Abstract
Description
Technical Field
[0001] The present application relates to the field of shooting fill light technology, and in particular to a camera device and a video doorbell. Background Art
[0002] In recent years, with the development of video imaging technology and communication technology, camera devices have been widely used in more and more fields, such as smart home, security monitoring and other fields.
[0003] In order to ensure the safety of the living environment, people usually install monitoring equipment in front of the door for surveillance. The monitoring equipment can be an independent monitor or a video doorbell that has both monitoring and visitor notification functions. Whether it is a monitor or a video doorbell, it uses a camera device that captures video images to monitor the living environment.
[0004] When capturing video images, if there's insufficient ambient light, a camera typically requires infrared or white light fill to ensure brightness and clarity. Because the fill light intensity and range of a single infrared or white light source are limited, existing technologies often employ multiple light sources aligned in a common direction. While this approach can improve fill light intensity and expand the fill light range to a certain extent, the extent to which this range is expanded is limited. Furthermore, the superposition of light from multiple light sources can easily lead to uneven light intensity distribution. Utility Model Content

[0059] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.
[0060] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.
[0061] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.
[0062] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.
[0063] First see Figure 1 Taking two fill light sources 10 with the same divergence angle α, facing the same direction (i.e., the optical axes are parallel to each other) and spaced apart by a distance D as an example, the dotted line in the figure represents the optical axis of the corresponding fill light source 10, the dotted line represents the light emitted by the fill light source 10, and the straight line represents the light receiving surface. As can be seen from the figure, although the two fill light sources 10 arranged in an arrangement can increase the light receiving area, the total field of view angle of the light emitted by the two fill light sources 10 is still α, so the increase in the fill light range is limited. In addition, from Figure 1 It can also be seen in the figure that the two fill light sources 10 with the same direction have a higher energy density of their optical axis accessories. Therefore, on the light receiving surface, the light intensity at the intersection with the optical axis is much higher than that at other positions, resulting in uneven fill light and affecting the lens acquisition effect.
[0064] In this regard, after research and practice, this application adopts fill light sources arranged in an inclined manner to greatly increase the fill light range and make the fill light more uniform. For the specific principle, please refer to Figure 2, also take two fill light sources 10 with the same divergence angle α and the distance D as an example, each fill light source 10 is tilted towards each other at an angle β. After setting this up, please further combine Figure 3 , the total viewing angle of the light emitted by the two fill light sources 10 increases to γ = 2*[(1 / 2)α+β] = α+2β, and the fill light range is greatly improved. In addition, if Figure 2 As shown in , after such setting, the overall distribution of light in the middle of the light-receiving area can be more uniform, and the middle of the light-receiving area is basically the middle area collected by the lens, so the imaging effect can also be guaranteed.
[0065] Based on the above principles, according to one aspect of an embodiment of the present application, a camera device is provided, which can be applied to a video doorbell, a monitor, etc. The specific details are not limited here. The following text and the accompanying drawings mainly use a video doorbell as an example for explanation.
[0066] First see Figure 4 and Figure 5 , Figure 4 The overall structure of the camera device is shown in FIG. Figure 5 Figure 1 shows the structure of a camera device in a partially exploded state. The camera device 100 includes a main body 110, a lens assembly 120, a first fill light 130, and a second fill light 140. The main body 110 is the main structure of the camera device 100, generally including a housing and internal circuit structures. The lens assembly 120 is used to cooperate with the photosensitive chip inside the main body 110 to capture video images. The first fill light 130 and the second fill light 140 can be infrared LEDs or white light LEDs, and the specific details are not limited here.
[0067] like Figure 4 As shown in FIG, the lens assembly 120 is at least partially disposed in the main body 110 and faces the front side of the main body 110. The “front side” refers to Figure 4 The side of the middle body 110 facing the direction indicated by arrow A, that is, the direction indicated by arrow A is the direction of the lens assembly 120. Correspondingly, the "rear side" mentioned below is the side of the corresponding component facing the opposite direction indicated by arrow A.
