[0026] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] The embodiment of the present application provides a frameless door B-pillar sealing structure and an automobile thereof, which can solve the problem of reverse flipping of the lip when the glass is lifted and lowered in the related art.

[0028] Frameless doors are increasingly widely used in automobiles, and the requirements for design and quality are also getting higher and higher. The frameless door sealing strip is a key component in the frameless door. In the actual use process, there are still some problems with the B-pillar glass guide groove sealing strip, such as the flipping of the lip when the glass is lifted and lowered, the appearance problem of the cooperation between the joint angle and the trim panel, and the poor assembly convenience of the lower joint angle 12, etc. All these need better designs to solve.

[0029] Regarding the problem of reverse flipping of the lip when the glass is lifted and lowered, refer to Figures 1 to 4 , in the first aspect, the embodiment of the present application provides a frameless door B-pillar sealing structure, which includes: a B-pillar trim panel 2, a B-pillar glass guide groove assembly 1. The B-pillar glass guide groove assembly 1 includes a B-pillar strip 10. The B-pillar strip 10 includes a main body structure 100 and a lip structure. The B-pillar glass guide groove assembly 1 is clamped to the B-pillar trim panel 2 through the main body structure 100, and is used to abut against the door glass 3 through the lip structure. Wherein, the main body structure 100 is connected to the lip structure and encloses to form an avoidance groove with an opening structure. The end of the lip structure away from the main body structure 100 bends towards the opening structure and inclines towards the inner side of the avoidance groove.

[0030] In the present application, through the main body structure 100 and the lip structure provided in the B-pillar glass guide groove assembly 1, the main body structure 100 provides support, and the lip structure is compressed and cooperated with the door glass 3 to realize functions such as supporting the lifting and lowering of the glass and sealing. And when designing the lip structure, the inclination direction of the lip structure is determined to ensure that when the door glass 3 is compressed, the lip structure always flips and compresses towards the inner side of the avoidance groove, which can prevent the reverse flipping of the lip structure under the condition of overpressure of the glass, thereby ensuring the reliability of the overall function.

[0031] Among them, the B-pillar glass guide groove assembly 1 is made of rubber material. In this embodiment, EPDM rubber is selected. EPDM rubber has excellent ozone resistance, weather resistance, heat resistance, acid and alkali resistance, and water vapor resistance.

[0032] On the basis of the above embodiment, in this embodiment, the lip structure includes: an outer lip 101 and an inner lip 102.

[0033] First of all, it should be noted that the main structure 100 is snap-connected to the B-pillar trim panel 2. When the door glass 3 compresses the B-pillar glass guide groove assembly 1, the outer lip 101 is squeezed between the B-pillar trim panel 2 and the door glass 3; the inner lip 102 is only squeezed by the door glass 3. One end of the inner lip 102 is connected to the main structure 100. When being squeezed by the door glass 3, if the structural design is unreasonable, the risk of reverse flipping will be relatively large.

[0034] Therefore, in this embodiment, in order to prevent the outer lip 101 and the inner lip 102 from reversing and flipping, the inner lip 102, the outer lip 101 and the main structure 100 are enclosed to form an avoidance groove with an opening structure. That is to say, the ends of the inner lip 102 and the outer lip 101 do not contact each other, forming an opening structure. In this application, the purpose of setting the avoidance groove is to provide a space for the inner lip 102 and the outer lip 101 to flip and deform.

[0035] Specifically, the outer lip 101 is connected to one end of the main structure 100 close to the B-pillar trim panel 2, and the end of the outer lip 101 away from the main structure 100 is set to bend towards the opening structure; the inner lip 102 is connected to one end of the main structure 100 away from the B-pillar trim panel 2, and the inner lip 102 is set to incline from the end close to the B-pillar trim panel 2 towards the side of the B-pillar trim panel 2, that is, towards the side of the B-pillar trim panel 2.

[0036] That is to say, the inclination directions are determined when the outer lip 101 and the inner lip 102 are in the natural state. When the outer lip 101 and the door glass 3 are compressed along the vehicle X direction, and the inner lip 102 and the door glass 3 are compressed along the vehicle Y direction, both can compress the outer lip 101 and the inner lip 102 into the inside of the avoidance groove.

