Description

Technical Field

[0001] The utility model relates to the technical field of camera of unmanned aerial vehicle, in particular to a heat dissipation structure for a camera used in an unmanned aerial vehicle. Background Art

[0002] At present, the low-altitude economy is gradually emerging in China, such as logistics distribution, manned flight, tourism consumption, emergency rescue, etc.

[0003] In the scenario of emergency rescue, unmanned aerial vehicles are more widely used. For example, when natural disasters such as earthquakes, floods, and mudslides occur in a certain place and cause communication interruption, the unmanned aerial vehicle can quickly rise to 100 meters within 5 minutes, continuously provide communication guarantees such as calls and Internet access for the disaster area, with a coverage area of up to 50 square kilometers, and can serve more than 5,000 mobile phone users at the same time; in addition, the unmanned aerial vehicle can be equipped with a camera to observe the disaster situation.

[0004] When the existing unmanned aerial vehicles generally equipped with cameras are working, there are generally such defects: the power of the unmanned aerial vehicle is insufficient, the heat dissipation of the unmanned aerial vehicle is insufficient, and the heat dissipation of the camera is insufficient. Since there are currently some fire-fighting unmanned aerial vehicles that can drag water hoses to a height of 100 meters, it is possible to consider setting up cables and engines, placing the engine on the ground, and the engine provides power to the unmanned aerial vehicle 100 meters high through the cable. Since it is a rescue unmanned aerial vehicle, its size does not need to pursue miniaturization too much, so some heat dissipation structures can be set inside the unmanned aerial vehicle to achieve this. However, the heat dissipation effect of the existing heat dissipation cameras on the market is not particularly ideal and has not been well solved.

[0005] Inside a camera, there are usually multiple functional circuit boards; during installation, multiple functional circuit boards are usually centrally installed on the bottom plate. When the functional circuit boards generate heat, the heat is extremely easy to concentrate at the bottom plate, which is not conducive to the dissipation of heat; in addition, there are individual functional circuit boards that generate heat extremely seriously and the heat dissipation effect is also not good.

[0006] Therefore, for the structure of the camera, the company disperses each functional circuit board to avoid concentration of heat, and in addition, replaces the individual ones with extremely serious heat generation with multiple small boards and performs additional cooling on the small boards. Summary of the Utility Model

[0007] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a heat dissipation structure for a camera used in an unmanned aerial vehicle. By dispersing each functional circuit board to avoid concentration of heat, replacing the individual ones with extremely serious heat generation with multiple small boards, and performing additional cooling on the small boards, good cooling inside the camera is achieved, and thus the camera can work for a long time.

[0008] It should be noted that currently, there are situations where there is a single functional circuit board, two functional circuit boards, or multiple functional circuit boards inside a camera on the market. Regarding the quantity and size of the circuit boards, it is necessary to fully consider interference and heat generation, which is difficult for general enterprises to achieve. For the camera carried by a drone during emergency rescue, this type of camera needs to implement more functions, so there are more internal functional modules. If the general internal layout of a camera is adopted, it will be difficult for the heat generated inside the camera to dissipate after working for a long time during emergency rescue. This solution addresses the above problems by improving the layout of the circuit boards inside the camera and designing a corresponding cooling mechanism.

[0009] The purpose of the present utility model is achieved through the following technical solutions: A heat dissipation structure for a camera used in a drone, including a camera housing and multiple functional circuit boards disposed inside it, with heat dissipation holes opened on the camera housing;

[0010] The multiple functional circuit boards are respectively disposed at the inner walls of the camera housing through support members, so that the multiple functional circuit boards are dispersed;

[0011] A spacing is formed between the functional circuit board and the inner wall of the camera housing;

[0012] When each functional circuit board generates heat, the heat is dispersed throughout the camera housing, and the heat dissipation route is: the spacing between the functional circuit board and the camera housing, or the space between the functional circuit boards - the heat dissipation holes - the outside.

[0013] As a preferred technical solution of the present application, the functional circuit board is composed of multiple small boards connected by cables; multiple small boards in one functional circuit board are disposed in different equidistant planes parallel to the inner wall of the camera housing, and a heat dissipation space is formed between the small boards in adjacent equidistant planes, forming a structure to avoid heat concentration on one board.

