Torsion spring assembly detection mechanism suitable for vehicle door locking safety device

Abstract

The invention relates to a torsion spring assembly detection mechanism suitable for a vehicle door locking safety device. The torsion spring assembly detection mechanism comprises a base, a clamping tool, a torsion test function part and a force measurement assembly. The clamping tool is used for clamping the vehicle door locking safety device arranged in the clamping tool. The torsion test function part comprises a driving arm and a power unit, wherein the driving arm moves in the front-back direction, deflects in the circumferential direction under the driving force of the power unit and isused for driving the swing plate to rotate by a preset angle. The force measurement assembly comprises a mounting plate, a front force transfer rod and a front pressure sensor. The mounting plate is fixed on the base, and a front insertion hole extends downwards from the upper plane of the mounting plate. The front force transfer rod and the front pressure sensor are sequentially inserted into thefront insertion hole and abut against each other. When the swing plate rotates to the preset angle, the swing arm abuts against the front force transfer rod under the combined action of the torsionalmoment of the first torsional spring and the torsional moment of the second torsional spring. The front pressure sensor is used for sensing the jacking force borne by the front force transfer rod.

Description

technical field [0001] The invention relates to the technical field of assembly detection of automobile accessories, in particular to a torsion spring assembly detection mechanism suitable for a door locking safety device. Background technique [0002] Typically, vehicles are provided with outer and inner levers for opening and closing the doors on the outside and inside of the doors. A door latch assembly for locking or unlocking a door by operating an outer lever and an inner lever is provided inside the door panel. The outer lever is unintentionally operated by inertial force during a side impact of the door, thereby opening the door. Thereby, in existing high-grade vehicle type, all be equipped with door locking safety device. When the car is subjected to severe impact force, the door lock safety device can effectively prevent the door from being automatically opened, thereby ensuring the personal safety of passengers. [0003] In the prior art, the door locking safet...

Problems solved by technology

However, as far as the current assembly line is concerned, only the quality and performance of the first torsion spring and the second torsion spring of the incoming material are tested, but the overall torsional performance of the door lock safety device after assembly is lacking.

Subsequently, some manufacturers added manual inspection procedures, but the operation process was time-consuming, laborious, poorly intuitive, and it was difficult to reflect the actual torsional strength by means of specific values, resulting in a high detection misjudgment rate
