[0002] An action camera is a portable image recording device designed for sports, outdoor adventures, extreme activities, and other scenarios.

[0003] Chinese patent CN219392446U discloses a camera that, by providing a cavity, allows the camera to maintain its structure and volume without significantly increasing. A heat dissipation component or a battery component can be selectively installed in the cavity and connected to the camera for use. This can meet both the need for high heat generation caused by long-term use of the camera and the need for low heat generation caused by short-term use.

[0004] The above-mentioned device allows the battery or heat dissipation component to be detachably mounted on the camera. However, during the actual assembly process, although the heat dissipation component can be stably mounted on the camera through the relevant snap fasteners, the small size of the snap fasteners makes disassembly more inconvenient.

DETAILED DESCRIPTION

[0020] like Figures 1-10As shown, an active heat dissipation mechanism for an action camera includes a bracket 1 and a camera housing 4 disposed at the top of the bracket 1 and for mounting the action camera. The camera housing 4 is movably connected to the bracket 1, thereby enabling the action camera to be adjusted in angle relative to the bracket 1. When the action camera is live streaming or filming for a long time, the large amount of heat it generates may affect the filming or live streaming effect. To solve this problem, a heat sink 3 (using a fan to dissipate heat) is generally installed on the action camera to actively dissipate heat from the action camera. Based on this, the present solution has a circular hole on the camera housing 4 that cooperates with the heat sink 3. Of course, the circular hole is arranged opposite to the heat dissipation unit such as the heat dissipation fins on the action camera. A second orifice plate 10 is fixedly installed in the circular hole. In addition, a first orifice plate 8 is provided in the inner cavity of the circular hole and at a position outside the second orifice plate 10. The first orifice plate 8 is rotatably mounted in the circular hole and cooperates with the second orifice plate 10. In the initial state, the through hole of the first orifice plate 8 and the through hole of the second orifice plate 10 are staggered, thereby preventing external dust from entering the device.

[0021] A plurality of telescopic units 9 are fixedly provided on the outer peripheral wall of the first orifice plate 8, and a plug rod 2 that matches the telescopic unit 9 is fixedly provided on the radiator 3. Figure 2-Figure 5 As shown, the camera housing 4 is provided with a socket 7 that cooperates with the insertion rod 2, and the end of the telescopic unit 9 away from the first hole plate 8 extends into the socket 7, and a limiting component that cooperates with the telescopic unit 9 is provided on the outer peripheral wall of the insertion rod 2. During the installation of the radiator 3, it is only necessary to insert the insertion rod 2 into the socket 7. The limiting component can be used to lock the insertion rod 2 in the socket 7, thereby completing the installation of the radiator 3.

[0022] Reference Figure 8 As shown, the limiting assembly includes an arc-shaped groove 201 arranged on the outer peripheral wall of the insertion rod 2, and straight grooves 202 are also provided on the outer peripheral wall of the insertion rod 2 and at positions at both ends of the arc-shaped groove 201. Specifically, a limiting hole 203 that cooperates with the telescopic unit 9 is provided on the inner bottom surface of the upper straight groove 202. When the insertion rod 2 is inserted into the socket 7 so that the telescopic unit 9 is aligned with the limiting hole 203, the end of the telescopic unit 9 away from the first hole plate 8 can be inserted into the limiting hole 203, thereby locking the insertion rod 2 in the socket 7, and the first hole plate 8 also remains in a locked state, so that the first hole plate 8 is aligned with the through hole on the second hole plate 10. At this time, the radiator 3 can take out the heat generated by the motion camera during operation.

[0023] In order to quickly remove the radiator 3, the present invention has a push rod 13 slidably installed in the limiting hole 203, and the push rod 13 is elastically matched with the insertion rod 2. Furthermore, a baffle 12 is slidably provided at the top wall of the straight groove 202 above. Figures 8-10As shown, the bottom end of the blocking piece 12 is located near the upper side of the limiting hole 203, and a second inclined surface 1201 is provided on the outer side of the blocking piece 12 near the bottom end; Reference Figure 3-Figure 6 、 Figure 9 As shown, a pressure rod 5 is slidably assembled on the top of the insertion rod 2, and both sides of the bottom of the pressure rod 5 are set as extrusion surfaces 501 that cooperate with the push rod 13. The extrusion surface 501 is set at an angle. Specifically, a mounting hole that cooperates with the pressure rod 5 is opened at the top of the insertion rod 2. One end of the above-mentioned push rod 13 is in the limiting hole 203, and the other end extends into the mounting hole and contacts with the inclined extrusion surface 501.

