Description

Technical Field

[0001] This utility model belongs to the field of LED transparent screen technology, and specifically relates to an LED transparent screen. Background Technology

[0002] As the name suggests, LED transparent screens are products developed by LED displays to achieve better transparency and reduce or modify materials. These screens are mostly used in places where glass is installed, hence the name "film-coated screens." It's a display technology that attaches LED chips to a transparent substrate. It consists of LED chips, driving circuits, a control system, and optical structures. By attaching LED chips to a transparent substrate, film-coated screens can achieve high transparency, high brightness, and high contrast display effects, and are widely used in commercial displays, outdoor advertising, stage backdrops, and other fields.

[0003] Currently, the transparent light panels of LED transparent screens are generally connected directly to the PCB board inside the control box via connecting wires. Therefore, when the transparent light panels are hoisted, the connecting wires will be subjected to the pulling force of gravity on the transparent light panels, which can easily lead to the risk of the wires coming loose. Some systems connect the wires and then use sealant to fix the transparent light panels to the housing of the control box, but this will cause trouble for the subsequent disassembly and maintenance of the transparent light panels.

[0004] In view of this, the present invention provides an LED transparent screen to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED transparent screen, comprising:

[0006] Transparent light panel; and

[0007] A control box includes a box body and a PCB board installed inside the box body. A clip is formed on the surface of the box body, and one edge of a transparent light panel is inserted into the clip and electrically connected to the PCB board inside the box body.

[0008] The spacing between the clamps is less than the thickness of the transparent light panel, so that the clamps can hold the transparent light panel and restrict the relative movement between the transparent light panel and the control box.

[0009] Preferably, the box body is provided with a hanging bracket connecting block and a PCB hanging bracket connected to the hanging bracket connecting block for mounting the PCB board.

[0010] Preferably, the box body includes: a main box body, and a shell rear cover that is slidably and detachably connected to the main box body, wherein the clamp is formed between the main box body and the shell rear cover.

[0011] Preferably, the main housing is provided with a slider, and the rear cover of the housing is provided with a groove that is slidably connected to the slider.

[0012] Preferably, the end of the main box is fitted with a stopper to restrict relative sliding between the main box and the rear cover of the housing.

[0013] Preferably, at least one set of lifting lugs can be movably connected to the surface of the box body away from the clamp.

[0014] Preferably, it further includes a second box body connected to the other edge of the transparent light panel and having the same structure as the box body, and a side frame that is connected between the second box body and the box body via connecting ears to form an enclosure of the transparent light panel.

[0015] Preferably, the box body and the second box body have an insertion port on their end faces relative to the side frame;

[0016] The connecting ear has a first fitting part and a second fitting part that are integrally connected and respectively attached to the surface of the box body and the side frame. The first fitting part and the second fitting part are respectively connected and fixed to the box body and the side frame by fasteners.

[0017] Preferably, a slidable frame is connected to the outer periphery of the box or the second box.

[0018] Preferably, the top of the omnidirectional mobile frame is provided with a through groove that is adapted to the outer periphery of the box or the second box, and omnidirectional wheels are provided at the bottom of its frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model provides a clamping opening on the surface of the control box with a spacing smaller than the thickness of the transparent light board. When the transparent light board is connected to the PCB board inside the control box, the clamping opening can hold and fix the transparent light board. Thus, during hoisting, the clamping opening can overcome the weight of the transparent light board, thereby effectively reducing the possibility of the wiring coming loose.

[0021] 2. This utility model allows for easy disassembly of the control box by directly sliding the main box body and the rear cover of the housing, thereby improving the convenience of subsequent maintenance.

[0022] 3. This utility model enables the hanging and standing placement of LED transparent screens through the connection between the hanging lugs, the omnidirectional mobile frame and the box body. Attached Figure Description

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

[0034] Example 1:

[0035] This utility model relates to an LED transparent screen, such as Figures 1-3 As shown, it includes a transparent light panel 1 and a control box 2 electrically connected to the transparent light panel 1.

[0036] The transparent light panel 1 uses a flexible holographic LED screen or a crystal film screen; the control box 2 includes a box body consisting of a main box body 21 and a housing cover 22 detachably connected to the main box body 21, such as... Figures 2-3 As shown, at least one bracket connecting block 212 is provided inside the main box 21. A PCB bracket 213 for mounting a PCB board is connected to the bracket connecting block 212. The transparent light board 1 is electrically connected to the PCB board mounted on the PCB bracket 213 through wiring.

