These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] With the upgrading of consumption, the increasing maturity of frameless door systems, and the reduction in costs, frameless doors are being used more and more in automobiles, especially in new energy vehicles, and have seen explosive growth in recent years. In order to reduce the A-pillar obstruction angle, the window assemblies of frameless doors are increasingly adopting corner window structures in the front triangular area of ​​the door.

[0048] In related technologies, the corner window glass and the door glass are positioned by a corner window guide groove, wherein the door glass is slidably connected to the corner window guide groove.

[0049] The gap between the door glass and the corner window guide channel can easily become a flow path for liquid, resulting in poor overall sealing of the window assembly.

[0050] This disclosure provides a frameless vehicle door window assembly, referring to... Figure 1 and Figure 2 As shown, the window assembly includes a corner window guide rail 1, a corner window glass 2, a corner window guide channel 3, and a door glass 4. The corner window guide rail 1 is used to connect to the door body and provide fixation and support for the corner window guide channel 3. The corner window glass 2 is connected to both the corner window guide rail 1 and the corner window guide channel 3.

[0051] The corner window guide channel 3 engages with the corner window guide rail 1 and is slidably connected to the door glass 4. In this way, the door glass 4 can slide relative to the corner window guide channel 3, thereby achieving the goal of raising and lowering the door glass 4 according to different needs of passengers. The end of the corner window guide channel 3 away from the door body has a protrusion 3a, which covers the gap between the corner window guide channel 3 and the door glass 4.

[0052] In this way, the protrusion 3a can cover the gap between the corner window guide groove 3 and the door glass 4, preventing the gap from being directly exposed to the external environment, effectively blocking the potential flow path of external liquid foreign objects (such as rainwater, car wash water, etc.), thereby reducing the possibility of external liquid foreign objects entering the interior of the window assembly along the gap and improving the overall sealing performance of the window assembly.

[0053] In some embodiments, refer to Figure 3 As shown, the protrusion 3a has a brim structure, that is, an outwardly extending curved surface. The brim structure can cover not only the top of the door glass 4 (i.e., Figure 3 The top of the X-axis can also cover the two side walls of the door glass 4 (i.e. Figure 3 The two side walls along the Y-axis (the side wall facing the outside of the vehicle and the side wall facing the passenger compartment) effectively block external liquid objects from a wider range of angles, such as rainwater tilted by the wind.

[0054] At the same time, the brim structure can also beautify the appearance, making the assembled corner window guide groove 3 and door glass 4 more flat, refined and beautiful, thereby improving the vehicle's market competitiveness.

[0055] In some embodiments, the corner window guide rail 1 and the corner window glass 2 are bonded together by structural adhesive 5. On the one hand, by using structural adhesive 5, stress can be evenly distributed across the entire bonding surface between the corner window guide rail 1 and the corner window glass 2, avoiding the stress concentration problems caused by traditional spot welding, riveting, bolt fixing, etc., thereby enabling more even force transmission and improving the reliability and durability of the connection.

[0056] On the other hand, the corner window guide rail 1 and the corner window glass 2 are made of different materials. The structural adhesive 5 has excellent bonding performance and can effectively bond materials of different materials, such as metal, plastic and glass. This gives the structural adhesive 5 a significant advantage when connecting dissimilar materials, which can improve the overall performance and reduce problems such as inconsistent thermal expansion coefficients caused by material differences.

[0057] On the other hand, structural adhesive 5 can effectively fill the gap between the corner window guide rail 1 and the corner window glass 2, achieving a good sealing effect, thereby ensuring that the window assembly has good sealing performance.

[0058] In some embodiments, refer to Figure 10 As shown, the corner window guide channel 3 and the corner window glass 2 are bonded together with sealant 6. The sealant 6 effectively fills the gap between the corner window guide channel 3 and the corner window glass 2, reducing the possibility of liquids or foreign objects passing through. Furthermore, it improves the sound insulation level of the window assembly, reducing wind noise impact on passengers inside the passenger compartment.

[0059] In some embodiments, the corner window glass 2 and the door glass 4 are both double-pane glass (also known as laminated glass), which consists of two layers of glass sandwiched with a dry air layer or a special material (such as a PVB interlayer film).

[0060] The air layer or special materials in double-glazed windows provide excellent heat insulation, reducing heat exchange between the inside and outside of the vehicle. This helps reduce the frequency of air conditioning use, thereby lowering the vehicle's energy consumption. The cavity design of double-glazed windows also hinders sound transmission, resulting in better sound insulation and significantly improving the comfort of the driver and passengers during driving.

