Description

Technical Field

[0001] This utility model relates to the field of lenses, and in particular to an ultra-thin optical lens structure. Background Technology

[0002] Ultra-thin optical lenses achieve structural compression primarily through precision optical design. The core of this technology lies in the use of special optical materials and innovative lens configurations. Such structures are widely used in devices with stringent size requirements, such as smartphones and endoscopes, and are a key technical solution for achieving both high pixel count and thinness.

[0003] Traditional lenses are easily damaged by impacts, requiring replacement and resulting in a relatively large waste of materials. Furthermore, the traditional ultra-thin optical lens structure has relatively poor impact resistance and a relatively short lifespan.

[0004] Therefore, those skilled in the art have provided an ultra-thin optical lens structure to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-thin optical lens structure. By setting a protective sleeve, the lens can be protected when it is bumped or knocked. Furthermore, the limiting post and the first spring, in conjunction with the limiting ring, can buffer the lens when it is bumped or knocked. This mechanism can effectively improve the lifespan of the lens, and the protective sleeve is detachable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An ultra-thin optical lens structure includes a main body, a fixing sleeve fixedly connected to the upper end of the outer wall of the main body, a limiting sleeve fixedly connected to the front end and rear end of the outer wall of the fixing sleeve, a button slidably connected to the inner wall of the limiting sleeve, a lower outer shell sleeved on the side of the outer wall of the main body near the upper end, a protective sleeve sleeved on the upper end of the outer wall of the main body, and a plurality of limiting posts fixedly connected to the upper surface of the lower outer shell, each of the limiting posts having a first spring sleeved on its outer wall; The lower outer shell has a second cavity at both the front and rear ends. A second spring is installed inside the second cavity, and a snap-fit ​​block is fixedly connected to the end of the second spring away from the main body. The above technical solution protects the lens from impacts by providing a protective cover. The limiting post and first spring, in conjunction with the limiting ring, cushion the lens during impacts, effectively extending the lens's lifespan. Furthermore, the protective cover is detachable from the main body, allowing for easy replacement when damaged. A button, latching block, and second spring enable quick cover replacement, significantly improving replacement efficiency and enhancing the device's practicality.

[0007] Furthermore, a first cavity is formed on the lower surface of the protective sleeve, and a limiting plate is fixedly connected to the upper surface of the lower outer shell near the middle. The above technical solution allows the protective sleeve to be positioned using the first cavity and the limiting plate, preventing it from shifting.

[0008] Furthermore, a limiting ring is fixedly connected to the upper end of the outer wall of the limiting post, and the limiting ring slides inside the first cavity; The above technical solution provides space for the movement of the limiting ring through the first cavity, and also limits the movement of the limiting ring.

[0009] Furthermore, the front and rear ends of the fixing sleeve are provided with second cavities, and the snap-fit ​​block slides inside the second cavity; The above technical solution provides space for the locking block to move through the second cavity and limits the locking block's position.

[0010] Furthermore, limiting grooves are provided at both the front and rear ends of the outer wall of the main body; The above technical solution allows the protective sleeve to be limited by the limiting groove.

[0011] Furthermore, a fixing plate is fixedly connected to the outer wall of the snap-fit ​​block; The above technical solution allows the locking block to be limited by the fixing plate.

[0012] Furthermore, a limiting shell is fixedly connected to the lower end of the outer wall of the protective sleeve; The above technical solution allows for limiting and protecting the device using a limiting shell.

[0013] This utility model has the following beneficial effects: 1. The present invention proposes an ultra-thin optical lens structure, which can protect the lens when it is bumped by setting a protective cover, and can buffer the lens when it is bumped by using a limiting post and a first spring in conjunction with a limiting ring. This mechanism can effectively improve the service life of the lens, and the protective cover is detachable.

[0014] 2. The ultra-thin optical lens structure proposed in this utility model has a detachable structure between the protective cover and the main body, which allows the protective cover to be replaced when it is damaged. Furthermore, the button, in conjunction with the snap-fit ​​block and the second spring, enables the protective cover to be replaced quickly. This mechanism can effectively improve the replacement efficiency of the protective cover and enhance the practicality of the equipment. Attached Figure Description

The button 4, in conjunction with the snap-fit ​​block 10 and the second spring 11, enables quick replacement of the protective sleeve 3, significantly improving replacement efficiency and enhancing the device's usability.

[0019] Reference Figure 1 , Figure 3 and Figure 5 The lower surface of the protective sleeve 3 has a first cavity 7. A limiting plate 14 is fixedly connected to the upper surface of the lower outer shell 17 near the middle. The first cavity 7 and the limiting plate 14 can limit the protective sleeve 3 and prevent it from shifting. A limiting ring 15 is fixedly connected to the upper end of the outer wall of the limiting post 6. The limiting ring 15 slides inside the first cavity 7. The first cavity 7 provides space for the limiting ring 15 to move and limits its movement. The front and rear ends of the fixed sleeve 2 have second cavities 9. The snap-fit ​​block 10 slides inside the second cavity 9, which provides space for the snap-fit ​​block 10 to move and limits its position. Limiting grooves 12 are provided at the front and rear ends of the outer wall of the main body 1. The limiting grooves 12 can limit the protective sleeve 3.

After entering, release the latching block 10. The latching block 10 pushes out the button 4. When a collision occurs, the upper end of the protective sleeve 3 will be impacted first. At this time, the upper end of the protective sleeve 3 squeezes the first spring 8. The first spring 8 contracts along the limiting post 6, and then the impact force is absorbed by the first spring 8.
