[0023] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combination Figure 1 , Figure 2 The illustration shows a first specific embodiment of a portable module stand for media-free holographic display according to this utility model. It mainly includes a lower base plate 1, an upper mounting plate 2, and a support plate 3 connecting the lower base plate 1 and the upper mounting plate 2. The lower base plate 1 and the upper mounting plate 2 can be parallel to each other or at an angle. For example, the lower base plate 1 can be horizontal, and the upper mounting plate 2 can be at an angle of approximately 10° to the horizontal plane to accommodate different display needs. Similarly, the support plate 3 can be perpendicular to the horizontal plane or inclined. When the support plate 3 is inclined, the angle between the lower base plate 1 and the support plate 3 is 90°-120°, preferably 105°, 110°, or 115°. The lower base plate 1, upper mounting plate 2, and support plate 3 are integrally formed, resulting in a stable overall structure. Specifically, to enhance the stability of the stand, a combination of one or more of the following can be provided at the bottom of the lower base plate 1: a rubber pad, a magnetic sheet, or Velcro.

[0026] A limiting block 4 is provided on the inner side of the support plate 3. The length of the limiting block 4 is the same as the width of the support plate 3. The limiting block 4 and the support plate 3 cooperate to form a placement area for placing the electronic display element A. The electronic display element A can be an electronic screen or a mobile phone. Similarly, to enhance the stability of the electronic display element A, one or more combinations of rubber pads, magnetic sheets, and Velcro can be provided on the upper surface of the limiting block 4 and the inner side of the support plate 3. In particular, the limiting block 4 can also be set as two blocks, upper and lower, which can be connected by a spring. When the electronic display element A is not placed, the two limiting blocks 4 are in contact under the action of the spring. When the electronic display element A needs to be placed, the two limiting blocks 4 are separated, the spring is stretched by force, and then the electronic display element A is placed between the two limiting blocks 4. At this time, the two limiting blocks 4 clamp and fix the electronic display element A under the action of the spring. This is not limited here.

[0027] An optical waveguide 5 is mounted on the upper mounting plate 2 and is embedded within the upper mounting plate 2. The optical waveguide 5 is used to perform medium-free holographic imaging of the content displayed by the electronic display element A to form an aerial image a located above the upper mounting plate 2. In this embodiment, the optical waveguide 5 is selected from the microchannel matrix optical waveguide flat panel of Xianghang (Shanghai) Technology Co., Ltd. Since this is an existing component, the underlying principles will not be elaborated upon.

[0028] The module bracket structure of this embodiment is simple and easy to carry. When using it, simply place it on the placement platform and then place the electronic screen or mobile phone on the limiting block 4. The electronic screen or mobile phone emits image light, which is refracted by the optical waveguide plate to form a medium-free holographic image, making it convenient to use.

[0029] Example 2: In this example, the difference from Example 1 is that the support plate 3 is detachably connected to the lower base plate 1 and / or the upper mounting plate 2 for easy carrying. Specifically, for example, the support plate 3 can be detachably connected to both the lower base plate 1 and the upper mounting plate 2 simultaneously, or the support plate 3 can be detachably connected only to the lower base plate 1, or the support plate 3 can be detachably connected only to the upper mounting plate 2. The detachable connection can be achieved by snap-fit ​​or by fasteners. The fasteners can be screws, pluggable telescopic sleeves, or other detachable connection methods, as long as a detachable chain connection can be achieved, they all fall within the scope of this application.

[0030] Example 3: Combination Figure 3 , Figure 4 As shown, in this embodiment, the difference from Embodiment 1 is that the outer edge of the lower base plate 1 is provided with a locking groove 1a, and the length of the locking groove 1a extends along the width direction of the lower base plate 1. A locking member 6 is rotatably installed in the locking groove 1a. The locking member 6 is a long locking strip, and the two ends of the long locking strip are rotatably connected to the two ends of the locking groove 1a through a rotating shaft 7.

[0031] When using the module bracket, place it on the placement platform, then flip the clip 6 outward from the bottom plate 1 to secure it with the edge of the placement platform. Figure 3 As shown, this design ensures the stability of the module bracket and prevents it from tipping over. When not in use, the card 6 can be flipped and stored inside the module bracket. The card slot 1a limits the flipping angle of the card 6, as shown. Figure 4 As shown, this makes the module bracket easy to carry.

[0032] In this embodiment, the card 6 uses a long card strip, but it is not limited to this and can also use multiple short cards. Specifically, multiple card slots 1a are provided at intervals along the width direction on the outer edge of the lower base plate 1. A short card is rotatably installed in each card slot 1a. The longitudinal cross-sectional shape of the short card is the same as that of the long card strip, and the length of the short card is shorter than that of the long card strip. The short card is used in the same way as the aforementioned long card strip.

[0033] Example 4: Combination Figures 5 to 7As shown, in this embodiment, the difference from the first embodiment is that the outer side of the support plate 3 is provided with an upper groove 8 and a lower groove 9 that are connected vertically. The upper groove 8 is provided with a sliding plate 10 that can slide up and down. The sliding plate 10 is provided with a positioning groove 10a. A support bracket 11 is rotatably installed in the positioning groove 10a. The support bracket 11 can be rotatably accommodated in the lower groove 9.

[0034] When using the module bracket, place it on the placement platform, then flip the support bracket 11 outward from the support plate 3. The support bracket 11 can limit the flipping angle through the positioning groove 10a. Next, slide the slide plate 10 downward, causing the support bracket 11 to slide downward and contact the placement platform. The support bracket 11, support plate 3, and placement platform form a triangle. Figure 5 As shown, this design ensures the stability of the module support and prevents it from tipping over. When not in use, the support bracket 11 can be folded up and stored inside the module support, as shown. Figure 7 As shown, this makes the module bracket easy to carry.

[0035] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
