DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 2 to 5 As shown, an embodiment of the utility model provides a camera radiator for a camera 10 provided with a screen groove (not shown in the figure), which includes a shell 20, a cooling fan 30 and a fixing assembly 40; a first cooling channel 210 is penetrated by the shell, and a side of the shell facing the camera 10 is enclosed with the camera 10 to form a second cooling channel 220, and the first cooling channel 210 is connected to the second cooling channel 220; it is arranged in the first cooling channel 210 and is used to guide air from the first cooling channel 210 to the second cooling channel 220; the fixing assembly 40 is used to fix the camera radiator to the screen groove.

[0034] When the camera radiator of this embodiment is used, the fixing component 40 fixes the camera radiator to the screen groove on the camera 10, so that the camera radiator is fixed on the camera 10. Under the action of the cooling fan 30, the side of the shell 20 facing away from the camera 10 draws air into the first cooling channel 210. Then, it enters the second cooling channel 220 from the first cooling channel 210. The second cooling channel 220 is formed by the camera 10 and the shell 20, so the contact time and contact area of ​​the flowing air with the camera 10 are larger, thereby achieving a better cooling effect. The implementation of the camera radiator in the utility model can solve the problem of low heat dissipation efficiency and instability of the external camera radiator in the prior art.

[0035] Air duct design is crucial to the heat dissipation effect of electronic products. Reasonable air ducts can effectively improve heat dissipation efficiency and reduce hardware temperature, thereby ensuring the stable operation of electronic products.

[0036] In this embodiment, compared with the existing camera heat sink, the blowing direction of the heat dissipation fan 30 is exactly opposite. In addition, a part of the inner wall of the second air duct is formed by the camera 10 to achieve a better heat dissipation effect.

[0037] This is mainly because the camera 10 is usually placed where the screen is placed, and a screen groove is exposed after the screen is flipped. Therefore, the air inlet of the camera radiator in the prior art is generally arranged around the side of the radiator and is relatively scattered. In other words, the air duct in the prior art is basically inside the camera radiator, and the contact area between the air and the camera 10 is basically only equal to the size of the cooling fan 30.

[0038] In one embodiment, the fixing assembly 40 includes an abutment member 410 and a driving member 420, the abutment member 410 is movably connected to the shell 20, and the driving member 420 is respectively connected to the abutment member 410 and the shell 20, and the driving member 420 is used to drive the abutment member 410 and the shell 20 to abut against opposite sides of the screen groove respectively.

[0039] The driving member 420 drives the abutting member 410 to move, so that the abutting member 410 and the housing 20 are respectively connected to the opposite sides of the screen groove, thereby achieving the purpose of fixing the camera radiator.

[0040] In some cases, the fixing component may also be a suction cup or a magnetic method to fix the camera heat dissipation component to the camera.

[0041] In one embodiment, a ring flange 110 is disposed on a side of the housing facing the camera 10 . The ring flange 110 has a notch 231 . The notch 231 constitutes an outlet of the second heat dissipation channel 220 .

[0042] In this embodiment, a ring flange 110 is provided on the housing 10, and a notch 231 is provided, so that all the air can be discharged from the notch 231. The purpose of doing so is to increase the flow rate of the air in the second heat dissipation duct 220 to a certain extent and form a stable convection channel, thereby achieving a better heat dissipation effect.

[0043] The notch 231 is generally located on the side close to the screen of the camera 10, mainly because the screen groove itself has a notch when it is folded toward the screen. This arrangement can ensure smooth air outlet of the second heat dissipation duct 220, and there is no need to set the height of the annular flange 110 to be higher than the height of the screen groove.

[0044] In one embodiment, the annular flange 110 is made of a flexible material so that the annular flange 110 can fit the camera 10 .

[0045] The purpose of the flexible material is to prevent the camera radiator from bumping against the camera 10. The flexible material can be selected from rubber, silicone or high-density sponge material and the like.

[0046] In one embodiment, a positioning flange 240 is provided on the side of the shell 20 away from the abutment 410, and a clamping portion 4110 is provided on the side of the abutment 410 away from the positioning flange 240. The positioning flange 240 and the clamping portion 4110 are used to abut and cooperate with the opposite sides of the screen groove respectively.

[0047] In some embodiments, when there is a gap between the display screen and the body, the positioning flange 240 and / or the snap-on portion 41103 may also be inserted into the gap to position the installation of the camera radiator; of course, in order to improve the connection firmness between the camera radiator and the camera 10, an anti-slip layer, anti-slip sticker or other anti-slip structure may also be provided at the contact portion between the positioning flange 240 and the snap-on portion 4110 and the screen groove 2011 to increase friction.

[0048] In the camera radiator of the present embodiment, by setting a driving member 420 to cooperate with the abutment member 410, the abutment member 410 and the housing 20 can be driven to cooperate to fix the camera radiator to the screen groove, thereby enabling the camera radiator to be applied to cameras 10 of different models, with a simple structure and convenient use.

[0049] It should be noted that, in one of the cameras 10 to which the camera radiator in this embodiment can be applied, the camera 10 includes a body and a display screen, a screen groove is provided on the body, and the display screen is movably connected to the body; when in a folded state, the display screen is accommodated in the screen groove, and when in an unfolded state, the display screen is located outside the screen groove, so that the camera radiator can be installed in the screen groove, and a plug-in groove is formed between the rotating shaft and the body, and the clamping portion 4110 is clamped in cooperation with the plug-in groove.

