[0026] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.
[0027] Existing digital screens all include an upper cover, a screen assembly 300 and a lower cover 200. The screen assembly 300 is fixed to the upper cover by bonding. After the other parts are installed, the lower cover 200 is connected to the upper cover to complete the assembly of the digital screen. Because the material of the upper cover is usually plastic, it is cheap, easy to manufacture, and has high mass production. However, there is a problem of deformation of the upper cover during injection molding, especially after high-temperature baking during spraying, the deformation will be more serious, and the existing upper cover structure is relatively thin, and it is easy to deform due to excessive force or long-term use. The above will cause the glass cover to debond and warp, affecting the quality of the digital screen product.
[0028] Reference Figure 1 and Figure 2 In order to solve the above problems, the embodiment of the present application provides a reinforcement structure of the upper cover of a digital screen, which specifically includes an upper cover body 100, the front edge of the upper cover body 100 extends toward the back side to form a first reinforcement part 110, and the hollow edge in the middle of the upper cover body 100 extends toward the back side of the upper cover body 100 to form a second reinforcement part 130. Removable reinforcement members 140 are arranged on both sides of the back side of the upper cover body 100 along the long side direction, and the reinforcement members 140 are located between the first reinforcement part 110 and the second reinforcement part 130.
[0029] Since the entire upper cover body 100 (including the first reinforcement part 110 and the second reinforcement part 130) is formed by injection molding, even if the first reinforcement part 110 and the second reinforcement part 130 can solve the problem of the thinness of the upper cover body 100, the injection molding will also cause the reinforcement of the first reinforcement part 110 and the second reinforcement part 130 to fail. No matter how many integrally molded reinforcement structures are added, this problem cannot be solved, and it is more difficult to twist after deformation. The deformation problem can be better solved by adding a reinforcement part 140.
[0030] Specifically, the outer edge strength of the upper cover body 100 is strengthened by setting a first reinforcement part 110 at the edge of the upper cover body 100, and the edge strength of the middle hollow position of the upper cover body 100 is strengthened by the second reinforcement part 130, so as to improve the bearing capacity of the upper cover body 100, and then the long side of the back of the upper cover body 100 is further strengthened by the additional reinforcement 140. The reinforcement 140 installed on the upper cover body 100 can shape the upper cover body 100, effectively solve the problem of deformation of the finished upper cover body 100 during injection molding or heat treatment, and can also strengthen the anti-deformation ability of the upper cover body 100. At the same time, when the screen assembly 300 is installed on the upper cover, it is convenient for the bonding of the screen assembly 300, and it is not easy to cause excessive deformation to cause the glass cover plate 310 of the screen assembly to debond and warp after long-term use. The detachable connection of the reinforcement 140 is convenient for quick assembly on the one hand, and convenient for replacement when the reinforcement 140 fails on the other hand.
[0031] In some embodiments, Figure 3 As shown, the reinforcement 140 is made of metal, and the reinforcement 140 includes a plate-shaped first connecting plate 141, and second connecting plates 142 are symmetrically arranged on both sides of the first connecting plate 141, and the second connecting plates 142 are perpendicular to the first connecting plate 141. The plate-shaped first connecting plate 141 made of metal has higher structural strength and is not easy to deform. By setting the second connecting plate 142, the structure and deformation resistance of the first connecting plate 141 are made stronger. After being installed on the upper cover body 100, the entire reinforcement 140 can shape the deformed upper cover body 100 to a state where no deformation occurs. Specifically, the reinforcement 140 can be made of sheet metal, and a plate-shaped sheet metal is formed by bending it through a bending machine. Figure 3 The first connecting plate 141 and the second connecting plate 142 are convenient and simple to manufacture.
[0032] In some embodiments, a plurality of connecting columns (not shown in the figure) are arranged at intervals on the back side of the upper cover body 100 corresponding to the position of the reinforcement 140. When the reinforcement 140 is fixed to the back side of the upper cover body 100, the connecting columns press against the first connecting plate 141, and the second connecting plate 142 presses against the back side of the upper cover body 100. The setting of the connecting columns also reduces the local deformation of the upper cover body 100. Compared with the first connecting plate 141 directly attached to the back side of the upper cover body 100, such an installation makes the forces on the reinforcement 140 and the upper cover body 100 more balanced and the shaping effect is better.
[0033] Furthermore, the reinforcement 140 is connected to the connecting column by threads. Specifically, the connecting column is provided with a threaded hole, and the first connecting plate 141 is provided with a through hole at a position corresponding to the threaded hole. The bolts connecting the reinforcement 140 and the connecting column pass through the through hole and are threadedly connected to the threaded hole to press the first connecting plate 141 against the connecting column. The connecting column on the same side is pulled to the same plane by the first connecting plate 141, so that the long side plane of the upper cover body 100 is corrected, and then the second connecting plate 142 is further pressed against the upper cover body 100 to further share the force of the first connecting plate 141. The bolt connection makes the connection more secure and also facilitates installation and subsequent maintenance.
