Description

Technical Field

[0001] (Cross - reference to related applications) This application claims priority to a Chinese patent application with patent application number 202210859255.8, filing date July 21, 2022, and invention title "Bracket Structure, Frameless Vehicle Door and Vehicle".

[0002] The present invention relates to the field of vehicles, and particularly to a bracket structure, a frameless vehicle door, and a vehicle.

Background Art

[0003] As consumers' demands for fashion, sports, and individuality increase, frameless vehicle doors are more widely applied to vehicles (such as coupes, etc.), and not only are the process requirements for the strips, rails, and lifting mechanisms of frameless vehicle doors becoming higher, but the up - and - down movement of the glass should be automatically controlled each time the door is opened and closed.

[0004] The design of a frameless vehicle door is different from that of a general vehicle door. The fact that it can be closely attached to the vehicle body means that a door opening and closing system is arranged on the frameless vehicle door. When the vehicle door is opened, the glass is automatically lowered a little, and after the vehicle door is closed, the glass automatically rises and is locked to the sealing strip mounted on the vehicle body. Therefore, there is no need to worry about the sealing problem of the frameless vehicle door. However, the glass of the frameless vehicle door should guarantee an accurate opening and closing position during the up - and - down movement of the window. Without the guidance of a frame, such a problem becomes more important.

Summary of the Invention

Problems to be Solved by the Invention

[0005] At the current stage, the glass of the frameless vehicle door is supported by brackets, which are mostly made of metal steel structures (aluminum alloy materials). When the glass is mounted on the brackets (specifically, when adhering the metal brackets and the glass, first tape is attached to the corresponding position of the glass, and then gel is injected from the gel injection port and cured), the angle and mounting relationship formed between the brackets and the glass cannot be changed. Subsequently, the brackets are clamped or tightened again with the connection structure on the elevator to complete the mounting. However, when the window of the vehicle is fixed to the elevator, it is difficult to correct the exact position of the window. Therefore, the main problems existing during the mounting of the frameless vehicle door and the glass in existing vehicles are mainly as follows. That is, 1. The hardness of the metal bracket structure is high. First, tape is adhered to the bottom to prevent the glass from directly contacting the metal bracket. However, the addition of the tape adhesion process makes the operation steps cumbersome and the mounting difficult. 2. During the process of applying the gel, paper tape (to protect the glass surface) and rubber strips (functioning to prevent the intrusion of the gel) are attached around the brackets, and then all areas of the rubber strips are sealed with transparent tape. After that, the rubber strips on both sides are fixed with paper tape to ensure the sealing performance. However, it takes about 30 minutes to complete the whole process. This method consumes a long time and affects the mounting efficiency. 3. The following two methods are used as existing gel curing methods. The first is to naturally dry the gel (for about 40 to 50 minutes), and when it is not completely cured, remove all the paper tapes and rubber strips around the bracket, and then perform processes such as gel cleaning and adjustment of the conformity tolerance by an inspection tool. However, it takes about 1 hour to completely cure. The second is to dry with a heater gun. First, heat for about 3 to 5 minutes to observe the state of the gel. When it is not completely cured, remove all the paper tapes and rubber strips around the bracket, and then perform processes such as gel cleaning and adjustment of the conformity tolerance by an inspection tool, and then heat and cure for 3 to 5 minutes on the table. In the above two methods, since the two-component gel becomes quite hard after curing, it is necessary to clean the gel in a state where the bracket is semi-cured. At this time, the bracket should be removed from the working device. However, because the bracket is in a semi-cured state, an offset occurs at the position between the glass and the bracket, and it must be positioned by an inspection tool. In short, the natural curing time is long and the heat curing operation is complicated. 4. When adhering the glass and the bracket, they are all loosely combined (that is, a gap of 1-3 mm is generated between the glass surface and the inner wall of the bracket groove). Due to this mounting method, the glass does not receive the action of preloading, and it is impossible to guarantee a stable movement trajectory during the lifting and lowering of the glass. Furthermore, when the glass rises to the highest position, it is impossible to guarantee a good combination effect with the seal strip. 5. Due to the characteristics of the metal bracket structure and the combination of the bracket groove and the glass with a gap, there is no adjustment space after the glass is mounted and cured. Therefore, if the glass does not strictly control the conformity tolerance in terms of size (for example, the tolerance of the glass conformity is ±0.5), a smooth mounting cannot be guaranteed.

[0006] Therefore, there are problems such as difficulty in mounting, long consumption time, and low matching effect when combining the glass and the bracket.

[0007] The object of the present invention is to provide a bracket structure, a frameless vehicle door, and a vehicle that can finely adjust the offset of glass by means of a bracket, reduce the matching degree requirements of the frameless vehicle door with respect to the glass itself, and increase the production rate.

