Abstract

This application relates to a guide bracket, a door glass assembly, and a door assembly. The guide bracket includes: a base with an adhesive surface; and a sliding engagement portion for tightly sliding with a door sealing strip, the sliding engagement portion being connected to the base. The base is made of a first material, and the sliding engagement portion is made of a second material. The surface energy of the first material is greater than that of the second material, and the coefficient of sliding friction between the sliding engagement portion and the door sealing strip is less than that between the base and the door sealing strip. The relatively high surface energy of the first material and the relatively low surface energy of the second material allow for better adhesive strength after the base is bonded to the door glass with adhesive, and also result in lower sliding friction between the sliding engagement portion and the door sealing strip. This helps to mitigate the problem of significant wear between the guide bracket and the door sealing strip.

Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a guide bracket, a door glass assembly, and a door assembly. Background Technology

[0002] The widely used flush-mounted door glass assemblies have guide brackets at both the front and rear ends of the door glass. These guide brackets engage with the door sealing strip on the door sheet metal guide rail. The tight sliding contact between the guide brackets and the door sealing strip effectively guides the vertical movement of the door glass. Furthermore, during vehicle operation, the close contact between the guide brackets and the door sealing strip helps stabilize the door glass, preventing it from shaking due to airflow.

[0003] In the related technology, after a long period of use, the guide bracket and the door sealing strip of the car door glass assembly are prone to significant wear, which can lead to gaps between the guide bracket and the door sealing strip, causing the car door glass to wobble when sliding up and down. Summary of the Invention

[0004] Based on this, a guide bracket, a door glass assembly, and a door assembly are provided to improve the problem of significant wear between the guide bracket and the door sealing strip.

[0005] An embodiment of the first aspect of this application provides a guide bracket, the guide bracket comprising: a base having an adhesive surface for bonding with a vehicle door glass; and a sliding engagement portion for tightly sliding with a vehicle door sealing strip, the sliding engagement portion being connected to the base; wherein the base is made of a first material, the sliding engagement portion is made of a second material, the surface energy of the first material is greater than the surface energy of the second material, and the coefficient of sliding friction between the sliding engagement portion and the vehicle door sealing strip is less than the coefficient of sliding friction between the base and the vehicle door sealing strip.

[0006] The guide bracket in this embodiment has an adhesive surface at its base for bonding with the door glass, and a sliding engagement portion for tightly sliding with the door sealing strip. The surface energy of the first material of the base is greater than that of the second material of the sliding engagement portion; that is, the surface energy of the first material is relatively large, and the surface energy of the second material is relatively small. This allows for better adhesive strength after the base is bonded to the door glass with adhesive, and also results in lower sliding friction between the sliding engagement portion and the door sealing strip. This helps to mitigate the problem of significant wear between the guide bracket and the door sealing strip. Furthermore, the coefficient of sliding friction between the sliding engagement portion and the door sealing strip is lower than that between the base and the door sealing strip. This further reduces the sliding friction between the sliding engagement portion and the door sealing strip, thereby further mitigating the problem of wear between the guide bracket and the door sealing strip.

The sliding mating portion is also provided with a third positioning portion and a fourth positioning portion, both of which are used to tightly abut against the door sealing strip to restrict the guide bracket from moving relative to the door sealing strip along a second direction. The second direction is parallel to the thickness direction of the door glass.

[0010] In some embodiments, the first positioning portion is a first arched structure that protrudes in a direction away from the door glass; the sliding mating portion is provided with a first hollow portion located near the first arched structure, the first hollow portion being used to provide space for the first arched structure to elastically deform.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

[0048] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0049] In related technologies, flush-mounted door glass assemblies feature guide brackets at both the front and rear ends of the door glass. These guide brackets engage with door sealing strips on the door sheet metal guide rails. The tight sliding cooperation between the guide brackets and the door sealing strips effectively guides the vertical movement of the door glass. Furthermore, during vehicle operation, the close cooperation between the guide brackets and the door sealing strips effectively stabilizes the door glass, preventing it from vibrating due to airflow.

[0050] After prolonged use, significant wear can occur between the guide bracket and the door seal, resulting in gaps between them and causing the door glass to wobble when sliding up and down.

[0051] To address the aforementioned issues, the first aspect of this application proposes a guide bracket designed to improve the problem of significant wear between the guide bracket and the door sealing strip.

