Description

Technical Field

[0001] This utility model relates to the field of holographic waveguide storage technology, specifically a thin and light holographic waveguide fixing component. Background Technology

[0002] Grating waveguides (also known as holographic waveguides or diffractive waveguides) are a type of optical see-through near-eye display technology, primarily used in augmented reality (AR) applications. This technology eliminates the bulky optical structures of traditional near-eye display systems such as freeform surfaces, off-axis reflections, prisms, and arrayed waveguides. By using grating diffraction and waveguide principles to deflect, conduct, and expand light beams, it achieves near-eye image display with ultra-thin lenses (less than 2mm) and ultra-large screen sizes (greater than 40 degrees). This technology was first proposed in China by Beijing Xiaolong Technology Co., Ltd., and mass production has already been achieved. After processing, the grating waveguide sheets require storage boxes for preservation.

[0003] A storage box for storing grating sheets, as described in prior art (application number 201820655252.1), includes an inner box. The top surface of the inner box has a storage slot, and at least one reinforcing rib is provided within the storage slot. Each reinforcing rib extends along the width direction of the inner box to both sides. By providing at least one reinforcing rib within the storage slot and extending along the width direction of the inner box to both sides, the structural strength of the two sides along the long side of the storage box is improved, reducing the impact of external forces on the collimated grating sheets stored therein. This significantly improves the yield of the collimated grating sheets delivered to the customer. However, the stability of holographic waveguide sheets stored and fixed within the storage box is poor, and it is inconvenient to retrieve and place the holographic waveguide sheets. Utility Model Content

[0004] The purpose of this invention is to provide a thin and light holographic waveguide fixing component to solve the problems of poor stability and inconvenience in the storage and fixing of holographic waveguide sheets in the storage box in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thin and light holographic waveguide fixing assembly, including a storage box, an upper cover inserted into the upper side of the storage box via a plug, a plurality of partitions evenly spaced in the storage slot inside the storage box, and a holographic waveguide sheet positioning slot between adjacent partitions, a first slider elastically sliding in a first groove on one side of the partition via a first spring and a second spring, and a carrying plate between two first sliders via a support plate, a second slider in a second groove on both sides of the upper end of the carrying plate via a third spring, a positioning clamp on the upper side of the second slider, and a pull rod on the upper side of the support plate.

[0006] Furthermore, a first guide rod is provided in the first groove, and the first slider is slidably disposed with the first guide rod.

[0007] Furthermore, the first spring and the second spring are respectively sleeved on the outside of the first guide rods on both sides of the first slider.

[0008] Furthermore, the pull rod is arranged parallel to the partition, and the length of the pull rod is less than the height of the partition.

[0009] Furthermore, a limiting plate is rotatably provided at one end of the pull rod, and the outer support plate on the outer wall of the limiting plate can be rotated ninety degrees and locked onto the top of the partition.

[0010] Furthermore, the second slider and positioning clamp are provided in two sets symmetrically with respect to the carrier plate, and the inner wall of the positioning clamp is provided with a protective layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has multiple partitions evenly spaced in the storage slot of the storage box, and a holographic waveguide positioning slot is provided between adjacent partitions for longitudinal insertion and positioning of the holographic waveguide. In addition, a positioning clamp plate elastically sliding on the upper side of the carrier plate is used to clamp and fix the two sides of the holographic waveguide, which facilitates the improvement of the stability of the holographic waveguide inserted and fixed in the storage box.

[0013] 2. This utility model utilizes a first slider that is elastically slidable in a first groove on one side of a partition via a first spring and a second spring, and a carrier plate is provided between the two first sliders via a support plate. The lower end of the holographic waveguide sheet is placed on the carrier plate, and one end of the carrier plate is elastically slidable in the partition via the first slider and the spring, so that the holographic waveguide sheet stored on the carrier plate can be subjected to vertical shock absorption treatment, thereby improving the safety of storage and use.

[0014] 3.

A top cover 5 is inserted into the upper side of the storage box 1 via a plug 6. Multiple partitions 2 are evenly spaced in the storage compartment inside the storage box 1, and holographic waveguide sheet positioning grooves 3 are provided between adjacent partitions 2 for longitudinal insertion and positioning of holographic waveguide sheets 4. A first slider 8 is elastically slidably disposed within a first sliding groove 7 on one side of a partition 2 via a first spring 16 and a second spring 15. A first guide rod 19 is provided within the first sliding groove 7, and the first slider 8 is slidably disposed with the first guide rod 19. Furthermore, a carrier plate 10 is provided between the two first sliders 8 via a support plate 9. A second slider 11 is provided in the second sliding groove 17 on both sides of the upper end of the carrier plate 10 via a third spring 18. A positioning clamp 12 is provided on the upper side of the second slider 11, so that the positioning clamp 12 is elastically slidable on the upper side of the carrier plate 10. Two sets of second sliders 11 and positioning clamp 12 are symmetrically arranged about the carrier plate 10. The inner wall of the positioning clamp 12 is provided with a protective layer for clamping and fixing the two sides of the holographic waveguide sheet 4, which facilitates the improvement of the stability of the holographic waveguide sheet 4 inserted and fixed in the storage box 1.

The first spring 16 and the second spring 15 are both damping springs to prevent repeated bouncing, so that the holographic waveguide sheet 4 stored on the carrier plate 10 can be subjected to vertical shock absorption treatment, thereby improving the safety of storage and use.

[0025] like Figure 1 and Figure 3 As shown, in order to facilitate better handling of the holographic waveguide sheet 4, a limiting plate 14 is rotatably provided at one end of the pull rod 13, and the outer support plate 20 of the outer wall of the limiting plate 14 can be rotated 90 degrees and locked onto the top of the partition plate 2, so that pulling the pull rod 13 and the outer support plate 20 can be rotated 90 degrees and locked onto the top of the partition plate 2, which is used to position the upward-moving adjustment carrier plate 10, making it easier to handle the holographic waveguide sheet 4.

[0026] The working principle and usage process of this utility model are as follows: In use, multiple partitions 2 are provided at equal intervals in the storage slot of the storage box 1, and holographic waveguide plate positioning slots 3 are provided between adjacent partitions 2 for longitudinal insertion and positioning of holographic waveguide plates 4.
