[0002] With the widespread use of brackets on glass, especially the use of metal brackets such as the base of the rearview mirror and the fixed bracket in the sunroof on automobile glass, in order to improve the stability of the bracket, it is generally necessary to bond the bracket to the glass with polyurethane glue.

[0003] In the related art, in order to ensure that the polyurethane glue has a certain bonding thickness, a plurality of convex structures are generally provided on the bottom surface of the bracket to abut the glass surface, so as to ensure that there is enough polyurethane glue to fill the gap between the bottom surface of the bracket and the glass surface.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0034] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element.

[0035] Considering that when existing brackets are bonded to glass surfaces, in order to ensure that the polyurethane glue has a certain bonding thickness, a plurality of convex structures are generally provided on the bottom surface of the bracket to abut the glass surface to ensure that there is sufficient polyurethane glue filling gap between the bottom surface of the bracket and the glass surface. However, the polyurethane glue around the aforementioned convex structures will expand and contract due to the influence of the ambient temperature, resulting in local tension inside the glass at the contact position between the convex structure and the glass, and then there is a risk of glass cracking. Therefore, the convex structure provided in the related art has the problem of difficulty in taking into account the problem of having sufficient polyurethane glue filling gap between the bottom surface of the bracket and the glass surface to ensure the bonding effect and prevent the glass from cracking. The present application provides a bonding limit device and a bracket, which, on the one hand, can ensure that the polyurethane glue can have a sufficient filling thickness to ensure the bonding effect, and on the other hand, there is no risk of glass cracking, which is convenient for application and promotion.

[0036] Specifically, please refer to Figure 1 、 Figure 2 and Figure 5 One embodiment of the present application provides an adhesive limiting device 10, which may have a first adhesive surface 100 and a second adhesive surface 200 disposed opposite to each other. The first adhesive surface 100 is configured to abut against the connection surface of the mounting member 20, and the second adhesive surface 200 is configured to abut against the connection surface of the target member 2. The adhesive limiting device 10 also includes through-holes 300 intermittently disposed through the first adhesive surface 100 and the second adhesive surface 200. The through-holes 300 are configured to be filled with adhesive 500.

[0037] The bonding limiter 10, by virtue of its configuration of a first bonding surface 100 and a second bonding surface 200, is capable of forming surface contact with the connection surface of the target component 2 via the second bonding surface 200, thereby avoiding the risk of generating splinter stress at the location of the bump structure, as in conventional techniques where a bump structure is provided on the mounting member 20. Furthermore, the bonding limiter 10 of the present application is provided with through-holes 300 intermittently extending through the first bonding surface 100 and the second bonding surface 200, allowing the adhesive 500 to be filled into the through-holes 300, thereby ensuring that the adhesive 500 has a sufficient filling thickness and improving the bonding effect.

[0038] It is understandable that the perforation 300 has a filling depth, which is determined by the thickness of the adhesive limiting device 10. Therefore, it is only necessary to configure the adhesive limiting device 10 to be the same thickness as the adhesive 500 to be filled to ensure the filling thickness of the adhesive 500 in the perforation 300.

[0039] It is worth noting that when the first bonding surface 100 abuts the connection surface of the mounting member 20, or when the second bonding surface 200 abuts the connection surface of the target member 2, the side wall of the through hole 300 and the connection surface of one of the two can form a filling position for filling the adhesive 500, and the adhesive 500 will be kept in the hole position and will not overflow under the limiting effect of the connection surface of one of the two and the side wall. Therefore, the above-mentioned bonding limiting device 10 of the present application also has a certain material blocking and limiting effect, which can prevent the adhesive 500 from overflowing during filling and bonding, thereby improving the concentration of the adhesive 500 and further improving the bonding effect.

[0040] Optionally, the aforementioned mounting part 20 can be configured as, but is not limited to, a bracket, such as the base of a car's interior rearview mirror or a fixed bracket inside a sunroof, such as a fixed bracket inside a sunroof for fixing an in-car camera to the sunroof; the aforementioned target part 2 can be configured as, but is not limited to, a glass part or a sheet metal part, such as the curved glass of a car.

[0041] Optionally, the adhesive 500 may be, but is not limited to, polyurethane adhesive or the like.

[0042] Continue reading Figure 1 The perforation 300 may be, but is not limited to, configured as a square. Of course, in other embodiments, the perforation 300 may also be configured as a circle or a triangle.

[0043] Optionally, combined Figure 1 and Figure 2 As shown, the perforations 300 can be evenly distributed along the surface of the first bonding surface 100 and / or the second bonding surface 200, so as to improve the consistency of the bonding area of ​​the adhesive 500 on each perforation 300, thereby ensuring that the adhesive 500 in each perforation 300 has sufficient bonding effect.