[0014] As a preferred technical solution of the present application, multiple cooling copper bars are fixed on the inner wall of the camera housing, and the cooling copper bars have cooling channels inside, and the cooling channels are communicated with an external water-cooled radiator through pipes;

[0015] That multiple small boards in one functional circuit board are disposed in different equidistant planes parallel to the corresponding inner wall of the camera housing means that: in the direction from close to the inner wall to far from the inner wall, the small boards in the first layer are supported on the cooling copper bars through short copper pipes and locked and fixed by single-headed hexagonal copper studs, and the small boards in the second layer are placed on the single-headed hexagonal copper studs in the lower layer and locked and fixed by other single-headed hexagonal copper studs; multiple small boards are placed and fixed in this way, and the small board farthest from the inner wall of the camera housing is locked and fixed by flat head screws;

[0016] The single-headed hexagonal copper stud is a hollow stud;

[0017] From the direction close to the inner wall to the direction away from the inner wall: A short copper tube is screwed onto the cooling copper bar -- multiple single-headed hexagonal copper studs are connected in series on the short copper tube by threads -- a flat-head screw is screwed on.

[0018] When water circulates along the cooling channel of the cooling copper bar, the cooling copper bar cools the area between the corresponding small board and the inner wall of the camera housing; when water circulates along the cooling channel of the cooling copper bar, part of the water enters the short copper tube and the hollow single-headed hexagonal copper stud, cooling the heat dissipation space between adjacent small boards. Since the small board is in direct contact with the single-headed hexagonal copper stud, the corresponding small board can also be directly cooled.

[0019] As a preferred technical solution of the present application, the cooling copper bar is provided with a stepped hole, a sealing ring is placed at the stepped surface of the stepped hole, the short copper tube is threadedly engaged with the stepped hole through the external thread at one end thereof and abuts against the sealing ring to form a sealing structure. The other end of the short copper tube has a stepped hole, and a corresponding sealing ring is also placed there. One end of the single-headed hexagonal copper stud is a small-diameter end, which is an external thread end, and this small-diameter end is threadedly engaged with the stepped hole of the short copper tube and abuts against the corresponding sealing ring; when the small-diameter end of the single-headed hexagonal copper stud is threadedly engaged with the short copper tube, the corresponding small board is also clamped and fixed. The other end of the single-headed hexagonal copper stud has a stepped hole, and a corresponding sealing ring is also placed there. The small-diameter end of another single-headed hexagonal copper stud is threadedly engaged with the stepped hole of the previous single-headed hexagonal copper stud and abuts against the corresponding sealing ring; when the two single-headed hexagonal copper studs are threadedly engaged, the corresponding small board is also clamped and fixed. For the single-headed hexagonal copper stud farthest from the camera housing, after the sealing ring is placed in its stepped hole, it is threadedly engaged with a flat-head screw. When mating, the hollow channel of the single-headed hexagonal copper stud is blocked, and the corresponding small board is also clamped and fixed during mating.

[0020] As a preferred technical solution of the present application, the water-cooled radiator is arranged at the abdomen of the unmanned aerial vehicle, and the water-cooled radiator is connected to the cooling channel of the cooling copper bar through a pipeline passing through the camera housing.

[0021] As a preferred technical solution of the present application, when installing multiple small boards in a circuit board, at least two cooling copper bars are symmetrically arranged on both sides of the corresponding small board to form a structure for stably supporting the corresponding small board.

[0022] As a preferred technical solution of the present application, a whole functional circuit board is arranged on the top wall and the front wall of the camera housing, and a functional circuit board composed of multiple small boards is arranged on the bottom wall of the camera housing; the left wall and the right wall of the camera housing are detachable side plates, and the front part of the side plate has heat dissipation holes; the rear wall of the camera housing has a large heat dissipation window.

[0023] As a preferred technical solution of the present application, the heat dissipation holes are round holes or fish-scale hole shapes.

[0024] For ease of understanding, the core design points of this solution are described as follows: a. Each functional circuit board is dispersed at the inner walls of the camera housing, and a spacing is formed between the functional circuit board and the inner wall of the camera. In this way, when the functional circuit board generates heat, the heat can be more evenly dispersed throughout the camera housing, and can dissipate through the spacing between the functional circuit board and the corresponding inner wall, and the blank space between adjacent functional circuit boards, and finally dissipate from the heat dissipation holes; b. The functional circuit board with less heat generation is directly set as a whole at the corresponding inner wall position, and the functional circuit board with more heat generation is disassembled into multiple small boards arranged at intervals. In this way, when the small boards arranged at intervals generate heat, the heat is more dispersed, and it is convenient for the heat to dissipate from the heat dissipation spacing between adjacent ones; c. The space between the small board and the corresponding inner wall is cooled intensively through the cooling copper bar. Through the butt joint of the short copper pipe and multiple single-headed hexagonal copper studs, the water can be extended to a more central position of the camera housing. Using the principle of rapid heat absorption and heat release of water can better cool the central part of the camera housing (even if the water cannot flow well in the short copper pipe and multiple single-headed hexagonal copper studs, it can still conduct heat exchange with the water in the cooling copper bar); In addition, since the single-headed hexagonal copper stud is directly in contact with the small board, it can also better cool the small board.

