Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a honeycomb multi-hole array lens. Background Technology

[0002] A "honeycomb multi-aperture lens" is a special optical element that belongs to the category of diffractive optical elements or meta-optical elements. Its core feature is that it uses hexagonal (honeycomb-like) holes arranged at a subwavelength scale (usually smaller than the incident light wavelength) to manipulate light waves, thereby achieving lens-like functions (such as focusing and imaging).

[0003] Existing honeycomb paper porous lenses are commonly used in AR and VR devices as an important component of optical imaging systems. These lenses employ a honeycomb porous paper base structure, using a precise micropore array design to refract and focus light, achieving lightweight and low-cost imaging. However, because their overall thickness is typically compressed to millimeters or even sub-millimeter levels to fit the compact space requirements of head-mounted devices, this ultra-thin design, while effectively reducing device weight, also introduces significant mechanical strength defects. The honeycomb paper substrate itself is composed of interwoven fibers at the microscopic level, and its bending and impact resistance is far lower than that of traditional glass or resin lenses. In addition, the porous structure further weakens the continuity of the material, making the lens edges prone to cracking, delamination, or even breakage when subjected to slight external pressure or drops. Furthermore, changes in environmental humidity can cause the paper fibers to absorb moisture and expand, accelerating the deformation of the microporous structure and further reducing its durability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a honeycomb-shaped porous array lens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a honeycomb multi-hole array lens, comprising a lens module, the lens module being composed of a lens body and a lens sleeve, the lens sleeve being composed of two symmetrical semi-circular ring sleeves, one of the semi-circular ring sleeves having a locking groove on its side, a locking slider being slidably connected inside the locking groove, a locking spring being fixed between one side of the locking slider and the side wall of the locking groove, and a locking buckle being fixed on the side of the other semi-circular ring sleeve.

[0006] Preferably, the bottom of the lens sleeve has a slot, and both ends of the inner wall of the slot have limiting grooves. Both ends of the limiting grooves are slidably connected to limiting sliders. Limiting springs are fixed between the side of the limiting sliders on the same side that are far apart from each other and the side wall of the limiting groove. Limiting rollers are provided between the limiting sliders on opposite sides. The top of the lens sleeve has a plug. The plug is inserted into the slot at the bottom of another lens module. The plug squeezes the limiting rollers and the limiting springs. After the plug is fully inserted into the slot, the limiting springs provide a rebound force, so that the limiting rollers tightly bite the two sides of the plug to prevent the plug from coming off. When disassembling, only the plug needs to be pulled out, which will not affect the installation of the module and avoid scratches caused by friction between lenses during transportation.

[0007] Preferably, the top of the lens cover has a storage groove, and the bottom of the plug is rotatably connected to the inner wall of the storage groove. The storage groove stores the plug, and the hidden design prevents the plug from affecting the normal assembly of the lens module.

[0008] Preferably, the limiting roller and the limiting slider are fixedly connected, and the fixed connection improves the biting force between the limiting roller and the plug.

[0009] Preferably, the plug has engagement grooves on both sides and the top of the plug has arc surfaces on both sides. The engagement grooves improve the engagement between the plug and the limiting roller, and the arc surface design makes it easier for the plug to enter the slot.

[0010] Preferably, both ends of the latch on the side away from the latch spring are set as inclined planes, and one end of the latch is set as a hook angle.

[0011] Preferably, the side of the hook corner closest to the inclined plane and the inclined plane located at the hook corner are both provided with anti-slip textures. The anti-slip textures increase the interlocking force between the hook corner and the inclined plane, thereby improving the stability of the lock.

[0012] Beneficial effects

[0013] Existing honeycomb paper porous lenses are commonly used in AR and VR devices as an important component of optical imaging systems. These lenses employ a honeycomb porous paper base structure and achieve light refraction and focusing through a precise micro-pore array design, thereby achieving lightweight and low-cost imaging effects. However, because their overall thickness is usually compressed to the millimeter or even sub-millimeter level to meet the compact space requirements of head-mounted devices, this ultra-thin design, while effectively reducing the weight of the device, also brings significant mechanical strength defects. The honeycomb paper substrate itself is composed of interwoven fibers at the microscopic level, and its bending and impact resistance is far lower than that of traditional glass or resin lenses. In addition, the porous structure further weakens the continuity of the material, causing the lens edges to easily crack, delaminate, or even shatter when subjected to slight external pressure or drops. Furthermore, changes in environmental humidity can cause paper fibers to absorb moisture and expand, accelerating the deformation of the microporous structure and further reducing its durability. To address this issue, this invention employs a detachable protective sleeve to protect the lens, preventing cracks, delamination, or even breakage at the lens edge when subjected to slight external pressure or drops. During installation, the semi-circular protective sleeve is nested around the lens body, and the latch is inserted into the locking groove. Under the action of the inclined plane, the hook enters the locking groove and presses against the latch slider and latch spring. Once the latch is fully inserted into the locking groove, the hook engages with the inclined plane on the other side. Disassembly is quick and simple; simply pull out the latch. This design allows for easy and quick disassembly and assembly. The lens body is protected and can be replaced at any time, which is more convenient than a one-piece design. The hidden connection structure allows multiple lenses to be stacked, making it easy to transport and avoid scratches caused by friction between lenses. Rotate the plug in the storage slot and insert it into the slot at the bottom of another lens module. The plug presses against the limiting roller and the limiting spring. After the plug is fully inserted into the slot, the limiting spring provides a rebound force, making the limiting roller tightly bite the two sides of the plug to prevent the plug from coming off. When disassembling, simply pull out the plug and rotate it back into the storage slot. It will not affect the installation of the module and avoids scratches caused by friction between lenses during transportation. Attached Figure Description

