[0003] However, the lenses of panoramic camera modules are designed to be exposed, making them highly susceptible to scratches and impacts, which can easily lead to breakage and significantly reduce their lifespan. Furthermore, the protruding first element of the lens makes it even more vulnerable to impacts. As lenses are high-precision components, damage to them severely impacts performance and can even render them unusable. Moreover, lenses are generally expensive and have a complex structure, meaning users cannot repair or replace them themselves; professional repair is required. Therefore, lens damage incurs significant time and financial costs, severely impacting the user experience.

[0004] Therefore, it is necessary to provide a lens that allows users to more easily replace the first lens element. Utility Model Content

[0029] The lens 100 provided in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a lens 100, including a lens barrel 110. The lens barrel 110 has an object-side end, which refers to the end of the lens barrel 110 closer to the object being photographed, that is, the end of the lens barrel 110 facing the object being photographed. The lens 100 also includes a first lens 120, a fixing ring 130, other lenses, and a chip assembly. The first lens 120 is disposed at the object-side end of the lens barrel 110. The other lenses are disposed inside the lens barrel 110 and located between the first lens 120 and the chip assembly. Light passes sequentially through the first lens 120 and the other lenses to reach the chip assembly for imaging. The fixing ring 130 is connected to the lens barrel 110 and fixes the first lens 120 to the object-side end of the lens barrel 110, that is, the first lens 120 is fixed to the object-side end of the lens barrel 110 by the fixing ring 130. The fixing ring 130 is a ring structure with a through hole in the middle. The first lens 120 is a rotationally symmetrical structure. The fixing ring 130 contacts the periphery of the first lens 120 and fixes the first lens 120 on the lens barrel 110, ensuring that the fixing ring 130 will not affect the central light-transmitting area of ​​the first lens 120.

[0031] Specifically, such as Figure 3 and Figure 4As shown, a bearing surface 111 is provided on the object side end of the lens barrel 110, and the first lens 120 is placed on the bearing surface 111. The bearing surface 111 can be a single plane or composed of multiple parallel planes. That is, the bearing surface 111 can be flexibly adjusted according to whether the surface of the first lens 120 in contact with the lens barrel 110 is a plane or a stepped surface. The bearing surface 111 primarily serves to support and hold the first lens 120. A retaining ring 130 abuts against the periphery of the first lens 120 and is locked to the lens barrel 110 by a retaining screw 140. The retaining ring 130 is used to fix the first lens 120 to the bearing surface 111. It should be noted that the peripheral contact between the retaining ring 130 and the first lens 120 means that the retaining ring 130 is in close contact with the periphery of the first lens 120. This ensures that the retaining ring 130 can firmly lock the first lens 120 onto the bearing surface 111 of the lens barrel 110, while the retaining ring 130 does not affect the central light-transmitting area of ​​the first lens 120, thus ensuring the stable installation and normal light transmission of the first lens 120. Preferably, the retaining ring 130 is in contact with at least the surface of the first lens 120 furthest from the bearing surface 111, so that the retaining ring 130 can better press the first lens 120 onto the bearing surface 111 of the lens barrel 110, ensuring the installation stability of the first lens 120. The retaining ring 130 is secured to the lens barrel 110 by the fixing screw 140, allowing the retaining ring 130 and the first lens 120 to be detachably mounted on the lens barrel 110. This facilitates the user's ability to replace the damaged first lens 120 as needed. Furthermore, the fixing screw 140 ensures that the first lens 120 is firmly fixed to the bearing surface 111 of the lens barrel 110, preventing accidental contact with the retaining ring 130 that could affect the installation accuracy of the first lens 120 and ultimately reduce the image quality of the lens 100. In other words, the retaining ring 130, together with the fixing screw 140, ensures the installation stability of the first lens 120, enabling the lens 100 to be used in harsher environments.

[0032] In one embodiment, please refer to Figure 6The lens barrel 110 also includes a fixing surface 112 surrounding the outer side of the bearing surface 111. The fixing surface 112 has a first screw hole 1121, and the fixing ring 130 has a second screw hole 1321. A fixing screw 140 passes through the second screw hole 1321 and the first screw hole 1121 in sequence, locking the fixing ring 130 onto the lens barrel 110. Considering that the bearing surface 111 is the surface where the first lens 120 is installed, and that a high degree of surface flatness is required, a fixing surface 112 with the first screw hole 1121 is provided on the outer side of the bearing surface 111. This ensures that the lens barrel 110 can be easily locked onto the fixing ring 130 without affecting the installation accuracy of the first lens 120 on the bearing surface 111. Of course, by providing the second screw hole 1321 on the fixing ring 130 in conjunction with the first screw hole 1121 on the fixing surface 112, the fixing screw 140 can more easily lock the fixing ring 130 onto the lens barrel 110.

