DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle reserve tank for storing cooling water for an automobile engine.

[0002]

2. Description of the Related Art Conventionally, engines mounted on automobiles include:
A cooling water circulation device that absorbs heat is provided. A reserve tank for storing cooling water is installed in an engine room or the like, and an inlet is usually provided on an upper surface of the reserve tank to supply cooling water.

A reserve tank 1 shown in FIGS. 9 to 12 has an inlet 2 opened upward on the upper surface and a cap 4 having two pipes 3 fitted therein (see FIG. 61-7).
No. 2427 and Japanese Utility Model Laid-Open No. 57-59121). The pipe 3 is oriented horizontally, and a drain tube 5 is connected to one pipe 3. The other pipe 3
Is open to the atmosphere. Japanese Utility Model Application Laid-Open No. 61-17131 discloses that a reserve tank is provided with an air opening opening obliquely upward. In addition, there is also a reserve tank with a structure in which the cap and pipe are separated as described above (see Japanese Utility Model Laid-Open No. 62-95125). In this structure, an air vent tube is provided obliquely downward at the neck of the inlet. Things.

[0004] The drain tube 5 connected to the pipe 3 is configured to allow overflowing cooling water to flow and to prevent cooling water from flowing to other members.

In the reserve tank 1 shown in FIG. 9 and those disclosed in the publication, the opening of the injection port is directed upward, so that the cooling water is easily injected into the engine room. Also figure
As shown in FIG. 12, an annular projection 4a is formed at the tip of the cap 4, and an annular projection 2a formed at the inlet 2 is formed. I have. Reference numeral 6 denotes a packing.

[0006]

By the way, in order to allow the overflowed cooling water to flow to the outside, a drain tube 5 is required.
Is connected to the pipe 3, but a space for connection work is required, and the drain tube 5 needs to be clamped to the vehicle body side. Further, since many other parts are stored in the engine room, it is necessary to lay out the other parts so that cooling water does not splash on them.

When the cap 4 is mounted, the projection 4a of the cap 4 is aligned with the injection port 2 and then pressed from above to fit the same. Sometimes it shifts,
It is troublesome to cover the cap 4.

SUMMARY OF THE INVENTION An object of the present invention is to provide a reserve tank for a vehicle which can easily treat overflowed cooling water and can be easily covered with a cap.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a vehicle having a tank body and a cylindrical neck.
In a reserve tank, the tank body is connected to the neck.
A mounting bracket provided on the opposite side;
Attach the tank body to the side member by attaching a
It is arranged in the gap between the id member and the radiator, and the neck is
Move away from the upper surface of the tank body and the side members
So that the bumper and engine
Through the gap between the radiator and
It is characterized by being located on the side .

[0010]

[0011]

[0012]

Since the present invention is constructed as described above, the neck is positioned in front of the radiator through the gap, and
Attach the body to the side members outside the engine compartment
Thus, there is room in the engine room.

[0013]

[0014]

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the vehicle reserve tank according to the present invention has an inlet 2 formed obliquely upward from a tank body 7, and the inlet 2 is extended upward from a top surface 7 a by a neck 8. Have been. A pipe 3 is formed in a cap 4 that covers the inlet 2. A pipe passage extends obliquely upward and then bends downward, and an outlet 3a is directed downward.

[0016] Thus, the overflowed cooling water falls straight and can be prevented from hitting other parts. Also, there is no need to lay out the drain tube connected to the pipe 3, the number of parts can be reduced, and the workability is improved.

As shown in FIGS. 3 to 6, a mounting bracket 9 is formed on the tank body 7 on the side opposite to the neck 8 protruding from the tank body 7, and is mounted on the side member 11 by screws 10. Reserve tank 1 of composition
It can be. The neck 8 has a size that can be inserted into a gap between the bumper 12 and the engine room 13. 14 is a radiator, 15 is a front member, 16
Indicates a headlamp.

As a result, as shown in FIGS. 5 and 6, the reserve tank 1 is positioned outside the engine room 13, the reserve tank 1 is fixed to the side member 11, and the inlet 2 protrudes inside the bumper 12. The overflowed cooling water can be discharged without hitting any parts. Also, by not installing the reserve tank 1 in the engine room 13, the engine room 13
Other components can be loaded into the vehicle, and various performances can be improved.

On the other hand, as shown in FIGS. 7 and 8, in the reserve tank 1 in which the inlet 2 faces obliquely upward, an annular projection formed on the cap 4 (means for fitting to the inlet).
At the tip of 4a, a cylindrical portion 17 to be inserted into the inlet 2 is formed.

In the case of this reserve tank 1, the inlet 2
Even if is facing obliquely upward, first, the cylindrical portion of the cap 4
17 is put on the inlet 2. In this state, the cap 4 does not fall even if the hand is released from the cap 4. Then, since the cap 4 is pressed and fitted, the mounting of the cap 4 becomes very easy.

[0021]

As described above, the present invention is constructed as described above, so that the neck is directed obliquely upward in the tank shape.
Other parts may be contaminated with cooling water because they are away from the top of the tank.
And not. Further, the reserve tank can be installed outside the engine room, and the empty space in the engine room can be used effectively.
