Description

Technical Field

[0001] The present application relates to the technical field of image acquisition equipment, and in particular to a housing for a camera and a camera. Background Art

[0002] Cameras are increasingly used in industrial measurement and inspection. During the operation of the camera, the mainboard and some image acquisition components will generate heat (for example, the image acquisition components in a laser 3D camera generally include a laser module and a lens module. The laser in the laser module and the sensor circuit board in the lens module will generate heat during operation). Large temperature rise will seriously affect the performance of optical devices, resulting in reduced linearity, repeatability and stability of the measurement. Especially for optical devices such as lasers that are sensitive to temperature rise, the "temperature drift" problem will be more serious when encountering large temperature rises.

[0003] In order to solve the above problems, three solutions are generally adopted in the related technology: one solution is to reduce the power of the mainboard and directly reduce the heat generated by the whole machine, but this will inevitably reduce the working performance of the camera; another solution is to set heat dissipation fins on the outer casing of the camera to dissipate heat through heat convection with the outside world, but this solution is not effective for high-power motherboards, and there is still a problem of reduced camera performance in actual applications; another solution is to set a refrigeration device inside the camera, but this solution is relatively expensive and may affect the life of electronic components due to condensation problems.

DETAILED DESCRIPTION

[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0034] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] After research, the inventor found that the main heat-generating component in the camera is the mainboard, and the component in the camera that is more sensitive to temperature rise is the image acquisition component. The heat transfer efficiency of the mainboard to the image acquisition component through the camera housing is much higher than the heat transfer efficiency of the camera housing to the outside through thermal convection, and the heat generated by the mainboard will also be transferred to the image acquisition component through thermal convection inside the camera housing. This leads to the problem of rapid temperature rise in the image acquisition component, which in turn affects the working performance of the camera.

[0036] This embodiment provides a housing for a camera, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in , the housing includes a first shell 1, a second shell 2, a heat insulating ring 3 and a heat insulating plate 4 fixedly installed in one body. The heat insulating ring 3 is arranged between the first shell 1 and the second shell 2 to separate the two, and the heat insulating ring 3 cooperates with the first shell 1 and the second shell 2 to form an installation space. The heat insulating plate 4 is arranged in the installation space and divides the installation space into a first cavity 5 and a second cavity 6. The first cavity 5 is used to install the image acquisition component of the camera, and the second cavity 6 is used to install the main board 9 of the camera. The heat insulating plate 4 is also provided with a wiring hole 40 that connects the first cavity 5 with the second cavity 6.

[0037] The solutions in the related art either consider reducing the heat generation or improving the heat dissipation (cooling) capacity when solving the above-mentioned problems. However, the present application, without changing the existing natural heat dissipation through the outer shell and the outside world, sets a heat insulation ring 3 and a heat insulation plate 4. On the one hand, the heat insulation ring 3 is used to separate the first shell 1 from the second shell 2, thereby reducing the heat conduction efficiency between the first shell 1 and the second shell 2; on the other hand, the heat insulation plate 4 is used to separate the installation space inside the outer shell into the first cavity 5 and the second cavity 6, thereby reducing the heat convection efficiency between the first cavity 5 and the second cavity 6. In this way, the heat generated by the mainboard 9 can be significantly reduced from being transferred to the image acquisition component, thereby reducing the temperature rise of the image acquisition component and reducing the impact on the working performance of the camera.

[0038] This embodiment also shows a camera using the housing provided by the present application, which includes an image acquisition component and a mainboard 9, wherein the image acquisition component is arranged in the first cavity 5, the mainboard 9 is arranged in the second cavity 6, and the image acquisition component and the mainboard 9 are electrically connected by a cable passing through the wiring hole 40. Specifically in this embodiment, the image acquisition component includes a laser module 7 and a lens module 8, and a light exit hole 13 corresponding to the laser module 7 and a light-collecting hole 14 corresponding to the lens module 8 are also arranged on the first housing. During the operation of the camera, the mainboard 9 and the image acquisition component located in the housing will generate heat, and the heat emitted by the mainboard 9 can be thermally conducted to the first housing 1, and then dissipated by thermal convection with the outside through the first housing 1. The heat emitted by the image acquisition component can be thermally conducted to the second housing 2, and then dissipated by thermal convection with the outside through the second housing 2. Due to the effects of the heat insulation ring 3 and the heat insulation board 4, only a very small part of the heat emitted by the mainboard 9 can be transferred to the image acquisition component along the first housing 1, the heat insulation ring 3, and the second housing 2 by heat conduction. This can reduce the heat generated by the mainboard 9 from being transferred to the image acquisition component, thereby reducing the temperature rise of the image acquisition component and reducing the impact on the camera's working performance. Fig.10 As shown in the figure, in this embodiment, a thermal pad 15 is further provided between the mainboard 9 and the inner wall of the first shell 1, so that the heat generated by the mainboard 9 can be quickly transferred to the first shell 1 by heat conduction, thereby accelerating the heat transfer to the outside.

