Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above - mentioned Patent Document 1, there is no specific description of what supports the "fuel pipe 45". Also, in paragraph 0044 of the above - mentioned Patent Document 1, it is described that "the coolant pipe 46 is held by the clamp member 52", but there is no specific description of what it is supported by.

[0005] Incidentally, in vehicles where a battery pack is installed under the vehicle floor, a common way to support the fuel pipes and coolant pipes is to support them with the vehicle frame. However, considering safety, it is necessary to bend the rods or the like that that support the fuel pipes and coolant pipes so that the tips of the rods do not point toward the battery pack, which necessitates reducing the mounting space for the battery pack.

[0006] In view of these circumstances, the present invention aims to provide a piping support structure that can maximize the mounting space for battery packs. [Means for solving the problem]

[0007] The present invention provides a structure in which a battery pack for generating driving force, installed under the floor of a vehicle, supports piping extending in the longitudinal direction of the vehicle, wherein the piping is supported by the battery pack via a support member.

[0008] With this configuration, it is only necessary to manage the relative positional variation between the battery pack and the piping, making it possible to maximize the mounting space for the battery pack.

[0009] Incidentally, in a configuration where the battery pack and piping are attached to the vehicle frame separately, it is necessary to manage the relative positional variations between the vehicle frame and the battery pack, and the relative positional variations between the vehicle frame and the piping, and therefore the mounting space for the battery pack needs to be reduced.

[0010] Compared to such configurations, the above-described configuration of the present invention makes it possible to maximize the effective use of the battery pack mounting space under the vehicle floor, which in turn is advantageous in improving the capacity of the battery pack to be installed.

[0011] By the way, in the above-mentioned support structure for the piping, the support member may be configured to include a first rod attached to the battery pack side, a second rod attached to the piping side, and a hanger connecting the first rod and the second rod, wherein the first rod is positioned such that its longitudinal direction is parallel or substantially parallel to the mounting surface to the battery pack.

[0012] With this configuration, in the event of a vehicle collision, the first rod is less likely to collide with the mounting surface of the battery pack. Furthermore, even if the first rod does collide with the mounting surface, the tip of the first rod will not make contact at a single point, but rather the side surface of the first rod will make contact along a line or surface, thereby reducing damage to the battery pack.

[0013] Furthermore, in the support structure for the piping described above, the second rod can be positioned below the first rod, with its longitudinal direction being parallel or substantially parallel to the first rod.

[0014] With this configuration, in the event of a vehicle collision, the second rod is less likely to come into contact with the battery pack.

[0015] Also, According to the present invention Pipe support structure This structure is such that a battery pack for generating driving force, installed under the floor of the vehicle, supports piping extending in the longitudinal direction of the vehicle, and the piping is supported by the battery pack via a support member.The support member includes a front support member for supporting the battery pack in the area of ​​the piping closer to the front of the vehicle, and a rear support member for supporting the battery pack in the area of ​​the piping closer to the rear of the vehicle. The front support member comprises a first front rod attached to the battery pack side, a second front rod attached to the piping side, and a front hanger connecting the first front rod and the second front rod. The rear support member comprises a first rear rod attached to the battery pack side, a second rear rod attached to the piping side, and a rear hanger connecting the first rear rod and the second rear rod. At least one of the second front rod and the second rear rod is positioned so as not to overlap the battery pack in the vertical direction when viewed from at least one of the vehicle's longitudinal direction and vehicle width direction. It is characterized by ru.

[0016] With this configuration, the piping is supported at two points in the longitudinal direction of the vehicle, improving the support rigidity and attitude stability of the piping. In addition, in the event of a vehicle collision, at least one of the second front rod and the second rear rod is less likely to come into contact with the battery pack.

[0017] Also, According to the present invention Pipe support structure This structure is such that a battery pack for generating driving force, installed under the floor of the vehicle, supports piping extending in the longitudinal direction of the vehicle, and the piping is supported by the battery pack via a support member. The support member includes a front support member for supporting the battery pack in the area of ​​the piping closer to the front of the vehicle, and a rear support member for supporting the battery pack in the area of ​​the piping closer to the rear of the vehicle, wherein the front support member comprises a first front rod attached to the battery pack side, a second front rod attached to the piping side, and a front hanger connecting the first front rod and the second front rod, and the rear support member comprises a first rear rod attached to the battery pack side, a second rear rod attached to the piping side, and a rear hanger connecting the first rear rod and the second rear rod, wherein at least one of the first front rod and the first rear rod is attached to the corner of the battery pack. It is characterized by ru.

[0018] According to this configuration, since the corners of the battery pack have relatively high strength, even if a collision load is input to at least one of the first front rod and the first rear rod in the event of a vehicle collision, the corners of the battery pack are less likely to deform.

Effect of the Invention

[0019] According to the present invention, it is possible to provide a pipe support structure that can expand the mounting space of the battery pack as much as possible.

