Description

Technical Field

[0001] This utility model relates to the field of liquid lens technology, specifically to an adjustable focus lens based on liquid lenses. Background Technology

[0002] As is well known, in the field of optical imaging, traditional lens systems typically rely on a series of mechanical moving components to change the focal length or focus. This design not only increases the complexity of the lens system but also limits its response speed and accuracy. Especially for applications requiring rapid focal length adjustment, such as video recording, autofocus cameras, and camera modules in various smart devices, traditional lens structures are inadequate. With technological advancements, liquid lenses have begun to attract attention as a novel optical element. Liquid lenses are based on the electrowetting effect, adjusting the curvature of the liquid interface by changing the voltage applied to the liquid, thereby achieving focal length adjustment. Compared to traditional mechanical lenses, liquid lenses have the following advantages: liquid lenses do not require additional space for lens group movement, thus significantly reducing the overall size of the lens. Although liquid lens technology brings many innovative improvements, in practical applications, the compatibility and ease of installation between liquid lenses and traditional lens mounts need improvement. Especially in miniaturized and lightweight applications, ensuring accurate installation of liquid lenses remains a challenge. Because the working principle of liquid lenses depends on the state of the internal liquid, improper installation or insecure fixing may cause liquid displacement, affecting image quality. If a liquid lens malfunctions and needs replacement or repair, existing designs often lack a simple and quick way to disassemble and reassemble it. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an adjustable focusing lens based on liquid lens, which has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model relates to an adjustable focusing lens based on a liquid lens, comprising a lens mount 1 and a liquid lens module 2. One end of the lens mount 1 has a docking groove, and the liquid lens module 2 rests against the docking groove. One end of the lens mount 1 has a positioning groove. The liquid lens module 2 has a positioning box 3, which rests against the positioning groove. The positioning box 3 has an electrode connector 4, and the positioning groove has an interface 5. An annular inclined groove 6 is formed on the outer ring of the liquid lens module 2. The lens mount 1 has a fastening box 7. A threaded hole is formed between the top of the fastening box 7 and the docking groove. A fastening groove is formed between the inside of the fastening box 7 and the threaded hole. A threaded post 8 is provided on the threaded hole, and a cone 9 is provided at the bottom of the threaded post 8, which rests against the annular inclined groove 6. A locking mechanism is provided between the threaded post 8 and the fastening box 7. In this embodiment, the liquid lens module 2 is aligned and rests against the positioning groove via the positioning box 3, thereby... The liquid lens module 2 is placed against the docking groove on the lens mount 1. At this time, the liquid lens module 2 is inserted into the interface 5 through the electrode connector 4 of the positioning box 3, thereby connecting the liquid lens module 2 to the control circuit. At this time, the threaded post 8 in the threaded hole is aligned with the annular groove 6 on the outer ring of the liquid lens module 2. By releasing the locking mechanism, the threaded post 8 is rotated and moves in the threaded hole, so that the cone 9 at one end of the threaded post 8 contacts and abuts against the annular groove 6. Through the tilt angle of the annular groove 6, the liquid lens module 2 can be more firmly abutted against the docking groove, thereby quickly assembling and fixing the liquid lens module 2 onto the lens mount 1, realizing the rapid assembly of the liquid lens module 2. By using the curvature of the liquid interface of the liquid lens module 2, the focal length adaptive calibration is realized, which is a common liquid lens adjustment technology in the prior art. It will not be described in detail in this structure. This structure can realize the rapid assembly or disassembly of the liquid lens module 2 through the cooperation of the fastening box 7 and the annular toothed groove, which is convenient to use.

[0023] To facilitate locking the threaded post 8 and prevent it from loosening, in this design, the locking mechanism includes a toothed ring 10 and a fastening hole. The fastening hole is located at one end of the fastening box 7, and an L-shaped plate 11 is provided on the fastening hole. A toothed plate 12 is provided between one end of the L-shaped plate 11 and the fastening groove. An elastic member 13 is provided between the toothed plate 12 and one end of the fastening groove. The toothed ring 10 is mounted on the threaded post 8 and located in the fastening groove, and the toothed plate 12 engages with the toothed ring 10. By pulling the L-shaped plate 11, the elastic component 13 is compressed and deformed by the toothed plate 12, and the toothed plate 12 moves away from the toothed ring 10, which facilitates the rotation of the threaded column 8. The threaded column 8 drives the toothed ring 10 to rotate and move in the fastening groove. The space of the fastening groove is sufficient for the toothed ring 10 to rotate and move, which facilitates the adjustment of the position of the cone 9 in the annular inclined groove 6 and the threaded hole. By loosening the L-shaped plate 11, the elastic component 13 elastically supports the toothed plate 12, so that the toothed plate 12 engages and abuts against the toothed ring 10, thereby locking the threaded column 8.

[0024] To better position and assemble the liquid lens module 2, in this design, an auxiliary groove is provided at one end of the lens mount 1, and an auxiliary box 14 is provided on the liquid lens module 2. The auxiliary box 14 rests against the auxiliary groove. By moving the auxiliary box 14 of the liquid lens module 2 against the auxiliary groove, the liquid lens module 2 can be better positioned and assembled on the lens mount 1. Positioning holes are provided on both the auxiliary groove and the positioning groove, and positioning posts 15 are provided on both the positioning box 3 and the auxiliary box 14. The positioning posts 15 rest against the corresponding positioning holes, thereby further facilitating the positioning and assembly of the liquid lens module 2.

[0025] In order to improve the sealing between the liquid lens module 2 and the lens mount 1, in this solution, a sealing ring 16 is provided on the docking groove. The sealing ring 16 can improve the sealing of the contact surface between the liquid lens module 2 and the docking groove.

[0026] To further enhance the elastic support of the toothed plate 12, in this design, two elastic components 13 are provided and symmetrically arranged. The elastic components 13 are alloy springs. By using two symmetrically arranged elastic components 13 and alloy springs, the toothed plate 12 can be better elastically supported, thereby ensuring that the toothed plate 12 is stably engaged against the toothed ring 10.

[0027] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