[0061] At the same time, when double-glazed windows break under external force, most of the glass fragments will remain in the space between the two panes of glass, unlike single-glazed windows which scatter over a large area. This avoids danger to pedestrians and other vehicles and improves driving safety.

[0062] In some embodiments, the corner window guide rail 1 is made of a material with high hardness, so that the corner window guide rail 1 can effectively fix and support the corner window guide groove 3. At the same time, it also makes the connection strength between the corner window guide rail 1 and the door body high, and the risk of the two breaking or falling off during vehicle use is small.

[0063] The material of the corner window guide rail 1 can be matched and set according to parameters such as the vehicle's usage environment, the performance requirements of the corner window guide rail 1, and the manufacturing cost. For example, aluminum alloy, copper, plastic (such as polyvinyl chloride, PVC), composite materials, etc.

[0064] In some embodiments, the corner window guide channel 3 is made of a material with low hardness. In this way, after being pressed against the corner window glass 2 or the door glass 4, the corner window guide channel 3 can undergo a certain deformation and fit tightly against the corner window glass 2 or the door glass 4, thus avoiding excessive gaps between components.

[0065] The material of the corner window guide channel 3 can be matched and set according to parameters such as the vehicle's usage environment, the performance requirements of the corner window guide channel 3, and the manufacturing cost. For example, it can be ethylene propylene diene monomer (EPDM) or thermoplastic elastomer (TPE).

[0066] In some embodiments, refer to Figure 5 As shown, on the side facing the vehicle interior, the corner window guide groove 3 and the corner window guide rail 1 are matched with zero step difference, that is, there is no height difference between the side wall of the corner window guide groove 3 facing the vehicle interior and the side wall of the corner window guide rail 1 facing the vehicle interior, and they are in a flush state.

[0067] In this way, on the one hand, from the perspective of the passenger cabin, the two flush components reduce visual clutter and make the overall design look simpler and more elegant; on the other hand, it reduces the risk of the protruding components being damaged when they are not flush.

[0068] In some embodiments, refer to Figure 7 As shown, the end 1a of the corner window guide rail 1, away from the door body, is treated to remove sharp angles. Firstly, since the corner window guide rail 1 is made of a material with higher hardness, and the corner window guide groove 3 is made of a material with lower hardness, the removal of sharp angles can prevent the presence of sharp angles from causing personal injury to personnel (e.g., users, assembly personnel, after-sales maintenance personnel, etc.) or scratching or abrasion to other objects passing by (e.g., clothing, mobile phones, etc.). Secondly, by adjusting the flatness and dimensional parameters of the edge of end 1a, the aesthetics of the corner window guide rail 1 are improved.

[0069] In some embodiments, refer to Figure 6 As shown, when the door glass 4 is in the raised state, the door glass 4 and the protrusion 3a are in an interference fit. Here, the interference fit refers to the interference fit in the height direction of the vehicle.

[0070] The protrusion 3a is typically made of EPDM rubber or thermoplastic elastomer, thus possessing a certain degree of elasticity. When the door glass 4 and the protrusion 3a are in an interference fit, the mating surface of the protrusion 3a can undergo slight deformation under pressure from the door glass 4, thereby filling the tiny gap between the door glass 4 and the protrusion 3a and further improving the sealing effect of the protrusion 3a.

[0071] In some embodiments, refer to Figure 8 As shown, the end of the corner window guide groove 3 furthest from the door body has an L-shaped structure (i.e., Figure 8 The structure corresponding to the dashed frame in the middle, the two sections of the L-shaped structure are respectively attached to the side wall in the thickness direction of the corner window glass 2 and the side wall facing the interior of the vehicle.

[0072] Compared to a straight-line structure, an L-shaped structure extends the flow path of external liquids and increases the tortuosity of the flow path. This extended and more complex flow path means less time for water film to accumulate on the window assembly, thus reducing liquid accumulation. Simultaneously, extending the flow path of liquids on the window assembly more effectively reduces the likelihood of rainwater and other liquids entering the vehicle through the window assembly, thereby enhancing the vehicle's waterproof and sealing performance.

[0073] In some embodiments, refer to Figure 5 As shown, the corner window guide rail 1 and the corner window guide groove 3 have a first locking gap A away from the corner window glass 2 and a second locking gap B close to the corner window glass 2. In the vehicle height direction, the first locking gap A is higher than the second locking gap B.

[0074] The corner window guide rail 1, corner window glass 2, and corner window guide channel 3 form a partial sandwich structure. Since the corner window guide rail 1 and corner window glass 2 are two independent components, there may be a certain gap between them. Figure 5 As indicated by the arrow, liquid foreign objects can flow into the interior of the window assembly from the gap between the two, and then flow through the second snap-fit ​​gap B. At this time, since the first snap-fit ​​gap A is higher than the second snap-fit ​​gap B in the vehicle height direction, the liquid foreign objects gradually flow to the outside of the vehicle along the preset drainage pipe pointing to the ground under the action of gravity, and will not pass through the first snap-fit ​​gap A to enter the passenger compartment.

