JP 2008-100533 A JP 2010-023536 A

  It is an object of the present invention to provide a technique capable of easily forming a windshield lower panel having a complicated three-dimensional shape and sufficiently increasing the rigidity of the entire windshield lower panel. Let it be an issue.

  According to the first aspect of the present invention, a dashboard lower panel that partitions the compartment and the front of the compartment, and a windshield lower panel that is provided on the dashboard lower panel and supports the lower end of the windshield, The windshield lower panel includes a lower panel body that is overlapped and welded to an upper edge of the dashboard lower panel, and a lower panel upper surface portion that is overlapped and welded to the upper edge of the lower panel body. The lower panel upper surface portion is a substantially flat member inclined forward and downward so as to support the lower end portion of the windshield, and the lower panel upper surface portion is opposed to the upper edge of the lower panel body. A welding line welded in the vehicle width direction is a first welding line, and the lower edge of the dashboard lower panel is A welding line that welds the lower edge of the panel body in the vehicle width direction is a second welding line, and the first welding line is more forward of the vehicle body than the second welding line at the vehicle width central portion of the upper surface of the lower panel. A vehicle body front portion structure is provided, wherein the first weld line is located behind the second weld line at both ends in the vehicle width direction of the upper surface portion of the lower panel. .

  As described in claim 2, preferably, a bead extending in the vehicle width direction is formed in the vicinity of the first weld line in the lower panel main body.

  As described in claim 3, more preferably, the bead is located at a vehicle width center portion.

  According to a fourth aspect of the present invention, preferably, in the upper surface portion of the lower panel, the width in the vehicle body front-rear direction that supports the windshield along the vehicle width direction is substantially the same, and both ends of the lower panel upper surface portion in the vehicle width direction are the same. The part is joined to the left and right front pillars.

  According to a fifth aspect of the present invention, preferably, the vertical wall of the lower panel body is formed with an opening through which the air conditioning apparatus intake duct passes, and the air conditioning apparatus intake duct penetrated through the opening. And the opening end of the air-conditioning apparatus intake duct is located in front of the vehicle body with respect to the vertical wall and the front end of the upper surface of the lower panel.

  In the invention according to claim 1, the windshield lower panel is constituted by two members, a lower lower panel main body and an upper lower panel upper surface. The lower panel body is overlaid and welded to the upper edge of the dashboard lower panel. The upper portion of the lower panel is overlapped and welded to the upper edge of the lower panel body. For this reason, it is possible to make the shape and size of the lower panel upper surface portion different from the shape and size of the lower panel main body. Even a windshield lower panel having a complicated three-dimensional shape can be easily formed.

  For example, the curvature of the lower panel body can be increased in order to increase the living space of the passenger compartment. Even in this case, it is possible to sufficiently support the lower end portion of the windshield, which is formed with a small curvature in response to a request in the design of the vehicle, by the upper surface portion of the lower panel. Therefore, it is possible to easily achieve the conflicting problems of expanding the living space of the passenger compartment and increasing the degree of freedom of vehicle design.

  Moreover, in the first aspect of the invention, the first weld line and the second weld line intersect each other when the vehicle body is viewed from above. The first weld line is a weld line for welding the upper surface of the lower panel to the upper edge of the lower panel body in the vehicle width direction. The second weld line is a weld line for welding the lower edge of the lower panel body in the vehicle width direction to the upper edge of the dashboard lower panel. That is, in the vehicle width center part of the upper surface part of the lower panel, the first welding line is located in front of the vehicle body with respect to the second welding line. At both ends in the vehicle width direction of the upper surface portion of the lower panel, the first weld line is located behind the vehicle body relative to the second weld line. For this reason, even if the overall shape of the windshield lower panel is a complicated three-dimensional shape, the upper and lower weld lines intersect in plan view, thereby reducing the rigidity (particularly bending rigidity) of the entire windshield lower panel. Can be raised enough.

  In the invention which concerns on Claim 2, the lower panel main body is formed with a bead extending in the vehicle width direction in the vicinity of the first weld line. For this reason, although the whole windshield lower panel is highly rigid, the lower panel main body can be deformed in the vertical direction with the bead as a base point. For example, when the collision object collides with the windshield or the lower panel upper surface from the outside of the vehicle, the lower panel main body can be effectively plastically deformed with the bead as a base point, thereby obtaining the characteristic of reducing the collision energy.

