[0051] A dashcam is a type of video recording device. Internally, a dashcam contains circuit boards and other components. Currently, dashcams only dissipate heat from the internal circuit boards by using ventilation holes in the casing. This method is ineffective for high-power circuit boards.
[0052] This utility model proposes a camera device.
[0053] Please see Figure 1 , Figure 2 In one embodiment of this utility model, the camera device includes a housing 100, an electronic control unit 200, a first heat sink 300, and a camera. The housing 100 has a mounting cavity 130, and it should be noted that the housing 100 also has heat dissipation holes. Further, the first heat sink 300 is fixed in the mounting cavity 130, and the electronic control unit 200 is mounted in the mounting cavity 130 through the first heat sink 300. It should be noted that the first heat sink 300 is made of a material with good thermal conductivity, such as aluminum. It can be understood that the electronic control unit 200 is mounted in the mounting cavity 130 through the first heat sink 300. That is to say, the first heat sink 300 in this application serves both to mount the electronic control unit 200 and to dissipate heat from the electronic control unit 200. Thus, the first heat sink 300, together with the heat dissipation holes, can further improve the heat dissipation effect in the camera device, thereby solving the problem of poor heat dissipation in existing dashcams. Furthermore, in some embodiments, the camera is electrically connected to the electronic control unit 200, wherein the electronic control unit 200 includes a substrate and a plurality of electrical components mounted on the substrate, wherein the substrate is a PCB board, and the electronic control unit 200 can be a single board structure or a multi-board structure.
[0054] In one embodiment, reference Figure 2The electronic control unit 200 includes a first electronic control board 210 and a second electronic control board 220. The first electronic control board 210 is used for storing video, and the second electronic control board 220 is used for communication. Further, in some embodiments, the first electronic control board 210 includes a first board body and a storage module, and the second electronic control board 220 includes a second board body and a communication module. The video recorded by the camera can be stored in the storage module. Further, when a user needs to obtain the video in the first electronic control board 210, they can connect to the camera device through the communication module in the second electronic control board 220 to obtain the video in the first electronic control board 210.
[0055] Further, refer to Figure 2 , Figure 3 , Figure 4 The mounting cavity 130 is provided with support columns 170, wherein multiple support columns 170 can be provided and are spaced apart. The first electronic control board 210 is provided at the bottom of the first heat sink 300, and the second electronic control board 220 is provided at the top of the first heat sink 300. The first heat sink 300 is fixed to the support columns 170, which allows the first heat sink 300 and the support columns 170 to clamp the second electronic control board 220. It should be noted that when the second electronic control board 220 is provided at the top of the first heat sink 300 and the support columns 170, the second electronic control board 220 is clamped between the first heat sink 300 and the support columns 170. When the support columns 170 are positioned, the side of the second control board 220 facing the support column 170 can form a good space. This space is formed by the height difference between the support column 170 and the cavity wall of the mounting cavity 130. This space facilitates heat dissipation from the second control board 220. Simultaneously, the housing 100 is provided with a first heat dissipation hole 140, located above the first heat sink 300. Heat in this space can be discharged to the outside of the housing 100 through the first heat dissipation hole 140, further improving the heat dissipation effect. Furthermore, the side of the second control board 220 facing the first heat sink 300 allows the heat generated on the second control board 220 to be absorbed by the first heat sink 300, further improving the heat dissipation effect of the second control board 220. At the same time, the first control board 210 is located at the bottom of the first heat sink 300. The heat generated by the first control board 210 during use can also be absorbed by the first heat sink 300, further improving the thermal conductivity of the first heat sink 300. It is understood that in this embodiment, the first control board 210 and the second control board 220 are stacked, which makes the structure of the control unit 200 more compact in the horizontal direction and also improves the heat dissipation effect of the control unit 200. Furthermore, the first heat sink 300 is fixed to the support column 170 by screws, wherein the screws pass through the second plate of the first heat sink 300 and the second control board 220, and then connect to the support column 170.
[0056] In one embodiment, reference Figure 6 , Figure 7 The first heat sink 300 has a first clearance space 320 at its bottom, which is used to avoid electrical components on the first electronic control board 210. The first heat sink 300 has a second clearance space 330 at its top, which is used to avoid electrical components on the second electronic control board 220. Furthermore, under the action of the first clearance space 320 and the second clearance space 330, the first plate and the second plate can fit better with the first heat sink 300. On the one hand, it is convenient to fix the first plate at the bottom of the first heat sink 300 and for the first heat sink 300 and the support column 170 to hold the second plate. On the other hand, it also allows the first heat sink 300 to fit better with the electrical components on the first plate and the second plate, and can better absorb the heat generated by the electrical components during operation.
[0057] In one embodiment, reference Figure 2 , Figure 4 , Figure 5 The camera device also includes a second heat sink 400, which is located above the first electronic control board 210 and fixed to the first heat sink 300. It can be understood that the first electronic control board 210 is located between the first heat sink 300 and the second heat sink 400. At this time, the heat generated by the first electronic control board 210 during operation can be absorbed by the first heat sink 300 and the second heat sink 400, improving the heat dissipation effect of the first electronic control board 210. At the same time, under the action of the second heat sink 400, the heat conduction of the first electronic control board 210 by the first heat sink 300 can be shared.
[0058] In one embodiment, reference Figure 9 The second heat sink 400 is provided with a third clearance space 410, which is used to avoid electrical components on the first electronic control board 210. Under the action of the third clearance space 410, the second heat sink 400 and the electrical components on the first electronic control board 210 can have a better fit, further improving the heat conduction effect of the second heat sink 400 on the first electronic control board 210.
