[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See also Figure 2-Figure 10 , which is a modular panoramic lens 100 provided by the present invention. The modular panoramic lens 100 provided by the present invention has a compact internal installation structure and rationally utilizes the internal space, so that the volume of the entire panoramic lens 100 is reduced, making it more lightweight and compact.

[0033] Furthermore, if Figure 2 and Figure 3 The figure shows a schematic diagram of the three-dimensional structure and a front view of a modular panoramic lens 100 provided by the present invention. The modular panoramic lens 100 includes a middle frame assembly 10, two lens modules 20 symmetrically arranged along the center of the middle frame assembly 10, and a connector assembly 30 located inside the middle frame assembly 10 and electrically connected to the two lens modules 20. Figure 3As shown, the modular panoramic lens 100 provided by the present invention has a modular design of its internal structure, and has two relatively independently designed lens modules 20. The structures of the two relatively independently designed lens modules 20 provided in the modular panoramic lens 100 provided by the present invention are completely consistent, and the two relatively independent lens modules 20 are centrally symmetrically arranged inside the middle frame assembly, so that the gap between the two lens modules 20 in the middle frame assembly 10 is reduced, thereby making full use of the internal space in the middle frame assembly 10. The two lens modules 20 provided by the present invention are symmetrically distributed along the center of the middle frame assembly 10 in the middle frame assembly 10, compared with Figure 1 The conventional panoramic lens 100' reduces the installation space within the middle frame assembly 10, fully utilizing the internal space within the middle frame assembly 10 for arranging the two lens modules 20. Furthermore, the primary heat sources of the two lens modules 20 are located on either side of the middle frame assembly 10. This provides a compact installation structure while also separating the two heat sources, improving the heat dissipation of the entire panoramic lens 100.

[0034] Specifically, if Figure 7 As shown, the lens module 20 in the modular panoramic lens 100 provided by the present invention includes a fisheye lens 21 and a front cover assembly 22 for fixing the fisheye lens 21. The fisheye lens 21 has an optical component and a sensor component. The fisheye lens 21 is provided with a vertical circuit board 211 electrically connected to the connector assembly 30. The vertical circuit board 211 is a circuit board for receiving and transmitting data from the sensor component. The data captured by the optical component and the sensor component on the fisheye lens 21 can be transmitted to the camera through the connector assembly 30 for data analysis and processing. The fisheye lens 21 in the modular lens module 20 is fixed to the front cover assembly 22, so that the fisheye lens 21 and the front cover assembly 22 form a complete module. The front cover assembly 22 is then fixed to the middle frame assembly 10 to achieve a fixed connection between the fisheye lens 21 and the middle frame assembly 10.

[0035] Specifically, if Figure 4 As shown, in the modular panoramic module 100 provided by the present invention, the vertical circuit boards 211 of the two fisheye lenses 21 in the two lens modules 20 are symmetrically arranged on both sides of the middle frame assembly 10. In the lens module 20 provided by the present invention, the vertical circuit boards 211 in the fisheye lenses 21 are the main heating elements in the entire panoramic lens 100. The vertical circuit boards 211 are arranged on the sides of the entire lens module 20, so that the vertical circuit boards 211 can dissipate heat from both sides of the middle frame assembly 10. In addition, the two main heating elements are spaced apart in the middle frame assembly 10, making full use of the middle frame assembly 10 to dissipate heat, thereby improving the heat dissipation effect of the panoramic lens 100. Figure 7As shown, the vertical circuit board 211 of the fisheye lens 21 provided by the present invention is provided with a heat dissipation exposed copper area 2111 on the side surface close to the middle frame assembly 10. The large heat dissipation exposed copper area 2111 is provided on the vertical circuit board 211, so that the heat on the vertical circuit board 211 is exposed to the side surface of the middle frame assembly 10 through the heat dissipation exposed copper area 2111. As a result, the heat generated by the fisheye lens 21 will be diffused from the heat dissipation exposed copper area 2111 to the middle frame assembly 10.

