Description
Technical Field
The present invention relates to a speaker-mounted vehicle body structure including a vehicle body and a speaker.
Background
An acoustic device (so-called car audio) for listening and enjoying by an occupant is sometimes mounted on the car. Such an acoustic device includes a speaker that outputs sound. As is well known, a speaker has a cabinet (so-called Enclosure) and a speaker unit (speaker unit) provided in the cabinet and including a coil, a magnet, a drum paper (cone paper), and the like.
Recently, a technique of combining a woofer outputting a heavy bass with a main speaker to construct a speaker system has been widely used for improving acoustic performance. Since the volume of the cabinet constituting the woofer is large, a large space is required for mounting the woofer. Therefore, if the woofer is disposed in the passenger compartment, the space of the passenger compartment becomes narrow. In order to avoid this, the woofer is disposed at a position rearward of the rear seat, for example, in a luggage loading space (luggage compartment).
The weight of the woofer is also relatively large. Therefore, the portion of the vehicle body where the woofer is mounted is required to have sufficient supporting rigidity.
However, the rear seat in the automobile functions as a so-called buffer zone. Therefore, when the woofer is provided in the luggage compartment, the supporting rigidity of the luggage compartment is increased as described above, and as a result, the rigidity of the buffer zone (cushioning zone) is increased. In this case, there is a concern that kinetic energy generated by the collision is not easily relaxed (reduced) when the object collides with the rear portion of the vehicle body.
From this viewpoint, japanese patent laying-open No. 2010-125916 proposes a vehicle body rear structure in which a speaker bracket is provided between a rear wheel house and a rear pillar of a vehicle body of a passenger/cargo vehicle (wagon type), and a speaker unit of a woofer is supported by the speaker bracket.
Disclosure of Invention
The structure described in japanese patent laid-open publication No. 2010-125916 requires an opening for mounting a speaker unit to be formed in the inner wall of the trunk. However, since it is difficult for sales personnel or users to make such a portion open or mount the speaker unit, manufacturers have to perform these operations. Therefore, in the case where the user wishes to set the speaker unit, the opportunity is limited to purchasing a new car. In this case, too, a bass reflex port (bass reflex port) for improving sound quality cannot be formed.
In addition, even if the user wishes to select a speaker unit that matches his/her own preference, it is difficult to install the speaker unit in the opening if the diameter of the speaker unit is too small or too large as compared with the diameter of the opening. That is, the speaker unit that can be mounted on the opening is limited to only the speaker unit whose diameter is a size corresponding to the diameter of the opening.
The general object of the present invention is to provide a vehicle body structure with a speaker mounted thereon, which can select a speaker unit that a user likes even after purchasing an automobile, can be easily mounted, and can also realize an improvement in sound quality.
The main object of the present invention is to provide a vehicle body structure with a speaker, which can sufficiently mitigate kinetic energy even when an object collides with the rear part of the vehicle body.
According to one aspect of the present invention, there is provided a vehicle body structure for mounting a speaker, including a vehicle body constituting an automobile and the speaker mounted to the vehicle body, wherein the vehicle body has an attenuator mounting portion to which a vibration attenuator (vibration attenuator) for attenuating vibration from a traveling wheel (wheel) is mounted, the speaker has a case and a speaker unit, and the case is disposed at a position rearward in a vehicle body traveling direction than the attenuator mounting portion; the speaker unit is provided in the case, and is located below the attenuator mount in the vehicle body up-down direction.
According to the present invention, the damper mounting portion, which is a portion having high rigidity on the vehicle body side, and the speaker unit, which is a portion having high rigidity on the speaker side, are disposed so as to be able to be displaced from each other. Therefore, when an object (collided object) collides with the rear portion of the vehicle body, the case constituting the speaker is easily crushed. Therefore, the case can be prevented from moving significantly toward the front of the vehicle body while maintaining its shape, and the buffer can be sufficiently secured, so that the kinetic energy at the time of collision can be sufficiently relaxed.
Also in this case, the speaker is mounted on the vehicle body together with the cabinet. Therefore, it is not necessary to form an opening for mounting only the speaker unit on the vehicle body. Thus, after the user purchases and is delivered the car, the user can choose to install his/her favorite woofer. That is, the number of selection targets of the woofer increases, and in the case where the user himself/herself wishes to mount the woofer on the vehicle body, the desire can be satisfied.
