Description

Technical Field

[0001] This application relates to the field of transportation technology, and more particularly to a bracket assembly, a glass assembly, and a transportation vehicle. Background Technology

[0002] Currently, car rearview mirrors are typically attached to the windshield via a base. As cars become increasingly intelligent and feature-rich, the number of electronic components such as cameras, radars, and antennas continues to rise. These components are often mounted on the windshield using independent brackets, but limited interior space makes it difficult to accommodate the independent installation of multiple electronic components. To save space, integrated structures that integrate these electronic components into the rearview mirror arm exist. However, this integrated structure increases the load on the rearview mirror base. Conventional rearview mirror bases are usually fixed to the windshield using solid adhesives (such as 3M adhesive). The increased weight of the rearview mirror assembly, coupled with long-term load, can easily cause the adhesive between the base and the windshield to fail, creating gaps. In severe cases, this can even lead to cracking or breakage of the windshield, posing a significant safety hazard. Summary of the Invention

[0003] This application provides a bracket assembly, a glass assembly, and a vehicle that integrates rearview mirrors and electronic components, saving interior space in the vehicle and increasing the load-bearing capacity of the rearview mirror base.

The number of protrusions is at least three.

[0010] In one embodiment, the height of the protrusion is greater than or equal to 0.6 mm and less than or equal to 1.0 mm.

[0011] In one embodiment, the base further includes a plurality of vent holes, all of which penetrate the first surface and the second surface. The plurality of vent holes are spaced apart from each other and avoid the plurality of protrusions and the plurality of solid adhesives. The number of vent holes is at least three.

[0012] In one embodiment, the mounting bracket further includes a plurality of through holes, all of which penetrate the mounting bracket along its thickness direction.

[0022] In existing technologies, as the level of automotive intelligence continues to increase, the number of various electronic components such as in-vehicle cameras, radars, and antennas is constantly increasing. These electronic components are mostly mounted on the windshield using independent brackets. However, the limited space inside the vehicle makes it difficult to meet the independent installation needs of multiple types of electronic components. To save interior space, there are existing integrated structures that integrate in-vehicle electronic components into the rearview mirror arm. However, this integrated structure increases the load on the rearview mirror base. Conventional rearview mirror bases are mostly fixed to the windshield using solid adhesives (such as 3M adhesive). With the increased weight of the rearview mirror assembly, long-term load can easily cause the adhesive between the base and the windshield to fail, resulting in gaps. In severe cases, it can even cause the windshield to crack or break, posing a significant driving safety hazard.

The mounting bracket is integrally molded by injection molding and covers at least part of the outer side of the rearview mirror base, so that the rearview mirror base and the mounting bracket can be fixedly connected. Even if the weight of the rearview mirror increases, leading to an increase in the load on the base, or if the information acquisition element is integrated into the rearview mirror, leading to an increase in the load on the base, the mounting bracket can help the base distribute the load, avoiding problems such as adhesion failure, delamination, and gaps caused by the base being bonded separately to the window glass. It also avoids the risk of window glass cracking or breaking due to the stress concentration of the adhesive between the base and the window glass, thus improving driving safety.

The bracket assembly 100 is located on the side of the window glass 300 near the top of the vehicle 1000.

[0035] The vehicle window glass 300 can be, but is not limited to, a windshield. In this embodiment, the vehicle window glass 300 is illustrated using the windshield of a vehicle as an example. The windshield is approximately trapezoidal in shape. That is, the width of the vehicle window glass 300 near the bottom of the vehicle 1000 is greater than the width of the vehicle window glass 300 near the top of the vehicle 1000. Moreover, the windshield has a certain curvature and is curved glass.

[0036] Please refer to the following: Figure 2 and Figure 3 , Figure 3 for Figure 2 The diagram shows the structural schematic of the support assembly.

[0037] The bracket assembly 100 includes a mounting bracket 10, a rearview mirror 20, and an information acquisition element (not shown). The information acquisition element is mounted on the rearview mirror 20 or the mounting bracket 10. The rearview mirror 20 is mounted on the mounting bracket 10. The mounting bracket 10 is mounted on the inner glass surface 301 of the vehicle window 300. The rearview mirror 20 is used by the driver to observe the road conditions behind or to the side of the vehicle 1000, assisting the driver in controlling the vehicle 1000 to change lanes, reverse, and anticipate the driving status of vehicles 1000 behind, ensuring safe driving visibility. The information acquisition element is used for image acquisition, navigation, etc., thereby assisting in driving the vehicle 1000 or enabling automatic driving of the vehicle 1000.

