Description

Technical Field

[0001] This application relates to the field of automotive window frame accessories technology, and more particularly to a window structure, door assembly, and vehicle. Background Technology

[0002] As people's living standards improve, automobiles, as a basic means of transportation, are increasingly used in daily life. People also have higher expectations for the user experience, especially regarding unnecessary noise sources. In existing technology, the roof glass channel plays a crucial role in supporting, sealing, and cushioning the roof in car windows. However, the roof glass channel is also prone to poor sealing and noise during glass movement, resulting in a poor user experience.

[0003] Currently, during the glass lifting process, the glass typically stops moving when the top of the glass contacts the bottom wall of the glass groove, at which point the top of the glass is completely in contact with the bottom wall of the groove. When the glass descends, the top of the glass separates from the bottom of the groove. However, in this existing technology, when the glass lifts to contact the bottom of the groove, it directly impacts the entire groove, and since the bottom of the groove cannot be coated during production, a significant impact noise is generated. Furthermore, when the glass descends, the top of the glass separates from the bottom of the groove, producing a significant sticking noise, which negatively impacts the user's driving experience. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a window structure, a door assembly, and a vehicle, which optimizes the cross-sectional structure of the glass groove by setting buffer blocks in the first and second bends of the mounting groove and setting a bottom lip in the first connecting section. This allows the window glass to impact the buffer block instead of the initial impact on the inner bottom wall of the sealing lip during the lifting process, thereby reducing the impact area of ​​the window glass. This reduces the impact noise generated by the lifting of the window glass and the sticking noise generated by the descent. By setting the bottom lip, the sealing performance between the window glass and the sealing lip is improved, while the buffering force of the inner bottom wall of the sealing lip is increased, further reducing the sticking noise generated during the descent of the window glass.

[0006] To achieve the above objectives, in a first aspect, this application provides a vehicle window structure, comprising: A window frame, wherein a window frame opening is provided on the window frame frame; The vehicle window glass is slidably disposed on the window frame and is used to open or close the window frame opening; The mounting groove is formed on the inner sidewall of the window frame opening; Glass channel, wherein the glass channel is disposed in the window frame opening, the glass channel comprising: A sealing lip, at least partially disposed within the mounting groove, the sealing lip having an opening on the side facing the vehicle window glass, the sealing lip being used to seal the gap between the vehicle window glass and the mounting groove; A buffer block is disposed on the inner bottom wall of the sealing lip facing the side of the window glass.

[0007] In the technical solution, by setting up a buffer block, when the car window glass is raised, the top of the car window glass first comes into contact with the side of the buffer block facing the car window glass. Then the car window glass stops rising. At this time, the top of the car window glass is located in the sealing lip. While achieving a seal, the top of the car window glass impacts the buffer block, thereby reducing the impact area between the car window glass and the inner bottom wall of the sealing lip. This reduces the impact noise generated when the car window glass is raised, thus optimizing the car window structure and improving the user experience.

[0008] In some embodiments of this application, the mounting groove has two bent portions formed by bending; The first connecting section is located between the two bends of the mounting groove, and the first connecting section is located on the side of the mounting groove facing the top of the window glass. The buffer block is located at the bend.

[0009] In the technical solution, by setting buffer blocks in the first and second bends, the car window stops moving after hitting the buffer blocks when it is raised. At this time, the top of the car window is located between the first and second bends and does not make an impact, thereby reducing the contact area of ​​the car window hitting the top and thus reducing the impact sound of the car window rising.

[0010] In some embodiments of this application, the width direction of the buffer block is the same as the width direction of the mounting groove, the width of the buffer block is smaller than the width of the inner bottom wall of the sealing lip, and a deformation space is provided between the buffer block and the inner wall of the sealing lip.

[0011] In the technical solution, by limiting the width of the buffer block and the width of the inner bottom wall of the sealing lip, a deformation space is set. When the buffer block is impacted and undergoes elastic deformation, the buffer block extends to the deformation space on both sides. This improves the sealing performance of the first and second bends while preventing the buffer block from directly contacting the side wall of the sealing lip during installation. This would prevent the buffer block from deforming when impacted by the car window glass, thus avoiding assembly difficulties, poor sealing, and other problems that would affect the overall appearance of the car window structure.

[0012] In some embodiments of this application, the distance between the sealing lip and the opposite side walls gradually increases along the opening direction of the sealing lip.

