Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle parts, and in particular relates to a vehicle door glass guide rail structure, a vehicle door assembly and a vehicle. Background Art

[0002] Door glass guides, installed within the door sheet metal, clamp the edge of the door glass and guide its movement, making them a crucial component for enhancing the quality of door opening and closing. With the increasing demand for large vehicles with five or more seats, the market share of larger vehicles is also increasing. This increase in overall vehicle size inevitably leads to increased door sheet metal and glass dimensions, placing higher demands on the structural performance of door glass guides.

[0003] The rigidity and strength of the glass guide rails directly impact the overall performance of the door and the quality of the door's opening and closing. Increased door dimensions increase the vertical span of the glass guide rails. If the guide rails are rigid and provide a stable clamping force on the door glass, they can maintain the glass's position during closing, preventing it from shaking. To improve the rigidity and strength of glass guide rails, existing solutions primarily consider increasing the rail's cross-sectional thickness, optimizing its shape, or increasing the number of rail brackets. These designs often increase the overall weight of the glass guide rails, hindering energy efficiency and increasing production costs. Summary of the Invention

[0004] Embodiments of the present invention provide a vehicle door glass guide rail structure, a vehicle door assembly, and a vehicle, aiming to solve the problem that existing means of strengthening vehicle door glass guide rails increase the overall weight of the vehicle door glass guide rails and are difficult to control costs.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, a vehicle door glass guide rail structure is provided, comprising:

[0007] A guide rail body, and a first bracket and a second bracket respectively connected to the guide rail body on the outside, wherein the first bracket is located above the second bracket;

[0008] The inner side of the first bracket has multiple first door connection positions, and the inner side of the second bracket has multiple second door connection positions. On a plane perpendicular to the left and right directions, the connecting line of the orthographic projections of the multiple first door connection positions is defined as the first projection line, and the connecting line of the orthographic projections of the multiple second door connection positions is defined as the second projection line. The first projection line and the second projection line are parallel to each other, and the two are staggered front and back.

[0009] With reference to the first aspect, in a possible implementation manner, the first projection connecting line and the second projection connecting line are both parallel to the up-down direction.

[0010] In combination with the first aspect, in a possible implementation, the plurality of first door connection positions and the plurality of second door connection positions are all distributed along a straight line that gradually tilts inward from bottom to top;

[0011] Define the connection line of multiple first door connection positions as a first space connection line, and define the connection line of multiple second door connection positions as a second space connection line. The first space connection line intersects with the second space connection line to form a connection intersection point, and the connection intersection point is located above the first bracket.

[0012] In combination with the first aspect, in a possible implementation, the extension line of the first bracket is defined as the first extension line, the extension line of the second bracket is defined as the second extension line, the first extension line intersects with the second extension line to form an extension line intersection, and the extension line intersection is located on the outside of the vehicle door outer panel.

[0013] In some embodiments, the angle between the first extension line and the second extension line is an acute angle.

[0014] In combination with the first aspect, in a possible implementation manner, a weight-reducing hole is provided on the first bracket.

[0015] In some embodiments, the upper and lower widths of the second bracket gradually increase from the outside to the inside.

[0016] In some embodiments, a first reinforcing rib and a second reinforcing rib are provided on the second bracket, the first reinforcing rib extends along the upper edge of the second bracket, the second reinforcing rib extends along the lower edge of the second bracket, and the first reinforcing rib and the second reinforcing rib are cross-arranged.

[0017] In the solution shown in the embodiment of the present application, the guide rail body is mainly connected to the door inner panel via the first bracket and the second bracket. At the moment of door closing, the inertia of the door glass generates an outward squeezing force on the guide rail body. As the door glass and the guide rail body interact, the door glass generates a reciprocating force on the guide rail body in the inward and outward directions, thereby generating vibration. The vibration energy of the door glass is transmitted to the door inner panel via the guide rail body, the first bracket and the second bracket. Based on this scenario, compared with the prior art, the solution shown in the embodiment of the present application has the following beneficial effects:

[0018] 1) The first bracket has multiple first door connection positions, and the second bracket has multiple second door connection positions, so that the first bracket, the second bracket and the door inner panel have a strong bonding strength, which improves the assembly strength between the door glass guide rail structure and the door inner panel, and can attenuate the vibration energy transmitted to the door inner panel to a certain extent, thereby improving the problem of the door glass driving the door inner panel to vibrate.

[0019] 2) Since the first projection line and the second projection line are parallel to each other and are staggered front to back, the force transmission paths formed by the first bracket and the second bracket have different angles and directions. The door glass guide rail structure forms a richer force transmission path between the door glass and the door inner panel, and the shaking energy of the door glass can be more effectively decomposed, thereby more effectively attenuating the shaking energy of the door glass.

