Description

  The present invention relates to a vehicle body front structure including a radiator grille that is attached to an attachment hole formed in a front bumper that constitutes a front surface of a vehicle body, and a radiator grille cover that is attached to the back side of the radiator grille.

  A radiator for cooling the engine is arranged in the engine room at the front of the vehicle body, and the front bumper constituting the front surface of the vehicle body serves as an outside air intake for taking in air (outside air) for cooling the radiator. A radiator grill (also called a front grill) is arranged (for example, Patent Document 1). Since this radiator grill is disposed at a position where it can be easily observed at the front part of the vehicle body, it also functions as a decorative member that becomes a part of the design of the vehicle body.

JP 2009-6900 A

  Incidentally, in general, a horn (also referred to as a horn) is disposed on the rear side of the front bumper at the front of the vehicle body. The horn sound from the horn is propagated outside the vehicle through an opening formed in the radiator grill as an outside air inlet. Such a horn may also function as an alarm device for preventing theft of the vehicle. In this case, a horn harness connected to the horn (hereinafter referred to as a harness) is inserted by inserting a blade from the opening of the radiator grille. The function of the horn as an alarm device may be lost.

  As a means for solving the above problems, it is conceivable to seal an opening near the horn in the radiator grill. However, with this method, the area of the outside air intake port for taking in air for cooling the radiator is reduced, so that the cooling performance of the radiator may be lowered. As another method, a method of adding a horn or changing to a high-output horn is conceivable. However, this method causes a significant increase in cost.

  Further, in the radiator grill, the vehicle body structural member painted in the vehicle body color and disposed in the engine room is observed from the opening which is the outside air intake port, and the appearance quality is deteriorated. As a method for solving this problem, a region that can be observed from the opening of the radiator grille is painted black in the vehicle body structural member. However, this method increases the number of steps and increases the manufacturing cost. As another method, it is conceivable to install a black outfitting part in an area that can be observed from the opening of the radiator grille in the vehicle body structural member. However, this method causes an increase in cost and a radiator. Whether or not the assembling parts need to be assembled depends on the design (shape) of the grill. In other words, since it is necessary to assemble the parts, the burden on the worker on the production line is increased, which causes erroneous assembly.

  In view of such a problem, the present invention provides a vehicle body front structure capable of preventing the cutting of the harness and the deterioration of the appearance quality without incurring problems in manufacturing and performance and increasing the cost. It is an object.

  In order to solve the above-mentioned problems, a typical configuration of the vehicle body front structure according to the present invention includes a radiator grille that is attached to a mounting hole formed in a front bumper that constitutes the front surface of the vehicle body, and a radiator grille that is attached to the rear side of the radiator grille A radiator grille cover that includes a horn harness that extends downward, and is further provided with a horn that is disposed in the vicinity of the mounting hole at the rear of the front bumper and outputs a horn sound. A grill outer frame that has a shape corresponding to the shape of the mounting hole of the bumper and constitutes the outer periphery of the radiator grille, and extends vertically between the upper wall and the lower wall of the grill outer peripheral frame so as to create a space in the grill outer frame. The radiator grille cover has a width equal to that of the grill outer peripheral frame in the vehicle width direction. The outer periphery of the cover and the outer periphery of the cover are arranged at the same position as the vertical wall of the grille in the vehicle width direction and extend vertically between the upper and lower walls of the outer periphery of the cover to divide the space in the outer periphery of the cover The side wall near the horn of the side walls of the cover outer peripheral frame has a vehicle width and the cover vertical wall adjacent to the side wall near the horn in a horizontal sectional view. It crosses the straight line which connects the front end of the grill vertical wall arrange | positioned in the same position in the direction, and the horn harness, and is further extended to back.

  According to the above configuration, the space from the outer peripheral frame of the grill, that is, the path from the opening serving as the outside air inlet to the horn harness is blocked by the cover vertical wall disposed in the vicinity of the horn harness. Thereby, even if a cutter is inserted from the space (opening) in the outer peripheral frame of the grill, it is possible to prevent the cutter from reaching the horn harness and prevent the horn harness from being cut.

  Moreover, if it is the said structure, since the space (opening part) of the vicinity of a horn harness is not block | closed in a grill outer periphery frame, the area of an external air intake will not be reduced. Therefore, it is possible to prevent the cooling performance of the radiator from being lowered and to prevent the occurrence of problems in performance. In addition, since the horn sound from the horn does not interfere with the propagation of the horn, the horn harness can be prevented from being cut at a low cost without incurring additional costs such as adding a horn or changing to a high-output horn. Is possible.

