Description

Technical Field

[0001] This utility model belongs to the field of doorbell technology, and specifically relates to a novel video doorbell. Background Technology

[0002] Video doorbells, as an effective security product, are gradually becoming an important choice for many residential building residents to improve home security. Video doorbells collect visitor information through a camera and transmit this information to the resident's mobile device, allowing residents to know what's happening at their door even when they are not home, thus improving convenience and security. However, existing video doorbells have some shortcomings. First, traditional video doorbells can usually only capture half-body photos of visitors, unable to capture full-body shots. This is mainly due to the unreasonable installation angle design of the lens, resulting in a limited vertical field of view. To overcome this problem, existing technology proposes a solution: expanding the shooting range by driving the camera up and down to achieve a full-body shot. However, this method increases the overall structural complexity of the video doorbell, not only increasing the device size but also, due to the limited lens installation angle, still having blind spots, unable to capture a complete view around the lens. For ordinary users, the complex structure means inconvenient disassembly, assembly, and maintenance costs, increasing usage costs and reducing user experience due to the inconvenience of disassembly and assembly. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of video doorbell. By providing an improved structural design of the plane on which the lens is located, the lens can capture the whole body and is installed in a way that better meets the user's multifunctional needs for a visual doorbell.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A novel video doorbell includes: a doorbell body, the front end face of the doorbell body having a first plane, a first inclined plane and a second plane from top to bottom, the first plane being parallel to the second plane, the first inclined plane being inclined inward from top to bottom, the height of the first plane being greater than the height of the second plane, and the two ends of the first inclined plane being smoothly connected to the first plane and the second plane.

[0005] The mounting bracket is located inside the doorbell body. The mounting bracket includes a first mounting bracket and a second mounting bracket. The first mounting bracket includes a vertically arranged mounting base and an inclined bracket. The end face of the inclined bracket is parallel to the first inclined surface. The second mounting bracket is fixed to the end face of the inclined bracket. The lens can pass through the first inclined surface and is fixed to the end face of the second mounting bracket. The infrared sensor is disposed on the end face of the second mounting bracket.

[0006] Compared to existing technologies, the advantages of this invention are as follows: The visual doorbell proposed in this invention, by setting a first inclined surface located between a first plane and a second plane, gives the front face of the entire doorbell body a downward tilted viewing angle. When the lens is embedded in the front face, this downward tilt angle can quickly capture a full-body image of the visitor without flipping the lens. Moreover, the inward tilting design of the first inclined surface and the tilting bracket design allow the lens and infrared sensor to cover a larger area and reduce the impact of direct external light on image quality, improving recognition accuracy at night or in strong light. At the same time, the height difference between the first plane and the second plane provides sufficient space for the internal components of the doorbell body, allowing the remaining parts to be fixed inside the doorbell by the mounting bracket, simplifying the overall structure and assembly process of the doorbell.

[0007] The aforementioned video doorbell has a second inclined surface on the inclined bracket, and the infrared sensor is mounted on the second inclined surface via the second mounting bracket.

[0008] The aforementioned video doorbell also includes an angle bracket, which is installed on the wall. The rear end of the doorbell body is provided with a quick-install bracket, and the doorbell body is installed on the angle bracket via the quick-install bracket. The angle bracket has a symmetrical structure, and the doorbell body is symmetrically provided with two external power connection ports.

[0009] The aforementioned video doorbell can be directly mounted on a wall via a quick-mount bracket. The quick-mount bracket is equipped with a magnet, and the doorbell body contains a sensor switch that senses the magnet.

[0010] The aforementioned video doorbell also includes a main board in the doorbell body, with the mounting bracket mounted on the main board. A doorbell button is located on the front end of the doorbell body, below the lens. The lens, the infrared sensor, and the doorbell button are all electrically connected to the main board. A doorbell switch and a charging interface are located on the rear end of the doorbell body. An opening corresponding to the charging interface is provided on the quick-release bracket. The doorbell switch is integrally formed with the doorbell body.

[0011] The aforementioned video doorbell has multiple locking holes on its main body and multiple locking blocks on its quick-release bracket, each locking block engaging with a corresponding locking hole. The main body also includes an extendable telescopic locking block, and the quick-release bracket has locking positions that correspond to and cooperate with the telescopic locking block. The bottom of the main body has a through hole, and the telescopic locking block retracts when an external tool is inserted into the through hole.

[0012] The aforementioned video doorbell includes a telescopic locking block comprising a locking block body. A reset elastic element is provided at the end of the locking block body away from the locking position. The end of the locking block body near the locking position can extend outside the doorbell body and engage with the locking position. The bottom of the locking block body has an inclined receiving surface. A drive block located at the through hole is provided in the doorbell body. The upper end of the drive block has an inclined drive surface, which abuts against the inclined receiving surface. When the locking block body pushes the inclined receiving surface upwards on the inclined drive surface, it moves horizontally away from the locking position.

[0013] In the aforementioned video doorbell, the lower end of the tilting bracket is connected to the upper end of the mounting base, the tilting bracket is snapped onto the main board, and the mounting base is connected to the main board by screws.

