The structure includes a deflection plate standing upright between a pair of seats on the rear side of the seats, and a light source provided on the lower front side of the deflection plate. When it is assumed that an imaginary straight line connecting between the light source and a reflection surface of the deflection plate is a first imaginary line, an imaginary straight line connecting between a middle portion of a rear view mirror and the reflection surface of the deflection plate is a second imaginary line, and an imaginary straight line orthogonal to the reflection surface of the deflection plate is a reference imaginary line, the reflection surface of the deflection plate is inclined at a predetermined angle in such a manner that the angle defined by the reference imaginary line and the first imaginary line, and the angle defined by the reference imaginary line and the second imaginary line are different from each other in a side view.

Description

TECHNICAL FIELD

The present invention relates to a rear structure of a vehicle including an openable rear window, for instance, wherein the vehicle rear structure is provided with a deflection plate configured to deflect turbulent air flowing into a vehicle compartment from the rear side of a seat when the rear window is opened.

BACKGROUND ART

In a so-called convertible vehicle, i.e., a vehicle including an openable roof on a top portion of a vehicle compartment portion where a passenger is seated, traveling air from the vehicle front side flows rearwardly of the vehicle along a surface of a vehicle body in a state that the openable roof is closed (a closed state).

On the other hand, in a state (an opened state) that the openable roof is opened, traveling air is less likely to stably flow rearwardly due to an opening formed in the top portion of the vehicle. Further, the vehicle compartment becomes a negative pressure state, as compared with the outside of the vehicle. Therefore, a flow of traveling air flowing through the top portion of the vehicle is likely to change, as compared with a state that the openable roof is closed.

For instance, it is known that in a state that an openable roof is opened, a part of traveling air flowing rearwardly of a seat over a front window changes its direction in such a manner that air is caused to flow back forwardly due to a negative pressure of a vehicle compartment (so-called turbulent air).

Therefore, in a state that an openable roof is opened, a passenger may feel annoyed with wind that impinges on the passenger due to turbulent air flowing into a vehicle compartment, whose direction is changed from air flowing rearwardly of a vehicle to air flowing forwardly of the vehicle, or noise caused by the wind.

In view of the above, various techniques are proposed to avoid wind in a state that an openable roof is opened, or noise caused by the wind.

For instance, in Patent Literature 1, there is provided a deflector device between, a pair of left and right seats and on the vehicle rear side of the seats in order to deflect turbulent air flowing into a vehicle compartment from the rear side of the seats in a state that an openable roof is opened. Further, the deflector device disclosed in Patent Literature 1 includes a deflection plate (a deflector plate) made of synthetic resin having transparency. Thus, in Patent Literature 1, the deflection plate is made transparent, and enhanced rear visibility is secured.

A rear view mirror configured to allow a passenger to see a rear area of a seat is disposed on the upper front side of a deflection plate. As a result, when the passenger sees the rear area through the rear view mirror, the passenger may also see the deflection plate disposed between the seats through the rear view mirror.

Nowadays, it is often the case that various switches such as an operation switch configured to allow a passenger to operate a navigation device, or an operation switch configured to allow a passenger to switch the suspension mode are disposed on a center console located on the lower front side of a deflection plate. A light source configured to emit light in association with turning on of a side marker lamp may be disposed in the switch.

In view of the above, in a case where a deflection plate made of a material having light reflectivity such as resin having transparency is provided as a deflection plate, illumination light emitted from a light source in a switch may be reflected by the deflection plate, and may be reflected on the rear view minor.

Specifically, in a vehicle provided with a deflection plate, illumination light from a switch may be reflected on a rear view mirror. This may obstruct a passenger from seeing a rear area through the rear view mirror.

SUMMARY OF INVENTION

In view of the aforementioned inconveniences, an object of the present invention is to provide a vehicle rear structure, which enables to avoid lowering of rear visibility due to reflection light reflected by a deflection plate.

In order to solve the aforementioned inconveniences, the present invention is directed to a rear structure of a vehicle provided with a pair of left and right seats disposed in a vehicle compartment, a roof configured to cover an upper portion of the vehicle compartment, and a rear window located on a vehicle rear side of the roof, the vehicle rear structure being capable of accommodating at least one of the roof and the rear window in a vehicle body. The vehicle rear structure includes a deflection plate standing upright between the paired seats and on a rear side of the seats; and a light source provided on a lower front side of the deflection plate. The deflection plate includes a reflection surface configured to reflect light forwardly. When it is assumed that an imaginary straight line connecting between the light source and the reflection surface of the deflection plate is a first imaginary line, an imaginary straight line connecting between a middle portion of a rear view mirror provided on an upper front side of the deflection plate, and the reflection surface of the deflection plate is a second imaginary line, and an imaginary straight line orthogonal to the reflection surface of the deflection plate is a reference imaginary line, the reflection surface of the deflection plate is an inclined surface inclined at a predetermined angle in such a manner that an angle defined by the reference imaginary line and the first imaginary line, and an angle defined by the reference imaginary line and the second imaginary line are different from each other in a side view.

