Description

  The present invention relates to a vehicle body upper structure provided with a header panel to which an inner mirror is attached.

  A header panel is attached to a front end portion of a roof panel of an automobile in a cantilever state, and an inner mirror is attached to the header panel (for example, Patent Document 1).

JP, 2016-049836, A

  Even in the case where an electronic device is provided on the vehicle front side and the vehicle upper side in the vehicle interior such as near a windshield (front glass), it is desired that the mounting rigidity of the inner mirror be excellent.

  In recent years, for the purpose of alleviating collision damage and the like, electronic devices such as a camera for monitoring the front of a vehicle and a laser radar may be disposed at a position on the vehicle front side of a header panel near the upper end of a windshield. In this case, the mounting position of the inner mirror in the header panel is located rearward of the disposition position of the electronic device. As described above, since the header panel is mounted in a cantilever supported state with the vehicle front end as a fixed end and the vehicle rear end as a free end, when the mounting position of the inner mirror is closer to the vehicle rear, the vehicle rear end of the header panel As a result, the inner mirror also vibrates easily. The vibration of the inner mirror leads to the deterioration of the rear view. As described in Patent Document 1, if a reinforcing member having a size equivalent to that of the header panel is attached in the header panel, or a member in contact with the vehicle rear end of the header panel is attached to the roof panel, the mounting rigidity Can be increased to reduce the vibration of the inner mirror. However, this leads to an increase in the number of manufacturing processes and weight. It also leads to increased costs. Therefore, it is desirable that the mounting rigidity of the inner mirror can be improved while having a simple configuration.

  Furthermore, in the header panel, a part of the electric wire connected to the above-mentioned electronic device may be stored. In this case, it is also desirable to prevent water such as dew condensation water dropped from the roof panel into the header panel from flowing along the electric wire into the electronic device.

  Therefore, one of the objects of the present invention is to provide a vehicle body upper structure which has high mounting rigidity of the inner mirror and can also prevent water leakage to the electronic device side through the electric wire in the header panel.

The vehicle body upper structure according to one aspect of the present invention is
An upper structure of a vehicle body including a header panel to which an inner mirror is attached,
The header panel is
An apparatus area provided with a through hole through which an electric wire extending from an electronic apparatus disposed on the vehicle front side of the header panel is passed;
And a mounting area of the inner mirror located at the rear of the vehicle than the apparatus area,
The vehicle front end of the attachment area of the inner mirror has a step shape provided at a position lower than the vehicle rear end of the device area.

  The header panel provided in the above-described vehicle body upper structure is formed in a step shape in which the mounting region of the inner mirror on the vehicle rear side is lower than the device region on the vehicle front side. That is, in the header panel, the middle portion in the longitudinal direction of the vehicle is bent, and the rigidity can be enhanced as compared with the case where the header panel is in the shape of a flat plate not bent. Therefore, in the above vehicle body upper structure, although the electronic device is disposed on the vehicle front side of the header panel and the inner mirror is attached to the vehicle rear side, the mounting rigidity of the inner mirror is high.

  Further, as described above, since the mounting area of the inner mirror is lower than the equipment area, in the state where the header panel is attached, the vicinity of the vehicle front end of the mounting area of the inner mirror opens toward the upper side of the vehicle It can make a recess. The recessed portion can be used as a water receiving portion for receiving water such as dew condensation water falling from the roof panel toward the inside of the header panel. The water received in the recess can be guided to both ends in the vehicle width direction of the header panel along the ridge line formed by the vehicle front end edge of the mounting area which is the lower level, and the equipment forming the level higher than the mounting area It can prevent flowing into the area. Therefore, the vehicle body upper structure described above can prevent water leakage from the inside of the header panel to the electronic device side along the wire passing through the through hole provided in the device area.

(Overview)
The vehicle body upper structure 1 of the first embodiment is provided with a header panel 2 to which an inner mirror 3 is attached, which is used in a portion forward of the vehicle and above the vehicle in a compartment R typically provided in the front of the vehicle .

