The present application relates to the technical field of antenna installation, and in particular to an antenna installation structure for a display device.

Background Art

Interactive tablets, commercial display screens, smart blackboards and other display devices are integrated with antenna modules that can send and receive wireless signals. Traditional bottom-out antenna modules are generally installed in the cavity of the frame or fixed on the back side of the frame. Since the frame of the display device is generally a metal frame and the back plate is generally a metal plate, in order to avoid signal shielding and avoid affecting the front appearance, it is necessary to open a through slot corresponding to the installation position of the antenna module on the bottom side of the frame (when the antenna module is installed in the frame) or the bottom side of the back plate (when the antenna module is fixed on the back side of the frame, covered by the back plate), and use a Mylar sheet to seal the through slot so that the antenna module can send and receive signals outward through the through slot. The antenna module can send and receive signals downward through the through slot, but wireless products such as wireless screen transmission and microphones are generally located in front of the display device (on the desk). The signal transmission and reception direction of the antenna module cannot face the wireless product directly, and the antenna has poor directivity, resulting in poor wireless signal transmission between the wireless product and the display device.

The antenna assembly is installed on the back side of the back plate, and the radiation module of the antenna assembly is aligned with the air avoidance hole, so that the antenna assembly can send and receive signals forward through the signal air avoidance area.

DETAILED DESCRIPTION

In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the objects associated before and after are in an "or" relationship.

The traditional bottom-out antenna module is generally installed in the cavity of the frame or fixed on the back side of the frame. Since the frame of the display device is generally a metal frame and the back plate is generally a metal plate, in order to avoid signal shielding and avoid affecting the front appearance, it is necessary to open a through slot corresponding to the installation position of the antenna module on the bottom side of the frame (when the antenna module is installed in the frame) or the bottom side of the back plate (when the antenna module is fixed on the back side of the frame, covered by the back plate), and use a Mylar sheet to seal the through slot so that the antenna module can send and receive signals outward through the through slot. The antenna module can send and receive signals downward through the through slot, but wireless products such as wireless screen transmission and microphones are generally located in front of the display device (on the desk). The signal transmission and reception direction of the antenna module cannot face the wireless product directly, and the antenna has poor directivity, resulting in poor wireless signal transmission between the wireless product and the display device.

In addition, since the backplane itself is relatively thin, a through slot is opened at the bottom fold of the backplane, and the through slot is close to the edge of the backplane, which can easily affect the strength of the backplane; although the through slot can be blocked by sticking a Mylar sheet, the bottom side of the display device is still a position that is easily observed by users. Since the appearance of the Mylar sheet itself is inconsistent with the backplane or frame, using the Mylar sheet to block the through slot will affect the appearance of the product. With the gradual enrichment of product functions, existing antenna boards often integrate functions such as wifi, Bluetooth, and wired networks. Placing them inside the display device requires a large layout space, which is difficult to arrange.

In order to solve the above technical problems, as shown in Figures 1-11, this embodiment provides an antenna installation structure for a display device, including a display device 1 and an antenna assembly 2, wherein the antenna assembly 2 is electrically connected to a control panel in the display device 1, and wireless signals can be sent and received through the antenna assembly 2, thereby realizing the function of wireless signal transmission between the display device 1 and other wireless devices. Among them, the display device 1 can be an interactive flat panel, a commercial display host, a smart blackboard, a display, a television and other products, and other wireless devices can be products such as routers, microphones, wireless screen transmission devices, cameras and the like. It should be noted that, with reference to Figure 2, in the description of this application, the description is based on the state of the display device 1 in normal use, that is, the display device 1 is installed vertically (such as wall-mounted, supported by a bottom bracket or suspended from a top ceiling, etc.), the display surface viewed by the user is the front side, and the side facing away from the front side is the rear side.

The display device 1 includes a frame 11, a back panel 12 and a backlight module 13. The frame 11 is connected to the back panel 12. The back panel 12 is provided with a backlight module 13 mounted on the front side of the back panel 12, a signal avoidance area 15 for front and rear wireless signals to pass through is formed between the outer edge of the backlight module 13 and the inner edge of the frame 11, and a avoidance hole 121 corresponding to the signal avoidance area 15 is provided on the back panel 12;

The antenna assembly 2 is installed on the back side of the back plate 12 , and the radiation module of the antenna assembly 2 is aligned with the air avoidance hole 121 , so that the antenna assembly 2 can send and receive signals forward through the signal air avoidance area 15 .

