Frameless door glass assembly and vehicle

Abstract

This invention relates to a frameless door glass assembly and a vehicle. The frameless door glass assembly includes: a guide rail; and glass, the glass being movably mounted to the guide rail and performing a preset lifting stroke along the guide rail. The preset lifting stroke of the glass includes a first stroke and a second stroke arranged sequentially. In the first stroke, the glass is configured to move along a direction parallel to a B-pillar sealing strip. In the second stroke, the glass is configured to move upwards while simultaneously moving towards the B-pillar sealing strip to contact and engage with it. This invention enables the glass to actively conform to the B-pillar sealing strip at the end of its upward movement, thereby optimizing the sealing fit at the B-pillar without relying on glass pre-bending or changing sealing strip parameters. It resolves the contradiction between interference and top insertion in traditional designs, significantly improving the sealing reliability at this location while ensuring the smoothness of the overall glass movement and structural simplicity.

Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to frameless door glass assemblies and vehicles. Background Technology

[0002] Frameless doors are widely used in modern automobiles, especially sporty and high-end models, due to their sleek and aesthetically pleasing design. The sealing effect of their side windows primarily relies on the tight fit between the glass and the surrounding sealing structure. The upper sealing of the door is typically achieved in two ways: first, the window automatically rises a certain distance after the door is closed, allowing the top of the glass to insert into the sealing strip on the roof side, achieving an upper edge seal; second, the side window glass interferes with the sealing strip at the B-pillar of the vehicle body through the pre-bending shape of the glass in the Y-direction (left-right direction), thus forming a lateral seal. However, in actual use, the sealing effect in the B-pillar area often becomes a weak point in the frameless door sealing system.

[0003] Because the pre-bending amount of glass is limited by materials and processes, its curvature adjustment range is also limited. This often results in insufficient adhesion between the glass and the B-pillar sealing strip, making leakage prone to occur at this point and affecting the vehicle's sound insulation, waterproofing, and airtightness. If the hardness of the sealing strip is increased or the interference is increased to enhance the seal at the B-pillar, it will make it difficult for the glass to smoothly insert into the top sealing strip when the door is closed, affecting the integrity of the seal and the smoothness of operation. Conversely, if the stiffness of the B-pillar sealing strip is reduced or the interference is decreased to facilitate glass insertion, the reliability of the seal at the B-pillar will be weakened, making it difficult to fundamentally solve the leakage problem. Summary of the Invention

[0004] Based on this, a frameless door glass assembly and vehicle are provided, which directly optimizes the sealing fit at the B-pillar without relying on glass pre-bending or changing the sealing strip parameters, significantly improving the sealing reliability at this location, while ensuring the smoothness of the overall glass movement and the simplicity of the structure.

[0005] In a first aspect, a frameless door glass assembly is provided, comprising: a guide rail; and glass, the glass being movably mounted to the guide rail and capable of performing a preset lifting stroke along the guide rail; wherein the preset lifting stroke of the glass includes a first stroke and a second stroke arranged sequentially; in the first stroke, the glass is configured to move along a direction parallel to a sealing strip of a B-pillar; in the second stroke, the glass is configured to move upward while moving towards the sealing strip of the B-pillar to contact and engage with the sealing strip of the B-pillar.

[0007] Preferably, the second guide surface is an inclined plane or an arc surface.

[0008] Preferably, the frameless door glass assembly further includes: an upper bracket mounted to the guide rail, the upper bracket being movable along the first guide surface and the second guide surface, and fixed to the glass; and a lower bracket mounted separately from the upper bracket to the guide rail and located below the upper bracket, the lower bracket being movable along the first guide surface, the lower bracket supporting the glass, and the lower bracket being configured such that the glass is displaceable relative to the lower bracket in a front-rear direction.

[0009] Preferably, the lower bracket extends in the front-to-back direction and has an upward-opening groove, with the bottom of the glass located within the groove, so that the lower bracket supports the glass.

[0010] Preferably, the lower bracket includes: a first movable member, the first movable member being movable along the first guide surface; and a first connecting plate, the first connecting plate being fixed to the first movable member, the top of the first connecting plate having the groove.

