Description

Technical Field

[0001] The utility model relates to the technical field of photographic accessories, and particularly relates to an active camera heat dissipation mechanism. Background Art

[0002] When a camera is used for high-intensity shooting or continuous use for a long time, its internal temperature will rise rapidly. Without effective heat dissipation measures, the performance of the camera may decline, such as the shutter speed becoming slower, the focusing accuracy decreasing, and the image noise increasing. Therefore, heat dissipation is crucial for maintaining the shooting performance of the camera.

[0003] As Figure 1 shown, in the prior art, heat dissipation channels are usually arranged inside the camera, and the two ports of the heat dissipation channels are respectively located at the bottom and side of the camera, and the heat inside the camera is dissipated to the external environment through natural convection, which is simple and effective.

[0004] However, the above method can only passively dissipate heat from the camera, and the heat dissipation effect is relatively slow. When the camera is used for a long time, it is easy to overheat and freeze. Therefore, we propose an active camera heat dissipation mechanism to solve the above disadvantages well. Content of the Utility Model

[0008] An installation cavity arranged inside the connecting frame and communicating with one end port of the camera heat dissipation channel;

[0009] An active ventilation component arranged inside the installation cavity and communicating with the external environment.

[0010] Optionally, the installation cavity is opened on the side of the connecting frame close to the camera, and a cover plate adapted to the installation cavity is covered on the connecting frame, and the cover plate and the installation cavity cooperate with each other to form a ventilation groove communicating with the port of the camera heat dissipation channel.

[0011] Optionally, a plurality of flow guiding blocks are arranged inside the installation cavity between the active ventilation component and the ventilation groove, and the gaps between the flow guiding blocks form a flow guiding channel between the active ventilation component and the ventilation groove.

[0012] Optionally, the active ventilation component includes a ventilation fan disposed in the installation cavity, and a ventilation opening connected to the ventilation fan is opened on the outside of the connecting frame.

[0013] Optionally, the ventilation fan is a centrifugal fan, and the air inlet end of the centrifugal fan is connected to the ventilation port.

[0014] Optionally, the ventilation fan is an exhaust fan, and an air outlet of the exhaust fan is connected to the air vent.

[0015] Compared with the prior art, the present invention provides an active camera heat dissipation mechanism, which has the following beneficial effects:

[0016] 1. The utility model can cooperate with the heat dissipation channel of the camera itself through the mutual cooperation between the connecting frame, the installation cavity and the active ventilation component, actively allowing air to quickly flow through the heat dissipation channel of the camera itself, thereby quickly dissipating the heat inside the camera to the external environment.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0025] Example: See Figures 2 to 6 An active camera heat dissipation mechanism includes a connecting frame 1, a mounting cavity 2 and an active ventilation component 3. Through the mutual cooperation between the connecting frame 1, the mounting cavity 2 and the active ventilation component 3, the heat inside the camera can be quickly dissipated to the external environment. The structure is simple and compact, and the heat dissipation effect is good.

[0026] The connecting frame 1 is used to be fixedly connected to the camera. The connecting frame 1 can be a camera cage or a camera L plate purchased on the market. The camera cage or the camera L plate can be fixed on the camera by screwing with a 1 / 4 screw and a 1 / 4 threaded hole on the bottom of the camera. This is a prior art and will not be described in detail here. Figure 2 and Figure 3 As shown, an Arca quick-release plate is fixedly connected to the outer side of the connecting frame 1, which can quickly connect the camera to a tripod, a gimbal, or other photographic support equipment.

[0027] Secondly, the installation cavity 2 is arranged in the connection frame 1 and is connected to one of the ports of the camera heat dissipation channel. Figures 4 to 6 As shown, the installation cavity 2 is opened on the side of the connecting frame 1 close to the camera, and a cover plate 4 adapted to the installation cavity 2 is provided on the connecting frame 1. The cover plate 4 can prevent the airflow from being discharged through other places as much as possible, so that the airflow is not easy to be turbulent inside the installation cavity 2. The cover plate 4 cooperates with the installation cavity 2 to form a ventilation slot 5 connected to the port of the camera heat dissipation channel. When the active ventilation component 3 is working, the airflow can smoothly flow through the installation cavity 2, the ventilation slot 5 and the port of the camera heat dissipation channel.

[0028] Preferably, a plurality of guide blocks 6 located between the active ventilation component 3 and the ventilation slot 5 are provided in the installation cavity 2, and the gaps between the guide blocks 6 constitute guide channels located between the active ventilation component 3 and the ventilation slot 5, so that high-speed airflow can flow smoothly between the active ventilation component 3 and the ventilation slot 5.

[0029] Finally, the active ventilation component 3 is disposed in the installation cavity 2 and is in communication with the external environment. Figure 5 As shown, the active ventilation component 3 includes a ventilation fan 301 disposed in the installation cavity 2, and a vent 302 is provided on the outside of the connecting frame 1 to communicate with the ventilation fan 301, so that the ventilation fan 301 can communicate with the external environment. When the ventilation fan 301 is working, it can actively make the air flow quickly pass through the camera heat dissipation channel, thereby improving the heat dissipation effect of the camera.

[0030] In this embodiment, the ventilation fan 301 can be a centrifugal fan. The air inlet end of the centrifugal fan is in communication with the ventilation port 302, and it can blow high-speed air into the camera heat dissipation channel, thereby dissipating heat from the camera. The ventilation fan 301 can also be an exhaust fan. The air outlet end of the exhaust fan is in communication with the ventilation port 302, and it can extract the high-temperature gas in the camera heat dissipation channel, thereby dissipating heat from the camera.

[0031] During use, the connecting frame 1 is installed and fixed on the camera. When heat dissipation of the camera is required, the active ventilation component 3 operates to blow air into or extract air from the camera interior, thereby achieving the effect of rapid heat dissipation and preventing the camera from overheating and crashing.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.
