Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. Here, the upper, lower, front, rear, left, and right of the vehicle body are defined based on the line of sight of the occupant riding the motorcycle.

Fig. 1 schematically shows an external appearance of a motorcycle as a vehicle according to an embodiment of the present invention. The vehicle 11 includes a vehicle body 12. The vehicle body 12 includes: left and right side plates 15 partitioning a door opening 14 for accommodating the side door 13; and a roof 16 connecting upper ends of the left and right side panels 15 to each other. A rear bumper (rear bumper)17 is coupled to the left and right side plates 15 from the rear. The rear bumper 17 connects the left and right side plates 15 to each other. The side panel 15 includes an outer panel (15 a) that contributes to an aesthetic improvement by a painted outer surface.

The roof 16 supports a rear door 18 so as to be swingable about a horizontal axis. A door opening 19 for accommodating a rear door 18 is defined above the rear bumper 17 of the vehicle body 12. The door opening 19 is opened and closed by the rear door 18.

As shown in fig. 2, the vehicle body 12 further includes: a damper cover 21 that is rigidly coupled to the side inner panel 15b and supports a damper (not shown) for the rear wheel; and a damper reinforcement 22 rigidly joined to the side inner panel 15b and extending upward from the damper cover 21. The side inner panel 15b is covered from the outside by the outer panel 15a, and forms a side panel 15 in cooperation with the outer panel 15 a. The damper reinforcement 22 includes a hollow body 22a, and a closed section is formed between the hollow body 22a and the side inner panel 15 b. A rear pillar 23 is coupled to each side plate 15, and the rear pillar 23 partitions left and right edge portions of the door opening 19 opened and closed by the rear door 18. The side plate 15 extends forward from the rear pillar 23. The absorber reinforcement 22 is disposed apart from the rear pillar 23 by a distance Ds, for example.

As shown in fig. 3, the vehicle body 12 further includes a cross member 24, and the cross member 24 connects upper ends of the left and right rear pillars 23 to each other and supports the roof 16 from below. The cross member 24 divides the upper end of the door opening 19.

The rear pillar 23 includes a pillar inner portion 23a, and the pillar inner portion 23a is rigidly joined to the inner surface of the side inner panel 15 b. For example, welding may be used for joining. The column inner 23a is connected at an upper end to a side end of the cross member 24. The column inner portion 23a has: a front wall 26a rising inward from the weld 25 overlapping the inner surface of the side inner panel; and an inner wall 26b extending rearward from an inner end of the front wall 26 a. Above the absorber reinforcement 22, a retractor bracket 27 that supports a seatbelt retractor is joined to the pillar inner portion 23 a. Above the retractor bracket 27, a belt anchor 28 is fixed to the side inner panel 15 b. The seatbelt retractor is used to adjust the length of a seatbelt attached to a passenger. The belt anchor 28 is used when the shoulder belt of the seat belt is fixed to the rear pillar 23.

As shown in fig. 4, the rear pillar 23 includes a pillar outer portion 23b joined to the pillar inner portion 23a from the outside. As shown in fig. 5, the post inner portion 23a and the post outer portion 23b cooperate to form a closed cross-section. The column outer portion 23b includes: a rear wall 29a engaged at an inner edge with the outer surface of the post inner portion 23a and extending outwardly from the outer surface of the post inner portion 23 a; a side wall 29b extending forward from an upper end of the rear wall 29 a; and a front wall 29c that extends continuously from the front end of the side wall 29b toward the inner side panel 15b, is laminated to the weld 25 of the pillar inner 23a at the weld 31, and sandwiches the inner side panel 15b with the weld 25. The weld 25 of the pillar inner portion 23a, the rear edge of the side inner panel 15b, and the weld 31 of the pillar outer portion 23b are stacked in this order and rigidly joined. For example, welding may be used for joining.

An extension flange 32 is formed at the pillar outer portion 23b at the position of the webbing anchor 28, and the extension flange 32 extends to a position further forward than the pillar inner portion 23 a. The extension flange 32 may be formed from a continuous sheet of material from the weld site 31. The extension flange 32 overlaps with the outer surface of the side inner panel 15 b. An anchor plate 33 supporting the belt anchor 28 is overlapped on the extension flange 32. The extension flange 32 overlaps the anchor plate 33 from the inside and supports the anchor plate 33 from the inside. Thus, the anchor plate 33 is engaged to the rear pillar 23.

Here, the side inner panel 15b, the extension flange 32, and the anchor panel 33 overlap and are joined to each other at the first joining region 34. The first joining region 34 is constituted by a welding point (welding trace), for example. The first engagement area 34 is arranged along the periphery of the anchor plate 33. Here, four points are set along the circumference. The extension flange 32 is expanded to a first engagement area 34a set at the front end of the anchor plate 33. The side inner panel 15b includes a convex structure 35 bulging to the vehicle outside as approaching the first joining region 34.

