Description

Technical Field

[0001] This utility model relates to the technical field of smart screen protection equipment, specifically a flip-chip COB smart screen dustproof sealing cover. Background Technology

[0002] With the continuous development of display technology, flip-chip COB smart screens have been widely used in many fields such as conference presentations, education and training, and home theaters due to their advantages of high brightness, high contrast and low power consumption. However, the precision electronic components and light-emitting units of flip-chip COB smart screens are quite sensitive to environmental factors such as dust and moisture. Dust may cause short circuits and degrade the display effect, while moisture may corrode the circuit board, affecting the lifespan and stability of the smart screen. Therefore, effective dustproof sealing protection for flip-chip COB smart screens is crucial.

[0003] Currently, most common dustproof sealing methods on the market involve directly fixing the sealing strip to the edge of the cover. When installing and removing the sealing strip, operators need to directly contact the edge of the smart screen, which can easily cause physical damage such as scratches and compression to the smart screen. In addition, since the sealing strip has a certain degree of shrinkage, it is cumbersome to put the sealing strip around the smart screen, which is not conducive to improving production and maintenance efficiency. Therefore, this utility model proposes an inverted COB smart screen dustproof sealing cover to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an inverted COB smart screen dustproof sealing cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and sealing cover for an inverted COB smart screen, comprising a cover body, wherein the cover body has an internal hollow structure, a power supply board is installed inside the cover body, and magnetic disks are provided at the four corners of the power supply board, wherein the magnetic disks are used to install the inverted COB smart screen;

[0006] An elastic sealing strip is provided on one edge of the opening of the cover, and the elastic sealing strip is used to wrap the COB smart screen.

[0007] An auxiliary structure is provided inside the cover. The auxiliary structure includes two auxiliary plates, which are respectively connected to the adjustment plates. The two adjustment plates are provided with toothed grooves. The two adjustment plates are arranged opposite each other and an adjustment tooth is provided between the two adjustment plates. The adjustment tooth engages with the toothed groove at the right end of the upper adjustment plate and with the toothed groove at the left side of the lower adjustment plate. The adjustment tooth is installed on the side wall of the cover with a stud. One end of the stud is connected to the adjustment handle.

[0008] By rotating the adjusting handle, the adjusting teeth are rotated, which in turn moves the auxiliary plates at both ends to the outside of the cavities on both sides of the cover, allowing the elastic sealing strip to expand and contract, thus facilitating the installation and removal of the elastic sealing strip.

[0009] Preferably, two sets of guide grooves are respectively provided above and below the middle position of the inner wall of the cover, and the two sets of adjustment plates are respectively provided above and below, with the protrusions integrally formed at their ends embedded in the guide grooves, so that the adjustment plates can be slidably installed on the cover along the guide grooves.

[0010] Preferably, the size of the auxiliary plate is adapted to the size of the cavities on both sides of the cover.

[0011] Preferably, heat dissipation cavities are provided at the upper and lower ends of the cover, and filter plates are provided in the heat dissipation cavities. The filter plates are installed in the corresponding upper and lower heat dissipation cavities by snapping.

[0012] Preferably, a heat sink is installed on the side wall of the cover, and the heat sink is installed in the middle position between the two power supply boards via a positioning plate.

[0013] Preferably, the cover is mounted on a fixed frame, and the fixed frame is kept at a certain distance from the ground.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting an auxiliary structure inside the cover, the expansion and contraction of the elastic sealing strip can be realized by using the linkage structure of the adjustment handle, adjustment teeth, adjustment plate and auxiliary plate. When installing and disassembling the elastic sealing strip, the operator does not need to directly contact the edge of the smart screen, which effectively avoids physical damage such as scratches and squeezing caused by human operation, protects the structural integrity and display effect of the flip-chip COB smart screen, and extends the service life of the smart screen.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a dustproof and sealing cover for an inverted COB smart screen, including a cover body 1, which has an internal hollow structure. A power supply board 11 is installed inside the cover body 1, and magnetic disks 12 are provided at the four corners of the power supply board 11 for mounting the inverted COB smart screen 2; an elastic sealing strip 3 is provided on one edge of the opening of the cover body 1, and the elastic sealing strip 3 is used to wrap the COB smart screen 2; an auxiliary structure 4 is provided inside the cover body 1, and the auxiliary structure 4 includes two auxiliary plates 41, which are respectively connected to an adjustment plate 42. Each adjusting plate 42 has a toothed groove, and two adjusting plates 42 are arranged opposite each other. An adjusting tooth 43 is provided between the two adjusting plates 42. The adjusting tooth 43 engages with the toothed groove at the right end of the upper adjusting plate 42 and with the toothed groove at the left side of the lower adjusting plate 42. The adjusting tooth 43 is installed on the side wall of the cover 1 with a stud. One end of the stud is connected to the adjusting handle 44. By rotating the adjusting handle 44, the adjusting tooth 43 is driven to rotate, which in turn drives the auxiliary plates 41 at both ends to move to the outside of the cavities on both sides of the cover 1, so that the elastic sealing strip 3 expands and contracts, which facilitates the installation and removal of the elastic sealing strip 3.