[0008] Another object of the present invention is to provide a bracket structure, a frameless vehicle door, and a vehicle that can improve the mounting efficiency and reduce the human power consumption by omitting complicated operations such as sticking tape to the bracket during the glass mounting process.

Means for Solving the Problems

[0009] In order to achieve the above object, the present invention provides a bracket structure for supporting and positioning the glass of a vehicle window. The bracket structure includes a support member and an adjustment member. The support member is provided with a first support wall and a second support wall facing each other, and a support groove is formed between the first support wall and the second support wall. The bottom of the glass is provided in the support groove. The adjustment member is connected to the first support wall, and the adjustment member has a deformation amount towards the glass and presses the first support wall to apply pressure to the glass, so that the top of the glass is adhered to the seal strip on the vehicle body.

[0010] The present invention provides a frameless vehicle door including the glass and the bracket structure. The bottom of the glass is provided in the bracket structure, and the bracket structure applies pressure to the glass so that the top of the glass and the seal strip on the vehicle body are locked.

[0011] The present invention provides a vehicle including the above frameless vehicle door.

Effects of the Invention

[0012] The bracket structure finely adjusts the offset of the glass, locks it to the seal strip on the vehicle body when the glass rises to the highest position, ensures the joint between the glass and the seal strip, reduces the requirements for the alignment degree by the glass itself, increases the production rate, and can be particularly applied to frameless vehicle doors.

[0013] In this bracket structure, since the support member is made of plastic material, it is adhered by gel during the process of mounting the glass with a metal bracket, omitting cumbersome operations such as providing tape, effectively increasing the mounting efficiency, and reducing the human consumption.

[0014] The following drawings are only for schematically explaining and interpreting the present invention, and the scope of the present invention is not limited thereto.

Modes for Carrying Out the Invention

[0016] Hereinafter, with reference to the drawings, specific embodiments of the present invention will be described so that the technical features, objects, and effects of the present invention can be better understood.

[0017] (Example 1) As shown in FIGS. 1 to 7, the present invention discloses a bracket structure for supporting and positioning the glass 3 of a vehicle window. The bracket structure includes a support member 1 and an adjustment member 2. The top of the support member 1 is provided with a first support wall 102 and a second support wall 103 that face each other along the vertical direction. A support groove 101 is formed between the first support wall 102 and the second support wall 103. The bottom of the glass 3 is fixed in the support groove 101. The adjustment member 2 is connected to the first support wall 102. The adjustment member 2 has a deformation amount towards the glass 3. By pressing the first support wall 102 with the adjustment member 2 to apply pressure to the glass 3, the offset of the glass 3 can be finely adjusted. When the glass 3 rises to the highest position, it can be adhered to the seal strip on the vehicle body, reducing the requirements for the alignment degree of the glass 3 itself and increasing the production rate.

[0018] Furthermore, the material adopted by the support member 1 is plastic, and the material adopted by the adjustment member 2 is metal. By adopting a metal material for the adjustment member 2, the overall strength of the bracket structure can be enhanced. By adopting a plastic material for the support member 1, it is easy to assemble and fix the glass 3. Among them, the plastic used for the support member 1 is specifically PBT-GF30, and the metal used for the adjustment member 2 is specifically DD13 Zn / Ni.

[0019] In a preferred embodiment of the present invention, as shown in FIGS. 1 to 7, a first member 4 is used for the adjustment member 2. A screw hole 401 is provided in the first member 4. A second member 5 is provided on the support member 1. A through hole 501 communicating with the screw hole 401 is provided in the second member 5. The bolt of the elevator is tightened into the screw hole 401, and the position of the bolt in the screw hole 401 (i.e., the degree of tightening the bolt) is adjusted to adjust the distance between the first member 4 and the second member 5. By driving the adjustment member 2 by the first member 4 to form a certain displacement, pressure is applied to the glass 3 by the adjustment member 2 and the first support wall 102, so that the glass 3 generates a certain offset under the action of the pressure, and the purpose of finely adjusting the glass 3 can be achieved.

[0020] In this embodiment, as shown in FIGS. 1 to 7, the first member 4 is a polygonal cylindrical structure. The adjustment member 2 is provided with a second mounting hole facing the first mounting hole. The first member 4 is fitted into the second mounting hole and locked and fixed in the second mounting hole. The second member 5 is a cylindrical structure. The first mounting hole is provided below the support groove 101 on the support member 1. The second member 5 is fitted into the first mounting hole. At least one ring-shaped retaining protrusion 502 is provided on the outer wall of the second member 5 along the circumferential direction. An engaging groove 104 combined with the retaining protrusion 502 is provided on the inner wall of the first mounting hole. In the assembled state of the second member 5, the retaining protrusion 502 is locked in the engaging groove 104, so as to enhance the stability of mounting the second member 5 in a situation where the second member 5 receives axial pressure, and prevent the second member 5 from detaching from the first mounting hole. Among them, the first member 4 may be a nut, but is not limited thereto.

