Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of sealing rings, and in particular to a special-shaped sealing ring, an optical lens, and an electronic product. Background Art

[0002] To meet the IP6K4 protection rating requirements for automotive cameras, lenses typically include molded lenses to reduce costs while ensuring waterproof performance. During the molding process, molded lenses are directly molded with a side-pressure waterproof area. This process, which directly molds the outer edges of the lens to form a stepped side-pressure waterproof area, fails to effectively control the size of the small end radius of the molded lens after molding. When the side-pressure waterproof area of ​​the molded lens is assembled with a conventional circular sealing ring, the ring cannot effectively limit its position. When squeezed by external structures or impacted by frontal airflow or water during waterproof testing, the circular sealing ring can slide down to the small end radius of the molded lens. Excessively large small end radius creates a gap between the circular sealing ring and the molded lens, compromising the sealing ring's waterproof performance. Utility Model Content

DETAILED DESCRIPTION

[0036] The following description of exemplary embodiments of the present application is made in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0037] In the accompanying drawings, the thickness, size, and shape of components have been slightly adjusted for ease of illustration. The accompanying drawings are for illustration only and are not drawn strictly to scale. As used herein, the terms "substantially," "approximately," and similar terms are used to indicate approximations, not degrees, and are intended to account for the inherent variations in measurements or calculations that would be recognized by one of ordinary skill in the art.

[0038] It should also be understood that expressions such as "comprises," "including," "having," "includes," and / or "comprising" are open rather than closed expressions in this specification, indicating the presence of the stated features, elements, and / or components, but do not exclude the presence of one or more other features, elements, components, and / or combinations thereof. In addition, when expressions such as "at least one of..." appear after a list of listed features, they modify the entire list of features rather than just the individual elements in the list. In addition, when describing embodiments of the present application, "may" is used to mean "one or more embodiments of the present application." And, the term "exemplary" is intended to refer to an example or illustration.

[0039] Unless otherwise defined, all words used herein (including engineering terms and scientific and technological terms) have the same meaning as commonly understood by those skilled in the art to which this application belongs. It should also be understood that, unless otherwise specified in this application, words defined in commonly used dictionaries should be interpreted as having the same meaning as they do in the context of the relevant technology, and should not be interpreted in an idealized or overly formal sense.

[0040] It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application may be combined with each other. In addition, unless explicitly limited or inconsistent with the context, the specific steps included in the method described in this application are not necessarily limited to the order described, but may be performed in any order or in parallel.

[0041] To meet the IP6K4 protection rating requirements for automotive cameras, lenses typically include molded lenses to reduce costs while ensuring waterproof performance. During the molding process, molded lenses are directly molded with a lateral pressure waterproofing area. This process, which creates a stepped lateral pressure waterproofing area at the outer edges of the lens, prevents effective control over the size of the small corner radius after molding. For example, the size of the small corner radius is affected by the volume tolerance of the lens material, and molding flash can also cause irregularities in the shape of the small corner radius. When the lateral pressure waterproofing area of ​​the molded lens is assembled with a conventional circular sealing ring, the ring cannot effectively retain the seal. When subjected to external pressure or impact from frontal airflow or water during waterproof testing, the ring can slip onto the small corner radius of the molded lens. Excessive small corner radius can create a gap between the ring and the molded lens, compromising the sealing ring's waterproof performance.

[0042] like Figure 1 As shown, Figure 1The assembly structure of a conventional circular sealing ring 110 and a molded lens G0 is shown. The outer edges of the molded lens G0, at their large and small ends P1 and P2, form a stepped lateral pressure waterproof area on the side S2 of the molded lens G0, where P1 represents the large end and P2 represents the small end. The conventional circular sealing ring 110 is assembled within the lateral pressure waterproof area of ​​the molded lens G0. In this lateral pressure waterproof area, the circular sealing ring 110 is squeezed by the lens barrel 120 and the outer surface of the small end of the molded lens G0, forming a sealing ring compression area that meets waterproofing requirements. When squeezed by external structures or impacted by front airflow or water flow during a waterproofing test, the circular sealing ring 110 can slide down to the small end rounded corner A on the side S2 of the molded lens G0. If the small end rounded corner A is too large, a gap will form in the sealing ring compression area 130 between the circular sealing ring 110 and the molded lens G0, affecting the waterproofing performance of the circular sealing ring 110.

