[0053] The following is for reference. Figures 1-10 A frameless glass car door 1000 according to an embodiment of the present invention is described.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the frameless glass car door 1000 according to an embodiment of the present invention includes a door sheet metal assembly 100, a first guide rail reinforcing plate 200, a second guide rail reinforcing plate 300, a third guide rail reinforcing plate 400, a fourth guide rail reinforcing plate 500, a first guide rail 600, and a second guide rail 700.

[0055] Specifically, such as Figure 3 and Figure 5 As shown, the first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 are connected to the door sheet metal assembly 100. The first guide rail reinforcing plate 200 and the second guide rail reinforcing plate 300 are located above the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500. The first guide rail reinforcing plate 200 is located on the side of the second guide rail reinforcing plate 300 closer to the door hinge, and the third guide rail reinforcing plate 400 is located on the side of the fourth guide rail reinforcing plate 500 closer to the door hinge.

[0056] The first guide rail 600 is located on the side of the second guide rail 700 near the door hinge. The upper and lower ends of the first guide rail 600 are connected to the first guide rail reinforcing plate 200 and the third guide rail reinforcing plate 400, respectively. The upper and lower ends of the second guide rail 700 are connected to the second guide rail reinforcing plate 300 and the fourth guide rail reinforcing plate 500, respectively. The first guide rail 600 and the second guide rail 700 are tightly connected to the door sheet metal assembly 100 via the first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400, and the fourth guide rail reinforcing plate 500, ensuring the strength of the first guide rail 600 and the second guide rail 700.

[0057] According to an embodiment of the present invention, the frameless glass door 1000 is constructed by connecting a first guide rail reinforcing plate 200 and a third guide rail reinforcing plate 400 to the upper and lower ends of a first guide rail 600, and a second guide rail reinforcing plate 300 and a fourth guide rail reinforcing plate 500 to the upper and lower ends of a second guide rail 700, respectively. The first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400, and the fourth guide rail reinforcing plate 500 are connected to the door sheet metal assembly 100. This increases the reliability of the connection between the first guide rail 600 and the second guide rail 700 and the door sheet metal assembly 100, ensures the connection strength at the first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400, and the fourth guide rail reinforcing plate 500, and reduces the shaking during the closing or lifting of the glass door.

[0058] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the door sheet metal assembly 100 includes an inner panel 1, an outer panel 4, and an inner waistline reinforcing plate 2. The outer panel 4 is located outside the inner panel 1 and connected to it. The outer edge of the outer panel 4 has a flange structure extending towards the inner panel 1, which can be sheet metal connected to the inner panel 1. The flange defines a space between the inner panel 1 and the outer panel 4 for installing other components of the door sheet metal assembly 100. The inner waistline reinforcing plate 2 is located between the inner panel 1 and the outer panel 4 and connected to the inner panel 1. There are two weld points on the rear side of the inner waistline reinforcing plate 2 in the X direction. The inner waistline reinforcing plate 2 and the inner panel 1 are welded together by the two X-direction weld points, which can enhance the waistline rigidity, prevent the frameless glass door 1000 from shaking when closing, and improve the durability of the vehicle body.

[0059] It should be noted that in this application, the terms "inner side" and "outer side" refer to the side facing outwards from the vehicle when the frameless glass door 100 is closed, and the side facing inwards from the vehicle. Furthermore, the descriptions of the X, Y, and Z directions in this application are also based on the direction of the frameless glass door 100 when it is closed. Here, the X direction is the vehicle's front-to-back direction, the Y direction is the vehicle's width direction (i.e., left-to-right direction), and the Z direction is the vehicle's height direction.

