DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The cultural relic display device of the digital multimedia technology is realized based on the cultural relic display cabinets arranged in a straight line, and one or more OLED transparent screens 2 are used as public cultural relic multimedia display devices to serve the multimedia display of several cultural relics;

[0035] The equipment is divided into four parts, namely track 1, OLED transparent screen 2, mobile power supply component and speed limit protection component;

[0036] like Figure 1 , Figure 5 As shown, a straight track 1 is fixed on the top of the front of the cultural relic display cabinet, the internal cavity cross-section of the track 1 is rectangular, the front of the track 1 has a straight opening, and a conductive bar 12 is arranged on the symmetrical side of the straight opening. The conductive bar 12 is powered by the power distribution facilities of the exhibition hall, and racks 11 are symmetrically arranged at the upper and lower parts of the track 1;

[0037] like Figure 4 , Fig.10 As shown, the mobile power supply assembly is based on the seat plate 3, and two or more sets of gears 8 are arranged on the back of the seat plate 3. Each set of gears 8 has two gears distributed in an upper and lower manner. The gears 8 are placed inside the track 1 and are respectively engaged with the racks 11 connected to the upper and lower parts. The upper and lower distribution widths of the gears 8 are greater than the linear opening width of the track 1, so that the seat plate 3 can move stably and linearly along the track 1.

[0038] like Figure 4 , Figure 6 As shown, a convex shell 31 is fixed at the center of the seat plate 3, and two or more through slots 32 are formed through the convex shell 31. An electrode block 33 is elastically slidably arranged in the through slot 32 by a spring. The convex shell 31 is inserted into the track 1 from the straight opening portion, so that the electrode block 33 is aligned one by one with the conductive strip 12;

[0039] like Figure 2 , Figure 3 As shown, the OLED transparent screen 2 adopts the existing high-transparency OLED screen, the edge of the OLED transparent screen 2 is protected by a hard frame, the top of the OLED transparent screen 2 has a mounting frame shell, the mounting frame shell is equipped with a controller, a processor and a data storage module for storing multimedia information introducing each cultural relic, and the front of the mounting frame shell has a front camera and a speaker for shooting the user's use status and playing the display voice;

[0040] like Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, an electrode column 21 for supplying power to the OLED transparent screen 2 is arranged on the back of the frame shell installed on the top of the OLED transparent screen 2, and the frame shell installed on the top of the OLED transparent screen 2 is attached to the seat plate 3 and fixed with screws. During the attachment process, the electrode column 21 is inserted into the through slot 32 to contact the electrode block 33 to move, so that the electrode block 33 is squeezed and contacts the conductive strip 12, so as to realize the mobile power supply of the OLED transparent screen 2, and a rear camera 7 pointing to the cultural relics is arranged on the back of the frame shell installed on the OLED transparent screen 2, and the rear camera 7 is connected to the OLED transparent screen 2 through the controller and the processor, and a press switch 22 is installed on the back of the seat plate 3, and the press switch 22 is connected to the rear camera 7 through the controller, and a convex strip 13 is arranged on the surface of the track 1 at the position of each cultural relic booth, and the convex strip 13 is used to contact the press switch 22;

[0041] The OLED transparent screen 2 is transparent when not in operation, and does not affect visitors' viewing of the cultural relics in the display cabinet. When visitors need to learn more about the cultural relics, they can move the OLED transparent screen 2 to the display cabinet of the cultural relics, and the convex strip 13 will contact the pressing switch 22, so that the controller controls the rear camera 7 to take photos of the cultural relics. The processor compares the photo information and obtains the corresponding cultural relic multimedia information from the data storage module for playback and introduction.

