Description

Technical Field

[0001] This application relates to the field of home security, and more particularly to an electronic device. Background Technology

[0002] With the advancement of society and technology, in order to enhance security and reliability, cameras are often installed in electronic devices such as doorbells used in the field of home security. This allows the electronic devices to serve both a visual and surveillance function. Through cameras and other devices, users can know what is happening at their doorstep when they are not at home, so as to provide strong evidence in case of an accident.

[0003] However, in related technologies, when a camera is installed on an electronic device, the connection between the camera and the device's casing is not secure enough, making the camera prone to detachment. Utility Model Content

[0004] This application provides an electronic device that makes the mounting of the lens on the main body more secure and convenient.

[0005] Specifically, an electronic device is characterized by comprising: The main body has a receiving cavity; A camera, mounted on the main body, includes a lens and a first circuit board. One end of the lens with a light-emitting surface is located within the receiving cavity, and the other end of the lens with a light-incident surface protrudes from the main body. The first circuit board is located within the receiving cavity and connected to the lens. A mounting bracket is located within the receiving cavity. The mounting bracket includes a support portion and a mounting portion connected to the support portion. The support portion is disposed on the outer periphery of the lens and located between the lens and the first circuit board. The lens and / or the first circuit board is connected to the support portion. The mounting portion is located on the side of the support portion away from the lens and is connected to the main body, so that the camera is mounted on the main body via the mounting bracket.

[0006] The beneficial effects of this application are as follows: On the one hand, the first circuit board and / or lens are mounted on the main body via a mounting bracket, thereby enabling the connection between the lens and the main body, and thus enabling the camera to be mounted on the main body. On the other hand, the mounting bracket, as a transfer structure between the camera and the main body, allows the size of the mounting bracket to be flexibly adjusted according to the size of the lens during assembly, without being limited by the size of the camera relative to the main body. This allows the mounting bracket to be directly connected to the inner circumference of the main body, facilitating the installation of the camera. Furthermore, the support portion connects the lens and the first circuit board to the camera, and the position of the mounting portion can be adjusted according to the position of the lens within the receiving cavity. This makes the connection between the mounting portion and the main body more convenient and secure, thereby ensuring the installation strength of the camera, preventing the camera from becoming loose, and filling the gap between the first circuit board and the lens. The support portion provides support for the lens along the optical axis, preventing the lens from sinking when pressed. Attached Figure Description

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] In related technologies, on the one hand, when a camera is installed on an electronic device, the connection between the camera and the device's casing is not secure enough, making the camera prone to detachment. On the other hand, camera lenses are typically large, meaning their size may be close to or larger than the electronic device's casing. This results in a small space between the portion of the lens inside the casing and the inner wall of the casing, making it difficult to mount the lens onto the casing.

[0012] In view of the above-mentioned technical problems, this application provides an electronic device to solve the above problems.

[0013] Specifically, such as Figure 1 and Figure 2 As shown, the electronic device includes a main body 10 and a camera 21. The electronic device can be powered by a battery 12 or / and by a power source such as the mains grid. When the electronic device is powered by the battery 12, the main body 10 may include a battery compartment 11 for installing the battery 12, which powers the electronic components in the electronic device. When the electronic device is powered by the mains grid, the main body 10 may include a power interface for connecting to the mains grid, which powers the electronic components in the electronic device. The following description uses a doorbell as an example; however, in specific implementations, the electronic device can also be other devices with a camera 21, such as a door lock or a security monitor.

[0014] The main body 10 is provided with a receiving cavity 15; the camera 21 is installed on the main body 10 and is used to acquire image information of the target area. The camera 21 includes a lens 211 and a first circuit board 213. One end of the lens 211 with a light-emitting surface 211b is located in the receiving cavity 15, and the other end of the lens 211 with a light-incident surface 211a protrudes from the main body 10. The first circuit board 213 is located in the receiving cavity 15 and is connected to the lens 211.

[0015] Understandably, the end of lens 211 with light-emitting surface 211b is located within the receiving cavity 15, which can fully utilize the space within the main body 10, thereby reducing the overall size of the doorbell. Furthermore, the end of lens 211 with light-incident surface 211a protrudes from the main body 10 to prevent the field of view of lens 211 from being blocked by the main body 10. Specifically, when the doorbell is installed on a door or wall, the end of lens 211 with light-emitting surface 211b faces outwards, and the end of lens 211 with light-incident surface 211a faces outwards. Generally, the target area refers to the area near the doorbell, such as the area near the front door. The range of the target area can be selected according to the actual situation. Generally, the area that camera 21 can capture includes the target area.