[0060] The first guide rail reinforcing plate 200 and the second guide rail reinforcing plate 300 are located between and connected to the inner plate 1 and the inner waistline reinforcing plate 2. The third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 are located between the inner plate 1 and the outer plate 4 and connected to the inner plate 1. The upper end of the first guide rail 600 is located between the first guide rail reinforcing plate 200 and the inner plate 1, and the lower end is located between the third guide rail reinforcing plate 400 and the inner plate 1. The upper end of the second guide rail 700 is located between the second guide rail reinforcing plate 300 and the inner plate 1, and the lower end is located between the fourth guide rail reinforcing plate 500 and the inner plate 1. The first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400, and the fourth guide rail reinforcing plate 500 can strengthen the connection strength between the first guide rail 600 and the second guide rail 700 and other components of the door sheet metal assembly 100, and improve the durability of the first guide rail 600 and the second guide rail 700.

[0061] In some embodiments of the present invention, the first guide rail 600, the inner plate 1, the first guide rail reinforcing plate 200, and the inner waistline reinforcing plate 2 are connected by fasteners, which are sequentially inserted through the inner plate 1, the first guide rail 600, the first guide rail reinforcing plate 200, and the inner waistline reinforcing plate 2; and / or, the second guide rail 700, the inner plate 1, the second guide rail reinforcing plate 300, and the inner waistline reinforcing plate 2 are connected by fasteners, which are sequentially inserted through the inner plate 1, the second guide rail 700, the second guide rail reinforcing plate 300, and the inner waistline reinforcing plate 2. It is understandable that only the first guide rail 600, inner plate 1, first guide rail reinforcing plate 200, and inner waistline reinforcing plate 2 are connected by fasteners, with the fasteners sequentially passing through the inner plate 1, first guide rail 600, first guide rail reinforcing plate 200, and inner waistline reinforcing plate 2; or only the second guide rail 700, inner plate 1, second guide rail reinforcing plate 300, and inner waistline reinforcing plate 2 are connected by fasteners, with the fasteners sequentially passing through the inner plate 1, second guide rail 600, second guide rail reinforcing plate 300, and inner waistline reinforcing plate 2. The reinforcing plate 2; or the first guide rail 600, inner plate 1, first guide rail reinforcing plate 200 and inner waistline reinforcing plate 2 are connected by fasteners, with the fasteners sequentially passing through the inner plate 1, the first guide rail 600, the first guide rail reinforcing plate 200 and the inner waistline reinforcing plate 2, and the second guide rail 700, inner plate 1, second guide rail reinforcing plate 300 and inner waistline reinforcing plate 2 are connected by fasteners, with the fasteners sequentially passing through the inner plate 1, the second guide rail 700, the second guide rail reinforcing plate 300 and the inner waistline reinforcing plate 2.

[0062] In a specific example of the present invention, the first guide rail 600, the inner plate 1, the first guide rail reinforcing plate 200, and the inner waistline reinforcing plate 2 are connected by fasteners, which are sequentially inserted through the inner plate 1, the first guide rail 600, the first guide rail reinforcing plate 200, and the inner waistline reinforcing plate 2. Similarly, the second guide rail 700, the inner plate 1, the second guide rail reinforcing plate 300, and the inner waistline reinforcing plate 2 are connected by fasteners, which are sequentially inserted through the inner plate 1, the second guide rail 700, the second guide rail reinforcing plate 300, and the inner waistline reinforcing plate 2. This ensures the stability of the upper connection between the first guide rail 600 and the second guide rail 700. When the glass is closed, the enormous impact load from the reaction force of the front and rear sealing strips on the glass at the moment of closing is partially absorbed by the mounting points at the upper ends of the first guide rail 600 and the second guide rail 700, increasing the stability and reliability of the door.

[0063] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; and / or, the second guide rail reinforcing plate 300 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; and / or, the third guide rail reinforcing plate 400 is welded to the inner plate 1; and / or, the fourth guide rail reinforcing plate 500 is welded to the inner plate 1.

[0064] It is understandable that only the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; or only the second guide rail reinforcing plate 300 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; or only the third guide rail reinforcing plate 400 is welded to both the inner plate 1; or only the fourth guide rail reinforcing plate 500 is welded to both the inner plate 1; or the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the second guide rail reinforcing plate 300 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; or the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the third guide rail reinforcing plate 400 is welded to both the inner plate 1; or the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the fourth guide rail reinforcing plate 500 is welded to both the inner plate 1.

