Description

The automatic cover-turning mobile phone

Affiliated technical field

The utility model relates to a kind of clamshell phone.

Background technology

Along with people's the growth in the living standard and the development of mechanics of communication, mobile phone has become the product of our indispensability.On the market, the function of mobile phone and style are abundant further, not only satisfy the needs of people in communication, have also become the thing of the carry-on decoration fashion of people.

Clamshell phone in the market, no matter be upturning lid or down turnover cover, though all evenly be type hand. having to be designed to spring from opening, yet need the built-in spring of manual compression when closure, the both hands cooperation, is not very convenient.

Summary of the invention

The utility model provides and a kind ofly utilizes automatically turning over that built-in motor drives to close mobile phone. and both can open certainly, can close certainly again.Both made things convenient for, again fashion.

For realizing above purpose, the design of the utility model is by built-in motor; Drive gear mechanism and electric machinery control device are formed.Built-in motor should be a DC micromotor.As mobile phone is the vibrating motor vibrating alert, also can utilize it as power.So must design clutch for it, vibrating alert and mobile phone be turned over close irrelevant mutually.

Drive gear mechanism is designed to the worm and gear transmission, utilizes its gearratio big, steady and its self-locking performance., consider that the gearratio of renovating with motor is bigger, can design the gear drive of 1-2 level again.Transmission mechanism adopts micromachine transmission and motor to can be made into one, is convenient to install and the decline cost.

Electric machine control system is designed to logic control circuit.Trigger manual and stroke contact by mobile phone, gives motor by logic control and by the voltage control system output voltage.Be designed to the voltage output more than 2 grades, make motor that speed more than 2 kinds be arranged, thereby the time that cellular phone flip is turned over close is adjustable, or realize the differential clutch.Voltage control system also has been designed to positive negative sense voltage output.More than design all should be adopted the large scale integrated circuit module that adapts to mobile phone.

Adopt design of the present utility model, the use of mobile phone one hand is fully carried out fast, has embodied convenience; Fast; Fashion.Be fit to the modern life, handle official business people; During driving, as long as one press gently, the open and close that she just can be at the uniform velocity.Make the more fashion and the hommization of use of mobile phone.

Operating process below in conjunction with the drawings and specific embodiments is described in further detail utility model.

First embodiment

U is and door among Fig. 3, and V is a not gate.Logic D=B*X; (following * be with ,+for or, for non-) E=X*C; F=D*J; G=D*J; H=E*J; I=E*J.J connects mobile phone master controller, the setting that its level can be artificial (following J=1 is an example).T is a toggle flip-flop, and its operation principle is: when A point input pulse, and the upset of X end level.Be X (n+1)=X (n), effective during the CP low level.I, g and h, f and peripheral circuits form multiplication factor circuit (it is bigger than i, g multiplication factor to establish h, f) inequality among Fig. 4.E, d are conduction pipes.

When mobile phone is in closed holding state, the closed B=1 in contact (6) (following high level is 1, low level be 0); C=0 is opened in contact (3); Contact (4) end by the T trigger for just cheating state, X=0.So D, E=0, F, G, H, I=0, among Fig. 4, motor is static.When using mobile phone, press lower contact (4), at high level of A pin input, the CP low level is effective, and T trigger upset X=1 C=0 this moment makes E=1.During J=1, H=1, F, G, I are 0 in addition.H, e plumber do among Fig. 4, and because of the h multiplication factor is big, motor forward higher speed rotates, and among Fig. 2, motor is driven gear (10), (9) and worm and gear (7), (8) successively, drive and cover arbor wheel (2), and mobile phone begins to open.

When touching stroke contact (3), C pin input high level, among Fig. 3, E=0 during C=1, H=0 F, G, I in addition are 0.Motor stops, worm and gear self-locking among Fig. 2, renovate among Fig. 1 (1) static.Stay open.

In like manner, when touching (4) again, the T X=0 that overturns, because of mobile phone open, when B does not touch B=0, D=1, F=1 during J=1, H, G, I are 0 in addition.F, d work among Fig. 4.The reverse higher speed counter-rotating of motor drives transmission mechanism, and mobile phone begins closure.

When touching stroke contact (6), B=1, D=0, F=0, H, G, I are 0 in addition.Motor stops, and the closed self-locking of mobile phone is got back to closed holding state, so repeatedly.

In addition, manual contact (4) should be designed to invaginating or to contact (4) append the present mobile phone of design imitate the length that adopt more by self-locking, explain by oneself.In case mobile phone is arbitrarily opened.Therefore the class technology is a known technology, does not repeat them here.

Second embodiment

The former the design's built-in motor of some mobile phone is used for the vibrating alert function, and the utility model second embodiment utilizes its turning over automatically of mobile phone of realization to close.Its logical circuit is identical with a last embodiment with the amplifying circuit basic principle, as Fig. 7, Fig. 8.The J point was that the people is the control point originally, called out control for extraneous signal in a second embodiment.Among Fig. 7 when no extraneous signal is called out, J=0, D, E level are in the contact (2); (4); (6) under the control, logic, amplification operation principle and first embodiment are similar, and among Fig. 8, when D or E were high level, motor was even for running up.Known automatic clutch mechanism is more, and the utility model adopts centrifugal clutch, among Fig. 6, during high speed, clutch driving wheel (14) high speed rotating drives external gear (13) and rotates and drive transmission mechanism in the race outside centrifugal bar (18) is located under centrifugal action, as Fig. 5, mobile phone is turned over close.There is extraneous signal to call out J=1, contact (2); (4); (6) do not work.Among Fig. 8, the D point voltage during than J=0 D be 1 o'clock low, the motor low-speed running, centrifugal bar (18) is in interior wheel among Fig. 6 under the effect of spring (17) and friction, clutch drives internal gear (15) and rotates, and drives vibrating mass (16), causes vibration.
