[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 a revealing 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 revealing 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 be used as a carrier structure for the camera module 20, the white light module 30 and other components in the monitoring device 100. The housing 10 can be any shape such as spherical, approximately spherical, ellipsoidal or cylindrical. Further, when the monitoring device 100 is placed on a support surface such as a desktop in a normal use state, the direction perpendicular to the support surface such as the desktop can be defined as the up and down direction. At this time, the first cavity 10a in the housing 10 can be located above the second cavity 10b, so that the camera module 20 can have a relatively high position, thereby reducing the possibility that the shooting angle of the camera module 20 is blocked by the support surface such as the desktop. At the same time, since the exposure port 10c for the camera module 20 to shoot outward is also located at the top of the housing 10 corresponding to the camera module 20, it is convenient to form a complete aperture at the bottom of the housing 10 away from the exposure port 10c, so as to improve the fill light effect of the white light module 30 on the environment where the monitoring device 100 is located. In addition, the first cavity 10a and the second cavity 10b are arranged sequentially in the up-down direction, and the space in the up-down direction can be fully utilized to 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 the present application does not limit the relative position 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 is not 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 where the monitoring device 100 is located to achieve full-color shooting of the camera module 20. Among them, the light source 32 in the white light module 30 can be in the form of an LED lamp, so that the volume is relatively small, which is conducive to improving the convenience of its installation and arrangement in the limited space in the housing 10. Of course, the light source 32 in the white light module 30 can also be in the form of an incandescent lamp, and the present application does not limit the structural type of the white light module 30. In addition, at least part of the cavity wall of the housing 10 enclosed to form the second cavity 10b is made of a light-transmitting material, that is, the housing 10 can be partially made of a light-transmitting material, or it can be made of a light-transmitting material as a whole. Among them, the light-transmitting material includes a type of transparent material, such as: polycarbonate material or acrylic material, etc., and can also include a type of colored light-transmitting material, such as: white acrylonitrile-butadiene-styrene copolymer or colored glass, etc.

[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 a softer fill light for the environment where the monitoring device 100 is located, so that the camera module 20 can capture a full-color image. Therefore, the structural setting of the monitoring device 100 in this solution realizes the low-light full-color night vision effect, which can reduce the possibility of picture distortion and improve the quality of the monitoring picture. 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 housing 11, a lower housing 12 and a bracket 13. The upper housing 11 covers the lower housing 12, and the bracket 13 is disposed in the upper housing 11 and / or the lower housing 12; the upper housing 11 and the bracket 13 enclose a first cavity 10a, the exposure port 10c is disposed in the upper housing 11, and the camera module 20 is connected to the bracket 13; the lower housing 12 and the bracket 13 enclose a second cavity 10b, and the lower housing 12 is made of a light-transmitting material.

[0059] The upper shell 11 can be opened at the lower end, and the lower shell 12 can be opened at the upper end. When the two are covered, a cavity can be formed, and the bracket 13 can be located in the cavity. In this case, the bracket 13 can be partially accommodated in the upper shell 11, and the other part can be accommodated in the lower shell 12. Of course, the bracket 13 can also be fully accommodated in the upper shell 11, or fully accommodated in the lower shell 12.

