Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a vehicle and a support structure and a glass mechanism thereof. Background Art

[0002] With the advancement of the wave of automobile intelligence, cars with autonomous driving technology have become common. In order to achieve the autonomous driving of the vehicle, it is necessary to install a front windshield bracket on the inside of the front glass near the roof and equip the front windshield bracket with a camera.

[0003] The common installation scheme for the windshield bracket on existing vehicles is usually to assemble the windshield bracket and the glass by PU gluing. Before PU gluing, the front windshield bracket needs to be coated with M300 primer at the bonding position. When gluing, it is necessary to ensure that the primer on the front windshield bracket and the glass end is completely dry.

[0004] like Figure 1 As shown, however, after the primer is cured, solidified crystals 102 will be formed on the surface of the front windshield support 101. When the solidified crystals 102 come into contact with the glass 200, they will form a pointed stress-concentrated surface, which can easily cause problems such as cracking of the glass 200, and further lead to a low yield rate of the glass structure formed by the installation of the front windshield support 101 and the glass 200.

[0005] Therefore, it is necessary to propose a support structure to solve at least one of the above problems. Utility Model Content

[0006] In view of the defects existing in the prior art, the embodiments of the present invention provide a vehicle and its support structure, and a glass structure, which can ensure uniform glue thickness while solving the problem of glass cracking caused by local stress concentration after the primer is cured, thereby greatly improving the yield rate of the glass structure.

[0007] The specific technical solution of the implementation mode of the utility model is:

[0008] A support structure comprises: a support body, wherein the support body has a first surface facing the glass and a second surface opposite to the first surface in the thickness direction; a plurality of boss structures are distributed on the first surface and at intervals in the peripheral area of ​​the support body, and the boss structures are used to contact the surface of the glass.

[0009] In a preferred embodiment, the heights of the plurality of boss structures are consistent.

[0010] In a preferred embodiment, a rubber-blocking rib is provided on the first surface and around the outer contour edge of the bracket body, and the height of the rubber-blocking rib is lower than the height of the boss structure.

[0011] In a preferred embodiment, a gap of 0.2 mm to 0.5 mm is formed between the rubber retaining rib and the surface of the glass.

[0012] In a preferred embodiment, the gap formed between the glue blocking rib and the surface of the glass is 0.3 mm.

[0013] In a preferred embodiment, a predetermined gluing track is provided on the first surface, and the boss structures are distributed around the gluing track.

[0014] In a preferred embodiment, a gap of at least 3 mm is formed between the boss structure and the gluing track.

[0015] In a preferred embodiment, a first area is provided on the first surface, the first area is used to arrange electrical components with position accuracy requirements, and at least part of the boss structure is arranged in the first area.

[0016] In a preferred embodiment, a second area is arranged on the first surface, a printed heating line is arranged in the second area, and the boss structure does not overlap with the second area.

[0017] In a preferred embodiment, the boss structure is integrally formed with the bracket body.

[0018] In a preferred embodiment, the spacing distance between two adjacent boss structures is greater than 60 mm.

[0019] In a preferred embodiment, the boss structure has a contact plane in contact with the surface of the glass, and the area of ​​the contact plane is 1 square millimeter to 2 square millimeters.

[0020] A glass structure comprises any of the above-mentioned support structures and glass, wherein a primer layer and an adhesive layer are arranged between the glass and the support structure.

[0021] In a preferred embodiment, the glass mechanism includes any one of the following: a front windshield mechanism, a rear windshield mechanism, and a sunroof glass mechanism.

[0022] A vehicle comprises any of the glass mechanisms described above.

[0023] The technical solution of the utility model has the following significant beneficial effects:

[0024] In the embodiment of the present application, a plurality of boss structures are distributed at intervals in the peripheral area on the first surface of the support body and the glass, and after the boss structure is in direct contact with the glass surface, the boss structure can effectively support the glass, and the boss structure can be used to form a certain thickness spacing between the first surface of the support body and the glass, and the thickness spacing can be used to set the primer and the adhesive layer. Since the height of the boss structure is consistent, it can be ensured that the thickness spacing can be controlled to be a uniform spacing, and then the thickness of the primer and the adhesive layer can be ensured to be uniform. Among them, since the thickness of the primer is thin, much smaller than the thickness of the adhesive layer, when the thickness spacing between the first surface of the support body and the glass is a uniform spacing, it is equivalent to ensuring the uniform thickness of the adhesive layer, which can avoid the problem of the adhesive thickness being too thin due to excessive pressing when the support is bonded. At the same time, since the primer does not directly contact the glass, but contacts the glass using the boss structure, it can overcome the problem of glass cracking caused by local stress concentration after the primer is cured in the prior art, thereby greatly improving the yield rate of the glass structure.

