Description

Technical Field

[0001] The utility model relates to the technical field of photographic accessories, in particular to a base type camera heat dissipation mechanism. Background Art

[0002] A camera is an optical instrument used to capture and store images or videos. It uses the principle of optical imaging to focus the light reflected by the scene being photographed through the lens and form an image on a photosensitive material or electronic image sensor. The development of cameras has a long history. From the initial film cameras to modern digital cameras, to the built-in camera functions of smartphones, the continuous advancement of technology has made photography more convenient and popular.

[0003] When the camera is working continuously for a long time or under high-intensity shooting conditions, it will generate a lot of heat. In order to ensure the stable operation of the camera and extend its service life, these cameras usually have heat dissipation channels to effectively dissipate heat. Figure 1 As shown, in the prior art, heat dissipation ports are usually opened at the bottom and sides of the camera housing, and each heat dissipation port cooperates with the interior of the camera to form a heat dissipation channel, which dissipates the heat inside the camera to the external environment by natural convection.

[0004] During use, it was found that although the heat dissipation channel can guide the heat from the inside of the camera to the external environment, it cannot quickly discharge the heat inside the camera. During long-term continuous work, when the heat inside the camera cannot be quickly discharged, overheating and freezing may easily occur. For this reason, we proposed a base-type camera heat dissipation mechanism to effectively solve the above-mentioned drawbacks. Utility Model Content

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 2 to 6 , a base-type camera heat dissipation mechanism, including a connection seat 1, a threaded connection assembly 2, a heat dissipation fan 3 and an air guide channel 4. Each component cooperates with each other to form a base-type heat dissipation mechanism installed at the bottom of the camera, actively dissipating heat inside the camera to ensure the heat dissipation effect.

[0029] Among them, the connection seat 1 is located at the bottom of the camera. Specifically, as Figure 3 and Figure 6As shown, the connection seat 1 includes a bottom plate 101 and a side plate 102 fixed on the bottom plate 101. In this embodiment, the side plate 102 can be integrally formed with the bottom plate 101, or can be fixedly connected to the bottom plate 101 in a detachable connection manner. The bottom plate 101 and the side plate 102 cooperate to form a horizontal L-shaped structure. The design of the horizontal L-shaped structure can enable other components to be compactly installed on the horizontal L-shaped structure without being too abrupt, thereby improving the aesthetics. The threaded connection assembly 2 is arranged on the top of the bottom plate 101, and the heat dissipation fan 3 is detachably arranged at the bottom of the bottom plate 101, and the heat dissipation fan 3 adopts a centrifugal fan, and the air guide channel 4 is opened in the side plate 102. Specifically in this embodiment, the outer contour of the centrifugal fan coincides with the outer contour of the bottom plate 101, and the bottom surface of the centrifugal fan is flush with the bottom surface of the side plate 102. The overall structure is relatively compact and flat, which is conducive to improving the comfort during use.

[0030] In another embodiment of the present application, the cooling fan 3 can be replaced with an axial flow fan, and the thickness of the bottom plate 101 needs to be appropriately increased. In this case, the bottom plate 101 and the side plate 102 no longer form a horizontal L-shaped structure, and the axial flow fan may not coincide with the outer contour of the bottom plate 101. When an axial flow fan is used, the air outlet of the axial flow fan faces the bottom plate 101, and a wind guiding or wind gathering curved surface is designed on the bottom plate 101 and the side plate 102 to introduce the airflow generated by the axial flow fan into the wind guiding channel 4, thereby dissipating heat for the camera.

[0031] In another embodiment of the present application, the cooling fan 3 can also be an exhaust fan. Compared with the cooling method of centrifugal fans and axial flow fans blowing air into the cooling channel, the exhaust fan is used to generate negative pressure in the cooling channel, thereby drawing the air in the camera cooling channel outward, which can also increase the air convection speed inside the cooling channel to improve the camera cooling efficiency.

