Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) gimbal camera technology, specifically to a heat dissipation structure for a gimbal camera and a gimbal camera. Background Technology

[0002] With the continuous development of drone gimbal cameras, these cameras typically incorporate high-heat-generating components such as thermal imaging lens modules. Existing gimbal cameras, for example, usually house thermal imaging lens modules within the front housing. As a high-heat-generating image module, the thermal imaging lens module's own heat can only be transferred to the surrounding space within the housing through natural heat conduction. Because convection between the internal and external air is difficult, the heat conduction efficiency is low, thus affecting the temperature measurement accuracy of the thermal imaging lens module.

[0003] Therefore, it is particularly important to provide a heat dissipation structure for a gimbal camera and a gimbal camera in general. Utility Model Content

In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0021] According to a first aspect of this application, a heat dissipation structure for a gimbal camera is proposed. The heat dissipation structure of the gimbal camera according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0022] Please see Figure 1 and Figure 2 The heat dissipation structure of the gimbal camera includes a housing 1 with an accommodating space, and a heat-conducting bracket 3 and an active heat dissipation assembly 4 disposed within the accommodating space for dissipating heat from the heat-generating component 2. The heat-generating component 2 and the active heat dissipation assembly 4 are positioned opposite each other at opposite ends of the accommodating space. The two ends of the heat-conducting bracket 3 are respectively used to connect the heat-generating component 2 and the active heat dissipation assembly 4, thereby transferring the heat from the heat-generating component 2 to the active heat dissipation assembly 4 for heat dissipation.

[0023] In one optional embodiment, the heat-generating component 2 can be at least any one of the following: a thermal imaging lens module, a laser rangefinder lens module, a zoom lens module, a fixed-focus lens module, a photosensitive device, a battery, and a processor mounted on the gimbal camera.

[0024] In this embodiment, the heating element 2 is specifically a thermal imaging lens module, and the heat-conducting bracket 3 is a metal bracket.

[0025] In one specific embodiment, the housing 1 includes a front housing 11 and a rear housing 12 that are interlocked with each other, and the active heat dissipation assembly 4 includes heat dissipation fins 41 and a cooling fan 42. The inner wall of the front housing 11 is fixed with a mounting bracket 5 by screws, and the heat-generating component 2 is installed inside the mounting bracket 5 by screws. The top of the rear housing 12 has an air outlet 121, and the outer periphery of the heat dissipation fins 41 is abutted against the inner wall of the rear housing 12 near the air outlet 121. The cooling fan 42 is mounted on the heat dissipation fins 41.

[0026] In one specific embodiment, the two ends of the heat-conducting bracket 3 are used to connect the mounting bracket 5 and the heat dissipation fins 41, respectively. The heat emitted by the heat-generating component 2 is conducted to the heat-conducting bracket 3 via the mounting bracket 5, and then conducted to the heat dissipation fins 41 via the heat-conducting bracket 3. Finally, the heat is actively dissipated by the cooling fan 42 and discharged from the air outlet 121, thereby greatly improving the heat conduction efficiency of the heat-generating component 2 and ensuring the stability of the function of the heat-generating component 2.

[0027] In one specific embodiment, the heat-conducting bracket 3 has an "L" shaped structure. One end of the heat-conducting bracket 3 is used to connect to the mounting bracket 5, and the other end of the heat-conducting bracket 3 is bent into a connecting part 31. The heat dissipation fin 41 has a contact surface 411 on the side close to the heat-conducting bracket 3, and the connecting part 31 is connected to the contact surface 411.

[0028] By setting the fixed end of the heat conduction bracket 3 to connect to one end of the heat dissipation fin 41, the heat conduction bracket 3 can be fastened to the front shell 11 together with the rear shell 12 when installing the shell 1, making the installation of the shell 1 more convenient.

[0029] In one specific embodiment, a heat-conducting layer 6 is provided between one end of the heat-conducting bracket 3 and the mounting bracket 5. By providing the heat-conducting layer 6, the heat on the mounting bracket 5 can be better conducted to the heat-conducting bracket 3, thereby further improving the heat conduction efficiency.

[0030] In this embodiment, since the heat-conducting bracket 3 only abuts against the mounting bracket 5 and there is no rigid connection, the heat-conducting layer 6 set in the middle is a heat-conducting silicone grease sheet.

[0031] In one specific embodiment, a thermally conductive filler (not shown in the figure) is provided between the connecting part 31 and the mating surface 411. By providing the thermally conductive filler, the heat on the thermally conductive bracket 3 can be better conducted to the heat dissipation fins 41, thereby further improving the thermal conductivity.

[0032] In this embodiment, since the heat-conducting bracket 3 and the heat dissipation fin 41 are rigidly connected through the connecting part 31 and the mating surface 411, in order to avoid the gap between the two from allowing air to enter and affecting the heat conduction effect, the heat-conducting filler in the middle is heat-conducting grease. As a liquid substance, heat-conducting grease can fill the gap between the connecting part 31 and the mating surface 411 very well.

[0033] In summary, the heat dissipation structure for a gimbal camera proposed in this application has the following beneficial effects: By setting up the heat-conducting bracket 3 and the active heat dissipation component 4, the heat of the heat-generating component 2 is conducted from the heat-generating component 2 body through the mounting bracket 5 and the heat-conducting layer 6 to the heat-conducting bracket 3. The heat-conducting bracket 3 then conducts the heat to the heat-dissipating fins 41 through the heat-conducting filler. Finally, the heat is actively dissipated by the cooling fan 42 and discharged from the air outlet 121, thereby greatly improving the heat conduction efficiency of the heat-generating component 2 and ensuring the stability of the function of the heat-generating component 2.

[0034] According to a second aspect of this application, a gimbal camera is also proposed. See [link to relevant documentation]. Figure 1 The gimbal camera includes the gimbal camera body and the heat dissipation structure of the gimbal camera mentioned in the first aspect above.

[0035] In one specific embodiment, the heat-generating component 2 can be at least any one of the following: a thermal imaging lens module, a laser rangefinder lens module, a zoom lens module, a fixed-focus lens module, a photosensitive device, a battery, and a processor mounted on the gimbal camera.

[0036] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
