Description

Technical Field

[0001] This utility model relates to the field of parking lot technology, and in particular to a bullet-type surveillance camera with high heat dissipation. Background Technology

[0002] Due to security requirements, parking lots currently need to deploy surveillance networks, specifically by installing surveillance cameras throughout the parking lot. For cost reasons, the surveillance cameras used in parking lots are primarily bullet cameras. For outdoor parking lots, bullet cameras must withstand sun and rain, operating in harsh environments. Especially in summer, outdoor temperatures are high, and for waterproofing and dustproofing purposes, the camera components are all built into sealed housings. This makes the camera components prone to image distortion and overheating protection issues due to the high temperatures.

[0003] Therefore, there is a need to develop a new type of bullet-type surveillance camera that can improve heat dissipation efficiency and reduce the risk of image distortion and overheating protection when working outdoors. Utility Model Content

[0004] Based on this, the present invention provides a bullet-type surveillance camera with high-efficiency heat dissipation. It uses a heat transfer plate and a bottom shell to form an inner cavity for housing the camera component. The first heat-conducting plate, the second heat-conducting plate, and the heat transfer plate are used as heat transfer mediums to transfer the heat generated by the camera component during operation to the heat dissipation fin assembly. The heat dissipation fin assembly dissipates the heat to the external environment, improving heat dissipation efficiency and reducing the risk of image distortion and overheating protection when working outdoors.

[0005] A bullet-type surveillance camera with high-efficiency heat dissipation, comprising:

[0006] support;

[0007] A monitoring module mounted on a bracket; the monitoring module includes: a base shell connected to the bracket, a camera assembly connected to the base shell, a heat transfer plate connected to the base shell, a heat dissipation fin assembly connected to the heat transfer plate, and a rain cover connected to the base shell; the front end of the base shell is provided with a recess for accommodating the camera assembly; the camera assembly includes: a protective cover, a first heat-conducting plate, a camera circuit board, and a second heat-conducting plate connected in sequence; the protective cover protrudes to the front of the base shell through the recess; the first and second heat-conducting plates are both U-shaped heat-conducting plates and are attached to the outer periphery of the camera circuit board. A U-shaped groove is formed between the first and second heat-conducting plates, and the bottom and sides of the camera assembly are snapped onto the bottom shell through the groove; the camera circuit board is equipped with a camera, and the camera protrudes from the first heat-conducting plate into the protective cover; the heat transfer plate is a Z-shaped heat-conducting plate, and the heat transfer plate and the bottom shell are combined to form an inner cavity; the front end of the heat transfer plate is equipped with a tongue that docks with the top of the camera assembly, and the tongue is inserted into the groove from top to bottom; the heat dissipation fin group is located at the rear end of the heat transfer plate; the rain cover is placed on the front end of the heat transfer plate and the bottom shell from top to bottom.

[0008] The aforementioned high-efficiency heat dissipation bullet camera features a monitoring module whose bottom shell and thermal adapter plate form an internal cavity for housing the camera assembly. When the camera circuit board in the camera assembly operates, the heat it generates is dissipated through two pathways: firstly, it is transferred to the thermal adapter plate via the first and second heat-conducting plates, and then to the heat dissipation fin assembly, from which it is dissipated into the external environment; secondly, it is dissipated into the internal cavity, then transferred to the thermal adapter plate via the air within the cavity, and then to the heat dissipation fin assembly, from which it is dissipated into the external environment. Therefore, the heat generated by the camera circuit board is mainly transferred to the heat dissipation fin assembly through the thermal adapter plate to dissipate into the external environment, thus improving heat dissipation efficiency while ensuring the airtightness of the camera circuit board's operating environment. The above design utilizes a heat transfer plate and a bottom shell to form an internal cavity for housing the camera component. The first heat-conducting plate, the second heat-conducting plate, and the heat transfer plate serve as heat transfer media to transfer the heat generated by the camera component during operation to the heat dissipation fin assembly. The heat dissipation fin assembly then dissipates the heat to the external environment, improving heat dissipation efficiency and reducing the risk of image distortion and overheating protection during outdoor operation.

[0009] In one embodiment, the heat transfer plate has a stepped portion around its periphery, which abuts against the periphery of the top of the bottom shell to form a sealing structure. The stepped portion can improve the sealing performance at the connection between the heat transfer plate and the bottom shell.

[0010] In one embodiment, the bottom shell, heat transfer plate, heat dissipation fin assembly, and rain cover are connected together by a first screw, resulting in a simple structure and easy disassembly.

[0011] In one embodiment, the protective cover, the first heat-conducting plate, the camera circuit board, and the second heat-conducting plate are connected together by a second screw, which is an insulated screw, so as to achieve simple connection and easy disassembly while ensuring electrical insulation.

