Embodiment
The invention provides integrally formed covering body and keypad, and give elastic acting force for covering body and keypad, make the front cover of a kind of mobile communication terminal of pressing operation.
With reference to the accompanying drawings the embodiment among the present invention is described in detail.
In the process that the embodiment among the present invention is described, identical structure will be given identical drawing symbol in each accompanying drawing.
Fig. 4 is the stereogram of the mobile communication terminal among the present invention; Fig. 5 is the stereogram of the front cover of the mobile communication terminal among the present invention; Fig. 6 is the B-B line sectional view among Fig. 5.
To shown in Figure 6, the mobile communication terminal 50 among the present invention includes as Fig. 4: the front cover 60 and the back cover 70 that form the outward appearance of mobile communication terminal 50.Wherein, between front cover 60 and the back cover 70 printed circuit board (PCB) is installed, above-mentioned printed circuit board (PCB) is provided with the various electronic components (not shown) that are used for mobile communication terminal.
Include the covering body 62 that is incorporated into back cover 70 in the front cover 60, the image display part 80 that is used for the image video data is installed on the above-mentioned covering body 62.
Wherein, image display part 80 is connected with above-mentioned printed circuit board (PCB), and the display surface of its show image information exposes to the outside.For this reason, be formed with breakthrough part 63 on the covering body 62, thereby can externally see image display part 80.Simultaneously, in the breakthrough part 63 face glass is installed, makes the information (not shown) that externally to confirm demonstration in the image display part 80.
And the top of image display part 80 is provided with the 62a of receiver portion that is used for electronic signal is converted to voice signal, hides body 62 bottoms and is provided with then that to be used for the user's voice conversion of signals be the microphone portion 62b of electronic signal.
In addition, hide the integrally formed keypad 66 that is useful on input user's input information of a side of body 62.
Wherein, keypad 66 is constituted by a plurality of keys 67 of representing literal or numeral etc., the back of key 67 is formed with knob 68, the splicing ear that forms on contact 68 and the above-mentioned printed circuit board (PCB) contacts, make when the user presses keypad 66, contact 68 will be pushed the splicing ear of above-mentioned printed circuit board (PCB) and generate electronic signal.
Here, front cover 60 is made of the elastic material that comprises rubber composition or urethanes composition, thus make hide body 62 is connected with keypad 66 elasticity and make keypad 66 carry out about pressing operation.
And,, hide between body 62 and the keypad 66 and be formed with rib 69 for making moving of keypad 66 more flexible.Rib 69 compares covering body 62 or keypad 66 has thin thickness, hides the elastic force between body 62 and the keypad 66 and makes button operation more flexible thereby improve.
Simultaneously, rib 69 is to form across the direction complications that hide between body 62 and the keypad 66.In an embodiment of the present invention, rib 69 tortuous formation of direction depression of pushing with keypad 66.Certainly, the direction that rib 69 is pushed with keypad 66 is protruded tortuous formation.
Thus, by the rib 69 tortuous structures that form, when button 66 was pressed, the distortion of rib 69 obtained buffering and keypad 66 is descended.
Below the as above effect of the front cover of the mobile communication terminal of structure is described.
Utilize the mobile communication terminal information such as input digit or input characters of making a phone call for making, the user will press the keypad 66 of the front cover 60 of mobile communication terminal.Wherein, keypad 66 is integrally formed with covering body 62, and the key 67 of keypad 66 will move down under the effect of the rib 69 that elasticity connects.
Thus, when the key 67 of keypad 66 moved down, the contact 68 that the bottom of key 67 forms will be by the splicing ear of pressing printed circuit board, thereby imports information such as required numeral, literal.
Then, the keypad 67 of input information will move up and turn back to original position under the effect of the restoring force of rib 69.
Thus,, can reduce the thickness of front cover 60 and save Master Cost by hiding the integrative-structure of body 62 and keypad 66, need not simultaneously to carry out separately assembly manipulation and to its management.
And, do not have the slit owing to hide between body 62 and the keypad 66, thereby can prevent that foreign substances such as dust or water from flowing into the inside of mobile communication terminal.
Abovely be illustrated with reference to the front cover of accompanying drawing to the mobile communication terminal among the present invention, but the present invention is not confined to aforesaid embodiment, in the category that does not exceed basic fundamental thought of the present invention, the operator of relevant industries can carry out various deformation and application to it.
