Disclosure of Invention
[ problems to be solved by the invention ]
If the shock absorber housing is coupled to the rear pillar like the above-described vehicle body rear structure, the rigidity becomes excessively high, and the push-up transmission from the suspension deteriorates ride comfort. Therefore, it is necessary to ensure the support rigidity of the suspension without coupling the shock absorber housing to the rear pillar.
The present invention aims to provide a vehicle body rear structure capable of ensuring support rigidity of a suspension without connecting a damper housing to a rear pillar.
[ means for solving problems ]
In order to achieve the above object, the present invention provides a vehicle body rear structure in which a rear seat (for example, a rear seat 70 described later) is coupled to a floor cross member (for example, a floor cross member 22 described later), a seatback (for example, a seatback 71 described later) of the rear seat is provided with a rigid plate (for example, a rigid plate 75 described later) coupled to a seat support portion (for example, a seat support portion 381 described later) disposed above a damper base (for example, a damper base 37 described later) connected to a damper housing (for example, a damper housing 32 described later) of a rear frame (for example, a rear frame 21 described later).
This allows the thrust-up load transmitted from the suspension to be received in the shearing direction of the rigid plate, and the load can be dispersed by the surface. Therefore, the support rigidity of the suspension can be improved.
In this case, it is preferable that the front end of the rigid plate connected to the floor cross member and the rear end of the rigid plate connected to the seat support portion are disposed rearward of the front end of the damper housing and forward of the rear end of the damper housing. This reduces the amount of displacement in the vehicle body longitudinal direction between the damper housing and the rigid plate to which the push-up load is transmitted, and efficiently transmits the push-up load to the rigid plate, thereby improving the rigidity of the rear portion of the vehicle body.
In this case, it is preferable that the rear end of the rigid plate connected to the seat support portion is disposed between the damper base and the floor cross member. This reduces the amount of displacement in the vehicle body longitudinal direction between the damper housing and the rigid plate to which the push-up load is transmitted, and efficiently transmits the push-up load to the rigid plate, thereby improving the rigidity of the rear portion of the vehicle body.
In this case, it is preferable that the damper housing includes: a wheel cover portion (for example, a wheel cover portion 31 described later) connected to the rear frame; and an extension portion (for example, an extension portion 33 described later) extending above the damper housing and having a smaller cross-section than the wheel cover portion; the seat support portion is disposed on the extension portion. This makes it possible to efficiently transmit the push-up load transmitted from the damper housing to the rigid plate, and therefore, the rigidity of the rear portion of the vehicle body can be improved.
In this case, it is preferable that a recess frame (for example, a recess frame 26 described later) which is connected to the rear frame and is formed along the vehicle outer side of a floor recess constituting a tire housing groove (tire housing groove 24 described later) is formed as an annular frame by the damper housing, the rigid plate, and the floor cross member, and a spring support portion (for example, a spring support portion 211 described later) which supports a spring (for example, a spring 54 described later) on the lower surface of the rear frame is disposed between the front end of a retreating plate (for example, a retreating plate 27 described later) and the rear end of the annular frame.
This makes it possible to disperse the push-up load applied from the spring of the suspension to the rigid plate and the annular frame, and to improve the rigidity of the rear portion of the vehicle body.
In this case, it is preferable that the damper base is joined to the outside of the damper housing in the vehicle width direction, and the seat support portion is disposed along a ridge line (for example, a ridge line L described later) forming an outer edge of the extending portion via a mounting bracket (for example, a mounting bracket 382 described later). Thus, the load applied from the damper and the spring can be efficiently transmitted to the rigid plate and the annular frame, and the rigidity of the rear portion of the vehicle body can be improved.
In this case, the upper end of the damper housing is preferably disposed at a distance from a rear pillar (e.g., a rear pillar 62) forming a rear door opening (e.g., a rear door opening 61). Thereby, the push-up load is transmitted to the rigid plate instead of the vehicle body upper frame. Therefore, the vehicle body can be suppressed from twisting while maintaining the ride comfort.
In this case, it is preferable that the rigid plate is provided on the back surface of the seat back. Thereby, the seat can be moved while being laid down, so operability is improved. The back of the seat can be protected from the load.
(Effect of the invention)
According to the present invention, it is possible to provide a vehicle body rear structure capable of ensuring the support rigidity of a suspension without connecting a damper housing to a rear pillar.