[0065] Alternatively, the second guide rail reinforcing plate 300 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the third guide rail reinforcing plate 400 may be welded to the inner plate 1; or the second guide rail reinforcing plate 300 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the fourth guide rail reinforcing plate 500 may be welded to the inner plate 1; or the third guide rail reinforcing plate 400 may be welded to the inner plate 1, and the fourth guide rail reinforcing plate 500 may be welded to the inner plate 1; or the first guide rail reinforcing plate 200 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the second guide rail reinforcing plate 300 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the third guide rail reinforcing plate 400 may be welded to the inner plate 1; or the first guide rail reinforcing plate 200 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the second guide rail reinforcing plate 300 may be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, and the fourth guide rail reinforcing plate 500 may be welded to the inner plate 1.

[0066] Alternatively, the first guide rail reinforcing plate 200 can be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, the third guide rail reinforcing plate 400 can be welded to both the inner plate 1, and the fourth guide rail reinforcing plate 500 can be welded to both the inner plate 1; or the second guide rail reinforcing plate 300 can be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, the third guide rail reinforcing plate 400 can be welded to both the inner plate 1, and the fourth guide rail reinforcing plate 500 can be welded to both the inner plate 1; or the first guide rail reinforcing plate 200 can be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, the second guide rail reinforcing plate 300 can be welded to both the inner plate 1 and the inner waistline reinforcing plate 2, the third guide rail reinforcing plate 400 can be welded to both the inner plate 1, and the fourth guide rail reinforcing plate 500 can be welded to both the inner plate 1.

[0067] In a specific example of the present invention, the first guide rail reinforcing plate 200 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; the second guide rail reinforcing plate 300 is welded to both the inner plate 1 and the inner waistline reinforcing plate 2; the third guide rail reinforcing plate 400 is welded to the inner plate 1; and the fourth guide rail reinforcing plate 500 is welded to the inner plate 1. This increases the reliability of the connections between the first guide rail reinforcing plate 200 and the second guide rail reinforcing plate 300 and the inner plate 1 and the inner waistline reinforcing plate 2, as well as the reliability of the connections between the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 and the inner plate 1. This helps to ensure the stiffness of the mounting points at the upper and lower ends of the first guide rail 600 and the second guide rail 700, and the stiffness of the mounting points at the upper ends of the first guide rail 600 and the second guide rail 700 is greater than that at the lower ends of the first guide rail 600 and the second guide rail 700, wherein the stiffness of the upper mounting points is >200 N / mm and the stiffness of the lower mounting points is >100 N / mm.

[0068] In some embodiments of the present invention, such as Figure 4As shown, the inner waistline reinforcing plate 2 has a first step portion 21 and a second step portion 22. Both the first step portion 21 and the second step portion 22 include an outwardly protruding first step surface 211 and a second step surface 212, and an inwardly protruding third step surface 213. The third step surface 213 is located between the first step surface 211 and the second step surface 212. The first guide rail reinforcing plate 200 and the second guide rail reinforcing plate 300 are respectively connected to the two third step surfaces 213. The first guide rail reinforcing plate 200 is welded to the third step surface 213 of the first step portion 21 by welding points, and the second guide rail reinforcing plate 300 is welded to the third step surface 213 of the second step portion 22 by welding points. The first step surface 211 and the second step surface 212, which are higher than the third step surface 213, can increase the rigidity of the third step surface 213 as a connecting surface, which helps to improve the rigidity of the door sheet metal assembly 100.

