Description

[Technical field]

[0001] The present invention relates to a front trunk structure. [Background technology]

[0002] 2. Description of the Related Art In recent years, electric vehicles have become more popular, and as power units that drive the front wheels have become smaller, a front trunk may be attached below a front hood at the front of the vehicle.

[0003] The front trunk is disposed at the front of the vehicle, on the rear side of the bumper, the air intake, or the cooling device. In this case, the front trunk is disposed at a position set back from the front end of the vehicle. Therefore, when a user puts or takes out luggage in or out of the front trunk, a part of the body may come into contact with the front bumper face, making it difficult to put or take out luggage placed at the bottom of the front trunk.

[0004] As a technology to address the above-mentioned issues, a technology has been disclosed for a sliding double floor for a trunk room, which is configured in a vehicle equipped with a trunk lid that opens to the height of the trunk floor in order to ensure the opening dimensions of the trunk room, and which comprises a sliding movable floor that is guided and slid by rollers in guide grooves in the trunk floor and trunk side inner panel, and a wire that links the sliding of the sliding movable floor to the opening and closing of the trunk lid (see, for example, Patent Document 1).

[0005] Furthermore, when an electric vehicle is hit by a frontal collision, it is necessary to reduce the impact on high-voltage devices such as the power unit and inverter that drive the front wheels by absorbing the impact in the front vehicle structure.

[0006] As a technology for addressing the above-described problems, a first weak portion and a second weak portion are formed in an engine hood inner panel of an engine hood (front hood) along the vehicle width direction. The first weak portion is provided in a division on the front side of the vehicle that divides the engine hood into approximately three equal parts in the front-to-rear length, and has a convex shape toward the top of the vehicle. The second weak portion is provided in a division on the rear side of the vehicle that divides the engine hood into approximately three equal parts in the front-to-rear length, and has a convex shape toward the top of the vehicle. A technology has been disclosed in which the cross-sectional shapes of the first weak portion and the second weak portion as viewed in the vehicle width direction are semicircular with the opening facing downward, and the depth of the first weak portion is shallower than the depth of the second weak portion (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 2-113536 [Patent Document 2] Japanese Patent Application Publication No. 9-226629 Summary of the Invention [Problem to be solved by the invention]

[0008] In the technology described in Patent Document 1, the trunk is moved in the longitudinal direction of the vehicle when the trunk hood is opened. However, the technology described in Patent Document 1 does not take into account the movement of the trunk in the vertical direction of the vehicle when the trunk hood is opened, which means there is a risk that it may be difficult to load and unload luggage placed at the bottom of the trunk.

[0009] Furthermore, in the technology described in Patent Document 2, when a collision occurs from the front of the vehicle, the vehicle engine hood (vehicle front hood) bends starting from the first weak portion and the second weak portion, thereby shortening the front-to-rear length of the vehicle front hood at maximum deformation.

[0010] However, in the vehicle front hood described in Patent Document 2, for example, when a front trunk is provided on the underside of the vehicle front hood of an electric vehicle, there is a problem in that the behavior of the front trunk in the event of a collision from the front of the vehicle is not taken into consideration, which may result in the front trunk interfering with the high-voltage device.

[0011] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide a front trunk structure that improves the convenience of the front trunk and reduces interference with vehicle equipment in the event of a collision from the front of the vehicle. [Means for solving the problem]

[0012] Form 1: One or more embodiments of the present invention propose a front trunk structure comprising a pair of left and right front side frames extending in the fore-and-aft direction of the vehicle on both sides in the vehicle width direction of the vehicle, a front hood section having weak portions on both sides in the vehicle width direction, a front trunk section arranged on the inside of the front side frames in the vehicle width direction and having a guide groove section extending in the fore-and-aft direction of the vehicle on its underside, a sliding rod section arranged slidably in the fore-and-aft direction of the vehicle on the underside of the front trunk section, and having a flexible member that can be bent and deformed connected to its rear side section, a sliding guide section arranged on the vehicle rear side of the sliding rod section and with which the flexible member slidably abuts, and a connecting section that is rotatably connected to the flexible member on the underside of the front trunk section and slidably fitted into the guide groove section of the front trunk section.

