[0014] (6) In the front trunk structure described in any one of (1) to (5), a motor as a power source for propelling the vehicle may be disposed at a position on the exterior side of the storage compartment relative to the rear wall portion.

[0015] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 3. In this embodiment, a front trunk structure 100 of a vehicle 1 is illustrated. Each figure will be described with the arrow direction FR as the forward direction, the arrow direction RR as the rearward direction, the arrow direction U as the upward direction, the arrow direction D as the downward direction, the arrow direction L as the leftward direction, and the arrow direction R as the rightward direction. The left-right direction may also be referred to as the vehicle width direction.

[0016] As shown in Fig. 1, the vehicle 1 is located forward of the vehicle cabin S1 as an interior space in which passengers ride, and includes a front portion 1A that protrudes forward. The front portion 1A includes tires T arranged on both sides in the vehicle width direction, a motor M as a power source that rotates the tires T to run the vehicle 1, and a front trunk structure 100. The tires T and the motor M are sound-generating bodies that generate sound as the vehicle 1 runs. The vehicle 1 is an electric vehicle, and does not include an engine as a power source to run the vehicle 1.

[0017] The front trunk structure 100 is disposed above the tires T and the motor M and comprises an upper wall portion 15 constituting a wall extending in the vehicle fore-and-aft direction and in the vehicle width direction, a lid portion (hood portion) 10 that can be flipped up relative to the upper wall portion 15, and a recess 20 attached to the central portion of the upper wall portion 15 and having a concave shape that opens upward.

[0018] The lid 10 can be changed between an open state (see FIG. 1) in which it is flipped up against the upper wall 15 to open the opening (opening edge 20A) of the recess 20, and a closed state (see FIG. 3) in which it faces the upper wall 15 and closes the opening (opening edge 20A) of the recess 20. In the open state, the lid 10 can maintain its position by bracing the support 13. In the closed state, the opening of the recess 20 is covered by the lid 10, and a storage chamber S2 is formed between the recess 20 and the lid 10. The storage chamber S2 can store luggage. The opening edge 20A of the recess 20 is an elastic part having elasticity (for example, made of a material softer than the upper wall 15), and can be in close contact with the lid 10 in the closed state.

[0019] The recess 20 is disposed in front of the vehicle compartment S1 and has a shape recessed downward. As shown in Fig. 2 and Fig. 3, the recess 20 includes a bottom wall portion 21 having a rectangular plate shape when viewed from above and extending in the front-rear and left-right directions, two side wall portions 24 rising from both ends in the width direction of the bottom wall portion 21 and having a rectangular plate shape when viewed from the side and extending in the front-rear and up-down directions, forming walls of the recess 20 in the vehicle width direction, a rear wall portion 27 rising from the rear end of the bottom wall portion 21 and having a rectangular plate shape when viewed from the front and extending in the vehicle width direction and up-down directions, forming the rear wall of the recess 20, and a front wall portion 29 rising from the front end of the bottom wall portion 21 and having a rectangular plate shape when viewed from the rear and extending in the vehicle width direction and up-down directions, forming the front wall of the recess 20. A motor M is disposed behind the rear wall portion 27 (at a position on the outside of the accommodation room S2 relative to the rear wall portion 27).

[0020] A sound-absorbing skin may be attached to the surface (the surface facing the interior side of the storage room S2) of each of the walls 21, 24, 27, and 29. The material of such a skin is not particularly limited, but nonwoven fabric, woven fabric, etc. can be used.

[0021] The upper ends of the two side walls 24, the upper end of the rear wall 27, and the upper end of the front wall 29 form the opening edge 20A of the recess 20. The bottom wall 21 has a left end 21A. The two side walls 24 and the rear wall 27 have lower ends 24A, 27A, respectively. The left end 21A of the bottom wall 21 is the portion where the lower end 24A of the left side wall 24 is connected, and serves as a base from which the lower end 24A stands up. A hole 30 is provided in the center portion of the left end 21A of the bottom wall 21 in the front-to-rear direction, penetrating in the up-down direction (the indoor / outdoor direction of the storage room S2), which is the thickness direction of the bottom wall 21.

