The invention relates to the technical field of car lamps, and discloses a valve body of a car lamp rear cover, which comprises a silica gel block, a cross valve is arranged on the silica gel block, a matching piece is adhered to the inner wall of the silica gel block, an inner stopper is arranged on the other side of the matching piece, and the inner stopper comprises a main plate, a spiral bulge, a bulge roller and a square column, the center of the main plate is in a barrel shape, a circular plate is fixed to the outer side of the barrel shape, a through hole is formed in the center of the main plate, and protruding sails arranged in a circumferential array shape are arranged at the upper end of the circular plate of the main plate. The cross valve is arranged on the silica gel block, and when air pressure difference exists between the air pressure in the silica gel block and the external air pressure, the cross valve is opened through the air pressure difference, so that the external air communicates with the air in the silica gel block, the air pressure in the silica gel block is adjusted, and when air pressure difference exists between the air pressure in the silica gel block and the external air pressure, the air pressure in the silica gel block can be automatically adjusted.

    本发明涉及车灯技术领域,且公开了一种车灯后盖的瓣膜阀体,包括硅胶块,所述硅胶块上开设有十字阀,所述硅胶块的内壁上粘接有配合件,所述配合件的另一侧设有内挡件,所述内挡件包括主板,螺旋凸起,凸起辊,方柱,所述主板中心处为桶状,且在桶状外侧固定有圆板,所述主板中心处开设有通孔,所述主板的圆板上端设有呈圆周阵列状排列的凸起帆。本发明通过在硅胶块上设有十字阀,当硅胶块内部的气压与外部气压存在气压差的时候,通过气压差使十字阀打开,使外部的空气与硅胶块内部的空气进行相连通,用来调节硅胶块内部的气压,使硅胶块内部气压与外部气压存在气压差的时候,即可自动调节硅胶块内部的气压。