[Figure 2] It is a perspective view showing an enlarged view of the area surrounded by the dashed-dotted line in FIG. 1 from the direction of arrow (2). [Figure 3] It is a perspective view showing an enlarged view of the area surrounded by the dashed-dotted line in FIG. 1 from the direction of arrow (3).

Mode for Carrying Out the Invention

[0021] Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

[0022] An embodiment of the present invention is shown in FIGS. 1 to 3. As shown in these figures, under the floor panel 1 serving as the floor of a vehicle such as an automobile, a battery pack 2 and an exhaust pipe 3 serving as a pipe are installed.

[0023] The battery pack 2 is installed in an area intermediate in the vehicle front-rear direction and the vehicle width direction on the lower surface of the vehicle floor panel 1.

[0024] When viewed from below, the front half of this battery pack 2 is formed in a substantially trapezoidal shape and the rear half is formed in a rectangular shape.

[0025] The battery pack 2, with its shape, has six corners, each equipped with mounting pieces that protrude outward from the floor panel 1. Note that Figure 1 only shows the mounting piece 21 at the right middle corner and the mounting piece 22 at the right rear corner.

[0026] The exhaust pipe 3 is installed on the underside of the vehicle's floor panel 1, in the area between the left-side floor member 4 and the battery pack 2, running from front to rear.

[0027] This exhaust pipe 3 has a catalyst (for example, a three-way catalyst with a filter) 31 on the upstream side in the direction of exhaust gas flow, and a silencer 32 is provided downstream of the catalyst 31 in the direction of exhaust flow.

[0028] In the exhaust pipe 3, the first intermediate pipe 33 downstream of the catalytic converter 31 is supported on the right front side of the battery pack 2 via a front support member 5.

[0029] Furthermore, in the exhaust pipe 3, the second intermediate pipe 34 downstream of the silencer 32 is supported at the right rear corner of the battery pack 2 via a rear support member 6, thereby suspending the exhaust pipe 3 below the floor panel 1.

[0030] The front support member 5 comprises a first front rod 51, a second front rod 52, and a front hanger 53.

[0031] As shown in Figure 2, the base end of the first front rod 51 is attached to the mounting piece 21 at the right middle corner of the battery pack 2 by, for example, a bolt 7.

[0032] The longitudinal direction of the first front rod 51 is positioned so as to be parallel or nearly parallel to the right front slope 23 of the battery pack 2, and the tip of the first front rod 51 is directed toward the center in the vehicle width direction at the front of the vehicle.

[0033] The base end of the second front rod 52 is attached to the first intermediate pipe 33 of the exhaust pipe 3, for example, by welding.

[0034] The longitudinal direction of the second front rod 52 is positioned parallel or approximately parallel to the longitudinal direction of the first front rod 51, and the tip of the second front rod 52 is directed towards the center of the vehicle width direction at the front of the vehicle. Furthermore, the second front rod 52 is positioned below the first front rod 51 in a non-contact manner.

[0035] The front hanger 53 is a hanger, or whatever you might call it, that connects the first front rod 51 and the second front rod 52, and is made of an elastic material such as rubber.

[0036] The front hanger 53 is formed, for example, in the shape of an elliptical column, and holes 54, 54 are provided on both sides of its central axis, passing through along the central axis. The first front rod 51 is inserted into one of these two holes 54, 54, and the second front rod 52 is inserted into the other, so that the relative positions of the first front rod 51 and the second front rod 52 are maintained. The insertion direction of the first front rod 51 and the insertion direction of the second front rod 52 are the same.

[0037] The rear support member 6 comprises a first rear rod 61, a second rear rod 62, and a rear hanger 63.

[0038] As shown in Figure 3, the base end of the first rear rod 61 is attached to the mounting piece 22 at the right rear corner of the battery pack 2 by, for example, a bolt 8.

[0039] The longitudinal direction of the first rear rod 61 is positioned so that it is parallel or nearly parallel to the rear surface of the battery pack 2 (the surface along the vehicle width direction), and the tip of the first rear rod 61 is pointed outwards to the right of the vehicle.

[0040] The second rear rod 62 is attached to the second intermediate pipe 34 of the exhaust pipe 3, for example, by welding, at its base end.

[0041] The longitudinal direction of the second rear rod 62 is positioned parallel or approximately parallel to the longitudinal direction of the first rear rod 61, and the tip of the second rear rod 62 is directed inward towards the vehicle. Furthermore, the second rear rod 62 is positioned below the first rear rod 61 in a non-contact manner.

[0042] The rear hanger 63 is a hanger, or whatever you might call it, that connects the first rear rod 61 and the second rear rod 62, and is made of an elastic material such as rubber.

[0043] The rear hanger 63 is formed in a columnar shape, for example, with an elliptical cross-section, and holes 64, 64 are provided on both sides of its central axis, passing through along the central axis. The first rear rod 61 is inserted into one of these two holes 64, 64, and the second rear rod 62 is inserted into the other, so that the relative positions of the first rear rod 61 and the second rear rod 62 are maintained. Note that the insertion direction of the first rear rod 61 and the insertion direction of the second rear rod 62 are opposite.

