All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

As known from the background art, the existing installation mode of the antenna module in the interactive flat plate generally needs to be matched with a fixed structure such as an external bracket, so that the antenna module is supported and installed in the equipment frame, and the antenna module needs to adopt an antenna circuit board to provide an antenna signal receiving and transmitting function for the antenna module, so that the overall size of the antenna module is large, the equipment frame needs to provide enough installation space for the equipment frame, and the application of a narrow frame product is not facilitated. For this purpose, the present embodiment provides the following.

The present embodiment provides a frame antenna structure, and it should be noted that, in addition to being applicable to an interactive tablet, the frame antenna structure provided in the present embodiment may also be applied to other electronic devices, where the electronic devices described in the present embodiment are generally devices that function by applying electronic technology (including software) so as to implement a man-machine interaction function to a certain extent, and include, but are not limited to, electronic computers, robots, display terminals, and the like.

Referring to fig. 8, the frame antenna structure of the present embodiment includes a radiation frame 10, wherein the radiation frame 10 may use metal with higher conductivity as its production material, such as aluminum, stainless steel, iron, etc., so that the radiation frame 10 may function as a radiator in the application of the interactive flat panel, for example, may transmit and receive antenna signals.

Illustratively, the radiation frame 10 may be a profile frame or a sheet metal frame, and from the cross-sectional structure of the profile frame and the sheet metal frame, the cross section of the profile frame is generally a closed frame body structure, which is mainly formed by adopting an extrusion molding process. And one side of the sheet metal frame is generally of an open structure, and is mainly formed by bending, rolling, stamping and other processes. Taking the radiation frame 10 as a section bar for example, the radiation frame 10 is of a middle-through structure, so that an accommodating space 11 for accommodating each functional module is formed in the radiation frame 10, a through hole 12 for communicating the accommodating space 11 with the external environment is arranged on the front side of the radiation frame 10 (i.e. in the direction indicated by the arrow in the drawing), the specific structure of the through hole 12 and the specific position of the through hole on the front side of the radiation frame 10 can be determined according to the requirements of the interaction panel and the applied electronic equipment, and in general, the through hole 12 is generally arranged on the area where the antenna is arranged, which is not particularly limited in this embodiment. A mounting hole 13 for communicating the accommodating space 11 with the external environment is provided through the rear side of the radiation frame 10 (i.e. the direction of the arrow in the drawing), and the mounting hole 13 is used for providing a space for avoiding the assembly of each functional module in the interaction panel into the accommodating space 11.

As shown in fig. 1 to fig. 6, for the understanding of the present solution, in the application state of the interactive flat panel, the direction of the side of the display module 50 for providing the image display is the front side of each component, that is, the direction of the arrow in the drawing, and the side of the display module 50 away from the front side is the rear side of each component, that is, the direction of the arrow in the drawing. The left direction indicated by the arrow in the drawing and the right direction indicated by the arrow in the drawing are understood as the left and right sides of the interactive tablet in the front view direction. And the "up" direction indicated by the arrow in the drawing, and the "down" direction indicated by the arrow in the drawing, can be understood as the upper and lower sides of the interactive tablet in the front view direction.

In an example, the radiation frame 10 of the present embodiment is an aluminum profile, and since an insulating oxide layer is formed on the surface of the radiation frame 10 during the processing of the aluminum profile, in order to enable the radiation frame 10 to function as a radiator, the insulating oxide layer may be removed on the radiation frame 10 by grinding, milling, laser etching, or the like, so that the portion of the radiation frame 10 from which the insulating oxide layer is removed may be electrically connected with an external functional module.

It should be noted that, the through hole 12 and the mounting hole 13 in the present embodiment are not limited to being respectively formed on the front and rear sides of the radiation frame 10, and in fact, the through hole 12 and the mounting hole 13 may be respectively formed on any two sides of the radiation frame 10, which may be specifically determined according to the corresponding functional module structure and the specific structure of the radiation frame 10, so as to facilitate the installation of the functional module.

