Description

  The present invention relates to an arrangement structure of a power storage device mounted on a vehicle.

  Conventionally, it is known to mount a power storage device that stores electricity such as a secondary battery (for example, a nickel metal hydride secondary battery, a nickel cadmium secondary battery, a lithium ion secondary battery, or a lead storage battery) on a vehicle such as an automobile. ing. As this power storage device, it is also known that a capacitor is used in addition to the secondary battery.

  The power storage device as described above is often disposed in an engine room or a motor room (when a motor for driving an electric vehicle is disposed), but the power storage device (particularly a capacitor) has heat resistance. Since it is not high, it is placed in the engine room where the temperature is as low as possible. Therefore, for example, Patent Document 1 discloses disposing a power storage device on the front side frame outside front portion of the front side frame.

  By the way, in consideration of the vehicle performance (steerability and turning performance), it is desirable that the heavy object is disposed as close to the center of gravity of the vehicle as possible, especially the wheelbase between the front wheels and the rear wheels. It is preferable that it is disposed inside. Therefore, the structure as in Patent Document 1 in which the power storage device, which is a heavy object, is disposed at the front end of the front side frame has room for improvement for vehicles that require high exercise performance.

  Therefore, the inventor of the present application considers that the power storage device is disposed at the rear position of the front tire in order to dispose the power storage device in the wheel base. However, since the vehicle body wall surface behind the front tire is inclined or curved forwardly from the rear side of the vehicle along the front tire, there are the following problems when the power storage device is provided.

  That is, when the power storage device is attached to the vehicle body wall surface, a mounting bracket is provided on the power storage device. For example, when a bracket extending right above is provided on the rear side (the vehicle rear side) of the power storage device. The bracket is likely to be shortened, and it is difficult to perform the fixing operation because it is hidden behind the power storage device. On the other hand, when a bracket extending right above the power storage device is provided, the workability is relatively good, but the bracket is easy to lengthen, and the entire power storage device including the bracket is increased in size, weight, and cost. Will be promoted. Furthermore, since the power storage device is heavy, it takes a lot of labor for an operator to fix the power storage device to a specific position on the vehicle body wall surface while supporting the power storage device with one hand.

  In order to stably fix the power storage device to the vehicle body wall surface, it is necessary to fix the lower side to the vehicle wall surface via the bracket as well as the upper side of the power storage device. In this case, from the viewpoint of improving the vehicle performance, it is desirable to install the power storage device low to lower the center of gravity of the vehicle. However, the power storage device is installed low and a bracket is provided below the power storage device. In this case, it is difficult to fix the bracket.

In addition, by removing the dividing portion, the entire power storage device 40 is exposed to the front tire 5 side, and the power storage device 40 can be attached and detached.

  As mentioned above, although the vehicle 1 to which the arrangement | positioning structure of the electrical storage apparatus which concerns on this invention was applied was demonstrated, this vehicle 1 has the following advantages.

  First, when assembling the power storage device 40 to the vehicle body, as described above, the hook 58 formed in the first upper fixing portion 54a is locked in the locking hole 72 of the front inner panel 26 to fix the second upper fixing. If the welt bolt 74 is inserted into the through hole 57b of the portion 54b, the upper fixing portions 54a and 54b and the lower fixing portion 61 are fixed in a state where the power storage device 40 is suspended from the front inner panel 26 (temporary deposit state). It can be performed. Therefore, the worker does not need to support the weight of the power storage device 40. In addition, each of the upper fixing portions 54a and 54b has good workability because the bolt B1 and the nut N1 can be fastened almost horizontally from the front side of the vehicle. Further, each upper fixing portion 54a, 54b is provided so as to rise above the power storage device main body 42 at a position between the front end portion and the rear end portion of the power storage device main body 42, so that the size is extremely increased. In addition, there is no inconvenience that it is difficult to perform the fixing work behind the power storage device main body 42. That is, since the front inner panel 26 that is the mounting wall surface of the power storage device 40 is curved forwardly upward along the front tire 5, if an upper fixing portion is provided at the front end portion of the power storage device main body 42, the vertical direction thereof The size is increased and the power storage device 40 is increased in size. Conversely, if the upper fixing portion is provided at the rear end portion of the power storage device main body 42, the vertical dimension of the upper fixing portion is shortened so that it can be easily hidden from the power storage device main body 42, and the upper fixing portion is fixed. May be difficult. However, according to the structure of the vehicle 1, there is no such inconvenience.

