[0002] With the progress of society and the improvement of living standards, people hope that the bulb can have multiple functions, and the demand for indoor and outdoor monitoring cameras is increasing. At present, the bulb sold on the market mostly only has simple lighting function. The prior art mechanically combines the bulb with the monitoring camera, which can only be cumbersome and has poor practicability, and has no waterproof function, and is easily damaged when installed outdoors and rained on. These problems limit the application scenarios of the bulb camera. In order to expand the monitoring range, the monitoring camera on the market is equipped with a horizontal drive motor and a vertical drive motor to realize the rotation of the camera ball head in each direction. Specifically, an installation cover is added, the camera ball head is connected to the installation cover through the vertical drive motor, and the installation cover is driven to rotate horizontally by the horizontal drive motor. During assembly, there is a matching gap between the drive shafts of the two motors and the installation cover, which results in poor waterproof performance. In addition, due to the rotating characteristics of the drive shaft itself, the drive shaft and the installation cover are usually interference-fitted to ensure their close connection, which causes deformation of the installation cover during disassembly. Not only is the installation cover easily damaged, but also when one of the drive shafts is disassembled, the other drive shaft and the installation cover may also be loose, shifted, etc., which reduces the waterproof performance and causes the rotation direction of the camera ball head to deviate, affecting the actual use experience.

[0055] The emergence of the bulb camera facilitates the integration of monitoring functions in the existing bulb installation position. For users with monitoring needs, no additional installation steps are required during actual installation. After the bulb is installed, the monitoring function can be turned on at the same time, which is convenient to operate. The bulb camera in the prior art simply combines the bulb and the monitoring camera. The actual size is large and appears bulky. At the same time, the practicability is poor. Since no waterproof function is considered, it is easy to be damaged by rain when used for outdoor monitoring.

[0056] Based on the above problems, it is necessary to provide a bulb camera with lighting and monitoring functions and waterproof.

[0057] As shown in Figure 1 The bulb camera provided by the present application is composed of a lighting assembly 10, a cover assembly 20 installed at the lower part of the lighting assembly 10, and a camera assembly 30 installed in the cover assembly 20. The upper part of the lighting assembly 10 has a threaded plug commonly used with bulbs on the market. In this way, the bulb camera provided by the present application can be directly installed on the same size lamp holder.

[0058] As shown in Figure 2 The lighting assembly 10 is composed of a light-transmitting lamp cylinder 11, a lamp holder 12, a lamp holder 13, a light-emitting part 14, a control panel 15, and a positioning bracket 16. The lamp holder 12 and the lamp holder 13 cover the top and bottom of the light-transmitting lamp cylinder 11, respectively. The upper end of the positioning bracket 16 is connected to the light-transmitting lamp cylinder 11, and the lower end is connected to the lamp holder 13. The control panel 15 is installed on the positioning bracket 16, and the light-emitting part 14 is installed on the lamp holder 13.

[0059] Considering the risk of water entering the bulb camera in outdoor use scenarios, as shown in Figure 1 , Figure 2 and Figure 8As shown in FIG. 1, the cover body in the cover assembly 20 includes an upper cover 21 and a lower cover 22, and the installation cavity 201 formed by the upper cover 21 and the lower cover 22 can sufficiently include the camera assembly 30. The cover assembly 20 only retains a view window 202 of the up-down rotation range of the camera assembly 30, so as to reduce the rainwater splashing on the camera assembly 30 as much as possible. The view window 202 extends to the bottom of the camera assembly 30, which can ensure that the shooting field of view can cover the field below the bulb camera, avoid the appearance of the visual blind area, and facilitate drainage and avoid the rainwater remaining in the cover assembly.

[0060] Please further refer to Figure 2 、 Figure 7 and Figure 11 , in order to realize the rotation shooting of the camera assembly 30 and obtain a larger shooting field of view, the bulb camera provided by the application includes a first driving member 50 fixedly connected to the lighting assembly 10 and a second driving member 60 fixedly connected to the camera assembly 30. The first driving shaft 52 of the first driving member 50 is fixedly connected to the cover assembly 20 and arranged vertically, and the second driving shaft 62 of the second driving member 60 is fixedly connected to the cover assembly 20 and arranged horizontally. Under the driving of the first driving motor 51 and the second driving motor 61, the camera assembly 30 can rotate upwards or downwards in the cover assembly 20, and the cover assembly 20 can rotate horizontally relative to the lighting assembly 10, thereby driving the camera assembly 30 to rotate horizontally.

