Description

Technical Field

[0001] The present invention relates to the technical field of vehicle window components, and in particular to a fully concealed integral flush vehicle door structure. Background Art

[0002] Modern automotive window systems generally utilize a coplanar sealing structure. Its core characteristic is the precise assembly and matching of the sliding glass and the window frame, ensuring a continuous and smooth transition between the glass's outer surface and the frame's interface. Current frameless designs generally include frameless door systems and technologies where the sliding glass is flush with the existing side window frame.

[0003] Among them, in the frameless door system, due to the lack of a window frame structure, the top flush effect cannot be achieved at all. The overall system's waterproof performance and NVH performance are relatively poor, and there are application limitations, such as it cannot be used on large vehicles; at the same time, in the technology of flushing the door movable glass with the existing side window frame, although the side is flush, it is only flush with the side, and the overall appearance is not much different from the visual effect of the conventional frame, and consumers cannot intuitively perceive the difference from traditional models; at the same time, because the door movable glass is flush with the existing side window frame, but at this time there is still a large step matching structure between the top side of the door movable glass and the top window frame, so in terms of the overall visual sense, the abrupt visual separation between the top side of the door movable glass and the top window frame is more intense. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a fully concealed integral flush door structure to solve the problem that the frameless door system and the technology of flushing the door movable glass with the existing side window frame are difficult to achieve the top flush effect. The top step causes a sense of fragmentation in the appearance of the door and the problem of high wind noise.

[0005] To achieve the above objectives, the basic solution of the present invention is as follows: a fully concealed, integrally flush vehicle door structure comprising a movable door glass, a first body side panel, and a B-pillar side window frame, wherein the upper end of the B-pillar side window frame is connected to the first body side panel, a side concealed window frame structure is provided between the side of the movable door glass and the B-pillar side window frame, and the movable door glass is flush with the side of the B-pillar side window frame facing away from the interior of the vehicle;

[0006] A top hidden window frame structure is provided at the first body side panel, and the door movable glass is flush with the side of the first body side panel away from the interior of the vehicle.

[0007] The technical principle of the present invention is as follows: the side hidden window frame structure can cooperate with the door movable glass and the B-pillar side window frame, so that during the lifting process of the door movable glass, the side edge of the door movable glass is opposite to the edge of the B-pillar side window frame, and the door movable glass is flush with the side of the B-pillar side window frame away from the interior of the vehicle; at the same time, the top hidden window frame structure can cooperate with the door movable glass and the first body side panel metal, so that after the door movable glass rises to the top, the top edge of the door movable glass is opposite to the edge of the first body side panel metal, and the door movable glass is flush with the side of the first body side panel metal away from the interior of the vehicle. At this time, the upper edge of the door movable glass, the lower side of the first body side panel metal, the side of the door movable glass and the edge of the B-pillar side window frame are all flush.

[0008] At this time, when looking at the door movable glass, the first body side sheet metal and the B-pillar side window frame from outside the car, the overall appearance is clearly recognizable. The top and sides of the door movable glass are flush with the surrounding structure, making the overall side lines of the car simpler and the user's perception effect more direct and obvious.

[0009] Furthermore, the top hidden window frame structure includes:

[0010] a first guide groove sealing strip, the first guide groove sealing strip being abutted against the lower side of the first body side panel and the top side edge of the door movable glass, wherein the top edge of the door movable glass is opposite to the lower side of the first body side panel;

[0011] a first door and window frame sheet metal, the door and window frame sheet metal being fixedly connected to the first vehicle body side panel sheet metal, and the door and window frame sheet metal being connected to the first guide groove sealing strip;

[0012] The first vehicle door window frame trim is fixedly connected to the first vehicle door window frame sheet metal or the first vehicle body side sheet metal, and the vehicle door window frame trim is connected to the first guide groove sealing strip.

[0013] Through the above arrangement, the first door window frame sheet metal and the first door window frame trim can support the first guide groove sealing strip, so that when the door movable glass rises to the top, the side of the door movable glass close to the interior of the car can cooperate with the first guide groove sealing strip to complete the sealing of the door movable glass and the first body side panel sheet metal, and the sealing structure is simple and reliable; at the same time, compared with the frameless door system, the door movable glass and the first body side panel sheet metal reduce the step structure formed by the bright strip, thereby making the flush fit between the door movable glass and the first body side panel sheet metal smoother, and also reducing the gap between the door movable glass and the first body side panel sheet metal, making the overall side lines of the car further simpler.