[0052] like Figures 1 to 7 As shown, the guide bracket 100 in the first aspect embodiment of this application includes a base 110 and a sliding engagement portion 120. The base 110 is provided with an adhesive surface 111 for bonding with the door glass 200. The sliding engagement portion 120 is used for tight sliding engagement with the door sealing strip 20 and is connected to the base 110. The base 110 is made of a first material, and the sliding engagement portion 120 is made of a second material. The surface energy of the first material is greater than that of the second material, and the coefficient of sliding friction between the sliding engagement portion 120 and the door sealing strip 20 is less than the coefficient of sliding friction between the base 110 and the door sealing strip 20.

[0053] Specifically, materials with different surface energies exhibit different properties. For materials with higher surface energies, the adhesive can fully wet the material surface, resulting in a stronger bond between the material and the adhesive. For materials with lower surface energies, their self-cleaning properties, drag-reducing and friction-reducing properties, and anti-fouling properties are relatively better.

[0054] In this embodiment of the application, the guide bracket 100 has a base 110 with an adhesive surface 111 for bonding with the door glass 200, and a sliding engagement portion 120 for tightly sliding engagement with the door sealing strip 20. The surface energy of the first material of the base 110 is greater than the surface energy of the second material of the sliding engagement portion 120, that is, the surface energy of the first material is relatively large and the surface energy of the second material is relatively small. This allows the base 110 to have good adhesive strength after being bonded to the door glass 200 with adhesive, and allows the sliding engagement portion 120 and the door sealing strip 20 to have small sliding friction, thereby helping to improve the problem of large wear easily occurring between the guide bracket 100 and the door sealing strip 20. In addition, the coefficient of sliding friction between the sliding mating part 120 and the door sealing strip 20 is less than the coefficient of sliding friction between the base 110 and the door sealing strip 20. As a result, the sliding friction between the sliding mating part 120 and the door sealing strip 20 can be further reduced, thereby further improving the problem of easy wear between the guide bracket 100 and the door sealing strip 20.

[0055] In some embodiments, the second material is POM (polyoxymethylene) or POM with added glass fiber. Both POM and POM with added glass fiber have self-lubricating properties. Using this material as the material of the sliding mating part 120 is beneficial to further reduce the sliding friction between the sliding mating part 120 and the door sealing strip 20, thereby further improving the problem of easy wear between the guide bracket 100 and the door sealing strip 20.

[0056] In some embodiments, the first material is a composition of PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer), or PA6 (polyamide 6), or PA6 with added glass fibers, or PBT (polybutylene terephthalate), or PBT with added glass fibers, or PP (polypropylene). These materials have high surface energy, and when used as the material for the base 110, good bonding strength can be obtained when the base 110 is bonded to the door glass 200 with adhesive.

[0057] Furthermore, the sliding mating part 120 and the base 110 can be combined together by two-material injection molding, or the sliding mating part 120 and the base 110 can be manufactured separately and then connected together by snap-fit, screw fastening or other methods.

[0058] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the sliding mating part 120 is provided with a first positioning part 121 and a second positioning part 122. Both the first positioning part 121 and the second positioning part 122 are used to tightly abut against the door sealing strip 20 to restrict the guide bracket 100 from moving relative to the door sealing strip 20 along a first direction. The first direction is parallel to the plane where the door glass 200 is located and perpendicular to the length direction of the guide bracket 100. The sliding mating part 120 is also provided with a third positioning part 123 and a fourth positioning part 124. Both the third positioning part 123 and the fourth positioning part 124 are used to tightly abut against the door sealing strip 20 to restrict the guide bracket 100 from moving relative to the door sealing strip 20 along a second direction. The second direction is parallel to the thickness direction of the door glass 200.

[0059] In this embodiment, the first positioning part 121 and the second positioning part 122 limit the guide bracket 100 from moving freely relative to the door sealing strip 20 in the first direction. The third positioning part 123 and the fourth positioning part 124 also limit the guide bracket 100 from moving freely relative to the door sealing strip 20 in the second direction. This arrangement ensures a stable fit between the guide bracket 100 and the door sealing strip 20, thereby improving the stability of the door glass 200 and preventing it from shaking due to airflow.

[0060] In one embodiment, the first positioning part 121 is a first arched structure that protrudes in a direction away from the door glass 200, and the sliding mating part 120 is provided with a first hollow part 125 that is close to the first arched structure. The first hollow part 125 is used to provide space for the first arched structure to elastically deform.

