Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, in one embodiment, a shielding structure is provided, which includes an antenna 100, a first shielding frame 200, a second shielding frame 300, and a connector 400. Thus, the first shielding frame 200, the second shielding frame 300 and the connecting member 400 can be used to assemble and connect the antenna 100 and the external device 500, so that the antenna 100 can be electrically connected to the external device 500, thereby ensuring that signal transmission between the antenna 100 and the external device 500 does not cause crosstalk to the radiating element and ensuring the radiation performance of the radiating element.

As shown in fig. 1 to 4, specifically, the antenna 100 includes a mounting substrate 110; the first shield frame 200 is connected to the mounting baseplate 110; the second shielding frame 300 and the first shielding frame 200 are at least partially overlapped, and the first shielding frame 200 and the second shielding frame 300 can be enclosed into a shielding cavity 600; the lower side of the connector 400 is fixedly connected to the upper side of the second shield frame 300, and the upper side of the connector 400 is movably connected to the mounting base plate 110, so that the second shield frame 300 can move back and forth in a direction (as shown in a direction a in fig. 1 to 3) approaching or separating from the mounting base plate 110.

In the shielding structure of the above embodiment, the upper side of the first shielding frame 200 and the mounting base plate 110 of the antenna 100 are connected and fixed by riveting, screwing, welding or clamping; then, the lower side of the second shielding frame 300 is fixedly connected with the shell of the external device 500 in a riveting mode, a screwing mode, a welding mode or a clamping mode; then, the lower side of the connecting piece 400 is fixedly connected with the upper side of the second shielding frame 300 in a riveting, screwing, welding or clamping manner; the antenna 100 can be electrically connected to the external device 500 by the movable connection between the upper side of the connector 400 and the mounting board 110. Because the second shielding frame 300 and the first shielding frame 200 are at least partially overlapped, and the first shielding frame 200 and the second shielding frame 300 can be enclosed into the shielding cavity 600, it can be ensured that signal transmission between the antenna 100 and the external device 500 does not cause crosstalk to the radiating element, and the radiation performance of the radiating element is ensured. Meanwhile, after the upper side of the connecting member 400 is movably connected to the mounting base plate 110, the second shielding frame 300 can move back and forth relative to the mounting base plate 110 in a direction close to or away from the mounting base plate 110, so that the mounting position of the mounting base plate 110 can be flexibly adjusted in a height direction (as shown in a direction a of fig. 1 to 3), and further, the cumulative tolerance of the assembly body 510 of the external device 500 generated in the assembling process can be adapted, and after the antenna 100 and the external device 500 are fixedly mounted, the antenna 100 can be prevented from being deformed, and the index cannot be affected.

For example, when the external device 500 includes four assemblies 510, the installation tolerance of each assembly 510 is 0.5mm, and the cumulative tolerance of the four assemblies 510 is 2 mm. In a conventional mounting manner of the antenna 100 and the external device 500, if the cumulative tolerance is +2mm, after the antenna 100 and the external device 500 are mounted and fixed, the antenna 100 is subjected to a contact force under the influence of the cumulative tolerance, so that the antenna 100 is deformed; if the cumulative tolerance is-2 mm, the antenna 100 may be subjected to a pulling force and thus the antenna 100 may be deformed under the influence of the cumulative tolerance after the antenna 100 is fixedly mounted to the external device 500. The shielding structure of the above embodiment flexibly adjusts the mounting position of the mounting base plate 110 in the height direction by reciprocating the second shielding frame 300 relative to the mounting base plate 110 in the height direction, for example, when the cumulative tolerance is +2mm, the mounting position of the mounting base plate 110 is correspondingly moved up by 2 mm; when the accumulated tolerance is-2 mm, the mounting position of the mounting base plate 110 is correspondingly moved downwards by 2mm, so that the mounting of the antenna 100 can adapt to the accumulated tolerance, the antenna 100 is prevented from being influenced by external force, the antenna 100 is prevented from deforming, the index cannot be influenced, and the performance of the antenna 100 is ensured. Especially for the already assembled external device 500, the antenna 100 can be adapted to be mounted and fixed with the already assembled external device 500.