[0016] It should also be noted that the image information acquired by the camera 21 may include image information and video information. The first circuit board 213 is located on the side of the lens 211 with the light-emitting surface 211b. The camera 21 may also include an image sensor 212 disposed on the side of the lens 211 with the light-emitting surface 211b. The image sensor 212 is mounted on the first circuit board 213 and electrically connected to the first circuit board 213. The image sensor 212 is used to receive light transmitted through the lens 211. When light reflected from a target object (which may be a person or an object) in the target area enters the lens 211 from the light-incident surface 211a, passes through the lens 211, and exits from the light-emitting surface 211b of the lens 211, the light transmitted through the lens 211 is received by the image sensor 212. The image sensor 212 generates an electrical signal that is proportional to the image. The first circuit board 213 can supply power to the image sensor 212 and analyze the electrical signal generated by the image sensor 212 based on the image captured by the camera 21 to obtain image information. This allows the camera to capture events occurring in the target area, providing strong evidence in case of an accident. The specific working principle of the image sensor 212 has been disclosed in related technologies and will not be elaborated here. The specific specifications and shape of the image sensor 212 can be selected according to the actual situation and are not limited here.

[0017] Specifically, the electronic device also includes a mounting bracket 22 located within the receiving cavity 15. The mounting bracket 22 includes a support portion 221 and a mounting portion 222 connected to the support portion 221. The support portion 221 is disposed on the outer periphery of the lens 211 and located between the lens 211 and the first circuit board 213. The lens 211 and / or the first circuit board 213 are connected to the support portion 211. The mounting portion 212 is located on the side of the support portion 211 away from the lens 211 and is connected to the main body 10, so that the camera 21 is mounted on the main body 10 via the mounting bracket 22. Alternatively, only the lens 211 may be connected to the support portion 211, in which case the first circuit board 213 is connected to the support portion 211 via the lens 211; alternatively, only the first circuit board 213 may be connected to the support portion 211, in which case the lens 211 may be connected to the support portion 211 via the first circuit board 213; or both the lens 211 and the first circuit board 213 may be connected to the support portion 211.

[0018] Understandably, the lens 211 of the camera 21 is typically large, meaning its size may be close to or larger than the size of the main body 10. Specifically, for example, the projection edge contour of the lens 211 onto the main body 10 may coincide with or be close to the edge contour of the main body 10. Since the end of the lens 211 with its light-emitting surface 211b is installed inside the main body 10, sufficient space needs to be provided within the main body 10 to accommodate the lens 211. This results in a smaller space between the end of the lens 211 with its light-emitting surface 211b and the inner wall of the main body 10. Consequently, it is difficult to provide a mounting structure (such as screw posts) for the lens 211 on the outer periphery of the portion of the lens 211 located inside the main body 10. This makes it difficult to directly mount the lens 211 onto the main body 10, and even if the lens 211 is directly connected to the main body 10, it is prone to loosening due to insufficiently secure connection.

[0019] In this embodiment, on the one hand, the first circuit board 213 and / or the lens 211 are mounted on the main body 10 via the mounting bracket 22, thereby enabling the lens 211 to be connected to the main body 10 and thus allowing the camera 21 to be mounted on the main body 10. On the other hand, the mounting bracket 22 serves as a transfer structure between the camera 21 and the main body 10, allowing its size to be flexibly adjusted according to the size of the lens 211 during assembly, without being limited by the size of the camera 21 relative to the main body 10. This allows the mounting bracket 22 to be directly connected to the inner periphery of the main body 10, facilitating the installation of the camera 21. Furthermore, the support portion 221 connects the lens 211 to the first circuit board 213, and the position of the mounting portion 222 can be adjusted according to the position of the lens 211 within the receiving cavity 15. This makes the connection between the mounting portion 222 and the main body 10 more convenient and secure, thereby ensuring the installation strength of the camera and preventing it from becoming loose.

[0020] It should also be noted that the support portion 221 can fill the gap between the first circuit board 213 and the lens 211, and can provide support for the lens 211 along the optical axis extension direction of the lens 211, preventing the lens 211 from sinking when pressed. The optical axis extension direction of the lens 211 is parallel to the thickness direction ZZ of the main body 10.

[0021] like Figures 2 to 6As shown, in some embodiments, the support portion 221 is provided with a through hole 221c, through which the lens 211 passes. It can be understood that the through hole 221c can be used to limit and fix the lens 211, preventing the lens 211 from shaking. Furthermore, the support portion 221 can support and limit the periphery of the lens 211, making the camera 21 more securely installed and preventing the lens 211 from sinking when pressed.

[0022] In some embodiments, the support portion 221 includes a first frame 221a and a second frame 221b. The first frame 221a is connected to at least one of the lens 211 and the first circuit board 213. The second frame 221b is connected to at least one of the first frame 221a, the first circuit board 213 and the lens 211. The second frame 221b and the first frame 221a enclose a through hole 221c, through which the lens 211 passes.

