Description

[Technical field]

[0001] The present invention relates to a console box for a vehicle. [Background technology]

[0002] Various techniques have been proposed for vehicle console boxes that are installed between the driver's seat and the passenger seat in the passenger compartment of a vehicle (mainly an automobile). For example, the rear console described in Patent Document 1 below houses a plastic box that opens upward and stores small items. The bottom wall and side wall of the box are covered from the outside by a plastic surface panel. The opening of the box is opened and closed by a plastic lid that is provided so as to be rotatable via a hinge.

[0003] The bottom wall of the box is provided with a contact portion that protrudes downward and contacts a bracket on the vehicle body side and is bolted to the bracket, and a weak portion that is located on the vehicle body rear side of the contact portion and is composed of multiple notched grooves. When sudden braking is applied and the head of a rear seat passenger hits the rear portion of the lid from above, the impact load is transmitted from the hinge portion through the side wall of the box to the weak portion formed in the bottom wall, causing the weak portion to break, thereby absorbing and mitigating the impact load. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-30555 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the rear console described in Patent Document 1, although a weak portion is formed in the bottom wall of the box to absorb and mitigate the impact load, there is a risk that the mechanical rigidity during actual use will decrease, resulting in a deterioration in marketability. Also, when an impact load acts on the rear part of the lid from above, it is assumed that the impact load will not be transmitted properly to the side wall and bottom wall, and there is a risk that the impact load will not be efficiently absorbed and mitigated.

[0006] Therefore, the present invention has been devised in consideration of these points, and its object is to provide a console box for a vehicle that ensures mechanical rigidity during actual use while efficiently absorbing and mitigating impact loads. [Means for solving the problem]

[0007] In order to solve the above problems, a first aspect of the present invention is a console box for a vehicle, comprising a box body that opens upward and stores items, and a console lid that is provided so as to be able to open and close relative to the upper opening of the box body, wherein the console lid is formed into an inner and outer double structure by an outer member and an inner member, and the outer member has a lower surface that faces the inner member, a lower surface rib portion that protrudes in a rib shape along the vehicle width direction toward the inner member, and is provided so that both vehicle width direction ends face both side edges of the inner member in the vehicle width direction, and a predetermined A vehicle console box having a pair of rib protrusions protruding in a rib-like shape to a predetermined height toward the inner member from each lower end of the inner member extending along the length of the vehicle width direction, the inner member having a pair of weak parts provided at positions opposite each of the pair of rib protrusions on its upper surface facing the outer member and breakable by an impact load acting from above the outer member, and when an impact load acts from above the outer member, the impact load is transmitted to the opposing weak part via one of the pair of rib protrusions, causing the weak part to break.

[0008] Next, the second invention of the present invention is a vehicle console box according to the first invention above, wherein the inner member has a lower core member that constitutes the bottom portion of the console lid, and an upper core member in a plate shape formed in a rectangular shape in a plan view, arranged to cover the lower core member and facing the underside of the outer member, and a pair of the weak portions are provided at positions facing each of a pair of rib protrusions of the upper core member.

[0009] Next, a third aspect of the present invention is a vehicle console box according to the second aspect of the present invention, wherein the core upper member has a pair of vertical wall portions extending downward a predetermined length from both side edges in the vehicle width direction over the entire length thereof, and a pair of flange portions extending outward in the vehicle width direction from the pair of vertical wall portions, and each of the pair of weak portions has a first notch groove portion extending in the vehicle width direction from the outer side edges in the vehicle width direction to a predetermined length inward in the vehicle width direction from a position facing an inner end of the opposing rib convex portion, facing a lower surface of the rib convex portion, and a second notch groove portion extending from an inner end portion of the first notch groove portion along the vertical wall portion toward an area with higher rigidity in the vehicle fore-and-aft direction, and a third notch groove portion extending a predetermined length diagonally inward in the vehicle width direction from an inner end portion of the first notch groove portion toward an area with higher rigidity in the vehicle fore-and-aft direction, and then extending further along the outer side edge of the core upper member in the vehicle width direction toward an area with higher rigidity in the vehicle fore-and-aft direction, wherein the first notch groove portion to the third notch groove portion are arranged in a U-shape in plan view opening toward the area with higher rigidity in the vehicle fore-and-aft direction.

