Technical issues

[0003] Therefore, it is necessary to provide a new lens device and electronic equipment to solve the above technical problems. Technical Solutions

[0004] The purpose of this application is to provide a lens device and electronic device to solve the technical problem that the radial size of the front lens of the current mobile phone is usually large, which makes it impossible for the front lens of the mobile phone to be hidden in the black edge of the screen, resulting in the inability to achieve a truly full-screen display.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0041] In the description of this application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0042] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0043] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0044] An embodiment of the present application provides an electronic device, which may be a mobile terminal such as a mobile phone or tablet computer. Referring to Figures 2 to 12 , the electronic device includes a housing 30, a display screen 20, and a lens assembly 10. The display screen 20 includes a display area 22 and a black border 21 disposed outside the display area 22. The black border 21 is a non-display area. A lens opening 23 is provided on the display screen 20, opposite to the lens assembly 10. The lens opening 23 is located on a side of the display screen 20, and at least a portion of the lens opening 23 is located within the black border 21. This reduces the size of the lens opening 23 within the display area 22, or even allows the lens opening 23 to be completely disposed within the black border 21, thereby achieving a full-screen electronic device.

[0045] The lens device 10 includes a first lens group 100, a second lens group 200, and a prism 300. The optical axes of the first lens group 100 and the second lens group 200 are arranged at an angle. The optical path of the first lens group 100 is arranged closer to the object side than the optical path of the second lens group 200. The prism 300 is arranged between the first lens group 100 and the second lens group 200 and is used to fold the optical path.

[0046] It is understandable that, in the prior art installation of a camera device on an electronic device, as shown in FIG1 , the size of D / 2 in FIG1 is relatively large, making it inconvenient to hide the camera device within the black border 21 of the display screen 20 .

[0047] Since the present embodiment disposes the prism 300 between the first lens group 100 and the second lens group 200, the use of the prism 300 to refract the optical path can reduce the height of the lens device 10, which is more conducive to the lightweight and thinning of the electronic device. The lens device 10 is split into the first lens group 100 and the second lens group 200. Since the radial dimension of the first lens group 100 close to the object side is smaller than the radial dimension of the second lens group 200, as shown in Figures 2 and 3, the dimension of Y / 2 in the figures is greatly reduced, thereby reducing the installation dimension adapted to the display screen 20, thereby better hiding the lens device 10 within the black border 21 of the display screen 20, thereby increasing the size of the display area 22 on the display screen 20, further facilitating the full-screen design of the display screen 20 and providing a better user experience.

[0048] Furthermore, in this embodiment, a shearing edge is provided on the edge of at least one lens in the first lens group 100 and the second lens group 200, thereby reducing the radial size of the lenses in the lens group, thereby further reducing the radial size of the first lens group 100 and the second lens group 200. Please refer to Figures 2 and 3. The size of H in the figures is greatly reduced, thereby further reducing the installation size compatible with the display screen 20, ensuring that the lens device 10 can be closer to or even hidden in the black border 21 of the display screen 20.

[0049] In one embodiment, referring to Figures 2 and 3, the optical axis of the first lens assembly 100 is perpendicular to the display screen 20 and is disposed close to the inner wall of the display screen 20 and the inner wall of the housing 30. This reduces the installation dimensions of the first lens assembly 100, the display screen 20, and the housing 30, thereby better concealing the lens device 10 within the black border 21 of the display screen 20.

[0050] Furthermore, in this embodiment, the optical axes of the first lens assembly 100 and the second lens assembly 200 are arranged perpendicularly, thereby facilitating the installation of the lens assembly 10 within the housing 30 and the display screen 20, and further facilitating the slimming and lightweight design of the electronic device. Specifically, the electronic device may be a mobile phone, thereby facilitating a full-screen design and a slimming and lightweight design of the mobile phone.