  Further, the lower fixing portion 61 extends downward from the rear side of the power storage device main body 42 along the front inner panel 26, and can be fixed to the front inner panel 26 from the front side of the vehicle and obliquely downward (FIG. 3). It is easy to perform the fixing operation of the lower fixing portion 61. Further, the fixing work of the upper fixing parts 54a and 54b and the lower fixing part 61 can be performed by a series of work from the front side of the vehicle.

  Therefore, according to the arrangement structure of the power storage device 40 of the vehicle 1, the bracket 50 (the upper fixing portions 54 a and 54 b) is suppressed from being enlarged, and the power is stored in a compact and stable manner behind the front tire. The device 40 can be arranged, and the assembly workability of the power storage device 40 can be kept good.

  In the vehicle 1, as described above, the upper fixing portions 54a and 54b can be fixed while the power storage device 40 is suspended from the front inner panel 26 (temporary deposit state). As described above, the power storage device 40 is configured such that its center of gravity is positioned between the upper fixing portions 54a and 54b in the vehicle front-rear direction and the vehicle width direction, so that it is unlikely to swing in the suspended state. . Moreover, since each upper side fixing | fixed part 54a, 54b is given the reinforcement structure as mentioned above and the rigidity is improved (refer FIG. 8), it is hard to produce a deformation | transformation. Therefore, there is an advantage that the power storage device 40 can be fixed while the power storage device 40 is stably supported with respect to the front inner panel 26.

  The power storage device 40 is fixed to a portion of the front inner panel 26 that forms a closed cross section. Specifically, each of the upper fixing portions 54a and 54b is fixed to a portion of the front inner panel 26 that forms the laterally extending portion 12c of the front side frame 12, and the lower fixing portion 61 is fixed to the front inner panel 26. The torque box 11 is fixed to a part forming the torque box 11. Therefore, the support rigidity of the power storage device 40 can be ensured satisfactorily (can be firmly fixed to the front inner panel 26). In addition, when the power storage device 40 is fixed to the front inner panel 26 (temporarily deposited) by fixing the power storage device 40 to a highly rigid portion that forms a closed section of the front inner panel 26, the front There is also an advantage that the inner panel 26 can be prevented from being deformed, whereby the power storage device 40 can be fixed to the front inner panel 26 in a stably supported state.

  In the vehicle 1, as shown in FIG. 3, the first upper fixed portion 70 a (the position at which the first upper fixing portion 54 a is fixed) in the region of the front inner panel 26 to which the power storage device 40 is fixed. ) When viewed from the side of the vehicle, the vehicle rear side portion is a predetermined concentric circle sharing the center with the front tire 5 and is offset to the vehicle rear side from the concentric circle C passing through the first upper fixed portion 70a. ing. Therefore, according to the vehicle 1, there is an advantage that the power storage device 40 can be compactly disposed behind the front tire 5 while appropriately securing a necessary space (wheel arch) around the front tire 5.

  Incidentally, the vehicle 1 described above is an example of a preferred embodiment of a vehicle to which the power storage device arrangement structure according to the present invention is applied. The power storage device 40 and its specific arrangement structure are the same as those of the present invention. Changes can be made as appropriate without departing from the scope of the invention.

  For example, as the mounting bracket for the power storage device 40, a bracket 80 as shown in FIGS. 9A and 9B can be applied in addition to the bracket 50 shown in FIGS. Hereinafter, the configuration of the bracket 80 will be briefly described.