As illustrated in FIG. 3, two screw holes (not illustrated) engageable with the fastening bolts 36 configured to engage the housing extension portion 35 of the roof link drive portion 31 are formed in the pillar core member 181.

In the vehicle 1 provided with the cover open/close mechanisms 20 and the roof open/close mechanisms 30 having the aforementioned configuration, the deck cover 13 is moved in such a manner as to open the accommodation portion S, and the openable roof 6 and the rear window 14 are collapsibly folded in the aforementioned state, and are accommodated in the accommodation portion S.

Specifically, in response to an operation of an unillustrated operation switch configured to designate accommodation of the openable roof 6 and the rear window 14, the cover link drive portion 23 of the cover open/close mechanism 20 pivotally moves the front cover link member 21 rearwardly and upwardly. Further, following the pivotal movement of the front cover link member 21, the rear cover link member 22 is pivotally moved in the same direction as the front cover link member 21. Thus, the deck cover 13 is moved upwardly and rearwardly while maintaining a posture thereof that a lower surface of the deck cover 13 is aligned with a substantially horizontal direction to open the accommodation portion S.

After the deck cover 13 starts moving as described above, the roof link drive portion 31 of the roof open/close mechanism 30 pivotally moves the first roof link 32 rearwardly, and the second roof link 33 and the third roof link are pivotally moved in respective predetermined detections in association with the pivotal movement of the first roof link 32.

Accompanied by pivotal movement of the links as described above, the rear roof 6b is pivotally moved downwardly and forwardly by about 180 degrees, and is shifted to a posture that a lower surface of the rear roof 6b faces a lower surface of the front roof 6a in the up-down direction. Further, the rear window 14 is pivotally moved until a posture that a front surface of the rear window 14 faces upwardly, and is moved to the lower side of the rear roof 6b after pivotal movement (after being folded). The front roof 6a, the rear roof 6b, and the rear window 14 stacked one over another in this order from the upper side are moved further rearwardly and downwardly, and are accommodated in the accommodation portion S.

In this way, the roof open/close mechanisms 30 move the openable roof 6 and the rear window 14 into the accommodation portion S, while folding the openable roof 6 and the rear window 14.

More specifically, the outer air receiving portion 521 is supported to the lower support portion 51 in a posture that the outer air receiving portion 521 intersects a vertical line at an angle θ1 of forward inclination at which a lower end thereof is located slightly on the rear side than an upper end thereof.

As illustrated in FIG. 6, the middle air receiving portion 522 is formed into a substantially rectangular shape with a long length in the vehicle width direction in a front view. More specifically, the middle air receiving portion 522 is formed into a substantially inverted trapezoidal shape in a front view, whose length of the lower side is shorter than the length of the upper side, to be in conformity with the shape of the outer air receiving portion 521 that the inner lateral edge thereof in the vehicle width direction is inclined in a front view. The length of the upper side and of the lower side of the middle air receiving portion 522 in the vehicle width direction is set longer than the length of those of the outer air receiving portion 521. AD outer lateral edge of the middle air receiving portion 522 in the vehicle width direction, in other words, a boundary between the middle air receiving portion 522, and the outer air receiving portion 521 is inclined in such a manner that the boundary is substantially in parallel to an inner lateral edge of the seatback bar 61 in the vehicle width direction.

As illustrated in FIG. 6 and FIG. 7 (particularly, in FIG. 7), the middle air receiving portion 522 includes a recess portion 522a formed into a shallow V-shape, which is convex rearwardly in a sectional view. The recess portion 522a is formed in such a manner that the amount of projection thereof increases as the recess portion 522a extends rearwardly from an upper end of the middle air receiving portion 522 toward downwardly. The amount of projection is maximum at a lower position (a position indicated by the symbol Q in FIG. 7) with respect to a middle position of the middle air receiving portion 522 in the up-down direction. Note that a front surface of the recess portion 522a corresponds to a “reflection surface” in the claims.

Thus, the middle air receiving portion 522, specifically, an upper area of the recess portion 522a with respect to the maximum projecting position Q is inclined forwardly in such a manner that the upper area intersects a vertical line at the angle θ2 of forward inclination, which is larger than the angle θ1 of forward inclination of the outer air receiving portion 521. The angle θ2 of forward inclination corresponds to a “predetermined angle” in the claims.

A configuration relating to the recess portion 522a of the middle air receiving portion 522 is described in detail.

