Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, specifically to a rear door C-pillar window frame assembly and a vehicle. Background Technology

[0002] With the continuous development and progress of the automotive industry, perceived quality, vehicle noise, vibration, and comfort have received significant attention. The main function of the door frame groove is to ensure a tight seal between the door glass and the window during operation, providing waterproofing, dustproofing, and windproofing, while also facilitating smooth and noiseless window operation. Current technology, in an effort to reduce vehicle weight and costs, has eliminated the rear door C-pillar roll-fit window frame guide rail. However, this has led to issues such as wind noise, durability, and increased noise during window operation. Summary of the Invention

[0003] The purpose of this application is to provide a rear door C-pillar window frame assembly and vehicle that can achieve good sealing performance, noiseless window operation, and meet the requirements for vehicle lightweighting.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a rear door C-pillar window frame assembly, comprising:

[0006] The C-pillar window frame body includes an outer window frame panel and an inner window frame panel spaced apart along the thickness direction. A mounting part is connected between the inner window frame panel and the outer window frame panel on the side facing the glass. The mounting part has a groove facing the glass opening.

[0007] The grooved component includes a grooved body connected to a slide rail, the grooved body having a receiving groove facing an opening in the glass, the grooved body also including an inner lip and an outer lip located at the opening of the receiving groove, the outer lip including a connected first connecting portion and a second connecting portion, the first connecting portion extending to the receiving groove, the second connecting portion extending to extend out and abut against the outer panel of the window frame, the inner lip including a connected third connecting portion and a fourth connecting portion, the third connecting portion extending to the receiving groove, the first connecting portion and the third connecting portion for abutting against the glass surface extending into the receiving groove, and the fourth connecting portion extending out to abut against the inner panel of the window frame.

[0008] The above-mentioned technical means achieve good sealing effect, noiseless window operation, and meet the requirements for lightweighting the whole vehicle.

[0009] In one optional embodiment, along the extension direction of the groove, the groove component includes an upper groove section, a middle groove section, and a lower groove section connected together. The surface of the second connecting portion located at the upper groove section away from the groove body is an arc-shaped surface, the surface of the second connecting portion located at the lower groove section away from the groove body is an inclined slope, and the surface of the second connecting portion located at the middle groove section away from the groove body is a transition surface that connects the arc-shaped surface and the inclined surface.

[0010] The above-mentioned technical means can effectively avoid the problem of friction and abnormal noise caused by the glass coming into contact with it during the rising process.

[0011] In one alternative embodiment, the cross-section of the trough body is U-shaped, and the trough body includes a bottom wall and side walls, with the side walls located in the upper section of the trough being at least partially composed of metal fiber filaments.

[0012] By employing the aforementioned technical means, we can prevent the upper section of the groove from shrinking and deforming due to changes in the external environment (especially temperature), which could lead to poor matching between the outer lip and the outer panel of the window frame, and consequently, problems such as gaps.

[0013] In one alternative embodiment, in the lower section of the groove member, along the extending direction of the second connecting part, one end of the second connecting part abuts against the surface of the outer panel of the window frame away from the inner panel of the window frame, and the other end is provided with an abutting protrusion protruding from the first connecting part, the abutting protrusion being used to abut against the glass.

[0014] The above-mentioned technical means can effectively prevent wind noise generated during vehicle operation.

[0015] In one optional embodiment, the mounting part has a U-shaped plate structure in cross-section. The mounting part has first limiting protrusions protruding into the groove on both sides along the thickness direction. The outer side of the groove body has a second limiting protrusion extending outward. The second limiting protrusion is an elastic member with deformability. The second limiting protrusion abuts against the first limiting protrusion to connect the groove member to the groove.

[0016] The above-mentioned technical means are combined with a simple structure that is easy to assemble and has high connection stability, preventing detachment.

[0017] In one alternative embodiment, the groove components in the upper and lower sections of the groove are at least partially prepared using a slip material co-extrusion process to form a wear-resistant layer.

[0018] By employing the aforementioned technical means, the co-extrusion process of the slip material makes the surface that comes into contact with the glass more wear-resistant, avoiding the coating peeling caused by traditional coatings, and ensuring that the slip groove body has good wear resistance.

[0019] In one alternative embodiment, the mounting part is provided with an opening communicating with the slide groove, and the opening is located at a position that mates with the middle section of the slide groove.

