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, for example, 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 in 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). [Prior art documents] [Patent documents]

[0039] <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 will be described with reference to Figs.

[0040] (When loading and unloading luggage into the front trunk 200) As shown in FIG. 5(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.

[0041] When the hood fixing part LK is released from the locked state, the wire WR connected to the hood fixing part LK is pulled, and the operating lever housing part 340 connected to the wire WR is released from the locked state. 5(b), an operating lever portion 330 provided on the vehicle front end of the operating rod 310 protrudes in the direction indicated by the arrow AR2, and is fixed to the lower side of the sliding portion 300 in the vehicle.

[0042] 5(a), when a user, for example, uses the toe to push the operating lever portion 330 toward the rear of the vehicle in the direction indicated by the arrow AR3, the sliding portion 300 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.

[0043] 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 the slide member 520 on the vehicle side slides along the guide portion 220 in the front trunk portion 200 while moving along a path indicated by a dashed arrow AR6. Then, the slide member 520 pushes up the front trunk section 200 in the direction indicated by the arrow AR7.

[0044] When the user further presses the operating lever portion 330 in the direction indicated by the arrow AR3 as shown in FIG. 6(a), the upper end of the sliding member 520 on the vehicle side further moves along the trajectory indicated by the dashed arrow AR6. The vehicle front side of front trunk section 200 is tilted toward the vehicle front side in the direction indicated by arrow AR8 due to the inclination of guide section 220 in front trunk section 200.

[0045] 6(b), when the user pushes the operating lever portion 330 toward the rear of the vehicle, the operating rod stop portion 350 provided on the operating rod 310 fits into a stop groove 360 ​​provided on the vehicle underside of the cradle frame portion 30. When the user depresses the operating lever portion 330 in the direction indicated by the arrow AR9, the operating lever portion 330 fixes the operating rod stop portion 350. When the operating rod stop portion 350 fits into the stop groove 360, the operating lever portion 330 comes into contact with the operating rod stop portion 350, thereby restricting the rotation of the operating rod stop portion 350 toward the front of the vehicle. By restricting the rotation direction of the operating rod stop portion 350, the operating rod 310 is fixed in the position to which it has been moved. And the sliding portion 300 is fixed in the position to which it has been moved. By fixing the sliding portion 300 in the position to which it has been moved, the front trunk portion 200 is fixed in the raised position to which the user has moved it and at an inclination toward the front of the vehicle. When the stop groove 360 ​​has multiple groove portions, the sliding portion 300 is fixed in a position desired by the user, and the front trunk portion 200 is fixed in an elevated position and inclined toward the front of the vehicle desired by the user.

[0046] As described above, in the front trunk structure 100, when the user opens the front hood section FF and slides the operating lever section 330 toward the rear of the vehicle, the front trunk section 200 rises toward the upper side of the vehicle and tilts toward the front of the vehicle. Then, the sliding section 300 is fixed in position to the position to which the user has moved, so that the front trunk section 200 is stably fixed to the raised position to which the user has moved and tilted toward the front of the vehicle.

[0047] As described above, the front trunk structure 100 according to 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 cradle frame portion 30 provided on the underside of the front side frames 20, a front hood portion FF having a hood fixing portion LK provided on the front side of the vehicle, a front trunk portion 200 disposed on the inside of the front side frames 20 in the vehicle width direction, and a cradle frame portion 30 disposed on the underside of the front trunk portion 200 so as to be slidable in the front-rear direction of the vehicle and interlocking with the front trunk portion 200. The front trunk structure 100 includes a sliding portion 300 that engages with the cradle frame portion 300, and at least one stop groove 360 ​​extending in the vehicle width direction is provided on the underside of the vehicle on both sides of the cradle frame portion 30 in the vehicle width direction, and the sliding portion 300 includes an operating rod 310 disposed on the underside of the vehicle of the front trunk portion 200, an operating lever portion 330 that is rotatably provided on the vehicle front side of the operating rod 310 and connected to the hood fixing portion LK, and an operating rod stop portion 350 that limits the movement of the operating rod 310 when the operating rod 310 engages with the stop groove 360. That is, when a user puts or takes luggage in or out of front trunk section 200, the user pushes operating lever section 330 toward the rear of the vehicle, causing operating rod 310 to slide toward the rear of the vehicle. Flexible member 320 provided on the rear side of operating rod 310 pushes slide member 520 upward toward the vehicle via link member 510. Slide member 520 slides along guide section 220 in front trunk section 200, and pushes front trunk section 200 upward toward the vehicle. The front side of front trunk section 200 tilts toward the front of the vehicle due to the inclination of guide section 220 in front trunk section 200. Then, the operating rod stop portion 350 fits into the stop groove 360, and the operating lever portion 330 abuts against the operating rod stop portion 350, thereby restricting the rotation direction of the operating rod stop portion 350. By restricting the rotation direction of the operating rod stop portion 350, the positional movement of the operating rod 310 toward the front of the vehicle is restricted. The front trunk portion 200 is stably fixed in the raised position to which it has been moved and at an inclination toward the front of the vehicle. 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 toward the rear of the vehicle, thereby allowing the user to lift the front trunk section 200 toward the upper side of the vehicle and tilt it toward the front of the vehicle. Then, the user can stably fix the front trunk section 200 in the raised position to which it has been moved and at an inclination toward the front of the vehicle. A user can easily view the inside of the front trunk portion 200 and can easily put in and take out luggage from the bottom of the front trunk portion 200. This improves the convenience of the front trunk.

