Abstract

A vehicle hood hinge includes: a lower hinge configured to be fixed to a vehicle body; an upper hinge configured to be fixed to, and supported by, a hood so as to be movable relative to the lower hinge, the hood being configured to open or close an opening formed in an upper surface of the vehicle body; a link mechanism linking the lower hinge with the upper hinge; and a load receiving member configured to support a load of the hood, wherein the link mechanism is configured to switch between pivoting to cause the hood to be pivoted about an axis through the lower hinge and lifting to lift the hood, and the load receiving member is configured to receive, on a front-rear side thereof, the load of the hood lifted through the lifting, to restrict the hood from lowering.

First claim

What is claimed is:

1. A vehicle hood hinge comprising:
a lower hinge configured to be fixed to a vehicle body;
an upper hinge configured to be fixed to, and supported by, a hood so as to be movable relative to the lower hinge, the hood being configured to open or close an opening formed in an upper surface of the vehicle body;
a link mechanism linking the lower hinge with the upper hinge; and
a load receiver configured to support a load of the hood,
wherein the link mechanism is configured to switch between pivoting to cause the hood to be pivoted about an axis through the lower hinge and lifting to lift the hood, and
the load receiver is configured to receive, on an upper end surface thereof, the load of the hood lifted through the lifting, to restrict the hood from lowering.

2. The vehicle hood hinge according to claim 1 , wherein
the load receiver is a spring to elastically receive a load of the hood.

3. The vehicle hood hinge according to claim 2 , wherein
the link mechanism includes a detent portion to abut the top surface of the load receiver, and
the load receiver is provided so as to have the detent portion slidable thereon during the lifting.

4. The vehicle hood hinge according to claim 1 , wherein
the link mechanism includes:
a lower link coupled with the lower hinge; and
an upper link coupled with the lower link and upper hinge,

wherein the lower link includes a first stopper to restrict a pivoting range of the upper link with respect to the lower link, during the lifting.

5. The vehicle hood hinge according to claim 4 , wherein
the link mechanism includes a detent portion to abut a top surface of the load receiver, and
the lower hinge includes a second stopper to restrict a lifting range of the detent portion, during the lifting.

6. The vehicle hood hinge according to claim 5 , further comprising:
a second spring to bias the detent portion toward the lower hinge.

7. The vehicle hood hinge according to claim 6 , wherein
the link mechanism includes:
a lower link coupled with the lower hinge; and
an upper link coupled with the lower link and upper hinge,

wherein the second spring gives a resistive force to the lower link during the lifting.

8. The vehicle hood hinge according to claim 1 , further comprising:
a lock member pivotally supported by the upper hinge and configured to switch between a locking state of engaging with the link mechanism to have the link mechanism locked and an unlocking state of having been disengaged from the link mechanism to have the link mechanism unlocked; and
a first spring biasing the lock member toward a position for the locking state.

9. The vehicle hood hinge according to claim 1 , further comprising:
a lock member pivotally supported by the upper hinge and configured to switch between a locking state of engaging with the link mechanism to have the link mechanism locked and an unlocking state of having been disengaged from the link mechanism to have the link mechanism unlocked,
wherein
the upper hinge a cup portion pushed by the actuator, and
the lock member has a projection to be inserted into a slot formed in the cup portion so as to be positioned inside the cup portion, and to be pushed by the actuator.