[0010] Next, a fourth invention of the present invention is a console box for a vehicle relating to the third invention above, wherein each of the pair of weak portions has a fourth notch groove portion extending along the vehicle width direction from the vehicle width outer end of the first notch groove portion to a position opposite the vehicle width outer end of the opposing rib convex portion of the vertical wall portion and the flange portion, facing the underside of the rib convex portion.

[0011] Next, the fifth invention of the present invention is a console box for a vehicle relating to the third or fourth invention above, wherein the first notch groove portion has a slit portion formed along the vehicle width direction so as to include a position opposite to the vehicle width direction inner end portion of the opposing rib convex portion, and the slit portion penetrates with the width of the upper end portion of the first notch groove portion.

[0012] Next, a sixth invention of the present invention is a vehicle console box relating to any one of the third to fifth inventions above, wherein the core upper member has a step portion provided across the entire width of the vehicle in the vehicle width direction, forward of the first notch groove portion of each of a pair of weak portions in the vehicle fore-and-aft direction, and the second notch groove portion and the third notch groove portion extend from both vehicle width direction ends of the first notch groove portion to the step portion. Effect of the Invention

[0013] According to the first aspect of the present invention, when a static load acts on the outer member of the console lid under normal conditions, the static load is transmitted to the box body, etc., via the outer member and the inner member. As a result, the mechanical rigidity of the vehicle console box during actual use can be ensured under normal conditions. Also, when an impact load acts on the outer member of the console lid from above, the impact load is transmitted to the opposing weak parts via one of a pair of rib protrusions provided on the underside of the outer member. Then, by breaking the weak parts, the impact load acting on the outer member can be efficiently absorbed and mitigated.

[0014] According to the second aspect of the present invention, the pair of weak portions are provided at positions facing the pair of rib protrusions of the upper core member disposed facing the lower surface of the outer member, and as a result, the upper core member having the pair of weak portions is covered by the outer member and the lower core member constituting the bottom surface of the console lid, thereby improving the appearance of the console lid.

[0015] According to the third aspect of the present invention, when an impact load acts from above on the outer member, the impact load acts on the first notch groove of the opposing weak portion through one of the pair of rib protrusions, and the first notch groove is broken by the impact load. The impact load is then transmitted to the second and third notch grooves connected to both ends of the first notch groove in the vehicle width direction and extending toward the side with higher rigidity, causing the second and third notch grooves to break, and the impact load is absorbed and mitigated. Therefore, the impact load acting on the outer member of the console lid can be efficiently absorbed and mitigated.

[0016] According to the fourth aspect of the present invention, a fourth notch groove is provided extending along the vehicle width direction from the vehicle width outer end of the first notch groove to a position facing the vehicle width outer end of the opposing rib convex portion of the vertical wall portion and the flange portion, facing the lower surface of the rib convex portion. When an impact load acts from above the outer member, the impact load is transmitted to the fourth notch groove extending along the vehicle width direction from the vehicle width outer end of the first notch groove, and the fourth notch groove is broken, so that the impact load is absorbed and mitigated. Therefore, the impact load acting on the outer member of the console lid can be reliably absorbed and mitigated.

[0017] According to the fifth aspect of the invention, when an impact load acts from above the outer member, the vehicle width direction inner end of the rib convex portion enters the slit portion, and the first notch groove portion can be reliably broken from both ends of the slit portion in the vehicle width direction. As a result, the impact load is transmitted to the second notch groove portion and the third notch groove portion that are connected to both ends of the first notch groove portion in the vehicle width direction and extend toward the side with higher rigidity, and the second notch groove portion and the third notch groove portion are broken, and the impact load is absorbed and mitigated. Furthermore, the impact load is also transmitted to the fourth notch groove portion, and the fourth notch groove portion is broken, and the impact load is absorbed and mitigated. Therefore, the impact load acting on the outer member of the console lid can be more reliably absorbed and mitigated.

[0018] According to the sixth aspect of the present invention, the step portion provided across the entire width in the vehicle width direction of the core upper member increases the rigidity of the vehicle front-rear direction front side compared to the first notch groove portion of each of the pair of weak portions. Therefore, the second notch groove portion and the third notch groove portion extend from both ends in the vehicle width direction of the first notch groove portion to the step portion, that is, toward the vehicle front-rear direction front side. As a result, when an impact load acts from above on the vehicle front-rear direction rear side of the console lid, the impact load can be transmitted to the second notch groove portion and the third notch groove portion formed in the impact load direction, causing the console lid to break. Therefore, the impact load acting from above on the vehicle front-rear direction rear side of the outer member of the console lid can be reliably absorbed and mitigated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] A detailed description will be given below with reference to the drawings based on one embodiment of a console box for a vehicle according to the present invention. First, a schematic configuration of a console box for a vehicle 1 will be described based on Fig. 1 to Fig. 3. Note that "front" and "rear" appropriately indicated by solid arrows in each drawing indicate the front and rear directions in the vehicle longitudinal direction, and "right" and "left" indicate the right and left directions in the vehicle width direction relative to the front side of the vehicle. "Top" and "bottom" indicate the top and bottom directions in the vehicle vertical direction.

