[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0019] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0020] An optical lens mounting base includes a lens body 1 and a flexible base 2 connected and mounted to the lens body 1. The flexible base 2 includes a flexible connecting post 21 and a flexible disk 22 connected to the flexible connecting post 21. The edge of the flexible disk 22 is provided with a flexible mounting ear 24. The flexible connecting post 21 includes a flexible inner connecting post 21b and a flexible outer connecting post 21a. The flexible inner connecting post 21b and the flexible outer connecting post 21a are fixedly connected by a first reinforcing rib 21d and form an integral whole. The flexible disk 22 is provided with an arc-shaped groove 23.

[0021] In this embodiment, the flexible base 2 is made entirely of spring steel. During installation, the lens body 1 is installed and fixed to the flexible base 2 by aligning the mounting hole at the center with the flexible connecting post 21. To ensure that the flexible connecting post 21 combines rigid stability with flexible buffering, it adopts a double-layer design, consisting of a flexible inner connecting post 21b and a flexible outer connecting post 21a. The flexible inner connecting post 21b and the flexible outer connecting post 21a are then connected and fixed into a whole by a first reinforcing rib 21d. This avoids the insufficient rigidity when using a single-layer flexible outer connecting post 21a, and also effectively avoids the problem of poor flexible buffering capacity caused by merging the flexible inner connecting post 21b and the flexible outer connecting post 21a into a solid whole.

[0022] In another preferred embodiment, a cavity 21c is formed between the flexible inner connecting post 21b, the flexible outer connecting post 21a, and the first reinforcing rib 21d. The cavity 21c is filled with a polymer material, such as rubber, to improve the overall buffering capacity of the flexible connecting post 21.

[0023] In a preferred embodiment, the diameter of the flexible connecting post 21 is variable, wherein the diameter of the end away from the flexible disk 22 is smaller than the diameter of the end closer to the flexible disk 22, which facilitates installation and docking.

[0024] In a preferred embodiment, to ensure the overall stability of the flexible base 2, a second reinforcing rib is provided at the connection between the flexible disk 22 and the flexible mounting ear 24. A third reinforcing rib is provided at the connection between the flexible connecting post 21 and the flexible disk 22, making the connection of the flexible base 2 more stable under stress. Simultaneously, to reduce the weight of the flexible disk 22 and improve its stability, a groove 25 is provided on the side of the flexible disk 22 away from the flexible connecting post 21. The groove 25 contains annular and rectangular reinforcing ribs, which are arranged alternately.

[0025] This invention, by incorporating flexible connecting columns, flexible discs, arc-shaped grooves, and reinforcing ribs, not only ensures the rigidity and stability of the mounting base but also provides good flexibility and buffering capabilities. This effectively avoids lens deformation caused by factors such as assembly stress, temperature stress, and environmental vibration.

[0026] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