[0037] like Figure 3 As shown, the main housing 21 is provided with an "L"-shaped slider 211 extending along the length of the main housing 21. The rear cover 22 of the housing is provided with a groove 221 that matches the slider 211. By sliding the slider 211 into the groove 221, the main housing 21 and the rear cover 22 of the housing can be slidably connected and fixed together. At the sliding connection point away from the two, the main housing 21 and the rear cover 22 of the housing are spaced apart to form a clamping opening 23. The size of the clamping opening 23 is slightly smaller than the thickness of the transparent light panel 1, so that when the edge of the transparent light panel 1 is electrically connected to the PCB board, the clamping opening 23 can form a clamping force on the transparent light panel 1, thereby fixing the transparent light panel 1 and restricting its movement.

[0038] A sliding lug groove 215 extending rectangularly along the length of the main box 21 away from the clamp 23 is provided on the other end face of the main box 21. The sliding lug groove 215 is T-shaped, and a lug 25 that matches its T-shaped structure can be slidably fitted from the end of the main box 21. Figure 2 As shown. By installing the lugs 25 and adjusting them within the lug sliding grooves 215, the entire LED transparent screen can be easily suspended for use, similar to many projection screens currently available.

[0039] Furthermore, to limit the relative movement between the rear cover 22 and the main housing 21, and to prevent the lifting lug 25 from sliding out of the lifting lug sliding groove 215, a stopper 24 is installed at the end of the main housing 21. The stopper 24 can cover the end face of the main housing 21, thereby sealing the ends of the lifting lug sliding groove 215 and the sliding groove 221, thus sealing the respective slidingly connected components within their grooves and preventing them from coming out. Meanwhile, if... Figure 2 As shown, a second positioning hole 222 and a first positioning hole 214 are respectively provided at the connection surface where the rear cover 22 of the housing and the main box 21 are slidably connected. They are connected by the connecting ear 4.

[0040] Specifically, a threaded hole is provided at the top corner of the end face of the main body 21, and a through hole is provided on the plug 24 corresponding to the threaded hole. A bolt is inserted into the through hole and connected to the threaded hole to fix the plug 24. Figure 5As shown, the connecting ear 4 has a first fitting portion that can simultaneously fit the second positioning hole 222 and the first positioning hole 214. The first fitting portion has through holes corresponding to the second positioning hole 222 and the first positioning hole 214, respectively. Using the same design as the plug 24, the first fitting portion is connected to the second positioning hole 222 and the first positioning hole 214 with bolts, thereby further restricting the movement of the rear cover 22 of the housing in conjunction with the plug 24.

[0041] Example 2:

[0042] Based on the above embodiment one, this embodiment also provides an additional vertical installation structure for the LED transparent screen.

[0043] like Figures 4-7 As shown, the LED transparent screen also includes a second box 5 connected to the other edge of the transparent light panel 1 and having the same structure as the box body, and a side frame 3 formed by connecting ears 4 between the second box 5 and the box body to enclose the transparent light panel 1.

[0044] The box body has a slot 26 on its surface relative to the side frame 3, which communicates with the end face of the side frame 3. The end of the side frame 3 can be inserted into the box body through this slot 26. A second fitting part is also integrally connected to the first fitting part of the connecting ear 4, such as... Figure 5 As shown, the second fitting part is used to fit against the surface of the side frame 3. It is connected to the side frame 3 by bolt fixing in the same way as the first fitting part and the plug 24, thereby preventing the side frame 3 from detaching from the socket 26. Through the installation of the side frame 3 and the second box 5, together with the control box 2, a frame is formed to surround the transparent light panel 1.

[0045] Simultaneously, the omnidirectional movable frame 6 is slidably connected to the outer periphery of the second box 5 or the control box 2, preferably, as follows: Figure 8 As shown, the top of the omnidirectional mobile frame 6 is provided with a concave through groove 61 that fits the outer periphery of the box body or the second box body 5, and four sets of universal wheels 62 are provided at the bottom of its frame body. In use, by inserting the second box body 5 or the box body of the control box 2 into the through groove 61, the LED transparent screen can be used in a standing position and moved conveniently by means of the support of the omnidirectional mobile frame 6 and the universal wheels 62 at its bottom.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
