Description

Technical Field

[0001] This invention relates to the front structure of a vehicle body. Background Technology

[0002] In recent years, we have been actively promoting the inclusion of traffic participants, especially vulnerable groups such as the elderly and children, in sustainable transportation systems. With this goal in mind, we are committed to research and development aimed at further improving traffic safety and convenience through advancements related to vehicle collision safety performance.

[0003] Conventionally, front body structures with grille support members are known, wherein the grille support member supports the rear side of a front grille disposed at the front of the body at its central portion in the vehicle width direction (see, for example, Patent Document 1). Specifically, the grille support member fixes its rear end to the lower end of a central support, which extends between a frame-shaped shroud disposed in front of the radiator and a bumper crossbeam. Furthermore, the grille support member supports the central portion of the front grille in the vehicle width direction from its front end, which extends diagonally forward and upward from its fixing portion to the central support.

[0004] According to the front body structure with such a grille support member, the grille support member can be used to prevent the central part of the front grille in the vehicle width direction from deflecting downward due to the weight of the front grille itself.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2007-216927 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] However, in existing vehicle front structure (see, for example, Patent Document 1), if the front of the vehicle collides with a pedestrian, the collision load is mostly transferred from the front grille to the rear and downward.

[0010] However, as mentioned earlier, the grille support components in existing front-end vehicle structures are configured to provide support against collision loads between the front grille and the lower end of the central support connected to the bumper crossbeam. Therefore, existing front-end vehicle structures may not be efficient at absorbing the loads input during a pedestrian collision.

[0011] Furthermore, in existing vehicle front structures (see, for example, Patent Document 1), the front grille is supported by a grille support member that slopes downwards and backwards, which can cause it to bend backwards due to wind pressure during vehicle movement. Therefore, if a radar for sensing obstacles is installed in the front grille, the existing vehicle front structure has the problem of making it difficult to ensure radar performance due to the deflection of the front grille caused by wind pressure.

[0012] Therefore, the objective of this invention is to provide a front body structure that improves pedestrian collision safety and, compared to previous methods, suppresses front grille deformation caused by wind pressure during vehicle movement. Furthermore, it contributes to the development of sustainable transportation systems.

[0013] Methods for solving problems

[0014] The present invention, which solves the aforementioned problems, is characterized by having: a front bumper having an opening; a front grille mounted on the front bumper; an air guide member disposed behind the opening of the front bumper, which guides external air taken in from the opening rearward; a radar mounted on the front grille; and a grille support member disposed behind the radar, extending substantially horizontally in the longitudinal direction of the vehicle, the front end of the grille support member being directly or indirectly fixed to the front grille via the radar, and the rear end of the grille support member being fixed to the air guide member.

[0015] Invention Effects

[0016] According to the present invention, a front body structure is provided that can improve pedestrian collision safety performance and suppress deformation of the front grille caused by wind pressure or temperature changes of external gases during vehicle operation compared to the past.

Furthermore, in the following description, the left-right direction of the vehicle body may be referred to as the vehicle width direction.

[0038] The following will first describe the body with this front structure, and then describe the front structure of the body in detail.

[0039] The Composition of the Car Body

[0040] Figure 1 This is a partially enlarged perspective view of a vehicle body 10 having the front structure of this embodiment. Figure 1 The image shows the engine hood and headlights being removed from the vehicle body 10.

[0041] like Figure 1 As shown, in this embodiment, the front of the vehicle body 10 is provided with a power equipment compartment R for accommodating a drive electric motor, internal combustion engine, etc. (not shown). The power equipment compartment R is covered from above by an engine hood (not shown) that can be opened and closed.

[0042] At the front of the vehicle body 10, the front bumper (front bumper exterior part) 2 extends to the left and right. The front bumper 2 has an upper opening 11 and a lower opening 12.

[0043] It should be noted that the upper opening 11 in the upper opening 11 and the lower opening 12 is equivalent to the "opening of the front bumper" in the claims.

[0044] In this embodiment, the upper opening 11 is formed by cutting a notch in the center of the front bumper 2 in the vehicle width direction when viewed from the front of the vehicle.

[0045] A mesh upper front grille 5 is installed in such an upper opening 11. This upper front grille 5 is equivalent to the "front grille" in the claims.