[0022] The hole 30 has a circular shape when viewed from above. As shown in FIG. 3, the hole 30 includes a main body 31 having a cylindrical shape in the vertical direction, an inner opening 32 that is an upper end portion of the main body 31 and opens to the indoor side of the accommodation chamber S2, and an outer opening 33 that is a lower end portion of the main body 31 and opens to the outdoor side of the accommodation chamber S2. The accommodation chamber S2 is connected to an outer space S3 on the outdoor side through the hole 30. The outer space S3 may be one or both of a space in which the motor M is disposed (a space inside the vehicle in the front part 1A) and a space in which the tire T is disposed or a space under the floor (a space outside the vehicle). When sound is generated in the outer space S3, the air in the accommodation chamber S2 that is connected to the outer space S3 through the hole 30 resonates (Helmholtz resonance), so that the sound generated in the outer space S3 can be absorbed and reduced.

[0023] Next, the effect of this embodiment will be described. In this embodiment, a front trunk structure 100 of a vehicle 1 is shown, which is provided with a recess 20 that is disposed in front of a vehicle interior S1 and opens upward, and a storage compartment S2 is formed by covering the opening of the recess 20 with a lid 10, the recess 20 includes a bottom wall 21, a side wall 24 that rises from the bottom wall 21 and forms a wall of the recess 20 in the vehicle width direction, and a rear wall 27 that rises from the bottom wall 21 and forms a rear wall of the recess 20, and the bottom wall 21 is provided with a hole 30 that is formed to penetrate the storage compartment S2 in the indoor and outdoor directions.

[0024] According to such a front trunk structure 100, the storage compartment S2 capable of storing luggage in the front of the vehicle interior S1 and the hole 30 can function as a resonator capable of absorbing and reducing sound generated on the exterior side. Since the hole 30 is provided in the bottom wall 21, the storage compartment S2 can effectively absorb wind noise generated under the floor of the vehicle 1, for example. This makes it possible to provide a comfortable interior space of the vehicle. Furthermore, since the hole 30 is provided in the bottom wall 21, even if water enters the storage compartment S2, it can be drained through the hole 30 to the exterior side of the storage compartment S2.

[0025] A motor M serving as a power source for propelling the vehicle 1 is disposed at a position on the exterior side of the accommodation compartment S2 with respect to the rear wall portion 27.

[0026] According to such a front trunk structure 100, the sound generated by the motor M can be effectively absorbed in the accommodation chamber S2.

[0027] <Embodiment 2> Next, a second embodiment of the present disclosure will be described with reference to Fig. 4. In this embodiment, the same components as those in the above embodiment are designated by the same reference numerals, and redundant descriptions of the structure, operation, and effects will be omitted.

[0028] The recess 220 of the front trunk structure 200 has a protrusion 223 disposed on an edge 222 on the interior side of the storage chamber S2 at the hole 30. The protrusion 223 protrudes upward from a surface 221A1 of a left end 221A of the bottom wall portion 221.

[0029] According to such a front trunk structure 200, luggage stored in the storage compartment S2 can be caught by the protrusion 223, so that the luggage can be prevented from falling into the hole 30.

[0030] The recess 220 also includes a hollow portion 40 having a hollow interior. The hollow portion 40 includes a hollow main body portion 41 extending in the vertical direction, a first opening 42 that is an upper end portion of the hollow main body portion 41 and opens to the interior side of the storage chamber S2, and a second opening 43 that is a lower end portion of the hollow main body portion 41 and opens downward and is connected to the inner opening 32 of the hole portion 30. The position of the hollow portion 40 is fixed by abutting against the protrusion 223.

[0031] According to such a front trunk structure 200, tools and the like can be stored inside the hollow portion 40. For example, a jack can be stored inside the hollow portion 40, and the hollow portion 40 can be used as a jack case (tool case). In addition, by appropriately changing the vertical length and size of the hollow portion 40, the frequency of sound that can be absorbed by the storage chamber S2 can be changed. In order to promote drainage from the hole portion 30, a drainage channel that avoids the protrusions 223 and the hollow portion 40 or that penetrates them may be provided on the surface of the bottom wall portion 221.

[0032] <Embodiment 3> Next, a third embodiment of the present disclosure will be described with reference to Fig. 5. In this embodiment, the same components as those in the above embodiment are designated by the same reference numerals, and redundant descriptions of the structure, operation, and effects will be omitted.