[0032] Secondly, the threaded connection assembly 2 is arranged on the top of the connection base 1 and is screwed with the 1 / 4 threaded hole at the bottom of the camera to fasten the connection base 1 and the camera. Figure 1 As shown, in the prior art, the bottom of the camera usually has a 1 / 4 threaded hole, which is a standard configuration in camera design. The diameter of this threaded hole is 1 / 4 inch (about 6.35 mm), which is one of the interfaces equipped with internationally common professional cameras. It is mainly used to install accessories such as tripods, bases, quick release plates, etc. to ensure the stability and safety of the camera during shooting. Therefore, the present application specially designs a threaded connection component 2 that can cooperate with the 1 / 4 threaded hole at the bottom of the camera, so that the connecting seat 1 can be installed and fixed on the bottom of the camera.

[0033] Specifically, if Figure 3 and Figure 5As shown, the threaded connection assembly 2 includes a mounting groove 201 provided at the bottom of the base plate 101, and a turntable 202 partially extending out of the mounting groove 201 is movably provided in the mounting groove 201, and the user can manually rotate the turntable 202. The top surface of the turntable 202 is in contact with the base plate 101, and the bottom surface of the turntable 202 is in contact with the cooling fan 3, so that the turntable 202 is not easy to move axially, thereby improving the stability of the connection between the connection seat 1 and the camera. A coaxially arranged screw male head 203 is fixedly connected to the top of the turntable 202, and when the turntable 202 is rotated, the screw male head 203 can be driven to rotate. A through hole 204 is penetrated on the base plate 101, and the screw male head 203 is movably passed through the through hole 204 in the vertical direction and is spirally matched with the 1 / 4 threaded hole provided at the bottom of the camera. The screw male head 203 can be tightened or loosened by rotating the turntable 202, so that the connection seat 1 can be installed to the bottom of the camera or removed from the bottom of the camera.

[0034] Preferably, a plurality of anti-skid protrusions 205 are provided at intervals along the circumferential direction on the side surface of the turntable 202 . Each anti-skid protrusion 205 is integrally formed with the turntable 202 , which can increase the friction force, thereby facilitating the user to turn the turntable 202 by hand.

[0035] In addition, the cooling fan 3 is detachably arranged at the bottom of the connecting base 1. Figure 5 As shown, fixing holes 5 are provided at the four corners of the heat dissipation fan 3, and connecting screws 6 are movably inserted in each fixing hole 5, and connecting screw holes 7 that are screwed together with each connecting screw 6 are provided on the bottom plate 101; the heat dissipation fan 3 is detachably connected to the bottom plate 101 through the cooperation of the connecting screws 6 and the connecting screw holes 7. After loosening the connecting screws 6, the heat dissipation fan 3 can be separated from the connecting seat 1, so that the heat dissipation fan 3 can be inspected or replaced; at the same time, the turntable 202 and the screw male head 203 in the mounting groove 201 can be conveniently replaced.

[0036] In this embodiment, if Figure 4 and Figure 6 As shown, the air guide channel 4 is arranged in the connection seat 1, one of the ports of the air guide channel 4 is connected to the air outlet of the cooling fan 3, and the other port of the air guide channel 4 is connected to the cooling channel provided at the bottom of the camera. When the cooling fan 3 is working, the high-speed airflow generated can enter the camera through the air guide channel 4 and the cooling port at the bottom of the camera, and then be discharged through the cooling port on the side of the camera, thereby cooling the camera. It should be noted that the cooling fan 3 used in this application is a prior art, and the connections between the various components are also prior art, so the connection relationship and principle thereof will not be described in detail here.

[0037] When in use, the connection base 1 is placed at the bottom of the camera, and then the turntable 202 is turned by hand to drive the male screw 203 to be screwed into the 1 / 4 threaded hole at the bottom of the camera, so that the connection base 1 can be installed and fixed at the bottom of the camera. When the cooling fan 3 is working, the high-speed airflow it generates enters the camera through the air guide channel 4 and the heat dissipation port at the bottom of the camera, and then is discharged through the heat dissipation port on the side of the camera, so that the heat inside the camera can be quickly discharged.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