[0014] In the aforementioned video doorbell, the angle between the lens and the horizontal plane is greater than 0 degrees and less than 90 degrees.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 9 This utility model provides a novel video doorbell, comprising: a doorbell body 1 and a mounting frame 4. The front end face of the doorbell body 1 has a first plane 40, a first inclined plane 2, and a second plane 50 from top to bottom. The first plane 40 is parallel to the second plane 50. The first inclined plane 2 is inclined inward from top to bottom. The height of the first plane 40 is greater than the height of the second plane 50. The two ends of the first inclined plane 2 are smoothly connected to the first plane 40 and the second plane 50. The mounting frame 4 is located inside the doorbell body 1. The mounting frame 4 includes a first mounting frame 3 and a second mounting frame 5. The first mounting frame 3 includes a vertically arranged mounting base 30 and an inclined bracket 31. The end face of the inclined bracket 31 is parallel to the first inclined plane 2. The second mounting frame 5 is fixed to the end face of the inclined bracket 31. A lens 8 can pass through the first inclined plane 2 and is fixed to the end face of the second mounting frame 5. An infrared sensor 7 is disposed on the end face of the second mounting frame 5. The visual doorbell proposed in this invention features a first inclined surface 2 located between the first plane 40 and the second plane 50, giving the front end of the entire doorbell body 1 a downward tilted viewing angle. When the lens 8 is embedded in the front end, this downward tilt angle allows for quick capture of the visitor's full-body image without flipping the lens 8. Furthermore, the inward tilt design of the first inclined surface 2 and the design of the tilt bracket 31 enable the lens 8 and infrared sensor 7 to cover a larger area and reduce the impact of direct external light on image quality, improving recognition accuracy at night or in strong light. Further, by mounting the infrared sensor 7 and lens 8 on the first inclined surface 2, the infrared sensor 7 can also be tilted to maintain alignment with the lens 8, ensuring good performance even when tilted. This gives the invention the advantages of being able to capture the entire body, easy to install, and easy to use. Simultaneously, the height difference between the first plane 40 and the second plane 50 provides sufficient space for the internal components of the doorbell body 1, allowing other parts to be fixed inside the doorbell via the mounting bracket 4, simplifying the overall structure and assembly process of the doorbell.

[0027] Embodiment 1 of this utility model is as follows: Refer to Figure 1 and Figure 2 The doorbell body 1 can be directly mounted on the wall via a quick-mount bracket 10. The quick-mount bracket 10 is equipped with a magnet 29, and the doorbell body 1 is equipped with a sensor switch that senses the magnet 29. Specifically, during installation, the quick-mount bracket 10 is mounted on the wall using screws and adhesive, and then the doorbell body 1 is mounted on the quick-mount bracket 10 to achieve quick installation of the video doorbell.

[0028] Reference Figures 2 to 3 , Figures 6 to 7 In some embodiments, the doorbell body 1 also includes a main board 12, with a mounting bracket 4 mounted on the main board 12. A doorbell button 13 is located on the front end of the doorbell body 1, below the lens 8. The lens 8, infrared sensor 7, and doorbell button 13 are all electrically connected to the main board 12. A doorbell switch 15 and a charging interface 16 are located on the rear end of the doorbell body 1. An opening 17 corresponding to the charging interface 16 is provided on the quick-release bracket 10. The doorbell switch 15 is integrally formed with the doorbell body 1. The charging interface 16 includes a Type-C interface and an AC interface, and can be connected to an external power source through these interfaces. Specifically, by integrally forming the doorbell switch 15 with the doorbell body 1, the video doorbell can save on mold costs while still achieving its on / off function.

[0029] Reference Figures 3 to 5 In some embodiments, the doorbell body 1 is provided with a plurality of locking holes 18, and the quick-release bracket 10 is provided with a plurality of locking blocks 19 in the same number as the locking holes 18, each locking block 19 engaging with the corresponding locking hole 18; the doorbell body 1 is provided with an extendable telescopic locking block 20, the quick-release bracket 10 is provided with a locking position 21 corresponding to the telescopic locking block 20, and the bottom of the doorbell body 1 is provided with a through hole 22, the telescopic locking block 20 retracting when an external tool is inserted into the through hole 22. Specifically, during installation, the quick-release bracket 10 is mounted on the wall. Multiple locking blocks 19 are engaged with multiple locking holes 18, and a telescopic locking block 20 is engaged with a locking position 21. This allows the doorbell body 1 to be quickly and securely attached to the quick-release bracket 10, ensuring that the doorbell body 1 is not easily loosened or fallen off. When disassembling the doorbell body 1, an external tool (e.g., a round rod) can be inserted from bottom to top into the through hole 22 to drive the telescopic locking block 20 to retract, thereby removing the doorbell body 1. Therefore, the telescopic locking block 20 facilitates the assembly and disassembly of the doorbell body 1. Furthermore, the through hole 22 used to drive the telescopic locking block 20 is located at the bottom of the doorbell body 1, providing good concealment without affecting the aesthetics of the video doorbell.