[0021] 1 to 3, a vehicle console box 1 disposed between a driver's seat and a passenger seat disposed in a passenger compartment of a vehicle (mainly an automobile) includes a console body 3, a box body 5, and a console lid 7. The console body 3 is formed of a synthetic resin material, and includes a design panel 12 on which left and right cup holders 11, a shift lever (not shown), a handbrake (not shown), and the like are disposed, left and right side panels 13 (the left side panel 13 is shown in Figs. 1 and 2), and an end panel 15. The end panel 15 is attached to the rear edges of the left and right side panels 13, and connects the rear edges of the left and right side panels 13 together.

[0022] 2 and 3, the box body 5 stored in the console main body 3 is formed in a generally box shape with front, rear, left and right upright wall portions 18 and a bottom plate portion 19 that form an item storage chamber 17 that opens upward and stores items. The box body 5 has a lower outer surface of one of the upright wall portions 18 fastened and fixed by a fastening member such as a bolt to a fixing bracket (not shown) disposed on the floor panel of the vehicle compartment.

[0023] The console lid 7, which covers the upper opening 21 that opens upward on the box body 5, is provided with left and right arms 23 that extend downward in an arc shape at the rear of both left and right edges of the bottom surface. A lever 25 that extends upward is formed at the tip of each arm 23. A hinge shaft 26 is inserted into the tip of each lever 25, and each arm 23 and lever 25 are supported inside the end panel 15 so as to be rotatable.

[0024] Therefore, the rear portion of the console lid 7 is attached to the console body 3 via the arms 23 and levers 25 so as to be rotatable about the hinge shaft 26. A downwardly projecting stopper portion 25A is formed on the base end side of each lever 25. As shown in Fig. 2, when the console lid 7 is rotated from the closed position to the open position, the stopper portions 25A come into contact with the inner upper end surfaces of the left and right side panels 13, and the console lid 7 is held in the open position.

[0025] Next, a schematic configuration of the console lid 7 will be described with reference to Fig. 3 to Fig. 9. As shown in Fig. 3 and Fig. 4, the console lid 7 has an inner and outer double structure made up of an outer member 28 and an inner member 29. The outer member 28 is made of a synthetic resin material and includes an upper plate portion 31 and side wall portions 32 that extend gently downward from both side edges of the upper plate portion 31 in the vehicle width direction and have a curved cross section, and is formed into a substantially rectangular shape that is elongated in the vehicle front-rear direction in plan view.

[0026] The inner member 29 is made of a synthetic resin material and is composed of left and right side wall portions 32 of the outer member 28, a substantially plate-shaped core lower member 35 that covers the lower sides of the front and rear end edges of the outer member 28, and a substantially plate-shaped core upper member 36 that is disposed between the top surface of the core lower member 35 and the bottom surface of the outer member 28. The core lower member 35 is formed with a width substantially equal to the distance between the inner wall surfaces of the left and right side wall portions 32 of the outer member 28.

[0027] The lower core member 35 covers the underside of the outer member 28 from the front end edge to a predetermined length (e.g., about 3 cm to 4 cm) rearward, and then extends downward a predetermined height (e.g., about 3 cm to 4 cm) so as to face positions near the lower ends of both side wall portions 32 of the outer member 28. The lower core member 35 further extends approximately parallel to the upper plate portion 31 of the outer member 28 to the vicinity of the rear end of the outer member 28, and then gently extends upward and is connected to the rear end edge of the outer member 28. Therefore, the lower core member 35 is formed in a substantially rectangular shape in plan view, with a width approximately equal to the distance between the inner wall surfaces of the left and right side wall portions 32 of the outer member 28 and a length approximately equal to the length of the outer member 28 in the vehicle front-rear direction.

