[0053] Please refer to Figures 1 to 7 The present application proposes a monitoring device 100. In one embodiment of the present application, the monitoring device 100 proposed in the present application includes a housing 10, a camera module 20 and a white light module 30; wherein, the housing 10 is provided with a first cavity 10a and a second cavity 10b that are isolated from each other, and an exposure port 10c connected to the first cavity 10a; the camera module 20 is arranged in the first cavity 10a and is arranged corresponding to the exposure port 10c; the white light module 30 is arranged in the second cavity 10b, and at least a portion of the cavity wall of the second cavity 10b is made of a light-transmitting material.

[0054] The housing 10 can serve as a carrier structure for the camera module 20, the white light module 30, and other components of the monitoring device 100. The housing 10 can be in any shape, such as a sphere, a near-sphere, an ellipsoid, or a cylinder. Furthermore, when the monitoring device 100 is placed on a support surface such as a desktop during normal use, the direction perpendicular to the support surface can be defined as the up-down direction. In this case, the first cavity 10a within the housing 10 can be located above the second cavity 10b, allowing the camera module 20 to be positioned relatively high, thereby reducing the possibility of the camera module 20's viewing angle being obstructed by the support surface such as the desktop. Furthermore, because the exposure port 10c for the camera module 20 to capture external images is also located at the top of the housing 10, corresponding to the camera module 20, a complete aperture is formed at the bottom of the housing 10 away from the exposure port 10c, thereby enhancing the fill illumination effect of the white light module 30 on the environment surrounding the monitoring device 100. Furthermore, the first cavity 10a and the second cavity 10b are arranged sequentially in the vertical direction, which can fully utilize the vertical space and reduce the area occupied by the monitoring device 100 on a support surface such as a desktop. Of course, it should be noted that in other embodiments, the first cavity 10a and the second cavity 10b can also be arranged sequentially in a horizontal direction, and this application does not limit the relative positional relationship between the first cavity 10a and the second cavity 10b.

[0055] The camera module 20 can be used to shoot the environment in which the monitoring device 100 is located, so as to realize the basic functions of the monitoring device 100. Among them, since the shooting principle of the camera module 20 is a prior art, the structure of the camera module 20 will not be described in detail here. In addition, the camera module 20 can be fixedly set on the housing 10 so that the monitoring device 100 has a fixed shooting direction. Of course, in order to enrich the downward shooting direction of the monitoring device 100, the camera module 20 can also be rotatably set on the housing 10 as described below. For example: it can be rotatable only around a horizontal axis, or it can be rotatable only around a vertical axis, or it can be rotatable around both a horizontal axis and a vertical axis.

[0056] The white light module 30 can be used to emit white light to fill in the environment in which the monitoring device 100 is located, enabling the camera module 20 to capture full-color images. The light source 32 in the white light module 30 can be an LED lamp, which makes it relatively small and facilitates its installation and arrangement within the limited space within the housing 10. Of course, the light source 32 in the white light module 30 can also be an incandescent lamp. This application does not limit the structural type of the white light module 30. Furthermore, at least a portion of the cavity wall of the housing 10 that encloses the second cavity 10b is made of a translucent material. This means that the housing 10 can be partially or entirely made of a translucent material. Translucent materials include transparent materials, such as polycarbonate or acrylic, and can also include colored translucent materials, such as white acrylonitrile-butadiene-styrene copolymer or colored glass.

[0057] When the monitoring device 100 of the technical solution of the present application is in use, when the light in the environment is poor, for example, at night, the white light module 30 of the monitoring device 100 can be turned on. Since the white light module 30 is arranged on the inner side of the housing 10 of the monitoring device 100, it needs to emit light outward through the light-transmitting part of the housing 10 of the monitoring device 100. At this time, it can provide relatively soft fill light for the environment in which the monitoring device 100 is located, so that the camera module 20 can capture full-color images. Therefore, the structural setting of the monitoring device 100 in this solution achieves low-light full-color night vision, which can reduce the possibility of image distortion and improve the quality of the monitoring image. In addition, the monitoring device 100 in this solution also arranges the camera module 20 and the white light module 30 in the first cavity 10a and the second cavity 10b of the housing 10, respectively. In this way, the camera module 20 and the white light lamp module 30 are arranged in separate chambers, which can reduce the possibility of light pollution caused by the white light lamp module 30 to the inner side of the housing 10.