Wherein, first shield frame 200 and second shield frame 300 all are frame construction, and it can be integrated into one piece's structure, also can be the structure that the concatenation formed, only need satisfy first shield frame 200 and second shield frame 300 and can enclose and establish into shielded cavity 600, guarantee that the signal transmission between antenna 100 and the external equipment 500 can not cause the cross talk to the radiating element, guarantee that the radiation performance of radiating element can. For example, the first shielding frame 200 and the second shielding frame 300 may be formed by sequentially connecting and enclosing four shielding plates end to end.

Alternatively, the projection of the second shadow frame 300 on the mounting baseplate 110 falls within the projection area of the first shadow frame 200 on the mounting baseplate 110. As such, the length of the second shielding frame 300 (e.g., the length in the direction B of fig. 1 and 2) is smaller than the length of the first shielding frame 200 (e.g., the length in the direction B of fig. 1 and 2), and the width of the second shielding frame 300 (e.g., the length in the direction C of fig. 1 and 2) is smaller than the width of the first shielding frame 200 (e.g., the length in the direction C of fig. 1 and 2), so that the second shielding frame 300 can be disposed in the first shielding frame 200, i.e., the area of the region surrounded by the outline of the second shielding frame 300 is smaller than the area of the region surrounded by the outline of the first shielding frame 200. The outer sidewall of the second shield frame 300 is spaced apart from the inner sidewall of the first shield frame 200. In this way, a gap (as shown by L in fig. 4) is left between the outer sidewall of the first shielding frame 200 and the inner sidewall of the first shielding frame 200, so that intermodulation of the antenna 100 is not affected, which is beneficial to improving intermodulation indexes. In combination with the first shielding frame 200 and the second shielding frame 300 at least partially overlapping, the shielding cavity 600 enclosed by the first shielding frame 200 and the second shielding frame 300 can also have sufficient shielding effect. The gap between the outer sidewall of the first shielding frame 200 and the inner sidewall of the first shielding frame 200 may be flexibly selected or designed according to actual shielding requirements, for example, may be 0.8mm to 1.2mm, preferably 1mm, so as to ensure the shielding effect and not to affect intermodulation indexes.

It should be noted that the second shielding frame 300 at least partially overlaps the first shielding frame 200, which means that at least a portion of the projection of the second shielding frame 300 falls on the first shielding frame 200 in the width direction (e.g., the C direction in fig. 1 and 2) or the length direction (e.g., the B direction in fig. 1 and 2), even if the second shielding frame 300 moves in the height direction with respect to the first shielding frame 200, the second shielding frame 300 and the first shielding frame 200 can be ensured to enclose the shielding cavity 600 and have a sufficient shielding effect.

In one embodiment, the mounting baseplate 110 is provided with a first connection portion (not labeled). A second connection portion (not labeled) is disposed on an upper side of the second shield frame 300. The connecting member 400 is provided with a third connecting portion (not labeled) and a fourth connecting portion (not labeled). Therefore, the second shielding frame 300 can move back and forth along the height direction only by connecting and fixing the third connecting portion and the second connecting portion and then by using the movable connection between the fourth connecting portion and the first connecting portion, so that the mounting position of the mounting base plate 110 can be adjusted in the height direction, accumulated tolerance can be adapted, and the antenna 100 and the external device 500 are guaranteed not to deform after being mounted and fixed.

As shown in fig. 7, in particular, the connecting member 400 includes a connecting body 410, a first flange 420 disposed on an upper side of the connecting body 410, and a second flange 430 disposed on a lower side of the connecting body 410, the connecting body 410 is provided with a third connecting portion, and the connecting body 410, the first flange 420, and the second flange 430 cooperate to form a fourth connecting portion. Thus, the connection body 410 can be stably and reliably fixed on the upper side of the second shielding frame 300 by using the connection and fixation of the third connecting portion and the second connecting portion; the movable connection between the fourth connection portion formed by the connection body 410, the first flange 420 and the second flange 430 and the first connection portion on the mounting base plate 110 is utilized, so that the second shielding frame 300 can move in the height direction relative to the mounting base plate 110, and the mounting position of the mounting base plate 110 relative to the external device 500 in the height direction can be adjusted. The connecting body 410 may be in a column or strip shape, and the connecting body 410, the first flange 420 and the second flange 430 may be integrally formed in an i-shape.

In addition, the movable connection between the fourth connecting portion and the first connecting portion can be realized in a clamping manner or in a plugging manner, and only the requirement that the second shielding frame 300 can move in the height direction relative to the mounting base plate 110 is met.