[0028] A release lever 38 for unlocking a lock mechanism (not shown) that releasably locks the console lid 7 in a closed state is provided at the front portion of the core lower member 35 so as to be swingable in the vertical direction of the vehicle. The front end of the release lever 38 protrudes from a horizontally elongated rectangular through hole 39 formed in the front wall portion 35A of the core lower member 35. The front end of the release lever 38 is biased to rotate downward by a compression coil spring 41 that biases the rear end of the release lever 38 upward, and is held in a substantially horizontal position.

[0029] Then, by pulling the front end of the release lever 38 upward, the locking mechanism (not shown) is released, and the console lid 7 can be opened upward. Thereafter, by closing the console lid 7, the locking mechanism (not shown) is locked, and the console lid 7 is locked again in the closed state. The front end of the release lever 38 is biased by the compression coil spring 41 so as to rotate downward, and is held in a substantially horizontal position.

[0030] 3 to 5, the core upper member 36 is disposed between the release lever 38 and the inner lower surface of the outer member 28, and has an upper plate portion 43 having a generally rectangular shape in plan view, with a width in the vehicle width direction slightly narrower than the width in the vehicle width direction of the core lower member 35, covering the upper part of the release lever 38. The core upper member 36 also has a vertical wall-like stepped portion 45 extending downward for a predetermined height (for example, about 1 cm in height) from the rear end edge of the upper plate portion 43 over the entire width. The core upper member 36 also has a lower plate portion 46 having a generally rectangular shape in plan view that is long in the vehicle front-rear direction and extends rearward in the vehicle front-rear direction over the entire width from the lower end edge of the stepped portion 45.

[0031] 4 and 5, the upper core member 36 has a pair of vertical wall portions 48 extending downward over the entire length from both side edges in the vehicle width direction of the upper plate portion 43, the step portion 45, and the lower plate portion 46. The upper core member 36 also has a pair of flange portions 49 extending outward in the vehicle width direction at a substantially right angle over the entire length from the lower end edges of each of the pair of vertical wall portions 48. The pair of flange portions 49 of the upper core member 36 are formed with reinforcing ribs 51 extending downward a predetermined height (for example, about 0.5 cm to 1 cm) from the outer side edges in the vehicle width direction from a position facing the vicinity of the rear end edge of the upper plate portion 43 to a position facing the vicinity of the rear end edge of the lower plate portion 46.

[0032] 3 and 5, the upper core member 36 has a vertical wall portion 52 that extends downward over its entire width from the rear end edge of the lower plate portion 46 in the vehicle fore-and-aft direction and connects the rear end edges of the pair of vertical wall portions 48. The upper core member 36 also has a flange portion 53 that extends at a substantially right angle from the lower end edge of the vertical wall portion 52 over its entire length outward in the vehicle fore-and-aft direction and connects the rear end edges of the pair of flange portions 49.

[0033] As shown in Fig. 5, the upper plate portion 43 of the core upper member 36 is provided with low-height reinforcing ribs 55 formed in a cross shape in a plan view at both ends and approximately the center in the vehicle width direction of the front and rear end edges in the vehicle front-rear direction. Also, as shown in Figs. 3 and 5, the lower plate portion 46 of the core upper member 36 is provided with two rows of reinforcing ribs 56 extending linearly from the lower end edge of the step portion 45 to approximately the center in the vehicle front-rear direction of the lower plate portion 46, symmetrically arranged with respect to the center position in the vehicle width direction. The reinforcing ribs 56 are provided in two rows and are arranged inward from the approximately center between the center in the vehicle width direction and both side edges in the vehicle width direction.

[0034] Between each pair of reinforcing ribs 56, reinforcing ribs 57 are provided at the front end, center, and rear end in the vehicle longitudinal direction, extending in the vehicle width direction and connecting the reinforcing ribs 56. At the rear end of the reinforcing rib 56 on the outer side in the vehicle width direction among the pair of reinforcing ribs 56, low reinforcing ribs 58 are provided on the outer side in the vehicle width direction, and are formed in a cross shape in plan view. The lower plate portion 46 of the core upper member 36 is provided with low reinforcing ribs 59 formed in a cross shape in plan view at both ends in the vehicle width direction and at the approximate center of the rear end edge in the vehicle longitudinal direction.

[0035] 5, the lower plate portion 46 of the core upper member 36 is provided with weakened portions 61A, 61B that are configured in a generally U-shape in plan view and open toward the step portion 45 in a portion close to the step portion 45 between each of the two rows of reinforcing ribs 56 and both side edges in the vehicle width direction. Therefore, each of the weakened portions 61A, 61B is configured in a generally U-shape in plan view that opens toward the side where rigidity is increased by the step portion 45 of the lower plate portion 46. As described later, each of the weakened portions 61A, 61B is configured so that when an impact load acts from above on the outer member 28 of the console lid 7, one of the weakened portions 61A, 61B breaks, absorbing and mitigating the impact load (see FIG. 10).

