[0001] The present invention relates to a structure around an exhaust pipe for a vehicle.
Background Art
[0002] For example, in Patent Document 1, there is disclosed an exhaust device for a vehicle including a pair of left and right side members extending in the vehicle front-rear direction, a cross member extending in the vehicle left-right direction and connected to the pair of left and right side members, vehicle-mounted components disposed in front of these, and an exhaust pipe disposed below the cross member.
[0003] As described in Patent Document 1, when a part of the exhaust pipe is located behind the vehicle-mounted components, if the vehicle is rear-ended, the exhaust pipe is pushed toward the vehicle-mounted components and comes into contact with them. Therefore, in this Patent Document 1, it is disclosed that the exhaust device of the vehicle further includes a guide member on the upper part of the exhaust pipe, and the guide member faces the cross member in the vehicle front-rear direction and has an inclined surface that inclines upward toward the rear of the vehicle. According to Patent Document 1, when the vehicle is rear-ended, the inclined surface of the guide member collides with the cross member, and the exhaust pipe is guided by the guide member to move downward and then forward, so that it is possible to prevent the exhaust pipe from contacting the vehicle-mounted components.

Summary of the Invention
Problems to be Solved by the Invention
[0005] The technique described in Patent Document 1 is considered to have a certain effect of preventing the exhaust pipe from contacting the vehicle-mounted components. However, there is still room for further improvement in the configuration for suppressing the contact between the exhaust pipe and the vehicle-mounted components.
[0006] In view of these problems, the present invention aims to provide a vehicle exhaust pipe surrounding structure that more effectively suppresses contact between the exhaust pipe and on-board components. [Means for solving the problem]
[0007] To solve the above problems, a typical configuration of the present invention is a vehicle exhaust pipe peripheral structure comprising: a pair of left and right side members extending in the front-rear direction along the lower side of the floor panel of a vehicle; a cross member extending in the vehicle width direction and connecting the pair of left and right side members; an on-board component positioned between the pair of left and right side members and in front of the cross member; and an exhaust pipe extending below the cross member so as to intersect the cross member in a plan view and routed so as not to contact the on-board component, wherein the vehicle exhaust pipe peripheral structure further comprises a bracket provided on the upper part of the exhaust pipe behind the cross member, the bracket having a contact surface that abuts against the rear surface of the cross member, and the contact surface of the bracket and the rear surface of the cross member are vertical surfaces or inclined surfaces that become lower towards the rear of the vehicle. [Effects of the Invention]
[0008] According to the present invention, contact between the exhaust pipe and vehicle components can be more effectively suppressed. [Brief explanation of the drawing]
[0009] [Figure 1] This is a schematic rear view of a vehicle equipped with a vehicle exhaust pipe peripheral structure according to an embodiment of the present invention. [Figure 2] Figure 1 is a side view of the structure surrounding the vehicle's exhaust pipe. [Figure 3] Figure 1 is a perspective view of the bracket, exhaust pipe, and muffler, which are part of the vehicle exhaust pipe surrounding structure. [Figure 4] Figure 1 shows a conceptual diagram of the cross member and bracket included in the structure surrounding the vehicle's exhaust pipe. [Figure 5]Figure 1 is a side view showing the state of the cross member and bracket of the vehicle exhaust pipe surrounding structure before and after deformation. [Figure 6] This is a rear view schematic showing the configuration of the vehicle in Figure 1 with the addition of a rear suspension frame and mounting parts. [Figure 7] Figure 6 is a side view of the structure surrounding the vehicle's exhaust pipe. [Figure 8] Figure 7 is a cross-sectional view of the coil spring, support part, and muffler, which are part of the vehicle exhaust pipe surrounding structure, as seen from the front. [Figure 9] Figure 1 is a side view showing the operation of the structure around the vehicle's exhaust pipe when the vehicle is rear-ended. [Figure 10] Figure 1 is a side view showing the operation of the structure around the vehicle's exhaust pipe when the vehicle is rear-ended. [Modes for carrying out the invention]
[0010] One embodiment of the present invention is a vehicle exhaust pipe perimeter structure comprising: a pair of left and right side members extending in the front-rear direction along the lower side portion of the floor panel of a vehicle; a cross member extending in the vehicle width direction and connecting the pair of left and right side members; an on-board component positioned between the pair of left and right side members and in front of the cross member; and an exhaust pipe extending below the cross member so as to intersect the cross member in a plan view and routed so as not to contact the on-board component, wherein the vehicle exhaust pipe perimeter structure further comprises a bracket provided on the upper part of the exhaust pipe rearward of the cross member, the bracket having a contact surface that abuts against the rear surface of the cross member, and the contact surface of the bracket and the rear surface of the cross member are vertical surfaces or inclined surfaces that become lower towards the rear of the vehicle.
