Sealing device disposed between a vehicle door and a vehicle body
Disclosed herein is a sealing device disposed between a vehicle door and a vehicle body and a vehicle door sealing rubber strip thereof. The sealing rubber strip is sleeved on a door pipe of the vehicle door. The vehicle door sealing rubber strip is an annular rubber body constituted by a drain segment and a non-drain segment. The annular rubber body includes a hollow rubber ring made of foaming rubber and a groove-shaped rubber ring made of compacted solid rubber and provided with a pipe body mounting groove at the inner side of the groove-shaped rubber ring. An air hole is provided in the hollow rubber ring, and a small water flowing trench is provided at the bottom surface of the pipe body mounting groove of the groove-shaped rubber ring. A fixing groove with a broad bottom and a narrow opening is provided on one external side of the groove-shaped rubber ring. A water flowing channel disposed transversely and a draining through hole communicated with the water flowing trench are provided on the other side surface of the groove-shaped rubber ring at the drain segment. Compared with the prior art, such device can solve the problem of unreliable sealing between a vehicle body doorframe and a vehicle door which are made of circular pipes and the difficulty of draining water accumulated inside the vehicle door.
1. A sealing device disposed between a vehicle door and a vehicle body, comprising a doorframe formed of circular pipes and provided on the vehicle body, a door pipe at an outer edge of the vehicle door formed of circular pipes, and a vehicle door sealing rubber strip, wherein the vehicle door sealing rubber strip is an annular rubber body constituted by a drain segment and a non-drain segment, the annular rubber body comprises a hollow rubber ring made of foaming rubber and a groove-shaped rubber ring made of compacted solid rubber and provided with a pipe body mounting groove at the inner side of the groove-shaped rubber ring, the pipe body mounting groove is sleeved on the door pipe, the drain segment is provided at a lowest portion of the door pipe, and a small water flowing trench is provided between the door pipe and a bottom surface of the pipe body mounting groove outside the door pipe; an air hole is provided in the hollow rubber ring, a fixing groove with a broad bottom and a narrow opening is provided on one external side of the groove-shaped rubber ring; at the drain segment and on the other side opposite to the fixing groove, a height of a wall of the groove-shaped rubber ring at the drain segment is lower than that at the non-drain segment on the same side, an external surface of the wall of the groove-shaped rubber ring at the drain segment is recessed inwardly relative to an external surface of a wall at the non-drain segment on the same side, so as to form a water flowing channel; and a draining through hole communicated with the small water flowing trench is provided in the wall of the drain segment at the other side.
2. A vehicle door sealing rubber strip, being an annular rubber body which is constituted by an drain segment and a non-drain segment, wherein the annular rubber body comprises a hollow rubber ring made of foaming rubber and a groove-shaped rubber ring made of compacted solid rubber and provided with a pipe body mounting groove at the inner side of the groove-shaped rubber ring, an air hole is provided in the hollow rubber ring, a small water flowing trench is provided at a bottom surface of the pipe body mounting groove of the groove-shaped rubber ring, a fixing groove with a broad bottom and a narrow opening is provided on one external side of the groove-shaped rubber ring; at the drain segment and on the other side opposite to the fixing groove, a height of a wall of the groove-shaped rubber ring at the drain segment is lower than that at the non-drain segment on the same side, an external surface of the wall of the groove-shaped rubber ring at the drain segment is recessed inwardly relative to an external surface of a wall at the non-drain segment on the same side, so as to form a water flowing channel; and a draining through hole communicated with the small water flowing trench is provided in the wall of the drain segment at the other side.
