Technical Field

[0001] This utility model relates to the field of imaging technology, and in particular to a lens protection structure and imaging device. Background Technology

[0002] A fundus camera is an examination device that captures images of the fundus of the eye to determine if there are any lesions in the optic nerve, retina, choroid, and refractive media. The eyepiece lens of the fundus camera is crucial in its optical system. Dust, grease, or dirt on the eyepiece can cause reflections and rainbow-like spots in the captured images, directly affecting image quality and hindering professional interpretation. Therefore, fundus cameras typically have a protective cover on the lens to protect it from dirt. However, the current protective covers for fundus cameras are cumbersome to install and remove, resulting in a poor user experience. Utility Model Content

[0033] A fundus camera is an examination device that captures images of the fundus of the eye to determine if there are any lesions in the optic nerve, retina, choroid, and refractive media. The eyepiece lens of the fundus camera is crucial in its optical system. Dust, grease, or dirt on the eyepiece can cause reflections and rainbow-like spots in the captured images, directly affecting image quality and hindering professional interpretation. Therefore, fundus cameras typically have a protective cover on the lens to protect it from dirt. However, the current protective covers for fundus cameras are cumbersome to install and remove, resulting in a poor user experience.

[0034] Based on this, this utility model proposes a lens protection structure for imaging equipment, aiming to solve the problem of cumbersome disassembly and assembly of protective covers in existing fundus cameras. Among other things, Figures 1 to 4 A schematic diagram of the lens protection structure provided by this utility model.

[0035] Please see Figures 1 to 4 In one embodiment of the present invention, the lens protection structure 100 includes a housing 1, a protective cover 2, and a magnetic connection structure 3. The protective cover 2 covers the housing 1, and the magnetic connection structure 3 includes a first magnetic part 31 and a second magnetic part 32 respectively disposed on the housing 1 and the protective cover 2. The first magnetic part 31 and the second magnetic part 32 magnetically engage to make the protective cover 2 detachably installed on the housing 1.

[0036] In the technical solution of this utility model, when the imaging device is not needed, the protective cover 2 is brought close to the housing 1. At this time, the first magnetic suction part 31 and the second magnetic suction part 32 magnetically attract each other, so that the protective cover 2 can be fixed to the housing 1. When the imaging device needs to be used, the housing 1 and the protective cover 2 can be separated by applying force away from the housing 1. Thus, by setting the housing 1, the imaging module 200 and the protective cover 2 can be installed. By setting the protective cover 2, the imaging module 200 can be protected and prevented from being contaminated. At the same time, by setting the first magnetic suction part 31 and the second magnetic suction part 32, it is easy to fix the protective cover 2 to the housing 1 and easy for the user to remove the protective cover 2 directly, thereby solving the problem that the installation and removal of the protective cover 2 of the existing fundus camera is relatively cumbersome.

[0037] It should be noted that there are various types of magnetic attraction parts 31 and 32. For example, both the first magnetic attraction part 31 and the second magnetic attraction part 32 can be magnets, or the first magnetic attraction part 31 can be a magnet and the second magnetic attraction part 32 can be a magnet, etc. As long as they can be magnetically attracted and fixed, this utility model does not limit them.

[0038] In one embodiment of this utility model, please refer to Figure 3 Multiple first magnetic suction parts 31 are provided, and the multiple first magnetic suction parts 31 are arranged at intervals along the circumference of the housing 1. In this way, by providing multiple first magnetic suction parts 31, the protective cover 2 and the housing 1 are magnetically fixed at different positions, thereby helping to strengthen the connection between the housing 1 and the protective cover 2.

[0039] In another embodiment, please refer to Figure 2 Multiple second magnetic suction parts 32 are provided, and the multiple second magnetic suction parts 32 are arranged at intervals along the circumference of the protective cover 2. In this way, by providing multiple second magnetic suction parts 32, the protective cover 2 and the housing 1 are magnetically fixed at different positions, thereby helping to strengthen the connection between the housing 1 and the protective cover 2.

[0040] It should be noted that the above two related technical features, "a plurality of first magnetic suction parts 31 are provided, and the plurality of first magnetic suction parts 31 are arranged at intervals along the circumference of the housing 1" and "a plurality of second magnetic suction parts 32 are provided, and the plurality of second magnetic suction parts 32 are arranged at intervals along the circumference of the protective cover 2", can be provided selectively or simultaneously, and this utility model does not limit this.