[0038] The information acquisition element may be, but is not limited to, visible light cameras, near-infrared cameras, thermal imagers, rain sensors, lidar, millimeter-wave radar, ultrasonic radar, vehicle communication equipment, antenna boxes, and other electronic components. In this embodiment, a camera is used as an example for illustration.

[0039] The rearview mirror 20 includes a base 21, a mirror arm 23, and a mirror body 24. The base 21 is mounted on a mounting bracket 10. The mirror arm 23 is mounted on the base 21. The mirror body 24 is mounted on the end of the mirror arm 23 away from the base 21. The mirror body 24 has a mirror surface 241 facing the rear or rear-side of the vehicle 1000 to reflect road conditions behind or to the rear of the vehicle 1000 for the driver to observe in real time. When an information acquisition element is mounted on the rearview mirror 20, the information acquisition element is fixed to the mirror arm 23. In this embodiment, the base 21 can be made of materials with high structural strength, such as aluminum alloy, to enable the base 21 to withstand large loads for a long time, ensuring structural stability and extending its service life.

[0040] In this embodiment, the mounting bracket 10 is made of plastic, which can be injection molded and covers at least part of the outer side of the base 21. The structural design of the mounting bracket 10 varies depending on the structure of the base 21. The structure of the base 21 and the mounting bracket 10 will be described schematically below with reference to seven embodiments of the bracket assembly 100.

[0041] Please refer to the following: Figure 4 and Figure 5 , Figure 4 for Figure 3 The diagram shows a partial structural design of the first embodiment of the support assembly. Figure 5 for Figure 4 The diagram shows a partial structural view of the support assembly from another angle. Among them, Figure 4 and Figure 5 The image does not show the mirror arm and mirror body of the rearview mirror in the bracket assembly; it only shows an assembly relationship between the base and the mounting bracket.

[0042] The mounting bracket 10 includes a mounting surface 11 and an adhesive surface 12. The mounting surface 11 and the adhesive surface 12 are disposed facing away from each other along the thickness direction of the mounting bracket 10. In this embodiment, the mounting bracket 10 is generally a rectangular plate structure.

[0043] The mounting bracket 10 also includes a mounting boss 13 and a mounting recess 14. The mounting boss 13 protrudes from the mounting surface 11. The mounting boss 13 includes a boss surface 131. The boss surface 131 faces away from the mounting surface 11. The mounting recess 14 is recessed into the boss surface 131 of the mounting boss 13. The mounting recess 14 is used to receive a portion of the base 21 and is fitted and fixed to the base 21. In this embodiment, the mounting boss 13 is generally a cylindrical boss. The mounting recess 14 is generally a circular recess.

[0044] Optionally, such as Figure 5 As shown, the mounting bracket 10 also includes a recessed groove 15. The recessed groove 15 is recessed into the adhesion surface 12. Along the thickness direction of the mounting bracket 10, the recessed groove 15 and the mounting groove 14 are spaced apart, and the projection of the recessed groove 15 is completely within the projection of the mounting boss 13. A reinforcing rib 16 protrudes from the bottom wall of the recessed groove 15. Both ends of the reinforcing rib 16 in the length direction are connected to the side wall of the recessed groove 15. The reinforcing rib 16 is used to support the bottom wall of the recessed groove 15, that is, to support the base 21 installed in the mounting groove 14, and to prevent the base 21 from crushing the recessed groove 15. The number of reinforcing ribs 16 is one or more. In this embodiment, the recessed groove 15 is approximately a circular groove. The reinforcing rib 16 is approximately a rectangular plate. The number of reinforcing ribs 16 is four, and the four reinforcing ribs 16 are arranged in a "well" shape to improve the support for the bottom wall of the recessed groove 15.

[0045] The base 21 includes a first surface 211, a second surface (not shown), and a peripheral side surface 213. The first surface 211 and the second surface are arranged facing away from each other along the thickness direction of the base 21. The peripheral side surface 213 is connected to the first surface 211 and the second surface. The first surface 211 of the base 21 has a locking protrusion 214. The locking protrusion 214 is used to lock and fix with the arm 23 of the rearview mirror 20. In this embodiment, the base 21 is generally a circular block.

[0046] The base 21 also includes a positioning groove 215. The positioning groove 215 is recessed on the peripheral side surface 213 and is recessed towards the axis of the base 21. The positioning groove 215 penetrates the first surface 211 and the second surface. That is, the positioning groove 215 is located at the edge of the base 21. The positioning groove 215 is used for assembly and positioning with the arm 23 of the rearview mirror 20. In this embodiment, the positioning groove 215 is approximately an arc-shaped groove, and there is only one positioning groove 215.