[0012] In one embodiment, the surfaces of the first heat-conducting plate, the second heat-conducting plate, and the tongue are all provided with insulating varnish or insulating film. The insulating varnish or insulating film can prevent short circuits between the first heat-conducting plate, the second heat-conducting plate, and the tongue and the electronic components on the camera circuit board.

[0013] In one embodiment, the first heat-conducting plate, the second heat-conducting plate, and the heat transfer plate are all one of a heat spreader plate, a copper plate, or an aluminum alloy plate.

[0014] In one embodiment, the back of the protective cover has a groove for receiving the first heat-conducting plate. The groove allows the first heat-conducting plate to be embedded in the rear end of the protective cover, so that the protective cover also covers the first heat-conducting plate, improving the sealing performance.

[0037] like Figures 1 to 12 As shown, this is a bullet-type surveillance camera 100 with high-efficiency heat dissipation, which is an embodiment of the present invention.

[0038] like Figure 1 and Figure 2As shown, the high-efficiency heat dissipation bullet camera 100 includes a bracket 10 and a monitoring module 20 mounted on the bracket 10. The bracket 10 supports the monitoring module 20, providing a stable working platform, and is typically mounted on a light pole, wall, or fence. The monitoring module 20 is used to implement scene monitoring functions and can generally be connected to the control console in the monitoring room via wireless or wired means.

[0039] The following text, combined with Figures 1 to 12 The above-mentioned high-efficiency heat dissipation bullet camera 100 will be further explained.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the support 10 is a multi-axis adjustable structure, which can achieve manual planar rotation or vertical rotation, for example. In other embodiments, the support 10 can also be an electrically controlled multi-axis rotating structure, with attitude control achieved by connecting to a control console in the monitoring room.

[0041] like Figures 3 to 6 As shown, the monitoring module 20 includes: a base shell 21 connecting to the bracket 10, a camera assembly 22 connected to the base shell 21, a heat transfer plate 23 connected to the base shell 21, a heat dissipation fin assembly 24 connected to the heat transfer plate 23, and a rain cover 25 connected to the base shell 21. The base shell 21 and the heat transfer plate 23 together form a structure for supporting the camera assembly 22; that is, the heat transfer plate 23 is equivalent to a top cover matching the base shell 21. Simultaneously, the heat transfer plate 23 serves a heat transfer function, transferring heat to the heat dissipation fin assembly 24. The heat dissipation fin assembly 24 is located outside the base shell 21 and is exposed to the external environment, allowing heat to dissipate. The rain cover 25 is used to shield the camera assembly 22 from rain, preventing rainwater from directly impacting the camera assembly 22 during rainy weather.

[0042] like Figure 5 As shown, in this embodiment, the bottom shell 21, heat transfer plate 23, heat dissipation fin assembly 24, and rain cover 25 are connected together by the first screw 26, resulting in a simple structure and easy disassembly. Furthermore, combined with... Figure 4 , Figure 5 ,as well as Figure 7 As shown, in this embodiment, the bottom shell 21 is provided with a protruding post 211 extending from bottom to top. The protruding post 211 is provided with a screw hole. During assembly, the protruding post 211 passes through the heat transfer plate 23, the heat dissipation fin assembly 24 and the rain cover 25 from bottom to top. The first screw 26 is connected to the screw hole of the protruding post 211. The rain cover 25, the heat dissipation fin assembly 24 and the heat transfer plate 23 are pressed onto the bottom shell 21 by the first screw 26.

[0043] like Figure 7As shown, the front end of the bottom shell 21 is provided with a recess 212 for accommodating the camera assembly 22. The recess 212 is a slot structure opened at the front end of the bottom shell 21, and the camera assembly 22 can slide into the recess 212 from top to bottom.

[0044] like Figures 8 to 10 As shown, the camera assembly 22 includes a protective cover 221, a first heat-conducting plate 222, a camera circuit board 223, and a second heat-conducting plate 224 connected in sequence. The protective cover 221 protrudes to the front of the bottom shell 21 through a recessed groove 212. Both the first heat-conducting plate 222 and the second heat-conducting plate 224 are U-shaped heat-conducting plates and are attached to the outer periphery of the camera circuit board 223. A U-shaped sliding groove is formed between the first heat-conducting plate 222 and the second heat-conducting plate 224, and the bottom and sides of the camera assembly 22 are engaged with the bottom shell 21 through the sliding groove. The camera circuit board 223 is equipped with a camera, and the camera protrudes from the first heat-conducting plate 222 into the protective cover 221.

