Abstract
The utility model discloses a kind of wear on tyres alarming device, comprise micro-switch and warning device, described micro-switch be connected with warning device with circuit in, described micro-switch is arranged in described tire groove, when wear on tyres is during to catch siding position, tire in rolling process as for described micro-switch, described micro-switch is closed under the bearing capacity effect of ground, circuit is connected, warning device work, the timely changing of tire of prompting car owner.
Description
Technical field
The utility model relates to field of vehicles, particularly the abrasion alarming device of the tire of vehicle.
Background technology
At present, after may wear to some degree after tire used, the rubber that earth-grasping force is responsible for maintaining in top layer can disappear because of wearing and tearing, this time is the remaining hard rubber and the reinforced fibre silk thread that maintain tire pressure and fetalism bearing force of exposing only, now earth-grasping force will decline rapidly, and when tire is in the rainy day time, is to get rid of the ponding on tire by tread, if the person that there is no tread, in the more notable downslide of rainy day earth-grasping force.This has illustrated that tire has its useful life, if tire starts distortion, still at road traveling, it is circular that whole tire can not keep, and under this situation, can cause habitual abortion phenomenon if put brakes on violently, and even blowing out overturns causes severe traffic accidents.The wear on tyres situation of therefore changing tire for understanding this for user, has above tire " catch siding ", while exceeding, should change tire.Tire all can have the catch siding that shows abrasion lowest limit index, and the relief bulk of catch siding position between the groove of tire tread the inside, so the treadwear of working as tire to dressing with catch siding, represents that the life-span of tire will must be changed to the greatest extent.
But common people are difficult to often note the wearing and tearing of tire, while conventionally only having the maintenance prompt of arrival, transfer to maintainer to confirm to check just to know whether to want changing of tire.If but postpone service time, produce tread wear when dressing catch siding state and locate eccentric wear or clash into during empty window, user does not conventionally examine and still travels on road surface, thus, just than the contingency that is easier to habitual abortion occur, blow out, affect my property safety and arround with the safety of car, steerman.Therefore how there is a design of at once pointing out user to note, be still a urgent important topic.
Summary of the invention
Main purpose of the present utility model is to provide a kind of wear on tyres alarming device, when wear on tyres is during to catch siding, reports to the police, and reminds the timely changing of tire of car owner.
For solving the problems of the technologies described above, the utility model wear on tyres alarming device, is arranged on tire, comprises micro-switch and warning device, described micro-switch and warning device are connected in circuit, described micro-switch is arranged in described tire groove, when wear on tyres is during to catch siding position, tire in rolling process as for described micro-switch, described micro-switch is closed under the bearing capacity effect of ground, circuit is connected, warning device work, the timely changing of tire of prompting car owner.
Especially, described warning device is located at the sidewall of described tire.
Especially, described warning device comprises indicator lamp.
Especially, described warning device comprises indicator lamp and buzzer phone.
Compared with prior art, the beneficial effect of the utility model wear on tyres alarming device is, simple in structure, easy to use, described micro-switch is arranged in described tire groove, when wear on tyres is during to predeterminated position, micro-switch is closed under the bearing capacity effect of ground, and trigger alarm device is reported to the police, the timely changing of tire of prompting car owner, and warning device adopts the combination of vision and the sense of hearing, is convenient to car owner and learns in time information warning.

Fig. 3 is the driving circuit connection diagram of the utility model wear on tyres alarming device.
[detailed description of the invention]
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Refer to Fig. 1, shown in Fig. 2, the utility model wear on tyres alarming device, comprise a micro-switch 1 and the indicator lamp 2 as warning device, buzzer phone 3, described micro-switch 1, indicator lamp 2 and buzzer phone 3 are electrically connected in circuit, described warning device can be arranged at the sidewall of described tire 4, described micro-switch 1 is arranged in the sipes per tire of described tire 4, whether wear up to catch siding position for detection of tire 4, in the time that tire 4 wears up to catch siding position, tire 4 in rolling process as for described micro-switch 1, described micro-switch 1 is closed under the bearing capacity effect of ground, circuit is connected, indicator lamp 2 is luminous, buzzer phone 3 is worked, illustrate that tire 4 wears up to catch siding, the timely changing of tire 4 of prompting car owner.
As shown in Figure 3, for the driving circuit connection diagram of the utility model wear on tyres alarming device, described micro-switch 1 one end 12 connects positive source, one end of the other end 11 difference contact resistance R1 and the emitter of aerotron Q2, the base stage of other end connecting triode Q1 of described resistance R 1 and one end of resistance R 2, the base stage of the collecting electrode connecting triode Q2 of described aerotron Q1, its emitter connects the negative pole of power supply, the other end of described resistance R 2 connects one end of filter capacitor C1, the other end of described filter capacitor C1 is the collecting electrode of connecting triode Q2 respectively, the anode of one end of resistance R 3 and buzzer phone 3, the other end of described resistance R 3 connects the anode of indicator lamp 2, the negative electrode of the negative electrode of described indicator lamp 2 and buzzer phone 3 is all connected to power cathode.
In the time that tire 4 wears up to catch siding position, tire 4 in rolling process as for described micro-switch 1, described micro-switch 1 is closed under the bearing capacity effect of ground, and circuit is connected, now, the base stage of aerotron Q1 is high level, the base stage of Q2 is low level, very high level of the current collection of Q2, therefore, buzzer phone 3 is worked, and indicator lamp 2 is luminous; In the time that tire 4 does not wear up to micro-switch 1 place, micro-switch 1 is opened, and buzzer phone 3 is not worked, and indicator lamp 2 does not work yet.
Therefore, whether the utility model works to judge by the bright dark and buzzer phone 3 of indicator lamp 2 whether tire 4 may wear to perch place, illustrates that when indicator lamp 2 is luminous and buzzer phone 3 is worked tire 4 need to change.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
