The invention relates to the field of mobile terminal preparation, in particular to a preparation method of a shell assembly, the shell assembly and a mobile terminal.
Background
With the rapid development of semiconductor manufacturing, electronic technology and display technology, the competition of mobile terminals such as mobile phones, tablet computers and notebook computers is also increased. Users and manufacturers have made higher demands on various aspects of electronic products, particularly mobile terminals such as mobile phones, and the electronic products are gradually developing to multi-functionalization and light and thin, and users also have made higher demands on the appearances of the electronic products. The metal shell has more beautiful texture, and is more and more widely applied to various electronic devices. Since the entire metal case forms a shield to prevent the communication of the cellular phone, it is necessary to provide a non-metal antenna element in the metal case.
However, currently, a method for manufacturing a housing assembly, a housing assembly and a mobile terminal still need to be improved.
Disclosure of Invention
The present invention has been completed based on the following findings of the inventors:
at present, all-metal shells of mobile terminals such as mobile phones and the like generally have the problems that an antenna seam needs to be arranged, the appearance effect is not uniform enough, the strength of the metal shell is not good, and the like. The inventor finds out through intensive research and a large number of experiments that the current antenna element is generally arranged inside the mobile phone shell, so that when the mobile phone shell is made of metal, a three-section structure needs to be adopted, and an antenna seam enabling a signal to pass through the shell is formed at the position of the antenna element. That is, in the mobile phone housing, one or more slits are formed through the metal housing, and the slits are filled with an insulating material, so that the metal above and below the slits can be separated by the insulating material (plastic, etc.), thereby forming a void region. However, the above structure requires the antenna isolation groove to be processed and then filled with plastic. The processing mode not only influences the appearance integrity of the product, but also increases the processing time. Further, the void-free region also causes a reduction in the mechanical properties of the metal case as a whole. In addition, if the metal shell can be made multifunctional, the internal volume of the mobile terminal can be further saved, and the mobile terminal is thinned.
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, an object of the present invention is to provide a housing that avoids the preparation of a through slot, and to implement communication of a mobile terminal by disposing an antenna element on the housing.

Therefore, the shell assembly can be simply obtained, and the prepared shell has at least one of the advantages of uniform appearance effect, strong mechanical strength, capability of saving the internal space of the mobile terminal using the shell and the like.

Detailed Description
The following describes embodiments of the present invention in detail. The following examples are illustrative only and are not to be construed as limiting the invention. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products commercially available.
In one aspect of the invention, a method of making a housing assembly is provided. According to an embodiment of the invention, with reference to fig. 1, the method comprises:
s100: forming a matrix
According to an embodiment of the present invention, in this step, the metal material may be subjected to a forming process by means including, but not limited to, stamping, forging, CNC, and the like. Thus, the metal can be processed into a substrate having a certain shape.
According to the embodiment of the present invention, the specific material of the metal forming the base body is not particularly limited, and may be any material known in the art and applicable to a mobile terminal housing such as a mobile phone. For example, it may be, but is not limited to, aluminum alloy, stainless steel, and the like. In this step, the specific shape of the substrate formed after the molding process is not particularly limited as long as it can be assembled with other components constituting the mobile terminal such as a mobile phone in a mutually-fitted manner, and those skilled in the art can flexibly select the substrate as needed. For example, the substrate may be formed by subjecting the metal to processes including, but not limited to, numerical control machining (CNC), stamping, and forging. The shell component formed by the base body can be a back shell of a mobile terminal such as a mobile phone and the like, and can also be a shell comprising a side frame and a back shell. The outward appearance of casing subassembly can be the plane casing, also can be the 2D backshell that the edge has certain radian, or wholly have the 3D casing of certain radian.
S200: forming a concave groove
According to an embodiment of the invention, in this step, on the previously formed substrate, at least one concave groove is formed. The bottom of each concave groove is provided with at least one connecting hole penetrating through the base body. According to an embodiment of the present invention, the processing manner of forming the concave groove is not particularly limited, and a person skilled in the art may select a familiar metal processing method. Therefore, the concave groove can be used for providing a containing space for the antenna element arranged in the subsequent step, and the antenna element arranged in the concave groove can be connected with a hardware structure such as an antenna feed element through the connecting hole so as to realize the radiation of an antenna signal.
