Abstract

The utility model relates to a two-way angular displacement switch, which comprises an angular displacement arranging rack, an oscillating axle, a positive electrode, a reverse electrode, a handle and an arc board. The working principle is that the angular displacement arranging rack is arranged on the axle base in need of the control device through the two ends of the oscillating axle; when the device rotates clockwise, the oscillating axle is communicated with the positive electrode; when the device rotates counterclockwise, the oscillating axle is communicated with the reverse electrode and the circuit undergoes change. The two-way angular displacement switch is used to the oscillating axle of the anti-myopia prompting device. When communicated with the positive electrode, the switch is communicated with the RC charge circuit and triggers the prompting device through time delay and the useless prompt is filtered off. When communicated with the reverse electrode, the switch is communicated with the RC discharge circuit and releases the charged load in preparation for triggering the prompting device through time delay next time.

Description

A kind of two-way angular displacement switch

This use is novel to belong to switch motion when the angle of object and plumb line reaches certain angle in the certain angle scope, the switch of angle initialization and angle identification just.

Now disclosed Sitting posture correcting device angle sensor element generally adopts the mercury sensing element, as 93247912.X and No. 93202588.9 Patent publish.Also having a kind of is metal pendulum mass angular displacement touch switch, as No. 002151316 Patent publish.The former is because of using mercury, as large-scale popularization, serious environment pollution after spending the several years, handle rotation place that the latter corrects the reminiscences shell because of sitting posture has big opening influence attractive in appearance and advance the poor stability that foreign matter makes the angular displacement switch easily, also have a significant drawbacks to be: to turn one's head suddenly unavoidably when using reminiscences, stand, head moment is leaned forward translation, playing the mercury or the pendulum mass of the effect of conduction medium this moment makes, causes noise to make the user vexed because of making switch closure useless prompting occur by its inertia.

The utility model is for a kind of two-way angular displacement switch that provides is provided.

A kind of two-way angular displacement switch, it comprises the angular displacement fixed support, balance staff, pendulum mass is provided with forward electrode and reverse electrode in pendulum mass two sides on the angular displacement fixed support.

At angular displacement fixed support reverse electrode handle is set laterally.

The camber plate is set between angular displacement fixed support reverse electrode and handle.

The angular displacement fixed support adopts the closed loop frame, and place, the middle balance staff of this closed loop frame hole is provided with outstanding to the inside along the balance staff direction, on this is outstanding circular hole is set, and this circular hole axle is coaxial with the balance staff hole.

Pendulum mass and forward electrode are in critical contact condition when pendulum mass is in the vertical state, and pendulum mass and reverse electrode are separated.

The angular displacement fixed support adopts the open loop frame, and place, the middle balance staff of this closed loop frame hole is provided with outstanding to the inside along the balance staff direction, and this gives prominence to circular hole is set, and this circular hole axle is coaxial with the balance staff hole.

In the balance staff termination balance staff head is set, on spindle nose, has translot.

Described forward electrode and reverse electrode are conduction bar type or conduction chip or power spring chip.

Further specify the utility model below by the embodiment drawings and Examples.

Angular displacement fixed support in the present embodiment, arc 6, but handle 5 single injection-moldeds, balance staff 1, pendulum mass 2, forward electrode 3, reverse electrode 4 is made by machine work and punch forming.

One of them balance staff 1 directly welds out the lead-in wire practical operation from balance staff 1 and has any problem because of very thin in three electrodes of this two-way angular displacement switch, so open translot 12 at balance staff head 11, putting lead-in wire at translot 12 welds out, in addition two electrode forward electrodes 3, reverse electrode 4, these two electrode areas more directly weld out electrode wires and get final product.

Balance staff 1 two ends of this two-way angular displacement switch are contained on the axle bed that needs control device, and make handle 5 and need control device closely to contact (being contained in reminiscences shell axle bed when being used for reminiscences) to make enough frictional resistances are arranged between them.During use reminiscences is worn on the ear, right overhead or waist turn forward, the relative pendulum mass 2 of angular displacement fixed support turns clockwise, pendulum mass 2 contacts with forward electrode 3 balance staff 1 and forward electrode 3 is connected by pendulum mass 2, this moment, power supply E began charging (as Fig. 5) by resistance R to capacitor C, fill that electric capacity two terminal voltages are enough to trigger reminiscences after 1～2 second, come back this moment or straight waist pendulum mass 2 and forward electrode 3 disconnect connecting with reverse electrode 4 electricity that has filled is bled off by resistance R again.So moment, kinetic switch closure less than 1～2 second was all invalid, had filtered most of useless prompting, had reduced noise.