[0033] In one embodiment, there are multiple fixing screws 140, first screw holes 1121, and second screw holes 1321, all of which correspond one-to-one and are evenly distributed around the first lens 120. By providing multiple evenly distributed fixing screws 140, the compressive force exerted on the first lens 120 by the fixing ring 130 is made more uniform, preventing the first lens 120 from tilting when placed on the bearing surface 111. The number of fixing screws 140, first screw holes 1121, and second screw holes 1321 can be four, six, eight, or ten.

[0034] In one embodiment, such as Figure 4As shown, the lens barrel 110 also includes a limiting protrusion 113, which is located between the bearing surface 111 and the fixing surface 112, and protrudes from both the bearing surface 111 and the fixing surface 112. The limiting protrusion 113 and the bearing surface 111 form a lens limiting groove 114, and the limiting protrusion 113 and the fixing surface 112 form a fixing ring limiting groove 115. The limiting protrusion 113 is provided at the connection between the bearing surface 111 and the fixing surface 112 to divide the bearing surface 111 and the fixing surface 112 and form the lens limiting groove 114 and the fixing ring limiting groove 115. The first lens 120 is located within the lens limiting groove 114 and abuts against the limiting protrusion 113, preventing the first lens 120 from moving freely on the bearing surface 111 and ensuring the installation accuracy of the first lens 120. Similarly, the fixing ring 130 is located within the fixing ring limiting groove 115 and abuts against the limiting protrusion 113, preventing the fixing ring 130 from moving freely on the fixing surface 112 during installation and ensuring that the fixing ring 130 can be properly aligned with the lens barrel 110, facilitating the locking of the fixing screw 140. The design of the lens limiting groove 114 and the fixing ring limiting groove 115 makes the installation of the first lens 120 and the fixing ring 130 more convenient, providing a foolproof installation function and meeting the needs of automated production. The limiting protrusion 113 can be a single ring structure or formed by multiple protrusions.

[0035] In one embodiment, such as Figure 5 and Figure 6 As shown, the fixing ring 130 includes an abutment portion 131 and a fixing portion 132 surrounding the abutment portion 131. The abutment portion 131 abuts against the periphery of the first lens 120. The fixing portion 132 is provided with a second screw hole 1321, and the fixing portion 132 is fixed to the fixing surface 112 through the second screw hole 1321 and the fixing screw 140. Preferably, the abutment portion 131 and the fixing portion 132 form a stepped structure, that is, there is a height difference between the abutment portion 131 and the fixing portion 132 in the optical axis direction of the first lens 120, so that the fixing ring 130 can be better aligned and abut against the periphery of the first lens 120, that is, the fixing ring 130 can be better fitted onto the periphery of the first lens 120. Further preferably, the abutment portion 131 is further away from the first lens 120 relative to the fixing portion 132. This allows the first lens 120 to be positioned within the stepped structure enclosed by the abutment portion 131 and the fixing portion 132, ensuring that both the abutment portion 131 and the fixing portion 132 can contact the periphery of the first lens 120. This guarantees that the first lens 120 and the fixing ring 130 will not shift when locked to the lens barrel 110 by the fixing screw 140, improving the installation accuracy and efficiency of the first lens 120, the fixing ring 130, and the lens barrel 110. It should be noted that the optical axis direction of the first lens 120 refers to the direction in which light rays enter the first lens 120, that is, the direction parallel to the central rotation axis of the first lens 120.

[0036] It should be noted that the fixing ring 130 is a ring structure, wherein the abutting part 131 surrounds and forms a through hole, and the first lens 120 can at least partially pass through the through hole so that the first lens 120 can acquire light for imaging.

[0037] In one embodiment, a first positioning surface 1311 is provided on the side of the abutment portion 131 facing the first lens 120, and a second positioning surface 121 is provided on the periphery of the first lens 120. The first positioning surface 1311 and the second positioning surface 121 are parallel, and the first positioning surface 1311 and the second positioning surface 121 abut and limit each other. The parallel first positioning surface 1311 and the second positioning surface 121 ensure stable abutment between the fixing ring 130 and the first lens 120, ensuring the installation stability of the first lens 120 and preventing the first lens 120 from being squeezed and tilted by the fixing ring 130.

[0038] In one embodiment, please refer to the reference Figure 1 , Figure 2 and Figure 3 The lens 100 also includes a protective cover 150, which is detachably connected to the fixing part 132 and covers the first lens 120, i.e., the protective cover 150 covers the outer surface of the first lens 120 to prevent the surface of the first lens 120 from being scratched or bumped. It should be noted that the protective cover 150 is fixed to the fixing part 132 by screws, by a snap-fit ​​structure, or by adhesive that can be dissolved by heating to a specific temperature. This ensures that the protective cover 150 is detachably connected to the fixing part 132 of the fixing ring 130, so that the user can add a detachable protective cover 150 to protect the first lens 120 as needed.