[0036] Specifically, if Figure 8 As shown, it is a schematic diagram of the three-dimensional decomposition structure of the middle frame assembly 10 provided by the present invention. In the modular panoramic lens 100 provided by the present invention, the middle frame assembly 10 for accommodating and fixing two modular lens modules 20 includes a metal frame 11 fixedly connected to two front cover assemblies 22. The metal frame 11 is a rectangular frame structure, and each side is used to fix a lens module 20. The two lens modules 20 are inserted into the interior of the metal frame 11 from the front and back sides of the metal frame 11 and fixedly connected to the metal frame 11. Among them, an installation space 111 for accommodating two fisheye lenses 21 and a connector assembly 30 is formed in the metal frame 11. The metal frame 11 in the middle frame assembly 10 is fixedly connected to the front cover assembly 22 in the lens module 20, so that the fisheye lens 21 in the lens module 20 is symmetrically arranged in the installation space 111 enclosed by the metal frame 10, forming a structure as shown in FIG. Figure 4 The internal structure shown.

[0037] Furthermore, if Figure 8 As shown, the middle frame assembly 20 provided by the present invention also includes a heat insulating frame 12 that is snapped onto the outside of the metal frame 11. The heat insulating frame 12 is a U-shaped structure that is sleeved on the metal frame 11. The heat insulating frame 12 has two movable side edges that are arranged parallel to each other and a top edge connecting the two movable side edges. The overall thickness of the heat insulating frame 12 is relatively thin, which can ensure the heat dissipation effect of the metal frame 11 while also having a certain heat insulation effect, and the two movable side edges of the heat insulating frame 12 are arranged on the left and right sides of the metal frame 11. As shown Figure 4 As shown, the interior of the left and right sides of the metal frame 11 contact the main heat dissipation components of the lens module 20, thereby absorbing and transferring the heat generated by the lens module 20. To prevent the user from touching the sides of the metal frame 11 when using the modular panoramic lens 100, which could cause overheating and a poor user experience, the outer side of the metal frame 11, especially the left and right sides, is equipped with a heat insulation frame 12 to effectively prevent heat from the metal frame 11 from being transferred to the user's skin, thereby ensuring heat dissipation while also providing a heat-insulating effect.

[0038] Furthermore, if Figure 8As shown, in the middle frame assembly 10 provided by the present invention, the metal frame 11 is snap-connected to the outer heat insulation frame 12. Correspondingly, a slot 116 for the heat insulation frame 12 to be mounted is provided on the outer side surface of the metal frame 11, and a snap 121 that can be inserted into the slot 116 of the metal frame 11 is provided on the inner side surface of the heat insulation frame 12. The heat insulation frame 12 is snap-connected to the slot 116 via the snap 121. In addition, during the actual assembly process, double-sided tape is also provided at the connection between the outer side surface of the metal frame 11 and the heat insulation frame 12, thereby ensuring a stable connection between the metal frame 11 and the heat insulation frame 12 in the middle frame assembly 10.

[0039] Furthermore, if Figure 8 As shown, in the middle frame assembly 10 provided by the present invention, a heat dissipation protrusion 117 extending toward the side of the fisheye lens 21 is provided on the inner side surface of the metal frame 11. The heat dissipation protrusion 117 extends from the inner side wall of the metal frame 11 toward the center of the metal frame 11. The heat dissipation protrusion 117 of the metal frame 11 allows the metal frame 11 to be closer to the heat dissipation exposed copper area 2111 of the vertical mounting plate 211 of the fisheye lens 21 in the lens module 20. Figure 5 As shown, in the middle frame assembly 10 provided by the present invention, there is a certain gap between the heat dissipation protrusion 117 in the metal frame 11 and the heat dissipation exposed copper area 2111 of the vertical mounting plate 211, and thermal grease is applied to the gap, which is conducive to the heat generated by the fisheye lens 21 being transferred to the metal frame 11, forming a more efficient heat dissipation effect.

[0040] Furthermore, if Figure 7 As shown, in the modular panoramic lens 100 provided by the present invention, the connector assembly 30 located inside the middle frame assembly 10 includes a horizontal circuit board 31 disposed in the metal frame 11 and a connector 32 fixed on the horizontal circuit board 31 and extending from the bottom of the metal frame 11. The horizontal circuit board 31 is electrically connected to the vertical circuit board 211 of the lens module 20 through a flexible circuit board 33. Figure 7 As shown, the flexible circuit board 33 is a bent FPC. This flexible circuit board 33 fully utilizes the space at the bottom of the middle frame assembly 10. On the one hand, it uses the space at the bottom of the metal frame 11 to store the horizontal circuit board 31 in the connector assembly 30, allowing the connector 32 on the horizontal circuit board 31 to extend from the bottom of the metal frame 11, facilitating the assembly of the modular panoramic lens 100. On the other hand, the flexible circuit board 33 reduces the stress exerted by the connector assembly 30 on the fisheye lens 21, achieving electrical connection between the fisheye lens 21 and the connector assembly 30 within the rationally arranged internal space of the middle frame assembly 10.

