Description

Technical Field

[0001] This utility model relates to the technical field of vehicle corner windows, and in particular to an upper positioning structure for a corner window and a vehicle including the upper positioning structure for the corner window. Background Technology

[0002] The corner window of a car door is a standard feature on vehicles. It typically has a mounting and positioning mechanism; currently, traditional corner windows on the market are mounted using an L-shaped sheet metal bracket and a sheet metal positioning system. For example... Figure 1 The image shows a common L-shaped sheet metal bracket. The L-shaped sheet metal bracket is first bent into an "L" shape, and then formed through a flanging, punching, and tapping process. Figure 1 Area A is the bending area, and area B is the punching and tapping area. Then, the L-shaped sheet metal bracket is spot welded to the sheet metal guide rail.

[0003] Traditional car door corner window components such as Figure 2 As shown, it includes an L-shaped bracket 1, a metal guide rail 2, TPV coating 4, and glass 3. The L-shaped bracket 1, metal guide rail 2, and metal bracket of a traditional corner window are connected by spot welding. Welding fixtures and inspection tools are required to achieve welding and product inspection. The welded finished product is then injected with glue in an injection mold to complete the corner window production.

[0004] Due to limitations in the stamping, bending, and welding precision of the L-shaped bracket, the product consistency of the car door corner window is poor. At the same time, it is easily deformed under high pressure in the injection mold, which can easily damage the mold. During the installation of the finished product, problems such as corner window deformation, installation difficulties, and poor matching effect are likely to occur. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art where the L-shaped sheet metal bracket of the car door corner window is easily deformed under high pressure in the injection mold, which easily damages the mold, and the finished product is prone to corner window deformation, installation difficulty, and poor matching effect during installation.

[0006] To address the aforementioned technical problems, this utility model discloses an upper positioning structure for a corner window. The corner window includes corner window glass and a flexible covering member disposed around the edge of the corner window glass. The upper positioning structure includes a guide rail extending along the height direction of the corner window glass and a positioning component extending along the width direction of the corner window glass. The guide rail is erected on the upper side of the corner window glass, and the positioning component is disposed at the upper edge of the corner window glass.

[0007] The positioning component includes an integrally formed component body and an insert mounting portion. The insert mounting portion is located on the upper part of the component body, near the guide rail. The component body extends along its width, and its bottom wall at least partially abuts against the top edge of the corner window glass. The insert mounting portion is provided with an insert mounting groove, and an anti-rotation positioning insert is detachably installed in the insert mounting groove. The axial direction of the anti-rotation positioning insert is parallel to the height direction. Furthermore, the flexible covering at least covers the side edge of the corner window glass, the guide rail, and the component body, and the top of the insert mounting portion protrudes from the flexible covering as a mounting end face.

[0008] By adopting the above technical solution, this utility model provides an upper positioning structure for a corner window. The traditional L-shaped sheet metal bracket is replaced by a positioning component and an anti-rotation positioning insert. The corner window product is then completed by injection molding a flexible covering. The positioning component includes the component body. During injection molding, it is not affected by the accuracy of the guide rail or the deformation of the injection molding. It has the advantages of small dimensional fluctuation, high stability, and small deformation during injection molding.

[0009] The bottom wall of the positioning component abuts against the top edge of the corner window glass, and the positioning component and the corner window glass support and abut against each other. This structure can better disperse and resist external forces, thereby improving the overall strength of the corner window structure. Furthermore, the component body is not L-shaped, resulting in small deformation and high stability during installation, injection molding, or other processes. It is easy to install and position, and the component body of this structure is also simpler to manufacture, with a simpler structure. Therefore, the manufacturing process, structural strength, installation efficiency, and matching efficiency of the positioning component in the upper positioning structure of the corner window disclosed in this application are greatly improved compared to the L-shaped stamped sheet metal bracket.

[0010] The present invention also discloses an upper positioning structure for a corner window, wherein the lower part of the component body and the edge along the width direction are provided with an extension extending toward the corner window glass, and the inner wall of the extension at least partially abuts against the corresponding side of the top of the corner window glass.