[0046] In this embodiment, the upper front grille 5 is honeycomb-shaped. Furthermore, a logo mounting portion 32 for mounting a logo (not shown) is formed at the center of the upper front grille 5 in the vehicle width direction. Additionally, a frame-shaped radar housing portion 34 is formed at the center of this logo mounting portion 32. The radar 8 described later (see...) Figure 2 The radar 8 is positioned on the rear side of the upper front grille 5 within the radar housing 34. Thus, the radar 8 is located immediately behind the vehicle emblem (not shown).

[0047] It should be noted that the upper portion of the front upper grille 5 extends upward compared to the upper opening 11. Furthermore, headlights (not shown) are positioned on the outer side of the upper portion of this extended front upper grille 5 in the vehicle width direction.

[0048] The lower opening 12 is formed on the front bumper 2 in a manner located below the bumper crossbeam (not shown).

[0049] In this embodiment, the lower opening 12 is a long and narrow rectangle when viewed from the front of the vehicle. A front door grille 7 made of a honeycomb mesh is installed in this lower opening 12.

[0050] It should be noted that, in Figure 1 In the accompanying drawing, reference numeral 9 indicates a cover component that extends laterally in the vehicle width direction. This cover component 9 is disposed on the grille baffle 6, which is described later (see Figure 6). Figure 2 ) Frame component 6a (see Figure 2 The upper part of the component and the leading edge of the opening of the power equipment room R are covered to cover the air guide component 4 (see below). Figure 2 Above )

[0051] Figure 2 This shows the cover component 9 (see Figure 1 Remove the radar 8, leaving it on the side of the vehicle body 10, and remove the upper front grille 5 (see...). Figure 1 A magnified 3D view of the front of the vehicle body after it has been removed. Figure 3 It shows that Figure 1 The cover component 9 shown can be removed from... Figure 1 A magnified three-dimensional view showing the rear side of the upper front grille 5, viewed in the direction of arrow III.

[0052] like Figure 2 As shown, the vehicle body 10, starting from the front side, is equipped with the upper front grille 5 (see...). Figure 1 The radar 8, grille support component 3, air guide component 4, and grille baffle 6 are included. Additionally, although not shown in the diagram, a front partition and an assembly comprising a cooling device including a radiator are disposed behind the grille baffle 6.

[0053] For ease of drawing, Figure 2 The radar 8 shown is paired with the upper front grille 5 (see...). Figure 1 Separate drawing, but actually configured in Figure 1 The radar housing 34 is shown in the diagram. The radar 8 is configured as having a sensor unit 8a that senses obstacles in front of the vehicle.

[0054] Although the illustration is omitted, the sensor unit 8a includes: radar main body 8a1 (see...) Figure 6 Its configuration includes housing high-frequency circuitry, antennas, etc., within a housing; and a connector connection portion 8a2 (see...). Figure 6 ), which supplies the harness H (see below) consisting of power lines, signal lines, etc. Figure 6 )connect.

[0055] In addition, Radar 8, such as Figure 3 As shown, it has a sensor section 8a (see...) Figure 2 The grid-like support disk 8b on the rear surface of the )

[0056] Sensor section 8a (see Figure 2 The support plate 8b is fixed to the rear surface of the front upper grille 5 by bolts or other fasteners.

[0057] in addition, Figure 3 The grille support component 3 shown is the component that connects the rear surface of the upper front grille 5 to the air guide component 4. Details of the grille support component 3 and the air guide component 4 will be provided later.

[0058] like Figure 2 As shown, the grille baffle 6 is positioned on the front upper grille 5 (see...). Figure 1 The upper opening 11 is installed behind and in front of the radiator (not shown). In this embodiment, the grille baffle 6 is envisioned to have a frame member 6a fixed to the front partition (not shown) (see...). Figure 2) and a baffle body (not shown) supported by the frame component 6a. The grille baffle 6 is controlled to, at a predetermined timing as needed, direct air from the front upper grille 5 (see [reference]) via a pipe-like air guide component 4. Figure 1 The upper opening 11 of the radiator can guide the airflow to the rearward side of the radiator for supply or block it.

[0059] Front Structure of the Vehicle Body

[0060] Next, the front structure of the vehicle body in this embodiment will be described.

[0061] like Figure 2 As shown, the front structure 1 of the vehicle body in this embodiment is configured to mainly include a grille support member 3 disposed behind the radar 8 and an air guide member 4 for fixing the rear end of the grille support member 3.

[0062] Figure 4 This is a three-dimensional view of the air guiding component 4. It should be noted that... Figure 4 In the diagram, the grille support member 3 installed on the air guide member 4 is indicated by an imaginary line (dashed line).

