[0028] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0029] In view of the technical problems existing in the prior art, the present invention provides a display device having a matching circuit board with two terminal interfaces, side-out and back-out. Figure 1-9 As shown, the display device includes a back plate 21 for supporting a display module, a circuit board 22 with connecting terminals is provided on the back plate 21, and the connecting terminals include a first terminal 23 extending in a direction parallel to the light-emitting surface of the display module, and a second terminal 24 extending in a direction perpendicular to the light-emitting surface of the display module; a first shell 1, which is connected with the back plate 21 to form a first receiving space, and the circuit board 22 is located in the first receiving space, the first shell 1 includes a flat plate portion 2 and a first side wall 3 extending along the edge of the flat plate portion 2, a first through hole 4 corresponding to the first terminal 23 is provided on the first side wall 3, and the first terminal 23 extends from the first through hole 4, the flat plate portion 2 is provided with an opening 5, and the area of ​​the opening 5 covers the position where the second terminal 24 is located; and a cover plate 6, which is fixed in the opening 5, and a second through hole 7 corresponding to the second terminal 24 is provided on the cover plate 6, and the second terminal extends from the second through hole 7.

[0030] The present invention utilizes the cooperation between the first housing 1 and the back plate to accommodate and protect the circuit board with the connecting terminal in the first accommodation space; the first through hole 4 on the side wall of the first housing 1 is matched with the first terminal 23, so that the first terminal 23 extends from the first through hole 4, and it is no longer necessary to additionally make a terminal cover plate matching the first terminal 23, thereby reducing a set of sheet metal molds, reducing mold costs, and at the same time being able to improve assembly efficiency and meet safety requirements, thereby greatly reducing the economic cost and labor cost of the whole machine; in addition, the opening 5 is matched with the cover plate 6, and a second through hole 7 is provided on the cover plate 6, so that the second terminal 24 extends from the second through hole 7, achieving the effect of simple structural design, convenient disassembly and assembly, and easy replacement of the cover plate 6; after the first housing 1 is buckled onto the back plate, the tongue of the first housing 1 is slid into the slot along the extension direction of the first terminal 23, at this time, the second terminal 24 is located in the area of ​​the opening 5, the second terminal 24 will not contact the first housing 1, so that the second terminal 24 will not interfere with the sliding fixation of the first housing 1, therefore, the area of ​​the opening 5 is slightly larger than the area where the second terminal is located. In addition, the present invention can simultaneously match two types of terminal interfaces, namely, side-outlet and rear-outlet, and has low cost and good appearance.

[0031] When the present invention is matched with a display device whose circuit board has two terminal interfaces, side-out and back-out, the first shell 1 and the cover plate 6 are arranged to realize one-step assembly, and there is no need to install the rear shell, which effectively reduces the design cost and has a better appearance. Moreover, the problem of possible interference between the second terminal and the first shell 1 is solved by the quick assembly between the cover plate 6 and the first shell 1. That is to say, a second through hole 7 is provided on the cover plate 6. When the second through hole 7 on the cover plate 6 is tried to match with the second terminal 24, if the relative hole positions of the two are correct, the cover plate 6 is directly inserted and fixed in the opening 5 of the second shell 8; if the relative hole positions of the two are offset, the second through hole 7 on the cover plate 6 can be directly modified until the hole positions are on the same center line.

[0032] It should be noted that the display module in the present application is used to display images or videos, and the side displaying the images or videos is the light-emitting side, the first terminal 23 is a side-emitting terminal, and the second terminal 24 is a back-emitting terminal.

[0033] In addition, the connection terminals of the present application include not only audio and video terminals, but also other signal terminals such as power input port, HDMI interface, RF45 interface, RF terminal, etc. The shapes of the connection terminals can be the same or different. The central axes of the first through hole 4 and the second through hole 7 coincide with the central axes of the first terminal and the second terminal, respectively. The diameters of the first through hole 4 and the second through hole 7 coincide with the diameters of the first terminal 23 and the second terminal 24, respectively, so that the connection terminals can just pass through the through holes. Since the shapes of the connection terminals can be the same or different, accordingly, the shape of the through hole corresponding to each connection terminal also needs to be set according to the shape of the connection terminal.