[0047] In this embodiment, the mounting bracket 10 is injection molded and covers at least a portion of the outer side of the base 21. Specifically, the base 21 is at least partially embedded in the mounting groove 14 of the mounting bracket 10. The sidewalls of the mounting groove 14 surround and connect to the peripheral side surface 213 of the base 21. The bottom wall of the mounting groove 14 connects to the second surface of the base 21. The first surface 211 of the base 21 exposes the mounting groove 14. The base 21 and the mounting bracket 10 are fixedly connected through the mounting groove 14. The telescope arm 23 is mounted on the base 21 and locked to the base 21 by the locking protrusion 214. The lens body 24 is mounted on the end of the telescope arm 23 away from the base 21.

[0048] The bracket assembly 100 is mounted on the vehicle window glass 300, with the mirror surface 241 of the rearview mirror 20 facing the rear or side-rear of the vehicle 1000, allowing the driver to observe the road conditions behind or to the side of the vehicle 1000. An adhesive layer (not shown) is provided on the adhesion surface 12 of the mounting bracket 10, enabling the mounting bracket 10 to adhere to the inner glass surface 301 of the vehicle window glass 300. The adhesive layer can be, but is not limited to, polyurethane resin (i.e., PU adhesive). After curing, the PU adhesive exhibits high structural bonding strength and load-bearing capacity, and can withstand long-term static loads and dynamic vibrations during driving, preventing problems such as adhesion failure, delamination, and gaps between the mounting bracket 10 and the vehicle window glass 300, thus ensuring the safety of the vehicle 1000 during driving. Furthermore, the PU adhesive possesses excellent elastic cushioning capabilities, dispersing the weight and stress of the bracket assembly 100 through its own deformation. Compared to using solid adhesives (such as 3M adhesive) to bond the window glass 300 and the mounting bracket 10, the PU adhesive in this embodiment effectively avoids the risk of stress concentration between the mounting bracket 10 and the window glass 300, leading to cracking or breakage of the window glass 300. In addition, the PU adhesive has strong gap-filling capabilities, filling the tiny gaps between the window glass 300 and the mounting bracket 10, preventing moisture and dust from entering these gaps and causing bonding failure between the window glass 300 and the mounting bracket 10.

[0049] Please see Figure 6 , Figure 6 for Figure 3 A schematic diagram of the base structure of the second embodiment of the bracket assembly shown.

[0050] Unlike the first embodiment of the bracket assembly 100 described above, the base 21 and the mounting bracket 10 in this embodiment have different structures.

[0051] Specifically, in this embodiment, the second surface 212 of the base 21 is provided with a mounting protrusion 216. The mounting protrusion 216 includes a mounting side surface 217. The mounting side surface 217 is connected to the second surface 212. The mounting side surface 217 of the mounting protrusion 216 is recessed with a snap-fit ​​groove 218, and the snap-fit ​​groove 218 is recessed in the axial direction of the mounting protrusion 216. In this embodiment, the snap-fit ​​groove 218 is approximately an annular groove. The mounting protrusion 216 with the snap-fit ​​groove 218 is approximately a cylinder with a "T" shaped cross-section.

[0052] The mounting groove 14 has a snap-fit ​​protrusion (not shown) on its sidewall. The snap-fit ​​protrusion extends along the axis of the mounting groove 14. The snap-fit ​​protrusion is used to engage with the snap-fit ​​groove 218 of the base 21, and its shape is adapted to the snap-fit ​​groove 218. In this embodiment, the snap-fit ​​protrusion is approximately an annular protrusion.

[0053] In this embodiment, when the base 21 and the mounting bracket 10 are formed, the plastic used to make the mounting bracket 10 is embedded in the snap-fit ​​groove 218 to form a snap-fit ​​protrusion. That is, after the base 21 and the mounting bracket 10 are formed, the snap-fit ​​protrusion is received in the snap-fit ​​groove 218, realizing the snap-fit ​​fixation between the base 21 and the mounting bracket 10, improving the connection strength between the base 21 and the mounting bracket 10, and ensuring the structural stability of the bracket assembly 100.

[0054] It should be noted that the structure in this embodiment is the same as that in the first embodiment of the bracket assembly 100 described above, and will not be repeated here.

