Description

[Technical Field]

[0001] The present invention relates to a pan head camera device, and more particularly to cooling of a base portion that connects to an external device. [Background technology]

[0002] It has been known that conventional camera pan head devices use sealed structures to prevent dust and are subject to the heat of sunlight, which can cause the temperature inside the device to rise. The circuit boards placed inside the device require cooling, and some devices have a heat dissipation structure. For example, Patent Document 1 discloses a technology that uses a light-shielding member to block the effects of sunlight, places a heat sink inside the light-shielding member and outside a sealed component that contains a heat-source board, and cools the heat-source board by bringing the heat sink into contact with the heat-source board.

[0012] As shown in Figure 2, the pan head camera device 100 is configured to include a camera unit 200, a swivel unit 300 that holds the camera unit 200, and a base unit 10 that holds the swivel unit 300. The swivel unit 300 moves the camera unit 200 that it holds in a tilt direction 301 and a pan direction 302. Here, the tilt direction 301 is the direction of rotation around the x-axis, and the pan direction 302 is the direction of rotation around the z-axis. The base unit 10 is installed on an installation surface such as the ground, and serves as a seat for the pan head camera device 100. The base unit 10 connects the swivel unit 300 to the installation surface.

[0013] 3 and 4, the base unit 10 has a base 1, a case unit 2, and a bottom plate 4. The base unit 10 also has a shading member 5 that is held at a certain distance from the base 1 and blocks sunlight, a hose unit 6 that protects cables and the like connected to external devices, and a lid unit 7 that protects cable connectors and the like. The case unit 2 is contained within and held in the base 1, and holds a communication and power cable 22 from the swivel unit 300 via a connector 21. The case unit 2 has a replaceable replacement unit 3.

[0014] The base 1 is made of metal, and more preferably aluminum. As shown in Fig. 5, the base 1 has a convex portion 11 on its inner wall that protrudes inward from the inner wall. The base 1 may also have a convex portion 12 between the outer wall and the light-shielding member 5 that protrudes outward from the outer wall.

[0015] As shown in FIG. 4, the case part 2 is contained in and held by the base 1, and holds a communication and power cable 22 from the swivel part 300 via a connector 21.

[0016] Fig. 6 is a perspective cross-sectional view taken along a plane perpendicular to the x-axis, showing the insertion of the replacement unit 3 into the case unit 2. Fig. 7 is an exploded perspective view of the replacement unit 3. As shown in Figs. 4, 6 and 7, part of the case unit 2 is the replacement unit 3 that is inserted into and removed from the base unit 10. The replacement unit 3 is contained within the base 1 and is held by a structure within the case unit 2 when the pan head camera device 100 is in operation.

[0017] The exchange unit 3 has an IC board 311 and an optical communication board 312 as information processing boards. The exchange unit 3 also has a fan 32, which is an axial fan, as board cooling means for cooling the IC board 311 and the optical communication board 312, and an internal connector 33 that connects a cable from the IC board 311 to the connector 22 of the case unit 2. The exchange unit 3 also has an external connector metal plate 34 as an external connector unit, an IC metal plate 35, an optical communication metal plate 36, and a holding metal plate 37. The cover unit 7 is penetrated by a cable connecting to an external device and covers the external connector metal plate 34 as the external connector unit. The IC metal plate 35 holds the IC board 311. The optical communication metal plate 36 holds the optical communication board 312. The holding metal plate 37 holds the fan 32 and the internal connector 33. That is, the fan 32 is held on the same surface as the surface of the exchange unit 3 on which the internal connector 33 is arranged.

[0018] An IC 3111 as an integrated circuit is mounted on IC board 311 as a first board, which processes image capture information from camera unit 200 as an image signal processing unit and performs communication processing with external devices as a communication processing unit. Part of the communication processing is performed by optical connector unit 3121 as optical communication processing means disposed on optical communication board 312 as a second board.

[0019] The IC 3111 and the optical connector unit 3121 are provided with a heat sink 3112 and a heat sink unit 3122 that diffuse and dissipate heat generated from the IC 3111 and the optical connector unit 3121. In this embodiment, the heat sink 3112 and the heat sink unit 3122 are used for the IC 3111 and the optical connector unit 3121, but it is sufficient if the heat from the heat source is diffused after being transferred, and the heat may be transferred to the exchange unit 3 using materials or means such as copper plate or graphite sheet.