  As a car in which the vehicle body upper structure 1 is used, for example, a cab-over type car (for example, a truck, a van or the like), a pickup truck or the like can be mentioned. The front of the vehicle body of these vehicles includes a front portion where the headlights are disposed, a pair of left and right side wall portions where the door is disposed, a roof portion provided at upper end edges of both side wall portions, and front portions and both side walls -The windshield 12 attached to the opening part which can be enclosed by a part and a roof part (the details are not shown). The passenger compartment R is formed by the front portion, both side wall portions, the roof portion, and the windshield 12. The roof portion includes a roof panel 10 having an exterior surface, a header panel 2 attached to extend in the vehicle width direction near the front end of the roof panel 10, and a molded ceiling attached to the rear of the vehicle from the rear end of the header panel 2 And a unit (not shown).

  Furthermore, in the above-described automobile, electronic devices (not shown) are disposed at a position on the vehicle front side of the header panel 2 that is near the upper end of the windshield 12. In the header panel 2, a part of the electric wire 5 extending from the electronic device is accommodated. Examples of the above electronic devices include cameras for monitoring the front of a vehicle for the purpose of reducing collision damage, various detection devices such as a laser radar and an ultrasonic sensor, and recording devices such as a drive recorder. The electric wire 5 is used to supply power to the electronic device, transmit a signal, and the like. Here, the electric wire 5 includes a wire harness in which a plurality of electric wires are bundled.

In the vehicle body upper structure 1 of the first embodiment, the header panel 2 has a step portion in which the high level and the low level are arranged in the longitudinal direction of the vehicle. Specifically, the header panel 2 includes the device area 2F on the front side of the vehicle near the arrangement position of the electronic device, the mounting area 2R of the inner mirror 3 on the vehicle rear side, and the mounting area 2R is lower than the device area 2F. It has a step shape that forms a step. By providing such a specific level difference portion, the header panel 2 can be enhanced in rigidity as compared with the case where the device area 2F and the attachment area 2R are aligned in a flush state.
The header panel 2 will be mainly described below.

(Header panel)
The header panel 2 is a bowl-like member which protrudes toward the interior of the compartment R as shown in the cross-sectional view of FIG. 1 and forms a recess 20 with respect to the roof panel 10 (see also FIG. 2) It is attached to the roof panel 10 so as to cover an area near the front end of the vehicle 10 along the vehicle width direction. In this mounted state, the area on the vehicle front side of the header panel 2 (apparatus area 2F) is disposed near the upper end of the windshield 12.

  The header panel 2 of this example has a forming portion of the recess 20 and a flange portion 24 which is a fixing portion to the roof panel 10. As shown in FIG. 2, the location where the recess 20 is formed is sandwiched between the front wall 26 disposed on the front side of the vehicle, the rear wall 27 disposed on the rear side of the vehicle, and both walls 26 and 27. And a lower plate portion 28 that forms the bottom of the recess 20. In this example, the above-described stepped portion is locally provided at the central portion in the vehicle width direction at the location where the recess 20 is formed, and does not have stepped portions on both sides in the vehicle width direction. Further, in this example, the central portion in the vehicle width direction having the step portion protrudes rearward of the vehicle as compared to the portions on both sides in the vehicle width direction. The flange portion 24 is a portion including the vehicle front end of the header panel 2 and provided on the vehicle front side, extends from the front wall portion 26 toward the vehicle front, and is provided along the vehicle width direction.

<Step part>
The stepped portion of the header panel 2 includes a device area 2F disposed on the front side of the vehicle and an attachment area 2R of the inner mirror 3 positioned behind the apparatus area 2F, and the vehicle front end 22 of the attachment area 2R. Is provided at a position lower than the vehicle rear end 21 of the device area 2F (FIG. 1). Such a step portion forms a step having a high level in the device area 2F and a low level in the mounting area 2R, as viewed in the front-rear direction of the vehicle. In this example, the above-described front wall portion 26 is divided up and down near the center in the vehicle width direction, and partially includes an upper side wall 26 u disposed on the vehicle upper side and a lower side wall 26 d disposed on the vehicle lower side. . The lower side wall 26d is provided between the vehicle rear end 21 of the device area 2F and the vehicle front end 22 of the attachment area 2R. Further, in this example, the attachment area 2R of the inner mirror 3 doubles as the central portion in the vehicle width direction of the lower plate portion 28 described above. Therefore, the vehicle front end 22 of the mounting area 2R forms a boundary (ridge line) between the mounting area 2R and the lower side wall 26d, and doubles as a part of a boundary (ridge line) between the lower plate portion 28 and the front wall 26 .

