A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] The present invention provides an integrated lens module, which is arranged in a panoramic camera. Figure 1-Figure 3As shown, the integrated lens module includes a lens 1, an adapter ring 2 and a ball cover protective lens 3. Among them, the lens 1 includes a lens frame and a lens arranged in the lens frame, and the outer peripheral surface of one end of the lens frame is provided with a first external thread; the adapter ring 2 is provided with a central through hole 221 and a receiving cavity 211 which are interconnected and have coincident axes, and the inner peripheral surface of the central through hole 221 is provided with a first internal thread matching the first external thread, and the lens 1 is screwed into the central through hole 221 of the adapter ring 2 through the first external thread and the first internal thread; the inner peripheral surface of the receiving cavity 211 is provided with a second internal thread, and the outer peripheral surface of the ball cover protective lens 3 is provided with a second external thread matching the second internal thread, and the ball cover protective lens 3 is screwed into the receiving cavity 211 through the second external thread and the second internal thread.

[0034] The integrated lens module realizes direct connection of the ball cover protective lens 3 to the frame of the lens 1 through the adapter ring 2, effectively reducing the overall volume and weight of the panoramic camera; in addition, the central through hole 221 of the lens 1 and the adapter ring 2, as well as the ball cover protective lens 3 and the adapter ring 2 are all connected by threads, so that the coaxiality of the ball cover protective lens 3 and the lens 1 is high, which is beneficial to improving the assembly accuracy of the integrated lens module and making assembly more convenient.

[0035] Specifically, refer to Figure 1-Figure 2 The adapter ring 2 includes a ring body 21 and an extension 22. The extension 22 is arranged at one end of the ring body 21 facing the lens 1. The accommodating cavity 211 is arranged on the ring body 21, and the central through hole 221 is arranged on the extension 22. The outer peripheral surface of one end of the lens frame is provided with an annular support portion 11. When the lens frame is screwed into the central through hole 221, the extension 22 can abut against the annular support portion 11. This structure makes the structure of the integrated lens module more reasonable, and the abutment between the annular support portion 11 and the extension 22 can effectively prevent dust from entering the interior of the lens frame through the adapter ring 2.

[0036] Furthermore, in order to further improve the waterproof performance of the integrated lens module, the integrated lens module also includes a sealing ring 4, and a first annular groove 222 is provided at one end of the extension portion 22 facing the annular support portion 11, and the first annular groove 222 is communicated with the central through hole 221. The sealing ring 4 is arranged in the first annular groove 222, and the outer peripheral surface of the sealing ring 4 abuts against the groove wall of the first annular groove 222, the annular support portion 11 and the outer peripheral surface of the lens frame. The sealing ring 4 can effectively prevent liquid (such as water) from entering the interior of the lens frame through the gap between the extension portion 22 and the annular support portion 11.

[0037] In order to make the connection between the adapter ring 2 and the lens 1 more firmly, the ring body 21 is provided with a groove 212 connected to the central through hole 221 at the bottom of the accommodating cavity 211. The groove 212 is used for pouring glue. The glue can bond the ring body 21 and the frame of the lens 1 to improve the connection firmness.

[0038] Reference Figure 3 There are multiple grooves 212, and the multiple grooves 212 are evenly distributed around the axis direction of the adapter ring 2. Glue is poured into the multiple grooves 212, and the structural design is more reasonable.

[0039] Specifically, in order to ensure that the glue can be fully filled, the width dimension W of the groove 212 is in the range of 0.5 mm-1 mm, and the depth dimension D of the groove 212 is greater than 0.6 mm.

[0040] In order to ensure that the adapter ring 2 and the ball cover protective lens 3 are installed more firmly, the end surface of the ring body 21 of the adapter ring 2 facing away from the lens 1 is provided with a second annular groove 213 connected to the accommodating cavity 211, and glue can be poured into the second annular groove 213 to achieve bonding of the ring body 21 and the ball cover protective lens 3.

[0041] In order to ensure the parallelism between the ball cover protective lens 3 and the bottom of the accommodating cavity 211, the adapter ring 2 is provided with a recessed groove 214 at the bottom of the accommodating cavity 211, so that the bottom of the accommodating cavity 211 forms an annular raised portion 215. After the ball cover protective lens 3 is threadedly connected with the ring body 21, the ball cover protective lens 3 can abut against the annular raised portion 215. This structure can reduce the contact area between the ball cover protective lens 3 and the ring body 21 by providing the recessed groove 214, thereby improving the accuracy.

[0042] In order to ensure that the ball cover protective lens 3 has a certain impact resistance, the center thickness of the ball cover protective lens 3 is greater than 1.5 mm, which can effectively prevent the ball cover protective lens 3 from being broken by impact.

[0043] In order to prevent the ball cover protective lens 3 from being scratched, a coating is provided on the surface of the ball cover protective lens 3. The coating is an AF waterproof film, which has the characteristics of strong anti-fingerprint and anti-fouling capabilities and is easy to clean, and can also effectively prevent scratches.

[0044] Optionally, the adapter ring 2 may be a metal part, such as copper, stainless steel or aluminum; or, the adapter ring 2 may be a plastic part, such as PC plastic.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
