The inertia lock block comprises a body, a first lug, a second lug and a third lug, the tail end of the first lug is close to the handle hook base, the tail end of the third lug is away from the handle hook base, the second lug is located between the inner side of the first lug and the inner side of the second lug, the tail end of the second lug is close to the hook body and can stretch into the locking groove, the body is mounted on the base through a pin shaft in a rotating mode, the pin shaft is sleeved with a torsional spring, and the two ends of the torsional spring support the outside of the first lug and the inner side of the base respectively. The inertia lock mechanism of the vehicle door handle has the advantages that by the adoption of the structure, it can be guaranteed that a vehicle door cannot be opened when the vehicle is subjected to lateral impact, the safety performance of the vehicle is improved, and the structure is simple, mounting is convenient, and the adaptability is high.
Description
Technical field
The present invention relates to a kind of Inertial lock mechanism of door handle for vehicle.
Background technology
Door handle for vehicle is used for car door and car body to pin fixing, door handle for vehicle comprises the base be fixed on car door, be located at the outside of this base and be positioned at door handle body outside car door, be located at balance weight inside this base, one end of this door handle body be provided be located on described base pew seat, the end of this pew seat is convexly equipped with the coupler body of the inner side being positioned at described base, and described balance weight is fixed on described base by balance return button spring.Under normal circumstances, under the effect that cooperatively interact of balance weight with balance return button spring, door handle body has the movement tendency of laminating car door, so just serve the fixing effect of door handle body and car door thus car door can not be opened, when car door is subject to lateral impact, balance return button spring and balance weight then cannot ensure that door handle is shown consideration for and close car door, and car door can unexpected be opened, and leads to a disaster.
Summary of the invention
Above-mentioned deficiency is there is in order to overcome in prior art, the invention provides the Inertial lock mechanism of simple, easy for installation, the adaptable door handle for vehicle of a kind of structure, the unlatching problem that this mechanism can effectively prevent car door from occurring in lateral impact process, substantially increase the security performance of complete automobile collision, effectively can ensure that occupant's takes safety.
The technical scheme that the present invention solves its technical problem is: a kind of Inertial lock mechanism of door handle for vehicle, comprise base, be located at the door handle body in the outside of this base, one end of this door handle body be provided be located on described base pew seat, the end of this pew seat is convexly equipped with the coupler body of the inner side being positioned at described base, the described inertia lock dog being provided with outside the side of pew seat between described coupler body and described base, the end of described coupler body is provided with the inclined-plane of meeting to described inertia lock dog, and this inclined-plane is arranged with lock slots;
Described inertia lock dog comprises main body, and on the outer wall being vertical at this main body and successively spaced first projection, second projection and the 3rd projection, the end of described first projection near described pew seat, the end of described 3rd projection away from described pew seat, the inner side of described second projection between described first projection and the 3rd projection, and the end of described second projection also can stretch in described lock slots near described coupler body, described main body is arranged on described base by bearing pin rotationally, torsion spring is set with outside described bearing pin, the two ends of this torsion spring are supported on the outside of described first projection and the inner side of described base respectively.
Further, the end of described second projection is tip-angled shape, and the end being convenient to the second projection enters in the lock slots of coupler body smoothly.
Further, the inner side of described base is provided with the hinged groove matched with described inertia lock dog, the equivalent locations of the both sides sidewall of this hinged groove offers hinge hole, the two ends of described bearing pin are arranged in corresponding described hinge hole respectively, described in one of them, the inwall of hinge hole is provided with internal spline, the outer wall of one end of described bearing pin is provided with the external splines matched with described internal spline, the outside described bearing pin being positioned at described external splines is provided with limited cap, the inner side of this limited cap is against on the outer wall of described base, described bearing pin is located in the interior also relatively described body rotation of described main body.When mounted, one end that bearing pin does not have limited cap is passed from the hinge hole with internal spline, then through main body, finally be fixed on and do not have in the hinge hole of internal spline, and the external splines on bearing pin matches with the internal spline in hinge hole, thus prevent bearing pin respect thereto from rotating, avoid seat wear, the limited cap on bearing pin can prevent bearing pin respect thereto from sliding.
Further, sheath is arranged with outside described 3rd projection, 3rd projection contacts with base when inertia lock dog turns round thus limits the rotary displacement of inertia lock dog, because inertia lock dog is pivotal under the effect of torsion spring, thus make the 3rd projection to strike base, and the sheath on the 3rd projection avoids the 3rd projection directly to strike base, play cushioning effect.
The present invention is when normally using, namely time by door handle body unlocking vehicle car door, when pulling door handle body outside Vehicular door, drive coupler body near base pew seat, the inclined-plane of coupler body can contact with the medial surface of the first projection of inertia lock dog and drive the first projection near base, this cognition of inertia lock dog is rotated around bearing pin simultaneously, torsion spring outside bearing pin can produce elastic deformation, when unclamping door handle body, coupler body return, inertia lock dog is return under the effect of torsion spring, first projection also return thereupon, can effectively prevent inertial lock block length time motionless torsion spring to get rusty clamping stagnation like this, when inertia lock dog is returned to, 3rd projection can contact with base, play position-limiting action.When Vehicular door is subject to lateral impact, inertia lock dog is prior to door handle body action, namely the body of inertia lock dog rotates around bearing pin, first projection is near base, second projection enters in lock slots along the inclined-plane of coupler body, thus coupler body is pinned, and prevents coupler body near base, and then the locking of door handle body, prevent Vehicular door from opening when lateral impact.
Beneficial effect of the present invention is: adopt said structure, when not only can ensure that automobile side angle clashes into, Vehicular door is not opened, and improve the security performance of automobile, and structure is simple, easy for installation, strong adaptability.