[0023] The mounting part 222 is connected to at least one of the first frame 221a and the second frame 221b. It is understood that, to install the mounting bracket 22 onto the main body 10, the first frame 221a can be moved towards the lens 211 along one radial side, and then the second frame 221b can be moved towards the lens 211 along the other radial side, so that the second frame 221b and the first frame 221a enclose a through hole 221c. The first frame 221a and the second frame 221b are fixed together by the first mounting member 223. At this time, the lens 211 passes through the through hole 221c, which can limit and fix the lens 211. Then, the first frame 221a and / or the second frame 221b are fixed to the first circuit board 213 by the second mounting member 224. Then, the mounting part 222 is connected and fixed to the main body 10 by the third mounting member 225, thereby realizing the installation of the camera 21. The first mounting member 223, the second mounting member 224, and the third mounting member 225 can be screws or other connecting parts. Of course, in other embodiments, the first frame 221a and the second frame 221b may not be fixed together by the first mounting member 223, but only the first frame 221a, the second frame 221b, and the first circuit board 213 are fixed by the second mounting member 224.

[0024] In some embodiments, both the first frame 221a and the second frame 221b extend along the outer periphery of the lens 211, and at least partially overlap in the optical axis extension direction of the lens 211. It is understood that, on the one hand, the support portion 221 has stronger structural strength at the overlap of the first frame 221a and the second frame 221b, resulting in greater stability and support strength for the support portion 221 as a whole, and reducing the overall volume of the support portion 221, thereby reducing the space occupied by the support portion 221 and making installation of the support portion 221 within the receiving cavity 15 more convenient; on the other hand, the overlapping portion of the first frame 221a and the second frame 221b makes the connection and fixation of the first frame 221a and the second frame 221b more convenient. For example, the first mounting member 223 can pass through the overlapping portion of the first frame 221a and the second frame 221b to achieve the connection between the first frame 221a and the second frame 221b.

[0025] In some embodiments, the first frame 221a includes a first connecting portion 221a2 and a first overlapping portion 221a1 connected to the first connecting portion 221a2, the first connecting portion 221a2 and the first overlapping portion 221a1 being located at both ends of the first frame 221a, and the second frame 221b includes a second connecting portion 221b2 and a second overlapping portion 221b1 connected to the second connecting portion 221b2, the second connecting portion 221b2 and the second overlapping portion 221b1 being located at both ends of the second frame 221b.

[0026] In the optical axis extension direction of lens 211, the first overlapping portion 221a1 and the second overlapping portion 221b1 at least partially overlap and are connected; in the radial direction of lens 211, the first connecting portion 221a2 and the second connecting portion 221b2 at least partially overlap and are connected; the radial direction of lens 211 is perpendicular to the optical axis extension direction of lens 211; the radial direction of lens 211 can be parallel to the length direction YY or the width direction XX of the main body 10; the radial direction of lens 211 can also intersect the length direction YY and the width direction XX of the main body 10.

[0027] Understandably, the first frame 221a and the second frame 221b can be connected in the optical axis extension direction of the lens 211 by the second mounting member 224 passing through the first overlapping portion 221a1 and the second overlapping portion 221b1, and the lens 211 can be connected radially by the fourth mounting member 226 passing through the first connecting portion 221a2 and the second connecting portion 221b2. This multi-directional connection between the first frame 221a and the second frame 221b makes the connection more secure. The fourth mounting member 226 can be a screw or other connecting component.

[0028] like Figure 7 As shown, in some embodiments, a positioning part 16 is connected to the inner wall of the receiving cavity 15. The positioning part 16 and the mounting part 222 are arranged along the optical axis of the lens 211. The mounting part 222 is connected to the positioning part 16 so that the camera 21 is mounted on the main body 10 via the mounting bracket 22. The connection between the mounting bracket 22 and the main body 10 can be achieved by a third mounting member 225 passing through the positioning part 16 and the mounting part 222. The mounting part 222 may be provided on only one of the first frame 221a and the second frame 221b, or it may be provided on both the first frame 221a and the second frame 221b. The number of mounting parts 222 may be one, two, or more.

[0029] In some embodiments, the third mounting member 225 can penetrate the mounting portion 222 and be connected to the mounting portion 222. The positioning portion 16 is provided with an assembly hole 14 for the third mounting member 225 to be inserted. There is a gap between the third mounting member 225 and the inner wall of the assembly hole 14, so that the main body 10 can allow the mounting bracket 22 to move along the width direction XX and the length direction YY of the main body 10, and prevent the mounting bracket 22 from moving along the thickness direction ZZ of the main body 10.

[0030] It is understandable that the mounting bracket 22 can move in the width direction XX and the length direction YY of the main body 10, so that when assembling the sealing structure 24 and the lens 211, the lens 211 can adaptively adjust its position under the force applied by the sealing structure 24. This can prevent the lens 211 from being subjected to a large local force at the waterproof rib of the sealing structure 24 due to assembly tolerance issues, thereby preventing the problem of blurry images captured by the camera 21 due to excessive local stress.

