Lock cylinder assembly of vehicle overturning door, vehicle overturning door lock and vehicle

Abstract

The invention relates to a lock cylinder assembly of a vehicle overturning door, a vehicle overturning door lock and a vehicle. The lock cylinder assembly of the vehicle overturning door comprises a base mounted on a vehicle body and a hollow lock cylinder main body which is arranged on the base and is used for being matched with a lock body mounted on the vehicle overturning door, wherein the lock cylinder main body has an initial position; the lock cylinder assembly comprises a driving adjusting mechanism; the driving adjusting mechanism is in transmission connection with the lock cylinder main body so that the lock cylinder main body can be driven to move away from the initial position on the base along the adjusting movement direction or is reset to the initial position, and furthermore, the fastening force between the lock cylinder main body and the lock body can be adjusted by the movement of the lock cylinder main body under the locking state of the lock body and the lock cylinder main body. By the aid of the lock cylinder assembly of the vehicle overturning door provided by the invention, the vehicle overturning door can be effectively prevented from resonance.

Description

Technical field [0001] The invention relates to a lock, in particular to a lock post assembly of a vehicle flip door, a vehicle flip door lock and a vehicle. Background technique [0002] The quality and structure of the clamshell door (such as the back door), which is an important part of the body in the SUV or sports hatchback vehicle, not only affects the safety performance of the vehicle and the performance of the entire vehicle, but also affects the comfort of the vehicle . Take the back door of a vehicle as an example. When the vehicle is driving, the back door vibrates due to uneven road surface, wind resistance, vehicle speed, or engine operation, etc., because the overall mode of the back door is relatively low. If the vibration frequency of the vehicle body caused by the above-mentioned vibration source reaches within the modal frequency range of the back door, it can cause the back door to resonate with the vehicle body, resulting in severe vibration and low-frequency...

AI Technical Summary

Problems solved by technology

However, since the dynamic vibration absorber is additionally provided on the flip door, not only the overall quality and structure of the flip door will be changed, but also the frequency of the dynamic vibration absorber rubber or other elastic mechanisms will change after a long period of use, thereby reducing the vibration absorber. vibration-absorbing effect
