Description

Technical Field

[0001] The present invention relates to the technical field of mobile terminal manufacturing, and in particular to an integrated mobile terminal housing and a manufacturing method thereof. Background Art

[0002] Since mobile terminals usually need to be carried, and their functions are increasing, and the displayed content is becoming richer and richer, the thinness and lightness of mobile terminals and the larger display ratio (i.e., larger display area) have become a development trend. Thinness usually adopts an integrated shell structure, which requires the shell of the mobile terminal to meet certain structural strength requirements. Therefore, this type of mobile terminal usually uses metal as the shell. However, mobile terminals usually have wireless communication functions, such as WIFI, 4G, 5G or Bluetooth, etc., which require necessary antennas. The type or applicable frequency of each antenna is different, and they cannot interfere with each other. When an integrated metal is used as the shell, it has a shielding effect on the wireless signal. Usually, an antenna is set on the metal shell, or the antenna and the metal shell form an integrated structure. Since the shell of the mobile terminal is an appearance component, its aesthetics affects the choice of consumers. At present, there is a mobile terminal metal shell with integrated antenna. Nano injection molding technology is usually used in manufacturing, which refers to nano molding technology (NMT, Nano Molding Technology). It is a process that combines metal and plastic with nano technology. The metal shell is first formed by CNC or stamping processes. The plastic is directly molded on the metal surface, and then the metal and plastic are processed as a whole by CNC. Finally, it is nano-processed. The whole is smooth and has a textured appearance. However, due to the repeated use of CNC and other processes, the process is complicated and the cost is high. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide an integrated mobile terminal housing and a manufacturing method thereof, wherein the mobile terminal housing can reduce production costs and improve production efficiency.

[0004] In order to solve the above technical problems, the present invention provides an integrated mobile terminal shell, which includes a shell body and a plastic bracket arranged on the inner side of the shell body, and the plastic bracket is provided with an isolation structure that electrically disconnects the shell body from the antenna. The isolation structure includes a first isolation strip arranged along the length direction of the shell body and a second isolation strip arranged on the side frame of the shell. The first isolation strip is connected to the second isolation strip, and the surface of the first isolation strip is in the same plane with the surface of the shell body, and the surface of the second isolation strip is in the same plane with the surface of the antenna.

[0005] Furthermore, the contact surface between the shell body and / or the antenna and the plastic bracket is provided with a groove, and the corresponding position of the plastic bracket is provided with a protrusion which is positioned in the groove when fixed.

[0006] Furthermore, the side wall of the groove is inclined inwardly so that the projection of the groove bottom perpendicular to the contact surface is greater than the groove opening.

[0007] Furthermore, an elastic layer is formed between the junction of the shell body and the shell side frame and the plastic bracket.

[0008] The present invention provides a method for manufacturing an integrated mobile terminal housing, the method comprising:

[0009] a bracket forming step, for arranging a mobile terminal circuit board, forming at least three side parts and a bracket bottom at least partially connected to the three side parts by an injection molding process, wherein the bracket bottom is provided with a mounting surface for arranging the mobile terminal circuit board and a fixing surface for matching with the fixed housing body, the mounting surface is arranged with fixing positions for installation and fixing, and at least two isolation strips protruding outward are provided on the fixing surface;

[0010] A shell body molding step, forming four continuously closed shell side frames and a shell body at the bottom of the shell connected to the shell side frames;

[0011] An antenna body molding step, wherein a first separation groove is formed on the bottom of the shell body and two second separation grooves are formed on at least one side frame and are respectively connected to the first separation groove. There is at least one connecting portion between the antenna body and the shell body, and the connecting portion is located in the first separation groove. The upper surface of the connecting portion is lower than the outer surface of the shell bottom.

[0012] a coloring step of oxidizing the surface of the shell body with the antenna body and coloring the surface of the isolation strip, so that the antenna body, the surface of the shell body, the first separation groove, the second separation groove and the isolation strip are colored uniformly;

[0013] The antenna body segmentation step is to remove the connection between the antenna body and the shell body from the inner side of the shell body by CNC, so that the antenna body and the shell body are separated to form an independent antenna;

[0014] In the bonding and fixing step, the independent antenna and the shell body are bonded and fixed to the corresponding positions of the bracket respectively, so that the isolation strip is located between the antenna and the shell body, forming an integrated mobile terminal shell with an antenna.

