[0002] Pan-tilt cameras, as important monitoring devices, are widely used in security, smart homes, and other fields. Currently, most common pan-tilt cameras on the market employ a combination of vertical and horizontal rotation, with their circuit boards mostly integrated into the vertical rotation module. Since the circuit board generates heat during operation, a large heatsink is usually required to ensure stable operation and meet heat dissipation needs. While the heatsink solves the heat dissipation problem to some extent, it also brings several drawbacks: it significantly increases the internal space required for the vertical rotation module, forcing a corresponding increase in the overall size of the device; at the same time, it makes the assembly process more complex and cumbersome, thus significantly increasing assembly costs and causing considerable inconvenience to product production and application.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Figure 1 shows an exploded view of a camera 100 according to an embodiment of the present invention, and Figure 2 shows an exploded view of a portion of the structure of a camera 100 according to an embodiment of the present invention. The following is a detailed description in conjunction with Figures 1 and 2.

[0032] As shown in Figures 1 and 2, the camera 100 may include a housing 110, a first bracket 120, and a second bracket 130. The housing 110 has an internal accommodating cavity 111 extending at least to one end of the housing 110 and forming an opening to facilitate the assembly of other components. For example, in the embodiment shown in Figure 1, the accommodating cavity 111 extends to both the left and right ends of the housing 110, forming openings at both ends. These openings can be closed by other components (e.g., by end caps, the second bracket, etc.).

[0033] One of the core functions of the first bracket 120 is to provide a connection, offering a stable foundation for other key components within the camera 100 (such as the second bracket 130, the drive unit 170, etc.), ensuring the stability of the camera 100 during movement (described in detail below). In addition, the first bracket 120 also has support and heat dissipation functions. Specifically, the first bracket 120 is installed in the accommodating cavity 111 and fixedly connected to the outer shell 110. A support surface 121 is provided on the outer periphery of the first bracket 120, which is in close contact with the inner wall of the outer shell 110, thus providing good support for the outer shell 110, giving the camera 100 good structural strength, and ensuring that there is little relative sway between the first bracket 120 and the outer shell 110. This close contact also ensures efficient heat transfer between the first bracket 120 and the outer shell 110. The second bracket 130 is disposed in the accommodating cavity 111 and fixedly connected to the first bracket 120. Multiple circuit boards (such as motherboard 140, communication circuit board 150, etc., detailed below) are provided on the second bracket 130. At least some of the circuit boards are provided with heat-conducting components (such as graphite foam 143, 152, etc., detailed below) between them and the first bracket 120 or the outer shell 110. These components can transfer the heat generated during the operation of the circuit boards to the first bracket 120 and the outer shell 110, and the first bracket 120 and the outer shell 110 can then act as heat dissipation components to cool the corresponding circuit boards.

[0034] According to one embodiment of the present invention, as shown in Figures 1 and 2, both the outer shell 110 and the first bracket 120 are metal structures; in other words, the outer shell 110 is a metal shell, and the first bracket 120 is a metal bracket. The use of metal structures for the outer shell 110 and the first bracket 120 enables more efficient heat conduction, further improving the heat dissipation efficiency of the camera 100.

[0035] According to one embodiment of the present invention, as shown in FIG1, one or more positioning bosses 112 are fixedly connected to the inner side of the housing 110, and the first bracket 120 abuts against these positioning bosses 112 and is screwed to these positioning bosses 112.

[0036] Figure 3 shows an exploded view of a portion of the structure of a camera 100 according to an embodiment of the present invention. As shown in Figures 2 and 3, the plurality of circuit boards may include a motherboard 140, on which a plurality of electronic components are integrated. The motherboard 140 may be fixed to one side (the upper side in Figure 2) of the second bracket 130 by screws, and the side on which the electronic components are integrated (or the side with more integrated electronic components, or the side with higher heat generation, hereinafter referred to as the outer side) faces away from the second bracket 130.

