Description

  The present invention provides a dash panel that partitions the vehicle compartment and the engine room in the vehicle front-rear direction, the dash panel being recessed toward the rear of the vehicle, and a dash panel in which a powertrain unit for driving wheels is disposed. The present invention relates to an auxiliary equipment arrangement structure for a vehicle in which an auxiliary equipment such as an air conditioning unit is arranged in a vehicle formed from a central concave portion and dash side portions extending on both sides of the dash central concave portion in the vehicle width direction.

  Conventionally, a power train (engine and transmission) as a heavy object is arranged near the center in the longitudinal direction of the vehicle to reduce the yaw moment of inertia, thereby improving the steering stability and the vehicle performance. There is a structure shown in FIG. In FIG. 9, the configuration when a rotary engine and transmission are used as the power train is shown by a solid line, and the configuration when a reciprocating engine and transmission is used as a power train is shown by a dotted line.

  The conventional structure shown in FIG. 9 is provided with dash panels 100A and 100B that partition the engine room and the vehicle compartment in the front-rear direction. The dash panels 100A and 100B are recessed toward the rear in the center in the vehicle width direction. The rotary engine 102A or the rotary engine 102A that forms the power train in the dash center recesses 101A and 101B is formed by forming recesses 101A and 101B (dash center recesses) and providing dash side portions on both sides of the dash center recess in the vehicle width direction. A part of the rear side of the reciprocating engine 102B is disposed, and transmissions 104A and 104B are disposed below the tunnel portion 103, that is, outside the vehicle, and further in the vehicle width direction so as to be close to the recesses 101A and 101B. Is provided with air conditioning units 105A and 105B as an example of an auxiliary unit for vehicles. Than is.

  In comparison between the solid line (rotary engine mounting form) in FIG. 9 and the dotted line (reciprocating engine mounting form), since the reciprocating engine 102B is larger than the rotary engine 102A, the concave portion 101B of the dash panel 100B is set to that when the rotary engine is mounted. On the other hand, the air conditioning unit 105B that is set further rearward and disposed at the center portion in the vehicle width direction is set to be smaller than the air conditioning unit 105A when the rotary engine is mounted.

  With this configuration, it is possible to reduce the yaw moment of inertia, improve the steering stability, and improve the vehicle performance, regardless of whether the rotary engine 102A or the reciprocating engine 102B is mounted.

  However, further reduction of the yaw moment of inertia and further improvement of steering stability, etc. are demanded. In this case, it is conceivable to move the rotary engine 102A and the reciprocating engine 102B backward further, Since the engine interferes with the air conditioning units 105A and 105B, the backward movement (rear shift layout) is impossible.

Patent Document 1 discloses a structure that is substantially the same as the configuration when the rotary engine 102A of FIG. 9 is mounted.
On the other hand, Patent Document 2 and Patent Document 3 disclose an auxiliary device arrangement structure in which an air conditioning unit for air-conditioning the vehicle interior is arranged at the rear of the vehicle compartment in order to achieve further backward arrangement of the power train. However, since the passenger compartment or the luggage compartment becomes narrow corresponding to the space occupied by the air conditioning unit, there is a problem that is not practical.

In addition, the divided dash side 4 extends in the front-rear direction along the side of the power train 34 and separates the vehicle auxiliary equipment (see the air conditioning unit 60) from the heat-resistant wall (vertical wall 4a). (See FIG. 2).
According to this configuration, heat damage from the power train 34 to the vehicle auxiliary machine (see the air conditioning unit 34) can be reliably prevented by the heat resistant wall (see the vertical wall 4a). Here, it is effective to use a member having high heat resistance as the divided dash side portion 4.

Further, a driver seat 56 and a passenger seat 57 are juxtaposed in the vehicle width direction inside the passenger compartment 2 behind the dash lower panel 3, and a dash side portion (divided dash side) corresponding to the passenger seat 57 side is provided. The vehicle auxiliary machine (see the air conditioning unit 60) is disposed in the section 4) (see FIG. 2).
According to this configuration, it is possible to achieve the layout in the passenger compartment 2, that is, the securing of the living space, the layout of the vehicle auxiliary machine (see the air conditioning unit 60), and the layout in the engine room 1.

Further, the vehicle accessory is an air conditioning unit 60 for the interior of the vehicle compartment 2 (see FIG. 2).
According to this configuration, since the air conditioning unit 60 located between the engine room 1 and the passenger compartment 2 is efficiently disposed, the rear shift layout of the power train 34 can be reduced while suppressing the influence on the passenger compartment 2. The coexistence with the arrangement of the air conditioning unit 60 can be achieved.

In addition, the air conditioning unit 60 includes a heat exchanger unit 65, an air mix unit 63, and a blower unit 64, and the blower unit 64 is disposed on the divided dash side portion 4 side ( (See FIGS. 4 and 5).
According to this configuration, the air conditioning unit 60 can be appropriately laid out while ensuring the air distribution efficiency of the air conditioning air.

Further, behind the blower unit 64, the heat exchanger unit 65 and the air mix unit 63 are arranged side by side in a substantially vehicle width direction (see FIGS. 4 and 5).
According to this configuration, the air conditioning unit 60 including the heat exchanger unit 65, the air mix unit 63, and the blower unit 64 is provided in a limited space between the divided dash side portion 4 side and the passenger compartment 2 side. Can be laid out compactly.

In the correspondence between the configuration of the present invention and the above-described embodiment,
The dash panel of the present invention corresponds to the dash lower panel 3 of the embodiment,
Similarly,
The wheels driven by the powertrain correspond to the rear wheels 38,
The vehicle auxiliary machine corresponds to the air conditioning unit 60,
The heat-resistant wall portion corresponds to the vertical wall portion 4a,
The driver seat corresponds to the driver seat 56,
The passenger seat corresponds to the passenger seat 57,
The present invention is not limited to the configuration of the above-described embodiment.
For example, in the above embodiment, a left-hand drive vehicle is illustrated, but this may be a right-hand drive vehicle, and the vehicle accessory is not limited to an air conditioning unit, but a battery, an ECU (engine control unit), or the like. Other vehicle auxiliary machines may be used.