[0061] Since the lighting assembly 10 and the cover assembly 20 are connected through the first driving shaft 52 of the first driving member 50, in an outdoor scene, water vapor is easy to enter the lighting assembly from the connection between the first driving shaft 52 and the cover assembly 20. The rainwater remaining on the outer surface of the camera assembly 30 also reaches the connection and penetrates into the interior of the lighting assembly 10 with the rotation of the camera assembly 30. After long-term use, condensate water will accumulate in the lighting assembly 10, which has the risk of circuit short circuit.

[0062] Based on this, please refer to Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 The bulb camera provided by the application further includes a sealing connecting member 40 connected to the first driving member 50 and the upper cover 21 in the cover assembly 20, as shown in FIG. 2. The sealing connecting member 40 has a connecting portion 401 and a sealing portion 402. The connecting portion 401 is provided through the mounting hole 203 of the upper cover 21 and connected to the first driving shaft 52 in the first driving member 50 from the sealing portion 402, as shown in FIG. 3. Specifically, as shown in FIG. 4, the sealing portion 402 of the sealing connecting member 40 is provided with a sealing groove 4021, and the first driving shaft 52 in the first driving member 50 is provided with a sealing ring 521. The sealing ring 521 is arranged in the sealing groove 4021, so as to prevent water vapor from entering the lighting assembly 10 from the connection between the first driving shaft 52 and the cover assembly 20. Figure 5 Figure 3 Figure 7 Figure 6 ​​​As shown in the figures, in this embodiment provided by the present application, the sealing connector 40 comprises a fastening bolt 41 and a sealing gasket 42, wherein the fastening bolt 41 comprises a bolt body 411 and a gasket 412, the sealing gasket 42 has an inner hole 403 for the bolt body 411 to pass through; the screw part of the bolt body 411 is the connecting part 401, and the nut part of the bolt body 411, the gasket 412 and the sealing gasket 42 together constitute the sealing part 402; it can be understood that in other embodiments, the gasket 412 can also be integrally connected to the bolt body 411, as long as it can cover the inner hole of the sealing gasket 42. As shown in Figure 8 、 Figure 9 and Figure 10 , after the actual assembly is completed, the sealing part 402 of the sealing connector 40 can block the mounting hole 203 of the outer cover assembly 20, the sealing gasket 42 is sleeved on the first driving shaft 52, the bolt body 411 is screwed with the first driving shaft 52, and the gasket 412 and the nut of the bolt body 411 together block the inner hole of the sealing gasket 42, so as to avoid water vapor or capillary water from entering the lighting assembly 10 and avoid the accumulation of condensed water inside the lighting assembly 10. Optionally, the sealing gasket 42 is made of silica gel and is in interference fit with the first driving shaft 52, so that the sealing gasket 42 can be firmly sleeved on the first driving shaft 52, further ensuring the waterproof performance at the sealing connector 40.

[0063] As shown in Figure 3 、 Figure 6 and Figure 7 , in order to ensure the reliability of the connection between the first driving member 50 and the upper cover body 21, the mounting hole 203 on the upper cover body 21 and the first driving shaft 52 are all in the shape of a waist and match with each other, and the inner hole of the sealing gasket 42 is also in the shape of a waist that matches the shape of the first driving shaft 52.

[0064] Optionally, as shown in Figure 3 and Figure 10 , the outer cover assembly 20 has a mounting groove 205 arranged in the mounting cavity 201 and surrounding the mounting hole 203, and a boss structure 204 is formed on the top of the upper cover body 21 and protrudes upward, and the sealing connector 40 is accommodated in the mounting groove 205 to avoid the camera assembly 30 in the mounting cavity 201. As shown in Figure 15 , the lamp holder 13 has an alignment hole 1302 for accommodating the boss structure 204.

[0065] Further, considering that the assembly gap between the outer cover assembly 20 and the lighting assembly 10 also easily causes rainwater to enter, the surface of the lamp holder 13 also has a first silica gel sealing area that abuts against the light-transmitting lamp barrel 11 and a second silica gel sealing area that abuts against the outer cover assembly 20, and the two silica gel sealing areas can be silica gel sealing rings fixedly connected to the lamp holder 13 or silica gel coatings coated on the surface of the lamp holder 13, as long as the waterproof performance can be ensured.