[0037] A first shielding cover 141 is provided on the outer side of the motherboard 140, covering at least a portion of the electronic components on the motherboard 140 to shield against electromagnetic interference. A first thermally conductive foil 142 is attached to the outer side of the first shielding cover 141, essentially covering the outer surface of the first shielding cover 141 and connected to the first bracket 120. The first thermally conductive foil 142, acting as a heat-conducting component connecting the motherboard 140 and the first bracket 120, can quickly conduct heat from the motherboard 140 to the first bracket 120, achieving efficient heat dissipation for the motherboard 140. The first thermally conductive foil 142 can be a metal foil such as copper foil or aluminum foil. Typically, the first thermally conductive foil 142 is selected with a higher thermal conductivity or heat dissipation efficiency than the first shielding cover 141 to significantly improve overall heat dissipation performance. For example, when the first shielding cover 141 is an aluminum shielding cover, copper foil with better thermal conductivity can be preferentially selected as the first thermally conductive foil 142.

[0038] A graphite foam 143 is disposed between the first thermally conductive foil 142 and the outer casing 110. In this case, the graphite foam 143 serves as a thermally conductive element connecting the motherboard 140 and the outer casing 110, rapidly transferring heat from the motherboard 140 to the outer casing 110, thereby further improving the heat dissipation efficiency of the motherboard 140. Those skilled in the art will readily understand that in some embodiments, only one of the first thermally conductive foil 142 and the graphite foam 143 may be used to achieve heat conduction to the first support 120 or the outer casing 110.

[0039] According to one embodiment of the present invention, as shown in FIG3, thermally conductive silicone, thermally conductive adhesive or graphite foam 144 is provided between the motherboard 140 and the first shielding cover 141, so that the heat generated by the motherboard 140 can be transferred to the first shielding cover 141 more quickly, thereby improving the heat dissipation efficiency of the camera 100.

[0040] According to one embodiment of the present invention, as shown in Figures 2 and 3, the multiple circuit boards may include a communication circuit board 150. The communication circuit board 150 is, for example, a circuit board that can realize communication functions such as WiFi, Zigbee, and Bluetooth, and integrates several electronic components. The communication circuit board 150 can be fixed to one side of the second bracket 130 (the right side in Figure 3) by screws, and the side with integrated electronic components (or the side with more integrated electronic components, or the side with higher heat generation, hereinafter referred to as the outer side) faces away from the second bracket 130.

[0041] A second shielding cover 151 is provided on the outside of the communication circuit board 150. The second shielding cover 151 covers at least a portion of the electronic components on the communication circuit board 150 (but does not cover the antenna) to shield against electromagnetic interference. Graphite foam 152 is provided between the second shielding cover 151 and the outer casing 110. This graphite foam 152 serves as a heat-conducting component connecting the communication circuit board 150 and the outer casing 110, and can quickly conduct heat from the communication circuit board 150 to the outer casing 110, thereby improving the heat dissipation efficiency of the communication circuit board 150.

[0042] A second thermally conductive foil 153 is attached to the outside of the second shielding cover 151, and the second thermally conductive foil 153 basically covers the outer surface of the second shielding cover 151. The second thermally conductive foil 153 can be a metal foil such as copper foil or aluminum foil. In practical applications, the second thermally conductive foil 153 needs to be selected with a higher thermal conductivity or heat dissipation efficiency than the second shielding cover 151 to improve the ability of the second shielding cover 151 to dissipate heat to the surrounding environment (e.g., air). For example, when the second shielding cover 151 is an aluminum shielding cover, copper foil with better thermal conductivity can be preferentially selected as the second thermally conductive foil 153.

[0043] According to one embodiment of the present invention, as shown in FIG3, thermally conductive silicone, thermally conductive adhesive or graphite foam 154 is provided between the communication circuit board 150 and the second shielding cover 151, so that the heat generated by the communication circuit board 150 can be transferred to the second shielding cover 151 more quickly, thereby improving the heat dissipation efficiency of the camera 100.