[0068] like Figure 5 As shown in FIG, the first fill light 130 and the second fill light 140 are both at least partially disposed in the main body 110, and the first fill light 130 and the second fill light 140 are tilted along the first direction (in the Figure 5 In the embodiment shown, the optical axes (in the direction indicated by the double arrow X) of the first and second fill light members 130 and 140 are arranged toward each other and toward the front side of the main body 110. Figure 5The dot-dash lines on the first fill light 130 and the second fill light 140 will intersect at the front side.
[0069] like Figure 6 In the simplified perspective structure shown in FIG, the lens assembly 120 captures a first angle θ1 along a first direction (the direction indicated by the double arrow X in the figure). After the first fill light 130 and the second fill light 140 are arranged in the above manner, the illumination field of the first fill light 130 and the illumination field of the second fill light 140 are superimposed on each other, and the superimposed illumination field is an angle θ1. a In the specific embodiment shown in the figure, θ a >θ1, of course, in other embodiments, it can also be set to θ a =θ1.
[0070] based on Figure 6 The relationship between the collection field of view of the lens assembly 120 shown in FIG. 1 and the illumination field of view after the first fill light 130 and the second fill light 140 are superimposed, and combined with 2 and the above Figure 2 From the explanation of the optical principle, it can be concluded that by adopting the first fill light component 130 and the second fill light component 140 to be arranged toward each other in a tilted manner along the first direction, not only can the fill light range cover the entire collection field of view of the lens assembly 120 along the first direction, but also the fill light in the middle area within the field of view of the lens assembly 120 can be made more uniform, thereby improving the imaging effect.
[0071] It should be noted that, in the specific embodiment shown in the figure, the structure display and principle explanation are carried out with the first direction as the horizontal direction, which does not constitute a specific limitation on the first direction. In some other embodiments, the first direction can also be a vertical direction or an inclined direction, and the principle of fill light is the same.
[0072] In order to further improve the acquisition effect of the lens assembly 120, as shown in FIG. Figure 7 As shown in the center front view, the lens assembly 120 can be positioned so that its axis (point O in the figure) is located on the perpendicular bisector (dash-dotted line in the figure) of the line connecting the first fill light 130 and the second fill light 140 (the dashed line segment between the two in the figure). This arrangement ensures that the light emitted by the first fill light 130 and the second fill light 140 is symmetrical on both sides, further ensuring that the central area of the video image captured by the lens assembly 120 has higher brightness and more uniform overall brightness, thereby improving the video image capture effect.
[0073] See also Figure 8As shown in the side structure, for the fill light situation along the second direction (the direction indicated by the double arrow Z in the figure), the collection field of view of the lens assembly 120 along the second direction is the second angle θ2, and the illumination fields of the first fill light component 130 and the second fill light component 140 along the second direction are both greater than or equal to θ2.
[0074] exist Figure 8 In the specific embodiment shown, the illumination fields of the first fill light 130 and the second fill light 140 along the second direction are both θ b , and θ b =θ2, this setting can effectively fill in the main area captured by the lens assembly 120. In addition, it can also be set to θ b >θ2, so that the first fill light 130 and the second fill light 140 can fill light for more areas or all areas within the field of view of the lens assembly 120.
[0075] In order to ensure that the lens assembly 120 has a larger acquisition field of view, such as Figure 9 As shown in the structure of the enlarged part in the figure, the lens assembly can be arranged to protrude from the outer surface of the main body 110. On this basis, if the strong light emitted by the first fill light 130 or the second fill light 140 directly hits the protruding part of the lens assembly 120, it will cause the image to be overexposed at the corresponding position, making it impossible to clearly capture the video image. In order to solve this problem, as shown in FIG. Figure 9 As shown, a light-blocking ring 150 may be provided on the periphery of the portion of the lens assembly 120 protruding from the outer surface of the main body 110, and the light emitted by the first fill light 130 and the second fill light 140 (such as Figure 9 The light (shown by the middle dotted line) will not directly hit the lens assembly 120 due to the blocking of the light blocking ring 150, thereby avoiding overexposure.
