Specific embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, for the present invention is described further.
A kind of the double of hood cover lock of the present embodiment draw opening structure, including bracing frame 1, lock pawl 2, rotation clamp
3rd, clamp torsion spring 4, lock pawl torsion spring 5, lock pawl rivet 6, cover plate 7, clamp rivet 8.Wherein, the top of lock pawl 2 is provided with and is in
The transition barrier structure 9 of hook solid, middle part are provided with engagement projection 10, bottom is provided with the mount surface 11 for hanging bracing wire；Rotation
The top turning clamp 3 is provided with the barrier structure 12 using cooperatively with transition barrier structure 9, the projection for fixing chuck plate torsion spring 4
Structure 16, play the spacing preiection 15 of position-limiting action after being unlocked, the left side of rotation clamp 3 is provided with and engages raised 10 and use cooperatively
One-level lock engagement raised 13 and secondary latch engagement raised 14.
Installation relation: clamp rivet 8 passes through cover plate 7 to be riveted on rotating clamp 3 on bracing frame 1；Clamp torsion spring 4 is installed
To on clamp rivet 8, rotation supporting role is played at the non-riveting end of clamp rivet 8 to clamp torsion spring 4, and clamp torsion spring 4 one end is fixed
In bracing frame 1, the other end is fixed at rotation clamp 3 bulge-structure；Lock pawl 2 is riveted on by lock pawl rivet 6 through cover plate 7
On bracing frame 1；Lock pawl torsion spring 5 is installed on lock pawl rivet 6, the non-riveting end of lock pawl rivet 6 is to lock pawl torsion spring 5
To rotating supporting role, bracing frame 1 is fixed in lock pawl torsion spring 5 one end, and the other end is fixed at lock pawl 2.On rotation clamp 3
It is provided with the position-limiting action that bulge-structure 16 can play rotation clamp 3 when unlocking with bracing frame 1 cooperation；Lock pawl 2 is being opened
When rely on the downward bending lifting structure 17 of cover plate 7 to play position-limiting action, after locking, lock pawl 2 contacts spacing with bracing frame 1, revolves
Turn clamp 3 in the presence of clamp torsion spring 4 around the smooth rotation of clamp rivet 8；Lock pawl 2 can in the presence of lock pawl torsion spring 5
Around the smooth rotation of lock pawl rivet 6.The double of hood cover lock draw opening structure to be locked from lockup state unlatching by hair net, can pass through
Pull bracing wire to pull lock pawl 2 to open, pull bracing wire for the first time, now secondary lock locking opened by main lock；After bracing wire return, second
Pull bracing wire, secondary lock is opened, and now engine bonnet can freely be opened.
Work process: during closing automobile engine bonnet, lock pin falls first contact rotation clamp 3 site of engagement, revotating card
Plate 3 is rotated by cover locking force, contact with lock pawl 2 in rotation clamp 3 rotation process force lock pawl 2 around lock pawl axle 6 to
Opening direction rotates, and rotation clamp 3 contact lock pawl 2 simultaneously slides descending, to rotation clamp 3 secondary latch engagement raised 14 and stop
The engagement of pawl 2 raised 10 is engaged, and now lock pawl 2 is affected to turn round by lock pawl torsion spring 5 returning place force in the process, but is subject to cover
Locking force acts on, and rotation clamp 3 continues to rotate descending until one-level lock engagement raised 13 is only subject to the projection 10 that engages of lock pawl 2
Pawl torsion spring 5 returning place force engages, and after after main lock locking, rotation clamp 2 can continue to rotate one section, return completes locking process.
Engine bonnet is opened, and is opened by pulling release pull twice, process: starts driving indoor pulling for the first time
Hood lock opening handle, handle bracing wire end makes lock pawl 2 rotate around lock pawl rivet 6, the one-level of lock pawl 2 and rotation clamp 3
Lock meshing relation disengagement, rotation clamp 3 promotes lock pin to upspring under rotation clamp torsion spring 4 effect, and one-level locks certain altitude of upspringing
Afterwards, on rotation clamp 3, set barrier structure 12 is matched with set transition barrier structure 9 on lock pawl 2, stops revotating card
3 plates continue rotation it is ensured that lock pawl 2 is subject to lock pawl torsion spring 5 counter-force return, rotation clamp 3 secondary latch engagement raised 14 and stop
The engagement projection 10 of pawl 2 smoothly engages；When secondary pulling opening handle, handle bracing wire end pulls lock pawl 2, lock pawl 2 again
Rotate around lock pawl rivet 6, so that lock pawl 2 and the secondary latch meshing relation of rotation clamp 3 is disengaged, rotation clamp 3 is in revotating card
Continue to press on lock pin under plate torsion spring 4 effect to upspring, the spacing preiection 15 of rotation clamp 3 is contacted with bracing frame 1 and stops operating；Now
Engine bonnet can freely be opened.
The above-mentioned work process of the present invention is intended to clearly illustrate example of the present invention, and is not to the present invention
The restriction of embodiment.Every belong to the obvious change that technical scheme extended out or change still in this
The row of the protection domain of invention.
