With the development of technology, more and more display devices are used in teaching and conference rooms, such as electronic whiteboards and LCD screens. In the application process of the display device, the display device is generally configured with an antenna, such as a wifi2.4g antenna, a wifi5.0g antenna, a bluetooth antenna, and the like.

In the related art, as shown in fig. 1, the antenna 3 configured by a part of the display device 10 is a rod antenna, and the rod antenna is fixed outside the housing 11 of the display device 10, so that the signal strength of the antenna 3 is ensured, but the rod antenna has a certain length, which not only affects the overall appearance of the display device 10, but also is unfavorable for popularization of the display device 10, such as popularization in scenes used by walls in teaching, conference rooms, and the like.

In addition, some of the antennas 3 disposed in the display device 10 are patch antennas, however, the patch antennas are disposed in the housing 11 of the display device 10, so that the aesthetic property of the display device 10 is ensured, but the housing 11 has a large number of metal structural members, and the housing 11 itself is shielded, so that the radiation effect of the patch antennas is as shown in fig. 2, and the signal intensity of the patch antennas is weak and the transmission rate is poor.

The disclosed embodiments provide a display device 10. As shown in fig. 3 or 4, the display device 10 includes a display body 1 and a carrier 2, where the display body 1 includes a housing 11 and a control main board (not shown in the drawings) located in the housing 11, and the carrier 2 is fixedly connected to the housing 11.

The display device 10 may be an electronic whiteboard such as a teaching whiteboard, a multimedia display screen, or the like. The housing 11 includes a back plate and a frame, and the carrier 2 may be fixed on the back plate or the frame, which may be specifically determined according to a carrying manner of the carrier 2 on the housing 11.

In some embodiments, the display device 10 is usually supported on a carrier such as a cabinet, and in order to improve stability of the display device 10 when placed, as shown in fig. 3, a bracket 22 is usually disposed on the display device 10 (where the bracket 22 is fixedly connected to the frame (e.g. fixed to the bottom of the frame or fixed to the side of the frame)), that is, the carrier 2 is the bracket 22. In this way, the support of the display device 10 on the carrier can be realized through the arrangement of the support 22, so that the stability of the display device 10 is improved.

In some embodiments, for the large-sized display device 10, in order to facilitate moving or carrying, as shown in fig. 4, a handle 23 (the handle 23 is fixed on the back plate or fixed on the side of the frame) is generally disposed on the display device 10, that is, the carrier 2 is the handle 23. Thus, the movement or transportation of the display device 10 can be realized by the handle 23, thereby improving the movement or transportation efficiency of the display device 10.

In the embodiment of the disclosure, as shown in fig. 5, the carrier 2 has a receiving cavity (not shown in the drawing), and a cavity wall of the receiving cavity has a notch 21 passing therethrough, and/or a material of at least part of the cavity wall of the receiving cavity is non-metal, and the display device 10 includes an antenna 3, and at least part of the antenna 3 is located in the receiving cavity and coupled with the control motherboard.

Thus, by arranging the accommodating cavity on the bearing piece 2, the installation space of the antenna 3 is provided, and the attractiveness of the display device 10 is ensured; in addition, the antenna 3 is arranged in the accommodating cavity of the bearing piece 2, so that the number of the antennas 3 arranged in the shell 11 of the display body 1 can be reduced, and the space occupied by the antennas 3 in the shell 11 is saved; in the working process of the antenna 3, the cavity wall of the accommodating cavity is provided with the through notch 21, and/or the material of at least part of the cavity wall of the accommodating cavity is nonmetal, so that shielding of the antenna 3 is avoided, and the radiation effect of the antenna 3 is shown in fig. 6. As can be seen from a comparison of fig. 2 and fig. 6, the antenna 3 of the display device 10 according to the embodiment of the present disclosure has a better radiation effect.

The manner in which the antenna 3 is arranged will be explained in detail in connection with the specific structure of the carrier 2.

As shown in fig. 3, the carrier 2 is a bracket 22, and the bracket 22 is fixed to the bottom of the housing 11 to support the housing 11.