[0013] Form 2: One or more embodiments of the present invention propose a front trunk structure in which a hood fixing portion is further provided on the vehicle front side of the front hood portion, and an operating lever portion connected to the hood fixing portion is provided on the vehicle front side of the sliding rod portion.

When the front hood part FF is closed, the operating lever part 330 is engaged with the operating lever housing 340.

[0038] (Regarding the sliding guide portion 400) As shown in FIG. 5, the sliding guide portion 400 is disposed on the vehicle rear side of the sliding rod portion 300, and the flexible member 320 is in slidable contact therewith. The sliding guide portion 400 is provided on the cradle frame portion 30 and slides the sliding rod portion 300. The sliding guide portion 400 is formed in a substantially flat plate shape using a member such as metal or resin, and extends in the front-rear direction of the vehicle. The sliding guide portion 400 is bent in an arc shape toward the upper side of the vehicle on the rear side of the cradle longitudinal portion 40. The sliding guide portion 400 is further bent in an arc shape toward the front side of the vehicle on the upper side of the cradle frame portion 30.

An elongated hole is provided on the vehicle upper side of the connecting shaft CS in the slide member 520. The slide shaft SS is disposed to pass through the elongated hole. A flexible member 320 of the sliding rod portion 300 is rotatably connected to the connecting shaft CS. The upper end of the slide member 520 on the vehicle upper side is slidably fitted into the guide groove portion 220 in the front trunk portion 200 .

[0042] <Actions and Effects> In the front trunk structure 100 according to this embodiment configured as described above, the operation when the front hood portion FF is opened and the operation when the vehicle V is hit from the front side of the vehicle will be described with reference to FIGS.

[0043] (When loading and unloading luggage into the front trunk 200) As shown in FIG. 6(a), when a user loads or unloads luggage into the front trunk section 200, the user releases the locked state of the hood fixing portion LK provided on the front side of the vehicle of the front hood section FF, and rotates the front hood section FF in the direction indicated by the arrow AR1, with the opening / closing axis TR as the rotation axis.

[0044] By releasing the locked state of the hood fixing part LK, one end of the wire WR connected to the hood fixing part LK is pulled, and the locked state of the operating lever housing part 340 connected to the other end of the wire WR is released. Then, the operating lever part 330 provided at the vehicle front end part of the operating rod 310 rotates in the direction indicated by the arrow AR2 as shown in Fig. 6(b) and is fixed to the vehicle underside of the operating rod 310 in the sliding rod part 300.

[0045] When a user pushes in the operating lever portion 330 in the direction indicated by the arrow AR3, for example, using the toe, the operating rod 310 slides toward the rear of the vehicle. The flexible member 320 provided on the rear side of the operating rod 310 abuts against the sliding guide portion 400 and slides along the sliding guide portion 400 while deforming. Link member 510 connected to flexible member 320 rotates in the direction indicated by arrow AR4 with fixed axis FS as the center of rotation, and pushes up slide member 520 connected to connecting shaft CS in the direction indicated by arrow AR5. The upper end of slide member 520 on the vehicle side moves along a path indicated by dashed arrow AR6, and slides along guide groove 220 in front trunk section 200 that abuts against the upper side of the vehicle. Then, the slide member 520 pushes up the front trunk section 200 in the direction indicated by the arrow AR7.

[0046] As shown in FIG. 6(c), when the user further presses the operating lever portion 330 in the direction indicated by the arrow AR3, the upper end of the sliding member 520 on the vehicle side moves further along the trajectory indicated by the dashed arrow AR6. The vehicle front side of front trunk section 200 is tilted in the direction indicated by arrow AR8 due to the inclination of guide groove section 220 in front trunk section 200.

[0047] As described above, when the user opens the front hood portion FF and uses the operating lever portion 330 to push the operating rod 310 in the sliding rod portion 300 toward the rear of the vehicle, the front trunk portion 200 rises toward the top of the vehicle and tilts toward the front of the vehicle.

[0048] (When a collision occurs from the front of vehicle V) As shown in FIG. 7(a), when an impact object CO collides with a vehicle V from the front side of the vehicle, collision energy is transmitted to the bumper beam BP and the radiator frame portion 60 from the direction indicated by the arrow BR1.