[0043] In order to solve the above problems, an embodiment of the present application provides a special-shaped sealing ring 200.

[0044] Figure 2 FIG. 2 shows the assembly structure of the special-shaped sealing ring 200 and the lens G1 according to the embodiment of the present application. Figure 2 As shown, the special-shaped sealing ring 200 of the embodiment of the present application may include: a sealing ring body 210 and a sealing ring tail 220 connected to the sealing ring body 210. The special-shaped sealing ring 200 can be used as a waterproof sealing ring for the lens G1, and is assembled in the side pressure waterproof area on the outer edge of the lens G1. For example, the special-shaped sealing ring 200 is assembled on the step on the outer edge of the lens G1. The special-shaped sealing ring 200 can be located between the lens barrel 230 and the lens G1 installed in the lens barrel 230. The sealing ring body 210 is interference fit with the outer edge of the lens barrel 230 and the lens G1. The sealing ring body 210 will be squeezed by the outer circumferential surface of the lens barrel 230 and the outer edge of the lens G1, forming a sealing ring compression area to meet the waterproof requirement. The sealing ring tail portion 220 is tightly fitted with an element 240 installed adjacent to the lens G1 within the lens barrel 230. The sealing ring tail portion 220 can abut against the adjacent element 240, restricting the position of the special-shaped sealing ring 200 within the lateral pressure waterproof area. This prevents the special-shaped sealing ring 200 from sliding off when subjected to squeezing or impact forces, thereby ensuring the waterproof performance of the special-shaped sealing ring 200. For example, when the lens G1 is a molded lens G0, the special-shaped sealing ring 200 can be prevented from sliding off to the small end rounded corner A of the molded lens G0 on the side surface S2 when subjected to squeezing or impact forces. In this application, a tight fit can refer to a fit with zero clearance, a fit with relatively small clearance, or a tight fit.

[0045] The shaped sealing ring 200 of the embodiment of the present application improves the sealing ring structure itself, with the sealing ring body 210 meeting waterproof requirements through an interference fit, and the sealing ring tail 220 ensuring waterproof performance through a press fit. This can be used to improve the waterproof failure problem caused by the sealing ring slipping due to squeezing or impact forces on the lens G1. Therefore, in the embodiment of the present application, the sealing ring body 210 that performs the waterproof function of the shaped sealing ring 200 can also be referred to as the waterproof portion, and the sealing ring tail 220 that performs the limiting function can be referred to as the limiting portion. The shaped sealing ring 200 of the embodiment of the present application can not only meet the requirements of the IP6K4 protection level, but also meet the requirements of higher protection levels such as IP6K9.

[0046] It should be noted that the material, type, and parameters of the lens G1 used to assemble the special-shaped sealing ring 200 in the embodiments of the present application, as well as the material, structure, and dimensions of the lens barrel 230 in which the lens G1 is mounted, can be determined based on the specific application scenario and are not limited in the embodiments of the present application. For example, the lens barrel 230 can be the lens barrel of a waterproof lens, and the lens G1 can be the first lens mounted on the object side of the lens barrel of the waterproof lens. The lens barrel 230 can be made of metal or plastic, and the lens G1 can be made of glass or plastic.

[0047] It should be noted that in the embodiments of the present application, the type of element 240 installed adjacent to lens G1 within lens barrel 230 can be determined based on the specific application scenario, and the embodiments of the present application are not limited thereto. For example, lens barrel 230 and lens G1 can be a lens barrel of a waterproof lens and a first lens installed on the object side of the lens barrel, and element 240 installed adjacent to lens G1 within lens barrel 230 can be a light shielding sheet or an optical lens.

[0048] It should be noted that in the embodiments of the present application, the material and shape of the sealing ring body 210, the material and shape of the sealing ring tail 220, and the connection method of the sealing ring body 210 and the sealing ring tail 220 can be determined according to the specific application scenario, and the embodiments of the present application do not limit this. Among them, the sealing ring body 210 and the sealing ring tail 220 can be made of the same material or different materials. For example, the sealing ring body 210 and the sealing ring tail 220 can both be made of rubber or silicone, and the sealing ring body 210 and the sealing ring tail 220 can be integrally formed.

