Elastically-clamped bi-directionally-useable protection device for motor

Abstract

The invention discloses an elastically-clamped bi-directionally-useable protection device for a motor and belongs to the technical field of motors. The device includes a housing; the inner wall of theleft side of the housing is movably connected with a gear; a sliding block meshed with the right side of the gear is movably connected to the inner wall of the right side of the housing; a connectingblock slidably connected with the inner wall of the housing is fixedly connected to the middle of the sliding block; first springs distributed evenly are fixedly connected to the top and the bottom of the connecting block; piston rods are fixedly connected to the outer sides of the first springs; and fixing rods are movably connected to the outer sides of the piston rods. The elastically-clampedbi-directionally-useable protection device for the motor of the invention, a movable electric column is matched with a fixed seat so as to be used; and when glass is lifted to a limit state, the sliding block can also move to the top or the bottom under the transmission action of the gear, and the corresponding movable electric column can be separated from the electric contact of the fixed seat todisconnect the circuit of the motor, so that the motor stops working, the motor is effectively protected, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a protective device for electric motors with elastic clamping and bidirectional use. Background technique [0002] A motor is a machine that uses electricity to operate. By converting electricity into mechanical force, it can drive the machinery to work, so that the machinery can achieve the effect of automatic work, which can greatly improve our production efficiency and quality of life, such as in cars. Window lift motor. [0003] The glass lifting motor is mainly used to control the lifting of the glass, which is convenient for the people in the car to adjust the height of the glass, and it is also convenient for the driver to control all the glass. However, when the glass lifting motor is in use, it often encounters overload work. , at this time, when the glass is lowered to the limit position, although the glass will not move anymore, the motor is still in the energ...

[0003] The glass lifting motor is mainly used to control the lifting of the glass, which is convenient for the people in the car to adjust the height of the glass, and it is also convenient for the driver to control all the glass. However, when the glass lifting motor is in use, it often encounters overload work. , at this time, when the glass is lowered to the limit position, although the glass will not move anymore, the motor is still in the energized state, causing the temperature of the motor to rise, seriously affecting the service life of the motor, and it is very likely to cause damage to the motor and shorten the use of the motor life