[0020] The above-mentioned technical means are used to prevent material accumulation and wrinkling deformation during the roller pressing and bending process, which would affect the assembly of the felt trough body.

[0021] In one optional embodiment, a window frame reinforcement is further included, which is fixedly connected to the inner panel of the window frame on the side facing the outer panel of the window frame, and the mounting part is fixedly connected to the outer panel of the window frame and the window frame reinforcement at both ends in the thickness direction, respectively.

[0022] Through the above technical means, the C-pillar window frame body is guaranteed to have high strength while minimizing the increase in weight, thus meeting the lightweight requirements of the whole vehicle.

[0023] In one alternative embodiment, the outer panel of the window frame, the window frame reinforcement, the inner panel of the window frame, and the mounting part are welded and fixed.

[0024] The above-mentioned technical means have further improved the strength of the C-pillar window frame body of the sheet metal parts.

[0025] Secondly, embodiments of this application also provide a vehicle including a rear door C-pillar window frame assembly as described above.

[0026] The beneficial effects of this application are as follows: Based on its cooperation with the sliding groove, the grooved component, through its inner and outer lips, ensures that the first and third connecting parts located in the receiving groove are positioned on either side of the glass in the thickness direction, utilizing their own deformation capacity to abut against the glass surface. Furthermore, the C-pillar window frame has been redesigned, resulting in a simpler structure for the inner and outer window frame panels and the mounting part, meeting the requirements for vehicle lightweighting. The positions and shapes of the grooved components on the inner and outer window frame panels and the mounting part are relatively simple. The inner and outer lips extend through the second and fourth connecting parts to abut against the corresponding outer and inner window frame panels, ensuring good installation stability and sealing. Therefore, the above-mentioned mating structure provides good sealing performance, eliminates abnormal noise during window operation, and meets the requirements for vehicle lightweighting.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] Figure 1 This diagram illustrates the structure of a rear door C-pillar window frame assembly and its cooperation with a vehicle door, according to an embodiment of this application. Figure 2 This is an exploded view of the C-pillar window frame body of a rear door C-pillar window frame assembly provided in an embodiment of this application. Figure 3 This illustration shows a structural diagram of the groove 2 in a rear door C-pillar window frame assembly provided in an embodiment of this application. Figure 4 This diagram illustrates the structural features of the corner joint in the groove component of a rear door C-pillar window frame assembly according to an embodiment of this application.

[0038] like Figures 1 to 4 As shown, this application embodiment provides a rear door C-pillar window frame assembly, which is used in the vehicle body and is fixedly connected to the rear door outer panel 4, which will not be described in detail here.

[0039] The rear door C-pillar window frame assembly includes a C-pillar window frame body 1, comprising an outer window frame panel 11 and an inner window frame panel 12 spaced apart along the thickness direction. A mounting part 13 is connected between the inner window frame panel 12 and the outer window frame panel 11 on the side facing the glass 3. The mounting part 13 has a sliding groove 131 opening towards the glass 3. A felt groove member 2 includes a felt groove body 22 connected to the sliding groove 131. The felt groove body 22 has a receiving groove 24 opening towards the glass 3. The felt groove body 22 also includes an inner lip 26 and an outer lip located at the opening position of the receiving groove 24. 25. The outer lip 25 includes a first connecting portion 252 and a second connecting portion 251 connected together. The first connecting portion 252 extends to the receiving groove 24, and the second connecting portion 251 extends to protrude and abut against the outer panel 11 of the window frame. The inner lip 26 includes a third connecting portion 262 and a fourth connecting portion 261 connected together. The third connecting portion 262 extends to the receiving groove 24. The first connecting portion 252 and the third connecting portion 262 are used to abut against the surface of the glass 3 that extends into the receiving groove 24. The fourth connecting portion 261 extends to protrude and abut against the inner panel 12 of the window frame.

[0040] In the above-described mating structure, the groove 2, in addition to mating with the slide groove 131, uses the inner lip 26 and outer lip 25 to position the first connecting portion 252 and the third connecting portion 262, located in the receiving groove 24, on both sides of the glass 3 in the thickness direction, allowing them to abut against the surface of the glass 3 using their own deformation capabilities. Furthermore, the C-pillar window frame has been redesigned. The mating structure of the inner window frame panel 12, the outer window frame panel 11, and the mounting portion 13 is relatively simple, meeting the requirements for vehicle lightweighting. The position and shape of the groove 2 on the inner window frame panel 12, the outer window frame panel 11, and the mounting portion 13 are relatively simple. The inner lip 26 and the outer lip 25 extend through the second connecting portion 251 and the fourth connecting portion 261 to abut against the corresponding outer window frame panel 11 and inner window frame panel 12, ensuring good installation stability and sealing. Therefore, the above-described mating structure provides good sealing performance, eliminates abnormal noise during glass 3 operation, and meets the requirements for vehicle lightweighting.

