Meanwhile, in the running process of the vehicle, the guide bracket is tightly matched with the vehicle door sealing strip, so that the vehicle door glass can be well stabilized, and the shaking caused by the action of air flow on the vehicle door glass is avoided.
After long-time use, the guide bracket and the door sealing strip are easy to generate larger abrasion, so that a gap is formed between the guide bracket and the door sealing strip, and the door glass can shake when sliding up and down.
In view of the foregoing, an embodiment of the first aspect of the present application proposes a guide bracket, which aims to improve the problem that a large abrasion is likely to occur between the guide bracket and a door weather strip.
As shown in fig. 1 to 7, the guide bracket 100 in the first aspect of the embodiment of the present application includes a base portion 110 and a slide fit portion 120, the base portion 110 is provided with an adhesive surface 111 for adhering to the door glass 200, the slide fit portion 120 is for a close sliding fit with the door weather strip 20, and the slide fit portion 120 is connected to the base portion 110. Wherein the base 110 is made of a first material, the sliding fit portion 120 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 sliding friction coefficient between the sliding fit portion 120 and the door weather strip 20 is smaller than the sliding friction coefficient between the base 110 and the door weather strip 20.
In particular, materials with different surface energies have a number of different properties, and for materials with a larger surface energy, the glue can sufficiently wet the surface of the material, which results in a greater bond strength of the material together with the glue. For materials with smaller surface energy, the self-cleaning performance, the resistance and friction reduction performance, the anti-staining performance and the like of the materials are relatively good.
In the guide bracket 100 according to the embodiment of the present application, the base 110 is provided with the bonding surface 111 for bonding with the door glass 200, the sliding fit portion 120 is used for tightly sliding fit 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 fit portion 120, that is, the surface energy of the first material is relatively greater, and the surface energy of the second material is relatively smaller, so that the base 110 can have better bonding strength after bonding with the door glass 200 through glue, and smaller sliding friction force can be provided between the sliding fit portion 120 and the door sealing strip 20, thereby being beneficial to improving the problem that larger abrasion is easy to occur between the guide bracket 100 and the door sealing strip 20. In addition, the sliding friction coefficient between the sliding fit portion 120 and the door weather strip 20 is smaller than the sliding friction coefficient between the base portion 110 and the door weather strip 20, whereby the sliding friction force between the sliding fit portion 120 and the door weather strip 20 can be further reduced, and the problem of the easy wear between the guide bracket 100 and the door weather strip 20 can be further improved.
In some embodiments, the second material is POM (polyoxymethylene) or POM with glass fibers added. Both the POM and the POM added with the glass fiber have self-lubricating properties, and the material is used as the material of the sliding fit portion 120, which is beneficial to further reducing the sliding friction force between the sliding fit portion 120 and the door weather strip 20, thereby further improving the problem that abrasion is easy to occur between the guide bracket 100 and the door weather strip 20.
In some embodiments, the first material is a combination of PC (polycarbonate) and ABS (referring to acrylonitrile-butadiene-styrene copolymer), or PA6 (polyamide 6), or PA6 with glass fibers added, or PBT (polybutylene terephthalate), or PBT with glass fibers added, or PP (polypropylene). The material has a large surface energy, and when the material is used as the material of the base 110, the base 110 can obtain a good bonding strength after being bonded with the door glass 200 by glue.
Further, the sliding fit portion 120 and the base portion 110 may be combined together by two-material injection molding, or the sliding fit portion 120 and the base portion 110 may be connected together by clamping, screw locking, or the like after being manufactured and molded.
In some embodiments, as shown in fig. 3, 4, 5, 6 and 7, the sliding fit portion 120 is provided with a first positioning portion 121 and a second positioning portion 122, where the first positioning portion 121 and the second positioning portion 122 are used to tightly abut against the door weather strip 20, so as to limit the movement of the guide bracket 100 relative to the door weather strip 20 along a first direction, the first direction is parallel to a plane where the door glass 200 is located, and the first direction is perpendicular to a length direction of the guide bracket 100. The sliding fit portion 120 is further provided with a third positioning portion 123 and a fourth positioning portion 124, where the third positioning portion 123 and the fourth positioning portion 124 are used to tightly abut against the door weather strip 20 to limit the movement of the guide bracket 100 relative to the door weather strip 20 in a second direction parallel to the thickness direction of the door glass 200.