[0055] Please refer to the following: Figure 7 , Figure 8 and Figure 9 , Figure 7 for Figure 3 The diagram shows a partial structural design of a third embodiment of the bracket assembly. Figure 8 for Figure 7 The diagram shows a partial structural view of the bracket assembly from another angle. Figure 9 for Figure 8 The diagram shows the structural design of the base of the bracket assembly from another angle. Among them, Figure 7 and Figure 8 The rearview mirror arm and mirror body of the bracket assembly are not shown; only the assembly relationship between the base and the mounting bracket is shown.

[0056] Unlike the first embodiment of the bracket assembly 100 described above, the structures of the base 21 and the mounting bracket 10 in this embodiment are different from those in the first embodiment. In this embodiment, both the base 21 and the mounting bracket 10 are bonded and fixed to the vehicle window glass 300 by an adhesive layer (not shown). It is understood that the second surface 212 of the base 21 and the adhesive surface 12 of the mounting bracket 10 are both used to apply the adhesive layer.

[0057] Specifically, such as Figure 7 and Figure 8 As shown, mounting bracket 10 is not equipped with the following features: Figure 4 and Figure 5 The mounting boss 13, the recess 15, and the mounting groove 14 shown include a mounting through hole 17. The mounting through hole 17 extends through the adhesion surface 12 and the mounting surface 11 of the mounting bracket 10. The mounting through hole 17 is used to receive at least a portion of the base 21.

[0058] like Figure 8 As shown, the mounting bracket 10 also includes an isolation rib 18. The isolation rib 18 protrudes from the adhesion surface 12 and surrounds the outer periphery of the mounting through hole 17. The isolation rib 18 is used to separate the second surface 212 of the base 21 from the adhesion surface 12 of the mounting bracket 10, that is, to block the adhesive layer on the base 21 and to isolate the areas on the base 21 and the mounting bracket 10 used for applying the adhesive layer. In this embodiment, the mounting through hole 17 is approximately a circular hole, and the isolation rib 18 is approximately a circular protrusion.

[0059] like Figure 9 As shown, the second surface 212 of the base 21 includes an adhesive surface 2121 and a connecting surface 2122. The connecting surface 2122 surrounds and connects to the edge of the adhesive surface 2121, and the connecting surface 2122 is connected to the peripheral side surface 213. In this embodiment, the adhesive surface 2121 is approximately a circular surface, and the connecting surface 2122 is approximately an annular surface.

[0060] The adhesive surface 2121 is provided with a plurality of protrusions 219. These protrusions 219 are spaced apart from each other around the axis of the base 21. Each protrusion 219 serves to support the inner glass surface 301 of the window glass 300, limiting the thickness of the adhesive layer between the inner glass surface 301 and the adhesive surface 2121, and ensuring the uniformity of the adhesive layer thickness. In this embodiment, the height of the protrusions 219 is greater than or equal to 0.6 mm and less than or equal to 1.0 mm to avoid the protrusions 219 being too short, resulting in a thin adhesive layer and poor cushioning ability for the base 21, making it easy for the base 21 to collide with the window glass 300 and cause it to break. Simultaneously, it also avoids the protrusions 219 being too high, resulting in a thick adhesive layer and preventing the adhesive layer from occupying too much space in the thickness direction of the window glass 300. The number of protrusions 219 is greater than or equal to three to ensure the stability of the base 21 supporting the window glass 300.

[0061] The base 21 has three positioning slots 215. The three positioning slots 215 are spaced apart from each other around the axis of the base 21, and all three positioning slots 215 penetrate the connecting surface 2122 and the first surface 211. Compared with a single positioning slot 215, three positioning slots 215 can further position and fix the mirror arm 23 of the rearview mirror 20 to the base 21, thereby improving the assembly accuracy of the mirror arm 23 and the base 21.

[0062] In this embodiment, the mounting bracket 10 is injection molded, and the base 21 is embedded in and fixed to the mounting bracket 10. Specifically, the base 21 is housed within the mounting through hole 17 of the mounting bracket 10, and at least a portion of the first surface 211 and at least a portion of the second surface 212 are exposed within the mounting through hole 17. That is, the mounting bracket 10 does not need to completely cover the first surface 211 and the second surface 212 of the base 21, which reduces the space occupied by the base 21 in the thickness direction of the mounting bracket 10 to a certain extent. The first surface 211 of the base 21 faces the same direction as the mounting surface 11 of the mounting bracket 10. The second surface 212 of the base 21 faces the same direction as the adhesion surface 12 of the mounting bracket 10. The edge of the base 21 is embedded in the hole wall of the mounting through hole 17, that is, the peripheral side surface 213 of the base 21 is completely covered by the mounting bracket 10, and a portion of the connecting surface 2122 and a portion of the first surface 211 of the base 21 are covered by the mounting bracket 10, exposing at least a portion of each positioning groove 215 for the assembly and positioning of the mirror arm 23 of the rearview mirror 20.