In addition, the through hole 12 of the present embodiment may be formed on the side portions of the lower side, the rear side, and both ends of the radiation frame 10, in addition to the front side of the radiation frame 10, as described above, but in comparison with the case where the through hole 12 is formed on the side portion other than the front side of the radiation frame 10, the through hole 12 is formed on the front side of the radiation frame 10, so that the signal transmission/reception direction can be made closer to the front side of the radiation frame 10, and the antenna signal transmission/reception direction can be made to be perpendicular to the display module 50, so that the antenna signal transmission/reception direction is oriented to the corresponding signal source, and the sensitivity of controlling the interactive device can be improved.

The above embodiment is connected, the antenna fixing structure further includes an antenna board 20, the antenna board 20 is at least partially disposed in the accommodating space 11 through the mounting hole 13, the embodiment adopts the mounting mode that the radiation frame 10 supports and fixes the antenna board 20, wherein the radiation frame 10 is formed with a mounting portion 14 on a side portion of the mounting hole 13, the mounting portion 14 is structurally configured to be in a structural form matched with the antenna board 20, so that after the antenna board 20 and the radiation frame 10 are disposed in place, the antenna board 20 can be in limit fit with the mounting portion 14, and the antenna board 20 is limited to move along the first horizontal direction.

With continued reference to fig. 6-8, in this embodiment, the through hole 12 and the mounting hole 13 are respectively formed on the front and rear sides of the radiation frame 10, and the through hole 12 and the mounting hole 13 are disposed opposite to each other, so that the antenna board 20 can continue to move in a direction close to the through hole 12 after being placed in the accommodating space 11 through the mounting hole 13 along the second horizontal direction, and finally form a matching relationship with the radiation frame 10 at the periphery of the through hole 12, that is, the mounting hole 13 has an effect of limiting the mounting and dismounting direction of the antenna board 20 to a certain extent.

As will be appreciated from the above description, the mounting portion 14 does not completely limit the relative movement between the antenna board 20 and the radiating bezel 10, and in the case where the mounting portion 14 is in a mating relationship with the antenna board 20, the mounting portion 14 is capable of limiting the movement of the antenna board 20 in a first horizontal direction while providing freedom of movement of the antenna board 20 in a second horizontal direction. In this example, the second horizontal direction is parallel to the front-back direction of the radiation frame 10, that is, under the limitation of the mounting portion 14, the antenna board card 20 can be detached from the radiation frame 10 along the front-back direction, and the first horizontal direction, that is, the direction of the radiation frame 10, may also be understood as an interactive flat plate, or the width direction (left-right direction) of the radiation frame 10, and the mounting portion 14 limits the antenna board card 20 in the second horizontal direction, so that after the antenna board card is assembled in place, the relative position of the antenna board card 20 and the through hole 12 in the width direction is unchanged, so that a stable matching relationship is formed between the feeding point on the antenna board card 20 and the portion of the radiation frame 10 located at the periphery of the through hole 12.

By implementing the above, the radiation frame 10 directly supports and fixes the antenna board card 20, and the installation mode of adopting an external bracket in the installation mode of the traditional antenna module is abandoned, so that the size of the accommodating space 11 required to be provided by the radiation frame 10 is saved, the whole structure is reduced, the compactness of the frame antenna structure is improved, and the application of narrow frame products is facilitated.

As a further embodiment, an antenna circuit is disposed on the antenna board 20, and a first feeding point 21 and a second feeding point 22 electrically connected to the antenna circuit are disposed on the antenna board 20 at intervals, and the antenna board 20 is electrically contacted with the radiation bezel 10 through the first feeding point 21 and the second feeding point 22.

With continued reference to fig. 6 and fig. 9-10, the first feeding point 21 and the second feeding point 22 are respectively located at two sides of the through hole 12, so that the first feeding point 21 and the second feeding point 22 respectively form electrical contact with the position of the radiation frame 10, so that the antenna circuit is conducted with the radiation frame 10 to form a loop, thereby realizing the function of receiving and transmitting antenna signals through the radiation frame 10.

As shown in fig. 11, for ease of understanding, the through hole 12 of the present embodiment separates the radiation frame 10 into a first side portion and a second side portion that are respectively located on opposite sides of the through hole 12, that is, the first side portion and the second side portion are actually solid structures on the radiation frame 10, so that the first side portion of the through hole 12 and the second side portion of the through hole 12 described later herein are understood as solid portions of the radiation frame 10 that are respectively located on opposite sides of the through hole 12.