[0063] First, let's explain the air guiding component 4.

[0064] like Figure 4 As shown, the air guiding component 4 is in the shape of a pipe made of a rectangular cylindrical body.

[0065] Specifically, the air guiding component 4 includes an upper rectifier 25, a lower rectifier 26, and a pair of side plates 27, 27 connecting the two end edges of the upper rectifier 25 and the lower rectifier 26 in the vehicle width direction.

[0066] The rear opening and structure of the air guide component 4 Figure 2 The grille baffle 6 shown is configured with a corresponding front opening in the frame member 6a. Furthermore, the air guide member 4 is connected to the frame member 6a (see [reference]) by means of mounting ribs 28 formed on both sides in the vehicle width direction and extending vertically. Figure 2 )connect.

[0067] Additionally, although the illustration is omitted, the air guide component 4 supports the leading edge of the lower fairing 26 on the upper surface of the bumper beam.

[0068] like Figure 3 As shown, the upper fairing 25 of the air guiding component 4 has a mounting portion 29 for the grille support component 3 at its leading edge extending forward from the grille baffle 6 side. Incidentally, in this embodiment, the mounting portion 29 for the grille support component 3 is a portion partially recessed at the center of the leading edge of the upper fairing 25 in the vehicle width direction. It should be noted that... Figure 3In the figure, reference numeral P is a connecting pin for mounting the grille support component 3, which will be described later.

[0069] And, as Figure 4 As shown, in the mounting portion 29 of the grille support member 3, there is a connecting pin P (see...) Figure 3 A through hole 31 is formed at the corresponding position.

[0070] The air guiding component 4 of this embodiment is envisioned to be constructed from an elastomer such as flexible resin or synthetic rubber. Among these, an air guiding component 4 made of resin is particularly preferred.

[0071] Next, the grid support component 3 will be described.

[0072] Figure 5A This is a perspective view of the grille support component 3 from the upper left front. Figure 5B This is a three-dimensional view of the grille support component 3 from a top-left rear view. Figure 5C yes Figure 5A Vc-Vc sectional view.

[0073] It should be noted that, Figures 5A to 5C The front-back, up-down, left-right directions of the grille support component 3 shown are... Figures 2 to 4 The directions in the middle are consistent: front, back, up, down, left, and right.

[0074] like Figure 5A and Figure 5B As shown, the grille support member 3 has an approximate H-shape when viewed from above. That is, the grille support member 3 has a pair of horizontal portions 16 and a connecting portion 17 that connects these horizontal portions 16 to each other.

[0075] Specifically, the horizontal sections 16 are positioned relative to each other in the vehicle width direction (see...). Figure 5A The horizontal sections 16 are arranged at prescribed intervals in the left-right direction and extend roughly horizontally in the front-back direction. These horizontal sections 16 are symmetrical to each other.

[0076] exist Figure 5A As shown by the dashed line, the connecting part 17 is formed of a plate with an L-shaped cross-section. The connecting part 17 connects the horizontal parts 16 to each other at a position that is moved rearward compared to the central part in the front-rear direction of the horizontal parts 16.

[0077] like Figure 5C As shown, the horizontal portion 16 includes a horizontal portion body 22 having a downwardly opening U-shaped cross-section and an inner edge portion 23 having an L-shaped cross-section extending from the horizontal portion body 22.

[0078] Inner edge 23 Figure 5AAs shown, it bends into an L-shape with its top end extending downwards from the lower edge of the horizontal main body 22 toward the adjacent horizontal part 16. Furthermore, as... Figure 5A As shown, the rear end of the inner edge 23 extending along the horizontal body 22 is integrated with the connecting part 17 of the L-shaped cross section.

[0079] like Figure 5A As shown, the front end of the horizontal main body 22 with a U-shaped cross-section is located in the vehicle width direction ( Figure 5A The plate-shaped front face 19 extends in both the left-right direction and the up-down direction and is closed.

[0080] In addition, such as Figure 5A and Figure 5B As shown, the rear end of the horizontal main body 22 is closed by the rear face 21. The rear face 21 is formed by an inclined plate that gradually shifts downward as it tends to move downward.

[0081] like Figure 5A and Figure 5B As shown, an upper extension portion 13 is provided at the front of the horizontal portion 16.

[0082] The upper extension portion 13 is formed by a plate that rises upward from the upper surface of the horizontal portion 16, slightly rearward than the front portion 19. This upper extension portion 13 is as follows... Figure 5A As shown, it is formed within the range from the horizontal main body 22 to the inner edge 23.