  The device region 2F is a flat and flat region, and is provided with a through hole 25 through which the electric wire 5 connected to the above-described electronic device is passed. The planar shape, size, and the like of the device region 2F can be appropriately selected as long as the through holes 25 of the electric wire 5 described above can be formed.

  The attachment area 2R of the inner mirror 3 is a flat and flat area to which the inner mirror 3 is attached. The attachment area 2R of this example is provided with an attachment hole 23 penetrating in and out of the attachment area 2R. A mounting seat (not shown) is provided in the mounting hole 23, and a mounting bracket (the same) provided on the inner mirror 3 is mounted on the mounting seat by a fastening member (the same) such as a bolt. The planar shape, size, and the like of the attachment area 2R of the inner mirror 3 can be appropriately selected as long as the above-mentioned attachment bracket and the cover part 32 (FIG. 1) described later can be disposed.

  The device area 2F in this example has a trapezoidal shape in a plan view (FIG. 2) and corresponds to the width of the cover 4 (described later, FIG. 1) for housing the electronic device and the length of the vehicle rear portion of the cover 4 It has a width and a length. The attachment area 2R of the inner mirror 3 in this example has a planar shape along the vehicle rear end 21 of the device area 2F and a length corresponding to the length of the attachment bracket. The length of the attachment area 2R is equal to the length of the lower plate portion 28 described above. The width of the mounting area 2R in this example is larger than the width of the mounting bracket and has a width corresponding to the width of the cover 4 of the electronic device, that is, a width corresponding to the width of the device area 2F. If the size of the device area 2F and the mounting area 2R of the inner mirror 3 is such a size, the rigidity is prevented from being lowered due to the header panel 2 becoming longer in the vehicle longitudinal direction, and the rigidity is higher. Here, the width is a size along the vehicle width direction, and the length is a size along the vehicle longitudinal direction.

  If the through hole 25 of the above-mentioned electric wire 5 can penetrate the electric wire 5, an opening shape, the magnitude | size of an opening part, etc. can be selected suitably. If the inner mirror 3 is properly attached to the mounting hole 23, the opening shape, the size of the opening, and the like can be appropriately selected. Although FIG. 2 exemplifies the case where the openings 23 and 25 have a rectangular shape in a plan view, the shape may be changed to a circular hole or a long hole.

(Main effect)
The vehicle body upper structure 1 according to the first embodiment includes the specific step-shaped header panel 2 in which the device area 2F on the front side of the vehicle is high and the attachment area 2R of the inner mirror 3 on the vehicle rear side is low. The rigidity can be enhanced as compared with the case where the step portion is not bent. Therefore, in the vehicle body upper structure 1 of the first embodiment, although the electronic device is disposed on the vehicle front side of the header panel 2 and the inner mirror 3 is attached on the vehicle rear side, the mounting rigidity of the inner mirror is high.

  Furthermore, the vehicle body upper structure 1 of the first embodiment can form a recess opening toward the roof panel 10 near the vehicle front end 22 of the attachment area 2R of the inner mirror 3 by having the above-described step portion. Water such as dew condensation water falling from the roof panel 10 toward the inside of the header panel 2 can be received by the recess. The water received in the recess is led to the outside of the vehicle such as a pillar (not shown) from both ends in the vehicle width direction of the header panel 2 along the ridge line formed by the vehicle front end 22 of the mounting area 2R which is the lower step. be able to. That is, it is possible to prevent the water received in the recess from flowing out to the device area 2F located at a position higher than the attachment area 2R. Therefore, the vehicle body upper structure 1 of the first embodiment can prevent water leakage from the inside of the header panel 2 to the electronic device side along the electric wire 5 inserted and disposed in the through hole 25 of the device area 2F.