[0011] More preferably, the inner wall of the extension is provided with a plurality of abutment protrusions facing the corner window glass at intervals.

[0012] By adopting the above technical solution, the extension provided at the lower part of the component body can increase the contact area between the extension and the corner window glass, which can enhance the stability of the structure and reduce the shaking and deformation of the corner window glass. Furthermore, the abutment protrusions provided at intervals on the inner wall of the extension can make the force on the corner window glass more uniform and create a gap between the extension and the corner window glass. Therefore, when the flexible covering is injection molded, the injection molten material will flow into the gap, making the connection between the corner window glass and the extension more compact and the stability higher.

[0013] More preferably, the top of the insert mounting portion protrudes from the flexible covering as a mounting end face, wherein, in the thickness direction of the corner window glass, the thickness of the component body and the insert mounting portion is greater than the thickness of the extension portion. Furthermore, the bottom wall of the component body and the insert mounting portion adapts to the top edge of the corner window glass, and when viewed along the thickness direction of the corner window glass, the bottom wall presents a smooth transition surface that adapts to the top edge of the corner window glass.

[0014] More preferably, the extension is further provided with material flow holes, which include a plurality of material flow holes spaced apart from each other in the width direction. Among the plurality of material flow holes, a portion of the material flow holes extend through the extension in the width direction, and another portion of the material flow holes extend through the extension in the height direction.

[0015] More preferably, the insert mounting portion is provided with an insert mounting groove, and an anti-rotation positioning insert is detachably disposed within the insert mounting groove. The axial direction of the anti-rotation positioning insert is parallel to the height direction. The insert mounting groove is a mounting hole extending downward from the top, and multiple serrated protrusions are evenly arranged circumferentially on the inner peripheral wall of the mounting hole. The anti-rotation positioning insert includes an insert nut that can be fitted into the mounting hole, and a fixing hole is provided in the center of the insert nut.

[0016] The insert nut includes a first star-shaped anti-rotation shaft section, a middle shaft section, and a second star-shaped anti-rotation shaft section integrally formed along the axial direction. The outer periphery of the first star-shaped anti-rotation shaft section and the second star-shaped anti-rotation shaft section are provided with multiple serrated grooves that are adapted to multiple serrated protrusions, and the diameter of the first star-shaped anti-rotation shaft section and the second star-shaped anti-rotation shaft section is larger than the diameter of the middle shaft section.

[0017] More preferably, the flexible overlay is formed by injection molding around the edge of the corner window glass using any one of the following materials: TPV adhesive, polyurethane adhesive, butyl adhesive, and silicone.

[0018] The present invention also discloses an upper positioning structure for a corner window. When a flexible covering is formed by injection molding, the positioning component, the corner window glass, and the guide rail are placed in the injection mold, and the anti-rotation positioning insert is installed in the insert mounting groove. The bottom wall of the positioning component is attached to the top edge of the corner window glass, and the guide rail is erected on the upper side of the corner window glass. Furthermore, the injection molding material enters the injection mold and forms a flexible covering.

[0019] Using the above technical solution, the flexible covering is formed on the periphery of the positioning component, corner window glass and guide rail by injection molding. It has the advantages of simple process, simple and convenient molding process and the whole component is integrated after molding.

[0020] This utility model also discloses an upper positioning structure for a corner window. The extension of the positioning component is provided with multiple positioning grooves, and the inner wall of the injection mold is provided with multiple positioning protrusions that fit the positioning grooves. The multiple positioning grooves include at least one main positioning groove and at least one auxiliary positioning groove spaced apart along the width direction. Each main positioning groove is a circular hole penetrating the extension, and each auxiliary positioning groove is an oblong hole penetrating the extension and extending along the length direction of the extension.

[0021] By adopting the above technical solution, setting the main positioning groove and the auxiliary positioning groove can improve the positioning accuracy and reduce injection molding defects caused by mold misalignment.

[0022] The present invention also discloses a vehicle, including a corner window, the outer periphery of which is covered by a flexible covering, and an upper positioning structure of the corner window according to any of the above-mentioned embodiments, wherein the upper positioning structure of the corner window is located at the upper part of the corner window and is at least partially covered within the flexible covering.

