Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories, and in particular to a lens protective case. Background Technology

[0002] Smartphones are currently the most frequently used digital devices in daily life. Due to their relatively high value, and to mitigate wear and tear and prevent damage from accidental bumps, smartphones are generally equipped with corresponding phone cases to protect their bodies. To avoid affecting camera performance, most phone cases have a notch corresponding to the smartphone's camera lens. Therefore, the outward-facing end of the camera lens protrudes from the case, making it susceptible to damage. Some manufacturers have therefore added lens protectors or lens cases to the area corresponding to the camera lens for waterproofing and dustproofing. However, current lens cases are integrated with the phone case. After a period of use, due to deformation of the phone case, a large gap can form between the lens case and the smartphone lens, drastically reducing the protective effect. Other manufacturers have therefore produced lens cases as separate accessories. However, the current lens cases are not securely attached to the smartphone lens and are prone to detachment.

[0003] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a lens protective shell that can be securely fixed to the lens.

[0005] The lens protective housing provided by this utility model includes a sealing member and a positioning part for positioning the lens; the positioning part includes a positioning section disposed toward the end face of the lens and a protective section extending from the edge of the positioning section toward the end face of the lens toward one end toward the lens; a mounting groove is also provided between the two ends of the protective section; the sealing member is disposed in the mounting groove, and the sealing member is used to seal the gap between the circumferential surface of the lens and the protective section.

[0006] Compared with existing technologies, the lens protective case provided by this utility model has a sealing element and a positioning portion for positioning the lens. The positioning portion has a positioning section facing the end face of the lens to support the end face of the lens. The positioning portion also has a protective section extending from the edge of the positioning section facing the end face of the lens towards one end facing the lens to surround the circumferential surface of the lens. A mounting groove is provided between the two ends of the protective section. The sealing element is disposed within the mounting groove to seal the gap between the circumferential surface of the lens and the protective section. Simultaneously, the mutual compression between the sealing element and the lens further ensures a secure fixation. Therefore, the lens protective case of this utility model can reliably fix to the lens portion of a smartphone and has good waterproof and dustproof performance.

[0007] Specifically, the positioning section, the protective section, and the mounting groove are integrally formed. This design results in a seamless and connection-free positioning portion, leading to higher mechanical strength. Furthermore, this structure offers better dust and water resistance.

[0008] Specifically, a fastening layer for securing the seal is provided between the seal and the mounting groove. This arrangement makes the connection and fit between the seal and the mounting groove tighter, improving reliability in use.

[0009] Specifically, the fastening layer has an intermittent structure. This design allows the seal to be fixedly connected to the mounting groove at multiple points, saving material while ensuring connection strength and thus reducing costs.

[0010] Specifically, the seal has a semi-circular or flat D-shaped cross-section, and its plane is fixedly connected to the mounting groove. This design allows the seal to fit better into the mounting groove, facilitating its positioning within the groove.

[0011] Specifically, the seal extends beyond the mounting groove, and the extension length of the seal is H, where 0.2mm ≤ H ≤ 0.5mm. This design ensures that the seal is not over-compressed during operation, thus extending its service life. Simultaneously, the moderate compression facilitates the installation of the lens protective housing onto the lens, improving ease of use.

[0012] Specifically, the seal is an elastic member that elastically expands and contracts between the circumferential surface of the lens and the mounting groove.

[0013] Specifically, the end face of the positioning segment away from the lens has an outwardly extending flange, which together with the positioning segment forms an installation step.

[0014] Specifically, a protective film is provided on the mounting step to protect the end face of the lens. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0024] Please see Figures 1 to 5This utility model provides a lens protective housing 100, including a sealing member 1 and a positioning portion 2 for positioning a lens 200. The positioning portion 2 includes a positioning section 21 facing the end face of the lens 200 and a protective section 22 extending from the edge of the positioning section 21 facing the end face of the lens 200 toward the end facing the lens 200. A mounting groove 23 is also provided between the two ends of the protective section 22; the sealing member 1 is disposed in the mounting groove 23, and the sealing member 1 is used to seal the gap between the circumferential surface of the lens 200 and the protective section 22. The end face of the positioning section 21 away from the lens 200 has an outwardly extending flange 24, and the flange 24 and the positioning section 21 together form a mounting step 20. A protective film 25 for protecting the end face of the lens 200 is provided on the mounting step 20. Specifically, to ensure seamlessness and connection points in the positioning portion 2, thereby improving mechanical strength and dust and water resistance, the positioning section 21, the protective section 22, and the mounting groove 23 are integrally formed. The sealing element 1 is an elastic member, capable of elastically expanding and contracting between the circumferential surface of the lens 200 and the mounting groove 23. In this embodiment, the sealing element 1 is a sealing ring, the lens protective shell 100 is approximately annular, and the diameter of the flange 24 is smaller than the diameter of the positioning section 21, thus forming a mounting step 20 with sufficient mounting area to accommodate the protective film 25. It is understood that the lens protective shell 100 can also be square or a combination of square and annular shapes; this is an adaptive modification based on the lens shape, easily conceived by those skilled in the art, and will not be described in detail here. Similarly, the protective film 25 uses existing lens protective films that do not affect the photographing function, and will not be elaborated upon here.

