The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The use of the terms "and / or" includes a combination of one or more of the associated listed items.

[0028] Please refer to Figures 1-2 The application provides a sealing strip 10, which comprises a main body 100, a groove 110 is arranged on the inner side of the main body 100 for a sheet metal part 20 of a vehicle to extend into, a skeleton 200 is arranged in the main body 100 and surrounds the groove, and a cavity 120 is further arranged in the main body 100 and is located on the side of the skeleton 200 away from the groove 110. The sealing strip 10 can be installed on the edge of a side door, a side door frame, a trunk door or a back door frame of a vehicle, and the following is described by taking the installation on the back door frame as an example.

[0029] It can be understood that the sealing strip 10 further comprises a clamping part 300 and a foaming part 400, the clamping part 300 is located in the groove 110, the main body 100 comprises a bottom wall 150 and a side wall 160, and the foaming part 400 is connected to the side of the bottom wall 150 away from the groove 110 and is located outside the main body 100. When the sealing strip 10 in the embodiment is installed on the sheet metal part 20 of the back door frame of the vehicle, the clamping part 300 is clamped on the edge of the sheet metal part 20, and the side of the main body 100 with the cavity 120 faces the outside of the vehicle. Since the cavity 120 can shield the traces of the skeleton 200, when the sealing strip 10 is exposed, the traces of the skeleton 200 will not be exposed, so that the appearance of the sealing strip 10 is more beautiful, and the whole vehicle is more beautiful. When the vehicle door is closed, the foaming part 400 is extruded by the edge of the vehicle door and the edge of the sheet metal part 20 at the back door frame and is clamped between the vehicle door and the sheet metal part 20, so that the foaming part 400 can seal the vehicle door and the back door frame.

[0030] Illustratively, the main body 100 and the clamping part 300 of the sealing strip 10 can use EPDM (ethylene propylene rubber) dense rubber, because the EPDM dense rubber has compact structure, excellent ozone resistance, heat resistance, aging resistance and other properties, so that the structure of the main body 100 and the clamping part 300 is stable and not easy to deform; the foaming part 400 can use EPDM sponge rubber, because the EPDM sponge rubber adds a foaming agent and has loose structure, so that the foaming part 400 is soft and easy to deform, thereby having good sealing effect.

[0031] Further, the material for manufacturing the sealing strip 10 can be extruded by using an extrusion die, so that the sealing strip 10 is integrally formed. The sealing strip 10 with the cavities 120 can be obtained by reserving the positions of the cavities 120 on the extrusion die. In other embodiments, the sealing strip 10 can be manufactured by using other methods, and the manufacturing method of the sealing strip 10 is not limited in the present application.

[0032] In one embodiment, the main body 100 includes a bottom wall 150 and a side wall 160 connected to one side of the bottom wall 150, and the bottom wall 150 and the side wall 160 surround the groove 110. The cavities 120 are arranged in the side wall 160, and one end of the flange structure 140 is connected to the connection between the bottom wall 150 and the side wall 160, and the other end extends towards the side wall 160. As described above, the bottom wall 150 of the sealing strip 10 is further connected to the foaming part 400. The one end of the flange structure 140 is connected to the connection between the bottom wall 150 and the side wall 160, which does not affect the arrangement of the foaming part 400, and does not excessively expose the foaming part 400, thereby not affecting the aesthetics of the vehicle interior.

[0033] In one embodiment, the number of cavities 120 is greater than or equal to two. In this way, the cavities 120 are less likely to deform. When the number of cavities 120 is only one, the shape of the cavity 120 is elongated, and the cavity 120 is prone to collapse, thereby affecting the aesthetics of the exposed part of the sealing strip 10, and further affecting the aesthetics of the vehicle as a whole. As shown in FIG. 4, the number of cavities 120 in this embodiment is two, but in other embodiments, the number of cavities 120 is greater than two. The number of cavities 120 is not limited in the present application. Figure 1

[0034] In one embodiment, the plurality of cavities 120 are arranged in a row, and the plurality of cavities 120 are arranged at intervals in the direction in which the groove wall 111 of the groove 110 extends. It can be understood that increasing the number of cavities 120 increases the volume of the sealing strip 10 and increases the design difficulty of the extrusion die. By increasing only one row of cavities 120, the volume of the sealing strip 10 can be prevented from being too large, and the extrusion die can be simplified, which only needs to be able to block the marks on the skeleton 200 towards the outside of the vehicle. It should be further noted that when the sealing strip 10 in the present embodiment is installed on the back door frame, the side with the cavities 120 should be installed towards the outside of the vehicle, so that the marks on the skeleton 200 are not exposed, thereby improving the aesthetics of the vehicle interior.