The first feeding point 21 is electrically contacted with the first side of the radiation frame 10, and the second feeding point 22 is electrically contacted with the second side of the radiation frame 10, so that the antenna circuit and the radiation frame 10 are looped around the periphery of the through hole 12 to form a loop, thereby realizing the function of the antenna frame.

Here, the antenna board 20 of the present embodiment includes, but is not limited to, a WIFI module, a bluetooth module, and a network module. The frame antenna structure utilizes the radiation frame 10 as a radiator for receiving and transmitting antenna signals, the antenna board card 20 is directly matched with the radiation frame 10, the limitation of a mounting bracket and an antenna radiation module in the traditional scheme is avoided, the radiation frame 10 can save the mounting space reserved for an antenna signal receiving and transmitting circuit board in the traditional scheme, the layout of the functional module in the interactive panel is facilitated, the size of the radiation frame 10 is reduced, and the application of a narrow frame product is facilitated. In the application of the interactive flat panel, the radiation frame 10 with the reduced design occupies smaller area in the whole visual sense of the product, so that the attractive degree of the interactive flat panel is improved, and the use experience of a user is effectively improved. In addition, compared with the traditional scheme, the radiation frame 10 is larger in size, so that a better radiation effect can be obtained, and the antenna performance is improved.

In an example, please continue to refer to fig. 4 and 8, the mounting portion 14 of the present embodiment is a slot body formed along the hole edge of the mounting hole 13, and the specific opening position of the mounting portion 14 on the mounting hole 13 depends on the form of the antenna board card 20 assembled in the accommodating space 11. For example, when the antenna board 20 is required to be vertically matched with the radiation frame 10, the mounting portion 14 may be formed at the upper side and/or the lower side edge of the mounting hole 13. When the antenna board 20 is matched with the radiation frame 10 along the horizontal direction (parallel to the radiation frame 10), the mounting portion 14 may be opened at the left side and/or the right side edge of the mounting hole 13. It should be understood that the slot width of the mounting portion 14 needs to be set to a size adapted to the thickness of the antenna board 20, so that the side edges of the antenna board 20 can form a movable plug-in fit relationship with the mounting portion 14, so that the slot walls on both sides of the mounting portion 14 can guide the mounting and dismounting directions of the antenna board 20, and meanwhile, the movement of the antenna board 20 in the first horizontal direction can be limited, and the movement of the antenna board 20 in the vertical horizontal direction is also limited to a certain extent.

In order to further limit the freedom of movement of the antenna board 20 on the radiation frame 10, so that the antenna board 20 can be stably matched with the radiation frame 10, the mounting structure between the radiation frame 10 and the antenna board 20 is further optimized in this embodiment. With continued reference to fig. 3-4 and 8, the radiation frame 10 is further provided with a first fixing portion 15, where the first fixing portion 15 is located adjacent to the mounting hole 13 or the mounting portion 14, and a fixing member 16 is disposed on the first fixing portion 15, and the first fixing portion 15 and the fixing member 16 are detachably connected to each other, so that the fixing member 16 can be detachably connected to the radiation frame 10 through the first fixing portion 15. The fixing piece 16 is used for limiting the movement of the antenna board card 20 in the second horizontal direction, so that the antenna board card 20 cannot move towards the rear side direction of the radiation frame 10 in the state of being mounted on the radiation frame 10, it is to be noted that the second horizontal direction comprises the front side direction of the radiation frame 10 and the rear side direction of the radiation frame 10, and on the basis that the fixing piece 16 limits the movement of the antenna board card 20 towards the rear side direction of the radiation frame 10, the front side of the antenna board card 20 can form limit fit with the radiation frame 10, so that the movement freedom degree of the antenna board card 20 towards the front side direction of the antenna board card is limited through the radiation frame 10.