[0063] The bracket assembly 100 is mounted on the vehicle window glass 300. Multiple solid adhesives 30 (such as 3M adhesive) are applied to the edge of the adhesive surface 2121 of the base 21. After applying the PU adhesive to the adhesive surface 2121 of the base 21 and the adhesion surface 12 of the mounting bracket 10, the base 21 and the mounting bracket 10 are mounted together on the inner glass surface 301 of the vehicle window glass 300. The cured PU adhesive forms an adhesive layer, which, together with the multiple solid adhesives 30, bonds and fixes the bracket assembly 100 to the vehicle window glass 300, enabling the bracket assembly 100 to withstand a large load. Furthermore, even under long-term heavy loads, the bonding reliability between the bracket assembly 100 and the vehicle window glass 300 is maintained, preventing delamination, gaps, or even the bracket assembly 100 falling off the vehicle window glass 300, thus improving driving safety. In this embodiment, the area of ​​the adhesive layer covering the adhesive surface 2121 is greater than or equal to 500 square millimeters (mm²). 2 This ensures that the base 21 and the window glass 300 have sufficient bonding area, thus guaranteeing the bonding strength and reliability of the base 21 and the window glass 300.

[0064] Since the PU adhesive requires a certain curing time, the solid adhesive 30 can play a certain pre-fixing role before the PU adhesive cures and forms an adhesive layer, preventing relative displacement between the bracket assembly 100 and the window glass 300, and ensuring assembly accuracy.

[0065] Multiple solid adhesives 30 are spaced apart from each other around the axis of the base 21, and are disposed on the outside of the adhesive layer and multiple protrusions 219 along the radial direction of the base 21. This ensures that air can pass through the gaps between the multiple solid adhesives 30 and come into contact with the PU adhesive. Water molecules in the air can undergo a cross-linking reaction with the PU adhesive, which can accelerate the curing speed of the PU adhesive to form an adhesive layer, thereby achieving reliable adhesion between the base 21 and the window glass 300.

[0066] PU adhesive is applied to the area enclosed by multiple solid adhesives 30. The multiple solid adhesives 30 also act as a barrier for the PU adhesive, reducing the amount of PU adhesive overflowing from the edge of the bonding surface 2121, ensuring sufficient adhesive between the bonding surface 2121 and the window glass 300, thereby ensuring the bonding strength between the base 21 and the window glass 300. In this embodiment, the number of solid adhesives 30 is preferably three.

[0067] Compared to adding metal ribs to the base 21 for sealing, this embodiment chooses solid adhesive 30 with elastic cushioning capacity as the sealing structure. On the one hand, it can reduce the risk of the metal ribs hitting the window glass 300 and causing the window glass 300 to break. On the other hand, it can provide cushioning when the base 21 and the window glass 300 collide, avoiding hard impact between the base 21 and the window glass 300 that would cause the window glass 300 to break.

[0068] In this embodiment, except for the adhesive surface 2121, the first surface 211, the connecting surface 2122, and the peripheral surface 213 of the base 21 all need to be treated with anodizing or electrophoretic painting to isolate air, improve the corrosion resistance and oxidation resistance of the base 21, and prevent the base 21 from rusting and affecting its appearance. The adhesive surface 2121 needs to be polished to increase its roughness, increase the effective contact area between the PU adhesive and the adhesive surface 2121, and thus improve the bonding reliability between the base 21 and the adhesive layer.

[0069] Before bonding the solid adhesive 30, a first primer area M1 is formed on the bonding surface 2121 of the base 21. A first primer (not shown) is applied to the first primer area M1 to enhance the adhesion of the solid adhesive 30 to the base 21, thereby making the subsequent bonding more reliable. For example, if the solid adhesive 30 is 3M adhesive, the first primer can be a 3M adhesive-specific tackifying primer, such as primer with model number 94#.

[0070] Before applying the adhesive layer, a second primer area M2 is provided on the adhesion surface 12 of the mounting bracket 10. A second primer (not shown) is applied to the second primer area M2 to enhance adhesion, thereby improving the bonding between the adhesive layer and the mounting bracket 10 after curing. For example, if the adhesive layer uses PU adhesive, the second primer can be a PU-specific tackifying primer, such as Dow Betaprime primer.

[0071] Before applying a primer to the base 21 and mounting bracket 10, a cleaning agent of model VP04604 can be used to clean the adhesion surface 12 and the bonding surface 2121, thereby improving the bonding reliability of the base 21 and mounting bracket 10 with the adhesive layer and primer.