[0041] Specifically, if Figure 8As shown, the bottom of the metal frame 11 in the middle frame assembly 10 provided by the present invention is provided with a strip hole 113 for allowing the connector 32 to extend. Fourth mounting holes 114 for fixing the connector 32 assembly 30 are provided on both sides of the strip hole 113. The connector 32 assembly 30 is fixed to the bottom of the metal frame 11 by a locking member. In the modular panoramic lens 100 provided by the present invention, two groups of lens modules 20 are provided in the metal frame 11, and the corresponding connector assembly 30 is provided with two connectors 32 for electrically connecting to the two groups of lens modules 20 respectively. Therefore, two strip holes 113 for allowing the connector 32 to extend are spaced apart at the bottom of the metal frame 11, and a pair of fourth mounting holes 114 are provided on both sides of each strip hole 113. The horizontal mounting plate 31 is fixed to the inside of the metal frame 10 from the outside of the metal frame 11 by a locking member.

[0042] Specifically, if Figure 5 As shown, the bottom of the metal frame 11 in the middle frame assembly 10 provided by the present invention is provided with two avoidance holes 115 on both sides of the strip hole 113. The two avoidance holes 115 are provided at the bottom of the metal frame 11, on both sides of the two strip holes 113. Figure 5 As shown, the avoidance hole 115 has a stepped structure, that is, there is a first rectangular through hole from the bottom surface of the metal frame 11 toward the center of the metal frame 11, and a second rectangular through hole is provided on the basis of the first rectangular through hole toward the center of the metal frame 11. The cross-sectional area of ​​the first rectangular through hole is larger than the cross-sectional area of ​​the second rectangular through hole. The avoidance hole 115 can not only reduce the overall weight of the entire metal frame 11, and serve the purpose of lightweight design for the modular panoramic lens 100, but also provide a reliable and stable fixing method for other panoramic lenses 100 and other components matched with it, so that the components matched with the panoramic lens 100 can be inserted into the two avoidance holes 115 at the bottom of the metal frame 11, which serves as a stable support between the metal frame 11.

[0043] Furthermore, if Figure 2 and Figure 3As shown, the front cover assembly 22 of the lens module 20 in the modular panoramic lens 100 provided by the present invention includes an upper shell 221 fixedly connected to the fisheye lens 21, a lens cover 223 covering the front side of the fisheye lens 21, and an outer cover 222 that secures the lens cover 223 to the upper shell 221. The upper shell 221 of the front cover assembly 22 is used to secure the fisheye lens 21 and to secure the fisheye lens 21 to the metal frame 11 of the middle frame assembly 10. The lens cover 223 of the front cover assembly 22 is disposed in front of the fisheye lens 21 and can be used to attach accessories such as protective lenses. The outer cover 222 is disposed between the upper shell 221 and the lens cover 223. This allows the lens cover 223 to be pressed against the front side of the upper shell 221 and also seals the outer surface of the upper shell 221, shielding all connectors on the upper shell 221 and creating an aesthetically pleasing effect. In this embodiment, the lens cover 223 is fixed to the outer cover 222 by glue, thereby achieving a relatively fixed connection between the lens cover 223 and the outer cover 222 .

[0044] Furthermore, if Figure 9 and Figure 10 The figure shows a schematic diagram of the three-dimensional structure of the upper shell 221 in the front cover assembly 22 provided by the present invention. The upper shell 221 in the front cover assembly 22 provided by the present invention plays the role of, on the one hand, fixing the fisheye lens 21, and on the other hand, fixing the connection with the metal frame 11. A center hole 2211 is provided on the upper shell 221 for the fisheye lens 21 to pass through. The fisheye lens 21 passes through the center hole 2211 of the upper shell 221, so that a 180° picture of the outside of the upper shell 221 can be captured. The upper shell 221 has a first mounting surface 2212 connected to the metal frame 11 and a second mounting surface 2213 connected to the outer cover 222. The first mounting surface 2212 and the second mounting surface 2213 are respectively located on the side surfaces of the center hole 2211. The fisheye lens 21 is fixed on the first mounting surface 2212 of the upper shell 221 , extends from the first mounting surface 2212 toward the second mounting surface 2213 , and extends out of the upper shell 221 from the central hole 2211 of the second mounting surface 2213 .

