Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a canister mounting structure which improves the mounting workability of a canister used in a vehicle such as an automobile and can accommodate a plurality of vehicle types.

[0002]

2. Description of the Related Art In vehicles such as automobiles, gasoline, which is a fuel, evaporates from a fuel tank or a carburetor. Therefore, a canister is used so that the gasoline does not diffuse into the atmosphere. This canister is usually provided inside the engine room. FIG. 16 shows this. 1 is a car body line, 2 is a dash panel, and the front part of the dash panel 2 is an engine room 3. Inside the engine room 3, a transmission 4, a radiator 5, a brake booster 6, a canister 7, etc., which are coupled to the engine, are housed. Reference numeral 8 is a bracket for attaching the canister 7 to the dash panel 2, 9 is a cylinder head of an engine (not shown), and 10 is a distributor.

In the illustrated example, the canister 7 is located above the transmission 4 and in front of the brake booster 6. By the way, since the canister should be as large as possible, the shape, size, and mounting structure should be designed according to the mounting location for each vehicle type. However, if possible, it is desirable to have versatility that can be adapted to any of a plurality of vehicle types from the viewpoint of mounting workability and cost reduction.

Therefore, the mounting structure is devised so that one canister can be used for a plurality of vehicle types. Figure 14
Shown in FIG. 3 is a canister 7 manufactured for this purpose. This canister 7 has wedge-shaped projections 12 provided on the four outer peripheral surfaces of a case 11 containing activated carbon therein. The protrusions 12 engage with four engaging portions 14 provided on the side of the dash panel 2 (see FIG. 2) which is a vehicle body side member. Protrusion 12
Has a wedge shape, the four engaging portions 14 are arranged so as to match this. Reference numerals 15 to 17 in the figure denote connecting pipes.

[0005]

In order to mount the canister 7 on the dash panel 2 which is the vehicle body side in the canister mounting structure having such a structure, the canister 7 having a rectangular shape when viewed from above is oriented in a desired direction. Any one of the protrusions 12 provided individually is engaged with the engaging portion 14 of the bracket 13. FIG. 15 shows the state of attachment in this way. As shown in FIG. 15, since the canister 7 is provided with one protrusion 12 on each side, three of them are not used.

Therefore, the unused protrusion 12 is provided in the vicinity of another member such as the cable 18 in FIG.
You will not be able to get in contact with or secure the required distance. Further, since the four protrusions 12 are provided, there is a possibility that incorrect assembly may occur.

When the projection 12 contacts another member or cannot secure the required distance as described above, it is necessary to deal with this by changing the arrangement of the other member. In addition, when it was improperly assembled, it took time to correct it. The present invention has been made in view of this point, without contacting other members or shortening the distance as described above, and also does not cause erroneous assembly,
It is intended to provide a mounting structure for a canister.

As a prior art, there is a canister which can be mounted from above and laterally in Japanese Utility Model Laid-Open No. 3-41154. However, in this publication,
This is merely for the convenience of mounting, and does not solve the above-mentioned problems to be solved by the present invention.

[0009]

As a means for solving the above problems, the present invention provides a bracket on a vehicle body side member of a vehicle, and a projection provided on a case of a main body is engaged with the bracket to form a canister. In the mounting structure of the supported canister, bracket engaging portions are formed at upper and lower edges of the canister, and upper and lower end portions of a canister bracket separately provided in the bracket engaging portion are engaged with each other, and a rear portion of the canister bracket is attached. The configuration is such that an engaging portion that engages with a bracket provided on the vehicle body side member is formed.

Further, the canister bracket has an upper bracket partly formed with a hook portion for engaging a bracket engaging portion on an upper portion of the canister, and a lower end portion provided with a hook portion for engaging with a bracket engaging portion on a lower portion of the canister. It is formed by a lower bracket, and the upper bracket and the lower bracket are connected by bolts.

Further, the upper bracket and the lower bracket are formed by pressing a metal plate, and a wedge-shaped engaging portion is formed on the back portion of the lower bracket by resin insert molding.

[0012]

With this structure, the canister bracket is attached to the canister, and in that state, the engaging portion provided on the back of the canister bracket is engaged with the bracket provided on the vehicle body side member from above. The canister can be attached to the vehicle body side member.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Flange-shaped bracket engaging portions 19 and 20 are formed on the upper and lower edges of the canister 7, and the upper and lower end portions of a canister bracket 21 separately provided are engaged with the bracket engaging portions 19 and 20. There is. A wedge-shaped engaging portion 22 that engages with a bracket 13 provided on a vehicle body side member such as a dash panel is formed on the back of the canister bracket 21.

The canister bracket 21 is composed of an upper bracket 23 and a lower bracket 24 connected to the upper bracket 23. The upper bracket 23 is partially formed with a hook portion 25 that engages with the bracket engaging portion 19 on the upper portion of the case 11 of the canister 7. On the other hand, the lower bracket 24 is formed at its lower end with a hook portion 26 that engages with the bracket engaging portion 20 in the lower portion of the case 11 of the canister 7. The above-mentioned engaging portion 22 is provided on the lower bracket 24 by insert molding.

The upper bracket 23 and the lower bracket 24 are formed by pressing a metal plate, and the wedge-shaped engaging portion 22 is formed on the back portion of the lower bracket 24 by resin insert molding. . As shown in FIG. 3, even in the case of the present invention, the bracket 13 provided on the vehicle body side member is the same as the conventional one, and therefore the shape of the engaging portion 22 is the same as that of the engaging portion 12 in FIG. It will be shaped. Note that this component will be described later.

The hook portion 26 of the lower bracket 24 is engaged with the lower bracket engaging portion 20 of the case 11 of the canister 7, and the upper bracket engaging portion of the case 11 of the canister 7 is engaged.
When the hook portion 25 of the upper bracket 23 is engaged with 19 and the upper bracket 23 and the lower bracket 24 are joined by the bolt 27, the state shown in FIG. 2 is obtained. In this state, the case 11 and the engaging portion 22 of the lower bracket 24 are integrated, so the canister 7 is attached to the bracket 13 attached to the vehicle body side member by the same procedure as described with reference to FIG. be able to.

FIG. 4 is a plan view showing the state of attachment in this way. In this case, since the engaging portion 22 does not protrude to an unnecessary place, a distance a can be formed between the engaging portion 22 and the cable 18, which is another member provided in the vicinity of the case 11, so that there is no interference.

5 to 7 show the shape of the upper bracket 23 in plan, front and side views, and FIGS. 8 to 13 show the shape of the lower bracket 24 in front, bottom, central cross section, oblique upper surface, rear and FIG. It is shown by the AA cross section. As mentioned above, these are formed by pressing a metal plate,
Although the lower bracket 24 is insert-molded with the resin-made engaging portion 22, the whole may be obtained by resin-molding.

Since the canister bracket 21 can be mounted on any side of the case 11 when the upper bracket 23 and the lower bracket 24 are not joined, the mounting location may be selected appropriately in consideration of the layout of the engine room. .

[0020]

Since the present invention has the canister mounting structure configured as described above, the canister case has the engaging portion only at the mounting portion and not at other portions, so that the canister or the like is not attached. A sufficient clearance with other parts can be secured. The canister bracket can be disassembled and its total length can be adjusted, so it can be attached to any side of the canister, giving greater freedom in layout in the engine room. And it is possible to support multiple models. Since the engaging portion is formed on only one of the four sides of the canister, workability of mounting is improved and erroneous assembly does not occur.
