Description

Technical Field

[0001] The utility model belongs to the technical field of window sealing strips, and particularly relates to a window sealing strip. Background Art

[0002] A window sealing strip is an edge sealing strip applied and installed on automobile doors and windows. When the window is closed, the edge of the window and the door and window frame can be well sealed when combined, so as to prevent external air and rain from entering the vehicle.

[0003] In the prior art, the window sealing strip is made of elastic rubber material and generally includes a sealing strip body and a lip. The window sealing strip is installed on the door and window frame. When the window is closed and combined with the door and window frame, the sealing strip body will be extruded, so that the sealing strip body is closely attached to the window edge, and the window side wall abuts against the lip, thereby realizing the sealing of the window.

[0004] Although this method can achieve the sealing of the window, the structure of the window sealing strip is relatively simple. With the long-term and frequent opening and closing of the window, the lip of the sealing strip will be damaged by friction, and the sealing strip body is easily extruded frequently and becomes hard, resulting in poor elasticity, thus affecting the sealing performance. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a window sealing strip for solving the above technical problems in view of the above existing technical problems.

[0006] In view of this, the utility model provides a window sealing strip, including:

[0007] A sealing strip body with a cavity structure arranged inside;

[0008] Two lips respectively arranged on both sides of the sealing strip body along the first direction, and a conveying channel is arranged inside the lip;

[0009] Two expansion ridges respectively arranged on the two lips, and the inside of the expansion ridge is hollow;

[0010] Wherein, the cavity is connected to the inside of the two expansion ridges through the conveying channel. When the cavity is extruded, the gas in the cavity will flow into the expansion ridge through the conveying channel, causing the expansion ridge to expand and protrude along the first direction.

[0011] Further, the two lips are integrally connected to the sealing strip body.

[0012] Further, the expansion ridge is integrally connected to the lip.

[0013] Further, the sealing strip body and the two lips form a "U"-shaped window guide groove.

[0014] Further, it further includes:

[0015] A plurality of elastic bending pieces, which are arranged on the lip edge and located in the window guide groove.

[0016] Further, the elastic bending piece is integrally connected to the lip edge.

[0017] Further, it further includes:

[0018] An installation groove, which is arranged on the sealing strip body.

[0019] The beneficial effects of the present utility model are:

[0020] By arranging a cavity structure inside the sealing strip body, the extrusion impact received inside the sealing strip body is reduced, the elastic expansion and contraction of the sealing strip body is enhanced, the sealing performance of the window sealing strip is improved, and the service life is extended at the same time. By arranging an internally hollow expansion rib on the lip edge, the inside of the expansion rib is communicated with the cavity structure of the sealing strip body through a conveying channel. When the window squeezes the sealing strip body, the cavity structure is compressed, resulting in the expansion and protrusion of the expansion rib to abut against the side wall of the window, realizing the sealed connection between the window sealing strip and the side wall of the window, and further improving the sealing performance.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] Embodiment 1:

[0029] This embodiment provides a window sealing strip, including:

[0030] A sealing strip body 1, in which a cavity 11 structure is provided;

[0031] Two lips 2, which are respectively arranged on both sides of the sealing strip body 1 along the first direction X, and a conveying channel 12 is provided inside the lip 2;

[0032] Two expansion ribs 3, which are respectively arranged on the two lips 2, and the inside of the expansion rib 3 is hollow;

[0033] Wherein, the cavity 11 is communicated with the inside of the two expansion ribs 3 through the conveying channel 12. When the cavity 11 is squeezed, the gas in the cavity 11 will flow through the conveying channel 12 into the expansion rib 3, causing the expansion rib 3 to expand and protrude along the first direction X.

[0034] Furthermore, the sealing strip body 1 and the two lips 2 form a "U"-shaped window guide groove 4.

[0035] In this technical solution, the sealing strip body 1 and the expansion rib 3 are made of ethylene-propylene rubber material with good elasticity, and the lip 2 is made of rubber material that is not easily deformed. The sealing strip body 1 can be adhesively bonded in the window frame with glue. When a passenger or driver operates the air conditioner to move the window upwards, the top of the window enters the "U"-shaped window guide groove 4, and then the top of the window abuts against the sealing strip body 1 to squeeze the sealing strip body 1, so that the cavity 11 structure inside the sealing strip body 1 is compressed. After the cavity 11 structure is compressed, the air inside the cavity 11 will be conveyed through the conveying channel 12 of the lip 2 to the hollow inside of the expansion rib 3, causing the surface of the expansion rib 3 to protrude along the first direction X and abut against the side wall of the window, realizing a sealed connection.

[0036] In summary, by setting the cavity 11 structure inside the sealing strip body 1, the extrusion impact received inside the sealing strip body 1 is reduced, the elastic expansion and contraction of the sealing strip body 1 is enhanced, the sealing performance of the window sealing strip is improved, and the service life is extended at the same time. By providing the expansion rib 3 with a hollow interior on the lip 2, the interior of the expansion rib 3 is connected to the cavity 11 structure of the sealing strip body 1 through the delivery channel 12. When the window squeezes the sealing strip, the cavity 11 structure is compressed, causing the expansion rib 3 to expand and protrude to abut against the side wall of the window, realizing the sealed connection between the window sealing strip and the side wall of the window and further improving the sealing performance.

[0040] Furthermore, the expansion rib 3 is integrally connected to the lip 2.

[0041] In this technical solution, the sealing strip body 1, the lip 2 and the expansion rib 3 are of an integral structure. The cavity 11 structure of the sealing strip body 1, the delivery channel 12 of the lip 2 and the hollow interior of the expansion rib 3 are sequentially connected. When the window squeezes the cavity 11 structure of the sealing strip body 1, the gas in the cavity 11 structure is transported through the delivery channel 12 to the interior of the expansion rib 3, causing the expansion rib 3 to protrude and abut against the window, realizing further sealing between the window and the window frame.

[0046] Furthermore, the elastic bending piece 5 is integrally connected to the lip 2.

[0047] In this technical solution, the elastic bending piece 5 is made of a rubber material with good elasticity and is integrally connected to the lip 2. When the window enters the window guide groove 4, the window will first squeeze the elastic bending piece 5, and the elastic bending piece 5 will bend and abut against the side wall of the window, thereby realizing a further sealed connection between the window and the window frame, and further effectively improving the sealing performance after the automobile window is closed, with high practicability.