  In order to solve the above-described problems, another configuration of the vehicle body front structure according to the present invention is a radiator grille that is attached to an attachment hole formed in a front bumper that constitutes the front surface of the vehicle body, and is attached to the rear side of the radiator grille. A vehicle body front structure including a radiator grille cover, further comprising a vehicle body structural member disposed below the mounting hole at the rear of the front bumper and constituting a skeleton in the vehicle width direction at the vehicle body front. A grill outer peripheral frame having a shape corresponding to the shape of the mounting hole of the bumper and constituting the outer periphery of the radiator grille, and a plurality of grills extending laterally between both side walls of the grill outer peripheral frame to divide the space in the grill outer peripheral frame The radiator grille cover has the same width as the grille outer peripheral frame in the vehicle width direction and constitutes the outer periphery of the radiator grille cover The lower wall of the cover outer peripheral frame is disposed at the same position as the lower wall of the grill outer peripheral frame in the vehicle body height direction or below the lower wall of the grill outer peripheral frame, and is perpendicular to the side of the vehicle body. , The front end extends forward from a position where it intersects the straight line connecting the rear end of the lower wall of the grill outer peripheral frame and the upper front end of the vehicle body structural member, and the rear end extends to the lower wall of the grill outer peripheral frame. It intersects with a straight line connecting the front end of the adjacent grill horizontal wall and the rear end of the upper part of the vehicle body structural member, and further extends to the rear.

  According to the above configuration, the field of view from above the radiator grille is blocked by the lower wall of the cover outer peripheral frame, and the vehicle body structural member cannot be observed from the outside. Therefore, it is possible to maintain good appearance quality without increasing the number of processes and costs. In the above configuration, the radiator grille cover is attached to the radiator grille. Therefore, it is possible to prevent erroneous assembly that has occurred when the outfitting parts are attached to the vehicle body as in the prior art.

  Further, as described above, the lower wall of the cover outer peripheral frame extends in the longitudinal direction of the vehicle body, so that air flowing from the opening portion of the radiator grill to the front portion of the vehicle body is rectified. Thereby, the air which flowed into the vehicle body front part can be efficiently blown to the radiator, and the cooling performance can be improved.

  It is preferable that the radiator grill has an emblem mounting portion to which an emblem is attached on the front surface, and the radiator grill cover is attached to the radiator grill at least on the back side of the emblem mounting portion. According to this configuration, the rigidity of the emblem mounting portion in the radiator grill can be improved. Thereby, it becomes possible to suppress the deformation of the radiator grille due to the contact with the emblem.

Thereby, the space in the grill outer peripheral frame 152 is divided into three rows in the vehicle body height direction.

  That is, in the radiator grill 150 of this embodiment, the space in the grill outer peripheral frame 152 is divided into 30 small spaces by the grill vertical walls 154a to 154i and the grill horizontal walls 156a and 156b. The 30 small spaces function as openings serving as outside air intakes, and air for cooling the radiator 140 is taken into an engine room (not shown).

  Further, an emblem mounting portion 158 is provided on the front surface of the radiator grill 150. When the emblem 170 is attached to the emblem mounting portion 158, the state shown in FIG. On the other hand, the radiator grill cover 160 is attached to the back surface of the radiator grill 150 as described above.

  As shown in FIG. 3A, the radiator grill cover 160 has an outer periphery constituted by a cover outer peripheral frame 162 having a width equal to the grill outer peripheral frame 152 in the vehicle width direction. In the vehicle body height direction of the cover outer peripheral frame 162, the upper wall 162a is positioned at the same height as the grill horizontal wall 156b of the grill outer peripheral frame 152, and the lower wall 162b is the same height as the lower wall 152b of the grill outer peripheral frame 152. Located in. That is, the radiator grill cover 160 has substantially the same height as that from the grill horizontal wall 156b to the lower wall 152b of the radiator grill 150 in the vehicle body height direction.

  In the present embodiment, the radiator grille cover 160 has an upper wall 162a of the cover outer peripheral frame 162 at the same position as the grille vertical walls 154b, 154c, 154g, and 154h among the plurality of grille vertical walls 154a to 154i in the vehicle width direction. And a plurality of (four in this embodiment) cover vertical walls 164a to 164d extending in the vertical direction between the lower wall 162b and the lower wall 162b. Thereby, the space in the cover outer peripheral frame 162 is divided into six rows in the vehicle width direction.