[0076] According to another aspect of the embodiment of the present application, a video doorbell is also provided. Figure 4 The video doorbell 100a includes the camera device 100 provided in any of the above embodiments. In addition, please further combine Figure 12 The figure shows the internal structure of the main body 110 in the exploded state. As shown in the figure, the video doorbell 100a also includes a main board 112 and a flexible circuit board 114. The main board 112 and the flexible circuit board 114 are both arranged in the shell 111 of the main body 110, and the first fill light 130 and the second fill light 140 are both electrically connected to the main board 112 through the flexible circuit board 114.
[0077] In the video doorbell 100a, the flexible circuit board 114 is electrically connected to the main board 112, and by utilizing the bendable and deformable ability of the flexible circuit board 114, at least a portion of the flexible circuit board 114 is tilted. The first fill light 130 and the second fill light 140 are mounted and fixed on the tilted portion of the flexible circuit board 114 and electrically connected. This allows the first fill light 130 and the second fill light 140 to be assembled and fixed in a tilted manner while achieving electrical connection with the main board 112.
[0078] Compared to existing mechanical doorbells or push-button doorbells, the video doorbell 100a can be used not only as a doorbell but also for door monitoring, such as visitor reminders and remote video. When a visitor arrives, the homeowner can see the visitor on the screen of the device inside the house or on the mobile phone.
[0079] When the video doorbell 100a uses the camera device 100 provided by the above embodiment for monitoring and fill lighting, the fill lighting range can cover the entire monitoring field along the first direction, ensuring the reliability of video monitoring. At the same time, since the fill lighting is relatively uniform, the imaging consistency of the video monitoring is better in dim environments.
[0080] Most current video doorbells have a 4:3 screen ratio, with the camera's horizontal field of view being around 130°, the vertical field of view being around 100°, and the tilted field of view being around 180°. Due to their limited vertical field of view, such video doorbells sometimes cannot clearly see visitors from head to toe. Figure 10 As shown in the figure, the doorbell 20 is conventionally installed at a height of 1.2m. When a visitor is 0.5m in front of the doorbell 20, he can only see the image of the area between points M1 and M2, that is, the image of the area between 0.6m and 1.8m in height. This not only makes it impossible to see the visitor's feet, but also makes it impossible to see the visitor's head for visitors over 1.8m tall.
[0081] In this regard, Figure 11 As shown in the specific embodiment shown in the figure, the video doorbell 100a adopts a lens assembly 120 with an aspect ratio of 1:1, a horizontal field of view of 150°, a vertical field of view of 150°, and an oblique field of view of 180°, so as to Figure 10 After arranging the video doorbell 100a in the same manner, when a visitor is 0.5m in front of the video doorbell 100a, the screen will show a 3m height image, so the visitor's entire body can be fully seen. The fill light method provided in this application can provide uniform and effective fill light when the video doorbell 100a is working at night.
[0082] Since the first fill light 130 and the second fill light 140 of the camera device 100a are arranged in an inclined manner toward each other, the assembly and fixation of the first fill light 130 and the second fill light 140 on the main body 110 and the electrical connection thereof become more complicated and difficult, the present application further proposes an embodiment. For details, please refer to Figure 12 , the front side of the main board 112 is provided with a bracket 113, please further combine Figure 13 The structure of the bracket 113 shown in the figure is in an exploded state. The front side of the bracket 113 is a mounting surface 1131. The mounting surface 1131 has a first inclined surface 1131a and a second inclined surface 1131b. The first inclined surface 1131a and the second inclined surface 1131b are arranged at an angle toward each other along a first direction (indicated by the double arrow X in the figure). The flexible circuit board 114 is attached to the mounting surface 1131. The first fill light 130 is disposed on the flexible circuit board 114 at a location that aligns with the first inclined surface 1131a. The second fill light 140 is disposed on the flexible circuit board 114 at a location that aligns with the second inclined surface 1131b.