[0013] In the technical solution, by limiting the specific shape of the sealing lip to increase the deformation space, when the impact force on the buffer block is large, the amount of deformation of the buffer block may not be sufficient when it is hit by the car window glass, which will cause the impact sound to exceed the original limit and cause a lot of noise when the user uses it.

[0014] In some embodiments of this application, the inner bottom wall of the sealing lip is provided with a bottom lip on the side facing the vehicle window glass. The bottom lip is located at the first connecting section and is used to seal the gap between the vehicle window glass and the first connecting section. An abutment portion is provided at the end of the bottom lip away from the sealing lip.

[0015] In the technical solution, by setting an abutment part, when the car window glass is raised, the abutment part moves towards the inner bottom wall of the sealing lip and abuts against the inner bottom wall of the sealing lip. While increasing the sealing between the top of the car window glass and the sealing lip, it further reduces the contact area between the car window glass and the inner bottom wall of the sealing lip. Due to the reduction in the contact area, the adhesion between the bottom lip and the inner bottom wall of the sealing lip is reduced.

[0016] In some embodiments of this application, the sealing lip is provided with an anti-sticking portion for abutting against the abutting portion on the side facing the window glass.

[0017] In the technical solution, by setting an anti-sticking part, when the car window glass hits the buffer block, the abutting part contacts the anti-sticking part instead of the inner bottom wall of the sealing lip. By changing the area of ​​the contact position between the abutting part and the inner bottom wall of the sealing lip, the sticking sound generated when the car window glass is lowered is further reduced.

[0018] In some embodiments of this application, the anti-stick portion includes a protrusion located on the side of the inner bottom wall of the sealing lip facing the opening direction of the sealing lip, and multiple protrusions are provided.

[0019] In the technical solution, by setting multiple continuous protrusions at the corresponding positions of the contact part, the bottom lip and the inner bottom wall of the sealing lip are transformed into linear contact, further reducing the original contact area, thereby further reducing the sticking sound generated when the car window glass is lowered.

[0020] In some embodiments of this application, the height direction of the buffer block is the same as the opening direction of the sealing lip, the height direction of the bottom lip is the same as the height direction of the buffer block, and the height of the buffer block is less than the height of the bottom lip.

[0021] In the technical solution, by limiting the relative height between the buffer block and the bottom lip, it is ensured that during the process of raising the window glass, the top of the window glass contacts the bottom lip first, and under the action of the window glass, the abutting part abuts against the anti-sticking part. Then the window glass impacts the buffer block to achieve a seal between the window glass and the glass groove. This reduces the sticking noise generated when the window glass is lowered and ensures the airtightness of the window glass.

[0022] Secondly, this application provides a vehicle door assembly, including the window structure as described above, the vehicle door assembly including a vehicle door sheet metal, and the window structure being integrally mounted on the vehicle door sheet metal.

[0023] In the technical solution, by setting the door sheet metal, the relative position of the window structure in the door assembly is limited, increasing the interaction between the occupants and the outside world, and improving the overall visual appeal of the door assembly.

[0024] Thirdly, this application provides a vehicle, including: The vehicle body is provided with a door assembly as described above.

[0025] In the technical solution, by setting the door assembly on the vehicle body, a light visual effect is created on the one hand, and the safety of the vehicle interior is increased on the other hand, providing protection for the safety of the vehicle's internal structure, such as door interiors, electronic components such as the dashboard, or the safety of the occupants.

[0026] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, as people's pursuit of user experience gradually increases, when purchasing a vehicle, users not only have requirements for vehicle performance, but also have higher requirements for their personal perception path and user experience in the vehicle during use.

[0031] In existing technology, the top glass groove located above the car window plays an important role in supporting, sealing, and cushioning the impact of the roof. However, when the car window rises to its top and abuts against the bottom of the glass groove, the entire top of the window impacts the bottom of the glass groove, and the sound is transmitted through the glass groove to the window frame sheet metal, resulting in a loud impact sound. When the car window is lowered, the lip of the glass groove is normally curved, making it impossible for the coating material to enter the glass groove. As a result, when the lip of the glass groove separates from the side wall of the car window during the descent, a sticking sound is generated. These noises interfere with the user experience, thereby lowering the user's overall evaluation of the vehicle.

[0032] Meanwhile, at the corners of the glass channel near the A-pillar, B-pillar, or B-pillar and C-pillar (i.e., the glass channel in the front door and the glass channel in the rear door), the lip of the glass channel at the top is difficult to connect with the lip at the corner, resulting in poor sealing at the corner and causing a lack of tightness, which further reduces the user's overall impression of the vehicle.

