In one embodiment, the water retaining groove 30 has a predetermined difference with the longest thickness of the valve frame 10 along the transverse length from the air inlet end to the air outlet end of the valve frame 10, and the predetermined difference is in the range of 1-3 mm.

In this embodiment, a specific range interval is given for a preset difference value of the length of the water retaining groove 30 being longer than the thickness of the valve frame 10, so that the water retaining groove 30 can play a role more fully and block more rainwater while increasing materials as little as possible, the range interval of the preset difference value is 1-3 mm, and in the range interval, the pressure release valve for the automobile can be reasonably designed and has certain aesthetic property, and the pressure release valve is easy to assemble with a vent at the tail of the automobile by an implementer in the field, so that unnecessary troubles caused by the pressure release valve are avoided.

In one embodiment, the longitudinal height of the exhaust hole site is 2-5 times the longitudinal height of the water retaining groove 30.

In this embodiment, in order to ensure the blocking effect of the water retaining groove 30, the longitudinal height of the water retaining groove 30 is further limited, because the sizes of the exhaust hole sites of different vehicle types can be changed adaptively, the specific ratio of the height of the water retaining groove 30 to the height of the exhaust hole site can ensure that the design is more reasonable, but the water retaining groove 30 which is too high cannot have the better effect of blocking rainwater but can influence the exhaust effect of the automobile pressure release valve, through repeated tests, the proportion interval formed by the longitudinal height of the exhaust hole site and the longitudinal height of the water retaining groove 30 is finally limited to be set between 1: 5 and 1: 2, and along with the increase of the vehicle speed or the increase of the vehicle type, the height of the water retaining groove 30 needs to be increased again, no more specific limitation is made in the text, and practitioners in the field can set the more appropriate longitudinal height of the water retaining groove 30 by themselves through different vehicle types, under the prerequisite of guaranteeing not to influence the relief valve exhaust effect, make the automobile of this application when using the relief valve more reasonable can.

As shown in fig. 1, in one embodiment, the valve frame 10 includes a peripheral frame 11, two or more cross beams 12 and a supporting longitudinal beam 13, wherein the peripheral frame 11 is horizontally provided with the two or more cross beams 12, and two ends of the supporting longitudinal beam 13 are disposed between the peripheral frame 11 and the cross beams 12 or between two adjacent cross beams 12.

In this embodiment, it should be pointed out specifically that, the setting of supporting longitudinal beam 13, the pressure that the release rainwater that can be better is piled up in manger plate groove 30, the rainwater can not only follow the both sides of peripheral frame 11 or blade 20 following current and down, and partial rainwater can also follow a plurality of supporting longitudinal beams 13 following currents that add and fall into manger plate groove 30, further improves drainage efficiency, and the supporting longitudinal beam 13 that reasonable quantity set up can not influence the exhaust effect of the pressure release valve for the car of this application embodiment.

In one embodiment, the support stringers are angled such that the bottom end of each support stringer is angled toward the exhaust end of the valve frame 10.

In the embodiment, the support longitudinal beams are obliquely arranged, specifically, the support longitudinal beams are gradually inclined towards the outer side of the automobile from the top to the bottom, and the obliquely arranged support longitudinal beams can effectively prevent a small part of rainwater from flowing into the automobile from the top of the water retaining groove 30.

In one embodiment, the exhaust holes are divided into a plurality of parts by more than two cross beams 12 and a plurality of support longitudinal beams, and a single blade 20 covers a row of exhaust holes in the transverse direction.

In this embodiment, a single blade 20 covers a row of transverse exhaust holes, and compared with the case that a single large blade 20 is divided into a plurality of small blades 20, the single large blade 20 directly covers a row of transverse exhaust holes, so that the machining processes are reasonably reduced, unnecessary troubles for the implementation personnel in the field are avoided, and the cleaning, maintenance and replacement after long-term use are facilitated.

In this embodiment, the rotatable connection of the vanes 20 to the valve frame 10 is typically detachable to facilitate replacement by those skilled in the art, but care should not be taken to detach them easily to ensure that the vanes 20 do not fall off due to jolting during vehicle operation or are blown off by pressure during venting.