[0041] In one embodiment of this utility model, please refer to Figure 3The first magnetic suction part 31 is circular, which reduces its size and prevents interference with other structures within the housing 1, facilitating its placement within the housing 1. Of course, in other embodiments, the first magnetic suction part 31 can also be rectangular or polygonal, etc., and this invention does not limit this. Furthermore, the first magnetic suction part 31 can be positioned in various ways; it can be located on the outside of the housing 1 or on the inside of the housing 1, etc., and this invention does not limit this. Specifically, the first magnetic suction part 31 is located on the inside of the housing 1 to hide it, thereby improving the appearance of the housing 1.

[0042] In another embodiment, please refer to Figure 2 The second magnetic suction part 32 is arranged in a strip shape. This strip shape increases the size of the second magnetic suction part 32, which helps to reduce the docking accuracy between the first magnetic suction part 31 and the second magnetic suction part 32, and facilitates docking with the first magnetic suction part 31. Of course, in its embodiment, the second magnetic suction part 32 can also be circular or rectangular, etc., and this utility model does not limit it in this way.

[0043] It should be noted that the two related technical features mentioned above, namely, "the first magnetic attraction part 31 is circular" and "the second magnetic attraction part 32 is strip-shaped", can be set either one or both, and this utility model does not limit this.

[0044] In one embodiment of this utility model, the protective cover 2 is made of a flexible material. This flexible material facilitates molding, allowing the protective cover 2 to fit tightly against the surface of the housing 1. This not only prevents contamination of the imaging module 200 but also disperses impacts when subjected to external shocks, reducing damage to internal components. Of course, in other embodiments, the protective cover 2 can also be made of polymer materials such as plastic.

[0045] In one embodiment of this utility model, the protective cover 2 and the second magnetic part 32 are integrally formed. This integral forming not only saves subsequent assembly processes, but also makes it easier to hide the second magnetic part 32 inside the protective cover 2, thereby helping to improve the appearance of the protective cover 2.

[0046] Furthermore, there are various ways to arrange the second magnetic part 32. The second magnetic part 32 can be arranged on the side of the protective cover 2 facing the housing 1, or it can be embedded inside the protective cover 2. This utility model does not limit this.

[0047] In one embodiment of this utility model, please refer to Figure 2 and Figure 4 The lens protection structure 100 also includes a positioning structure 4 disposed between the housing 1 and the protective cover 2 for positioning the position of the protective cover 2. Thus, by setting the positioning structure 4, the position of the protective cover 2 can be positioned on the housing 1, which not only helps to quickly install the protective cover 2 onto the housing 1, but also helps to align the first magnetic part 31 and the second magnetic part 32.

[0048] Furthermore, the positioning structure 4 includes a positioning protrusion 41 and a mating recess 42 respectively provided on the housing 1 and the protective cover 2. The positioning protrusion 41 and the mating recess 42 are positioned together. Thus, by providing the mutually mating positioning protrusion 41 and the mating recess 42, it is convenient to quickly install the protective cover 2 onto the housing 1.

[0049] In one embodiment of this utility model, please refer to Figure 2 The protective cover 2 includes a cover body 21 and an abutment portion 22 extending from the periphery of the cover body 21. The abutment portion 22 extends radially along the cover body 21 to abut against the housing 1. Thus, by providing the abutment portion 22 to abut against the housing 1, the position of the protective cover 2 in the axial direction of the housing 1 is positioned so that the protective cover 2 can fit snugly against the housing 1.

[0050] Furthermore, the second magnetic attraction part 32 is disposed on the abutting part 22. Since the abutting part 22 can abut against the housing 1 and the gap between them is minimal, the second magnetic attraction part 32 is disposed on the abutting part 22 so that the second magnetic attraction part 32 can be closer to the first magnetic attraction part 31, thereby helping to strengthen the connection of the magnetic attraction connection structure 3.

[0051] This utility model also proposes an imaging device, which includes a lens protection structure 100. The specific structure of the lens protection structure 100 is as described in the above embodiments. Since this imaging device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The imaging device includes a fundus camera.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
