Description

Technical Field

[0001] The utility model relates to the technical field of camera devices, in particular to a camera that is conducive to heat dissipation. Background Art

[0002] A camera is a relatively commonly used monitoring camera device. During operation, a camera will generate a certain amount of heat. Especially for a multi-lens camera with multiple lenses, the more lenses there are, the greater the heat generation, resulting in a heat problem for the camera. Secondly, in order to be compatible with more usage scenarios, current cameras are developing towards small size and high performance. The internal space is compressed, the components are arranged compactly, and the heat dissipation space is small, further exacerbating the heat problem of the camera.

[0003] The heat generated by the camera will not only affect the working performance of the internal components of the camera and reduce the service life of the components; when the temperature difference between the inside and the external environment is large, it will also cause the camera lens to fog up, greatly affecting the actual use effect of the camera. Most cameras on the current market use the heat conduction of metal to solve the heat problem. A metal shell is adopted at the heat source and heat dissipation teeth are designed for heat conduction to conduct the internal temperature to the surface, but this will cause the surface temperature of the metal shell to be too high, and there are safety problems such as being scalded. For the fogging problem, most current cameras solve it by placing desiccant inside. Although it can prevent fogging, the desiccant has a service life and cannot solve the fogging problem in the long term. Summary of the Invention

[0004] The purpose of the utility model is to provide a camera that is conducive to heat dissipation to solve the above-mentioned heat generation and fogging problems of the camera.

[0005] To achieve the above purpose, the technical solution of the utility model is: a camera that is conducive to heat dissipation, including a first housing assembly and a second housing assembly arranged opposite to each other. The first housing assembly is provided with a receiving cavity for installing a control board. A fan assembly is also provided between the first housing assembly and the second housing assembly. An air outlet is also provided, and the air outlet is located at the air outlet end of the fan assembly. The fan assembly is used to discharge the heat in the receiving cavity to the outside of the camera through the air outlet.

[0006] In one embodiment, the fan assembly is provided with an air inlet. The control board is arranged between the fan assembly and the second housing assembly. There is a certain gap between the control board and the second housing. This gap forms an air inlet passage. And the surface of the control board facing the air inlet passage is provided with a control chip. The control board is also provided with a first ventilation opening corresponding to the air inlet. Thus, the air inlet passage, the first ventilation opening, the fan assembly, and the air outlet form a first heat dissipation passage, and the heat in the receiving cavity is discharged to the outside of the camera by means of the first heat dissipation passage.

[0007] In one embodiment, it further includes a camera assembly disposed in the accommodating cavity. Define the direction in which the first housing assembly is mounted relative to the second housing assembly as the first direction. The camera assembly is located in the first direction of the control board. A second ventilation opening is provided at the air outlet end between the accommodating cavity and the fan assembly. The air inlet channel is formed in the accommodating cavity. Thus, the air inlet channel, the first ventilation opening, the fan assembly, the second ventilation opening, and the accommodating cavity form a second heat dissipation channel, and the heat in the accommodating cavity circulates inside the camera by means of the second heat dissipation channel.

[0008] In one embodiment, the fan assembly includes a fan, the air outlet is provided in the axial direction of the fan, and the second ventilation opening is provided in the radial direction of the fan.

[0009] In one embodiment, the camera assembly includes at least one lens module and a mounting plate for mounting the lens module. The mounting plate divides the accommodating cavity into a first accommodating cavity for mounting the lens module and a second accommodating cavity for mounting the control board. A third ventilation opening is further provided between the first accommodating cavity and the second accommodating cavity. The second ventilation opening is provided between the second accommodating cavity and the fan assembly. A fourth ventilation opening is formed between the circumferential edge of the control board and the second housing assembly. The fan assembly includes a fan. In the radial direction of the fan, the third ventilation opening is closer to the rotation axis of the fan than the fourth ventilation opening. Thus, the part of the second heat dissipation channel located in the second accommodating cavity extends reciprocally on both sides of the control board.

