Technical field
The utility model relates to a kind of auto-parts, particularly relates to a kind of electric automobile horn.
Background technology
Electric horn is the warning parts that each automobile must be equipped with, traditional snail sound cylinder electric horn, as shown in Figure 1, comprise trumpet projector 1, trumpet projector cover plate 2, collar 3, diaphragm unit 4 and chassis assembly 5, trumpet projector cover plate 2, collar 3, diaphragm unit 4 rivets into loudspeaker sub-unit in order with chassis assembly 5, trumpet projector 1 comprises spiral case 11 and cover plate centring ring 12, cover plate centring ring 12 is arranged in the outer periphery of spiral case 11 tone channel end face, and be cast into one with spiral case 11, spiral case 11 tone channel end face is arc surface, the trumpet projector cover plate 2 of loudspeaker sub-unit is sleeved in the cover plate centring ring 12 of trumpet projector 1, the lateral surface of trumpet projector cover plate 2 is docked with being sealed by adhesive glue between spiral case 11 tone channel end face, be fixedly connected with by adhesive glue between the periphery of trumpet projector cover plate 2 and the cover plate centring ring 12 of trumpet projector 1.This electric horn bonded structure technical requirement high glue-spread is crucial, very little, bonding unreliable, gluing is excessive for gluing, easily cause glue from overflowing, light then can outward appearance be changed, heavy then tone channel acoustic area of section can be changed, directly affect loudspeaker pronunciation tonequality, and when by loudspeaker sub-unit press-in trumpet projector assembly medial surface, fit quality between the two can not be guaranteed, and causes the boundary condition of diaphragm unit 4 poor, have impact on the raising of the sound pressure level of screw-type klaxon.Because the lateral surface of trumpet projector cover plate 2 is male type, so the medial surface of trumpet projector 1 must make the circular arc type of indent, and trumpet projector 1 is combined by spiral case 11 and cover plate centring ring 12, and complex manufacturing technology, cost is high.
Utility model content:
The purpose of this utility model is to provide one and exempts from the bonding screw-type klaxon of glue, and its assembling is more convenient, reliable, appearance looks elegant, and sound by glue water mitigation, is not met the need of market ideally.
The utility model adopts following technical scheme to realize:
One exempts from the bonding screw-type klaxon of glue, comprise trumpet projector, trumpet projector cover plate, collar, diaphragm unit and chassis assembly, it is characterized in that: collar, diaphragm unit and chassis assembly rivet into loudspeaker sub-unit in order, trumpet projector cover plate comprises retainer plate and fixed panel, one end of retainer plate is fixedly connected with integral with fixed panel, the other end medial surface of retainer plate is provided with collar, the diameter of bore of retainer plate is corresponding with the external diameter of collar, the diameter of bore of collar is less than the external diameter of collar, trumpet projector cover plate is installed on the collar end of loudspeaker sub-unit by the collar on retainer plate, resonator is formed between trumpet projector cover plate and loudspeaker sub-unit, through hole is had at fixed panel center, the medial surface through hole surrounding of fixed panel is provided with inner concave, the lateral surface of fixed panel is provided with interior spacing collar and outer spacing collar, interior spacing collar is arranged on the surrounding of through hole, the diameter of bore of interior spacing collar is equal with the aperture of through hole and coaxial, interior spacing collar to be installed in trumpet projector in center channel hole, outer spacing collar is installed on the periphery of the spiral case of trumpet projector, the contact-making surface of trumpet projector and trumpet projector cover plate is installed surface, the installed surface of trumpet projector is plane, ultrasonic bonding is passed through between the installed surface of trumpet projector and the fixed panel of trumpet projector cover plate.
Further, at the medial surface of the fixed panel of trumpet projector cover plate, retainer plate junction is provided with friction limit.
Owing to making the structure of trumpet projector cover plate into retainer plate and fixed panel links into an integrated entity, retainer plate is provided with collar, trumpet projector cover plate can overall directly be installed on the loudspeaker sub-unit that collar, diaphragm unit and chassis assembly rivet, and consistency is better, installs more convenient.The structure of trumpet projector have also been made change according to the change of trumpet projector cover plate, original cover plate centring ring is removed, installed surface changes plane into by arc surface, make more simple and convenient, installation between trumpet projector and trumpet projector cover plate is reliably more convenient, and whole spiral electric horn is all fixed without the need to glue in manufacturing process.