  In the invention which concerns on Claim 3, the bead is located in the vehicle width center part in the lower panel main body. The node of the windshield's amplitude due to running vibration is generally at the center of the vehicle width. The lower panel body can easily absorb the collision energy while suppressing vibrations by the bead portion located in the vehicle width center portion.

  In the invention according to claim 4, the width in the vehicle front-rear direction for supporting the windshield by the lower panel upper surface is substantially the same over the entire region in the vehicle width direction. In other words, the upper surface of the lower panel is wide in the longitudinal direction of the vehicle body so as to sufficiently support the windshield at any part from end to end in the vehicle width direction. By making it wide, a sufficient area for supporting the windshield by the upper surface of the lower panel can be secured. As a result, the windshield can be stably supported by the upper surface portion of the lower panel, and the attachment strength for attaching the windshield to the upper surface portion of the lower panel can be increased. In addition, the degree of freedom of the shape of the windshield can be increased.

  Furthermore, as described above, since the width in the longitudinal direction of the vehicle body is wide at both ends of the upper surface of the lower panel, it is possible to sufficiently secure a joining length for joining the both ends to the left and right front pillars by welding or the like. it can. Bonding strength for bonding the both end portions to the left and right front pillars is increased. As a result, the rigidity of the entire windshield lower panel can be efficiently secured.

  In the invention which concerns on Claim 5, the air-conditioner intake duct is penetrated and connected to the opening part formed in the vertical wall of the lower panel main body. For this reason, the periphery of the opening of the vertical wall is reinforced by the intake duct. Since the rigidity around the edge can be ensured, the shape of the opening of the vertical wall can be sufficiently retained.

  Furthermore, the intake portion of the intake duct can be shifted to the front of the vehicle body by the amount of the opening end of the intake duct located in front of the vehicle body with respect to the vertical wall of the lower panel body. By shifting the intake portion toward the front of the vehicle body, it is possible to arrange the intake duct while securing the living space of the passenger compartment.

  Furthermore, the opening end of the intake duct is located in front of the vehicle body with respect to the front end of the upper portion of the lower panel. That is, the position of the front end of the lower panel upper surface portion may be a position where the lower end portion of the windshield can be supported without extending more forward than necessary. The width of the lower panel upper surface in the vehicle longitudinal direction can be easily set to a minimum size that can support the lower end of the windshield.

  EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated below based on an accompanying drawing. "Front", "Rear", "Left", "Right", "Up", "Down" follow the direction seen from the driver, Fr is front, Rr is rear, Le is left, Ri is right , CL indicates the center of the vehicle width.

  The vehicle body front structure according to the embodiment will be described. As shown in FIGS. 1 to 3, the vehicle 10 is, for example, a passenger car, and a front chamber 12 and a vehicle compartment 13 positioned immediately behind the front chamber 12 are formed inside the vehicle body 11. The vehicle body 11 comprises a monocoque body. The front chamber 12 is configured as a power unit housing chamber for housing a power unit such as an engine (not shown), for example, and an upper opening is covered with a hood 14 that can be opened and closed. The front chamber 12 may be other than the power unit accommodation chamber.

  The front half of the vehicle body 11 includes left and right front pillars 21L and 21R, a dashboard lower panel 22, a windshield lower panel 23, and a dashboard upper panel 24.

  As shown in FIGS. 2 and 3, the dashboard lower panel 22 is a member constituting the front wall of the vehicle interior 13. That is, the dashboard lower panel 22 is a vertical plate-like member that partitions the front chamber 12 and the vehicle compartment 13 and has an upper edge 22a (upper flange 22a) that is bent rearward and upward from the upper end.

  The windshield lower panel 23 is a member that is provided on the dashboard lower panel 22 and supports the lower end portion 25 a of the windshield 25.

  The dashboard upper panel 24 is a member having a substantially L-shaped cross section that extends forward from the space between the upper end of the dashboard lower panel 22 and the lower end of the windshield lower panel 23. That is, the dashboard upper panel 24 is located in front of the windshield lower panel 23.