[0010] In one embodiment, the fan assembly further includes a first support member connected to the first housing assembly and a second support member connected to the second housing assembly. The fan is mounted between the first support member and the second support member. The first support member is located at the air outlet end of the fan assembly. The air inlet is provided at the end of the second support member. The second ventilation opening is provided between the first support member and the second support member. The third ventilation opening is provided on the side surface of the second support member.

[0011] In one embodiment, the lens modules are circumferentially arranged on the outer peripheral side of the fan assembly. On the circumference of the fan assembly, flow guide plates are provided on both sides of the lens modules.

[0012] In one embodiment, the second housing assembly includes a lower cover made of a heat-conducting material. The lower cover is located on one side of the control board and adjacent to the control board. Thus, the lower cover forms a third heat dissipation channel, and the heat in the accommodating cavity is discharged to the outside of the camera by means of the third heat dissipation channel.

[0013] In one embodiment, the lower cover is provided with a ventilation valve.

[0014] In one embodiment, the first housing assembly includes a ball cover and a decorative cover. The air outlet includes a first air outlet provided on the blower assembly, a second air outlet provided on the ball cover, and a third air outlet provided on the decorative cover. The decorative cover is disposed on the ball cover and covers the second air outlet.

[0015] In one embodiment, a waterproof and breathable membrane is provided between the ball cover and the decorative cover.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By providing a blower assembly, the heat generated in the accommodation cavity is discharged outside the camera through the air outlet, which helps to dissipate the heat of the camera, prevent the internal temperature of the camera from being too high, and also prevent fogging due to excessive temperature difference between the inside and outside of the camera, ensuring the normal operation of the camera.

[0018] 2. The first heat dissipation channel can discharge the heat in the accommodation cavity outside the camera, and the second heat dissipation channel can form an air circulation inside the accommodation cavity, so that the heat generated by the heat sources (CPU and lens module) converges with the air flow in the first heat dissipation channel during the circulation process, timely reducing the temperature at the heat source and further preventing the internal temperature of the camera from being too high.

[0019] 3. The lower shell of the second housing assembly is disposed on the side of the control board facing the second direction and adjacent to the control board, so that the heat generated by the control chip on the control board facing the second direction can be conducted outside the camera, and cooperate with the heat convection formed by the blower assembly through heat conduction to form an effective heat dissipation structure, further preventing the internal temperature of the camera from being too high.

[0029] To further illustrate each embodiment, the present utility model provides drawings. These drawings are part of the disclosure of the present utility model, which are mainly used to illustrate the embodiments and can be used to explain the operation principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] Refer to Figures 1 to 3 As shown, the present utility model discloses a camera that is conducive to heat dissipation, including a first housing assembly 1 and a second housing assembly 2 that are oppositely arranged. The first housing assembly 1 is provided with an accommodation cavity 100 for installing the control board 3. A fan assembly 4 is also provided between the first housing assembly 1 and the second housing assembly 2. An air outlet 5 is further provided, and the air outlet 5 is located at the air outlet end of the fan assembly 4. The fan assembly 4 is used to discharge the heat in the accommodation cavity 100 to the outside of the camera through the air outlet 5. By providing the fan assembly 4, the heat generated in the accommodation cavity 100 is discharged to the outside of the camera through the air outlet 5, which helps to dissipate the heat of the camera, prevent the internal temperature of the camera from being too high, and also prevent fogging due to too large a temperature difference between the inside and outside of the camera, ensuring the normal operation of the camera.

[0031] Refer to Figures 1 to 7As shown, the camera in this example is a multi-lens multi-directional camera, which includes a plurality of lens modules 61. The plurality of lens modules 61 are distributed on the circumference of the camera to achieve multi-directional monitoring. The lens module 61 faces the spherical cover 11 of the first housing assembly 1, and the transparent spherical cover 11 forms the viewing window of the lens module 61. In other embodiments, the camera may also be a single-lens camera, and the single-lens camera is only provided with one lens module 61.