[0039] In order to improve the heat dissipation efficiency of the first shell 1 and the second shell 2 in heat convection with the outside world, the first shell 1 and the second shell 2 in this embodiment are both made of metal material, specifically, both are made of aluminum alloy. Of course, aluminum material, stainless steel material, tempered glass material, ceramic material, plastic material, etc. can also be used. A heat dissipation fin structure can also be set on the outside of the first shell and the second shell. The insulation ring 3 and the insulation board 4 are both made of plastic material, especially polystyrene board, polyurethane foam board, extruded polystyrene foam board and other plastic materials with good heat insulation ability. In some other optional implementations, insulation materials such as glass fiber, asbestos, vacuum board, aerogel pad, etc. can also be selected.

[0040] like Figure 2As shown in, as mentioned above, in order to realize the electrical connection between the image acquisition component located in the first chamber and the main board 9 located in the second chamber, a wiring hole 40 is also provided on the heat insulation board 4 in this embodiment, so that a cable can be passed through the wiring port, and the image acquisition component is electrically connected to the main board 9 through the cable, so as to realize the signal control and data transmission between the main board 9 and the image acquisition component. Since it is necessary to electrically connect the main board 9 to the laser module 7 and the lens module 8 respectively, two rectangular wiring holes 40 are provided in this embodiment. In order to prevent the heat generated by the main board 9 from being transferred to the second chamber through the wiring holes 40 by heat convection, the housing provided in this embodiment also includes an elastic heat insulating member 41 provided at the wiring hole 40, and the elastic heat insulating member 41 is used to close the wiring hole 40. Specifically, the elastic heat insulating member 41 in this embodiment is a heat insulating foam. In other optional embodiments, glass wool, aerogel pads, etc. can also be selected as elastic heat insulating members.

[0041] like Figure 2 As shown in , in this embodiment, a first sealing ring 12 is sandwiched between the insulation ring 3 and the first shell 1, and a second sealing ring 23 is sandwiched between the insulation ring 3 and the second shell 2. Specifically, the first shell 1 in this embodiment includes a first bottom wall 10 and a first side wall 11 arranged around the first bottom wall 10, and the second shell 2 includes a second bottom wall 20 and a second side wall 21 arranged around the second bottom wall 20. Sealing grooves are respectively arranged on the end surface of the first side wall 11 and the end surface of the second side wall 21, and the first sealing ring 12 and the second sealing ring 23 are respectively arranged in the corresponding sealing grooves, and then the first sealing ring 12 and the second sealing ring 23 are clamped by the fixed connection between the first shell 1 and the second shell 2. By providing the first sealing ring 12 and the second sealing ring 23, the camera can have good dustproof and waterproof effects. In addition, the first sealing ring 12 and the second sealing ring 23 are both made of rubber material, and the thermal conductivity of the rubber material is low, which can cooperate with the insulation ring 3 to play a good insulation effect between the first shell 1 and the second shell 2.

[0042] Furthermore, in addition to solving the problem that the temperature rise affects the working performance of the camera, the housing provided in this embodiment also designs the overall structure of the housing from the perspective of easy assembly. Figure 2 and Figure 4As shown in , in this embodiment, the first bottom wall 10 and the first side wall 11 in the first shell 1 cooperate to form a concave cavity with an opening, the heat insulation board 4 is located in the concave cavity and is arranged close to the opening, and the heat insulation board 4 cooperates with the first bottom wall 10 and the first side wall 11 to form a first cavity 5. That is, taking the placement method in which the first shell 1 is located at the bottom and the second shell 2 is located at the top as an example, the heat insulation board 4 in this embodiment is located below the heat insulation ring 3. In this way, the portion of the first side wall 11 that is higher than the heat insulation board 4 cooperates with the heat insulation board 4, the heat insulation ring 3 and the second shell 2 to form the aforementioned second cavity 6. Combined with Figure 5 As shown in the figure, the above-mentioned design scheme is adopted, which makes it convenient to set a connection structure for connecting with the insulation board 4, the main board 9, the insulation ring 3, the first shell 1, etc. on the first shell 1, and makes it convenient to assemble the insulation board 4, the main board 9, the insulation ring 3, the first shell 1, etc. one by one on the first shell 1 from bottom to top.