[0049] In some optional embodiments of the present application, the sealing ring body 210 can be connected to one end of the sealing ring tail 220, and the other end of the sealing ring tail 220 can be pressed and matched with the adjacent installed component 240. That is, the special-shaped sealing ring 200 is divided into left and right parts, for example, Figure 2As shown, the left side of the parting line 250 is the sealing ring body 210, and the right side of the parting line 250 is the sealing ring tail 220. Optionally, the portion of the sealing ring body 210 not connected to the sealing ring tail 220 can be a conventional structure, for example, the portion of the sealing ring body 210 not connected to the sealing ring tail 220 can have an arc surface 211.

[0050] It should be noted that the use of the parting line 250 to separate the shaped sealing ring 200 in this application is merely for the convenience of distinguishing the sealing ring body 210 from the sealing ring tail 220 and does not constitute a limitation on the basis for distinguishing the sealing ring body 210 from the sealing ring tail 220. Those skilled in the art should be aware that when a mold for a product is spliced ​​together, the small gaps at the joints create small edge protrusions during product pouring, forming parting lines on the product surface. The position of the parting line is related to the mold structure and the product structure. Therefore, when the shaped sealing ring 200 is integrally molded, the parting line can be formed between the sealing ring body 210 and the sealing ring tail 220, or the parting line can be formed only on the sealing ring body 210, or the parting line can be formed only on the sealing ring tail 220.

[0051] In some optional embodiments of the present application, at least a portion of the portion of the sealing ring body 210 not connected to the sealing ring tail 220 has a curvature, the end of the sealing ring tail 220 that is pressed against the adjacent component 240 is flat or has at least a portion that has a curvature, and the sealing ring tail 220 further has an inner ring side surface 222 and an outer ring side surface 223 that connect the sealing ring body 210 and the end that is pressed against the adjacent component 240. The portion of the sealing ring body 210 not connected to the sealing ring tail 220 can have a circular arc surface or a wavy surface, and the embodiments of the present application are not limited to this. The end of the sealing ring tail 220 that is pressed against the adjacent component 240 can have a flat surface, a circular arc surface, or a wavy surface, and the embodiments of the present application are not limited to this.

[0052] In some optional embodiments, such as Figure 2 As shown, the portion of the sealing ring body 210 not connected to the sealing ring tail 220 has an arcuate surface 211. The end of the sealing ring tail 220, which is press-fitted with the adjacent component 240, is a flat surface 221. The sealing ring tail 220 also has an inner ring side surface 222 and an outer ring side surface 223 connecting the arcuate surface 211 and the flat surface 221. The inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail 220 each have an inclination angle with the axis of the special-shaped sealing ring 200. The inner ring side surface 222 and the outer ring side surface 223 can have the same inclination angle with the axis of the special-shaped sealing ring 200, or different inclination angles.

[0053] It should be noted that the embodiments of the present application do not limit the forms of the inner ring side surface 222 and the outer ring side surface 223. For example, when the inclination angle between the inner ring side surface 222 and / or the outer ring side surface 223 and the axis of the special-shaped sealing ring 200 is 0°, the inner ring side surface 222 and / or the outer ring side surface 223 are parallel to the axis of the special-shaped sealing ring 200, and the inner ring side surface 222 and / or the outer ring side surface 223 are cylindrical. For another example, when the inclination angle between the inner ring side surface 222 and / or the outer ring side surface 223 and the axis of the special-shaped sealing ring 200 is not 0°, the inner ring side surface 222 and / or the outer ring side surface 223 are inclined relative to the axis of the special-shaped sealing ring 200, and the inner ring side surface 222 and / or the outer ring side surface 223 are conical surfaces, such as Figure 2 As shown, the conical surface may refer to a rotating surface that connects the arc surface 211 and the outer edge of the plane 221 and has the same non-zero inclination angle as the axis of the special-shaped sealing ring 200 .