[0044] Furthermore, the first front rod 51, the second front rod 52, the first rear rod 61, and the second rear rod 62 are arranged so that they do not overlap with the battery pack 2 in the vertical direction when viewed from the front-rear direction of the vehicle or from the width direction of the vehicle.

[0045] As described above, according to the embodiment to which the present invention is applied, it is only necessary to manage the relative positional variation between the battery pack 2 and the exhaust pipe 3, making it possible to maximize the mounting space for the battery pack 2.

[0046] Incidentally, although not shown in the diagram, in a configuration where the battery pack 2 and the exhaust pipe 3 are mounted separately to the vehicle frame, it is necessary to manage the relative positional variations between the vehicle frame and the battery pack 2, and the relative positional variations between the vehicle frame and the exhaust pipe 3, and therefore the mounting space for the battery pack 2 needs to be reduced.

[0047] Compared to such configurations, the above-described configuration of this embodiment makes it possible to maximize the effective use of the mounting space for the battery pack 2 on the underside of the vehicle's floor panel 1, and consequently, is advantageous in improving the capacity of the battery pack 2 to be mounted.

[0048] Furthermore, in the above embodiment, the exhaust pipe 3 is supported by the battery pack 2 at two points in the vehicle's longitudinal direction via the front support member 5 and the rear support member 6, thereby improving the support rigidity and attitude stability of the exhaust pipe 3.

[0049] Furthermore, in the above embodiment, the longitudinal direction of the first front rod 51 is positioned parallel or approximately parallel to the right front slope 23 of the battery pack 2, and the second front rod 52 is positioned parallel or approximately parallel to the first front rod 51 and positioned below the first front rod 51 in a non-contact manner. Therefore, in the event of a vehicle collision, the second front rod 52 is less likely to collide with the right front slope 23 of the battery pack 2. Moreover, even if the second front rod 52 does collide with the right front slope 23, the tip of the second front rod 52 will not make contact at a point, but rather the side surface of the second front rod 52 will make contact along a line or surface, thereby reducing damage to the battery pack 2.

[0050] Furthermore, in the above embodiment, the longitudinal direction of the first rear rod 61 is positioned parallel or approximately parallel to the rear surface of the battery pack 2, and the second rear rod 62 is positioned parallel or approximately parallel to the first rear rod 61 and positioned below the first rear rod 61 in a non-contact manner. Therefore, in the event of a vehicle collision, the second rear rod 62 is less likely to collide with the rear surface of the battery pack 2. Moreover, even if the second rear rod 62 does collide with the rear surface of the battery pack 2, the tip of the second rear rod 62 will not make contact at a point, but rather the side surface of the second rear rod 62 will make contact along a line or surface, thereby reducing damage to the battery pack 2.

[0051] Furthermore, in the above embodiment, the second front rod 52 and the second rear rod 62 are arranged so that they do not overlap with the battery pack 2 in the vertical direction when viewed from at least one of the vehicle's longitudinal direction and vehicle width direction. Therefore, in the event of a vehicle collision, the second front rod 52 and the second rear rod 62 are less likely to come into contact with the battery pack 2.

[0052] Furthermore, in the above embodiment, the base end of the first front rod 51 is attached to the mounting piece 21 at the right front middle corner of the battery pack 2, which has relatively high strength. Therefore, in the event of a vehicle collision, even if a collision load is applied to the first front rod 51, the right rear corner of the battery pack 2 is less likely to deform.

[0053] Furthermore, in the above embodiment, the base end of the first rear rod 61 is attached to the mounting piece 22 at the right rear corner of the battery pack 2, which has relatively high strength. Therefore, in the event of a vehicle collision, even if a collision load is applied to the first rear rod 61, the right rear corner of the battery pack 2 is less likely to deform.

[0054] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate within the scope of the claims and equivalents thereof.

[0055] (1) In the above embodiment, an exhaust pipe 3 is given as an example of piping, but the present invention is not limited to this. For example, although not shown in the figures, brake piping or a battery pack wire harness can be used as piping.

[0056] (2) In the above embodiment, an example is given in which the exhaust pipe 3 is supported by using two members, a front support member 5 and a rear support member 6, but the present invention is not limited to this.

[0057] For example, although not shown in the diagram, it is possible to support the exhaust pipe 3 by using only one of the front support member 5 and the rear support member 6. Alternatively, it is possible to support the exhaust pipe 3 by using not only the front support member 5 and the rear support member 6, but also one or more additional support members with similar configurations. In the latter configuration, the support rigidity of the exhaust pipe 3 is further improved compared to the above embodiment. [Industrial applicability]

[0058] The present invention can be suitably used in support structures for piping. [Explanation of symbols]
