Description

Technical Field

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

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

Background Art

[0003] As consumers' demands for fashion, sports, and personality 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 lifting of the glass every time the door is opened and closed should also be automatically controlled.

[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 lifting of the window. Without the guidance of a frame, such problems become more important.

Summary of the Invention

Problems to be Solved by the Invention

[0005] At present, the glass in frameless vehicle doors is supported by brackets, which are mostly made of metal steel (aluminum alloy). Once the glass is attached to the bracket (specifically, when bonding the metal bracket and glass, tape is first applied to the appropriate position on the glass, and then gel is injected through a gel injector and hardened), the angle and mounting relationship formed between the bracket and the glass cannot be changed. The bracket is then clamped or tightened with a connecting structure on the lifting mechanism to complete the installation, but once the car window is fixed to the lifting mechanism, it is difficult to correct the precise position of the window. Therefore, the main problems that exist when installing frameless vehicle doors and glass in existing vehicles are as follows: 1. The metal bracket structure is very rigid, so tape is first applied to the bottom to prevent direct contact between the glass and the metal bracket. However, the addition of the tape application process makes the operation complicated and difficult to install. 2. During the gel application process, paper tape (to protect the glass surface) and rubber strips (to prevent gel from entering) are applied around the bracket, and then the entire area of ​​the rubber strips is sealed with transparent tape. Finally, the rubber strips on both sides are secured with paper tape to ensure a tight seal. However, the entire process takes about 30 minutes to complete, and this method is time-consuming and affects the efficiency of fitting. 3. Two existing gel curing methods are used. The first method involves allowing the gel to air dry (for about 40 to 50 minutes), removing all paper tape and rubber strips around the bracket before it is completely cured, and then performing gel cleaning and tolerance adjustment using a detection tool. However, complete curing takes about an hour. The second method involves drying with a heater gun, first heating for 3 to 5 minutes to observe the gel's state, removing all paper tape and rubber strips around the bracket before it is completely cured, then performing gel cleaning and tolerance adjustment using a detection tool, and finally placing it on a table and heating for 3 to 5 minutes to cure it. In both of the above methods, the two-component gel is quite hard after curing, so it is necessary to clean the gel while the bracket is semi-cured. At this time, the bracket should be removed from the work equipment, but because the bracket is semi-cured, an offset occurs between the glass and the bracket, and it must be positioned using a detection tool. In short, the natural curing time is long, and the heat curing operation is complex. 4. When the glass and bracket are adhered together, they are all loosely assembled (i.e., a gap of 1-3 mm is created between the glass surface and the inner wall of the bracket groove), and this mounting method does not allow the glass to be subjected to preload, making it impossible to guarantee a stable motion trajectory during the raising and lowering of the glass, and furthermore, it is impossible to guarantee a good combination effect with the sealing strip when the glass rises to its highest position. 5. Due to the structural characteristics of the metal bracket and the fact that the bracket groove and glass are joined by a gap, there is no adjustment space after the glass has been installed and hardened. Therefore, unless the glass size matches to a very precise tolerance (for example, a tolerance of ±0.5 for glass matching), smooth installation cannot be guaranteed.

[0006] Therefore, when combining the glass and bracket, there are problems such as difficulty in installation, long wear time, and poor matching effect.

[0007] The present invention aims to provide a bracket structure, a frameless vehicle door, and a vehicle that can increase production efficiency by fine-tuning the offset of the glass using a bracket, thereby reducing the requirement for the frameless vehicle door to match the glass itself.

[0008] Another objective of this invention is to provide a bracket structure, a frameless vehicle door, and a vehicle that improve installation efficiency and reduce manual labor consumption by eliminating complicated operations such as applying tape to the bracket during glass installation. [Means for solving the problem]

[0009] To achieve the above objective, the present invention provides a bracket structure for supporting and positioning a car window glass, wherein the bracket structure comprises a support member and an adjustment member, the support member has a first support wall and a second support wall facing each other, 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, the adjustment member has a deformation amount toward the glass, and by pressing the first support wall and applying pressure to the glass, the top of the glass is provided to adhere to a seal strip on the car body.

