Technical Field

The application belongs to the technical field of communication equipment, and particularly relates to electronic equipment.

Background

With the progress of technology, the performance of electronic equipment is better and better, wherein the more prominent expression is as follows: electronic devices are becoming increasingly thinner and lighter.

The wearable device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 6, an electronic device is disclosed in an embodiment of the present application, and the disclosed electronic device includes a middle frame 100 and an antenna assembly 200.

The middle frame 100 is a basic component of the electronic device, and the middle frame 100 provides a mounting base for the battery 300, the main board, the screen 500, the battery cover 400 and other parts. Besides, the middle frame 100 is used for installing the antenna assembly 200, specifically, the middle frame 100 is provided with an accommodating space 110, the antenna assembly 200 is arranged in the accommodating space 110, and the antenna assembly 200 can be connected to the middle frame 100 through some fixing components, so as to realize the fixed installation of the antenna assembly 200. Of course, the antenna assembly 200 may be fixed to the middle frame 100 by fastening means such as clamping, bonding, and the like.

In some optional embodiments, the middle frame 100 further defines a battery accommodating space for installing the battery 300, and the accommodating space 110 for installing the antenna assembly 200 may be disposed at one side of the battery accommodating space for installing the battery 300, so that compared with a conventional manner of installing the antenna assembly 200 at each corner of the electronic device, the installation manner of the antenna assembly 200 provided in the embodiments of the present application can effectively alleviate a problem that the antenna assembly 200 is shielded by a user when the user operates the electronic device, so as to affect signals of the electronic device. In a specific embodiment, the antenna assembly 200 may be a WIFI antenna, but may also be other radio frequency antennas, which is not limited herein.

The height of the antenna element 200 (i.e., the dimension of the antenna element 200 in the direction from the bottom to the top) is smaller than the width of the antenna element 200, i.e., the entire antenna element 200 can be regarded as a structure similar to an elongated strip. In order to alleviate the problem that the antenna assembly 200 compresses the battery housing space in the width direction of the center 100, it is necessary to orient the height direction of the antenna assembly 200 or the direction opposite to the height direction toward or close to the width direction of the center 100 as much as possible when mounting the antenna assembly 200. Specifically, the bottom of the antenna assembly 200 is disposed adjacent to the inner sidewall 120 of the middle frame 100, and the top of the antenna assembly 200 is disposed adjacent to the outer sidewall 130 of the middle frame 100, so that the antenna assembly 200 stands sideways in the accommodation space 110.

Based on the above arrangement, the space occupied by the antenna assembly 200 in the width direction of the middle frame 100 is effectively reduced, and a larger space is provided for installing the battery 300 in the width direction of the middle frame 100, so that the battery 300 with a larger volume can be selected under the condition that the thickness of the battery 300 is not changed, and the battery 300 has a larger capacity, so that the cruising ability of the electronic device is improved. Therefore, the installation manner of the antenna assembly 200 disclosed in the embodiment of the present application is not only beneficial to the development of the electronic device towards the direction of lightness and thinness, but also enlarges the capacity of the battery 300, so that the endurance of the electronic device is ensured, and the experience of the user is improved to a certain extent.

With respect to the above arrangement, in some optional embodiments, the bottom end surface of the antenna assembly 200 is arranged in parallel with the inner side wall 120 of the middle frame 100, so that the antenna assembly 200 stands vertically on its side in the accommodating space 110. Specifically referring to fig. 1, in the flat state of the electronic device, the antenna assembly 200 stands on the side in the accommodating space 110 in the vertical state, and at this time, in the width direction (the left-right direction in fig. 1) of the middle frame 100, the space occupied by the antenna assembly 200 is the smallest. Therefore, without changing the thickness (up-down direction in fig. 1) dimension of the middle frame 100, a larger volume of the battery 300 can be accommodated, and the capacity of the battery 300 can be increased without increasing the thickness of the battery 300.