Wherein the holder 22 has a receiving cavity (not shown in the figures) so that the antenna 3 is arranged in the receiving cavity on the holder 22. Optionally, the opening of the accommodating cavity faces the housing 11, and the feeder line 12 connected with the antenna 3 can extend along the opening of the accommodating cavity and then extend into the housing 11 to be coupled with the control main board; or as shown in fig. 3 and 7, the opening of the accommodating cavity faces away from the housing 11, and the bracket 22 further has a first through hole 222 that communicates with the accommodating cavity and penetrates the bracket 22, where the first through hole 222 is used for penetrating the coupling antenna 3 and the feeder 12 of the control motherboard. In this way, the feeder line 12 connected with the antenna 3 passes through the first through hole 222 and then stretches into the shell 11 to be coupled with the control main board, so that the reliability of the arrangement of the antenna 3 is ensured.

Wherein, the shell wall of the shell 11 has an opening that is directly communicated with the accommodating cavity, or is communicated with the accommodating cavity through the first through hole 222, so that the feeder line 12 extends out of the accommodating cavity, or extends into the shell 11 along the opening after passing through the first through hole 222.

Alternatively, as shown in fig. 7, the bracket 22 has a first accommodating groove 221, and the groove wall of the first accommodating groove 221 encloses an accommodating cavity. In this way, by arranging the first accommodating groove 221 on the bracket 22, the antenna 3 is conveniently arranged in the first accommodating groove 221, so that the arrangement efficiency of the antenna 3 is improved.

Of course, the support 22 may be provided with a through hole, and the wall of the through hole may further define a receiving cavity, which is not limited in the embodiment of the present application.

It should be noted that, in the case that the bracket 22 has the first accommodating groove 221, as can be seen from fig. 3 and 7, the first accommodating groove 221 may be located at a side of the bracket 22 away from the display body 1, so as to further realize hiding of the antenna 3 in the first accommodating groove 221; of course, the first receiving groove 221 may be located at a side of the stand 22 facing the display body 1. When the first accommodating groove 221 is positioned on one side of the bracket 22 facing the display body 1, the bracket 22 is provided with a baffle plate for shielding the notch of the first accommodating groove 221, so that the hiding of the antenna 3 is realized, and the aesthetic property is improved; meanwhile, the protection of the antenna 3 is realized, and the service life of the antenna 3 is prolonged.

As shown in fig. 4 or 5, the carrier 2 is a pull 23.

As shown in fig. 5, the pull handle 23 includes: the handrail 231 and the fixed otic placode 232 that is located the at least one end of handrail 231, fixed otic placode 232 and casing 11 fixed connection.

The armrests 231 and the fixed lugs 232 are in linear structures, and the fixed lugs 232 are connected with the handles 23 at right angles; alternatively, as shown in fig. 5, the armrest 231 has a linear structure, the end of the fixed ear 232 has a circular arc transition region, and one end of the fixed ear 232 near the circular arc transition region is connected to the armrest 231.

As shown in fig. 5, the handle 23 includes two fixing lugs 232, and the two fixing lugs 232 are respectively fixedly connected with the armrest 231 at two ends of the armrest 231, or the two fixing lugs 232 and the armrest 231 are in an integrated structure. Of course, the handle 23 may also include only one fixed ear plate 232, which is not limited in the embodiment of the present disclosure.

Wherein, the fixing lug 232 has a fixing hole so that the fixing lug 232 is fixedly connected with the housing 11 by a fixing member passing through the fixing hole, thereby fixing the handle 23 on the housing 11 of the display device 10. The fixing member may be a fixing bolt, but may be other fixing members, which is not limited in the embodiment of the present disclosure.

In the embodiment of the present disclosure, when the holding cavity is formed in the handle 23, the holding cavity may be formed in the armrest 231, or the holding cavity may be formed in the fixed ear plate 232, or of course, the holding cavities may be formed in both the armrest 231 and the fixed ear plate 232.

In some embodiments, as shown in fig. 5, the armrest 231 has a recess 2313, and the cavity of the recess 2313 forms a receiving cavity. As such, the antenna 3 may be disposed within the recess 2313 to enable installation of the antenna 3.

The notch of the groove 2313 forms a notch 21 to avoid shielding the radiation signal of the antenna 3 in the groove 2313 and improve the radiation performance of the antenna 3.

Wherein, the armrest 231 may be a solid structure to facilitate the placement of the groove 2313; of course, the handrail 231 may be a hollow structure, as long as the handrail 231 has a certain wall thickness, and the arrangement of the grooves 2313 is not affected. The shape of the groove 2313 may be designed according to the shape of the antenna 3. For example, for a rod antenna, the groove 2313 may be a bar-shaped groove; for a patch antenna, the groove 2313 may be a rectangular slot.