[0034] like Figure 2 As shown, in some embodiments, a first embedding groove 105 and a second embedding groove 106 for installing the screen assembly 300 are provided on the front side of the upper cover body 100 near the hollow position. The first embedding groove 105 is used to accommodate the glass cover plate 310 of the screen assembly 300, so that the screen assembly installed on the upper cover body 100 does not protrude from the front side of the upper cover body 100, and the overall appearance is better. The second embedding groove 106 is provided to support the display part 320 of the screen assembly 300. The entire screen assembly 300 can be supported by the combination of the first embedding groove 105 and the second embedding groove 106.
[0035] In some examples, the front side of the upper cover body 100 is concave toward the back side near the hollowed-out middle portion to form a first embedding groove 105, and the second reinforcing portion 130 borders the first embedding groove 105. Here, the overall shape of the first embedding groove 105 is adapted to the shape of the glass cover plate 310.
[0036] In some examples, a plurality of intercepting ears 150 are arranged at intervals on the edge of the second reinforcement part 130, and the intercepting ears 150 extend toward the hollow position of the upper cover body 100, and the second reinforcement part 130 and the intercepting ears 150 form a second embedding groove 106. The intercepting ears 150 arranged at intervals are not likely to cause greater deformation to the upper cover body 100 after molding.
[0037] In some examples, the groove wall of the first embedding groove 105 extends toward the back of the upper cover body 100 to form a third reinforcement portion 120, and the third reinforcement portion 120 is located between the first reinforcement portion 110 and the second reinforcement portion 130. The first reinforcement portion 110, the second reinforcement portion 130, and the third reinforcement portion 120 have similar shapes. When the reinforcement member 140 is fixed to the connecting column, the two second connecting plates 142 respectively abut against the upper cover body 100 on both sides of the third reinforcement portion 120.
[0038] In order to make the main structure of the upper cover body 100 not too thin, a plurality of first reinforcing ribs 102 are arranged at the junction of the first reinforcing portion 110 and the upper cover body 100 , a plurality of second reinforcing ribs 101 are arranged between the first reinforcing portion 110 and the third reinforcing portion 120 , and a plurality of third reinforcing ribs 103 are arranged between the second reinforcing portion 130 and the third reinforcing portion 120 .
[0039] The embodiment of the present application also provides a digital screen using the above-mentioned reinforcement structure, which specifically includes a screen assembly 300, the above-mentioned digital screen upper cover reinforcement structure and a lower cover 200. Specifically, as Figure 4 As shown, the screen assembly 300 includes a glass cover plate 310 and a display part 320. The screen assembly 300 is installed in front of the upper cover body 100. The adhesive 330 is placed on the first embedding groove 105. The display part 320 is located in the second embedding groove 106 and abuts against the intercepting ear 150. The glass cover plate 310 is bonded to the adhesive 330 of the first embedding groove 105 and then fixed to the upper cover body 100. After the remaining parts are assembled into the upper cover body 100, the lower cover 200 is covered with the upper cover body 100 to complete the assembly of the digital screen.
[0040] Furthermore, a control portion 160 for mounting the operation button 400 is disposed on one short side of the upper cover body 100 , and a docking portion 170 for placing the interface end is disposed on the other short side of the upper cover body 100 .
[0041] Specifically, a short side of the front surface of the upper cover body 100 is provided with an adapting hole 161 matching with the button, and the edge of the adapting hole 161 on the back surface of the upper cover body 100 has a reinforcing flange.
[0042] Specifically, the back side of the upper cover body 100 near the other short side is recessed toward the front side to form a receiving portion for the docking portion 170 , and the interface end is fixed to the receiving portion after the upper cover body 100 and the lower cover 200 are covered and connected.
[0043] In the embodiment of the present application, the upper cover body 100 and the lower cover 200 are connected by bolts, wherein Figure 1 As shown, a plurality of studs 104 are disposed on the back of the upper cover body 100 , and corresponding holes for the bolts to pass through are disposed on the lower cover 200 , and the upper cover body 100 and the lower cover 200 are locked and connected by threaded connection between the bolts and the studs 104 .
[0044] Among them, Figure 5 As shown, a fourth reinforcement portion 210 extends from the front edge of the lower cover 200 toward the back. The lower cover 200 is manufactured by injection molding like the upper cover body 100. When the upper cover body 100 and the lower cover 200 are covered, the fourth reinforcement portion 210 is between the first reinforcement portion 110 and the third reinforcement portion 120, and the fourth reinforcement portion 210 is against the first reinforcement portion 110.
[0045] The above-mentioned digital screen shapes the injection-molded upper cover body 100 by adding a reinforcement 140, and further improves the structural strength of the upper cover body 100 in conjunction with the first reinforcement part 110 and the second reinforcement part 130, thereby preventing the upper cover body 100 from being excessively deformed during use, and making it less likely for the glass cover plate 310 of the screen assembly 300 bonded to the upper cover body 100 to become debonded and warped.
[0046] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
