Detailed description of the invention
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for that the present invention is described further.
The two of a kind of hood cover lock of the present embodiment draw opening structure, comprise bracing frame 1, lock pawl 2, rotation clamp 3, 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 that the transition barrier structure 9, the middle part that are hook solid are provided with mesh bulge 10, bottom is provided with the mount surface 11 for hanging bracing wire; The top of rotation clamp 3 is provided with the barrier structure 12 that is used in conjunction with transition barrier structure 9, for the bulge-structure 16 of fixing chuck plate torsion spring 4, after unblanking, play the spacing preiection 15 of position-limiting action, the left side of rotation clamp 3 is provided with the one-level lock mesh bulge 13 and the secondary latch mesh bulge 14 that are used in conjunction with mesh bulge 10.
Installation relation: clamp rivet 8 is riveted on rotation clamp 3 on bracing frame 1 through cover plate 7; Clamp torsion spring 4 is installed on clamp rivet 8, and the non-riveted joint end of clamp rivet 8 plays rotary support effect to clamp torsion spring 4, and bracing frame 1 is fixed in clamp torsion spring 4 one end, and the other end is fixed on rotation clamp 3 bulge-structure places; Lock pawl rivet 6 is riveted on lock pawl 2 on bracing frame 1 through cover plate 7; Lock pawl torsion spring 5 is installed on lock pawl rivet 6, and the non-riveted joint end of lock pawl rivet 6 plays rotary support effect to lock pawl torsion spring 5, and bracing frame 1 is fixed in lock pawl torsion spring 5 one end, and the other end is fixed on lock pawl 2 places.Rotation clamp 3 is provided with bulge-structure 16 can coordinate with bracing frame 1 position-limiting action that plays rotation clamp 3 in the time unblanking; Lock pawl 2 open time rely on the downward bending lifting structure 17 of cover plate 7 to play position-limiting action, after locking lock pawl 2 contact with bracing frame 1 spacing, rotate clamp 3 under the effect of clamp torsion spring 4 around the smooth and easy rotation of clamp rivet 8; Lock pawl 2 can be around the smooth and easy rotation of lock pawl rivet 6 under the effect of lock pawl torsion spring 5.Two opening structures that draw of hood cover lock are opened from lockup state by hair net lock, can, by pulling bracing wire to pull lock pawl 2 to open, pull for the first time bracing wire, and now master lock is opened secondary lock locking; After bracing wire return, pull for the second time bracing wire, secondary lock is opened, and now engine bonnet can freely be opened.
The course of work: when closing automobile engine bonnet, lock pin falls first contact rotation clamp 3 and engages position, rotation clamp 3 is rotated by cover locking force, in rotation clamp 3 rotation processes, contact and force lock pawl 2 to rotate to opening direction around lock pawl axle 6 with lock pawl 2, rotation clamp 3 contacts lock pawl 2 and slides descending, engage with the mesh bulge 10 of lock pawl 2 to rotating clamp 3 secondary latch mesh bulges 14, now lock pawl 2 is subject to lock pawl torsion spring 5 returning place forces to affect revolution in this process, but be subject to the effect of cover locking power, rotation clamp 3 continues to rotate descending until one-level lock mesh bulge 13 is engaged by lock pawl torsion spring 5 returning place forces with the mesh bulge 10 of lock pawl 2, after rotating clamp 2 after master lock locking and can continuing to rotate one section, return completes locking process.
Engine bonnet is opened, pull release pull to open by twice, process: pull for the first time bonnet louver opening handle in driver's cabin, handle bracing wire end makes lock pawl 2 rotate around lock pawl rivet 6, lock pawl 2 is thrown off with the one-level lock meshing relation of rotation clamp 3, rotation clamp 3 promotes lock pin and upsprings under 4 effects of rotation clamp torsion spring, one-level lock is upspring after certain altitude, on rotation clamp 3, set barrier structure 12 matches with transition barrier structure 9 set on lock pawl 2, stop that revotating card 3 plates continue rotation, guarantee that lock pawl 2 is subject to lock pawl torsion spring 5 counter-force returns, rotation clamp 3 secondary latch mesh bulges 14 engage smoothly with the mesh bulge 10 of lock pawl 2, when secondary pulls opening handle, handle bracing wire end pulls lock pawl 2 again, lock pawl 2 rotates around lock pawl rivet 6, lock pawl 2 and the secondary latch meshing relation of rotation clamp 3 are thrown off, rotation clamp 3 continues to promote lock pin under 4 effects of rotation clamp torsion spring upsprings, and the spacing preiection 15 of rotation clamp 3 contacts and stops operating with bracing frame 1, now engine bonnet can freely be opened.
Above-mentioned work engineering of the present invention is for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.Everyly belong to apparent variation or the still row in protection scope of the present invention of variation that technical scheme of the present invention extends out.