[0043] Combination Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in , in order to realize the assembly of the heat insulation board 4, in this embodiment, a first mounting protrusion 110 is formed on the first side wall 11, and the first mounting protrusion 110 has a first assembly surface. The heat insulation board 4 is arranged in contact with the first assembly surface and is fixedly connected to the first mounting protrusion 110. Specifically in this embodiment, a threaded hole is provided on the first mounting protrusion 110, and a through hole is provided on the heat insulation board 4. A screw is passed through the through hole on the heat insulation board 4 and then screwed into the threaded hole on the first mounting protrusion 110, so that the heat insulation board 4 can be fixedly installed on the first mounting protrusion 110. In order to facilitate the distinction between the screws used at different installation positions, in this embodiment, the screw used to install the heat insulation board 4 is referred to as the first screw 42, that is, the heat insulation board 4 is locked and fixed to the first mounting protrusion 110 using the first screw 42.

[0044] In order to realize the assembly of the mainboard 9, in this embodiment, a second mounting protrusion 111 is formed on the first side wall 11, and the housing further comprises a support column 112 detachably mounted on the second mounting protrusion 111, the end surface of the support column 112 forms a second assembly surface for mounting the mainboard 9, and the support column 112 is provided with a threaded hole for cooperating with a screw, so that the mainboard 9 is mounted on the support column 112 by means of a screw (not shown in the figure) passing through the mainboard 9. In order to facilitate the assembly operation, in this embodiment, the support column 112 and the second mounting protrusion 111 are designed separately, and after the assembly of the heat insulation board 4 is completed, the support column 112 is fixedly mounted on the second mounting protrusion 111, and then the mainboard 9 is assembled. Specifically, the threaded hole is provided at one end of the support column 112, and a flange for connecting to the second mounting protrusion 111 is formed at the other end of the support column 112, and a through hole is provided on the flange. The support column 112 can be fixedly installed on the second mounting protrusion 111 by using the second screw 1120 to pass through the through hole on the flange and tighten it into the threaded hole on the second mounting protrusion 111.

[0045] The first assembly surface, the second assembly surface, and the third assembly surface 100 and the fourth assembly surface 101 described here all refer to high-precision assembly surfaces with high flatness. By setting high-precision assembly surfaces, assembly reliability and assembly accuracy can be guaranteed. Among them, the third assembly surface 100 and the fourth assembly surface 101 are arranged at the bottom of the first bottom wall 10, and a groove structure or a protrusion structure is arranged on the first bottom wall 10, and the third assembly surface 100 and the fourth assembly surface 101 are formed on the bottom wall of the groove structure or the end face of the protrusion structure. The third assembly surface 100 is used to install the laser module 7, and the fourth assembly surface 101 is used to assemble the lens module 8.

[0046] Furthermore, in order to meet the conductive requirements of electromagnetic compatibility (EMC), in this embodiment, the support column 112 is configured to be electrically connected to the first housing 1. Specifically, in this embodiment, the first housing 1 and the support column 112 are both made of conductive metal materials. In this way, the mainboard 9 placed on the support column 112 can achieve EMC conduction with the laser module 7 and the lens module 8 through the support column 112 and the first housing 1, meet the overall electromagnetic compatibility requirements of the camera, and improve the camera's anti-electromagnetic interference capability.

[0047] Since the contact area between the support column 112 and the mainboard 9 is small, and the contact position between the support column 112 and the mainboard 9 can be designed to be in an area on the mainboard 9 where less heat is generated, the heat transferred from the support column 112 to the first shell 1 is within an acceptable range. Of course, in some optional embodiments, it is also possible to choose to use a material with heat insulation properties to make the support column, such as using plastic to make the support column. Then, a through threaded hole is opened on the support column, and a conductive film is coated in the threaded hole, so that the mainboard can achieve electrical conduction with the support column through a screw that passes through the mainboard and is tightened in the threaded hole on the support column, and at the same time, the heat transferred from the support column to the first shell can be reduced.