[0023] In summary, this utility model discloses an upper positioning structure for a corner window, including a corner window glass, a guide rail, and a positioning component. By replacing the traditional L-shaped sheet metal bracket with a positioning component, and then completing the corner window product through injection molding of a flexible covering, the positioning component, including its body, is not affected by the precision of the guide rail or injection molding deformation during injection molding.

[0046] Corner windows are a standard feature on vehicles. They are generally small in size, and common corner window structures include... Figure 2As shown, the corner window includes an L-shaped bracket 1, a metal guide rail 2, TPV coating 4, and glass 3. The traditional corner window's L-shaped bracket 1, metal guide rail 2, and metal frame are connected by spot welding. The welded components are then injected into an injection mold to complete the corner window production. However, due to limitations in the stamping and bending process precision and welding precision of the L-shaped bracket 1, if the L-shaped bracket 1 bends or deforms or is mispositioned during injection molding, the product consistency of the car door corner window will be poor. Furthermore, because of the poor positioning precision of the L-shaped bracket 1, it is prone to positional shifts and is easily deformed and damaged by the high pressure in the injection mold.

[0047] Therefore, to solve the problems of easy deformation of the bracket, poor installation positioning, and poor quality of the finished car door corner window due to the L-shaped bracket 1 in the existing technology, this utility model discloses an upper positioning structure for the corner window. It eliminates the traditional L-shaped bracket 1 and designs a positioning component with a frame structure to replace the L-shaped bracket 1. It adopts a combination of the positioning component with a frame structure and an anti-rotation positioning insert. This positioning component with a frame structure has the advantages of good product consistency, not easy deformation, quick and convenient installation, high matching degree, and accurate positioning. It also has significant effects on improving assembly efficiency, product quality, and appearance.

[0048] Next, the upper positioning structure of the corner window disclosed in this utility model will be described and explained in detail with reference to the accompanying drawings:

[0049] First, the coordinate system and directional relationships in this embodiment will be explained. The reference coordinate system and reference direction in this embodiment are based on the corner window glass as the reference object; therefore, please refer to... Figure 3 In this embodiment, the width direction refers to the width direction of the corner window glass 100, as shown in the figure below. Figure 3 As shown in direction A, the thickness direction is the thickness direction of the corner window glass 100, and the thickness direction is as follows. Figure 3 As shown in direction B, the height direction is the height direction of the corner window glass 100, and the height direction is as follows. Figure 3 As shown in the C direction.

[0050] Example 1

[0051] This embodiment discloses an upper positioning structure for a corner window. Please refer to [link / reference]. Figure 3 and Figure 4The corner window includes a corner window glass 100 and a flexible covering 200 disposed around the edge of the corner window glass 100. The upper positioning structure includes a guide rail 400 extending along the height direction C of the corner window glass 100 and a positioning member 300 extending along the width direction A of the corner window glass 100. The guide rail 400 is erected on the upper side of the corner window glass 100, and the positioning member 300 is disposed on the upper edge of the corner window glass 100. It should be noted that, in this application, the meaning of the positioning member 300 being disposed on the upper edge of the corner window glass 100 is that the lower end face of the positioning member 300 can at least partially directly abut against the upper edge of the corner window glass 100 and fit against one side of the corner window glass 100. In another implementation, at least a portion of the lower end face of the positioning component 300 may be spaced apart from the upper edge of the corner window glass 100 by a flexible covering component 200 (the flexible covering component may be, for example, silicone, TPV adhesive, polyurethane adhesive, butyl adhesive, etc.). Alternatively, in another implementation, the positioning component 300 may be placed above the upper edge of the corner window glass 100 with a gap between them. Those skilled in the art can adjust or design this according to actual needs, and this embodiment is not the only one.

[0052] More specifically, the positioning component 300 is preferably positioned with a gap or interval between the side of the guide rail 400 near the guide rail 400 and the upper end of the guide rail 400, and a flexible component, such as a flexible covering component 200, is also used to fill the space between the positioning component 300 and the upper end of the guide rail 400. Those skilled in the art can also make adjustments or designs according to actual needs, and this embodiment is not limited to this.