[0054] For example, Figure 3A 、 Figure 3B 、 Figure 3C and Figure 3D As shown, the shape of the axial cross section of the special-shaped sealing ring 200 may include: a figure with one end being an arc shape and the rest being a rectangle, an inverted trapezoid and a trapezoid. It should be noted that the axial cross section refers to the cross section passing through the axis of the special-shaped sealing ring 200. Figure 3A 、 Figure 3B 、 Figure 3C and Figure 3D Only a part of the axial cross-section of the special-shaped sealing ring 200 is shown. Since the special-shaped sealing ring 200 is symmetrical about the axis, the other part of the axial cross-section of the special-shaped sealing ring 200 that is not shown is respectively Figure 3A 、 Figure 3B 、 Figure 3C and Figure 3D The graphics in are the same, and the two parts of the graphics are symmetrical about the axis of the special-shaped sealing ring 200.

[0055] in, Figure 3A The special-shaped sealing ring 200 has an inner ring side surface 222 and an outer ring side surface 223 connecting the arc surface 211 and the plane 221, and is parallel to the axis of the special-shaped sealing ring 200 and perpendicular to the plane 221. The special-shaped sealing ring 200 with this cross section is conducive to the outer ring side surface 223 better bearing against the inner wall of the lens barrel 223. Figure 3BThe special-shaped sealing ring 200 has an inner ring side surface 222 and an outer ring side surface 223 connecting the arc surface 211 and the plane 221, and has a non-zero inclination angle with the axis of the special-shaped sealing ring 200, and the radial length of the plane 221 is less than the chord length of the arc surface 211, that is, the inner ring side surface 222 and the outer ring side surface 223 are inclined inward from the arc surface 221 to the plane 221. The inner ring side surface 222 and the outer ring side surface 223 of the special-shaped sealing ring 200 with this cross-section have a guiding function, which can facilitate the assembly of the special-shaped sealing ring 200.

[0056] Figure 3C The special-shaped sealing ring 200 has an inner ring side surface 222 and an outer ring side surface 223 connecting the arc surface 211 and the plane 221, and has a non-zero inclination angle with the axis of the special-shaped sealing ring 200, and the radial length of the plane 221 is greater than the chord length of the arc surface 211, that is, the inner ring side surface 222 and the outer ring side surface 223 are inclined outward from the arc surface 221 to the plane 221. The contact surface of the plane 221 of the special-shaped sealing ring 200 with this cross-section and the adjacent installed component 240 for press-fit is longer, which can make the fit with the component 240 more stable. Figure 3D The special-shaped sealing ring 200 has an inner ring side surface 222 connecting the arc surface 211 and the plane 221 and an axis of the special-shaped sealing ring 200 with a non-zero inclination angle, and an outer ring side surface 223 is parallel to the axis of the special-shaped sealing ring 200 and perpendicular to the plane 221. The inner ring side surface 222 of the special-shaped sealing ring 200 of this cross-section has a guiding function, which can facilitate the assembly of the special-shaped sealing ring 200, and the outer ring side surface 223 can better bear against the inner wall of the lens barrel 223.

[0057] In other optional embodiments, the portion of the sealing ring body 210 not connected to the sealing ring tail portion 220 has an arcuate surface 211. The end of the sealing ring tail portion 220, which is press-fitted with the adjacent component 240, has an arcuate surface 224. The sealing ring tail portion 220 further has an inner ring side surface 222 and an outer ring side surface 223 connecting the arcuate surface 211 and the arcuate surface 224. The inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail portion 220 each have an inclination angle with the axis of the special-shaped sealing ring 200. The inner ring side surface 222 and the outer ring side surface 223 can have the same inclination angle with the axis of the special-shaped sealing ring 200, or different inclination angles.

[0058] It should be noted that the embodiments of the present application do not limit the form of the inner ring side surface 222 and the outer ring side surface 223. For example, when the angle of inclination between the inner ring side surface 222 and / or the outer ring side surface 223 and the axis of the profiled seal ring 200 is 0°, the inner ring side surface 222 and / or the outer ring side surface 223 are parallel to the axis of the profiled seal ring 200 and are cylindrical. For another example, when the angle of inclination between the inner ring side surface 222 and / or the outer ring side surface 223 and the axis of the profiled seal ring 200 is non-0°, the inner ring side surface 222 and / or the outer ring side surface 223 are inclined relative to the axis of the profiled seal ring 200 and are conical. The conical surface can be a rotational surface that connects the arc surface 211 and the arc surface 224 (i.e., the outer edges of the two arc surfaces) and has the same non-zero inclination angle with the axis of the profiled seal ring 200.