[0032] In addition to the spherical cover 11, the first housing assembly 1 further includes an annular outer cover portion 12 provided outside the spherical cover 11. The spherical cover 11 is made of a transparent material to facilitate light to enter the camera and be captured by the lens module. The second housing assembly 2 includes a lower cover 21, and a receiving cavity 100 is formed in the cavity formed by the splicing of the first housing assembly 1 and the second housing assembly 2. A control board 3 and a camera assembly 6 are provided in the receiving cavity 100. The camera assembly 6 includes a lens module 61 and a mounting plate 62. The lens modules 61 are arranged at circumferential intervals around the fan assembly 4 on the mounting plate 62. The direction in which the first housing assembly 1 is mounted relative to the second housing assembly 2 is the first direction, and the opposite direction is the second direction, that is Figure 2 the direction X1 is the first direction, and the direction X2 is the second direction. The mounting plate 62 divides the receiving cavity 100 into a first receiving cavity 101 and a second receiving cavity 102. The first receiving cavity 101 is located in the first direction X1 relative to the second receiving cavity 102. The lens module 61 of the camera assembly 6 is provided in the first receiving cavity 101, and the control board 3 is provided in the second receiving cavity 102.

[0033] Refer to Figures 3 to 5 As shown, the fan assembly 4 is provided with an air inlet 41. The control board 3 is provided in the second receiving cavity 102 and is located between the fan assembly 4 and the lower shell 21 of the second housing assembly 2. There is a certain gap between the control board 3 and the lower shell 21 of the second housing 2, and this gap forms an air inlet passage. And the surface of the control board 3 facing the air inlet passage is provided with a control chip. The control board 3 is also provided with a first ventilation opening 31 corresponding to the air inlet 41. Thus, the air inlet passage, the first ventilation opening 31, the fan assembly 4 and the air outlet 5 form a first heat dissipation passage 10, and the heat in the receiving cavity 100 is discharged outside the camera through the first heat dissipation passage 10. A large amount of heat is generated when the control chip is running, which is also the main heat source of the camera. Therefore, by connecting the side of the control board 3 where the control chip is located to the air inlet 41 of the fan assembly 4, more specifically, the surface of the control board 3 in the first direction abuts against the air inlet end of the fan assembly 4, and the first ventilation opening 31 of the control board 3 is correspondingly arranged with the air inlet 41 of the fan assembly 4. Thus, when the fan assembly 4 works, it has a large suction effect on the gas in the air inlet passage, can draw away the heat generated by the control chip at the air inlet passage, and is discharged outside the camera through the air outlet 5 provided at the air outlet end of the fan assembly 4, greatly reducing the temperature inside the camera and having a remarkable effect on preventing the camera from overheating inside.

[0034] Refer to Figures 3 to 5 As shown, the camera assembly 6 is located in the first direction of the control board 3. A second ventilation opening 42 is provided at the air outlet end between the accommodation cavity 100 and the fan assembly 4. An air inlet passage is formed in the accommodation cavity 100. Thus, the air inlet passage, the first ventilation opening 31, the fan assembly 4, the second ventilation opening 42, and the accommodation cavity 100 form a second heat dissipation channel 20. The heat in the accommodation cavity 100 circulates in the camera by means of the second heat dissipation channel 20. The lens module 61 of the camera assembly 6 also generates a certain amount of heat during operation, which is another heat source of the camera. When the fan assembly 4 is operating, since the air at the air inlet passage is sucked by the fan assembly 4 to form a low pressure, when the low pressure is just formed, the air pressure in other parts of the accommodation cavity 100 (the parts of the first accommodation cavity 101 and the second accommodation cavity 102 in the first direction of the control board 3) is relatively high. Thus, an air flow is formed from the first accommodation cavity 101 towards the second accommodation cavity 102 direction, thereby reducing the air pressure in the first accommodation cavity 101. Also, since there is a second ventilation opening 42 between the first accommodation cavity 101 and the air outlet end of the fan assembly 4, in addition to a part of the gas at the air outlet end of the fan assembly 4 being discharged to the outside of the camera through the air outlet 5, there is also a part of the gas that enters the first accommodation cavity 101 through the second ventilation opening 42. Thus, a circulating air flow is formed in the air inlet passage - the air inlet 41 of the fan assembly 4 - the second ventilation opening 42 - the first accommodation cavity 101 - the part of the second accommodation cavity 102 in the first direction of the control board 3 - the air inlet passage. The passage through which the circulating air flow flows is the second heat dissipation channel 20. The second heat dissipation channel 20 will pass through the first accommodation cavity 101 where the camera assembly 6 is provided. Therefore, it can take away the heat generated by the lens module 61 and achieve the purpose of cooling the lens module 61. Since a part of the first heat dissipation channel 10 and the second heat dissipation channel 20 in the air inlet passage and the fan assembly 4 overlap, that is, the discharged air flow of the first heat dissipation channel 10 and the circulating air flow of the second heat dissipation channel 20 will mix, and the heat generated by the lens module 61 will be discharged to the outside of the camera during this mixing process.

