Description

Technical Field

[0001] This utility model relates to the field of naked-eye 3D technology, and in particular to a combined lens. Background Technology

[0002] Conventional combined lens structure designs are arrays of single curved lenses. Optical adhesive layers and substrates are set on the bottom surface of the curved lens opposite to the refractive surface. This structure will converge the displayed image to a specific spatial position. Once the viewer deviates from the optimal viewing position, obvious image ghosting will be seen. In more severe cases, the left eye will see the content of the right eye, and the right eye will see the content of the left eye, causing the viewer to be unable to converge the correct image, resulting in easy eye fatigue.

[0003] In view of this, many designers have made various improvements to the existing technology, such as using lenses of different shapes to combine, which effectively avoids the above problems. However, this also brings shortcomings: the complex lens structure increases manufacturing costs and the maintenance difficulty of the combined lens. When a part of the combined lens is damaged, it is impossible to effectively repair the combined lens, inevitably causing a waste of resources. Therefore, a combined lens structure is proposed. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model aims to provide a combined lens, comprising a base plate, a lens block, and a lens head. By utilizing the sliding connection between the base plate and the lens block, as well as the sliding connection between the lens block and the lens head, the lens head can be easily replaced, thus facilitating the repair, maintenance, and replacement of this utility model.

[0005] To achieve the above objectives, this utility model provides a combined lens, including a base plate. The top surface of the base plate has multiple first horizontal sliding grooves, and multiple lens blocks are slidably connected in the first horizontal sliding grooves. The top of the lens blocks has a second horizontal sliding groove, and a lens head is slidably connected in the second horizontal sliding groove. The projections of the sliding direction of the lens blocks and the sliding direction of the lens head on the top surface of the base plate are perpendicular to each other.

[0006] Furthermore, the lens head includes a cylindrical lens, a spherical lens, and a prismatic lens; all three lenses can be slidably connected to the second horizontal groove.

[0007] Compared with the prior art, the present invention has at least the following beneficial effects: by setting lens heads of different shapes, and the sliding connection between the base plate and the lens block, and the sliding connection between the lens block and the lens head, the present invention can adapt the lens combination method according to actual usage needs to meet the usage needs of different scenarios; at the same time, when the lens head is worn or damaged and the lens combination cannot be used, the present invention can facilitate the replacement, maintenance and upkeep of the lens head, thereby improving the service life of the present invention.

[0011] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0012] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms “set up”, “connected”, and “linked” should be interpreted broadly.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0014] refer to Figures 1 to 2 This embodiment discloses a combined lens, including a base plate 10. The top surface of the base plate 10 has a plurality of first horizontal sliding grooves 11. A plurality of lens blocks 20 are slidably connected in the first horizontal sliding grooves 11. The top of the lens block 20 has a second horizontal sliding groove 21. The second horizontal sliding groove 21 is slidably connected in the second horizontal sliding groove 21. The projections of the sliding direction of the lens block 20 and the sliding direction of the lens head 300 on the top surface of the base plate 10 are perpendicular to each other.

[0015] Furthermore, the number of first horizontal slides 11 can be determined according to actual needs; one or more can be started. Lens blocks 20 within the same first horizontal slide 11 can be in direct contact. One or more lens heads 300 can be slidably connected within the same second horizontal slide 21. That is, the projected sizes of lens blocks 20 and lens heads 300 on the horizontal plane can be the same or different. If multiple first horizontal slides 11 are opened, the spacing between lens heads 300 within adjacent first horizontal slides 11 can be adjusted by sliding along the second horizontal slide 21.

[0016] According to actual usage needs, the operator can open a corresponding number of first horizontal slide grooves 11 on the top surface of the base plate 10, first install the lens head 300 into the second horizontal slide groove 21 on the top of the lens block 20, and then install the lens block 20 into the first horizontal slide groove 11. The lens head 300 is slid along the second horizontal slide groove 21 to adjust the position of the lens head 300 relative to the lens block 20, thereby facilitating the adjustment of the refraction angle of the light. When there are multiple first horizontal slide grooves 11, by adjusting the position of the lens head 300 relative to the lens block 20, the distance between the lens heads 300 in adjacent first horizontal slide grooves 11 can be adjusted, or the lens heads 300 in adjacent first horizontal slide grooves 11 can be made to directly contact each other so that the light can be refracted.

[0017] As a further embodiment of this invention: the lens head 300 includes a cylindrical lens 310, a spherical lens 320 and a prismatic lens 330; the cylindrical lens 310, the spherical lens 320 and the prismatic lens 330 can all be slidably connected to the second horizontal groove 21.

[0018] Furthermore, the prism lens 330 can be a triangular prism lens 330, a tetraangular prism lens 330, a pentagonal prism lens 330, etc.

[0019] By changing the shape of the lens head 300, the light refraction effect is further enhanced to meet the needs of different scenarios. By setting different shaped lens heads 300, and the sliding connection between the base plate 10 and the lens block 20, and the sliding connection between the lens block 20 and the lens head 300, this invention allows for adaptive adjustments to the lens assembly method according to actual usage requirements, thus meeting the needs of different scenarios. Simultaneously, when the lens head 300 becomes unusable due to wear or damage, this invention allows for convenient replacement of the lens head 300, thereby improving the service life of this invention.