[0059] For example, Figure 4A 、 Figure 4B and Figure 4C As shown, the shape of the axial cross section of the special-shaped sealing ring 200 may include: a figure with arc shapes at both ends and a middle part that is a rectangle, an inverted trapezoid and a trapezoid. Figure 4A 、 Figure 4B and Figure 4C Only a part of the axial cross-section of the special-shaped sealing ring 200 is shown. Since the special-shaped sealing ring 200 is symmetrical about the axis, the other part of the axial cross-section of the special-shaped sealing ring 200 that is not shown is respectively Figure 4A 、 Figure 4B and Figure 4C The graphics in are the same, and the two parts of the graphics are symmetrical about the axis of the special-shaped sealing ring 200.

[0060] in, Figure 4A The special-shaped sealing ring 200 has an inner ring side surface 222 and an outer ring side surface 223 connecting the arc surface 211 and the arc surface 224, and is parallel to the axis of the special-shaped sealing ring 200. The special-shaped sealing ring 200 with this cross section is conducive to better support of the outer ring side surface 223 against the inner wall of the lens barrel 223. Figure 4B The special-shaped sealing ring 200 has an inner ring side surface 222 and an outer ring side surface 223 connecting the arc surface 211 and the arc surface 224 and an axis of the special-shaped sealing ring 200 with a non-zero inclination angle, and the chord length of the arc surface 224 is smaller than the chord length of the arc surface 211, that is, the inner ring side surface 222 and the outer ring side surface 223 are inclined inward from the arc surface 221 to the arc surface 224. The inner ring side surface 222 and the outer ring side surface 223 of the special-shaped sealing ring 200 with this cross-section have a guiding function, which can facilitate the assembly of the special-shaped sealing ring 200.

[0061] Figure 4CThe special-shaped sealing ring 200 has a non-zero inclination angle between the inner ring side surface 222 and the outer ring side surface 223 connecting the arc surface 211 and the arc surface 224 and the axis of the special-shaped sealing ring 200, and the chord length of the arc surface 224 is greater than the chord length of the arc surface 211, that is, the inner ring side surface 222 and the outer ring side surface 223 are inclined outward from the arc surface 221 to the arc surface 224. The contact surface of the arc surface 224 of the special-shaped sealing ring 200 with this cross section and the adjacent installed component 240 is longer, which can make the fit with the component 240 more stable. Figure 3D Similarly, in the special-shaped sealing ring 200, the inner ring side surface 222 connecting the arc surface 211 and the arc surface 224 can have a non-zero inclination angle with the axis of the special-shaped sealing ring 200, and the outer ring side surface 223 can be parallel to the axis of the special-shaped sealing ring 200. The inner ring side surface 222 of the special-shaped sealing ring 200 of this cross-section has a guiding function, which can facilitate the assembly of the special-shaped sealing ring 200, and the outer ring side surface 223 can better bear against the inner wall of the lens barrel 223.

[0062] Compared with conventional sealing rings, the special-shaped sealing ring 200 provided in the embodiment of the present application can achieve waterproofing in multiple directions. Among them, the end of the sealing ring tail 220 that is pressed and matched with the adjacent installed component 240 can be a flat surface 221 or a circular arc surface 224 with a curvature, which can be determined according to the subsequent matching component 240. The circular arc surface 224, such as Figure 4A 、 Figure 4B and Figure 4C As shown, it has a plane 221 in the axial direction, as shown in FIG. Figure 3A 、 Figure 3B 、 Figure 3C and Figure 3D As shown, greater mobility can make assembly more flexible. The structure with symmetry at both ends, such as Figure 3A and Figure 4A As shown, the force will be more uniform, which can reduce the impact of deformation and distortion.

[0063] In situations where the size of the step forming the lateral pressure waterproof area on the lens G1 is difficult to control, which may result in an irregular shape of the lateral pressure waterproof area, embodiments of the present application can control the inclination angles of the inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail portion 220 of the shaped sealing ring 200, allowing the shaped sealing ring 200 to adapt to the outer circumferential surface of the step of the lens G1 of different shapes and to restrict the shaped sealing ring 200 between the lens G1 and the adjacent mounted component 240. By adapting the shaped sealing ring 200 to the different shapes of the lens G1, flexible adaptation is achieved, eliminating the need for high-precision control of the size and shape of the shaped sealing ring 200, reducing the difficulty and cost of manufacturing the shaped sealing ring 200, and achieving the limiting function of the shaped sealing ring 200 with low processing capacity and cost.

