment, and the antenna 32 is located in the indoor environment. Optionally, the connecting component 2 can also be installed in the through hole 101 of the door frame or wall.

[0058] In traditional doorbell systems, the main unit's bracket is often installed on doors, walls, door frames, etc., using adhesive backing. Over time, this can easily lead to detachment and is not conducive to repeated installation. The doorbell bracket provided in this application embodiment can mechanically fix the bracket body 1 to the door body 100 by inserting the connecting component 2 through the through hole 101 on the door body 100. This improves the installation reliability and stability of the bracket body 1 and allows for repeated installation.

[0059] For example, the through hole 101 on the door 100 is a peephole. By using the existing peephole on the door 100 to install the doorbell bracket, no additional hole needs to be drilled, which improves the ease of installation and applicability of the doorbell bracket. Optionally, the through hole 101 on the door 100 can also be a hole other than a peephole.

[0060] The doorbell bracket provided in this application embodiment is such that the bracket body 1 and the communication component 3 are connected by the connecting component 2, so the bracket body 1 and the communication component 3 can be located on both sides of the door 100 respectively. When the bracket body 1 is located outside the door, the communication component 3 is located inside the door. The bracket body 1 can be used to install the host, which facilitates the host to communicate with devices such as routers and receivers through the antenna 32 located inside the door. This reduces the impact of doors and walls on signal transmission, which is beneficial to improving the signal transmission effect and signal strength between the host and devices such as routers and receivers, reducing the power consumption of the host, reducing the frequency of user charging, and improving the user experience.

[0061] In a further embodiment, a first connecting hole 11 is provided on the support body 1, and the first connecting hole 11 penetrates the support body 1 along the thickness direction of the support body 1. Figure 5 and Figure 6 As shown, the connecting assembly 2 includes a sleeve 21 and a circuit board 22. The sleeve 21 is inserted into the first connecting hole 11 and has a receiving cavity 211. The circuit board 22 is at least partially located within the receiving cavity 211. A first connecting contact point 221 is provided on the first side of the circuit board 22, and a connecting cable 222 for electrical connection with the antenna 32 is provided on the second side of the circuit board 22. The first connecting contact point 221 is electrically connected to the connecting cable 222. That is, the first connecting contact point 221 is the electrical interface of the connecting assembly 2.

[0062] like Figure 7 or Figure 8 As shown, the sleeve 21 is cylindrical, and the receiving cavity 211 extends through the sleeve 21 along its length. Optionally, as... Figure 8 As shown, the accommodating cavity 211 includes a large-diameter cavity and a small-diameter cavity that are connected to each other, and the accommodating cavity 211 is stepped. Figure 9 As shown, the sleeve 21 has a first mounting hole 214 at one end where the small diameter cavity is located. Bolts, screws and other threaded fasteners pass through the communication component 3 and the first mounting hole 214 in sequence to connect the connecting component 2 and the communication component 3.

[0063] The first side and the second side of the circuit board 22 are two sides in the thickness direction of the circuit board 22, such as Figure 10 As shown, the left side of the circuit board 22 is the first side, and the first contact point 221 is disposed on the left surface of the circuit board 22. The right side of the circuit board 22 is the second side, and the connecting cable 222 extends on the right side of the circuit board 22.

[0064] When the length of the connecting cable 222 is relatively long, the connecting cable 222 can be accommodated in the receiving cavity 211, reducing the space occupied by the connecting cable 222.

[0065] For example, the first contact point 221 is a flexible movable contact, which is used to electrically connect with the host, thereby realizing the electrical connection between the host and the communication component 3.

[0066] Furthermore, such as Figure 10 As shown, the end of the connecting cable 222 is provided with a second contact point 2221, as follows: Figure 11 As shown, the communication component 3 includes a backplate 31 and an antenna 32 disposed on the backplate 31. A terminal block 321 is disposed on the backplate 31. The second contact point 2221 is electrically connected to the terminal block 321, thereby realizing the electrical connection between the connecting cable 222 and the antenna 32.

[0067] Connecting cable 222 can be one or more, such as Figure 10 As shown, there are two connecting cables 222, and each connecting cable 222 has a second contact point 2221 at its end.

[0068] For example, the antenna 32 is an antenna circuit board, and the antenna 32 is fixed to the back plate 31 by means of threaded fasteners, adhesive, heat fusion, snap-fit, etc. Alternatively, the antenna 32 is a rod antenna, and the antenna 32 is fixed on the side of the back plate 31 facing the indoor environment, and has a certain position adjustment function.

[0069] The backplate 31 can be rectangular, circular, elliptical, triangular, or other shapes, for example... Figure 11 As shown, the back panel 31 is rectangular and is adapted to abut against the surface of the door 100.