[0060] In this embodiment, the housing 10 is split 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 split upper housing 11, the lower housing 12 and the bracket 13 is relatively simple, which is conducive to improving the convenience of forming 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 shell 12 is set to be a white light-transmitting material, such as white acrylonitrile-butadiene-styrene copolymer or white glass, so that the lower shell 12 can meet the light transmittance requirements, so as to allow the light emitted by the white light lamp module 30 located in the lower shell 12 to pass through. At the same time, when the white light lamp module 30 is closed, the lower shell 12 can play a visual blocking role for the white light lamp module 30 and other structures inside. That is, the white light lamp module 30 and other structures inside the lower shell 12 cannot be seen from the outside, which is conducive to improving the consistency of the appearance of the monitoring module and improving the aesthetics. In addition, the use of white can also improve the utilization rate of light, which is conducive to improving the luminous effect of the white light lamp 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 material of the lower shell 12 are set to be the same, for example, both are the white light-transmitting material introduced above, which can further improve the consistency of the appearance of the monitoring device 100 and further improve the aesthetic effect. In addition, this can also make the upper shell 11 and the lower shell 12 manufactured using the same raw materials, which is also conducive to improving the convenience of 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 be rotatable around a horizontal axis, so that the camera module 20 can be rotated in a vertical plane to adjust the shooting angle of the camera module 20 and improve the monitoring effect. Among them, 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.), so as 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 also includes a reflector 14, which is disposed in the second cavity 10b and is 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 shading 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 can be used to enclose the lower shell 12 to form an installation cavity 10d for accommodating the white light module 30, so that each inner surface of the installation cavity 10d can reflect the light emitted by the white light module 30. At this time, through the reflection of each inner surface of the installation cavity 10d, the uniformity and softness of the light can be improved to ensure the fill light effect of the white light module 30 on the camera module 20, while not causing too much impact on the environment where the monitoring device 100 is located. And a light shielding layer is provided on the side of the reflector 14 facing away from the white light module 30, which can further reduce the possibility of light pollution on the inner side of the housing 10. Among them, the material of the reflector 14 can be polyethylene terephthalate to improve the reflection effect of the reflector 14. Of course, in some embodiments, the reflector 14 can also be formed by bonding a reflective film on the 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, 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, and 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 that a luminous effect is formed in the circumference of the lower shell 12. At the same time, it is also convenient to cooperate with the reflective plate 14 to enclose 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 irradiates the reflector 14, then the light is reflected to the inner plate 122, then the inner plate 122 reflects it to the outer plate 123, then it is emitted from the outer plate 123; or, the light emitted by the white light module 30 irradiates the reflector 14, then the reflector 14 reflects it to the outer plate 123, then it is emitted from the outer plate 123; or, the light emitted by the white light module 30 irradiates the outer plate 123, then the outer plate 123 reflects it to the reflector 14, then the reflector 14 reflects it to the outer plate 123, then it is emitted from the outer plate 123, etc. It can be seen that the transmission paths of light are more diverse, so the uniformity and softness of the light can be improved by multiple reflections of the 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 used to enclose and form the installation cavity 10d is a smooth surface, for example, the inner side of the outer plate 123 and the outer side of the inner plate 122 are polished to make them smoother, which is conducive to further improving the reflection effect of light. Similarly, in some embodiments, the surface of the reflector 14 used to enclose and form the installation cavity 10d is also a smooth surface. In addition, in some embodiments, in order to improve the radiation diffusion effect of light, the outer surface of the outer plate 123 can be a rough surface. Even, the outer plate 123 can also be a convex arc plate, and the cross-sectional area enclosed by the outer plate 123 can be reduced in the direction where the upper shell 11 approaches the lower shell 12. In order to better take into account the reflection effect of the inner plate 122 on light and the regularity of the inner plate 122, the cross-sectional area enclosed by the inner plate 122 can be equal in the direction where 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 clamped and fixed by the lower shell 12 and the upper shell 11, so that the reflector 14 can be fixed while connecting the upper shell 11 and the lower shell 12. This can simplify the assembly of the monitoring device 100, thereby facilitating its assembly convenience.

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

[0076] In this embodiment, the lamp board 31 can be used to provide installation positions for the multiple light sources 32, so that the multiple light sources 32 can be installed on the lamp board 31, and then the lamp board 31 and the control board in the monitoring device 100 can be connected. At this time, it is not necessary to connect the multiple light sources 32 and the control board one by one, which is conducive to improving the convenience of electrical connection between the white light module 30 and the control board in the monitoring device 100. At the same time, in terms of mechanical connection, the multiple light sources 32 can also be installed on the lamp board 31 to form a whole, and then installed in the lower shell 12 at one time, thereby improving the convenience of installing multiple light sources 32 in the lower shell 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-light-transmitting material.

[0078] In this embodiment, the base 15 can also shield the lower shell 12, so as to better realize that the lower shell 12 emits light only in the preset light-emitting area. When the base 15 is extended into the receiving groove 121a of the bottom plate 121, the compactness of the distribution of the two can be improved, so as to reduce the overall volume of the monitoring device 100. In particular, when the lower shell 12 is rotatably connected to the base 15 around a vertical axis as described below, it is more convenient to set 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 be rotatable around a vertical horizontal axis, so that the camera module 20 can be rotated in a horizontal plane to adjust the shooting angle of the camera module 20 and improve the monitoring effect. Among them, 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 disposed in the first cavity 10a; the sound module 40 includes a frame 41 and a speaker 42 disposed on the frame 41, the frame 41, the speaker 42 and the bracket 13 enclose a rear sound cavity 40a, and a sound hole 11a is provided at the position of the upper shell 11 corresponding to the speaker 42.

[0082] In this embodiment, by setting up the sound module 40, it is convenient for the monitoring device 100 to play sounds and interact with the user by voice. Furthermore, the sound module 40 is set in the first cavity 10a, and the frame 41, speaker 42 and bracket 13 of the sound module 40 are enclosed to form the 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 volume of the 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, in order to improve the compactness of the distribution 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, the slot of the first slot 13a faces away from the lower shell 12; the camera module 20 is arranged in 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. In order 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 set to a spherical slot accordingly.