[0045] In addition, such as Figure 5 and Figure 6 As shown, in this embodiment, the monitoring module 20 further includes a data cable 27 for connecting the camera assembly 22. One end of the data cable 27 is connected to the camera circuit board 223, and the other end extends to the bottom of the rear end of the base 21. Meanwhile, the bottom of the rear end of the base 21 is provided with a matching recess 213.

[0046] To facilitate disassembly and assembly, in this embodiment, the protective cover 221, the first heat-conducting plate 222, the camera circuit board 223, and the second heat-conducting plate 224 are connected together by a second screw 225, and the second screw 225 is an insulating screw (e.g., a screw made of PVC material). This ensures electrical insulation while achieving a simple connection and easy disassembly.

[0047] like Figure 11 As shown, in this embodiment, the back of the protective cover 221 is provided with a groove 2211 for receiving the first heat-conducting plate 222. The groove 2211 allows the first heat-conducting plate 222 to be embedded in the rear end of the protective cover 221, so that the protective cover 221 also covers the first heat-conducting plate 222, improving sealing. For example, in this embodiment, the depth of the groove 2211 is equal to the thickness of the first heat-conducting plate 222, so that when the first heat-conducting plate 222 is combined with the protective cover 221, the first heat-conducting plate 222 fits perfectly into the groove 2211.

[0048] like Figure 12 As shown, the heat transfer plate 23 is a Z-shaped heat-conducting plate, and the heat transfer plate 23 is combined with the bottom shell 21 to form an inner cavity. The front end of the heat transfer plate 23 is provided with a tongue 231 for docking with the top of the camera assembly 22, and the tongue 231 is inserted into the sliding groove from top to bottom. The heat dissipation fin assembly 24 is located at the rear end of the heat transfer plate 23.

[0049] like Figures 3 to 5 As shown, the rain cover 25 is installed from top to bottom over the front end of the heat transfer plate 23 and the bottom shell 21.

[0050] Furthermore, such as Figure 12 As shown, in this embodiment, the periphery of the heat transfer plate 23 is provided with a stepped portion 232, which abuts against the periphery of the top of the bottom shell 21 to form a sealing structure. The stepped portion 232 can improve the sealing performance at the connection between the heat transfer plate 23 and the bottom shell 21. In addition, in some embodiments, a sealing ring may also be provided at the connection between the heat transfer plate 23 and the bottom shell 21.

[0051] In this embodiment, the surfaces of the first heat-conducting plate 222, the second heat-conducting plate 224, and the tongue 231 are all provided with insulating varnish or insulating film. The insulating varnish or insulating film can prevent short circuits between the first heat-conducting plate 222, the second heat-conducting plate 224, and the tongue 231 and the electronic components on the camera circuit board 223.

[0052] In addition, in this embodiment, the first heat-conducting plate 222, the second heat-conducting plate 224, and the heat transfer plate 23 are all aluminum alloy plates. In other embodiments, the first heat-conducting plate 222, the second heat-conducting plate 224, and the heat transfer plate 23 can also be heat spreaders or copper plates.

[0053] Brief description of working principle:

[0054] like Figure 5 As shown, the bottom shell 21 of the monitoring module 20 and the heat transfer plate 23 form an internal cavity for housing the camera assembly 22. When the camera circuit board 223 in the camera assembly 22 is working, the heat it generates is dissipated in two ways:

[0055] One method is to transfer heat to the heat transfer plate 23 through the first heat-conducting plate 222 and the second heat-conducting plate 224, and then to the heat dissipation fin assembly 24 through the heat transfer plate 23, and finally to the external environment through the heat dissipation fin assembly 24.

[0056] Secondly, the heat is dissipated into the inner cavity, and then transferred to the heat transfer plate 23 via the air in the inner cavity. It is then transferred to the heat dissipation fin assembly 24 via the heat transfer plate 23, and finally dissipated into the external environment via the heat dissipation fin assembly 24.

[0057] Therefore, the heat generated by the camera circuit board 223 is mainly transferred to the heat sink fin assembly 24 through the heat transfer plate 23 to dissipate into the external environment, thereby improving heat dissipation efficiency while ensuring the airtightness of the working environment of the camera circuit board 223.

[0058] The aforementioned high-efficiency heat dissipation bullet camera 100 utilizes a heat transfer plate 23 and a bottom shell 21 to form an internal cavity for housing the camera assembly 22. The first heat-conducting plate 222, the second heat-conducting plate 224, and the heat transfer plate 23 serve as heat transfer media to transfer the heat generated by the camera assembly 22 during operation to the heat dissipation fin assembly 24. The heat is then dissipated to the external environment through the heat dissipation fin assembly 24, thereby improving heat dissipation efficiency and reducing the risk of image distortion and overheating protection during outdoor operation.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