[0059] In one embodiment, reference Figure 5 The second heat sink 400 is fixed to the first heat sink 300, enabling the second heat sink 400 and the third heat sink to clamp the first electronic control board 210. In some embodiments, the second heat sink 400 is fixed to the first heat sink 300 by screws, wherein the screws pass through the plates on the second heat sink 400 and the first electronic control board 210.
[0060] In one embodiment, reference Figure 5 , Figure 8 The second heat sink 400 has multiple first heat sinks 420 at the end opposite to the first control board 210. The housing 100 has multiple second heat dissipation holes 150, and the multiple first heat sinks 420 extend into part of the second heat dissipation holes 150. It can be understood that the number of second heat dissipation holes 150 is greater than the number of first heat sinks 420. At the same time, the first heat sinks 420 extending into the second heat dissipation holes 150 allows part of the structure of the second heat sink 400 to have better contact with the air outside the housing 100, further improving the heat dissipation effect. Meanwhile, for the other part of the second heat dissipation holes 150 that are not extended into by the first heat sinks 420, this part of the second heat dissipation holes 150 can play a role in heat dissipation for other spaces inside the mounting cavity 130.
[0061] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The housing 100 includes a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 are fixed together by a detachable structure. Furthermore, the first housing 110 and the second housing 120 can be fixed together by screws. The second heat dissipation hole 150 is opened in the first housing 110, and the first heat dissipation bracket 300 is fixed in the second housing 120. The first heat dissipation hole 140 is opened in the second housing 120. In this way, when external air circulates in the camera device, the air can enter from the top of the housing 100 and then flow out from the bottom, which facilitates the airflow inside the housing 100. The good airflow can easily carry away the heat inside the housing 100.
[0062] In one embodiment, reference Figure 2 , Figure 5The camera device also includes a first camera 500, which is electrically connected to the electronic control unit 200. The mounting cavity 130 allows the first housing 110 to protrude outward to form a protrusion 160. The first camera 500 is installed in the protrusion 160 and is located above the second heat sink 400. When the electronic control unit 200 includes a first electronic control board 210 and a second electronic control board 220, the video recorded by the first camera 500 can be stored by the first electronic control board 210, and the user can obtain the video stored in the first electronic control board 210 through the second electronic control board 220. It is understandable that since the protrusion 160 is formed in the first housing 110 and the first camera 500 is installed in the protrusion 160, that is, the first camera 500 is installed in the first housing 110, this arrangement can make the structure of the first housing 110 relatively compact. At the same time, in order to dissipate heat from the first camera 500, the second heat sink 400 is provided with a plurality of second heat sinks 430, and the plurality of second heat sinks 430 extend into the protrusion 160.
[0063] In one embodiment, reference Figure 2 , Figure 5 The camera device also includes a mounting bracket 800, which is fixedly disposed within the protrusion 160. The first camera 500 is mounted on the mounting bracket 800. Furthermore, the mounting bracket 800 is fixedly disposed within the protrusion 160 by means of screws, which can also be understood as the mounting bracket 800 being connected to the first housing 110 by means of screws. Furthermore, the mounting bracket is also provided with a third heat dissipation bracket 700, which is used to further dissipate heat from the first camera 500.
[0064] In one embodiment, reference Figure 2 , Figure 5 , Figure 6The camera device further includes a second camera 600, which is electrically connected to the electronic control unit 200. The second camera 600 is disposed in the mounting cavity 130. A mounting position 310 extends outward from the periphery of the first heat sink 300, and the second camera 600 is mounted in the mounting position 310. It can be understood that the first heat sink 300 can also serve as a mounting bracket for the second camera 600 and provide heat dissipation for the second camera 600. Furthermore, the first camera 500 is used to acquire image information from the front of the housing 100, and the second camera 600 is used to acquire image information from the rear of the housing 100. That is, the camera device in this embodiment can acquire image information from two different directions during use: one direction is the image information from the front of the housing 100, and the other direction is the image information from the rear of the housing 100. It should be noted that during use, the first camera 500 is located below the second camera 600.
[0065] Furthermore, in some embodiments, reference is made to... Figure 1 The camera device also includes a mounting base 900 and a positioning component 10. The mounting base 900 is hinged to the housing 100, and the positioning component 10 is used to position the housing 100 in a preset position. Furthermore, the mounting base 900 can be connected to the vehicle body. The mounting base 900 and the housing 100 can be connected by a universal joint, which includes a ball joint, a ball joint seat, and two connecting rods. One connecting rod connects the ball joint and the mounting base 900, and the other connecting rod connects the ball joint seat and the housing 100. The ball joint seat can contract and expand. An adjusting nut is provided on the ball joint seat. By rotating the adjusting nut, the friction between the ball joint seat and the ball joint can be increased, thereby fixing the ball joint in a preset position, and thus enabling the positioning component 10 to position the housing 100 in a preset position. In some embodiments, the positioning component 10 includes a first connecting portion 11 and a second connecting portion 12, wherein the first connecting portion 11 protrudes from the fixing base 900, and the second connecting portion 12 protrudes from the housing 100. Specifically, the second connecting portion 12 protrudes from the second housing 120, and two second connecting portions 12 are configured. The first connecting portion 11 is disposed between the two second connecting portions 12, and the first connecting portion 11 and the second connecting portion 12 are connected by a bolt and nut. In some embodiments, the second connecting portion 12 has a certain elasticity. The bolt passes through the first connecting portion 11 and the second connecting portion 12, and then connects with the nut. By tightening the nut, the two second connecting portions 12 can clamp the first connecting portion 11. By increasing the friction between the second connecting portion 12 and the first connecting portion 11, the second connecting portion 12 and the first connecting portion 11 are fixed, thereby enabling the positioning component 10 to position the housing 100 at a preset position.
