Now, with the development of communication technology, users have increasingly high requirements on various aspects of mobile phones, especially requirements on appearances of mobile phones, and have pursued not only higher screen occupation ratios but also light weight, thinness, and beautiful appearances such as colors and shapes of appearances. Various appearances have been researched by various manufacturers and research units, and the requirements of users are greatly met. But at the same time presents difficulties in the manufacture of the handset. For example, in order to reduce the weight of the mobile phone, a light material needs to be selected, and the size of the mobile phone needs to be reduced as much as possible, so that the strength of the components of the mobile phone is reduced, and the processing difficulty is increased.
In order to beautify the appearance, most of mobile phones at present adopt titanium alloy materials to manufacture appearance parts of the mobile phones, for example, the appearance of the mobile phones is formed by materials with different upper and lower parts, and the titanium alloy materials greatly improve the appearance of the mobile phones and meet the requirements of customers.

The second part is made of metal material which is lighter than titanium alloy, and because titanium alloy is expensive and difficult to process, and the weight per unit volume is large, in the embodiment, the second part serving as the middle plate is relatively large in volume, and a non-titanium alloy plate such as an aluminum alloy plate or an aluminum plate is adopted, so that the overall weight of the structural member is reduced, the cost is reduced, and the difficulty of the overall processing process is reduced.
In one embodiment, a grooved profile 412 is further provided on a surface of the first part 400 opposite to the second part 500, and a grooved profile 620 is further provided on a surface of the third part 600 opposite to the second part 500.
A channel 412 is provided on the surfaces of the first and third members 400 and 600 for installing other structural members by which the first and second members 400 and 500 are coupled and the coupling between the third member 600 and the second member 500 enhances the strength of the middle frame structural member. The channel member 412 enhances the strength of fixing other members by being provided in a channel-type structure.
In one embodiment, a plastic member is connected between the first member 400 and the second member 500 through the channel member 412, and the first member 400 and the second member 500 are connected through the plastic member. A plastic member is connected between the third member 600 and the second member 500 through the channel member 620, and the third member 600 and the second member 500 are connected through the plastic member.
The strength of the middle frame structure is enhanced by connecting the first member 400 and the second member 500, and the third member 600 and the second member 500 by the plastic members. The plastic part is connected with the groove-shaped part 412, and the groove-shaped structure of the groove-shaped part 412 is filled with plastic, so that the strength of fixing the plastic part is enhanced, and the plastic part is not easy to fall off.
In one embodiment, the first member 400 includes a first end plate 410 and a second end plate 420, the first end plate 410 and the second end plate 420 being separated by a gap 430.
A slot is provided in a clearance area of the middle frame member, and the slot antenna is configured by combining a feeding member which radiates electromagnetic waves to the outside through the slot.
In one embodiment, a first connection structure 411 is disposed on the first end plate 410, and a first connection structure 421 is disposed on the second end plate 420; the second connection structure 511 is provided at a first end of the second member 500 to be engaged with the first connection structure 411 of the first end plate 410 and the first connection structure 421 of the second end plate 420.
In one embodiment, the first connection structures 411, 421 and the second connection structure 511 are riveted.
In one embodiment, the gap 430 is filled by the plastic member.
The middle frame member of the present disclosure is applied to a mobile terminal device, for example, a mobile phone, in the vicinity of an antenna of the mobile phone, a gap 430 for radiating electromagnetic waves is provided, the gap 430 can be observed from the appearance, and external dust can enter the mobile phone through the gap 430, for the sake of beauty and dust prevention, the gap 430 is filled with a plastic member, so that the appearance is beautified, the dust prevention effect is effectively achieved, and the strength of the middle frame structure is enhanced.
In one embodiment, the second member 500 is an aluminum alloy plate.
According to another aspect of the embodiments of the present disclosure, a mobile terminal is provided, where the mobile terminal includes a power supply and a middle frame structure, where the middle frame structure is the above middle frame structure, and an electronic component electrically connected to the power supply is disposed on the middle frame structure; and the display screen at least covers the front side and the left and right sides of the second component. Because the display screen of the mobile terminal in the embodiment at least covers the front side and the left side and the right side of the second part, the mobile terminal does not have a left frame and a right frame, and the requirements for the upper frame and the lower frame are improved, so that the strength of the frames is improved by adopting the upper end piece and the lower end piece of the left middle frame and the right middle frame of the titanium alloy plate.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