[0014] In a second aspect, a vehicle is provided equipped with frameless door glass assemblies as described in the first aspect.

[0015] The aforementioned frameless door glass assembly allows the glass to actively conform to the B-pillar sealing strip during its final rise, thereby directly optimizing the sealing fit at the B-pillar without relying on glass pre-bending or altering the sealing strip parameters.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be 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 the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] The forward direction refers to the direction towards the front of the vehicle (i.e., the direction of travel), while the backward direction refers to the direction towards the rear of the vehicle (i.e., the direction opposite to the forward direction).

[0034] The following is combined with Figures 1 to 8 A frameless door glass assembly according to an embodiment of the present invention will be described.

[0035] like Figures 1 to 3 , Figure 8 As shown, the frameless door glass assembly of the present invention includes: a guide rail 100 and a glass 200.

[0036] The glass 200 is movably mounted to the guide rail 100, and the glass 200 can perform a preset lifting stroke along the guide rail 100.

[0037] The preset lifting stroke of the glass 200 includes a first stroke and a second stroke set sequentially.

[0038] In the first stroke, the glass 200 is configured to move along a direction parallel to the sealing strip of the B-pillar 600.

[0039] In the second stroke, the glass 200 is configured to move towards the sealing strip of the B-pillar 600 while moving upward, so as to contact and engage with the sealing strip of the B-pillar 600.

[0040] This invention enables the glass 200 to actively adjust its relative position to the sealing strip at the B-pillar 600 during the second upward stroke of its movement. This achieves a tight fit between the glass and the sealing strip at the B-pillar 600 without relying on glass pre-bending or changing the rigidity of the sealing strip, significantly improving the sealing reliability and stability of the B-pillar area. It also ensures the smoothness of the glass insertion process into the top sealing strip, enhancing the overall sound insulation, waterproofing, and airtightness of the frameless door system. Furthermore, the invention is simple in structure, easy to implement, and contributes to improved product durability and user experience.

[0041] In an exemplary embodiment, the second stroke ranges from 10 mm to 15 mm in the height direction. Because the second stroke accounts for a small portion of the overall upward movement and is the last segment formed, it is also referred to as the final stroke.

[0042] In an exemplary implementation, such as Figure 1 As shown, the guide rail 100 includes a first guide surface 101 and a second guide surface 102. The first guide surface 101 is configured parallel to the sealing strip of the B-pillar 600. The second guide surface 102 is connected to the first guide surface 101 and is bent relative to the first guide surface 101 in a direction closer to the B-pillar 600 (i.e., bent backward), so that the glass 200 can move upward while approaching the sealing strip of the B-pillar 600 to contact and form a fit with the sealing strip of the B-pillar 600. Figure 1 As shown, the sealing strips of the first guide surface 101 and the B-pillar 600 are both inclined to a certain degree. Specifically, the top of the first guide surface 101 is further back than the bottom of the first guide surface 101, and the top of the sealing strip of the B-pillar 600 is further back than the bottom of the sealing strip of the B-pillar 600.

[0043] In the first stroke, the glass 200 moves along the first guide surface 101.

[0044] In the second stroke, the glass 200 moves along the second guide surface 102.

[0045] In one implementation scheme, such as Figure 1 As shown, the second guide surface 102 is an inclined plane.

[0046] When the second guide surface 102 is an inclined plane, the two second guide surfaces 102 are parallel, that is, the angle between the front second guide surface 102 and the front first guide surface 101 is equal to the angle between the rear second guide surface 102 and the rear first guide surface 101.

[0047] In another embodiment, the second guide surface 102 may also be an arc surface (not shown in the figure). The shape of the second guide surface 102 is not limited thereto, as long as it can achieve the above-mentioned functions.

