Description

本発明は、車体後部構造の改良に関するものである。   The present invention relates to an improvement in a vehicle body rear structure.

従来の車体後部構造として、後輪のホイールハウス近傍に設けられた上下のクロスメンバ同士をガセットで繋いだリヤボディ構造が知られている（例えば、特許文献１参照。）。
特開２００６−１６８４３４公報 As a conventional vehicle body rear structure, a rear body structure in which upper and lower cross members provided in the vicinity of a wheel house of a rear wheel are connected by a gusset is known (for example, see Patent Document 1).
JP 2006-168434 A

特許文献１の図１を以下の図５で説明する。なお、符号は振り直した。
図５は従来の車体後部構造を示す斜視図であり、リヤボディ構造１００は、後輪のホイールハウス１０２に隣接するように車両前後方向に延びる左右一対のサイドメンバ１０３，１０３（一方の符号１０３のみ示す。）が設けられ、左右のサイドメンバ１０３，１０３間にセンターフロアクロスメンバ１０４が渡され、このセンターフロアクロスメンバ１０４の後上方位置に車幅方向に延びるアッパバックメンバ１０６が設けられている。 FIG. 1 of Patent Document 1 will be described with reference to FIG. In addition, the code | symbol was reassigned.
FIG. 5 is a perspective view showing a conventional rear structure of a vehicle body. A rear body structure 100 includes a pair of left and right side members 103, 103 (only one reference numeral 103) extending in the vehicle front-rear direction so as to be adjacent to a wheel house 102 of a rear wheel. The center floor cross member 104 is passed between the left and right side members 103, and an upper back member 106 extending in the vehicle width direction is provided at a rear upper position of the center floor cross member 104. .

ホイールハウス１０２から車体内方に膨出されてリヤサスペンションが取付けられるリヤサスペンション部１０７とアッパバックメンバ１０６とに第一補強部材１１１が取付けられ、センターフロアクロスメンバ１０４とアッパバックメンバ１０６のそれぞれの端に第二補強部材１１２が取付けられている。   A first reinforcing member 111 is attached to a rear suspension portion 107 and an upper back member 106 that are bulged inward from the wheel house 102 and to which a rear suspension is attached, and the center floor cross member 104 and the upper back member 106 are respectively A second reinforcing member 112 is attached to the end.

例えば、リヤサスペンションからリヤサスペンション部１０７に荷重が入力されると、リヤサスペンション部１０７と第一補強部材１１１とは簡単に接合されているだけであるから、リヤサスペンション部１０７と第一補強部材１１１との接合部の剛性が小さく、接合部での変形やこの変形に伴う振動が発生しやすい。センターフロアクロスメンバ１０４と第二補強部材１１２との接合部についても同様である。
本発明の目的は、リヤサスペンションからの荷重入力部の剛性を高め、変形や振動を抑制可能な車体後部構造を提供することにある。 For example, when a load is input from the rear suspension to the rear suspension portion 107, the rear suspension portion 107 and the first reinforcement member 111 are simply joined together. The joint has a small rigidity, and deformation at the joint and vibration associated with this deformation are likely to occur. The same applies to the joint portion between the center floor cross member 104 and the second reinforcing member 112.
An object of the present invention is to provide a vehicle body rear structure capable of increasing the rigidity of a load input portion from a rear suspension and suppressing deformation and vibration.

請求項１に係る発明は、車室とトランクルームとを仕切るリヤバルクヘッドが設けられた車体後部構造において、リヤサスペンションを支持するリヤサブフレームが取付けられるリヤサブフレームマウントブラケットと、左右のリヤホイールハウスの各上部間に渡されたリヤパーセルシェルフメンバとがリヤバルクヘッドガセットで直接連結され、このリヤバルクヘッドガセットが、リヤサブフレームマウントブラケット及びリヤフレームと重ねられて３枚が共に溶接されていることを特徴とする。   According to a first aspect of the present invention, there is provided a rear body structure provided with a rear bulkhead that partitions a passenger compartment and a trunk room, a rear subframe mounting bracket to which a rear subframe for supporting a rear suspension is attached, and left and right rear wheel houses. The rear parcel shelf members passed between the upper parts of the two are directly connected by a rear bulkhead gusset, and this rear bulkhead gusset is overlapped with the rear subframe mounting bracket and the rear frame, and the three are welded together. It is characterized by that.

