Description

Technical Field

[0001] This utility model relates to the field of doorbell technology, and in particular to a smart doorbell with dual power supply mode. Background Technology

[0002] Doorbells, as convenient and practical products, are widely used in various households. In related technologies, smart doorbells generally include a doorbell host and a wall-mounting panel. The doorbell host is installed in the wall-mounting panel and connected to the power supply via a wired connection. However, the inventors found in the actual research and development process that this type of smart doorbell using a single power supply cannot be used in the event of a power outage, which limits the usage scenarios and leads to a less than ideal user experience.

[0003] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a smart doorbell with dual power supply mode, which effectively solves the technical defects of existing smart doorbells using a single power supply, which limit the application scenarios, thereby improving the reliability of the smart doorbell and the user experience.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a smart doorbell with dual power supply modes, comprising...

[0006] Base assembly; and,

[0007] The doorbell main unit is detachably installed on the base assembly. The doorbell main unit has a hollow main unit shell, and a first connection terminal is provided on the rear surface of the main unit shell. The first connection terminal extends rearward from the inside of the main unit shell and is exposed on the rear surface of the main unit shell. A circuit board, a camera module connected to the circuit board, an infrared sensing module connected to the circuit board, a touch module connected to the circuit board, and a battery module connected to the circuit board are installed inside the main unit shell. The circuit board is provided with a first elastic contact terminal for contacting the first connection terminal.

[0008] The beneficial effect of the dual-power supply mode smart doorbell provided in this application is that, compared with the prior art,

In different scenarios, the reliability of the smart doorbell and the user experience can be guaranteed.

[0010] Secondly, wired power supply avoids frequent battery charging and discharging. For doorbells with complex functions and high power consumption, such as smart doorbells that frequently use cameras, relying solely on battery power would accelerate battery aging due to frequent charging and discharging.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] Please refer to the following: Figures 1 to 5 The present application will now describe a smart doorbell with dual power supply mode according to an embodiment. The smart doorbell with dual power supply mode includes: a base assembly 10 and a doorbell main unit 20.

[0043] The base assembly 10 is used for mounting on a support, including but not limited to a wall or door. The doorbell main unit 20 can be detachably mounted on the base assembly 10. The doorbell main unit 20 has a hollow main unit housing. A first connection terminal 21 is provided on the rear surface of the main unit housing. The first connection terminal 21 extends rearward from the inside of the main unit housing and is exposed on the rear surface of the main unit housing. A circuit board, a camera module 22 connected to the circuit board, an infrared sensing module 23 connected to the circuit board, a touch module 24 connected to the circuit board, and a battery module 25 connected to the circuit board are installed inside the main unit housing. The circuit board is provided with a first elastic contact terminal 261 for contacting the first connection terminal 21.

[0044] Specifically, in the first aspect, by setting a first connection terminal 21 connected to the circuit board and a battery module 25, dual power supply modes can be provided for the camera module 22, infrared sensing module 23, and touch module 24; the first connection terminal 21 can be connected to the mains power, providing a continuous and stable power supply; the battery module 25 provides additional protection, in the event of a fault in the wired power line, such as a damaged wire or unstable voltage, the battery can take over the power supply in time to maintain the basic functions of the smart doorbell; in different scenarios, the reliability of the smart doorbell and the user experience can be guaranteed.

[0045] Secondly, wired power supply avoids frequent battery charging and discharging. For doorbells with complex functions and high power consumption, such as smart doorbells that frequently use cameras, relying solely on battery power would accelerate battery aging due to frequent charging and discharging. In dual power supply mode, when the wired power supply is working normally, the frequency of battery use can be reduced, thereby extending battery life and lowering the cost and frequency of battery replacement for users.

[0046] In some embodiments, the main housing includes a bottom shell 201 and a front cover 202. After the bottom shell 201 and the front cover 202 are assembled together, they can form a mounting cavity 203 for mounting components. A first connecting terminal 21 is disposed on the bottom shell 201, a circuit board is disposed on the front cover 202, and a first elastic contact terminal 261 is disposed on the rear side of the circuit board. After the front cover 202 is installed on the bottom shell 201, the first elastic contact terminal 261 can contact the first connecting terminal 21.

[0047] Specifically, the circuit board includes a first circuit board 26 and a second circuit board 27 disposed on the front cover 202. The second circuit board 27 is spaced apart from the first circuit board 26 and is located at the top of the mounting cavity 203. The camera module 22 is disposed on the front surface of the first circuit board 26 and exposed on the front cover 202. The infrared sensing module 23 is disposed on the front surface of the second circuit board 27 and exposed on the front cover 202. The first elastic contact terminal 261 is disposed on the rear surface of the first circuit board 26. The second circuit board 27 is electrically connected to the first circuit board 26.

