Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.
As shown in fig. 1, 2 and 5, an embodiment of a first aspect of the present application proposes a camera housing. The camera housing includes a front case 100 and a rear case 200. Specifically, the front case 100 is a first double-layered heat dissipation structure, the front case 100 is configured to dissipate heat of the first heat generating element 300 of the camera, and the first double-layered heat dissipation structure includes a first conductive thermoplastic shell 110 at an inner layer and a first engineering plastic shell 120 at an outer layer. The rear housing 200 is connected to the front housing 100, the rear housing 200 is a second double-layer heat dissipation structure, the rear housing 200 is configured to dissipate heat of the second heating element 400 of the camera, and the second double-layer heat dissipation structure includes a second conductive thermoplastic shell 210 located at an inner layer and a second engineering plastic shell 220 located at an outer layer.
It can be understood that the camera housing in the embodiment of the present application is particularly suitable for camera products with waterproof sealing requirements, such as high-power surveillance cameras. For such camera products, no heat dissipation holes are formed in the camera housing, and therefore the camera housing needs to be designed to dissipate heat.
According to the camera housing of the embodiment of the present application, the front housing 100 adopts a first double-layer heat dissipation structure, the rear housing 200 adopts a second double-layer heat dissipation structure, and the first double-layer heat dissipation structure and the second double-layer heat dissipation structure each include a heat-conducting plastic shell located at an inner layer and an engineering plastic shell located at an outer layer. Since the thermal conductivity of the conductive thermoplastic shell is significantly greater than that of the engineering plastic shell, the heat generated by the first and second heat generating elements 300 and 400 of the camera during operation is first transferred to the first and second conductive thermoplastic shells 110 and 210 of the inner layer, and is laterally diffused and rapidly transferred in the inner layer, so that the temperature of the entire first and second conductive thermoplastic shells 110 and 210 is increased. Then, the heat is transferred through the contact surface between the first conductive thermoplastic shell 110 and the first engineering plastic shell 120 and the contact surface between the second conductive thermoplastic shell 210 and the second engineering plastic shell 220, so that the temperature of the first engineering plastic shell 120 and the second engineering plastic shell 220 at the outer layers is increased. Finally, the first engineering plastic shell 120 and the second engineering plastic shell 220 on the outer layers exchange heat with the external air environment, so that heat dissipation is realized. The camera shell of this application embodiment, compare in metal casing, have weight and lower cost relatively lighter to difficult scald risk that leads to also can not conduct static.
It should be noted that the heat conductive plastic is an existing material. Specifically, the heat conductive plastic is a plastic composite material compounded by adding a heat conductive metal oxide, graphite fiber or carbon fiber and the like into common plastic, and the heat conductivity coefficient of the heat conductive plastic can reach 0.5-10W/(M.k).
In some embodiments of the present application, the first dual-layer heat dissipation structure and the second dual-layer heat dissipation structure may be an integrated structure formed by a secondary injection molding process, and a contact fit gap between two layers of plastic materials may be better improved by the secondary injection molding process, so as to reduce a thermal contact resistance between the two layers of materials. Further, since the contact surface of the heat-conducting plastic and other engineering plastics after injection molding has no adhesiveness, a structural reverse buckle 700 (refer to fig. 4) can be designed between the two layers of materials to pull the two layers of materials together, thereby preventing the two layers of materials from separating and falling off during demolding.
In some embodiments of the present application, a sealing ring is provided between the front housing 100 and the rear housing 200. Generally, the heat generation amounts of the first and second heat generation elements 300 and 400 are different. Therefore, a temperature difference may be formed between the front case 100 and the rear case 200. Taking the case where the heat generation amount of the first heat generation element 300 is larger than that of the second heat generation element 400 as an example, the temperature resistance of the first heat generation element 300 is also better than that of the second heat generation element accordingly. Based on the fact that there is a temperature difference between the front housing 100 and the rear housing 200, the front housing 100 and the rear housing 200 are separated by the sealing ring, so that heat conduction between the front housing 100 and the rear housing 200 can be avoided, thereby maintaining the temperature difference therebetween, so as to form a design result that the temperature of the front housing 100 is higher than that of the rear housing 200, and the temperature of the first heating element 300 is higher than that of the second heating element 400, thereby enabling the temperatures of the first heating element 300 and the second heating element 400 to reach the standard, and the temperature margin is not too large.
In some embodiments of the present application, as shown in fig. 2 and 3, a positioning frame 111 for mounting the first heat generating element 300 and capable of being attached to the first heat generating element 300 is formed on the first conductive thermoplastic shell 110. It is understood that the positioning frame 111 is integrally formed with the first conductive plastic shell 110, i.e. the positioning frame 111 is also made of a heat conductive plastic material. Therefore, the first heating element 300 is attached to the positioning frame 111 in a fitting manner, so that heat generated by the first heating element 300 during operation can be directly transferred to the first conductive thermoplastic shell 110.
Further, the camera housing further includes a front cover 600, the front cover 600 is hermetically connected to the front side of the front housing 100, and the front cover 600 may be a transparent glass cover, so that external light can be received by a lens module disposed in the camera housing. A spacer 111 is formed at the front end of the first conductive thermoplastic shell 110. The positioning frame 111 in this embodiment is formed at the front end of the first conductive thermoplastic shell 110, so that the first heat generating element 300 can be more conveniently mounted without assembling the front cover 600 and the front housing 100.
