Lens protective cases and electronic devices

Abstract

This invention proposes a lens protective housing and electronic device, comprising: a protective tube configured to surround a lens, the protective tube having a lens aperture, a mounting groove, and a protective hole, the lens aperture, mounting groove, and protective hole being sequentially arranged from bottom to top along the height direction of the protective tube and connected sequentially; the lens aperture for exposing the lens; the mounting groove surrounding the lens aperture; and the protective hole surrounding the mounting groove; and a transparent protective plate disposed in the mounting groove, covering the lens aperture. In this lens protective housing, because the mounting groove is located below the protective hole, the mounting groove is a recessed structure that sinks downwards relative to the top surface of the protective tube. Therefore, when the transparent protective plate is installed in the mounting groove, the transparent protective plate also sinks downwards relative to the top surface of the protective tube. Consequently, if the lens falls downwards, only the top surface of the protective tube will touch the ground, preventing the transparent protective plate from touching the ground and thus preventing breakage, resulting in improved durability.

Description

Lens protective cases and electronic devices Technical Field

[0001] This invention relates to a protective case, and more particularly to a lens protective case and electronic devices. Prior Technology

[0002] With the increasing sophistication of mobile phone technology, mobile phones, including their camera components, are typically exposed on the outside of the phone's casing to enable proper shooting. This makes them susceptible to scratches, impacts, and breakage. Consequently, lens cases have emerged to protect camera components. These cases attach directly to the lens, protecting it and reducing the risk of damage. However, current lens cases often include a transparent protective layer, usually made of glass. This transparent layer is prone to shattering upon impact with the ground after a drop, making current lens cases less durable. Summary of the Invention

[0003] This application provides a lens protective case and an electronic device to solve the problems existing in related technologies. The technical solution is as follows:

[0004] This application provides a lens protective housing, comprising: a protective tube configured to surround a lens, the protective tube having a lens hole, a mounting groove, and a protective hole, the lens hole, the mounting groove, and the protective hole being sequentially arranged from bottom to top along the height direction of the protective tube and being sequentially connected, the lens hole being for exposing the lens, the mounting groove being arranged around the lens hole, and the protective hole being arranged around the mounting groove; a transparent protective plate disposed in the mounting groove, the transparent protective plate covering the lens hole.

[0005] In one embodiment, the transparent protective plate is a structure made of anti-reflective glass.

[0006] In one embodiment, the transparent protective plate has two layers of AR film.

[0007] In one embodiment, the mounting groove has a straight groove structure, and the outer contour shape of the transparent protective plate is adapted to the mounting groove.

[0008] In one embodiment, the cross-section of the protective hole gradually increases from bottom to top.

[0009] In one embodiment, the lower end of the protective hole contacts the top surface of the transparent protective plate.

[0010] In one embodiment, the protective sleeve also has a receiving hole located below and surrounding the lens hole for receiving a lens.

[0011] In one embodiment, the top outer peripheral wall of the protective cylinder is provided with a tapered portion, the cross-section of which gradually decreases from bottom to top.

[0012] In one embodiment, the depth of the protective hole is 0.002 mm to 1.6 mm.

[0013] Secondly, embodiments of this application provide an electronic device including the aforementioned lens protective housing.

[0014] The advantages or beneficial effects of the above technical solution include at least the following: Because the mounting groove of this lens protective housing is located below the protective hole, the mounting groove is a recessed structure that sinks downwards relative to the top surface of the protective cylinder. Therefore, when the transparent protective plate is installed in the mounting groove, the transparent protective plate also sinks downwards relative to the top surface of the protective cylinder, that is, the transparent protective plate is recessed inwards relative to the top surface of the protective cylinder. Consequently, if the lens falls downwards, only the top surface of the protective cylinder will touch the ground, preventing the transparent protective plate from touching the ground, thus preventing the transparent protective plate from breaking and improving durability. Furthermore, because the main housing of this lens protective housing is composed of components surrounding the lens… The independent protective sleeve is compact and small in size. During assembly, it can be simply mounted around the lens onto the electronic device, making it easier to achieve a tight connection between the protective sleeve and the electronic device. This also makes it easier to control the installation stability of the protective sleeve, making it less likely to separate from the electronic device after the lens is dropped, thus providing a higher level of protection for the lens. In addition, the independent protective sleeve is easier to control the processing precision during manufacturing, thereby improving the molding quality of the protective sleeve. When this lens protective shell is installed around the lens, it can protect the lens shape to a greater extent, achieving a high level of lens protection, and its appearance is more aesthetically pleasing, improving the user's visual comfort.