The weld site 31 of the pillar outer portion 23b is joined to the outer surface of the inner side panel 15b at the second joint region 36. The second joining region 36 is constituted by a welding point (welding trace), for example. As shown in fig. 3, the rear end of the side inner panel 15b is joined to the pillar inner 23a at the second joining region 36. In this way, the rear end of the side inner panel 15b is sandwiched and joined between the pillar inner portion 23a and the pillar outer portion 23b at the second joining region 36.

As shown in fig. 6, the retractor bracket 27 engages the pillar inner 23 a. Includes a plurality of mounting

pieces

37a, 37b, 37c, 37 d. At least one of the mounting tabs 37a overlaps and is rigidly joined to the post outer portion 23b and the post inner portion 23 a. For example, welding may be used for joining.

The pillar inner 23a has a protruding portion 39 that protrudes toward the front of the vehicle body at the height of the anchor plate 28 and is joined to the side inner panel 15b at the third joining region 38. The projection 39 may be bent continuously from the plate material of the column inner portion 23a from the welding portion 25. The third joining region 38 is formed by a welding point (welding trace), for example.

When a large load acts forward on a seat belt-wearing occupant, the load is transmitted from the shoulder belt to the seat belt anchor 28. At this time, the rear pillar 23 can satisfactorily support the tensile load acting on the belt anchor 28 by the closed cross section. That is, the toppling of the anchor plate 33 can be suppressed. Since the support for the belt anchor 28 is released from the damper reinforcing member 22, the degree of freedom in designing the damper reinforcing member 22 can be expanded. The riding comfort can be well adjusted.

In the vehicle body 12 of the present embodiment, the side inner panel 15b, the extension flange 32, and the anchor plate 33 are overlapped and joined to each other in the first joining region 34. Since the three members are overlapped and joined, the support strength of the seat belt can be sufficiently ensured based on the increase of the total plate thickness. Further, since the first joining region 34 is disposed along the peripheral edge of the anchor plate 33, the closed cross section of the rear pillar 23 can be utilized more efficiently via the pillar outer portion 23b when supporting the tensile load applied by the webbing anchor 28. The toppling of the anchor plate 28 can be well suppressed.

In the present embodiment, the extension flange 32 is expanded to a first engagement area 34a set at the front end of the anchor plate 33. As a result, the closed cross section of the rear pillar 23 can be utilized more efficiently via the pillar outer portion 23b when supporting the tensile load applied by the webbing anchor 28. The toppling of the anchor plate 28 can be well suppressed.

The rear end of the side inner panel 15b is joined between the pillar inner 23a and the pillar outer 23b at the second joint region 36. The support strength of the seat belt can be further improved by the second joint region 36.

The pillar inner 23a of the present embodiment has a protruding portion 39 that protrudes forward of the vehicle body at the height of the anchor plate 33 and is joined to the side inner panel 15b at the third joining region 38. Since the pillar inner 23a is engaged with the side plate 15 at the position of the anchor plate 33, the closed cross section of the rear pillar 23 can be utilized more efficiently when supporting the tensile load applied by the webbing anchor 28. The toppling of the anchor plate 33 can be well suppressed.

In the present embodiment, the side inner panel 15b includes a convex structure 35 that bulges outward as it approaches the first joint region 34. Since the side inner panel 15b supports the anchor panel 33 in the convex structure 35, the side panel 15 can contribute to supporting the tensile load applied by the belt anchor 28. The supporting strength of the seat belt can be further improved.

The retractor bracket 27 has a mounting piece 37a that overlaps and engages with the pillar outer portion 23b and the pillar inner portion 23 a. By overlapping and joining the mounting piece 37a of the retractor bracket 27 with the pillar inner 23a and the pillar outer 23b, the support rigidity of the seatbelt retractor can be secured.

In the vehicle body 12 of the present embodiment, the absorber reinforcement 22 is disposed separately from the rear pillar 23. In this way, since the rear pillar 23 is separated from the damper reinforcement 22, the strength of the damper reinforcement 22 can be freely set, and as a result, the push-up rigidity from the damper can be alleviated. The push-up stiffness can be adjusted to be optimal. Adjustment of the push-up rigidity can contribute to improvement of ride comfort. In this way, the support strength of the webbing anchor 28 can be ensured while adjusting the push-up rigidity. At this time, the damper reinforcement 22 includes a hollow body 22a, and a closed section is formed between the hollow body 22a and the side inner panel 15b, so the damper reinforcement 22 may contribute to reinforcement of push-up rigidity.