[0069] In a specific example of the present invention, such as Figure 2 , Figure 3 and Figure 5 As shown, the side of the upper end of the door glass closest to the door hinge is the first corner point 800, and the side of the upper end of the door glass furthest from the door hinge is the second corner point 900. Sensitivity analysis of the arrangement of the first guide rail reinforcing plate 200, the second guide rail reinforcing plate 300, the third guide rail reinforcing plate 400, and the fourth guide rail reinforcing plate 500 reveals that the stiffness of the first corner point 800 is negatively correlated with the distance L1 between the first guide rail reinforcing plate 200 and the second guide rail reinforcing plate 300, negatively correlated with the Z-direction distance H1 between the first guide rail reinforcing plate 200 and the first corner point 800, and negatively correlated with the Y-direction distance L2; the stiffness of the second corner point 900 is negatively correlated with the Z-direction distance H2 between the second guide rail reinforcing plate 300 and the second corner point 900, and negatively correlated with the Y-direction distance L3; the stiffness of both the first corner point 800 and the second corner point 900 is negatively correlated with the curvature δ of the glass.

[0070] In summary, based on the feasibility of the layout space, the Z and Y distances between the first corner point 800 of the door glass and the first guide rail reinforcement plate 200 should be minimized, as should the Z and Y distances between the second corner point 900 of the door glass and the second guide rail reinforcement plate 300. That is, the first guide rail reinforcement plate 200 should be positioned as far forward and as high as possible towards the vehicle, and the second guide rail reinforcement plate 300 should be positioned as far backward and as high as possible towards the vehicle. Simultaneously, based on the feasibility of the design and manufacturing process, the curvature δ of the glass should be minimized. Therefore, superior stiffness performance at the first corner point 800 and the second corner point 900 of the door glass can be achieved, reducing the vibration noise of the glass during door closing or raising / lowering and meeting the requirements of excellent door DTS (Dimension Technical Specifications).

[0071] In some embodiments of the present invention, such as Figure 4 As shown, the inner waistline reinforcing plate 2 has reinforcing main ribs 23 extending along the front-rear direction of the vehicle. The direction and cross-section of the reinforcing main ribs 23 have no abrupt changes, which can ensure the maximum effectiveness of force transmission.

[0072] In some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has a bent portion 501 that bends inward at its lower end; and / or, at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has flanges 502 extending inward on both sides along the vehicle's longitudinal direction. It is understood that only at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has a bent portion 501 that bends inward at its lower end; or only at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has flanges 502 extending inward on both sides along the vehicle's longitudinal direction; or at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has a bent portion 501 that bends inward at its lower end, and at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has flanges 502 extending inward on both sides along the vehicle's longitudinal direction.

[0073] In a specific example of the present invention, at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has a bent portion 501 at its lower end that bends inward, and at least one of the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 has flanges 502 extending inward on both sides along the vehicle's longitudinal direction. The third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 are welded to the bottom weld point of the inner plate 1 through the bent portion 501 at their lower ends, and the third guide rail reinforcing plate 400 and the fourth guide rail reinforcing plate 500 are welded to the inner plate 1 through the flanges 502 extending inward on both sides along the vehicle's longitudinal direction, which can increase the local stiffness and durability of the mounting surface.

[0074] In some embodiments of the present invention, such as Figure 1 The inner panel 1 has multiple reinforcing ribs 11 extending in the vertical direction, spaced apart in the front-rear direction of the vehicle. These reinforcing ribs 11 strengthen the structure of the central region of the inner panel 1, preventing low-order local modes, door shaking during operation, and other problems.

[0075] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the door sheet metal assembly 100 also includes an upper hinge reinforcement plate, and the inner waistline reinforcement plate 2 overlaps and is welded to the upper hinge reinforcement plate. The overlap between the inner waistline reinforcement plate 2 and the upper hinge reinforcement plate is adjusted according to the rigidity of the inner waistline reinforcement plate 2 and the durability of the sheet metal and weld points, thereby achieving the optimal match of weight, cost, and performance.

[0076] In this invention, the overlap between the inner waistline reinforcing plate 2 and the upper hinge reinforcing plate is 50-60mm.