  In this embodiment, the radiator grill 150 has a structure having nine grill vertical walls and two grill horizontal walls, and the radiator grill cover 160 has four cover vertical walls. However, the present invention is not limited to this. The number of the vertical grill walls and the horizontal grill walls of the radiator grill 150 and the vertical cover walls of the radiator grill cover 160 can be changed as appropriate.

  4 is a schematic cross-sectional view of FIG. 2 (b), FIG. 4 (a) is a cross-sectional view taken along the line BB of FIG. 2 (b), and FIG. 4 (b) is a cross-sectional view of FIG. 4C is a cross-sectional view taken along the line CC, and FIG. 4C is a cross-sectional view taken along the line C′-C ′ illustrating a conventional configuration as a comparative example that does not include the radiator grill cover 160. Here, as described above, the horn 142 is installed in the vehicle body front structure 100 of the present embodiment (see FIG. 1). When the horn 142 is disposed in the vicinity of the mounting hole 110a behind the front bumper 110 as shown in FIG. 2B, a blade (not shown) is inserted between the grill vertical walls 154a and 154b. The harness 142a (see FIG. 1) may be cut.

  Therefore, in the present embodiment, in order to prevent the above-described cutting of the harness 142a, the side wall 162c in the vicinity of the horn 142 (see FIG. 2B) of the side walls 162c and 162d (both side walls) of the cover outer peripheral frame 162 is attached to the vehicle body. Extends backwards. Specifically, in the cover outer peripheral frame 162, the side wall 162c near the horn 142 has a cover vertical wall 164a adjacent to the side wall 162c and a vehicle width direction in a horizontal sectional view as shown in FIG. And extends from the position P1 intersecting with a straight line 200a (shown by a broken line in FIG. 4A) connecting the front end of the grill vertical wall 154b disposed at the same position and the harness 142a. That is, the side wall 162c in the vicinity of the horn 142 is set to such a length that the harness 142a cannot be seen from between the grill vertical walls 154a and 154b (opening) of the radiator grill 150 (strictly, the grill outer peripheral frame 152).

  According to the above configuration, the side wall 162c near the horn 142 serves as a baffle plate, and the path from the grill vertical walls 154a and 154b (opening) of the grill outer peripheral frame 152 to the harness 142a is blocked. Therefore, even if the blade is inserted in the direction of the arrow D1 (shown by a one-dot chain line in FIG. 4A) from between the grill vertical walls 154a and 154b (opening), the blade cannot reach the harness 142a. The cutting can be prevented.

  Further, the shield plate 192 (shown by a two-dot chain line in FIG. 4A) that is conventionally installed as a measure for preventing the harness 142a from being cut is provided between the grill vertical walls 154a and 154b of the grill outer peripheral frame 152 (opening). Part) is blocked, but if it is the configuration of this embodiment, it will not be blocked. Therefore, since the area of the outside air intake is not reduced, it is possible to prevent the cooling performance of the radiator 140 from being lowered and to avoid occurrence of problems in performance. In addition, since the transmission of the horn sound from the horn 142 to the outside of the vehicle is not hindered, it is possible to prevent the harness 142a from being cut at a low cost without requiring an additional horn 142 or a change to a high output horn. It is.

  Here, as described above, in the vehicle body front structure 100, a plurality of vehicle body structural members (hood lock member 122, hood lock brace 124, lamp support braces 126a and 126b, lamp support members 128a,. 128b, apron side members 130a and 130b, a front lower cross member 132, and a front bumper member 134) are formed (see FIG. 1). Of these vehicle body structural members, the front lower cross member 132, which is a vehicle body structural member disposed behind the front bumper 110 and below the mounting hole 110a, may be painted in the body color. Deterioration of the appearance quality due to the member 132 being observed (viewed) from the outside, that is, the opening of the radiator grill 150, has been a problem.

  Therefore, in the present embodiment, in order to prevent the front lower cross member 132 from being visually recognized from the opening of the radiator grill 150 described above, particularly the opening between the grill lateral wall 156b and the lower wall 152b of the grill outer peripheral frame 152, The lower wall 162b of 162 is extended toward the vehicle body longitudinal direction.