[0041] It is understandable that when no glass 3 is inserted, the first connecting part 252 and the second connecting part 251 abut against each other. When the glass 3 is raised and lowered into the receiving groove 24, the glass 3 can push the first connecting part 252 and the second connecting part 251 away from each other, so that the first connecting part 252 and the third connecting part 262 abut against the surface of the glass 3 respectively, so as to ensure a better sealing effect.

[0042] Optionally, the C-pillar window frame body 1 also includes a window frame reinforcement 14, which is fixedly connected to the side of the inner window frame panel 12 facing the outer window frame panel 11. The mounting part 13 is fixedly connected to the outer window frame panel 11 and the window frame reinforcement 14 at both ends in the thickness direction, respectively. This ensures that the C-pillar window frame body 1 has high strength while minimizing the increase in weight, meeting the lightweight requirements of the entire vehicle. The specific shape of the window frame reinforcement 14 and its specific mating shape with the inner window frame panel 12 and the outer window frame panel 11 can be adjusted according to requirements, and no specific limitation is made here. In this embodiment, the ends of the inner window frame panel 12 and the outer window frame panel 11 near the mounting part 13 are set as parallel flat plate structures, and the window frame reinforcement 14 is partially attached to the inner side of the inner window frame panel 12. This simplifies the structure of the inner window frame panel 12, the outer window frame panel 11, and the mounting part 13, reduces weight, and facilitates processing and forming.

[0043] Understandably, the outer window frame panel 11, the window frame reinforcement 14, the inner window frame panel 12, and the mounting part 13 are welded and fixed together. This further enhances the strength of the C-pillar window frame body 1 of the sheet metal parts.

[0044] In an optional embodiment, the mounting part 13 has a U-shaped plate structure in cross-section. The mounting part 13 has first limiting protrusions 132 protruding into the slide groove 131 on both sides along its thickness direction. The outer side of the groove body 22 has a protruding second limiting protrusion 23, which is an elastic member with deformability. The second limiting protrusion 23 abuts against the first limiting protrusion 132 to connect the groove member 2 to the slide groove 131. The two side walls of the U-shaped structure of the mounting part 13 are fixedly connected to the outer window frame panel 11 and the window frame reinforcement member 14, respectively, specifically by welding. In this embodiment, at least the outer window frame panel 11, the window frame reinforcement member 14, and the inner window frame panel 12, which are welded to the U-shaped side walls, have flat plate structures. The U-shaped side walls are in contact with the surfaces of the outer window frame panel 11 and the window frame reinforcement member 14; the specific mating structure is not described in detail here. First limiting protrusions 132 are provided on the U-shaped sidewall near the bottom wall of the slide groove 131. The main body 22 of the slide groove has an integrally formed second limiting protrusion 23. When connecting the main body 22 of the slide groove 22 to the mounting part 13, the main body 22 of the slide groove 131 is inserted into the slide groove. The second limiting protrusion 23 is slightly deformed by compression and moves along the U-shaped sidewall. The degree of compression deformation is greater at the position of the first limiting protrusion 132. After passing the first limiting protrusion 132, the second limiting protrusion 23 is slightly deformed and abuts against the first limiting protrusion 132 and the second limiting protrusion 23 along the depth direction of the slide groove 131, thereby preventing the main body 22 of the slide groove 22 from falling off. This type of fitting structure is simple, easy to assemble, and has high connection stability, preventing detachment.

[0045] like Figure 1 , Figures 5 to 7 As shown, along the extending direction of the groove 131, the groove component 2 includes a connected upper groove section 2a, a middle groove section 2b, and a lower groove section 2c. The surface of the second connecting portion 251 located in the upper groove section 2a, away from the groove body 22, is an arc-shaped surface 254. The surface of the second connecting portion 251 located in the lower groove section 2c, away from the groove body 22, is an inclined slope 255. The surface of the second connecting portion 251 located in the middle groove section 2b, away from the groove body 22, is a transition surface 253 that connects the arc-shaped surface 254 and the inclined surface 255. By setting the outward-facing side of the second connecting portion 251 in the upper groove section 2a as a rounded corner structure, the problem of frictional noise caused by the glass 3 contacting it during the rising process can be effectively avoided.

