Detailed Description

It is easily understood that, according to the technical solution of the present invention, under the spirit of the present invention, a person skilled in the art can propose various alternative structural modes and implementation modes. Therefore, the following detailed description and the accompanying drawings are only exemplary of the technical aspects of the present invention, and should not be considered as limiting or restricting the technical aspects of the present invention in its entirety or as limiting or restricting the technical aspects of the present invention.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 1, a schematic structural diagram of an optical lens according to the present invention is shown.

The optical lens 1 has a lens group 11 and a lens barrel 12, the lens group 11 is at least partially assembled in the lens barrel 12, the lens group 11 includes a first lens 111 and a second lens 112 (5 lenses are exemplarily shown in the figure), the first lens 111, the second lens 112 and the lens barrel 12 form a cavity 13, the optical lens 1 further has a humidity control coating 14 for controlling humidity, and the humidity control coating 14 is partially coated on the cavity 13.

It should be noted that the optical lens may be understood as a head portion of the entire image pickup apparatus, and may also be broadly understood as a camera. The optical lens may be, for example, a vehicle-mounted camera, a surround view camera, a motion camera, a movie camera, an unmanned aerial vehicle camera, or the like. "the lens group 11 is at least partially assembled in the lens barrel 12" means that at least a portion of the lens group 11 is located in the lens barrel 12, and it is not necessary that all of the lens group 11 is located in the lens barrel 12. For example, in the embodiment shown in the figures, the left half of the leftmost lens (i.e., the first lens 111) extends beyond the lens barrel 12, the right half is located inside the lens barrel 12, and the rest of the lenses are all disposed inside the lens barrel 12.

By "the first lens 111, the second lens 112, and the barrel 12 form the cavity 13" is meant that the boundary of the cavity 13 is defined by these parts, and therefore the application of the moisture control coating 14 to the cavity 13 is meant to encompass the application of the moisture control coating 14 to the boundary surface of the parts, and also the application of the moisture control coating 14 to any part disposed within the cavity 13, including the spacer 16, as will be further described below. By "the moisture control coating 14 is partially applied to the cavity 13" is meant that the moisture control coating 14 is applied to a portion of the cavity 13. In the embodiment shown in the figure, the humidity control coating 14 is not coated on the first transparent portion 1112 on the right side of the first lens 111 and is not coated on the second transparent portion 1122 on the left side of the second lens 112, because these transparent portions are used for transmitting light during the image capturing process and are sensitive to light, so this design way avoids the humidity control coating (even if it is transparent) from possibly affecting the optical properties such as light transmittance.

Further, it is understood that the humidity control coating is used to control humidity, i.e., to perform moisture absorption and release functions in the case of excessively high humidity and excessively low humidity, respectively, and has good durability without losing the functions due to multiple uses. The moisture control coating can be natural coating (natural zeolite, natural diatomite, natural attapulgite, montmorillonite, sepiolite, kaolin, gypsum, etc.), inorganic coating (including calcium silicate, artificial zeolite, silica gel, etc.), or organic coating (starch, cellulose or synthetic resin with a three-dimensional network with a low degree of crosslinking as a framework). It should also be understood that the application of the humidity control coating can be performed during the manufacturing stage of the optical lens 1, and the manufacturing of the optical lens with the humidity control function can be completed in one step without performing the application of the humidity control coating after the optical lens is manufactured.

In the past, the water vapor in the camera is controlled by some heating or large-volume water absorption devices. And through the above technical scheme of the utility model, can control the inside steam of optical lens to the occupation of land space of the wet coating of accuse is few, the space requires lowly, does not need to change the structure of camera in addition, has realized the antifog effect of camera with an extremely simple and convenient mode.

It can also be seen from the figure that the optical lens 1 further has a pressure ring 18, the pressure ring 18 having a vertical extension on the left for snapping the first lens 111, and furthermore the pressure ring 18 having a horizontal extension on the right for connecting, for example screwing, with the lens barrel 12. The press ring 18 is located at the outermost radial side of the whole optical lens 1, and plays a role in protecting, assembling and stabilizing various parts in the press ring. In addition, all the components of the optical lens 1 except the press ring 18 are formed by stacking, so that the whole optical lens 1 is very compact, requires a small floor space, and has a stable structure. By stacked, it is meant that for each part there is always at least one adjacent part in direct contact therewith.

Furthermore, the first lens 111 can be the lens that is at the forefront when the optical lens 1 is used (the leftmost lens in the figure, that is, the side that is in contact with the external environment), and the second lens 112 is adjacent to the first lens 111 (the second lens from the left in the figure). In this design, it is considered that in actual use, lens fog of the optical lens 1 is mostly concentrated on the inner surface of the outermost lens, so that the humidity control coating 14 can be applied to the cavity between the outermost lens and the adjacent lens, so as to perform targeted humidity control for practical application, and meanwhile, the cost of humidity control can be kept low, and the cost performance is high.