[0020] 3) On a plane perpendicular to the long axis of the guide rail body, the guide rail body, the first bracket, the second bracket and the door inner panel can be enclosed to form a triangular structure, which has better rigidity and structural strength after assembly.

[0021] 4) The guide rail body, the first bracket, and the second bracket form a lever structure between the door glass and the door inner panel, wherein one of the first bracket and the second bracket can form a fulcrum, the door glass can serve as a resistance source, and the door inner panel serves as a power source. Since the first projection line and the second projection line are parallel to each other and are staggered front to back, the power arm and the resistance arm of the lever structure are not zero, and the first bracket and the second bracket are subjected to the same force direction. Based on this, the door inner panel can hinder the shaking of the door glass with a relatively small force, effectively attenuating the amplitude of the door glass shaking. At the same time, the pulling effect of the door glass on the door inner panel is also reduced due to the reduction in the vibration amplitude of the door glass, ultimately attenuating the shaking energy of the door glass, effectively improving the problem of door glass shaking.

[0022] 5) The improvement of the door glass guide rail structure mainly lies in the improvement of the connection position of the first bracket and the second bracket. There is no need to make more complicated improvements to the structure of the guide rail body, nor is there a need to use too many brackets to achieve the installation of the guide rail body and the door inner panel. The overall door glass guide rail structure uses less material and is less difficult to design and manufacture. Without increasing the weight and cost of the door glass guide rail structure, it can effectively strengthen its own structure and effectively improve the problem of door glass shaking.

[0023] In a second aspect, an embodiment of the present invention further provides a vehicle door assembly, comprising a vehicle door inner panel and the above-mentioned vehicle door glass guide rail structure, wherein the vehicle door glass guide rail structure is arranged on the inner side of the vehicle door inner panel, and the inner side of the first bracket and the inner side of the second bracket are respectively connected to the outer panel surface of the vehicle door inner panel.

[0024] Compared with the prior art, the solution shown in the embodiment of the present application effectively improves the shaking problem of the door glass when closing the door by adopting the above-mentioned door glass guide rail structure, thereby improving the user experience without basically increasing the production cost.

[0025] In a third aspect, an embodiment of the present invention further provides a vehicle comprising the above-mentioned door assembly.

[0026] Compared with the prior art, the solution shown in the embodiment of the present application improves the user experience when closing the door by adopting the above-mentioned door assembly, while the production cost is effectively controlled, which is conducive to improving the market competitiveness of the entire vehicle.

[0041] Please also refer to Figures 1 to 5 The vehicle door glass guide rail structure provided by the present invention is now described. The vehicle door glass guide rail structure includes a guide rail body 1, and a first bracket 2 and a second bracket 3 respectively connected to the guide rail body 1 on the outside. The first bracket 2 is located above the second bracket 3; the inner side of the first bracket 2 has a plurality of first vehicle door connection positions 201, and the inner side of the second bracket 3 has a plurality of second vehicle door connection positions 301. On a plane perpendicular to the left and right directions, the connecting line of the orthographic projections of the plurality of first vehicle door connection positions 201 is defined as the first projection line 202, and the connecting line of the orthographic projections of the plurality of second vehicle door connection positions 301 is defined as the second projection line 302. The first projection line 202 and the second projection line 302 are parallel to each other and are staggered in front and back. Among them, the first projection line 202 can be located before the second projection line 302 or after the second projection line 302.

[0042] In this embodiment, the first door connection point 201 refers to the point where the first bracket 2 connects to the door inner panel 4, and the second door connection point 301 refers to the point where the second bracket 3 connects to the door inner panel 4. Since there are multiple first door connection points 201 and second door connection points 301, respectively, the reliability of the connection with the door inner panel 4 can be guaranteed. The connection methods of the first door connection point 201 and the door inner panel 4, and the connection methods of the second bracket 3 and the door inner panel 4 include but are not limited to welding, connection via threaded fasteners after bonding, etc.

[0043] It should also be noted that, in addition to the first bracket 2 and the second bracket 3, a third bracket, a fourth bracket, and so on may be provided between the first bracket 2 and the second bracket 3, below the second bracket 3, or above the first bracket 2. There is no specific limit on the number of brackets provided. The third bracket, the fourth bracket, and other bracket structures also have connection points, such as third and fourth door connection points, on the inner side of the door inner panel 4 that are connected to the door inner panel 4, similarly distributed to the first door connection points 201 and the second door connection points 301. These points are not listed here one by one.