[0033] Based on this, this application provides a window structure, a door assembly, and a vehicle. By setting a buffer block at the bottom of the corner of the glass channel, the buffer block has a certain thickness and hardness, so that when the window glass is raised, the top of the window glass first impacts the buffer block, and then the window glass stops moving, instead of the top of the window glass completely sticking to the bottom of the glass channel before stopping. This reduces the contact area between the window glass and the glass channel, thereby reducing the impact noise when the window glass is raised. By setting a bottom lip, the bottom structure of the glass channel is optimized, so that after the window glass stops rising, the end of the bottom lip abuts against the bottom of the glass channel, thereby reducing the contact area between the bottom lip and the bottom of the glass channel, thus solving the problem of sticking noise when the window glass descends and detaches. At the same time, by connecting the buffer block and the bottom lip at the corner, the problem of poor sealing at the corner is solved.

[0034] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0035] As attached Figures 1 to 3 As shown in an illustrative embodiment of the window structure in this application, the window structure includes a window frame 100. The window frame 100 is generally located above the vehicle door frame, or it may be part of the door. Typically, the window frame 100 provides the user with a view, and it integrates with the vehicle body lines, providing a clean and smooth exterior profile. It also provides a certain degree of rigidity and strength support for the top of the door.

[0036] Understandably, the window frame 100 has a window frame opening for communication between the inside and outside of the vehicle, making it easier for passengers and the driver to observe the outside situation.

[0037] In some embodiments, the window structure includes a window glass 200, which is slidably disposed in the window frame 100. The window glass 200 provides a means for interaction between the vehicle interior and the outside world, while also providing safety protection for the vehicle interior. When encountering dangerous situations such as the vehicle sinking in water, the window glass 200 and the opening in the window frame where it is located can provide an escape route for the occupants of the vehicle.

[0038] Specifically, the window glass 200 slides against the window frame 100 and is used to close or open the window frame opening.

[0039] More specifically, the window glass 200 slides up and down to close the window frame opening.

[0040] In some embodiments, the window structure includes a mounting groove 300, which is formed in the window frame 100 and is used to provide a connection position for the installation of subsequent parts.

[0041] Specifically, the mounting groove 300 is located on the inner wall of the window frame opening.

[0042] In some embodiments, the window structure includes a glass groove disposed in the inner wall of the window frame opening. The glass groove is used to fill the gap between the window glass 200 and the window frame opening to increase the sealing between the two.

[0043] In some embodiments, the glass groove includes a sealing lip 400, which is disposed within the mounting groove 300. The sealing lip 400 is open on the side facing the window glass 200. The sealing lip 400 is used to seal the gap between the window glass 200 and the mounting groove 300 to increase the sealing between the window glass 200 and the mounting groove 300, thereby avoiding adverse consequences such as water leakage during car washes in rainy weather, corrosion inside the car door, and short circuits in the vehicle's electronic components.

[0044] In some embodiments, to further enhance the sealing between the glass groove and the window glass 200, the sealing lips 400 extend from both sides away from the bottom of the mounting groove 300 toward the middle of the inner bottom wall of the sealing lip 400, forming clamping lips 500 for interference contact with the window glass 200. By providing clamping lips 500, when the top of the window glass 200 rises to the sealing lip 400, both sides of the window glass 200 abut against the clamping lips 500, thereby sealing the gap between the window glass 200 and the two sides of the sealing lip 400, thus increasing the sealing between the window glass 200 and the window frame opening.

[0045] In some embodiments, the glass channel includes a buffer block 600, which is disposed on the inner bottom wall of the sealing lip 400 facing the side of the window glass 200. The window glass 200 stops moving when it rises to abut against the buffer block 600. The buffer block 600 is generally made of solid rubber, which has the characteristics of impact control and energy absorption. When impacted, the buffer block 600 can rebound instantaneously, converting mechanical energy into heat energy through vibration and dissipating it, thereby protecting the stability of the window glass 200 during a lift-off impact.

[0046] In the above technical solution, by setting a buffer block 600, when the window glass 200 is raised, the top of the window glass 200 first comes into contact with the side of the buffer block 600 facing the window glass 200, and then the window glass 200 stops rising. At this time, the top of the window glass 200 is located in the sealing lip 400. While achieving a seal, the top of the window glass 200 impacts the buffer block 600, thereby reducing the impact area between the window glass 200 and the inner bottom wall of the sealing lip 400, thus reducing the impact noise generated by the window glass 200 when it is raised, thereby optimizing the window structure and improving the user experience.