[0066] As shown in Figure 2 , Figure 11 and Figure 12 , the camera assembly 30 is composed of a shell 31, a lens module 32, an infrared light supplement module 33, and a sealing plug 34. The shell 31 is composed of a front shell body 311 and a rear shell body 312 and is connected by bolts. The infrared light supplement module 33 and the lens module 32 are both mounted on the front shell body 311 by bolts, and the second driving member 60 is mounted on the rear shell body 312. A sealing ring can be arranged between the front shell body 311 and the rear shell body 312 to ensure the waterproof performance of the shell 31. The sealing plug 34 is mainly used to block the external interface of the camera assembly 30, which can be used for but not limited to devices such as external SD card, USB interface, and Micro-USB interface.

[0067] Further, as shown in Figure 13 , the lens module 32 specifically includes a main circuit board 321, a lens body 322, an indicator light 323, and a heat dissipation bracket 324. The lens body 322 and the indicator light 323 are mounted on the main circuit board 321, and the main circuit board 321 is fixedly connected to the heat dissipation bracket 324. The heat dissipation bracket 324 is connected to the front shell body 311 by bolts to fix the lens module 32 in the shell 31. The infrared light supplement module 33 includes an infrared light supplement circuit board 331 mounted on the front shell body 311 and a plurality of infrared lamp beads 332 mounted on the infrared light supplement circuit board 331. The infrared lamp beads 332 are lit when the light intensity is weak to increase the infrared light supplement.

[0068] Further, as shown in Figure 11 and Figure 12 , the front shell body 311 has a light transmission area corresponding to the infrared light supplement module 33. The light transmission area is specifically a light transmission cover 313. The light transmission cover 313 is also provided with a microphone hole, a lens mounting hole, and an indicator light mounting hole.

[0069] Please refer to Figure 4 and Figure 11 , in order to ensure the reliability of the connection between the camera assembly 30 and the cover assembly 20, the cover assembly 20 further includes a bracket plate 23 fixed in the upper cover body 21 and a screw column 24 extending from top to bottom. The bottom of the bracket plate 23 is provided with a clamping groove 2301, Figure 11The second drive shaft 62 shown is also oblong, and has bolt holes 6201 along the radial direction that match the threaded holes of the screw post 24. The second drive shaft 62 is engaged in the engagement groove 2301 and fixedly connected to the screw post 24 by bolts. The bracket plate 23 is specifically composed of a pair of plates 231 arranged opposite to each other on both sides of the screw post 24 to form the aforementioned engagement groove 2301. The two plates are also connected to the screw post 24 to increase the connection rigidity between the screw post 24 and the upper cover 21. In other words, in this embodiment, the screw post 24 can also be regarded as being embedded in the bracket plate 23, and the bracket plate 23 has a notch at the bottom for the screw to enter. It is understood that since the second drive shaft 62 is mainly connected and fixed to the upper cover 21 through the screw post 24, the upper cover 21 will not deform during the assembly and disassembly process, thus not affecting the assembly between the first drive shaft 52 and the upper cover 21, thereby indirectly improving the waterproof performance of the entire bulb camera. It is understandable that in other embodiments, if only the guiding and supporting role of the snap-fit ​​groove 2301 on the bracket plate 23 on the second drive shaft 62 is considered, the bracket plate 23 and the screw post 24 can be arranged at intervals in the extension direction of the second drive shaft 62, as long as it does not affect the camera assembly 30 being installed into the mounting cavity 201.

[0070] Furthermore, such as Figure 9 and Figure 12 As shown, in order to maintain the vertical rotation balance of the camera assembly 30, a bearing (not shown) can also be provided between the side of the outer shell 31 away from the second drive shaft 62 and the upper cover 21. Specifically, the upper cover 21 is provided with a first bearing mounting hole 2102, and the outer shell 31 is provided with a second bearing mounting hole 3101 corresponding to the first bearing mounting hole 2102.

[0071] To ensure the stability of the power supply line for the camera assembly 30, in this embodiment provided in this application, the lighting assembly 10 and the camera assembly 30 are connected by a cable to achieve power supply and signal transmission. For example... Figure 15 As shown, the lamp holder 13 also has a first wire hole 1301, such as Figure 3 As shown, the upper cover 21 of the outer cover assembly 20 has an arc-shaped second wire passage hole 2101, as... Figure 12 As shown, a third wire hole 302 is provided on the rear housing 312 of the camera assembly 30. It can be understood that waterproof filler is provided at the first wire hole 1301, the second wire hole 2101 and the third wire hole 302 to ensure the waterproof performance of the lighting assembly 10 and the camera assembly 30.

[0072] like Figure 2As shown, the light-transmitting tube 11 includes a light-transmitting tube body 111 and a light shield 112.