[0034] Those skilled in the art will appreciate that the first shell 1 and the back plate are detachably fixedly connected, such as by screwing or snapping, so that the first shell 1 and the back plate can be easily disassembled and assembled, thereby allowing for various adjustments when necessary.

[0035] The circuit board with connecting terminals in the present invention realizes input and output signals through the first terminal 23 and the second terminal 24, and is an indispensable part of the display module. Therefore, it needs to be covered by the first shell 1 and the back plate to play a role of protection and isolation. At the same time, the opening 5 can cover the position where the second terminal is located.

[0036] In an optional embodiment, if Figure 1-4 , Figure 7As shown, the second housing 8 connected to the back plate of the display module is also included, the second housing 8 and the back plate together form a second receiving space, the second receiving space accommodates the speaker assembly, and the second housing 8 is connected to the first housing 1. By separately accommodating the speaker assembly in the second receiving space, the connection terminal and the speaker assembly can be arranged in a partitioned manner, and the space in the non-light-emitting surface direction of the display module can be reasonably utilized, which is convenient for rapid disassembly and maintenance.

[0037] More specifically, if Figure 5 As shown, the first side wall 3 of the first shell 1 is provided with at least two first latches 9, the back panel of the display module is provided with a first latch groove corresponding to the first latch groove 9, and the second shell 8 is provided with a third latch groove 11 corresponding to the first latch groove 9. The first shell 1 is connected to the back panel and the second shell 8 respectively through the engagement of the first latch groove 9 with the first latch groove, and the first latch groove 9 with the third latch groove 11. When the display module is assembled, align the first shell 1 with the side terminal, i.e., the first terminal, and then slide the first shell 1 laterally. The first latch groove 9 engages with the first latch groove and the third latch groove 11, so that the first shell 1 is tightly matched with the back panel and the second shell 8. The first shell 1 and the second shell 8 can be conveniently disassembled and assembled, so that various adjustments can be made when necessary. Preferably, as Figure 3 As shown, when there are two first latch tongues 9 on the first housing 1 , the two first latch tongues 9 are centrally symmetrically arranged on the first housing 1 for the best fixing effect.

[0038] In this embodiment, a plurality of heat dissipation holes 25 are further provided on the first side wall 3. Preferably, the heat dissipation holes 25 are provided on the upper and lower sides of the first side wall 3 to form convection in the first shell 1, thereby bringing the heat generated by the circuit board 22 to the outside of the first shell 1, thereby cooling the circuit board 22.

[0039] In this embodiment, in order to further fix the first shell 1, the flat plate portion 2 of the first shell 1 is provided with a plurality of fixing posts 12 extending toward the back plate and provided with a center hole 13, and the second shell 8 is provided with at least one fixing hole 14 corresponding to the fixing post 12, and a screw is provided in the center hole 13 to be screwed to the back plate. After the first shell 1 is snapped into place by the first latch 9 and the first and third latch slots 11, it can be understood that the back plate is provided with a screw hole corresponding to the center hole 13, the center hole 13 is aligned with the screw hole, and the screw in the center hole 13 is screwed to the screw hole to complete the fixation between the first shell 1 and the back plate, and reference is made to Figure 4 , Figure 7 As shown, the second shell 8 is provided with a fixing hole 14 corresponding to the fixing column 12, which can fix the first shell 1 and the second shell 8. The above operation only requires at least three screws to stably fix the second shell 8, which greatly reduces the number of locking screws.