Wherein the groove 2313 may extend along a length direction of the armrest 231 so that a plurality of antennas 3 are installed in the groove 2313 along the groove 2313. And when the number of the antennas 3 installed in the groove 2313 is greater, the number of the antennas 3 provided in the display body 1 itself is smaller, thereby improving the radiation effect of the antennas 3 of the display device 10 as a whole.

A plurality of antennas 3 may be arranged along the extending direction of the groove 2313, and the antennas 3 may be installed at the bottom of the groove 2313. Of course, the antenna 3 may be mounted on the wall of the groove 2313 along the extending direction as long as the radiation performance of the antenna 3 is not affected, which is not limited by the embodiment of the present disclosure.

Optionally, the handle 23 further includes a cover plate, which is in limiting connection with the armrest 231 and can block the notch of the groove 2313. Thus, the hiding of the antenna 3 can be realized through the arrangement of the cover plate, and the aesthetic property is improved; meanwhile, the protection of the antenna 3 is realized, and the service life of the antenna 3 is prolonged.

The cover plate is made of a non-metal material, so that the radiation performance of the antenna 3 in the groove 2313 can be guaranteed. Further, the armrests 231 are also made of non-metallic materials to further improve the omnidirectional radiation performance of the antenna 3.

In other embodiments, as shown in fig. 8, the armrest 231 includes a base 2311 and an upper cover 2312, the base 2311 and the upper cover 2312 are detachably fastened, and the base 2311 and the upper cover 2312 are fastened to form a containing cavity.

The manner in which the base 2311 and the upper cover 2312 are fastened may refer to the related art, which is not limited in the present disclosure. For example, the base 2311 has a barb, the upper cover 2312 has a limiting groove, and the barb of the base 2311 is detachably limited in the limiting groove to realize the buckling of the base 2311 and the upper cover 2312; or the base 2311 is fixed with a buckle, and the upper cover 2312 is fixed with a hook, so that the buckling is realized through the matching of the hook and the buckle.

Wherein, a second accommodating groove 2314 is formed on a side of the base 2311 facing the upper cover 2312, and an accommodating cavity is defined by a groove wall of the second accommodating groove 2314 and a surface of the upper cover 2312; the side of the upper cover 2312 facing the base 2311 may have a second accommodating groove 2314, where the groove wall of the second accommodating groove 2314 and the surface of the base 2311 enclose an accommodating cavity. Of course, as shown in fig. 8, the side of the base 2311 facing the upper cover 2312 and the side of the upper cover 2312 facing the base 2311 may be provided with the second accommodating grooves 2314, so that the groove walls of the two second accommodating grooves 2314 can form a accommodating cavity with a larger space after the upper cover 2312 is buckled with the base 2311. The bottom surface of the second accommodating groove 2314 may be a plane or an arc surface.

In the case that the base 2311 and the upper cover 2312 have the second accommodating groove 2314, the cavity space of the accommodating cavity can be increased, so that the arrangement of the plurality of antennas 3 is facilitated, the number of the antennas 3 required to be arranged on the display body 1 is effectively reduced, and even the antennas 3 required to be configured by the display device 10 are all arranged in the accommodating cavity of the armrest 231, so that the performance of the antennas 3 of the display device 10 is improved maximally.

When the antenna 3 is disposed in the accommodating cavity defined by the walls of the second accommodating groove 2314, a plurality of antennas 3 may be disposed according to the size of the cavity space of the accommodating cavity. In order to reduce mutual interference between the plurality of antennas 3, the receiving chamber may extend along the length direction of the armrest 231. As shown in fig. 8, for example, two antennas 3 are distributed along the extending direction of the accommodating chamber.

Of course, in combination with the above-mentioned case that the base 2311 and the upper cover 2312 have the second accommodating groove 2314, at least one antenna 3 may be disposed in the second accommodating groove 2314 of the base 2311 along the extending direction, and at least one antenna 3 may be disposed in the second accommodating groove 2314 of the upper cover 2312 along the extending direction, so as to implement the arrangement of a plurality of antennas 3. Of course, the plurality of antennas 3 may be arranged in other ways, which is not limited by the present disclosure implementation.

Wherein, the material of at least one of the base 2311 and the upper cover 2312 is non-metal. For example, the base 2311 and the upper cover 2312 are both made of non-metal, that is, the armrest 231 is made of non-metal material, so that the omnidirectional radiation performance of the antenna 3 in the accommodating cavity can be further ensured. Of course, it is also possible that one of the base 2311 and the upper cover 2312 has a notch 21 penetrating into the accommodating cavity, so that shielding of the antenna 3 is avoided by the notch 21, thereby ensuring radiation performance of the antenna 3.