[0048] Combination Figure 2 , Figure 3 , Figure 5 , Figure 8 and Fig. 9 As shown in , in order to realize the assembly of the heat insulation ring 3, in this embodiment, a connecting column 113 is formed on the end surface of the first side wall 11, a threaded hole is provided on the connecting column 113, and the heat insulation ring 3 is provided with a first connecting hole 30 adapted to the connecting column 113, and the connecting column 113 penetrates the first connecting hole 30. A second connecting hole 22 coaxial with the first connecting hole 30 is provided in the second shell 2, and the second shell 2 and the heat insulation ring 3 are fixedly installed on the first shell 1 by a third screw 24 penetrating the second connecting hole 22 and tightened in the threaded hole.

[0049] Furthermore, when placing the heat insulating ring 3, the connecting column 113 can be used to cooperate with the first connecting hole 30 to achieve preliminary positioning of the heat insulating ring 3, but when placing the second shell 2, it is difficult to rely on the connecting column 113 to achieve positioning. Therefore, in this embodiment, the end surface of the first side wall 11 is also formed with a positioning column 114, the length of the positioning column 114 is greater than the length of the connecting column 113, the heat insulating ring 3 is provided with a positioning hole 31 adapted to the positioning column 114, and the second shell 2 is provided with a positioning groove adapted to the positioning column 114, and the positioning column 114 passes through the positioning hole 31 and extends into the positioning groove. After such a setting, the second shell 2 can achieve preliminary positioning through the positioning column 114 passing through the positioning hole 31, which is convenient for assembly operation.

[0050] The assembly process of the camera using the housing provided in this embodiment is described as follows: First, the laser module 7 and the lens module 8 are respectively mounted on the third assembly surface 100 and the fourth assembly surface 101 on the first bottom wall 10. Secondly, the heat insulation board 4 is placed on the first assembly surface and mounted on the first mounting protrusion 110 by the first screw 42. While assembling the heat insulation board 4, the FPC cables on the laser module 7 and the lens module 8 are respectively passed through the wiring holes 40 provided on the heat insulation board 4, and the wiring holes 40 are blocked with heat insulation foam after threading. After that, the first sealing ring 12 and the support column 112 are assembled, the first sealing ring 12 is placed in the sealing groove on the first side wall 11, and the support column 112 is locked and fixed on the second mounting protrusion 111 by the second screw 1120. Then, the main board 9 is placed on the second assembly surface on the support column 112, and the main board 9 is locked and fixed on the support column 112 by screws. Then assemble the heat-insulating ring 3, align the first through-hole on the heat-insulating ring 3 with the connecting column 113 on the first side wall 11, and align the positioning hole 31 on the heat-insulating ring 3 with the positioning column 114 on the first side wall 11, and place the heat-insulating ring 3 on the end face of the first side wall 11. Then place the second sealing ring 12 in the sealing groove on the second side wall 21, and align the positioning groove on the second housing 2 with the positioning column 114 that passes through the positioning hole 31, and place the second housing 2 on the heat-insulating ring 3. Finally, use five third screws 24 to penetrate into the second through-holes and tighten them into the threaded holes on the connecting column 113 to complete the assembly of the camera.

[0051] As mentioned above, in this embodiment, the second shell 2 includes a second bottom wall 20 and a second side wall 21 arranged around the second bottom wall 20, and the heat-insulating ring 3 is sandwiched between the end face of the first side wall 11 and the end face of the second side wall 21. In an optional embodiment, the second shell can also be designed as a flat plate structure, and accordingly, the heat-insulating ring is sandwiched between the end face of the first side wall and the flat plate. In this solution, the thickness of the heat-insulating ring needs to be increased so that a second cavity with a size sufficient to meet the requirements can be constructed.

[0052] In addition, if Figure 4 As shown in the figure, in this embodiment, the heat insulation board 4 is arranged below the heat insulation ring 3, and the heat insulation ring 3 is installed on the first side wall 11 of the first shell 1. In an optional embodiment, the heat insulation board can also be arranged above the heat insulation ring, or the heat insulation board can also be arranged within the inner ring of the heat insulation ring. It is also possible to set a mounting structure for assembling the heat insulation board and the main board on the heat insulation ring or the second shell, and adjust the overall size of the shell accordingly.