[0064] Alternatively, as Figure 5 As shown, the range of the inclination angle α of the inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail 220 of the special-shaped sealing ring 200 can be 0°≤α≤75°. That is to say, the inclination angle α of the inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail 220 can be either there or not. The reference line 260 can be a tangent line at the maximum outer circle of the arc surface 211 of the sealing ring body 210, and the reference line 260 is parallel to the axis of the special-shaped sealing ring 200. The inner ring side surface 222 and the outer ring side surface 223 can be tilted inward from the reference line 260, that is, in the direction close to the axis of the special-shaped sealing ring 200, and α is defined as a positive value when tilted. At this time, the cross-sectional figure of the sealing ring tail 220 gradually decreases from the connection with the sealing ring body 210, that is, the special-shaped sealing ring 200 has a relatively small tail, as shown in FIG. Figure 3B and Figure 4B Correspondingly, the inner ring side surface 222 and the outer ring side surface 223 can be tilted outward from the reference line 260, that is, in the direction away from the axis of the special-shaped sealing ring 200, and the value α is defined as a negative value. In this case, the cross-sectional shape of the sealing ring tail 220 gradually increases from the connection with the sealing ring body 210, that is, the special-shaped sealing ring 200 has a relatively large tail, as shown in FIG. Figure 3C and Figure 4C As shown. Because sealing rings are generally soft, there is a certain testing tolerance during testing, for example, a testing tolerance of ±1° to 2°. By controlling the range of the inclination angle α of the inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail 220, the embodiments of the present application can prevent the special-shaped sealing ring 200 from being subjected to excessive extrusion force and causing tensile deformation, thereby affecting the waterproof performance of the special-shaped sealing ring 200.

[0065] In some optional embodiments of the present application, such as Figure 5As shown, the radial length L of the portion where the seal ring tail 220 presses against the adjacent component 240 can be within a range of L ≥ 0.08 mm. When the portion where the seal ring tail 220 presses against the adjacent component 240 is a flat surface 221, the radial length of flat surface 221 is L. When the portion where the seal ring tail 220 presses against the adjacent component 240 is a circular arc surface 224, the chord length of the circular arc surface 224 is the radial length L. When the portion where the seal ring tail 220 presses against the adjacent component 240 is a wavy surface, the equivalent distance between the inner ring side surface 222 and the outer ring side surface 223 of the wavy surface is the radial length L. The embodiments of the present application control the radial length L of the portion where the sealing ring tail 220 is pressed against the adjacently installed component 240, thereby forming a contact surface between the sealing ring tail 220 and the adjacently installed component 240. This facilitates forming a compressed contact surface between the sealing ring tail 220 and the adjacently installed component 240, effectively limiting the position of the special-shaped sealing ring 200 and providing a basis for ensuring the waterproof performance of the special-shaped sealing ring 200. Optionally, the range of L can be 0.1mm≤L≤2mm. By controlling the range of L to 0.1mm≤L≤2mm, it is beneficial to achieve position limiting of the special-shaped sealing ring 200 on the basis of miniaturization of the special-shaped sealing ring 200.

[0066] In some optional embodiments of the present application, such as Figure 6 As shown, the axial distance d between the portion of the seal ring tail 220 that is press-fitted with the adjacent component 240 and the adjacent component 240 can be within a range of d≤0.05mm. When the portion of the seal ring tail 220 that is press-fitted with the adjacent component 240 is a flat surface 221, the axial distance between the flat surface 221 and the component 240 is d. When the portion of the seal ring tail 220 that is press-fitted with the adjacent component 240 is an arc surface 224, the distance between the chordal surface corresponding to the arc surface 224 and the component 240 is axial distance d. When the portion of the seal ring tail 220 that is press-fitted with the adjacent component 240 is a wavy surface, the distance between the equivalent plane of the wavy surface between the inner ring side surface 222 and the outer ring side surface 223 and the component 240 is axial distance d. The embodiment of the present application controls the axial distance d between the press-fit portion of the sealing ring tail 220 and the adjacent installed element 240 and the adjacent installed element 240, which is beneficial to the press-fit between the sealing ring tail 220 and the adjacent installed element 240, can effectively prevent the special-shaped sealing ring 200 from slipping and affecting the waterproof performance, and is also beneficial to the assembly of subsequent elements. If the axial distance d between the press-fit portion of the sealing ring tail 220 and the adjacent installed element 240 and the adjacent installed element 240 exceeds this control range, it may cause the special-shaped sealing ring 200 to slip and the subsequent elements to be assembled improperly, affecting the airtight effect of the special-shaped sealing ring 200.