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

[0011] The present invention provides a vehicle equipped with the above-mentioned frameless vehicle door. [Effects of the Invention]

[0012] This bracket structure fine-tunes the offset of the glass, ensuring that when the glass rises to its highest position, it engages with the sealing strip on the vehicle body, guaranteeing a secure bond between the glass and the sealing strip. This reduces the requirement for a perfect match from the glass itself, increases production efficiency, and can be particularly applied to frameless vehicle doors.

[0013] In this bracket structure, since the support member is made of plastic, it is possible to effectively improve installation efficiency and reduce manual labor by eliminating the need for complicated operations such as attaching the glass with a gel during the process of mounting it with a metal bracket and applying tape.

[0014] The following drawings are for illustrative purposes only and do not limit the scope of the present invention. [Brief explanation of the drawing]

[Figure 6] Schematic diagram of the positions of the first member and the second member in the bracket structure according to the present invention [Figure 7] Another schematic cross-sectional view of the bracket structure and glass assembled according to the present invention. [Modes for carrying out the invention]

[0016] Specific embodiments of the present invention will be described below with reference to the drawings, so that the technical features, objectives, and effects of the present invention may 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 by 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 bonded 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​​ 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 projection 502 is provided on the outer wall of the second member 5 along the circumferential direction. An engaging groove 104 combined with the retaining projection 502 is provided on the inner wall of the first mounting hole. In the assembled state of the second member 5, the retaining projection 502 is locked in the engaging groove 104, thereby enhancing the stability of mounting the second member 5 in a situation where the second member 5 receives axial pressure and preventing 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 self-evident 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 preferred embodiment of the present invention, as shown in Figure 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, the elevator and bracket structure are assembled by tightening the screw hole 401 with a bolt on the elevator during final assembly. During the tightening of the bolt, the first member 4 moves toward the second member 5 due to the tightening force of the bolt, and further moves to a 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 being subjected to the pressure of the first member 4, the second member 5 undergoes a slight deformation. Since the second member 5 is provided between the first member 4 and the elevator, it prevents the first member 4 from being damaged by direct contact and force between the first member 4 and the elevator. This allows the second member 5 to support, buffer, and protect the first member 4 (similar to placing a soft washer at the bottom when tightening a screw), and also prevents the first member 4 from becoming loose. On the other hand, since one end of the second member 5 that is separated from the first member 4 is flush with the surface of the support member 1, the provision of the second member 5 can also compensate for the irregularity of the surface of the support member 1.

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

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

[0025] Furthermore, the through-hole 501 has a larger diameter than the screw hole 401, and as the bolt is tightened, its end extends through the through-hole 501 into the screw hole 401 and is secured by tightening.

[0026] In a preferred embodiment of the present invention, as shown in Figures 1, 5, and 7, the adjustment member 2 has a curvatured plate-like structure, 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 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 opposite to the glass 3, the top of the adjustment member 2 abuts against the surface of the first support wall 102 opposite to the glass 3, the top of the adjustment member 2 applies pressure to the top of the first support wall 102, and the offset can be finely adjusted by the first support wall 102 pressing against the glass 3.

[0027] Specifically, as shown in Figure 1, buckles 105 are provided at each corner of the first support wall 102 of the support member 1, and each buckle 105 tightens the edge of the adjustment member 2, thereby connecting the adjustment member 2 and the support member 1.

[0028] In a preferred embodiment of the present invention, as shown in Figure 2, strip-shaped notches 106 are formed on both sides of the top of the support member 1 at positions close to the buckle 105. In the present invention, the support member 1 is a plastic member and the adjustment member 2 is a metal member. Therefore, when assembling, the only way to achieve stable assembly is to press the support member 1 to generate deformation. Since the support member 1 itself is hard, deformation is difficult to occur even when the support member 1 has a certain thickness. By creating notches 106 in the support member 1, the deformation capacity of the support member 1 at a position close to the buckle 105 is increased, and smooth assembly can be achieved.

[0029] In a preferred embodiment of the present invention, as shown in Figures 1, 2, 5, and 7, the first support wall 102 has a longer vertical length than the second support wall 103, and a clamp member 8 is provided on the upper part of one surface of the first support wall 102 facing the glass 3. In the assembled state, the clamp member 8 is fitted to the glass 3 by interference fit, applying a pressing force to the glass 3.