[0033] In the front trunk structure 300, the recess 320 has a hollow portion 340 that is hollow inside and extends in the vehicle width direction. The hollow portion 340 has a first opening 342 that is at the right end of the hollow portion 340 and opens to the interior side of the accommodation chamber S2, a second opening 343 that is at the lower left end of the hollow portion 340 and opens downward and connects to the inner opening 32 of the hole portion 30, and an expandable portion 341 that is arranged between the first opening 342 and the second opening 343 and can expand and contract in the vehicle width direction. The expandable portion 341 is a bellows-shaped tube portion. Note that the shape of the cross section of the expandable portion 341 in the radial direction (the front-rear direction in FIG. 5: the direction toward the rear of the paper) is not limited, and may have a cross section of, for example, a square shape, a circular shape, an irregular shape, or the like.

[0034] According to such front trunk structure 100, by expanding and contracting expansion section 341, the frequency of sound that can be absorbed in storage room S2 can be easily changed.

[0035] <Embodiment 4> Next, a fourth embodiment of the present disclosure will be described with reference to Fig. 6. In this embodiment, the same components as those in the above embodiment are designated by the same reference numerals, and redundant descriptions of the structure, operation, and effects will be omitted.

[0036] In the front trunk structure 400, the recess 420 includes a bottom wall 421, two side walls 424R and 424L rising from both ends of the bottom wall 421 in the width direction, and a rear wall 427 rising from the rear end of the bottom wall 421. The left side wall 424L is longer in the up-down direction than the right side wall 424R. The lower end 427A of the rear wall 427 includes a corner 427A1 at its left end. The corner 427A1 forms the lower left corner of the rear wall 427 and is connected to the lower end 424L1 of the left side wall 424L and the left end 421A of the bottom wall 421. The corner 427A1 is provided with a hole 430 formed to penetrate in the front-rear direction (the direction between the inside and outside of the storage room S2). The hole 430 is semicircular when viewed from the front. The bottom wall portion 421 is inclined downward as it goes leftward (toward the hole portion 430).

[0037] According to such a front trunk structure 100, since the hole 430 is provided in the rear wall 427, for example, the storage chamber S2 can effectively absorb sound generated from a member arranged on the outside of the storage chamber of the rear wall 427. Moreover, since the hole 430 is provided in the corner 427A1 of the lower end 427A of the rear wall 427, even if water enters the storage chamber S2, it can be drained to the outside of the storage chamber S2 through the hole 430. Furthermore, since the bottom wall 421 is inclined downward toward the hole 430, the drainage from the hole 430 can be improved.

[0038] <Other embodiments> The present disclosure is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included within the technical scope of the present disclosure. Furthermore, in addition to the embodiments described below, various modifications can be made without departing from the spirit of the present disclosure.

[0039] (1) In addition to the above embodiment, the position and shape of the hole can be changed as appropriate. For example, the hole may be disposed at the lower end of the side wall. In this case, for example, the storage chamber S2 can effectively absorb sound generated by the rotation of the tire T. The hole may also be provided at the connection (boundary) between the bottom wall and the side wall, or the connection (boundary) between the bottom wall and the rear wall. The shape of the hole may be a square, a rectangle, a triangle, an irregular shape, or the like.

[0040] (2) The skin attached to the surface of each wall of the recess may be attached in a manner that covers the opening of the hole. In this case, at least the part of the skin attached to the opening of the hole may be made of a material that is air- and water-permeable (e.g., a mesh material). This prevents baggage from falling into the hole while allowing the storage section to function as a resonator.

[0041] (3) A sound-producing body other than the motor may be disposed in the space outside the accommodation chamber. Examples of such a sound-producing body include various sound-producing components such as an engine and an air-conditioning compressor.

[0042] (4) The configuration of the vehicle is not particularly limited. The vehicle may have an engine as a power source, or may not have a motor. In addition, such a power source may be disposed in the center or rear of the vehicle.

[0043] (5) The front trunk structure exemplified in the above embodiment is not limited to use in vehicles, and may be provided in various vehicles. For example, the front trunk structure can be applied to vehicles such as trains and recreational vehicles as ground vehicles, airplanes and helicopters as flying vehicles, and ships and submarines as marine and underwater vehicles.