[0035] ​Further, the height of the cavity 120 is H1, and H1 ranges from 1 mm to 2 mm. If the height of the cavity 120 is too small, the cavity 120 cannot shield the skeleton 200 due to being too thin. If the height of the cavity 120 is too large, the volume of the sealing strip 10 is increased, which affects the installation of the sealing strip 10 on the panel 20 of the vehicle. The height of the cavity 120 in the embodiment is appropriate, so that the cavity can shield the traces on the steel skeleton and maintain stability. Illustratively, H1 can also be 1.25 mm, 1.5 mm, 1.75 mm, or any other value within the range of 1 mm≤H1≤2 mm.

[0036] In an embodiment, a partition 130 is arranged between adjacent cavities 120, and the height of the partition 130 is H2, and H2 ranges from 2 mm to 3.5 mm. It can be understood that one of the functions of the partition 130 is to prevent the cavity 120 from collapsing and deforming. The height of the partition 130 is higher than the height of the cavity 120, so that the cavity 120 can be better prevented from collapsing and deforming. Illustratively, H2 can also be 2.5 mm, 3 mm, or any other value within the range of 2 mm≤H2≤3.5 mm.

[0037] Further, the thickness of the partition 130 is D1, and D1 ranges from 1 mm to 2 mm. If the thickness of the partition 130 is less than 1 mm, the current process level is difficult to achieve. If the thickness of the partition 130 is greater than 2 mm, not only the space of the cavity 120 is excessively occupied, but also the weight and cost of the sealing strip 10 are increased. Therefore, the thickness of the partition 130 in the embodiment is appropriate. Illustratively, D1 can also be 1.25 mm, 1.5 mm, 1.75 mm, or any other value within the range of 1 mm≤D1≤2 mm.

[0038] In an embodiment, the outer side of the main body 100 is provided with a flange structure 140, and the flange structure 140 is located on the same side of the skeleton 200 as the cavity 120, that is, the flange structure 140 in the embodiment also faces the outer side of the vehicle. According to the prior art, the sealing strip 10 is installed between the back door frame and the door of the vehicle, and the rear bumper 30 is also arranged inside the back door frame of the vehicle. There is a gap of 2 mm-3 mm at the matching position of the sealing strip 10 and the rear bumper 30, which affects the appearance. The flange structure 140 is arranged to shield the gap, so that the interior of the vehicle is more beautiful.

[0039] In one embodiment, the flange structure 140 has an angle a with the side wall 160 of the body portion 100, and the angle a is in the range of 40 degrees to 60 degrees. It is understood that the main function of the flange structure 140 is to shield the gap at the joint between the weather strip 10 and the rear bumper 30. If the angle between the flange structure 140 and the body portion 100 is too small or too large, the flange structure 140 cannot shield the gap at the joint between the weather strip 10 and the rear bumper 30. Therefore, in the present embodiment, the angle a is in the range of 40 degrees to 60 degrees, which can ensure that the flange structure 140 can shield the gap at the joint between the weather strip 10 and the rear bumper 30. For example, the angle a can also be 45 degrees, 50 degrees, 55 degrees, or any other value in the range of 40 degrees to 60 degrees.

[0040] In one embodiment, the flange structure 140 has a bending portion 141 at the end away from the body portion 100, and the angle between the bending portion 141 and the body portion 100 is in the range of 30 degrees to 50 degrees, and the degree of the angle is smaller than the degree of the angle a. Therefore, the flange structure 140 can better shield the gap at the joint between the weather strip 10 and the rear bumper 30. For example, the angle can also be 35 degrees, 40 degrees, 45 degrees, or any range formed by any two of these values, as long as the degree of the angle is smaller than the degree of the angle a.