[0021] It is obvious that the second member 5 can be connected to the support member 1 in other ways. For example, it can be welded or integrally injection molded, but the present invention does not limit the specific connection method.

[0022] In a desirable embodiment of the present invention, as shown in FIG. 6, the hardness of the first member 4 is greater than that of the second member 5, and a first gap 6 is formed between the first member 4 and the second member 5 in the assembled state. Since the first member 4 is provided with a screw hole 401, when finally assembling, by tightening it into the screw hole 401 with a bolt on the elevator, the elevator and the bracket structure are assembled. During the process of tightening the bolt, the first member 4 receives the tightening force of the bolt and moves toward the second member 5, and further moves to the position where the first member 4 and the second member 5 come into contact (at this time, the first gap 6 does not exist). The hardness of the first member 4 is greater than that of the second member 5. After the second member 5 receives the pressure of the first member 4, a slight deformation occurs. Since the second member 5 is provided between the first member 4 and the elevator, by preventing the first member 4 and the elevator from directly contacting and being damaged by receiving force, the first member 4 is supported, buffered and protected (the second member 5 functions similarly to laying a soft washer at the bottom when tightening the screw), and it is also possible to prevent the first member 4 from becoming loose. On the other hand, since one end of the second member 5 away from the first member 4 is flush with the surface of the support member 1, by providing the second member 5, the irregularity of the surface of the support member 1 can also be complemented.

[0023] Furthermore, it is desirable that the width of the first gap 6 is 0.15 mm to 0.25 mm.

[0024] Furthermore, the material of the first member 4 may be stainless steel, but is not limited thereto. The material of the second member 5 may be copper (for example, brass H59), but is not limited thereto.

[0025] Furthermore, the diameter of the through hole 501 is larger than that of the screw hole 401, and during the process of tightening the bolt, its end communicates with the through hole 501 and extends into the screw hole 401 to be fixed by tightening.

[0026] In a preferred embodiment of the present invention, as shown in FIGS. 1, 5, and 7, the adjustment member 2 has a plate-like structure with curvature. The shape of the adjustment member 2 corresponds to the shape of the first support wall 102. The adjustment member 2 covers the surface of the first support wall 102 on the side opposite to the glass 3. A second gap 7 is formed between the middle part of the adjustment member 2 and the surface of the first support wall 102 on the side opposite to the glass 3. The top of the adjustment member 2 abuts against the surface of the first support wall 102 on the side opposite to the glass 3, and the top of the adjustment member 2 applies pressure to the top of the first support wall 102, so that the first support wall 102 presses the glass 3, and thus the offset can be finely adjusted.

[0027] Specifically, as shown in FIG. 1, buckles 105 are respectively provided at the corners of the first support wall 102 of the support member 1. Each buckle 105 connects the adjustment member 2 and the support member 1 by clamping the edge of the adjustment member 2.

[0028] In a preferred embodiment of the present invention, as shown in FIG. 2, strip-shaped notches 106 are formed at positions near the buckles 105 on both sides of the top of the support member 1. In the present invention, since the support member 1 is a plastic member and the adjustment member 2 is a metal member, when assembling, it is necessary to press the support member 1 to generate deformation to achieve stable assembly. Since the support member 1 itself is also hard, it is difficult for the support member 1 to deform even when it has a certain thickness. Therefore, by opening the notches 106 in the support member 1, the deformation ability of the support member 1 at a position near the buckle 105 can be enhanced, and smooth assembly can be realized.

[0029] In a preferred embodiment of the present invention, as shown in FIGS. 1, 2, 5, and 7, the length of the first support wall 102 in the vertical direction is longer than the length of the second support wall 103 in the vertical direction. A clamping member 8 is provided at the upper part of the surface of the first support wall 102 facing the glass 3. In the assembled state, the clamping member 8 is combined with the glass 3 by interference fit and applies a pressing force to the glass 3.

[0030] Furthermore, the clamp member 8 has a layered structure covering the surface of the first support wall 102. Among them, the clamp member 8 is preferably formed of a thermoplastic elastomer material (TPE). The clamp member 8 is additionally installed on the support member 1 by double injection molding or injection molding with a dual material. The clamp member 8 and the outer surface of the glass 3 are in an interference state, and the interference amount generated in the actual mounting state generates a pressing force on the outer surface of the glass 3, not only joining the first support wall 102 and the glass 3 more tightly, but also applying a pressure towards the inner side of the window to the glass 3 after assembly, thereby achieving the effect of finely adjusting the offset of the glass 3. Among them, the interference amount of the clamp member 8 on the glass 3 is 0.5 mm to 1.5 mm.

