[0002] Frameless door sealing structures are typically installed on the side walls of the door opening to provide a seal with the door. When the vehicle door is closed, both the door body and the door glass panel abut against this frameless door sealing structure, achieving a seal between the door and the side wall of the door opening. However, in related technologies, the seal between the door and the side wall of the door opening via the frameless door sealing structure is poor. Utility Model Content

[0003] The purpose of this disclosure is to provide a frameless door sealing structure, a body assembly, and a vehicle, which improves the sealing performance between the door and the sidewall of the body door opening, resulting in better sealing performance between the door and the sidewall of the body door opening.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, an X-direction is defined for the frameless door sealing structure, where X-direction is the width direction of the second abutment portion. Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0031] The inventors discovered that frameless door sealing structures are typically installed on the side walls of the door openings of the vehicle body to cooperate with the door for sealing. When the vehicle door is closed, both the door body and the door glass panel abut against the frameless door sealing structure, which can achieve a seal between the door and the side walls of the door openings of the vehicle body, and prevent water from outside the vehicle from entering the passenger compartment through the gap between the door and the side walls of the door openings of the vehicle body. The higher the compressive load of the frameless door sealing structure, the better its sealing performance and the higher the seal between the door and the frameless door sealing structure. In related technologies, to improve the seal between the door and the side wall of the door opening on the vehicle body, the compressive load of the frameless door sealing structure is usually increased within an appropriate range. However, for frameless doors, a large compressive load on the frameless door sealing structure can cause a large rebound force on the door against the sealing structure. This can cause the door glass panel to deviate from its preset trajectory when raised, preventing it from smoothly entering the sealing groove of the glass panel sealing strip on the vehicle body side. This affects the seal between the glass panel and the vehicle body side, resulting in poor sealing between the door and the side wall of the door opening through the frameless door sealing structure. How to improve the seal between the door and the side wall of the door opening without affecting the entry of the door glass panel into the groove, thereby improving the overall seal between the door and the side wall of the door opening, is a technical problem that needs to be solved.

[0032] It should be understood that the glass panel sealing strip is located on the side panel of the roof. When the door is closed, the door glass panel rises and abuts against the sealing strip. The glass panel insertion process is as follows: with the door closed, the door glass panel rises, abuts against the sealing strip, and continues to move a predetermined distance, causing the sealing strip to compress and deform, thus forming a sealing groove. The door glass panel is inserted into this sealing groove and held by the sealing strip. However, the frameless door sealing structure has a large compressive load, which causes a large rebound force on the door glass panel abutting against the frameless door sealing structure. This can cause the door glass panel to deviate from its predetermined trajectory when rising, preventing it from smoothly abutting against the predetermined area of ​​the sealing strip and thus preventing the door glass panel from smoothly entering the groove.

[0033] To at least partially solve the aforementioned technical problems, this disclosure provides a frameless door sealing structure 10, such as... Figures 1 to 7 As shown, the frameless door sealing structure 10 is disposed on the side wall of the door opening 30 of the vehicle body, and is used to cooperate with the door 20 for sealing. The door 20 includes a door body 22 and a door glass panel 21. The frameless door sealing structure 10 includes a first sealing section 11 and a second sealing section 12. The first sealing section 11 is used to abut against the door glass panel 21 for sealing, and the second sealing section 12 is used to abut against the door body 22 for sealing. The compressive load of the second sealing section 12 is greater than that of the first sealing section 11.

[0034] In the above embodiment, the compressive load of the second sealing section 12 abutting against the door body 22 is greater than the compressive load of the first sealing section 11 abutting against the door glass panel 21. When the door 20 is closed, the supporting force of the second sealing section 12 abutting against the door body 22 is greater than the supporting force of the first sealing section 11 abutting against the door glass panel 21. Through this arrangement, the sealing performance of the second sealing section 12 is improved, thereby enhancing the sealing performance between the door body 22 and the sidewall of the vehicle body door opening 30, and further improving the waterproof performance between the door body 22 and the sidewall of the vehicle body door opening 30. Furthermore, the compression load of the first sealing section 11 is less than that of the second sealing section 12. The supporting force of the first sealing section 11 when it abuts against the door glass panel 21 is smaller, which can prevent the supporting force of the frameless door sealing structure 10 on the door glass panel 21 from being too large and deviating from the preset trajectory when it is raised. This allows the door glass panel 21 to be inserted into the sealing groove of the glass panel sealing strip 50 when it is raised, so as to ensure the sealing between the door glass panel 21 and the side wall of the body door opening 30. When the sealing between the door body 22 and the side wall of the body door opening 30 and the door glass panel 21 and the side wall of the body door opening 30 are improved, the sealing between the door 20 as a whole and the side wall of the body door opening 30 can be improved, thereby making the sealing between the door 20 and the side wall of the body door opening 30 better.

[0035] It should be noted that the second sealing section 12 of the frameless door sealing structure 10 has a large compressive load. While improving the sealing between the door body 22 and the side wall of the door opening 30, it can also improve the waterproof performance between the door body 22 and the side wall of the door opening 30, thereby increasing the vehicle's wading depth and allowing the vehicle to wade through deeper water.