作用として、リヤサスペンションからの荷重入力部を、リヤバルクヘッドガセット、リヤサブフレームマウントブラケット、リヤフレームを共に重ねてこれらの３枚が共に溶接されるようにすることで、荷重入力部の剛性が高くなり、荷重入力部の変形や、この変形に伴う振動が抑制される。   As a function, the load input part from the rear suspension is overlapped with the rear bulkhead gusset, the rear subframe mount bracket, and the rear frame so that these three parts are welded together. It becomes high and the deformation | transformation of a load input part and the vibration accompanying this deformation are suppressed.

請求項１に係る発明では、リヤサスペンションを支持するリヤサブフレームが取付けられるリヤサブフレームマウントブラケットと、左右のリヤホイールハウスの各上部間に渡されたリヤパーセルシェルフメンバとがリヤバルクヘッドガセットで直接連結され、このリヤバルクヘッドガセットが、リヤサブフレームマウントブラケット及びリヤフレームと重ねられて３枚が共に溶接されるので、リヤサブフレームからリヤフレームへの荷重入力部を、リヤバルクヘッドガセット、リヤサブフレームマウントブラケット及びリヤフレームが３枚重ねられた部分で受ける構造にすることで剛性を高めることができ、変形、振動を抑えることができ、また、変形、振動を抑制できる剛性を確保した上で車体後部構造の軽量化を図ることができる。   In the invention according to claim 1, the rear sub-frame mount bracket to which the rear sub-frame for supporting the rear suspension is attached and the rear parcel shelf member passed between the upper portions of the left and right rear wheel houses are the rear bulkhead gussets. Directly connected, this rear bulkhead gusset is overlapped with the rear subframe mount bracket and the rear frame, and the three are welded together, so the load input section from the rear subframe to the rear frame is connected to the rear bulkhead gusset, Rigidity can be increased by adopting a structure in which the rear subframe mount bracket and the rear frame are received by three overlapping parts, deformation and vibration can be suppressed, and rigidity that can suppress deformation and vibration is ensured. The weight reduction of the rear body structure can be achieved.

以上に述べた車体後部構造の実施形態の作用を比較例とともに次に説明する。
図４（ａ），（ｂ）は車体後部構造の作用を示す作用図である。
（ａ）は車体後部構造の比較例であり、リヤボディ１２０は、車体後部を前後方向に延びるリヤフレーム１２１と、このリヤフレーム１２１にリヤサブフレームマウントブラケット１２２を介して取付けられた車幅方向に延びるリヤクロスメンバ１２３と、これらのリヤフレーム１２１及びリヤクロスメンバ１２３のそれぞれの上部に取付けられたリヤフロア１２４と、リヤフレーム１２１の外側部に取付けられた後輪用のリヤホイールハウス１２６と、このリヤホイールハウス１２６の上部内面に一端が取付けられた車幅方向に延びるリヤパーセルシェルフメンバ１２７と、リヤフロア１２４及びリヤパーセルシェルフメンバ１２７のそれぞれに渡されるとともにリヤホイールハウス１２６に取付けられたリヤバルクヘッドガセット１２８と、リヤサスペンションを支持するためにリヤサブフレームマウントブラケット１２２の下面に取付けられたリヤサブフレーム１３１とを備える。 The operation of the embodiment of the vehicle body rear structure described above will be described next together with a comparative example.
4A and 4B are operation diagrams showing the operation of the vehicle body rear structure.
(A) is a comparative example of the rear structure of the vehicle body. The rear body 120 has a rear frame 121 extending in the front-rear direction at the rear of the vehicle body, and a vehicle width direction attached to the rear frame 121 via a rear subframe mount bracket 122. A rear cross member 123 extending, a rear floor 124 attached to the upper part of each of the rear frame 121 and the rear cross member 123, a rear wheel house 126 for a rear wheel attached to an outer portion of the rear frame 121, and A rear parcel shelf member 127 extending in the vehicle width direction having one end attached to the inner surface of the upper portion of the rear wheel house 126, and a rear bulkhead passed to the rear floor 124 and the rear parcel shelf member 127 and attached to the rear wheel house 126. Gusset 128 , And a rear sub-frame 131 attached to the lower surface of the rear sub-frame mounting brackets 122 to support the rear suspension.

