Description

Technical Field

[0001] The present invention belongs to the technical field of all-in-one machines, and particularly relates to a double-sided display device. Background Art

[0002] A display is an electronic device used to display images and colors, and is widely used in various fields, such as the advertising field, the entertainment field, or the office field, etc. The sizes of displays are also diverse. Currently, the general mainstream sizes are 17", 19", 21", 22", 24", and 27", etc. Common displays generally can only perform single-screen display, that is, there is only one liquid crystal display screen on it. With the increasingly wide application of displays, their application scenarios are becoming more and more complex. Sometimes people hope that both the front and back of the display can be used for display to achieve double-sided display. For this, users mostly use two displays to achieve double-sided display. And with the increase in demand, there are now displays on the market that install two displays on the same bracket to achieve double-sided display. However, the production cost of this structure of display is relatively high, the volume is large, it requires a large placement space, and the weight is also large, increasing the transportation cost, and the market competitiveness is weak.

[0003] Based on the above problems, the prior art discloses a single-machine double-sided screen display structure (patent application number: 202120862000.8), which includes a first liquid crystal screen, a second liquid crystal screen, a light bar, a backplane, a light guide plate, a first dimming structure, a second dimming structure, a main board structure, and a bracket. The first liquid crystal screen and the second liquid crystal screen are both installed on the bracket and are both connected to the main board structure. The light bar, the backplane, the light guide plate, the first dimming structure, the second dimming structure, and the main board structure are all arranged inside the bracket. The light bar is located below the backplane. The light guide plate is connected to one side of the backplane. The first dimming structure is connected to the other side of the backplane. The second dimming structure is connected to the light guide plate. The back of the first liquid crystal screen faces the first dimming structure, and the back of the second liquid crystal screen faces the second dimming structure. Compared with the setting of two displays on the market, this technology can greatly reduce the required design volume and placement space. At the same time, it can also reduce the overall mass, lower the transportation cost, and has strong market competitiveness.

[0004] However, the above technology cannot achieve convenient disassembly of the structure while achieving a compact structure, and the volume of the product can be further reduced to make the structure more compact. Summary of the Invention

[0005] To solve the above problems, the primary object of the present invention is to provide a double-sided display device with a compact structure and convenient installation and disassembly.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A double-sided display device, characterized in that it includes a double-sided screen, a fixing block and a base. An installation groove is formed on the top surface of the fixing block, the double-sided screen is detachably installed on the installation groove, fixing holes are provided on the bottom surface of the fixing block, and the base is detachably connected to the fixing holes. A first accommodation cavity is formed on one side surface of the fixing block, and a first PCB board is arranged in the first accommodation cavity. The first PCB board is electrically connected to the double-sided screen; a second accommodation cavity is formed on the other side of the fixing block, and a second PCB board is arranged in the second accommodation cavity. The second PCB board is electrically connected to the double-sided screen.

[0008] In the present invention, by reasonably utilizing each surface of the fixing block and ingeniously arranging the installation groove, fixing holes, first accommodation cavity and second accommodation cavity, as many structures as possible can be arranged in a relatively small space, achieving a further compact structure effect compared with the prior art. Moreover, the overall structure is convenient for installation and disassembly, facilitating production, processing and maintenance.

[0009] Further, the installation groove is formed in the middle of the top surface of the fixing block, and the first accommodation cavity and the second accommodation cavity are symmetrically distributed on both sides of the installation groove. The above settings of the installation groove, first accommodation cavity and second accommodation cavity can make the overall center of gravity of the structure more stable and the finished product has good stability after installation.

[0010] Furthermore, after the installation groove is formed on the fixing block, the fixing block as a whole is U-shaped. Such a structure can very ingeniously arrange other structures, such as arranging fixing holes on the bottom surface of the U-shape and arranging the first accommodation cavity and the second accommodation cavity on the two side surfaces of the U-shape respectively. On the basis of compactly arranging the above structures, the various structures do not interfere with each other and cooperate ingeniously to realize their respective functions.

[0011] Further, the fixing block further includes a first cover plate and a second cover plate. The first cover plate covers the first accommodation cavity, and the second cover plate covers the second accommodation cavity.

[0012] Further, a plurality of heat dissipation holes are provided on the fixing block, and the heat dissipation holes are respectively communicated with the first accommodation cavity and the second accommodation cavity. The setting of the heat dissipation holes can better improve the heat dissipation effect of the PCB board. Moreover, due to the existence of the base, the fixing block has a certain height, and there is no need to worry about waterproof problems.

[0013] Further, a first communication hole is arranged in the first accommodation cavity, a second communication hole is arranged in the second accommodation cavity, and both the first communication hole and the second communication hole penetrate through to the installation groove. The setting of the first communication hole and the second communication hole can facilitate the wiring of the PCB board.

[0014] Furthermore, the base includes a workbench and a column. One end of the column is detachably connected to the fixing hole, and the other end of the column is connected to the workbench. The workbench mainly serves as a support, and the column is used to raise the height of the double-sided screen. Selecting columns of different lengths can conveniently adjust the display height of the double-sided screen. Preferably, one end of the column is detachably connected to the fixing hole by means of a thread.

[0015] Furthermore, the base further includes a fixing ring provided with internal threads. The other end of the column passes through the workbench and is threadedly connected to the fixing ring. The design of the fixing ring facilitates fixing the column on the workbench and also facilitates disassembly.

[0016] Furthermore, the internal threads of the fixing ring penetrate through the fixing ring. The internal threads penetrating through the fixing ring enable the fixing ring to be screwed into the column. By adjusting the depth of the fixing ring screwed into the column, the height of the column can be adjusted to a certain extent, and thus the display height of the double-sided screen can be adjusted.

[0017] Furthermore, a wire routing hole penetrating through the column is provided inside the column, and both ends of the wire routing hole are communicated with the fixing hole and the fixing ring respectively. Providing the wire routing hole inside the column can facilitate wire routing and prevent the wires from being exposed.

[0018] Furthermore, the double-sided screen includes a first display screen, a second display screen, a middle frame, a light guide plate, and a light bar. The first display screen and the second display screen are both installed inside the middle frame, and the first display screen, the second display screen, and the middle frame enclose a light guide space. The light guide plate and the light bar are both installed inside the light guide space. Through the cooperation of the light guide plate and the light bar, only one light bar is needed to achieve the normal display of the first display screen and the second display screen, which has the advantage of energy saving. That is, through the new structure, the present invention can achieve the display of two screens with only one set of backlight, consuming less energy and using less materials compared with the prior art, and having the effect of low-carbon energy saving.

[0019] Furthermore, the double-sided screen further includes a decorative face cover. The decorative face cover is U-shaped. The first display screen, the second display screen, and the middle frame are all clamped in the U-shaped groove of the decorative face cover, and the decorative face cover is clamped in the installation groove. Setting the U-shaped decorative face cover can, on the one hand, strengthen the fixing stability among the first display screen, the second display screen, and the middle frame, and on the other hand, facilitate matching with the installation groove to achieve convenient disassembly and assembly of the double-sided screen. The decorative face cover is made of a metal material, preferably an aluminum material, which has a good heat dissipation effect and can effectively dissipate heat from the light bar.

[0020] The advantages of the present invention are as follows: Compared with the prior art, in the present invention, by reasonably utilizing each surface of the fixed block and skillfully arranging the installation groove, the fixing hole, the first accommodating cavity and the second accommodating cavity, as many structures as possible can be arranged in a relatively small space, achieving a further compact structure effect compared with the prior art, and the overall structure is convenient for installation, disassembly, production, processing and maintenance.