[0053] In a preferred implementation provided in this embodiment, see [link to previous text]. Figure 3 The guide rail 400 is erected along the width direction A of the corner window glass 100, near one side edge of the upper part of the corner window glass 100 (e.g., Figure 3 Positioned on the right side of the corner window glass 100, the positioning component 300 is positioned at the top of the corner window glass 100 along the height direction. After the positioning component 300, the corner window glass 100 and the guide rail 400 are placed in the mold for injection molding, a flexible covering component 200 is formed around the edge of the corner window glass 100. It should be noted that the covering area of ​​the flexible covering component 200 needs to be designed and formed in the mold according to the requirements of those skilled in the art, such as being set as semi-enclosed or fully enclosed, etc. This embodiment does not make specific limitations in this regard.

[0054] See further Figure 3 and Figure 5The positioning component 300 includes an integrally formed component body 310 and an insert mounting portion 320. The insert mounting portion 320 is located on the upper part of the component body 310, near the end of the guide rail 400. The component body 310 extends in the width direction, and the bottom wall 350 of the component body 310 (see...) Figure 6 The insert mounting portion 320 is at least partially abutting against the top edge of the corner window glass 100. An insert mounting groove 330 is provided on the insert mounting portion 320, and an anti-rotation positioning insert 500 is detachably disposed within the insert mounting groove 330. The axial direction of the anti-rotation positioning insert 500 is parallel to the height direction. Furthermore, the flexible covering 200 at least covers the side edge of the corner window glass 100, the guide rail 400, and the component body 310. That is, it must at least cover the side edge of the corner window glass 100, the guide rail 400, and the component body 310. The top of the insert mounting portion 320, as the mounting end face 600, protrudes from the flexible covering 200 (see [reference]). Figure 4 ).

[0055] It should be further noted that, in this application, the bottom wall 350 of the component body 310 at least partially abutting against the top edge of the corner window glass 100 means that the bottom wall 350 of the component body 310 can be configured, for example, with a width dimension that is the same as the top edge dimension of the corner window glass 100, or with a width dimension that is greater than the top edge dimension of the corner window glass 100, or with a width dimension that is less than the top edge dimension of the corner window glass 100. Those skilled in the art can adjust or design according to actual needs, and this embodiment does not specifically limit this.

[0056] It should be noted that the positioning component 300 and the anti-rotation positioning insert 500 are formed independently. The structure and volume of the component body 310 and the insert mounting part 320 can be adjusted according to different vehicle models or different corner window glass 100. In this embodiment, when the positioning component 300 with a skeleton structure is used, the contact area between the positioning component 300 and the corner window glass 100, and the contact area between the positioning component 300 and the flexible covering 200 are much larger than the contact area of ​​the traditional L-shaped sheet metal bracket. Therefore, its structural stability and positioning accuracy are also higher.

[0057] Through the design of the above structure, this utility model provides an upper positioning structure for a corner window. The traditional L-shaped sheet metal bracket is replaced by the positioning component 300 and the anti-rotation positioning insert 500. The corner window product is then completed by injection molding flexible covering 200. The positioning component 300 includes a component body 310. During injection molding, it is not affected by the accuracy of the guide rail 400 and the deformation of the injection molding. It has the advantages of small dimensional fluctuation, high stability and small deformation during injection molding.

[0058] Further, see reference. Figure 3 and Figure 6 Because the bottom wall 350 of the positioning component 300 abuts against the top edge of the corner window glass 100, the positioning component 300 and the corner window glass 100 support and abut against each other. This structure can better disperse and resist external forces, thereby improving the overall strength of the corner window structure. Furthermore, the component body 310 is set as a skeleton mechanism instead of an L-shape, resulting in small deformation and high stability during installation, injection molding, or other situations. It is easy to install and position, and the component body 310 with this structure is also simpler to manufacture and has a simpler structure. Therefore, the manufacturing process, structural strength, installation efficiency, and matching efficiency of the positioning component 300 in the upper positioning structure of the corner window disclosed in this application are greatly improved compared to the L-shaped stamped sheet metal bracket.

