Abstract
Description
Technical Field
[0001] This application relates to the field of connecting component technology, specifically to a pre-embedded stud structure, a vehicle corner window, and a vehicle. Background Technology
[0002] Pre-embedded stud structures are widely used in the automotive industry. For example, when installing automotive corner window glass, the base plate of the pre-embedded stud structure is embedded in the injection-molded part around the corner window glass, and the studs connected to the base plate protrude from the injection-molded part. The corner window glass and the injection-molded part are then fixed to the vehicle body using nuts and bolts. However, current pre-embedded stud structures typically use projection welding or riveting to connect the studs to the base plate, and the contact area between the base plate and the injection-molded part is relatively small. During corner window glass installation, this structure is prone to problems such as stud detachment and stud or base plate rotation, thus affecting the installation quality. Utility Model Content
[0003] In view of the above, it is necessary to propose a pre-embedded stud structure for vehicle corner windows and vehicles to reduce the probability of studs falling off or the studs or base plate rotating, and to improve the installation quality.
[0004] This application provides a pre-embedded stud structure, including a stud and a base plate. The stud and the base plate are connected by a cold forging process, and the stud is perpendicular to the base plate. An overflow hole is provided on the base plate.
[0005] In some embodiments, there are multiple overflow holes arranged around the stud.
[0006] In some embodiments, a positioning groove is provided on the peripheral sidewall of the base plate, and the positioning groove is located on one side of the overflow hole.
[0007] In some embodiments, there are multiple positioning slots, which are arranged around the stud.
[0008] In some embodiments, the base plate has a connecting hole located on one side of the overflow hole, and the stud is inserted into the connecting hole by a cold forging process to be fixedly connected to the base plate; wherein, the inner wall of the connecting hole has an anti-rotation groove, and the end of the stud inserted into the connecting hole has a limiting part that extends into the anti-rotation groove; and / or, the cross-sectional shape of the connecting hole is polygonal.
[0009] In some embodiments, the peripheral sidewall of the base plate includes two opposing first sidewalls and two opposing second sidewalls, with each end of the first sidewall connected to the two second sidewalls respectively, and the ratio of the length of the first sidewall to the length of the second sidewall is in the range of 2-4.
[0010] In some embodiments, the portion where each of the first side surfaces connects to the adjacent second side surface is an arcuate structure.
[0011] In some embodiments, the base plate has a limiting protrusion on the side facing the stud and / or the side of the base plate away from the stud.
[0012] The embedded stud structure in this embodiment connects the stud to the base plate via cold forging, resulting in a more secure connection and improved overall mechanical properties. Compared to studs welded to the base plate, this reduces the likelihood of stud detachment; compared to studs riveted to the base plate, it reduces the likelihood of stud rotation. Furthermore, the inclusion of overflow holes facilitates overflow of the injection molded part during injection, increasing the contact area between the base plate and the injection molded part, further reducing the likelihood of base plate rotation. In addition, the embedded stud structure in this embodiment reduces the likelihood of stud detachment or stud / base plate rotation, thereby improving installation quality.
[0013] This application also provides a vehicle corner window, including a corner window glass, an injection molded part, and a pre-embedded stud structure as described above. The injection molded part is connected to the corner window glass, and the base plate is embedded in the injection molded part.
[0014] The vehicle corner window in this embodiment of the application reduces the probability of studs falling off or the studs or base plate rotating by setting the above-mentioned pre-embedded stud structure, thereby improving the installation quality.
[0015] This application also provides a vehicle, including the vehicle corner window as described above.
[0016] The vehicle in this embodiment of the application, by setting a vehicle corner window including the above-mentioned pre-embedded stud structure, reduces the probability of studs falling off or studs or base plates rotating, thereby improving the installation quality.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0027] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0028] Please see Figure 1 , Figure 4 and Figure 6 This application provides a pre-embedded stud structure 1, which can be used as a connecting component for a vehicle 1000, electrical appliances, etc. For ease of understanding, this application uses the application of the pre-embedded stud structure 1 to the corner window 100 of the vehicle 100 as an example for illustration. Obviously, this is not a limitation of this application.
[0029] Please see Figure 1 In this embodiment, the pre-embedded stud structure 1 includes a base plate 10 and a stud 20. The stud 20 is connected to the base plate 10 by a cold forging process, and the stud 20 is perpendicular to the base plate 10. An overflow hole 11 is provided on the base plate 10.
[0030] Cold heading is a metalworking method performed at room temperature. It involves applying external force to cause plastic deformation of the metal within a mold, thereby forming the desired part or blank. This process is widely used in manufacturing standard fasteners such as bolts, screws, nuts, and rivets. Workpieces produced by cold heading have good mechanical properties. During cold heading, the metal material undergoes plastic deformation, and its internal grains deform and recrystallize along the deformation direction. This deformation process causes the material's fibrous structure to distribute along the shape of the part, thus improving its mechanical properties.