[0036] In some implementations, such as Figures 4 to 7 As shown, the first sealing section 11 includes a first bubble tube sealing part 111 for abutting against the door glass panel 20, and the second sealing section 12 includes a second bubble tube sealing part 121 for abutting against the door body 22. The compressive load of the second bubble tube sealing part 121 is greater than the compressive load of the first bubble tube sealing part 111. When the door 20 is closed, the first bubble tube sealing part 111 abuts against the door glass panel 21 to seal with the door glass panel 21. The first bubble tube sealing part 111 has a small compressive load, so that the supporting force of the first bubble tube sealing part 111 against the door glass panel 21 is small. While meeting the sealing requirements between the door glass panel 21 and the side wall of the body door opening 30, it can also avoid the first bubble tube sealing part 111 giving the door glass panel 21 too much support force, which would cause the door glass panel 21 to deviate from the preset trajectory when it is raised. The second bubble tube sealing part 121 abuts against the door body 22 to seal with the door body 22. The second bubble tube sealing part 121 has a large compressive load, so that the supporting force of the second bubble tube sealing part 121 against the door body 22 is large, so that the sealing performance between the door body 22 and the side wall of the body door opening 30 is better, and the waterproof performance between the door body 22 and the side wall of the body door opening 30 is also improved.

[0037] The first bubble tube sealing part 111 and the second bubble tube sealing part 121 can be constructed using any suitable structure. For example Figure 4 and Figure 5 As shown, in some embodiments, the first bubble tube sealing part 111 includes a first cavity 114 extending along the extension direction of the first sealing section 11, and the second bubble tube sealing part 121 includes a second cavity 125 extending along the extension direction of the second sealing section 12. A support wall 1252 is provided inside the second cavity 125 to divide the second cavity 125 into at least two second sub-cavities 1251. The cross-sectional area of ​​the second sub-cavities 1251 is smaller than the cross-sectional area of ​​the first cavity 114.

[0038] In the above embodiment, a support wall 1252 is provided in the second cavity 125 to divide the second cavity 125 into at least two second sub-cavities 1251 with a cross-sectional area smaller than that of the first cavity 114. The support wall 1252 in the second cavity 125 can play a supporting role to increase the compressive load of the second bubble tube sealing part 121. When the car door 20 is closed, the second bubble tube sealing part 121 of the second sealing section 12 has a large supporting force against the car door body 22, so as to improve the sealing between the car door body 22 and the side wall of the car body door opening 30, and also improve the waterproof performance between the car door body 22 and the side wall of the car body door opening 30.

[0039] In some embodiments, the number of first cavities 114 provided in the first bubble tube sealing part 111 and the number and cross-sectional area of ​​second sub-cavities 1251 in the second bubble tube sealing part 121 can be set according to actual needs, so that the compression load of the second bubble tube sealing part 121 is greater than the compression load of the first bubble tube sealing part 111.

[0040] In some embodiments, the first bubble tube sealing portion 111 includes a first cavity 114, and / or the second bubble tube sealing portion 121 includes at least two spaced-apart second sub-cavities 1251, each of which has a smaller cross-sectional area than the first cavity 114. The at least two spaced-apart second sub-cavities 1251 are separated by at least one support wall 1252 disposed within the second cavity 125, and the at least one support wall 1252 provides a supporting function to increase the compressive load of the second bubble tube sealing portion 121.

[0041] like Figures 4 to 7 As shown, the first sealing section 11 includes one first cavity 114, and the second bubble tube sealing part 121 includes one second cavity 125. A support wall 1252 is provided in the second cavity 125 to divide the second cavity 125 into two second sub-cavities 1251 with a cross-sectional area smaller than that of the first cavity 114. The support wall 1252 can provide support force to increase the compressive load of the second bubble tube sealing part 121. When the second bubble tube sealing part 121 of the second sealing section 12 abuts against the door body 22, the second bubble tube sealing part 121 provides a larger support force to the door body 22 to improve the sealing performance between the door body 22 and the side wall of the vehicle body door opening 30, thereby improving the waterproof performance between the door body 20 and the side wall of the vehicle body door opening 30.

[0042] In some embodiments, the compression load of the first bubble tube sealing part 111 and the second bubble tube sealing part 121 can be set according to actual needs. For example, the compression load of the first bubble tube sealing part 111 can be 6~7N / 100mm, so that when the first bubble tube sealing part 111 abuts against the door glass panel 21, it can ensure the sealing between the door glass panel 21 and the side wall of the body door opening 30, and also avoid the door glass panel 21 being unable to insert into the sealing groove of the glass panel sealing strip 50 due to excessive support force against the door glass panel 21, which would cause the door glass panel 21 to deviate from the preset trajectory when it is raised.