[0030] Furthermore, the clamp member 8 has a layered structure that covers the surface of the first support wall 102. Preferably, the clamp member 8 is made of thermoplastic elastic material (TPE). The clamp member 8 is added to the support member 1 by double injection molding or double-layer injection molding, and the clamp member 8 and the outer surface of the glass 3 are in interference. The amount of interference that occurs in the actual installed state generates a pressing force on the outer surface of the glass 3, not only to more tightly join the first support wall 102 and the glass 3, but also to apply pressure to the glass 3 toward the inside of the window after assembly, thereby achieving the effect of fine-tuning the offset of the glass 3. The amount of interference between the clamp member 8 and the glass 3 is 0.5 mm to 1.5 mm.

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

[0032] However, the adhesive portion 9 consists of an adhesive, and the adhesive consists of a general single-component polyurethane adhesive, a two-component polyurethane adhesive, or a thermosetting polyurethane adhesive. Considering the curing time of the adhesive and the precision of the glass 3 attachment, it is desirable to use a two-component polyurethane adhesive or a thermosetting polyurethane adhesive.

[0033] In this invention, 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. The installation of the first support wall 102 increases the contact area between the support member 1 and the glass 3, thereby reducing the stress on the support portion of the support member 1 during vehicle operation. The installation of the second support wall 103 facilitates the injection of adhesive, allowing the adhesive to be embedded in the support groove 101. On the other hand, during the injection of adhesive, the amount of adhesive should not exceed the clamp member 8, so as not to cause the clamp member 8 to break due to excessive adhesive.

[0034] Furthermore, as shown in Figure 5, a fourth gap 10 is formed between the two opposing inner walls of the support groove 101 and the bottom wall of the support groove 101 and the glass 3 to provide an adhesive portion 9. By providing the fourth gap 10, the adhesive portion 9 adheres to three sides of the glass 3, forming a "U" shaped adhesive portion 9, which can effectively increase the amount of gel that can be stored and allow the glass 3 to adhere stably.

[0035] In a preferred embodiment of the present invention, as shown in Figure 2, a plurality of vertically extending reinforcing ribs 1011 are provided on the inner wall of the support groove 101, and each reinforcing rib 1011 is spaced apart horizontally, forming a third gap (the third gap is part of the fourth gap 10) between the reinforcing rib 1011 and the glass 3. By providing each reinforcing rib 1011, shifting occurs after the glass 3 and the support member 1 are assembled, while the installation of the reinforcing ribs 1011 contributes to gel storage and enhances the adhesive 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 to this.

[0037] In this invention, during assembly, the outer adjustment member 2 is attached after the glass 3 and support member 1 are mounted and fixed, and the adjustment member 2 and support member 1 are assembled and fixed together by a buckle 105 structure. After the adjustment member 2 and support member 1 are assembled, a certain amount of extra movement is maintained between them (i.e., a first gap 6 is maintained between the first member 4 and the second member 5). When loading the assembled assay glass, interference occurs between the clamp member 8 and the surface of the glass 3 when tightening the bolt on the elevator and the first member 4 on the adjustment member 2. However, since the adjustment member 2 and the first support wall 102 on the support member 1 are joined to each other, the amount by which the top of the glass 3 is offset inward can be adjusted by adjusting the degree to which the bolt in the screw hole on the first member 4 is tightened during assembly to adjust 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, ensuring that when the glass 3 rises to its highest position, it engages with the seal strip on the vehicle body, thereby guaranteeing a connection between the glass 3 and the seal strip. This reduces the requirement for a degree of alignment on the glass 3 itself, increases production efficiency, and can be applied in particular to frameless vehicle doors. 2. In this bracket structure, since the support member 1 is made of plastic material, it adheres with gel during the process of attaching the glass with the metal bracket, eliminating the need for complicated operations such as applying tape, thereby effectively increasing the installation efficiency and reducing manual labor.

[0039] (Example 2) The present invention provides a frameless vehicle door comprising a glass 3 and the bracket structure described above, wherein the bottom of the glass 3 is fixed to the bracket structure, and the bracket structure applies pressure to the glass 3, thereby locking the top of the glass 3 with a seal strip on the vehicle body.

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

[0041] (Example 3) The present invention provides a vehicle equipped with the above-described frameless vehicle door.

[0042] The above has merely provided a general overview of specific embodiments of the present invention, but the scope of the present invention is not limited thereto. Those skilled in the art should understand that any equivalent changes and modifications made while remaining within the spirit and principles of the present invention fall within the scope of protection of the present invention.