According to a specific embodiment of the present invention, the concave groove is provided by the steps of: firstly, a groove body with a depth smaller than the thickness of the base body is formed on the base body. Then, at the bottom of the groove body, a connection hole penetrating the base body is formed so as to form a groove. The specific arrangement position of the connecting hole can be selected according to the specific position of a hardware structure, such as an antenna feed piece, of the mobile terminal applying the shell assembly.
Alternatively, according to another embodiment of the present invention, the concave groove may be further provided by: first, a connection hole penetrating through the base body is formed in the base body. Then, based on the position of the connection hole, the metal base body is subjected to a treatment such as etching or the like to both sides so as to expand the groove body on the base body. The connecting hole is positioned at the bottom of the groove body so as to form a groove.
According to an embodiment of the present invention, the number and specific shape of the concave grooves are not particularly limited. In the present invention, the concave groove is used to accommodate the antenna element so as to dispose the antenna element on the base body. Therefore, the shape of the concave groove and the position on the base are determined by the number and the position of the antenna elements. According to an embodiment of the invention, the depth of the concave groove is smaller than the thickness of the base body. That is, the concave groove does not extend through the substrate. According to a particular embodiment of the invention, the depth of the concave grooves (distance from the top of the concave grooves to the bottom of the concave grooves) does not exceed 50% of the thickness of the substrate (distance from the top of the concave grooves to the bottom of the substrate). This can avoid formation of a large-area penetrating slit or the like on the substrate, and can ensure the overall mechanical strength of the substrate. For example, according to an embodiment of the present invention, two concave grooves may be formed on both upper and lower sides of the base. Alternatively, when the substrate is an integral substrate including side frames, the concave groove may be provided at the position of the side frame.
S300: provided with an antenna element
According to an embodiment of the present invention, the antenna element may be formed of at least one of a metal, a conductive polymer, and L DS material.
According to an embodiment of the present invention, an antenna element formed of the above material can perform a function of an antenna element due to conductivity, and the antenna element can be easily filled in a concave groove formed in the front by filling, depositing, or the like, and according to a specific embodiment of the present invention, the antenna element can be formed by filling L DS material in the concave groove and alloying, L DS material is a modified plastic containing an organometallic compound which can be activated by laser irradiation or the like to release metal particles from the organometallic compound, and thus, an antenna element having a conductive function can be easily formed in the concave groove.
As will be understood by those skilled in the art, since the base is formed of metal, in order to perform the function of the antenna element, it is necessary to insulate the antenna element from the base, i.e., the concave groove. According to an embodiment of the present invention, the insulation of the antenna element from the concave groove may be achieved by preparing an insulation layer in the concave groove. Specifically, the insulating layer covers the inner surface of the concave groove. That is, the connection holes are not covered with the insulating layer, and the through holes are formed. I.e. all the vertical side walls of the grooves and the bottom surfaces of the grooves are covered by an insulating layer. Therefore, the antenna element can be insulated from the concave groove, and the connecting hole can be reserved for connecting the antenna element and an internal (such as an antenna feed element) structure of the electronic device. According to the embodiment of the present invention, the specific material and arrangement manner of the insulating layer are not particularly limited as long as the insulation can be achieved. For example, the connection holes may be first shielded, and then the insulating paste may be disposed on the inner surface of the concave groove by spraying, printing, dispensing, and the like, so that the insulating layer may be disposed. Or the insulating glue can be directly coated in the concave groove, and then the insulating glue covering the connecting hole is removed, so that the through of the connecting hole can be ensured, and the precision control of the spraying, dispensing and other treatment during the setting of the insulating layer can be reduced. As will be understood by those skilled in the art, since the antenna element is required to be accommodated in the concave groove after the insulating layer is disposed, the thickness of the insulating layer is required to be smaller than the height of the concave groove in order to provide an accommodating space for the antenna element.
