  A front end panel is installed in front of the engine room. The front end panel has a center panel formed in a flat plate shape as a main part due to formability and load transmission in the vertical direction, and a radio core support upper that protrudes forward from the upper end is formed along the vehicle width direction Has been. The center panel and the radio core support upper are integrally formed of synthetic resin, and a heat exchanger such as a radiator or a condenser is held on the front surface of the center panel. Therefore, a fan opening for allowing air to pass through is formed in the center panel, and an electric fan is attached thereto.

An openable / closable hood is provided above the front end panel. A striker protrudes from the lower surface of the hood, and a hood lock that engages with the striker is attached to the upper portion of the front end panel. This hood lock is attached to the hood lock attachment part set on the radio core support upper in an upward state, and engages with a striker pushed down from the upper side vigorously to maintain the closed state of the hood (for example, Patent Documents) 1).
Japanese Patent Laid-Open No. 10-329756 (FIG. 2)

  However, in such a conventional technique, since the hood lock mounting part is set to the radio core support upper protruding forward from the upper end of the center panel, the hood lock attached to the hood lock mounting part is connected to the hood lock. When a downward hood lock load is applied from the striker, the load is concentrated at the base of the radio core support upper. Therefore, conventionally, in order to increase the rigidity of the base portion of the radio core support upper, it is necessary to make the base portion thick or add a reinforcing rib, which complicates the structure of the front end panel.

  The present invention has been made paying attention to such a conventional technique, and provides a front end panel capable of reliably receiving a hood lock load with a simple structure.

The invention according to claim 1 is a structure having a flat center panel in which two circular fan openings are formed on the left and right sides, and a radio core support upper formed to project forward from the upper end of the center panel. A front end panel in which a hood lock mounting part for mounting a hood lock is set above, wherein the front and rear positions of the hood lock mounting part are set behind the general surface of the center panel, and the hood right relationships and hierarchical relation is set in the lock installation site is above the intermediate portion of the fan opening with a top portion that avoids and the fan opening avoiding recess of the start of the striker in the center panel, the center left and right end positions of surrounding the hood lock on the rear surface of the panel is made by forming a first rib formed by extending in the vertical, The lower end position of the first rib, it forms a second rib formed by extending in the left and right, between the lower end and the second ribs of the hood lock installation site, it is extended in the vertical comprising third made by forming a rib, the rear surface of the fan opening does is not formed a center panel, characterized by comprising forming a reinforcing rib which is connected to the second rib.

According to the second aspect of the present invention, a cosmetic cover panel having a portion projecting rearward from the center panel is formed above the radio core support upper, and at a position corresponding to the hood lock mounting portion of the cover panel. A notch for exposing the hood lock is formed.

  According to the first aspect of the present invention, since the hood lock attachment portion is installed on the rear surface of the center panel, the hood lock load is not applied to the radio core support upper, and it is not necessary to reinforce the base portion of the radio core support upper. Therefore, the structure of the front end panel is not complicated. Further, since the hood lock mounting part is on the rear side, it is not necessary to form a notch in the radio core support upper protruding forward of the center panel, and the rigidity of the radio core support upper can be prevented from being lowered. Furthermore, since there is no fan opening below the hood lock mounting portion, the hood lock load is transmitted straight to the lower end of the center panel and is distributed from there to the vehicle body.

In addition , each of the two fan openings is circular, and the hood lock mounting part is set at the upper position between the left and right intermediate parts. Therefore, the center panel area located between the left and right fan openings serves as a transmission path for the hood lock load. The hood lock load is reliably transmitted to the lower end of the center panel. Moreover, since the fan opening is circular, the center panel region in the middle is wide in the vertical direction, and the hood lock load transmission / dispersion performance is high.