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0028] Reference Figure 1-9 A honeycomb-shaped multi-hole array lens includes a lens module 1, which consists of a lens body and a lens sleeve 2. The lens sleeve 2 is composed of two symmetrical semi-circular ring sleeves. One of the semi-circular ring sleeves has a locking groove 201 on its side, and a locking slider 3 is slidably connected inside the locking groove 201. A locking spring 4 is fixed between one side of the locking slider 3 and the side wall of the locking groove 201. A locking buckle 5 is fixed to the side of the other semi-circular ring sleeve. Both ends of the side of the locking buckle 5 away from the locking spring 4 are set as inclined planes, and one end of the locking buckle 5 is set as a hook. Anti-slip textures are formed on the side of the hook near the inclined plane and on the inclined plane at the hook. The anti-slip textures increase the interlocking force between the hook and the inclined plane, improving the stability of the locking buckle 5.

[0029] The lens sleeve 2 has a slot 203 at its bottom. Both ends of the inner wall of the slot 203 have limiting grooves 204. Limiting sliders 8 are slidably connected to both ends of the limiting grooves 204. Limiting springs 9 are fixed between the opposite sides of the limiting sliders 8 and the sidewall of the limiting groove 204. Limiting rollers 7 are located between the limiting sliders 8 on opposite sides. A plug 6 is located at the top of the lens sleeve 2. The plug 6 is inserted into the slot 203 at the bottom of another lens module. The plug 6 presses against the limiting rollers 7 and the limiting springs 9. After the plug 6 is fully inserted into the slot 203, the limiting springs 9 provide a rebound force, causing the limiting rollers 7 to tightly engage both sides of the plug 6, preventing the plug 6 from detaching. Disassembly only requires pulling out the plug 6, without affecting the module installation and avoiding scratches caused by friction between lenses during transportation. The fixed connection between the limiting rollers 7 and the limiting sliders 8 increases the engagement force between the limiting rollers 7 and the plug 6. Both sides of the plug 6 are provided with engagement grooves 601, and both sides of the top of the plug 6 are designed as arc surfaces. The engagement grooves 601 improve the engagement between the plug 6 and the limiting roller 7, and the arc surface design makes it easier for the plug 6 to enter the slot 203.

[0030] The top of the lens cover 2 has a storage slot 202. The bottom of the plug 6 is rotatably connected to the inner wall of the storage slot 202. The storage slot 202 stores the plug 6. The hidden design prevents the plug 6 from affecting the normal assembly of the lens module.

[0031] The working principle of this utility model is as follows: A semi-circular ring sleeve is nested around the lens body. The latch 5 is inserted into the locking groove 201. Under the action of the inclined plane, the hook enters the locking groove 201 and squeezes the latch slider 3 and the latch spring 4. After the latch 5 is fully inserted into the locking groove 201, the hook engages with the inclined plane on the other side. When disassembling, simply pull out the latch 5. Disassembly and assembly are quick and simple. It protects the lens body and allows for easy replacement at any time. Compared with the one-piece design, it is more convenient and uses a hidden connection. The structure allows for the stacking of multiple lens groups, facilitating transportation and preventing scratches caused by friction between lenses. In the stacking type, by rotating the plug 6 inside the storage slot 202, the plug 6 is inserted into the slot 203 at the bottom of another lens module. The plug 6 presses against the limiting roller 7 and the limiting spring 9. After the plug 6 is fully inserted into the slot 203, the limiting spring 9 provides a rebound force, causing the limiting roller 7 to tightly grip both sides of the plug 6, preventing the plug 6 from coming off. When disassembling, simply pull out the plug 6 and then rotate it back into the storage slot 202.
