Abstract
The utility model relates to a device for hanging a key ring, which is provided with an inner cavity, wherein a direct current motor and a switching circuit are arranged in the inner cavity; an eccentric vibrating block is installed on an output shaft of the direct current motor, and the circuit of the direct current motor is switched on or switched off by the switching circuit; the switching circuit is composed of a signal receiving circuit, a signal amplifying circuit, a switching pulse signal forming circuit, a triggering-type electric frequency signal circuit and a triode. When a specific wireless signal with high frequency, such as a mobile phone signal, is received, the circuit of the direct current motor is switched on by the triode through the processing work of the circuits, and the eccentric vibrating block rotates to vibrate the device. Therefore, the device becomes a prompting signal source for prompting a carrier to pay attention. In addition, the utility model can also be provided with a sounder and a lamp light circuit, so the prompting signal source is added.
Description
The utility model relates to a kind of key holder pendant.
Key-ring is mixed the effect that a suspension member only plays decoration at present, and obviously, key holder pendant should have more function as a kind of article that often carry.
The purpose of this utility model provides a kind of key holder pendant with reminding effect.
This key holder pendant has the inner chamber of a sealing, be provided with dc motor that eccentric vibration block is housed on the output shaft in the inner chamber and with conducting of dc motor circuit and the on-off circuit that ends, this on-off circuit by the signal receiving circuit that receives high-frequency wireless signals, with signal receiving circuit connect and with signal amplifying signal amplifying circuit, with signal amplification circuit connect and to the trigger-type electricity frequently signal circuit provide the switching pulse signal of pulse signal to form that circuit is connected with trigger-type electricity frequency signal circuit with base stage and the triode that is serially connected in the dc motor circuit is formed.
The key holder pendant of carrying is when receiving a certain specific high-frequency wireless signals, mobile phone signal for example, processing by all circuit, triode is about to the conducting of dc motor circuit, because the effect of eccentric vibration block, key holder pendant produces vibration, thereby remind the carrier to note answering cell phone information, certainly, in the inner chamber of key holder pendant, other alerting signal source can also be set further, as light, sound etc.
Illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: structure chart of the present utility model;
Fig. 2: circuit theory diagrams of the present utility model.
As shown in the figure, described key holder pendant has the inner chamber 1 of a sealing, be provided with dc motor 5 that eccentric vibration block 4 is housed on the output shaft in the inner chamber 1 and with conducting of dc motor circuit and the on-off circuit that ends, this on-off circuit is by the signal receiving circuit that receives high-frequency wireless signals, with the signal receiving circuit connection and with signal amplifying signal amplifying circuit, with signal amplification circuit connect and to the trigger-type electricity frequently signal circuit IC provide the switching pulse signal of pulse signal form circuit and base stage with the trigger-type electricity frequently signal circuit IC be connected and be serially connected in triode Q in the dc motor circuit
4Form.Present embodiment adopts by antenna T, resistance R
1The signal receiving circuit of forming with potential barrier detector diode D, and be the main reception frequency range of setting high-frequency wireless signals with the mobile phone signal; Signal amplification circuit adopts transistor circuit Q
1, switching pulse signal forms circuit and will design according to the requirement of signal circuit frequently of trigger-type electricity, and this enforcement adopts 5208-247 to make trigger-type electricity signal circuit frequently, and it requires just to trigger, and in view of the above, forward and backward two cover transistor circuit Q are adopted in this enforcement
2, Q
3The switching pulse signal of forming output positive triggering pulse signal forms circuit; A whole set of on-off circuit adopts battery E to make power supply, and power switch K is set, and has only when power switch K is closed, and lighter just is in the duty that receives high-frequency wireless signals.In addition, by triode Q
4The functional circuit of conducting except the fast dc motor circuit, acoustics circuit and light circuit can also be set, as other two kinds of alerting signal sources, the acoustics circuit that present embodiment adopts is a telephone bell Chinese percussion instrument W circuit; Light circuit adopts the LED circuit, and certainly, when implementing this programme, inner chamber 1 should be a transparent body, and promptly the housing 6 of key holder pendant is used the transparent material making.