[0047] In some embodiments, refer to the appendix Figures 1 to 3In the basic structure of a common automobile, the core components of the car body frame include the A-pillar, B-pillar, C-pillar, and D-pillar. The front door is typically located between the A-pillar and B-pillar, while the rear door is typically located between the B-pillar and C-pillar. The bent portion of the mounting groove 300 is designated as a bent section, which includes a first bent section 301 and a second bent section 302, positioned opposite each other. Taking the front door as an example, the first bent section 301 is located near the top of the A-pillar, and the second bent section 302 is located near the top of the B-pillar. That is, when the window glass 200 is raised, the top end of the window glass 200 near the A-pillar and the top end near the B-pillar respectively abut against the first bent section 301 and the second bent section 302.

[0048] In some embodiments, a first connecting section 303 is provided between the first bending portion 301 and the second bending portion 302. The first connecting section 303 is located on the side of the mounting groove 300 facing the top of the window glass 200. That is, when the window glass 200 is raised, the top of the window glass 200 abuts against the first bending portion 301, the first connecting section 303 and the second bending portion 302, thereby realizing the connection between the window glass 200 and the mounting groove 300.

[0049] In some embodiments, refer to the appendix Figure 2 and attached Figure 3 Two buffer blocks 600 are provided, located in the first bend 301 and the second bend 302 respectively. Since the first bend 301 and the second bend 302 are located at opposite ends near the top of the window glass 200, by providing buffer blocks 600 in the first bend 301 and the second bend 302, when the window glass 200 is raised, it stops moving after hitting the buffer block 600. At this time, the top of the window glass 200 located between the first bend 301 and the second bend 302 does not generate the same impact intensity, thereby reducing the impact contact area of ​​the window glass 200 against the top and thus reducing the impact sound of the window glass 200 rising.

[0050] In some embodiments, refer to the appendix Figure 2 To be continued Figure 5To ensure the stability of the impact between the window glass 200 and the buffer block 600 during the lifting of the window, thereby reducing the impact noise, the width direction of the buffer block 600 is set to be the same as the width direction of the mounting groove 300. The width of the buffer block 600 is smaller than the width of the inner bottom wall of the sealing lip 400. The gap between the buffer block 600 and the inner wall of the sealing lip 400 is set as the deformation space 700. When the buffer block 600 is deformed by the impact of the window glass 200, due to the material characteristics of the buffer block 600, it has a certain degree of elasticity. The buffer block 600 extends to the deformation space 700 on both sides, which improves the sealing performance of the first bend 301 and the second bend 302, while preventing the buffer block 600 from directly contacting the side wall of the sealing lip 400 during installation. This would prevent it from deforming when impacted by the window glass 200, thus avoiding assembly difficulties, poor sealing, and other problems that would affect the overall appearance of the window structure.

[0051] In some embodiments, the width of the buffer block 600 is close to the width of the inner bottom wall of the sealing lip 400. If the width of the buffer block 600 is similar to the thickness of the window glass 200, when the window glass 200 rises and impacts the buffer block 600, the buffer block 600 has a certain probability of tilting, causing the top of the window glass 200 to impact the inner bottom wall of the sealing lip 400, which fails to achieve the desired effect. The improvement in impact sound is probabilistic. Therefore, setting the width of the buffer block 600 to be the same as the width of the inner bottom wall of the sealing lip 400 improves the user experience.

[0052] In some embodiments, refer to the appendix Figure 4 and attached Figure 5 To further increase the deformation space 700, the distance between the two side walls of the sealing lip 400 gradually increases along the opening direction of the sealing lip 400. Since the width of the buffer block 600 is similar to the width of the inner bottom wall of the sealing lip 400, when the impact force on the buffer block 600 is large, the buffer block 600 may not deform sufficiently when impacted by the car window glass 200, resulting in an impact sound exceeding the original limit and causing significant noise during user operation.