[0049] As shown in Figure 7 (b), the collision energy transmitted to the bumper beam BP and the radiator frame portion 60 crushes the bumper beam BP and the radiator frame portion 60, while pushing the front side frame 20 and the upper frame 50 toward the rear of the vehicle, and the operating rod 310 in the sliding rod portion 300 is pushed toward the rear of the vehicle. The front hood section FF is pushed toward the rear of the vehicle by the collision energy transmitted to the radiator frame section 60, and is bent at a weak point WP provided on the front hood section FF. The hood fixing section LK on the front hood section FF is separated from the front hood section FF while the locked state is not released. Then, the operating lever section 330 is fixed to the vehicle underside of the operating rod 310.

[0050] When the operating rod 310 is pushed in the direction of the arrow BR2 by the collision object CO, the operating rod 310 slides toward the rear of the vehicle. The flexible member 320 provided on the vehicle rear side of the operating rod 310 abuts against the sliding guide portion 400 and slides along the sliding guide portion 400 while deforming. The link member 510 connected to the flexible member 320 rotates in the direction indicated by the arrow BR4 with the fixed axis FS as the center of rotation, and pushes up the slide member 520 connected to the connecting shaft CS in the direction indicated by the arrow BR5. The upper end of slide member 520 moves along the path indicated by dashed arrow BR6, and slides along guide groove 220 in front trunk section 200 that is in contact with the upper side of the vehicle. Then, slide member 520 pushes up front trunk section 200 in the direction indicated by arrow BR7.

[0051] Furthermore, when collision energy is transmitted from the colliding object CO, as shown in FIG. 7(c), the collision energy further pushes the operating rod 310 in the direction indicated by the arrow BR3, causing the upper end of the slide member 520 to move further along the trajectory indicated by the dashed arrow BR6. The front hood section FF is further bent toward the upper side of the vehicle at a weak portion WP provided in the front hood section FF. Then, a space PS (cross-hatched portion in FIG. 7(c)) is formed below the front hood section FF, allowing the front trunk section 200 to move. The vehicle front side of front trunk section 200 tilts toward the vehicle front side due to the inclination of guide groove section 220 in front trunk section 200. Then, slide member 520 pushes up front trunk section 200 in the direction indicated by arrow BR7. As front trunk section 200 tilts toward the vehicle front side, the vehicle rear side of front trunk section 200 rotates in the direction indicated by arrow BR8 and moves in a direction away from drive section DU.

[0052] As described above, when an impact object CO collides with the front of the vehicle V, the operating rod 310 in the sliding rod section 300 is pushed toward the rear of the vehicle by the impact object CO, and the front trunk structure 100, by linking the sliding rod section 300, the sliding guide section 400, and the connecting section 500, moves the front trunk section 200 toward the space PS formed on the upper side of the vehicle where it does not interfere with the drive section DU.

[0053] Then, as the movement of the colliding object CO stops and the input of the collision energy ends, the absorption of the collision energy by the deformation of the frame portion FL forming the skeleton of the vehicle V in the vehicle body front structure S ends.

