Abstract
A highly reliable, non-maintaining car basin-shaped loudspeaker, the back cover is the conjunctive back cover, lower iron core, contact part, pronunciation part and power connector and back cover are all the gas tightness fixed connection, each other can't dismantle, the precision of the loudspeaker is guaranteed through manufacturing accuracy and assembly precision of the spare part, in the course of using, do not need artificial adjustment and maintenance; because the space formed between the vibrating reed and the rear cover is closed and isolated from the outside, and outside water, harmful gas and oxygen cannot flow into the space, the oxidation corrosion and the aging of the core components of the loudspeaker can be reduced to the maximum extent, the stubborn diseases of electrode burning can be radically treated, if nitrogen or inert gas is injected into the closed space during assembly, the effect is better; the change of the contact mode of the two contacts in the contact part ensures that the electrodes are not easy to accumulate carbon in the working process, further improves the reliability and the service life of the automobile electric horn, and ensures that the automobile electric horn is free of maintenance and has the same service life as an automobile.
Description
Technical field:
The present invention relates to a kind of electric automobile horn, specially refer to have the automobile disc type horn of contact.
Background technology:
Used automobile disc type horn on the vehicles such as present automobile, car, the overwhelming majority is the electric horn of chattering type, the electric horn of this structure is made up of lower core, bonnet, coil, coil pressing plate, contact element, pronunciation part and riveting circle etc., and pronunciation part is made up of armature, vibrating reed, pronunciation sheet.Lower core is by being threaded on the bonnet, mounting coil is on lower core, place in the bonnet, and limit moving axially of coil by the coil pressing plate, vibrating reed and bonnet link into an integrated entity with the riveted mode by the riveting circle, contact element is installed in the bonnet by screw, and wherein the sectional area of two electrode contacts is identical.The electric automobile horn of this structure, serviceable life is short, and reliability is low, and its main diseases is because of as follows:
1. since lower core by being threaded on the bonnet, electric automobile horn in actual use, loudspeaker are subjected to continuous vibration, lower core is easy to become flexible, lower core is moved axially, thereby has changed default magnetic circuit gap between armature core in the pronunciation part and the lower core, the lighter causes the loudspeaker pronunciation uneven, the sound film is failure to actuate, and weight person then can be short-circuited, and burns out until loudspeaker.
2. since between lower core and the bonnet by being threaded, therefore the sealing property in formed space is relatively poor between bonnet and the vibrating reed, extraneous rainwater, corrosive gas, air and dust in air all can be infiltrated in it, can make short circuit, airborne corrosive gas can make each the components and parts corrosion in the loudspeaker and wear out, airborne oxygen helps to produce electric spark between two electrodes in the contact element, the accelerating electrode scaling loss, this is the one of the main reasons that automobile is used contact electric horn weak point in serviceable life, poor reliability.
3. because contact element is installed in the bonnet by screw, same because of vibration cause in actual use, trip bolt is easily loosening, changes predetermined pressure between two electrodes easily, causes loudspeaker malfunctioning.
4. since mounting coil in bonnet, it axially fixes by the coil pressing plate, can coil be fixed, both be subjected to the influence of coil pressing plate self rigidity, be subjected to the influence of coil pressing plate connected mode again, exist multiple factor can make the loosening or distortion of pressing plate in actual use, thereby coil can produce axial float, thereby have influence on the reliability and the voice quality of electric automobile horn.
5. in contact element, because the cross section of two electrode contacts is identical, the electric spark that two electrodes are produced in actual use is easy to carbon distribution on electrode, thereby causes loudspeaker malfunctioning, influences the serviceable life and the reliability of electric automobile horn.
Summary of the invention:
Goal of the invention of the present invention is: a kind of highly reliable, non-maintaining automobile disc type horn is provided, and it can overcome the many deficiencies that have contact automobile disc type horn to have.
Technical scheme of the present invention is: highly reliable, non-maintaining automobile disc type horn of the present invention, comprise bonnet, contact element, coil, coil rack, lower core, pronunciation part, power connector, pronunciation part comprises pronunciation sheet, vibrating reed and armature, coil winding is on coil rack, coil rack is sleeved on the lower core, and place the lower core mounting hole of bonnet, on the E of the lower surface of bonnet, power connector is housed, contact element is housed in bonnet, it is characterized in that: lower core is hermetic fixedlyed connected with bonnet and is integral; Coil rack is fixedlyed connected with lower core; Power connector hermetic is contained on the lower surface E of bonnet, and contact element hermetic is fixedly mounted on the inboard of bonnet lower surface E; Vibrating reed is hermetic fixedlyed connected with bonnet, is provided with the gap, magnetic field between armature and lower core, and vibrating reed is airtight with the formed space of cover cavity, back, is hedged off from the outer world.
As improvement of the present invention, be to fixedly connected between described bonnet and the lower core by welding or interference riveted joint mode, reach the impermeability requirement between the two; Between coil rack and the lower core by riveting together in lower core upper surface shock-produced deformation mode; In contact element, the sectional area of two contact electrode is small one and large one; Both ways of contact are facet and big plane contact or sphere and big plane contact, and the cross section of lower contact electrode is little.
As to further improvement of the present invention, in vibrating reed and the formed space of cover cavity, back, be filled with nitrogen or inert gas.
Because being impermeability between lower core, contact element, pronunciation part and the power connector of electric automobile horn of the present invention and the bonnet fixedlys connected, this connection is non-removable, more can not become flexible to each other, relative positional accuracy between each parts all guarantees by the manufacturing accuracy and the assembly precision of parts, in actual use, need not artificial the adjustment and maintenance.Because formed space is airtight between vibrating reed and the bonnet, be isolated from the outside, armature in the pronunciation part, contact element, coil, key components and partss such as lower core all are in this space, moisture content in the one side external world, harmful gas and oxygen can not flow in this space, thereby can alleviate the oxidation corrosion of these components and parts to greatest extent, aging reaching worn and torn, on the other hand because the oxygen that has in this confined space is limited, loudspeaker in use in the contact element two electrodes when moment contacts, can produce electric spark, nature will consume oxygen, loudspeaker are through after the various detections before dispatching from the factory and testing, the last oxygen in this space is not enough so that produce electric spark between two electrodes, thereby can alleviate electrode erosion, during assembling in this confined space nitrogen injection or inert gas, then can eliminate electrode erosion.Because the present invention improves contact element, change two interelectrode contact collocation modes, adopt small bore to contact or sphere and big plane contact mode with heavy in section, make electrode be difficult for carbon deposit in the course of the work, thereby further improve the reliability and the serviceable life of electric automobile horn, make electric automobile horn reach non-maintaining effect, realize electric automobile horn and same life-span of automobile.