[0031] In some embodiments, the first frame 221a and the second frame 221b are detachably connected to facilitate subsequent inspection and replacement of the lens 211. The first frame 221a can be detachably connected by snap-fit, threaded connection, magnetic connection or other means.

[0032] See also Figure 2As shown, in some embodiments, the lens 211 may include a lens barrel 211c and a lens 211d group. The lens barrel 211c extends around the outer periphery of the lens 211d group. The lens 211d group may include a plurality of lenses 211d arranged along the optical axis extension direction of the lens 211. The optical axis extension direction is parallel to the thickness direction ZZ of the body 10. The lenses 211d may be of the type of planar lens 211d, concave lens 211d, or convex lens 211d. By designing the number of lenses 211d and the type of each lens 211d, a lens 211 that meets the field of view requirements can be obtained.

[0033] In some embodiments, the lens 211 may further include a base 211e, which is located between the first circuit board 213 and the lens barrel 211c, and is connected to the first circuit board 213 and the lens barrel 211c. The base 211e may extend around the outer periphery of the image sensor 212 to avoid the image sensor 212.

[0034] It should also be noted that when installing the camera 21, the lens barrel 211c can be fixed to the base 211e by dispensing adhesive first, and then the base 211e can be fixed to the first circuit board 213 by dispensing adhesive. Then the first circuit board 213 can be fixed to the mounting bracket 22 by screws or other devices. Then the mounting bracket 22 can be fixed to the main body 10 by screws or other devices. The dispensing adhesive of the base 211e can be connected to the first circuit board 213 by AA (Active Alignment) process to ensure the optical performance of the camera 21.

[0035] like Figure 8 As shown, in some embodiments, the horizontal field of view V1 and the vertical field of view V2 of lens 211 are both greater than or equal to 180 degrees, and a large field of view can be achieved using a single lens 211. Specifically, the horizontal field of view V1 of lens 211 can be 180 degrees, 190 degrees, 200 degrees, or other degrees, and the vertical field of view V2 of lens 211 can be 180 degrees, 190 degrees, 200 degrees, or other degrees. The horizontal field of view V1 and the vertical field of view V2 of lens 211 can be equal or unequal.

[0036] Understandably, the field of view (FOV) of lens 211 refers to the angle formed by the two edges of the maximum range of the target image that can be seen through lens 211, with the center line N of lens 211 as the vertex. The FOV describes the shooting range of camera 21. Generally, camera 21 can photograph targets within the FOV range of lens 211, but cannot photograph targets outside the FOV range. The horizontal field of view V1 of lens 211 refers to the field of view of lens 211 in the horizontal direction, describing the maximum range that lens 211 can observe in the horizontal direction. The vertical field of view V2 of lens 211 refers to the field of view of lens 211 in the vertical direction, describing the maximum range that lens 211 can observe in the vertical direction.

[0037] It should be noted that in this application, by setting a lens 211 with a large horizontal field of view V1 and a vertical field of view V2 (both greater than or equal to 180 degrees), the camera 21 can have a large shooting range. This prevents situations where someone approaches the doorbell but the camera 21 fails to detect them, and the doorbell has a stronger anti-theft function. Users can use the camera 21 to better check if anyone is stealing, thereby further improving the doorbell's reliability. Furthermore, because the camera 21 has a horizontal field of view greater than or equal to 180 degrees, the areas on the left and right sides of the doorbell near the wall are also within the camera 21's shooting range, thus solving the problem that the camera 21 has difficulty detecting and shooting areas near the wall, such as the left and right sides of the doorbell.

[0038] It is also worth mentioning that the camera 21 has a field of view of 180 degrees or more in the vertical direction, which allows the camera 21 to perform comprehensive detection of the area near the door. This enables users to better realize more functions through the doorbell, such as when a package is delivered to the door and is located below the doorbell, the package is also within the shooting range of the camera 21. When the camera 21 captures the package, it can notify the user to receive the package through wireless communication or other means.

[0039] In some embodiments, lens 211 is a fisheye lens. It should be noted that a fisheye lens is an ultra-wide-angle lens 211, characterized by a large field of view, allowing both the horizontal field of view V1 and the vertical field of view V2 of lens 211 to be greater than or equal to 180 degrees. The principle behind the large field of view of a fisheye lens is that: when the human eye rotates to observe, the field of view can expand to degrees, while when the eye is stationary, the effective field of view is only degrees. Unlike the human eye, the lens in a fish's eye is spherical, thus, although it can only see relatively close objects, it has a larger viewing angle and therefore sees a wider field of view. The front lens of the fisheye lens (lens 211d closest to the light-incident side of the fisheye lens) has a very short diameter. The front lens 211d has a light-incident surface 211a, which protrudes parabolically toward the light-outcident side of the fisheye lens, much like a fish's eye, thereby enabling the fisheye lens to have a large field of view. The specific working principle of fisheye lenses has been disclosed in relevant technologies and will not be elaborated upon here.

