Problems solved by technology

Therefore, when an impact load is input to the dash panel, it is conceivable that the upper left cross member and the upper right cross member will break and the upper cross member will be displaced due to the impact load.
[0008] Due to the displacement of the upper beam, there is a potential for the striker to disengage from the hood lock and the hood to open

Embodiment 1

[0127] The vehicle body front structure 10 of the first embodiment will be described.

[0128] Such as figure 1 , figure 2As shown, the vehicle body front structure 10 has: the left and right front side frames 11 provided on the left and right sides of the vehicle Ve, the left front pillar 12 provided on the rear end of the left front side frame 11, the left front pillar 12 provided on the right front side frame 11. The right front pillar 12 at the rear end, the subframe 13 attached to the left front side frame 11 and the right front side frame 11 from below, and the left and right floor frames 14 arranged behind the vehicle body of the subframe 13 .

[0129] Additionally, if image 3 , Figure 4 As shown, the front structure of the vehicle body 10 has: from the left front pillar 12 (refer to figure 1 ) the left upper member 16 extending to the front of the vehicle body, the right upper member 16 extending from the right front pillar 12 to the front of the vehicle body, t...

Embodiment 2

[0410] The vehicle body front structures 240 and 250 of Embodiment 2 and Embodiment 3 are substantially bilaterally symmetrical structures similarly to the vehicle body front structure 10 of Embodiment 1. Hereinafter, the components on the right side will be specifically described and the left side will be omitted. A description of the constituent parts.

[0411] Example 2

[0412] The vehicle body front structure 240 of the second embodiment will be described.

[0413] Such as Figure 35 As shown, the front structure 240 of the vehicle body replaces the right connecting mechanism 27 of the first embodiment with the right connecting mechanism 241 , and the other structures are the same as the front structure 10 of the first embodiment.

[0414] The right coupling mechanism 241 has: an adjustment support plate 242 embedded in the lower right corner portion 101 of the bulkhead portion 76 by insert molding, an adjustment nut 243 fixed to the adjustment support plate 242 , and a...

Embodiment 3

[0428] The vehicle body front structure 250 of the third embodiment will be described.

[0429] Such as Figure 37 As shown, the front structure 250 of the vehicle body replaces the right connecting mechanism 27 of the first embodiment with the right connecting mechanism 251, and other structures are the same as the front structure 10 of the first embodiment.

[0430] The right connecting mechanism 251 replaces the adjusting collar 134 of the first embodiment with an adjusting collar 252, and other structures are the same as the right connecting mechanism 27 of the first embodiment.

[0431] The upper surface 252 a of the adjustment collar 252 is fixed (ie bonded) to the lower surface 101 a of the lower right corner portion 101 by an adhesive 253 .

[0432] According to the right connecting mechanism 251 of the third embodiment, similarly to the right connecting mechanism 27 of the first embodiment, it can be connected with the lower surface 101a of the lower right corner 101...

Abstract

This vehicle body front portion structure (10) is provided with a front bulkhead (21). The front bulkhead (21) is provided with: a resin right side stay (87) that is connected to a right front side frame (11); a metal right upper side beam (78) that extends from the right side stay (87) to a right upper member (16); a metal upper beam (79) that is detachably connected to the right upper side beam (78); and a hood locking device (35) that is provided on the upper beam (79). A right end (79b) of the upper beam (79) is connected so as to sandwich the right side stay (87) in a vehicle body fore-aft direction.

Description

technical field [0001] The present invention relates to a vehicle body front structure in which a front side frame, an upper member, and a front bulkhead are provided around an engine compartment as frame materials of the vehicle body. Background technique [0002] In the structure of the front part of the vehicle body, there is known a structure in which the left side stay, the right side stay, the lower cross member, the left upper side cross member, and the right upper side cross member of the dash panel are formed of resin. A metal upper beam is detachably connected to the upper ends of the left pillar and the right pillar. [0003] A hood locking device is installed in the center of the metal upper beam. The hood is held in the closed position by engaging a striker of the hood on the hood lock. [0004] In addition, the front end portion of the left upper beam is connected to the upper end portion of the left pillar, and the rear end portion of the left upper beam is ...
