Description
Technical field
The present invention relates to the manufacture processing technologies of arrangements for automotive doors more particularly to a kind of door external-open handle anticollision to open dress
It sets and vehicle.
Background technique
Automobile door external-open handle is the critical function component of door locking system, and door external-open handle will be able to satisfy in vehicle
By collision especially side collision when avoid actively opening side door, prevent occupant to be spilled over outside vehicle.
In the prior art, door external-open handle is mainly by portions such as handle base, outer handle, balance weight, balance weight torque springs
Part composition, as depicted in figs. 1 and 2.Wherein, handle base 10 is fixed by sheet metal component 11 outside car door；Outer handle 12 is operating mechanism, one
End is mounted in the rotation axial trough of handle base 10, and the other end and handle base trim cooperate；Balance weight 13 is mounted on handle base 10
Fixing groove in, and around its rotary shaft 14 rotate；Balance weight torque spring 15 and balance weight rotary shaft 14 are coaxially disposed, one end
Cooperate with handle base 10, the other end and balance weight 13 cooperate, and can guarantee outer handle 12 and balance by the effect of torque spring 15
Block 13 is chronically at closed state.
Wherein, after car door is by biggish impact force, handle base is mobile towards body side together in company with the outer sheet metal component of car door,
Due to the effect of inertia force, outer handle, which is held in place, to be set, and then separates outer handle with handle base, leads to car door opening；And
When being equipped with balance weight on handle base, the center of gravity of balance weight is arranged in the upside of balance weight rotary shaft, and outer handle at this time
Center of gravity is arranged in the downside of balance weight rotary shaft, inertia force and outer handle on the contrary, balance the inertia force of outer handle in turn,
It is separated so as to avoid outer handle with handle base, it is therefore prevented that the opening of car door.
Currently, cause it different from the gap size of balance weight due to sheet metal component moulding difference outside the car door of different automobile types,
After the gap width of itself and balance weight is less than safety value, it is necessary to rearrange position and the size of balance weight, and then make difference
The difficulty that door external-open handle generalization between vehicle becomes, and the balance weight rearranged needs to redesign, calculates and try
It tests, wastes a large amount of energy and material resources.