[0014] Furthermore, the first guide groove sealing strip includes:

[0015] Sealing strip body;

[0016] a first sealing lip, the first sealing lip being located at an upper side of the sealing strip body and abutting against a lower side of the first vehicle body side panel;

[0017] A plurality of first sealing members are provided, wherein the first sealing member is located on a side of the sealing strip body close to the door movable glass and abuts against the top side edge; the first sealing member is a second sealing lip or a first bubble tube, or a combination of the second sealing lip and the first bubble tube.

[0018] Through the above-mentioned arrangement, the first sealing lip can tightly seal between the first body side sheet metal and the first door window frame sheet metal, making the sealing of the first guide groove sealing strip more reliable and reducing NVH; at the same time, the second sealing lip or the first bubble tube and the combined structure thereof can be adopted in the first sealing component. During manufacturing or application, they can be adaptively selected according to cost and usage requirements. The second sealing lip or the first bubble tube has good sealing, waterproofness and sound insulation when it is in contact with the movable glass of the door.

[0019] Furthermore, the first sealing members are all second sealing lips, and the second sealing lips are arranged in parallel from bottom to top along the side of the sealing strip body close to the door movable glass. The second sealing lips can abut against the side wall of the door movable glass.

[0020] Through the above arrangement, the arrangement of several second sealing lips can achieve multi-level tight abutment during the sealing process with the movable door glass, thereby improving the sealing performance of the top side of the movable door glass and the flush accuracy with the first door window frame sheet metal.

[0021] Furthermore, the first sealing components are all first bubble tubes, which are sequentially arranged from bottom to top along the side of the sealing strip body close to the door movable glass, and can abut against the side wall of the door movable glass.

[0022] Through the above arrangement, the first bubble tube has better elasticity than the second sealing lip, can fit more closely to the surface of the door movable glass, adapt to slight deformation or installation errors during the lifting and lowering process of the door movable glass, and have better tolerance.

[0023] Furthermore, the first sealing member is a combination of a second sealing lip and a first bubble tube. The first bubble tube and the second sealing lip are arranged in sequence from bottom to top along the side of the sealing strip body close to the door movable glass. Both the first bubble tube and the second sealing lip can abut against the side wall of the door movable glass.

[0024] Through the above arrangement, the second sealing lip and the first bubble tube are used in combination, which can combine the advantages of the second sealing lip and the first bubble tube. When the movable glass of the vehicle door moves up, it will preferentially contact the first bubble tube with better elasticity, and then better adapt to the first bubble tube first, and then fit with the second sealing lip in a larger area, taking into account both tolerance and sealing when cooperating with the movable glass of the vehicle door.

[0025] Furthermore, the side hidden window frame structure includes:

[0026] The side sealing strip is installed at the edge of the B-pillar side window frame close to the inner side of the vehicle. The side sealing strip is provided with a second sealing member that can abut against the edge of the door movable glass;

[0027] A second door window frame sheet metal, the second door window frame sheet metal being connected to a B-pillar side window frame;

[0028] A second guide groove sealing strip is installed at the end of the second door window frame sheet metal, and a third sealing member is provided on the second guide groove sealing strip that can be in contact with the edge of the door movable glass on the side close to the interior of the vehicle;

[0029] A limiting guide slider, one end of which is fixedly connected to a side of the door movable glass close to the interior of the vehicle;

[0030] An installation frame is fixedly connected to the second door window frame sheet metal, and a middle portion of the installation frame is concave to form a guide slot for a limit guide slider to slide away from one end of the door movable glass to limit the position;

[0031] The third guide groove sealing strip is installed on the side of the mounting frame away from the edge of the door movable glass. The third guide groove sealing strip is provided with a fourth sealing component that can fit with the edge of the door movable glass close to the inside of the vehicle. The limiting guide slider is located between the third guide groove sealing strip and the second guide groove sealing strip.

[0032] Through the above arrangement, the second door window frame sheet metal can provide stable support for the coordinated installation of the limiting guide slider, the mounting frame and the third guide groove sealing strip. At the same time, the second door window frame sheet metal can cooperate with the second guide groove sealing strip to seal the door movable glass during the lifting process. During the lifting and lowering process of the door movable glass, the side panel sealing strip, the second guide groove sealing strip and the third guide groove sealing strip effectively and accurately seal the edge of the door movable glass from three parts, thereby improving the overall waterproof performance of the side hidden window frame structure and reducing the NVH performance. At the same time, since the limiting guide slider is located between the third guide groove sealing strip and the second guide groove sealing strip, the third guide groove sealing strip and the second guide groove sealing strip can provide stable support and sealing during the lifting and lowering process of the door movable glass, and also ensure stable coordination between the limiting guide slider and the mounting frame. The elasticity of the third guide groove sealing strip and the second guide groove sealing strip can compensate for the coordination tolerance between the limiting guide slider and the mounting frame, thereby improving the overall coordination tolerance of the side hidden window frame structure and improving the quietness and smoothness of the door movable glass during lifting and lowering.