[0020] 6 , the external connector metal plate 34 holds a plurality of external connectors 38 to which cables for connecting to external devices are attached. The external connectors 38 are connected to the IC board 311 and the optical communication board 312 by cables. The external connector metal plate 34 is fastened to the holding metal plate 37 with screws. The IC metal plate 35 and the optical communication metal plate 36 are also fastened to the holding metal plate 37 with screws. These components form the skeletal structure of the exchange unit 3. The IC board 311, the optical communication board 312, and the corresponding heat sink 3112 and heat sink part 3122 are housed within the exchange unit 3.

[0021] As shown in Figures 1, 4 and 6, the case part 2 including the replacement part 3 has an intake port 371 through which cooling air flows into the case part 2 to cool the IC board 311 and the optical communication board 312, and an exhaust port 24 through which cooling air flows out of the case part 2.

[0022] The exhaust port 24 is disposed near the external connector metal plate 34 in the case part 2. The exhaust port 24 is disposed on a surface different from the surface direction of the external connector metal plate 34. In this embodiment, the exhaust port 24 is disposed on a surface perpendicular to the surface direction of the external connector metal plate 34 (direction perpendicular to the y-axis).

[0023] The intake port 371 is disposed farther from the external connector metal plate 34 than the exhaust port 24, which is located near the external connector metal plate 34 in the case unit 2. At least one of the IC board 311 and the optical communication board 312 is disposed between the exhaust port 24 and the intake port 371. The intake port 371 is disposed in a direction perpendicular to the direction of gravity (z-axis). The surfaces of the IC board 311 and the optical communication board 312 in the exchange unit 3 are disposed in a plane parallel to the direction of gravity (z-axis).

[0024] 4 and 7 , the fan 32 has an air intake port 321 through which air is drawn in by the fan 32, and an air outlet port 322 through which air is discharged by the fan 32. The fan 32 is disposed on the outside of the replacement unit 3, which is the outside of the holding metal plate 37, on a surface 372 of the holding metal plate 37 that faces the external connector metal plate 34 with the components housed in the replacement unit 3 in between. The holding metal plate 37 has an air intake port 371 on its surface 372 that supplies air generated by the fan 32 into the replacement unit 3. The fan 32 is attached to the replacement unit 3 by aligning the air intake port 371 of the case unit 2 with the air outlet port 322 of the fan 32, and by arranging the air intake port 321 facing the inner wall surface of the base 1.

[0025] On each surface of the exchange unit 3, the fan 32, the internal connector 33, and the air intake 371 are attached to the same surface, that is, the surface facing the external connector metal plate 34. That is, the exchange unit 3 has the fan 32, the internal connector 33, and the air intake 371 arranged on the surface 372. Therefore, the IC board 311 and the optical communication board 312 are arranged between the external connector metal plate 34 and the fan 32.

[0026] 8 is a side cross-sectional view of the inside of base 10 as seen from the y-axis direction. As shown in Fig. 8, IC 3111 and optical connector 3121, which are heat sources, as well as heat sink 3112 and heat sink 3122, are arranged on projection surface 322a on the hollow circle, which is air outlet 322 of fan 32.

[0027] 6, the insertion direction in which the replacement unit 3 is attached to the case unit 2 contained in the base unit 10 is direction 3a, which is the direction from the external connector metal plate 34 to the internal connector 33. Also, as shown in FIG. 4, when the replacement unit 3 is attached to the case unit 2, the connector 21 and the internal connector 33 are connected.

[0028] As shown in FIGS. 1, 4, and 5, the base 10 forms a sealed space with the base 1, the external connector metal plate 34 that is part of the replacement unit 3, and the bottom plate 4. Because the case 2 is enclosed within the base 10, the exhaust port 24 and the intake port 371 of the case 2 are located within the sealed space of the base 10. As a result, as shown in FIG. 1, airflow 81 discharged by the fan 32 first passes through spaces 86 and 87 within the case 2. The air that has passed through spaces 86 and 87 passes through the exhaust port 24 as air 84 and heads toward the outside of the case 2. Next, the air that has passed through the exhaust port 24 passes outside the case 2 and within the base 10 as air 83. The air that has passed outside the case 2 and within the base 10 is again drawn into the fan 32 as air 82. In this manner, circulation paths 88 and 89 are formed within the base 10. The sealed space of the base part 10 may be formed by the base 1 and the lid part 7.