[0023] Please see Figures 1 to 4 Two sets of guide grooves 111 are respectively provided above and below the middle position of the inner wall of the cover 1. Two sets of adjustment plates 42 are arranged vertically and vertically respectively. The protrusions 421 integrally formed at their ends are embedded in the guide grooves 111, so that the adjustment plates 42 can be slidably installed on the cover 1 along the guide grooves 111.

[0024] By cooperating with the protrusion 421 at the end of the adjusting plate 42 through the two sets of guide grooves 111, precise guidance can be provided for the sliding of the adjusting plate 42, effectively preventing the adjusting plate 42 from shifting, shaking or getting stuck during the movement, ensuring that the auxiliary plate 41 can smoothly and accurately drive the elastic sealing strip 3 to expand and contract, and ensuring the smooth installation and disassembly of the dustproof sealing cover.

[0025] Please see Figures 1 to 4 The size of the auxiliary plate 41 is adapted to the size of the two side cavities of the cover 1.

[0026] Please see Figures 1 to 4 Heat dissipation cavities 13 are provided at the upper and lower ends of the cover 1, and filter plates 14 are provided in the heat dissipation cavities 13. The filter plates 14 are installed in the corresponding upper and lower heat dissipation cavities 13 by snapping.

[0027] Please see Figures 1 to 4 A heat sink 5 is installed on the side wall of the cover 1. The heat sink 5 is installed in the middle position between the two power supply boards 11 through a positioning plate.

[0028] Please see Figures 1 to 4 The cover 1 is installed on the fixed frame 6, and the fixed frame 6 is kept at a certain distance from the ground.

[0029] In use, install the mounting bracket 6 in a suitable position, keeping it a certain distance from the ground. Then, install the cover 1 onto the mounting bracket 6. Next, use the magnetic disks 12 at the four corners of the power supply board 11 to attach the inverted COB smart screen 2 to the power supply board 11 inside the cover 1. Rotate the adjusting handle 44, which drives the stud to rotate, causing the adjusting tooth 43 connected to one end of the stud to rotate. Since the adjusting tooth 43 meshes with the tooth groove on the adjusting plate 42, when the adjusting tooth 43 rotates, it drives the adjusting plates 42 at both ends to move to the sides. The protrusion 421 at the end of the adjusting plate 42 slides along the guide groove 111. When the adjusting plate 42 moves, it drives the auxiliary plate 41 connected to it to extend to the outside of the two side cavities of the cover 1. At this time, the elastic sealing strip 3 expands, and the expanded elastic sealing strip... The sealing strip 3 is installed on the auxiliary plates 41 at both ends. Then, the adjusting handle 44 is reversed, causing the auxiliary plates 41 to drive the elastic sealing strip 3 to retract and fit over the edge of the COB smart screen 2, thus completing the seal. When the inverted COB smart screen 2 is working, the heat dissipation cavities 13 at the upper and lower ends of the cover 1, together with the heat sink 5 installed on the side wall, dissipate the heat generated by the smart screen. The filter plate 14 in the heat dissipation cavity 13 can prevent dust and other impurities from entering the interior of the cover 1. When it is necessary to maintain or replace the elastic sealing strip 3 of the inverted COB smart screen 2, the adjusting handle 44 is rotated, and the adjusting gear 43 rotates again, causing the auxiliary plate 41 to expand, so that the elastic sealing strip 3 is removed from the edge of the COB smart screen 2. Since the disassembly process does not require direct contact with the COB smart screen 2, damage to the smart screen can be avoided.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