[0045] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] like Figure 1 As shown, in the prior art, the surface of the bracket is usually in direct contact with the glass, and the gap between the bracket surface and the glass cannot be guaranteed to be uniform during the pressing process, which can easily lead to uneven glue thickness and also easily cause problems such as glass cracking, which in turn will lead to a low yield rate of the glass mechanism formed by the installation of the front windshield bracket and the glass.

[0049] The utility model provides a vehicle and a support structure thereof, and a glass mechanism, which can ensure uniform glue thickness while solving the problem of glass cracking caused by local stress concentration after primer curing, and can effectively improve the yield rate of the glass mechanism.

[0050] Please refer to Figure 2 and Figure 3 In the embodiment of the present application specification, a support structure 100 is provided, and the support structure 100 may include: a support body 1 which is in the shape of a plate as a whole, and the support body 1 has a first surface 11 facing the glass 200 and a second surface 12 opposite to the first surface 11 in the thickness direction; a plurality of boss structures 2 are distributed on the first surface 11 and at intervals in the peripheral area of ​​the support body 1, and the boss structures 2 are used to contact the surface of the glass 200. The heights of the plurality of boss structures 2 are consistent. The consistency of the heights of the plurality of boss structures 2 means that the heights are the same or similar within the allowable manufacturing and processing error range.

[0051] In the embodiment of the present application, a plurality of boss structures 2 are distributed at intervals in the peripheral area on the bracket body 1 and the first surface 11 facing the glass 200. After the boss structure 2 is in direct contact with the surface of the glass 200, the boss structure 2 can effectively support the glass 200, and the boss structure 2 can be used to form a certain thickness spacing between the first surface 11 of the bracket body 1 and the glass 200. The thickness spacing can be used to set the primer 4 and the adhesive layer 5. Since the height of the boss structure 2 is consistent, it can be ensured that the thickness spacing can be controlled to be a uniform spacing, and then the thickness of the primer 4 and the adhesive layer 5 can be ensured to be uniform. Among them, since the thickness of the primer 4 is relatively thin, much smaller than the thickness of the adhesive layer 5, when the thickness spacing between the first surface 11 of the bracket body 1 and the glass 200 is a uniform spacing, it is equivalent to ensuring that the thickness of the adhesive layer 5 is uniform, which can avoid the problem of excessive pressure on the bracket during bonding, resulting in too thin glue. At the same time, since the base coating 4 does not directly contact the glass 200, but contacts the glass 200 via the boss structure 2, the problem of glass 200 cracking caused by local stress concentration after the base coating is cured in the prior art can be overcome, thereby greatly improving the yield rate of the glass structure.

[0052] In some embodiments, a rubber-blocking rib 3 is disposed on the first surface 11 and around the outer contour edge of the bracket body 1 , and the height of the rubber-blocking rib 3 is lower than the boss structure 2 .

[0053] In this embodiment, on the first surface 11, a glue blocking rib 3 is arranged around the outer contour edge of the bracket body 1, and the glue blocking rib 3 can be used to block the glue to prevent the glue from overflowing from between the bracket body 1 and the glass 200 when they are pressed and bonded.

[0054] The height of the adhesive stop rib 3 is lower than the boss structure 2, which can prevent the adhesive stop rib 3 from directly contacting the glass 200. In particular, the adhesive stop rib 3 may be brushed with the primer 4. When the height of the adhesive stop rib 3 is lower than the boss structure 2, the primer solidified crystal structure on the adhesive stop rib 3 can be prevented from contacting the glass 200, thereby preventing the adhesive stop rib 3 from causing the glass 200 to crack.

[0055] In one embodiment, a gap of 0.2 mm to 0.5 mm is formed between the rubber blocking rib 3 and the surface of the glass 200 .

[0056] The gap between the glue blocking rib 3 and the surface of the glass 200 is not too large or too small. If it is too large, for example, greater than 0.5 mm, the glue blocking rib 3 cannot reliably guarantee the glue blocking function; if it is too small, for example, less than 0.2 mm, the glue blocking rib 3 will have the risk of contacting the glass 200 due to the inevitable errors in manufacturing and installation. Preferably, the gap formed between the glue blocking rib 3 and the surface of the glass 200 is 0.3 mm. When the gap between the glue blocking rib 3 and the surface of the glass 200 is reasonably controlled at about 0.3 mm, on the one hand, the glue blocking function of the glue blocking rib 3 itself can be reliably guaranteed, and on the other hand, the glue blocking rib 3 can be prevented from contacting the surface of the glass 200.

[0057] In some embodiments, a predetermined gluing track is provided on the first surface 11 , and the boss structures 2 are distributed around the gluing track.

[0058] In this embodiment, since the support structure 100 and the glass 200 are fixed mainly by bonding, when bonding the support structure 100 and the glass 200, it is necessary to bond the support structure 100 to a predetermined position on the first surface 11, such as Figure 2 As shown, multiple glue tracks are provided. The boss structures 2 are distributed around the glue tracks, so that reliable support can be provided for the glass 200 here, preventing the gap between the glass 200 and the support structure 100 from being too small due to the setting of the glue position, resulting in insufficient glue thickness.