[0029] 7, camera unit 200 has camera 201 as an imaging device that captures an image of a subject, and lens 202, which is an optical system attached to camera 201. Camera 201 and lens 202 are housed and held in a substantially airtight camera case 206 made up of metal sheet 203 and glass window 204. Note that the term "sealed" is used to include "substantially airtight."

[0030] Camera 201, to which lens 202 is attached, captures an image of a subject through glass window 204. Camera unit 200 also has a light shielding plate 205 arranged on the outside of metal sheet metal 203 of camera case 206 at a fixed distance from the top plate of metal sheet metal 203. Light shielding plate 205 blocks light from sunlight. Camera unit 200 can protect the camera 201 and lens 202 inside and improve environmental resistance by suppressing the effects of rain and wind through its nearly sealed structure and by suppressing the effects of sunlight through light shielding plate 205.

[0031] 2 has drive mechanisms such as motors, gears, and belts (not shown) inside for panning and tilting, and a drive board (not shown) controls the position and speed of the operations. The rotation unit 300 causes the camera unit 200 to perform panning and tilting operations, changing the direction in which the camera unit 200 takes pictures.

[0032] Next, with reference to FIGS. 1 to 9, the operation and effect of improving the cooling performance inside the substantially sealed base 10 according to the first embodiment of the present invention will be described.

[0033] The camera platform camera device 100 according to this embodiment is intended for outdoor installation, and therefore is required to be robust, have a long product life, and be capable of use in harsh environments. With the recent trend toward higher resolution images and increased capacity and faster communication speeds, the IC 3111 becomes a heat source and generates high heat. Furthermore, as part of the optical communication processing is performed by the optical communication board 312 as a means of achieving high-speed communication, the optical communication board 312 also generates high heat as a heat source. Furthermore, considering dust resistance and outdoor use, the base 1 covers the IC board 311 and the optical communication board 312, suppressing the heat dissipation from the IC board 311 and the optical communication board 312 by the fan 32, necessitating improved cooling capacity. Furthermore, improved cooling capacity is required to extend the life of the components mounted on the IC board 311 and the optical communication board 312. To maintain a long product life, the case 2 must include a replacement part 3 to facilitate easy replacement and maintainability.

[0034] As shown in FIG. 1 , the camera platform 100 includes a fan 32 to generate an airflow within the base 10. The camera platform 100 also includes an air intake 371 and an air exhaust 24 in the case 2, which guide an airflow 81 into the case 2, thereby cooling the IC board 311 and the optical communication board 312 arranged within the case 2. The airflow generated by the fan 32 flows along the inner wall of the base 1, efficiently promoting heat exchange between the outside air outside the base 1 and the air 8 inside the base 1 via the base 1, thereby improving cooling capacity. For this reason, the base 1 is preferably made of a material with high thermal conductivity, such as metal. This reduces the temperature difference between the air inside and outside the base 1. Furthermore, the convex portion 11 on the inner wall of the base 1 increases the surface area of ​​the inner wall of the base 1, thereby improving heat transfer performance with the air 83 flowing along the inner wall of the base 1 by the fan 32. In addition, by placing the shading member 5 shown in Figure 3 at a certain distance from the base 1, the temperature rise of the base 1 itself due to the influence of solar radiation is suppressed, and air 82 and air 83 flowing along the inner wall of the base 1 can exchange heat with the outside air temperature.

[0035] 1, the air outlet 322 of the fan 32 is aligned with the air intake 371 so that the air from the fan 32 is blown onto the IC board 311 and the optical communication board 312. This allows for efficient cooling by taking advantage of the directionality of the airflow 81 with strong local static pressure, which is a characteristic of the air outlet 322 of the fan 32, which is an axial fan. This increases the flow rate toward the object to be cooled, thereby improving the heat transport capacity from the object to be cooled to the cooling air.