[0045] Specifically, if Figure 9 As shown, at least two first mounting holes 2212A for fixing the fisheye lens 21 are arranged on the first mounting surface 2212 of the upper shell 221 at intervals around the center hole 2211. In this embodiment, three first mounting holes 2212A for fixing the fisheye lens 21 are provided on the first mounting surface 2212 of the upper shell 221. The fisheye lens 21 is fixed to the three first mounting holes 2212A of the upper shell 221 through its own lens combination key. In addition, at least two mounting posts 2212B for positioning the fisheye lens 21 are also provided on the upper shell 221. In this embodiment, as shown in FIG. Figure 9As shown, a mounting post 2212B is provided on either side of the two first mounting holes 2212A at the bottom for positioning the fisheye lens 21. When installing the fisheye lens 21, the fisheye lens 21 is first inserted into the mounting post 2212B to secure the fisheye lens 21 to the upper shell 221. The first mounting surface 2212 of the upper shell 221 is then inserted into the first mounting hole 2212A using screws, rivets, or the like to secure the fisheye lens 21 to the upper shell 221.

[0046] Specifically, if Figure 10 As shown, the second mounting surface 2213 of the upper shell 221 is further provided with a second mounting hole 2213C connected to the metal frame 11. The upper shell 221 in the front cover assembly 20 of the present invention is fixedly connected to the metal frame 11 through the second mounting hole 2213C. Figure 8 As shown, the metal frame 11 has two lens mounting surfaces 112 that are relatively arranged for fixing the front cover assembly 22. A third mounting hole 1122 fixedly connected to the upper shell 221 is provided on the lens mounting surface 112 of the metal frame 11. In this embodiment, four second mounting holes 2213C are evenly distributed around the center hole 2211 on the second mounting surface 2213 of the upper shell 221. Correspondingly, four corresponding third mounting holes 1122 are also provided on the lens mounting surface 112 of the metal frame 11. The upper shell 221 is fixed to the metal frame 11 through a connecting piece. The connecting piece is fixed to the third mounting hole 1122 of the metal frame 11 by the second mounting surface 2213 of the upper shell 221 through the second mounting hole 2213C. The connecting piece can be a mounting component such as a screw, a screw, a rivet, a bolt, etc. that plays a connecting role. In this embodiment, as Figure 5 As shown, the connecting member is a stepped screw. The second mounting hole 2213C provided on the upper shell 211 is a stepped through hole. The second mounting hole 2213C is provided with a recessed platform structure for the connecting member. When the connecting member is inserted into the second mounting hole 2213C of the upper shell 211, the end face of the stepped bolt abuts against the recessed platform of the second mounting hole 2213C.

[0047] Furthermore, if Figure 5 As shown, in the modular panoramic lens 100 provided by the present invention, each second mounting hole 2213C provided on the upper shell 211 and fixedly connected to the metal frame 11 is provided with a first waterproof sealing ring 2216 that can be mounted on the connecting member. The first waterproof sealing ring 2216 is a silicone ring that is mounted on the connecting member used to fix the upper shell 211 to the metal frame 11 and is locked into the second mounting hole 2213C of the upper shell 211 through the connecting member, providing a waterproof seal at the connection between the upper shell 211 and the metal frame 11.

[0048] Furthermore, if Figure 9 As shown, a first annular protrusion 2212C is provided on the first mounting surface 2212 of the upper shell 221 in the front shell assembly 22 provided by the present invention, surrounding the edge of the upper shell 221. Figure 8 As shown, an annular groove 1121 for fixing the upper shell 221 is provided on the lens mounting surface 112 of the metal frame 11. Figure 6 As shown, the first annular protrusion 2212C is embedded in the annular groove 1121. In this embodiment, the metal frame 11 and the upper shell 221 are not only fastened together by the connector. A second waterproof sealing ring 118 fixedly connected to the upper shell 221 is also provided in the annular groove 1121 of the metal frame 11. The second waterproof sealing ring 118 is a waterproof double-sided tape. On the one hand, it plays the role of fixing the edges of the metal frame 11 and the upper shell 221. On the other hand, it plays a basic waterproof role, ensuring that water vapor on the outside of the metal frame 11 will not enter the interior of the metal frame 11 along the connection between the metal frame 11 and the upper shell 221, causing erosion of the lens module 20 inside the metal frame 11.

