Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-9, a waterproof and dustproof structure of an automobile oil filler box comprises a shell 1 fixed in an automobile body 21 and provided with a containing cavity 2, a port pipe 3 communicated with an oil tank, a hinge 4 rotatably connected with the shell 1, and an oil filling cover plate 5 arranged on the hinge 4, wherein a connecting port 6 is formed in the containing cavity 2 of the shell 1, the port pipe 3 is in butt joint communication with the connecting port 6, the containing cavity 2 is further provided with an outer opening 7, the hinge 4 can enter and exit the containing cavity 2 through the outer opening 7, a circle of first shell sealing element 11 is further arranged on the edge of the shell 1, and the first shell sealing element 11 is abutted against the automobile body 21 and forms sealing fit.

In the conventional mounting structure of the housing 1 and the vehicle body 21, an effective sealing structure is lacking, and therefore, a certain gap is present, so that it is easy to cause dirt (such as dust or water) to intrude from the gap between the housing 1 and the vehicle body 21. The utility model discloses in, through the setting of first casing sealing member 11 for casing 1 is inseparabler with being connected of automobile body 21, and can further promote the inside clean and tidy degree of automobile body 21.

In this embodiment, a hinge sealing member 8 is disposed on an outer edge of the hinge 4, a second casing sealing member 10 is disposed on an edge of the casing 1, and when the oil filling cover plate 5 is in a covering state, the hinge sealing member 8 abuts against the second casing sealing member 10 to form a sealing fit. By adopting the structure of the embodiment, when the oil filling cover plate 5 is in a closed state, a closed space is formed between the hinge 4 and the shell 1, so that foreign matters can be prevented from invading into the interior, and a good protection effect is achieved

In this embodiment, a circle of skirt 12 is disposed at the upper end of the housing 1, the second housing seal 10 is disposed on the upper end surface of the skirt 12, and the first housing seal 11 is disposed on the outer side wall of the skirt 12. Through the arrangement of the skirt 12, a better installation space is provided for the second shell sealing element 10 and the first shell sealing element 11, and the production and the assembly are more convenient.

In this embodiment, the lower end of the skirt 12 is provided with a plurality of first limiting clamping grooves 13 and first limiting protrusions 14, the first shell sealing element 11 is provided with a plurality of second limiting clamping grooves 15 and second limiting protrusions 16, the first limiting protrusions 14 are clamped into the second limiting clamping grooves 15, and the second limiting protrusions 16 are clamped into the first limiting clamping grooves 13; the skirt 12 is further provided with a positioning block 17 protruding outwards, the first casing sealing element 11 is provided with a positioning sleeve 18, and the positioning block 17 is inserted into the positioning sleeve 18. This scheme provides concrete assembly structure between shirt rim 12 and first casing sealing member 11, inserts locating piece 17 alignment position sleeve 18 earlier during the use, realizes the function of preassembly to play certain limiting displacement to first casing sealing member 11, convenient follow-up with whole first casing sealing member 11 and shirt rim 12 assembly together, this structural connection is enough firm, also more reliable during the use. Preferably, the first limit projection 14 and the second limit projection 16 are shaped in a special shape, so that the stability after connection can be further improved.

Preferably, a first fixing slot is formed in the upper end surface of the skirt 12, a first fixing portion is arranged at the lower end of the second casing sealing element 10, and the first fixing portion is inserted into the first fixing slot. The second housing seal 10 can be firmly connected to the skirt 12 by the cooperation of the first fixing portion and the first fixing groove. A second fixing clamping groove 19 is formed in the side wall of the hinge 4, a second fixing part 20 is arranged at the inner end of the hinge sealing element 8, and the second fixing part 20 is inserted into the second fixing clamping groove 19.