The above objects, features and advantages will be easily understood from the following description of the embodiments with reference to the attached drawings.

Detailed Description
Hereinafter, a speaker-mounted vehicle body structure according to the present invention will be described in detail with reference to the drawings, by taking a preferred embodiment as an example. The following "front", "rear", "left", "right", "lower" and "upper" refer to the front, rear, left, right, lower, and upper sides of an occupant seated in the driver's seat unless otherwise specified. The front and rear of the vehicle (automobile 10) in the traveling direction are synonymous with the front and rear, respectively, and the vehicle width direction is synonymous with the left-right direction.
Fig. 1 is a schematic partial cross-sectional view of a car 10 with a car audio mounted therein, which is visually confirmed from the rear. The automobile 10 is a four-wheel automobile having a vehicle body 12 and front and rear wheels 14 and 16 as running wheels (wheels), wherein the front and rear wheels 14 and 16 are rotatably mounted on the vehicle body 12. In fig. 1, the front wheel 14 is positioned to overlap the rear wheel 16.
Rear dampers 17 as vibration dampers are provided on the left and right rear wheels 16, respectively. The rear damper 17 has a damper rod (damper rod) 19 exposed upward from the pipe 18 so as to be movable forward and backward, and a flange member 20 is provided near the upper end of the damper rod 19. The flange member 20 from the upper end of the tube 18 is covered with the bellows 21, and therefore, the damper rod 19 is shielded by the bellows 21.
On the other hand, the vehicle body 12 includes a floor panel 22, left and right side members 24, and left and right rear fenders 28 that constitute a tire cover (tire house) 26. As shown in fig. 2, an inner cover 29 of the rear fender 28 provided therein is exposed into the trunk 30, and a recess 32 recessed outward in the vehicle width direction is formed in an upper inner wall thereof. In accordance with this, a bulge (bulging portion) 34 that protrudes relatively outward in the vehicle width direction is formed below the concave portion 32 of the inner cover 29. The bulge 34 is roughly divided into a damper housing 36, a fuel pipe housing 38, and a tire cover 40.
Returning to fig. 1, the flange member 20 is connected to a top plate-like connecting portion 41 that defines the damper housing portion 36 via a connecting plate 42 by a bolt or nut, not shown. That is, the top plate-like connecting portion 41 is an attenuator attaching portion. As shown in fig. 3, through holes 43 and 44 are formed in the connecting plate 42 and the top plate-like connecting portion 41, respectively, and the portions of the damper rod 19 closer to the distal end than the flange member 20 pass through the through holes 43 and 44. Further, since the top plate-like connecting portion 41 is set to have a large area, and the connecting plate 42 and the reinforcing plate 46 are attached, it has higher rigidity than other portions. As a result, the rear damper 17 is connected to a portion (the top plate-like connecting portion 41) having higher rigidity than other portions. The damper housing portion 36 is provided with a cover member 48, and the top ends of the top plate-like connecting portion 41 and the damper rod 19 are covered with the cover member 48.
As shown in fig. 3, a fuel pipe 50 is provided in the fuel pipe housing 38. Cover member 52 is removably screwed into an opening at the upper end of fuel tube 50. The cover member 52 is unscrewed and removed by the oil supplier. Then, fuel such as gasoline or light oil is supplied from an oil supply pipe inserted into the upper end of fuel pipe 50. Thus, the opening at the upper end of fuel pipe 50 serves as an oil supply port. The supplied fuel is stored in a fuel tank, not shown, connected to the lower end of the fuel pipe 50 via the fuel pipe 50.
The fuel pipe housing portion 38 is provided in front of the damper housing portion 36 on the left. Thus, fuel tube 50 is positioned in front of left rear shock absorber 17. When visually confirmed from the rear of the vehicle body 12, the rear shock absorber 17 on the left overlaps the fuel pipe 50.