[0025] The utility model has the following advantages: By dispersing each functional circuit board to avoid heat concentration, replacing the individual ones with extremely serious abnormal heat generation with multiple small boards, and additionally cooling the small boards, good cooling inside the camera is achieved, and thus the camera can work for a long time.

[0032] The following further describes the present utility model in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following description.

[0033] It should be noted that the orientation or positional relationship indicated by "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the invention product is placed habitually during use, or the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that generally, multiple functional circuit boards are provided inside the camera housing. For example: First, the CCD, DSP, and power supply are concentrated on one circuit board, which is the single board; Second, the CCD is arranged on one board, and the DSP and power supply are concentrated on another board, which is the double board; Third, the CCD is arranged on one board, the DPS is arranged on one board, and the power supply is arranged on one board, which is the multi-board. However, regarding the number and size of the boards, the issues of interference and heat generation need to be fully considered, which is not something that ordinary enterprises can achieve. When a drone carries a camera for emergency rescue and other work, there are many functional modules inside this camera. When it works for a long time, the heat generated is difficult to solve by the internal structure layout of ordinary cameras. Therefore, the present solution is implemented through the following embodiments.

[0036] As Figures 1 - 5 shown, the camera heat dissipation structure for a drone proposed in this embodiment includes a camera housing and multiple functional circuit boards 10 arranged inside it. Heat dissipation holes 20 are opened on the camera housing;

[0037] The multiple functional circuit boards 10 are respectively arranged at the inner walls of the camera housing through support members, so that the multiple functional circuit boards 10 are dispersed; and a spacing is formed between the functional circuit boards 10 and the inner wall of the camera housing;

[0038] When each functional circuit board 10 generates heat, the heat is more evenly dispersed at various positions in the internal space of the camera housing, rather than concentrated at a certain position. Moreover, this structure is conducive to the heat escaping from the spacing between the functional circuit board 10 and the inner wall of the camera housing and from the blank area between the functional circuit boards, and finally escaping from the heat dissipation holes 20, and the dissipation effect is good.

[0039] Refer to Figure Figure 4 and Figure 5, inside the camera, there is a functional circuit board 10 with relatively low heat generation, and there is also a functional circuit board 10 with relatively high heat generation. This circuit board 10 with relatively high heat generation is formed by connecting multiple small boards 11 through cables. Both ends of the cable have plugs, and the plugs are inserted on the corresponding small boards 11;

[0040] For the functional circuit board 10 with relatively high heat generation, a plurality of corresponding small boards 11 are arranged in different equidistant planes parallel to the inner wall of the camera housing. A heat dissipation space is formed between the small boards 11 on adjacent equidistant planes, forming a structure to avoid heat concentration on one board. For example, at the lower inner wall of the camera housing, the corresponding small boards 11 are arranged in planes at different heights, with a spacing set between adjacent small boards 11, and there is a spacing between the lowermost small board 11 and the lower inner wall of the camera housing;

[0041] Since the circuit board 10 with relatively high heat generation is decomposed into multiple small boards 11 and arranged equidistantly in space, the heat generated is relatively uniform and will not concentrate in a certain place, facilitating heat dissipation.

[0042] Preferably, a whole functional circuit board 10 - that is, a board with relatively low heat generation - is provided at the top wall and the front wall of the camera housing; a functional circuit board 10 composed of multiple small boards 11 - that is, a circuit board with relatively high heat generation - is provided at the bottom wall of the camera housing. In addition, the left and right walls of the camera housing are detachable side plates, and the front part of the side plates has heat dissipation holes 20; the rear wall of the camera housing has a large heat dissipation window 10.

[0043] Refer to Figure Figure 3 and Figure 5 , a plurality of cooling copper bars 30 are fixed on the inner wall of the camera housing. The cooling copper bars 30 have cooling channels inside, and the cooling channels are connected to an external water-cooled radiator through pipes;

[0044] The plurality of small boards 11 in the functional circuit board 10 with relatively high heat generation are arranged in different equidistant planes parallel to the corresponding inner wall of the camera housing, which means that: in the direction from close to the inner wall to far from the inner wall, the small board 11 of the first layer is supported on the cooling copper bar 30 through a short copper pipe 31 and locked and fixed by a single-headed hexagonal copper stud 32. The small board 11 of the second layer is placed on the lower single-headed hexagonal copper stud 32 and locked and fixed by another single-headed hexagonal copper stud 32; multiple small boards 11 are placed and fixed in this way, and the small board 11 farthest from the inner wall of the camera housing is locked and fixed by a flat head screw 33;

[0045] And, the single-headed hexagonal copper stud 32 is a hollow stud;

[0046] In the direction from close to the inner wall to far from the inner wall: a short copper pipe 31 is screwed onto the cooling copper bar 30 - multiple single-headed hexagonal copper studs 32 are serially threaded on the short copper pipe 31 - a flat head screw 33 is screwed on;

[0047] When water circulates along the cooling channels of the cooling copper bar 30, the cooling copper bar 30 cools the area of the corresponding small plate 11 and the inner wall of the camera housing; when water circulates along the cooling channels of the cooling copper bar 30, a part of the water enters the short copper pipe 31 and the hollow single-headed hexagonal copper stud 32, cooling the heat dissipation space between adjacent small plates 11. Since the small plate 11 is in direct contact with the single-headed hexagonal copper stud 32, the corresponding small plate 11 can also be directly cooled.