[0059] Those skilled in the art will understand that the flexible covering 200 includes, but is not limited to, any one of the following materials: TPV adhesive, polyurethane adhesive, butyl adhesive, and silicone adhesive. The flexible covering 200 is formed by injection molding around the edge of the corner window glass 100. Taking TPV adhesive as an example, TPV adhesive is suitable for higher temperatures, can withstand greater tensile forces, has good deformation capabilities, and is a non-polluting material that can be recycled. In a preferred embodiment, the guide rail 400 is a metal guide rail.

[0060] Further preferred, please refer to Figure 5 and Figure 6 In the upper positioning structure of the corner window disclosed in this embodiment, the lower part of the component body 310, along the edge in the width direction, is provided with an extension 340 extending toward the corner window glass 100. The inner wall of the extension 340 at least partially abuts against the corresponding side of the top of the corner window glass 100. It should be noted that the extension 340 and the component body 310 are integrally formed.

[0061] In actual production and use, the extension 340 can be provided on one side or on both sides as needed. When the extension 340 is provided on one side, as in the design scheme of this embodiment, one side of the extension 340 abuts against the glass. When the extension 340 is provided on both sides, the extensions 340 on both sides and the component body 310 form a "U" shape, and then the corner window glass 100 is embedded between the extensions 340 on both sides. This arrangement has higher structural stability, but requires higher precision. Those skilled in the art can design and select according to actual needs, and this embodiment does not make specific limitations in this regard.

[0062] The following description will be based on an example where an extension 340 is provided on one side of the component body 310. See [link to documentation]. Figure 3 and Figure 5The extension 340 and the component body 310 are integrally formed and generally have a rectangular plate-like structure. The insert mounting part 320 protrudes partially from the component body 310 and is positioned in the upper right corner as needed for convenient subsequent installation. Furthermore, the extension 340 of the positioning component 300 is also provided with a flow hole 342, a main positioning groove 343, and an auxiliary positioning groove 344. Please refer to [link to relevant documentation]. Figure 5 Each main positioning groove 343 is a circular hole that penetrates the extension 340, and each auxiliary positioning groove 344 is an oblong hole that penetrates the extension 340 and extends along the length of the extension 340. The main positioning groove 343 and the auxiliary positioning groove 344 are used for positioning.

[0063] More preferably, see Figure 6 The inner wall of the extension 340 is provided with a plurality of abutment protrusions 341 facing the corner window glass 100 at intervals. Specifically, those skilled in the art can provide 3, 4, 5 or even more abutment protrusions 341 according to actual needs, and this embodiment does not make a specific limitation in this regard.

[0064] Specifically, the extension 340 provided at the lower part of the component body 310 can increase the contact area between the extension and the corner window glass 100, which can enhance the stability of the structure and reduce the shaking and deformation of the corner window glass 100. Furthermore, the several abutting protrusions 341 provided at intervals on the inner wall of the extension 340 can make the force on the corner window glass 100 more uniform, and make there a gap between the relative surfaces of the extension 340 and the corner window glass 100. Therefore, when the flexible covering 200 is injection molded, the injection molten material will flow into the gap (for example, through the molten material hole 342), thereby making the connection between the corner window glass 100 and the extension 340 tighter and more stable.

[0065] More specifically, it should be noted that in this embodiment, after the abutment protrusion 341 is provided, if the glue runs to the back of the positioning component 300 during the injection molding process, it will push the positioning component 300 off-center. At this time, the abutment protrusion 341 needs to hold the corner window glass 100 in place to prevent the insert from shifting. Therefore, there will be a very small gap between the abutment protrusion 341 and the corner window glass 100, preferably controlled within 1mm, for example, the gap is set to 0.2mm, 0.3mm, 0.5mm, etc.