[0040] In other embodiments, the lens 211 may not be a fisheye lens. The horizontal field of view V1 and the vertical field of view V2 of the formed lens 211 can be designed to meet the requirements (greater than or equal to 180 degrees) by designing the number of lenses 211d and the curvature of each lens 211d.

[0041] like Figures 1 to 3 As shown, in some embodiments of this application, the camera 21 further includes a protective member 23. The protective member 23 is disposed at one end of the lens 211 having a light-incident surface 211a. The protective member 23 is connected to the lens 211 and / or the main body 10. The protective member 23 can limit and fix the lens 211 at the end having a light-incident surface 211a to prevent the camera 21 from coming out of the main body 10.

[0042] The protective member 23 protrudes away from the main body 10 from the outer edge of the light-incident surface 211a. Thus, the protective member 23 can provide edge protection for the lens 211, so that the part of the light-incident surface 211a near the edge can be hidden in the area formed by the protective member 23. Stray light and other interfering light transmitted to the edge of the light-incident surface 211a can be blocked by the protective member 23, preventing interfering light from affecting the imaging of the camera 21.

[0043] like Figure 2 and Figure 9As shown, in some embodiments, the doorbell also includes an infrared lamp 41. The infrared lamp 41 is installed on the side of the main body 10 near the camera 21 and located to the side of the lens 211. The infrared lamp 41 is used to cooperate with the camera 21 so that the camera 21 can work in infrared night vision mode. It should be noted that the camera 21 has an infrared night vision mode. At night or other times when the light is weak, the infrared lamp 41 can be turned on to provide infrared illumination for the camera 21, and the camera 21 enters infrared night vision mode. The infrared light emitted by the infrared lamp 41 is reflected by the target object and enters the lens 211 through the light-receiving surface 211a of the lens 211, and is received by the image sensor 212, so that the camera 21 can take clear pictures at night.

[0044] Among them, such as Figure 2 As shown, the light-incident surface 211a is a convex surface, the protective member 23 extends along the outer periphery of the lens 211, and the central vertex of the light-incident surface 211a protrudes away from the main body 10 relative to the protective member 23. It can be understood that the central vertex is the intersection of the centerline N of the lens 211 and the light-incident surface 211a. Figure 2 In practice, the top of the protective element 23 is higher than the outer edge of the light-incident surface 211a, so that the part of the light-incident surface 211a near the edge can be hidden in the area enclosed by the protective element 23. Part of the light emitted by the infrared lamp 41 in the direction of the lens 211 can be blocked by the protective element 23, thereby preventing infrared cross-beaming after the infrared light enters the lens 211. At the same time, the central vertex of the light-incident surface 211a is higher than the protective element 23. Since the field of view is the angle formed by the center line N of the light-incident surface 211a as the vertex, and the central vertex is usually higher than the vertex of the field of view of the lens 211, the visible field of view V3 formed by the central vertex as the vertex of the field of view is smaller than the field of view of the lens 211. Since the central vertex is higher than the protective element 23, even if part of the edge field of view of the visible field of view V3 is blocked by the protective element 23, the visible field of view V3 can still be greater than or equal to 180 degrees, thereby ensuring that the field of view of the lens 211 can also be greater than or equal to 180 degrees.

[0045] It should also be noted that there can be one, two or more infrared lamps 41, and the infrared lamps 41 can be set on any side of the lens 211, such as the lower side, upper side, left side and right side. When there are multiple infrared lamps 41, the multiple infrared lamps 41 can be arranged at intervals along the length YY or width XX of the main body 10, or the multiple infrared lamps 41 can be arranged at intervals along the circumference of the lens 211.

[0046] It should also be noted that the protective component 23 can extend around the outer periphery of the lens 211, or it can extend around the outer periphery of the lens 211 by half a circle, a small half circle, or a large half circle, and the protective component 23 is located on the side of the lens 211 closer to the infrared lamp 41.

[0047] In some embodiments, the electronic device further includes a communication antenna 42, which is disposed on the main body 10 and located on the side of the protective member 23 closer to the main body 10 (hereinafter, the rear side of the protective member 23 will be described). The protective member 23 is a metal part, which allows the protective member 23 to reflect the electromagnetic waves radiated by the communication antenna 42 to the rear side of the protective member 23. It is understood that when the doorbell is installed on a door or wall, the rear side of the protective member 23 is the side facing the interior. The communication antenna 42 is used to realize wireless communication connection between the doorbell and electronic devices such as mobile phones and computers. The doorbell can transmit information to other electronic devices through the electromagnetic waves radiated by the antenna, such as receiving and transmitting image information from the camera 21, alarm information, etc.