[0015] Furthermore, the thickness of the connecting portion is 1 / 4-1 / 3 of the thickness of the bottom of the shell.

[0016] Furthermore, the height of the isolation strip is the same as the thickness of the shell body.

[0017] Furthermore, the fixing position is provided with a fixing nut.

[0018] Furthermore, the shell body is formed by stamping or CNC.

[0019] Furthermore, the second separation groove is L-shaped.

[0020] Furthermore, the first separation groove is in a strip shape.

[0021] Furthermore, the bracket is a plastic bracket.

[0022] Furthermore, an elastic layer is provided at the junction area between the bottom of the shell and the side frame of the shell.

Since the exposed surfaces of the antenna body, the shell body and the plastic bracket are subjected to coloring treatment, and then the antenna body is separated from the shell body from the inside of the shell body, it can not only ensure the consistency of the surface color after assembly, but also avoid the partial destruction of the colored surface when the antenna body is separated from the shell body after the coloring treatment, resulting in the phenomenon of white exposure between the isolation strip and the antenna body or the shell body after assembly, affecting the appearance of the product. Through experiments, the mobile terminal shell produced by the manufacturing process of the present invention is about 1 / 3 of the cost of the nano injection molding process, which effectively reduces the cost and improves the production efficiency.

[0045] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0046] like Figure 1-2 As shown, the present invention provides an embodiment of an integrated mobile terminal housing.

[0047] The integrated mobile terminal shell includes a shell body 1 with four shell side frames 12 and a plastic bracket 2 arranged on the inner side of the shell body 1. The plastic bracket 2 is provided with an isolation structure that electrically disconnects the shell body 1 from the antenna 112. The isolation structure includes a first isolation strip 22 arranged along the length direction of the shell body 1 and a second isolation strip (not shown in the drawings) arranged on the shell side frame. The first isolation strip 22 is connected to the second isolation strip. Usually, the first isolation strip 22 and the second isolation strip are arranged vertically. After installation, since the antenna 112 is fixed by the plastic bracket 2, the electrical signal isolation is achieved between the antenna 112 and the shell body 1 respectively by the first isolation strip 22 and the second isolation strip. At the same time, the surface of the antenna 112 and the surface of the shell body 1 are in the same plane, so that the antenna 112 is integrated with the shell body 1, which can not only solve the influence of the integrated metal shell on the wireless signal, but also ensure the overall aesthetics of the shell.

[0048] Specifically, the plastic bracket 2 is made of plastic by injection molding or CNC process. The plastic bracket 2 includes at least three bracket sides 20 and a bracket bottom (not shown in the drawings) connected to the bracket sides 20, and a fixing position 21 for mounting a circuit board is provided on the bracket bottom.

[0049] As required, an elastic layer 3 may be formed between the junction of the shell body 1 and the shell side frame 12 and the plastic bracket 2. That is, an elastic layer 3 is provided between the shell body 1 and the plastic bracket 2 at the junction of the shell bottom 11 and the shell side frame 12, and the elastic layer 3 can absorb the impact force received when falling, and avoid direct transmission to the circuit board, resulting in damage to the electrical part.

[0050] In order to improve the fixation and stability of the shell body 1, the antenna 112 and the plastic bracket 2, the contact surface of the shell body and / or the antenna and the plastic bracket is provided with a groove (not shown in the drawings), and the corresponding position of the plastic bracket 2 is provided with a protrusion (not shown in the drawings) which is located in the groove when fixed. The side wall of the groove is inclined inward to form a projection perpendicular to the contact surface from the bottom of the groove that is larger than the opening of the groove. Since the plastic bracket 2 and the shell body 1 are bonded and fixed by hot melt adhesive, when the groove is set to be larger inside and smaller outside, a stable fixing effect can be formed after hot melt fixing.