[0066] This embodiment also discloses an upper positioning structure for a corner window. In the thickness direction B of the corner window glass 100, the thickness of the component body 310 and the insert mounting portion 320 are the same and greater than the thickness of the extension portion 340. The purpose of this design is to form a stepped portion on the bottom wall 350 of the component body 310 and the insert mounting portion 320, with the corner window glass 100 abutting against the stepped portion. The bottom wall 350 of the component body 310 and the insert mounting portion 320 is adapted to the top edge of the corner window glass 100, and when viewed along the thickness direction B of the corner window glass 100, the bottom wall 350 presents a smooth transition surface adapted to the top edge of the corner window glass 100.

[0067] Specifically, the thickness dimensions of the component body 310 and the insert mounting portion 320 (e.g.) Figure 6 As shown, the dimension in the thickness direction indicated by arrow B in the figure is greater than the thickness dimension of the extension 340 (e.g., Figure 6 As shown in the figure (in the thickness direction indicated by arrow B), the part body 310, the insert mounting portion 320, and the extension portion 340 are joined by an abutment step 345. The top of the corner window glass 100 abuts against the step surface of the abutment step 345. This structure facilitates the abutment installation of the corner window glass 100. For example, if the thickness of the corner window glass 100 is 3mm, then the thickness of the part body 310 and the insert mounting portion 320 must be at least equal to or greater than the thickness of the extension portion 340 by 3mm, such as 3.5mm or 4mm. The smooth transition surface of the bottom wall 350 of the part body 310 and the insert mounting portion 320 is actually adapted to the top surface of the glass. Figure 6 As shown, in this embodiment, the bottom wall 350 of the insert mounting portion 320 has a larger curve radius than the bottom wall 350 of the component body 310, thereby achieving a tight fit with the corner window glass 100. Using this technical solution, the bottom wall 350 has a smooth transition surface that adapts to the top edge of the corner window glass 100, which optimizes visual aesthetics, improves sealing performance, facilitates installation, and enhances structural stability.

[0068] This embodiment also discloses an upper positioning structure for a corner window; please refer to [link / reference]. Figure 5 and Figure 6 The extension 340 is also provided with a flow hole 342, which includes a flow hole in the width direction (e.g., Figure 3 Multiple flow holes 342 are spaced apart on the width direction A) of the center corner window glass 100. A portion of the flow holes 342 extend through the extension portion 340 along the width direction, while another portion extends through the extension portion 340 along the height direction. The flow holes 342 can absorb excess injection material during injection molding and also reduce the weight of the positioning component 300.

[0069] Specifically, taking the positioning component 300 disclosed in this embodiment as an example, there are 3 material flow holes 342 extending through the extension portion 340 in the height direction and arranged at intervals, and only 1 material flow hole 342 extending through the extension portion 340 in the width direction. Those skilled in the art can also adjust it according to actual needs, such as 2 in the width direction and 2 in the height direction. This embodiment will not elaborate on this.

[0070] The following example illustrates the insert mounting groove 330 and the anti-rotation positioning insert 500 in the upper positioning structure of the corner window disclosed in this embodiment:

[0071] Please see Figure 5 The insert mounting groove 330 is a mounting hole extending downwards from the top, with multiple serrated protrusions evenly arranged circumferentially on the inner peripheral wall of the mounting hole; the anti-rotation positioning insert 500 includes an insert nut that can be fitted into the mounting hole, and a fixing hole is provided in the center of the insert nut. See further. Figure 7 The insert nut includes a first star-shaped anti-rotation shaft section 510, a middle shaft section 520, and a second star-shaped anti-rotation shaft section 530 integrally formed along the axial direction. The outer periphery of both the first and second star-shaped anti-rotation shaft sections 510 and 530 is provided with multiple serrated grooves 540 that mate with multiple serrated protrusions. Furthermore, the diameters of the first and second star-shaped anti-rotation shaft sections 510 and 530 are larger than the diameter of the middle shaft section 520. It should also be noted that a shaft hole is provided at the center of the insert nut, and an internal thread can be formed in the shaft hole to facilitate subsequent threaded connection with threaded components.

[0072] The design of the above structure, with the star-shaped insert nut, has high anti-rotation capability, anti-slip capability and durability. The star-shaped anti-rotation insert nut can remain stable under heavy loads or vibration environments, and is not easy to loosen or fall off. It is also easy to install and is not easy to loosen during long-term use.