[0015] The electronic device of this invention also has the aforementioned advantages due to the use of the lens protective shell.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] Referring to Figures 1 to 5, a preferred embodiment of the present invention is shown, comprising: a protective tube 1 configured to surround a lens, the protective tube 1 having a lens hole 11, a mounting groove 12 and a protective hole 13, the lens hole 11, the mounting groove 12 and the protective hole 13 being coaxial, the lens hole 11, the mounting groove 12 and the protective hole 13 being arranged sequentially from bottom to top along the height direction of the protective tube 1 and being sequentially connected, the lens hole 11 being used to expose the lens, the mounting groove 12 being arranged around the lens hole 11, and the protective hole 13 being arranged around the mounting groove 12; and a transparent protective plate 2 disposed in the mounting groove 12, the transparent protective plate 2 covering the lens hole 11.

[0025] In this lens protective housing, because the mounting groove 12 is located below the protective hole 13, the mounting groove 12 is a recessed structure that sinks downward relative to the top surface of the protective cylinder 1. Therefore, when the transparent protective plate 2 is installed in the mounting groove 12, the transparent protective plate 2 also sinks downward relative to the top surface of the protective cylinder 1. That is, the transparent protective plate 2 is recessed inward relative to the top surface of the protective cylinder 1. Thus, if the lens falls downward, only the top surface of the protective cylinder 1 will touch the ground, preventing the transparent protective plate 2 from touching the ground. This prevents the transparent protective plate 2 from breaking and improves its durability. In addition, Because the main housing of this lens protective case is formed by an independent protective cylinder 1 surrounding the lens, the protective cylinder 1 has a compact structure and small size. During assembly, it can be assembled around the lens onto the electronic device, making it easier to achieve a tight connection between the protective cylinder 1 and the electronic device. This makes it easier to control the installation stability of the protective cylinder 1, making it less likely to separate from the electronic device after the lens is dropped, thus providing a higher level of protection for the lens. In addition, the independent protective cylinder 1 is easier to control the processing precision during manufacturing, thereby improving the molding quality of the protective cylinder 1. When the lens protective case is installed around the lens, it can protect the shape of the lens to a greater extent, achieving a high level of lens protection, and the appearance is more aesthetically pleasing, improving the user's visual comfort.

[0026] In one embodiment, the transparent protective plate 2 is made of anti-reflective glass. The anti-reflective glass material enhances light transmittance and visual effects, thereby maintaining the original shooting performance of the lens to a greater extent. Simultaneously, the transparent protective plate 2 has better fingerprint resistance, keeping its outer surface clean and ensuring the lens maintains its original shooting performance. Of course, in other embodiments, the transparent protective plate 2 can also be made of plastic or other suitable materials.

[0027] In one embodiment, the transparent protective plate 2 has two layers of AR film. The transparent protective plate 2 with two layers of AR film has better anti-reflective and anti-fingerprint effects, and is less expensive, which helps to reduce the cost of the lens protective shell. Of course, in other embodiments, the transparent protective plate 2 may have a single layer or three or more layers of AR film.

[0028] Referring to Figure 5, in one embodiment, the mounting groove 12 is a straight groove structure, meaning the groove width is equal everywhere. The outer contour shape of the transparent protective plate 2 is adapted to the mounting groove 12. The mounting groove 12 with a straight groove structure includes a bottom wall and a side wall perpendicular to the bottom wall. When the transparent protective plate 2, whose outer contour shape is adapted to the mounting groove 12, is installed in the mounting groove 12, the bottom of the transparent protective plate 2 is connected to the bottom wall of the mounting groove 12, and the side of the transparent protective plate 2 is connected to the side wall of the mounting groove 12. This greatly increases the contact area between the transparent protective plate 2 and the mounting groove 12, which can increase the installation stability of the transparent protective plate 2. This makes it less likely for the transparent protective plate 2 to detach from the protective tube 1 after the lens is dropped, thereby enhancing the protection effect on the lens. In addition, the manufacturing process of the mounting groove 12 with a straight groove structure is simpler, thus reducing the manufacturing difficulty of the protective tube 1 and reducing the cost of this lens protective shell.