[0036] 8, the IC 3111, heat sink 3112, optical connector 3121, and heat sink 3122 are arranged on the projection surface 322a (aperture projection) of the air outlet 322 of the fan 32. At least one of the heat sources is arranged on the aperture projection. This allows air to be sent to a small space such as a heat sink, improving cooling capacity. In addition, since most of the IC board 311 and optical communication board 312 are arranged on the projection surface 322a, heat dissipation from the board itself is promoted, further improving cooling efficiency.

[0037] 1, by arranging the air intake port 321 of the fan 32 on the inner wall side of the base 1, it is possible to utilize the characteristic of the air intake port 321 of the fan 32, which is an axial fan, to draw air evenly from a wide range. This allows air 82 to flow evenly through the inner wall portion of the base 1, which has a large area, and air 8 that has exchanged heat with outside air through the base 1 can be drawn in from various directions. This makes it possible to keep the air temperature at the air intake port 321 of the fan 32 low and evenly, improving cooling capacity.

[0038] As shown in FIG. 1 , in this embodiment, a sealed space is formed by the base 1, the external connector metal plate 34, and the bottom plate 4, or by the base 1, the lid 7, and the bottom plate 4. The case 2 is disposed within the base 10 and has a duct shape with the air intake 371 and the air exhaust 24. As a result, air 84 passing through the inside of the case 2 passes outside the case 2 and inside the base 1 (air 83), and is then guided back into the case 2 by the fan 32 (air 82), forming a circulation path. Therefore, the warm air 84 that absorbs heat from the heat source inside the case 2 is cooled by the airflow 81 generated by the fan 32 by dissipating heat from the outside of the case 2 and the inner wall of the base 1, and the cooled air 82 cools the heat source. This improves the cooling capacity, and the IC board 311 and the optical communication board 312 are cooled.

[0039] Furthermore, by forming the circulation path as a duct shape using the case 2 including the exchange part 3, it is possible to prevent the fan 32 from drawing in the warm air (space 86) near the heat source, and instead to draw in the air 82 cooled by the inner wall of the base 1, thereby improving the cooling capacity.

[0040] 10 is a side cross-sectional view of the inside of the base unit 10 as viewed from the y-axis direction. As shown in FIGS. 5 and 10, the case unit 2 has a duct shape, and the optical communication sheet metal 36 as a sheet metal wall is held by the exchange unit 3 inside the case unit 2, thereby dividing the space inside the case unit 2. The divided circulation paths 88 and 89 divide the space into two: a space 86 on the IC board 311 side as a first path, and a space 87 on the optical communication board 312 side as a second path.

[0041] The cross-sectional area 86a of the space 86 on the IC substrate 311 side relative to the airflow direction (-y direction) in the duct is larger than the cross-sectional area 87a of the space 87 on the optical communication substrate 312 side. The heat generation amount of the IC substrate 311 is larger than that of the optical communication substrate 312. In other words, the size of the cross-sectional area relative to the airflow and the magnitude of the heat generation amount of the heat source are in the same relationship. This corresponds to the characteristic of an axial flow fan, in which high resistance in the duct significantly reduces the flow rate. The effect of reducing resistance and the effect of increasing the flow rate distribution by increasing the cross-sectional area on the side with higher heat generation ensures a sufficient flow rate, thereby increasing the heat transport rate and improving cooling capacity.

[0042] 1, 5, and 7, the IC board 311 and the optical communication board 312 are arranged on a plane parallel to the direction of gravity (z-axis). In addition, the exhaust port 24 in the case 2 is on a plane perpendicular to the plane (x-axis) of the external connector metal plate 34. The air flow at the intake port 371 is perpendicular to the direction of gravity.

[0043] This allows air 83 flowing from exhaust port 24 toward intake port 371 to easily pass through the inner wall of base 1, which is a surface parallel to the direction of gravity. The inner wall of base 1, which is a surface parallel to the direction of gravity, has an improved cooling effect on air 8 inside base 1 because light blocking member 5 is disposed outside the corresponding outer wall and surface 13, which is parallel to the direction of gravity, has a high heat dissipation effect from the outer wall to the outside air.

[0044] Furthermore, even if the temperature of the air passing through space 86 on the IC board 311 side is different from the temperature of the air passing through space 87 on the optical communication board 312 side, the characteristics of air intake port 321 of fan 32, which is an axial flow fan, allow the air from various directions to be mixed together (air 82). This makes it possible to lower the temperature of the air blown onto the heat source in each circulation path.