[0061] In this embodiment, using a first arched structure as the first positioning part 121 reduces the contact area between the first positioning part 121 and the door sealing strip 20, which helps to avoid excessive sliding friction between the guide bracket 100 and the door sealing strip 20. Furthermore, the sliding mating part 120 is also provided with a first hollow part 125 near the first arched structure. The first hollow part 125 provides space for elastic deformation of the first arched structure, meaning that the first arched structure can undergo elastic deformation. Based on this, the first arched structure can undergo a certain degree of elastic deformation, thereby allowing an interference fit between the guide bracket 100 and the door sealing strip 20. This helps to avoid gaps in the first direction between the guide bracket 100 and the door sealing strip 20, which could lead to poor fit. In summary, the structure in this embodiment helps to ensure that the sliding friction between the guide bracket 100 and the door sealing strip 20 is neither too large nor too small. This ensures good stability of the door glass 200 during its up-and-down sliding, thus preventing the door glass 200 from shaking, and also helps to prevent damage to the door sealing strip 20 due to excessive friction during the up-and-down sliding process.

[0062] Furthermore, based on the elastic deformation capability of the first positioning part 121, the second positioning part 122 is a rigid structure that protrudes towards the door glass 200.

[0063] For example, the second positioning part 122 can be a solid block structure 122a protruding toward the door glass 200 (see reference). Figure 4 Alternatively, it can be a second arched structure 122b that protrudes towards the door glass 200 (please refer to...). Figure 5 Based on this, a second hollow part 126 may be provided on the sliding fit part 120 near the second arch structure 122b. A support column 127 for supporting the second arch structure 122b may be provided in the second hollow part 126 to enhance the strength and rigidity of the second arch structure 122b.

[0064] The second positioning part 122 is a protruding rigid structure, which helps to reduce the contact area between the second positioning part 122 and the door sealing strip 20, thereby helping to avoid excessive sliding friction between the guide bracket 100 and the door sealing strip 20. In addition, for the flush door glass 200, it has a long side and a short side. The end with the long side is preferably the guide bracket 100 in this embodiment. Based on the rigid structure of the second positioning part 122, the second positioning part 122 can serve as the installation reference for the door glass 200. When there is an installation deviation in the guide bracket 100 or a torque generated due to thermal expansion and contraction, it helps to reduce the offset of the short side of the door glass 200, thereby helping to avoid the problem of water leakage inside the vehicle caused by a gap between the door glass 200 and the body sealing strip due to a large offset.

[0065] It is understandable that the second positioning part 122 and the first positioning part 121 have opposite bulging or protruding directions, but the protruding directions of both are parallel to the first direction.

[0066] In some embodiments, such as Figure 8 As shown, the top of the first arched structure and / or the second arched structure 122b is provided with a protrusion 129. This arrangement facilitates the installation, positioning, and inspection of the guide bracket 100 during the assembly of the door assembly 1.

[0067] Furthermore, the protrusion 129 can be a square protrusion with a height of no more than 1 mm and an area of ​​no more than 5 mm * 5 mm, which helps to reduce the sliding friction between the square protrusion and the door sealing strip 20.

[0068] Furthermore, such as Figure 3 As shown, the number of first positioning parts 121 can be multiple (e.g., two, three, or four), and these multiple first positioning parts 121 can be spaced apart. The number of second positioning parts 122 is equal to the number of first positioning parts 121, and the second positioning parts 122 and first positioning parts 121 can be arranged in pairs. For example, the second positioning parts 122 located on the upper part of the guide bracket 100 and the second positioning parts 122 located on the lower part of the guide bracket 100 can adopt different structures. For instance, the second positioning part 122 located on the upper part of the guide bracket 100 is a solid block structure 122a, and the second positioning part 122 located on the lower part of the guide bracket 100 is a second arched structure 122b. The upper solid block structure 122a can better restrict the position of the door glass 200, while the lower second arched structure 122b helps to appropriately reduce the assembly stress caused by assembly errors.

[0069] In one embodiment, such as Figure 3 , Figure 4As shown, the third positioning part 123 is a third arched structure that protrudes in a direction away from the door glass 200. The sliding fit part 120 is provided with a third hollow part 128 that is close to the third arched structure. The third hollow part 128 is used to provide space for the elastic deformation of the third arched structure.

[0070] In this embodiment, using a third arched structure as the third positioning part 123 reduces the contact area between the third positioning part 123 and the door sealing strip 20, which helps to avoid excessive sliding friction between the guide bracket 100 and the door sealing strip 20. Furthermore, the sliding fit part 120 also has a third hollow part 128 near the third arched structure. The third hollow part 128 provides space for elastic deformation of the third arched structure, meaning that the third arched structure can undergo elastic deformation. Based on this, the third arched structure can undergo a certain degree of elastic deformation, thereby achieving an interference fit between the guide bracket 100 and the door sealing strip 20. This helps to avoid gaps between the guide bracket 100 and the door sealing strip 20 in the second direction, which could lead to poor fit. In summary, the structure in this embodiment helps to ensure that the sliding friction between the guide bracket 100 and the door sealing strip 20 is neither too large nor too small. This ensures good stability of the door glass 200 during its up-and-down sliding, thus preventing the door glass 200 from shaking, and also helps to prevent damage to the door sealing strip 20 due to excessive friction during the up-and-down sliding process.