In order to enable the fixing member 16 to achieve the above effect, in a state of being mounted on the first fixing portion 15, the fixing member 16 is at least partially blocked at a side (a rear side of the radiation frame 10) of the mounting portion 14 and/or the mounting hole 13 away from the through hole 12, and the fixing member 16 may be illustratively abutted against the antenna board 20, so that the first feeding point 21 and the second feeding point 22 on the antenna board 20 can both maintain a matching relationship in electrical contact with the radiation frame 10, thereby ensuring a stable electrical connection relationship between the antenna board 20 and the radiation frame 10. Of course, in other embodiments, a certain gap may be formed between the fixing member 16 and the antenna board card 20, so as to prevent the antenna board card 20 from being separated from the radiation frame 10 along the second horizontal direction through the mounting hole 13.

Illustratively, the antenna board 20 provided in this embodiment is configured to form a step structure at a position for mating with the mounting portion 14, and as shown in fig. 9, the step structure forms a limiting portion 27 along a protruding portion of the board of the antenna board 20, where the limiting portion 27 can form a plugging mating relationship with the mounting portion 14, and also can provide a position where the fixing member 16 abuts when the antenna board 20 is plugged into the mounting portion 14.

As a specific implementation manner in the above-mentioned scheme, the first fixing portion 15 in this embodiment is a fixing hole formed on the radiation frame 10, and exemplary structural forms of the fixing hole may be a threaded hole, a unthreaded hole, etc., where the fixing hole is a threaded hole, the fixing member 16 may be a screw structure adapted to the fixing hole, and where the fixing hole is a unthreaded hole, the fixing member 16 may be an insert structure such as a bolt adapted to the fixing hole, and the two may be relatively fixed by interference fit. Of course, the fitting method of the first fixing portion 15 and the fixing member 16 is not limited to this, and the two may be connected by a connecting method capable of achieving the mutually fixed fitting.

In order to achieve the purpose that the fixing member 16 is at least partially blocked at the rear side of the mounting portion 14 and/or the mounting hole 13, the fixing member 16 of the present embodiment includes a mating portion 161 for forming a fixed mating relationship with the first fixing portion 15, and a blocking portion 162 protruding from at least one side of the mating portion 161 for blocking the rear side portion of the mounting portion 14 and/or the mounting hole 13, and the mating portion 161 is connected to the blocking portion 162, so that the blocking portion 162 can be relatively fixed with respect to the radiation bezel 10 through the mating portion 161, thereby playing a limiting role on the antenna board 20.

In the above embodiment, the matching portion 161 and the resisting portion 162 may be integrally formed, for example, by milling, injection molding, or may be integrally formed by split type processing, and then assembled to form an integral body, for example, after the matching portion 161 and the resisting portion 162 are respectively formed, they are connected to form the fixing member 16 by clamping, screwing, welding, or the like.

Taking the first fixing portion 15 as a threaded hole formed on the radiation frame 10 as an example, a screw is correspondingly adopted as the fixing piece 16, the matching portion 161 is a threaded section of the screw, and the threaded section is fixedly connected with the threaded hole in a threaded connection manner, the resisting portion 162 is a threaded head of the screw, and the purpose that the threaded head extends towards the mounting hole 13 and/or the mounting portion 14 to resist the rear side of the mounting hole when the threaded section is connected with the threaded hole in a manner of radially protruding from the threaded section is achieved.

In the present embodiment, in order to improve the compactness of the frame antenna structure, the first fixing portion 15 is provided on the adjacent side of the mounting portion 14, and the abutting portion 162 extends to the rear side of the mounting portion 14 in a state where the fixing piece 16 is mounted on the first fixing portion 15 by the engaging portion 161, so that the antenna board 20 is restrained by the restraining portion 27.

As a further embodiment, the fixing member 16 may be configured as an electrical conductor, so that the fixing member 16 is electrically contacted with the antenna board 20 and the radiation frame 10, respectively, to achieve the effect of grounding the antenna board 20.

As an alternative embodiment, the antenna board 20 may also be provided with a ground feed, where the ground feed is electrically contacted to the radiation frame 10, so that the antenna board 20 is grounded.

As a solution that can be independent from or combined with the above-mentioned configuration of the first fixing portion 15 and the fixing member 16, referring to fig. 7-8, the radiation frame 10 is further provided with a second fixing portion 17, where the second fixing portion 17 is located in the accommodating space 11 and is disposed on an adjacent side of the through hole 12, and the second fixing portion 17 is configured to limit the movement of the antenna board 20 along the direction perpendicular to the water product.