Specifically, the invention focus of this solution is to achieve that the antenna assembly 2 is installed on the back side of the display device 1 while the antenna assembly 2 can normally send and receive signals forward.

The display device 1 structure also includes a glass panel 14 located on the front side of the backlight module 13. Since both the frame 11 and the backlight module 13 have the performance of shielding signals, in order to allow wireless signals to be transmitted forward and backward, a signal avoidance zone 15 is formed between the frame 11 and the backlight module 13 of this solution, through which wireless signals pass forward and backward. Specifically, the formation structure of the signal avoidance zone 15 is as follows: referring to Figures 4-5, with the central axis of the display device 1 in the front-to-back direction as the reference axis, in its radial direction, there is a certain interval between the outer edge of the backlight module 13 and the inner edge of the frame 11, and the signal avoidance zone 15 is formed in the interval, so that the radiation module of the antenna assembly 2 will not be blocked or shielded by the backlight module 13 or the frame 1 in the process of forward signal transmission and reception. It should be noted that the signal avoidance area 15 in this description is the front and rear wireless signal penetration, which means that the transmission of wireless signals is not shielded, or the shielding effect is very small, and does not mean complete clearance. Even if the signal avoidance area 15 is filled with insulating materials (i.e. materials with extremely small signal shielding ability), the front and rear wireless signals of the signal avoidance area 15 can be maintained. For example, a glass panel 14 is actually provided on the inner side of the frame 11. The glass panel 14 passes through the signal avoidance area 15, but does not affect the transmission of wireless signals. The back panel 12 is made of metal material, which will shield the signal. Therefore, in order to avoid affecting the wireless transmission, the present solution opens a avoidance hole 121 on the back panel 12 at the position corresponding to the signal avoidance area 15. The radiation module on the back side of the back panel 12 can send and receive signals forward through the avoidance hole 121.

In practical applications, the antenna assembly 2 can be installed on the top, bottom, left or right of the display device 1. Preferably, the antenna assembly 2 is installed on the top of the display device 1. A main control board is installed on the back of the display device 1. The main control board is generally installed at the bottom. The antenna assembly 2 is installed on the top to keep it away from the main control board, thereby reducing the interference of the main control board to the antenna assembly 2 when it is working.

In summary, based on the antenna installation structure of the display device of this embodiment, a signal air avoidance area 15 is set between the outer edge of the backlight module 13 and the inner edge of the frame 11 in the front-to-back direction to allow the normal passage of wireless signals, and a corresponding air avoidance hole 121 is set on the back plate 12. The antenna component 2 is directly installed on the back side of the back plate 12, and the antenna component 2 can transmit and receive signals forward through the air avoidance hole 121 and the signal air avoidance area 15. Therefore, the antenna installation structure of this scheme can realize the hidden installation of the antenna component 2 while also realizing the forward transmission and reception of signals by the antenna component 2. The signal transmission and reception direction of the antenna component 2 can face the wireless product directly in front of the display device 1, which optimizes the directivity of the antenna and solves the problem of poor wireless signal transmission effect between traditional wireless products and the display device 1.

In addition, the antenna assembly 2 is directly mounted on the back side of the back plate 12, that is, in normal use, the antenna assembly 2 is placed against the wall, and it is not easy for the user to observe the existence of the antenna assembly 2, especially when the antenna assembly 2 is placed on the top of the display device 1, the user can hardly see the antenna assembly 2. Compared with the prior art that requires pasting the Mylar sheet after opening a hole at the bottom of the frame 11 or the back plate 12, this solution can keep the frame 11 and the bottom of the back plate 12 intact, so from the perspective of what the user can see, the appearance of the display device 1 of this solution is better in integrity and more beautiful. Moreover, since the antenna assembly 2 is directly mounted outside the display device 1, it does not need to occupy the space inside the display device 1, so the problem of difficult layout of the antenna assembly 2 is solved.

In one embodiment, the antenna assembly 2 includes an antenna bracket 22 and an antenna plate 21 , the radiation module is disposed on the antenna plate 21 , the antenna plate 21 is mounted on the antenna bracket 22 , and the antenna bracket 22 is mounted on the back side of the back plate 12 .