A woofer 60 (one type of speaker) constituting a speaker system of the car audio is supported by the left rear fender 28 through the inner cover 29. The woofer 60 is combined with a main speaker, not shown, and mainly outputs a heavy bass. The speaker-mounted vehicle body structure according to the present embodiment is employed to mount the woofer 60 on the vehicle body 12.
The woofer 60 will be schematically described. In addition, the "front surface" of the woofer 60 represents the surface on which the speaker unit 66 is provided, and the "rear surface" represents the rear surface thereof.
Fig. 4 and 5 are a front general perspective view and a rear general perspective view of the woofer 60, respectively. The woofer 60 has: a case 62 (so-called housing) as a hollow body; and a speaker unit 66 including a paper drum 64 supported by the casing 62 so as to be capable of vibrating with respect to the casing 62, a coil, not shown, and the like, disposed in the casing 62. A bass reflex port (bass reflex ports) 68 is formed in the case 62, and the bass reflex port 68 penetrates into the hollow interior of the case 62.
A small wing plate portion 72 and a large wing plate portion 74, each of which has a bolt insertion hole 70, are provided at the lower portion and the upper portion of the case 62. The bolt insertion holes 70 are also formed in the rear surface of the main body of the case 62. The bolt insertion holes 70 overlap with bolt fixing holes formed in the rear fender 28, the inner cover 29, and the like. The woofer 60 is supported by the vehicle body 12 by screwing nuts onto bolts, not shown, which are inserted into the bolt insertion holes 70 and the bolt fixing holes.
As shown in fig. 2, when the woofer 60 is supported by the vehicle body 12, the speaker unit 66 is located below and rearward of the rear end of the top plate-like coupling portion 41 (attenuator attaching portion). In a front view from the front of the vehicle body 12 or in a rear view from the rear, the woofer 60, the rear damper 17 on the left, and the fuel pipe 50 overlap (see fig. 1).
In addition, a front-surface-side fragile slit 76 is formed in the front surface of the main body of the case 62, and the front-surface-side fragile slit 76 extends from above the speaker unit 66 to above the main body of the case 62 and is slightly inclined toward the front of the vehicle body 12 as it goes away from the speaker unit 66. On the other hand, a rear-surface-side fragile slit 78a and a side-surface-side fragile slit 78b are formed on the rear surface and the side surface of the main body, respectively. The portions where these fragile slits 76, 78a, 78b are formed are fragile portions having lower rigidity than other portions of the case 62.
The car audio includes, in addition to the above-described woofer 60, a compact disk player, or a hard disk drive storing music, a main speaker, or the like. Although not shown, an optical disk player or a hard disk drive is disposed below the instrument panel for user operation.
The vehicle body structure with the speaker according to the present embodiment is basically configured as described above, and the operational effects thereof will be described next.
When the woofer 60 is mounted to the vehicle body 12, as described above, the small wing portion 72, the large wing portion 74, and the bolt insertion hole 70 formed in the rear surface of the main body of the case 62 are overlapped with the bolt fixing hole formed in the vehicle body 12 (the rear fender 28 and the like), and then the bolts are inserted into the bolt insertion hole 70 and the bolt fixing hole. Further, the woofer 60 is supported by the vehicle body 12 by screwing a nut onto the bolt.
As described above, in the present embodiment, the cabinet 62 of the woofer 60 is attached to the vehicle body 12. Therefore, it is not necessary to form an opening for mounting the speaker unit 66 on the inner wall of the trunk room 30. Thus, the user can select his own favorite woofer 60 after purchasing and delivering the automobile 10. That is, the selection object of the woofer 60 increases. Further, even when the user himself/herself desires to mount the woofer 60 on the vehicle body 12, the desire is easily satisfied.
The woofer 60 is supported on the side surface inner wall of the vehicle body 12 behind the tire cover 26 on the rear left side in a posture along the shape of the damper housing 36 that is a part of the bulge 34. In other words, the woofer 60 is disposed at a corner of the luggage compartment 30, specifically above the left inside surface. That is, the woofer 60 is not provided at a position interfering with the luggage such as the center of the luggage compartment 30. Accordingly, the degree of freedom in arrangement of the baggage in the trunk room 30 is increased, and therefore, the baggage can be easily stored in the trunk room 30. In short, the capacity of the luggage compartment 30 can be fully utilized.