[0072] Secondly, the isolation ribs 18 of the mounting bracket 10 can separate the 94# primer applied to the first primer area M1 and the Dow Betaprime primer applied to the second primer area M2, so as to avoid the overlapping of the primer application areas and affect the adhesion of the solid adhesive 30 and the adhesive layer.

[0073] It should be noted that this embodiment has the same structure as the first embodiment of the bracket assembly 100 described above, and will not be repeated here.

[0074] Please see Figure 10 , Figure 10 for Figure 3 A schematic diagram of the base structure of the fourth embodiment of the bracket assembly shown.

[0075] Unlike the third embodiment of the bracket assembly 100 described above, the structure of the base 21 in this embodiment is different. Specifically, the base 21 also includes multiple vent holes 220. These vent holes 220 penetrate the bonding surface 2121 and the first surface 211 of the base 21. The vent holes 220 allow air to pass through, enabling moisture in the air to fully contact the PU adhesive and accelerate the curing of the PU adhesive to form an adhesive layer. The vent holes 220 are spaced apart around the axis of the base 21, and are also spaced apart from the multiple protrusions 219. The vent holes 220 are positioned to avoid the multiple solid adhesives 30, ensuring reliable adhesion between the solid adhesives 30 and the base 21, and preventing the vent holes 220 from being blocked and unable to ventilate.

[0076] The number of vent holes 220 is greater than or equal to three to ensure the curing rate of the PU adhesive. In this embodiment, the number of vent holes 220 is three.

[0077] It should be noted that this embodiment has the same structure as the third embodiment of the bracket assembly 100 described above, and will not be repeated here.

[0078] Please see Figure 11 , Figure 11 for Figure 3 A schematic diagram of the base of the fifth embodiment of the bracket assembly shown.

[0079] Unlike the fourth embodiment of the bracket assembly 100 described above, the structure of the base 21 in this embodiment is different. Specifically, the base 21 may not require multiple solid adhesives 30 as a glue-blocking structure; instead, it may have multiple glue-retaining grooves 221 as a glue-concealing structure. The multiple glue-retaining grooves 221 are recessed into the bonding surface 2121 of the base 21 and are recessed towards the first surface 211. The multiple glue-retaining grooves 221 are spaced apart around the axis of the base 21. The multiple glue-retaining grooves 221 are located near the edge of the bonding surface 2121 and are spaced apart from each other by multiple vent holes 220 and multiple protrusions 219. The multiple glue-retaining grooves 221 are used to contain PU glue overflowing towards the edge of the bonding surface 2121, preventing glue from overflowing the bonding surface 2121. Furthermore, the multiple glue-retaining grooves 221 are filled with air, allowing the glue to contact the air inside the grooves after entering, further improving the curing efficiency of the PU glue. In this embodiment, the adhesive settling tank 221 can be an arc-shaped tank, and the number of adhesive settling tanks 221 is four.

[0080] Of course, in some embodiments, the adhesive sink 221 and the solid adhesive 30 can coexist on the base 21 and work together to prevent the PU adhesive from overflowing. Furthermore, it should be noted that this embodiment has the same structure as the fourth embodiment of the bracket assembly 100 described above, and will not be repeated here.

[0081] Please refer to the following: Figure 12 , Figure 13 and Figure 14 , Figure 12 for Figure 3 The diagram shows a partial structural design of the sixth embodiment of the support assembly. Figure 13 for Figure 12 The diagram shows a partial structural view of the bracket assembly from another angle. Figure 14 for Figure 13 The diagram shows the structure of the base of the bracket assembly.

[0082] Unlike the third embodiment of the bracket assembly 100 described above, the base 21 and the mounting bracket 10 in this embodiment have different structures.

[0083] Specifically, such as Figure 14As shown, the base 21 has a mounting groove 222, which is recessed into the peripheral side surface 213 of the base 21 and recessed towards the axial direction of the base 21. The mounting groove 222 penetrates the first surface 211 and the second surface 212 of the base 21. A positioning groove 215 is recessed into the side wall of the mounting groove 222, and the positioning groove 215 is recessed towards the axial direction of the base 21. In this embodiment, the mounting groove 222 is approximately an arc-shaped groove.

[0084] The base 21 also includes a glue-recessed groove 221. The glue-recessed groove 221 is recessed into the second surface 212 of the base 21 and is recessed towards the first surface 211. The glue-recessed groove 221 is filled with air, allowing the adhesive to contact the air inside when it enters, further improving the curing efficiency of the PU adhesive. In this embodiment, the glue-recessed groove 221 is approximately an annular groove, and the second surface 212 does not distinguish between the bonding surface 2121 and the connecting surface 2122 as in the third embodiment.

