A Swing Drive Mechanism Used in Central Locking of Automobiles

Abstract

A swing-type drive mechanism for central locking of automobiles, comprising a housing, a drive unit, a transmission unit and a swing unit are arranged in the housing, the drive unit has a motor, the transmission unit has a screw shaft connected to the motor and A transmission seat screwed to the screw shaft, the swing unit has a sector gear engaged with the transmission seat and a swing arm connected to the sector gear, so that when the motor starts, the screw shaft will be driven to rotate, so that the screw shaft drives the transmission seat to move, During the moving process of the transmission seat, the sector gear is driven to deflect, so that the swing arm is driven by the sector gear to swing between a locked position and an unlocked position.

Description

technical field [0001] The invention relates to the central control lock of the automobile, in particular to a swing driving mechanism for the central control lock of the automobile. Background technique [0002] At present, the control of car door locks is mainly to control the opening or closing of other car doors at the same time by means of a central lock, so as to improve the safety and convenience of drivers and passengers. As far as the existing central lock is concerned, it can be roughly divided into push-pull type and swing type. The biggest difference between the two is that the push-pull type central lock uses the push-pull action of a pull rod to drive the door mechanical lock to lock and lock. Unlocking, while the swing-type central lock uses the swing action of a single swing arm to drive the door mechanical lock to lock and unlock. Compared with the push-pull central lock, the swing-type central lock has a smaller size and a lower failure rate. And many adva...

Problems solved by technology

However, as far as the structure of this patent is concerned, the motor must pass through the transmission of the bias device to smoothly drive the threaded shaft to rotate after starting. In addition to increasing the complexity of the structure, it may also affect the mutual relationship due to installation errors. The transmission effect, in addition, between the nut and the swing arm is to use the cooperation between the circular protrusion and the U-shaped groove to achieve the transmission effect, but this structural configuration is easily affected by manufacturing or assembly errors. The movement of the swing arm is not accurate

In other words, this prior patent has the problems of complicated structure, difficult installation and high failure rate