[0059] In a specific embodiment, a gap of at least 3 mm is formed between the boss structure 2 and the glue track. When the gap between the boss structure 2 and the glue track reaches more than 3 mm, it can be prevented that the primer is brushed onto the boss structure 2, thereby causing the crystal on the surface of the boss structure 2 to crack the glass 200 after solidification.

[0060] In some embodiments, the boss structure 2 is integrally formed with the bracket body 1. Specifically, the bracket body 1 and the boss structure 2 can be integrally formed by injection molding. When the bracket body 1 and the boss structure 2 are integrally formed, on the one hand, the boss structure 2 can be accurately positioned relative to the bracket body 1, and on the other hand, since the two are integrally formed, they have significant advantages in terms of firmness of fit and manufacturing cost.

[0061] Of course, the specific setting method of the boss structure 2 can also be other methods, not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0062] In some embodiments, the spacing distance between two adjacent boss structures 2 is greater than 60 mm.

[0063] In this embodiment, the boss structure 2 can be distributed along the peripheral area of ​​the support body 1 at intervals. Considering that the support structure 100 and the glass 200 are fitted together, the whole is a curved surface. When the support structure 100 is integrally formed, there may be some distortion. In order to prevent the boss structure 2 on the integrally formed support structure 100 from being able to achieve an ideal fit with the glass 200, the interval between two adjacent boss structures 2 should not be too small, and can be controlled to be greater than 60 mm.

[0064] like Figure 2 As shown, in some embodiments, a first area is provided on the first surface 11, and the first area is used to provide electrical components with position accuracy requirements, and at least part of the boss structure 2 is provided in the first area.

[0065] In this embodiment, the boss structure 2 can be evenly arranged in the peripheral area of ​​the bracket body 1 and the installation area of ​​electrical device accessories (such as ADAS cameras) with high position requirements to ensure that the position does not sag, resulting in angle deviation and affecting the road information collection. Taking the ADAS camera installation area as an example, a camera installation hole is provided on the bracket body 1. The first area can be the camera hole 6 and the trapezoidal area connected to the camera hole 6.

[0066] Of course, it is not excluded that other areas with specific functions need to be set on the first surface 11 of the bracket body 1. The areas with specific functions also have higher positioning requirements, or other requirements that require the setting of the boss structure 2. The function of the above-mentioned first area is only an example. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0067] In some other embodiments, a second area is provided on the first surface 11, and a printed heating line is provided in the second area, and the boss structure 2 does not overlap with the second area. The second area provided with the printed heating line may specifically be an area corresponding to the surface of the camera hole 6 (not shown in the figure).

[0068] In this embodiment, the boss structure 2 can be arranged away from the printed heating line, so as to avoid affecting the normal function of the printed heating line.

[0069] In the embodiment of the present application, the boss structure 2 has a contact plane in contact with the surface of the glass 200 , and the area of ​​the contact plane is 1 square millimeter to 2 square millimeters.

[0070] In the embodiment of the present application, the boss structure 2 can contact the glass 200 and play the role of supporting the bracket structure 100. It can ensure the uniform thickness of the adhesive layer 5 (PU glue) while reducing the cracks of the glass 200 caused by local stress concentration after the primer is cured, thereby meeting the bonding requirements.

[0071] Specifically, the boss structure 2 can be spherical, for example, the two ends are planarized on the basis of the spherical shape, wherein the lower plane contacts the bracket body 1, and the upper plane contacts the glass 200. The contact plane in contact with the glass 200 can have an area of ​​1 square millimeter to 2 square millimeters to avoid crushing and cracking of the glass 200 due to sharp point contact.

[0072] Of course, the specific structure of the boss structure 2 can also be other structural forms, such as a conical cone, etc., and is not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0073] A glass mechanism is also provided in an embodiment of the present application, and the glass mechanism includes the above-mentioned support structure 100. The glass mechanism can achieve the technical effect achieved by the implementation of the support structure 100 by setting the support structure 100. For details, please refer to the specific description of the above-mentioned implementation, and the present application will not repeat them here.

[0074] The glass structure, in addition to the support structure 100 , further comprises glass 200 , and a primer layer 4 and an adhesive layer 5 are provided between the glass 200 and the support structure 100 .

[0075] Wherein, the glass mechanism may include any one of the following: a front windshield mechanism, a rear windshield mechanism, and a sunroof glass mechanism. Of course, the glass mechanism may also be arranged at other locations where there is demand and space for installation.

[0076] A vehicle is also provided in an embodiment of the present application, and the vehicle includes the above-mentioned glass mechanism. The vehicle can achieve the technical effect achieved by the glass mechanism embodiment by setting the glass mechanism. For details, please refer to the specific description of the above-mentioned embodiment, and the present application will not repeat them here.

There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0078] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0079] The above are only a few embodiments of the present invention.
