Detailed description of the invention
Referring to figs. 1 through Fig. 4 (in Fig. 3, the direction of arrow represents the direction that fork swings), a kind of sensor swinging situation for monitoring rocking chair, comprise the hollow housing 1 be installed on rocking chair, at this moment in, for the ease of hollow housing 1 production and processing, as preferred embodiment of the present utility model, described hollow housing 1 is spliced by left shell 11 and right shell body 12 and forms, therefore can by the one-body molded left shell 11 of mode of injection moulding and right shell body 12, finally left shell 11 and right shell body 12 are stitched together, thus the production efficiency of hollow housing 1 can be improved widely, hollow housing 1 adopts left shell 11 and right shell body 12 to splice composition simultaneously, two parts can be split into, so that follow-up, corresponding parts are installed therein, the fork 2 can followed rocking chair and swing together is provided with in the inside of this hollow housing 1, one end of this fork 2 is articulated with on the inwall of housing 1, and the end 20 that freely swings of fork 2 is provided with the magnetic field sources 3 that can produce the line of magnetic induction, the side, end 20 side that freely swings of fork 2 is also provided with the Hall element 4 for monitoring line of magnetic induction change simultaneously, and this Hall element 4 is fixedly installed on hollow housing 1.Here, above-mentioned magnetic field sources 3 can be a permanent magnet, also can be the coil that can produce the line of magnetic induction that is energized, the line of magnetic induction is produced by permanent magnet or coil electricity, thus can monitor by Hall element 4, in the utility model, magnetic field sources 3 is preferably permanent magnet, install simple and convenient, coil can be avoided to connect the subsequent handling of electric lead simultaneously, below be only a kind of preferred embodiment of magnetic field sources 3 in the utility model and do not limit above-mentioned embodiment, because the utility model is by being provided with the fork 2 can followed rocking chair and swing in the inside of hollow housing 1, this fork 2 is provided with magnetic field sources 3, also be provided with Hall element 4 in hollow housing 1 simultaneously, when rocking chair drives fork 2 to swing, magnetic field sources 3 also followed by fork 2 and swings together, when rocking chair amplitude of fluctuation is larger, when frequency is faster, the amplitude of fluctuation of magnetic field sources 3 is also larger, frequency is also faster, otherwise too, magnetic field sources 3 in swing process near or away from Hall element 4, therefore Hall element 4 monitors the line of magnetic induction that magnetic field sources 3 sends and is also constantly changing, by Hall element 4 monitor the line of magnetic induction change can perception rocking chair swing amplitude and frequency, then Hall element 4 passes to control circuit by monitoring the data obtained, be convenient to control circuit adjusts rocking chair swing amplitude and frequency by drive unit, thus make the swing of rocking chair can be more prone to order to baby asleep.
Further, for the ease of the installation of fork 2, one-body molded on the inwall of described hollow housing 1 have a rotating shaft 10, one end of fork 2 is provided with the sleeve pipe 21 of pivot bush unit in this rotating shaft 10, end 20 place that freely swings of fork 2 is also connected with the elastic device 5 that magnetic field sources 3 can be made to aim at Hall element 4 simultaneously, the other end of this elastic device 5 is connected with hollow housing 1, preferably, described elastic device 5 is a spring or Elastic flexible glue block, further preferably, described elastic device 5 is an extension spring, one end of this extension spring is connected with the end 20 that freely swings of fork 2, and the other end of extension spring is connected with hollow housing 1 top be positioned at above the end 20 that freely swings, in the non-oscillatory situation of rocking chair, this magnetic field sources 3 is aimed at Hall element 4 and keeps motionless, when rocking chair swings, fork 2 drives magnetic field sources 3 to swing up and down, now magnetic field sources 3 away from or near Hall element 4, therefore Hall element 4 monitors the change of the line of magnetic induction that magnetic field sources 3 sends and transfers in control circuit by the data of monitoring, control circuit is by transmitting the data analysis of returning to Hall element 4, thus judge the size of rocking chair amplitude of fluctuation and the speed of frequency, then control circuit is again by the amplitude being rocked to applicable baby asleep and the frequency of drive unit adjustment rocking chair.Above-mentioned elastic device 5 is except can for except extension spring, it can also be Compress Spring, when elastic device 5 is Compress Spring, then Compress Spring is arranged at the below of fork 2, namely the upper surface of Compress Spring and the lower surface of fork 2 abut against, and the inwall bottom surface of the lower surface of Compress Spring and hollow body 1 abuts against.Fig. 4 is the circuit diagram of Hall element 4 in the utility model, because Hall element 4 is known techniques of this area, describes in detail no longer one by one at this.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