As illustrated in FIG. 5 and FIG. 9, a rear view mirror 70 is mounted on an upper portion of an inner surface of the front glass 16a. The rear view mirror 70 is located on the upper front side of the rear deflector 50, and is disposed to face the rear deflector 50 in the front-rear direction in a plan view. Note that the rear view mirror 70 is disposed in such a manner that a mirror portion thereof is inclined slightly downwardly according to a seating position of a passenger.

As illustrated in FIG. 9, a center console 80 extending in the front-rear direction is disposed between the paired left and right seats 15.

Switches such as a rotary switch or a pressing switch projecting upwardly from an upper surface of the center console 80 are disposed on the center console 80. The switches are located on the lower front side of the recess portion 522a of the rear deflector 50. Although a specific purpose of use of the switches is not specifically limited, examples of the switches are an operation switch configured to allow a passenger to operate a navigation device, an operation switch configured to allow a passenger to switch the suspension mode, and an operation switch configured to allow a passenger to operate a vehicle information display device configured to display various vehicle information.

A light source 81 configured to emit illumination light spreading radially in association with turning on of a side marker lamp or the like is internally provided in the switch. The light source 81 is mounted in a posture that an upper surface thereof faces straight upwardly, or in a slightly inclined posture that an upper surface thereof faces forwardly and upwardly.

As illustrated in FIG. 9, it is assumed that an imaginary straight line connecting between a front surface of an upper portion of the recess portion 522a and the light source 81 in a side view, in other words, an imaginary straight line indicating a locus of illumination light to be emitted toward a front surface of an upper portion of the recess portion 522a in a side view is a first imaginary line VL1.

Further, it is assumed that an imaginary straight line connecting between the front surface of the upper portion of the recess portion 522a and a middle portion of the rear view mirror 70 in a side view is a second imaginary line VL2, and an imaginary straight line orthogonal to the front surface of the recess portion 522a in a side view is a reference imaginary line VL3.

The recess portion 522a of the rear deflector 50 (more specifically, an upper area with respect to the rearwardly maximum projecting position Q) is inclined forwardly to attain the angle θ2 of inclination with respect to a vertical line. The angle θ2 of forward inclination of the recess portion 522a is set to be an angle satisfying a condition that an angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 is smaller than an angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1.

FIG. 10 is an explanatory diagram illustrating a manner of reflection of illumination light emitted from the light source 81 onto the rear deflector 50.

When a side marker lamp is turned on by a passenger's operation, the light source 81 is turned on in association with the side marker lamp. As illustrated in FIG. 10, the light source 81 in an ON state emits illumination light L1 in such a manner as to spread in multiple directions.

Illumination light L1 from the light source 81 is incident on a front surface of an upper portion of the recess portion 522a of the rear deflector 50 at an incident angle, which is substantially equal to the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1. Further, illumination light L1 incident on the front surface of the upper portion of the recess portion 522a is reflected at a reflection angle, which is substantially equal to the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1, and is output as reflection light L2 from the recess portion 522a.

In this case, the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 is smaller than the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1. Therefore, reflection light L2 reflected by the recess portion 522a is output from the recess portion 522a at a reflection angle larger than the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 (in other words, at a reflection angle substantially equal to the angle θ3). Therefore, reflection light L2 reflected by the recess portion 522a reaches an upper portion with respect to a middle portion of the rear view mirror 70 through an area on the upper side with respect to the second imaginary line VL2.

Reflection light L2 that reaches an upper portion with respect to a middle portion of the rear view mirror 70 is reflected by an upper portion of a mirror surface of the rear view mirror 70. In this case, the rear view mirror 70 is inclined in such a manner that a mirror surface thereof faces slightly downwardly. Therefore, reflection light L2 from the recess portion 522a is incident on the rear view mirror 70 at a small incident angle from the upper side with respect to an imaginary line (not illustrated) orthogonal to the mirror surface of the rear view mirror 70. According to this configuration, reflection light L2 incident on the rear view mirror 70 is reflected at a small reflection angle, which is substantially equal to the incident angle, and is directed toward the forehead of a passenger seated on the lower rear side of the rear view mirror 70.

There is described a flow of traveling air in the vehicle 1 provided with the rear deflector 50 having the aforementioned configuration, in other words, a flow of traveling air X flowing rearwardly of the vehicle over the seats 15 from the front window 16, using FIG. 11 and FIG. 12.

Note that FIG. 11 is a diagram illustrating a flow of traveling air X in a side view, and FIG. 12 is a diagram illustrating a flow of traveling air X when viewed from the vehicle rear side.