[0048] <Second embodiment> The vehicle body front structure SA including the configuration of the front trunk structure 100A according to this embodiment will be described with reference to Figs.

[0049] (Regarding the SA front body structure) In the vehicle V, a vehicle body front structure SA is configured at the front of a cabin CA which serves as the interior of the vehicle where the occupants sit. The vehicle body front structure SA includes a drive unit DU, a frame unit FL, and a front trunk structure 100A.

[0050] (Regarding front trunk structure 100A) As shown in FIG. 7, the front trunk structure 100A includes a front hood portion FF, a front trunk portion 200, and a sliding portion 300A.

[0051] (Regarding the sliding portion 300A) The sliding portion 300A is configured to include an operating rod 310A, a flexible member 320A, an operating lever portion 330A, an operating lever accommodating portion 340, an operating rod stop portion 350, a stop groove 360, a sliding guide portion 400, a connecting portion 500, and an operating rod drive portion 600.

[0052] The operating rod 310A is made of a metal member or the like and is formed in a substantially U-shape when viewed from the underside of the vehicle. A flexible member 320A is connected to the vehicle rear side portion of the operating rod 310A.

[0053] Flexible member 320A is made of metal, resin, or the like and is provided so as to be capable of bending and deforming. Flexible member 320A is connected to operating rod 310A at the front end of the vehicle and is connected to connecting portion 500 at the rear end of the vehicle. Flexible member 320A is in slidable contact with sliding guide portion 400. An operating rod driving section 600 (described later) is connected to the vehicle rear side of the flexible member 320A. The flexible member 320A passes through the operating rod driving section 600, and a link member 510 of the connecting section 500 is rotatably connected to the vehicle rear side of the operating rod driving section 600.

[0054] The operating lever portion 330A is rotatably provided on the vehicle front end of the operating rod 310A, and is biased toward the vehicle front by, for example, a spring (not shown) or the like. The operating lever portion 330A is provided with a start switch SW for starting the movement of the sliding portion 300A in the front-rear direction of the vehicle. The start switch SW is provided, for example, on the upper side of the vehicle of the operating rod 310A, extending in the vehicle width direction. The start switch SW is biased, for example, toward the upper side of the vehicle, and when the start switch SW is pressed toward the lower side of the vehicle, the start switch SW transmits an ON signal to the operating rod drive unit 600.

[0055] (Regarding the operating rod drive unit 600) The operating rod driving part 600 is provided in the cradle longitudinal passage part 40, for example, as shown in Fig. 8. The operating rod driving part 600 includes a motor part 610 that drives the operating rod 310A and a flexible member sliding part 620, and is connected to the start switch SW by a wiring cord (not shown). For example, when the operating rod driving unit 600 receives an ON signal from the start switch SW, the operating rod driving unit 600 rotates the gear unit 630 fixed to the motor unit 610 to drive the flexible member sliding unit 620, thereby sliding the operating rod 310A toward the rear of the vehicle. When the operating rod driving unit 600 receives an ON signal again from the start switch SW, the operating rod driving unit 600 stops the rotation of the motor unit 610, thereby stopping the sliding unit 300. For example, when the operating rod driving part 600 continuously receives an ON signal from the start switch SW, the operating rod driving part 600 drives the flexible member sliding part 620 by rotating the gear part 630 fixed to the motor part 610 in the reverse direction, and slides the sliding part 300 toward the front of the vehicle. When the operating rod driving part 600 further receives an ON signal from the start switch SW, the operating rod driving part 600 stops the rotation of the motor part 610, thereby stopping the sliding part 300.

