Description
Technical field
The present invention relates to the manufacture process technology of arrangements for automotive doors, more particularly to a kind of door external-open handle anticollision to open dress
Put and vehicle.
Background technology
Automobile door external-open handle is the critical function part of door locking system, and door external-open handle be able to will meet in vehicle
By collision particularly side collision when avoid actively opening side door, prevent occupant to be spilled over outside car.
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 forms, as depicted in figs. 1 and 2.Wherein, handle base 10 is fixed by sheet metal component outside car door 11；Outer handle 12 is operating mechanism, one
In the rotation axial trough of handle base 10, the other end coordinates with handle base trim at end；Balance weight 13 is arranged on handle base 10
Fixing groove in, and rotated around its rotary shaft 14；Balance weight torque spring 15 is coaxially disposed with balance weight rotary shaft 14, one end
Coordinate with handle base 10, the other end coordinates with balance weight 13, can ensure outer handle 12 and balance by the effect of torque spring 15
Block 13 is chronically at closed mode.
Wherein, after car door is by larger impact, handle base moves towards body side together in company with the outer sheet metal component of car door,
Due to the effect of inertia force, outer handle is held in place putting, and then outer handle is separated with handle base, causes 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 now outer handle
Center of gravity is arranged in the downside of balance weight rotary shaft, its inertia force and outer handle on the contrary, and then balance the inertia force of outer handle,
Separated so as to avoid outer handle with handle base, it is therefore prevented that the opening of car door.
At present, due to sheet metal component moulding difference outside the car door of different automobile types, cause it different from the gap length of balance weight,
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, calculate and try
Test, waste substantial amounts of energy and material resources.
