Furthermore, terms “first” and “second” are used only for descriptive purposes, and are not to be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with the terms “first” and “second” may explicitly or implicitly include one or more such feature. Furthermore, the terms “first”, “second”, etc. are used to distinguish between similar objects and need not be used to describe a particular order or sequence. It should be understood that the terms so used are interchangeable, where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.
For adjustment of an existing vehicle door lock catch, one person on a left side and another person on a right side of vehicles on a production line are required to make fine adjustments to a door of each vehicle coming off the production line. Due to a limited range of adjustments, and because of requirements of the production takt, it is difficult to ensure that mass-produced vehicles on the entire production line are adjusted to a desired quality of sound when the door is closed.
The self-adjusting vehicle door lock catch assembly according to the present disclosure, is designed with the floating adjustment piece and the limit block, which can automatically calibrate the relative position between the lock catch body and the vehicle door according to an actual position of the vehicle door after the vehicle door is closed, such that the vehicle door and the lock catch body are self-adaptively adjusted to a reasonable state in an up and down direction (Z direction) and a left and right direction (Y direction). The lock catch assembly has strong self-adaptive ability, and relatively wide adjustment range, without excessive auxiliary adjustment structures and equipment, which can not only greatly improve the quality of vehicle door closing, but also save labor costs and time costs, ensure product consistency, and improve production efficiency.