[0036] Here, the schematic configuration of each of the weak portions 61A, 61B will be described with reference to Fig. 6. Note that since each of the weak portions 61A, 61B are formed symmetrically with respect to the vehicle widthwise center position of the core upper member 36, the schematic configuration of the weak portion 61A disposed on the left side in the vehicle width direction with respect to the vehicle front side will be described with reference to Fig. 6. Therefore, the weak portion 61B is configured in a shape obtained by mirror-mirroring the weak portion 61A with respect to the vehicle widthwise center position of the core upper member 36.

[0037] As shown in FIG. 6, the fragile portion 61A has a first notch groove portion 62 having a substantially V-shaped cross section, which extends inward (right side) along the vehicle width direction from a side edge on the left side (outside in the vehicle width direction) of the lower plate portion 46 in the vehicle width direction to a position that is approximately half the distance to the reinforcing rib 56. The fragile portion 61A also has a second notch groove portion 63 having a substantially V-shaped cross section, which extends from an outer end of the first notch groove portion 62 in the vehicle width direction along the outer side edge in the vehicle width direction, that is, along the upper end edge of the vertical wall portion 48, to a lower end edge of the step portion 45 provided on the front side in the vehicle front-rear direction. Therefore, the second notch groove portion 63 extends from an outer end of the first notch groove portion 62 in the vehicle width direction toward a side where the rigidity of the lower plate portion 46 in the vehicle front-rear direction is higher, and reaches the lower end edge of the step portion 45.

[0038] The weak portion 61A has a third notched groove portion 65 having a substantially V-shaped cross section extending from an end portion on the right side in the vehicle width direction (inner side in the vehicle width direction) of the first notched groove portion 62 toward a stepped portion 45 provided on the front side in the vehicle front-rear direction. The third notched groove portion 65 is composed of an oblique notched groove portion 65A extending from an end portion on the right side in the vehicle width direction (inner side in the vehicle width direction) of the first notched groove portion 62 obliquely inward in the vehicle width direction for a predetermined length (for example, substantially the same length as the first notched groove portion 62), and a front notched groove portion 65B extending from a tip of the oblique notched groove portion 65A along a side edge on the outer side in the vehicle width direction to a lower end edge of the stepped portion 45.

[0039] In other words, the diagonal cutout groove portion 65A extends a predetermined length diagonally inward in the vehicle width direction from the end portion on the right side in the vehicle width direction (inner side in the vehicle width direction) of the first cutout groove portion 62 along the direction of maximum breaking stress generated in the lower plate portion 46 when an impact load acts from above on the outer member 28 of the console lid 7. The front cutout groove portion 65B extends from the tip of the diagonal cutout groove portion 65A toward the side of the lower plate portion 46 where rigidity is higher in the front-rear direction of the vehicle, and reaches the lower edge of the step portion 45.

[0040] Therefore, the distance between the second notched groove portion 63 and the front notched groove portion 65B of the third notched groove portion 65 is set to be longer than the length of the first notched groove portion 62. Note that when an impact load acts from above on the outer member 28 of the console lid 7, the direction of maximum breaking stress extending from the end portion on the right side in the vehicle width direction (inner side in the vehicle width direction) of the first notched groove portion 62 toward the side with higher rigidity is determined in advance by CAE (Computer Aided Engineering) or experiments.

[0041] The fragile portion 61A has a fourth notch groove portion 66 having a substantially V-shaped cross section extending along the vehicle width direction from the end portion of the first notch groove portion 62 on the left side in the vehicle width direction (outside in the vehicle width direction) through the vertical wall portion 48 to the substantially center portion in the vehicle width direction of the flange portion 49. The notch depth of the first notch groove portion 62 to the fourth notch groove portion 66 having a substantially V-shaped cross section is formed to a dimension of, for example, about 3 / 5 of the plate thickness of the core upper member 36. As shown in FIG. 6, a slit portion 68 is provided at the substantially center portion in the longitudinal direction of the first notch groove portion 62, which has a length of about half the length of the first notch groove portion 62 and penetrates with a width dimension of the upper end portion in the vehicle up-down direction of the first notch groove portion 62. The slit portion 68 penetrates in a shape such as a substantially oblong shape, a substantially rectangular shape, or a substantially oblong hexagonal shape that is long in the vehicle width direction in a plan view.