[0044] Figure 4 shows an exploded view of a portion of the structure of a camera 100 according to an embodiment of the present invention. As shown in Figures 2 and 4, the multiple circuit boards may include an image sensor circuit board 160, on which electronic components such as an image sensor are integrated. The image sensor circuit board 160 can be fixed to one side of the second bracket 130 by screws. Thermally conductive silicone, thermally conductive adhesive, or graphite foam 161 is disposed between the image sensor circuit board 160 and the first bracket 120. This thermally conductive silicone, thermally conductive adhesive, or graphite foam 161 serves as a heat-conducting component connecting the image sensor circuit board 160 and the first bracket 120, which can quickly conduct heat from the image sensor circuit board 160 to the first bracket 120, improving the heat dissipation efficiency of the image sensor circuit board 160. Preferably, the camera 100 also includes a lens, which is mounted on the second bracket 130 and aligned with the image sensor.

[0045] According to one embodiment of the present invention, as shown in FIG1, the camera 100 may further include a driving device 170. The output portion of the driving device 170 is fixedly connected to the first bracket 120 and configured to drive the first bracket 120 to rotate around a first axis and / or a second axis, thereby adjusting the shooting direction of the camera 100. The first axis may be, for example, a horizontal axis, and by driving the first bracket 120 to rotate around the first axis, the shooting direction of the camera 100 can be adjusted up and down. The second axis may be, for example, a vertical axis, and by driving the first bracket 120 to rotate around the second axis, the shooting direction of the camera 100 can be adjusted left and right.

[0046] According to one embodiment of the present invention, as shown in FIG2, the first bracket 120 may include a first structural portion 122, a second structural portion 123, and a third structural portion 124. The first structural portion 122 is generally flat, and the thermally conductive silicone, thermally conductive adhesive, or graphite foam 161 mentioned above is disposed between the image sensor circuit board 160 and the first structural portion 122. The second structural portion 123 is connected to the front side of the first structural portion 122 (the side closer to the second bracket 130 in FIG2). The second structural portion 123 is generally arc-shaped and, together with the first structural portion 122, forms a semi-enclosed lens mounting cavity, which can accommodate and protect the lens and related components. The third structural portion 124 is connected to the rear side of the first structural portion 122. The third structural portion 124 is composed of a plurality of fixing posts and stiffeners perpendicular to the first structural portion, and defines a semi-enclosed drive device mounting cavity, which can accommodate part of the drive device. The support surface 121 mentioned above can be disposed on the outside of the first structural part 122, the second structural part 123 and / or the third structural part 124.

[0047] According to one embodiment of the present invention, as shown in FIG2, the second bracket 130 may include a cover plate portion 131 and a connecting portion 132. The cover plate portion 131 is generally flat and can close the opening at the front end of the housing 110. In addition, a lens hole is provided at the center of the cover plate portion 131 for supporting and fixing the lens. The connecting portion 132 is disposed on the rear side of the cover plate portion 131. The connecting portion 132 is composed of a plurality of connecting posts perpendicular to the cover plate portion 131. These connecting posts can be used to connect the first bracket 120, the main board 140, the communication circuit board 150, the image sensor circuit board 160, etc. Preferably, when the first bracket 120 and the second bracket 130 are connected together, the second structural portion 123 of the first bracket 120 abuts against the cover plate portion 131 of the second bracket 130.

[0048] Compared with the prior art, the embodiments of this utility model provide a camera 100. By providing a heat-conducting component between the circuit board and the first bracket 120 or the housing 110, the heat generated during the operation of the circuit board can be transferred to the first bracket 120 and the housing 110, which then act as heat sinks to dissipate heat from the corresponding circuit board. This not only eliminates the need for an additional heat sink but also improves heat dissipation efficiency, saves internal space, simplifies assembly processes, and facilitates the miniaturization of the camera 100.
