Description

  The present invention relates to an air cleaner mounting structure for a vehicle.

  A vehicle (automobile) has an engine room in the front, and an engine, an air cleaner, a battery, and the like are arranged in the engine room. The air cleaner and the battery are essential components for the internal combustion engine, and various layouts are provided for their arrangement. As an example, Patent Document 1 discloses that an air cleaner is disposed above an engine (engine body), while a battery is disposed on the left side of the engine when viewed from a driver.

JP 2009-57951 A

  It can be said that the air cleaner and the battery each have a high degree of freedom in arrangement positions, and the positions are designed in consideration of the arrangement of other members. In Patent Document 1, the air cleaner is disposed above the engine. However, this configuration has a problem that the height of the hood (bonnet) is increased.

  Therefore, the air cleaner may be arranged on the left side or the right side of the engine for reasons such as a limitation on the height of the engine room. In this case, the battery may have to be arranged behind the air cleaner. In this case, there is no particular problem with the function of the air cleaner and the battery, but if the vehicle crashes, the air cleaner moves backward and hits the battery severely, causing damage to the battery and leakage of battery fluid. It is feared that it will.

  Since the battery liquid is strongly acidic, if it leaks, it takes a lot of trouble to deal with the accident, and may cause a danger to the operator. Therefore, even if a collision accident occurs, leakage of the battery fluid should be prevented.

  The present invention has been made in view of such circumstances, and provides a technology that can prevent or minimize damage to a battery even if a collision accident occurs when an air cleaner and a battery are arranged side by side. It is something you want to do.

The present invention is
`` In an engine room provided in the front part of the vehicle body, an air cleaner and a battery are arranged side by side so that the air cleaner is located in front, and the air cleaner is provided with a lower support member arranged thereunder, It is attached to the front frame material located at the front. ''
In the basic configuration of
"The air cleaner is supported by the lower support member by locking means so that it cannot be disengaged in the horizontal direction and can be detached upward.
The front frame member is fixed via a front bracket that is inclined in a plan view with respect to the front-rear longitudinal line of the vehicle body, and the front bracket is arranged so that an extension of the front bracket does not pass through the battery. ing"
It has the feature of.

  In the present invention, that the air cleaner can be detached upward means that the air cleaner can be detached upward when a rearward external force of a certain degree or more acts upon a collision accident. Therefore, it also includes detachment due to deformable damage of the member.

  In the present invention, the air cleaner can be supported by the locking means at only one location with respect to the lower support member, but is preferably supported at a plurality of locations from the viewpoint of stability. In particular, when supported at two places on the left and right as in the embodiment, since the left and right locking means and the front bracket at the front provide a three-point support state, an advantage that a high stability can be ensured despite a simple configuration. There is.

  In the present invention, in a normal state, the air cleaner is supported by the lower support member and the front frame member, so that its function is not hindered. Naturally, the battery also plays a role without any problem.

  On the other hand, when a large rearward external force acts on the air cleaner due to a collision accident, the battery is pushed rearward through the front bracket, but since the air cleaner can be separated upward from the lower support member, the air cleaner is disengaged from the lower support member. It disengages upward and moves backward by the pushing action of the front bracket.

  Since the front bracket is inclined in a plan view, the front frame member tends to be pushed in the direction of the extension of the front bracket, but since the extension of the front bracket does not pass through the battery, the air cleaner and the front bracket are not provided. Will travel behind the side of the battery. Therefore, it is possible to prevent the air cleaner and the front bracket from hitting the battery, or even if it hits the battery, the impact is remarkably reduced. Therefore, it is possible to prevent a situation in which the battery case is damaged and battery liquid leaks.

  More specifically, since the front bracket is inclined in plan view, when the air cleaner is pushed backward by the front bracket, the air cleaner tends to move backward while turning in plan view, so even if the air cleaner hits the battery. The air cleaner will run backwards and hit the battery, so that only a small fraction of the kinetic energy of the air cleaner will act on the battery. As a result, it is possible to securely prevent the battery from being damaged and the battery fluid from leaking.