The automobile 10 travels forward as the driver depresses the accelerator pedal. At this time, the user (driver or co-occupant) can play the musical composition using the optical disk player or the hard disk drive for appreciation. In this case, the middle-high tone of the musical composition is output from the main speaker, and the heavy-low tone is output from the woofer 60. In the present embodiment, since the bass reflex port 68 is formed in the cabinet 62 constituting the woofer 60, the user can listen to music with good sound quality.
During forward travel, backward travel, or the like, a situation may occur in which some object (collided object) collides with the rear of the vehicle 10. The rear portion of the vehicle body 12 is a buffer zone, and is relatively easily crushed in response to a collision. Accordingly, the passenger compartment is prevented from being crushed.
When the rear fender 28 or the like is crushed, the woofer 60 is sandwiched between the crashed object and the rear damper 17 on the left. Since the rigidity of the collision object and the rear shock absorber 17 is sufficiently large, a large load acts on the woofer 60. Here, the speaker unit 66 of the woofer 60 is located below the top plate-like coupling portion 41 (the damper mounting portion to which the rear damper 17 is coupled). That is, the ceiling-like coupling portion 41 having a high rigidity in the vehicle body 12 and the speaker unit 66 having a high rigidity in the woofer 60 relatively generate positional displacement. Therefore, the portion of the case 62 having relatively low rigidity is adjacent to the top plate-like connecting portion 41. Further, on the front surface of the upper portion of the case 62, as described above, the front-surface-side fragile slit 76 is formed, and the rear-surface-side fragile slit 78a and the side-surface-side fragile slit 78b are formed on the rear surface and the side surface of the case 62.
Therefore, when the collided object collides with the rear portion of the vehicle body 12, as shown in fig. 6, the upper portion of the case 62 sandwiched by the collided object and the rear shock absorber 17 is particularly liable to be crushed. Accordingly, the case 62 is prevented from moving significantly toward the front of the vehicle body 12 while maintaining its shape. The speaker unit 66 is pushed by the collision object and slightly moves forward of the vehicle body 12, but is stopped by being brought into contact with the damper housing portion 36 of the bulge portion 34 so as to overlap or be positioned below the top plate-like connecting portion 41 positioned forward and having high rigidity when visually confirmed from the front or rear of the vehicle body 12.
As is clear from this, according to the present embodiment, even when the woofer 60 is disposed in the trunk room 30 of the vehicle body 12 and the rigidity is improved by the ceiling-like connecting portion 41, the case 62 of the woofer 60 is easily crushed at the time of collision of the collided object. Therefore, the buffer can be sufficiently ensured. Accordingly, the kinetic energy at the time of collision of the collided object with the vehicle body 12 is sufficiently relaxed, so that the passenger compartment can be prevented from being crushed.
The case 62 is crushed, and the speaker unit 66 comes into contact with the top plate-like connecting portion 41 and stops. In this way, if the woofer 60, the rear damper 17, and the fuel pipe 50 are positioned so as to overlap each other, the rear damper 17 becomes a barrier of the woofer 60 when the buffer zone is crushed. Therefore, it is possible to avoid breakage of the fuel pipe 50 due to abutment of the case 62 and the speaker unit 66 against the fuel pipe 50.
As described above, according to the speaker-mounted vehicle body structure of the present embodiment, the favorite woofer 60 can be selectively mounted on the rear part of the vehicle body 12. In addition, even when an object collides with the rear portion of the vehicle body 12, a part of which has increased rigidity as the woofer 60 is attached, the rear portion effectively functions as a buffer area, so that the kinetic energy at the time of collision can be sufficiently relaxed.
The present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
For example, the speaker is not particularly limited to the woofer 60, and may be a main speaker, a subwoofer (subwoofer), or the like.
In this embodiment, the woofer 60 is disposed at the left rear part of the vehicle body 12, but may be disposed at the right rear part.
The vehicle 10 may be a fuel cell vehicle equipped with a fuel cell stack, or an electric vehicle equipped with a battery, that is, a vehicle not equipped with the fuel pipe 50. Further, the hybrid vehicle may be a so-called hybrid vehicle.
