Description

Technical Field

[0001] The present invention relates to the field of photographic equipment, in particular to an imageable lens cover and an optical lens assembly comprising the imageable lens cover. Background Art

[0002] The optical lens is an important component of the camera, and the lens in the optical lens is an important component of the optical lens. In order to protect the lens, a lens cap is usually provided on the optical lens.

[0003] When users purchase optical lenses, they need to install the optical lenses on their cameras before they can try them out, which is inconvenient as users must carry their cameras with them before they can purchase the optical lenses.

[0004] The traditional lens cover only plays the role of protecting the optical lens and cannot solve the above problems. Summary of the Invention

[0005] Based on this, it is necessary to provide an imageable lens cover that can solve the above problems.

[0006] In addition, it is necessary to provide an optical lens assembly including the above-mentioned imageable lens cover.

[0007] An imaging lens cover comprises a cylindrical side wall and a top cover, wherein the cylindrical side wall and the top cover enclose a cavity, the cavity having a light entrance opening opposite to the top cover, a reflector disposed in the cavity, and a window opening formed in the cylindrical side wall;

[0008] The reflector forms an angle with the axis of the cylindrical side wall, and the reflector reflects the light incident from the light entrance opening and then emits the light from the window opening.

[0009] An optical lens assembly comprises an optical lens and the above-mentioned imageable lens cover which is arranged on one end of the optical lens.

[0010] When in use, this imaging lens cover is placed on one end of the optical lens. Light passes through the optical lens and enters through the light entrance opening. The reflector reflects the light entering from the light entrance opening and then emits it from the window opening, so that the user can see the image of the area facing the camera at the window opening.

[0011] This imaging lens cap provides an image of the area facing the camera through the window opening when the user is not carrying the camera, making it easier for users to select lenses. Users can also control the image through the window opening by adjusting the focus ring on the lens, allowing them to experience the lens. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The imaging lens cover of one embodiment shown includes a cylindrical side wall 10 and a top cover 20. The cylindrical side wall 10 and the top cover 20 form a cavity. The cavity has a light entrance opening 12 opposite to the top cover 20. A reflector 30 is provided in the cavity. The cylindrical side wall 10 has a window opening 14.

[0020] The reflector 30 forms an angle with the axis of the cylindrical sidewall 10 . The reflector 30 reflects the light incident from the light incident opening 12 and emits the light from the viewing window opening 14 .

[0021] This imaging lens cover is placed on one end of the optical lens when in use. Figure 4After passing through the optical lens, light enters through the light entrance opening 12 , and the reflector 30 reflects the light entering from the light entrance opening 12 and then emits it from the window opening 14 , so that the user can see the image of the area facing the camera at the window opening 14 .

[0022] This imageable lens cover can provide an image of the area facing the camera at the window opening 14 when the user is not carrying a camera, making it easier for the user to select a lens. The user can also control the image at the window opening 14 by adjusting the focus ring on the lens, thereby achieving the purpose of experiencing the lens.

[0023] It should be noted that Figure 4 The dashed line with an arrow in the middle is the direction of the light.

[0024] Preferably, the included angle between the reflector 30 and the axis of the cylindrical side wall 10 is 40° to 50°.

[0025] More preferably, the included angle between the reflector 30 and the axis of the cylindrical side wall 10 is 44° to 46°.

[0026] Specifically, those skilled in the art should understand that when the included angle between the reflector 30 and the axis of the cylindrical side wall 10 is 45°, the imaging effect is the best, but a slight deviation will not cause much impact.

[0027] In this embodiment, the cylindrical side wall 10 is cylindrical so as to match the optical lens.

[0028] In this embodiment, the reflector 30 is a plane mirror.

[0029] With reference to the accompanying drawings, preferably, in this embodiment, a transparent plate 40 is provided at the window opening 14 .

[0030] Obviously, the angle between the transparent plate 40 and the reflector 30 is also 44° to 46°.

[0031] A transparent plate 40 is provided at the window opening 14 so that the light reflected by the reflector 30 can be imaged on the transparent plate 40 , thereby further improving the user experience.

[0032] Since the lenses in the optical lens are all circular, the image formed on the transparent plate 40 after the light is reflected is circular.

[0033] However, under normal circumstances, the display interface of a camera is generally rectangular, which will cause the imaging experience formed by the imageable lens cover to be too different from that of the camera.

[0034] In order to solve the above problem, in this embodiment, the side of the transparent plate 40 close to the cavity is a frosted glass surface, and the side of the transparent plate 40 away from the cavity is a smooth surface.

[0035] The side of the transparent plate 40 close to the cavity is a frosted glass surface, so that light is diffusely reflected on the frosted glass surface, thereby forming an image that fills the light surface on the light surface.

[0036] Furthermore, in this embodiment, the transparent plate 40 is rectangular, so that the image formed on the transparent plate 40 by the light from the light-transmitting lens is rectangular.

[0037] In this embodiment, the transparent plate 40 is a glass plate. In other embodiments, the transparent plate 40 may be made of other materials.

[0038] With reference to the accompanying drawings, in this embodiment, a snap-fit structure 16 is provided on the inner side of one end of the cylindrical side wall 10 away from the top cover 20 .

[0039] The buckle structure 16 enables the imageable lens cover to be fixed to one end of the optical lens.

[0040] In this embodiment, there are four snap-fit structures 16. In other embodiments, the number of snap-fit structures 16 can be set according to actual needs.

[0041] With reference to the accompanying drawings, in this embodiment, the sidewall of the window opening 14 away from the cavity forms a chamfer 18. The chamfer 18 can improve the user's touch feeling and avoid being scratched or bumped.

[0042] In other embodiments, the bevel chamfer 18 may also be configured as an arc-shaped chamfer.

[0043] The invention also discloses an optical lens assembly, comprising an optical lens and the above-mentioned imageable lens cover which is arranged on one end of the optical lens.

[0044] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
