Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation of the utility model mobile terminal device embodiment, Fig. 2 is that the A-A of Fig. 1 is to cutaway view, Fig. 3 is the partial schematic diagram in B zone among Fig. 2, Fig. 4 is the structural representation one of button cap among the utility model mobile terminal device embodiment, and Fig. 5 is the structural representation two of button cap among the utility model mobile terminal device embodiment.As Fig. 1-shown in Figure 5, the present embodiment mobile terminal device comprises shell 1 and is wrapped in circuit board 2 in the shell 1, also comprises button 3.
Particularly, button cap 31 in the present embodiment is provided with ledge structure 311 with the end that key switch 32 leans, after button cap 31 is inserted in the key hole 11 of shell 1, ledge structure 311 will increase the gap between button cap 31 and the key hole 11, thereby the burr that effectively reduces key hole 11 places hinders the generation of the phenomenon of button cap 31 slips, makes the user can press button cap 31 smoothly; And,, effectively reduced the possibility that button cap 31 can't reset pressing back being blocked by burr because the gap between button cap 31 and the key hole 11 is bigger.Wherein, the performance entity of present embodiment mobile terminal device can be portable electric appts such as mobile phone, net book or MP3, and the present embodiment mobile terminal device does not limit its performance entity; In addition, button 3 can be provided with on the sidewall of present embodiment mobile terminal device, also can be arranged on the front of present embodiment mobile terminal device.
The present embodiment mobile terminal device, by the end that button cap and key switch are leant ledge structure is set, end and the gap key hole of shell between of button cap in shell increased, reduce the possibility that the burr of button cap and shell comes in contact, thereby in the button cap moving process, effectively alleviate burr on the shell to the inhibition of button cap, improved the handling of button in the mobile terminal device.
Based on technique scheme, optionally, in order to make being plugged in the shell 1 that button cap 31 can be firm, avoid button cap 31 in use from shell 1, to detach, button cap 31 in the present embodiment also comprises flap 313, and flap 313 is fixedly arranged on the end of ledge structure 311 in the button cap 31 and stretches out perpendicular to ledge structure 311.
Particularly, button cap 31 in the present embodiment has flap 313, thereby when button cap 31 is worn behind the outside by key hole 11 by the inside of shell 1, flap 313 can be resisted against on the inwall of shell 1, thereby can prevent that button cap 31 from detaching from the key hole 11 of shell 1.
Further, can slide in the key hole 11 of shell 1 stably in order to make button cap 31, ledge structure 311 can be installed with many positioning bars 312 that are used to be resisted against on the key hole 11.Concrete, the outer surface of the ledge structure 311 in the present embodiment is provided with many positioning bars 312, after being inserted into button cap 31 in the key hole 11, positioning bar 312 will be resisted against on the hole wall of key hole 11, thereby button cap 31 can be lived by key hole 11 effective support, button cap 31 can be slided in key hole 11 more stably.Wherein, in the present embodiment positioning bar 312 can with the moving direction place straight line parallel of button cap 31, thereby can effectively reduce frictional force between positioning bar 312 and key hole 11 hole walls, button cap 31 can be slided in key hole 11 smoothly.
The present embodiment mobile terminal device is provided with flap by the end at ledge structure, and flap can be resisted against after button cap resets on the inwall of shell, has effectively avoided button cap to detach from key hole.By on the outer surface of ledge structure, positioning bar being set, positioning bar will be resisted against on the hole wall of key hole, thereby button cap can be lived by the key hole effective support, button cap can be slided in key hole more stably, thereby make the feel of button better.
Based on technique scheme, optionally, can automatically reset and improve the feel of button 3 in order to make button cap 31, the button 3 in the present embodiment also comprises silicagel pad 33, silicagel pad 33 is between button cap 31 and key switch 32.
Same, the button in the present embodiment can also comprise spring (not shown); One end of spring is resisted against on the button cap 31, and the other end is resisted against on the key switch 32.
Particularly, the button in the present embodiment 3 can realize that button cap 31 can automatically reset by silicagel pad 33 or spring.The present embodiment mobile terminal device is that example describes with silicagel pad 33.After between button cap 31 and the key switch 32 silicagel pad 33 being set, after the user presses button cap 31, button cap 31 will push silicagel pad 33, by silicagel pad 33 key switch 32 is pressed connection then, after the user looses one's grip, silicagel pad 33 can resile automatically, thereby button cap 31 is resetted.And owing to be provided with silicagel pad 33 between button cap 31 and the key switch 32, make between button cap 31 and the key switch 32 and have certain pretightning force, thereby press in the process of button cap 31 the user, the sensation that button cap 31 degrees of tightness differ can not occur, thereby make the feel of button 3 better.
The present embodiment mobile terminal device by silicagel pad or spring are set between button cap and key switch, can make button cap automatically reset after pressing; And make by silicagel pad or spring to have certain pretightning force between button cap and the key switch, thereby press in the process of button cap, the sensation that the button cap degree of tightness differs can not occur, thereby make the feel of button better the user.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
