The fuel filling pipe is arranged at the wheel cover and is provided with a fender, the carbon tank is connected with the filter through a section of pipeline, and the filter is arranged in the wheel cover. The filter is connected with a carbon tank through a section of pipeline, but the filter is placed at a higher position of the chassis. Since the ventilation line is thick and installation convenience is a problem, the connection pipe needs to be disposed in many ways, which results in high cost of the connection pipe.

Disclosure of Invention

The invention aims to solve the problem of high connection cost and inconvenience in connection of an activated carbon tank and a filter of an existing automobile oil supply system.

In order to solve the problems, the technical scheme of the invention is as follows: this car activated carbon jar is including the charcoal jar that has shell, big mouth of a river joint, and the filter, the filter is including inlaying the last casing and the lower casing of dress each other, it is equipped with the filter joint to go up the casing, still be equipped with on the lower casing of filter be used for with filter support and mounting hole on other parts of car are installed to the filter, the big mouth of a river joint department of charcoal jar through a quick-operation joint with filter articulate, quick-operation joint is equipped with and is used for the assembly the screens recess that the big mouth of a river joint of charcoal jar, filter support stretches out there is a hole ear, be equipped with on the shell of charcoal jar with the buckle of the hole ear looks chucking of filter, the filter joint passes through quick-operation joint with the charcoal jar is connected the back, and is rotatory filter support extremely the filter hole ear with the buckle looks chucking of charcoal jar shell.

In the above technical solution, a more specific solution may be: the buckle of the carbon tank is arranged on the buckle bracket of the carbon tank shell.

Further: the hole ear of the filter is a mounting hole of the filter bracket for mounting the filter on other parts of the automobile.

Further: and a sealing ring is arranged in the clamping groove of the quick connector.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:

the automobile activated carbon canister adopts the quick connector to match and integrate the large air port connector of the carbon canister and the connector of the filter, and meanwhile, a buckle bracket for mounting the filter is additionally arranged on the shell of the carbon canister, so that the filter is directly assembled on the carbon canister, connecting pipelines are reduced, the structure is compact, the arrangement of an oil tank is convenient, and the filter can be placed in an oil tank-carbon canister module, so that the whole automobile production line does not need to be adjusted due to the assembly of the filter, the modularization degree is improved, the pipeline between the carbon canister and the filter and two connectors are eliminated, and the system cost is reduced; the filter is directly assembled on the carbon tank without a connecting pipeline, so that the pipeline resistance is reduced, and the risk of gun jump in advance during ORVR refueling is reduced; utilize the bolt mounting hole on the former filter support of filter as the hole ear, install on the charcoal jar shell, utilize the rotatable characteristic between the upper and lower casing of filter, rotatory filter during the assembly, rotatory filter installing support drives the casing rotation down promptly, and the buckle of charcoal jar buckle support is gone into to the mounting hole card on the installing support, restriction filter axial rotary motion.

Detailed Description

The embodiments of the invention will be described in further detail with reference to the accompanying drawings:

the automobile activated carbon canister shown in fig. 1, 2, 3 and 4 comprises a carbon canister with a shell 14, an upper cover 9, a large air port joint 10 and a filter. The filter comprises an upper shell 5 and a lower shell 6 which are embedded mutually, the upper shell 5 is provided with a filter joint 4, and the lower shell 6 of the filter is also provided with a filter bracket 7 and a mounting hole 8 which are used for mounting the filter on other parts of the automobile.

The upper cover 9 of the carbon canister is arranged at one end of the shell 14, the atmosphere port joint 10 is arranged on the upper cover 9, and the atmosphere port 10 is provided with a boss 11 for preventing the filter from loosening.
