Problems solved by technology

[0005] We found that the Hall electronic horn and the mechanical contact horn in the adaptive control mode currently in use have the same problem: the mechanical action of the riveted one-piece moving stem and the vibrating diaphragm cannot reach a reasonable resonance state, and the diaphragm Vibration and sound under the action of the applied current, when the diaphragm moves to the lower turning point, the position sensor acts and controls the switch tube to be powered off to release the diaphragm to rebound; it is hoped that the diaphragm will release and rebound to the corresponding position above and then energize to attract the diaphragm , in order to obtain the best resonance state
However, as soon as the diaphragm in actual use leaves the lower turning point, the position sensor immediately moves and controls the switching tube to be energized. In this way, the current must first offset the upward kinetic energy of the diaphragm and then attract the diaphragm downward, thus increasing the internal consumption current. Difficult to raise sound level
If you want to increase the sound level, the lower turn-back point must be lowered, which makes the resonant working state worse and the energy consumption is greater

Embodiment 1

[0024] like figure 1 The high-efficiency self-adaptive automotive electronic horn with instantaneous closing and delayed opening as shown, uses a Hall element and a pair of position detection sensors composed of two permanent magnets that are separately arranged on the moving stem and another position in the housing, and the magnetic lines of force are opposite. ; or the photoelectric coupling sensor is used as a position detection sensor, so that the diaphragm is triggered when it is lowered to the lowest position, and the electronic control circuit with the functions of instantaneous closing and delay opening is directly started, and the switch tube is energized when it starts working; At the point, the Hall element triggers the control switch tube to power off, and the diaphragm releases and rebounds. However, when the diaphragm just leaves the lower turning point, the Hall element triggers in reverse in time to make the delay circuit work, and the diaphragm releases and reb...

Embodiment 2

[0029] attached Figure 5 , 6 Provided is the high-efficiency self-adaptive automotive electronic horn with instantaneous closing and delayed opening composed of photoelectric coupling sensors 13, which includes a riveted integral shell 6, a fixed stem 5 and an electromagnetic coil 4, and a riveted integral movable stem 3 and the vibrating diaphragm 2, the moving core column 3 is equipped with a diaphragm moving position marker 7 [that is attached Image 6 The middle visor 14 is composed of], and the position detection sensor assembly 8 that can be adjusted up and down is installed on the housing 6 [that is, the attached Image 6 The photoelectric coupling sensor 13 is composed].

[0030] like Image 6 As shown, the photoelectric coupling sensor 13 at the initial position is blocked by the shading plate 14 and outputs a high potential.

[0031] like Figure 5 As shown, the photoelectric coupling sensor 13 is directly connected and controls the operation of the RC delay el...

Abstract

The present invention provides a quickly switched off and slowly switched on high-effective adaptive car electronic horn. It is characterized by that said car electronic horn includes the following several portions: Hall element, position detection sensor, on-off diaphragm, electronic control circuit, delay circuit and switch tube. Said invention also provides its working principle and its concrete operation method.

Description

Technical field: [0001] The invention relates to a high-efficiency self-adaptive automotive electronic horn with instantaneous closing and delayed opening, which belongs to the category of horns used in motor vehicles, in particular to a position detection sensor that is directly activated and has the functions of instant closing and precise delay opening. Automotive electronic horn composed of electronic control circuit. Background technique: [0002] At present, car electric horns are divided into two categories according to the control method. One is the input mode outside the frequency, which is controlled by various electronic circuits outputting a certain fixed frequency and duty cycle. The products are all non-contact electronic horns; the other is self-adaptive. The method is that the position sensor controls the amplitude, and the vibration frequency is determined by the speaker itself. Its products mainly include traditional mechanical contact speakers and Hall-typ...