[0050] When installing the camera radiator of this embodiment, first move the clamping portion 4110 toward the camera 10 and insert the clamping portion 4110 into the insertion slot to position the camera radiator and the camera 10. Then, flip the positioning flange 240 of the shell 20 toward the screen groove, and abut the inner wall of the screen groove through the positioning flange 240. By setting the fixing component 40, the camera radiator can be driven to be fixedly connected to the screen groove.

[0051] In one embodiment, the shell 20 is provided with an active cavity 250, the abutment member 410 is slidably matched with the active cavity 250, and the driving member 420 is accommodated in the active cavity 250. The driving member 420 is used to drive the abutment member 410 to move along the length direction of the active cavity 250 so that the abutment member 410 and the shell 20 are respectively pressed against the opposite sides of the screen groove.

[0052] In this embodiment, the abutment member 410 has the power to move relative to the housing 20 under the driving action of the driving member 420, and can abut against the opposite sides of the screen groove in the straight direction of the camera radiator. By arranging the driving member 420 to cooperate with the abutment member 410, the total length of the camera radiator can be adjusted so that the camera radiator is fixedly connected to the screen groove; when the camera radiator needs to be removed, the abutment member 410 only needs to be moved in the opposite direction to release the camera radiator, thereby enabling the camera radiator to be applied to cameras 10 of different models (specifically, in screen grooves of different sizes).

[0053] In other embodiments, the abutment 410 may also be rotatably connected to the shell 20. For example, the end of the abutment 410 is rotatably connected to the shell 20 and can swing relative to the shell 20 within a fan-shaped range. At this time, the abutment 410 can be driven by the driving member 420 so that the abutment 410 can also be pressed against the inner wall of the screen groove to achieve the positioning function.

[0054] Of course, in some embodiments, the abutment 410 may also abut against the adjacent two side walls of the screen groove together with the shell 20 , which is specifically determined according to the model of the camera 10 and the design requirements of the camera radiator, and is not limited here.

[0055] In one embodiment, a guide groove 2510 connected to the active cavity 250 is formed on the side wall of the active cavity 250, and a guide portion 4120 is protruded from one side of the abutment member 410. The guide portion 4120 is slidably matched with the guide groove 2510, and the extension direction of the guide groove 2510 is parallel to the length direction of the active cavity 250.

[0056] In this embodiment, the guide groove 2510 is concavely arranged on the inner wall of the active cavity 250, and the guide portion 4120 is convexly arranged on the side wall of the abutment 410. When the abutment 410 is assembled in the active cavity 250, the movement of the abutment 410 can be guided by the sliding cooperation between the guide portion 4120 and the guide groove 2510. At the same time, the movement of the abutment 410 in a direction perpendicular to the guide portion 4120 can be limited to improve the smoothness and accuracy of the movement of the abutment 410.

[0057] In a preferred embodiment, the number of guide portions 4120 and guide grooves 2510 is at least two groups, and the two groups of guide grooves 2510 and guide portions 4120 are symmetrically arranged on opposite sides of the abutment 410, thereby further improving the movement smoothness and movement accuracy of the abutment 410.

[0058] In one embodiment, a limiting portion 4130 is protruded from one side of the abutment 410, and the limiting portion 4130 is located in the active cavity 250. The abutment 410 extends from the opening of the active cavity 250, and the orthographic projection of the limiting portion 4130 on the plane where the opening is located is at least partially located outside the opening.

[0059] In this embodiment, the abutment 410 can extend from the opening of the active cavity 250 to realize the adjustment function of the abutment 410. At this time, the thickness dimension of the abutment 410 is not greater than the opening width dimension of the active cavity 250 (the dimension in the same direction can also be considered as the length dimension, etc., which is only for the convenience of description and is not the only limitation here). By providing a limiting portion 4130 on the outer wall of the abutment 410, and at the same time, the limiting portion 4130 is at least partially located outside the opening projection of the active cavity 250, the thickness of the abutment 410 at the limiting portion 4130 can be made greater than the opening width of the active cavity 250. When the abutment 410 moves to the end of the path in the active cavity 250, the limiting portion 4130 can abut against the inner wall of the active cavity 250 to limit the movement of the abutment 410 and prevent the abutment 410 from falling out of the active cavity 250.

[0060] In one embodiment, the abutting member 410 is provided with a fixing column 4140 , and the driving member 420 is a spring, and one end of the driving member 420 is engaged with the fixing column 4140 .

[0061] With this arrangement, when assembling the fixing component 40, the driving member 420 can be fixed on the fixing column 4140 so that the driving member 420 is connected to the abutment member 410. After the fixing component 40 is installed in the active cavity 250, the end of the driving member 420 away from the fixing column 4140 can abut against the inner wall of the active cavity 250 to realize the driving function of the driving member 420.

[0062] In one embodiment, the camera radiator includes a battery 50 and a control assembly 60 . The battery 50 and the control assembly 60 are both disposed in the housing 20 , and the control assembly 60 is electrically connected to the battery 50 and the cooling fan 30 , respectively.

[0064] In one embodiment, the control assembly 60 includes a circuit board 610 , which is disposed in the housing 20 and electrically connected to the battery 50 and the cooling fan 30 ;

[0065] The control assembly 60 further includes a switch 620, which is electrically connected to the circuit board 610. The housing is provided with a key hole (not shown), and the switch 620 can be movably accommodated in the key hole.