[0011] According to the present invention, even if the exhaust pipe is pushed forward during a rear-end collision, the contact surface of the bracket moves upward along the rear surface of the cross member, thereby guiding the exhaust pipe upward and preventing it from contacting on-board components.
[0012] The exhaust pipe has an inclined portion that becomes lower as it extends rearward from under the cross member, and a first bent portion that bends upwardly convex at the front end of the inclined portion. The bracket may be provided on the inclined portion.
[0013] According to such a configuration, when the exhaust pipe is pushed forward during a rear-end collision, the bracket rotates about a contact surface that is in contact with the rear surface of the cross member, and the lower end of the bracket moves forward. Then, the inclined portion of the exhaust pipe connected to the lower end of the bracket is pushed forward, and the first bent portion at the front end thereof rises, resulting in a steep gradient posture. On the other hand, since the first bent portion at the front end of the inclined portion of the exhaust pipe is pressed by the upper cross member and does not rise further, the forward movement of the inclined portion of the exhaust pipe is also stopped, and instead, bending at the first bent portion is further promoted. As a result of this behavior, the portion of the exhaust pipe in front of the first bent portion is suppressed from moving forward, and it is possible to more effectively avoid the exhaust pipe from contacting vehicle-mounted components.
[0014] The exhaust pipe has a second bent portion that bends downwardly convex at the rear end of the inclined portion. The vehicle exhaust pipe peripheral structure may further include a muffler connected to the exhaust pipe behind the second bent portion.
[0015] According to this configuration, even when the exhaust pipe is pushed by the muffler during a rear-end collision, the exhaust pipe exhibits a behavior in which bending at the first bent portion at the front end of the inclined portion is further promoted. Therefore, bending is also further promoted at the second bent portion at the rear end of the inclined portion. As a result, forward movement of the inclined portion of the exhaust pipe is suppressed, and it is possible to more effectively avoid the exhaust pipe from contacting vehicle-mounted components.
[0016] The vehicle exhaust pipe peripheral structure further includes a rear suspension frame disposed behind the front surface of the cross member and extending in the vehicle width direction, and a receiving portion provided on the rear suspension frame for supporting a coil spring that absorbs a load applied in the vertical direction of the vehicle. The muffler may be disposed at a position overlapping with a part of the receiving portion in the vehicle width direction and the vertical direction.
[0017] According to this configuration, since the receiving part is arranged in front of the muffler and prevents the muffler from moving forward during a rear-end collision, the movement of the exhaust pipe forward can be more effectively suppressed.
[0018] The bracket preferably has a shape that is convex rearward from the contact surface to the upper part of the exhaust pipe, and the lower end of the contact surface is at the same height as the bottom surface of the cross member.
[0019] According to this configuration, during a rear-end collision, the lower end of the bracket can be easily rotated toward the front side of the vehicle around the contact surface. Therefore, the movement of the exhaust pipe forward can be more effectively suppressed.
Embodiment
[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Dimensions, materials, and other specific numerical values shown in such embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and the drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals to omit redundant explanations, and elements not directly related to the present invention are not shown.
[0021] FIG. 1 is a rear view schematically showing a vehicle 300 equipped with a peripheral structure 100 of an exhaust pipe for a vehicle according to an embodiment of the present invention. In FIG. 1 and all other drawings, the vehicle front-rear direction is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction is indicated by arrows U (upward) and D (downward), respectively.
[0022] As shown in Figure 1, the vehicle exhaust pipe surrounding structure 100 includes a pair of left and right side members 112 and 114 extending in the front-rear direction along the lower side of the floor panel 302, and a cross member 116 extending in the vehicle width direction and connecting the pair of left and right side members 112 and 114. The pair of left and right side members 112 and 114 are positioned at predetermined intervals in the vehicle width direction at their ends. The floor panel 302, which forms the floor of the vehicle 300, is positioned on top of the side members 112 and 114 and the cross member 116.
[0023] Furthermore, as shown in Figure 1, the vehicle exhaust pipe surrounding structure 100 includes a fuel tank 120 as an on-board component. The fuel tank 120 is located below the floor panel 302. The fuel tank 120 is positioned between a pair of left and right side members 112 and 114 and in front of the cross member 116.