The antenna bracket 22 can be designed into any structure according to the requirements of cooperation with the display device 1 and the antenna board 21, so as to realize the reliable installation of the antenna bracket 22 on the display device 1, and realize the reliable installation of the antenna board 21 on the antenna bracket 22. Therefore, the antenna bracket 22 is provided in the present solution to support the antenna board 21, which can provide reliable support for the antenna board 21, so as to protect the antenna board 21, and at the same time improve the stability of the installation of the antenna board 21.

In one embodiment, the antenna bracket 22 is an insulator, the antenna bracket 22 is arranged to fit the back plate 12 , and the antenna plate 21 is installed on a side of the antenna bracket 22 facing away from the back plate 12 .

Specifically, the conductive properties of a material are positively correlated with its signal shielding properties, that is, the antenna bracket 22, which is an insulator, has weaker signal shielding properties. The antenna bracket 22 is set as an insulator so that the antenna plate 21 can be installed on the back side of the antenna bracket 22, and at the same time, the radiation module on the antenna plate 21 can achieve barrier-free signal reception and transmission through the antenna bracket 22, thereby ensuring its high-quality antenna performance. Based on this, the antenna bracket 22 can be installed completely in contact with the surface of the back plate 12, thereby achieving the effect of improving the reliability of the installation of the antenna bracket 22, that is, ensuring the reliability of the installation of the antenna plate 21; in addition, the antenna plate 21 is installed on the side of the antenna bracket 22 that is away from the back plate 12, which can avoid the risk of damage to the antenna plate 21 caused by squeezing the back plate 12 and the antenna bracket 22.

In one embodiment, a sealing member 221 is disposed between the antenna bracket 22 and the back plate 12 , and the air avoidance hole 121 is sealed by the sealing member 221 .

Specifically, the air avoidance hole 121 is arranged in an area outside the outer edge of the backlight module 13, that is, taking the air avoidance hole 121 arranged at the top of the back plate 12 in the figure as an example, the air avoidance hole 121 is located in the area above the backlight module 13, and the air avoidance hole 121 is actually connected to the space between the backlight module 13 and the glass panel 14. However, in the display device 1, the space between the backlight module 13 and the glass panel 14 has high requirements for air cleanliness, and dust entering the space will have a significant impact on the display effect. Therefore, in this solution, a seal 221 is arranged between the antenna bracket 22 and the back plate 12, and the air avoidance hole 121 is sealed by the seal 221, so as to prevent dust from entering the front area of the backlight module 13 through the air avoidance hole 121.

Furthermore, in order to realize the electrical connection between the antenna board 21 and the main control board in the display device 1, realize the power supply to the antenna board 21, and the signal transmission between the two, referring to FIG. 3 , a wire hole 122 is provided on the back panel 12 in the area corresponding to the back side of the backlight module 13, and the antenna board 21 is connected to a flat cable 212, which extends to the inner side of the back panel 12 through the wire hole 122 and is connected to the main control board. It should be noted that the backlight module 13 is installed on the front side of the back panel 12, and a sealing structure is arranged between its periphery and the back panel 12, so the front and rear sides of the backlight module 13 are actually two independent spaces. The front side of the backlight module 13 is the light-emitting surface, which has higher requirements for air cleanliness, and the back side does not have such high requirements. The wire hole 122 of the present solution is arranged on the back panel 12 corresponding to the area on the back side of the backlight module 13. Dust enters the back side of the backlight module 13 through the wire hole 122, and it will not affect the display effect, so there is no need to seal the wire hole 122 with high requirements.

Regarding the setting of the sealing member 221, in one embodiment, referring to Figure 11, the sealing member 221 includes a sealing boss 2211 protruding from the side of the antenna bracket 22 facing the back plate 12, and the size of the sealing boss 2211 is larger than the size of the air avoidance hole 121. The sealing boss 2211 completely abuts against the outer periphery of the air avoidance hole 121 to achieve sealing of the air avoidance hole 121.

Specifically, the size of the sealing boss 2211 is larger than the air avoidance hole 121. After installation, the front surface of the sealing boss 2211 completely abuts against the material on the back plate 12 around the air avoidance hole 121, thereby forming a seal for the air avoidance hole 121. The sealing boss 2211 is directly integrally formed during the injection molding stage of the antenna bracket 22. Compared with the front surface of the entire antenna bracket 22, the surface area of the sealing boss 2211 is smaller, which is more conducive to its close fit with the surface of the back plate 12. The area outside the sealing boss 2211 does not require the antenna bracket 22 to be closely fitted with the surface of the back plate 12. Therefore, the provision of the sealing boss 2211 can meet the need for reliable sealing of the air avoidance hole 121.