[0048] like Figure 7As shown, when the second guide surface 102 is an arc surface, the two second guide surfaces 102 have the same curvature. The distance between the centers of the two second guide surfaces 102 (i.e., the distance from center C1 to center C2) is equal to the distance between the tops of the two first guide surfaces 101 (i.e., the distance from the top 103 of the front first guide surface 101 to the top 104 of the rear first guide surface 101), and the distance d1 from the center C1 of the front second guide surface 102 to the top 103 of the front first guide surface 101 is equal to the distance d2 from the center C2 of the rear second guide surface 102 to the top 104 of the rear first guide surface 101.

[0049] In an exemplary implementation, such as Figures 1 to 3 As shown, the frameless door glass assembly further includes an upper bracket 300 and a lower bracket 400.

[0050] The upper bracket 300 is mounted to the guide rail 100 and can move along the first guide surface 101 and the second guide surface 102, and is fixed to the glass 200.

[0051] The lower bracket 400 is separately mounted to the guide rail 100 and located below the upper bracket 300. The lower bracket 400 is movable along the first guide surface 101 and supports the glass 200. The lower bracket 400 is configured such that the glass 200 can be displaced relative to the lower bracket 400 in the front-rear direction during a second stroke. The separation of the lower bracket 400 from the upper bracket 300 means that the relative positions of the lower bracket 400 and the upper bracket 300 in the front-rear direction can change.

[0052] In an exemplary implementation, such as Figure 3 and Figure 4 As shown, the lower bracket 400 extends in the front-to-back direction and has an upward-opening groove 404 that extends through the lower bracket 400 in the front-to-back direction. The bottom of the glass 200 is located within the groove 404 so that the lower bracket 400 supports the glass 200.

[0053] During the first stroke, the upper bracket 300 and the lower bracket 400 move along the first guide surface 101, while the glass 200 does not move relative to the slide 404.

[0054] In the second stroke, the upper bracket 300 moves along the second guide surface 102, the lower bracket 400 moves along the first guide surface 101, and the bottom of the glass 200 moves along the groove 404 relative to the lower bracket 400 toward the B-pillar 600 (i.e., backward), so that the glass 200 can approach the sealing strip of the B-pillar 600 while moving upward, so as to contact and cooperate with the sealing strip of the B-pillar 600.

[0055] In an exemplary embodiment, the upper bracket 300 is fixed to the glass 200 by means of snap-fit ​​connection or adhesive bonding.

[0056] When using a snap-fit ​​connection, the upper bracket 300 is equipped with hooks, and the corresponding edge of the glass 200 has a corresponding groove, or the two use an interlocking snap-fit ​​structure to achieve quick assembly and reliable connection through snap-fit. When using an adhesive method, a high-strength structural adhesive is applied between the contact surfaces of the upper bracket 300 and the glass 200, forming a strong adhesive layer after curing. Whether using a snap-fit ​​connection or adhesive bonding, sufficient connection strength and rigidity are ensured between the upper bracket 300 and the glass 200, making them a single moving unit. This allows them to reliably follow the guide path of the guide rail 100 and withstand corresponding forces, enabling the glass 200 to accurately move backward and fit during the second stroke. These two methods can be selected based on specific production processes and design requirements.

[0057] In one implementation scheme, such as Figure 2 As shown, the lower bracket 400 includes: a first movable member 401 and a first connecting plate 403.

[0058] The first movable component 401 is capable of moving along the first guide surface 101.

[0059] The first connecting plate 403 is fixedly connected to the first moving member 401, and the top of the first connecting plate 403 has the aforementioned sliding groove 404 (see details below). Figure 4 This allows the glass 200 to move relative to the first connecting plate 403 in the front-rear direction along the groove 404.

[0060] In an exemplary implementation, such as Figure 2 As shown, the upper bracket 300 includes: a second movable member 301 and a second connecting plate 303.

[0061] The second moving member 301 is capable of moving along the first guide surface 101 and the second guide surface.

[0062] The second connecting plate 303 is fixed to the second moving member 301 and fixed to the glass 200, so that the glass 200 is relatively fixed to the upper bracket 300 and moves along the first guide surface 101 and the second guide surface with the upper bracket 300.

