Example 11

As shown in fig. 1 to 9, the present embodiment provides a vehicle 10 including a vehicle body 300, a door window 200, and a door window sealing device 100, the door window 200 adopting a double sealing structure: the first seal ring 120 serves as a passive seal structure, and the second seal ring 130 serves as an active seal structure, and the double seal structure is fixed to the vehicle body 300. The first sealing ring 120 is provided with a hollow sealing strip and is arranged on a door frame of a window of the vehicle body 300, the sealing strip is made of high-temperature resistant material silicon rubber, the first sealing of the door and window 200 is formed, and dust outside the vehicle is isolated. The second sealing ring 130 is an inflatable sealing ring, is mounted on a threshold of the vehicle body 300, and is located at the inner ring of the first sealing ring 120 to avoid damage; the second sealing ring 130 is also made of high temperature resistant material silicone rubber to form a second seal of the door and window 200, so that toxic gas outside the vehicle can be isolated. The opening and closing of the active sealing structure can be automatically controlled by a travel switch of the vehicle door or manually controlled by an operator, and the air source 150 of the active sealing structure comes from the chassis air storage cylinder without additionally adding an air charging device.

Specifically, the door window 210 is opened and closed by a hinge 230 and a lock 240. A travel switch for sensing whether the door is closed in place is disposed on the vehicle body 300 at a position corresponding to the lock 240. Two sealing strip mounting grooves are arranged on the periphery of the door opening of the vehicle body 300, wherein the outer groove is used for mounting the first sealing ring 120, and the inner groove is used for mounting the second sealing ring. The first sealing ring 120 is made of high-temperature-resistant silicon rubber, and the lower part of the first sealing ring is of a rectangular structure, so that the first sealing ring is convenient to install; the upper part adopts a hollow structure. The second sealing ring 130 is integrally formed by high-temperature-resistant silicon rubber, and the lower part of the second sealing ring is of a rectangular structure, so that the second sealing ring is convenient to install. The first sealing ring 120 isolates external dust to form a first seal, and protects the second sealing ring 130. The second sealing ring 130 isolates outside toxic gas to form a second seal. To avoid damage from sharp objects, the second seal ring 130 is disposed in the second notch 114 in the non-inflated state; the second seal ring 130 is protected by the first seal ring 120 when in the inflated state. The stroke of the second sealing ring 130 is larger than the compression stroke of the first sealing ring 120, so that the influences of uneven gaps and untight sealing caused by door and window deformation can be eliminated.

The working process is as follows:

the door closing process:

as shown in fig. 3, when the door is in the open state, the first seal 120 is in a free state and the second seal 130 is in a non-inflated state. When the door is closed, the door panel compresses the first gasket 120 and the latch 240 locks the door. While the lock 240 actuates the travel switch of the door lock accessory. When the controller 146 is in the automatic state, the controller 146 receives an activation signal of the travel switch, first opens the solenoid valve as the on-off control valve 1442, and switches the two-position three-way directional valve as the directional valve 1444 of the corresponding vehicle door to the charge position. The air pressure of the chassis air cylinder is 0.8Mpa, the pressure is reduced to 0.3Mpa through the pressure reducing valve 4, the air flows to the flow divider 1448 through the electromagnetic valve, and the air is inflated to the corresponding second sealing ring 130 through the flow divider 1448 and the corresponding two-position three-way reversing valve, so that double-channel sealing is realized. When the controller 146 is in the manual state, the driver can operate the control switch corresponding to the second sealing ring 130 to the inflation position, and the controller 146 inflates the second sealing ring 130, so that the double-channel sealing is realized.

The door opening process:

as shown in fig. 5, when the door is in the closed state, the first seal ring 120 is in a compressed state and the second seal ring 130 is in an inflated sealing state. The lock 240 is opened, the door is slowly opened under the extrusion of the first sealing ring 120, and the travel switch is slowly reset at the same time. When the controller 146 is in the automatic state, the controller 146 receives a reset signal of the travel switch to change the two-position three-way directional valve of the corresponding vehicle door to the exhaust position. The second sealing ring 130 is internally provided with compressed air which is exhausted and decompressed through a corresponding two-position three-way reversing valve. When the controller 146 is in a manual state, the corresponding second sealing ring 130 can be manually operated by a driver to control the switch to the exhaust position, and the controller 146 controls the second sealing ring 130 to exhaust and release air.

To sum up, the utility model discloses beneficial effect does:

1. the door and window 200 adopts the first sealing ring 120 and the second sealing ring 130 which are respectively arranged on the vehicle body 300, so that the sealing problem after the welding deformation of the door and window 200 can be effectively solved. Under ordinary operating mode, can only select first sealing washer 120 to seal, perhaps under dense cigarette, poisonous and the operating mode of wading, select dual seal mode.