[0083] like Figure 5B As shown, a screw insertion hole 14 is formed in the upper extending portion 13. Furthermore, as... Figure 5A As shown, a column ring portion 15 is formed on the front of the upper extension portion 13 at a position corresponding to the screw insertion hole 14. As described later, the front upper grille 5 (see [reference]) is embedded in this column ring portion 15. Figure 6 The boss portion 33 formed on the surface (see) Figure 6 ).

[0084] In addition, such as Figure 5A and Figure 5B As shown, a reinforcing rib 24 extending upward from the horizontal portion 16 is formed at the front of the horizontal portion 16.

[0085] The reinforcing rib 24 Figure 5B As shown, it is formed of a right-angled triangular plate. Furthermore, the reinforcing rib 24 is disposed at the corner formed by the rear surface of the upper extension portion 13 and the upper surface of the horizontal main body 22, and is integrally formed with the upper extension portion 13 and the horizontal main body 22.

[0086] In addition, such as Figure 5A and Figure 5B As shown, a connecting pin P is formed at the rear of the horizontal main body 22 (see Figure 1). Figure 3 ) The engaging hole 22a.

[0087] Next, the support structure of the front upper grille 5 formed by the grille support member 3 will be described.

[0088] like Figure 3 As shown, the upper extension portion 13 of a pair of horizontal portions 16 in the grille support member 3 is fixed to the front upper grille 5 near the left and right sides of the radar 8.

[0089] Specifically, such as as Figure 3 VI-VI sectional view Figure 6 As shown, a boss 33 formed on the front upper grille 5 is embedded inside the pillar ring portion 15 provided on the upper extension portion 13.

[0090] The boss portion 33 has a threaded portion (not shown) that engages with a screw hole 14 in the upper extending portion 13 (see...). Figure 5B The screw S in the upper extension part 13 is thus fixed by abutting against the front upper grille 5 from the rear.

[0091] Furthermore, the upper extension setting part 13 is threaded to the boss part 33, so that the front part 19 in the horizontal part 16 abuts against the rear surface of the front upper grille 5.

[0092] like Figure 3 As shown, the grille support member 3, which is installed on the rear surface of the front upper grille 5, is configured such that the portion located behind the radar 8 is recessed rearward between a pair of horizontal portions 16 to form a recess 18.

[0093] Incidentally, the radar 8 in this embodiment is as follows: Figure 6 As shown, a connector connection portion 8a2 protrudes downward from the radar body portion 8a1. Furthermore, a wire harness H extending from above passes through a recess 18 (see...). Figure 3 It was then pulled back and connected to the connector connection part 8a2.

[0094] Furthermore, in Figure 3 In the middle, the rear end of the grille support component 3, indicated by the hidden line (dashed line), is fixed to the upper rectifier plate 25 of the air guide component 4 by the connecting pin P.

[0095] Specifically, such as Figure 6 As shown, the rear end of the horizontal portion 16 in the grille support member 3 is arranged in an overlapping manner with the upper rectifier plate 25 of the air guide member 4 on its lower side.

[0096] Furthermore, the engaging pin P, which is inserted into the through hole 31 of the upper rectifier plate 25, engages with the engaging hole 22a of the horizontal part 16, thereby fixing the rear end of the grille support member 3 to the upper rectifier plate 25 of the air guide member 4.

[0097] Incidentally, the connecting pin P in this embodiment is envisioned as a spring-loaded locking pin, but it can also be replaced by other fasteners such as rivets, bolts, and screws.

[0098] The horizontal portion 16 of the grille support member 3, which connects the upper front grille 5 to the air guide member 4, extends from the portion fixed to the upper front grille 5 to the portion fixed to the air guide member 4. Figure 5C The cross-section shown is shaped like the character "コ".

[0099] Effects and Functions

[0100] The following describes the effects of the front body structure 1 of this embodiment.

[0101] Typically, the front grille located at the front of a vehicle body tends to warp due to rearward compression from the driving wind or thermal expansion caused by temperature changes in the external air. Therefore, in a front-end vehicle structure where radar is installed in the front grille, there is a possibility that the radar cannot accurately detect obstacles in front of the vehicle due to the warping of the front grille.

[0102] In this embodiment, the front end of the grille support member 3, which extends substantially horizontally in the longitudinal direction of the vehicle, is fixed to the upper front grille 5 (front grille). Furthermore, the rear end of the grille support member 3 is fixed to the air guide member 4.