[0051] As required, a glue overflow groove 23 is provided between the mounting surface of the plastic bracket 2 and the housing bottom 11 or the housing side frame 12 to avoid glue overflow after fixation.

[0052] like Figure 3-12 As shown, the present invention provides an embodiment of a method for manufacturing an integrated mobile terminal housing.

[0053] The integrated mobile terminal housing manufacturing method comprises:

[0054] Plastic bracket molding step S1, specifically, the plastic bracket 2 is usually made of plastic material and injection molded. On the one hand, it is used to configure the mobile terminal circuit board, that is, to fix the mobile terminal circuit board, and on the other hand, it is used to increase the overall strength of the mobile terminal shell. At least three bracket side portions 20 and a plastic bracket bottom at least partially connected to the three bracket side portions 20 are formed by an injection molding process. At least a fixing position 21 for installation and fixation and a mounting surface (not shown in the drawings) for configuring the mobile terminal circuit board are distributed at least at the bottom of the plastic bracket, as well as a plastic bracket 2 for fixing the fixing surface of the shell body 1, and the plastic bracket 2 is provided with at least two isolation strips 22 protruding from the fixing surface; the fixing position 21 can be set as a fixing nut.

[0055] The shell body forming step S2 forms four continuous closed shell side frames 12 and a shell bottom 11 connected to the shell side frames 12; specifically, the shell body is usually made of light alloys such as aluminum and magnesium, and is processed by die casting or CNC forming technology to obtain a square shell, which is surrounded by shell side frames 12 and a shell bottom 11 connected to the shell side frames 12;

[0056] In antenna body forming step S3, the antenna body 111 is separated from the shell body 1, that is, a first separation groove 115 is formed on the shell bottom 11 and two second separation grooves 114 are formed on the shell side frame 12, and the second separation grooves 114 are respectively connected to the first separation grooves 115. The shell body 1 is separated from the part by the first separation groove 115 and the second separation groove 114 as the antenna body 111. There is at least one connecting portion 116 between the antenna body 111 and the shell body 1, that is, there is at least one connecting portion 116 between the shell bottom and / or the shell side frame 12 of the shell body 1, and the connecting portion 116 is located in the first separation groove 115 and / or the second separation groove 114. In this embodiment, the example of the connecting portion 116 being located in the first separation groove 115 is used for explanation. The upper surface of the connecting portion 116 is lower than the outer surface of the bottom of the shell body 1; specifically, at least a portion of the antenna body 111 is connected to the shell body 1, and the thickness of the connecting portion 116 between the shell body 1 and the antenna body 111 is less than the thickness of the bottom of the shell body 1. In order to ensure the stability of the connection during the coloring process and prevent deformation, the thickness of the connecting portion 116 is 1 / 4-1 / 3 of the thickness of the shell bottom 11.

[0057] In the surface treatment step S4, the surface of the shell body 1 with the antenna is subjected to oxidation treatment for coloring and the surface of the isolation strip 22 on the fixed surface of the plastic bracket 2 is subjected to coloring treatment, so that the antenna body 111, the surface of the shell body 1, the first separation groove 115, the side wall of the second separation groove 114 and the surface of the isolation strip 22 are uniformly colored. Specifically, the surface of the shell body 1 with the antenna is subjected to oxidation treatment for coloring, and the surface of the isolation strip 22 on the fixed surface of the plastic bracket 2 is subjected to coloring treatment respectively, so that the surface of the shell body 1 with the antenna is consistent with the surface color of the isolation strip 22; the second separation groove 114 is L-shaped, and the first separation groove 115 is strip-shaped.