[0044] Preferably, each through-hole 300 may be set to have the same filling depth to maintain consistency in the thickness of the adhesive 500 filled in each through-hole 300 .

[0045] Optionally, two adjacent through-holes 300 are spaced apart from each other by a limiting structure 400, and the limiting structure 400 is provided with an air vent 410 penetrating to the two adjacent through-holes 300, thereby promoting full contact between the adhesive 500 and the air, accelerating the curing of the adhesive 500, and improving the bonding effect.

[0046] It is worth noting that the adhesive limiting device 10 of the present application is provided with a through hole 300 that passes through the first adhesive surface 100 and the second adhesive surface 200. Thus, when the through hole 300 is filled with adhesive 500, the adhesive limiting device 10 can maintain a stable adhesive effect with the mounting member 20 through the adhesive 500 filled in the through hole 300. Then, the adhesive limiting device 10 can be kept separate from the mounting member 20 before being bonded to the target member 2. Specifically, Figure 4 and Figure 5 As shown, when the mounting part 20 needs to be bonded to the target part 2, the separately set bonding limit device 10 can be bonded to the target part 2 first, and then the adhesive 500 is filled into the through hole 300, and finally the connecting surface of the mounting part 20 is pressed against the first bonding surface 100 of the bonding limit device 10.

[0047] It is understood that the above bonding steps can be applied when the connection surface of the target part 2 is facing horizontally upward or slightly tilted. For example, when the connection surface of the target part 2 is facing horizontally upward, when the bonding stopper 10 is bonded to the target part 2 and the adhesive 500 is filled into the through-hole 300, the adhesive 500 will not overflow. In this case, it is only necessary to press the connection surface of the mounting member 20 from top to bottom against the first bonding surface 100 of the bonding stopper 10.

[0048] In other embodiments, the limiting structure 400 may be provided with a first adhesive layer on the side of the first adhesive surface 100, and the first adhesive layer is used to adhere to the connection surface of the mounting member 20 to maintain a stable connection between the bonding limiting device 10 and the mounting member 20. Specifically, this embodiment is suitable for scenarios where the connection surface of the target member 2 is horizontally facing downward, such as a sunroof of a car.

[0049] For example, in a scenario where the connection surface of target part 2 is facing horizontally downward, when mounting part 20 needs to be bonded to target part 2, the bonding stopper 10 can be bonded to mounting part 20 first, and then adhesive 500 can be filled into through-hole 300. It is worth noting that at this point, the connection surface of mounting part 20 is raised horizontally upward. This way, when adhesive 500 is filled into through-hole 300, it will not overflow due to the material blocking effect of stopper structure 400. Finally, the connection surface of mounting part 20 is simply pressed from bottom to top against the horizontal connection surface of target part 2, completing the secure bonding between mounting part 20 and target part 2.

[0050] Preferably, the limiting structure 400 is provided with a second adhesive layer on the side of the second adhesive surface 200. The second adhesive layer is used to bond with the connection surface of the target part 2. This ensures that the adhesive limiting device 10 can be maintained in its bonding position before the adhesive 500 filled into the through-hole 300 solidifies, preventing the adhesive limiting device 10 from shifting and improving the bonding accuracy. It is understandable that this embodiment can be applied to the aforementioned scenario when the connection surface of the target part 2 is horizontally facing upward, that is, the adhesive limiting device 10 can first be bonded to the connection surface of the target part 2 via the second adhesive layer to maintain its position, and then the adhesive 500 can be filled into the through-hole 300.

[0051] Optionally, the first adhesive layer and the second adhesive layer may be implemented as, but not limited to, self-adhesive adhesives, such as solid double-sided tape.

[0052] Optionally, the first bonding surface 100 can be configured as a shape that can fit with the connecting surface of the mounting member 20. For example, the connecting surface of the mounting member 20 can be a plane or a curved surface. Adaptively, the first bonding surface 100 can be configured as a plane or a curved surface that can fit with the connecting surface of the mounting member 20. This helps to improve the degree of fit between the bonding limit device 10 and the mounting member 20, and then helps to improve the connection effect between the bonding limit device 10 and the mounting member 20. It also helps to reduce or avoid the bonding gap when the bonding limit device 10 and the mounting member 20 are connected, and then reduce or avoid overflow when the adhesive 500 is filled into the perforation 300.