[0075] Therefore, the setting of the first interlocking gap A being higher than the second interlocking gap B can effectively block the flow of liquid foreign matter into the passenger compartment, ensuring that the passenger compartment is not affected by the external environment and will not experience adverse phenomena such as water ingress or dampness.

[0076] In some embodiments, refer to Figure 4 At the CC position of the window assembly, the corner guide groove 3 has an L-shaped bubble tube in the corner area (i.e., Figure 4 (the structure corresponding to the dashed frame), thus effectively fitting the door glass 4; refer to Figure 10 As shown, at the DD position of the window assembly, the small bubble tube in the corner area of ​​the corner window guide groove 3 has a V-shaped structure (i.e., Figure 10 (The structure corresponding to the dashed frame in the middle) In this way, when the corner window guide channel 3 abuts against the door glass 4, the corner window guide channel 3 deforms but does not produce material overlap or serious deformation, while taking into account both the sealing between the corner window guide channel 3 and the door glass 4 and the aesthetics of the door glass 4.

[0077] Therefore, from the side closest to the door body to the side furthest from the door body, the cross-sectional shape of the small bubble tube in the corner area of ​​the corner window guide groove 3 gradually transitions from an L-shaped structure to a V-shaped structure. This is to prevent a multi-layered material structure from forming in some areas of the corner window guide groove 3 when it comes into contact with the door glass 4. Consequently, in the direction perpendicular to the door glass 4, the different thicknesses in different areas of the corner window guide groove 3 result in a larger gap between the corner window guide groove 3 and the door glass 4, thus ensuring the sealing performance between the corner window guide groove 3 and the door glass 4.

[0078] Secondly, this disclosure also provides a door assembly, which may include a window assembly and a door body as described in any of the embodiments of the first aspect, with the corner window guide rail 1 connected to the door body.

[0079] The corner window glass 2 is connected to the corner window guide rail 1, and the corner window guide groove 3 is engaged with the corner window guide rail 1. Therefore, the door body can drive the window assembly to open or close, thereby achieving the goal of making the door assembly a frameless door.

[0080] This disclosure does not specify the connection method between the corner window guide rail 1 and the door body. It can adopt detachable connection methods such as threaded fastening, snap-fit ​​connection, and slot connection, or non-detachable connection methods such as glue application, welding, and bonding connection. The specific method can be matched and set according to factors such as the vehicle's usage scenario and the connection strength requirements between the corner window guide rail 1 and the door body.

[0081] Thirdly, this disclosure also provides a vehicle, which includes a door assembly and a side panel assembly 100 as described in the second aspect embodiment, referring to... Figure 9 As shown, the side panel assembly 100 includes a side panel body, a side panel bright strip 101, a door frame sealing strip 102, and a side panel sealing strip 103.

[0082] Side panel trim 101 enhances the vehicle's lines and definition, making it look more stylish and upscale. Typically featuring a metallic or matte finish, it contrasts sharply with the body color, highlighting the vehicle's contours and lines. Side panel trim 101 also provides some protection for the vehicle body. For example, during driving, it acts as an extra layer of protection, reducing impacts and scratches from stones and debris. Furthermore, its installation reduces direct contact between the vehicle and the external environment, thus slowing down aging and corrosion.

[0083] Both the side bright strip 101 and the door frame sealing strip 102 are connected to the side body. The side bright strip 101 has a mounting groove 101a. The side sealing strip 103 is located in the mounting groove 101a and is connected to the side bright strip 101. When the door assembly is closed, the corner window glass 2 abuts against the door frame sealing strip 102 and the side sealing strip 103 respectively.

[0084] The corner window glass 2 abuts against the door frame sealing strip 102 and the side sealing strip 103 to form a tight sealing structure, ensuring that when the door assembly is closed and the door glass 4 is raised, liquid foreign objects cannot enter the interior of the passenger compartment from the gap between the door assembly and the side assembly 100.

[0085] Meanwhile, when the door assembly is closed and the door glass 4 is raised, the end of the corner window guide groove 3 away from the door body and the protrusion 3a can be hidden inside the side sealing strip 103, thereby improving the aesthetics of the door assembly and the side assembly 100.

[0086] In some embodiments, the side sealing strip 103 has a cavity, and the side assembly 100 further includes a filler 104 located in the cavity. The filler 104 can increase the local sealing ballast and improve the sealing performance of the side sealing strip 103.