[0041] In one application, the vehicle using the weather strip described above has a rear bumper 30. The end of the bending portion 141 of the flange structure 140 away from the body portion 100 abuts against the rear bumper 30, and the interference amount between the end and the rear bumper 30 is L2, and L2 is in the range of 0.5 mm to 2 mm. It is noted that the interference amount refers to the length of the overlapping part between the end of the weather strip 10 away from the body portion 100 and the rear bumper 30, or the compression amount of the end of the weather strip 10 due to abutting against the rear bumper 30. In the present embodiment, L2 is in the range of 0.5 mm to 2 mm, which can ensure that the flange structure 140 can shield the gap at the joint between the weather strip 10 and the rear bumper 30. For example, L2 can also be 0.75 mm, 1 mm, 1.5 mm, or any range formed by any two of these values.

[0042] In an embodiment, the length of the flange structure 140 is L1, and L1 is in a range of 8mm to 11mm. If the length of the flange structure 140 is too short, the flange structure 140 cannot shield the gap at the joint position of the sealing strip 10 and the rear bumper 30, and if the length of the flange structure 140 is too long, the flange structure 140 is redundant, and even affects the closing of the door and the back door frame. Therefore, the length of the flange structure 140 in the embodiment can just shield the gap at the joint position of the sealing strip 10 and the rear bumper 30. Illustratively, L1 can also be 9mm, 9.5mm, 10mm, 10.5mm, 11mm, or any other value in the range of 8mm≤L1≤11mm.

[0043] In an embodiment, the thickness of the flange structure 140 is D2, and D2 is in a range of 1.5mm to 2mm. Therefore, the material can be saved, and the production cost is reduced. Illustratively, D2 can also be 1.6mm, 1.7mm, 1.8mm, 1.9mm, or any other value in the range of 1.5mm≤D2≤2mm.

[0044] In an embodiment, the sealing strip 10 further comprises a lip 500 in a C shape, which is connected to the outer side of the main body 100 away from the flange structure 140, and is used to cover the interior trim panel. The middle position of the lip 500 is further provided with a pulling part 510. Before installing the sealing strip 10 in the embodiment, a rope can be embedded in the pulling part 510. In use, the sealing strip 10 is manually installed on the edge of the sheet metal part 20, and the lip 500 needs to be pressed against the interior trim panel of the vehicle. However, since it is manually installed, and the sealing strip 10 is long, the lip 500 may be pressed under the interior trim panel during the installation process. At this time, the rope embedded in the pulling part 510 is pulled, the pulling part 510 is pulled out, and the lip 500 is also pulled out. Therefore, the lip 500 can cover the interior trim panel. In other embodiments, other ways can be used to pull out the pulling part 510 or the lip 500, which are not limited in the application.

[0045] The application further provides a vehicle comprising the sealing strip 10 in any one of the above embodiments. The sealing strip 10 is installed on the back door frame of the vehicle, and the side with the cavity 120 is installed at a position facing the door. Therefore, when the door is opened, the exposed part of the sealing strip 10 is shielded from the trace of the skeleton 200 by using the cavity 120, so that the vehicle is more aesthetically pleasing. Illustratively, the sealing strip 10 can also be applied to other occasions where the sealing strip 10 is needed, such as the edge of the side door, the side door frame, the trunk door, etc. of the vehicle, and the application does not limit the use position of the sealing strip 10 on the vehicle.

[0046] In one embodiment, the vehicle further comprises a rear bumper 30, the bending portion 141 of the flange structure 140 abuts against the rear bumper 30 away from the end of the main body portion 100, and there is a certain interference amount L2 between the end and the rear bumper 30, so that the flange structure 140 can shield the gap at the position where the sealing strip 10 cooperates with the rear bumper 30. Illustratively, L2 ranges from 0.5 mm to 2 mm.

[0047] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, but it should be understood that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.

[0048] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