[0024] The vehicle exhaust pipe surrounding structure 100 includes a front stay 122 positioned in front of the fuel tank 120 on the underside of the floor panel 302, and a rear stay 124 positioned behind the fuel tank 120 on the underside of the floor panel 302. The vehicle exhaust pipe surrounding structure 100 also includes a tank belt 126 connected to the front stay 122 and the rear stay 124. Thus, the tank belt 126 supports the fuel tank 120 from below.
[0025] The vehicle exhaust pipe surrounding structure 100 includes a spare tire storage compartment 130 located behind the cross member 116 of the floor panel 302. The spare tire storage compartment 130 is formed in a concave shape that extends downwards.
[0026] As shown in Figure 1, the vehicle exhaust pipe surrounding structure 100 includes an exhaust pipe 150 located below the floor panel 302. The exhaust pipe 150 passes to the right of the fuel tank 120 and extends towards the rear of the vehicle. The exhaust pipe 150 is located between a pair of left and right side members 112 and 114. The exhaust pipe 150 extends below the cross member 116 so as to intersect the cross member 116 in a plan view. The exhaust pipe 150 has a curved section 154 that curves along the outer shape of the fuel tank 120 in a plan view. The exhaust pipe 150 is elastically suspended to the side member 114 by a hanger 156 and elastically suspended to the floor panel 302 by a hanger 158.
[0027] The exhaust pipe 150 has a front pipe section 152, a curved section 154 that is continuous with the rear end of the front pipe section 152, and a rear pipe section 160 that is continuous with the rear end of the curved section 154. The front pipe section 152 extends generally in the longitudinal direction of the vehicle.
[0028] Furthermore, the curved section 154 is routed so as not to come into contact with the fuel tank 120. The curved section 154 has a first straight section 154a, a second straight section 154b that is continuous with the rear end of the first straight section 154a, and a third straight section 154c that is continuous with the rear end of the second straight section 154b. The first straight section 154a faces the front of the fuel tank 120, the second straight section 154b faces the side of the fuel tank 120, and the third straight section 154c faces the rear of the fuel tank 120.
[0029] Figure 2 is a side view of the vehicle exhaust pipe surrounding structure 100 shown in Figure 1. As shown in Figure 2, the rear pipe section 160 has a front inclined section 162 that slopes downward as it approaches the front, and a rear inclined section 164 (inclined section) that is continuous with the rear end of the front inclined section 162 and slopes downward as it approaches the rear from below the cross member 116. The rear pipe section 160 also has a subsequent straight section 166 that is continuous with the rear end of the rear inclined section 164 and extends rearward.
[0030] Furthermore, the rear pipe section 160 has a first bend 172 that bends upward convexly at the front end of the rear inclined section 164. The rear inclined section 164 and the front inclined section 162 are connected at the first bend 172 and are arranged in an inverted V shape. Therefore, when the rear inclined section 164 receives a load from the rear, the rear inclined section 164 approaches the front inclined section 162, making it easier for the first bend 172 to move upward.
[0031] Furthermore, the first bent portion 172 is located below the cross member 116 and not below the floor panel 302. Therefore, when the vehicle is rear-ended, the first bent portion 172 contacts the highly rigid cross member 116 and is less likely to contact the less rigid floor panel 302. As a result, the upward movement of the first bent portion 172 does not significantly affect the passenger compartment.
[0032] Furthermore, as shown in Figure 2, a predetermined space 192 is provided between the bottom surface 116t of the cross member 116 and the upper end of the first bent portion 172. Therefore, when the vehicle 300 is rear-ended, the first bent portion 172 is more likely to rise due to the presence of the space 192.
[0033] The rear pipe section 160 has a second bend 174 that bends downward in a convex shape at the rear end of the rear inclined section 164. The rear inclined section 164 and the subsequent straight section 166 are connected at the second bend 174 and are arranged in a V-shape. Therefore, when the rear inclined section 164 receives a load from the rear, the subsequent straight section 166 is pushed forward at its lower end by the rear inclined section 164, making it easier for the first bend 172 to move upward.
[0034] Furthermore, the vehicle exhaust pipe surrounding structure 100 includes a bracket 180 provided on the upper part of the rearward inclined portion 164 of the rear pipe section 160 of the exhaust pipe 150. The bracket 180 is positioned behind the cross member 116.