[0037] Furthermore, wear-resistant coatings are sprayed on the surfaces of the outer lip 101 and the inner lip 102 to improve the wear resistance of the outer lip 101 and the inner lip 102. After the wear-resistant coatings are cured, a dense protective layer is formed, which can effectively resist long-term friction, scratching and environmental erosion, and significantly improve the surface wear resistance and service life of the outer lip 101 and the inner lip 102.

[0038] On the basis of the above embodiment, in this embodiment, a hinge groove 1020 is opened on the inner wall of the end of the inner lip 102 close to the B-pillar trim panel 2. The opened hinge groove 1020 can effectively provide guidance and movement space for the inner lip 102 when bending operations are required. When bending operations are required for the inner lip 102, the hinge groove 1020 can guide the inner lip 102 to deform along a predetermined path, facilitating the bending action of the inner lip 102. Therefore, the inclination direction of the inner lip 102 is determined: it inclines towards the B-pillar trim panel 2 from the root upwards.

[0039] Moreover, in order to further prevent the inner lip 102 from reversing and flipping, a first boss 103 is provided on the surface of one end of the main body structure 100 close to the inner lip 102. Among them, the first boss 103 protrudes away from the avoidance groove. The side of the first boss 103 close to the B-pillar trim panel 2 is a limiting surface. When the vehicle door glass 3 presses against the inner lip 102 and the main body structure 100, the first boss 103 is used to abut against the B-pillar trim panel 2. By limiting with the B-pillar trim panel 2 through the first boss 103, it is ensured that when the vehicle door glass 3 over-presses the inner lip 102, the inner lip 102 still flips and compresses in the designed direction.

[0040] Therefore, through the design of the above structure, it is prevented that the inner lip 102 reverses and flips under the condition of over-pressing of the vehicle door glass 3, thereby ensuring the reliability of the overall function.

[0041] On the basis of the above embodiments, in this embodiment, in order to ensure the mating reliability and assembly convenience between the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2, a series of structural designs are carried out on the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2:

[0042] A clamping groove is provided on the B-pillar trim panel 2, and one end of the main body structure 100 is clamped inside the clamping groove.

[0043] Among them, the B-pillar trim panel 2 includes: a trim panel body 20 and a trim panel skeleton 21. After the trim panel skeleton 21 is connected to the trim panel body 20, one end of the trim panel skeleton 21 extends away from the trim panel body 20, so that a clamping groove is formed between the trim panel body 20 and the trim panel skeleton 21. The setting of the clamping groove provides a clamping space for the main body structure 100, and can ensure that the main body structure 100 is clamped between the trim panel body and the trim panel skeleton 21 to improve the fastening between the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2.

[0044] In addition, in order to further improve the fastening between the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2, an assembly lip 104 is provided on one side of the main body structure 100, and a skeleton boss 210 is fixedly arranged corresponding to and mating with the inner wall of the clamping groove.

[0045] In this embodiment, two skeleton bosses 210 are provided inside the clamping groove. Correspondingly, two assembly lips 104 are also provided on the main body structure 100. Since the skeleton bosses 210 protrude from the inner wall of the clamping groove towards the main body structure 100, two concave structures are formed on the trim panel skeleton 21, and the two assembly lips 104 respectively extend into the concave structures, and the assembly lips 104 are abutted against the skeleton bosses 210, thereby further ensuring the fastening of the connection between the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2.

[0046] In addition, a decorative plate boss 200 is fixed on the inner wall of the clamping groove, and a second boss 105 is provided on one side of the main structure 100. The decorative plate boss 200 protrudes from the inner wall of the clamping groove toward the side of the main structure 100, and the second boss 105 protrudes from the surface of the main structure 100 toward the side close to the decorative plate boss 200 and abuts against the decorative plate boss 200.

[0047] In this embodiment, the main structure 100 can be snapped into place with the B-pillar decorative panel 2 by means of the matching arrangement of the assembly lip 104 , the frame boss 210 , the decorative panel boss 200 , and the second boss 105 .

[0048] On the basis of the above embodiments, in this embodiment, the B-pillar glass run channel assembly 1 further includes an upper corner 11 and a lower corner 12 , wherein the upper corner 11 is connected to one end of the B-pillar strip 10 , and the lower corner 12 is connected to the other end of the B-pillar strip 10 .