In other optional embodiments, the bottom end surface of the antenna assembly 200 is disposed obliquely to the inner side wall 120 of the middle frame 100, so that the antenna assembly 200 obliquely stands on its side in the accommodating space 110. Specifically, in the flat state of the electronic device, the antenna assembly 200 is obliquely and laterally erected in the accommodating space 110, and at this time, in the width direction of the middle frame 100, the space occupied by the antenna assembly 200 is relatively small, that is, smaller than the space occupied by the antenna assembly 200 when being laid horizontally, and larger than the space occupied by the antenna assembly 200 when being vertically and laterally erected. Therefore, the battery 300 having a relatively large volume can be accommodated without changing the thickness dimension of the middle frame 100, so that the capacity of the battery 300 can be increased without increasing the thickness of the battery 300.

Here, the oblique side-standing mode may be that the antenna assembly 200 is rotated by a certain angle around a first axis extending in the thickness direction of the electronic device, or may be that the antenna assembly 200 is rotated by a certain angle around a second axis extending in the length direction of the electronic device. Besides, the antenna assembly 200 may be rotated around the first axis and the second axis at the same time by a certain angle, so that the antenna assembly 200 is disposed in a spatially inclined side-standing manner. The above various inclined arrangement modes can reduce the space occupied by the antenna assembly 200 in the width direction of the middle frame 100 relative to the flat arrangement mode of the antenna assembly 200, and increase the installation space of the battery 300, so that the capacity of the battery 300 is increased under the condition of not increasing the thickness, the cruising ability of the electronic device is improved, the thickness of the electronic device is not increased, and the experience of a user is improved to a certain extent.

In the embodiment of the present application, in order to install the antenna assembly 200 into the accommodating space 110, the arrangement manner of the accommodating space 110 on the middle frame 100 is designed as follows:

in some optional embodiments, the accommodating space 110 is opened on the surface of the inner sidewall 120 of the middle frame 100, and the opening of the accommodating space 110 is disposed toward the inner side of the middle frame 100. Referring to fig. 1 to 3, a surface of the inner sidewall 120 of the middle frame 100 is partially recessed to form a first groove, the first groove is the accommodating space 110, and a notch of the first groove is located on the inner sidewall 120 and faces one side of the battery 300. When the antenna assembly 200 is installed in the accommodating space 110 in this manner, the antenna assembly 200 needs to be placed into the accommodating space 110 from the opening of the accommodating space 110 from the battery 300 side, and the specific installation process is as follows: the battery 300 is removed to leak out of the opening of the accommodating space 110, the antenna assembly 200 is placed in the accommodating space 110, the antenna assembly 200 is fixed to prevent play in the accommodating space 110, and then the battery 300 is mounted to the center frame 100 to cover the opening of the accommodating space 110 by the battery 300. Based on the above, the arrangement mode can facilitate the installation of the antenna assembly 200, and since the notch is arranged on the inner side wall 120, the connection area between the thickness direction of the middle frame 100 and other components, such as the screen 500, the battery cover 400, etc., is not affected, thereby ensuring the stability of the connection between the middle frame 100 and other components.

In view of the relatively weak protection of the antenna assembly 200 in the above-mentioned arrangement, the present application has made an adaptive design, and please continue to refer to fig. 1, the antenna assembly 200 includes an antenna platelet 210, a coaxial socket 220 and a coaxial line 230, wherein the coaxial socket 220 is disposed on a side plate surface of the antenna platelet 210, and the coaxial line 230 is electrically connected to the coaxial socket 220, when the antenna assembly 200 is installed, the coaxial socket 220 is located on a plate surface of the antenna platelet 210 facing a bottom wall of the first groove, and the bottom wall of the first groove faces a notch of the first groove, so that the antenna platelet 210 is located close to the notch and can close the notch, and thus the components such as the coaxial socket 220 can be protected by the antenna platelet 210 to ensure that some components of the antenna assembly 200 are not damaged.