例えば、白抜き矢印Ａで示すように、リヤサブフレーム１３１にリヤサスペンションから荷重が入力されると、この荷重はリヤサブフレームマウントブラケット１２２を介してリヤフレーム１２１に伝わり、リヤフレーム１２１を図の二点鎖線で示すように局部的に変形させ、振動を発生させることがある。従って、上記の荷重が、リヤフレーム１２１よりも上方のリヤバルクヘッドガセット１２８、リヤパーセルシェルフメンバ１２７に伝わらないため、リヤフレーム１２１の変形、振動が更に大きくなる可能性がある。   For example, as shown by the white arrow A, when a load is input from the rear suspension to the rear subframe 131, this load is transmitted to the rear frame 121 via the rear subframe mount bracket 122, and the rear frame 121 is shown in FIG. As indicated by a two-dot chain line, it may be locally deformed to generate vibration. Therefore, since the load is not transmitted to the rear bulkhead gusset 128 and the rear parcel shelf member 127 above the rear frame 121, the deformation and vibration of the rear frame 121 may be further increased.

（ｂ）は実施例（本実施形態）の車体後部構造を示している。リヤフレーム１１内にリヤバルクヘッドガセット１８が挿入され、更に、リヤバルクヘッドガセット１８、リヤフレーム１１及びリヤサブフレームマウントブラケット２１が共に溶接されて高剛性部としての入力部３２が形成されているため、白抜き矢印Ｂで示すように、リヤサブフレームマウントブラケット２１にリヤサスペンションから荷重が入力された場合に、この荷重を高剛性の入力部３２で支持することができるとともに、白抜き矢印Ｃ〜白抜き矢印Ｆで示すように、荷重をリヤバルクヘッドガセット１８及びリヤパーセルシェルフメンバ１７に伝えることができる。   (B) has shown the vehicle body rear part structure of the Example (this embodiment). A rear bulkhead gusset 18 is inserted into the rear frame 11, and the rear bulkhead gusset 18, the rear frame 11, and the rear subframe mount bracket 21 are welded together to form an input portion 32 as a highly rigid portion. Therefore, as shown by the white arrow B, when a load is input from the rear suspension to the rear subframe mount bracket 21, this load can be supported by the high-rigidity input portion 32, and the white arrow C The load can be transmitted to the rear bulkhead gusset 18 and the rear parcel shelf member 17 as indicated by the white arrow F.

従って、各フレームが局部的に変形することがなく、振動を発生しにくくすることができるとともに、リヤバルクヘッド２７の全体で荷重を受けることができ、リヤバルクヘッド２７を構成する部品の軽量化を図ることができる。   Accordingly, each frame is not locally deformed, it is possible to make it difficult for vibration to occur, and the entire rear bulk head 27 can receive a load, and the weight of the components constituting the rear bulk head 27 can be reduced. Can be achieved.

以上の図１、図３に示したように、車室とトランクルームとを仕切るリヤバルクヘッド２７が設けられた車体後部構造において、リヤサスペンションを支持するリヤサブフレーム３１が取付けられるリヤサブフレームマウントブラケット２１と、左右のリヤホイールハウス１４の各上部間に渡されたリヤパーセルシェルフメンバ１７とがリヤバルクヘッドガセット１８で直接連結され、このリヤバルクヘッドガセット１８が、リヤサブフレームマウントブラケット２１及びリヤフレーム１１と重ねられて３枚が共に溶接されているので、リヤサブフレーム３１からリヤフレーム１１への荷重の入力部３２を、リヤバルクヘッドガセット１８、リヤサブフレームマウントブラケット２１及びリヤフレーム１１が３枚重ねられた部分で受ける構造にすることで剛性を高めることができ、変形、振動を抑えることができ、また、変形、振動を抑制できる剛性を確保した上で車体後部構造、即ち、リヤバルクヘッド２７の軽量化を図ることができる。   As shown in FIGS. 1 and 3, the rear subframe mount bracket to which the rear subframe 31 for supporting the rear suspension is attached is provided in the rear structure of the vehicle body provided with the rear bulkhead 27 that partitions the vehicle compartment and the trunk room. 21 and a rear parcel shelf member 17 passed between the upper portions of the left and right rear wheel houses 14 are directly connected by a rear bulkhead gusset 18, and the rear bulkhead gusset 18 is connected to the rear subframe mount bracket 21 and the rear Since the three pieces are overlapped with the frame 11 and welded together, the load input portion 32 from the rear subframe 31 to the rear frame 11 is connected to the rear bulkhead gusset 18, the rear subframe mount bracket 21, and the rear frame 11. Structure that is received at the part where three sheets are stacked As a result, rigidity can be increased, deformation and vibration can be suppressed, and the rear structure of the vehicle body, that is, the rear bulkhead 27 can be reduced in weight while ensuring rigidity capable of suppressing deformation and vibration. it can.
