Description

Technical Field

[0001] The utility model relates to the technical field of plug sliding doors, in particular to a plug sliding door sealing device. Background Art

[0002] A plug-and-slide door refers to a vehicle door system in which the door body has two actions: plugging and pulling. When closing, the door body is inserted into the door opening from the inside or outside of the vehicle body to achieve the door closing and sealing functions. When the vehicle body is opening, the door body extends to the inside or outside of the vehicle body and then moves a certain distance out of the door opening to achieve the opening function.

[0003] A circle of rubber strip is usually set on the outside of the existing Sierra door to ensure a certain degree of sealing when the Sierra door is closed. However, due to the different altitudes and air pressure environments in different regions, the conventional sealing structure will experience certain sealing failures under different air pressure environments. At the same time, the sealing structure of the Sierra door lacks an anti-pinch mechanism that can improve the safety of closing the door.

[0004] The existing closed sealing structure of the plug sliding door has the following drawbacks: the sealing structure of the existing plug sliding door of the car has the problem of having both the sealing effect and the anti-pinch effect. To this end, we propose a plug sliding door sealing device. Utility Model Content

[0005] The main purpose of the utility model is to provide a plug door sealing device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A plug door sealing device includes a plug door and an anti-pinch assembly, and also includes a U-shaped rubber sealing ring, an air pipe and an air valve. The anti-pinch assembly is arranged on one side of the plug door, the U-shaped rubber sealing ring is coated on the periphery of the plug door, and the anti-pinch assembly is located inside the U-shaped rubber sealing ring. The two sides of the U-shaped rubber sealing ring are respectively glued and fixed to the plug door.

[0008] Furthermore, the anti-pinch assembly includes a pressing plate, a guide column, a spring and a pressure sensor, and the pressing plate is arranged equidistantly from the top to the bottom of the closed plug door.

[0009] Furthermore, the guide columns are provided in multiple groups, and the guide columns are fixedly connected at equal distances from the top to the bottom along one side of the pressing plate. The guide columns are inserted into the plug door, and the springs are all sleeved on the guide columns, and the two ends of the springs are respectively welded to the pressing plate and the plug door.

[0010] Furthermore, the pressure sensor is installed and fixed at equal distances from the top to the bottom of the closed plug door.

[0011] Furthermore, the top of the U-shaped rubber sealing ring is connected to an air pipe, and the air inlet end of the air pipe is connected to an air valve.

[0012] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of an anti-pinch component, a U-shaped rubber sealing ring, an air pipe and an air valve, a sealing mechanism with an anti-pinch component is provided for the plug door, and the U-shaped rubber sealing ring is used to increase the sealing of the outer periphery of the plug door, so that the plug door maintains good sealing after closing, and at the same time, the inner cavity of the U-shaped rubber sealing ring can be inflated through the air pipe to expand the U-shaped rubber sealing ring, thereby further increasing the sealing of the plug door after closing. Through the setting of the pressing plate of the anti-pinch component, when the pressing plate is pressed during the closing of the plug door, the pressing plate will press the pressure sensor, so that the pressure sensor receives the signal and transmits it to the central control of the car, and the plug door is braked to close, thereby realizing anti-pinch processing, and solving the problem that the sealing structure of the plug door of the existing car has both sealing effect and anti-pinch effect.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-5As shown, a plug door sealing device includes a plug door 1 and an anti-pinch assembly 2, and also includes a U-shaped rubber sealing ring 3, an air pipe 4 and an air valve 5. The anti-pinch assembly 2 is arranged on one side of the plug door 1, the U-shaped rubber sealing ring 3 is covered on the periphery of the plug door 1, and the anti-pinch assembly 2 is located in the U-shaped rubber sealing ring 3, and the two sides of the U-shaped rubber sealing ring 3 are respectively glued and fixed to the plug door 1.

[0021] The anti-pinch assembly 2 includes a pressing plate 201, a guide column 202, a spring 203 and a pressure sensor 204, and the pressing plate 201 is arranged equidistantly from the top to the bottom of the closed plug door 1.

[0022] Among them, the guide column 202 is provided with multiple groups, and the guide column 202 is fixedly connected at equal distances from the top to the bottom along one side of the pressing plate 201. The guide column 202 is inserted into the plug door 1, and the springs 203 are all sleeved on the guide column 202. The two ends of the spring 203 are respectively welded to the pressing plate 201 and the plug door 1.

[0023] The pressure sensor 204 is installed and fixed at equal distances from the top to the bottom of the closed plug door 1.

[0024] The top of the U-shaped rubber sealing ring 3 is connected to an air pipe 4 , and the air inlet end of the air pipe 4 is connected to an air valve 5 .

[0025] It should be noted that the utility model is a plug door sealing device. When working, the personnel connect the air supply component on the vehicle with the air inlet end of the air valve 5, and connect the signal output end of the pressure sensor 204 with the central control of the car. Under the use state of the conventional air pressure environment, based on the elastic effect of the U-shaped rubber sealing ring 3 itself, the outer periphery of the plug door 1 can have a certain sealing property after the plug door 1 is closed. When the car is driving at different altitudes, the expansion state can be adjusted by inflating and deflating the U-shaped rubber sealing ring 3 to make the U-shaped rubber sealing ring 3 have a certain sealing property. The ring 3 provides a better sealing effect for the periphery of the Sierra door 1. While the U-shaped rubber sealing ring 3 maintains sealing, when foreign objects are trapped in the closed part of the Sierra door 1 during the closing period, the pressing piece 201 inside the U-shaped rubber sealing ring 3 will be squeezed, and the pressing piece 201 will transmit the pressure to the pressure sensor 204. After receiving the pressure signal, the pressure sensor 204 will transmit the signal to the car central control, and the Sierra door will be braked through the car central control to prevent the Sierra door 1 from further clamping foreign objects, thereby realizing anti-pinch treatment and greatly increasing the safety of passengers entering the Sierra door 1.
