[0022] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0024] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] An embodiment of the present application is a camera that can be used outdoors, and its specific structure is as Figures 1-4 shown.

[0026] As Figure 1 shown, the camera includes a housing 10, a lens 93 is fixed to the front end of the housing 10, and an antenna 92 and a wire harness 91 are provided at the rear end of the housing 10. Figure 1 The wire harness 91 in Figure 1 is used to transmit electric energy and data.

[0027] Combined with Figure 2 and Figure 3As shown in the figure, the camera further includes an imaging module 20, an elastic pressing block 15, and a buffer rubber sleeve 30. The two ends of the imaging module 20 are respectively a front lens 21 and a rear circuit board 22. The imaging module 20 is inserted into the buffer rubber sleeve 30 and is tightly wrapped by the buffer rubber sleeve 30. The side wall of the buffer rubber sleeve 30 is located between the imaging module 20 and the inner wall of the housing 10. The front end 31 of the buffer rubber sleeve 30 is clamped between the front lens 21 of the imaging module 20 and the lens 93. In the inner cavity at the rear end of the housing 10, a sealant is poured to form a sealant block 14. The sealant block 14 presses the rear circuit board 22 of the imaging module 20 through the elastic pressing block 15. Therefore, the entire imaging module 20 is fixed in the housing 10. And because the imaging module 20 is sleeved in the buffer rubber sleeve 30, it plays a role in buffering and shockproofing the imaging module 20 in all directions. Moreover, the assembly difficulty is relatively low, and it is more suitable for being installed inside a camera with a smaller volume. In specific implementation, the buffer rubber sleeve 30 can be made of silica gel, and the elastic pressing block 15 is made of a high-density sponge block, which can apply appropriate pressure to the imaging module 20 while not damaging the electronic components. The thickness of the elastic pressing block 15 should be slightly greater than the distance between the sealant block and the rear circuit board 22 of the imaging module 20.

[0028] In the embodiment, the imaging module 20 adopts a black light imaging module, which can capture color images in a dark environment. Therefore, the camera in the embodiment does not need to be provided with a fill light, which is beneficial to reducing the power consumption of the entire product.

[0029] In some embodiments, in combination with Figure 2 and Figure 3 As shown in the figure, the housing 10 includes a front shell 11 and a rear shell 12 that are fixedly connected to each other. The front shell 11 and the rear shell 12 can be fixedly connected by a plurality of screws. The front shell 11 and the rear shell 12 can be made of rust-proof and corrosion-proof materials, such as stainless steel / aluminum oxide alloy / zinc alloy, etc., to ensure the overall strength of the housing 10 while ensuring the rust-proof and corrosion-proof ability. A sealing ring 13 is clamped between the front shell 11 and the rear shell 12 so that the connection between the front shell 11 and the rear shell 12 can prevent dust and water. Among them, the imaging module 20 and the buffer rubber sleeve 30 are placed inside the front shell 11. The inner cavity at the rear end of the housing 10 is the inner cavity of the rear shell 12, that is, a sealant is poured into the inner cavity of the rear shell 12 to form a sealant block 14, and the sealant block 14 realizes the overall sealing of the rear shell 12.

[0030] In some embodiments, in combination with Figure 2 and Figure 3As shown in the figure, a circular mounting groove 111 is provided at the front end of the front housing 11. The lens 93 is fixed in the mounting groove 111. A sealing ring groove 112 concentric with the mounting groove 111 is provided on the surface of the mounting groove 111. Glue is poured into the sealing ring groove 112 to fix the lens 93 and achieve the sealing between the lens 93 and the mounting groove 111, ensuring the waterproof and dustproof performance at the front end of the front housing 10. The front end lens 21 of the camera module 20 is in interference fit with the front end 31 of the buffer rubber sleeve 30. A light-transmitting hole 311 corresponding to the front end lens 21 is provided at the front end 31 of the buffer rubber sleeve 30. The front end 31 of the buffer rubber sleeve 30 is exactly placed in the central hole 1111 of the mounting groove 111, and the front end surface of the buffer rubber sleeve 30 abuts against the lens 93, thereby fixing the position of the front end 31 of the buffer rubber sleeve 30 and the front end lens 21.

[0031] In some embodiments, as Figure 2 shown, the rear housing 12 is provided with an internal threaded hole 121. The wire harness 91 electrically connected to the camera module 20 passes through the internal threaded hole 121 of the rear housing 12. The wire harness 91 is used to transmit electric energy and data for the camera module 20. A nut 911 is screwed into the internal threaded hole 121, and the wire harness 91 passes through the nut 911. The nut 911 is used to fix part of the wire harness 91 on the rear housing 12, and the part of the wire harness 91 in the inner cavity of the rear housing 12 is fixed by a sealing rubber block 14.

[0032] In some embodiments, as Figure 2 shown, an antenna connector 921 is fixed on the wall of the rear housing 12, and the outer end of the antenna connector 921 is connected to the corresponding antenna 92. As Figure 1 shown, there are three antennas 92, so three antenna connectors 921 are correspondingly provided. The three antennas 92 can be allocated different functions as needed, such as 4G / 5G antennas, WIFI antennas, GPS / Beidou satellite positioning antennas, etc.

[0033] In some embodiments, as Figure 2 shown, two internal threaded holes 113 are opened below the outer wall of the front housing 11. The internal threaded holes 113 are used to connect external devices, such as mounting brackets, etc. The internal threaded holes 113 can also be provided above the outer wall of the front housing 11 to facilitate the hoisting of the camera.

[0034] In some embodiments, as Figure 2As shown, the camera module 20 has three mutually parallel circuit boards: the main camera circuit board 24, the POE power board 23, and the satellite / wireless communication circuit board 22'. Among them, the satellite / wireless communication circuit board 22' is the rear circuit board 22 and contacts the elastic pressing block 15. The POE power board 23 is located between the main camera circuit board 24 and the satellite / wireless communication circuit board 22'. The main camera circuit board 24 and the POE power board 23 are within the buffer rubber sleeve 30. The satellite / wireless communication circuit board 22' is provided with a SIM card slot (not shown), which allows the user to insert a SIM card. When in use, the rear shell 12 needs to be removed to expose the satellite / wireless communication circuit board 22', then the SIM card is inserted into the SIM card slot, and finally the rear shell 12 is fixedly installed on the front shell 11.

[0035] In some embodiments, as Figure 4 shown, each side of the inner wall of the front shell 11 is provided with 2 mutually parallel T-shaped inner ribs 115. The outer wall of the buffer rubber sleeve 30 closely adheres to the inner ribs 115, and the side wall of the buffer rubber sleeve 30 is clamped between the camera module 20 and the inner ribs 115.

[0036] As Figure 1 shown, the front end of the housing 10 is smaller, and the rear end of the housing 10 is larger, and the overall shape is similar to that of a bullet head. In other embodiments, as Figure 5 shown, the housing 10 of the camera can adopt a long cylindrical design with a square cross-section, and its internal structure is basically the same as that of the camera in the above embodiments. Or in other embodiments, the housing of the camera can also be made into a cylindrical structure with a circular cross-section.
