[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0035] Please see Figure 1 and Figure 9 This utility model provides a double-sided advertising machine, including: a frame 10, an LED light strip 20, a light guide plate 30, and a display screen 40.

[0036] The LED light strip 20, light guide plate 30, and display screen 40 are all mounted on the frame 10, with the light strip's light emission direction facing the light guide plate 30, and the light guide plate 30's light emission direction facing the display screen 40. The display screen 40 has a first display surface and a second display surface, located on opposite sides of the display screen 40. This utility model of a double-sided advertising machine fixes the LED light strip 20, light guide plate 30, and display screen 40 to the frame 10, and sets opposite sides of the display screen 40 to have a first display surface and a second display surface. The advertising machine can achieve double-sided display function using only one display screen 40, greatly reducing the overall thickness of the advertising machine, minimizing its footprint, and lowering operating costs.

[0037] In short, traditional double-sided advertising machines are spliced ​​double-sided screens. That is, two display screens 40 are spliced ​​back to back, and each display screen 40 is equipped with a corresponding light guide plate 30. This application, however, is a single-screen dual-display, using only one light guide plate 30 and one display screen 40. The light guide plate 30 can guide light to the first and second display surfaces of the display screen 40, saving one light guide plate 30 and one display screen 40, simplifying the structure and reducing the thickness.

[0038] The first display surface and the second display surface are the front and rear of the display screen 40, respectively. Both the first and second display surfaces are used to display the same or different graphic images.

[0039] The frame 10 includes a frame 11, a middle mounting plate 12, and two horizontal sheet metal strips 13. The middle mounting plate 12 and the two horizontal sheet metal strips 13 are disposed on the frame 11, and the middle mounting plate 12 is disposed between the two horizontal sheet metal strips 13.

[0040] Please see Figure 2 , Figure 3 and Figure 9 The frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 arranged sequentially from front to back. The front frame 111 and the middle frame 112 are detachably connected, and the middle frame 112 and the rear frame 113 are detachably connected. This facilitates the assembly of the light guide plate 30 and the display screen 40 onto the frame 11.

[0041] Please see Figure 4 The front frame 111 has a first fixing hole 1111 on its side, the rear frame 113 has a second fixing hole 1131 on its side, and the middle frame 112 has a third fixing hole that matches either the first fixing hole 1111 or the second fixing hole 1131 on its side. A locking screw is inserted through the first fixing hole 1111 and the third fixing hole to fix the front frame 111 to the middle frame 112; a locking screw is inserted through the second fixing hole 1131 and the third fixing hole to fix the rear frame 113 to the middle frame 112. Thus, neither the first fixing hole 1111 nor the second fixing hole 1131 is coplanar with the first or second display surface of the display screen 40, and the third fixing hole is located inside the frame 11, resulting in a flat and aesthetically pleasing appearance for the double-sided advertising machine.

[0042] The front frame 111 and the rear frame 113 are spaced apart, and a heat dissipation groove 115 is formed between the front frame 111 and the rear frame 113. The heat dissipation groove 115 can help dissipate heat from the electronic components inside the double-sided advertising machine, thereby improving the stability of the double-sided advertising machine during operation.

[0043] Please refer to it again. Figure 2 and Figure 3 The middle frame 112 is provided with two suspension parts 14, both of which extend from the same direction. In this way, the suspension parts 14 provide installation positions for cables to suspend the entire double-sided advertising machine at a fixed height, making it convenient for users to observe and operate the first and second display surfaces of the display screen 40.

[0044] Please see Figure 5 and Figure 6 Furthermore, the middle frame 112 includes four connecting mounting strips at both ends, with corner brackets 114 provided between adjacent mounting strips. The corner brackets 114 can restrict the four mounting strips to be on the same plane, so that the middle frame 112 maintains the shape of the rectangular frame 11, the installation of the light guide plate is more stable, there is no dent after the LCD screen is installed, and the screen is flatter.

[0045] Specifically, each mounting strip of the middle frame 112 includes a mounting portion 1121 and a heat dissipation portion 1122. The heat dissipation portion 1122 is disposed on the mounting portion 1121 and extends toward the inside of the mounting portion 1121.

[0046] The mounting section 1121 has a mounting groove 1123 for accommodating the corner bracket 114. The mounting groove 1123 is a through groove. The corner bracket 114 has an L-shaped structure, with its two ends inserted into the two mounting grooves 1123 of two adjacent mounting sections 1121. In this way, the corner bracket 114 serves to connect the mounting strips, so that the four mounting strips of the middle frame 112 are on the same plane.