[0056] <Actions and Effects> In the front trunk structure 100A according to this embodiment configured as described above, the operation when the front hood portion FF is opened will be described with reference to FIG.

[0057] (When loading and unloading luggage into the front trunk 200) As shown in Figure 9, 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 located 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 BR1, with the opening / closing axis TR as the rotation axis.

[0058] By releasing the locked state of the hood fixing part LK, 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 wire WR is released. Then, the operating lever part 330A provided at the vehicle front end part of the operating rod 310A protrudes towards the vehicle underside and is fixed to the vehicle underside of the operating rod 310A.

[0059] When the user presses the start switch SW provided on the operation lever part 330A, for example, with the toe, the operation rod drive part 600 is actuated, and the operation rod 310A slides in the direction indicated by the arrow BR2. The flexible member 320A provided on the vehicle rear side of the operation rod 310A abuts against the sliding guide part 400, and slides while deforming along the sliding guide part 400 in the direction indicated by the arrow BR3.

[0060] The flexible member 320A pushes up the slide member 520 connected to the connecting shaft CS in the direction indicated by the arrow BR4. The upper end of slide member 520 on the vehicle side moves along a path indicated by dashed arrow BR5, and slides along guide portion 220 in front trunk section 200 that abuts against the upper side of the vehicle. Then, slide member 520 pushes up front trunk section 200 in the direction indicated by arrow BR7. Then, due to the inclination of guide section 220 in front trunk section 200, the vehicle front side of front trunk section 200 tilts toward the vehicle front side in the direction indicated by arrow BR7.

[0061] As the operating rod 310A moves toward the rear of the vehicle, the operating rod stop portion 350 provided on the operating rod 310A fits into the stop groove 360 ​​provided on the vehicle underside of the cradle frame portion 30. When the user presses the start switch SW again, the operating rod drive portion 600 stops the movement of the operating rod 310A, and the operating rod 310 is fixed in the position to which it was moved. By fixing the operating rod 310A in the position where the user has stopped it, the front trunk section 200 is fixed in the raised position where the user has stopped it, and inclined toward the front of the vehicle.

[0062] As described above, in the front trunk structure 100A, when the user opens the front hood portion FF and presses the start switch SW provided on the operation lever portion 330A, the operation rod drive portion 600 is actuated, and the operation rod 310A slides toward the rear side of the vehicle. Then, as the operation rod 310A slides toward the rear side of the vehicle, the front trunk portion 200 rises toward the upper side of the vehicle and tilts toward the front side of the vehicle. When the user presses the start switch SW again, the operation rod drive portion 600 stops, and the operation rod 310A is fixed in the stopped position. Then, the front trunk portion 200 is fixed in the raised position where the user stopped it and tilted toward the front side of the vehicle.

[0063] As described above, in the front trunk structure 100 according to this embodiment, the sliding part 300A is further provided with an operating rod drive part 600 having a motor part 610 that drives the operating rod 310A, and the operating lever part 330A as the operating lever part is provided with a start switch SW that drives the operating rod drive part 600. That is, in front trunk structure 100, by pressing start switch SW provided on operation lever section 330A, operation rod drive section 600 is actuated to drive sliding section 300A, so that front trunk section 200 rises toward the upper side of the vehicle and tilts toward the front side of the vehicle. When the user presses start switch SW again, operation rod drive section 600 stops, and sliding section 300A is fixed in the stopped position. Therefore, the user can fix the front trunk section 200 in the raised position where the user has stopped it, and at an inclination toward the front of the vehicle. This improves the convenience of the front trunk.

[0064] In the second embodiment, the front trunk section 200 is fixed by fitting the operating rod stop section 350 into the stop groove 360, but a torque limiter section that limits the rotation of the driving motor may be provided as the operating rod stop section in the operating rod drive section 600. The torque limiter section limits the rotation of the motor and fixes the operating rod 310A, so that the front trunk structure 100A can fix the front trunk section 200 at the raised position stopped by the user and at an inclination toward the front of the vehicle. This improves the convenience of the front trunk.

[0065] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and designs that do not deviate from the gist of the present invention are also included. [Explanation of symbols]