  The bracket 80 includes a protective cover 81a covering the front side (front tire side) of the power storage device main body 42, a bracket main body 81b covering the rear side of the power storage device main body 42, and the protective cover 81a and the bracket main body above the power storage device main body 42. And a reinforcing bracket 81c that connects 81b. In the bracket 80, a first upper fixing portion 84a, a second upper fixing portion 84b, and a lower fixing portion 87 are formed on the bracket main body 81b that covers the rear side of the power storage device main body 42. Each of these upper fixing portions 84a, 84b and lower fixing portion 87 is configured substantially the same as each upper fixing portion 54a, 54b and lower fixing portion 61 of bracket 50 of power storage device 40 shown in FIGS. The first upper fixing portion 84a is provided with a fastening through hole 85a and a hook 86 at the tip thereof, and the second upper fixing portion 84b and the lower fixing portion 88 are each provided with a fastening through hole 87b at the tip thereof. 88. The upper fixing portions 84a and 84b of the bracket 80 are not provided with a reinforcing structure (see FIG. 8) like the upper fixing portions 54a and 54b of the bracket 50, but the upper fixing portions of the bracket 80 are not provided. 84a and 84b are preferably provided with the same reinforcing structure.

  In the power storage device 40 of the above embodiment, the hook 58 provided on the first upper fixing portion 54a of the bracket 50 is locked to the locking hole 72, and the welt bolt 74 is inserted into the through hole 57b of the second upper fixing portion 54b. By inserting, the power storage device 40 is configured to be supported by the front inner panel 26 in a suspended state, but the second upper fixing portion 54b is similar to the first upper fixing portion 54a. A hook may be formed on the upper fixing portion 54b to be locked in a locking hole provided in the front inner panel 26. Conversely, the hook 58 of the first upper fixing portion 54a may be omitted, and a welt bolt provided on the front inner panel 26 may be inserted into the through hole 57a. That is, the locking structure of the upper fixing portions 54a and 54b to the front inner panel 26 may be made common. However, when the locking structure of the upper fixing parts 54a and 54b is unified to a structure using a hook, it is necessary to work while adjusting the positions of the upper fixing parts 54a and 54b at the time of bolt fastening. The work may be complicated because there are. On the other hand, when the locking structure of the upper fixing portions 54a and 54b is unified to a structure using a welt bolt, it is necessary to insert the welt bolt into both the upper fixing portions 54a and 54b at the same time. Become. On the other hand, according to the structure of the above embodiment, the hook 58 of the first upper fixing portion 54a may be inserted into the locking hole 72 with the welt bolt 74 inserted into the second upper fixing portion 54b. Work is easy. Further, when fastening bolts or the like, only the first upper fixing portion 54a needs to be aligned, so that workability is good. Therefore, it is considered that the power storage device 40 can be assembled to the vehicle body more smoothly than in the case where the locking structure of the upper fixing portions 54a and 54b to the front inner panel 26 is made common. As for the locking structure of the second upper fixing portion 54b, as described above, the nut N1 is attached to the welt bolt 74 inserted into the through hole 57b, so that the second upper fixing portion 54b is directly attached to the front inner panel. According to such a configuration, the welt bolt 74 combines the function of the member for fixing the second upper fixing portion 54b to the front inner panel 26 and the locked portion of the present invention. Therefore, there is an advantage that a rational configuration is achieved.

  In addition, although two upper fixing portions 54a and 54b are formed in the bracket 50 of the power storage device 40, the number of the upper fixing portions may be one, or may be three or more. In addition, one lower fixing portion 61 is formed in the bracket 50, but the number of lower fixing portions may be two or more.

  Note that the present invention can be applied to an electric vehicle or a hybrid vehicle equipped with a traveling motor in addition to the vehicle that travels using the engine body 3 as a drive source as described above.