  The windshield lower panel 23 and the dashboard upper panel 24 form a cowl box 26 having a substantially U-shaped cross section. The cowl box 26 is formed in the shape of a rain gutter that is elongated in the vehicle width direction, and is a flow path of rainwater that has flowed from the windshield 25, and stores a wiper unit (not shown). The open end of the upper portion of the cowl box 26 is covered with a cowl top grill 27.

  Next, the windshield lower panel 23 will be described in detail. As shown in FIGS. 2 to 4, the windshield lower panel 23 includes a lower panel main body 30 and a lower panel upper surface portion 40.

  When the vehicle body 11 is viewed from above, the dashboard lower panel 22, the windshield 25, and the lower panel body 30 are gently curved so as to protrude forward of the vehicle body. Furthermore, in order to enlarge the living space of the passenger compartment 13, the curvature of the dashboard lower panel 22 and the curvature of the lower panel body 30 are set to be relatively large. On the other hand, the curvature of the windshield 25 is set to be smaller than that of the lower panel body 30 in response to a request in the design of the vehicle 10. With respect to the lower panel main body 30, the lower end portion 25 a of the windshield 25 having different curvatures can be supported by the lower panel upper surface portion 40.

  The lower panel main body 30 is a vertical plate-like member provided on the dashboard lower panel 22 and extends generally upward from above the dashboard lower panel 22. The width dimension of the lower panel body 30 in the vehicle width direction substantially matches the width dimension of the dashboard lower panel 22 in the vehicle width direction. The lower panel body 30 includes a vertical plate-shaped vertical wall 31, a lower edge 32 (lower flange 32) bent backward from the lower end, and an upper edge 33 (upper flange 33) bent rearward and upward from the upper end. , Consisting of.

  On the upper surface of the upper edge 22a of the dashboard lower panel 22, a rear end portion of the dashboard upper panel 24 and a lower edge 32 of the lower panel body 30 are overlapped in this order and welded together. That is, the lower edge 32 of the lower panel body 30 is overlapped with the upper edge 22a of the dashboard lower panel 22 and is welded.

  The lower panel upper surface portion 40 is a substantially flat plate member that is inclined forward and downward so as to support the lower end portion 25 a of the windshield 25. A lower end portion 25a of the windshield 25 is joined to the upper surface of the lower panel upper surface portion 40 by a sealing agent (adhesive). The lower panel upper surface portion 40 is overlapped and welded to the upper edge 33 of the lower panel main body 30. The width of the windshield 25 is smaller than the width of the dashboard lower panel 22. Therefore, the width of the lower panel upper surface portion 40 for supporting the windshield 25 (the size between the vehicle width direction both end portions 41L and 41R) is smaller than the width of the dashboard lower panel 22. The lower panel upper surface portion 40 has a flange 43 extending forward from the front end 42. The rear end portion of the cowl top grill 27 (see FIG. 3) is clipped to the flange 43.

  In the lower panel upper surface portion 40, the width Wi (see FIG. 2) in the vehicle longitudinal direction for supporting the windshield 25 along the vehicle width direction is substantially the same throughout the vehicle width direction. The lower panel upper surface portion 40 is wide in the longitudinal direction of the vehicle body so as to sufficiently support the windshield 25 at any part from the left end 41L to the right end 41R in the vehicle width direction. By making it wide, it is possible to secure a sufficient area for supporting the windshield 25 by the lower panel upper surface portion 40. As a result, the supportability of the windshield 25 by the lower panel upper surface portion 40 can be improved, and the attachment strength for attaching the windshield 25 to the lower panel upper surface portion 40 can be increased. In addition, the degree of freedom of the shape of the windshield 25 can be increased.

  As is clear from the above description, the windshield lower panel 23 is composed of two members, the lower lower panel body 30 and the upper lower panel upper surface portion 40. The lower panel body 30 is overlapped and welded to the upper edge 22a of the dashboard lower panel 22. The lower panel upper surface portion 40 is overlapped and welded to the upper edge 33 of the lower panel main body 30. For this reason, it is possible to make the shape and size of the lower panel upper surface portion 40 different from the shape and size of the lower panel main body 30. Even the windshield lower panel 23 having a complicated three-dimensional shape can be easily formed.