[0031] Therefore, by connecting the stud 20 to the base plate 10 through cold forging, the connection between the stud 20 and the base plate 10 is made more secure, and the overall mechanical properties of the pre-embedded stud structure 1 are improved. Compared with the method of projecting the stud 20 to the base plate 10, the probability of the stud 20 falling off is reduced; compared with the method of riveting the stud 20 to the base plate 10, the probability of the stud 20 rotating is reduced. In addition, by providing the overflow hole 11, it is convenient for the injection molded part 3 (such as...) Figure 4 As shown, during injection molding, the material overflows into the overflow hole 11, thereby increasing the contact area between the base plate 10 and the injection molded part 3, and thus reducing the probability of the base plate 10 rotating. In addition, since the pre-embedded stud structure 1 of this embodiment reduces the probability of stud 20 falling off or stud 20 or base plate 10 rotating, the installation quality is improved.
[0032] In this embodiment, the extension direction of the overflow hole 11 is the same as the extension direction of the stud 20. Thus, when the stud 20 is subjected to force, the portion of the injection molded part 3 extending into the overflow hole 11 can exert a greater restraining force, thereby reducing the probability of the base plate 10 rotating.
[0033] In this embodiment, there are multiple overflow holes 11, which are spaced apart around the stud 20. By providing multiple overflow holes 11, the contact area between the base plate 10 and the injection molded part 3 is further increased, and the multiple overflow holes 11 can cooperate with the injection molded part 3 to simultaneously restrict the rotation of the base plate 10 relative to the injection molded part 3 from multiple positions, thereby reducing the probability of the base plate 10 rotating with the injection molded part 3.
[0034] In this embodiment, the peripheral sidewall 12 of the base plate 10 includes two oppositely arranged first sidewalls 121 and two oppositely arranged second sidewalls 122. The two ends of each first sidewall 121 are respectively connected to the two second sidewalls 122. The ratio of the length of the first sidewall 121 to the length of the second sidewall 122 is in the range of 2-4.
[0035] This configuration makes the cross-sectional shape of the base plate 10 approximately rectangular. Furthermore, by setting the ratio of the length of the first side 121 to the length of the second side 122 to a range of 2-4, the contact area between the base plate 10 and the injection molded part 3 is increased while ensuring the structural strength of the base plate 10, and the restraining force of the injection molded part 3 on both ends of the base plate 10 is improved, thereby reducing the probability of the base plate 10 rotating.
[0036] In this embodiment, since the pre-embedded stud structure 1 is applied to the vehicle 1000, the size of the base plate 10 cannot be too large. The length range of the first side 121 is 1cm-6cm, and the length range of the second side 122 is 0.5cm-1.5cm.
[0037] In this embodiment, the portion connecting each first side 121 to the adjacent second side 122 is an arc-shaped structure 123. This design reduces the probability that the base plate 10 will cut the injection molded part 3 and rotate under stress, thereby reducing the probability that the base plate 10 will rotate along with it.
[0038] In this embodiment, a positioning groove 1211 is provided on the peripheral sidewall 12 of the base plate 10. The positioning groove 1211 is located on one side of the overflow hole 11, and is specifically provided on the first side surface 121. By providing the positioning groove 1211, the contact area between the base plate 10 and the injection molded part 3 is further increased, and the part of the injection molded part 3 that extends into the positioning groove 1211 cooperates with the positioning groove 1211 to position the base plate 10, thereby reducing the probability of the base plate 10 detaching from the injection molded part 3 and the base plate 10 rotating.
[0039] In this embodiment, there are multiple positioning grooves 1211, which are spaced apart around the stud 20. By providing multiple positioning grooves 1211, the contact area between the base plate 10 and the injection molded part 3 is further increased, and the multiple positioning grooves 1211 can cooperate with the injection molded part 3 to simultaneously restrict the rotation of the base plate 10 relative to the injection molded part 3 from multiple positions, thereby reducing the probability of the base plate 10 detaching from the injection molded part 3 and the base plate 10 rotating along with it.
[0040] Please refer to the following: Figure 2In this embodiment, the base plate 10 has a connecting hole 13, which is located on one side of the overflow hole 11. The stud 20 is inserted into the connecting hole 13 by cold forging to fix it to the base plate 10. The inner wall of the connecting hole 13 has an anti-rotation groove 131. The end of the stud 20 inserted into the connecting hole 13 has a limiting part 21, which extends into the anti-rotation groove 131.