[0054] As described above, the front trunk structure 100 of this embodiment comprises a pair of left and right front side frames 20 extending in the front-rear direction of the vehicle on both sides in the vehicle width direction of the vehicle V, a front hood section FF having weak sections WP provided on both sides in the vehicle width direction, a front trunk section 200 arranged on the inside of the front side frames 20 in the vehicle width direction and having a guide groove section 220 extending in the front-rear direction of the vehicle on its underside, a sliding rod section 300 arranged slidably in the front-rear direction of the vehicle on the underside of the front trunk section 200, and having a bendable and deformable flexible member 320 connected to its rear side, a sliding guide section 400 arranged on the vehicle rear side of the sliding rod section 300 and with which the flexible member 320 slidably abuts, and a connecting section 500 that is rotatably connected to the flexible member 320 on the underside of the vehicle of the front trunk section 200 and slidably fitted into the guide groove section 220 of the front trunk section 200. That is, when a user loads or unloads luggage into the front trunk 200, the user pushes in the operating lever 330 of the sliding rod 300 toward the rear of the vehicle, causing the sliding rod 300 to slide toward the rear of the vehicle. The flexible member 320 provided on the vehicle rear side of the sliding rod portion 300 slides while deforming along the sliding guide portion 400, and pushes up the slide member 520 connected to the connecting shaft CS toward the upper side of the vehicle via the link member 510 connected to the flexible member 320. The slide member 520 slides along the guide groove 220 in the front trunk section 200 that is in contact with the upper side of the vehicle, and the slide member 520 pushes the front trunk section 200 up towards the upper side of the vehicle. The vehicle front side of front trunk section 200 is inclined toward the vehicle front side due to the inclination of guide groove section 220 in front trunk section 200. Therefore, when a user wants to put something in or take something out of the front trunk section 200, the user opens the front hood section FF and pushes the operating lever section 330 of the sliding rod section 300 toward the rear of the vehicle, whereby the front trunk section 200 rises toward the upper side of the vehicle and can be tilted toward the front side of the vehicle. Then, by lifting the bottom surface of the front trunk section 200 toward the upper side of the vehicle, the user can easily see inside the front trunk section 200 and can easily put something in or take something out of the bottom surface of the front trunk section 200. When an object CO collides with the front of the vehicle V, the collision energy is transmitted to the bumper beam BP and the radiator frame portion 60, causing the operating rod 310 in the sliding rod portion 300 to be pushed toward the rear of the vehicle, along with the front side frame 20 and the upper frame 50. The front hood portion FF is bent toward the upper side of the vehicle at the weak portion WP, and a space PS is formed. The flexible member 320 provided on the vehicle rear side of the sliding rod portion 300 abuts against the sliding guide portion 400 and slides while deforming along the sliding guide portion 400, and pushes up the slide member 520 connected to the connecting shaft CS toward the upper side of the vehicle via the link member 510 connected to the flexible member 320. The slide member 520 slides along the guide groove 220 in the front trunk section 200 that is in contact with the upper side of the vehicle, and the slide member 520 pushes the front trunk section 200 up toward the upper side of the vehicle. The front side of the front trunk section 200 tilts toward the front side of the vehicle due to the inclination of the guide groove 220 in the front trunk section 200. As front trunk section 200 tilts toward the front of the vehicle, the rear side of front trunk section 200 rotates toward space PS formed above the vehicle, and moves in a direction away from drive section DU. Therefore, when an impact object CO impacts the front of the vehicle V, the sliding rod portion 300 is pushed toward the rear of the vehicle by the impact object CO, and the sliding rod portion 300, the sliding guide portion 400, and the connecting portion 500 work together to enable the front trunk structure 100 to move the front trunk portion 200 toward the space PS formed on the upper side of the vehicle where it does not interfere with the drive portion DU. This improves the convenience of the front trunk and reduces interference with vehicle devices in the event of a frontal collision of the vehicle.

[0055] The front trunk structure 100 according to this embodiment further includes a hood fixing part LK on the vehicle front side of the front hood part FF, and an operating lever part 330 connected to the hood fixing part LK is provided on the vehicle front side of the sliding rod part 300. That is, when the user wants to put something in or take something out of the front trunk portion 200, the user releases the locked state of the hood fixing portion LK and opens the front hood portion FF. The hood fixing part LK is released from the locked state, and the wire WR connected to the hood fixing part LK is pulled, thereby releasing the locked state of the operating lever part 330 in the operating lever housing part 340. Then, the operating lever part 330 provided at the vehicle front end part of the sliding rod part 300 rotates towards the vehicle front side and is fixed to the vehicle underside of the sliding rod part 300. Therefore, when a user loads or unloads luggage in the front trunk section 200, the operating lever section 330 is fixed to the underside of the vehicle when the front hood section FF is opened, so that the user can easily operate the operating lever section 330. Then, by the user lifting the bottom surface of the front trunk section 200 toward the upper side of the vehicle, the user can easily view the inside of the front trunk section 200 and can easily load or unload luggage from the bottom surface of the front trunk section 200. When an impact object CO hits the vehicle V from the front side, the locked state of the hood fixing part LK is not released, and therefore the locked state of the operating lever part 330 in the operating lever housing part 340 is not released. Therefore, in the event that an impact object CO collides with the front of the vehicle V, the operating lever portion 330 is fixed to the underside of the vehicle of the sliding rod portion 300, so that the front trunk structure 100 can be fixed in a position that does not interfere with the vehicle equipment around the operating lever portion 330. This improves the convenience of the front trunk and reduces interference with vehicle devices in the event of a frontal collision of the vehicle.