[0083] Specifically, during the processing and forming of the bracket 113 , the first inclined surface 1131 a and the second inclined surface 1131 b on the bracket 113 may be processed accordingly according to the required inclination angles of the first fill light 130 and the second fill light 140 .
[0084] During assembly, the bracket 113 can be first fixed to the main board 112 by welding, screw fastener connection, clamping or bonding, and then the first fill light 130 and the second fill light 140 can be fixed to the flexible circuit board 114 by welding or the like and electrically connected to the circuit on the flexible circuit board 114. Finally, the flexible circuit board 114 with the first fill light 130 and the second fill light 140 can be attached to the mounting surface 1131 of the bracket 113, and the first fill light 130 and the second fill light 140 can be attached to the first oblique surface 1131 of the mounting surface 1131 respectively. The surface 1131a corresponds to the second inclined surface 1131b. The flexible circuit board 114 can be fixed to the mounting surface 1131 by bonding, threaded fastener connection, etc. Finally, the conductive end of the flexible circuit board 114 is welded to the conductive end of the main board 112 to form an electrical connection. While completing the installation and fixation of the first fill light component 130 and the second fill light component 140 relative to the main board 112, the electrical connection between the first fill light component 130 and the second fill light component 140 and the main board 112 is achieved, ensuring that the first fill light component 130 and the second fill light component 140 work normally to provide fill light.
[0085] In this embodiment, in order to ensure the reliability of the installation and fixation of the first fill light component 130 and the second fill light component 140 on the main board 112, the bracket 113 is used to support and fix the first fill light component 130 and the second fill light component 140. On the one hand, it is relatively simple to process and form two opposing inclined surfaces (i.e., the first inclined surface 1131a and the second inclined surface 1131b) on the bracket 113, which will not cause an excessive increase in manufacturing costs. On the other hand, the assembly operation between the bracket 113 and the main board 112 and the two fill lights (i.e., the first fill light component 130 and the second fill light component 140) is also relatively easy, which is conducive to improving product assembly efficiency. On this basis, in order to ensure the stability of the circuit connection between the two fill light components and the main board 112, and taking into account the existence of the two inclined surfaces on the mounting surface 1131 of the bracket 113, a flexible circuit board 114 is adhered to the mounting surface 1131, and the first fill light component 130 and the second fill light component 140 are respectively arranged at the positions on the flexible circuit board 114 that adhere to the two inclined surfaces. In this way, the stability of the physical connection between the first fill light component 130 and the second fill light component 140 and the reliability of the circuit are simultaneously guaranteed, thereby achieving the reliability of the monitoring work of the video doorbell 100a.
[0086] In order to reduce the size of the video doorbell 100a and achieve product miniaturization, the present application also designs the internal circuit layout accordingly. For details, please refer to Figure 14 and Figure 15 , Figure 14 The structure of the video doorbell 100a is shown in the exploded state. Figure 15 Shown Figure 14 In the enlarged structure at P, the main body 110 further includes a sensor board 115 disposed within the housing 111. The sensor board 115 is parallel to the main board 112 and disposed behind the main board 112. The sensor board 115 is electrically connected to the main board 112. The lens assembly 120 is disposed in front of the sensor board 115 and extends through the main board 112 and the housing 111 in sequence.
[0087] Specifically, a photosensitive chip is integrated on the sensor board 115, and a microcontroller unit 1123 (MCU) is provided on the main board 112. The photosensitive chip converts the light collected by the lens assembly 120 into an electrical signal, and then sends it to the microprocessor 1123 of the main board 112 through the sensor board 115 for imaging processing.
[0088] In this embodiment, the sensor board 115 is arranged parallel to the rear side of the main board 112, and the lens assembly 120 is arranged in front of the sensor board 115 and passes through the main board 112 and the housing 111 in sequence. Compared with the method of directly arranging the lens assembly 120 on the main board 112, the circuit structure on the main board 112 can be simplified, that is, the area required for the main board 112 can be reduced. Compared with the method of arranging the sensor board 115 on the front side of the main board 112, the lens assembly 120 can utilize the space between the sensor board 115 and the main board 112, thereby reducing the overall thickness of the product.