[0042] Next, a schematic configuration of a lower surface rib portion 71 and the like provided on the inner lower surface of the upper plate portion 31 of the outer member 28 facing the first notched groove portions 62 of each of the weak portions 61A, 61B of the core upper member 36 will be described with reference to Figures 3, 4, and 7 to 9. As shown in Figures 4, 7 to 9, the inner lower surface of the upper plate portion 31 of the outer member 28 is provided with the lower surface rib portion 71 that protrudes in a rib shape toward the lower plate portion 46 of the core upper member 36 along the vehicle width direction at a position facing the first notched groove portions 62 that constitute the weak portions 61A, 61B of the core upper member 36.

[0043] Both ends of the lower surface rib portion 71 in the vehicle width direction are provided so as to face both side edges in the vehicle width direction of the lower plate portion 46 of the core upper member 36, i.e., each vertical wall portion 48. Also, a pair of rib protrusions 72 are formed which protrude in a rib shape from each lower end of the lower surface rib portion 71 to a predetermined length inward in the vehicle width direction toward the lower plate portion 46 to a predetermined height (for example, a height of about 5 mm to 10 mm).

[0044] 3 and 4, a gap of a predetermined height (e.g., about 1 mm to 2 mm in height) is formed between the lower end surface in the vehicle vertical direction of the lower surface rib portion 71 and each reinforcing rib 56 provided on the lower plate portion 46 of the core upper member 36. Also, a gap of a predetermined height (e.g., about 2 mm to 3 mm in height) is formed between the lower end surface in the vehicle vertical direction of each rib protrusion portion 72 and the upper surface of the lower plate portion 46 of the core upper member 36. Therefore, when the lower end surface in the vehicle vertical direction of the lower surface rib portion 71 abuts on each reinforcing rib 56 substantially horizontally, a gap of a predetermined height (e.g., about 1 mm to 2 mm in height) is formed between the lower end surface in the vehicle vertical direction of each rib protrusion portion 72 and the upper surface of the lower plate portion 46.

[0045] 4 and 9, the outer end of each rib protrusion 72 in the vehicle width direction is provided to face the vertical wall portion 48 provided on the outer side edge of the core upper member 36 in the vehicle width direction. Therefore, the lower surface of each rib protrusion 72 is provided to face the first notched groove portion 62 and the fourth notched groove portion 66 of each weak portion 61A, 61B. The inner end of each rib protrusion 72 in the vehicle width direction is provided to face approximately the center in the vehicle width direction of the slit portion 68 formed in the first notched groove portion 62 of each weak portion 61A, 61B.

[0046] Therefore, as described below, when an impact load acts from above on the outer member 28 of the console lid 7, one of the pair of rib protrusions 72 comes into contact with the first notched groove portion 62 and the fourth notched groove portion 66. Then, the inner end of the rib protrusion 72 in the vehicle width direction enters the slit portion 68 of the first notched groove portion 62, and fracture is initiated from both ends of the slit portion 68 in the vehicle width direction (see FIG. 10).

[0047] 3, 7 and 8, a pair of reinforcing ribs 75 protruding in a rib shape toward the lower plate portion 46 along the vehicle width direction are provided on the lower surface of the upper plate portion 31 of the outer member 28 and the base ends of the inner surfaces of the left and right side wall portions 32. The pair of reinforcing ribs 75 are provided at approximately the center in the vehicle front-rear direction between the lower surface rib portion 71 and a position facing the step portion 45 of the core upper member 36, and at approximately the center in the vehicle front-rear direction between the lower surface rib portion 71 and the rear end edge of the upper plate portion 31.

[0048] In addition, on the underside of the upper plate portion 31 of the outer member 28, reinforcing ribs 76 are provided which protrude in a rib-like manner toward the lower plate portion 46 of the core upper member 36 along the vehicle width direction at two positions between the lower surface rib portion 71 and the rear reinforcing rib 75, and at a position rearward of the rear reinforcing rib 75.

[0049] Further, elastic locking pieces 78 are provided on the inner surface of each of the pair of side wall portions 32 of the outer member 28 at positions facing both ends in the vehicle width direction of each of the pair of reinforcing ribs 75, and at approximately the center in the vehicle front-rear direction between the front reinforcing rib 75 on the front side in the vehicle front-rear direction and the front end edge of the upper plate portion 31. Note that Fig. 7 shows the elastic locking pieces 78 provided on the inner surface of the side wall portion 32 on the left side in the vehicle width direction.