[0049] Furthermore, if Figure 9 and Figure 10 As shown, the upper shell 221 provided by the present invention further includes a second annular protrusion 2213A arranged around the center hole 2211 on the second mounting surface 2213. Figure 6 As shown, a third waterproof sealing ring 2214 is provided on the inner wall of the second annular protrusion 2213A, which is adapted to mate with the fisheye lens 21. This third waterproof sealing ring 2214 is disposed between the upper shell 221 and the fisheye lens 21. When the fisheye lens 21 is secured to the upper shell 221, this third waterproof sealing ring 2214 is pressed tightly against the second annular protrusion 2213A of the upper shell 221, providing a waterproof seal for the fisheye lens 21. The third waterproof sealing ring 2214, disposed between the upper shell 221 and the fisheye lens 21, is a silicone elastic soft rubber ring. When the fisheye lens 21 is secured to the upper shell 221, this silicone elastic soft rubber ring is squeezed by the fisheye lens 21 and tightly adheres to the space between the fisheye lens 21 and the upper shell 221, providing a waterproof seal.

[0050] Furthermore, if Figure 10 As shown, the second mounting surface 2213 of the upper shell 221 provided by the present invention is further provided with a third annular protrusion 2213B arranged around the edge of the upper shell 221. Figure 6As shown, the upper shell 221 is provided with a fourth waterproof seal ring 2215 between the second annular protrusion 2213A and the third annular protrusion 2213B, which is sealed with the outer cover 222. The fourth waterproof seal ring 2215 is provided on the second mounting surface 2213 of the upper shell 221, and is located on the upper shell 221 and the outer cover 222. In this embodiment, the fourth waterproof seal ring 2215 is a waterproof double-sided tape provided between the upper shell 221 and the outer cover 222. This waterproof double-sided tape not only securely connects the upper shell 221 and the outer cover 222, but also ensures a waterproof effect between the upper shell 221 and the outer cover 222, preventing external moisture and dust from entering the upper shell 221 through the connection between the upper shell 221 and the outer cover 222, thereby eroding the fisheye lens 21.

[0051] In the modular panoramic lens 100 provided by the present invention, four waterproof sealing designs are sequentially provided from the outside to the inside, which can meet the waterproof requirements of the entire panoramic lens 100. Among them, in the front shell component 22 of the panoramic lens 100, a fourth waterproof sealing ring 2215 is provided between the outer cover 222 and the upper shell 221, and a second waterproof sealing ring 118 is provided between the upper shell 221 and the metal frame 11. The fourth waterproof sealing ring 2215 and the second waterproof sealing ring 118 are both made of waterproof double-sided tape, which not only prevents water vapor from entering the gap, but also can simultaneously take into account the function of connecting the two components. At the same time, a first waterproof sealing ring 2216 is provided inside the second mounting hole 2213C where the upper shell 221 is fixedly connected to the metal frame 11, and a third waterproof sealing ring 2214 is provided between the upper shell 221 and the fisheye lens 21. The third waterproof sealing ring 2214 and the first waterproof sealing ring 2216 are both made of silicone elastic soft rubber. By locking the connector and fixing the fisheye lens 21, the sealing rings are compressed, thereby achieving a waterproof sealing effect at the setting location.

[0052] The two lens modules 20 in the modular panoramic lens 100 provided by the present invention are symmetrically arranged along the center, compactly installed and arranged, and fully utilize the internal space. The vertical circuit boards 211, which are the main heat dissipation components of the two lens modules 20, are distributed on both sides of the middle frame assembly 10, and a heat dissipation exposed copper area 2111 is provided on the vertical circuit board 211 to improve the heat dissipation effect of the fisheye lens 21. At the same time, a heat insulation frame 12 is provided on the outer side of the metal frame 11 to ensure heat dissipation while taking into account the heat insulation effect, thereby avoiding excessive touch temperature affecting the user experience; a multi-layer waterproof design scheme is designed in the entire panoramic lens to achieve a better waterproof effect.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
