Description

Shell assembly and electronic equipment

Technical Field

The present disclosure relates to the field of electronic devices, and in particular, to a housing assembly and an electronic device.

Background

With the rapid development of the 5G communication technology, more and more operating frequency bands are supported by the electronic device. Among them, 3GPP (3 rd Generation Partnership Project) defines the Frequency Range (FR) used by 5GNR (5G New Radio), wherein FR1 Frequency range interval is 450-6000MHz, and is also called sub-6G since the Frequency interval is below 6G. Currently, the mainstream 5G electronic devices in the market all work in the FR1 frequency band.

The range of the working frequency bands supported by the 5G electronic device is wide, and accordingly, more working frequency bands of the antenna are needed. In order to enhance the appearance of the 5G electronic device, a metal middle frame is usually adopted to operate as an antenna. In the related art, an avoiding groove used for avoiding or accommodating a Type-C interface is formed in the metal middle frame, and due to the existence of the avoiding groove, when the antenna works, except for current distribution on an antenna radiator, a part of current is concentrated at the avoiding groove, so that the current intensity distributed on the antenna radiator is reduced, and the efficiency of the antenna is lower.

Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In this disclosure, where the context does not dictate to the contrary, use of directional words such as "inner and outer" refers to inner and outer relative to the contour of the component or structure itself. In addition, it should be noted that terms such as "first", "second", and the like are used for distinguishing one element from another, and have no order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings denote the same elements.

In the related art, in an electronic device such as a mobile phone or a tablet pc, a partition groove is generally formed in a side plate of a metal middle frame so as to use a part of a plate body of the side plate as an antenna radiator. In addition, in order to facilitate accommodating and avoiding electronic components such as a Type-C interface, an avoiding groove is generally formed in the metal middle frame, and due to the existence of the avoiding groove, when the antenna operates, besides current distribution on the antenna radiator, a part of current is distributed at the avoiding groove, for example, the current is distributed around the periphery of the avoiding groove, and particularly, the current is concentrated on a plate body between the avoiding groove and a clearance area, so that the current intensity distributed on the antenna radiator is reduced, and the efficiency of the antenna is low.

Based on this, according to a first aspect of the present disclosure, there is provided a housing assembly, as shown in fig. 1 to 3, including a housing main body 1 and a cover 2, the housing main body 1 having a clearance area 111, an antenna radiator 121 extending around a partial circumference of the clearance area 111, and an escape groove 112 arranged at a distance from the clearance area 111; the cover 2 is connected to the case main body 1 and covers the escape groove 112.

By connecting the cover 2 to the case main body 1 and covering the avoidance groove 112, the current intensity of the antenna at the avoidance groove 112 may be reduced, or the current intensity at the avoidance groove 112 may substantially disappear, so that the current intensity of the antenna is mainly concentrated on the antenna radiator 121, and the antenna efficiency may be effectively improved along with the increase of the current intensity on the antenna radiator 121.

The electronic device may be, for example, a mobile phone, a tablet computer, or the like. The present disclosure is described by taking a mobile phone as an example, for example, referring to fig. 1 and fig. 2, the case body 1 may be a middle frame of the mobile phone, the middle frame includes a bottom plate 110 and a side plate 120 disposed around a part of a periphery of the bottom plate 110, the clearance area 111 is opened on the bottom plate 110, the side plate 120 has a partition groove 122 communicating with the clearance area 111, and a part of the periphery of the side plate 120 around the clearance area 111 extends to the partition groove 122 to form an antenna radiator 121.

Thereby, a partial plate body of the side plate 120 of the middle frame is utilized as the antenna radiator 121 to implement the function of the antenna partial frequency band. Taking an IFA (Inverted-F Antenna) Antenna structure as an example, an operating frequency band of the Antenna radiator 121 is mainly between a 1.7-2.7 GHZ frequency band and a 3.3-3.8GHZ frequency band, for example, fig. 4 exemplarily shows a schematic diagram of the operating frequency band of the Antenna at an MHB (1.7-2.7 GHZ) frequency band when no cover is provided, and fig. 5 exemplarily shows a schematic diagram of the operating frequency band of the Antenna at an N78 (3.3-3.8 GHZ) frequency band when no cover is provided.

Fig. 6 schematically shows the operating frequency bands of the antenna before and after the cover is disposed. Where curve a represents the efficiency of the antenna after the cover 2 is arranged and curve b represents the efficiency of the antenna without the cover 2 arranged. As can be seen from FIG. 6, the efficiency of the antenna at the intermediate frequency (2050-2150 MHz) is improved by 0.8dB, and the efficiency at the N78 (3.3-3.8 GHz) frequency band is improved by 2.5dB. Where dB is the ratio of return loss S11.

In conclusion, the efficiency of the antenna can be effectively improved by arranging the covering part 2 under the conditions that the antenna clearance area is not increased and the PCB layout of the original electronic equipment is not changed, so that better use experience is brought to a user.

The present disclosure is described by taking an example of applying the housing assembly to a mobile phone, and it should be understood that after reading the technical solutions of the present disclosure, a person skilled in the art can clearly understand the technical solutions when the housing assembly is applied to other electronic devices such as a tablet computer.

The avoiding groove 112 can accommodate or avoid electronic components inside the electronic device, and for example, when the avoiding groove 112 accommodates USB interfaces such as a Type-C interface, referring to fig. 3, a concave accommodating groove 210 is disposed on a side surface of the covering element 2 facing the housing main body 1. By arranging the receiving slots 210, electronic components, such as Type-C interfaces, in the partially avoided slots 112 can be avoided and accommodated. Wherein, still taking the cell-phone as an example, when the screen subassembly installation of cell-phone and shell main part 1, covering 2 can be located between screen subassembly and the shell main part 1 to when helping promoting antenna efficiency, can reach waterproof sealed effect.

Both the case main body 1 and the cover 2 may be metal pieces, and the cover 2 may be welded to the case main body 1.

In addition, the cover member 2 may be welded to the case main body 1 by any suitable welding process, for example, the cover member 2 may be welded to the case main body 1 by projection welding. Here, referring to fig. 3, the cover member 2 has a welding surface 220 connected to the case main body 1, and the welding surface 220 may have a welding structure (not shown) protruding from the welding surface 220. By arranging the welding structure, the pressure and current density per unit area on the welding surface can be improved, and the productivity can be improved.

The welding structures may be arranged in any suitable manner, for example, the welding structures may be protrusions or burrs protruding from the welding surface 220, which is not limited in this disclosure.

In another embodiment, the cover 2 may be attached to the case main body 1 by conductive adhesive, or the cover 2 may be attached to the case main body 1 by a fastener or the like. The present disclosure is not limited thereto.

Further, aluminum, an aluminum alloy, a magnesium aluminum alloy, stainless steel, a titanium alloy, or the like can be used for the case main body 1. The covering member 2 may be made of aluminum, aluminum alloy, magnesium aluminum alloy, stainless steel, titanium alloy, or the like. The present disclosure is not limited thereto.