[0058] Please refer to Figure 1 、 Figure 3 as well as Figure 7 In one embodiment of the present application, the housing 10 includes an upper shell 11, a lower shell 12 and a bracket 13. The upper shell 11 covers the lower shell 12, and the bracket 13 is arranged in the upper shell 11 and / or the lower shell 12; the upper shell 11 and the bracket 13 enclose a first cavity 10a, the exposure port 10c is arranged in the upper shell 11, and the camera module 20 is connected to the bracket 13; the lower shell 12 and the bracket 13 enclose a second cavity 10b, and the lower shell 12 is made of a light-transmitting material.

[0059] The upper shell 11 can be provided with an opening at its lower end, while the lower shell 12 can be provided with an opening at its upper end. When the upper shell 11 and the lower shell 12 are covered, they can enclose a cavity, and the bracket 13 can be located within the cavity. In this case, the bracket 13 can be partially housed within the upper shell 11 and partially housed within the lower shell 12. Of course, the bracket 13 can also be fully housed within the upper shell 11 or the lower shell 12.

[0060] In this embodiment, the housing 10 is separated into an upper housing 11, a lower housing 12, and a bracket 13, so that each part can be manufactured independently and then assembled together. The structure of the separated upper housing 11, lower housing 12, and bracket 13 is relatively simple, which facilitates the formation of the first cavity 10a and the second cavity 10b.

[0061] In one embodiment of the present application, the lower shell 12 is made of white light-transmitting material.

[0062] In this embodiment, the lower housing 12 is constructed of a white, translucent material, such as white acrylonitrile-butadiene-styrene copolymer or white glass. This ensures that the lower housing 12 is translucent enough to allow light emitted by the white light module 30 located within the lower housing 12 to pass through. Furthermore, when the white light module 30 is closed, the lower housing 12 can visually block the white light module 30 and other structures within it. In other words, the white light module 30 and other structures within the lower housing 12 are not visible from the outside, thereby improving the consistency and aesthetics of the monitoring module's appearance. Furthermore, the use of white color also improves light utilization, thereby enhancing the luminous effect of the white light module 30.

[0063] In one embodiment of the present application, the upper shell 11 and the lower shell 12 are made of the same material.

[0064] In this embodiment, the material of the upper shell 11 and the lower shell 12 are set to be the same, for example, both are the white light-transmitting material described above, which can further improve the consistency of the appearance of the monitoring device 100 and further enhance the aesthetic effect. In addition, this can also allow the upper shell 11 and the lower shell 12 to be manufactured using the same raw materials, which further facilitates their manufacturing.

[0065] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the camera module 20 is rotatably connected to the bracket 13 around a horizontal axis.

[0066] In this embodiment, the camera module 20 is configured to rotate around a horizontal axis, so that the camera module 20 can rotate in a vertical plane to adjust the shooting angle of the camera module 20 and improve the monitoring effect. The rotation of the camera module 20 can be manually driven by the user. At this time, a damping member made of rubber or silicone that can undergo elastic deformation can be provided between the camera module 20 and the bracket 13, so that the camera module 20 can be limited and maintained by the damping force given by the damping member after it is rotated into place. Of course, the monitoring device 100 may also include a first driving member 50 (which can be a rotating motor or a rotating cylinder, etc.) to drive the camera to rotate around a horizontal axis through the first driving member 50. At this time, the intelligence level of the monitoring device 100 can be improved to improve the convenience of using the monitoring device 100.

[0067] Please refer to Figure 1 、 Figure 3 as well as Figure 7 In one embodiment of the present application, the housing 10 further includes a reflector 14, which is disposed in the second cavity 10b and enclosed with the lower housing 12 to form an installation cavity 10d; the white light lamp module 30 is disposed in the installation cavity 10d and is configured to emit light toward the reflector 14, and a light-shielding layer is provided on the side of the reflector 14 facing away from the white light lamp module 30.