[0035] The fan assembly 4 includes a fan 43. The air outlet 5 is arranged axially of the fan 43, and the second ventilation opening 42 is arranged radially of the fan 43. In this way, most of the air flow discharged by the fan 43 can be discharged to the outside of the camera through the air outlet 5, and a relatively small part of the air flow enters the first accommodation cavity 101 through the second ventilation opening 42 for circulation. In this way, it can ensure that most of the heat is discharged to the outside of the camera and keep the camera within a relatively low temperature range.

[0036] Refer to Figures 3 to 5As shown, in order to make the circulating air flow in the second heat dissipation channel 20 more stable, a third ventilation opening 44 is further provided between the first accommodating cavity 101 and the second accommodating cavity 102. A fourth ventilation opening 32 is formed between the circumferential edge of the control board 3 and the second housing assembly 2. In the radial direction of the fan 43, the third ventilation opening 44 is closer to the rotation axis of the fan 43 than the fourth ventilation opening 32. Thus, the part of the second heat dissipation channel 20 located in the second accommodating cavity 102 extends reciprocally on both sides of the control board 3. Such a design can extend the length of the second heat dissipation channel 20 and enable the gas flow at various positions inside the camera, preventing the gas in some areas from not flowing for a long time and causing the temperature to rise or the evaporated water vapor to accumulate.

[0037] Refer to Figures 3 to 5 As shown, the fan assembly 4 further includes a first support member 45 connected to the first housing assembly 1 and a second support member 46 connected to the second housing assembly 2. The fan 43 is installed between the first support member 45 and the second support member 46. The first support member 45 is located at the air outlet end of the fan assembly 4. The air inlet 41 is provided at the end of the second support member 46. The second ventilation opening 42 is provided between the first support member 45 and the second support member 46. The third ventilation opening 44 is provided on the side surface of the second support member 46. The fan 43 is installed between the first support member 45 and the second support member 46 and is fixed by the limiting effect of the first support member 45 and the second support member 46. Since the lens module 61 is circumferentially arranged on the outer peripheral side of the fan assembly 4, the second ventilation opening 42 is also circumferentially arranged along the outer peripheral side of the fan assembly 4. In this example, the second ventilation opening 42 is formed by a circumferential arrangement of a plurality of spaced openings. In other embodiments, the second ventilation opening 42 may also be a continuous annular opening.

[0038] Since both the second ventilation opening 42 and the third ventilation opening 44 are provided on the fan assembly 4, that is, they are relatively close to the rotation axis of the fan 43, it may cause the flow range of the circulating air flow in the second accommodating cavity 102 along the radial direction of the fan 43 to be small. Also, since the second ventilation opening 42 is provided in the radial direction of the fan 43, the air flow flowing out from the second ventilation opening 42 is radially outward along the fan 43, that is, towards the edge of the first housing assembly 1. When the circulating air flow hits the inner wall of the dome 11, it will flow in the first direction and, under the action of the flow guiding plates 63 on both sides of the lens module 61, flow radially inward along the fan 43. Thus, the circulating air flow can flow through the area where the lens module 61 is located, achieving the purpose of cooling the lens module 61.

