Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a door corner window device, a method for forming a door corner window device, a door window assembly, and a vehicle. Background Technology

[0002] As the economy continues to grow and people's living standards improve, consumers are demanding higher and higher quality in the details of automobiles.

[0003] Automobiles are equipped with door and window assemblies. These assemblies typically consist of two parts: corner window units and sliding window units. When the corner window units and sliding window units are adjacent, they are usually mounted on the vehicle using a guide rail assembly. For example, the guide rail assembly includes a roughly I-shaped window guide rail with two U-shaped channels facing opposite directions. One U-shaped channel serves as a sliding guide channel for the sliding window, which is slidably accommodated within it. The other U-shaped channel is used to clamp the corner window. Obviously, this clamping method causes the outer surfaces of the U-shaped channels to protrude beyond the outer surfaces of both the corner window and the sliding window. This arrangement not only increases the vehicle's drag coefficient during driving, affecting fuel economy, but also generates wind noise, reducing the customer experience.

[0004] Therefore, it is necessary to design a door corner window device, a method for forming a door corner window device, a door and window assembly, and a vehicle to solve the problem of high wind resistance in the door and window assembly. Summary of the Invention

[0014] In one embodiment, the connecting column is constructed as a U-shaped groove structure with its opening facing a first side in a second direction. The U-shaped groove structure of the connecting column includes a groove bottom, and a first sidewall and a second sidewall opposite to the first sidewall are respectively provided on both sides of the groove bottom. The groove bottom, the first sidewall, and the second sidewall form the guide rail groove. The side of the first sidewall closest to the corner window glass is the connecting surface. The orthographic projection of the second sidewall along the second direction is greater than the orthographic projection of the first sidewall along the second direction, wherein the second direction is perpendicular to the first direction.

[0015] According to a second aspect of the present invention, a method for forming the above-described vehicle door corner window device is provided, comprising fixing the connecting post to the inner side of the corner window glass, wherein a sealing strip and a connecting strip are formed on the corner window glass by an injection molding process, the connecting strip being located between the connecting post and the corner window glass to fix the connecting post to the corner window glass.

[0016] According to a third aspect of the present invention, a vehicle door window assembly is provided, comprising:

[0026] The disclosure of this invention will become more readily understood by referring to the accompanying drawings. It should be understood that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this invention. In the drawings:

[0030] Figure 4 For from Figure 1 Enlarged view of point B;

[0031] Figure 5 A cross-sectional view of a vehicle door and window assembly according to an embodiment of the present invention is shown.

[0032] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0033] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0034] One embodiment of the present invention provides a corner window device for a vehicle door. For example... Figures 1 to 4 As shown, the corner window device includes a corner window glass 101 and a connecting pillar 102. The corner window glass 101 is installed on the vehicle door to ensure the passenger's visual openness. It should be noted that the corner window glass 101 in this application can be either a corner window glass located on the front side of the front door or a corner window glass located on the rear side of the vehicle. The connecting pillar 102 is located on the inner side of the corner window glass 101 (with the vehicle itself as a reference, the side closer to the passenger compartment is the inner side, and the side opposite to the inner side and farther from the passenger compartment is the outer side), and is itself a long pillar extending along the first direction of the corner window glass 101 (consistent with the vertical direction of the vehicle). A connecting surface 121 is formed on the connecting pillar 102, and the connecting pillar 102 is fixed to the inner surface of the corner window glass 101 through the connecting surface 121. In addition, a guide rail groove 122 extending along the first direction is provided on the connecting pillar 102 for mounting the movable glass 201. Specifically, a movable glass guide groove 203 is installed within the guide rail groove 122. Simultaneously, a guide strip 202 is fixed to the movable glass 201, with its free end inserted into the movable glass guide groove of the movable glass guide groove 203. A more detailed description of the structure follows. The guide rail groove 122 is located on the inner side of the corner window glass 101.

[0035] Therefore, in this application, the connecting post 102 is positioned on the inner side of the corner window glass 101, ensuring that it does not protrude from the outer side of the corner window glass 101. This helps to achieve a flush appearance between the corner window glass 101 and the vehicle's movable glass 201, avoiding excessive wind resistance and thus reducing wind noise. Simultaneously, the guide groove 122 provided on the connecting post 102 facilitates the installation of the movable glass 201, simplifies the structure, and reduces manufacturing costs. In particular, the guide groove 122's location on the inner side of the corner window glass 101 helps to achieve a flush appearance between the corner window glass 101 and the vehicle's movable glass 201.

[0036] In one embodiment, the connecting surface 121 is attached to the corner window glass 101 by means such as bonding. Of course, to simplify processing and ensure connection stability, the connecting post 102 can also be attached to the corner window glass 101 by injection molding. Specifically, the connecting surface 121 is attached to the corner window glass 101 via a connecting strip 104, which is an injection-molded rubber strip. By using the injection molding process, the connecting post 102 is fixed to the corner window glass 101 without the need for assembly structures such as bolts. This process is simple and easy to implement, and the connection strength can be ensured by adjusting the size of the connecting strip 104 to meet specific requirements. In particular, this method ensures that there is no gap between the connecting post 102 and the corner window glass 101, effectively preventing problems such as water leakage or poor airtightness.