[0085] The base 21 also includes an injection molding groove 223. The injection molding groove 223 is recessed in the second surface 212 of the base 21 and protrudes towards the first surface 211 to form a limiting protrusion 224. The injection molding groove 223 is located at the edge of the base 21, that is, the limiting protrusion 224 is located at the edge of the base 21. Around the axial direction of the base 21, both the injection molding groove 223 and the limiting protrusion 224 are spaced apart from the assembly through groove 222. Along the radial direction of the base 21, both the injection molding groove 223 and the limiting protrusion 224 are spaced apart from the glue sink 221.

[0086] In this embodiment, the mounting bracket 10 is injection molded, and the base 21 is embedded in and fixed to the mounting bracket 10. Specifically, the base 21 is housed within the mounting through hole 17 of the mounting bracket 10, and a portion of the edge of the base 21 is embedded within the wall of the mounting through hole 17. At least a portion of the first surface 211 and the second surface 212 are exposed within the mounting through hole 17. The portion of the first surface 211 not exposed within the mounting through hole 17, the groove wall of the injection molding groove 223, and the raised surface of the limiting protrusion 224 are all covered by the mounting bracket 10. The base 21 and the mounting bracket 10 are limited and fixed by the injection molding groove 223 and the limiting protrusion 224. The assembly groove 222 of the base 21 communicates with the mounting through hole 17, and the groove sidewall of the assembly groove 222 is spaced apart from the wall of the mounting through hole 17, allowing air to pass through the gap between the groove sidewall of the assembly groove 222 and the wall of the mounting through hole 17 and come into contact with the PU adhesive, thereby accelerating the curing of the PU adhesive to form an adhesive layer.

[0087] like Figure 15 As shown, Figure 15 for Figure 12The diagram shows the structural structure of the bracket assembly. The lens arm 23 is mounted on the base 21 and positioned therewith via a positioning groove 215. The lens body 24 is mounted on the lens arm 23. A 94# primer is applied to the first base coating area M1 of the base 21, and solid adhesive 30 is applied to the first base coating area M1, ensuring good adhesion between the solid adhesive 30 and the base 21. By polishing the second surface 212 and applying Dow Betaprime primer to the second base coating area M2 of the mounting bracket 10, PU adhesive is applied to the second surface 212 and the adhesion surface 12 of the mounting bracket 10, covering the second base coating area M2, ensuring good adhesion between the PU adhesive and the base 21 and the mounting bracket 10.

[0088] The bracket assembly 100 is mounted on the vehicle window glass 300. Multiple solid adhesives 30 are pre-bonded to the inner glass surface 301 of the vehicle window glass 300. Multiple protrusions 219 of the base 21 support the inner glass surface 301 of the vehicle window glass 300, creating a gap between the second surface 212 and the inner glass surface 301. PU adhesive fills the gap between the second surface 212 and the inner glass surface 301, as well as the gap between the mounting bracket 10 and the vehicle window glass 300, and cures to form an adhesive layer. The adhesive layer bonds to the vehicle window glass 300, thus fixing the bracket assembly 100 relative to the vehicle window glass 300.

[0089] The base 21 is equipped with a glue sink 221. The PU glue enters the glue sink 221 and can come into contact with the air in the glue sink 221, which improves the curing rate. Moreover, the glue sink 221 can prevent the PU glue from overflowing, which can reduce the length of the solid glue 30 and the area of ​​the first base coating area M1 to a certain extent, thus saving costs.

[0090] It should be noted that this embodiment has the same structure as the third embodiment of the bracket assembly 100 described above, and will not be repeated here.

[0091] Please see Figure 16 , Figure 16 for Figure 3 A schematic diagram of a portion of the structure of the seventh embodiment of the support assembly shown.

[0092] Unlike the sixth embodiment of the bracket assembly 100 described above, the base 21 in this embodiment does not include protrusions 219, while the adhesive surface 12 of the mounting bracket 10 is provided with multiple supporting protrusions Q. When the bracket assembly 100 is mounted on the vehicle window glass 300, the multiple supporting protrusions Q of the mounting bracket 10 support the inner glass surface 301 of the vehicle window glass 300, so that a gap is formed between the adhesive surface 12 and the second surface 212 of the base 21 and the inner glass surface 301, and the PU adhesive can fully fill the gaps between the multiple supporting protrusions Q, and cure to form an adhesive layer in the gaps between the second surface 212 and the inner glass surface 301 and between the mounting bracket 10 and the vehicle window glass 300. The number of supporting protrusions Q is at least three to ensure the stability of the mounting bracket 10 supporting the vehicle window glass 300.