It is a top view of an embodiment. It is an enlarged plan view of a principal part. (A) is a sectional view taken along the line IIIA-IIIA of FIG. 2, (B) is a sectional view taken along the line IIIB-IIIB of FIG. 2, and (C) is a sectional view taken along the line IIIC-IIIC of FIG. It is a schematic diagram which shows the effect | action at the time of a collision.

  Next, an embodiment of the present invention will be described with reference to the drawings. In the following, front / rear / left / right words are used to specify the direction, but this direction is defined as the direction viewed from the driver. Therefore, the front-back direction is the longitudinal direction of the vehicle, and the left-right direction is the width direction of the vehicle. For clarity, the directions are clearly shown in FIGS.

(1). Structure of the embodiment As schematically shown in FIG. 1, an engine (engine body) 2 of an internal combustion engine is placed horizontally in an engine room 1 provided at a front portion of a vehicle body with a crankshaft in a left-right longitudinal posture. It is arranged in. The engine main body 2 has an exhaust side on the front side and an intake side on the rear side.

  An air cleaner 3 is disposed at the front of the engine room 1 and to the left of the engine 2, and a battery 4 is disposed immediately behind the air cleaner 3. The lower surface of the air cleaner 3 and the lower surface of the battery 4 are approximately the same height.

  As shown in FIG. 3A, the lower part of the air cleaner 3 is a dust chamber 3a and the upper part is a clean chamber 3b. The upper part of a front chamber 3c provided at the front of the dust chamber 3a is shown in FIGS. The intake duct 5 shown in FIG. The start end of the first intake hose 6 is connected to the clean chamber 3b of the air cleaner 3. The end of the first intake hose 6 is connected to the inlet port of the compressor housing in the exhaust turbocharger.

  Although not shown, a start end of a second intake hose is connected to an outlet port of the compressor housing in the exhaust turbocharger. In FIG. 1, reference numeral 7 denotes a third intake hose having a start end connected to the outlet of the intercooler, and an end of the third intake hose 7 connected to a throttle body (not shown).

  As shown in FIG. 2, a lower support member 8 that supports a rear portion of the air cleaner 3 is disposed in a portion of the engine room 1 that is located behind the air cleaner 3. As shown in FIGS. 3 (A) and 3 (C), the lower support member 8 has, for example, a groove shape opened downward and has a left and right longitudinal posture, and two left and right portions of the dust chamber 3a of the air cleaner 3 are provided. It is attached to the lower support member 8 by pin locking, which is an example of the locking means described in the claims.

  That is, as clearly shown in FIG. 3 (C), a downward pin 10 is integrally provided in the dust chamber 3a of the air cleaner 3, and a rubber grommet 11 is attached to the lower support member 8 so as not to fall off. A hole 12 is provided, and the pin 10 is closely fitted to the grommet 11 from above. Therefore, the air cleaner 3 is attached to the lower support member 8 so that it cannot be displaced in the horizontal direction and can be detached upward.

  At the front of the vehicle body and in front of the air cleaner 3, there is arranged an radiator support 13 to which an upper part of a radiator (and a condenser for air conditioner, none of which is shown) is attached. The upper radiator support 13 is an example of the front frame member described in the claims, and has a form of a channel member that opens downward as can be understood from FIG.

  The right end of the front chamber 3 c of the air cleaner 3 is fixed to the radiator support 13 via the front bracket 14. The front bracket 14 is made of a strip, and the front end is fixed to the upper radiator support 13 by one front bolt 15, and the rear end is fixed to the upper surface of the front chamber 3 c of the air cleaner 3 by one rear bolt 16. Have been. Since the front chamber 3c of the air cleaner 3 is slightly lower than the applicator support 13, the front bracket 14 is bent stepwise (in a crank shape) in a side view so that the front part is high and the rear part is low. I have.

  As shown in FIGS. 1 and 2, the front bracket 14 is inclined with respect to the longitudinal line 17 of the vehicle body so as to shift toward the center of the vehicle body toward the rear (to shift rightward). The inclination angle θ is set to an angle at which the extension line 18 does not pass through the battery 4.

  Note that the intake duct 5 of the air cleaner 3 is L-shaped in plan view, and its front end is open downward toward the support radiator 13. Therefore, the air is sucked upward by the intake duct 5 and then reaches the dust chamber 3a via the front chamber 3c.

