Abstract
A foldable electronic device is composed of shell including the first and the second shell units, installing unit for said shell units, circuit board in shell, and trigger on circuit board to directly couple with a cam integrated to said installing unit.
Description
The present invention relates generally to Foldable electronic device.The present invention is specially adapted to, but is not limited to, and has to monitor the collapsible communicator that this device is positioned at the switch that opens or closes the position.
The Foldable electronic device that is usually used in the communications field comprises two at least by the shell that couples together as the erecting device of folding, for example cell phone, intercom, laptop computer.
Usually, Foldable electronic device has the little shell that is pivotally mounted to big shell, and bigger shell generally comprises most of electronic components.And less shell generally includes earphone or microphone, below is referred to as to renovate.When renovating element by closing out or, need to send out a signal usually and give controller or other parts by reaching when closing, as: close the backlight of LCD (CCD) or stop call automatically.
It is by being installed in the magnetic switch on the shell that a method having opened the index signal of renovating element of closing is provided.Other method sees that the patent No. is 4897873 United States Patent (USP).When having described to open phone, this patent keep two shell elements of phone in the folding apparatus of optimum position.Cam and spring system make the relative position of two case members can be selected.When renovating in off-position, folding can produce the hook state; When renovating when opening, folding can produce out hook-shaped attitude.The hook and the switching of driving hook are finished renovating the control lever of pressing in the switch when closing by the projection of renovating outer surface.Though this folding method provides the switching signal indication, switch still need be loaded in the shell.In addition, need be arranged in the shaft-like piston in the space of contiguous cam, to utilize cam that reciprocating motion is provided or by the piston exciting switch.Unfortunately, because switch must be installed on separately in the shell, above-mentioned prior art needs unnecessary installation steps, therefore, increases set-up time and complexity.
According to the present invention, Foldable electronic device bag Chinese juniper:
Shell has first shell unit and second shell unit at least;
Erecting device, described first shell unit of pivotal mounting is to described second shell unit;
Circuit board is loaded in the described shell; With
Excitation apparatus is installed on the described circuit board, and described excitation apparatus effectively and be directly coupled to the cam that connects with described erecting device.
Better, described erecting device can provide a folding.
Suitably, described folding can have a handle, and described cam is the recess in described handle.
Preferably, described folding can have a handle, and described cam comprises one or more protuberances that stretch from described handle.
Suitably, described handle can form an integral body with described first shell unit.
More satisfactory ground, described handle can be a hollow.
Suitably, described excitation apparatus can be a biased witch.
Preferably, described biased witch can have bossing, is used to control described biased witch.
The present invention can detect wireless telephonic opening and closing with simple and cheap switching device in radio telephone.Consider that from this some switch is chosen the element that the machine of putting is placed on the circuit board with other by tradition and can be installed simultaneously by production line.Therefore, simply by circuit board is installed in the casing, switch just is installed in the wireless telephonic casing naturally.
Be understanding and realization invention, as follows with reference to the accompanying drawing of preferred embodiment:
Fig. 1 is the plane graph at the Foldable electronic device of opening the position;
Fig. 2 is the part of sectional view of amplification of the Foldable electronic device A-A ' along the line of Fig. 1;
Fig. 3 is the plane graph of the Foldable electronic device of off-position;
Fig. 4 is the part of sectional view of amplification of the Foldable electronic device of Fig. 3;
Second embodiment that Fig. 5 describes to invent is described the distortion that cam has extended part.
See figures.1.and.2, describe out the Foldable electronic device of position, usually, Foldable electronic device is a radio telephone 100.Radio telephone 100 comprises two housing sections, first shell unit 113 and renovate second shell unit of 116 forms.In first shell unit 113 circuit board 230 is housed, most of electronic components of radio telephone 100 are installed on the circuit board 230.Folding 120 pivotal mounting are renovated 116 to first shell units 113.Folding 120 has handle 122, and the recess 124 that aligns with the bossing 222 of switch 220 is arranged on the handle.Handle 122 is a hollow.The handle 122 of hollow and first shell unit 113 form an integral body.Folding 120 also comprises the pivot axis 205 that the handle 122 of hollow is provided with first shell unit 113 all-in-one-pieces, first joint 126 and second joint 128, the first joints 126 and second joint 128.
From first end, 250 to second ends 252, the degree of depth of recess 124 increases gradually, and therefore a cam 255 is provided.Switch 220 is installed on the circuit board 230.Switch 220 is directly coupled to handle 120 by bossing 222 by the opening in the shell 113 240, is offset to the switch 220 of opening the position normally usually to control.Therefore, bossing 222 is offset to the cam 255 on the handle 122, and intrinsic effect and direct coupled switch 220 are to cam 255.When renovating 116 when being opened, cam 255 pushes away bossing 222 and enters in the switch 220, with exciting switch 222.
With reference to Fig. 3 and Fig. 4, the radio telephone 100 that is positioned at off-position is shown.Wherein, bossing 222 full extension are in the recess 124 of cam 255.Consequently switch 220 is not activated.
With reference to Fig. 5, describe to can be used for second embodiment of the cam 500 of radio telephone 100.As seen in Fig., cam 500 has a protuberance 505 and is directly coupled to switch element 510 by protuberance 520.Switch is directly coupled to circuit board 530, and wireless telephonic all other elements and wireless telephonic operation are the same with Fig. 1 and Fig. 2 description, no longer repeat.
Though described specific embodiments of the present invention, still can make improvements, protruding as recess.Therefore wish that the claims covering falls within all interior these classes distortion of the spirit and scope of the present invention and improves.
