[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A camera module housing waterproof mechanism includes an upper shell 1 and a lower shell 2. A threaded slot 10 is provided at the inner middle position of the upper shell 1 through integral molding. The lower shell 2 is provided directly below the upper shell 1. A threaded inner cylinder 3 is fixedly connected to the top middle position of the lower shell 2, and a first rubber ring 4 is sleeved on the outside of the threaded inner cylinder 3. A second rubber ring 5 is sleeved on the outside below the first rubber ring 4, and a second rubber ring 5 is provided above the third rubber ring 6. Movable slots 13 are respectively provided at the lower left and lower right positions on the inner side of the upper shell 1, and one side of the movable slot 13 is connected to the first slot 7. A limiting snap ring 8 is provided on one side inside the first slot 7, and a rubber ring 9 is sleeved on the outside of the limiting snap ring 8. A second slot 16 is provided at the bottom position of the upper shell 1 through integral molding.

[0021] like Figure 1 、 Figure 2 and Figure 3As shown, the top of the upper shell 1 is fixedly connected with a conical collar 12, and the interior of the conical collar 12 is connected to each other through the interior of the upper shell 1 and the threaded groove 10. The inner end of the threaded groove 10 and the outer end of the threaded inner cylinder 3 are matched in size, and the top of the threaded inner cylinder 3 is fixedly connected with the camera body 11. When assembling the entire camera module shell structure, the upper and lower shells can be assembled together by screwing the threaded inner cylinder 3 and the threaded groove 10; the inner side of the first rubber ring 4 is provided with a rubber ring 9 The card slot is connected by a snap-fit ​​connection, and the first rubber ring 4, the second rubber ring 5 and the third rubber ring 6 are coaxially arranged. The second rubber ring 5 is a conical hollow structure, and the second rubber ring 5 is sleeved on the outside of the first rubber ring 4. The limiting snap ring 8 and the upper shell 1 are integrally formed. The outer end of the second rubber ring 5 and the inner end of the second card slot 16 are matched in shape. The rubber ring 9 is sleeved on the outside of the limiting snap ring 8, the first rubber ring 4 is inserted into the inside of the first card slot 7, and the second rubber ring is inserted into the inside of the second card slot 16. 5 and the third rubber ring 6 overlapping with the upper shell 1 will provide a sealed and waterproof protection for the entire shell structure after the upper and lower shells are assembled; a spring 14 is provided at one side position inside the movable groove 13, and one side end of the spring 14 is fixedly connected to a lock buckle 15, and one side end of the lock buckle 15 is provided on the outside of the first rubber ring 4. Before the upper shell 1 and the lower shell 2 are screwed together, the lock buckle 15 is in a state of being retracted inside the movable groove 13. When the upper shell 1 and the lower shell 2 are screwed together and the extrusion rod 17 is just inserted into the inside of the movable groove 13, the lock buckle 15 squeezed by the extrusion rod 17 will pop out and be engaged with the first rubber ring 4 after overcoming the rebound force generated by the spring 14. At this time, the rebound lock buckle 15 will lock and limit the first rubber ring 4 inserted into the first slot 7 to prevent the first rubber ring 4 from loosening and slipping out of the first slot 7 due to loosening of the thread between the upper and lower shells.

[0022] like Figure 2 、 Figure 3 and Figure 4 As shown, the four corner ends of the second rubber ring 5 are respectively connected with extrusion rods 17, and the extrusion rods 17 are fixedly connected to the lower shell 2. The four corner ends of the third rubber ring 6 are provided with slots for inserting the extrusion rods 17. The bottom of the upper shell 1 is provided with an annular groove for inserting the extrusion rods 17, and one end of the extrusion rods 17 is provided with a conical structure. After the first rubber ring 4 is sleeved on the outside of the threaded inner cylinder 3, the four extrusion rods 17 will play an auxiliary and limiting role in the installation of the second rubber ring 5 and the third rubber ring 6 when they are stacked and sleeved on the outside of the first rubber ring 4 in sequence.

[0023] Workflow: When assembling the entire camera module housing structure, the upper shell 1 can be first placed on the threaded inner cylinder 3 and the camera body 11 and the outside. Then, along the thread axis reserved inside the threaded groove 10, the camera body 11 is screwed onto the outside of the conical collar 12. This allows the upper shell 1 and the lower shell 2 to be combined under the sealing protection of the waterproof structure, facilitating the subsequent use of the camera module.

[0024] At the same time, in the process of assembling the entire camera module, when the outer shell assembly is waterproofed, the first rubber ring 4 can be first put on the outside of the threaded inner cylinder 3, and then the second rubber ring 5 and the third rubber ring 6 can be stacked and put on the outside of the first rubber ring 4 in sequence. When the upper shell 1 is fitly put on the outside of the threaded inner cylinder 3 and the camera body 11, and is screwed together with the lower shell 2 through the threaded inner cylinder 3 and the threaded groove 10, the rubber ring 9 limited by the internal support of the limiting clamping ring 8 will just be stuck into the inside of the first rubber ring 4, and the second groove 16 will also be engaged and connected with the second rubber ring 5 at the same time. At this time, the waterproof structure composed of the rubber ring 9 put on the outside of the limiting clamping ring 8, the first rubber ring 4 stuck in the inside of the first groove 7, the second rubber ring 5 stuck in the inside of the second groove 16, and the third rubber ring 6 overlapping with the upper shell 1 will achieve sealing protection from the connection between the upper and lower shells after the upper and lower shells are assembled.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