In addition , since the first, second, and third ribs are formed around the hood lock mounting area, even if a downward hood lock load is applied to the hood lock that is mounted on the hood lock mounting area, these ribs are used to transfer these loads. I can take it. Therefore, the burden applied to the hood lock mounting portion can be reduced, and the hood lock mounting portion can be protected. In particular, since the load can be released to the reinforcing rib by the third rib formed between the lower end of the hood lock attachment portion and the second rib, the load can be dispersed.

According to the second aspect of the present invention, the cutout for exposing the hood lock is formed in the cover panel even in the structure in which the cover cover for makeup is formed above the radio core support upper. Thus, the hood lock and the striker can be reliably engaged. Further, even if such a notch is formed in the cover panel, the cover panel itself is an appearance countermeasure member and is not formed to ensure rigidity, and therefore does not affect the overall rigidity of the front end panel.

For the purpose of providing a front end panel that can reliably receive a hood lock load with a simple structure, a flat center panel having two circular fan openings formed on the left and right sides, and an upper end of the center panel. A front end panel having a hood lock mounting portion for mounting a hood lock on the upper side, wherein the front and rear positions of the hood lock mounting portion are set in a structure having a radio core support upper protruding forward , said a rear than the general plane of the center panel, the hood lock setting right relationships and hierarchical relation is the attachment site, at the top of which in the center panel avoided and the fan opening avoiding recess entering the striker And a position above the middle of the fan opening, and a hood lock on the rear surface of the center panel. The left and right end positions of surrounding the made by forming a first rib formed by extending in the vertical, the lower end position of the first rib, a second rib formed by extending in right and left and it will have, between the second rib and the lower end of said hood lock installation site, be formed a third rib formed by extending in the vertical rear surface of the center panel the fan does openings are formed the, by obtained by forming a reinforcing rib connected between the second rib and realized.

  A preferred embodiment of the present invention will be described below with reference to FIGS. The front end panel 1 is disposed in front of a well-known engine room (not shown) and is an integrally molded product made of synthetic resin. The front end panel 1 has a rectangular and flat center panel 2. From the upper end of the center panel 2, a radio core support upper 3 protruding forward is formed along the vehicle width direction.

  Further, at the lower end of the center panel 2, a radio core support lower 4 having a reverse T-shaped cross section protruding forward and backward is formed. Further, side wall portions 5 are formed on the left and right ends of the center panel 2 so as to protrude forward. The periphery of the center panel 2 has a three-dimensional shape by the above-described radio core support upper 3, the radio core support lower 4, and the side wall portion 5, and the overall rigidity is ensured.

  Overhang portions 6 are formed on the left and right sides of the side wall portion 5. The overhanging portion 6 is formed with a fastening portion 8 having a U-shaped cross section, and the front end of the side member 7 is fixed thereto. Further, above the radio core support upper 3, a cover panel 9 having a T-shaped cross section projecting forward and rearward of the center panel 2 and being longer on the left and right sides than the radio core support upper 3 is formed. This cover panel 9 is connected with a plurality of vertical ribs R, R,... Between the radio core support upper 3 and hides the structure of the upper part of the center panel 2, and is not expected in terms of strength. Absent. Further, an opening P penetrating in the front-rear direction is formed between the cover panel 9 and the radio core support upper 3.

  A radiator 10 that circulates engine coolant and cools it with air is assembled in front of the center panel 2. Therefore, the center panel 2 is formed with two fan openings 11 arranged side by side for allowing air to pass therethrough. A stay 12 is formed behind the fan opening 11, and an electric fan (not shown) for forcibly sucking air is attached to the stay 12.

  An openable / closable hood 13 is provided at the upper part of the engine room where the front end panel 1 is installed. A striker 14 is attached downward on the lower surface of the front end of the hood 13, and a hood lock 15 that is engaged with the striker 14 and holds the closed state of the hood 13 is attached to the front end panel 1 side.

