Description
Technical field
The utility model belongs to a kind of warning device, specifically, relates to a kind of automobile tyre low pressure annunciator.
Background technology
In motor-driven vehicle going, because tire flat causes air pressure to cross low and cause damaged tyres or cause that the phenomenon of another tyre explosion constantly takes place, gently then cause any property loss, heavy then lead to major traffic accidents, thereby automobile driver particularly the automobile driver of long-distance transport need in transit often to stop motor tire is checked, to prevent unexpected the generation.At present, also there is not a kind of comparatively desirable automobile tyre low pressure annunciator to select for use for chaufeur.
Summary of the invention
The purpose of this utility model provides a kind of automobile tyre low pressure annunciator, to solve the defective that lacks desirable automobile tyre low pressure annunciator in the prior art.
The utility model is realized by the following technical solutions: a kind of automobile tyre low pressure annunciator comprises main frame receptor and projector assembly; The main frame receptor is provided with power supply wiring and loudspeaker, and the projector assembly comprises the projector housing; The projector housing is provided with jogger hole and handle hole, and push rod is installed in the jogger hole, and push rod is provided with compression spring, and the push rod end is provided with the reed of moving; Be provided with integrated circuit board, power-supply battery in the projector housing and decide spring leaf, integrated circuit board and power-supply battery are fixed in the projector housing by integrated circuit board mount and power-supply battery support respectively, decide spring leaf and be fixed on jogger hole below, integrated circuit board, power-supply battery and decide to connect by lead between the spring leaf.
Handle hole is provided with and seals.
Compared with prior art, the beneficial effects of the utility model are: use automobile of the present utility model, in case the air pressure of certain tire of automobile is lower than the standard that annunciator is set in the way of advancing, chaufeur can in time be learned in operator's compartment, and can in time stop relevant tire is handled, can avoid contingency to take place effectively, thereby avoid economic loss and personal casualty.