When the vehicle 1 is traveling in a state that the openable roof 6 and the rear window 14 are accommodated, as illustrated in FIG. 11, traveling air X from the vehicle front side flows rearwardly and upwardly along the front window 16, and reaches the front deflector devices 40. Traveling air X passing through the front deflector devices 40 further flows rearwardly while passing through an area high over the seats 15, and reaches the cover header portion 133 of the deck cover 13.

A part of traveling air X that reaches the cover header portion 133 has its direction changed in such a manner that air is caused to flow back forwardly from the vehicle rear side by a negative pressure of the vehicle compartment, and flows into the vehicle compartment through the rear window opening 134. In the following, a part of traveling air, whose direction is changed from air flowing rearwardly of the vehicle to air flowing back forwardly of the vehicle, is referred to as turbulent air W (see FIG. 11).

As illustrated in FIG. 12, a part of turbulent air W flowing into the vehicle compartment through the rear window opening 134 flows further forwardly through the flowing space 523 formed between the paired left and right outer air receiving portions 521. On the other hand, turbulent air W that impinges on the rear deflector 50 has its direction changed by the outer air receiving portions 521, for instance, and flows outwardly in the vehicle width direction.

In other words, turbulent air W flowing into the vehicle compartment through the rear window opening 134 is separated into turbulent air W1 flowing forwardly through the flowing space 523, and turbulent air W2 flowing outwardly in the vehicle width direction by the rear deflector 50.

According to the rear structure of the vehicle 1 described as above, it is possible to avoid lowering of rear visibility due to reflection light L2 reflected by the rear deflector body 52.

Specifically, when light is emitted from the light source 81, illumination light L1 is incident on the recess portion 522a of the rear deflector body 52 along the first imaginary line VL1 connecting between a front surface of the recess portion 522a, and the light source 81. Assuming that the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1 is an incident angle, illumination light L1 incident on the recess portion 522a is reflected at a reflection angle, which is substantially equal to the incident angle (θ3).

In this case, the angle θ4 defined by the second imaginary line VL2 connecting between a front surface of the recess portion 522a and a middle portion of the rear view mirror 70, and the reference imaginary line VL3 is made different from the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1. Therefore, reflection light L2 reflected by a front surface of the recess portion 522a as described above, in other words, light reflected at a reflection angle, which is substantially equal to the incident angle (the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1) is output from the front surface of the recess portion 522a in a direction different from the direction of the second imaginary line VL2, and reaches a portion other than the middle portion of the rear view mirror 70. According to this configuration, it is possible to avoid light emitted from the light source 81 and reflected by the rear deflector body 52 from reaching a middle portion of the rear view mirror 70, in other words, it is possible to avoid illumination light L1 from the light source 81 from being reflected on a middle portion of the rear view mirror 70.

In this example, a middle portion of the rear view mirror 70 is a portion, which is likely to be in the field of vision of a passenger even in a case where the passenger sees an end of the rear view mirror 70 in the vehicle width direction, and is a portion where the amount of reflected information is large, as compared with both ends of the rear view mirror 70 in the vehicle width direction.

On the other hand, in the embodiment, it is possible to avoid illumination light L1 emitted from the light source 81 from being reflected on a middle portion of the rear view mirror 70. This is advantageous in suppressing lowering of rear visibility due to the light reflection.

In addition to the above, the rear view mirror 70 located on the upper side of the head of a passenger is adjusted to a posture such that the rear view mirror 70 is inclined slightly rearwardly and downwardly so that a middle portion of the rear view mirror 70 faces the vicinity of the eyes of the passenger. Therefore, reflection light L2 from the rear deflector body 52 located on the lower rear side of the rear view mirror 70 is incident on the rear view mirror 70 at a small incident angle, and then, is reflected rearwardly at a small reflection angle, which is substantially equal to the incident angle.

Therefore, in a case where reflection light L2 from the rear deflector body 52 is incident on a middle portion of the rear view mirror 70, light reflected by the rear view mirror 70 tends to be directed toward the vicinity of the eyes of a passenger, which may dazzle the passenger.

On the other hand, in the embodiment, reflection light L2 from the rear deflector body 52 is not directed to a middle portion of the rear view mirror 70, but is directed to an upper portion of the rear view mirror 70. Therefore, it is possible to avoid light reflected by the rear view mirror 70 from reaching in the vicinity of the eyes of a passenger. Thus, even in a case where reflection light L2 is reflected by the rear view mirror 70, it is possible to avoid that the reflection light may dazzle a passenger.

As described above, according to the embodiment, it is possible to avoid illumination light L1 from the light source 81 from being reflected on a middle portion of the rear view mirror 70, despite that the light source 81 is provided in a switch on the center console 80. This makes it possible to avoid that light reflection may dazzle a passenger (avoid light reflected by the rear view mirror 70 from reaching in the vicinity of the eyes of a passenger).