[0070] The back plate 31 has a second mounting hole 314. Align the second mounting hole 314 with the first mounting hole 214 on the sleeve 21, and then pass the threaded fastener through the second mounting hole 314 and the first mounting hole 214 in sequence and tighten it to realize the connection between the connection component 2 and the communication component 3, and complete the installation and fixation of the main unit doorbell bracket.

[0071] like Figure 11 As shown, two terminal blocks 321 are provided on one side surface of the backplate 31. The two terminal blocks 321 are electrically connected to the second contact point 2221 at the end of the connecting cable 222, and the terminal blocks 321 are electrically connected to the antenna 32. Thus, the electrical connection between the circuit board 22 and the antenna 32 is realized, and the electrical connection between the host and the antenna 32 is realized.

[0072] In one specific embodiment, the back plate 31 has a receiving slot 312, and the antenna 32 is placed in the receiving slot 312.

[0073] like Figure 11As shown, the back plate 31 is recessed with two receiving slots 312, and each receiving slot 312 is provided with a terminal block 321. The antenna 32 is an antenna circuit board and the antenna 32 is in the shape of a sheet. The receiving slots 312 are used to accommodate the antenna 32, provide an installation position for the antenna 32, and at the same time reduce the space occupied by the antenna 32 in the thickness direction of the back plate 31, thereby improving the space utilization of the back plate 31.

[0074] Furthermore, there are multiple receiving slots 312, and the back plate 31 is provided with a cable groove 313, and at least two adjacent receiving slots 312 are connected through the cable groove 313.

[0075] The cable tray 313 is used to fix the connecting cable 222 and organize the path of the connecting cable 222, so as to prevent the connecting cables 222 from getting tangled and affecting installation or disassembly. By setting at least two adjacent receiving slots 312 to be connected by the cable tray 313, the same cable tray 313 can be used to organize the wire harness of at least two adjacent receiving slots 312, making the doorbell bracket structure more compact and neat.

[0076] Specifically, such as Figure 11 As shown, there are two receiving slots 312, and a cable slot 313 is located between the two receiving slots 312, and the cable slot 313 is connected to both receiving slots 312 respectively. In this embodiment, the first end of the cable slot 313 is connected to the first receiving slot 312, and the second end is connected to the second receiving slot 312, which can accommodate the connecting cable 222 connected to the two receiving slots 312 in the same cable slot 313, making the structure of the communication component 3 more compact and neat.

[0077] In one embodiment, one end of the sleeve 21 is provided with a flange portion 212, the flange portion 212 is provided with a second connecting hole 2121 communicating with the receiving cavity 211, the bracket body 1 is provided with a recess 12 for receiving the flange portion 212, the flange portion 212 is provided with a first limiting structure 2122, the recess 12 is provided with a first mating structure 121, and the first limiting structure 2122 and the first mating structure 121 are mated and connected.

[0078] like Figures 7 to 9 As shown, a flange 212 is provided at one end of the sleeve 21 where the large-diameter cavity is located. The flange 212 is annular and protrudes outward relative to the outer wall of the sleeve 21.

[0079] like Figure 4 As shown, the recess 12 is located on the outer periphery of the first connecting hole 11. The recess 12 is annular, and its shape and size are adapted to the shape and size of the flange portion 212. Optionally, when the flange portion 212 is accommodated in the recess 12, the end face of the flange portion 212 is flush with the inner wall of the bracket body 1, thereby reducing the space occupied in the thickness direction of the bracket body 1.

[0080] One of the first limiting structure 2122 and the first mating structure 121 is a protrusion, and the other is a groove. The protrusion is inserted into the groove, thereby restricting the relative rotation between the sleeve 21 and the bracket body 1. For example Figure 4 and Figure 9 As shown, the first limiting structure 2122 is a protrusion, and the first mating structure 121 is a groove disposed in the recess 12; or, the first limiting structure 2122 is a groove disposed on the flange portion 212, and the first mating structure 121 is a protrusion disposed in the recess 12. It can be understood that the first limiting structure 2122 and the first mating structure 121 can be one or more, for example... Figure 4 and Figure 9 As shown, there is one first limiting structure 2122 and one first mating structure 121.

[0081] Furthermore, the connecting assembly 2 also includes a pressure plate 23, which is located within the second connecting hole 2121 and has an insertion hole 231 for the first connecting contact point 221 to pass through. A support plate 213 is formed by protrusions on the inner wall of the sleeve 21, which is located within the receiving cavity 211 and is used to support the circuit board 22.

[0082] like Figure 12 As shown, the pressure plate 23 is circular. The pressure plate 23 is accommodated within the second connecting hole 2121 and covers one end opening of the accommodating cavity 211. Exemplarily, the shape and size of the pressure plate 23 are adapted to the shape and size of the second connecting hole 2121, so that the pressure plate 23 is precisely accommodated within the second connecting hole 2121.