[0048] It is understandable that by installing the first circuit board 26 and the second circuit board 27 on the front cover, integrating the camera module 22 on the first circuit board 26, and integrating the infrared sensing module 23 on the second circuit board 27, these components can be pre-installed on the front cover 202. After the front cover 202 and the bottom cover 201 are assembled together, the first elastic contact terminal 261 of the first circuit board 26 can contact the first connection terminal 21, so that the mains power can be connected through the first connection terminal 21 to provide mains power to the camera module 22 and the infrared sensing module 23. There is no need to perform wiring work before assembling the front cover 202 and the bottom cover 201, which helps to reduce the assembly difficulty, thereby improving the production efficiency of the smart doorbell, and also facilitates the user's later maintenance.

[0049] More specifically, the second circuit board 27 is provided with a first clearance opening 271, through which the camera module 22 can extend forward and be exposed on the front cover 202. This structure allows for the front-to-back spacing between the second circuit board 27 and the first circuit board 26, and also allows for the installation of the camera module 22 and the infrared sensing module 23, significantly reducing their installation footprint and further reducing the overall size of the smart doorbell, which is beneficial for the development of miniaturized smart doorbells.

[0050] Furthermore, the circuit board also includes a third circuit board 28 disposed on the front cover 202, the third circuit board 28 being disposed on the front cover 202 and located at the bottom of the mounting cavity 203; the touch module 24 is disposed on the front surface of the third circuit board 28 and exposed on the front cover 202, and the third circuit board 28 is electrically connected to the first circuit board 26.

[0051] In other embodiments, a first recess 2011 is provided on the rear surface of the bottom shell 201, and a first connecting terminal 21 extends rearward and is exposed in the first recess 2011. The first connecting terminal 21 is screwed with a first screw 211 for fastening the cable. Before the doorbell host 20 is installed on the base assembly 10, one end of the cable is connected to the mains power supply, and the other end of the cable is screwed to the first connecting terminal 21 by the first screw 211. Then, through the conductive connection between the first connecting terminal 21 and the first elastic contact terminal 261, power can be provided to electronic components such as the camera module 22, infrared sensing module 23, and touch module 24.

[0052] Specifically, the base assembly 10 includes a silicone base 11 and a metal support plate 12 disposed on the rear surface of the silicone base 11. The silicone base 11 is provided with a through hole 111 through which screws can pass and be screwed to the support. The silicone base 11 is provided with a silicone enclosure 112. When the bottom shell 201 is snapped onto the silicone base 11, the silicone enclosure 112 can cover the rear surface of the bottom shell 201.

[0053] Furthermore, the bottom left and right sides of the rear surface of the bottom shell 201 are provided with first fastening notches 2012, and the silicone enclosure 112 is provided with first fastening protrusions 113 for fastening into the first fastening notches 2012; the top of the rear surface of the bottom shell 201 is provided with a first elastic fastening block 2013, and the top of the silicone enclosure 112 is provided with a first fastening window 114 for fastening into the first elastic fastening block 2013. The installation process of the smart doorbell is as follows: First, the metal support plate 12 is attached to the rear surface of the silicone base 11, and then the silicone base 11 is fastened to the support with screws; next, the bottom of the doorbell host 20 is inserted into the silicone base 11, and the first snap-fit ​​protrusion 113 is snapped into the first snap-fit ​​notch 2012; finally, the top of the doorbell host 20 is inserted into the silicone base 11, so that the first elastic buckle 2013 is snapped into the first snap-fit ​​window 114, so that the silicone enclosure 112 of the silicone base 11 completely covers the rear surface of the bottom shell 201, thereby preventing external liquids from seeping into the first connection terminal 21 and the cable from the edge of the bottom shell 201, thereby improving the power connection safety of the mains power supply.

[0054] Understandably, the top of the silicone enclosure 112 is provided with an insertion hole, which can be exposed at the position of the first elastic buckle inside; when it is necessary to disassemble the doorbell host, a column smaller than the diameter of the insertion hole is provided, the column is inserted into the insertion hole and the first elastic buckle is moved down, so that the first elastic buckle can be disengaged from the first fastening window, thereby removing the doorbell host from the silicone seat.

[0055] Preferably, the bottom shell 201 is provided with a first window 2014, and the first window 2014 is movably provided with a first dust plug 2015; the first circuit board 26 integrates a type-C interface 262 and an SD card interface 263, which can be exposed through the first window 2014; the silicone enclosure 112 is provided with a first extended abutment part 115 that can abut against the first dust plug 2015. Through the provided type-C interface 262, users can connect external devices to read the data stored in the camera module 22, and when the mains power and battery module 25 are unable to provide power, an external power bank can be connected through the type-C interface 262 for emergency power supply; the SD card interface 263 can insert an SD data card to save the data of the camera module 22.

[0056] Furthermore, it also includes a speaker module 29 installed on the front cover 202, which is wiredly connected to the first circuit board 26.

[0057] It is understandable that the wired connections between the first and second circuit boards, the third circuit board and the first circuit board, and the speaker module and the first circuit board are connected using FPC cables.

[0058] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