In other optional embodiments, an end surface of the middle frame 100 in the thickness direction is opened with an accommodating space 110, and an opening of the accommodating space 110 is disposed toward one side of the middle frame 100 in the thickness direction. Specifically, one end surface of the middle frame 100 along the thickness direction thereof is partially recessed to form a second groove, the second groove is the accommodating space 110, at this time, the opening of the accommodating space 110 faces one side of the thickness direction of the middle frame 100, and the thickness direction of the middle frame 100 is consistent with the thickness direction of the electronic device, it should be noted that the thickness direction of the electronic device is generally the size of the electronic device in the direction perpendicular to the plane display area of the screen 500. When the antenna assembly 200 is installed in the accommodating space 110 in this way, the antenna assembly 200 can be directly placed in the accommodating space 110 along the thickness direction of the middle frame 100 without disassembling the battery 300, so that the maintenance or repair of the antenna assembly 200 is also convenient; of course, since the end surface of the middle frame 100 in the thickness direction needs to be connected with other components, such as the screen 500, the battery cover 400, and the like, the connection area is reduced to some extent, but since the antenna assembly 200 is disposed on the side in the thickness direction of the middle frame 100, the width of the notch of the second groove is relatively small, so that the influence on the connection with other components on the middle frame 100 is relatively small and negligible, and in this arrangement, the antenna assembly 200 is enclosed between the middle frame 100 and other components mounted in the thickness direction of the middle frame 100, so that a better protection effect can be achieved on the antenna assembly 200.

In some optional embodiments, the accommodating space 110 is opened in the middle of the middle frame 100, so that the antenna assembly 200 installed in the accommodating space 110 is located in the middle region of the electronic device, and the antenna assembly 200 is prevented from being located at the end of the electronic device, so that the user can hardly cover the antenna assembly 200 when operating the mobile phone, and thus the receiving or transmitting of signals by the electronic device is not affected.

In the embodiment of the present application, in order to fix the antenna assembly 200, a fixing member 700 is added, and the fixing member 700 is detachably connected to the middle frame 100.

In some optional embodiments, in the case that the accommodating space 110 is a first groove, a notch of the first groove is formed on the inner side wall 120, at this time, a threaded hole is formed on a bottom wall of the first groove, and the fixing member 700 is a fastening screw, see fig. 1 and fig. 2. When the antenna assembly 200 is installed, the antenna assembly 200 is first placed in the first groove with the coaxial base 220 and the like positioned inside the antenna small plate 210, that is, the antenna small plate 210 is sealed at the notch of the first groove, and then fastening screws are inserted into the mounting holes of the antenna small plate 210 and the front ends of the fastening screws are screwed into the threaded holes, so that the antenna assembly 200 can be firmly fixed in the accommodating space 110 of the center frame 100 by the fastening screws. When disassembly is required, the antenna assembly 200 can be disassembled from the middle frame 100 by only reversely screwing the fastening screws.

By adopting the fastening screw fixing mode, the antenna assembly 200 is convenient to mount or dismount. Of course, the antenna assembly 200 may also be connected to a connecting member, such as a pressing plate, and the connecting member may be fixed on the sidewall of the first groove or on the inner sidewall 120 by a fastening screw, and the fixing position of the antenna assembly 200 is not limited in the embodiments of the present application.

In other alternative embodiments, in the case where the accommodating space 110 is a second groove, a notch of the second groove is provided on the end surface in the thickness direction of the middle frame. In this case, since the size of the accommodating space 110 in the width direction of the middle frame 100 is relatively small, it is not easy to mount the fixing member 700 in the accommodating space 110, and the fixing member 700 may be a fastening screw, so that a screw hole may be provided on one end surface of the middle frame 100 in the thickness direction, as shown in fig. 5. Based on the situation that the antenna assembly 200 is located in the accommodating space 110 and the fixing position of the fastening screw is located outside the accommodating space 110, the pressing sheet 900 is connected to the antenna assembly 200, specifically, the pressing sheet 900 may be connected to the antenna platelet 210, when the antenna assembly 200 is placed in the accommodating space 110, the pressing sheet 900 extends out of the accommodating space 110, a mounting hole is formed in the pressing sheet 900, and the fastening screw penetrates into the mounting hole and is screwed into the threaded hole, so that the antenna assembly 200 is fixedly mounted.

Of course, in addition to the above manner, in some alternative embodiments, the support 800 may be further used to install the antenna assembly 200 in the accommodating space 110, specifically referring to fig. 4, the support 800 is an elastic member, the elastic member may be similar to a concave structure or a ring structure, an inner side of the elastic member forms an installation space, the antenna assembly 200 is disposed in the installation space, when the antenna assembly is installed, the elastic member and the antenna assembly 200 inside the elastic member are installed in the accommodating space 110 together, and the elastic member is clamped in the accommodating space 110 by an elastic force. In order to fix the antenna assembly 200 in the accommodating space 110, a protrusion 810 is formed at least one end of the elastic member, and correspondingly, a slot 140 is formed in a side surface of the accommodating space 110, when the elastic member and the antenna assembly 200 are placed in the accommodating space 110, the protrusion 810 is clamped in the slot 140, so that the elastic member can be limited to be separated from the accommodating space 110, and the protrusion 810 is not easily separated from the slot 140 under the elastic force of the elastic member, and meanwhile, the antenna assembly 200 cannot be separated due to the extrusion effect of the elastic member. Thus, the mounting of the antenna assembly 200 is achieved by the bracket 800. Here, the bracket 800 may be applied to a case where the notch of the first groove is formed in the inner side wall 120, and may also be applied to a case where the notch of the second groove faces the thickness direction of the middle frame 100.