[0039] In one embodiment, a first latching member 151 is provided around the periphery of the protective cover 150, and a second latching member 133 is provided on the fixing part 132. The first latching member 151 and the second latching member 133 engage with each other, using the first latching member 151 and the second latching member 133 to lock the fixing ring 130 and the protective cover 150, ensuring that both can be easily disassembled and improving the disassembly efficiency. Specifically, the first latching member 151 is a flat plate structure, and the second latching member 133 is a structure with a groove. The first latching member 151 is disposed in the second latching member 133, so that the first latching member 151 cannot move relative to the second latching member 133 in the optical axis direction of the first lens 120. That is, the second latching member 133 limits the first latching member 151, which means that the fixing part 132 of the fixing ring 130 limits the protective cover 150 in the optical axis direction, so that the protective cover 150 is disposed on the fixing ring 130.

[0040] Preferably, such as Figure 5As shown, the second fastener 133 includes an extension block 1331 and a limiting block 1332 connected at an angle. The extension block 1331 is disposed on the surface of the fixing part 132 facing the protective cover 150. The surfaces of the extension block 1331, the limiting block 1332 and the fixing part 132 together form a groove. The first fastener 151 can rotate between the limiting block 1332 and the fixing part 132, that is, the first fastener 151 can rotate into the groove, so that the first fastener 151 and the limiting block 1332 are engaged and fixed, thereby realizing the installation and fixation of the protective cover 150 and the fixing ring 130. Specifically, the extension block 1331 and the limiting block 1332 form an inverted L-shaped structure on the surface of the fixing part 132. The first fastening member 151 on the periphery of the protective cover 150 is disposed between the extension block 1331 and the limiting block 1332, so that the first fastening member 151 abuts against the limiting block 1332, thereby fixing the protective cover 150 onto the fixing ring 130. More preferably, the extension block 1331 extends from the surface of the fixing part 132 toward the protective cover 150 and is located at the edge of the fixing part 132. The limiting block 1332 is connected to the top of the extension block 1331 and extends toward the abutting part 131, so that the extension block 1331 and the limiting block 1332 form an inverted L-shaped structure, and the surfaces of the extension block 1331, the limiting block 1332 and the fixing part 132 together form a groove. The first fastener 151 is a flat plate structure. When the first fastener 151 is rotated between the limiting block 1332 and the fixing part 132, the first fastener 151 and the limiting block 1332 can be locked together and fixed, thus completing the installation and fixing of the protective cover 150.

[0041] In one embodiment, the protective cover 150 has a hemispherical structure and is made of plastic. The hemispherical structure of the protective cover 150 can better cover the first lens 120 while keeping the structural size of the protective cover 150 from being too large, thus ensuring that the lens 100 meets the miniaturization design requirements.

[0042] In one embodiment, such as Figure 3 and Figure 4 As shown, a sealing groove 116 is provided on the bearing surface 111, and a sealing element 160 is provided within the sealing groove 116. The sealing element 160 abuts against the bottom surface of the first lens 120 facing the bearing surface 111. That is, by providing a sealing groove 116 on the bearing surface 111 of the lens barrel 110, and a sealing element 160 within the sealing groove 116, moisture and dust are prevented from easily entering the sealed space between the first lens 120 and the lens barrel 110, thus achieving waterproofing and dustproofing. The sealing element 160 can be a structure made of elastic materials such as rubber or silicone, meaning the first lens 120 can compress the sealing element 160, ensuring a seal without affecting the installation accuracy of the first lens 120.

[0043] On the other hand, such as Figure 7 and Figure 8 As shown, this utility model also provides a panoramic camera module, including a housing 200, mounting screws 300, and two lenses 100 as described above. The housing 200 is a hollow cylindrical structure with openings at both ends, and each end surface of the housing 200 is provided with a third screw hole 210. A mounting plate 117 is provided around the periphery of the lens barrel 110, and a fourth screw hole 1171 is provided on the mounting plate 117. The two lenses 100 are arranged back-to-back inside the housing 200, and the mounting screws 300 pass through the fourth screw hole 1171 and the third screw hole 210 in sequence, fixing the two lenses 100 to the housing 200 by the mounting plate 117. By arranging the two lenses 100 back-to-back, the shooting field of view of the two lenses 100 forms a panoramic field of view, meeting the requirements for panoramic field of view shooting. It should be noted that the two lenses 100 are arranged back-to-back inside the housing 200, meaning that the two lenses 100 are oriented towards opposite ends and their optical axes are parallel, so that the two lenses 100 are arranged back-to-back and each takes a view in a forward or backward direction. Preferably, the mounting plate 117 is located outside the bearing surface 111, that is, the mounting plate 117 is located at the object side end of the lens barrel 110.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the scope of protection of this utility model.
