Abstract

The utility model discloses a portable retractable mobile phone, comprising a displaying part and a retractable digital keyboard. A cavity for holding the digital keyboard is arranged in an inner case of a displaying case. Each side of the cavity is provided with a track for vertical motion of the digital keyboard. An abnormal shape of joint points for ensuring the digital keyboard inserts into the displaying part are arranged on the inner case of displaying part as well as the both sides of the external case of digital keyboard. Because the inner displaying part is provided with the cavity for holding the digital keyboard which have tracks on both sides of the cavity, the digital keyboard inside the displaying part may extend freely along the track, thus shortened the length of the cell-phone, reduced the volume of the cell-phone and very easy to be carried about.

Description

A kind of portable extension type mobile phone

The utility model relates to a kind of mobile phone, refers to a kind of portable extension type mobile phone especially.

Along with the development of communication career, the owning rate per capita of mobile phone is more and more higher, and mobile phone no longer is some a few people's a patented product.But, make a general survey of the mobile phone profile on the market, kind is single, and volume ratio is bigger, and inconvenience is carried.

In view of the foregoing, it is little that the purpose of this utility model provides a kind of volume, scalable, easy to carry, the mobile phone of flexible operation.

For achieving the above object, the utility model adopts following design: a kind of portable extension type mobile phone, and it is made up of display part and telescopic numeric keypad; The display part comprises housing, antenna, receiver, display screen, function keyboard and switch; Upper rear portion in the display part is equipped with battery; It is characterized in that: be provided with a cavity that can hold numeric keypad in described display part enclosure interior, the both sides of described cavity are provided with the track that moves up and down for numeric keypad; Be provided with in housing inboard, the numeric keypad case body both sides of described display part and can make numeric keypad insert in the display part and the abnormal shape that can slide up and down is refuted and connect bayonet socket; Circuit board in the described display part links to each other by lead with circuit board in the numeric keypad.

The switch of described display part is made up of the slide bar and the spring of a band grab; Corresponding with the hook on the slide bar, on described numeric keypad, have a groove.Be respectively equipped with a columned gear in the inboard both sides of described numeric keypad near described display part housing, on the concentric shafts of gear, be wound with gear and be concentric spring, be designed to the zigzag track that matches with cylindric gear in described display part housing madial wall and gear contact site.

Because the utility model has a cavity that can hold numeric keypad in the mobile phone display part, design has abnormal shape to refute to connect the driven wheel of bayonet socket and tracks and band clockwork spring on cavity two side bodies, the numeric keypad that is built in the display part can be stretched freely along track, thereby shortened the length of mobile phone, reduced the volume of mobile phone, carried more convenient.And under the configuration state, function keyboard and display all design at the mobile phone surface location in numeric keypad is in, and still can browse the most of function of incoming call and compounding practice, use more flexible.

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1-shown in Figure 5, the utility model is made up of display part 1 and telescopic numeric keypad 2.Display part 1 comprises housing 11, antenna 12, receiver 13, display screen 14, function keyboard 15 and switch 16.1 upper rear portion is equipped with battery 3 (as shown in Figure 3) in the display part; Have a cavity 17 (as Fig. 4, shown in Figure 5) that is used to hold numeric keypad in the inside of housing 11.The bottom of numeric keypad 2 is provided with a folding microphone 24.

Fig. 6 is the utility model cross-sectional view, and figure China and foreign countries area shading is the numeric keypad shell for the housing 11 of display part 1, inner dash area partly.Be provided with abnormal shape in inboard, the numeric keypad case body both sides of display part housing 11 and refute and connect bayonet socket, numeric keypad 2 is refuted by abnormal shape connect bayonet socket and insert in the housing of display part and can slide up and down, connect as a whole with the display part.

Again with reference to shown in Figure 7, the abnormal shape that is used to hold cavity 17 both sides of numeric keypad in the display part is refuted to connect and is provided with track 171 in the bayonet socket, and the numeric keypad 2 that inserts in the display part 1 can be moved up and down, and is capable of expansion and contraction.A side of 1 is provided with a switch 16 that is used to lock/discharge numeric keypad 2 in the display part, and switch 16 is made up of the slide bar 161 and the spring 162 of a band grab; Corresponding with the hook on the slide bar 161, on numeric keypad 2, have a groove 21.When needs use numeric keypad 2 dialing, pin switch 16, to deviate from the groove 21 of the grab on the slide bar 161 from the numeric keypad 2, keyboard just can move downward expansion along track 171; When finishing using, with hand keyboard is upwards promoted, make in the cavity 17 of numeric keypad retraction display part, the grab of slide bar 161 is stuck in the groove 21 again, finishes numeric keypad 2 and returns and be locked in process in the cavity 17 of display part.

For the numeric keypad 2 that places in 1 cavity 17 of display part is launched automatically, can numeric keypad 2 inboards, top near the display part housing in 11 both sides be respectively equipped with a columned gear 22, on the concentric shafts of gear 22, be connected with the Mainspring type spring 23 concentric, be designed to the zigzag track that matches with cylindric gear in display part housing 11 madial walls and gear contact site with gear.Like this, when not using numeric keypad 2, when pushing numeric keypad in the display part with hand, columned gear 22 rotations are also passed through the Mainspring type spring 23 of the rich stressed joint of axle on axle, make it to have power.When needs launch keyboard, when Push switch 16 discharged keyboards 2, gear can drive the downward easy motion of keyboard, and keyboard is launched automatically.

Fig. 8, Fig. 9 return for the utility model numeric keypad and schematic perspective view when launching.

Partial sectional perspective view when Figure 10 launches for the utility model.The utility model only improves the mechanical structure of existing mobile phone machine, does not do any improvement for the circuit part of mobile phone inside.Circuit board in the utility model display part links to each other by the Z shape lead 5 in the display part with circuit board in the numeric keypad, carries out signal transmission to each other.

The above only is preferred embodiment of the present utility model, and the equivalent transformation of any basic utility model technical scheme all belongs within the utility model protection range.