Referring to fig. 2-5, various examples of applying humidity control coatings within optical lenses according to the present invention are shown, respectively.

The optical lens 1 further has a waterproof ring 15, the waterproof ring 15 abuts between the supporting surface 1111 of the first lens 111 and the abutting surface 121 of the lens barrel 12, and the humidity control coating 14 is coated on the supporting surface 1111, which can be seen schematically in fig. 2, for example. The support surface 1111 in the embodiment shown in the figures is the entire vertical surface of the rightmost side of the first lens 111, and is used to provide a support surface for the components adjacent thereto, such as the waterproof ring 15 and the spacer ring 16 mentioned below. The abutment surface 121 is also a vertical surface of the lens barrel 12 and provides a supporting function. In this embodiment, since the supporting surface 1111 is the integral transition area from the ambient air to the lens cavity, the moisture control coating 14 applied thereto can control the humidity in a targeted manner and achieve a significant control effect.

The designs of fig. 3 to 5 can achieve similar technical effects, and are not described herein again. For example, the optical lens 1 also has a spacer 16, the spacer 16 is arranged between the support surface 1111 of the first lens 111 and the second lens 112, and the humidity control coating 14 is applied on the inner surface and the outer surface of the spacer 16. It should be understood that a corresponding spacer ring may be disposed between each lens of the lens group 11 to provide a corresponding fixing and separating function for each lens, and the shape of each lens and each spacer ring need not be completely consistent, but may be changed according to actual needs. For this purpose, a respective support surface (e.g. the support surface 1111 of the first lens 111 and the abutment surface 1121 of the second lens 112, which will be mentioned later) can be provided on the surface of each lens for the assembly of a respective spacer. Furthermore, the number of optical lenses and spacers can be variable, for example, n +1 optical lenses and n spacers can be included.

As another example, the humidity control coating 14 is coated on the lens barrel 12 from the abutting surface 121 until the lens barrel 12 contacts the second lens 112, as can be seen in fig. 4, for example. That is, the humidity control coating 14 is applied to the abutting surface 121 of the lens barrel 12, and is continuously applied to the horizontal transition surface of the lens barrel 12 in the horizontal rightward direction, and is finally applied obliquely rightward and downward to the contact position. The contact point is an end point on the left side of the contact line between the second lens 112 and the lens barrel 12 when viewed from the plan view (the left side is the front side when the optical lens 1 is used as an example). This allows the transition region of the air from the outside to the inside to be coated to a greater extent and the humidity control effect resulting therefrom.

As already mentioned above, it can be seen from fig. 4 that the second lens 112 supports the spacer ring 16 by its abutting surface 1121, and the humidity control coating 14 is applied to the abutting surface 1121. It should be understood that the specific shape of the abutment surface 1121 may be matched with the shape of the corresponding spacer ring to achieve a better supporting effect.

In addition, the optical lens 1 has a color filter 17, the color filter 17 is provided in the lens barrel 12 and is disposed at an end portion at the rear side when the optical lens 1 is used, and the humidity controlling paint 14 is coated on the color filter 17. It should be understood that the color filter 17 can be a tinted transparency having absorbing, reflecting and transmitting effects on color light, which may also be referred to as a color filter or a color filter. In this example, the color filter 17 is formed in a plate shape and is fitted in a groove provided for this purpose in the lens barrel 12. This design is used to provide a comprehensive humidity control effect.

It should also be understood that the various applications described above with respect to the moisture control coating 14 are not exclusive and may be combined with each other and employed simultaneously. The determination can be specifically carried out according to actual needs and cost budget.

Further, the thickness of the moisture control coating 14 may be 0.003 mm to 0.1 mm. Therefore, the thickness of the humidity control coating is very thin, the structure of the existing parts of the optical lens 1, the connection relation and the position relation among the parts are not substantially influenced, the coating time and the money cost are low, the whole production process of the optical lens is not substantially influenced, and the ideal humidity control effect can still be realized.

It should be understood that the optical lens 1 of the present invention can be installed on various vehicles, including gasoline vehicles, diesel vehicles, cars, trucks, buses, hybrid vehicles, pure electric vehicles, etc. Therefore, the subject matter of the present invention is also intended to protect various vehicles equipped with the optical lens 1 of the present invention. For example, the vehicle may be an unmanned vehicle. This is because the safety issues of unmanned technology are of paramount importance, which in turn relies on cameras as the primary vision solution. Therefore, it is critical for the unmanned industry to solve the fogging problem of the on-vehicle optical camera.

To sum up, through the technical scheme of the utility model for humidity, the steam content of the cavity inside between the optical lens piece can keep at a lower state, have restrained the inside fog of camera and have produced, have greatly improved the inside phenomenon of hazing of optical lens.

It should be understood that all the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above may be made by those skilled in the art without departing from the spirit of the invention.
