Glass lifting control device with maximum stroke protection function

Abstract

The invention discloses a glass lifting control device with a maximum stroke protection function, and relates to the technical field of control. The glass lifting control device comprises an output shaft, wherein the inner wall of the output shaft is fixedly connected with elastic sheets which are uniformly distributed; the inner wall of the output shaft is fixedly connected with springs; the outer sides of the springs are fixedly connected with movable blocks; and the outer sides of the movable blocks are rotatably connected with rollers. According to the glass lifting control device with the maximum stroke protection function disclosed by the invention, blocking blocks are matched with gears for use, so that when a motor works, the output shaft drives the gears to rotate, and the gears do not rotate when a car window moves to the maximum stroke, and therefore, the output shaft continuously rotates through action of the motor; moreover, the blocking blocks are extruded into a mounting base while the output shaft drives the mounting base to idle on the middle parts of the gears, so that an overload operation condition of the motor is avoided, and therefore, the effect of protecting the motor is achieved, the motor is prevented from being burnt as a result of over-load operation, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a glass lift control device with a maximum stroke protection function. Background technique [0002] As a means of transportation, cars have become very humanized. For example, car windows have changed from the original manual shaking control up and down to the current electric control up and down, which improves people's driving comfort. Encountered the following problem: [0003] When the window is lifted to the maximum travel position, i.e. the highest or lowest position, the lift control motor cannot stop working in time, causing the motor to continue to work, but because the window has moved to the maximum travel position, it cannot continue to move. At this time The motor is in an overload state, which may cause the temperature of the motor to be too high, causing the motor to burn out and causing unnecessary losses. [0004] Therefore, we propose a glass lifting control ...