In this embodiment, the guide bracket 100 is made not freely movable in the first direction with respect to the door weather strip 20 by the stopper action of the first and second positioning portions 121 and 122, and the guide bracket 100 is made not freely movable in the second direction with respect to the door weather strip 20 by the stopper action of the third and fourth positioning portions 123 and 124. By the arrangement, the guide bracket 100 and the door sealing strip 20 can keep stable matching relation, so that the stability of the door glass 200 is improved, and the door glass 200 is prevented from shaking due to the action of air flow.
In one embodiment, the first positioning portion 121 is a first arch structure protruding away from the door glass 200, and the sliding fit portion 120 is provided with a first hollow portion 125 disposed near the first arch structure, where the first hollow portion 125 is used to provide an elastically deformed space for the first arch structure.
In this embodiment, the first arch structure is used as the first positioning portion 121, so that the contact area between the first positioning portion 121 and the door weather strip 20 can be reduced, which is beneficial to avoiding the situation that the sliding friction force between the guide bracket 100 and the door weather strip 20 is too large. In addition, the sliding fit portion 120 is further provided with a first hollowed portion 125 at a position close to the first arch structure, and the first hollowed portion 125 provides an elastic deformation space for the first arch structure, that is, the first arch structure can be elastically deformed, on the basis, the first arch structure can be elastically deformed to a certain extent, so that the guide bracket 100 and the door sealing strip 20 are in interference fit, and in this way, the problem that poor fit between the guide bracket 100 and the door sealing strip 20 is caused due to a gap generated between the guide bracket 100 and the door sealing strip 20 in the first direction is avoided. In summary, the structure in this embodiment is beneficial to ensuring that the sliding friction force between the guide bracket 100 and the door sealing strip 20 is not too large or too small, so that good stability in the vertical sliding process of the door glass 200 can be ensured, and thus the door glass 200 is prevented from shaking, and damage to the door sealing strip 20 caused by too large friction force in the vertical sliding process can be avoided.
Further, the second positioning portion 122 has a rigid structure protruding in a direction approaching the door glass 200, on the basis that the first positioning portion 121 has elastic deformability.
For example, the second positioning portion 122 may be a solid block structure 122a protruding toward the direction approaching the door glass 200 (please refer to fig. 4), or may be a second arch structure 122b protruding toward the direction approaching the door glass 200 (please refer to fig. 5), on this basis, the sliding fit portion 120 may be provided with a second hollowed out portion 126 disposed near the second arch structure 122b, and the second hollowed out portion 126 may be provided therein with a strut 127 for supporting the second arch structure 122b to enhance the strength and rigidity of the second arch structure 122b.
The second positioning portion 122 is a protruding rigid structure, which is beneficial to reducing the contact area between the second positioning portion 122 and the door seal strip 20, so as to avoid the situation of excessive sliding friction between the guide bracket 100 and the door seal strip 20. In addition, for the flush door glass 200, the long side and the short side are provided, one end of the long side is preferably selected as the guide bracket 100 in the embodiment of the application, and on the basis that the second positioning portion 122 adopts a rigid structure, the second positioning portion 122 can be used as a mounting reference of the door glass 200, when the guide bracket 100 has mounting deviation or generates moment due to expansion caused by heat and contraction caused by cold, the offset of the short side of the door glass 200 is reduced, so that the problem of water leakage in a vehicle caused by a gap between the vehicle body sealing strip and the door glass 200 due to larger offset is avoided.
It will be appreciated that the second positioning portion 122 and the first positioning portion 121 have opposite bulging directions or protruding directions, but both protruding directions are parallel to the first direction.
In some embodiments, as shown in fig. 8, the top of the first arch and/or the second arch 122b is provided with a bump 129. So configured, it is convenient to install, locate and detect the guide bracket 100 during assembly of the door assembly 1.
Further, the bump 129 may be a square bump, where the height of the square bump is not greater than 1mm, and the area of the square bump is not greater than 5mm by 5mm, so as to reduce the sliding friction between the square bump and the door seal 20.
Further, as shown in fig. 3, the number of the first positioning portions 121 may be plural (for example, two, three, four, etc.), and the plural first positioning portions 121 may be disposed at intervals. The number of the second positioning portions 122 is equal to that of the first positioning portions 121, and the second positioning portions 122 and the first positioning portions 121 may be provided in pairs. Illustratively, the second positioning part 122 located at the upper portion of the guide bracket 100 and the second positioning part 122 located at the lower portion of the guide bracket 100 may take different structures. For example, the second positioning portion 122 located at the upper portion of the guide bracket 100 is a solid block-shaped structure 122a, and the second positioning portion 122 located at the lower portion of the guide bracket 100 is a second arch-shaped structure 122b. Wherein the upper solid block structure 122a can better limit the position of the door glass 200, and the lower second arch structure 122b is advantageous for properly reducing the assembly stress generated by the assembly error.
