Description

  The present invention relates to a vehicle in which a mounted object is attached to a fixed structure fixed in an engine room via a bracket.

  As described in Patent Document 1, an engine, a transmission, and the like are accommodated in the engine room of the vehicle.

JP 7-25353 A

  As shown in FIG. 5, a load may be attached to an engine or transmission that is a fixed structure fixed in the engine room via a bracket 130. FIG. 5 shows a state in which the electromagnetic valve 15 is mounted as a load on the transmission 12 which is one of the fixed structures fixed in the engine room 10.

  By the way, when the vehicle collides and the engine room 10 is deformed, the fixed structure and the dash panel 20 come closer to each other. Therefore, when the mounted object is attached so as to protrude toward the dash panel 20 as shown in FIG. 5, the mounted object and the dash as shown in FIG. 6 in the process of approaching the fixed structure and the dash panel 20. There is a possibility that the panel 20 contacts and the dash panel 20 is deformed by the force received from the mounted object.

  An object of the present invention is to provide a vehicle in which a dash panel is not easily deformed even when the mounted object and the dash panel come into contact with the deformation of the engine room.

  A vehicle for solving the above problems includes a fixed structure fixed next to the dash panel in an engine room separated from the vehicle compartment by a dash panel, a mounted object mounted on the fixed structure, and a metal plate. And a bracket formed by. The bracket is positioned between the first fixing portion and the second fixing portion to which the mounted object is fixed, and the first fixing portion and the second fixing portion, and is fixed to the fixing structure. And a third fixing portion. The mounted object is separated from the fixed structure via the bracket fixed to the fixed structure in a direction in which the first fixed portion is closer to the dash panel than the second fixed portion. It is attached to the fixed structure in a state protruding from the dash panel side. In addition, a bellows portion that is folded back and folded a plurality of times is provided between the second fixing portion and the third fixing portion of the bracket.

As described above, when the vehicle collides and the engine room is deformed, the fixed structure and the dash panel come closer.
On the other hand, in the bracket in said vehicle, the bellows part is provided in the position away from the dash panel rather than the 3rd fixing | fixed part fixed to the fixed structure. Therefore, after the fixed structure and the dash panel come into contact with each other in the process of approaching the fixed structure and the dash panel, the folded portion of the bellows portion develops as the fixed structure and the dash panel further approach each other. It becomes like this. That is, when the mounted object and the dash panel come into contact with each other in the process of approaching the fixed structure and the dash panel, relative movement of the mounted object with respect to the fixed structure is likely to occur.

  Therefore, even if the load and dash panel come into contact with each other in the process of approaching the fixed structure and the dash panel, the force transmitted from the load to the dash panel is reduced by the relative movement of the load with respect to the fixed structure. The deformation of the dash panel is suppressed.

  In other words, according to the above vehicle, even if the mounted object and the dash panel come into contact with the deformation of the engine room, the dash panel is hardly deformed.

The schematic diagram which shows the state in an engine compartment when the solenoid valve and dash panel in the vehicle of a comparative example contact | abut.

  As shown in FIG. 1, an engine room 10 separated from the vehicle compartment 3 by a dash panel 20 is arranged on the front wheel 2 side of the vehicle 1 from the vehicle compartment 3. In the engine room 10 of the vehicle 1, an engine 11 and a transmission 12 that are fixed structures fixed to the vehicle body and that drive the front wheels 2 are accommodated. In this vehicle 1, the transmission 12 is disposed in front of the dash panel 20 in the engine room 10 as shown in FIG. 1. That is, the transmission 12 is disposed next to the dash panel 20.

  A radiator 13 is housed in the engine room 10 of the vehicle 1. The radiator 13 is connected to a plurality of machine elements including the engine 11 via a hose 14. Cooling water that circulates through a plurality of mechanical elements arranged in the engine room 10 including the engine 11 radiates heat by the heat exchange with air in the radiator 13.