[0093] It should be noted that this embodiment has the same structure as the sixth embodiment of the bracket assembly 100 described above, and will not be repeated here. Of course, in some embodiments, when the base 21 is provided with protrusions 219, the mounting bracket 10 may also be provided with supporting protrusions Q to further ensure the filling effect of the adhesive layer between the base 21 and the window glass 300 and between the mounting bracket 10 and the window glass 300.

[0094] Please refer to the following: Figure 17 and Figure 18 , Figure 17 for Figure 3 The diagram shows a partial structure of the eighth embodiment of the support assembly. Figure 18 for Figure 17 The diagram shows a partial structural view of the support assembly from another angle. Among them, Figure 17 and Figure 18 The rearview mirror arm and mirror body of the bracket assembly are not shown; only the assembly relationship between the base and the mounting bracket is shown.

[0095] Unlike the sixth embodiment of the bracket assembly 100 described above, the base 21 and mounting bracket 10 in this embodiment have slightly different structures. The base 21 includes multiple vent holes 220, and the mounting bracket 10 has multiple through holes 19. Each through hole 19 is coaxially arranged with and communicates with a vent hole 220 to allow air to pass through.

[0096] Specifically, the multiple through holes 19 of the mounting bracket 10 all penetrate the adhesion surface 12 and the mounting surface 11 of the mounting bracket 10, and the multiple through holes 19 are arranged around the edge of the mounting through hole 17 and spaced apart from the edge of the mounting through hole 17. In this embodiment, the number of through holes 19 is three.

[0097] Multiple vent holes 220 of the base 21 penetrate the first surface 211 and the second surface 212 of the base 21. The multiple vent holes 220 are spaced apart along the axis of the base 21 and are arranged together around the adhesive settling groove 221. The multiple vent holes 220 are staggered from the first primer area M1 of the base 21 to ensure the reliability of the adhesion between the solid adhesive 30 and the base 21, and also to prevent the vent holes 220 from being blocked by the solid adhesive 30 and unable to ventilate. In this embodiment, the number of vent holes 220 is the same as the number of through holes 19, which is also three.

[0098] In this embodiment, by providing a through hole 19 on the mounting bracket 10 and a vent hole 220 on the base 21, the vent hole 220 and the through hole 19 cooperate to allow air to smoothly enter the adhesive side of the base 21 from the adhesive side of the mounting bracket 10 through the through hole 19 and the vent hole 220, so as to fully contact the PU adhesive and accelerate the curing speed of the PU adhesive to form an adhesive layer.

[0099] It should be noted that the same structure as the sixth embodiment described above is used in this embodiment and will not be repeated here.

[0100] In related technologies, as the level of automotive intelligence continues to increase, the number of various electronic components such as in-vehicle cameras, radars, and antennas is constantly increasing. These electronic components are mostly mounted on the windshield using independent brackets. However, the limited space inside the vehicle makes it difficult to meet the independent installation needs of multiple types of electronic components. To save interior space, there are existing integrated structures that integrate in-vehicle electronic components into the rearview mirror arm. However, this integrated structure increases the load on the rearview mirror base. Conventional rearview mirror bases are mostly fixed to the windshield using solid adhesives (such as 3M adhesive). With the increased weight of the rearview mirror assembly, long-term load can easily cause the adhesive between the base and the windshield to fail, resulting in gaps. In severe cases, it can even cause the windshield to crack or break, posing a significant driving safety hazard.

[0101] In this embodiment, compared to the prior art where the rearview mirror and electronic components are installed separately, the bracket assembly 100 of this embodiment integrates the rearview mirror 20, the information acquisition element, and the mounting bracket 10 into one unit. The mounting bracket 10 is injection molded and covers at least part of the outer side of the base 21, so that the base 21 of the rearview mirror 20 can be fixedly connected to the mounting bracket 10. Even if the weight of the rearview mirror 20 increases, causing an increase in the load on the base 21, or if the information acquisition element is integrated into the rearview mirror 20, causing an increase in the load on the base 21, the mounting bracket 10 can help the base 21 distribute the load, avoiding problems such as adhesion failure, delamination, and gaps caused by the base 21 being bonded separately to the window glass 300. It also avoids the risk of cracking or breakage of the window glass 300 due to the stress concentration of the adhesive between the base 21 and the window glass 300, thus improving driving safety.

[0102] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