  As shown in FIG. 3B, the battery 4 is placed on the receiving base 19 so as not to be displaced, and is held by a holding member such as a belt 20 so as not to fall off. In FIG. 1, reference numeral 21 denotes a front bumper, and reference numeral 22 denotes a feed pipe for sending cooling water to an upper tank of a radiator.

(2). Conclusion As shown in FIG. 4, the vehicle may move forward and collide with the fixed object 23 or another vehicle, or may be hit against another vehicle in a stopped state from the front. In this case, since a rearward impact force acts on the vehicle body, if the impact force is strong to a certain degree or more, the front bumper 21 and the applicator support 13 retreat, and the air cleaner 3 pushes backward through the front bracket 14. Be sent.

  In this case, for example, if the front bracket 14 is fixed to the right and left at two positions with respect to the applicator support 13, the air cleaner 3 retreats without changing its posture as shown by the dotted line in FIG. 4. And hit the battery 4. Then, since the impact force applied to the air cleaner 3 is applied to the battery 4 without being moderated, the case of the battery 4 is damaged (crushed), and the battery liquid (electrolyte) leaks. Is possible.

  On the other hand, in the present embodiment, since the front end of the air cleaner 3 is fixed to the appendage radiator support 13 by the front bracket 14 having the right end inclined, the rearward external force exerted by the accident does not affect the air cleaner 3. On the other hand, it acts as an external force pushing in the direction of the extension of the front bracket 14.

  Then, first, the pin 10 comes out of the grommet 11 due to the lifting of the air cleaner 3 due to the pushing action, the lower support member 8 is deformed, and the pin 10 comes out of the grommet 11, or the pin 10 is broken. The air cleaner 3 is detached from the lower support member 8 while deforming itself. Next, the air cleaner 3 is pushed in the direction of the extension line 18 of the front bracket 14 as shown by a chain line in FIG. Therefore, the air cleaner 3 can retreat without hitting the battery 4. Thereby, the battery 4 can be prevented from being greatly damaged.

  In addition, since the air cleaner 3 receives a pressing action in the inclined direction with respect to the right end thereof in plan view, the air cleaner 3 has a tendency to retreat while turning clockwise in plan view, so that the air cleaner 3 may hit the battery 4. Even so, the air cleaner 3 hits the battery 4 while escaping, so that the impact force acting on the battery 4 is small, and therefore, the battery 4 does not suffer significant damage such as leakage of battery fluid. .

  When the front bracket 14 is connected to the right end of the air cleaner 3 as in the present embodiment, the effect of turning the air cleaner 3 due to the retreat due to the collision of the air cleaner 3 is increased, and the effect of preventing the battery 4 from being damaged can be improved. When the air cleaner 3 is arranged at the right end of the engine room, the front bracket 14 may be connected to the left end of the air cleaner 3 in an inclined posture opposite to that shown in the figure.

  When the pin 10 is inserted into the grommet 11 as the locking means as in the embodiment, when the air cleaner 3 is assembled, the air cleaner 3 can be temporarily held only by inserting the pin 10 into the grommet 11. Has an advantage that the air cleaner 3 can be easily fixed (there is no need to hold and hold the air cleaner 3 by hand).

  In the present embodiment, the front bracket 14 is fixed to the air radiator support 13 and the air cleaner 3 by the bolts 15 and 16 one by one. Can rotate relative to both in plan view. Therefore, it can be said that the effect of pushing the air cleaner 3 to the right side is promoted, which further contributes to the effect of preventing the battery 4 from being damaged.

  Further, when the air cleaner 3 is supported by the rubber grommet 11 as in the embodiment, there is an advantage that vibration and noise can be prevented.

  The present invention can be embodied in various ways in addition to the above embodiment. For example, as a locking means for connecting the air cleaner 3 and the lower support member 8, an upward pin may be provided on the lower support member 8 to form an engagement hole on the lower surface of the air cleaner 3. Also, the front bracket 14 can be fixed to the front frame member only at the front end with a plurality of bolts, or can be fixed at the rear end only to the air cleaner 3 with a plurality of bolts.

  The present invention can be embodied in a vehicle including an air cleaner and a battery. Therefore, it can be used industrially.