[0048] It is understandable that metallic materials have a strong ability to reflect electromagnetic waves. Since the protective component 23 is a metallic component, it has good electromagnetic wave reflection performance. The protective component 23 can act as a reflector for the communication antenna 42. Electromagnetic waves radiated from the communication antenna 42 onto the protective component 23 can be reflected by the protective component 23 to the rear side and into the room, thereby enhancing the directional radiation performance of the communication antenna 42 in the direction towards the room, and thus improving the communication effect between the communication antenna 42 and electronic devices located indoors. The protective component 23 can be made of copper, aluminum, iron, copper alloy, aluminum alloy, iron alloy, or other metallic materials.

[0049] In some embodiments, the thickness of the protective member 23 can be twice the wavelength of the electromagnetic wave radiated by the communication antenna 42, which can enhance the reflection performance of the protective member 23 on the electromagnetic wave radiated by the communication antenna 42; of course, the thickness of the protective member 23 can be other multiples of the wavelength of the electromagnetic wave radiated by the communication antenna 42.

[0050] In some embodiments, the protective component 23 can be fixed to the main body 10 by means of clips or adhesive, so that the connection between the protective component 23 and the main body 10 is more reliable, thereby providing a better limiting effect on the lens 211.

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the camera 21 further includes a sealing structure 24 located between the protective member 23 and the lens 211. The sealing structure 24 includes a sealing ring 241 and a reinforcing member 242. The sealing ring 241 extends around the outer periphery of the lens 211 and abuts against the protective member 23 and the lens 211. The reinforcing member 242 is disposed on the sealing ring 241, and the structural strength of the reinforcing member 242 is greater than the structural strength of the sealing ring 241. It is understood that the sealing structure 24 can achieve a seal between the protective member 23 and the sealing ring 241, preventing moisture or dirt from entering the body 10 through the gap between the protective member 23 and the sealing ring 241.

[0052] It should also be noted that, in this application, the lens 211 has a large volume. If only a rubber seal is used to seal the outer periphery of the lens 211, the rubber seal needs to have a large volume, which will result in insufficient overall structural strength of the rubber seal. During the assembly of the rubber seal with the lens 211, the rubber seal is prone to large deformation, which makes the waterproof rib of the rubber seal (the part of the inner side of the rubber seal that contacts the lens 211) easily overturned by the lens 211, resulting in seal failure.

[0053] In this application, the sealing ring 241 abuts against the protective component 23 and the lens 211 to achieve a seal between the protective component 23 and the lens 211. The structural strength of the sealing ring 241 is relatively small, making it easier to deform. This allows the sealing ring 241 to make closer contact with the protective component 23 and the lens 211, thus ensuring a sealing effect. At the same time, by setting a reinforcing component 242 on the sealing ring 241 to enhance the overall structural strength of the sealing structure 24, it is possible to prevent the sealing structure 24 from undergoing large deformation during assembly. This prevents the waterproof ribs of the sealing structure 24 from being overturned by the lens 211, which could lead to sealing failure.

[0054] Furthermore, since the sealing structure 24 has sufficient structural strength, when assembling the sealing structure 24 and the lens 211, the lens 211 can be installed first, and then the sealing structure 24 can be installed. This can prevent the lens 211 from being subjected to large local forces at the waterproof ribs of the sealing structure 24 due to assembly tolerance issues. This can prevent the problem of blurry images captured by the camera 21 due to excessive local stress. This is because, in order to improve assembly accuracy, the camera 21 is usually assembled using the AA process, which makes the lens 211 of the camera 21 more sensitive to external forces. Uneven force can easily cause uneven clarity.

[0055] In some embodiments, the sealing ring 241 may be a rubber sealing ring 241 such as a silicone sealing ring 241; of course, the sealing ring 241 may also be formed of other materials. The reinforcing member 242 may be formed of steel, copper alloy, or other metallic materials.

[0056] In some embodiments, a reinforcing groove 241a may be formed on the side of the sealing ring 241 away from the lens 211 (i.e., the outer side of the sealing ring 241), and a reinforcing member 242 may be disposed within the reinforcing groove 241a. The reinforcing member 242 may extend continuously around the circumference of the sealing ring 241, and the reinforcing member 242 may also include a plurality of reinforcing blocks spaced apart around the circumference of the sealing ring 241.

[0057] In some embodiments, the sealing ring 241 and the reinforcing member 242 can be connected by connecting reinforcing members 243 such as screws, and the sealing structure 24 can be connected and fixed to the main body 10 by connecting reinforcing members 243, thereby making the connection between the sealing ring 241 and the reinforcing member 242 tighter and preventing the sealing structure 24 from loosening. Multiple connecting reinforcing members 243 can be evenly distributed along the circumference of the sealing ring 241 to make the sealing structure 24 subject to more uniform force.

