Abstract

A sensing device includes a housing, a transmitter accommodated on one side of the housing, a receiver accommodated on the other side of the housing, and a transparent conductor. The conductor is rotatably accommodated in the housing and is located between the transmitter and the receiver. Thus, when the light beam emitted by the transmitter is directed toward the rolling conductor, refraction and polarization phenomena will occur, so that the receiver receives light beam signals of different strengths, and then generates different action modes according to the different changes in the signal strength.

Description

Sensing device

technical field

The invention relates to a sensing device, in particular to a sensing device capable of generating light beam signals with different strengths.

Background technique

Referring to FIG. 1 , taking a common ball switch 1 as an example, it mainly includes a body 11 , two sets of pins 12 , 13 and a ball 14 . The body 11 has a hollow chamber 111 . The pins 12 , 13 respectively have one end 121 , 131 passing through the chamber 111 , and the other end 122 , 132 passing through the body 11 . The ball 14 is rotatably accommodated in the chamber 111 of the body 11 . In this way, when the ball switch 1 is vibrated by an external force, and the ball N rolls between the two sets of pins 12, 13 and contacts with one end 121, 131 of the pins 12, 13 at the same time, the circuit can be turned on, so that The ball switch 1 is in the ON state. Conversely, when the ball 14 is separated from one end 121 , 131 of one set of pins 12 , 1 , the circuit will be blocked and the ball switch 1 will be in the OFF state. However, although the above-mentioned device can achieve the purpose of switching the ON/OFF state by vibration, it still has the following deficiencies in actual use, which need to be solved urgently:

1. Since the ball 14 and pins 12 and 13 must be made of metal to conduct current, the ball 14 and pins 12 and 13 made of metal will inevitably produce gasification, especially in places with heavy humidity. Therefore, after the ball switch 1 is used for a period of time, poor contact and signal transmission failure will occur.

2. In terms of action tense, the general ball switch 1 only has ON/OFF changes, which obviously cannot meet the needs of various tense changes in today's electronic products.

Detailed ways

As shown in FIG. 2 and FIG. 3 , the sensing device of the present invention includes a housing 2 , a transmitter 3 , a receiver 4 , a package 5 and a conductor 6 .

The shell seat 2 is divided into a main chamber 21 located in the middle, a first side chamber 22 and a second side chamber 23 located on both sides of the main chamber 21, and two chambers communicating with the main chamber 21 and the first chamber respectively. , The gaps 24, 25 of the second side chambers 22, 23.

The emitter 3 is inserted in the first side chamber 22 of the housing base 2 , and has an emitting point 31 capable of emitting light beams and protruding from the gap 24 , and a set of pins 32 passing through the housing base 2 .

The receiver 4 is inserted in the second side chamber 23 of the case base 2 , and has a receiving point 41 protruding from the notch 25 for receiving light beams, and a set of pins 42 passing through the case base 2 .

The packaging body 5 is accommodated in the main chamber 21 of the housing base 1 , and has two closed covers 51 , 52 that fit together and a rolling space 53 defined between the closed covers 51 , 52 . Each cover 51 , 52 respectively has perforations 511 , 521 (refer to FIG. 4 ) which are opposite to the transmitting 31 of the transmitter 3 and the receiving point 41 of the receiver 4 and pass through the rolling space 53 . The shape of the rolling space 53 can be varied according to various demands.

The conductive body 6 is a transparent spherical body, which is rotatably accommodated in the rolling space 53 of the package body 5 , and is located between the transmitter 3 and the receiver 4 .

Referring to Fig. 4, when the present invention is oscillated by an external force, the conductive body 6 will roll in the rolling space 53 of the package body 5, thereby, when the emitting point 31 of the emitter 3 emits a beam, the beam will travel along a straight line and pass through. Through the perforation 511 of the package body 5, it shoots towards the rolling conductor 6. At this time, the rolling conductor 6 will have different angle changes relative to the emission point 31, so that refraction and polarization will occur when the light beam passes through the conductor 6, and the Only part of the refracted or polarized light beam will be emitted from the through hole 521 of the package body 5 , and other light beams will be scattered in the package body 5 , so that the receiving point 41 of the receiver 4 receives light beam signals of different strengths.

According to the above, when the receiving point 41 of the receiver 4 continues to receive the light beam signal with the same strength, it can be set to OFF state, and when the receiver 4 receives the light beam signal with different strength, it can be set to ON state, and can generate different action signals according to the strength and weakness of the beam signal. In this way, the present invention can control the electronic devices matched with each other to make the electronic devices produce different action modes.

In addition, the conductor of the present invention can also be a polygonal body, such as the hexagonal conductor 7 shown in Figure 5, except that it can be a sphere. Angle change causes refraction and polarization when the light beam passes through the conductive body 7, and only part of the refracted or deflected light beam will be emitted from the through hole 521 of the package body 5, while other light beams will be scattered in the package body 5, making the receiver 4 The receiving point 41 receives beam signals with different strengths.