  An electromagnetic valve 15 as a load is mounted on the transmission 12 via a bracket 30. A hose 14 is connected to the electromagnetic valve 15 and the flow of the cooling water is controlled by opening and closing the electromagnetic valve 15. Specifically, the electromagnetic valve 15 is closed when the circulation of the cooling water is stopped, and is opened when the cooling water is circulated.

  As shown in FIG. 2, the bracket 30 is formed by bending a metal plate having a longitudinal direction. At one end in the longitudinal direction of the bracket 30, a hole 31A into which a bolt is inserted is provided, and a first fixing portion 31 to which the electromagnetic valve 15 (see FIG. 1) is fixed is formed. A hole 32A into which a bolt is inserted is provided at the other end in the longitudinal direction of the bracket 30, and a second fixing portion 32 to which the electromagnetic valve 15 is fixed is formed. And between the 1st fixing | fixed part 31 and the 2nd fixing | fixed part 32 in the bracket 30, the hole 33A in which a volt | bolt is inserted is provided, and the 3rd fixation fixed to the transmission 12 (refer FIG. 1). A portion 33 is formed.

  Between the second fixing part 32 and the third fixing part 33 in the bracket 30, the metal plate constituting the bracket 30 is folded three times and folded to form a bellows part 34. The strength of the bellows portion 34 is lower than the strength of other portions of the bracket 30.

  As shown in FIG. 3, the bracket 30 is fixed to the transmission 12 by bolts 43. The bracket 30 is fixed to the transmission 12 such that the first fixing portion 31 is closer to the dash panel 20 than the second fixing portion 32.

The electromagnetic valve 15 is fixed to the bracket 30 thus fixed to the transmission 12 by bolts 41 and 42.
Thus, the electromagnetic valve 15 is attached to the transmission 12 via the bracket 30 in a state of protruding from the transmission 12 to the dash panel 20 side.

The operation of the vehicle 1 will be described with reference to FIGS.
When the vehicle 1 (see FIG. 1) collides with an object and the engine room 10 is deformed, the transmission 12 and the dash panel 20 are brought closer. For example, the object is a wall or another vehicle.

  When the vehicle 1 collides and the engine room 10 is deformed, the electromagnetic valve 15 and the dash panel 20 come into contact with each other as shown by a two-dot chain line in FIG. The force that the valve 15 receives from the dash panel 20 is transmitted to the bracket 30.

  The bracket 30 in the vehicle 1 (see FIG. 1) is provided with a bellows portion 34 at a position farther from the dash panel 20 than the third fixing portion 33 fixed to the transmission 12. Therefore, as the transmission 12 and the dash panel 20 are closer, the folded portion of the bellows portion 34 is developed by receiving a force from the dash panel 20 as indicated by a solid line.

  Then, as the bellows portion 34 is deployed, the second fixing portion 32 moves to the front side of the vehicle 1, and the portion of the bracket 30 between the first fixing portion 31 and the third fixing portion 33 is folded back. The first fixing portion 31 also moves to the front side of the vehicle 1. That is, in the vehicle 1, when the electromagnetic valve 15 and the dash panel 20 come into contact with each other in the process in which the transmission 12 and the dash panel 20 approach each other, the electromagnetic valve 15 is likely to move relative to the transmission 12. Yes.

  Therefore, in this vehicle 1, even if the electromagnetic valve 15 and the dash panel 20 come into contact with each other in the process in which the transmission 12 and the dash panel 20 approach each other, the relative movement of the electromagnetic valve 15 with respect to the transmission 12 causes the electromagnetic valve 15 to move away from the electromagnetic valve 15. The force transmitted to the dash panel 20 is alleviated and deformation of the dash panel 20 is suppressed.

  FIG. 5 shows a comparative vehicle in which the electromagnetic valve 15 is attached to the transmission 12 via a bracket 130. The bracket 130 has a configuration in which the bellows portion 34 (see FIG. 2) provided in the bracket 30 (see FIG. 2) is omitted.

  When the vehicle of the comparative example collides and the engine room 10 is deformed, the electromagnetic valve 15 and the dash panel 20 come into contact with each other as shown in FIG. The force received from the dash panel 20 is transmitted to the bracket 130.

