A detailed configuration for switching on / off the vacuum pumps 200, 200a and 200b of the vacuum switch 100 having the above-described overall coupling structure will be described below.

The nozzle unit 110 has a tubular nozzle 111 through which a center thereof is formed to introduce external air to the bottom surface, and communicates the inside of the nozzle unit 110 with the vacuum brake system, and the nozzle 111 protrudes. The driver groove screwed into the nozzle 111 so as to move up and down inside the nozzle 111 by the rotation of the nozzle 111 and the tubular nozzle body 101 whose diameter is expanded in the portion and is opened. The formed screw 112 and one end is supported by the screw 112 and the other end is configured to include a spring member 113 in close contact with the bottom surface of the diaphragm portion (130). The nozzle body 101 is the position where the horizontal outer periphery 131b of the diaphragm 131 is seated after the inner diameter increases at the position where the through hole formed in the nozzle 111 ends, the horizontal outer periphery 131b of the diaphragm 131. ) Has an internal structure in which the inner diameter is further enlarged so that the stepped portion is formed to be seated and supported. The screw 112 is an example of the elastic control of the present invention.

In the nozzle unit 110 having the above-described configuration, the spring member 113 diaphragms by adjusting the position of the screw 112 and the gap between the moving electrode 136 and the fixed electrode 152 in the nozzle 111. The size of the elastic force supporting the portion 130 is adjusted.

The diaphragm 130 includes a diaphragm 131 on which a bottom surface is supported at an upper portion of the spring member 113, and a horizontal outer periphery 131 b of the diaphragm 131. And an upper end of the annular diaphragm guide 133 seated on the upper portion of the horizontal outer periphery 131b of the diaphragm 131 seated on the upper end of the inner step of the nozzle body 101 so as to be in close contact with the stepped portion formed in the inner side of the nozzle unit body 101. A moving electrode 136 is formed at the center and inserted into a through hole formed at the center of the annular diaphragm guide 133, and then the outer surface thereof is supported by the diaphragm guide 133 and the bottom surface is coupled to the upper surface of the diaphragm 131. It comprises a finger 135.

The diaphragm 131 is made of an elastic member having an elastic force to be restored to its original shape when the shape changes. The diaphragm 131 is elastic and the multi-stage cylindrical elastic resistance portion 131a which gradually decreases in diameter to the bottom surface so that the diaphragm 131 becomes convex to the nozzle portion 110 toward the diaphragm 131. A horizontal outer periphery 131b is formed to extend in the horizontal direction along the circumference at the upper end of the resistor portion 131a.

The micro-switch unit 150 has a fixed electrode 152 formed on a bottom surface of the micro switch 150 facing the moving electrode 136, and two switch electrodes connected to the fixed electrode 152 and the moving electrode 136, respectively. 153 is formed to include a switch socket 151, the lower end region including a surface on which the fixed electrode 152 is formed is inserted into the nozzle body body 101 from the top of the nozzle body body 101 is fixed It is composed. In this case, when the fixed electrodes 152 are formed in two and the moving electrode 136 is configured to energize the two fixed electrodes 152, the two switch electrodes 153 are connected to the respective fixed electrodes 152.

By the above-described structure, the vacuum switch 100 of the present invention performs mechanical vacuum switching, not electronic.

The vacuum switch 100 of the present invention having the above-described configuration is mounted at any position of the vacuum flow path by the O-ring 102 so that the region where the microswitch portion 150 is located maintains atmospheric pressure, and the diaphragm portion 130 The lower nozzle body body 101 region turns on / off the vacuum pumps 200, 200a and 200b in accordance with the change of the vacuum pressure inside the brake system while maintaining the negative pressure state by the vacuum.

At this time, by the structural features of the diaphragm 130 as described above, the vacuum switch 100 of the present invention is driven in a double point switching control method to turn on / off the micro switch 150 at different pressures.

At this time, the high pressure value for the deformation of the diaphragm 131 is adjusted by adjusting the position of the screw 112, and the low pressure value is adjusted between the moving electrode 136 and the fixed electrode 152. Adjust by adjusting the interval.

In detail, the elastic resistance part 131a adds a force to the diaphragm 131 so that the diaphragm 131 is convexly deformed into the nozzle part 110. As a result, the diaphragm 131 is convexly shaped toward the microswitch unit 150 in a state where the inside of the nozzle unit 101 has a high air pressure, thereby turning on the microswitch unit 150 to vacuum pumps 200, 200a and 200b. ). On the contrary, when the micro switch unit 150 is turned off, the diaphragm 131 is convex downward when the air pressure inside the nozzle body 101 becomes a negative pressure lower by the force added by the elastic resistance unit 131a. The shape is changed so as to turn off the micro switch 150, thereby stopping the driving of the vacuum pumps 200, 200a, 200b.

As described above, since the on / off of the microswitch unit 150 is performed at different air pressures, the double point switching control method of fundamentally eliminating the occurrence of the chattering is implemented, as well as the vacuum tank 300 (FIG. 1). The interior of the cylinder will always be at a lower pressure.

Therefore, the vacuum switch 100 of the present invention can perform the braking operation a greater number of times compared to the prior art whether the vacuum is restored to an appropriate pressure when the brake operation is performed, thereby significantly improving the safety of the vehicle. .

The configuration and operation characteristics for the double point switching control method of the diaphragm unit 130 will be described in detail with reference to the numerical example of the vacuum pressure.

The air pressure at which the diaphragm 131 is deformed so that the fixed electrode 152 and the moving electrode 136 of the microswitch unit 150 are shorted and the microswitch unit 150 is turned on is set to (600 ± 10) mHg. The air pressure at which the diaphragm 131 is deformed so that the fixed electrode 152 and the moving electrode 136 of the microswitch unit 150 is opened to turn off the microswitch unit 150 is set to (400 ± 10) mHg. As such, it is assumed that the microswitch unit 150 is turned on / off at different air pressures so that the vacuum switch 100 is turned on / off in a double point switching method.

In this case, the internal pressure of the diaphragm 131 in the lower region of the diaphragm 131 by the elastic resistance part 131a, that is, the lower internal region of the nozzle body body 101 on which the spring member 113 is mounted is (600 ± 10). In the case of mHg, the diaphragm 131 is deformed to protrude toward the microswitch unit 150 and the movable electrode 136 is shorted with the fixed electrode 152 so that the microswitch unit 150 is turned on and the vacuum pumps 200 and 200a. , 200b) to perform vacuum.

After the vacuum is performed, the diaphragm 131 is convexly shaped downward when the internal air pressure of the inner lower region of the nozzle body 101 on which the spring member 113 is mounted is (400 ± 10) mHg. By opening the moving electrode 136 from the fixed electrode 152, the micro switch unit 150 is turned off to stop the driving of the vacuum pumps 200, 200a, and 200b.

The deformation of the diaphragm 131 at different air pressures is caused by the elastic resistance portion 131a of the diaphragm 131 adding an elastic force that causes the diaphragm 131 to be convexly deformed into the nozzle 111. And the elastic force acting at the time of the upward convex deformation and downward convex deformation.

The double point switching control method, which is a feature of the present invention, is performed by the shape feature of the diaphragm unit 130.

The present invention can be used with vacuum pumps, such as a dry vacuum pump or a wet vacuum pump.