In one embodiment, as shown in fig. 3 and 4, the third positioning portion 123 is a third arch structure protruding away from the door glass 200, and the sliding fit portion 120 is provided with a third hollow portion 128 disposed near the third arch structure, where the third hollow portion 128 is used for providing an elastically deformed space for the third arch structure.
In this embodiment, the third arch structure is used as the third positioning portion 123, so that the contact area between the third positioning portion 123 and the door weather strip 20 can be reduced, which is beneficial to avoiding the situation that the sliding friction force between the guide bracket 100 and the door weather strip 20 is too large. In addition, the sliding fit portion 120 is further provided with a third hollow portion 128 at a position close to the third arch structure, and the third hollow portion 128 provides an elastically deformed space for the third arch structure, that is, the third arch structure can be elastically deformed, on the basis, the third arch structure can be elastically deformed to a certain extent, so that the guide bracket 100 and the door sealing strip 20 are in interference fit, and in this way, the problem that poor fit between the guide bracket 100 and the door sealing strip 20 is caused due to a gap generated between the guide bracket 100 and the door sealing strip 20 in the second direction is avoided. In summary, the structure in this embodiment is beneficial to ensuring that the sliding friction force between the guide bracket 100 and the door sealing strip 20 is not too large or too small, so that good stability in the vertical sliding process of the door glass 200 can be ensured, and thus the door glass 200 is prevented from shaking, and damage to the door sealing strip 20 caused by too large friction force in the vertical sliding process can be avoided.
Further, the fourth positioning portion 124 may be a positioning plane disposed on the sliding fit portion 120 and perpendicular to the second direction.
Further, the number of the third positioning portions 123 may be plural (for example, two, three, four, etc.), and the plural third positioning portions 123 may be disposed at intervals. The number of the fourth positioning portions 124 is equal to the number of the third positioning portions 123, and the fourth positioning portions 124 and the third positioning portions 123 may be provided in pairs.
In some embodiments, the top of the third arch is provided with a bump 129. So configured, it is convenient to install, locate and detect the guide bracket 100 during assembly of the door assembly 1.
Further, the bump 129 may be a square bump, where the height of the square bump is not greater than 1mm, and the area of the square bump is not greater than 5mm by 5mm, so as to reduce the sliding friction between the square bump and the door seal 20.
In some embodiments, as shown in fig. 9 and 10, a plurality of bosses 112 are disposed on the bonding surface 111 at intervals, and the bosses 112 are used to abut against the door glass 200. The boss 112 is provided to make the guide bracket 100 and the door glass 200 in point contact, and in addition, a glue layer is provided between the bonding surface 111 and the door glass 200, and the thickness of the glue layer compensates for the production tolerance between the guide bracket 100 and the door glass 200, so that the installation error between the guide bracket 100 and the door glass 200 is reduced.
Further, the glue layer may be formed by solidifying two glue layers, wherein one glue layer is a quick-drying glue, and can play a pre-fixing role after the positioning of the guide bracket 100, and the other glue layer is a common PU glue, which has a better bonding strength.
Further, the height of the boss 112 is greater than or equal to 0.6mm and less than or equal to 2.0mm to ensure the thickness of the adhesive layer between the adhesive surface 111 and the door glass 200.

In addition, the sliding friction coefficient between the sliding fit portion 120 and the door weather strip 20 is smaller than the sliding friction coefficient between the base portion 110 and the door weather strip 20, whereby the sliding friction force between the sliding fit portion 120 and the door weather strip 20 can be further reduced, and the problem of the easy wear between the guide bracket 100 and the door weather strip 20 can be further improved.
As shown in fig. 11, an embodiment of the third aspect of the present application proposes a door assembly 1 including a door glass assembly 10 in any of the embodiments of the second aspect described above. The door assembly 1 further includes a door (not shown), a door weather strip 20, and a lifter mechanism. The door weather strip 20 is provided at the door, the sliding fit portion 120 is in close sliding fit with the door weather strip 20, the lifting mechanism is mounted at the door, and the lifting mechanism is connected with the door glass 200 for driving the door glass 200 to lift relative to the door.
The door assembly 1 according to the embodiment of the present application is in the same inventive concept as the door glass assembly 10 according to the second embodiment described above, and therefore has all the advantageous effects that the door glass assembly 10 described above has.