Specifically, glue may be dispensed at a connection portion of the front cover 600 and the front housing 100, that is, the front cover 600 and the front housing 100 are connected by using a sealant, so as to achieve sealing therebetween.
Embodiments of the second aspect of the present application propose a camera comprising a first heat generating element 300, a second heat generating element 400 and a camera housing of any of the embodiments described above.
According to the camera of the embodiment of the application, the front shell 100 of the camera shell adopts a first double-layer heat dissipation structure, the rear shell 200 adopts a second double-layer heat dissipation structure, and the first double-layer heat dissipation structure and the second double-layer heat dissipation structure both comprise a heat-conducting plastic shell positioned at an inner layer and an engineering plastic shell positioned at an outer layer. Since the thermal conductivity of the conductive thermoplastic shell is significantly greater than that of the engineering plastic shell, the heat generated by the first and second heat generating elements 300 and 400 of the camera during operation is first transferred to the first and second conductive thermoplastic shells 110 and 210 of the inner layer, and is laterally diffused and rapidly transferred in the inner layer, so that the temperature of the entire first and second conductive thermoplastic shells 110 and 210 is increased. Then, the heat is transferred through the contact surface between the first conductive thermoplastic shell 110 and the first engineering plastic shell 120 and the contact surface between the second conductive thermoplastic shell 210 and the second engineering plastic shell 220, so that the temperature of the first engineering plastic shell 120 and the second engineering plastic shell 220 at the outer layers is increased. Finally, the first engineering plastic shell 120 and the second engineering plastic shell 220 on the outer layers exchange heat with the external air environment, so that heat dissipation is realized. The camera shell that the camera of this application embodiment adopted compares in metal casing, has weight and lower cost relatively lighter to difficult scald risk that leads to can not conduct static yet.
In some embodiments of the present application, as shown in fig. 1, the camera housing further includes a heat conductive sheet metal part 500 disposed in the rear housing 200, the heat conductive sheet metal part 500 is connected to the second heat conductive plastic shell 210, the second heat generating element 400 is mounted to the heat conductive sheet metal part 500, and the first heat generating element 300 is mounted to the first heat conductive plastic shell 110. The heat generation amounts of the first heat generation element 300 and the second heat generation element 400 are generally different from each other, and the case where the heat generation amount of the first heat generation element 300 is larger than the heat generation amount of the second heat generation element 400 is exemplified (the temperature resistance of the first heat generation element 300 is also better than that of the second heat generation element 400). At this time, the first heating element 300 is directly installed in the first conductive thermoplastic shell 110, heat generated by the first heating element 300 is directly transferred to the first conductive thermoplastic shell 110, the second heating element 400 is installed in the heat conductive sheet metal member 500, and heat generated by the second heating element 400 is transferred to the second conductive thermoplastic shell 210 through the heat conductive sheet metal member 500. This results in a design result in which the temperature of the front case 100 is higher than that of the rear case 200 and the temperature of the first heat generating element 300 is higher than that of the second heat generating element 400, so that the temperatures of the first heat generating element 300 and the second heat generating element 400 can reach the standards without an excessive temperature margin.
In some embodiments of the present application, a plurality of first contact surfaces (not shown) are formed on the inner side of the second thermally conductive plastic shell 210, and a plurality of second contact surfaces 501 are formed on the thermally conductive sheet metal member 500, wherein each second contact surface 501 is in contact with a corresponding first contact surface through a thermally conductive interface material (e.g., a thermally conductive pad, a thermally conductive silicone grease, etc.). In this embodiment, a plurality of first contact surfaces and second contact surfaces 501 attached to each other are correspondingly disposed on the inner side of the second heat conductive plastic shell 210 and the heat conductive sheet metal part 500, and the first contact surfaces and the second contact surfaces 501 are in contact with each other through a heat conductive interface material, so that the heat of the heat conductive sheet metal part 500 can be sufficiently and uniformly transferred to the rear housing 200, and the rear housing 200 is uniformly heated, that is, the average temperature of each part of the rear housing 200 is increased, and accordingly, the heat dissipation effect of the whole camera is also improved.
In some embodiments of the present application, as shown in fig. 5 to 7, a plurality of screw columns 221 are formed inside the second engineering plastic shell 220, and the heat-conducting sheet metal part 500 is fixedly connected with the screw columns 221 by screws. Since the heat conductive plastic material is brittle, the tapping screw is easily broken, and the generated chips may cause short circuit of the circuit board. Therefore, the screw column 221 is designed on the second engineering plastic shell 220, and the heat-conducting sheet metal part 500 is connected with the screw column 221 through a screw, that is, the assembly between the heat-conducting sheet metal part 500 and the rear shell 200 is realized. In addition, besides the screw column 221, other force-bearing structures may be designed and arranged on the first or second engineering plastic shell 220.
Further, the first heat generating element 300 may be, for example, a lamp panel assembly.
Further, the second heat generating element 400 may be, for example, a main board assembly.