[0058] like Figure 9 As shown, in some embodiments, the camera 21 has a sleep state and an operating state. When the camera 21 is in the sleep state, it is in standby mode and does not capture images of the target area. At this time, the camera 21 consumes less power. When the camera 21 is in the operating state, it is in normal operation mode and captures images of the target area to obtain image information near the doorbell. This allows the camera to detect events happening near the doorbell and know what is happening at the door, providing strong evidence in case of an accident. At this time, the camera 21 consumes more power.

[0059] The doorbell may also include a trigger component 30, which is installed on the main body 10 and is communicatively connected to the camera 21. The trigger component 30 is used to switch the camera 21 from a sleep state to a working state when it is triggered by a target object in the target area.

[0060] It should be noted that the triggering component 30 can detect target objects in the target area and be triggered by the target objects. The power consumption of the triggering component 30 is lower than that of the camera 21. When the target object moves to the target area, the triggering component 30 is triggered and sends a trigger signal to the camera 21, causing the camera 21 to switch from the sleep state to the working state. The triggering component 30 can send a trigger signal directly to the camera 21, or it can send a trigger signal to the camera 21 through the control component in the main body 10.

[0061] It is understandable that by setting a trigger component 30 with relatively low power consumption to control the state switching of the camera 21, the camera 21 will only enter the working state and take pictures of the target object when the trigger component 30 is triggered due to the presence of a target object in the target area. When there is no target object in the target area, or when the target object has left the target area for a period of time, the camera 21 does not need to work and can enter the sleep state, thereby reducing the power consumption of the camera 21. Furthermore, when the doorbell is powered by the battery 12, the power consumption of the battery 12 can be reduced, thereby extending the battery 12's usage time and eliminating the need for users to frequently replace the battery 12.

[0062] like Figure 9 and Figure 10 As shown, the trigger assembly 30 includes multiple trigger elements 31, and the sum of the overall horizontal trigger angles of the multiple trigger elements 31 is greater than or equal to 180 degrees, so that the horizontal trigger angle of the trigger assembly 30 is greater than or equal to 180 degrees. It should be noted that, taking the horizontal trigger angle of each trigger element 31 as the first horizontal trigger angle α and the horizontal trigger angle of the trigger assembly 30 as the overall horizontal trigger angle β as an example, the first horizontal trigger angle α is the angle formed by the two edges of the horizontal trigger range of the trigger element 31 in the horizontal direction, and the overall horizontal trigger angle β is the angle formed by the two edges of the overall horizontal trigger range of the trigger assembly 30 in the horizontal direction.

[0063] It is understood that in this application, the trigger component 30 includes multiple trigger elements 31. The multiple trigger elements 31 cooperate with each other, and the horizontal trigger angles of the multiple trigger elements 31 together form the horizontal trigger angle of the trigger component 30, so that the trigger component 30 can have a large horizontal trigger angle (greater than or equal to 180 degrees). The horizontal trigger ranges of the multiple trigger elements 31 together form the horizontal trigger range of the trigger component 30, so that the trigger component 30 can have a large horizontal trigger range. This allows the area near the doorbell to be within the horizontal trigger range of the trigger component 30, and the areas on the left and right sides of the doorbell close to the wall are also within the horizontal trigger range of the trigger component 30. This allows the trigger elements 31 to detect when a target object moves from the left or right sides of the doorbell towards the target area, thereby triggering the trigger elements 31. This reduces the probability of missed triggers and can solve some usage scenarios that trouble users, such as when the monitoring image of the camera 21 only shows a person suddenly appearing in the target area of ​​the doorbell, without showing the process of a person walking towards the doorbell from a distance, thus further improving the reliability of the doorbell.

[0064] In some embodiments, the plurality of triggers 31 include at least one of a PIR trigger 31 and a radar trigger 31. It is understood that a PIR (Pssive Infrared Sensor), also known as a pyroelectric infrared sensor, has advantages such as low power consumption and low cost. It relies on passively absorbing the infrared radiation emitted by an animal's body during activity to trigger an alarm. When a target object moves in the target area, the change in the target object's thermal energy will trigger the PIR trigger 31. The specific working principle of PIR has been disclosed in related technologies and will not be elaborated upon here. Radar is an electronic device that uses electromagnetic waves to detect targets. Radar illuminates the target by emitting electromagnetic waves and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance, azimuth, and altitude. The radar trigger 31 can detect the target object in the target area and is thus triggered by the target object. The specific working principle of radar has been disclosed in related technologies and will not be elaborated upon here.

[0065] In some embodiments, the main body 10 further includes a second circuit board 13, on which at least one trigger 31 may be disposed, thereby shortening the connection trace between the trigger 31 and the second circuit board 13. The second circuit board 13 may be communicatively connected to the first circuit board 213, enabling the trigger 31 to communicate with the camera 21.