[0024] In actual use, the multiple rods 2 on the radiator 3 are inserted into the sockets 7. Figure 8 As can be seen, a first inclined surface 2021 is provided on the inner wall of the lower straight groove 202 and at the bottom end thereof, so that when the insertion rod 2 is inserted into the interior of the insertion hole 7, the first inclined surface 2021 can squeeze the telescopic unit 9, so that the telescopic unit 9 can slide upward along the straight groove 202 into the arc-shaped groove 201. The cooperation between the telescopic unit 9 and the arc-shaped groove 201 can drive the first hole plate 8 to rotate, so that the first hole plate 8 and the through-holes on the second hole plate 10 are aligned, thereby facilitating the radiator 3 to quickly remove heat from the action camera. When the insertion rod 2 moves to a state where it is aligned with the limiting hole 203, one end of the telescopic unit 9 can be inserted into the limiting hole 203, thereby locking the insertion rod 2 in the insertion hole 7, and the first hole plate 8 will also be in a locked state. The plurality of pressure rods 5 are fixed together by the support frame 6. When the radiator 3 needs to be removed, the support frame 6 can be pressed downward to make the pressure rod 5 move downward relative to the insertion rod 2. During the downward movement of the pressure rod 5, the inclined extrusion surface 501 can squeeze the ejector rod 13, so that the ejector rod 13 moves outward along the limiting hole 203 and pushes out the telescopic unit 9 previously inserted into the limiting hole 203. As the pressure rod 5 moves downward to the limit position, it can drive the insertion rod 2 to move into the insertion hole 7. Figure 6As can be seen in the figure, a limit spring 11 is installed at the inner end surface of the socket 7. Therefore, the pressure rod 5 can compress the limit spring 11 when driving the plug rod 2 to move into the socket 7. As the plug rod 2 moves further into the socket 7, the telescopic unit 9 will move outward relative to the plug rod 2. When the telescopic unit 9 contacts the second inclined surface 1201 on the baffle 12, it can be squeezed, which is conducive to the end of the telescopic unit 9 moving to the outer side surface of the baffle 12 and in close contact with the baffle 12. When the support frame 6 is released, the pressure of the limit spring 11 can prompt the plug rod 2 to move outward, and the friction force of the telescopic unit 9 on the baffle 12 is used, so that in the process of the plug rod 2 moving outward, the baffle 12 can move relative to the plug rod 2 in the direction close to the limit hole 203 and finally cover the limit hole 203, and the telescopic unit 9 will also pass through the limit hole 203, so that the entire radiator 3 can be ejected smoothly.

[0025] To sum up, this device uses a limiting component to lock the insertion rod 2 and the first hole plate 8, so that the radiator 3 can be stably installed on the sports camera and actively dissipate heat. When disassembling, just press the support frame 6 to move one end of the telescopic unit 9 out of the limiting hole 203 and pass through the limiting hole 203 smoothly through the cooperation with the baffle 12, so that the radiator 3 can be quickly disassembled.

[0026] like Figures 1-10 As shown, a connecting ear plate is fixedly provided at the outer peripheral wall of the heat dissipation, and the above-mentioned plug rod 2 passes through the connecting ear plate and is fixedly connected thereto. A receiving groove 14 is provided on the camera housing 4 to cooperate with the telescopic unit 9. The receiving groove 14 is connected to the circular hole and the jack 7. The friction between the telescopic unit 9 and the side wall of the receiving groove 14 can maintain the stability of the first orifice plate 8. In addition, the friction between the first orifice plate 8 and the second orifice plate 10 can also ensure the stability of the first orifice plate 8. Figure 7 As shown, the telescopic unit 9 includes a rod sleeve 902 fixedly connected to the first hole plate 8, and a sliding rod 901 is slidably provided at one end of the rod sleeve 902 away from the first hole plate 8. A first spring is fixedly provided between the sliding rod 901 and the rod sleeve 902. Figure 7 As can be seen in the figure, one end of the sliding rod 901 passes through the receiving groove 14 and extends into the insertion hole 7, so that it can cooperate with the straight groove 202 and the arc groove 201 on the insertion rod 2.

[0027] Reference Figure 9 As shown, a positioning hole is provided on the inner end face of the mounting hole, and the cross section of the positioning hole is a T-shaped structure, and a T-shaped joint 502 is fixedly provided on the bottom end face of the pressure rod 5, and the joint 502 slides in the positioning hole to maintain a stable fit between the pressure rod 5 and the insertion rod 2. Figure 9As can be seen, the baffle 12 is an inverted L-shaped structure, and the top of the baffle 12 extends to the preset connection groove on the insertion rod 2. A second spring is provided between the bottom surface of the connection groove and the baffle 12 to achieve an elastic connection between the baffle 12 and the insertion rod 2. Figure 10 As shown, a strip groove is provided on the inner wall of the limiting hole 203, and a protrusion 1301 is fixedly provided on the push rod 13 to slide with the strip groove. A spring is provided between the protrusion 1301 and the end face of the strip groove. When the pressure rod 5 squeezes the push rod 13, the push rod 13 can compress the spring.