In combination with the above-mentioned case that the armrest 231 includes the base 2311 and the upper cover 2312, the fixed ear plate 232 is connected to the end of the base 2311 and is designed as an integral unit with the base 2311, or the fixed ear plate 232 is connected to the end of the upper cover 2312 and is designed as an integral unit with the upper cover 2312, or as shown in fig. 8, the fixed ear plate 232 includes a first sub-ear plate 2321 and a second sub-ear plate 2322, the first sub-ear plate 2321 is connected to the end of the base 2311 and is designed as an integral unit with the base 2311, and the second sub-ear plate 2322 is connected to the end of the upper cover 2312 and is designed as an integral unit with the upper cover 2312.

In the case where the fixed ear plate 232 includes the first sub-ear plate 2321 and the second sub-ear plate 2322, the fastening between the base 2311 and the upper cover 2312 may be achieved by the fixing member while the first sub-ear plate 2321 and the second sub-ear plate 2322 are crimped. For example, the first sub-ear plate 2321 and the second sub-ear plate 2322 have sub-fixing holes with center lines coincident, and the fixing piece can sequentially pass through the sub-fixing holes on the second sub-ear plate 2322 and the sub-fixing holes on the first sub-ear plate 2321 to be fixedly connected with the shell 11 of the display body 1, and at this time, the fixing piece can be pressed on the second sub-ear plate 2322 to realize the press connection of the first sub-ear plate 2321 and the second sub-ear plate 2322.

In still other embodiments, as shown in fig. 9 and 10, the fixed ear plate 232 has a second through hole 2323, and a wall of the second through hole 2323 encloses the accommodating cavity.

The second through hole 2323 may be an equal-diameter hole or a step hole; when the second through hole 2323 is a constant diameter hole, a part of the antenna 3 is located in the second through hole 2323, and of course, all of the antenna 3 may be located in the second through hole 2323; when the second through hole 2323 is a stepped hole, the antenna 3 is located in the second through hole 2323 and is limited on the stepped surface of the second through hole 2323.

The material of the fixed ear plate 232 is a non-metal material, and/or the hole wall of the second through hole 2323 has a notch 21, so that shielding of the antenna 3 is avoided, and radiation performance of the antenna 3 is ensured. For example, when the second through-hole 2323 is a stepped hole, as shown in fig. 9 or 10, a hole wall of the end of the second through-hole 2323 with a larger hole diameter has a notch 21.

The second through hole 2323 may be reused as a fixing hole for fixing the handle 23, and the fixing member passes through the second through hole 2323 and is fixedly connected with the housing 11 of the display body 1. In addition, in the embodiment of the present disclosure, the accommodating chamber may be formed on the handle 23 by any one of the above three embodiments; of course, in the case where the armrest 231 includes the base 2311 and the upper cover 2312, and the base 2311 and the upper cover 2312 have a certain wall thickness, the recess 2313 may be formed on the base 2311 and/or the upper cover 2312 by the first embodiment described above to form the receiving cavity, which is not limited in the embodiment of the present disclosure.

At least two of the above three embodiments may be combined, and a plurality of receiving chambers may be formed in the handle 23, which is not limited in the embodiment of the present disclosure. Illustratively, the armrest 231 has one receiving cavity defined by the base 2311 and the upper cover 2312, and the fixed ear plate 232 has one receiving cavity defined by the wall of the second through hole 2323 to form two receiving cavities on the handle 23.

In the embodiment of the present disclosure, the antenna 3 may be a patch antenna or a rod antenna, and when the display device 10 includes a plurality of antennas 3, the plurality of antennas 3 may include a patch antenna or a rod antenna; of course, all patch antennas or all rod antennas may be used. For specific structures of the patch antenna and the rod antenna, reference may be made to the related art, and the embodiments of the present disclosure are not limited thereto. The patch antenna may be, for example, an FPC antenna 3.

In the above-described manner of forming the accommodating cavity, if the antenna 3 is a patch antenna, it may be fixed in the first accommodating groove 221 of the bracket 22, in the groove 2313 of the armrest 231, in the second accommodating groove 2314 of the base 2311 and/or the upper cover 2312, and in the hole wall of the second through hole 2323 of the ear plate by means of bonding. And in combination with the structures of the first receiving groove 221, the groove 2313, the second receiving groove 2314 and the second through hole 2323, the patch antenna has a certain flexibility so as to increase the bonding area when the patch antenna is fixed. Of course, the patch antenna may be fixed in other manners, which are not limited by the embodiments of the present disclosure.