[0089] Furthermore, if Figure 15 As shown in FIG, the video doorbell 100a may further include an infrared sensor component 160, which may be, for example, a passive infrared sensor (PIR sensor). The infrared sensor component 160 is electrically connected to the mainboard 112, and a window ( ) is provided on the housing 111 for the infrared sensor component 160 to detect the field of view outside the door. Figure 14 The field of view outside the door refers to the area in front of the door that the front side of the video doorbell 100a faces. When a visitor arrives at the door, the infrared sensor component 160 can automatically detect and identify the visitor.
[0090] exist Figure 15 In the specific embodiment shown, the video doorbell 100a is provided with a sensor board 115 and an infrared sensor component 160. In order to achieve infrared monitoring of the human body while meeting the requirements of product miniaturization, the infrared sensor component 160 is arranged on the front side of the sensor board 115. The infrared sensor component 160 is electrically connected to the main board 112 through the sensor board 115, and windows for the infrared sensor component 160 to detect are provided on the main board 112 and the housing 111 (such as the infrared sensor component 160). Figure 15 The first window 1121 and Figure 14 The second window 1111 in FIG.
[0091] By arranging an infrared sensing component 160 on the front side of the sensor board 115, and providing a first window 1121 and a second window 1111 on the main board 112 and the shell 111 for the infrared sensing component 160 to receive infrared radiation, the video doorbell 100a can monitor human activities while meeting the requirements of product miniaturization.
[0092] In a dim environment, the pupil of the human eye will dilate. At this time, if a large amount of light emitted by the first fill light 130 and the second fill light 140 entering the human eye is reflected onto the lens assembly 120, it will cause a red-eye phenomenon in the image, affecting the user experience. To this end, it is possible to consider increasing the incident angle of light entering the human eye so that the light reflected back from the human eye at a larger reflection angle will not enter the lens assembly 120 in large quantities. Specifically, if Figure 15 As shown in , in some embodiments of the present application, the infrared sensor component 160 is disposed between the line connecting the first fill light 130 and the second fill light 140 and the lens assembly 120, so that the lens assembly 120 is separated from the first fill light 130 and the second fill light 140.
[0093] After the lens assembly 120 is separated from the first fill light 130 and the second fill light 140 by the infrared sensor assembly 160, the distance between the first fill light 130 and the lens assembly 120, as well as the distance between the second fill light 140 and the lens assembly 120, is increased. Therefore, when the human eye is at a position similar to the height of the lens assembly 120, the incident angle of the light emitted by the first fill light 130 and the second fill light 140 when entering the human eye is larger. Accordingly, the light reflected back by the human eye will be more directed toward the upper side of the lens assembly 120, thereby reducing the red-eye phenomenon in the imaging.
[0094] In addition, instead of using the infrared sensor assembly 160 to separate the lens assembly 120 from the first fill light 130 and the second fill light 140, the red-eye phenomenon can be reduced by directly increasing the distance between the lens assembly 120 and the first fill light 130 and the second fill light 140. Taking the video doorbell 100a installed at a height of 1.2m as an example, it has been verified in practice that the distance between the lens assembly 120 and the first fill light 130 and the second fill light 140 can be designed to be greater than or equal to 2cm to reduce the red-eye phenomenon.
[0095] Regarding the assembly of the infrared sensor assembly 160, the first fill light 130 and the second fill light 140 in the housing 111, the present application further proposes an implementation method, specifically as follows: Figure 14 and 15 As shown in FIG, the housing 111 includes a front shell 111a and a rear shell 111b, which are assembled in a mutually buckled manner. A lens cover 1113 is provided on the front shell 111a at the periphery of the lens assembly 120, an infrared lens 1114 is provided at a position opposite to the infrared sensor assembly 160, and a light-transmitting member 1115 is provided at a position opposite to the first fill light member 130 and the second fill light member 140. The position on the front shell 111a opposite to the infrared sensor assembly 160 refers to: the position of the infrared sensor assembly 160 along its direction (i.e., the position of the infrared sensor assembly 160). Figure 4The projection of the first fill light 130 and the second fill light 140 on the front housing 111a and the area near the projection are similar.