In this method, a sealing boss 2211 is integrally formed directly on the antenna bracket 22 to form a seal, which reduces the number of parts in the product and reduces the material cost. In addition, the air avoidance hole 121 is sealed while the antenna bracket 22 is installed, which simplifies the assembly process and improves production efficiency.

Optionally, referring to Figures 4 and 11, the sealing member 221 also includes a positioning boss 2212 protruding from the sealing boss 2211, the positioning boss 2212 is clearance-matched with the air avoidance hole 121, and the positioning boss 2212 is embedded in the air avoidance hole 121 to form a positioning, so that the sealing boss 2211 can completely abut the outer periphery of the air avoidance hole 121.

Specifically, the positioning boss 2212 is clearance-matched with the air avoidance hole 121, that is, the size of the positioning boss 2212 is slightly smaller than the size of the air avoidance hole 121. During installation, the positioning boss 2212 can be easily embedded in the air avoidance hole 121 to guide the accurate installation of the antenna bracket 22, so that the surface of the sealing boss 2211 can be completely and tightly fitted to the outer periphery of the air avoidance hole 121, thereby avoiding the problem of the sealing boss 2211 being misplaced and affecting the sealing performance after installation.

Regarding the setting of the sealing member 221, in another embodiment, the sealing member 221 is a sealing gasket arranged on the back side of the back plate 12, and the sealing gasket completely covers the air avoidance hole 121; or, the sealing member 221 is a sealing ring arranged around the periphery of the air avoidance hole 121. After the antenna bracket 22 is installed, the antenna bracket 22 completely presses the sealing gasket or the sealing ring to achieve sealing of the air avoidance hole 121. The sealing gasket and the sealing ring are preferably made of flexible materials with good sealing performance, such as rubber parts and silicone parts.

In one embodiment, a grounding avoidance hole 224 is provided on the antenna bracket 22 , and a conductive foam is provided on a side of the antenna plate 21 close to the antenna bracket 22 , and the conductive foam contacts the back plate 12 through the grounding avoidance hole 224 .

Referring to Figure 11, specifically, a grounding avoidance hole 224 is set in the antenna bracket 22 to avoid the conductive foam used for grounding the antenna board 21. While meeting the grounding requirement of the antenna board 21, the entire antenna board 21 can be completely installed on the antenna bracket 22, so that the antenna bracket 22 can provide protection for the periphery of the entire antenna board 21.

In one embodiment, referring to FIGS. 9-10 , a snap-fit structure is provided on the antenna bracket 22 , and the antenna board 21 is snap-fitted with the snap-fit structure to achieve installation of the antenna board 21 on the antenna bracket 22 .

The antenna plate 21 is clamped and fixed using a snap-fit structure, thereby achieving screw-free installation of the antenna plate 21. During installation, the antenna plate 21 is directly pressed into a position where it is clamped with the snap-fit structure, thereby reducing the number of parts required for product assembly and simplifying the assembly process.

In one embodiment, the snap-fit structure includes a limiting column 225 and a limiting buckle 226. A limiting hole 211 corresponding to the limiting column 225 is provided on the antenna plate 21. The limiting column 225 passes through the limiting hole 211, and the limiting buckle 226 buckles the edge of the antenna plate 21.

Specifically, the cooperation between the limiting column 225 and the limiting hole 211 can limit the movement of the antenna board 21 in the up-down direction and the left-right direction. The front side of the antenna board 21 abuts against the back side of the antenna bracket 22, and the back side is limited by the limiting buckle 226, thereby limiting the movement of the antenna board in the front-back direction. Therefore, based on the combination of the limiting column 225 and the limiting buckle 226, the antenna board 21 is completely positioned, ensuring the reliable installation of the antenna board 21.

The setting of the limiting column 225 is preferably that a limiting column 225 is respectively set on the left and right sides of the antenna bracket 22. According to the principle that two points determine a straight line, the movement of the antenna bracket 22 in the up and down directions and the left and right directions can be completely limited. The setting of the limiting buckle 226 is preferably that a limiting buckle 226 is respectively set at the four corners of the antenna bracket 22 to achieve the positioning of the four corners of the antenna board 21. While meeting the requirements of reliable fixation, using a smaller number of limiting buckles 226 can reduce the difficulty of disassembly and assembly of the antenna board 21.