Further, in the embodiment, the rear deflector body 52 is formed in such a manner that the angle θ2 of forward inclination of the middle air receiving portion 522 with respect to a vertical line, and the angle θ1 of forward inclination of the outer air receiving portion 521 with respect to a vertical line are made different from each other. This makes it possible to avoid reflection of illumination light L1 on the rear view mirror 70, without impairing the function of the rear deflector body 52 configured to deflect turbulent air W from the vehicle rear side.

Specifically, it is necessary to form a back surface of the rear deflector body 52 as an inclined surface inclined with respect to a vertical line in order to deflect turbulent air W from the vehicle rear side in an intended direction.

However, an angle of inclination of the rear deflector body 52, which is necessary to make the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1, and the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 different from each other, in other words, the angle θ2 of forward inclination may not always coincide with an angle of inclination necessary for sufficiently exhibiting a deflection mechanism. Therefore, in a case where a rear deflector body is formed into a uniformly flat plate shape, and the angle of inclination of the rear deflector body is set to the aforementioned angle θ2 of forward inclination, it may be impossible to deflect turbulent air W from the vehicle rear side in an intended direction.

On the other hand, according to the embodiment, in which there is prepared the rear deflector body 52 integrally including the recess portion 522a and the outer air receiving portion 521, whose angles of inclination with respect to a vertical line are different front each other, it is possible to appropriately set the angle of inclination of the recess portion 522a in such a manner that the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1, and the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 are different from each other, while disposing the outer air receiving portion 521 at an angle suitable for deflecting turbulent air W from the vehicle rear side. This makes it possible to avoid reflection of illumination light L1 on the rear view mirror 70, without impairing the function of deflecting turbulent air W from the vehicle rear side.

Further, in the embodiment, it is possible to enhance comfort of a passenger, because the rear deflector body 52 integrally includes the middle air receiving portion 522 disposed in an area including a middle portion of the rear deflector body 52 in the vehicle width direction, and the paired left and right outer air receiving portions 521 disposed on the outer sides of the middle air receiving portion 522 in the vehicle width direction.

Specifically, in a case where the middle air receiving portion 522 is disposed at a middle position of the vehicle in the vehicle width direction, the middle air receiving portion 522 and the rear view mirror 70 face each other in the front-rear direction in a plan view, and the middle air receiving potion 522 is likely to receive illumination light Li from the light source 81. This may cause light emitted from the light source 81 and reflected by the middle air receiving portion 522 (a front surface of the recess portion 522a) to reach the rear view mirror 70.

However, the front surface of the recess portion 522a is inclined at the angle θ2 of forward inclination in such a manner that the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line V1, and the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 are different from each other. This makes it possible to avoid illumination light L1 from the light source 81 from being reflected on the rear view mirror 70. Therefore, even in a case where the middle air receiving portion 522 is disposed at a middle position of the vehicle in the vehicle width direction, it is possible to securely avoid lowering of rear visibility due to reflection of illumination light L1.

On the other hand, turbulent air W from the vehicle rear side tends to pass through the outside of the middle air receiving portion 522 in the vehicle width direction, and to flow toward the vicinity of the head of a passenger. In the embodiment, however, the outer air receiving portions 521 are disposed on the outer sides of the middle air receiving portion 522 in the vehicle width direction. Therefore, turbulent air W flowing toward the vicinity of the head of a passenger is deflected outwardly in the vehicle width direction by the outer air receiving portions 521. Thus, it is possible to securely avoid impingement of turbulent air W from the vehicle rear side on a passenger, particularly, wind around the ears of a passenger, and noise generated by the wind.

As described above, according to the embodiment, it is possible to avoid reflection of illumination light L1 on the rear view mirror 70, and impingement of turbulent air W, which annoy a passenger. Therefore, it is possible to enhance comfort of the passenger.

Further, an outer lateral edge of the middle air receiving portion 522 in the vehicle width direction is formed to be substantially parallel to an inner lateral edge of the seatback bar 61 in the vehicle width direction in a rear view. Therefore, it is possible to enhance design characteristics of the rear deflector body 52 in a rear view, while avoiding reflection of illumination light L1 on the rear view mirror 70.

Specifically, a lateral edge of the middle air receiving portion 522 is formed to be substantially parallel to a lateral edge of the seatback, bar 61. Therefore, it is possible to form a boundary between the middle air receiving portion 522 and the outer air receiving portion 521 into a shape in conformity with the shape of the seatback bar 61, and to enhance the appearance of a vehicle rear portion including the rear deflector body 52 and the seatback bar 61.

For instance, it is possible to make the external appearance of the rear deflector body 52, which is viewed through the rear window opening 134 in a state that the rear window 14 is accommodated in the accommodation portion S, fit the seatback bar 61, and to enhance the appearance of a vehicle rear portion.