[0048] Furthermore, to achieve good sealing: a stepped hole is provided in the cooling copper bar 30, and a sealing ring is placed at the stepped surface of the stepped hole. The short copper pipe 31 is threadedly engaged with the stepped hole through the external thread at one end thereof and abuts against the sealing ring to form a sealing structure. The other end of the short copper pipe 31 has a stepped hole, and a corresponding sealing ring is also placed at this stepped hole. One end of the single-headed hexagonal copper stud 32 is a small-diameter end, which is an external thread end. The small-diameter end is threadedly engaged with the stepped hole of the short copper pipe 31 and abuts against the corresponding sealing ring; when the small-diameter end of the single-headed hexagonal copper stud 32 is threadedly engaged with the short copper pipe 31, the corresponding small plate 11 is also clamped and fixed. The other end of the single-headed hexagonal copper stud 32 has a stepped hole, and a corresponding sealing ring is also placed at this stepped hole. The small-diameter end of another single-headed hexagonal copper stud 32 is threadedly engaged with the stepped hole of the previous single-headed hexagonal copper stud 32 and abuts against the corresponding sealing ring; when the two single-headed hexagonal copper studs 32 are threadedly engaged, the corresponding small plate 11 is also clamped and fixed. For the single-headed hexagonal copper stud 32 farthest from the camera housing, after the sealing ring is placed in its stepped hole, it is threadedly engaged with a flat head screw 33. During the engagement, the hollow channel of the single-headed hexagonal copper stud 32 is blocked, and the corresponding small plate 11 is also clamped and fixed during the engagement.

[0049] In this embodiment, the support member for the function unit 10 with less heat generation is a copper bolt rod.

[0050] In this embodiment, the water-cooled radiator is provided at the abdomen of the unmanned aerial vehicle, and the water-cooled radiator is connected to the cooling channels of the cooling copper bar 30 through a pipeline passing through the camera housing.

[0051] In this embodiment, when installing the multiple small plates 11 of the function circuit board 10 with more heat generation, at least two cooling copper bars 30 are symmetrically arranged on both sides of the corresponding small plates 11 to form a structure for stably supporting the corresponding small plates 11. Of course, for better cooling effect, more cooling copper bars 30 can also be provided.

[0052] In this embodiment, the heat dissipation holes 20 are round holes or fish-scale hole shapes.

[0053] The principle of the camera heat dissipation structure of the present utility model is as follows: First, a plurality of functional circuit boards 10 are dispersed at the inner walls of the camera housing, and a spacing is formed between the functional circuit boards 10 and the inner wall of the camera. In this way, when the functional circuit boards 10 generate heat, the heat can be more evenly dispersed throughout the camera housing. The cooling water flowing in from the large heat dissipation hole 40 flows through the spacing between the functional circuit board 10 and the corresponding inner wall and the blank space between adjacent functional circuit boards, and finally is discharged from the heat dissipation hole 20. Second, the functional circuit boards 10 with less heat generation are directly arranged as a whole at the corresponding inner wall positions, and the functional circuit boards 10 with more heat generation are disassembled into a plurality of small boards 11 arranged at intervals. In this way, when the small boards 11 arranged at intervals generate heat, the heat is more dispersed, and it is convenient for the heat to dissipate from the heat dissipation spacing between adjacent small boards 11. Third, the space between the small board 11 and the corresponding inner wall is cooled intensively through the cooling copper bar 30. Of course, according to needs, the space between other functional circuit boards 10 and the corresponding inner wall can also be cooled. Through the butt joint of the short copper pipe 31 and a plurality of single-head hexagonal copper studs 32, the water can be extended to a more central position of the camera housing. By using the principle that water absorbs and releases heat quickly, the central part of the camera housing can be better cooled (even if the water cannot flow well in the short copper pipe 31 and a plurality of single-head hexagonal copper studs 32, it can still exchange heat with the water in the cooling copper bar 30). In addition, since the single-head hexagonal copper stud 32 is directly in contact with the small board 11, the small board 11 can also be better cooled.

[0054] It should be noted that the water-cooled radiator can adopt a general design, such as a structure in which a fan cools the pipeline of the heat exchanger.

[0055] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