[0047] Please see Figure 7 and Figure 8 The corner bracket 114 has two sets of first mounting holes 1141, with four holes in each set, arranged in a square. The mounting part 1121 has second mounting holes 1124 that are adapted to the first mounting holes 1141. That is, both ends of the mounting part 1121 have four second mounting holes 1124. The mounting strip is fixedly connected to the corner bracket 114 by locking bolts passing through the first mounting holes and the second mounting holes 1124.

[0048] The heat dissipation section 1122 has multiple protrusions, which are spaced apart from each other, and a heat dissipation channel is formed between two adjacent protrusions. The heat dissipation channel is filled with air to prevent heat from being transferred from the middle frame 112 to the front frame 111 or the rear frame 113, and the heat dissipation channel can dissipate the heat inside the double-sided advertising machine to the outside, thereby improving the stability of the double-sided advertising machine in operation.

[0049] Furthermore, the bottom wall, side wall, and top wall of the mounting portion 1121 together form a light strip mounting groove (not shown). The LED light strip 20 is disposed on the side wall of the mounting portion 1121 and located within the light strip mounting groove. The light strip mounting groove has a lateral opening, and the light-emitting direction of the LED light strip 20 is oriented towards the lateral opening.

[0050] Both ends of the light guide plate 30 are respectively secured in the two LED strip mounting slots 1123 to ensure that the light guide plate 30 is fixed stably and reliably. The light emission direction of the LED strip 20 is set towards the side opening, that is, the light emission direction of the LED strip 20 is set towards the light guide plate 30.

[0051] The display screen 40 is mounted on the light guide plate 30, which contains a vertical light path. The input end of the light path faces the LED light strip 20, and the output end faces the display screen 40. The display screen 40 has a first display surface and a second display surface. The first display surface faces outward, and the second display surface faces the light guide plate 30. Light emitted from the LED light strip 20 passes through the light guide plate 30 and is projected onto the first and second display surfaces of the display screen 40.

[0052] Please see Figure 10 and Figure 11In one specific embodiment, a first receiving groove 121 is formed by an inward recess on one side of the intermediate mounting plate 12, and a second receiving groove 131 is formed by an inward recess on one side of the two horizontal sheet metal strips 13. The openings 123 of the first receiving groove 121 and the second receiving groove 131 are in the same direction. Both the first receiving groove 121 and the second receiving groove 131 are used to place the light guide plate 30. In this way, the light guide plate 30 is limited by the first receiving groove 121 and the second receiving groove 131, making the installation of the light guide plate 30 more stable. Secondly, the first receiving groove 121 and the second receiving groove 131 can make full use of the internal space of the double-sided advertising machine, further reducing the overall thickness of the equipment.

[0053] The depths of the first receiving groove 121 and the second receiving groove 131 are configured to accommodate light guide plates of the same thickness. The light guide plate 30 is a single piece, placed in the first receiving groove 121 of an intermediate mounting plate 12 and the second receiving groove 131 of two horizontal sheet metal strips 13.

[0054] In one specific embodiment, two first wire-passing grooves 122 are formed on the intermediate mounting plate 12, and two second wire-passing grooves 132 are formed on the horizontal sheet metal 13. The two first wire-passing grooves 122 and the two second wire-passing grooves 132 are generally aligned in a straight line. Two through holes (not shown) are also formed on the frame 11. Thus, after the cable enters the double-sided advertising machine through one through hole, it exits through the other through hole under the combined limiting effect of the first and second wire-passing grooves 122 and 132, ensuring stable and reliable installation and improving the stability of electrical signal transmission.

[0055] Furthermore, one of its cable entry ports is located on the front side of the double-sided advertising machine, and the other cable entry port is located on the rear side, so that the first cable tray 122 and the second cable tray 132 can control the cable to run from the front to the rear side inside the device.

[0056] In one specific embodiment, an opening 123 is formed on the intermediate mounting plate 12, and a support plate 124 is disposed at the opening 123. The support plate 124 is used to support the logic board of the LCD screen.

[0057] The middle mounting plate 12 has two first ends 125 at each end, and both first ends 125 are fixed to the heat dissipation part 1122 of the middle frame 112. The first ends 125 are fixed to the heat dissipation part 1122 by screws, and the second ends 133 and the horizontal sheet metal 13 are fastened by screws.

[0058] In one specific embodiment, each of the two horizontal sheet metal 13 has two second end portions 133 at both ends, and the two second end portions 133 are fixed to the heat dissipation portion 1122 of the middle frame 112.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