  Specifically, the front end of the lower wall 162b of the cover outer peripheral frame 162 is the rear end of the lower wall 152b of the grill outer peripheral frame 152 in a vertical sectional view on the side of the vehicle body as shown in FIG. Extends forward from a position P2 that intersects a straight line 200b (shown by a broken line in FIG. 4B) that connects the front lower cross member 132 (the vehicle body structural member) to the front end of the upper portion. On the other hand, the rear end of the lower wall 162b of the cover outer peripheral frame 162 is adjacent to the lower wall 152b of the grill outer peripheral frame 152 in a vertical sectional view on the side of the vehicle body as shown in FIG. It extends rearward from a position P3 that intersects a straight line 200c (shown by a broken line in FIG. 4B) connecting the front end of the lateral wall 156b and the rear end of the upper portion of the front lower cross member 132 (vehicle body structural member). That is, the lower wall 162b of the cover outer peripheral frame 162 is set to such a length that the front lower cross member 132 that is a vehicle body structural member cannot be seen from the opening of the radiator grill 150 (strictly, the grill outer peripheral frame 152).

  According to the above configuration, the lower wall 162b of the cover outer peripheral frame 162 serves as a baffle plate, and the direction of the arrow D2 from the opening between the grill lateral wall 156b and the lower wall 152b of the grill outer peripheral frame 152 of the radiator grill 150 (FIG. 4 ( The field of view (shown by the alternate long and short dash line in b) and (c) is blocked. Therefore, the front lower cross member 132 cannot be observed from the outside, and good appearance quality can be maintained.

  Further, when the shielding plate 194 (shown by a two-dot chain line in FIG. 4C) that has been conventionally installed as a measure for preventing the front lower cross member 132 from being visually recognized, the grill horizontal wall 156b and the lower wall 152b of the grill outer peripheral frame 152 are used. (Opening) is blocked, but if it is the configuration of the present embodiment, it is not blocked. Therefore, as described above, it is possible to prevent a decrease in the area of the outside air intake, and to avoid a decrease in the cooling performance of the radiator 140 and a malfunction in performance.

  Furthermore, according to the configuration of the present embodiment, in order to prevent the front lower cross member 132 from being visually recognized, the conventional upper surface 132a (see FIG. 4C) of the front lower cross member 132 or the front lower cross member has been used. It is not necessary to install the fitting component 196 (see FIG. 4C) on the upper surface 132a of the 132. Therefore, it is possible to prevent the front lower cross member 132 from being visually recognized at a low cost without causing an increase in the number of parts and processes, and hence an increase in costs associated therewith.

  Further, as described above, the lower wall 162b of the cover outer peripheral frame 162 extends in the longitudinal direction of the vehicle body, so that it flows from the opening of the grill outer peripheral frame 152 (radiator grill 150) as shown in FIG. Among the air 202a to 202c (illustrated by solid lines), the lower air 202c is rectified, and the downward diffusion of the air inside the radiator grill 150 is prevented. Also, as shown in FIG. 4B, the radiator grill cover 160 is disposed behind the radiator grill 150, so that the upper layer air 202a is rectified by the upper wall 162a of the cover outer peripheral frame 162, and the radiator grille. The upward diffusion of air inside 150 is also prevented.

  Therefore, as shown in FIG. 4C, the radiator grill cover 160 is provided behind the radiator grill 150 (the grill outer peripheral frame 152) as shown in FIG. 4C. The air 202a and 202c that has passed through the radiator grill 150 when there is no air is prevented from diffusing upward and downward, and the air that has flowed into the radiator grill 150 (the front of the vehicle body) is efficiently blown to the radiator 140 (see FIG. 1). can do. Therefore, the cooling performance of the radiator 140 can be improved.

  In the present embodiment, the configuration in which the lower wall 162b of the cover outer peripheral frame 162 is positioned at substantially the same height as the lower wall 152b of the grill outer peripheral frame 152 is illustrated, but the present invention is not limited to this. It may be located below the lower wall 152b. However, the configuration in which the lower wall 162b of the cover outer peripheral frame 162 is located above the lower wall 152b of the grill outer peripheral frame 152 is desirably avoided because it is difficult to obtain the effect of preventing the above-described front lower cross member 132 from being visually recognized.