  For example, the curvature of the lower panel body 30 can be increased in order to increase the living space of the passenger compartment 13. Even in this case, it is possible to sufficiently support the lower end portion 25a of the windshield 25 formed with a small curvature in response to a design request of the vehicle 10 by the lower panel upper surface portion 40. Therefore, it is possible to easily achieve the conflicting problems of expanding the living space of the passenger compartment 13 and increasing the degree of freedom in designing the vehicle 10.

  As shown in FIGS. 3 to 6, the welded portion of the lower edge 32 of the lower panel body 30 to the upper edge 22 a of the dashboard lower panel 22 and the welded portion of the lower panel upper surface portion 40 to the upper edge 33 of the lower panel body 30 are, for example, It is a joint structure by spot welding or fillet welding in a row at a predetermined pitch in the vehicle width direction. In this way, an assumed line when a plurality of welds approximately aligned in the vehicle width direction are expressed as one line is referred to as a “weld line”.

  A welding line 51 for welding the lower panel upper surface portion 40 in the vehicle width direction to the upper edge 33 of the lower panel body 30 is referred to as a “first welding line 51”. Since the lower end portion 25a of the windshield 25 having a small curvature is supported by the lower panel upper surface portion 40, the first weld line 51 has a curved shape with a small curvature in order to increase the support rigidity of the lower panel upper surface portion 40.

  A weld line 52 that welds the lower edge 32 of the lower panel body 30 to the upper edge 22a of the dashboard lower panel 22 in the vehicle width direction is referred to as a “second weld line 52”. Since the curvature of each of the dashboard lower panel 22 and the lower panel main body 30 is large, the second weld line 52 for welding these members 22 and 30 to each other has a curved shape with a large curvature. The second weld line 52 includes welding of all three members of the upper edge 22a of the dashboard lower panel 22, the rear end portion of the dashboard upper panel 24, and the lower edge 32 of the lower panel body 30.

  Further, as shown in FIG. 6, the first welding line 51 is located in front of the vehicle body with respect to the second welding line 52 in the vehicle width center portion of the lower panel upper surface portion 40. Further, the first welding line 51 is located behind the second welding line 52 in the vehicle width direction both ends 41 </ b> L and 41 </ b> R of the lower panel upper surface part 40. That is, when the vehicle body 11 is viewed from above, the first welding line 51 and the second welding line 52 intersect each other at the left and right intersections PL and PR.

  In an area AN (inner area AN) on the inner side in the vehicle width direction with respect to the left and right intersections PL and PR, the first welding line 51 is positioned in front of the vehicle body with respect to the second welding line 52. In the left and right areas AL and AR (outer areas AL and AR) on the outer side in the vehicle width direction with respect to the left and right intersections PL and PR, the first welding line 51 is located behind the second welding line 52 from the vehicle body. The outer areas AL and AR are portions of the lower panel upper surface portion 40 near the vehicle width direction both end portions 41L and 41R.

  In this way, the first weld line 51 and the second weld line 52 intersect each other. For this reason, even if the overall shape of the windshield lower panel 23 is a complicated three-dimensional shape, the upper and lower weld lines 51 and 52 intersect in plan view, so that the rigidity of the entire windshield lower panel 23 ( In particular, the bending rigidity can be sufficiently increased.

  As shown in FIGS. 2 to 4, the vertical wall 31 of the lower panel body 30 is formed with a bead 34 extending in the vehicle width direction in the vicinity of the first weld line 51. Therefore, the lower panel main body 30 can be deformed in the vertical direction with the bead 34 as a base point, even though the entire windshield lower panel 23 is highly rigid. For example, as shown by a white arrow fc in FIG. 3, when an impact object collides with the windshield 25 or the lower panel upper surface portion 40 from the outside of the vehicle, the lower panel body 30 effectively plastically deforms with the bead 34 as a base point. As a result, it is possible to obtain the characteristic of relaxing the collision energy.