[0053] In some embodiments, refer to the appendix Figure 1 and attached Figure 6To reduce the sticking noise when the window glass 200 is lowered and detached, and to further ensure the sealing between the window glass 200 and the mounting groove 300, a bottom lip 800 is provided on the inner bottom wall of the sealing lip 400 facing the window glass 200. The bottom lip 800 is located in the first connecting section 303. One end of the bottom lip 800 near the inner bottom wall of the sealing lip 400 is located near the side wall of the sealing lip 400. The other end of the bottom lip 800 extends towards the opposite side wall of the sealing lip 400. An abutment part 801 is provided on the end of the bottom lip 800 away from the sealing lip 400, and the abutment part 801 faces the inner bottom wall of the sealing lip 400.

[0054] In the above technical solution, when the car window glass 200 rises and hits the buffer block 600, the top of the car window glass 200 and the bottom lip 800 abut against the side away from the inner bottom wall of the sealing lip 400. Under the force applied by the car window glass 200, the abutting part 801 moves towards the inner bottom wall of the sealing lip 400 and abuts against the inner bottom wall of the sealing lip 400. While increasing the sealing between the top of the car window glass 200 and the sealing lip 400, it further reduces the contact area between the car window glass 200 and the inner bottom wall of the sealing lip 400. When the car window glass 200 falls, the abutting part 801 moves away from the inner bottom wall of the sealing lip 400 under the action of elasticity. Due to the reduction of the contact area, the adhesion between the bottom lip 800 and the inner bottom wall of the sealing lip 400 is reduced.

[0055] In some embodiments, refer to the appendix Figure 6 and attached Figure 7 To further reduce the sticking noise generated when the window glass 200 descends, an anti-sticking part 802 is provided on the side of the sealing lip 400 facing the window glass 200 for contacting the abutment part 801. By providing the anti-sticking part 802, when the window glass 200 hits the buffer block 600, the abutment part 801 contacts the anti-sticking part 802 instead of the inner bottom wall of the sealing lip 400. By changing the contact area between the abutment part 801 and the inner bottom wall of the sealing lip 400, the sticking noise generated when the window glass 200 descends is further reduced.

[0056] In some embodiments, the anti-stick portion 802 includes a protrusion located on the side of the inner bottom wall of the sealing lip 400 facing the opening direction of the sealing lip 400, and multiple protrusions are continuously provided. When the window glass 200 stops rising, the top of the window abuts against the side of the bottom lip 800 away from the inner bottom wall of the sealing lip 400, and the abutting portion 801 abuts against the protrusion. Since multiple protrusions are continuously provided, the contact between the bottom lip 800 and the inner bottom wall of the sealing lip 400 becomes linear, further reducing the original contact area.

[0057] Analysis of commonly used materials for the bottom lip 800 and sealing lip 400 reveals an adhesive effect when they come into contact. A larger contact area results in stronger adhesion and a stronger noise pulse during separation. By incorporating protrusions, the continuous protrusions form multiple micro-fulcrums relative to the contact portion 801, altering the mechanical process of separation. The separation changes from a complete peeling of the contact portion 801 to a sequential detachment, significantly reducing energy release intensity. This resolves the sticking and rattling issue that occurs when the window glass 200 descends, improving the user experience when raising and lowering the window glass 200.

[0058] In some embodiments, the material used for the abutment portion 801 and the protrusion has a higher hardness than the material used for the bottom lip 800 and the sealing lip 400. By limiting the hardness of the material, the problem of abnormal noise caused by the adhesion effect is further reduced, thereby further improving the user experience.

[0059] In another embodiment, the abutment portion 801 and the raised surface are provided with a coating. By providing the coating, the adhesion between the bottom lip 800 and the inner bottom wall of the sealing lip 400 is further reduced, thereby reducing the sticking sound when the abutment portion 801 separates from the raised surface, and thus reducing the sticking sound generated when the bottom lip 800 separates from the sealing lip 400 when the window glass 200 is lowered.

[0060] In some embodiments, refer to the appendix Figure 4 To be continued Figure 6 Let the height direction of the buffer block 600 be the same as the opening direction of the sealing lip 400, and the height direction of the bottom lip 800 be the same as the height direction of the buffer block 600. In this direction, let the distance between the side of the bottom lip 800 away from the inner bottom wall of the sealing lip 400 and the side of the bottom lip 800 close to the inner bottom wall of the sealing lip 400 be the thickness of the bottom lip 800. Then the height of the buffer block 600 is greater than the thickness of the bottom lip 800. By limiting the height of the buffer block 600 and the thickness of the bottom lip 800, it is further ensured that after the window glass 200 is raised, the top of the window glass 200 stops after hitting the buffer block 600. Instead, after the window glass 200 deforms the buffer block 600, the top of the window glass 200 and the bottom lip 800 abut against the side away from the inner bottom wall of the sealing lip 400. This results in the bottom lip 800 fitting against the inner bottom wall of the sealing lip 400, but does not effectively reduce the contact area between the window glass 200 and the inner bottom wall of the sealing lip 400. Consequently, the impact sound generated by the raising of the window glass 200 and the sticking sound generated by its lowering are not significantly improved, thus violating the design expectations.