[0068] In this embodiment, the reflector 14 encloses the lower housing 12 to form an inner cavity 10d for accommodating the white light module 30. This allows each inner surface of the inner cavity 10d to reflect light emitted by the white light module 30. This reflection from the inner surfaces of the inner cavity 10d improves the uniformity and softness of the light, ensuring that the white light module 30 provides fill light for the camera module 20 while simultaneously minimizing the impact on the environment surrounding the monitoring device 100. Providing a light-shielding layer on the side of the reflector 14 facing away from the white light module 30 further reduces the potential for light pollution inside the housing 10. The reflector 14 can be made of polyethylene terephthalate to enhance its reflective properties. In some embodiments, the reflector 14 can also be formed by laminating a reflective film to a substrate. The light shielding layer can be a black glue layer to improve the light shielding effect of the light shielding layer, as well as the convenience of arrangement and the stability of connection on the reflector 14. Of course, the light shielding layer can also be some opaque films.

[0069] Please refer to Figure 7In one embodiment of the present application, the lower shell 12 includes a bottom plate 121, an inner plate 122 and an outer plate 123, and the bracket 13 is connected to the bottom plate 121; the inner plate 122 is connected to the bottom plate 121, and the inner plate 122 surrounds the circumference of the bottom plate 121 and extends along the side of the bottom plate 121 facing the bracket 13; the outer plate 123 is connected to the bottom plate 121 and surrounds the outer side of the inner plate 122. The outer plate 123, the inner plate 122, the bottom plate 121 and the reflective plate 14 enclose a mounting cavity 10d.

[0070] In this embodiment, the lower shell 12 is configured to include a bottom plate 121, an inner plate 122, and an outer plate 123, so as to facilitate forming a luminous effect in the circumference of the lower shell 12. At the same time, it is also convenient to cooperate with the reflective plate 14 to form the installation cavity 10d. At this time, the transmission paths of some of the light emitted by the white light module 30 can be: the light emitted by the white light module 30 is irradiated by the reflector 14, then reflected to the inner panel 122, then reflected by the inner panel 122 to the outer panel 123, and then emitted from the outer panel 123; or the light emitted by the white light module 30 is irradiated by the reflector 14, then reflected by the reflector 14 to the outer panel 123, and then emitted from the outer panel 123; or the light emitted by the white light module 30 is irradiated by the outer panel 123, then reflected by the outer panel 123 to the reflector 14, then reflected by the reflector 14 to the outer panel 123, and then emitted from the outer panel 123, etc. It can be seen that the transmission paths of light are relatively diverse, and the uniformity and softness of light can be improved by multiple reflections of light.

[0071] In one embodiment of the present application, the surface of the lower shell 12 used to enclose and form the installation cavity 10d is a smooth surface.

[0072] In this embodiment, the surface of the lower shell 12 that encloses the mounting cavity 10d is smooth. For example, the inner side of the outer plate 123 and the outer side of the inner plate 122 are polished to achieve a smooth surface, thereby further enhancing light reflection. Similarly, in some embodiments, the surface of the reflector 14 that encloses the mounting cavity 10d is also smooth. Furthermore, in some embodiments, to enhance light diffusion, the outer surface of the outer plate 123 can be roughened. Furthermore, the outer plate 123 can be convexly curved, and the cross-sectional area enclosed by the outer plate 123 can decrease as the upper shell 11 approaches the lower shell 12. To achieve a good balance between the light reflection effect of the inner plate 122 and its regularity, the cross-sectional area enclosed by the inner plate 122 can be equal as the upper shell 11 approaches the lower shell 12.

[0073] In one embodiment of the present application, the reflective plate 14 is clamped between the lower shell 12 and the bracket 13 .

[0074] In this embodiment, the reflector 14 is fixed by clamping the lower shell 12 and the upper shell 11, so that the reflector 14 can be fixed by connecting the upper shell 11 and the lower shell 12. This simplifies the assembly of the monitoring device 100 and improves its assembly convenience.

[0075] In one embodiment of the present application, the white light lamp module 30 includes a lamp board 31 and multiple light sources 32. The lamp board 31 is a ring structure and surrounds the outer side of the inner plate 122. The multiple light sources 32 are arranged in sequence along the circumference of the lamp board 31.

[0076] In this embodiment, the light board 31 provides mounting locations for multiple light sources 32, allowing multiple light sources 32 to be installed on the light board 31 and then connected to the control board in the monitoring device 100. This eliminates the need to connect each of the multiple light sources 32 to the control board individually, thereby facilitating the electrical connection between the white light module 30 and the control board in the monitoring device 100. Furthermore, in terms of mechanical connection, multiple light sources 32 can be mounted on the light board 31 to form a single unit, which can then be installed in the lower housing 12 all at once, further facilitating the installation of multiple light sources 32 in the lower housing 12.