[0033] Furthermore, the edge of the second guide channel sealing strip covers the side of the mounting frame away from the second door window frame sheet metal, and the edge of the third guide channel sealing strip covers the side of the mounting frame away from the second door window frame sheet metal.

[0034] Through the above arrangement, when the door movable glass is lowered, the second guide groove sealing strip and the third guide groove sealing strip jointly cover the edge of the mounting frame, ensuring basic sealing performance while ensuring the simplicity of appearance when the mounting frame is exposed.

[0035] Furthermore, the third sealing member is a third sealing lip or a second bubble tube, and the fourth sealing member is a fourth sealing lip or a third bubble tube.

[0036] Through the above arrangement, during the production of the third and fourth seals, the sealing lip structure or the bubble tube structure can be selected according to the needs, and both can be adapted to the side hidden window frame structure, and the side hidden window frame structure has better adaptability.

[0037] Furthermore, the side hidden window frame structure also includes:

[0038] a second door window frame trim panel, one side of the second door window frame trim panel being fixedly connected to the second door window frame sheet metal, and the other side of the second door window frame trim panel being installed between the third guide groove sealing strip and the fourth sealing member;

[0039] A second body side panel, the second body side panel being fixedly connected to a B-pillar side window frame;

[0040] A body door frame sealing strip, the body door frame sealing strip being installed on the side of the second body side panel, and the body door frame sealing strip being provided with a fifth sealing member abutting against the second door window frame trim panel;

[0041] The door sealing strip is installed on the second door window frame sheet metal near the second body side sheet metal. The door sealing strip is provided with a sixth sealing member that can offset the second body side sheet metal. The door sealing strip is located between the side sealing strip and the body door frame sealing strip.

[0042] Through the above arrangement, the third guide groove sealing strip and the fourth sealing member cover the side of the second door window frame trim. When the second door window frame trim is exposed, the appearance structure is simpler; at the same time, the second body side sheet metal can be more closely sealed with the second door window frame trim and the second body side sheet metal through the body door frame sealing strip and the door sealing strip, thereby improving the fit between the door and the body and further reducing NVH; at the same time, the first guide groove sealing strip, the second guide groove sealing strip, the third guide groove sealing strip, the body door frame sealing strip and the door sealing strip can stably seal the door movable glass after it rises in multiple angles and structures, forming a multiple sealing structure, thereby ensuring the sealing performance of the door movable glass after it rises.

[0043] Furthermore, the inner wall of the guide slot of the mounting frame is covered with a wear-resistant part, which is in sliding contact with the end of the limiting guide slider; the wear-resistant part and the mounting frame are integrally formed, or the wear-resistant part and the mounting frame are compositely formed.

[0044] Through the above-mentioned setting, the wear-resistant part can slide and cooperate with the end of the limit guide slider, reduce the static friction between the end of the limit guide slider and the mounting frame, reduce the blockage when the movable glass of the car door is raised and lowered, and the lifting and lowering of the movable glass of the car door is smoother and quieter, and the service life of the mounting frame and the limit guide slider is extended.

[0045] Furthermore, the B-pillar side window frame is side glass or side trim.

[0046] Through the above setting, when the B-pillar side window frame is side glass, the door movable glass and the B-pillar side window frame constitute an overall glass structure with obvious appearance recognition, achieving the effect of no visible window frame after opening the door. The overall side lines are simpler and the user perception effect is more direct and obvious. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic third sealing lip 405 and the third bubble tube 415 support the stable sliding fit between the limiting guide slider 410 and the mounting frame 411 and the stable lifting and lowering guide, so that the tolerance of the overall matching system is better.

