Abstract
The utility model discloses an electromobile bitone electric horn controlling device, comprising a first horn, a second horn, a relay and a relay switch, wherein the first horn and the second horn are respectively connected with a contact H of the relay, a contact B of the relay is connected with a positive electrode of a battery, and a contact S of the relay is connected with the relay switch. According to the utility model, the two horns are spiral electric horns and are controlled by the horn relay, low current of an iron-core coil is used to control heavy current of the contacts, so a button contact of a steering wheel is protected, and a button is prevented from burning, thereby prolonging the service lives of the horns and the button.
Description
Technical field
The utility model belongs to the electric automobile applied technical field, particularly a kind of electric automobile double-tone electric horn control device.
Background technology
On the conventional fuel-engined vehicle loudspeaker are housed all, are used for warning pedestrian and other vehicles, to arouse attention, guarantee traffic safety.Loudspeaker divide air horn and electric horn two classes by the difference of pronunciation power; By the profile branch spirality, tubular, basin shape three classes are arranged.By the audio frequency branch two kinds of high pitch and basses are arranged.Along with the development of society, the car owning amount of China is increasing, and environmental pollution, energy shortage problem are also serious day by day.Electric automobile just grows up, and a lot of configurations are still waiting perfect, does not have air pump dress electric horn on the electric automobile, and conventional electric horn noise is too big, electric automobile is sailed in the urban district at present more, and general city is no tooting, therefore needs a kind of new loudspeaker that can be used for electric automobile.
The utility model content
In view of this, the purpose of this utility model provides a kind of electric automobile double-tone electric horn control device, simple in structure, cost is cheap, volume is little, energy-conservation, easy for installation.
To achieve these goals, the utility model is by the following technical solutions:
A kind of electric automobile double-tone electric horn control device wherein, comprises first loudspeaker, second loudspeaker, relay and relay switch; Described first loudspeaker, second loudspeaker are connected with the contact H of relay respectively, and the contact B of relay connects battery positive voltage, and contact S connects relay switch.
As preferably, described first loudspeaker, second loudspeaker are the spirality electric horn.
The beneficial effects of the utility model are:
The utility model has adopted the electric horn of two different tones (high and low sound), and the loudspeaker diaphragm is thick, raise one's voice brief, and bass horn is then opposite, obtains comparatively harmonious euphony.Two loudspeaker are the spirality electric horn, adopt electric horn breaker point unit control, utilize the big electric current of the little Current Control contact of ironcore choke, thereby protection bearing circle push-button contact can not burnt out button, thereby prolonged the serviceable life of loudspeaker and button.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following instructions or the accompanying drawing.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises first loudspeaker 1, second loudspeaker 2, relay 3, relay switch 4 and accumulator 5; First loudspeaker 1, second loudspeaker 2 connect the contact H of relay 3, and the contact B of relay 3 connects accumulator 5 positive poles, and contact S connects relay switch 4.First loudspeaker 1, second loudspeaker 2 are the spirality electric horn, have adopted the electric horn of two different tones (high and low sound), and the loudspeaker diaphragm is thick, raise one's voice brief, and bass horn is then opposite.
The course of work of the present utility model is:
When pressing on the bearing circle horn button, electric horn breaker point unit coil, current potential relay core produce electromagnetic attraction, with relay contact closure, have connected the double-tone electric horn, the loudspeaker pronunciation.When unclamping the bearing circle horn button, relay coil outage, electromagnetic attraction unshakable in one's determination disappears, and open under self elastic force effect the contact, has cut off electric horn circuit, and electric horn stops pronunciation.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. an electric automobile double-tone electric horn control device is characterized in that: comprise first loudspeaker, second loudspeaker, relay and relay switch; Described first loudspeaker, second loudspeaker are connected with the contact H of relay respectively, and the contact B of relay connects battery positive voltage, and contact S connects relay switch.