[0029] Of course, in other embodiments, the mounting groove 12 can also be a tapered groove structure with a cross-section that gradually increases from bottom to top. The outer contour shape of the transparent protective plate 2 is adapted to the mounting groove 12. Using this structure can also improve the installation stability of the transparent protective plate 2.

[0030] Referring to Figure 5, in one embodiment, the cross-section of the protective hole 13 gradually increases from bottom to top, that is, the protective hole 13 is an outward-expanding structure. On the one hand, the outward-expanding protective hole 13 can provide the lens with a wider field of view and ensure that it will not block the lens. On the other hand, it is easier to clean and reduces the accumulation of dust.

[0031] Of course, in other embodiments, the protective hole 13 may be a straight hole structure, and the diameter of the protective hole 13 may be larger than the width of the mounting groove 12, so as to avoid blocking the lens.

[0032] In one embodiment, the lower end of the protective hole 13 contacts the top surface of the transparent protective plate 2. This structure improves the aesthetics and enhances user comfort, while also reducing dust accumulation in the gap between the lower end of the protective hole 13 and the top surface of the transparent protective plate 2, making cleaning easier. In other embodiments, the lower end of the protective hole 13 may not contact the top surface of the transparent protective plate 2.

[0033] In one embodiment, the protective sleeve 1 further has a receiving hole 14, which is located below and surrounds the lens hole 11, and is used to receive the lens. When the lens protective shell is installed on the electronic device, the outer surface of the lens fits against the wall of the receiving hole 14. With the above structure, the lens can be protected more effectively, and safety can be improved.

[0034] In one embodiment, a tapered portion 15 is provided on the top outer peripheral wall of the protective cylinder 1, and the cross-section of the tapered portion 15 gradually decreases from bottom to top. That is, the top outer peripheral wall of the protective cylinder 1 has a tapered structure, which makes the top outer peripheral contour of the protective cylinder 1 smooth, thereby ensuring that it will not scratch the hand during use and improving the comfort of use.

[0035] In one embodiment, the depth of the protective hole 13 is 0.002mm to 1.6mm, which is sufficient to allow the transparent protective plate 2 to sink to a suitable position, thereby effectively preventing the transparent protective plate 2 from breaking. Of course, in other embodiments, the depth of the protective hole 13 may be a parameter outside the range of 0.002mm to 1.6mm.

[0036] This invention provides an electronic device in a preferred embodiment, including the aforementioned lens protective housing. Because of the lens protective housing, when the lens is dropped, only the top surface of the protective cylinder 1 will touch the ground, preventing the transparent protective plate 2 from touching the ground, thus preventing the transparent protective plate 2 from breaking and improving durability. Furthermore, since the main housing of the lens protective housing is formed by an independent protective cylinder 1 surrounding the lens, the protective cylinder 1 has a compact structure and small size. During assembly, it can be assembled around the lens onto the electronic device, making it easier to tightly connect the protective cylinder 1 and the electronic device. This makes it easier to control the installation stability of the protective cylinder 1, making it less likely to separate from the electronic device after the lens is dropped, thus providing a higher level of lens protection. In addition, the independent protective cylinder 1 makes it easier to control the processing precision during manufacturing, thereby improving the molding quality of the protective cylinder 1. This allows the lens protective housing to better protect the lens's shape when installed around the lens, achieving high-level lens protection, and also resulting in a more aesthetically pleasing appearance and improved visual comfort for the user.

[0037] The above-described embodiments are merely preferred embodiments for fully illustrating this invention and are not intended to limit the features of this invention. Any re-creation using the technical means and creative principles related to this invention still falls within the scope of the equivalent structural creativity of this invention.