[0066] See also Figure 9 As shown, in some embodiments, the doorbell also includes a light-transmitting cover 51, which covers the front side of the main body 10. Part of the trigger 31 may be located between the light-transmitting cover 51 and the main body 10. It should be noted that the front side of the main body 10 refers to the side of the main body 10 facing the target area. When the doorbell is installed on a door or wall, the front side of the main body 10 is the side facing outdoors. The light-transmitting cover 51 can be formed of light-transmitting plastic or other light-transmitting materials. The light-transmitting cover 51 can provide protection for the trigger 31, preventing dust and other dirt from accumulating on the trigger 31.

[0067] In some embodiments, the main body 10 is provided with a supplementary light 43. Users can set the turn-on time of the supplementary light 43 so that the supplementary light 43 can be turned on at night so that the target object approaching the doorbell can be seen more clearly at night.

[0068] The supplementary light 43 can be positioned at the top of the main body 10 (e.g., Figure 11 ) or / and bottom (e.g. Figure 1 The supplementary light 43 can also be set on the left and right sides of the main body 10.

[0069] See also Figure 9 As shown, in some embodiments, a photosensitive element 44 is provided on the main body 10. The photosensitive element 44 can be communicatively connected to the supplementary light 43. The photosensitive element 44 is a sensor that can convert light signals into electrical signals. It can sense changes in the brightness of the target area, causing the supplementary light 43 to turn on and off according to the light intensity of the target area. When the light in the target area dims and the light intensity is lower than a first preset value, the photosensitive element 44 sends an on signal to the supplementary light 43, so that the supplementary light 43 can automatically turn on to illuminate the area near the doorbell. When the light in the target area brightens and the light intensity is higher than a second preset value, the photosensitive element 44 sends an off signal to the supplementary light 43, so that the supplementary light 43 can automatically turn off to save power. The specific values ​​of the first and second preset values ​​can be selected according to actual needs.

[0070] The photosensitive element 44 can be disposed between the light-transmitting cover 51 and the main body 10, so that the light-transmitting cover 51 can provide protection for the photosensitive element 44 and prevent dust and dirt from accumulating on the photosensitive element 44.

[0071] In some embodiments, the doorbell may also include a front cover 52, which is disposed on the front side of the body 10 and covers the second circuit board 13 to protect the second circuit board 13.

[0072] In some embodiments, the doorbell also includes a ringing button 45 disposed on the front side of the main body 10, which can be used to control the doorbell to ring.

[0073] The ringing button 45, the trigger component 30, and the camera 21 are arranged sequentially along the length of the main body 10. The camera 21 can be set near the top of the main body 10, the ringing button 45 can be set near the bottom of the main body 10, and the trigger component 30 is located between the ringing button 45 and the camera 21, thereby preventing the ringing button 45, the trigger component 30, and the camera 21 from interfering with each other.

[0074] like Figure 11 and Figure 12 As shown, in some embodiments, the doorbell also includes at least two magnetic attachments 46. The magnetic attachments 46 are installed on the side of the main body 10 away from the camera 21, and all magnetic attachments 46 are arranged YY along the length of the main body 10. It should be noted that the side of the main body 10 away from the camera 21 is the rear side of the main body 10, which is opposite to the front side. Specifically, when the doorbell is installed on a door or wall, the rear side of the main body 10 faces inwards. The magnetic attachments 46 can be magnets, allowing the doorbell to be magnetically attached to an iron door or a wall containing iron, eliminating the need for screws or other components to install the doorbell. This avoids damage to the door or wall and facilitates user installation and adjustment of the doorbell's position. The number of magnetic attachments 46 can be two, three, or more.

[0075] In some embodiments, the doorbell also includes a rear cover 53, which covers the rear side of the main body 10, and the magnetic member 46 can be installed on the rear side of the rear cover 53.

[0076] In some embodiments, the doorbell may further include an adhesive strip 47, which is attached to the rear side of the back cover 53 and covers the magnetic member 46. The adhesive strip 47 may be formed of silicone. The adhesive strip 47 can hide the magnetic member 46 inside the doorbell, preventing the magnetic member 46 from colliding with other objects during the installation of the doorbell. The adhesive strip 47 may also have better flatness, so that the adhesive strip 47 can better adhere to the door or wall.

[0077] In some embodiments, an unlocking button 48 may be provided on the rear side of the main body 10. The unlocking button 48 can be connected to the door lock. After confirming the identity of the visitor outside the door, the user can press the unlocking button 48 to open the door if he / she wants to open the door.

[0078] In some embodiments, a memory card slot 49 may be provided on the rear side of the main body 10. The memory card slot 49 can be used to insert a memory card to store information such as image information captured by the camera 21, thereby enabling local storage without the need for cloud storage and preventing privacy leaks. The memory card can be of the type SD card (Secure Digital Card, non-volatile memory card).

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
