Description

  The present invention relates to a front body structure of a vehicle, and more particularly to a front body structure of a vehicle in which a bonnet lock for holding a bonnet is fixed by a support member provided on a shroud panel or the like.

  Conventionally, it is known to fix a hood lock for holding a hood with a support member provided on a shroud panel or the like constituting a front wall of a vehicle body.

  Among these, in order to improve the anti-theft property of the vehicle, a technique for fixing a hood lock in the housing portion using a hood lock housing portion (bonnet lock housing portion) having only an upper surface opened as a supporting member is known (for example, Patent Document 1).

  That is, as described in Patent Document 1, a shroud door member provided at the front portion of the vehicle is integrally provided with a hood lock storage portion (bonnet lock storage portion) having an open top surface so that a clearance from the front of the bonnet can be obtained. Even if an attempt is made to release the hood lock, the hood lock is blocked by the hood lock storage portion, so that the anti-theft performance can be improved.

JP 2002-225748 A.

  By the way, when the bonnet is opened and closed, a large load is input to the bonnet lock to support the bonnet load. Therefore, a large load is also input to the support member that fixes the bonnet lock. For this reason, the support member is required to have a support rigidity (durability reliability) that can withstand repeated bonnet opening and closing operations.

  In this regard, when the above-described bonnet lock storage portion having an open top surface is used as a bonnet lock support member, the bonnet lock storage portion has a box shape, so that it has a certain degree of rigidity but is deformed forward at the open portion of the top surface. There is a possibility that so-called opening deformation occurs and sufficient support rigidity cannot be obtained.

  In order to solve this problem, first, it is conceivable to increase the rigidity of the bonnet lock storage part itself by increasing the thickness of the bonnet lock storage part itself.

  However, since the installation position of the bonnet lock storage portion is usually the front end of the vehicle, there is a new problem that when the thickness of the member is increased, the weight of the front end of the vehicle increases and the vehicle maneuverability deteriorates. Arise.

  Therefore, the present invention provides support rigidity (durability reliability) that can withstand repeated bonnet opening and closing operations without increasing the weight, while making the bonnet lock support member open to improve theft resistance. An object of the present invention is to provide a vehicle front body structure that can be secured.

  A vehicle front body structure according to the present invention includes a shroud door upper member that extends in the vehicle width direction at the front of the vehicle body and is connected to both ends of the vehicle body, and an upper end that is connected to a lower part of the shroud door upper member.

  According to the above configuration, the striker and the bonnet lock are engaged with each other through the opening hole, and in other portions, the bonnet lock support member is completely located below the extension portion of the shroud upper member.

  Therefore, since the extension part of the shroud door upper member functions like a lid member of the bonnet lock storage space, the bonnet lock support member can more firmly fix the bonnet lock.

  In one embodiment of the present invention, a front bumper mounting portion is formed on the extending portion of the shroud upper member.

  According to the said structure, a front bumper can be directly fixed to a shroud upper member using an extension part.

  Therefore, the mounting rigidity of the front bumper can be improved by using the shroud upper member which is a rigid member of the vehicle body.

  In addition, since it is possible to eliminate the retainer for fixing the bumper and the cover plate that is concealed, which has been necessary in the past, the number of parts and the weight can be reduced.

  According to the present invention, in the vehicle front body structure for fixing the hood lock to the storage space between the shroud panel and the hood lock support member, the upper portion of the hood lock support member is connected to the extension portion of the shroud door upper member. In addition, forward deformation of the upper part of the bonnet support member, so-called opening deformation can be reliably suppressed.