  FIG. 5 is a schematic cross-sectional view of FIG. 2A, FIG. 5A is a cross-sectional view taken along line AA of FIG. 2A, and FIG. 5B includes a radiator grill cover 160. It is A'-A 'sectional drawing which illustrates the conventional structure as a comparative example which does not exist. As shown in FIG. 5 (a), in the radiator grill 150 of the present embodiment, recesses 159a and 159b are formed on the back side of the side walls 152c and 152d in the grill outer peripheral frame 152, respectively, and the back side of the emblem mounting part 158 A recess 159c is formed in the upper surface. On the other hand, as shown in FIG. 5A, in the radiator grill cover 160, insertion holes 169a, 169b, and 169c are formed in the cover outer peripheral frame 162 at positions corresponding to the recesses 159a to 159c of the grill outer peripheral frame 152. ing.

  Then, the radiator grill cover 160 is attached to the radiator grill 150 by inserting the fastening member 190c into the recesses 159c and 169c. Thereafter, the fastening members 190a and 190b are inserted into the recesses 159a and 159b and the insertion holes 169a and 169b, whereby the radiator grill 150 to which the radiator grill cover 160 is attached is attached to the front bumper 110 as shown in FIG. That is, in the vehicle body front structure 100 of the present embodiment, the radiator grill 150 having the radiator grill cover 160 attached to the back side is attached to the attachment hole 110a of the front bumper 110.

  Here, as in the prior art, when the fitting component 196 is installed on the upper surface 132a of the front lower cross member 132, that is, on the vehicle body side (see FIG. 4C), the fitting component 196 depends on the design (shape) of the radiator grill 150. When the necessity of assembling is divided (when it becomes necessary to assemble the parts), an operator working on the production line determines whether the assembling parts 196 are necessary according to the shape of the radiator grill 150. You must judge. As a result, the burden on the operator increases and there is a risk of erroneous assembly.

  On the other hand, in the present embodiment, as described above, the radiator grille is provided with the recess 159c and the insertion hole 169c provided in the grill outer peripheral frame 152 and the cover outer peripheral frame 162, that is, the mounting structure provided in the radiator grill 150 and the radiator grill cover 160. The radiator grill 150 having the cover 160 attached to the back side is attached to the attachment hole 110a of the front bumper 110. With such a configuration, the worker can immediately recognize that the radiator grill cover 160 needs to be attached to the radiator grill 150 by forming the recess 159c in the grill outer peripheral frame 152 of the radiator grill 150. It is. Therefore, the operator can easily determine whether or not the radiator grille cover 160 needs to be assembled, so that the burden on the operator can be reduced and the vehicle body side (front lower cross member 132) can be reduced as in the prior art. It is possible to prevent erroneous assembly that occurred when the outfitting component 196 was attached.

  In particular, in the present embodiment, the radiator grill cover 160 is attached to the back side of the emblem mounting portion 158 in the radiator grill 150 by the recess 159c of the grill outer periphery frame 152 and the cover outer peripheral frame 162 169c shown in FIG. Thereby, the rigidity of the emblem mounting part 158 in the radiator grill 150 can be improved. Accordingly, in the configuration without the radiator grill cover 160 as shown in FIG. 5 (b), the radiator grill cover 160 generated when the force 204 for pushing the radiator grill 150 to the rear of the vehicle body due to the contact with the emblem 170 is applied. It is possible to suppress deformation due to bending (illustrated by a broken line in FIG. 5B).

  Further, in the present embodiment, as shown in FIG. 3B, a rib 180 is formed below the vicinity of the insertion hole 169c in the cover outer peripheral frame 162. Accordingly, the standing walls 182a and 182b in the vicinity of the insertion hole 169c can be prevented from being deformed in the directions of the arrows 206a and 206b, that is, in the direction in which the standing walls 182a and 182b are separated from each other. It is possible to improve the strength of 160.

  As described above, according to the vehicle body front structure 100 according to the present embodiment, the side wall 162c near the horn 142 of the side walls 162c and 162d (both side walls) of the cover outer peripheral frame 162 is directed toward the rear of the vehicle body. By extending, it can function as a baffle plate and can prevent the harness 142a from being cut. Further, by extending the lower wall 162b of the cover outer peripheral frame 162 in the longitudinal direction of the vehicle body, the front lower cross member 132, which is a vehicle body structural member disposed behind the front bumper 110 and below the mounting hole 110a, is prevented from being visually recognized. And good appearance quality can be maintained.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