Since the front end of the damper housing 32 is located further toward the front side of the vehicle body 10 than the floor cross member 22, the front end of the rigid plate 75 is located rearward of the front end of the damper housing 32. By fixing the rigid plate 75 to the damper housing 32, as shown in fig. 2, an annular frame B is formed by the recess frame 26, the damper housing 32, the rigid plate 75, and the floor cross member 22. More specifically, the damper housing 32, the rigid plate 75 and the floor cross member 22 form a first ring-shaped frame B1, the recess frame 26 and the floor cross member 22 form a second annular frame B2, and the first annular frame B1 and the second annular frame B2 form an annular frame B connected to each other.
According to the present embodiment, the following effects are obtained.
In the present embodiment, the rear seat 70 is coupled to the floor cross member 22, the seat back 71 of the rear seat 70 includes the rigid plate 75, the rigid plate 75 is coupled to the seat support portion 381, and the seat support portion 381 is disposed above the damper base 37 connected to the damper housing 32 of the rear frame 21. This allows the thrust-up load (see arrow A1 in fig. 1 and 2) transmitted from the suspension to be received in the shearing direction of the rigid plate 75, and the load can be dispersed by the surface (see arrow A2 in fig. 1 and 2). Therefore, the support rigidity of the suspension can be improved.
In the present embodiment, the front end of the rigid plate 75 connected to the floor cross member 22 and the rear end of the rigid plate 75 connected to the seat support portion 381 are disposed rearward of the front end of the damper housing 32 and forward of the rear end of the damper housing 32. This reduces the amount of displacement in the vehicle body longitudinal direction between the damper housing 32 and the rigid plate 75 into which the push-up load (see arrow A1 in fig. 1 and 2) is introduced, and efficiently transmits the push-up load to the rigid plate 75, so that the rigidity of the vehicle body rear portion can be improved.
In the present embodiment, the rear end of the rigid plate 75 connected to the seat support portion 381 is disposed between the damper base 37 and the floor cross member 22. This reduces the amount of displacement in the vehicle body longitudinal direction between the damper housing 32 and the rigid plate 75 to which the push-up load is transmitted, and efficiently transmits the push-up load to the rigid plate 75, thereby improving the rigidity of the rear portion of the vehicle body.
In the present embodiment, the damper housing 32 includes: a wheel cover portion 31 connected to the rear frame 21; and an extension portion 33 extending upward of the damper housing 32 and having a smaller cross section than the wheel cover portion 31; the seat support portion 381 is disposed on the extension portion 33. This makes it possible to efficiently transmit the push-up load transmitted from the damper housing 32 to the rigid plate 75, the rigidity of the rear portion of the vehicle body can be improved.
In the present embodiment, the recess frame 26 connected to the rear frame 21 and formed along the vehicle outside of the floor recess constituting the tire housing groove 24 is formed as the annular frame B by the damper housing 32, the rigid plate 75 and the floor cross member 22, and the spring support portion 211 supporting the spring 54 on the lower surface of the rear frame 21 is disposed between the front end of the retreating plate 27 and the rear end of the annular frame B. This makes it possible to disperse the push-up load applied from the spring 54 of the suspension to the rigid plate 75 and the annular frame B, and to increase the rigidity of the rear portion of the vehicle body.
In the present embodiment, the damper base 37 is joined to the vehicle width outer side of the damper housing 32, and the seat support portion 381 is disposed along the ridge line L forming the outer edge of the extending portion 33 via the attachment bracket 382. This makes it possible to efficiently transmit the load applied from the damper 55 and the spring 54 to the rigid plate 75 and the annular frame B, and to enhance the rigidity of the rear portion of the vehicle body.
In the present embodiment, the upper end of the damper housing 32 is disposed at a distance from the rear pillar 62 forming the back door opening 61. Thereby, the push-up load is transmitted to the rigid plate 75 instead of the vehicle body upper frame. Therefore, the vehicle body 10 can be suppressed from twisting while maintaining the ride comfort.
In the present embodiment, a rigid plate 75 is provided on the back surface of the seat back 71. Thereby, the rear seat 70 can be moved while being laid down, so that the operability is improved. The seat back can be protected from loads.
The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like are included in the present invention within a range in which the object of the present invention can be achieved.
For example, the structure of the rigid plate is not limited to the structure of the rigid plate 75 in the present embodiment. For example, as shown in fig. 11, the rigid plate 75A may be provided in a rear portion of the rear seat 70A in the seat back 71A. Thus, the rigid plate 75A is configured to be invisible from the outside of the seat back 71A.
