Abstract
The utility model relates to a sensor for a tyre pressure monitoring device, which comprises an electronic circuit and a power supply for providing electricity for the electronic circuit. The utility model is characterized in that a motion detection switch is connected in series between the electronic circuit and the power supply, wherein, when the motion detection switch is in a static state, the motion detection switch switches off, and the motion detection switch switches on when reached a certain velocity of movement. The utility model can open and close the power supply without manual work, and the utility model has the advantages of electricity saving, and convenience.
Description
The utility model relates to a kind of sensor of tire pressure monitoring device.
No. 4734674 patents that the U.S. announced on March 29th, 1, No. 5289161 patents that on February 22nd, 1 announced, No. 5694111 patents of announcing on December 2nd, 1 disclose the sensor of tire pressure monitoring device respectively, the sensor of these existing tire pressure monitoring devices comprises to be had electronic circuit and is the power supply of electronic circuit power supply, its common feature is electronic circuit and power supply direct connection, this just makes no matter whether need to monitor tire pressure, power supply is all in running order, cause consumption of current big, battery altering is frequent, not only wastes energy but also uses inconvenience.
The purpose of this utility model is to provide a kind of sensor of saving the tire pressure monitoring device of power supply consumption of current.
The utility model is realized in the following way: the sensor of tire pressure monitoring device comprises to be had electronic circuit and is the power supply of electronic circuit power supply, between electronic circuit and power supply, be serially connected with when static and disconnect, reach closed motion detection switch after the certain movement speed.After adopting said structure, have only when sensor rotates with wheel, power supply is just powered to electronic circuit by the motion detection switch, and when wheel stops operating, the motion detection switch disconnects, and the power supply power consumption is zero, thereby has compared with the prior art saved the power supply consumption of current greatly.
The utility model has the advantages that to need not manually to open and close power supply, not only power saving but also convenient.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, the sensor of tire pressure monitoring device comprises to be had electronic circuit and is the power supply of electronic circuit power supply, is serially connected with motion detection switch 1 between the two at this.Motion detection switch 1 can be selected for use in existing various motion detection switches, as CG1001-1 type motion detection switch produced in USA.Whole sensor is with wheel when vehicle ', when vehicle ' reaches certain speed after motion detection switch 1 closure, power supply is powered to electronic circuit, normal operation of sensor; Wheel is static when stopping, and motion detection switch 1 disconnects cuts off the electricity supply, thereby has saved the power supply consumption of current.
Claims (1)
1, a kind of sensor of tire pressure monitoring device includes electronic circuit and is the power supply of electronic circuit power supply, it is characterized in that: at the electronics line slightly and also be serially connected with between the power supply and disconnect when static, reach closed motion detection switch 1 after the certain movement speed.