[0067] In some optional embodiments of the present application, the compression rate W of the sealing ring head 210 may be in the range of W≥3%. The compression rate W of the sealing ring is mainly determined by measuring the diameter of the sealing ring and the depth of the sealing groove, such as Figure 7 As shown, the compression amount is equal to the diameter D of the sealing ring minus the depth H of the sealing groove. The compression rate W is calculated by dividing the compression amount by the diameter D of the sealing ring and is usually expressed as a percentage. The embodiments of the present application can maintain the compression rate W of the special-shaped sealing ring 200 at ≥ 3% by controlling the axial distance d between the press-fit portion of the sealing ring tail 220 and the adjacent installed component 240 and the adjacent installed component 240 to ≤ 0.05mm, thereby achieving effective waterproofing and sealing.

[0068] In some optional embodiments of the present application, the filling rate δ of the special-shaped sealing ring 200 can be in the range of 40% ≤ δ ≤ 98%. The filling rate δ of the sealing ring can be the ratio of the cross-sectional area of ​​the sealing ring's wire diameter to the area of ​​the groove formed between adjacent elements, that is, the area of ​​the sealing ring's accommodating space. The embodiments of the present application can ensure that the special-shaped sealing ring 200 is limited between the lens G1 and the lens barrel 230 by controlling the filling rate of the special-shaped sealing ring 200. Optionally, the range of δ can be 60% ≤ δ ≤ 95%. By controlling the range of δ to 60% ≤ δ ≤ 95%, the sealing performance of the special-shaped sealing ring 200 can be further improved, while facilitating the assembly of the special-shaped sealing ring 200 and preventing the special-shaped sealing ring 200 from deformation or damage.

[0069] The special-shaped sealing ring 200 provided in the embodiment of the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0070] In one embodiment of the present application, the special-shaped sealing ring 200 of the present application is applied to a waterproof lens. Figures 8A to 8CAs shown, the waterproof lens may include a lens barrel 230 and a lens G1, a special-shaped sealing ring 200, a light shielding sheet SOMA, and an optical lens G2, which are installed in sequence along the optical axis from the object side to the image side in the lens barrel 230. A stepped side pressure waterproof area is formed on the side S2 of the outer edge of the lens G1, and the special-shaped sealing ring 200 is located in the side pressure waterproof area of ​​the lens G1. The special-shaped sealing ring 200 includes a sealing ring body 210 and a sealing ring tail 220 connected to the sealing ring body 210. The sealing ring body 210 is interference-fitted with the outer circumferential surface of the step on the outer edge of the lens G1 and the lens barrel 230. The sealing ring body 210 is squeezed by the outer circumferential surface of the step on the outer edge of the lens G1 and the lens barrel 230, forming a sealing ring compression area to meet the waterproof requirement. The tail portion 220 of the sealing ring is pressed into fit with the light shielding piece SOMA. The tail portion 220 of the sealing ring can be against the light shielding piece SOMA to limit the position of the special-shaped sealing ring 200 in the side pressure waterproof area, so that the special-shaped sealing ring 200 will not slide to the rounded corner of the step of the lens G1 on the side S2 when it is squeezed by the external structure or impacted by the front airflow or water flow during the waterproof test, thereby effectively ensuring the waterproof performance of the special-shaped sealing ring 200.