Further, in the embodiment, the rear deflector body 52 is made of acrylic resin having transparency. Therefore, it is possible to sufficiently secure rear visibility through the rear deflector body 52. This means that it is possible to secure enhanced rear visibility, in combination with the aforementioned measures for avoiding light emitted from the light source 81 and reflected by the rear deflector body 52 from reaching a middle portion of the rear view mirror 70.

Further, in the embodiment, the light source 81 is disposed in a posture that an upper surface thereof faces straight upwardly, or in a slightly inclined posture that an upper surface thereof faces forwardly and upwardly. Therefore, as compared with brightness of illumination light Li incident on an upper portion of the recess portion 522a of the rear deflector body 52, brightness of illumination light L1 incident on a lower portion of the recess portion 522a is reduced.

Therefore, even in a case where illumination light Li incident on a lower portion of the recess portion 522a is reflected toward a middle portion of the rear view mirror 70, it is possible to suppress brightness of reflection light L2 that reaches the middle portion of the rear view mirror 70. This makes it possible to avoid lowering of rear visibility due to reflection of illumination light L1 on the rear view mirror 70.

As described above, a preferred embodiment of the present invention is described. The present invention, however, is not limited to a configuration of the embodiment, but may be modified in various ways as far as the modifications do not depart from the gist of the present invention.

For instance, in the embodiment, the openable roof 6 (a roof) is a hard-top openable roof configured to be accommodated in a vehicle body in a folded state. The embodiment, however, is not limited to the above. The openable roof may be an openable roof to be accommodated in a vehicle body in a dismounted state, or a soft-top openable roof constituted by hood cloth and a hood bone.

Further, the vehicle 1 of the embodiment is a convertible vehicle, in which the openable roof 6 and the rear window 14 are accommodated in a vehicle body. Various alternatives are proposed, however, as far as at least a part of members constituting an upper portion and a rear portion of a vehicle compartment is accommodated in a vehicle. For instance, a vehicle configured to accommodate only a roof constituting an upper portion of a vehicle compartment, or a vehicle configured to accommodate only a rear window may be employed.

Further, in the embodiment, the rear deflector body 52 (a deflection plate) is a colorless and transparent member made of acrylic resin. The embodiment, however, is not limited to the above. For instance, a rear deflector body including a glossy front surface may be used.

Further, in the embodiment, the angle θ2 of forward inclination of the recess portion 522a is set in such a manner that the angle θ4 defined by the reference imaginary line VL3 and the second imaginary line VL2 is smaller than the angle θ3 defined by the reference imaginary line VL3 and the first imaginary line VL1. The embodiment, however, is not limited to the above. The angle θ2 of forward inclination of the recess portion 522a may be set in such a manner that the angle θ4 with respect to the second imaginary line VL2 is larger than the angle θ3 with respect to the first imaginary line VL1.

<Summary of Embodiment>

The following is a summary of the embodiment.

The embodiment relates to a rear structure of a vehicle provided with a pair of left and right seats disposed in a vehicle compartment, a roof configured to cover an upper portion of the vehicle compartment, and a rear window located on a vehicle rear side of the roof, the vehicle rear structure being capable of accommodating at least one of the roof and the rear window in a vehicle body. The vehicle rear structure includes a deflection plate standing upright between the paired seats and on a rear side of the seats; and a light source provided on a lower front side of the deflection plate. The deflection plate includes a reflection surface configured to reflect light forwardly. When it is assumed that an imaginary straight line connecting between the light source and the reflection surface of the deflection plate is a first imaginary line, an imaginary straight line connecting between a middle portion of a rear view mirror provided on an upper front side of the deflection plate, and the reflection surface of the deflection plate is a second imaginary line, and an imaginary straight line orthogonal to the reflection surface of the deflection plate is a reference imaginary line, the reflection surface of the deflection plate is an inclined surface inclined at a predetermined angle in such a manner that an angle defined by the reference imaginary line and the first imaginary line, and an angle defined by the reference imaginary line and the second imaginary line are different from each other in a side view.

The roof may be an openable roof to be accommodated in a vehicle body in a folded state, or may be an openable roof to be accommodated in a vehicle body in a dismounted state. Further, the roof may be a soft-top openable roof constituted by hood cloth and a hood bone, or may be a hard-top openable roof including a metal roof panel.

The deflection plate may be a deflection plate made of synthetic resin having transparency, for instance, or may be a deflection plate having a glossy front surface.

The light source may be a light source such as an LED, which is incorporated in various switches such as an operation switch configured to allow a passenger to operate a navigation device, or a changeover switch configured to allow a passenger to switch the suspension mode; or may be a light source mounted in a component other than a switch.