In one embodiment, referring to FIGS. 4-8 , the antenna assembly 2 further includes an antenna cover 23 , which is installed on the back side of the frame 11 and covers the antenna plate 21 and the antenna bracket 22 .

The antenna cover 23 is provided to cover the antenna plate 21 and the antenna bracket 22, which can not only isolate and protect the antenna plate 21, but also prevent the antenna plate 21 and the antenna bracket 22 from being exposed, thereby optimizing the appearance of the product. Preferably, in order to hide the antenna cover 23, the antenna cover 23 does not protrude from the outer edge of the frame 11.

In one embodiment, first fixing ears 223 are respectively provided on two opposite sides of the antenna bracket 22, and second fixing ears 231 are respectively provided on two opposite sides of the antenna cover 23. The two first fixing ears 223 respectively abut against the back side of the frame 11, and the two second fixing ears 231 respectively press the two first fixing ears 223 to fix the antenna bracket 22.

That is, the antenna bracket 22 is directly pressed and fixed by installing the antenna cover 23, which can save the screws for fixing the antenna bracket 22 separately, reduce the use of fastening parts, and simplify the assembly process.

In one embodiment, a first positioning hole 2231 is provided on the first fixing ear 223 , and a first positioning column 2311 is provided on the second fixing ear 231 . The first positioning column 2311 is embedded in the first positioning hole 2231 for positioning.

The first positioning hole 2231 and the first positioning column 2311 are respectively provided on the first fixing ear 223 and the second fixing ear 231 for matching and positioning, so that the antenna bracket 22 and the antenna cover 23 can be accurately matched, and the problem of misalignment between the antenna bracket 22 and the antenna cover 23 can be avoided. In addition, based on this positioning structure, the antenna bracket 22 can be quickly and accurately fixed to the antenna cover 23 during installation, and then the two can be installed together on the display device 1, thereby improving the convenience of assembly.

In one embodiment, the frame 11 is provided with a second positioning hole 112 , the first fixing ear 223 is provided with a second positioning post 2232 , and the second positioning post 2232 is embedded in the second positioning hole 112 for positioning.

Specifically, the frame 11 has a cavity inside, and a second positioning hole 112 is provided on the frame 11, allowing the second positioning post 2232 to extend into the second positioning hole 112 to achieve reliable positioning. Based on the cooperation between the second positioning post 2232 and the second positioning hole 112, the accuracy of the installation position of the antenna bracket 22 on the display device 1 can be improved, that is, the accuracy of the installation of the antenna assembly 2 can be improved; and the rapid alignment of the antenna assembly 2 during installation can be facilitated.

In one embodiment, a first connecting hole 2312 is provided on the second fixing ear 231 , and a second connecting hole 113 is correspondingly provided on the frame 11 . A connecting pin 24 passes through the first connecting hole 2312 and the second connecting hole 113 to fix the antenna cover 23 to the back side of the frame 11 .

The connecting pin 24 may be a screw or a rivet, and is preferably a screw, which can realize the detachable installation of the antenna assembly 2; preferably, the second connecting hole 113 is a threaded hole, and the connecting pin 24 can be directly threadedly connected to the second connecting hole 113. The second connecting hole 113 is arranged on the frame 11, and the material thickness and strength of the frame 11 are greater than those of the back plate 12, which can improve the reliability of the connection between the connecting pin 24 and the second connecting hole 113, that is, the reliability of the installation of the antenna assembly 2 is improved.

In one embodiment, a reinforcing boss 222 is disposed on a side of the antenna bracket 22 close to the frame 11 , and an avoidance groove 111 corresponding to the reinforcing boss 222 is disposed on the frame 11 .

Specifically, the reinforcing boss 222 extends along the length direction of the antenna bracket 22, which can improve the strength of the antenna bracket 22, enhance the bending resistance, and avoid deformation. The avoidance groove 111 is provided on the frame 11, so that the reinforcing boss 222 can be provided on the side of the antenna bracket 22 close to the frame 11, avoiding the problem that the setting of the reinforcing boss 222 hinders the installation of the antenna board 21.