In summary, the housing assembly can be simply obtained by the method according to the embodiment of the present invention, and the structure of the prepared housing assembly is shown in fig. 2: at least one connection hole 10 penetrating the base body 100 is provided in the concave groove 200, and the antenna member 300 is insulatedly provided in the concave groove 200. The shell assembly prepared by the method has the function of an antenna, so that the space for arranging the antenna element in the mobile terminal using the shell assembly can be saved, and the obtained shell assembly has uniform appearance effect and strong mechanical strength.
According to an embodiment of the present invention, in order to further improve the performance of the housing assembly prepared by the method, the method may further comprise at least one of the following steps:
setting up connecting piece
According to the embodiment of the present invention, in order to facilitate connection of the antenna element to a hardware structure such as an antenna feed, after the antenna element is filled in the concave groove, a connection member for connecting the antenna element to the antenna feed may be further formed at the connection hole. Specifically, a small section of metal may be deposited on the inner wall of the via, or a copper foil may be disposed on the inner wall of the via to form the connector. Alternatively, a small piece of metal with conductive properties may be provided at the bottom of the connection hole to form the connection member. Therefore, the connection between the antenna element and a hardware structure, such as an antenna feed element arranged in the mobile terminal, can be simply realized.
According to an embodiment of the present invention, the method may further include the step of providing a protective layer. According to an embodiment of the present invention, the protective layer covers the antenna element and the surface of the base body on the side having the concave groove. The protective layer can be set up through technologies such as spraying or high pressure tectorial membrane, can protect the antenna spare on the one hand, on the other hand, can play the effect of decorative appearance effect. Thereby, the performance of the housing assembly prepared by the method can be further improved. According to an embodiment of the present invention, the housing assembly prepared by the above method may have a structure as shown in fig. 3: at least one connection hole 10 penetrating the base body 100 is provided in the concave groove 200, and the antenna member 300 is insulatedly provided in the concave groove 200. A connection member 500 is provided below the connection hole 10, and a protective layer 400 covering the upper surface of the base body 100 and the antenna member 300 is provided on the upper portion (the side where the concave groove is provided) of the base body.

Referring to (c) - (e) of fig. 5, a connection member 500 is provided at the bottom of the connection hole 10. The connection member 500 may be a metal block, and one end of the connection member 500 is in contact with the antenna member 300. Therefore, when the housing is assembled to a mobile terminal such as a mobile phone using the housing, the other end of the connector 500 may contact a reserved terminal, thereby connecting the antenna 300 to a hardware structure. Finally, the protective layer 400 may be formed on the side of the substrate 100 where the concave groove 200 is formed, that is, the outer surface of the substrate 100, by a process such as spraying or high-pressure coating. This can protect the antenna element 300 and prolong the service life thereof, and can further modify the appearance of the housing.
Alternatively, according to another embodiment of the present invention, referring to (a) - (c) of fig. 6, the concave groove 200 and the insulating layer 20 may also be provided by: first, a connection hole 10 penetrating the base body 100 is formed in the base body 100. Subsequently, a groove body is formed at the top of the base body based on the position of the connection hole 10, thereby achieving the arrangement of the groove 200. Then, an insulating paste is applied to the inner surface of the concave groove 200 to form the insulating layer 20. It should be noted that "the top of the base" refers to the upper surface of the base 100, i.e. the surface on the side where the antenna element is arranged, i.e. the surface on the side of the housing assembly facing the external environment in practical use.
In another aspect of the invention, a housing assembly is provided. According to embodiments of the present invention, the housing assembly may be prepared using the methods described above. Referring to fig. 2, the housing assembly includes: a base body 100, at least one concave groove 200, and an antenna element 300. Wherein, at least one connection hole 10 penetrating the base body 100 is provided in the concave groove 200, and the antenna member 300 is insulatively provided in the concave groove 200 to radiate an antenna signal.

According to an embodiment of the present invention, the depth of the concave groove 200 is less than the thickness of the base 100. That is, the concave groove 200 does not penetrate the base 100. According to the embodiment of the present invention, the depth of the concave groove 200 (the distance from the top of the concave groove to the bottom of the concave groove) is not more than 50% of the thickness of the substrate (the distance from the top of the concave groove to the bottom of the substrate 100, except the concave groove provided on the substrate 100). This can avoid formation of a large-area penetrating slit or the like in the substrate 100, and can ensure the overall mechanical strength of the substrate 100.
