DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] The utility model provides two technical solutions:

[0024] Figures 1-5The first embodiment is shown: a holographic three-dimensional display device with self-cleaning structure, comprising a box 1, the box 1 is internally provided with a holographic glass 31, the surface of the box 1 is provided with a mounting groove 12, the box 1 is internally provided with a lifting assembly 2, and the mounting groove 12 is internally provided with a cleaning assembly 4; the cleaning assembly 4 comprises an outer shell 41 mounted on the inner wall of the mounting groove 12, an inner shell 42 slidably arranged in the outer shell 41, a plurality of springs 43 fixedly connected between the inner wall of the outer shell 41 and the inner wall of the inner shell 42, the springs 43 generating a pushing force on the inner shell 42, a recess 44 formed in the side surface of the inner shell 42 facing the inside of the box 1, and a brush roller 45 rotatably arranged in the recess 44 and in contact with the surface of the holographic glass 31, and two rubber rollers 46 fixedly sleeved with the brush roller 45 at a position close to the middle of the outer wall of the brush roller 45 and in contact with the surface of the holographic glass 31.

[0025] Specifically, the inner shell 42 is close to the holographic glass 31 under the action of the springs 43, so that the brush roller 45 and the rubber roller 46 are always in contact with the surface of the holographic glass 31, and due to the friction between the rubber roller 46 and the holographic glass 31, the rubber roller 46 rolls during the lifting of the holographic glass 31, thereby driving the brush roller 45 to roll, and the brush roller 45 removes dust and other stains on the surface of the holographic glass 31 through friction with the surface of the holographic glass 31.

[0026] In this embodiment, the inside of the box 1 is in a hollow structure, and the box 1 is fixedly provided with a protective plate 11 on the top.

[0027] Specifically, the hollow structure in the box 1 provides the necessary space for the installation and movement of the holographic glass 31, the lifting assembly 2 and the cleaning assembly 4 and the like.

[0028] In this embodiment, the lifting assembly 2 comprises a sliding rail 21 fixedly installed on the inner bottom of the box 1 and a motor 22, the output end of the motor 22 is fixedly provided with a bidirectional screw rod 23, the outer surface of the bidirectional screw rod 23 is symmetrically threadedly sleeved with a sliding block 24, the sliding block 24 is slidably arranged in the sliding rail 21, and the outer surface of the bidirectional screw rod 23 is rotatably provided with an axle rod seat 28 at a position close to the distal end, and the axle rod seat 28 is fixedly installed on the inner bottom of the box 1.

[0029] Specifically, the sliding rail 21 provides a precise sliding track for the sliding block 24, ensuring that the sliding block 24 can move linearly stably when the motor 22 drives the bidirectional screw rod 23 to rotate, and the axle rod seat 28 provides a stable rotating support point for the distal end of the bidirectional screw rod 23, ensuring that the bidirectional screw rod 23 does not shake or deviate during rotation.

[0030] In the embodiment, the support seat 25 is fixedly connected to the top of each slider 24, and the connecting rod 26 is symmetrically arranged on each support seat 25. The plurality of connecting rods 26 are divided into two groups, each group having two connecting rods 26, and the top seat 27 is rotatably arranged between the connecting rods 26 of each group.

[0031] Specifically, the support seat 25 at the top of the slider 24 serves as the installation base of the connecting rod 26, and the power of the motor 22 and the bidirectional screw rod 23 is transmitted to the connecting rod 26. The movement of the slider 24 drives the support seat 25 to move synchronously, thereby causing the angle of the connecting rod 26 to change. The symmetric rotation of the connecting rod 26 enables it to convert the horizontal linear motion of the support seat 25 into the vertical lifting motion of the top seat 27.

[0032] In the embodiment, the base 3 is fixedly installed between the tops of the two top seats 27, and the top of the base 3 is connected to the bottom of the holographic glass 31.

[0033] Specifically, the base 3 at the top of the top seat 27 serves as the direct installation platform of the holographic glass 31, and the lifting force generated by the lifting assembly 2 is uniformly transmitted to the holographic glass 31.

[0034] Figures 1-5 The second embodiment is shown, and the main difference from the first embodiment is that the four installation grooves 12 are arranged in one group in front and back and in one group in left and right, and the two groups of installation grooves 12 are arranged in up and down staggered manner, so that the corresponding cleaning assemblies 4 are arranged in up and down staggered manner.

[0035] Specifically, the grouping and staggered arrangement of the installation grooves 12 enable the cleaning assemblies 4 to clean the holographic glass 31 without mutual interference.

[0036] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0037] In operation, when the holographic glass 31 needs to be cleaned, the motor 22 is started, the output end of the motor 22 drives the bidirectional screw rod 23 to rotate, the two sliders 24 and the support seat 25 move, the angle of the connecting rod 26 changes accordingly, the height of the top seat 27 changes, the base 3 and the holographic glass 31 are lifted, and the inner housing 42 moves towards the holographic glass 31 under the action of the spring 43, so that the brush roller 45 and the rubber roller 46 are always in contact with the surface of the holographic glass 31. When the holographic glass 31 is lifted, the rubber roller 46 rolls due to the friction force generated by the holographic glass 31, thereby driving the brush roller 45 to roll, and the brush roller 45 removes dust and other stains on the surface of the holographic glass 31 through friction with the surface of the holographic glass 31.

[0038] The four installation grooves 12 are arranged in up-and-down staggered manner, so that the corresponding cleaning assemblies 4 are also arranged in up-and-down staggered manner, so as to comprehensively cover each area of the holographic glass 31 and avoid cleaning dead angles, and ensure that the entire surface of the holographic glass 31 can be fully cleaned.

[0039] When the holographic glass 31 is lowered to the lower limit position, the inner housing 42 in the cleaning assembly 4 is gathered to the center, so that a relatively closed space is formed below the inner housing 42, so as to protect the holographic glass 31.
