Abstract
The utility model relates to an alarming device for a trailer drawn by automobile when a fault occurs, which is suitable for alarming for the faults of the dropping of the tire of the trailer drawn, gas leakage of the tire, and the release from the hook. The utility model comprises an inducting rod (8), a swing arm (5), an inducting arm (3), and an alarm circuit. The utility model is characterized in that the inducting arm is provided with a magnet (13); the place close to the magnet is provided with a reed pipe (10); the swing arm is arranged between the inducting rod and the inducting arm; the binding posts of two reeds of the reed pipe is connected with the alarm circuit. The utility model has the advantages of high sensitivity, good water, sand, and dust resistant performances. The utility model can be used on road surfaces with much water, sand, etc. without the influence of the erosion of contamination.
Description
The utility model relates to a kind of self-propelled vehicle trailer fault alarm, is applicable to that the self-propelled vehicle trailer car tyre drops, the warning of fault such as tire flat and unhooking of two-wheeler.
More existing automobile tyre accident warning devices generally are made of mechanics and corresponding warning circuit, and mechanics has a mechanical switching device that the contact is arranged, the work of this switching device control warning circuit.This warning device exposes or half exposed state because the contact of its mechanical switch is in, and therefore very easily be subjected to the erosion of water, silt, dust etc. and influence, and cisco unity malfunction, fault rate is higher.
The purpose of this utility model provides a kind of new self-propelled vehicle trailer fault alarm, and this annunciator has water-fast preferably, anti-silt and anti-dust performance.
The purpose of utility model realizes by following mode.
Self-propelled vehicle trailer fault alarm, comprise ground connection induction rod, rocking arm, internal induction arm and warning circuit, the internal induction arm is provided with magnet, and the position is provided with reed capsule near magnet, between induction rod and the internal induction arm rocking arm is set, the binding post of two reeds of reed capsule is connected with warning circuit.
The mechanics of annunciator is fixed on the axle of close tire by fixed mount, and the signal generator of warning circuit etc. is located in the operator's compartment.When trailer is in normal condition, the ground connection induction rod generally has 2-3 centimetre distance apart from ground, at this moment, magnet on the internal induction arm is near an end (or middle part) of reed capsule, two reeds in the reed capsule make reed capsule conducting (or disconnection) owing to there is a natural attraction between the sexes (or the same sex is repelled each other), warning circuit is not reported to the police; When tire flat drops air pressure step-down or tire, the ground connection induction rod is not held ground connection, and move backward, driving the internal induction arm by rocking arm moves, make the magnet on the internal induction arm move to middle part (or an end) by an end (or middle part) of reed capsule, make reed capsule disconnected by leading to (or by breaking to logical), at this moment, warning circuit is reported to the police.When unhooking of two-wheeler, equal reed capsule and disconnect, this moment, warning circuit also can be reported to the police.
The self-propelled vehicle trailer fault alarm that the utility model provides, owing to adopt reed capsule as on-off element, so this warning device is highly sensitive; Because switching device is a magnetic-type, the external force of control reed capsule is magnetic force rather than the mechanical force that contact machinery is arranged, reed capsule is an osed top element, therefore, this annunciator has well water-fast, anti-silt and anti-dust performance, can be many at water, long-term work and the not erosion of contaminated thing and influence on the road surface such as silt is many and dust is big, dependable performance, fault rate is low.This annunciator is simple in structure, the life-span long, safety durable, has higher applied value.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is the structural representation of the mechanics of the automotive vehicles trailer fault alarm that provides according to the utility model, and accompanying drawing 2 is left views of accompanying drawing 1, and accompanying drawing 3 is schematic diagrams of alarm equipment alarm circuit.As shown in drawings, annunciator comprises base plate (1), lid (2), internal induction arm (3), retracing spring (4), rocking arm (5), lid screw (6), the stop screw (9) of the bolt (7) of connection rocking arm and ground connection induction rod, ground connection induction rod (8), internal induction arm, reed capsule (10), back clip (11), preceding clip (12) and magnet (13).
As shown in drawings, the trailer fault alarm, comprise ground connection induction rod (8); rocking arm (5), internal induction arm (3) and warning circuit, internal induction arm are provided with magnet (13); near position magnet; be provided with reed capsule (10), between induction rod and the internal induction arm rocking arm are set, and the binding post of two reeds of reed capsule is connected with warning circuit.
Shown in attached Fig. 1 and 2, internal induction arm (8) or rocking arm (5) are provided with retracing spring (4), and the both sides of internal induction arm are provided with stop screw (9).Rocking arm is the crank shape, and the internal induction arm is enclosed within one of rocking arm last and fixed with key, and another of induction rod (8) and rocking arm is connected with lock beans bolt (7).Rocking arm is arranged on the base plate (1), and reed capsule (10), internal induction arm (3), magnet (13) etc. are arranged in the chamber of base plate and lid formation, and magnet is located at the arm end of sensing arm.
In order to prevent that ground connection induction rod (8) from damaging annunciator in the course of the work, induction rod should be a spring, or induction rod wherein one section be spring so that induction rod is can appropriateness crooked.
Front and back clips (12) and (11) are used for mechanics is fixed on the axle of close tire, after The main mechanical part is positioned at axle, can effectively avoid the collision of main body and obstacle, make its safety durable.
As shown in Figure 3, warning circuit adopts the break alarm design.Warning circuit comprises aerotron DG, relay J and signal generator Y, the base stage of aerotron is connected with an end of reed capsule, the emitter of aerotron is connected with the other end of reed capsule, and relay is connected the collecting electrode of aerotron, and signal generator Y is connected with the open contact of relay.Bulb S of reed capsule series connection, as the protecting component of reed capsule, transistor base meets a diode D, as the protecting component of aerotron.Signal generator can adopt buzzer phone.When the reed capsule conducting, aerotron ends, and relay discharges, and signal generator is not reported to the police, when reed capsule disconnects, and the aerotron conducting, the relay adhesive, signal generator is reported to the police.When the line of electrical appliance part in mechanics and the operator's compartment is disconnected, equal reed capsule and disconnect, signal generator is reported to the police.Adopt this break alarm circuit, make the annunciator multi-use, not only can find tire fault, when unhooking of two-wheeler, annunciator also can be reported to the police.In addition, when because of other reason line being disconnected, the driver can in time find and repair, and has more guaranteed the reliability of warning device, and making can reliable operation under the trailer line breaks frequent situation.
All corresponding mechanicals device that a cover annunciator is set of four of trailer tires generally speaking, its reed capsule adopts series connected mode in warning circuit.