As shown in fig. 5 and 6, in one embodiment, the first connecting portion is provided with a card slot 111. The engaging groove 111 can engage with the connecting body 410, and the connecting body 410 can reciprocate along the length direction of the connecting body 410 relative to the mounting base plate 110. In this way, after the connecting body 410 is clamped into the clamping groove 111, the connecting body 410 can move along the length direction of the connecting body, so that the second shielding frame 300 can move back and forth along the height direction relative to the installation base plate 110, and the installation position of the installation base plate 110 in the height direction can be adjusted. The width of the card slot 111 (shown as F in fig. 6) is smaller than the width of the first flange 420 (shown as K in fig. 7) and the width of the second flange 430 (shown as H in fig. 7). In this way, in the moving process of the connecting body 410, the first flange 420 or the second flange 430 can collide with the mounting base plate 110, so as to prevent the connecting body 410 from falling off from the slot 111, and limit the moving amount of the second shielding frame 300 relative to the mounting base plate 110.

As shown in fig. 6, the mounting base plate 110 is further provided with an introduction groove 112, the introduction groove 112 communicates with the locking groove 111, and a width (shown as G in fig. 6) of the introduction groove 112 is greater than or equal to a width of the first flange 420. Thus, the guiding function of the guiding groove 112 is utilized to facilitate the connection body 410 to enter the slot 111, and the connection member 400 is convenient to be assembled and connected with the installation bottom plate 110. The guiding groove 112 and the locking groove 111 may be communicated to form a T-shaped groove, the locking groove 111 may be a small end of the T-shaped groove, and the guiding groove 112 may be a large end of the T-shaped groove. Of course, in other embodiments, the introduction groove 112 may also be in a flared shape, and only needs to be able to introduce the connection body 410 into the slot 111.

Wherein, the number and the arrangement position of the connecting pieces 400 can be flexibly selected or designed according to the actual installation requirement.

As shown in fig. 2, in one embodiment, the number of the connectors 400 is at least two. At least one connecting member 400 is disposed on one side of the mounting base plate 110, at least one connecting member 400 is disposed on the other side of the mounting base plate 110, and the connecting members 400 are disposed in one-to-one correspondence with the slots 111. So, make connecting piece 400 distribute in the relative both sides of mounting plate 110, for example, make connecting piece 400 distribute in the left side and the right side of mounting plate 110, utilize the conflict between the inner wall of connecting body 410 and draw-in groove 111, can restrict the relative connecting body 410 of mounting plate 110 and take place and control the drunkenness, combine mounting plate 110 and first flange 420 and second flange 430's conflict, also can restrict the relative connecting body 410 of mounting plate 110 and take place the transition of upper and lower direction and remove, guarantee the realization installation that mounting plate 110 can be accurate, the assembly precision is improved. In addition, the mounting base plate 110, the first shielding frame 200, the second shielding frame 300, and the connecting member 400 may be assembled in advance, and then, after the lower side of the second shielding frame 300 is connected to the external device 500, the external device 500 may be fixedly connected to the mounting base plate 110, so that the assembly efficiency is high.

In one embodiment, two connectors 400 are distributed on the left side of the mounting base plate 110 along the length direction, two connectors 400 are distributed on the right side of the mounting base plate 110 along the length direction, and each connector 400 is arranged corresponding to one clamping groove 111. In this manner, not only the left-right play of the mounting baseplate 110 can be restricted by the four links 400, but also the mounting position of the mounting baseplate 110 in the height direction can be adjusted. Of course, in other embodiments, the connecting member 400 can also be arranged in the width direction of the mounting body.

The third connecting part and the second connecting part can be fixedly connected through modes such as screw joint, riveting, welding or clamping.

As shown in fig. 6, in one embodiment, the third connection portion is provided with a first connection hole 411, and the second connection portion is provided with a second connection hole 310 correspondingly communicating with the first connection hole 411. The shielding structure further includes a first fastening member (not shown) capable of being tightly fitted with the first connection hole 411 and the second connection hole 310.

When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements be perpendicular, but certain vertical tolerances may exist due to manufacturing and assembly concerns. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

It should also be understood that in explaining the connection relationship or the positional relationship of the elements, although not explicitly described, the connection relationship and the positional relationship are to be interpreted as including a tolerance range which should be within a deviation range acceptable by a specific value determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