[0063] In an exemplary implementation, such as Figure 1As shown, two guide rails 100 are provided and distributed along the front-rear direction. The mutually distant sides of the two guide rails 100 include the first guide surface 101 and the second guide surface 102. Specifically, a car door is provided with two guide rails 100, including a first guide rail 110 and a second guide rail 120. The first guide rail 110 is located in front of the second guide rail 120. The front surface of the first guide rail 110 includes the first guide surface 101 and the second guide surface 102, and the rear surface of the second guide rail 120 includes the first guide surface 101 and the second guide surface 102.

[0064] There are two upper brackets 300, specifically including a first upper bracket 310 and a second upper bracket 320, and there are two lower brackets 400, specifically including a first lower bracket 410 and a second lower bracket 420.

[0065] An upper bracket 300 and a lower bracket 400 are mounted on a guide rail 100, that is, the first upper bracket 310 and the first lower bracket 410 are mounted on the first guide rail 110, and the second upper bracket 320 and the second lower bracket 420 are mounted on the second guide rail 120.

[0066] like Figure 5 As shown, in the prior art, the movement of the glass in a frameless car door during door closing is as follows: After the door is closed, the glass 200 needs to rise a certain distance from the open position 202 before it can fit against the sealing strip. After rising a certain distance, the glass 200 moves from the open position 202 towards the interior of the vehicle to the closed position 201, to fit against the first sealing strip 510 of the vehicle body and the second sealing strip 520 of the B-pillar 600. From Figure 5 It can be seen that during assembly, it is necessary to control the tolerance of the glass position in the left-right direction and the front-back direction of the vehicle.

[0067] like Figure 6 As shown, in this invention, within its travel range, the outer surface of the glass 200 is flush with or substantially flush with the outer surface of the second sealing strip 520. The glass 200 of this invention does not need to move towards the vehicle interior; that is, the open position 202 and the closed position 201 are aligned in the left-right direction of the vehicle, with misalignment only in the front-back direction. Therefore, from... Figure 6 It can be seen that during assembly, only the tolerance in the front-to-back direction needs to be controlled, and the tolerance in the left-to-right direction does not need to be controlled.

[0068] This invention also provides a vehicle equipped with the aforementioned frameless door glass assembly. The frameless door glass assembly is mounted on the front door 700 of the vehicle (see attached diagram). Figure 8 )superior.

[0069] Other components and functions of the vehicle according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail to reduce redundancy. The vehicle can be a fuel vehicle, a natural gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc., and are not limited in the present invention.

[0070] The operation of the frameless car door glass assembly according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0071] The preset lifting stroke includes two strokes:

[0072] First stroke: The upper bracket 300 and the lower bracket 400 move along the first guide surface 101 to push the glass 200 upward and parallel to the sealing strip of the B-pillar 600 (see details). Figure 2 ).

[0073] Second stroke (i.e., final stroke): The upper bracket 300 moves from the first guide surface 101 to the second guide surface 102. During upward movement along the second guide surface 102 (see also...) Figure 3 Since the upper bracket 300 and the glass 200 are relatively fixed (the two will not produce relative displacement), the glass 200 moves upward and backward along the second guide surface 102 following the upper bracket 300, that is, it gradually approaches the sealing strip of the B-pillar 600.

[0074] During this process, the lower bracket 400 continues to move upward along the first guide surface 101. Since the groove 404 opens upward and extends through the lower bracket 400 in the front-to-back direction, the bottom of the glass 200 will move backward relative to the lower bracket 400 along the groove 404. This prevents the lower bracket 400 from interfering with the backward movement of the glass 200, allowing the glass 200 to move smoothly upward along the second guide surface 102 while approaching the sealing strip of the B-pillar 600. During this process, the lower bracket 400 continues to support the glass 200 in the vertical direction.

[0075] As can be seen from the above process, the change of glass 200 from open position 202 to closed position 201 only involves displacement in the front and rear directions, and no longer requires pre-bending of glass 200 itself in the left and right directions, thus reducing the space required for the left and right adjustment mechanism of the car door.

[0076] 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.

[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