[0071] The lens barrel 230 can be made of a metal that complies with the Restriction of Hazardous Substances (ROSH) directive, such as C3604 brass or A6061 aluminum. The lens G1 and optical lens G2 can be made of glass, with the optical lens G2 being a spherical lens. The special-shaped sealing ring 200 can be made of rubber, such as EPDM (Ethylene Propylene Diene Monomer) rubber. The sealing ring body 210 is connected to one end of the sealing ring tail 220, and the other end of the sealing ring tail 220 is tightly fitted with the light shielding piece SOMA. The portion of the sealing ring body 210 not connected to the sealing ring tail 220 has a circular arc surface 211, and the end of the sealing ring tail 220 that is tightly fitted with the light shielding piece SOMA is a flat surface 221. The inner ring side surface 222 and the outer ring side surface 223 of the sealing ring tail 220 connecting the circular arc surface 211 and the flat surface 221 have a non-zero inclination angle with the axis of the special-shaped sealing ring 200. Figure 8C As shown, the axial cross-section of the special-shaped sealing ring 200 comprises a shape consisting of an arc at one end and an isosceles inverted trapezoidal shape for the remainder. The inclination angle α of the inner and outer side surfaces 222 and 223 of the sealing ring tail 220 is 10.46°. The radial length L of the flat surface 221 of the sealing ring tail 220 is 0.4 mm. The axial distance d between the flat surface 221 and the light shielding sheet SOMA is either 0 mm or 0.03 mm.

[0072] The waterproof lens of this embodiment can be assembled using a flip-chip process. Figure 8C As shown, during the lens assembly process, the lens G1 is assembled first and installed into the interior of the lens barrel 230 from the rear end of the lens barrel 230. Then, the special-shaped sealing ring 200 is assembled. During the assembly process of the special-shaped sealing ring 200, a special jig is used to install the special-shaped sealing ring 200 into the interior of the lens barrel 230 from the rear end of the lens barrel 230. The special-shaped sealing ring 200 is confined in the steps formed by the large and small ends on the outer edge of the lens G1, that is, the side pressure waterproof area, and the special-shaped sealing ring 200 is made to lean inward as much as possible, that is, close to the large end of the lens G1, to prevent the special-shaped sealing ring 200 from tilting during the subsequent component assembly process. Then assemble the sunshade SOMA and the optical lens G2, and install the sunshade SOMA and the optical lens G2 into the interior of the lens barrel 230 from the rear end of the lens barrel 230 in turn, so that the sealing ring body 210 of the assembled special-shaped sealing ring 200 has an interference fit with the lens barrel 230 and the step of the lens G1, and the special-shaped sealing ring 200 has a clearance fit with the large end of the lens G1. Since the side space of the lens G1 is small, that is, the side pressure waterproof area, the special-shaped sealing ring 200 will be assembled to a position closer to the sunshade SOMA, and the sealing ring tail 220 of the special-shaped sealing ring 200 is pressed tightly against the sunshade SOMA.

[0073] In another embodiment of the present application, the special-shaped sealing ring 200 of the present application is applied to a waterproof lens.

The sealing ring body 210 is squeezed by the outer circumferential surface of the step on the outer edge of the lens G1 and the lens barrel 230, forming a sealing ring compression area to meet the waterproof requirement. The tail portion 220 of the sealing ring is pressed against the light shielding piece SOMA, and the tail portion 220 of the sealing ring rests on the light shielding piece SOMA, limiting the position of the special-shaped sealing ring 200 in the side pressure waterproof area, so that the special-shaped sealing ring 200 will not slide to the rounded corner of the step of the lens G1 on the side S2 when it is squeezed by the external structure or impacted by the front airflow or water flow during the waterproof test, thereby effectively ensuring the waterproof performance of the special-shaped sealing ring 200.

The inner ring side 222 and the outer ring side 223 of the sealing ring tail 220 connecting the arc surface 211 and the plane 221 are parallel, and are parallel to the axis of the special-shaped sealing ring 200 and perpendicular to the plane 221. As Figure 9C As shown, the axial cross-section of the special-shaped sealing ring 200 comprises a shape consisting of an arc-shaped end and a rectangular portion. The inclination angle α of the inner and outer side surfaces 222 and 223 of the sealing ring tail 220 is 0°. The radial length L of the flat surface 221 of the sealing ring tail 220 is 0.55 mm. The axial distance d between the flat surface 221 and the light shielding sheet SOMA is 0 mm. The special-shaped sealing ring 200 of this embodiment allows the edge of the sealing ring to better fit the inner wall of the lens barrel 230.
