Problems solved by technology

[0010] However, in the vehicle bumper structure of the above-mentioned Patent Document 1, because the bumper member is clamped and connected to the side panel by the plate-shaped fixed support frame, when a large lateral impact force is applied to the side surface of the side panel, it will There is a problem that the fixed support bracket is detached\or deformed from the bumper part and cannot fully transmit the side impact force to the bumper part
[0011] In addition, in the vehicle bumper structure of the above-mentioned Patent Document 2, instead of transmitting the lateral impact force applied to the side plate to the cross frame, the entire floor portion receives the lateral impact force, For example, when there is no upper support like a convertible, or even if there is an upper support but its rigidity is low, there is a problem that the entire vehicle body cannot sufficiently absorb the lateral impact force

Embodiment approach 1

[0087] Fig. 1 is a perspective view of the rear part of the seat 4 (shown by the dashed line 2 in Fig. 1 ) of the car body 1 in the convertible car. The vehicle body 1 includes: a front rib portion 3 , an upwardly bent portion 5 obliquely extending from the front rib portion 3 toward the rear of the vehicle body, a rear rib portion 7 , and left and right side panels 9 . Also, at the boundary between the upper end portion of the upwardly bent portion 5 and the rear rib portion 7, a horizontal frame 6 connecting the left and right side panels 9 is provided. In addition, in FIG. 1 , the side panel 9 on the left side in the vehicle width direction is omitted.

[0088] As enlargedly shown in FIG. 2 , the vehicle bumper structure 11 according to the present embodiment is provided on the left and right side panels 9 to connect the left and right side panels 9 . This vehicle bumper structure 11 is provided below the beltline 12 (beltline 12) of the convertible car, includes a crossba...

Embodiment approach 2

[0116] 7 and 8 show Embodiment 2 of the present invention, which is different from Embodiment 1 above in that the structure of the fixed support frame 19 is different. In addition, the same reference numerals are used for the same parts as in FIGS. 1 to 4 , and detailed description thereof will be omitted.

[0117] As shown in FIG. 7, two screw holes (not shown in the figure) are provided on the cross member 13 on the inner side in the vehicle width direction than the extension portion 16 of the bumper member 15. On these screw holes, bolts 50 A substantially rectangular plate-shaped loudspeaker mounting support frame 25 as a supporting member is fixed. On the reverse side of this speaker mounting bracket 25, a speaker 26 as a vehicle-mounted device is mounted.

[0118] The vehicle width direction outer lower end portion of the above-mentioned loudspeaker mounting support frame 25 is also fixed by bolts 50 in the vehicle width direction of the fixed support frame 19 . As sho...

Embodiment approach 3

[0139] Fig. 2 shows the side body structure 2 on the rear side of the right side vehicle seat (not shown) in the convertible car. This side vehicle body structure 2 includes: a front rib portion 3 extending in the front-rear direction of the vehicle body, an upwardly bent portion 5 extending obliquely from the front rib portion 3 to the rear side of the vehicle body, and a rear rib portion 5 extending rearwardly. Rib portion 7, and left and right side panels 9. Also, as shown in FIG. 12, a horizontal frame 6 extending in the vehicle width direction is provided behind the upwardly bent portion 5. As shown in FIG.

[0140] As shown in Figure 13, the above-mentioned upward bending part 5 has its upper end bent backward, and the front side horizontal part of the "L" shaped part is welded on the back near its upper end, and the horizontal part is extended upwards from this horizontal part. The upper end of the rear side vertical part is welded to the front end side of the rear rib...

Abstract

To effectively absorb a side collision load by transmitting the load applied to a side panel 9 to a cross member 6 in a side vehicle body structure 1 of a vehicle.

Description

technical field [0001] The present invention relates to a vehicle bumper structure. Background technique [0002] Hitherto, convertible cars have been provided with vehicle safety components extending in the up-down direction of the car body in order to protect the head of the occupant when the car rolls over. In order to increase the strength of this vehicle safety member, it is known to combine the vehicle safety member with a reinforcing member (connection member) extending in the vehicle width direction. [0003] For example, in Patent Document 1, a connecting member extending in the vehicle width direction is fixed on a bracket (Bracket) for supporting the hood fixed on a side panel (Sid Panel), and the connecting member is fixedly supported by a plate. It is also known that the frame encloses the vehicle insurance component, and then links the vehicle insurance component and the side plate by the connecting component. [0004] By connecting the vehicle insurance comp...
