Anti-theft secondary opening cover cap lock and working method thereof

Abstract

The invention relates to an anti-theft secondary opening cover cap lock. A locking mechanism realizes a primary locking function and a secondary locking function through engagement between a clamping board and a clamping claw; a stop plate and the clamping claw are arranged in a coaxial double-layer mode, and co-act with a one-way linkage mechanism, so that a function of opening in a car is realized, an opening operation process of a conventional front cap lock mechanism is simplified, and the risk of a pulling wire from dropping out in a cap closing process is avoided. A safety hook component is simplified, so that the pedestrian safety risk of a sharp bulge in the car is eliminated, convenience is provided for car body arrangement in a main engine plant, the car development cost is reduced, and the reinvestment cost for later-stage development of the front cap lock is saved. An independent ejecting mechanism adopts a direct push type, so that the cap is ejected more smoothly, return force of the clamping board can be reduced, sound of opening and closing the clamping board and the clamping claw is reduced; and the plastic material is adopted, so that the whole car is small in weight.

Description

technical field [0001] The invention relates to the field of auto parts equipment, in particular to an anti-theft type secondary opening cover lock and a working method thereof. Background technique [0002] In order to meet the standard requirements of GB 11568-2011 automobile cover (cover) lock system: the cover lock system should have a second locking device, or a second set of cover lock system should be installed on the cover. The traditional hair cover lock is equipped with two sets of mechanisms, the main lock and the secondary lock hook, or it can be solved by the configuration of two locks. [0003] Due to the difference in the front module of different models, the control part of the safety hook will be different, and different parts of the safety hook will be developed, and the front guard plate of the model will also have different openings, which will affect the integrity of the model; after the main lock of the traditional front cover lock is opened It is nece...

Problems solved by technology

[0003] Due to the difference in the front module of different models, the control part of the safety hook will be different, and different parts of the safety hook will be developed, and the front guard plate of the model will also have different openings, which will affect the integrity of the model; after the main lock of the traditional front cover lock is opened It is necessary to insert the hand into the hood to open the secondary lock and open the hood. In this process, it is troublesome to complete the unlocking action at two positions. Dirty operator's hands cannot provide consumers with more humanized services; traditional front cover locks are mostly all-metal parts, which is not conducive to the lightweight requirements of the vehicle body, and the pallets often use springs with large return force to realize ejection at the same time The function of the hood causes the problem of loud unlocking sound. At the same time, because the functional parts are in a semi-naked state, there are inevitable shortcomings in terms of dustproof, waterproof, and anti-theft; When pressing down, when the clamping plate punches the claws to complete the meshing process, the ball head of the cable does not move, and there is a risk that the cable and the claws will be disengaged, resulting in the situation that the lock cannot be unlocked.