If the antenna 3 is a rod antenna, it may be screwed into the first receiving groove 221 of the bracket 22, fixed into the groove 2313 of the armrest 231, fixed into the second receiving groove 2314 of the base 2311 and/or the upper cover 2312, and fixed to the wall of the second through hole 2323 of the ear plate. Of course, the rod antenna may be fixed by other means, which is not limited by the embodiments of the present disclosure.

In this embodiment of the disclosure, as shown in fig. 7 or 8, the display device 10 further includes a feeder 12, one end of the feeder 12 is coupled to the antenna 3, and the other end of the feeder 12 extends out of the accommodating cavity and then extends into the housing 11 of the display device 10 to be coupled to the control motherboard.

For the case where the accommodating chamber is formed on the handle 23, in some embodiments, the armrest 231 is formed with the accommodating chamber, and at this time, as shown in fig. 8, the accommodating chamber extends to the end of the armrest 231 to which the fixed ear plate 232 is connected, the fixed ear plate 232 has a threading hole 2324 that communicates with the accommodating chamber and penetrates the fixed ear plate 232, and the threading hole 2324 is threaded with the coupling antenna 3 and the feeder 12 of the control main board. Thus, the other end of the feeder line 12 can extend out of the accommodating cavity along the threading hole 2324 and then extend into the housing 11 to be connected with the control main board. In other embodiments, the fixed ear 232 is connected to the end of the upper cover 2312, and the base 2311 has a second accommodating groove 2314, where the base 2311 has a threading hole 2324 penetrating into the second accommodating groove 2314 or at least one end of the second accommodating groove 2314 extends to the end of the base 2311, so that the other end of the feeder 12 may extend into the housing 11 to connect with the control motherboard along the threading hole 2324 or extend out of the second accommodating groove 2314 along the opening end of the second accommodating groove 2314. In still other embodiments, the first sub-ear 2321 is connected to the end of the base 2311, the second sub-ear 2322 is connected to the end of the upper cover 2312, at least one end of the second accommodating groove 2314 extends to the end of the base 2311 or the upper cover 2312, and the first sub-ear 2321 has a threading hole 2324, so that the other end of the feeder 12 may extend into the housing 11 to connect with the control motherboard after extending out of the second accommodating groove 2314 along the opening end of the second accommodating groove 2314 and the threading hole 2324. Of course, the other end of the feeder line 12 may protrude from the accommodating chamber with reference to other embodiments, which are not limited by the disclosed embodiments.

In combination with the above-mentioned case that the second through hole 2323 on the fixed ear plate 232 encloses into a receiving cavity, and the antenna 3 is a rod antenna, the rod antenna has a fixed end, and the fixed end of the rod antenna passes through the second through hole 2323 and is coupled with the control motherboard.

The fixed end of the rod antenna is also fixedly connected with the shell 11 of the display body 1. In this way, the rod antenna can be reused as a fixture, and not only has the performance of the antenna 3 itself, but also can be used to fix the handle 23 to the housing 11 of the display body 1.

Wherein, the rod antenna has a step surface facing the fixed end, and when the second through hole 2323 is an equal diameter hole, the step surface of the rod antenna is used to be pressed against the surface of the fixed ear plate 232 so as to fix the handle 23 on the housing 11; when the second through hole 2323 is a stepped hole, the stepped surface of the rod antenna is used to press against the stepped surface of the stepped hole (i.e., the stepped surface of the rod antenna abuts against the stepped surface of the stepped hole) so as to fix the handle 23 on the housing 11.

In combination with the above-mentioned case that the second through hole 2323 on the fixed ear plate 232 encloses into a receiving cavity, and the antenna 3 is a patch antenna, the patch antenna may be curled into a cylindrical structure, and the hole wall of the second through hole 2323 is attached. The aperture of the second through hole 2323 is slightly larger than the outer diameter of the fixing member, so that a containing gap is formed between the hole wall of the second through hole 2323 and the outer wall of the fixing member, thereby facilitating placement of the patch antenna. In addition, in order to avoid the influence of the fixing piece on the radiation performance of the patch antenna, the fixing piece can be made of a nonmetallic material. Illustratively, the material of the fixing member is resin or the like.
