no. 1 approach

[0065] First, a first embodiment will be described with reference to FIGS. 1 to 24 . In the following description, FIGS. 1 to 24 show only the right side of the vehicle 1, but the left side of the vehicle 1 also has the same structure.

[0066] Referring to FIGS. 1 to 3 , the vehicle 1 according to the first embodiment is a vehicle such as a single box car, which has a roof 10 constituting the roof of the vehicle compartment; an underbody 20 constituting the floor of the compartment; Between the roof 10 and the underbody 20, a side wall 30 constituting the side of the vehicle body; between the roof 10 and the underbody 20, a rear wall 40 constituting the rear of the vehicle; formed on the underbody 20 Between the vehicle body side wall portion 30 is a wheel house 50 for accommodating rear wheels (not shown).

[0067] The roof 10 includes roof reinforcement members 11 and 12 arranged front and rear and extending in the vehicle width direction (see FIG. 3 ). The roof reinforceme...

no. 2 approach

[0151] Next, a second embodiment will be described. However, in each of the following embodiments, the same components as those in the first embodiment are given the same reference numerals, and description thereof will be omitted.

[0152] Referring to FIGS. 25 and 26 , in the second embodiment shown in the figures, a member independent of the main floor 21 , that is, a bottom reinforcement member 28 is provided at the upper end of the rear side member 22 .

[0153] Referring to FIG. 27 at the same time, the bottom reinforcement member 28 is a substantially rectangular plate-shaped member, and its thickness is about twice (1.0 mm) that of the main base plate 21 (for example, 0.5 mm). The outer side of the bottom reinforcement member 28 in the vehicle width direction has a flange 28 a formed along the contour of the lower end portion of the wheel house inner 51 . As shown in FIG. 27, the flange 28a extends along the lower end contour of the wheel house inner member 51 in a pa...

no. 3 approach

[0161] Fig. 28 relating to the third embodiment is a side view showing the rear part of the vehicle body provided with the seat belt. In this FIG. 28 , a portion of the inner panel 31 located at the periphery of the rear window opening 36 is removed (part B of FIG. 28 ).

[0162] Referring to FIG. 28 , the vehicle body side wall portion 30 of the vehicle 1 is provided with seat belts 150 respectively corresponding to the second row of seats and the third row of seats (both not shown), which can restrain the occupants seated in these seats. and 140.

[0163] The seat belt 140 for the third row of seats is equipped with a seat belt retractor (seat belt retractor) 141 for taking up and accommodating the seat belt 140 at one end thereof, and the seat belt retractor 141 is connected and fixed to the seat belt 140 by a fixing bolt 143. On the bracket part 73. On the other hand, the other end of the seat belt 140 is attached with a lower support member 145 such as an anchor plate, ...

Abstract

A vehicle body structure of the invention, comprises: a body side wall part (30) configured a vehicle body side part; a wheel cover (50) provided down the body side wall part (30) has an assembly part for mounting a rear suspension; a side column enhancing component (34), for enhancing the side column, arraged on the side column over the wheel cover, extending along the vehicle body up and down; a posterior column enhancing component (45) for enhancing the posterior column, arraged on the posterior column behind the vehicle body of the wheel cover, extending along the vehicle body up and down; a first connecting component (56) for connecting the side column enhancing component and the lower end of the wheel cover; a second connecting component (70, 80) for connecting the posterior column enhancing component and neighborhood parts of the assembly part of the wheel cover; and a third connecting component (39) for connecting the side column enhancing component and the posterior column enhancing component. According to the invention, torsional rigidity of the body side wall part behind the vehicle body can be improved.

Description

technical field [0001] The present invention relates to a vehicle body structure used in vehicles such as automobiles, and specifically relates to a vehicle body structure from a portion near a wheelhouse of a rear wheel to a portion behind the rear wheel. Background technique [0002] As is well known, in a vehicle such as an automobile, a wheel house is formed on a side wall of a vehicle body where a rear wheel is provided, and a rear suspension system (rear suspension system) for suspending the rear wheel is attached to the wheel house. When the vehicle is running, a load is repeatedly transmitted from the rear suspension device to the wheel house substantially in the vertical direction. [0003] In the above-mentioned vehicle, in order to suppress deformation of the vehicle body and improve steering stability, it is desired to effectively distribute the above-mentioned load transmitted from the rear suspension device to the wheel house to ...