[0053] Optionally, the second bonding surface 200 can be configured into a shape that can fit with the connecting surface of the target part 2. For example, the connecting surface of the target part 2 can be a plane or a curved surface. Adaptively, the first bonding surface 100 can be configured into a plane or a curved surface that can fit with the connecting surface of the mounting part 20. This helps to improve the degree of fit between the bonding limit device 10 and the target part 2, and then helps to improve the connection effect between the bonding limit device 10 and the target part 2. It also helps to reduce or avoid the bonding gap when the bonding limit device 10 is connected to the target part 2, and then reduce or avoid overflow when the adhesive 500 is filled into the perforation 300.

[0054] In some embodiments, the bonding and limiting device 10 can be made of a deformable material, so that the first bonding surface 100 and the second bonding surface 200 can be deformed to adapt to the shape of the connection surface of the mounting member 20, thereby improving the degree of fit between the bonding and limiting device 10 and the mounting member 20, and thus helping to improve the connection effect between the bonding and limiting device 10 and the target part 2. For example, the connection surface of the target part 2 can be designed as a curved surface, and the bonding and limiting device 10 is made of a deformable material so that the second bonding surface 200 of the bonding and limiting device 10 can be designed as a flat surface rather than conforming to the shape of the connection surface of the target part 2. In this way, when the second bonding surface 200 is attached to the connection surface of the target part 2, it can be deformed by extrusion into a curved surface that can fit the connection surface of the target part 2, which helps to reduce the manufacturing cost of the bonding and limiting device 10.

[0055] It is worth noting that according to the above-mentioned embodiments of the present application, the use of deformable material in the bonding limit device 10 also helps to make the bonding limit device 10 have a certain degree of compressibility, which can then absorb the shape surface difference between the mounting part 20 and the target part 2, thereby improving the fit between the mounting part 20 and the target part 2.

[0056] For example, the target part 2 can be configured as a curved glass. When the mounting member 20 needs to be bonded to the curved glass, the connecting surface of the mounting member 20 is generally configured to be a curved surface that is compatible with the curved glass. The connecting surface of the mounting member 20 may have a shape difference with the curved glass due to production precision. According to the above embodiment of the present application, by using a deformable material for the bonding limiter 10, the bonding limiter 10 has a certain degree of compressibility, which enables the bonding limiter 10 to press against and deform the bonding limiter 10, thereby eliminating the shape difference between the connecting surface of the mounting member 20 and the curved glass, thereby improving the fit between the mounting member 20 and the curved glass.

[0057] Optionally, the deformable material may be, but is not limited to, configured as an elastic rubber material or a polyurethane foam material, so that soft contact between the bonding limit device 10 and the mounting part 20 and the target part 2 can be achieved.

[0058] Optionally, the bonding limit device 10 can be configured to be cuttable so that the bonding limit device 10 can be cut to a shape consistent with the connecting surface of the first bonding surface 100 and the mounting member 20 , which helps to improve the versatility of the bonding limit device 10 .

[0059] For example, combined Figure 2 and Figure 3 As shown, when the adhesive limiting device 10 of the present application is used to connect mounting parts 20 with connecting surfaces of different shapes, the adhesive limiting device 10 can be cut to the same shape as the aforementioned connecting surface, which helps to improve the versatility of the adhesive limiting device 10.

[0060] like Figure 2 As shown, the connection surface of the mounting member 20 is a square. Adaptively, the bonding limiter 10 can be cut so that its first bonding surface 100 is also the same square.

[0061] like Figure 3 As shown, the connecting surface of the mounting member 20 is circular. Adaptively, the bonding limit device 10 can be cut so that its first bonding surface 100 is also the same circle. In this way, shape adaptation between the bonding limit device 10 and the connecting surface of the mounting member 20 can be achieved, thereby improving the versatility of the bonding limit device 10.

[0062] More specifically, when the bonding limit device 10 of the present application is in use, an bonding limit device 10 having an area larger than the connecting surface of the mounting member 20 can be used. In this way, the bonding limit device 10 can be completely covered and bonded to the connecting surface of the mounting member 20 first, and then the excess part of the bonding limit device 10 protruding from the connecting surface of the mounting member 20 can be cut off to achieve shape adaptation between the bonding limit device 10 and the mounting member 20, thereby avoiding the need for the first bonding surface 100 of the bonding limit device 10 to be aligning and fitting the shape with the connecting surface of the mounting member 20, thereby reducing the difficulty of operation.

[0063] Of course, in some other embodiments, the bonding limit device 10 can also be pre-cut to the same shape as the connecting surface of its first bonding surface 100 and the mounting member 20, and then the first bonding surface 100 and the connecting surface of the mounting member 20 are aligned and bonded to each other.

[0064] Combine Figure 2 and Figure 3 As shown, according to another aspect of the present application, the present application further provides a mounting bracket 1, which includes the above-mentioned adhesive limiting device 10. The mounting bracket 1 also includes a mounting member 20, and the mounting member 20 has a first connecting surface 21. The first adhesive surface 100 of the adhesive limiting device 10 and the first connecting surface 21 are fixed to each other.

