Problems solved by technology
[0006] Although the above prior art solves the problem that the holographic display device takes up a large volume and is not easy to carry through the folding mechanism, when the holographic display device is unfolded, it is necessary to manually unfold the frame of the device (including the base, the top cover and the connection between the base and the top cover). connector), and then manually unfold the holographic display panel; when folding the holographic display device, it is necessary to manually fold the holographic display panel first, and then manually fold the device frame
That is to say, the folding and unfolding of the existing holographic display device requires two-step manual operation, which makes the unfolding and folding operation more cumbersome and inconvenient to use

Embodiment Construction
[0027] figure 1 is a perspective view of a preferred embodiment of the holographic display device of the present invention in an unfolded state, figure 2 An exploded view of the structure of the holographic display device. Such as figure 1 and 2 As shown, the holographic display device includes a base 1, an upper cover 2, four holographic display panels 3 pivotally arranged on the side of the base 1 close to the upper cover 2, and four holographic display panels 3 connecting the base 1 and the upper cover 2. A collapsible support mechanism 4. Among them, the four holographic display panels 3 are all formed into an isosceles trapezoidal structure, and enclose a rectangular truss shape in the unfolded state; the four foldable support mechanisms 4 are respectively arranged between two adjacent holographic display panels 3 .
[0028] see figure 2 The foldable support mechanism 4 includes a sliding guide member 41 connected to the base 1 , a slider member 42 slidably connect...

The invention provides a foldable holographic display device. The foldable holographic display device comprises a base, an upper cover, a holographic display plate which is pivotally arranged on the side, close to the upper cover, of the base and multiple foldable supporting mechanisms connecting the base with the upper cover; the holographic display device further comprises an elastic reset component, and the holographic display plate can automatically pivot to be in an unfolding state under the action of the elastic reset component; a pressure contact part is arranged on the side, close to the base, of the upper cover, the pressure contact part applies acting force to the holographic display plate in the folding process of the foldable supporting mechanisms so as to make the holographic display plate pivot to be in the folding state. According to the holographic display device, one-step folding and unfolding can be achieved, and operation and use are convenient.
Description
technical field [0001] The invention relates to a foldable holographic display device. Background technique [0002] Aiming at the problems that the holographic display (projection) device takes up a large volume and is not easy to carry, various solutions for foldable holographic display devices are provided in the prior art. For example: [0003] Chinese patent document CN 203385995U discloses a portable holographic image box with folding and telescopic functions, including: a top cover, a display, four trapezoidal transparent plates (holographic display plates), a base with a rectangular groove on the upper surface and a folding The connecting wall; wherein, the display is embedded in the lower surface of the top cover, one of the sides of the top cover is fixed to the first fixed side of the connecting wall, and one of the sides of the base is fixed to the second fixed side of the connecting wall; in the open state, The waists of four trapezoidal transparent plates are...