[0065] When the door movable glass 10 continues to move upward to the top hidden window frame structure 50, the side surface of the door movable glass 10 close to the interior of the vehicle is in contact with the first sealing member on the first guide groove sealing strip 501, and the upper edge of the door movable glass 10 is flush with the upper side of the first body side panel 30, so that the tops of the door movable glass 10 and the first body side panel 30 are flush, the bright strips on the first body side panel 30 are reduced, the gap between the door movable glass 10 and the first body side panel 30 is narrowed, and the overall side lines of the vehicle are simpler; at the same time, since the B-pillar side window frame 20 is side glass, the door movable glass 10 and the B-pillar side window frame 20 constitute an integral glass structure with obvious appearance recognition, achieving the effect of no visible window frame after the door is opened, the overall side lines are simpler, and the user perception effect is more direct and obvious.

[0066] In the above process, the first guide groove sealing strip 501, the second guide groove sealing strip 404, the third guide groove sealing strip 414, the vehicle body door frame sealing strip 421 and the vehicle door sealing strip 422 can stably seal the vehicle door movable glass 10 after it rises in multiple angles and structures, forming a multiple sealing structure, thereby ensuring the sealing performance of the vehicle door movable glass 10 after it rises, and also improving the waterproof performance and NVH performance of the overall system.

[0067] When the door movable glass 10 is lowered, the second guide groove sealing strip 404 and the third guide groove sealing strip 414 jointly cover the edge of the mounting frame 411 and contact the wear-resistant part 413, while ensuring basic sealing performance, ensuring the simplicity of appearance when the mounting frame 411 is exposed.

[0069] The difference between Example 2 and Example 1 is as follows: Figure 3 As shown, the difference is that the third sealing component in the second guide groove sealing strip 404 is the second bubble tube 406, and at the same time, the wear-resistant component 413 and the installation frame 411 are compositely formed.

[0070] When a fully concealed integral flush door structure is used in this embodiment, the second bubble tube 406 is softer due to its hollow structure compared to the third sealing lip 405 in Example 1, and can fit more closely to the surface of the movable door glass 10, adapting to slight deformations or installation errors during the lifting and lowering process of the movable door glass 10, thereby improving tolerance. At the same time, when the movable door glass 10 is frequently raised and lowered, the elasticity of the second bubble tube 406 can maintain a stable seal, reduce gaps caused by vibration, and improve its sealing performance, thereby blocking more external noise (such as wind noise and tire noise) and improving the quietness of the vehicle interior.

[0071] At the same time, the second bubble tube 406 can cooperate with the third bubble tube 415 on the third guide groove sealing strip 414. The second bubble tube 406 and the third bubble tube 415 cooperate to improve the effect of reducing NVH and improve the matching tolerance between various structures.

[0072] At the same time, since the wear-resistant part 413 and the mounting frame 411 are compositely formed, the fit between the wear-resistant part 413 and the mounting frame 411 is better. When the limiting guide slider 410 slides in the guide groove 412, the fit between the limiting guide slider 410 and the wear-resistant part 413 is also better.

[0073] Example 3

[0074] The difference between Example 3 and Example 1 is as follows: Figure 4 As shown, the difference is that the first sealing component in the first guide groove sealing strip 501 is two first bubble tubes 504, and the two first bubble tubes 504 are arranged in sequence from bottom to top along the side of the sealing strip body close to the vehicle door movable glass 10, and the hollow contour area of the lower first bubble tube 504 is larger than the hollow contour area of the upper first bubble tube 504.

[0075] When a fully concealed integral flush door structure in this embodiment is in use, the two first bubble tubes 504 have better elasticity and sealing properties than the combined structure of the first bubble tube 504 and the second sealing lip 503 in Example 1, and are more conducive to elastically pressing against the side of the door movable glass 10 close to the interior of the vehicle, and the tolerance of the two first bubble tubes 504 and the door movable glass 10 in their cooperation is better.

[0076] At the same time, the first bubble tube 504 located at the lower side can be more tightly fitted with the surface of the door movable glass 10 , thereby improving the tightness of the fit between the top of the door movable glass 10 and the first body side panel 30 .

[0077] Example 4

[0078] The difference between Example 4 and Example 1 is as follows: Figure 5 As shown, the difference is that the first sealing component in the first guide groove sealing strip 501 is three second sealing lips 503, and the three second sealing lips 503 are arranged in parallel from bottom to top along the side of the sealing strip body close to the vehicle door movable glass 10. The three second sealing lips 503 can all be against the side wall of the vehicle door movable glass 10.

[0079] When a fully concealed integral flush door structure in this embodiment is in use, the three second sealing lips 503 have a larger contact surface against the surface of the door movable glass 10 than the combined structure of one first bubble tube 504 and one second sealing lip 503 in Example 1, and the sealing effect is also very good, which can provide effective sealing between the door movable glass 10 and the first body side panel 30.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