[0041] Specifically, when the stud 20 is inserted into the connecting hole 13 through the cold forging process, the end of the stud 20 inserted into the connecting hole 13 is deformed under the squeezing action of the inner wall of the connecting hole 13. After a portion of it is deformed, a limiting part 21 is formed and extends into the anti-rotation groove 131. The anti-rotation groove 131 and the limiting part 21 cooperate to restrict the stud 20 from rotating relative to the base plate 10 under the action of external force, thereby reducing the probability of the stud 20 rotating.
[0042] In this embodiment, there are multiple anti-rotation grooves 131, which are spaced apart along the circumference of the connecting hole 13 on the inner wall of the connecting hole 13. Correspondingly, there are also multiple limiting parts 21, which extend into the multiple anti-rotation grooves 131. In this way, the multiple limiting parts 21 and the multiple anti-rotation grooves 131 cooperate to simultaneously restrict the stud 20 from rotating relative to the base plate 10 under the action of external force from multiple positions, thereby reducing the probability of the stud 20 rotating.
[0043] In other embodiments, the cross-sectional shape of the connecting hole 13 is polygonal, such as triangular, rectangular, pentagonal, hexagonal, etc. When the stud 20 is inserted into the connecting hole 13 by cold forging, the end of the stud 20 inserted into the connecting hole 13 deforms under the squeezing action of the inner wall of the connecting hole 13 and abuts against each inner wall of the connecting hole 13. Since the cross-sectional shape of the connecting hole 13 is polygonal, the stud 20 is restricted from rotating relative to the base plate 10 under the action of external force, thereby reducing the probability of the stud 20 rotating.
[0044] Of course, in some other embodiments, the cross-sectional shape of the connecting hole 13 can be set to be polygonal, and an anti-rotation groove 131 can be opened on the inner wall of the connecting hole 13 to further reduce the probability of the stud 20 rotating.
[0045] Please refer to the following: Figure 3 In another embodiment, the base plate 10 has a limiting protrusion 14 on the side facing the stud 20. By setting the limiting protrusion 14, the contact area between the base plate 10 and the injection molded part 3 is further increased, and the friction and bonding force between the base plate 10 and the injection molded part 3 are also increased, thereby reducing the probability of the base plate 10 detaching from the injection molded part 3 and reducing the probability of the base plate 10 rotating.
[0046] In other embodiments, a limiting protrusion 14 may be provided on the side of the base plate 10 away from the stud 20, or a limiting protrusion 14 may be provided on both the side of the base plate 10 facing the stud 20 and the side of the base plate 10 away from the stud 20. This application embodiment does not specifically limit this.
[0047] In summary, the pre-embedded stud structure 1 of this application embodiment connects the stud 20 and the base plate 10 through a cold forging process, making the connection between the stud 20 and the base plate 10 more secure and improving the overall mechanical properties of the pre-embedded stud structure 1. This reduces the probability of the stud 20 falling off and the probability of the stud 20 rotating. Furthermore, by providing an overflow hole 11, the injection molded part 3 can overflow into the overflow hole 11 during injection molding, thereby increasing the contact area between the base plate 10 and the injection molded part 3, further reducing the probability of the base plate 10 rotating. In addition, because the pre-embedded stud structure 1 of this application embodiment reduces the probability of the stud 20 falling off or the stud 20 or the base plate 10 rotating, the installation quality is improved. Furthermore, by opening a positioning groove 1211 on the peripheral sidewall 12 of the base plate 10, the probability of the base plate 10 rotating is further reduced; by opening a connecting hole 13 on the base plate 10 and opening an anti-rotation groove 131 on the inner wall of the connecting hole 13, the probability of the stud 20 rotating is further reduced.
[0048] Please refer to the following: Figure 4 and Figure 5 This application embodiment also provides a vehicle corner window 100, including a corner window glass 2, an injection molded part 3, and a pre-embedded stud structure 1 as described above. The injection molded part 3 is connected to the corner window glass 2. Specifically, the injection molded part 3 is wrapped around the corner window glass 2 by an injection molding process, and the base plate 10 is embedded in the injection molded part 3.
[0049] The vehicle corner window 100 of this application embodiment reduces the probability of studs 20 falling off or studs 20 or base plate 10 rotating by setting the above-mentioned pre-embedded stud structure 1, thereby improving the installation quality.
[0050] Please refer to the following: Figure 6 This application also provides a vehicle 1000, including the vehicle corner window 100 as described above.
[0051] Specifically, the vehicle 1000 also includes a body 200, and the vehicle corner window 100 is installed on the body 200 by bolts (not shown) cooperating with the studs 20 of the pre-embedded stud structure 1.
[0052] The vehicle 1000 of this application embodiment reduces the probability of studs 20 falling off or studs 20 or base plate 10 rotating by setting a vehicle corner window 100 including the above-mentioned pre-embedded stud structure 1, thereby improving the installation quality.