[0077] Please refer to Figure 3 and Figure 7 In one embodiment of the present application, the bottom plate 121 is provided with a receiving groove 121a, and the notch of the receiving groove 121a is arranged with its back facing the upper shell 11; the housing 10 also includes a base 15, the lower shell 12 is connected to the base 15, the base 15 extends into the receiving groove 121a, and covers the notch of the receiving groove 121a, and the base 15 is made of non-transparent material.

[0078] In this embodiment, the base 15 also shields the lower housing 12, effectively ensuring that the lower housing 12 emits light only in the designated light-emitting area. Inserting the base 15 into the receiving groove 121a of the bottom plate 121 improves the compactness of the two components, thereby reducing the overall size of the monitoring device 100. In particular, when the lower housing 12 is rotatably connected to the base 15 about a vertical axis, as described below, it is even more convenient to dispose the bearing 70 between the receiving groove 121a and the base 15.

[0079] Please refer to Figure 3 and Figure 7 In one embodiment of the present application, the lower shell 12 is rotatably connected to the base 15 around a vertical axis.

[0080] In this embodiment, the lower shell 12 is configured to rotate around a vertical horizontal axis, so that the camera module 20 can rotate in a horizontal plane to adjust the shooting angle of the camera module 20 and improve the monitoring effect. The rotation of the lower shell 12 can be manually driven by the user. At this time, a damping member made of rubber or silicone that can undergo elastic deformation can be provided between the lower shell 12 and the base 15, so that the lower shell 12 can be limited and maintained by the damping force given by the damping member after it is rotated into place. Of course, the monitoring device 100 may also include a second driving member 60 (which can be a rotating motor or a rotating cylinder, etc.) to drive the lower shell 12 to rotate around a vertical axis through the second driving member 60. At this time, the intelligence level of the monitoring device 100 can be improved to improve the convenience of using the monitoring device 100.

[0081] Please refer to Figure 2 as well as Figures 5 to 7 In one embodiment of the present application, the monitoring device 100 also includes a sound module 40, which is arranged in the first cavity 10a; the sound module 40 includes a frame 41 and a speaker 42 arranged on the frame 41, and the frame 41, the speaker 42 and the bracket 13 together form a rear sound cavity 40a, and the upper shell 11 is provided with a sound hole 11a at the position corresponding to the speaker 42.

[0082] In this embodiment, by providing a sound module 40, the monitoring device 100 facilitates playing sounds and interacting with users through voice. Furthermore, the sound module 40 is provided within the first cavity 10a, and the frame 41, speaker 42, and bracket 13 of the sound module 40 enclose a rear sound cavity 40a of the sound module 40, so that the space of the first installation cavity can be fully utilized to form a larger rear sound cavity 40a, thereby improving the bass effect and better meeting the high sound quality requirements of the interaction scene with infants and young children. In addition, the frame 41, speaker 42, and upper shell 11 can enclose the front sound cavity of the sound module 40, and the sound outlet 11a can be connected to the front sound cavity.

[0083] Please refer to Figure 3 、 Figure 4 as well as Figure 7 In one embodiment of the present application, to improve the compactness of the arrangement of the camera module 20 and the sound module 40 on the bracket 13, the bracket 13 may be provided with a first slot 13a, with the slot of the first slot 13a facing away from the lower housing 12. The camera module 20 is disposed within the first slot 13a, and the rear sound cavity 40a may be located on the side of the bracket 13 facing away from the first slot 13a. To facilitate the rotation of the camera module 20, the camera module 20 may be spherical, and the shape of the first slot 13a may also be configured to be spherical.

[0084] Please refer to Figures 5 to 7In one embodiment of the present application, in order to further expand the volume of the rear sound cavity 40a, the bracket 13 can also be provided with a second groove body 13b, the groove of the second groove body 13b faces the sound outlet 11a, and the bracket body 41 and the second groove body 13b enclose the rear sound cavity 40a.

[0085] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the sound outlet 11a and the exposure port 10c can be located on opposite sides of the upper shell 11, so that when the exposure port 10c faces forward, the sound outlet 11a can be located on the back side, making it less likely to be discovered and thus improving the aesthetics of the appearance of the monitoring device 100.

[0086] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