[0046] It is understandable that the middle section 2b of the groove is a corner position, and foam 21 is also provided at the corner position. Foam 21 is located between the inner bottom wall of the groove 131 and the outer bottom wall of the groove body 22, and is used to bond and fix the two to improve the reliability and stability of the connection and ensure better sealing performance.

[0047] Optionally, the cross-section of the groove body 22 is U-shaped. The groove body 22 includes a bottom wall 222 and a side wall 221. An outer lip 25 and an inner lip 26 are respectively connected to the two ends of the side wall 221. The second connecting portion 251 of the outer lip 25 extends to abut against the outer surface of the outer panel 11 of the window frame, and the fourth connecting portion 261 of the inner lip 26 extends to abut against the outer surface of the inner panel 12 of the window frame. Preferably, the fourth connecting portion 261 of the inner lip 26 at least covers the ends of the inner panel 12 of the window frame, the window frame mounting portion 13, and the window frame reinforcing member 14, effectively preventing wind noise generated during vehicle operation, ensuring better safety performance and connection stability, and improving assembly strength.

[0048] The main body 22 of the groove is a one-piece molded plastic or rubber part. Based on this, at least a portion of the sidewall 221 in the upper section 2a of the groove is made of metal fiber filaments 221a. Replacing a portion of the sidewall 221 of the groove body 22 with metal fiber filaments 221a prevents the upper section 2a of the groove from shrinking and deforming due to changes in the external environment (especially temperature), thus avoiding poor matching between the outer lip 25 and the outer panel 11 of the window frame, and consequently, problems such as gaps.

[0049] In an optional embodiment, in the felt member 2 located in the lower section 2c of the felt groove, along the extending direction of the second connecting portion 251, one end of the second connecting portion 251 abuts against the surface of the outer panel 11 of the window frame away from the inner panel 12 of the window frame, and the other end is provided with an abutting protrusion 256 protruding from the first connecting portion 252. The abutting protrusion 256 is used to abut against the glass 3. By providing the abutting protrusion 256, wind noise generated during vehicle operation can be effectively prevented.

[0050] Optionally, the felt part 2 in the upper section 2a and lower section 2c of the felt groove is at least partially prepared using a slip-material co-extrusion process to form a wear-resistant layer 2aa. This facilitates processing and, through slip-material co-extrusion, at least makes the surface that can contact the glass 3 more wear-resistant, avoiding the coating peeling caused by traditional coatings, and ensuring that the felt body 22 has good wear resistance.

[0051] Optionally, the mounting part 13 is provided with an opening 133 communicating with the slide 131, and the opening 133 is located at the position that mates with the middle section 2b of the trough. The mounting part 13 is formed by roll forming, and the outer window frame panel 11, the inner window frame panel 12, and the window frame reinforcement 14 are all integrally formed by stamping, which is simple in structure and low in cost. In addition, the opening 133 is provided in the mounting part 13 at the middle section 2b of the trough to prevent material accumulation and wrinkling deformation during the roll forming and bending process, thereby affecting the assembly of the trough body 22.

[0052] Optionally, the upper section 2a and lower section 2c of the trough body 22 are co-extruded and then injection molded together with the middle section 2b of the trough at the corner position.

[0053] Optionally, at least the groove section 2b of the groove is made of thermoplastic elastomer material with a textured surface and no coating. The back is fixed by foam 21, which can effectively prevent wind noise problems.

[0054] In addition, this application also provides a vehicle that includes the rear door C-pillar window frame assembly as described above, as detailed in the above embodiments, and will not be repeated here.

[0055] Understandably, vehicles can be any vehicle capable of movement, including those with autonomous or intelligent driving capabilities, such as passenger vehicles (cars, buses, coaches, minibuses, etc.), cargo vehicles (ordinary trucks, box trucks, trailer trucks, enclosed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, special structure trucks), special vehicles (logistics delivery vehicles, patrol cars, cranes, excavators, bulldozers, loaders, road rollers, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles), recreational vehicles (recreational vehicles, amusement park autonomous driving devices, balance scooters, etc.), and rescue vehicles (such as fire trucks, ambulances, power repair vehicles, engineering emergency vehicles, etc.).