[0096] In this embodiment, the lens assembly 120, the infrared sensor assembly 160, the first fill light 120 and the second fill light 130 are assembled in the housing 111 by interlocking the front shell 111a and the rear shell 111b. At the same time, a lens cover 1113 is provided on the front shell 111a at the periphery of the lens assembly 120, an infrared lens 1114 is provided at a position opposite to the infrared sensor assembly 160, and a light-transmitting member 1115 is provided at a position opposite to the first fill light 130 and the second fill light 140, so as to ensure that their corresponding functions are realized while also being able to reliably protect the internal structure.
[0097] The video doorbell 100a provided in the embodiment of the present application can be a charging type product. Based on this, Figure 14 and Figure 15 As shown, the main body 110 also includes a power board 116, a battery 117, and a charging board 118, which are disposed within the housing 111. To optimize the layout of these components and achieve product miniaturization, in the illustrated embodiment, the power board 116 is positioned parallel to the sensor board 115 and behind the sensor board 115 to minimize space occupied in the thickness direction (i.e., perpendicular to the main board 112). Given that the main board 112 is larger than the sensor board 115 and the power board 116, the battery 117 is positioned behind the main board 112, at one end of the sensor board 115 and the power board 116. This ensures that the battery 117, the sensor board 115, and the power board 116 share a certain thickness dimension. Since the charging board 118 has a single function and a relatively small circuit board area, it is positioned behind the main board 112, perpendicular to the main board 112, and between the sensor board 115 and the battery 117. After being arranged in this manner, the internal space of the shell 111 can be fully utilized, making the internal structure layout compact, meeting the requirements of product miniaturization, and facilitating packaging, transportation, etc.
[0098] Please continue reading Figure 15 The charging plate 118 is provided with a charging port 1181 exposed to the housing 111. The charging port 1181 can be Figure 15 As shown in FIG, it is fixed parallel to the charging plate 118 and exposed from the rear side of the housing 111. Of course, other arrangements can also be used and are not limited here. The charging port 1181 is electrically connected to the battery 117 to enable charging of the battery from an external power source. The power board 116 is electrically connected to the battery 117 and the mainboard 112 respectively to supply power to various circuits via the battery 117.
[0099] In addition, as a video doorbell 100a, a button can also be set on the main body 110, and the homeowner can be notified by pressing the button when a visitor arrives. Regarding the setting of the button, this application proposes an implementation method, please refer to Figure 16 The structure in the explosion state shown in FIG. 1 , the video doorbell 100a further includes a button 170 and a switch contact 171, wherein the button 170 is provided on the main body 110, and the switch contact 171 is provided inside the main body 110 and corresponds to the position of the button 170, as shown in FIG. Figure 17 As shown in Figure 16 In the enlarged structure at Q, a plurality of light-emitting members 180 are provided on the periphery of the switch contact 171, and each light-emitting member 180 is provided in a direction away from the switch contact 171, that is, the light-emitting member 180 emits light in a direction away from the switch contact 171 along the direction indicated by the dotted arrow in the figure, and a light-distributing member 181 is provided on the periphery of the light-emitting member 180, for example, a light-distributing sheet, etc. The periphery of the button 170 has a light-transmitting portion 172 (such as Figure 4 As shown in FIG, the light emitted by the light emitting element 180 is homogenized by the light homogenizing element 181 and then emitted from the light transmitting portion 172 .
