First, the principle of the Hall sensor used in the present invention will be briefly described.

The principle used in hall sensors is based on the hall effect phenomenon. This phenomenon was discovered in the late 1800s. When a magnetic field is applied to a semiconductor and a current flows perpendicularly to the magnetic field, a potential is generated vertically. The voltage may vary depending on the magnetic field, current, semiconductor thickness, and semiconductor type. A device using such a Hall effect is a Hall sensor. The hall sensor is a hall sensor that operates only on and off by the presence or absence of a magnetic field. In addition, if a bias is applied to one side of a cross-shaped sensor like a magnetic field meter, the other side is bias voltage and magnetic field. There are kinds of outputs that are proportional to the strength of, which can be regarded as the difference between one-way and two-way.

1 and 2 and 4A, 4B, and 4C, a preferred embodiment of the present invention will be described. As shown in FIGS. 1 and 3, the combination switch of the present invention is composed of a head part 100, a shaft 200, a rotator part 300, and a housing part 400.

First, the structure of the head unit 100 will be described. A knob 130 that can be rotated in multiple stages for wiper speed adjustment, operates independently of the knob 130, and the knob 130 and The horn button 120 neighboring and elastically mounted at the end thereof, the washer button 110 adjacent to the horn button 120 and the knob 130 and elastically mounted at the end thereof, and the washer button ( 110, a head portion including first to third magnets 112, 122, and 132 and first to third Hall sensors 114, 124, and 134 provided at one end of the horn button 120 and the knob 130, respectively. 100) is configured.

The shaft 200 is connected to one side of the head part 100 to support the head part 100.

A rotator 300 is formed to accommodate the shaft 200 and to guide the front and rear operation of the shaft 200 and the head unit 100 and have a fourth magnet 302 on one side thereof.

The housing part 400 accommodates the rotate part 300, and a plurality of fourths operated by the magnetic field of the fourth magnet 302 according to the front and rear vertical motion of the head part 100 and the shaft 200. Hall sensor 402 is included.

In FIG. 2, the head portion 100 is shown in detail.

The washer button 110 is provided to penetrate the inside of the knob 130 to adjust the wiper speed in multiple stages. The horn button 120 is assembled to penetrate the washer button 110. First and second springs 116 and 126 are coupled to the end of the button 110 and the horn button 120, respectively, and return to their original positions after the pressing operation.

That is, the mixing operation, the washer operation, the wiper speed control has a structure integrated in the head portion (100).

In the combination switch of the present invention, the horn operation, the washer operation, the wiper speed control, and the on / off operation of various lamps are based on a magnet and a hall sensor which is a kind of non-contact switch.

4A and 4B show buttons, magnets, and hall sensors associated with horn and wash operations. The horn button 120 of FIG. 4B is mounted to penetrate the washer button 110 of FIG. 4A.

Looking at the structure, the first and second Hall sensors 114 and 124 are provided in correspondence with the first magnet 112 and the second magnet 122 associated with the horn motion, respectively, and the first and second hall sensors 114 and 124. The second Hall sensors 114 and 124 are mounted on the first PCB substrate 140 formed in the head part 100.

In FIG. 4B, when the horn button 120 is pressed to operate the horn, the second magnet 122 mounted on the lower portion of the horn button approaches the second hall sensor 124, and a magnetic field extends. The horn is designed to operate when entering the distance of.

The magnets used in the present invention are preferably all samarium rare earth magnets. Such rare earth magnets are magnets that are known to have stronger adsorption force and superior heat resistance than ordinary ferrite magnets.

In order to spray the washer fluid in FIG. 4A, the washer button 110 is operated by pressing the first magnet 112 provided in the lower side of the lower side of the washer button 110 to approach the first hall sensor 114. This is going crazy.

The first and second Hall sensors 114 and 124 are formed on the circumference and the center of the first PCB 140, respectively.

Referring to Figure 4c, the principle of operating the lamps by the operation of the knob 130 for adjusting the wiper speed is as follows.

A plurality of third hall sensors 134, a third magnet 132, and a knob 130 are illustrated to correspond to the number of steps of rotating the knob 130.

As the third magnet 132 is mounted to the magnet holder 135 and the knob 130 is rotated, the magnet holder 135 and the third magnet 132 rotate together. The second PCB 142 provided with the third Hall sensor 144 is located corresponding to the third magnet 132.

On the second PCB substrate 142, a plurality of third Hall sensors 134 are disposed radially at a predetermined angle corresponding to the number of rotation stages of the knob 130. If the third Hall sensors 134 are disposed in close proximity to each other, when the third magnet 132 approaches the third Hall sensors 134, two adjacent Hall sensors may malfunction, such as mutual interference. There is a concern. Therefore, the third hall sensor 134 is disposed in the radial form as described above to prevent such a malfunction.

Hereinafter, referring to FIGS. 1 and 5, positions of hall sensors related to lamp operation will be described.

A fourth magnet 302 is provided at an end of the rotate part 300, and a plurality of fourth hall sensors 402 are provided at positions corresponding to the positions of the fourth magnets 302, and the fourth hall sensor The 402 are mounted on a third PCB 406 formed in the housing 400.

That is, when the head part 100 and the shaft 200 are operated by the driver back and forth and up and down, the rotator part 300 to which the shaft 200 is fastened moves together and is mounted on the end of the magnet holder 302. 302 is close to one of the various fourth Hall sensors 402 provided on the third PCB 406 to perform various lamp operations.

For example, as shown in FIG. 5, the hall sensor may be disposed. In other words, the headlamp neutral position (a), the position (b, c) for the left and right indicator lights on both sides, and the three fixed positions (a, b, c) adjacent to each other to fix the upper lamp fixing position (f), the upper lamp The fourth hall sensor 402 is provided in the left and right indicator light position (d, e) in the state of turning on the position, the temporary upward light position (g) for temporarily turning on the upward light. In this case, when it is returned after being positioned at the temporary upward lamp position g, it is based on the elastic force of the return plate 404.

On the other hand, when turned on in the fixed state after turning on the high light, the first roller 204 and the first roller 204 and the first roller 204 is inserted into the first spring roller 202 shown in Figure 1 The first roll 206 connected to the end serves to fix this upward lamp.

If the turn indicator is turned on, the second spring roller 208, the second roller 210, and the roll 212 play the role of keeping the position in the position state.

In the combination switch of the present invention, since the fourth hall sensors 402 are connected in series, the combination switch also has the advantage of reducing the number of ports of the MICOM.

Although the preferred embodiment of the present invention has been described with reference to the drawings, the scope of the present invention is not limited thereto, and the scope of the present invention may be easily added, deleted, or changed by those skilled in the art. It is to be understood that any invention within the scope of the present invention.