[0037] Meanwhile, a sealing strip 105 is provided on the inner side of the corner window glass 101. Preferably, the sealing strip 105 is a rubber sealing strip. After connection, the sealing strip 105 abuts against the sheet metal of the door window frame for sealing. The sealing strip 105 and the connecting strip 104 are integral connecting parts and can be formed in the same injection molding process. This arrangement not only simplifies the entire manufacturing process of the door corner window device, simplifies the structure, and reduces production costs, but also improves the sealing effect.

[0038] According to this application, a connector 103 is provided at least one end of the connecting post 102 along its length. The connector 103 is used to fix the connecting post 102 to the vehicle door sheet metal, thereby fixing the corner window glass 101. It is evident that directly fixing the connector 103 to the connecting post 102 simplifies the connection process between the connecting post 102 and the door sheet metal, facilitating rapid assembly of the corner window glass and the door sheet metal.

[0039] Connectors 103 are provided at both ends of the connecting post 102 along its length. Specifically, the connector 103 includes a first connecting plate 131 located at the first end of the connecting post 102 (aligned with the upper end in the vertical direction of the vehicle) and a second connecting plate 132 located at the second end of the connecting post 102 (aligned with the lower end in the vertical direction of the vehicle). The first connecting plate 131 is plate-shaped and is used to fix it to the door / window frame sheet metal. To ensure a firm connection, the extension direction of the first connecting plate 131 is adapted to the door / window frame sheet metal so that it abuts against the door / window frame sheet metal face-to-face during the connection process. A first connecting hole 133 is provided on the first connecting plate 131 to allow, for example, a bolt to pass through, thereby ensuring that the first connecting plate 131 is fixed to the door / window frame sheet metal. To increase the strength of the first connecting plate 131 and ensure the stability of the connection, a reinforcing rib plate 134 is provided between the first connecting plate 131 and the connecting post 102. The second connecting plate 132 is provided with a second connecting hole 135, which is used for, for example, bolts to pass through, thereby ensuring that the second connecting plate 132 is connected to the sheet metal of the door window frame. Preferably, the first connecting plate 131 and the second connecting plate 132 are respectively provided on both sides of the connecting post 102 in a second direction (consistent with the front-rear direction of the vehicle). For example, the first connecting plate 131 is located on the front side of the connecting post 102, and the second connecting plate 132 is located on the rear side of the connecting post 102. This arrangement can effectively ensure the fixed stability of the connecting post 102.

[0040] Preferably, the connector 103 and the connecting post 102 are integrally connected. Furthermore, the connector 103 and the connecting post 102 are integrally molded using an injection molding process. This arrangement reduces the number of parts and assembly layers, improving assembly convenience. Additionally, this arrangement reduces the mating clearance, improves sealing performance, prevents water from entering the vehicle interior through assembly gaps, and also reduces the need for additional sealing materials.

[0041] This application also relates to a method for forming a corner window assembly for a vehicle door. In the manufacturing process, firstly, a connecting post 102 and a corner window glass 101 are prepared. Then, an injection molding operation is performed to fix the connecting post 102 to the inner side of the corner window glass 101. Specifically, a sealing strip 105 and a connecting strip 104 are formed on the corner window glass 101 through an injection molding process. The connecting strip 104 is located precisely between the connecting post 102 and the corner window glass 101 to achieve a connection and fixation between the two. The formed sealing strip 105 is used to abut against the door sheet metal after the corner window glass assembly is installed on the vehicle door, forming a seal. It can be seen that the sealing strip 105 and the connecting strip 104 are made of the same material. This manufacturing method uses a mature injection molding process, resulting in relatively low production costs. In particular, this manufacturing method can form the sealing strip 105 and the connecting strip 104 on the corner window glass 101 in a single process, effectively simplifying the overall manufacturing process. Furthermore, this method can integrate the connecting post 102 and the corner window glass 101 into a whole. During the installation process, the corner window glass 101 can be installed simply by fixing the connecting post 102 to the door sheet metal. This reduces the number of assembly levels, shortens the dimensional chain, and improves dimensional accuracy, resulting in better matching of the gaps and surface differences between the corner window and the surrounding mating parts.

[0042] This application also relates to door and window assemblies. For example... Figure 5 As shown, the door and window assembly includes the aforementioned door corner window device, movable glass 201, guide strip 202, and movable glass guide channel 203. The movable glass 201 is positioned on the first side of the corner window 101 in the second direction (depending on the needs of different doors, the corner window 101 can be positioned either in front of or behind the movable glass 201; for example, typically, for the front door of a vehicle, the movable glass 201 is positioned behind the corner window 101, while for the rear door, it is positioned in front). The movable glass 201 and the corner window 101 are spaced apart in the second direction to ensure that the movement of the movable glass 201 is not interfered with. In the closed state, the outer surface of the movable glass 201 is flush with the outer surface of the corner window 101 to ensure a smooth appearance and improve aesthetics. The movable glass 201 can move vertically relative to the vehicle to adjust the amount of air entering the passenger compartment. The movable glass guide groove 203 is embedded in the guide rail groove 122, and its main function is sealing. The guide strip 202 is fixedly set on the second side of the movable glass 201 in the second direction (opposite to the first side direction). The guide strip 202 is inserted into the movable glass guide groove 231 of the movable glass guide groove 203. During the assembly of the movable glass 201, the guide strip 202 guides the movable glass 201 through the cooperation between it and the movable glass guide groove 203.