[0042] like Fig.10 As shown, each group of two gears 8 distributed up and down are meshed with each other, so that the two gears 8 rotate synchronously and restrict each other, one of the gears 8 is connected to the damping assembly 5, the damping assembly 5 includes a packaging shell 51, the packaging shell 51 is fixedly connected to the base plate 3, the packaging shell 51 has a cylindrical cavity 52, the shaft end of the gear 8 is rotatably inserted into the cylindrical cavity 52, a plurality of blades 53 are annularly distributed around the shaft end of the gear 8, the blade 53 is slidably arranged on the inner wall of the cylindrical cavity 52, the cylindrical cavity 52 is filled with damping fluid, and the surface of the blade 53 has a gate 54 for conducting the damping fluid;

[0043] In the process of moving the OLED transparent screen 2, the gear 8 meshes and rolls along the rack 11, and the gear 8 drives the vane 53 to rotate. In the process of rotation of the vane 53, the damping fluid passes through the gate 54. The damping fluid generates a damping force on the rotation of the vane 53, so that the rotation of the gear 8 has a damping property, thereby preventing the OLED transparent screen 2 from moving too flexibly and being difficult to position.

[0044] like Figure 8 , Fig. 9 As shown, the speed limiting protection component adopts a speed limiting component 4, and the speed limiting components 4 are arranged at both ends of the seat plate 3. The speed limiting component 4 includes a shell 41, and the shell 41 is fixed to the seat plate 3. The front side of the shell 41 is provided with a pressure block 42 that slides elastically left and right through a spring, and the rear side of the shell 41 is provided with a friction component that slides back and forth. The surfaces of the pressure block 42 in contact with the friction component are respectively a matching V-shaped convex inclined surface and a V-shaped concave inclined surface, and a convex column 43 that passes through the shell 41 is fixed on the surface of the pressure block 42. Strips 6 are arranged on both sides of the OLED transparent screen 2, and the bottom of the strip 6 is rotatably connected to the OLED transparent screen 2. The top of the strip 6 has two clamping handles 61, and the convex column 43 is inserted between the two clamping handles 61;

[0045] Visitors hold the strip 6 and push the OLED transparent screen 2 to move left and right. The push-pull force causes the strip 6 to rotate, and the boss 43 is pushed by the handle 61 to drive the pressure block 42 to overcome the elastic force and move. The push-pull force is balanced by the elastic force exerted on the pressure block 42. The greater the push-pull force exerted on the strip 6, the greater the lateral displacement of the pressure block 42 to overcome the elastic force. The V-shaped convex surface and the V-shaped concave surface between the pressure block 42 and the friction component are in contact with each other, so that the friction component moves backward and squeezes the contact track 1 to generate friction, which is used to reduce the moving speed of the OLED transparent screen 2. The greater the push-pull force, the greater the friction, which can prevent visitors from pushing and pulling the OLED transparent screen 2 too hard and causing damage.

[0046] like Fig. 9 As shown, the friction assembly includes a friction block 44 and a push block 45. The friction block 44 passes through the shell 41 to align with the surface of the track 1. The push block 45 contacts the inclined surface of the pressure block 42. The friction block 44 and the push block 45 are connected by a rubber layer 46. The friction block 44 and the push block 45 are connected by the rubber layer 46, so that there is a flexible deformation gap between the friction block 44 and the push block 45 to prevent the friction block 44 from causing excessive wear of the track 1 due to excessive hard extrusion friction.

[0047] like Fig. 9As shown, micro switches 47 are symmetrically arranged on the left and right sides of the interior of the shell 41, and the micro switches 47 are aligned with the pressure block 42. The micro switches 47 are electrically connected to the prompt terminal. The prompt terminal can use sound prompt devices such as speakers and alarms. When tourists push the OLED transparent screen 2 too hard to cause the strip 6 to deflect by a large amplitude, the boss 43 is pushed by the clamping handle 61 to drive the pressure block 42 to move excessively, and the pressure block 42 touches the micro switch 47, so that the prompt terminal prompts the tourists to terminate the improper operation of the OLED transparent screen 2 in time, and also reminds the staff to pay attention to the protection of the equipment.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