[0065] The mounting bracket 1 described above has a first bonding surface 100 and a second bonding surface 200 provided by the bonding stopper 10, so that the bonding stopper 10 can form surface contact with the connection surface of the target part 2 through the second bonding surface 200, thereby avoiding the risk of generating splinter stress at the location of the bump structure when a bump structure is provided on the mounting part 20 as in conventional technology. In addition, the bonding stopper 10 of the mounting bracket 1 described above in the present application is provided with through-holes 300 that pass through the first bonding surface 100 and the second bonding surface 200 at intervals, so that the adhesive 500 can be filled into the through-holes 300, ensuring that the adhesive 500 has a sufficient filling thickness, thereby improving the bonding effect.

[0066] Combine Figure 4and Figure 5 As shown, according to another aspect of the present application, a glass assembly is provided, comprising the aforementioned mounting bracket 1. The glass assembly further comprises a glass component. It is noteworthy that in this embodiment, the aforementioned target component 2 is configured as a glass component of the glass assembly. The glass component has a second connecting surface 201. The second bonding surface 200 of the bonding and limiting device 10 abuts against the second connecting surface 201. The through-hole 300 of the bonding and limiting device 10 is filled with adhesive 500.

[0067] Optionally, the glass assembly may be configured as, but not limited to, a sunroof, a windshield, or a side window of a car.

[0068] In the aforementioned glass assembly, the second bonding surface 200 of the adhesive stopper 10 abuts against the second connecting surface 201 to form surface contact. This avoids the risk of splinter stress generated at the bump structure location, as in conventional techniques, when a bump structure is provided on the mounting member 20. Furthermore, the aforementioned glass assembly ensures a sufficient filling thickness of the adhesive 500 by filling the through-hole 300, thereby improving the bonding effect.

[0069] Alternatively, the first connecting surface 21 can be flat, and the second connecting surface 201 of the glass piece can be curved. The first bonding surface 100 is configured as a flat surface that can be bonded to the first connecting surface 21, and the second bonding surface 200 is configured as a curved surface that can be bonded to the second connecting surface 201. This can improve the compatibility between the bonding stopper 10 and the mounting member 20, and between the bonding stopper 10 and the glass piece. It is understood that in this embodiment, the glass piece is configured as curved glass, and the curved glass has the second connecting surface 201 configured as a curved surface as described above.

[0070] Alternatively, in other embodiments, the bonding and limiting device 10 is made of a deformable material, and the first bonding surface 100 and the second bonding surface 200 are configured to be deformable to mate with the first and second connecting surfaces, respectively. Therefore, the second bonding surface 200 of the bonding and limiting device 10 can be designed as a flat surface rather than a curved surface that conforms to the second connecting surface 201 of the glass component. Furthermore, when the second bonding surface 200 is bonded to the second connecting surface 201 of the glass component, it can be deformed by compression to a curved surface that mates with the second connecting surface 201. This helps reduce the manufacturing cost of the glass assembly.

[0071] Optionally, the two adjacent perforations 300 of the bonding limit device 10 are spaced apart from each other by a limiting structure 400, and the limiting structure 400 is provided with a first bonding layer on the first bonding surface 100 side, and the first bonding layer is bonded to the first connecting surface 21, and the limiting structure 400 is provided with a second bonding layer on the second bonding surface 200 side, and the second bonding layer is bonded to the second connecting surface 201, which helps to achieve a quick fixed connection between the mounting part 20 and the bonding limit device 10, and between the bonding limit device 10 and the glass part.

[0072] Optionally, the limiting structure 400 is provided with an air hole 410 that passes through two adjacent perforations 300, and both the perforations 300 and the air hole 410 are filled with adhesive 500, which helps to improve the filling adequacy of the adhesive 500 between each perforation 300, thereby improving the installation stability of the mounting bracket 1 on the glass component.

[0073] Optionally, the adhesive 500 can be configured as PU (Polyurethane) adhesive, and the first adhesive layer and the second adhesive layer can be configured as solid double-sided adhesive. The solid double-sided adhesive can help to achieve rapid installation and positioning between the mounting part 20 and the adhesive limiting device 10, and between the adhesive limiting device 10 and the glass part. However, the PU adhesive requires a certain curing time. Therefore, the PU adhesive is used in conjunction with the solid double-sided adhesive. The solid double-sided adhesive is first used to position the adhesive limiting device 10 and the mounting part 20 or the glass part, and then the PU adhesive is filled. This helps to improve the ease of operation of filling the adhesive 500.

[0074] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
