[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Reference Figure 1 - Figure 8 The utility model provides an embodiment: a new rear door B-pillar sealing strip, including a frame 1, an outer wall of the frame 1 is fixedly connected with a mounting protrusion 2, and the mounting protrusion 2 is arranged in the area where the AA section is located.

[0047] Reference Figure 7 - Figure 19 A sealing mechanism 3 is provided on the outside of the mounting protrusion 2 and the inside of the frame 1. The sealing mechanism 3 includes a mounting component 31 and a functional component 32. The sealing mechanism 3 is connected to the frame 1 through the setting of the mounting component 31, and the sealing and sound insulation effects are ensured through the setting of the functional component 32.

[0048] Reference Figure 1 、 Figure 7 and Figure 8The cam 313 of the second end 314 is provided with a screw thread 316 which is fixed on the top of the cam 316 so as to prevent the cam 316 from falling off and the cam 316 from falling off.

[0049] Reference Figure 1 、 Figure 7 and Figure 8 The interior of the mounting strip 311 is provided with a mounting groove 314, and the inner wall of the mounting groove 314 is fixedly connected with an aluminum strip 315. The setting of the aluminum strip 315 ensures that the mounting strip 311 is not easily deformed. The setting of the mounting groove 314 ensures that the mounting strip 311 can be deformed to a certain extent. Through the combination of the two, it is ensured that the mounting strip 311 cannot change in a large shape, but can be deformed in a small range, thereby ensuring that the mounting strip 311 can better achieve a fit with the frame 1 and the car door, but is not easy to produce deformation that affects use as the use time increases. The size of the mounting groove 314 is larger than the size of the aluminum strip 315, and the aluminum strip 315 is set in the middle of the mounting groove 314.

[0050] Reference Figure 9 - Figure 14 The outer wall of the mounting strip 311 is fixedly connected with a tape 316. The setting of the tape 316 ensures that the mounting strip 311 can be directly connected to the frame 1. The inner wall of the mounting strip 311 is provided with a mounting hole 317. The setting of the mounting hole 317 ensures that the mounting strip 311 can be connected to other fixed objects, thereby ensuring the fixing effect. The tape 316 and the mounting hole 317 are set at different positions.

[0051] Reference Figure 1 and Figure 3 An embedded part 4 is provided on the inner side of the skeleton 1, and the embedded part 4 is fixedly connected to the skeleton 1. Through the setting of the embedded part 4, it is ensured that the shape of the skeleton 1 is not easily changed. The embedded part 4 is set at the corner of the skeleton 1.

[0052] Reference Figure 3 - Figure 6 、 Figure 9 、 Figure 11、 Figure 13 and Figure 16 - Figure 19 The mounting strip 311 is connected to the embedded part 4 through the buckle 1 5, and the mounting strip 311 is connected to the frame 1 through the buckle 2 6. Both the buckle 1 5 and the buckle 2 6 have shape memory. Through the setting of shape memory, it is ensured that the buckle 1 5 and the buckle 2 6 can be reset according to their own tension after installation, thereby achieving the fixing effect of the mounting strip 311 through its expansion part.

[0053] Reference Figure 8 、 Figure 10 、 Figure 12 and Figure 14 The functional component 32 includes a sealing cloak 321. The material of the sealing cloak 321 is set to ethylene-propylene-diene copolymer sponge. Through the setting of the material, it is ensured that the sealing cloak 321 can resist ultraviolet radiation, oxidation and climate change, has good corrosion resistance, and has excellent elasticity and elastic recovery. The outer wall of the sealing cloak 321 is fixedly connected to the outer wall of the mounting strip 311. The outside of the sealing cloak 321 is coated with an extrusion coating. The initial shape of the sealing cloak 321 is arc-shaped, and the extrusion point of the sealing cloak 321 is set in the middle of the sealing cloak 321.

[0054] Working principle: When using, when installing the sealing mechanism 3, the staff first installs the mounting strip 311 on the inner side of the frame 1 through the tape 316, and then the staff uses the buckle 1 5 and the buckle 2 6 to fix the other areas of the mounting strip 311 except the AA area to the frame 1 or the embedded part 4, thereby ensuring that the mounting strip 311 is not easy to fall off during use.

[0055] After the mounting strip 311 is well fixed to the frame 1, the staff manually installs the concave surface of the mounting strip 311 on the outside of the mounting protrusion 2. Since the aluminum strip 315 is provided inside the mounting strip 311, the concave shape of the mounting strip 311 is not easy to change. After the installation is completed, the surface of the mounting protrusion 2 is squeezed by the protruding block 312, so that the mounting protrusion 2 can contact the surface with the anti-slip groove 313.

[0056] When the mounting strip 311 is subjected to a small natural force, such as wind, causing the mounting strip 311 to move away from the mounting protrusion 2, the mounting protrusion 2 is squeezed by the protruding block 312 and obstructed by the anti-slip groove 313, so that the mounting strip 311 is subjected to greater resistance, thereby ensuring that the mounting strip 311 is not easily fallen off.

[0057] When the equipment is used normally, since the force point of the sealing cloak 321 is set in the middle, and since the shape of the sealing cloak 321 is set to be arc-shaped, when the middle is subjected to force, the middle part of the sealing cloak 321 can move toward the direction close to the installation strip 311, while the left and right ends still maintain the same fit with the installation strip 311 due to the force, so better sealing can be achieved.

[0058] When the force on the sealing cloak 321 is released, the sealing cloak 321 has good elastic recovery force due to its material setting, so the sealing cloak 321 can recover under its own action, and because the shape of the sealing cloak 321 is arc-shaped, when strong winds occur, the seam can blow through the arc surface of the sealing cloak 321, and it is not easy to cause it to deform.

[0059] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