  Here, since the bellows portion 34 (see FIG. 2) is not provided in the bracket 130, even if the bracket 130 is deformed by receiving a force from the dash panel 20, the relative movement of the electromagnetic valve 15 with respect to the transmission 12 occurs. Hateful. Therefore, when the electromagnetic valve 15 and the dash panel 20 come into contact with each other in the process in which the transmission 12 and the dash panel 20 approach each other, the force transmitted from the electromagnetic valve 15 to the dash panel 20 is difficult to be reduced. Therefore, in the vehicle of the comparative example, the dash panel 20 may be deformed by the force received from the electromagnetic valve 15 as the engine room 10 is deformed.

That is, according to the vehicle 1 in which the electromagnetic valve 15 is mounted on the transmission 12 via the bracket 30, the following effects can be obtained.
(1) A comparative example in which the electromagnetic valve 15 is mounted on the transmission 12 via the bracket 130 without the bellows 34 even if the electromagnetic valve 15 and the dash panel 20 come into contact with the deformation of the engine room 10. The dash panel 20 is less likely to be deformed as compared to the other vehicle.

  (2) When the strength of the bellows portion 34 is the same as the strength of other portions of the bracket 30 or higher than the strength of other portions, the bracket 30 receives a force from the dash panel 20 as the engine room 10 is deformed. Other parts of the bracket 30 may be deformed before the bellows part 34 is deployed. In this case, the development of the bellows portion 34 may be hindered.

  On the other hand, in the bracket 30 of the vehicle 1, the strength of the bellows portion 34 is lower than the strength of other portions of the bracket 30. Therefore, when the bracket 30 receives a force from the dash panel 20 as the engine room 10 is deformed, the bellows portion 34 is first developed. That is, the development of the bellows portion 34 is not easily disturbed.

  Thus, in the vehicle 1, the bellows portion 34 can be sufficiently developed when the engine room 10 is deformed. Therefore, compared to the case where the strength of the bellows portion 34 is the same as that of the other portion of the bracket 30 or higher than the strength of the other portion, the relative movement amount of the electromagnetic valve 15 with respect to the transmission 12 tends to be large. Therefore, the force transmitted from the electromagnetic valve 15 to the dash panel 20 is easily relaxed, and deformation of the dash panel 20 is further suppressed.

In addition, the said embodiment can also be implemented with the following forms which changed this suitably.
-Although the front wheel drive vehicle which drives the front wheel 2 with the engine 11 and transmission 12 which were accommodated in the engine room 10 was illustrated as the vehicle 1, a rear wheel is driven with the engine 11 and transmission 12 which were accommodated in the engine room 10 The same configuration can also be adopted in a rear wheel drive vehicle that performs the same or a four wheel drive vehicle that drives the front wheels and the rear wheels.

  -As the vehicle 1, the vehicle in which the electromagnetic valve 15 is mounted on the transmission 12, which is one of the fixed structures fixed in the engine room 10 via the bracket 30, is illustrated. The combination with a thing is not limited to the illustrated combination. In other words, the fixed structure only needs to be arranged next to the dash panel 20 in the engine room 10, and the mounted object is fixed so as to protrude from the fixed structure to the dash panel 20 side via the bracket 30. What is necessary is just to be attached to a structure. For example, instead of the transmission 12, the bracket 30 may be fixed to the engine 11 disposed next to the dash panel 20 and the electromagnetic valve 15 may be mounted on the engine 11. Moreover, you may make it mount things other than the solenoid valve 15 as a mounting thing.

-The bellows part 34 should just be the shape folded back and folded in multiple times, and the frequency | count of folding may be 2 times or 4 times or more.
-The structure where the intensity | strength of the bellows part 34 is the same as the intensity | strength of the other part in the bracket 30, or higher than the intensity | strength of another part may be sufficient.

  -The bracket 30 should just be formed with the metal plate, and is not restricted to what forms a metal plate by bending. For example, the bracket 30 made of a plate-like metal bent as shown in FIG. 2 can be formed by casting.