According to the vehicle rear structure, it is possible to avoid lowering of rear visibility due to reflection light reflected by a deflection plate.

Specifically, when light is emitted from the light source, illumination light is incident on the reflection surface of the deflection plate along the first imaginary line connecting between the reflection surface and the light source. Assuming that the angle defined by the reference imaginary line and the first imaginary line is an incident angle, illumination light incident on the reflection surface is reflected at a reflection angle, which is substantially equal to the incident angle.

In this case, the angle defined by the second imaginary line connecting between the reflection surface and a middle portion of the rear view mirror, and the reference imaginary line is made different from the angle defined by the reference imaginary line and the first imaginary line. Therefore, reflection light reflected by the reflection surface as described above, namely, light reflected at a reflection angle, which is substantially equal to the incident angle (the angle defined by the reference imaginary line and the first imaginary line) is, output from the reflection surface in a direction different from the direction of the second imaginary line, and reaches a portion other than the middle portion of the rear view mirror. According to this configuration, it is possible to avoid light emitted from a light source and reflected by a deflection plate from reaching a middle portion of a rear view mirror, in other words, it is possible to avoid light emitted from a light source from being reflected on a middle portion of a rear view mirror.

Note that a middle portion of a rear view mirror is a portion, which is likely to be in the field of vision of a passenger even in a case where the passenger sees an end of the rear view mirror in the vehicle width direction, and is a portion where the amount of reflected information is large, as compared with both ends of the rear view mirror in the vehicle width direction.

On the other hand, in the vehicle rear structure, it is possible to avoid light emitted from a light source from being reflected on a middle portion of the rear view mirror. This is advantageous in suppressing lowering of rear visibility due to the light reflection.

In addition to the above, the rear view mirror located on the upper side of the head of a passenger is adjusted to a posture such that the rear view mirror is inclined rearwardly and downwardly so that a middle portion of the rear view minor faces the vicinity of the eyes of the passenger. Therefore, reflection light from the deflection plate located on the lower rear side of the rear view mirror is incident on the rear view mirror at a small incident angle, and then, is reflected rearwardly at a small reflection angle, which is substantially equal to the incident angle.

Therefore, in a case where reflection light from the deflection plate is incident on a middle portion of the rear view mirror, light reflected by the rear view mirror tends to be directed toward the vicinity of the eyes of a passenger, which may dazzle the passenger.

On the other hand, in the vehicle rear structure, reflection light from the deflection plate is directed to a portion other than the middle portion of the rear view mirror. Therefore, it is possible to avoid light reflected by the rear view mirror from reaching in the vicinity of the eyes of a passenger. For instance, in a case where reflection light from the deflection plate is incident on an upper portion of the rear view mirror, light reflected by the rear view mirror reaches an area (the forehead) above the eyes of a passenger. According to this configuration, even in a case where reflection light from the deflection plate is reflected by the rear view mirror, it is possible to avoid that the reflection light may dazzle a passenger.

As described above, according to the vehicle rear structure, it is possible to avoid light emitted from the light source from being reflected on a middle portion of the rear view mirror despite that the light source is disposed on the lower front side of the deflection plate. This makes it possible to avoid that light reflection may dazzle a passenger (avoid light reflected by the rear view mirror from reaching in the vicinity of the eyes of a passenger).

Preferably, the deflection plate may integrally include a substantially flat plate-shaped reflection portion having the reflection surface inclined at the predetermined angle, and a substantially flat plate-shaped air receiving portion configured to receive turbulent air flowing into the vehicle compartment from the vehicle rear side. An angle of inclination of the reflection portion with respect to a vertical line, and an angle of inclination of the air receiving portion with respect to a vertical line may be made different from each other in a side view.

According to the aforementioned configuration, it is possible to avoid reflection of illumination light on the rear view mirror, without impairing the function of the deflection plate configured to deflect turbulent air.

Specifically, it is necessary to form a back surface of the deflection plate as an inclined surface inclined with respect to a vertical line in order to deflect turbulent air from the vehicle rear side in an intended direction.

However, an angle of inclination of the deflection plate, which is necessary to make the angle defined by the reference imaginary line and the first imaginary line, and the angle defined by the reference imaginary line and the second imaginary line different from each other, in other words, a predetermined angle may not always coincide with an angle of inclination of the deflection plate necessary for sufficiently exhibiting a deflection function. Therefore, in a case where a deflection plate is formed into a uniformly flat plate shape, and the angle of inclination of the deflection plate is set to the aforementioned predetermined angle, it may be impossible to deflect turbulent air from the vehicle rear side in an intended direction.