[0035] Figure 3 is a perspective view of the bracket 180, exhaust pipe 150, and muffler 190 provided in the vehicle exhaust pipe surrounding structure 100 of Figure 1. The bracket 180 has a contact surface 182 that abuts against the rear surface 116k of the cross member 116 (see Figures 2 and 4). The contact surface 182 has a pair of protrusions 182a and 182b that project forward of the vehicle on the right and left sides in the vehicle width direction. The pair of protrusions 182a and 182b have a predetermined height in the vertical direction. The pair of protrusions 182a and 182b abut against the rear surface 116k of the cross member 116. The bottom 182c between the pair of protrusions 182a and 182b is recessed towards the rear of the vehicle.
[0036] Figure 4(a) is a conceptual diagram of the cross member 116 and bracket 180 provided in the vehicle exhaust pipe surrounding structure 100 of Figure 1. As shown in Figure 4(a), the contact surface 182 of the bracket 180 is a vertical surface. Also, the rear surface 116k of the cross member 116 is a vertical surface. The vertical dimension of the contact surface 182 of the bracket 180 is smaller than the vertical dimension of the rear surface 116k of the cross member 116.
[0037] Figure 4(b) is a conceptual diagram of the cross member 216 and bracket 280 provided in a modified vehicle exhaust pipe surrounding structure. As shown in Figure 4(b), in the modified vehicle exhaust pipe surrounding structure, bracket 280 and cross member 216 are used instead of bracket 180 and cross member 116. The contact surface 282 of bracket 280 and the rear surface 216k of cross member 216 are inclined surfaces that become lower towards the rear of the vehicle. The vertical dimension of the contact surface 282 of bracket 280 is smaller than the vertical dimension of the rear surface 216k of cross member 216.
[0038] Figure 4(c) is a conceptual diagram of the cross member 316 and bracket 380 provided in the vehicle exhaust pipe surrounding structure according to the comparative example. As shown in Figure 4(c), in the modified vehicle exhaust pipe surrounding structure, bracket 380 and cross member 316 are used instead of bracket 180 and cross member 116. The contact surface 382 of bracket 380 and the rear surface 316k of cross member 316 are inclined surfaces that become higher as they are directed toward the rear of the vehicle. In the configuration of the comparative example, when the vehicle is rear-ended, the contact surface 382 of bracket 380 may be guided downward along the rear surface 316k of cross member 316.
[0039] Figure 5(a) is a side view showing the state of the cross member 116 and bracket 180 of the vehicle exhaust pipe surrounding structure 100 in Figure 1 before deformation. Figure 5(b) is a side view showing the state of the cross member 116 and bracket 180 of the vehicle exhaust pipe surrounding structure 100 in Figure 1 after deformation. As shown in Figure 5(a), the bracket 180 has a curved shape that is convex to the rear from the contact surface 182 to the top of the exhaust pipe 150. The lower end 182k of the contact surface 182 is at the same height as the bottom surface 116t of the cross member 116. Therefore, when the vehicle 300 is hit from behind, the bracket 180 is more likely to rotate around the lower end 182k of the contact surface 182, as shown in Figure 5(b).
[0040] Furthermore, the vertical dimension of the bracket 180 is greater than the height of the space 192 between the bottom surface 116t of the cross member 116 and the upper end of the first bent portion 172.
[0041] As shown in Figure 2, the vehicle exhaust pipe surrounding structure 100 further includes a muffler 190 connected to the exhaust pipe 150 behind the rearward inclined section 164. The muffler 190 is positioned behind the second bend 174. That is, the muffler 190 is positioned at the rear end of the subsequent straight section 166 that connects behind the second bend 174.
[0042] Figure 6 is a schematic rear view showing the configuration of the vehicle 300 in Figure 1 with the addition of a rear suspension frame 210 and a support portion 230. Figure 7 is a side view of the vehicle exhaust pipe surrounding structure 100 provided on the vehicle 300 in Figure 6. Figure 8 is a cross-sectional view of the coil spring 220, support portion 230, and muffler 190 provided on the vehicle exhaust pipe surrounding structure 100 in Figure 7, viewed from the front. As shown in Figure 6, the vehicle exhaust pipe surrounding structure 100 includes a rear suspension frame 210 that is positioned behind the front of the cross member 116 and extends in the vehicle width direction.
[0043] The vehicle exhaust pipe surrounding structure 100 includes a support portion 230 that supports a coil spring 220 (see Figure 7) that absorbs the vertical load applied to the vehicle 300. The support portion 230 is provided on the rear suspension frame 210. As shown in Figure 7, the coil spring 220 and the support portion 230 are positioned between the cross member 116 and the muffler 190.