[0083] The socket 231 extends through the pressure plate 23 along its thickness direction, and the first contact point 221 can pass through the socket 231, thereby connecting to the main unit. The number of sockets 231 can be one or more; for example, there can be one socket 231, allowing multiple first contact points 221 to pass through; or, as... Figure 12 As shown, there are multiple sockets 231, and each socket 231 allows one connection point to pass through. For example... Figure 6 As shown, by setting the pressure plate 23 and the support plate 213, the circuit board 22 is supported and limited, preventing the circuit board 22 from moving inside the sleeve 21; by setting the insertion hole 231, the first connection contact point 221 can be extended outside the pressure plate 23, which facilitates the connection of the first connection contact point 221 with the main unit.

[0084] like Figure 8 As shown, the support plate 213 protrudes inward relative to the inner wall of the accommodating cavity 211, and there is a gap between the support plate 213 and the inner wall on the opposite side, which does not affect the spatial communication between the two sides of the support plate 213 in the thickness direction.

[0085] like Figure 6 As shown, the circuit board 22 is located in the accommodating cavity 211. The left side of the circuit board 22 abuts against the pressure plate 23, and the right side of the circuit board 22 abuts against the support plate 213. Under the combined action of the pressure plate 23 and the support plate 213, the circuit board 22 maintains a stable position in the accommodating cavity 211 without shifting, thus improving the stability of the circuit board 22.

[0086] Furthermore, the size of the second connecting hole 2121 is larger than the opening size of the accommodating cavity 211, thereby forming a step at the connection between the flange 212 and the sleeve 21, and the pressure plate 23 is installed at the step.

[0087] like Figure 8 As shown, the diameter of the second connecting hole 2121 is larger than the diameter of the opening at the left end of the accommodating cavity 211, thereby forming an annular step at the connection between the flange 212 and the sleeve 21. The step provides an installation position for the pressure plate 23. One side surface of the pressure plate 23 abuts against the surface of the step, reducing the space occupied by the pressure plate 23 in the axial direction of the sleeve 21, and improving the connection reliability between the pressure plate 23 and the sleeve 21.

[0088] Furthermore, a second limiting structure 24 is provided at the step, and a second mating structure 232 is provided on the side surface of the pressure plate 23 near the receiving cavity 211. The second limiting structure 24 and the second mating structure 232 are mated and connected.

[0089] One of the second limiting structure 24 and the second mating structure 232 is a protrusion, and the other is a groove. The protrusion is inserted into the groove, thereby restricting the relative rotation between the pressure plate 23 and the sleeve 21. For example Figure 7 and Figure 12 As shown, the second limiting structure 24 is a groove formed at the step, and the second limiting structure 24 extends into the receiving cavity 211. The second mating structure 232 is a protrusion provided on one side surface of the pressure plate 23; or, the second limiting structure 24 is a protrusion provided at the step, and the second mating structure 232 is a groove provided on one side surface of the pressure plate 23. It can be understood that the second limiting structure 24 and the second mating structure 232 can be one or more, for example... Figure 12 As shown, there are two second mating structures 232, and two corresponding second limiting structures 24.

[0090] In one embodiment, the doorbell bracket further includes a threaded component. A protruding post 233 is provided on one side surface of the pressure plate 23. The protruding post 233 abuts against the circuit board 22. The protruding post 233 has a first threaded hole 2331. The circuit board 22 has a second threaded hole 223. The support plate 213 has a third threaded hole 2131. The threaded component is sequentially inserted into the third threaded hole 2131, the second threaded hole 223 and the first threaded hole 2331. It is simple to operate, has good connection and fastening, and is easy to disassemble and assemble.

[0091] Threaded components include bolts, screws, and other threaded fasteners. The protrusion 233 abuts against the left side of the circuit board 22. Under the combined action of the protrusion 233 and the support plate 213, the circuit board 22 maintains a stable position within the accommodating cavity 211 without shifting, thus improving the stability of the circuit board 22.

[0092] This application embodiment also provides a door assembly, which includes a door body 100 and a doorbell bracket provided in any of the above embodiments, such as... Figure 2 As shown, the door body 100 has a through hole 101, and the connecting component 2 of the doorbell bracket is inserted into the through hole 101. The bracket body 1 and the communication component 3 of the doorbell bracket are located on the indoor and outdoor sides of the door body 100, respectively.

[0093] The door assembly provided in this application embodiment has a bracket body 1 and a communication component 3 located on opposite sides of the door 100. When the bracket body 1 is located outside the door, the communication component 3 is located inside, facilitating communication with devices such as routers and receivers. This reduces the impact of doors and walls on signal transmission, improves the signal transmission effect and signal strength between the bracket body 1 and devices such as routers and receivers, reduces the power consumption of the bracket body 1, reduces the frequency of user charging, and improves the user experience.