  Further, the bead 34 is located in the vehicle width center portion in the lower panel main body 30. The node of the amplitude of the windshield 25 due to running vibration is approximately at the center of the vehicle width. The lower panel body 30 can easily absorb the collision energy while suppressing vibration by the portion of the bead 34 located in the vehicle width center portion.

  As shown in FIG. 1, FIG. 7 and FIG. 8, the vehicle width direction both end portions 35L, 35R of the lower panel body 30 and the vehicle width direction both end portions 41L, 41R of the lower panel upper surface portion 40 It is joined to 21R directly or indirectly by welding or the like. Specifically, both end portions 35L, 35R in the vehicle width direction of the lower panel body 30 are joined to the inner surfaces of the left and right stays 61L, 61R. The upper and lower flanges 61L, 62R of the left and right stays 61L, 61R are overlapped and joined to both ends 41L, 41R in the vehicle width direction of the lower panel upper surface portion 40 in the vertical direction. The outer surfaces of the left and right stays 61L and 61R in the vehicle width direction are joined to the left and right front pillars 21L and 21R together with the left and right pillar stiffeners 63 (only the left is shown).

  In both end portions 41L and 41R of the lower panel upper surface portion 40, the width Wi in the vehicle body front-rear direction is wide. It is possible to sufficiently secure a joining length for joining the both end portions 41L and 41R to the left and right front pillars 21L and 21R by welding or the like. Bonding strength for bonding the both end portions 41L and 41R to the left and right front pillars 21L and 21R is increased. As a result, the rigidity of the entire windshield lower panel 23 can be efficiently ensured.

  FIG. 9A shows a left cross-sectional configuration around the windshield lower panel 23 taken along the line 9a-9a in FIG. FIG. 9B shows a right cross-sectional configuration around the windshield lower panel 23 taken along the line 9b-9b in FIG. In FIG. 2, the position of the 9a-9a line and the position of the 9b-9b line are in a symmetrical position with respect to the vehicle width center line CL.

  As shown in FIG. 2, FIG. 5, and FIG. 9A, the vertical wall 31 of the lower panel body 30 is formed with an opening 36 through which the air conditioning apparatus intake duct 71 passes. The air-conditioner intake duct 71 is a part of an intake line that introduces outside air into the air-conditioner (not shown) through the cowl box 26. The opening 36 is coupled to the penetrating intake duct 71. For this reason, the periphery of the opening 36 of the vertical wall 31 is reinforced by the intake duct 71. Since the rigidity around the edge can be ensured, the shape of the opening 36 of the vertical wall 31 can be sufficiently retained.

  The opening end 72 of the intake duct 71 is located in front of the vehicle body with respect to the vertical wall 31 and the front end 42 of the lower panel upper surface portion 40. Since the opening end 72 of the intake duct 71 is located in front of the vehicle body with respect to the vertical wall 31 of the lower panel body 30, the intake portion 73 of the intake duct 71 can be shifted to the front of the vehicle body. When the intake portion 73 is displaced forward of the vehicle body, the intake duct 71 can be disposed while ensuring the living space of the passenger compartment 13.

  As described above, the opening end 72 of the intake duct 71 is positioned in front of the vehicle body with respect to the front end 42 of the lower panel upper surface portion 40. That is, the position of the front end 42 of the lower panel upper surface portion 40 may be a position where the lower end portion 25a of the windshield 25 can be supported without extending more forward than necessary. The width Wi of the lower panel upper surface portion 40 in the longitudinal direction of the vehicle body can be easily set to a minimum size capable of supporting the lower end portion 25a of the windshield 25.

  The vertical wall 31 of the lower panel body 30 is formed substantially symmetrically with respect to the vehicle width center line CL. However, the portion of the vertical wall 31 in which the opening 36 is formed as shown in FIG. 9A protrudes forward of the vehicle body relative to the other portion (see FIG. 9B). Only Di is protruding. Although configured in this manner, the lower panel upper surface portion 40 is formed of a separate member with respect to the lower panel main body 30, so that the left and right symmetrical windshield 25 can be reliably supported by the windshield lower panel 23.

  The vehicle body front part structure of the present invention is suitable for use in passenger cars.