The hood lock 15 is attached to the hood lock attachment portion 16 set on the rear surface of the upper end portion of the center panel 2 by screw means (not shown) from the rear side or the front side. Therefore, the radio core support upper 3 at the hood lock attachment part 16 is in a state of being lifted upward from the general part, and the vertical height of the opening P at that part is also small. The hood lock attachment portion 16 is set at a position where the concave portion 21 into which the striker 14 enters at the upper part of the center panel 2 protrudes to the rear side from the general surface 23 formed on the front side and the fan opening 11 does not exist on the lower side. Has been. First and second ribs 17 extending vertically are formed at the left and right ends of the position surrounding the hood lock 15 on the rear surface of the center panel 2. forming a second rib 17a formed by extending in it, between the lower end and the second rib 17a of the hood lock mounting site 16 forms a third rib 22 formed by extending in the vertical It becomes Te, wherein the rear surface of the center panel 2 fan opening 11 is not formed, by forming a reinforcing rib 18 'which is connected to the second rib 17a.

  The hood lock attachment portion 16 is located directly above the intermediate portion between the two fan openings 11. Accordingly, the fan opening 11 does not exist below the hood lock mounting portion 16, and the center panel 2 continues to the radio core support lower 4 in the vertical direction. In addition, on the front surface of the center panel 2, the reinforcing ribs 18 having a sealing function that surrounds a middle portion of the left and right fan openings 11 and a rectangular shape that approximates a linear shape and a radiator shape that are continuous in the vertical direction on the left and right sides, respectively. Reinforcing ribs 19 are formed. A reinforcing rib 18 ′ extends from the lower end of the second rib 17 a to the radio core support lower 4 through the middle portion of the left and right fan openings 11 at the same position as the reinforcing rib 18 on the rear surface of the center panel 2. .

  A notch 20 for exposing the hood lock 15 is formed at a position corresponding to the hood lock attachment portion 16 of the cover panel 9. By this notch 20, the hood lock 15 and the striker 14 can be engaged. Even if such a notch 20 is formed in the cover panel 9, the cover panel 9 itself is an appearance countermeasure member and is not formed to ensure rigidity, and therefore affects the overall rigidity of the front end panel 1. Absent.

  Further, regarding the radio core support upper 3, since the hood lock 15 is attached to the rear surface of the center panel 2, it is not necessary to process the radio core support upper 3 with a notch or the like. In this way, the process of removing a part of the radio core support upper 3 is not performed for the radio core support upper 3 that plays an important role in rigidity in the front end panel 1 and its peripheral structure. preferable.

  When the striker 14 of the hood 13 that is closed with force is engaged with the hood lock 15 with respect to the hood lock 15 attached in the above-described state, the impact when the hood lock 15 is closed serves as a downward hood lock load F. To join. First, the hood lock 15 is pushed downward by the hood lock load F. The hood lock 15 is not only transmitted to the first rib 17, the second rib 17a and the reinforcing rib 18 ', but also received and held. Since the lower end portion of the third rib 22 is supported to support the hood lock mounting portion 16 from the lower side, the first rib 17, the second rib 17a and the hood lock mounting portion 16 generate the hood lock load F. I can take it.

  The hood lock load F applied to the hood lock 15 is transmitted as it is to the radio core support lower 4 using the intermediate region between the left and right fan openings 11 as a transmission path (path along the central reinforcing rib 18 '). Since the fan opening 11 is circular, the middle region has a wide vertical width, and the transmission / dispersion performance of the hood lock load F is high.

  Moreover, since the fan opening 11 does not exist in this transmission path, the hood lock load F is transmitted straight to the radio core support lower 4, and is then distributed to the vehicle body via the radio core side wall portion 5 and the radio core fastening portion 8. . Thus, since the hood lock load F is directly applied only to the center panel 2 and not to the radio core support upper 3, it is not necessary to reinforce the base portion of the radio core support upper 3 as in the prior art. The overall structure of the panel 1 can be simplified.

  In the above embodiment, the example in which the two fan openings 11 are formed in the center panel 2 has been described, but only one may be formed on either the left or right side.