[0039] Refer to Figure 6As shown in the figure, the first housing assembly 1 further includes a decorative cover 13 provided on the globe cover 11. The air outlet 5 includes a first air outlet 51 provided on the fan assembly 4, a second air outlet 52 provided on the globe cover 11, and a third air outlet 53 provided on the decorative cover 13. More specifically, the first air outlet 51 is provided on the first support member 45 of the fan assembly 4. The decorative cover 13 is covered on the globe cover 11 and covers the second air outlet 52. Thus, the first air outlet 51, the second air outlet 52, the third air outlet 53, and the gaps between the three form an air outlet passage, and the gas discharged by the fan assembly 4 is discharged outside the camera through this air outlet passage. The first air outlet 51, the second air outlet 52, and the third air outlet 53 are arranged in a staggered manner, which can not only ensure that the gas from the fan assembly 4 is smoothly discharged outside the camera, but also prevent the water vapor outside the camera from entering the camera through the air outlet 5.

[0040] In order to further prevent water vapor from entering the camera through the air outlet 5, a waterproof breathable film (not shown in the figure) is provided between the globe cover 11 and the decorative cover 13. The material and waterproof breathable principle of the waterproof breathable film are prior arts and will not be elaborated here.

[0041] The lower cover 21 of the second housing assembly 2 is made of a heat-conducting material. The lower cover 21 is located on one side of the control board 3 and adjacent to the control board 3. Thus, the lower cover 21 forms a third heat dissipation channel 30, and the heat in the accommodation cavity 100 is discharged outside the camera by means of the third heat dissipation channel 30. More specifically, the heat generated by the control chip on the control board 3 in the second accommodation cavity 102 forms heat conduction through the lower cover 21, and then is discharged outside the camera by the lower housing 21 with better heat conduction performance. In order to further improve the heat dissipation performance of the lower cover 21, the lower cover 21 is provided with a ventilation valve. The ventilation valve is a one-way valve, and the gas can only pass through the ventilation valve and be discharged from the inside of the camera to the outside of the camera, so as to prevent the external water vapor from entering the camera through the ventilation valve.

[0042] In this example, the control board 3 is a circuit PCB board, and the control chip is arranged on the circuit PCB board and serves as the CPU of the circuit board.

[0043] Refer to Figure 7 As shown in the figure, the heat dissipation path of the present utility model is as follows, where the direction indicated by the arrow is the direction of heat transfer:

[0044] 1. Part of the heat generated by the control chip of the control board 3 is dissipated through the lower cover 21 and the ventilation valve;

[0045] 2. The fan assembly 4 operates, and the heat generated by the control chip enters the fan assembly 4 through the air inlet 41. A part of the gas discharged from the air outlet end of the fan assembly 4 is discharged outside the camera through the air outlet 5; a part flows to each lens module 61 under the guidance of the second ventilation port 42, then flows to the space between the control board 3 and the mounting plate 62 through the third ventilation port 44, and finally forms a circulating air flow by flowing through the fourth ventilation port 32 to the air inlet channel between the control board 3 and the lower housing 21.

[0046] Under the action of the heat convective heat dissipation at the air outlet 5 of the dome 11 and the heat conduction heat dissipation of the lower housing 21, the heat inside the camera has been greatly reduced; the remaining heat will also gradually decrease during the flowing process, effectively solving the problem of heat generation of the multi-camera; when the external environmental temperature is too low and the internal temperature of the camera is relatively high, and the residual moisture inside volatilizes (the camera has good sealing performance, and the moisture mainly remains during installation and enters through the air permeable valve and waterproof breathable film), it will cause the lens to fog up. At this time, the air flow driven by the fan 43 will play a role in defogging and dehumidifying, solving the problem of lens fogging of the camera.

[0047] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that the remaining parts not described are the prior art, and various changes made to the present invention in form and details without departing from the spirit and scope of the present invention defined by the appended claims all fall within the protection scope of the present invention.