[0030] Reference Figure 5The telescopic block 20 includes a block body 23. A reset elastic element 25 is provided at the end of the block body 23 away from the locking position 21. The end of the block body 23 near the locking position 21 can extend out of the doorbell body 1 and cooperate with the locking position 21. The bottom of the block body 23 has an inclined receiving surface 26. A drive block 27 located at the through hole 22 is provided in the doorbell body 1. The upper end of the drive block 27 has an inclined drive surface 28. The inclined drive surface 28 abuts against the inclined receiving surface 26. When the inclined drive surface 28 pushes the inclined receiving surface 26 upward, the block body 23 moves horizontally away from the locking position 21. Specifically, when disassembling the doorbell body 1, an external tool (such as a round bar) can be inserted into the through hole 22 from bottom to top to push the drive block 27 upward. Due to the push of the inclined drive surface 28 on the inclined driven surface 26, the locking block body 23 moves horizontally away from the locking position 21 to compress the reset elastic member 25. At this time, the locking block body 23 retracts to disengage from the locking position 21, thereby allowing the doorbell body 1 to be removed. When the external tool is removed, the locking block body 23 is reset under the elastic force of the reset elastic member 25, and the locking block body 23 extends again.

[0031] Reference Figures 3 to 4 The quick-release bracket 10 is equipped with a magnet 29, and the doorbell body 1 has a sensor switch that senses the magnet 29. The sensor switch is a Hall effect sensor switch. A groove is formed on the doorbell body 1, into which the magnet 29 on the quick-release bracket 10 can be fitted; this groove is directly opposite the sensor switch. Specifically, during normal assembly, the quick-release bracket 10 is connected to the doorbell body 1, and the sensor switch is in the off state. When the doorbell body 1 is disassembled, the sensor switch is triggered, and the video doorbell will sound an alarm. Therefore, this invention can trigger an alarm when the doorbell body 1 is forcibly removed, thus providing good security.

[0032] Reference Figure 6 The first mounting bracket 3 includes a vertically arranged mounting base 30 and an inclined bracket 31. The lower end of the inclined bracket 31 is connected to the upper end of the mounting base 30. A second inclined surface 6 is formed on the inclined bracket 31. The inclined bracket 31 is snapped onto the motherboard 12, and the mounting base 30 is connected to the motherboard 12 by screws. Specifically, both ends of the inclined bracket 31 are provided with buckles, which are snapped onto both ends of the motherboard 12. At the same time, the mounting base 30 is connected to the motherboard 12 by screws to achieve a stable installation of the first mounting bracket 3, so as to ensure that the lens 8 installed on the first mounting bracket 3 is stable and not easily displaced. Of course, this utility model does not limit the specific angle between the lens and the infrared sensor and the horizontal plane. Preferably, the angle between the lens 8 and the horizontal plane is greater than 0 degrees and less than 90 degrees; the angle between the infrared sensor 7 and the horizontal plane is greater than 0 degrees and less than 90 degrees. At this angle, the lens has a better viewing angle and viewing range.

[0033] The second embodiment of this utility model is as follows: The difference between the second embodiment and the first embodiment is that the second embodiment further includes an inclined bracket 9 installed on the wall, and the quick-install bracket 10 is not installed on the wall, but on the inclined bracket 9. Specifically, refer to... Figures 8 to 9 As shown, in this embodiment, the doorbell also includes an angle bracket 9, which is installed on the wall. A quick-install bracket 10 is provided on the rear end face of the doorbell body 1. The doorbell body 1 is installed on the angle bracket 9 via the quick-install bracket 10. The angle bracket 9 has a symmetrical structure, and two external power connection ports 11 are symmetrically arranged on the doorbell body 1. Specifically, the angle bracket 9 is a bracket tilted 15 degrees to the side. Because the angle bracket 9 has a symmetrical structure, it can be compatible with both left and right orientations, allowing it to be installed on the wall on one side of the entrance door or on the wall on the other side of the entrance door. Furthermore, the two symmetrically arranged external power connection ports 11 are compatible with the symmetrical structure of the angle bracket 9, ensuring that the angle bracket 9 can be connected via the corresponding external power connection port 11 whether installed to the left or right, without affecting the external power connection.

[0034] It should be noted that some entrance doors (such as stainless steel doors) are not suitable for installing video doorbells, or installing a video doorbell on the entrance door with 3M tape may result in insufficient security. Installing a video doorbell on a wall provides better security and is easy to install. However, when the video doorbell is installed on a wall located on one side or the other side of the entrance door, it is not directly facing the front of the entrance door. When a visitor stands directly in front of the entrance door, the shooting angle is not ideal. Therefore, this utility model can achieve wall-mounted installation of the video doorbell using an angle bracket 9, so that the lens 8 can be aimed at the visitor directly in front of the entrance door. This not only provides a better shooting angle for visitors standing directly in front of the entrance door, but also allows for installation on either a wall on one side or the other side of the entrance door, depending on the actual location of the entrance door.

[0035] It should be noted that in the description of this utility model, any descriptions of orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of this utility model.
