Abstract
The utility model discloses a good wireless mobile phone, which is used to strengthen the connection between cover metal ground and mean-board metal ground by using the shaft and connect the metal core and shell of the shaft with the main-board metal ground and the cover metal ground respectively. The utility model enhances the connection between the main-board metal ground and the cover metal ground by using the capacitive result between the metal core and the shell, so as to improve the performance, solve the problem that metal ground structure affects wireless performance in a double-cover cellphone, and guarantee the operational performance and the communicative quality.
Description
Technical field
The utility model belongs to the mobile communication terminal technical field, more particularly relates to the designing technique of clamshell handset wireless performance.
Background technology
As a kind of mobile communication terminal device, the wireless performance of mobile phone is vital, and the quality of wireless performance directly has influence on the serviceability and the speech quality of mobile phone.The mobile phone wireless performance not only depends on the design of antenna, also depends on the structure on mobile phone metal ground to a great extent, and the length on metal ground and width can have great influence to the wireless performance of mobile phone.
In the mobile phone exterior design, the flip-shell structure is one of the most frequently used project organization of mobile phone.Large-area metal ground is all arranged in upturning lid of clamshell handset (or down turnover cover) and the motherboard, present technical approach is only to lean on the flexible print circuit board (FPC) of display screen that two metal ground are linked to each other, this connected mode has influenced the length and the width on mobile phone metal ground greatly, thereby seriously influence the wireless performance of mobile phone, especially when talking state (renovate and be in open mode), the wireless performance of mobile phone can be subjected to very big influence, reduce the transmitting power and the receiving sensitivity of mobile phone, thereby had influence on the serviceability and the speech quality of mobile phone.
Summary of the invention
The purpose of this utility model, just be to solve there is influence in the metal ground structure that exists in the present clamshell handset to wireless performance problem, propose a kind of mobile phone that utilizes rotating shaft to improve wireless performance, thereby improved the wireless performance of mobile phone, ensured the serviceability and the speech quality of mobile phone.
In order to solve the metal ground structure that exists in the clamshell handset the problem that influences to wireless performance, the best way is exactly the connection of strengthening renovating between metal ground and the mainboard metal ground, and the utility model utilizes rotating shaft to strengthen renovating connection between metal ground and the mainboard metal ground just.
Improve the mobile phone of wireless performance index, comprise mainboard metal ground, renovate metal ground and rotating shaft, rotating shaft metal-cored with renovate metal ground and be connected, the metal shell of rotating shaft links to each other with mainboard metal ground.
Metal-cored by plain conductor with renovate metal ground and be connected.The metal shell of rotating shaft is connected with mainboard metal ground by plain conductor.
Rotating shaft comprises tupelo, is positioned at the rotating shaft core of tupelo inside, fixedly card-bit part, movable card-bit part, spring and outside rotating shaft shell, and rotating shaft core and rotating shaft shell are the electric conductivity good metal.Tupelo and rotating shaft core are fixed in the cellular phone flip, and the rotating shaft shell is fixed in the main frame.
The utility model utilizes the capacity effect between rotating shaft core and the rotating shaft shell, strengthens renovating the connection between metal ground and the mainboard metal ground.Solved the metal ground structure that exists in the clamshell handset problem that influences to wireless performance, the peak response of mobile phone can improve 4DB, and no line sensitivity improves 4DB, has ensured the serviceability and the speech quality of mobile phone better.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram that structure of the present utility model connects;
Fig. 2 is the cut-away view of clamshell handset shaft.
Embodiment
As shown in Figure 1, with the clamshell handset of antenna 4 in the mainboard bottom is example, the flexible print circuit board of renovating between metal ground 1 and the mainboard metal ground 3 by display screen 2 (FPC) of clamshell handset links to each other, but it is not enough that this connection is only arranged, the utility model utilizes rotating shaft to strengthen between the two connection cleverly, employing links to each other by plain conductor or hardware 7 mainboard metal ground 3 with rotating shaft shell 8, will renovate metal ground 1 and link to each other with rotating shaft metal-cored 6 by plain conductor or hardware 5.Just can effectively strengthen renovating the connection between metal ground and the mainboard metal ground by this method.
Utilize Fig. 2 further to introduce the utility model, by shown in Figure 2, rotating shaft is that fixedly card-bit part 4, movable card-bit part 5 and spring 6 are realized activity and screens in utilization.Tupelo 3 and rotating shaft core 1 are one, be fixed in and renovate, and rotating shaft shell 2 is fixed in the main frame, therefore, though rotating shaft core 1 and rotating shaft shell 2 open, closure renovates in the process and can relatively move, but, rotating shaft core 1 and renovate between the metal ground and rotating shaft shell 2 and mainboard metal ground between relative position be changeless, thereby can effectively ensure the reliability of contact.Though it is normally discontiguous between 2 two metalworks of rotating shaft core 1 and rotating shaft shell, but owing to be the coaxial configuration relation between the two, therefore there is capacity effect between the two, for high frequency radio signal, be the equal of conducting, therefore just can effectively strengthen renovating the connection between metal ground and the mainboard metal ground.
Just can effectively improve the wireless performance of clamshell handset by the described method of the utility model, solve the metal ground structure that exists in the clamshell handset the problem that influences, ensure the serviceability and the speech quality of mobile phone wireless performance.