[0040] In an optional embodiment, a plurality of second latch tongues 15 are provided on the edge of the cover plate 6, and a second latch groove 16 corresponding to the second latch tongue 15 is provided at the edge of the opening 5 of the first shell 1, and the cover plate 6 is fixed in the opening 5 by the engagement of the second latch tongue 15 and the second latch groove 16. The first shell 1 and the cover plate 6 can be conveniently disassembled and assembled by the corresponding engagement of the second latch tongue 15 and the second latch groove 16, so that various adjustments can be made when necessary. The above-mentioned arrangement makes the assembly process quick and significantly improves the labor efficiency.

[0041] In this embodiment, in order to prevent the user from easily disassembling the cover plate 6 and avoid danger, one of the plurality of second latch tongues 15 is configured as a U-shaped elastic arm 17 that is squarely bent toward the second latch slot 16. The U-shaped elastic arm 17 can be inserted into the second latch slot 16 to achieve a hidden fit in which the U-shaped elastic arm 17 completely enters the second latch slot 16. It can only be disassembled by professional tools, taking into account the anti-disassembly design requirements and having high safety. Regarding the opening method of the cover plate 6, a 1mm thick and 4mm wide plectrum can be used to penetrate into the U-shaped gap of the U-shaped elastic arm 17 at an angle of about 45°, and the U-shaped elastic arm 17 can be pulled to pop out the cover plate 6 to open it.

[0042] Specifically, Figure 8 , Fig. 9 As shown, the cover plate 6 and the opening 5 are both set to be rectangular, the U-shaped elastic arm 17 is one and is arranged at the center of one side edge of the cover plate 6, and the second latch tongues 15 are two and are arranged on the other side edge relative to the U-shaped elastic arm 17. Usually, the circuit board with the connection terminal is rectangular, and in order to match it, the cover plate 6 and the opening 5 are both set to be rectangular; when the cover plate 6 needs to be installed, the second latch tongue 15 of the cover plate 6 can be inserted into the corresponding second latch groove 16, and then the cover plate 6 is rotated counterclockwise with the side edge that is engaged with the opening 5 as the axis, so that the U-shaped elastic arm 17 is engaged with the corresponding second latch groove 16, so that the cover plate 6 is fixed in the opening 5 to complete the assembly.

[0043] Furthermore, if Figure 8 , Fig. 9 As shown, two limit plates 18 are respectively provided on the two side edges of the cover plate 6 adjacent to the edge where the U-shaped elastic arm 17 is located, which are perpendicular to the extension direction of the cover plate 6, and a limit hole 19 corresponding to the limit plate 18 is opened on the first shell 1. The two limit plates 18 perpendicular to the extension direction of the cover plate 6 can play a role in auxiliary positioning. When they are inserted into the limit holes 19, the cover plate 6 can be limited to move up and down, ensuring that the deviation of the hole position is within the tolerance range, so that the cover plate 6 will not collide with the first shell 1 during the vibration test.

[0044] In an optional embodiment, if Figure 5 As shown, the surface of the flat plate portion 2 is recessed toward the back plate to form a second side wall 20, and the second side wall 20 encloses an opening 5. The advantage is that the second side wall 20 surrounds the position where the second terminal is located. Due to the existence of the second side wall 20, the opening 5 has a certain depth in the direction toward the back plate, which can protect the cover plate 6 and the second terminal. At the same time, when the second terminal is connected to an external wire, it can also ensure that the connection between the second terminal and the wire will not exceed the thickness of the first housing 1, that is, the connection is located on the inner side of the plane where the flat plate portion 2 is located, ensuring normal connection and preventing the connection from being affected by external forces and directly damaging the second terminal.

[0045] In addition, since the cover plate 6 is smaller than the first shell 1, when the second through hole 7 on the cover plate 6 needs to be modified, whether the hole position is incorrect and needs to be modified, or the shape of the second terminal changes and the shape of the second through hole 7 needs to be changed, the cover plate 6 is easier to implement than the first shell 1.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
