Permanent magnet solenoid booster

Abstract

The invention discloses and provides a permanent magnet solenoid booster which is simply structured, is electromagnetically driven to generate power and generates stable power. According to the technical scheme of the invention, the permanent magnet solenoid booster comprises a shell, a push rod and a first mounting seat, wherein the push rod runs through the two sides of the shell; the first mounting seat is fixedly arranged at the middle part in the shell; a plurality of groups of series-connected solenoid rings are fixedly arranged in the first mounting seat; the solenoid rings and the pushrod are coaxially arranged; a contact is arranged on each solenoid ring; an internal magnet ring sleeves the middle part of the push rod; a first contact block matched with the contact is arranged onthe external end surface of the internal magnet ring; a second contact block matched with the contact is arranged outside one side of the internal magnet ring; and the first contact block and the second contact block are correspondingly connected to an anode and a cathode of a power supply circuit through leads. The permanent magnet solenoid booster can be used for the technical field of boosters.

Description

technical field [0001] The invention relates to a permanent magnet solenoid booster. Background technique [0002] Due to the limited human strength, the operation of the vehicle often requires power-assisted devices. For example, the vehicle uses compressed air, high-pressure oil and other boosters to control the related devices of the vehicle to achieve the purpose of lightness of use. The traditional booster is often a vacuum booster or an electric booster. The use of a vacuum booster requires the combined action of a supporting engine, a vacuum pump and a motor to achieve the boosting effect, and there are many components; while the electric booster uses the motor to directly drive the boosting element to generate power. , the motor burden is heavy; the invention patent of Chinese Patent Publication No. 203996170U discloses a brake pedal booster, which mainly includes a pedal, a push rod, a return spring, a housing, a guide bearing, an electromagnetic coil, an iron core,...

The traditional booster is often a vacuum booster or an electric booster. The use of a vacuum booster requires the combined action of a supporting engine, a vacuum pump and a motor to achieve the boosting effect, and there are many components; while the electric booster uses the motor to directly drive the boosting element to generate power. , the motor burden is heavy; the invention patent of Chinese Patent Publication No. 203996170U discloses a brake pedal booster, which mainly includes a pedal, a push rod, a return spring, a housing, a guide bearing, an electromagnetic coil, an iron core, an electric current Controller, pressure sensor, the brake pedal booster uses an electromagnetic coil to generate a magnetic field, and then uses the magnetic field to attract the magnetic force generated by the characteristics of the iron core to convert it into a booster. However, when the booster is in use, the distance between the iron core and the electromagnetic coil is different. The suction is different, and the suction may be too small or too large, so the boosting effect is unstable