[0061] In some embodiments, to ensure the sealing of the first connecting section 303, when the top of the window glass 200 is not in contact with the glass groove, the height of the bottom lip 800 is greater than the height of the buffer block 600. This ensures that during the lifting process of the window glass 200, the top of the window glass 200 first contacts the bottom lip 800, and under the action of the window glass 200, the abutting part 801 abuts against the anti-sticking part 802. Then, the window glass 200 impacts the buffer block 600 to achieve a seal between the window glass 200 and the glass groove. This reduces the sticking noise generated when the window glass 200 descends while ensuring the sealing of the window glass 200.

[0062] In some embodiments, to further ensure that the design of the bottom lip 800 can effectively reduce the sticking noise generated when the window glass 200 is lowered, the material hardness of the buffer block 600 is greater than that of the bottom lip 800 and the sealing lip 400. In use, by limiting the relative hardness of the buffer block 600 and the bottom lip 800, it is further ensured that after the buffer block 600 is deformed by the impact of the window glass 200, a gap is left between the bottom lip 800 located in the middle of the inner bottom wall of the sealing lip 400 and the inner bottom wall of the sealing lip 400. This reduces the contact force between the abutment 801 and the protrusion, thereby reducing the sticking noise generated when the abutment 801 and the protrusion separate, while ensuring the sealing between the top of the window glass 200 and the sealing lip 400.

[0063] In some embodiments, in order to further improve the sealing performance while ensuring that the impact sound is reduced, the side of the buffer block 600 away from the first connecting section 303 extends infinitely towards both sides of the A-pillar and B-pillar respectively, depending on the processing capability, thereby increasing the sealing length and improving the sealing performance between the window glass 200 and the first bend 301 and the second bend 302.

[0064] In some embodiments, to further ensure sealing, the bottom lip 800 is fixedly connected to two buffer blocks 600 on the side near the first bend 301 and the side near the second bend 302, respectively. By setting the connection relationship between the bottom lip 800 and the buffer blocks 600, the sealing performance at the connection between the first bend 301 and the second bend 302 and the first connecting section 303 is improved, thereby further enhancing the sealing capability of the glass trough.

[0065] In some embodiments, to improve production assembly efficiency, the bottom lip 800, the buffer block 600, and the sealing lip 400 are integrally injection molded. The integral molding design reduces the time spent on multiple injection molding and assembly in segmented molding, shortens the production cycle, and avoids the accumulation of dimensional tolerances from multiple segment splicing, thus preventing the possibility of gaps and breakage at the joints after long-term use, and improving the overall stability and sealing performance of the product.

[0066] In addition, this application also provides a door assembly, which includes the aforementioned window structure and door sheet metal.

[0067] In some embodiments, refer to the appendix Figure 1 The window structure is integrally assembled onto the door sheet metal. The door sheet metal includes a lifting assembly for controlling the sliding of the window glass 200 within the window frame opening and a support beam 900 for enhancing the structural strength of the window. The support beam 900 is fixedly connected to the window frame 100. Taking the front door of a car as an example, the support beam 900 is located on the side closer to the A-pillar of the car, and the side of the support beam 900 closer to the first connecting section 303 is located in the first bending portion 301, in order to increase the structural strength of the window and enhance the outline of the window structure, thereby improving the aesthetics of the door assembly. Furthermore, this application also provides a vehicle comprising a body with the aforementioned door assembly mounted on it. The door assembly is located on the side of the body and is fixed between the A-pillar and B-pillar, and between the B-pillar and C-pillar. The window structure is typically located at the upper part of the door assembly. The placement of the window structure not only enhances the visual appeal of the door assembly, matching the contours of the body side, but also increases the driver's field of vision, providing a means for interaction between occupants and the outside world. By mounting the door assembly on the body, a lighter visual effect is created, while also increasing the safety of the vehicle's interior. This provides protection for the vehicle's internal structures, such as door trim, dashboard and other electronic components, as well as the safety of occupants, preventing external interference during vehicle operation and thus improving the overall user experience.
