Automatic clamping failure detection mechanism for automobile seat horizontal drive mechanism

Abstract

The invention discloses an automatic clamping failure detection mechanism for an automobile seat horizontal drive mechanism. An existing automobile seat horizontal drive mechanism detection technology needs to be improved. The automatic clamping failure detection mechanism for the automobile seat horizontal drive mechanism comprises a mechanism bottom plate, a motor installation support, a first slide block, a linear sliding guide rail, a limiting sensor, a transmission transverse plate, a drive motor, a motor shaft sleeve support, an HDM gear case automatic clamping device, an HDM lead screw automatic clamping device and a big-head lead screw support. The HDM gear box automatic clamping device comprises a clamping installation bottom plate, a clamping motor, a linear sliding rail, an HDM gear box clamp, a connecting plate, a second sliding block, an installation base, a lead screw, a spring support, a buffering spring and a flange. The HDM lead screw automatic clamping device comprises a cylinder, a cylinder rod, a small-head lead screw support pressing plate, a small-head lead screw support and a small-head lead screw support top plate. The requirement for the technology of operation staff is low, failure signals are amplified through a vibration clamp, the detection quality is guaranteed, and an HDM mechanism can not be damaged.

Description

technical field [0001] The invention belongs to the technical field of detection and relates to an automatic clamping fault detection device, in particular to an automatic clamping fault detection mechanism for a horizontal driver of an automobile seat. technical background [0002] Car seat horizontal drive (HDM, horizontal drive mechanism) is a mechanism that converts the rotary motion of the drive motor into the linear motion of the car seat slide rail to realize the front and rear adjustment of the seat position. Due to parts processing, assembly errors, bumps or burrs on the tooth surface, etc., a small number of products produce abnormal noise during the operation of the car seat. Once installed on the slide rail, the HDM is affected by the system and knocks. The impact signal is amplified, and it can be heard clearly even when the seat is adjusted in a noisy environment, and due to manufacturing errors, the size of the HDM has a certain dimensional error that is not c...

Problems solved by technology

Because manufacturers, intermediaries and even end customers adopt subjective detection of noise, there is no consistent engineering standard, so many qualified products are misjudged as bad

The artificial discrimination method not only increases the cost of the product because of the subjective judgment of product quality, but also increases the probability of misjudgment and misreceiving of the product, which cannot adapt to the rapid detection of the horizontal drive of the car seat, and is very unfavorable to the quality of the horizontal drive of the car seat detection