[0058] Antenna body segmentation step S5, removing the connection portion 116 between the antenna body 111 and the shell bottom 11 from the inner side of the colored shell body 1 in the above step, so that the antenna body 111 is separated from the shell body 1 to form an independent antenna. Specifically, the connection portion 116 is removed from the inner side of the colored shell body 1 by CNC process, so that the antenna body 111 is separated from the shell body 1;

[0059] In the bonding and fixing step S6, the independent antenna and the shell body 1 are respectively bonded and fixed to the corresponding positions of the plastic bracket 2, so that the isolation strip 25 is located between the antenna and the shell body 1, and restored to the shape without the first separation groove 115 and the second separation groove 114, so as to form an integrated mobile terminal shell with an antenna, such as Fig.11 As shown, the independent antenna and the shell body 1 are usually fixed with the adhesive plastic bracket 2 by hot-melt process. In order to avoid glue overflow during bonding, a glue overflow groove 23 is provided between the mounting surface of the plastic bracket and the bottom 11 of the shell. Fig. 9The height of the isolation strip 25 is the same as the thickness of the bottom 11 of the housing, and the shape is consistent with the first separation groove 115 and the second separation groove 114. After installation, the surface of the housing body 1 is flat, and during assembly, an electrical connection is formed between the antenna and the circuit board, which can ensure that the antenna receives signals without being affected by the material of the housing.

[0060] In this embodiment, taking the three antennas integrated in the shell as an example, a connecting portion 116 is provided between the antenna body and the shell body 1 during the manufacturing process. It can also be set that a connecting portion 116 is provided between the middle antenna body and the antenna bodies on both sides, and a connecting portion 116 is provided between the antenna bodies on both sides and the shell body 1. The manufacturing process and effect are the same and will not be repeated.

[0061] As required, the side portion 20 of the bracket is provided with an airtight opening or through hole. Since the surfaces of the antenna body, the shell body and the exposed part of the plastic bracket are subjected to coloring treatment, the surface color after assembly can be guaranteed to be consistent. At the same time, it can also avoid local damage to the oxidized surface when the antenna body is separated from the shell body after the coloring treatment, resulting in whitening after assembly, affecting the appearance of the product. In addition, the number of CNC processes can be reduced and production time can be saved, effectively reducing production costs and improving production efficiency. Through experiments, the manufacturing process cost of the present invention is about 1 / 3 of the cost of the nano injection molding process.

[0062] In order to improve the stress strength of the shell body, an elastic layer is provided between the shell body 1 and the plastic bracket 2 at the junction area of ​​the shell bottom 11 and the shell side frame 12. The elastic layer can absorb the impact force when falling and avoid direct transmission to the circuit board, causing damage to the electrical part.

[0063] like Fig.13 As shown, in the method for manufacturing an integrated mobile terminal housing of the present invention, the above effect can also be achieved by first performing step S2 and then performing step S1. That is, there is no order requirement for step S1 and step S2.

[0064] Specifically, the integrated mobile terminal housing manufacturing method includes:

[0065] A shell body molding step, forming four continuously closed shell side frames and a shell body at the bottom of the shell connected to the shell side frames;

[0066] An antenna body molding step, wherein a first separation groove is formed on the bottom of the shell body and two second separation grooves are formed on at least one side frame and are respectively connected to the first separation groove. There is at least one connecting portion between the antenna body and the shell body, and the connecting portion is located in the first separation groove. The upper surface of the connecting portion is lower than the outer surface of the shell bottom.

[0067] a bracket forming step, for arranging a mobile terminal circuit board, forming at least three side parts and a bracket bottom at least partially connected to the three side parts by an injection molding process, wherein the bracket bottom is provided with a mounting surface for arranging the mobile terminal circuit board and a fixing surface for matching with the fixed housing body, the mounting surface is arranged with fixing positions for installation and fixing, and at least two isolation strips protruding outward are provided on the fixing surface;

[0068] a coloring step of oxidizing the surface of the shell body with the antenna body and coloring the surface of the isolation strip, so that the antenna body, the surface of the shell body, the first separation groove, the second separation groove and the isolation strip are colored uniformly;

[0069] The antenna body segmentation step is to remove the connection between the antenna body and the shell body from the inner side of the shell body by CNC, so that the antenna body and the shell body are separated to form an independent antenna;

[0070] In the bonding and fixing step, the independent antenna and the shell body are respectively bonded and fixed to the corresponding positions of the bracket, so that the isolation strip is located between the antenna and the shell body, forming an integrated mobile terminal shell with an antenna. Other processes and effects are the same as those in the above embodiment and will not be repeated.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