[0049] The upper connecting angle 11 and the lower connecting angle 12 are welded to the B-pillar strip 10 to form an integrated structure.

[0050] See also Figure 1 As shown, in Figure 1 Two upper corners 11 are arranged on both sides above the middle B-pillar strip 10 , and a lower corner 12 is arranged below the B-pillar strip 10 .

[0051] The lower connecting angle 12 of the B-pillar glass guide channel assembly 1 entirely covers the B-pillar decorative panel 2. The traditional form uses a snap-on connection in the middle, which takes a long time to assemble and has low appearance assurance. Therefore, in the present application, the matching point between the lower connecting angle 12 and the B-pillar decorative panel 2 is optimized.

[0052] For details, see Figure 4 As shown, the lower corner 12 is located at one end of the decorative plate body 20 and covers the surface of the decorative plate frame 21. Figure 4 It can be seen that a slot is provided between the decorative plate body 20 and the decorative plate frame 21, and the slot is used for the lower corner 12 to be engaged. In this embodiment, an assembly rib 120 is extended from one end of the lower corner 12, and the shape and structure of the assembly rib 120 are adapted to the shape and structure of the slot, so that the assembly rib 120 is engaged inside the slot.

[0053] In addition, in order to ensure the fastening of the lower connecting corner 12 and the B-pillar trim panel 2, a third boss 121 is provided at one end of the lower connecting corner 12. The third boss 121 is adjacent to the assembly rib 120 and abuts against the trim panel body 20. The assembly rib 120 designed on the lower connecting corner 12 is snapped into the card slot formed by the trim panel body 20 and the trim panel skeleton 21. Coupled with the third boss 121 designed on the upper side of the upper connecting corner 11, it can ensure the reliability and stability of the clearance surface difference between the lower connecting corner 12 and the trim panel body 20, and at the same time improve the convenience of assembly.

[0054] The above is for the mating connection between one end of the lower connecting corner 12 and the B-pillar trim panel 2. Further, a structure is also provided at the other end of the lower connecting corner 12 to make the connection between the lower connecting corner 12 and the B-pillar trim panel 2 more precise and the assembly more convenient.

[0055] In this embodiment, the other end of the lower connecting corner 12 is bent towards the side of the trim panel skeleton 21 to form an assembly hook 122, and the trim panel skeleton 21 is snapped into the assembly hook 122. Specifically, since the assembly hook 122 is bent, an installation groove for the trim panel skeleton 21 to be snapped into is formed between the assembly hook 122 and the lower connecting corner 12. Its shape and structure are adapted to the shape and structure of the end of the trim panel skeleton 21, and the assembly hook 122 can wrap around the lower end of the trim panel skeleton 21.

[0056] Further, an inclined angle guiding structure is provided on one side of the inner wall of the assembly hook 122 to make the size of the opening of the installation groove larger than the size of the bottom end of the installation groove, facilitating the assembly of the trim panel skeleton 21.

[0057] To sum up, in this application, through the optimization of the cross-section structure, the reverse flipping of the inner lip 102 is prevented under the condition of overpressure of the vehicle door glass 3, thus ensuring the reliability of the overall function; the lower connecting corner 12 and the B-pillar trim panel 2 are used in combination with a cross-section snap connection, thus ensuring the mating reliability between the B-pillar glass guide groove assembly 1 and the B-pillar trim panel 2, and also greatly improving the assembly convenience of the general assembly.

[0058] In a second aspect, an embodiment of the present application provides an automobile, which includes: the frameless door B-pillar sealing structure provided in any one of the above embodiments of the present application.

[0059] In this application, through the main body structure 100 and the lip structure provided in the B-pillar glass guide groove assembly 1, support is provided by the main body structure 100, and functions such as supporting the lifting and sealing of the glass are realized through the compression fit of the lip structure and the vehicle door glass 3. And when designing the lip structure, the inclination direction of the lip structure is determined to ensure that when the vehicle door glass 3 is compressed, the lip structure always flips and compresses towards the inside of the avoidance groove, preventing the reverse flipping of the lip structure under the condition of glass overpressure, thus ensuring the reliability of the overall function.