In other embodiments, the holder 800 may be a structural member such as a metal plate, and specifically, the antenna assembly 200 may be mounted on the holder 800, and when the antenna assembly 200 is mounted, the antenna assembly 200 and the holder 800 may be placed together in the accommodation space 110, and a mounting hole for inserting the fixing member 700 may be formed in the holder 800, or the holder 800 may be connected to the pressing plate 900, and a mounting hole for inserting the fixing member 700 may be formed in the pressing plate 900, so that the holder 800 and the antenna assembly 200 may be fixed to the middle frame 100 together by the fixing member 700.

In some optional embodiments of the present application, the coaxial socket 220, the elastic sheet, and the patch are soldered on the antenna platelet 210, and the coaxial socket 220 is used to electrically connect the coaxial line 230 to the antenna platelet 210, so as to electrically connect the antenna platelet 210 to the motherboard through the coaxial line 230. In order to install the coaxial seat 220, the coaxial line 230 and other structures, the accommodating space 110 is designed into a first slot position 111 and a second slot position 112 which are communicated with each other, the antenna small plate 210, the coaxial seat 220 fixed on the antenna small plate 210, the elastic sheet and the like can be placed into the first slot position 111, the coaxial line 230 is partially positioned in the second slot position 112, and one end of the coaxial line 230, which is deviated from the coaxial seat 220, penetrates out of an avoiding space 113 on the side wall of the second slot position 112 so as to be connected with a mainboard. It should be noted that, regarding the specific structure of the antenna assembly 200 and the operation principle thereof, reference is made to the prior art, and detailed description is not provided herein.

Since the coaxial base 220 is mounted on a side surface of the antenna small plate 210 in the thickness direction, in order to improve the mounting firmness, when the antenna assembly 200 is fixed in the accommodating space 110 through the fixing member 700 and the notch of the first groove is formed in the inner side wall 120, the fixing member 700 penetrates through the antenna small plate 210 and is in threaded connection with the threaded hole in the bottom wall of the first groove, so as to fix the antenna small plate 210 and the coaxial base 220 in the accommodating space 110. When the antenna assembly 200 is fixed in the accommodating space 110 by the fixing member 700 and the notch of the second groove is opened at one end face in the thickness direction of the middle frame 100, the fixing member 700 is passed through the pressing piece 900 connected to the antenna assembly 200 or the bracket 800 and screwed with the end face in the thickness direction of the middle frame 100 to fix the antenna platelet 210 and the coaxial base 220 in the antenna assembly 200 by fixing the pressing piece 900.

In addition to the above structure, the electronic apparatus further includes a battery cover 400 and a screen 500, wherein the battery cover 400 is mounted on one side in the thickness direction of the middle frame 100, i.e., the rear surface of the middle frame 100. In order to improve the installation performance between the battery cover 400 and the middle frame 100, the connection region between the battery cover 400 and the middle frame 100 may be filled with foam 600, and the connection region between the battery cover 400 and the middle frame 100 may be buffered and sealed by the foam 600.

The screen 500 is installed at the other side of the thickness direction of the middle frame 100, that is, the front side of the middle frame 100, and the screen 500 functions as a display. In order to improve the installation performance between the screen 500 and the middle frame 100, the connection area between the screen 500 and the middle frame 100 may also be filled with foam 600, and the connection area between the screen 500 and the middle frame 100 is buffered and sealed by the foam 600.

The electronic device disclosed in this embodiment may be an electronic device such as a mobile phone, a tablet computer, an electronic book reader, a game machine, a wearable device (e.g., a smart watch), and the specific kind of the electronic device is not limited in this embodiment.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