[0043] It should be noted that when the first bubble tube sealing part 111 abuts against the door glass panel 21, the first bubble tube sealing part 111 will exert a force on the door glass panel 21 towards the outside of the door 20. If this force is too large, it will cause the door glass panel 21 to deviate from the preset trajectory when it rises, making it impossible for the door glass panel 21 to be inserted into the sealing groove of the glass panel sealing strip 50 of the door 20, thus affecting the sealing performance between the door glass panel 21 and the top side wall of the door opening 30. However, by using the first bubble tube sealing part 111 of this disclosure to abut against the door glass panel 21, it is possible to avoid the first bubble tube sealing part 111 exerting too large a supporting force on the door glass panel 21, which would cause the door glass panel 21 to deviate from the preset trajectory when it rises.

[0044] In some embodiments, the compression load of the second bubble tube sealing part 121 can be 10~12N / 100mm, so that the second bubble tube sealing part 121 provides greater support force to the door body 22 when it abuts against the door body 22, thereby improving the sealing performance between the door body 22 and the side wall of the body door opening 30, and thus improving the waterproof performance between the door body 22 and the side wall of the body door opening 30.

[0045] In some embodiments, the second bubble tube sealing portion 121 is provided with at least one protrusion 124 for abutting against the door body 22, and the protrusion 124 extends along the extending direction of the second bubble tube sealing portion 121. With this arrangement, the protrusion 124 abuts against the door body 22, thereby reducing the contact area between the door body 22 and the second sealing section 12, increasing the sealing pressure between the door body 22 and the second sealing section 12, and further improving the sealing performance between the door body 22 and the sidewall of the vehicle body door opening 30, thus further enhancing the waterproof performance between the door body 22 and the sidewall of the vehicle body door opening 30.

[0046] In some implementations, such as Figure 4 and Figure 6As shown, the first sealing section 11 includes a first main body 112 and a first interior trim fitting part 113. The first main body 112 is used to be installed on the side wall of the vehicle door opening 30, and the first interior trim fitting part 113 is used to be installed on the vehicle interior trim panel 60. The first bubble tube sealing part 111 is connected to the first main body 112. The first main body 112 forms a first clamping groove 115. The side panel 40 at the side wall of the vehicle door opening 30 is inserted into the first clamping groove 115, and the first main body 112 is clamped on the side panel 40 at the side wall of the vehicle door opening 30. The vehicle interior trim panel 60 is inserted into a first slot 116 between the first interior trim fitting part 113 and the first main body 112. The first interior trim fitting part 113 is fixedly connected to the vehicle interior trim panel 60 by a first pull rope 117 connected to the first interior trim fitting part 113. Through the above arrangement, the first sealing section 11 of the door sealing structure is fixedly connected to the side wall of the vehicle door opening 30.

[0047] In addition, the first bubble tube sealing part 111 includes a first abutting part 1112 and a first base part 1111 connected to the first abutting part 1112, wherein the first abutting part 1112 is used to abut against the door glass panel 21, and the first base part 1111 is connected to the first main body part 112.

[0048] In some implementations, such as Figures 5 to 7 As shown, the second sealing section 12 includes a second main body 122 and a second interior trim fitting part 123. The second main body 122 is used to be installed on the side wall of the vehicle door opening 30, and the second interior trim fitting part 123 is used to be installed on the vehicle interior trim panel 60. The second bubble tube sealing part 121 is connected to the second main body 122. The second main body 122 has a second clamping groove 126. The side panel 40 at the side wall of the vehicle door opening 30 is inserted into the second clamping groove 126, and the second main body 122 is clamped onto the side panel 40 at the side wall of the vehicle door opening 30. The vehicle interior trim panel 60 is inserted into a second slot 127 between the second interior trim fitting part 123 and the second main body 122. The second interior trim fitting part 123 is fixedly connected to the vehicle interior trim panel 60 by a second pull rope 128 connected to the second interior trim fitting part 123. Through the above arrangement, the second sealing section 12 of the frameless door sealing structure 10 is fixedly connected to the side wall of the vehicle door opening 30.

[0049] In addition, the second bubble tube sealing part 121 includes a second abutting part 1212 and a second base part 1211 connected to the second abutting part 1212, wherein the second abutting part 1212 is used to abut against the door body 22, and the second base part 1211 is connected to the second main body part 122.

[0050] In some embodiments, as described above, the second bubble tube sealing part 121 includes a second abutting part 1212 for abutting and engaging with the door body 22. The number of protrusions 124 may be at least two and are spaced apart along the width direction X of the second abutting part 1212. When the door 20 is closed, at least two protrusions 124 may abut against the door body 22 to further improve the sealing between the door body 22 and the second sealing section 12. Thus, the waterproof performance between the door body 22 and the side wall of the vehicle body door opening 30 can be further improved.

[0051] like Figure 1 As shown, the frameless door sealing structure 10 is installed on the side wall of the door opening 30. The section above the waistline E can be a first sealing section 11, used to abut against the door glass panel 21 when the door 20 is closed. The section below the waistline E can be a second sealing section 12, used to abut against the door body 22 when the door 20 is closed. The waistline E can be set according to the actual coverage area of ​​the door glass panel 21 and the door body 22; there are no restrictions here.

[0052] In addition, the first sealing section 11 and the second sealing section 12 can be integrally formed using a variable cross-section process; or, the first sealing section 11 and the second sealing section 12 can be formed separately, and a connector (corner joint) can be used to connect the two at the connection point.