[0051] Of course, in some embodiments, the optical axis of the first lens group 100 may be set at an acute angle or an obtuse angle with the display screen 20 , and the optical axis of the first lens group 100 may be set at an acute angle or an obtuse angle with the optical axis of the second lens group 200 .

[0052] In one embodiment, please continue to refer to Figures 2 and 3. The first lens group 100 includes a first lens barrel 110 and a plurality of first lenses 120 disposed in the first lens barrel 110. Each first lens 120 is installed in the first lens barrel 110 to facilitate the integrated assembly of each first lens 120.

[0053] In this embodiment, the second lens assembly 200 includes a second lens barrel 210 and a plurality of second lenses 220 disposed in the second lens barrel 210 . Each second lens 220 is installed in the second lens barrel 210 to facilitate the integrated assembly of each second lens 220 .

[0054] Furthermore, the prism 300 is disposed in the second lens barrel 210 , and the first lens barrel 110 is bonded to the second lens barrel 210 by adhesive 410 , so that the optical axes of the first lens group 100 and the second lens group 200 are arranged at a preset angle.

[0055] By adjusting the bonding position of the first lens barrel 110 and the second lens barrel 210 , the angle between the optical axes of the first lens group 100 and the second lens group 200 can be adjusted, thereby facilitating the assembly of the first lens group 100 and the second lens group 200 .

[0056] In this embodiment, three first lenses 120 are provided and two second lenses 220 are provided, so that the lens device 10 is configured as a five-lens module. By setting fewer lenses, the height and radial size of the lens module can be reduced, which is more conducive to the miniaturization and thinness of electronic equipment.

[0057] Of course, in some embodiments, the number of the first lens 120 may be one, two, four or more, and the number of the second lens 220 may be one, three or more, so that the lens device 10 can be configured as a six-lens module, a seven-lens module, etc. as needed.

[0058] In one embodiment, referring to FIG. 3 , the prism 300 is an aspherical prism 300 . By adding an aspherical surface 311 to the prism 300 , the optical performance of the lens device 10 can be improved.

[0059] Furthermore, the prism 300 includes a first optical surface 310 and a second optical surface 320 that are perpendicular to each other, and a third optical surface 330 that is set at an acute angle to the first optical surface 310 and the second optical surface 320, and at least one of the first optical surface 310 and the second optical surface 320 is formed with an aspherical surface 311.

[0060] Specifically, the first optical surface 310 is coaxially disposed with the optical axis of the first lens barrel 110 , the second optical surface 320 is coaxially disposed with the optical axis of the second lens barrel 210 , and the aspheric surface 311 is formed on the first optical surface 310 .

[0061] Of course, in other embodiments, referring to FIG. 2 , the prism 300 may also be a plane prism 300, that is, the first optical surface 310 and the second optical surface 320 are both flat optical surfaces, or the second optical surface 320 of the prism 300 is an aspherical surface 311. The optical surface setting in the prism 300 may be configured according to the design requirements of the lens module to ensure the optical performance of the device.

[0062] In one embodiment, referring to Figures 6 and 7, 10 and 11, at least one of the first lenses 120 is provided with a first cut edge 101 and a second cut edge 102 arranged opposite to each other, and at least one of the second lenses 220 is provided with a third cut edge 201 and a fourth cut edge 202 arranged opposite to each other, thereby facilitating a reduction in the radial size of the lenses in the lens group, thereby further reducing the radial size of the first lens group 100 and the second lens group 200, and thus further reducing the installation size adapted to the display screen 20.

[0063] In this embodiment, each lens in the first lens group 100 and each lens in the second lens group 200 has a variety of edge cutting schemes to adapt to the installation requirements of the lens device 10 on the electronic device.