[0044] As shown in Figure 8, the muffler 190 is positioned so as to overlap with a portion of the receiving portion 230 in the vehicle width direction. Furthermore, the muffler 190 is positioned so as to overlap with a portion of the receiving portion 230 in the vertical direction. Therefore, the receiving portion 230 is positioned in front of the muffler 190.
[0045] Next, we will explain the operation when vehicle 300 is rear-ended. Figures 9 and 10 are side views showing the operation of the vehicle exhaust pipe surrounding structure 100 when vehicle 300 in Figure 1 is rear-ended. As shown in Figure 9(a), before the rear-end collision, there is a predetermined gap between the fuel tank 120 and the muffler 190.
[0046] If the vehicle 300 is rear-ended in this state, as shown in Figure 9(b), the muffler 190 moves forward, the rear inclined portion 164 is pushed forward, the lower end of the bracket 180 is pushed, and the bracket 180 begins to rotate around the contact surface 182.
[0047] Then, as shown in Figure 10(a), the front inclined portion 162 and the rear inclined portion 164 bend further at the first bend 172 and move closer to each other. Also, the rear inclined portion 164 and the following straight portion 166 bend further at the second bend 174 and move closer to each other. Due to this movement, the front end of the rear inclined portion 164 moves upward, and the rear end of the rear inclined portion 164 rotates while moving downward. At the same time, the rear inclined portion 164 moves upward.
[0048] Then, as shown in Figure 10(b), the inclination angle of the rear inclined portion 164 with respect to the horizontal plane becomes steeper, and the forward movement of the muffler 190 stops. The muffler 190 is difficult to move forward by the length of the rear inclined portion 164 in its initial state.
[0049] With the above configuration, in the event of a rear-end collision, the contact surface 182 of the bracket 180 moves upward along the rear surface 116k of the cross member 116, thereby guiding the exhaust pipe 150 upward and preventing the exhaust pipe 150 from contacting the fuel tank 120.
[0050] Furthermore, even if the exhaust pipe 150 is pushed forward during a rear-end collision, the bracket 180 rotates around the contact surface that abuts the rear surface 116k of the cross member 116, causing the lower end of the bracket 180 to move forward. As a result, the rear inclined portion 164 of the exhaust pipe 150, which is connected to the lower end of the bracket 180, is pushed forward, and the first bend 172 at its front end rises, resulting in a steeply sloped posture. On the other hand, the first bend 172 at the front end of the rear inclined portion 164 of the exhaust pipe 150 is held down by the upper cross member 116 and does not rise any further, thus preventing the rear inclined portion 164 of the exhaust pipe 150 from moving forward, and instead resulting in a greater promotion of bending at the first bend 172. This behavior suppresses the forward movement of the portion of the exhaust pipe 150 in front of the first bend 172, making it possible to more effectively avoid the exhaust pipe 150 contacting the fuel tank 120.
[0051] Furthermore, even if the exhaust pipe 150 is pushed by the muffler 190 during a rear-end collision, the exhaust pipe 150 behaves in a way that further promotes bending at the first bend 172 at the front end of the rear inclined portion 164, and consequently, bending is further promoted at the second bend 174 at the rear end of the rear inclined portion 164. As a result, the forward movement of the rear inclined portion 164 of the exhaust pipe 150 is suppressed, and contact between the exhaust pipe 150 and the fuel tank 120 can be more effectively avoided.
[0052] Furthermore, since the receiving portion 230 is positioned in front of the muffler 190, preventing the muffler 190 from moving forward during a rear-end collision, the forward movement of the exhaust pipe 150 is more effectively suppressed.
[0053] Furthermore, the bracket 180 has a curved shape that is convex to the rear from the contact surface 182 to the top of the exhaust pipe 150, and the lower end 182k of the contact surface 182 is at the same height as the bottom surface 116t of the cross member 116. As a result, the lower end of the bracket 180 can easily rotate towards the front of the vehicle around the contact surface 182 during a rear-end collision. This more effectively suppresses the forward movement of the exhaust pipe 150.
[0054] In the above-described embodiment, a fuel tank 120 was used as an example of an on-board component, but the configuration is not limited to this. For example, a battery may be used as an on-board component.
[0055] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these examples. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.
[0056] Furthermore, the present invention can be implemented by freely combining the inventions described in the claims and examples, regardless of the dependency relationships of the claims. [Industrial applicability]