[0071] Furthermore, the fourth positioning part 124 can be a positioning plane disposed on the sliding fit part 120 and perpendicular to the second direction.

[0072] Furthermore, the number of third positioning units 123 can be multiple (e.g., two, three, or four), and the multiple third positioning units 123 can be arranged at intervals. The number of fourth positioning units 124 is equal to the number of third positioning units 123, and the fourth positioning units 124 and the third positioning units 123 can be arranged in pairs.

[0073] In some embodiments, a protrusion 129 is provided at the top of the third arch structure. This arrangement facilitates the installation, positioning, and inspection of the guide bracket 100 during the assembly of the door assembly 1.

[0074] Furthermore, the protrusion 129 can be a square protrusion with a height of no more than 1 mm and an area of ​​no more than 5 mm * 5 mm, which helps to reduce the sliding friction between the square protrusion and the door sealing strip 20.

[0075] In some embodiments, such as Figure 9 , Figure 10As shown, the bonding surface 111 is provided with a plurality of spaced protrusions 112, which are used to abut against the door glass 200. The protrusions 112 ensure that there is point contact between the guide bracket 100 and the door glass 200. In addition, an adhesive layer is provided between the bonding surface 111 and the door glass 200. The thickness of the adhesive layer compensates for the manufacturing tolerances between the guide bracket 100 and the door glass 200. This arrangement helps to reduce the assembly error between the guide bracket 100 and the door glass 200.

[0076] Furthermore, the adhesive layer can be cured from two types of adhesives. One type is a quick-drying adhesive, which can play a pre-fixing role after the guide bracket 100 is positioned. The other type is a common PU adhesive, which has good bonding strength.

[0077] Furthermore, the height of the boss 112 is greater than or equal to 0.6 mm and less than or equal to 2.0 mm to ensure the thickness of the adhesive layer between the bonding surface 111 and the door glass 200.

[0078] like Figure 1 As shown, an embodiment of the second aspect of this application provides a door glass assembly 10, which includes a door glass 200, a first guide bracket 100a, and a second guide bracket 100b. The door glass 200 has a first end and a second end disposed opposite to each other along the vehicle's driving direction. The first guide bracket 100a is disposed at the first end of the door glass 200, and the second guide bracket 100b is disposed at the second end of the door glass 200. At least one of the first guide bracket 100a and the second guide bracket 100b is the guide bracket 100 in any embodiment of the first aspect described above.

[0079] The door glass assembly 10 in this embodiment includes a guide bracket 100 comprising a base 110 and a sliding engagement portion 120. The base 110 is provided with an adhesive surface 111 for bonding with the door glass 200. The sliding engagement portion 120 is used for tight sliding engagement with the door sealing strip 20. The surface energy of the first material of the base 110 is greater than the surface energy of the second material of the sliding engagement portion 120, that is, the surface energy of the first material is relatively large and the surface energy of the second material is relatively small. This allows the base 110 to have good adhesive strength after being bonded to the door glass 200 with adhesive, and allows the sliding engagement portion 120 to have small sliding friction with the door sealing strip 20, thereby helping to improve the problem of large wear easily occurring between the guide bracket 100 and the door sealing strip 20. In addition, the coefficient of sliding friction between the sliding mating part 120 and the door sealing strip 20 is less than the coefficient of sliding friction between the base 110 and the door sealing strip 20. As a result, the sliding friction between the sliding mating part 120 and the door sealing strip 20 can be further reduced, thereby further improving the problem of easy wear between the guide bracket 100 and the door sealing strip 20.

[0080] like Figure 11 As shown, an embodiment of the third aspect of this application provides a door assembly 1, which includes the door glass assembly 10 of any of the embodiments of the second aspect described above. The door assembly 1 also includes a door (not shown in the figure), a door sealing strip 20, and a lifting mechanism. The door sealing strip 20 is disposed on the door, and a sliding engagement portion 120 is tightly slidably engaged with the door sealing strip 20. The lifting mechanism is mounted on the door and connected to the door glass 200 for driving the door glass 200 to rise and fall relative to the door.

[0081] The door assembly 1 in this application embodiment is based on the same inventive concept as the door glass assembly 10 in the second aspect embodiment above, and therefore has all the beneficial effects of the door glass assembly 10 above.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