[0050] 5, a pair of flanges 49 provided on both side edges on the outer side in the vehicle width direction of the upper core member 36 are provided with locking holes 79 at positions facing the elastic locking pieces 78 of the outer member 28, into which the elastic locking pieces 78 are inserted for elastic locking. Therefore, by overlapping the outer member 28 over the upper core member 36 and inserting the elastic locking pieces 78 into the opposing locking holes 79, the elastic locking pieces 78 are elastically locked in the locking holes 79, and the outer member 28 is attached to the upper side of the upper core member 36.

[0051] Next, an example in which the weak portion 61A of the core upper member 36 breaks when an impact load acts on the outer member 28 of the console lid 7 from above on the rear side in the vehicle longitudinal direction at a position to the left of the center in the vehicle width direction (see Figs. 3 and 4) will be described with reference to Fig. 10. Note that when an impact load acts on the outer member 28 of the console lid 7 from above on the rear side in the vehicle longitudinal direction at a position to the right of the center in the vehicle width direction, the weak portion 61B of the core upper member 36 breaks in the same manner.

[0052] 3 and 4, when an impact load acts on the outer member 28 of the console lid 7 from above on the rear side in the vehicle longitudinal direction at a position to the left of the center in the vehicle width direction, a rib protrusion 72 formed on the left end side in the vehicle width direction of a lower surface rib portion 71 provided on the lower surface of the outer member 28 collides with the first notched groove portion 62 of the opposing weak portion 61A as shown in Fig. 10. At this time, the end portion on the right side in the vehicle width direction (inner side in the vehicle width direction) of the rib protrusion portion 72 enters the slit portion 68, and the impact load is transmitted to both longitudinal ends of the slit portion 68.

[0053] As a result, as shown in Fig. 10, stress concentration due to the impact load occurs at both longitudinal ends of the slit portion 68, and the first notch groove portion 62 having a substantially V-shaped cross section starts to break reliably from both longitudinal ends of the slit portion 68. When the breakage of the first notch groove portion 62 reaches the end on the left side in the vehicle width direction (outer side in the vehicle width direction), the second notch groove portion 63 and the fourth notch groove portion 66 also having a substantially V-shaped cross section are broken, and the rib protrusion portion 72 enters the broken portion. The breakage of the second notch groove portion 63 propagates upward from the tip end of the second notch groove portion 63 through the step portion 45, and further breaks the reinforcing rib 55 formed in a cross shape in a plan view of the upper plate portion 43.

[0054] Furthermore, when the fracture of the first notched groove portion 62 reaches the end on the right side in the vehicle width direction (inner side in the vehicle width direction), the obliquely notched groove portion 65A of the third notched groove portion 65 is fractured. Then, after the fracture of the obliquely notched groove portion 65A reaches the tip on the obliquely inner side in the vehicle width direction, it is further propagated in the obliquely inner direction in the vehicle width direction, and the lower plate portion 46 is fractured.

[0055] As a result, the first notched groove portion 62, the second notched groove portion 63, the diagonal notched groove portion 65A of the third notched groove portion 65, and the fourth notched groove portion 66 constituting the weak portion 61A provided on the left side in the vehicle width direction of the core upper member 36 are broken, so that the impact load acting on the outer member 28 can be efficiently absorbed and mitigated. Furthermore, the breakage is transmitted from the tip of the diagonal notched groove portion 65A to the diagonal inner portion in the vehicle width direction, and the breakage is transmitted from the tip of the second notched groove portion 63 to the step portion 45 and the upper plate portion 43 on the front-rear direction front side of the vehicle, so that the impact load acting on the outer member 28 can be even more efficiently absorbed and mitigated.

[0056] As described above in detail, in the vehicle console box 1 according to this embodiment, when a static load acts on the outer member 28 of the console lid 7 under normal circumstances, the static load is transmitted to the box body 5 and the like via the core lower member 35 and the core upper member 36 constituting the outer member 28 and the inner member 29. As a result, under normal circumstances, the mechanical rigidity of the vehicle console box 1 during actual use can be ensured.