On the other hand, in a case where there is prepared the deflection plate integrally including the reflection portion and the air receiving portion, whose angles of inclination with respect to a vertical line are different from each other, it is possible to appropriately set the angle of inclination of the reflection portion in such a manner that the angle defined by the reference imaginary line and the first imaginary line, and the angle defined by the reference imaginary line and the second imaginary line are different from each other, while disposing the air receiving portion at an angle of inclination suitable for deflecting turbulent air from the vehicle rear side. This makes it possible to avoid, reflection of illumination light on a rear view mirror, without impairing the function of deflecting turbulent air.

Preferably, the deflection plate may integrally include the reflection portion disposed in an area including a middle portion of the deflection plate in a vehicle width direction, and a pair of the left and right air receiving portions disposed on outer sides of the reflection portion in the vehicle width direction.

According to the aforementioned configuration, it is possible to enhance comfort of a passenger.

Specifically, in a case where the reflection portion of the deflection plate is disposed at a middle position of the vehicle in the vehicle width direction, the reflection portion and the rear view mirror face each other in the front-rear direction in a plan view, and the reflection portion is likely to receive light emitted from the light source. This may cause light emitted from the light source and reflected by the reflection portion (a reflection surface corresponding to a front surface of the reflection portion) to reach the rear view mirror.

However, the reflection surface is inclined at a predetermined angle in such a manner that the angle defined by the reference imaginary line and the first imaginary line, and the angle defined by the reference imaginary line and the second imaginary line are different from each other. This makes it possible to avoid light emitted from the light source from being reflected on the rear view mirror. Therefore, even in a case where the reflection portion is disposed at a middle position of the vehicle in the vehicle width direction, it is possible to securely avoid lowering of rear visibility due to reflection of illumination light.

Turbulent air from the vehicle rear side tends to pass through the outside of a reflection portion in the vehicle width direction, and to flow toward the vicinity of the head of a passenger. In the aforementioned configuration, however, an air receiving portion is disposed on the outside of a reflection portion in the vehicle width direction. Therefore, turbulent air flowing toward the vicinity of the head of a passenger is deflected outwardly in the vehicle width direction, for instance, by the air receiving portion. Thus, it is possible to securely avoid impingement of turbulent air on a passenger, and noise generated by the impingement.

As described above, according to the aforementioned configuration, it is possible to avoid reflection of illumination light on the rear view mirror, and impingement of turbulent air, which annoy a passenger. Therefore, it is possible to enhance comfort of the passenger.

Preferably, the vehicle rear structure may further include an adjacent member adjacent to the deflection plate in a vehicle width direction, and a part of an outer peripheral edge of the reflection portion may be formed to be substantially parallel to a part of an outer peripheral edge of the adjacent member in a rear view.

The adjacent member may be a seatback bar projecting upwardly on the rear side of a seat, for instance in a case where a rear window is accommodated in a vehicle body, the adjacent member may be a peripheral edge portion of a window opening, which remains after accommodation of the rear window.

A part of an outer peripheral edge of the reflection portion may be one of an upper edge portion, a lower edge portion, a left edge portion, and a right edge portion, or may be combination of these edge portions.

According to the aforementioned configuration, it is possible to enhance design characteristics of the deflection plate in a rear view, while avoiding reflection of illumination light on the rear view mirror.

Specifically, a part of an outer peripheral edge of the reflection portion is formed substantially parallel to a part of an outer peripheral edge of the adjacent member. Therefore, it is possible to form a boundary between the reflection portion and the air receiving portion into a shape in conformity with the shape of the adjacent member, and to enhance the appearance of a vehicle rear portion including the deflection plate and the adjacent member in a rear view.

For instance, in a case where the rear window is accommodated in a vehicle body, the external appearance of the deflection plate, which is viewed through the window opening in the accommodated state, fits an adjacent member. Thus, it is possible to enhance the appearance of a vehicle rear portion.

Preferably, the deflection plate may be made of synthetic resin having transparency.

According to the aforementioned configuration, it is possible to secure enhanced rear visibility.

Specifically, in a case where a deflection plate is made of synthetic resin having transparency, it is possible to sufficiently secure rear visibility through the deflection plate. A part of light emitted from a light source may be reflected by the deflection plate, and the reflection light may reach the rear view mirror, despite that the material of the deflection plate has transparency. However, according to the vehicle rear structure, in which the angle defined by the reference imaginary line and the first imaginary line, and the angle defined by the reference imaginary line and the second imaginary line are made different from each other, it is possible to avoid that light reflected by the rear view mirror may dazzle a passenger. Therefore, it is possible to secure enhanced rear visibility.

Note that in a case where the reflection surface of the deflection plate is a glossy surface, enhanced design characteristics of the deflection plate are expected. In this case, the amount of reflection on the deflection plate may increase. However, enhanced rear visibility is yet secured by the effect of avoiding that light dazzles a passenger by angle setting as described above.
