[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a mobile phone frame, please refer to fig. 2 to 4, the mobile phone frame provided by the invention comprises an outer frame 10 and a middle plate 20, wherein the outer frame 10 is obtained by bending a titanium alloy strip material with a predetermined size, and the middle plate 20 can be arranged in the outer frame 10 in a fixing mode such as welding connection, clamping connection and the like.
The manufacturing process of the handset frame will be described below with reference to the accompanying drawings.
Firstly, the titanium alloy strip 100 shown in fig. 5 is bent into the shape shown in fig. 6 by a predetermined size, which is determined according to the requirements of a specific mobile phone model.
In an embodiment, the outer frame 10 may be formed by bending a strip of titanium alloy 100, or the outer frame 10 may be formed by folding two strips of titanium alloy 100 as shown in fig. 6, where each strip of titanium alloy 100 includes a main body 101, a first folding strip 102 extending from one end of the main body 101, and a second folding strip 103 extending from the other end of the main body 101. The titanium alloy strip 100 is adopted as the outer frame 100, so that materials are saved, and the strength is greatly improved.
In an alternative embodiment of the present invention, the first tab 102 and the second tab 103 are of different lengths. As shown in fig. 6, the first fold 102 of the left titanium alloy strip 100 is shorter relative to the second fold 103. Of course, in other examples, the lengths of the first flap 102 and the second flap 103 may be the same.
After the titanium alloy strip 100 is bent to a predetermined size to form the shape shown in fig. 6, the outer frame 10 is subjected to numerical control processing, for example, necessary structures such as the charging groove 110, the side reinforcing groove 120, and the audio jack 130 are processed on the titanium alloy strip 100. In addition, in order to facilitate the cooperation with the middle plate 20, a fixing base 140 is further formed on the outer frame 10 to support the middle plate 20.
Referring to fig. 8, in the embodiment of the present invention, the intermediate plate 20 is preferably an aluminum plate 200, and the aluminum plate 200 has the characteristics of light weight and easy processing, and is formed into a predetermined shape by stamping, as shown in fig. 9, through holes 210, assembly grooves 220, and the like by stamping. The aluminum plate 200 is adopted as the intermediate plate 20, so that the processing time is saved, and the material is saved. Of course, the present invention is not limited to the material of the intermediate plate 20, and the intermediate plate 20 may be made of titanium alloy or other materials.
Referring to fig. 10, the titanium alloy strip 100 and the aluminum plate 200 may be combined by welding or snap-fit connection after the above-mentioned processes.
Referring to fig. 11, after the processed titanium alloy strip 100 is combined with the processed aluminum plate 200, an end groove 140 is further formed in the outer frame 10 to allow a wireless signal to pass therethrough.
The invention can improve the processing efficiency of the mobile phone shell and simultaneously improve the product quality of the mobile phone shell.
Different from the traditional method for manufacturing the mobile phone frame, the mobile phone frame is processed into two parts, namely the outer frame 10 and the middle plate 20, wherein the outer frame 10 is made of a high-hardness material (such as titanium alloy), the middle plate 20 is made of an aluminum material (titanium alloy can be adopted, cost is mainly considered, and the high-hardness material is not needed inside the mobile phone), and the processing technology is as above, so that on one hand, the whole aluminum plate is not required to be machined, but the titanium alloy section 10 is cut, and the middle plate 20 is die-cast, so that the processing time is saved, and the efficiency is improved; meanwhile, the outer frame 10 is made of a high-hardness material, so that the mobile phone shell is firmer, not easy to deform and not easy to scratch.
The invention has the advantages of less die casting processing amount, short processing time and the like, and also avoids the defects of difficult surface treatment and the like caused by the incompact die casting material, and the like.
In addition, the invention also provides a mobile phone, which comprises components known to those skilled in the art, such as a screen, a circuit board unit, a battery module and the like, and the mobile phone frame, wherein the battery module supplies power to the screen and the circuit board unit, and the mobile phone frame supports the installation of the screen, the circuit board unit and the battery module.
Referring to fig. 12, fig. 12 is a flowchart of a method for manufacturing a frame of a mobile phone according to a preferred embodiment of the invention.
The invention also provides a manufacturing method of the mobile phone frame, which comprises the following steps:
and S110, bending the titanium alloy strip material to form an outer frame according to a preset size. In this step, the outer frame may be folded from one strip of titanium alloy, or the outer frame may be folded from two strips of titanium alloy 100 as shown in fig. 6.
And S120, processing the outer frame to form a charging groove, a side health groove, an audio jack and a fixed station.
And S130, performing stamping treatment on the aluminum intermediate plate.
And S140, arranging the middle plate in the outer frame in a welding or clamping connection mode, and forming an end groove on the outer frame. Wherein the end slot is used for allowing wireless signals to pass through.
In summary, it is easily understood by those skilled in the art that the mobile phone frame provided by the present invention adopts the titanium alloy outer frame 10 and the aluminum intermediate plate 20, so that the mobile phone frame has the advantages of simple structure, relatively less processing workload, relatively shorter processing time, high efficiency, high yield, high material utilization rate, convenient manufacture, reliable strength and exquisite appearance. Because the hardness of the titanium alloy is far greater than that of the aluminum alloy, the mobile phone frame made of the titanium alloy is more difficult to scratch.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