[0103] According to this front body structure 1, the upper front grille 5 is supported from the rear by the grille support member 3 to provide support against rearward deflection caused by changes in the temperature of the driving wind or external gases. As a result, the front body structure 1 can suppress the deflection of the upper front grille 5 caused by changes in wind pressure or external gas temperature, enabling accurate sensing by the radar 8.

[0104] In addition, in the front structure 1 of the vehicle body, the rear end of the grille support member 3 is fixed to the air guide member 4 made of resin.

[0105] Based on this front body structure 1, for minor collisions and pedestrian collisions, which have a higher wind pressure than during driving, the air guiding component 4 deforms, resulting in excellent collision load absorption performance.

[0106] That is, with such a front body structure 1, it is possible to improve the collision safety performance against pedestrians and suppress the deformation of the upper front grille 5 caused by wind pressure or temperature changes of external gases during vehicle operation compared to the past.

[0107] In addition, in the front structure 1 of the vehicle body, the upper extension 13 of the grille support member 3 abuts against and is fixed to the upper front grille 5 (front grille) from the rear.

[0108] According to this front body structure 1, the upper front grille 5, which may be bent rearward due to temperature changes from the driving wind or external air, can be firmly supported from the rear by the grille support member 3.

[0109] In addition, in the front structure 1 of the vehicle body, the rear end of the grille support member 3 and the air guide member 4 overlap and are fixed to each other in the vertical direction.

[0110] According to this front body structure 1, when a load greater than the wind pressure during driving, caused by a minor collision or a collision with a pedestrian, is input from the front, a shear force acts between the grille support member 3 and the air guide member 4. Furthermore, this shear force deforms the connecting pin P, the through hole 31, the engaging hole 22a, etc., which constitute the fixing part of the grille support member 3 and the air guide member 4. According to this front body structure 1, the grille support member 3 fails to provide support for the input collision load, and the fixing part deforms. Therefore, the front body structure 1 exhibits excellent collision load absorption performance.

[0111] In addition, in the front structure 1 of the vehicle body, the grille support component 3 is fixed to the upper front grille 5 (front grille) near the left and right sides of the radar 8.

[0112] Based on this front body structure 1, the deflection of the long upper front grille 5 caused by temperature changes in the driving wind or external gas can be effectively suppressed.

[0113] In addition, in the front structure 1 of the vehicle body, the grille support member 3 is formed in a way that the part located behind the radar 8 is recessed to the rear.

[0114] Based on this front body structure 1, the grille support component 3 will not obstruct the wiring of the H-direction radar 8.

[0115] In addition, in the front structure 1 of the vehicle body, the grille support member 3 has a reinforcing rib at the corner formed by the horizontal part 16 and the upper extended part 13.

[0116] Based on this front body structure 1, the upper extension portion 13 is prevented from deforming due to temperature changes in the driving wind or external gas by the reinforcing ribs 24, thereby more effectively suppressing the deflection of the upper front grille 5.

[0117] Furthermore, in the front structure 1 of the vehicle body, the horizontal portion 16 of the grille support member 3 is formed by a downwardly opening U-shaped cross section, from the fixing part with the upper front grille 5 (front grille) to the fixing part with the air guide member 4.

[0118] Based on this front body structure 1, the horizontal part 16 has high rigidity in the longitudinal direction, which can more effectively suppress the deflection of the upper front grille 5 caused by temperature changes in the driving wind or external gas.

[0119] Furthermore, in the front structure 1 of the vehicle body, the horizontal portion 16 of the grille support member 3 has a front portion 19 with a U-shaped cross section. The front portion 19 abuts against the upper front grille 5 (front grille).

[0120] According to this front body structure 1, since the grille support member 3 more firmly supports the front upper grille 5 from the rear, the deflection of the front upper grille 5 caused by temperature changes of driving wind or external gas can be further effectively suppressed.

[0121] The above description of this embodiment is not limited to the aforementioned embodiment and can be implemented in various ways.

[0122] In the aforementioned embodiment, the grille support member 3 fixes the front end of the horizontal portion 16 to the front upper grille 5 on the outer side of the radar 8 in the vehicle width direction. However, the grille support member 3 is not limited to having the horizontal portion 16 directly fixed to the front upper grille 5 as shown in this way; it can also be configured such that the horizontal portion 16 is fixed to the radar 8 (support plate 8b) and indirectly supports the front upper grille 5.
