Abstract

Provided is a force application device for the test of the door-closing speed of a vehicle. The force application device comprises a rack with universal wheels. The device is characterized in that a slide rail is arranged above the rack, a force application rod capable of sliding along the slide rail is arranged in the slide rail, a fixed pulley is fixedly arranged at the upper front part of the slide rail, a steel wire rope latch fixedly connected with the force application rod is arranged at the lower rear part of the slide rail, one end of a steel wire rope arranged on the pulley in a sleeved manner is fixed on the steel wire rope latch, the other end of the steel wire rope is provided with a hook capable of lifting a gravity weight, a force application rod block is arranged at the upper rear part of the force application rod, the upper rear part of the slide rail, corresponding to the force application rod block, is provided with a pin, the pin is movably connected with a handle with a stop pin, and the upper front part of the slide rail is provided with a slide rail block for limiting the force application rod. During practical detection of the door-closing speed, a speedometer is not needed, only the force application device is needed, the vehicle is qualified if the door is closed, and the vehicle is unqualified if the door cannot be closed; and the force application device can be used for the detection of the door-closing speed of left-right doors.

Description

technical field [0001] The invention belongs to the related technical field of motor vehicle performance testing, in particular to a test motor vehicle door closing speed force applying device. Background technique [0002] In automobile quality control, the minimum closing speed of the door is an important indicator to determine whether the state of the door meets the design requirements. In recent years, major domestic OEMs have used door closing speed meters to quantitatively measure and analyze the door closing during the prototype vehicle trial production stage, in order to achieve the best door closing force when the vehicle is finalized. However, when using the door closing speed meter, the following problems are often encountered. The manufacturers who sell the instrument often only sell the instrument, but do not provide supporting force application products. According to the survey, when the vehicle manufacturers use this instrument, professional testers will open...