[0057] Furthermore, when an impact load acts on the outer member 28 of the console lid 7 from above on the rear side in the vehicle front-rear direction, the impact load is transmitted to the opposing weak portion 61A or weak portion 61B via one of a pair of rib protrusions 72 provided on the underside of the outer member 28. Then, the first notched groove portion 62 to the fourth notched groove portion 66 constituting the weak portion 61A or weak portion 61B are broken by the rib protrusion 72, so that the impact load acting on the outer member 28 can be efficiently absorbed and mitigated.

[0058] Further, the pair of weak portions 61A, 61B are provided at positions facing the pair of rib protrusions 72 of the core upper member 36 disposed opposite the lower surface of the outer member 28. As a result, the core upper member 36 having the pair of weak portions 61A, 61B is covered by the outer member 28 and the core lower member 35 constituting the bottom surface portion of the console lid 7, thereby improving the appearance of the console lid 7.

[0059] Furthermore, when an impact load acts on the outer member 28 from above on the rear side in the vehicle front-rear direction, the impact load acts on the first notched groove portion 62 having a substantially V-shaped cross section of the opposing weak portion 61A or weak portion 61B via one of a pair of rib protrusions 72. As a result, the first notched groove portion 62 is broken by the impact load acting on the first notched groove portion 62 via the rib protrusion 72.

[0060] Then, the breakage due to the impact load is transmitted to the second notched groove portion 63 and the third notched groove portion 65, which are connected to both ends in the vehicle width direction of the first notched groove portion 62 and have a generally V-shaped cross section extending toward the side with higher rigidity, and the second notched groove portion 63 and the third notched groove portion 65 break, absorbing and mitigating the impact load. Therefore, the impact load acting on the outer member 28 of the console lid 7 can be efficiently absorbed and mitigated.

[0061] Further, a fourth notched groove portion 66 having a generally V-shaped cross section is provided along the vehicle width direction from the vehicle width direction outer end of the first notched groove portion 62 to a position facing the vehicle width direction outer end of the opposing rib convex portion 72 of the vertical wall portion 48 and the flange portion 49 of the core upper member 36, facing the lower surface of the rib convex portion 72. When an impact load acts on the outer member 28 from above on the rear side in the vehicle front-rear direction, the impact load is transmitted from the vehicle width direction outer end of the first notched groove portion 62 to the fourth notched groove portion 66, and the fourth notched groove portion 66 is broken, so that the impact load is absorbed and alleviated. Therefore, the impact load acting on the outer member 28 of the console lid 7 can be reliably absorbed and alleviated.

[0062] Furthermore, when an impact load acts on the outer member 28 from above on the rear side in the vehicle front-rear direction, the inner end in the vehicle width direction of the rib protrusion 72 enters the slit portion 68, and the first notched groove portion 62 can be reliably broken from both ends in the vehicle width direction of the slit portion 68. As a result, the impact load is transmitted to the second notched groove portion 63 and the third notched groove portion 65, which are connected to both ends in the vehicle width direction of the first notched groove portion 62 and extend toward the side with higher rigidity, and the second notched groove portion 63 and the third notched groove portion 65 are broken, and the impact load is absorbed and mitigated.

[0063] Furthermore, the impact load is also transmitted to the fourth notched groove portion 66 extending outward in the vehicle width direction from the outer end of the first notched groove portion 62 in the vehicle width direction, causing the fourth notched groove portion 66 to break, thereby absorbing and mitigating the impact load. Therefore, by providing the slit portion 68 at a position facing the inner end of the rib protrusion portion 72 in the vehicle width direction of the first notched groove portion 62, the first notched groove portion 62 to the fourth notched groove portion 66 can be broken from both ends of the slit portion 68 in the vehicle width direction, and the impact load acting on the outer member 28 of the console lid 7 can be more reliably absorbed and mitigated.

[0064] In addition, the core upper member 36 has a higher rigidity in the front-rear direction of the vehicle than the first notched grooves 62 of the pair of fragile portions 61A and 61B due to the step portion 45 provided over the entire width in the vehicle width direction. Therefore, the second notched groove portion 63 and the third notched groove portion 65 extend from both ends of the first notched groove portion 62 in the vehicle width direction to the step portion 45, that is, toward the front side in the vehicle front-rear direction. As a result, when an impact load acts on the rear side of the console lid 7 in the vehicle front-rear direction from above, the impact load is transmitted to the second notched groove portion 63 and the third notched groove portion 65 formed in the impact load direction, and the console lid 7 is broken. Therefore, the impact load acting on the outer member 28 of the console lid 7 from above on the rear side in the vehicle front-rear direction can be reliably absorbed and mitigated.
