Description

Angle detection

Technical field

The utility model relates to a kind of angle detection.

Background technology

Angle detection has been applied on each electron-like (electrical equipment) product widely, such as: products such as warm braw fan, electric heater, in order to control described electron-like (electrical equipment) product when tilting, export a control signal automatically, to control the state that opens or closes of described electronic product.For example: when some electronics (electrical equipment) product was worked in heeling condition, easily the life-span to its part impacted, even the danger that can not expect takes place, and therefore, angle detection has value on its industry for electronic product.

But since existing angle detection, the employing mechanical structure that has, it is to utilize hard contact to finish the action of Push And Release, the work of described action mostly is big Current Control, so that is easy to generate spark oxidation contact, causes phenomenons such as loose contact.Also there is existing angle detection to adopt a level control switch, the mercury (mercury) with conductivity is injected in utilization in a closed container, and be provided with a contact electrode at the sidewall of described closed container, when run-off the straight, mercury in the described closed container will cover described contact electrode, cause short circuit and cut off the electricity supply, avoid electronics (electrical equipment) product under heeling condition, to work on and bad influence takes place.

The angle detection of aforementioned existing machinery formula because of being easy to generate spark, obviously has the doubt on the safety.And the angle detection that adopts mercury to control because of mercury is a kind of highly polluted noxious substance, does not meet the market demand of being particular about Green Product now.Therefore, the angle detection that a kind of innovation must be provided is arranged just, in order to improve aforesaid disappearance.

Summary of the invention

The purpose of this utility model is to provide a kind of angle detection, can be widely used on each electron-like (electrical equipment) product, when the run-off the straight of electronics (electrical equipment) product, can cut off the electricity supply automatically or send warning signal, to improve the fail safe that electronic product uses.

For reaching above-mentioned purpose, the utility model angle detection includes: a detector body, and inside is formed with an accommodation space, and described accommodation space includes alcove, and described alcove down is to be funnel-form; One detecing element group, include a radiated element and a receiving element, wherein, described radiated element is in order to launch one first signal, described first signal is the accommodation space that passes the aforesaid detector body, and described receiving element is in order to accept first signal that described radiated element is launched; With a ball, be to be installed with in the accommodation space of described detector body, when static, described ball is the following alcove bottom centre position that rests on described accommodation space; So, when the detector body tilts to cause ball to roll to leave the residing position of original inactive state, and when allowing receiving element receive first signal that radiated element launches, an exportable secondary signal is as the usefulness of control.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: to improve to have now and utilized mechanical type inclination sensing structure to be easy to generate spark oxidation contact, and cause the use of loose contact to lack, also improved and used the mercury tilt detection to have the environmental issue of high pollution.

Embodiment

Seeing also Fig. 1, Fig. 2, is to show the cut-away view of the angle detection that preferred embodiment is drawn according to the utility model and the three-dimensional exploded view of detector body thereof, includes:

One detector body is to be mutually combined to fix by two housings to form, and includes a upper shell 2 and a lower house 4.Wherein, described upper shell 2 and described lower house 4 are respectively arranged with on one alcove 6 and alcove 8 once, the described alcove 6 of going up is funnel-form respectively with described alcove 8 down, form certain included angle α 1 and α 2 between described funnelform wall gradient and the horizontal plane respectively, and the angle of α 1 equals the angle of α 2.By combining of aforementioned upper shell 2 and lower house 4, utilize that alcove 6 forms an accommodation space 10 jointly with following alcove 8 on it.

One detecing element group, include a radiated element 12 and a receiving element 14, wherein, described radiated element 12 is electrically connected with one first pin 16, in order to launch one first signal (as infrared signal), described first signal is the accommodation space 10 that passes the aforesaid detector body.In the present embodiment, described first signal is to be good with the center of passing accommodation space 10.And described receiving element 14 is electrically connected with one second pin 18, in order to accept first signal that described radiated element 12 is launched.

One ball 20 is to be installed with in the accommodation space 10 of described detector body, and when described detector body not under the normal condition of run-off the straight, described ball 20 is to remain static, and rests on the bottom centre position of the following alcove 8 of lower house 4.Therefore, when static, can utilize ball 20 to cover first signal that described radiated element 12 is launched, when making receiving element 14 not receive first signal that described radiated element 12 launched, cause the state that described detector body is in the operate as normal conducting.When the inclination of detector body caused ball 20 rollings to leave the residing position of original inactive state above a special angle, described receiving element 14 can receive first signal that radiated element 12 is launched, and exports a secondary signal, as the usefulness of control.