[0025] Further, please refer to Figures 3 to 4 A fastening layer 3 for fixing the seal 1 is provided between the seal 1 and the mounting groove 23. This arrangement makes the connection and fit between the seal 1 and the mounting groove 23 tighter, improving the reliability of use. Specifically, the fastening layer 3 has an intermittent structure. This arrangement allows the seal 1 to be fixedly connected to the mounting groove 23 at multiple points, which can save materials while ensuring connection strength, thereby saving costs. In this example, the seal 1 is fixed by a dispensing process, with the adhesive applied in discrete dots, lines, or intervals to form a discontinuous fastening layer 3. This arrangement also prevents the adhesive from overflowing into the mounting groove 23, reducing adhesive waste and avoiding the need for subsequent additional adhesive removal steps.

[0026] Further, please refer to Figure 4The seal 1 has a semi-circular or flat D-shaped cross-section, thus including a curved surface 11 and a flat surface 12. The flat surface 12 of the seal 1 is connected and fixed to the mounting groove 23, while the curved surface 11 of the seal 1 faces the circumferential surface of the lens 200. This arrangement allows the seal 1 to fit better into the mounting groove 23, facilitating its positioning and placement, thereby improving the efficiency of installing and fixing the seal 1.

[0027] Further, please refer to Figure 4 The sealing element 1 extends beyond the mounting groove 23, and the extension length of the sealing element 1 is H, where 0.2mm ≤ H ≤ 0.5mm. In this embodiment, H = 0.3mm. At this point, the curved surface 12 of the sealing element 1 has a moderate amount of elastic compression when pressed against the circumferential surface of the lens 200. This ensures sufficient elastic force while preventing excessive compression of the sealing element 1 during operation, thus extending its service life. Simultaneously, the moderate compression also facilitates the installation of the lens protective housing 100 onto the lens 200, improving ease of use.

[0028] The following is a description of the working principle of the lens protective housing 100 provided by this utility model. In use, the lens protective housing 100 is first fitted onto the circumferential surface of the lens 200 for initial positioning. At this time, the protective section 22 of the lens protective housing 100 covers part of the circumferential surface of the lens 200. Then, the lens protective housing 100 is pushed axially, and the sealing element 1 of the lens protective housing 100 gradually approaches the lens 200. When the lens 200 contacts the sealing element 1, there will be a relatively obvious resistance. At this time, a little more pushing force is needed to compress the sealing element 1 between the mounting groove 23 and the circumferential surface of the lens 200. Finally, the pushing continues until the positioning section 21 of the lens protective housing 100 abuts against the annular surface of the lens 200 and the end face of the lens 200. At this point, the installation of the lens protective housing 100 is completed.

[0029] Compared with the prior art, the lens protective housing 100 provided by this utility model has a sealing member 1 and a positioning portion 2 for positioning the lens 200. The positioning portion 2 has a positioning section 21 facing the end face of the lens 200 to support the end face of the lens 200. The positioning portion 21 also has a protective section 22 extending from the edge of the positioning section 21 facing the end face of the lens 200 towards one end facing the lens 200 to surround the circumferential surface of the lens 200. A mounting groove 23 is provided between the two ends of the protective section 22. The sealing member 1 is disposed within the mounting groove 23 to seal the gap between the circumferential surface of the lens 200 and the protective section 22. Simultaneously, the mutual compression between the sealing member 1 and the lens 200 further ensures a secure fixation. Therefore, the lens protective housing of this utility model can be reliably fixed to the lens portion of a smartphone and has good waterproof and dustproof performance.

[0030] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
