The utility model solves the technical scheme that its technical matters adopts: a kind of automobile liquid storage tank lid and the tank mouth structure coordinating with it, comprise cover body, be arranged on the intrinsic ventilative sealing block of cover, the midway location of described ventilative sealing block is provided with ventilative chamber, below ventilative chamber, is provided with breather hole; On the upper surface that described ventilative sealing block coordinates with cover body, be provided with the first air channel, described the first air channel extends to the edge of ventilative sealing block to both sides from ventilative chamber, described ventilative sealing block leaves ventilative gap between the edge of the first ventilating groove and cover body; The bottom of described ventilative sealing block is also provided with and prevents that braking liquid is splashed into the washboard in breather hole.
For convenience of installing, on described ventilative sealing block, be provided with the first air channel described in two spacing card bases and be arranged on spacing card base; On described cover body, be provided with the air channel suitable with spacing card base, between spacing card base and air channel, leave ventilative gap.
For improving leak tightness, on described ventilative sealing block, be also provided with the seal ring suitable with fluid reservoir tank mouth inwall.
For convenience of installing, on described cover body, be also provided with one group of buckle, on suitable fluid reservoir tank mouth, be provided with draw-in groove with it, it is suitable for the fixing fixed end of buckle that described draw-in groove comprises that width is greater than the screw terminal of buckle and width and buckle.On described ventilative sealing block, be provided with one group card base is installed, on described cover body, be provided with the bayonet socket suitable with card base is installed.
For improving permeability to air, the bottom of described cover body is also provided with second air channel suitable with the first air channel.
The beneficial effects of the utility model: by being arranged on the ventilative sealing block on cover body, gas is from ventilative gap enters ventilative chamber, from the breather hole of ventilative sealing block bottom, enter in fluid reservoir, guarantee that gas can pass in and out fluid reservoir smoothly, simultaneously, described washboard can effectively prevent that the braking liquid in fluid reservoir is splashed into breather hole, thereby improves sealing property.Described seal ring can further improve the leak tightness of fluid reservoir.Described ventilative sealing block and cover body clamp, and easy to assembly, production efficiency is high.Described cover body and fluid reservoir tank mouth rotary clamping are fixed, and open closed is rapid, simple.
Below with reference to drawings and Examples, the utility model is described in detail.