[0031] In a preferred embodiment of the present invention, as shown in FIG. 7, adhesive portions 9 are provided between the two opposing inner walls of the support groove 101 and between the bottom wall of the support groove 101 and the glass 3. The glass 3 is adhered to the support groove 101 by the adhesive portions 9, and three sides of the glass 3 are adhered by the adhesive portions 9, so that the glass 3 can be assembled more stably.

[0032] However, the adhesive portion 9 is composed of an adhesive, and the adhesive is composed of a general single-component polyurethane adhesive, a two-component polyurethane adhesive, or a thermosetting polyurethane adhesive. In view of the curing time of the adhesive and the mounting precision of the glass 3, it is preferable to use a two-component polyurethane adhesive and a thermosetting polyurethane adhesive.

[0033] In the present invention, the first support wall 102 has a longer length in the vertical direction than the length of the second support wall 103 in the vertical direction. By installing the first support wall 102, the contact area between the support member 1 and the glass 3 can be increased, and the stress received by the support portion of the support member 1 during vehicle running can be reduced. By installing the second support wall 103, it is easy to inject the adhesive, and the adhesive can be embedded in the support groove 101. On the other hand, during the injection of the adhesive, the adhesive should not exceed the clamp member 8 to avoid the clamp member 8 being damaged due to too much adhesive.

[0034] Furthermore, as shown in FIG. 5, a fourth gap 10 is formed between two opposing inner walls of the support groove 101 and the bottom wall of the support groove 101 and the glass 3 for providing an adhesive portion 9. By providing the fourth gap 10, the adhesive portion 9 is adhered to three sides of the glass 3 to form a "U"-shaped adhesive portion 9, which can effectively increase the storage amount of the gel and stably adhere the glass 3.

[0035] In a preferred embodiment of the present invention, as shown in FIG. 2, a plurality of reinforcing ribs 1011 extending in the vertical direction are provided on the inner wall of the support groove 101, and each reinforcing rib 1011 is arranged at intervals in the horizontal direction. A third gap (the third gap is a part of the fourth gap 10) is formed between the reinforcing rib 1011 and the glass 3. By providing each reinforcing rib 1011, while preventing a shift from occurring after the glass 3 and the support member 1 are assembled, the installation of the reinforcing rib 1011 contributes to the storage of the gel and can enhance the adhesion stability between the glass 3 and the support member 1.

[0036] However, the width of the third gap may be 0.2 mm to 1 mm, but is not limited thereto.

[0037] During the assembly of the present invention, after the glass 3 and the support member 1 are mounted and fixed, the outer adjustment member 2 is mounted. The adjustment member 2 and the support member 1 are assembled and fixed by a buckle 105 structure. After the adjustment member 2 and the support member 1 are assembled, a certain movement margin is maintained between them (that is, a first gap 6 is maintained between the first member 4 and the second member 5). When loading the assembled assay glass, when tightening the bolt on the elevator and the first member 4 on the adjustment member 2, an interference amount occurs on the surfaces of the clamp member 8 and the glass 3. However, since the adjustment member 2 and the first support wall 102 on the support member 1 are joined to each other, the amount of offset of the top of the glass 3 inward can be adjusted by adjusting the tightening degree of the bolt in the screw hole on the first member 4 during assembly and adjusting the pressure applied to the glass 3 by the first support wall 102.

[0038] The bracket structure according to the present invention has the following features and advantages. 1. The bracket structure finely adjusts the offset of the glass 3 so that when the glass 3 rises to the highest position, it is locked to the seal strip on the vehicle body to ensure the joint between the glass 3 and the seal strip, reduce the requirements for the degree of coincidence by the glass 3 itself, increase the production rate, and can be particularly applied to frameless vehicle doors. 2. In the bracket structure, since the support member 1 is made of plastic material, the cumbersome operations such as sticking with gel and providing tapes during the installation of the glass by a metal bracket are omitted, the installation efficiency can be effectively increased, and the human consumption can be reduced.

[0039] (Example 2) The present invention provides a frameless vehicle door including the glass 3 and the above bracket structure. The bottom of the glass 3 is fixed to the bracket structure, and by applying pressure to the glass 3 by the bracket structure, the top of the glass 3 and the seal strip on the vehicle body can be locked.

[0040] Furthermore, the glass 3 may be tempered glass or semi-tempered laminated glass, but is not limited thereto. Desirably, it may be semi-tempered laminated glass.

[0041] (Example 3) The present invention provides a vehicle including the above frameless vehicle door.

[0042] The above is only a schematic description of the specific embodiments of the present invention, but the scope of the present invention is not limited thereto. It should be understood that all equivalent changes and corrections made by those skilled in the art without departing from the idea and principle of the present invention belong to the protection scope of the present invention.
