The utility model provides a camera lens protective assembly 100, this camera lens protective assembly can set up in shooting equipment (not shown) to the protection camera lens receives collision, fish tail in the use, and solves the difference in temperature of lens and shooting equipment, and the camera lens protective assembly that leads to produces the problem of fog.
Referring to fig. 1 to 3, the lens protection assembly 100 includes a first lens 10, a second lens 20 and a connecting member 40. The second lens 20 is located on one side of the first lens 10, the second lens 20 and the first lens 10 are arranged at intervals, the first lens 10 and the second lens 20 arranged at intervals can avoid direct contact heat transfer of the first lens 10 and the second lens 20, the first lens 10 and the second lens 20 are matched by a connecting piece to form a sealed cavity 30, and the heat conduction efficiency of the sealed cavity is lower than that of the first lens 10 and the second lens 20, so that the heat transfer efficiency between the first lens 10 and the second lens 20 is reduced, and the problem of fogging caused by temperature difference between the lens protection assembly 100 and shooting equipment due to external environment and temperature difference inside the shooting equipment is solved. Compared with the conventional single-layer lens protection assembly, the lens protection assembly 100 of the present invention can reduce the heat transfer efficiency between the first lens 10 and the second lens 20, and can prevent the first lens 10 and the second lens 20 of the lens protection assembly 100 from fogging on the surface. Wherein the sealed cavity 30 having a lower thermal conduction efficiency than the first lens 10 and the second lens 20 may refer to: the overall cavity formed by the first lens 10, the second lens 20 and the connecting member 40, and the filling medium (such as air or other insulating gas if any, or vacuum state if not) in the cavity have a thermal conductivity coefficient lower than that of the material of the first lens 10 and the second lens 20.
For example, referring to fig. 3, taking the second lens 20 disposed at a side close to the lens module 300 as an example, since the thermal conductivity coefficient of the sealed cavity 30 is low, the temperature of the second lens 20 close to the lens does not change greatly with the change of the external environment temperature, but changes with the temperature inside the shooting device, so that the temperature approaches the temperature of the shooting device, and the fog generated by the hot air of the shooting device at the side of the second lens 20 facing the lens can be avoided. Similarly, the temperature of the first lens 10 far away from the lens module 300 is close to the external ambient temperature, so as to prevent the cold air in the environment from generating fog on the side of the first lens 10 far away from the lens. Among them, the temperature inside the photographing apparatus is higher than the temperature of the external environment due to heat generated by the operation of the electronic devices inside the photographing apparatus, such as the CMOS sensor, and therefore, the gas (e.g., air) inside the photographing apparatus is regarded as hot gas and the gas (e.g., air) in the external environment is regarded as cold gas.
Referring to fig. 3, in some embodiments, the connecting member 40 is disposed between the first lens 10 and the second lens 20, and the connecting member 40 is disposed along the contour of the first lens 10 or the second lens 20 to form the sealed cavity 30 in cooperation with the first lens 10 and the second lens 20, that is, the connecting member 40 is disposed between the first lens 10 and the second lens 20 and near the edge of the first lens 10 or the second lens 20, and forms a hollow ring shape to form a hollow cylinder in cooperation with the first lens 10 and the second lens 20, and the main body internal space is the sealed cavity 30.
In this embodiment, the connecting member 40 is disposed near the edge of the first lens 10 or the second lens 20 to increase the volume of the sealing cavity 30, so as to improve the thermal insulation effect between the first lens 10 and the second lens 20, and prevent the hot air in the shooting device from contacting the lens (which has a relatively low temperature) far away from the lens to generate fog.
In addition, compared to the case where the first lens 10 and the second lens 20 are separately mounted on the housing, the housing forms a mounting cavity (refer to the explanation of the second subject "shooting device" about the inner wall of the mounting groove below), the present embodiment forms the sealing cavity by the connection member 40 cooperating with the first lens 10 or the second lens 20, so that the first lens 10, the second lens 20, and the connection member 40 can be produced as a single independent component and directly replace the conventional single-layer lens protection component.
Referring to fig. 3, in some embodiments, the sealed cavity 30 is filled with a thermally insulating gas. Such as one or a combination of carbon dioxide, methane, argon, krypton. The heat-insulating gas has a lower heat conductivity coefficient than ordinary gas, and the heat-insulating effect can be improved.
Referring to fig. 3, in some embodiments, the sealed cavity is filled with air. The air is ambient air, and thus, during the production of the lens protective assembly 100, no special filling is required, so that the difficulty of production can be reduced.