[0077] In some embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the door sheet metal assembly 100 also includes: an outer waistline reinforcing plate 3, which is disposed between the inner waistline reinforcing plate 2 and the outer plate 4 and connected to the inner plate 1 and the outer plate 4. The outer waistline reinforcing plate 3 has X-direction weld points at its rear end. These X-direction weld points primarily bear shear force under the impact load of closing the door, achieving better durability compared to the tensile force of the Y-direction weld points. The outer waistline reinforcing plate 3 is connected to the inner plate 1 via X-direction weld points, and the outer waistline reinforcing plate 3 is bonded to the outer plate 4 with adhesive.

[0078] In some embodiments of the present invention, such as Figure 6 As shown, the outer waistline reinforcing plate 3 has a fourth step surface 31, a fifth step surface 32, and a sixth step surface 33 arranged sequentially and connected from top to bottom. The fourth step surface 31 is located at the outer water-cutting stop. The height difference between the fifth step surface 32 and the fourth step surface 31 can be determined according to the overlap position on both sides of the outer waistline reinforcing plate 3 and the stiffness of the outer waistline, so as to ensure the highest possible waistline stiffness. The fifth step surface 32 has weight-reducing holes, weight-reducing hole edges, and reinforcing rib structures to enhance the strength of the outer waistline reinforcing plate 3. The height of the sixth step surface 33 is determined according to the distance between the outer waistline reinforcing plate 3 and the outer plate 4.

[0079] In addition, the outer waistline reinforcement plate 3 has concealed handle mounting points, which frequently bear the opening force from the concealed handle. Therefore, it requires superior concealed handle rigidity, outer waistline rigidity, and durability to improve the quality of the door opening operation. The front end of the outer waistline reinforcement plate 3 should fully utilize the upper hinge reinforcement plate and other overlapping structures to achieve optimal joint performance.

[0080] In some embodiments of the present invention, such as Figure 2As shown, the door sheet metal assembly 100 also includes a crash beam 7. The crash beam 7 is located between the inner panel 1 and the outer panel 4 and is inclined downwards in the direction from one end of the door sheet metal assembly 100 near the door hinge to the other end. The crash beam 7 is connected to the inner panel 1 and the outer panel 4. The door sheet metal assembly 100 also has a lower hinge reinforcement plate 6, which is located near the door hinge and is welded to the inner panel 1. One end of the crash beam 7 is welded to the inner panel 1, and the other end is welded to the lower hinge reinforcement plate 6 and the inner panel 1. The crash beam 7 is glued to the outer panel 4. The crash beam 7 forms a certain angle with the X-direction mentioned above. The actual position of the crash beam 7 can be appropriately adjusted according to the amount of barrier overlap and the side impact analysis results.

[0081] In some embodiments of the present invention, the cross-section of the anti-collision beam 7 is M-shaped. This is beneficial for improving side-impact performance, dent resistance, and preventing low-order local modes from appearing on the outer plate 4.

[0082] In some embodiments of the present invention, such as Figure 2 As shown, the door sheet metal assembly 100 also includes an outer panel reinforcing plate 8. The outer panel reinforcing plate 8 is located between the inner panel 1 and the outer panel 4 and slopes downwards from one end of the door sheet metal assembly 100 near the door hinge to the other end. The outer panel reinforcing plate 8 is connected to the inner panel 1 and the outer panel 4. One end of the outer panel reinforcing plate 8 is welded to the inner panel 1, and the other end is welded to the lower hinge reinforcing plate 6 and the inner panel 1. The outer panel reinforcing plate 8 and the outer panel 4 are connected by adhesive. The necessity of adding the outer panel reinforcing plate 8 is determined based on the shape and the local stiffness and modal characteristics of the outer panel 4.

[0083] In some embodiments of the present invention, the outer panel reinforcing plate 8 has a U-shaped cross-section. This prevents the outer panel 4 from vibrating when the door is closed and also improves side impact performance.