[0064] In a specific embodiment, referring to Figures 10 and 11, the first lens group 100 is configured with three first lenses 120, namely, lens 121, lens 122, and lens 123. Lens 121, lens 122, and lens 123 are all provided with first and second cut edges 101 and 102 relative to each other. The second lens group 200 is configured with two second lenses 220, namely, lens 221 and lens 222. Lens 221 has a third cut edge 201 on one side, and lens 222 has a third cut edge 201 and a fourth cut edge 202 relative to each other. This reduces the radial dimensions of each lens, further facilitating a slimmer lens device 10. Furthermore, it can reduce the installation dimensions of the first lens group 100, the display screen 20, and the housing 30, thereby better concealing the lens device 10 within the black border 21 of the display screen 20.

[0065] In another specific embodiment, the first lens group 100 is configured with three first lenses 120, namely, lens 121, lens 122, and lens 123. The first lens 121, lens 122, and lens 123 are all provided with a first cut edge 101 and a second cut edge 102 relative to each other. The second lens group 200 is configured with two second lenses 220, namely, lens 221 and lens 222. The second lens 221 and lens 222 are all provided with a third cut edge 201 and a fourth cut edge 202 relative to each other. This reduces the radial dimension of each lens, further facilitating a lightweight and thin lens device 10. At the same time, it can also reduce the installation dimensions of the first lens group 100, the display screen 20, and the housing 30, thereby better concealing the lens device 10 within the black border 21 of the display screen 20.

[0066] In another specific embodiment, the first lens group 100 is configured with three first lenses 120, namely, lens 11 121, lens 122 122, and lens 13 123. The lens 11 121, lens 122, and lens 13 123 are all provided with first and second cut edges 101 and 102 relative to each other. The second lens group 200 is configured with three second lenses 220, namely, lens 21 221, lens 222, and lens 33. The lens 21 221, lens 222, and lens 33 are all provided with third and fourth cut edges 201 and 202 relative to each other. This reduces the radial dimensions of each lens, further facilitating a slimmer lens device 10. Furthermore, it can reduce the installation dimensions of the first lens group 100, the display screen 20, and the housing 30, thereby better concealing the lens device 10 within the black border 21 of the display screen 20.

[0067] Of course, in other embodiments, each lens in the lens device 10 may also have other shearing edge solutions. For example, referring to Figures 6 and 7, the first lens group 100 is configured with three first lenses 120, namely, lens 11 121, lens 122, and lens 123. Among them, lens 11 121, lens 122, and lens 123 are all provided with first shearing edges 101 and second shearing edges 102 relative to each other. The second lens group 200 is configured with two second lenses 220, namely, lens 21 221 and lens 222. Both lens 21 221 and lens 222 are provided with shearing edges, thereby ensuring the optical performance of the lens device 10. Therefore, it should be noted that the premise for shearing each lens in the lens device 10 to minimize the size of the first lens group 100 and the second lens group 200 in the lens device 10 is to minimize the optical performance of each lens in the lens device 10.

[0068] In one embodiment, referring to Figures 2 and 3, a first step hole 111 is provided in the first lens barrel 110, and each of the first lenses 120 is respectively received in the step hole wall of the first step hole 111. The second lens barrel 210 is provided with a second step hole 211, and each of the second lenses 220 is respectively received in the step hole wall of the second step hole 211. The second lens barrel 210 is further provided with a receiving groove 212 connected to the second step hole 211, and the prism 300 is received in the receiving groove 212, thereby realizing the installation of each first lens 120, each second lens 220, and the prism 300.

[0069] In one embodiment, referring to Figures 2 to 5, 8, and 9, the second lens barrel 210 is provided with a notch 213, and the first lens barrel 110 is accommodated in the notch 213, thereby facilitating the miniaturization of the lens device 10. Specifically, a plurality of light shielding plates 420 are further provided within the first lens group 100 and the second lens group 200. Each light shielding plate 420 is installed between two adjacent lens elements. At the same time, each light shielding plate 420 is adaptively trimmed along with each lens element. Furthermore, an optical lens 230 is further provided within the second lens group 200. The optical lens 230 is used to confine each second lens element 220 within the second lens barrel 210.

[0070] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