It can be appreciated that the second fixing portion 17 is disposed adjacent to the through hole 12, so as to improve the compactness of the frame antenna structure, and because the front side of the antenna board 20 is close to the through hole 12 in the state of being mounted on the radiation frame 10, the second fixing portion 17 is disposed adjacent to the through hole 12, which is more beneficial to forming a limit fit relationship with the antenna board 20, thereby saving the processing material of the second fixing portion 17 and saving the accommodation space 11 occupied by the second fixing portion 17.

Here, the second fixing portion 17 and the body of the radiation frame 10 may be an integral piece, for example, in the case where the radiation frame 10 is a section, the second fixing portion 17 may be integrally extruded with the body of the radiation frame 10, and in the case where the radiation frame 10 is a sheet metal part, the second fixing portion 17 may be formed by cutting a part of the section frame and bending the cut part. Of course, the second fixing portion 17 may also be a component machined separately from the radiation frame 10, and may be subsequently connected to the radiation frame 10 by a connection method commonly used in the mechanical field.

With continued reference to fig. 8, taking the structural form of the integral piece of the second fixing portion 17 and the radiation frame 10 as an example, the second fixing portion 17 includes a first limiting rib 171 and a second limiting rib 172, in an embodiment, the first limiting rib 171 and the second limiting rib 172 are disposed in the accommodating space at intervals and parallel to each other, so that a mounting gap 174 is formed between the first limiting rib 171 and the second limiting rib 172, and the mounting gap 174 is used for providing insertion of the antenna board 20, so as to play a role in limiting the freedom of movement of the antenna board 20 in the vertical horizontal direction.

It should be noted that, in the same principle as the assembly position of the mounting portion 14, the first limiting bead 171 and the second limiting bead 172 are disposed in a manner depending on the form of the antenna board 20 assembled in the accommodating space 11. For example, when the antenna board 20 needs to be matched with the radiation frame 10 along the vertical direction, the first limiting rib 171 and the second limiting rib 172 can be disposed in the accommodating space 11 along the vertical direction parallel to the antenna board 20, and when the antenna board 20 is matched with the radiation frame 10 along the horizontal direction (parallel to the radiation frame 10), the first limiting rib 171 and the second limiting rib 172 can be disposed along the horizontal direction parallel to the radiation frame 10, so as to ensure that the antenna board 20 can be inserted into the mounting gap 174, and the opposite sides (upper side and lower side) of the antenna board 20 can be disposed opposite to the first limiting rib 171 and the second limiting rib 172, respectively. It should be understood that the size of the mounting gap 174 needs to be set to be the size matched with the thickness of the antenna board 20, so that a certain gap exists between the front side board edge of the antenna board 20 and the first limiting rib 171 and the second limiting rib 172 while the front side board edge of the antenna board 20 is placed in the mounting gap 174, or a certain abutting relationship is kept between the front side board edge of the antenna board 20 and the first limiting rib 171 and the second limiting rib 172, the antenna board 20 is clamped in the mounting gap 174 to ensure that the antenna board 20 and the radiation frame 10 are detachable, and the first limiting rib 171 and the second limiting rib 172 also play a role in limiting the movement of the front side of the antenna board 20 in the direction perpendicular to the horizontal direction, finally, under the cooperation of the second fixing portion 17 and the mounting portion 14, the movement freedom of the antenna board 20 in the direction perpendicular to the horizontal direction can be completely limited, and the movement freedom of the mounting portion 14, the fixing member 16 and the radiation frame 10 in the direction can be completely limited.

Referring to fig. 9-10, in an embodiment, in order to ensure that reliable electrical connection is formed between the first feeding point 21, the second feeding point 22 and the radiation frame 10, a first conductive spring piece 23 and a second conductive spring piece 24 are further disposed on the antenna board 20, the first conductive spring piece 23 is fixedly disposed on the feeding point of the first feeding point 21, the second conductive spring piece 24 is fixedly disposed on the second feeding point 22, and the first conductive spring piece 23 and the second conductive spring piece 24 are both abutted against the radiation frame 10 to conduct the antenna circuit and the radiation frame 10.