[0100] exist Figure 16 In the specific embodiment shown, the button 170 includes a button silicone 173, a pressing plate 174, and a button cover 175. The button silicone 173 covers the switch contact 171 and the light homogenizer 181. The pressing plate 174 is arranged on the front side of the button silicone 173. The button cover 175 is embedded in the front side of the pressing plate 174. The button silicone 173 is responsible for pressing the switch contact 171 when pressed and for rebounding after pressing. The pressing plate 174 is responsible for the overall structural strength of the button. Among them, the button silicone 173 and the pressing plate 174 can both be made of transparent materials, while the button cover 175 is made of non-transparent materials. The pressing plate 174 is located at the edge of the button cover 175 to form a light-transmitting portion 172, so that the light homogenized by the light homogenizer 181 is emitted from the position on the pressing plate 174 at the edge of the button cover 175. At night or in dim conditions, uniform light is emitted from the light-transmitting portion 172 of the pressing plate 174 located at the edge of the button cover 175, providing a comfortable and soft lighting effect and marking the position of the button 170, ensuring that visitors can quickly confirm the position of the button 170 and press the doorbell in time to notify the homeowner of their visit.
[0101] In addition to the method provided in the above embodiment in which the light-transmitting portion 172 is formed by the pressing plate 174 being located at the edge of the key cover 175, the key 170 can also be designed through two-color injection molding to have an opaque middle area and a transparent structure at the outer edge, so that the light-transmitting portion 172 is formed by the transparent part at the outer edge. Of course, a gap can also be left between the key 170 and the main body 110, and the light-transmitting portion 172 is formed by the gap. The specific light-transmitting method is not limited here.
[0102] Finally, in order to more fully illustrate the video doorbell 100a provided by this application, a preferred embodiment is introduced below. Figure 18 and Figure 19 The exploded structure shown from the front and back perspectives shows that the video doorbell 100a is an overall vertically elongated strip. The interior of the front shell 111a and the rear shell 111b forms a space for the main board 112, sensor board 115, power board 116, battery 117, and charging board 118. A sealing ring 119 is sandwiched at the joint between the front shell 111a and the rear shell 111b. The interference fit of the sealing ring 119 seals the joint between the two, ensuring the reliability of the internal circuit structure. A power switch 1161 is located on the back of the power board 116. Pressing the power switch 1161 from the back of the rear shell 111b turns the video doorbell 100a on and off.
[0103] To achieve the call function, a speaker 190 is further provided at the bottom of the battery 117 . Sound holes 1112 are opened on the front shell 111 a and the rear shell 111 b at positions opposite to the speaker 190 to ensure that the sound of the speaker 190 is emitted from the housing 111 .
[0104] Considering that the video doorbell 100a is typically mounted on the side of a door, in order to adjust the field of view of the lens assembly 120 to the area in front of the door, the video doorbell 100a also includes an angle adjustment bracket 200. The back of the angle adjustment bracket 200 is inclined. When the back of the angle adjustment bracket 200 is attached to the wall on the side of the door, the lens assembly 120 is tilted toward the area in front of the door, thereby enabling recording and monitoring of the area in front of the door. The angle adjustment bracket 200 can also be fastened to the back of the rear housing 111b via a quick-release buckle structure, making it easy to remove the main body 110 from the angle adjustment bracket 200 for charging and maintenance.
[0105] Furthermore, please combine Figure 14 and Figure 18The mainboard 112 may also include an ambient light sensor 1122 and a microprocessor 1123. The ambient light sensor 1122 is located on the front side of the mainboard 112 and is electrically connected to the microprocessor 1123. The location of the microprocessor 1123 on the mainboard 122 is not limited herein. Specifically, the ambient light sensor 1122 sends the detected ambient light intensity to the microprocessor 1123. The microprocessor 1123 determines whether the detection result is less than a preset threshold. If the detection result is less than the preset threshold, it indicates that the video doorbell 100a is currently in a dim environment. At this time, the microprocessor 1123 controls the first fill light 130 and the second fill light 140 to turn on to provide fill light, thereby ensuring the imaging effect.
[0106] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of this application and are not intended to limit them. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they may modify the technical solutions described in the above embodiments or replace some or all of the technical features therein with equivalents.