[0043] In one embodiment, the connecting post 102 is constructed as a U-shaped groove structure with its opening facing a first side in a second direction. Specifically, the connecting post 102 includes a groove bottom 1021. A first sidewall 1022 and a second sidewall 1023 are respectively provided on both sides of the groove bottom 1021, with the first sidewall 1022 and the second sidewall 1023 distributed at intervals. The groove bottom 1021, the first sidewall 1022, and the second sidewall 1023 together form a guide groove 122. The outer surface of the groove wall of the U-shaped groove structure of the connecting post 102, near the corner window glass 101, i.e., the side of the first sidewall 1022 near the corner window glass 101, forms a connecting surface 121. This configuration of the connecting post 102 allows for easy adjustment of the dimensions of the connecting surface 121 in the second direction, ensuring stable connection with the corner window glass 101. The structure is simple and effectively meets the installation requirements of the corner window glass 101. Compared to existing structures, the connection between the connecting post 102 and the corner window glass 101 has a smaller dimension in the second direction, which can effectively reduce the width of the black area (the opaque area on the corner window glass 101) and increase the light transmission area of ​​the corner window glass 101, providing users with a better viewing experience. In addition, the orthographic projection of the second sidewall 1023 along the second direction is larger than the orthographic projection of the first sidewall 1022 along the second direction, allowing the second sidewall 1023 to extend outwards from the corner window glass 101 in the second direction. This arrangement facilitates the installation of the movable glass 201.

[0044] The movable glass guide channel 203 is constructed as a U-shaped groove structure that matches the connecting post 102. After installation, the movable glass guide channel 203 is at least partially inserted into the guide rail groove 122. To ensure that the movable glass guide channel 203 is stably installed on the connecting post 102, a first engaging tooth 123 is provided on at least one of the corresponding surfaces of the first side wall 1022 and the second side wall 1023 of the connecting post 102. Simultaneously, second engaging teeth 232 are provided on both sides of the groove wall of the U-shaped groove structure of the movable glass guide channel 203 to engage with the first engaging tooth 123. After installation, the first engaging tooth 123 and the second engaging tooth 232 engage to prevent the movable glass guide channel 203 from dislodging from the guide rail groove 122. It can be understood that the first engaging tooth 123 is provided on both the first side wall 1022 and the second side wall 1023 of the connecting post 102 to effectively limit the position of the movable glass guide channel 203.

[0045] Additionally, a sealing groove 233 is provided on the side wall of the movable glass guide 203 away from the corner window glass 101. The free end of the side wall of the connecting post 102 away from the corner window glass 101 is inserted into the sealing groove 233. The opening of the sealing groove 233 is elastically deformed to support the groove wall of the connecting post 102. To facilitate the insertion of the connecting post 102 into the sealing groove 233, the free end of the side wall of the connecting post 102 away from the corner window glass 101 can be thinned.

[0046] Multiple (e.g., two) steps 237 are constructed on the side of the movable glass guide channel 203 near the corner window glass 101 to adapt to the side wall of the connecting post 102 and the corner window glass 101, thereby improving the sealing effect. Additionally, a first sealing lip 234 is provided at the free end of the side wall of the movable glass guide channel 203 near the corner window glass 101. The first sealing lip 234 extends between the movable glass 201 and the corner window glass 101, and is located inside the outer surface of the corner window glass 101; that is, the first sealing lip 234 does not protrude from the outer surfaces of the corner window glass 101 and the movable glass 201. The first sealing lip 234 seals the gap between the movable glass 201 and the corner window glass 101, ensuring a tight seal. Furthermore, the shape of the first sealing lip 234 is relatively easy to adjust, thereby ensuring a smooth transition from the movable glass 201 to the corner window glass 101.

[0047] Additionally, a second sealing lip 235 and a third sealing lip 236 extending toward the movable glass 201 are provided on the side of the movable glass guide channel 203 away from the corner window glass 101. The second sealing lip 235 seals against the movable glass 201. The third sealing lip 236 seals against the guide strip 202. The first sealing lip 234, the second sealing lip 235, and the third sealing lip 236 are all constructed such that... Figure 5 The cross-section is strip-shaped to ensure a sliding seal. When it is necessary to adjust the airflow into the passenger compartment, the movable glass 201 moves along the vertical direction of the vehicle, thereby moving the guide strip 202. The first sealing lip 234, the second sealing lip 235, and the third sealing lip 236 described above can effectively ensure the seal around the movable glass 201. Therefore, the door and window assembly of this application not only ensures a smooth appearance and meets styling requirements, but also improves the convenience of door assembly and sealing performance while fulfilling the lifting function.

[0048] This application also relates to vehicles, including the aforementioned door and window assemblies.