[0044] In this embodiment, at least two first door connection positions 201 are provided on the same first bracket 2, and at least two second door connection positions 301 are provided on the same second bracket 3. The number of connection positions is not limited here and can be selectively set according to actual connection requirements. This embodiment exemplifies an implementation in which two first door connection positions 201 are provided on the same first bracket 2, and two second door connection positions 301 are provided on the same second bracket 3.

[0045] The present embodiment provides a door glass guide rail structure in which the guide rail body 1 is connected to the door inner panel 4 primarily through the first bracket 2 and the second bracket 3. At the moment of door closing, the inertia of the door glass exerts an outward squeezing force on the guide rail body 1. As the door glass interacts with the guide rail body 1, the door glass exerts a reciprocating force on the guide rail body 1 in the inward and outward directions, thereby generating vibration. The vibration energy of the door glass is transmitted to the door inner panel 4 via the guide rail body 1, the first bracket 2, and the second bracket 3. Based on this scenario, the solution shown in this embodiment has the following beneficial effects compared with the prior art:

[0046] 1) The first bracket 2 has a plurality of first door connection positions 201, and the second bracket 3 has a plurality of second door connection positions 301, so that the first bracket 2, the second bracket 3 and the door inner panel 4 have a strong bonding strength, thereby improving the assembly strength between the door glass guide rail structure and the door inner panel 4, and can attenuate the vibration energy transmitted to the door inner panel 4 to a certain extent, thereby improving the problem of the door glass driving the door inner panel 4 to vibrate.

[0047] 2) Since the first projection line 202 and the second projection line 302 are parallel to each other and are staggered front to back, the force transmission paths formed by the first bracket 2 and the second bracket 3 have different angles and different force transmission directions. The door glass guide rail structure forms a richer force transmission path between the door glass and the door inner panel 4, and the shaking energy of the door glass can be more decomposed, thereby more effectively attenuating the shaking energy of the door glass.

[0048] 3) On a plane perpendicular to the long axis of the guide rail body 1, the guide rail body 1, the first bracket 2, the second bracket 3 and the door inner panel 4 can be enclosed to form a triangular structure, which has better rigidity and structural strength after assembly.

[0049] 4) The guide rail body 1, the first bracket 2 and the second bracket 3 form a lever structure between the door glass and the door inner panel 4, wherein one of the first bracket 2 and the second bracket 3 can form a fulcrum, the door glass can be used as a resistance source, and the door inner panel 4 as a power source. Since the first projection line 202 and the second projection line 302 are parallel to each other and are staggered front to back, the power arm and the resistance arm of the lever structure are not zero, and the first bracket 2 and the second bracket 3 are subjected to the same force direction. Based on this, the door inner panel 4 can hinder the shaking of the door glass with a relatively small force, and effectively attenuate the shaking amplitude of the door glass. At the same time, the pulling effect of the door glass on the door inner panel 4 is also reduced due to the reduction in the vibration amplitude of the door glass, which ultimately attenuates the shaking energy of the door glass, effectively improving the problem of door glass shaking.

[0050] 5) The improvement of the door glass guide rail structure mainly lies in the improvement of the connection position of the first bracket 2 and the second bracket 3. There is no need to make more complicated improvements to the structure of the guide rail body 1, nor is there a need to use too many brackets to achieve the installation of the guide rail body 1 and the door inner panel 4. The overall door glass guide rail structure uses less material and is less difficult to design and manufacture. Without increasing the weight and cost of the door glass guide rail structure, it can effectively strengthen its own structure and effectively improve the problem of door glass shaking.

[0051] In addition, some embodiments exemplify a design in which the guide rail body 1 is gradually tilted backward from bottom to top. This design is mainly applicable to the front door of a vehicle. Specifically, the guide rail body 1 is located at the front of the vehicle door and clamps and guides the front edge of the front door glass. In order to adapt to the tilted shape of the front edge of the vehicle door glass, it is designed as a tilted structure. The inventors have discovered that this tilted design is also a significant adverse factor affecting the rigidity and strength of the vehicle door glass guide rail itself. In this embodiment, the first projection line 202 and the second projection line 302 are parallel to each other, and the two are staggered front to back, so that the first projection line 202 and the second projection are both set at an angle to the long axis of the guide rail body 1, forming a principle similar to triangle reinforcement, enhancing the load-bearing capacity in the direction perpendicular to the inner and outer directions, and promoting the structural strength and rigidity of the vehicle door glass guide rail structure.

[0052] It should be noted that the vehicle door glass guide rail structure of this embodiment is applicable not only to front doors, but also to other vehicle door structures requiring similar reinforcement. Furthermore, the guide rail body 1 may be a member extending vertically or tilted, without limitation. This embodiment exemplifies the vehicle door glass guide rail structure and door inner panel corresponding to the right front door; other embodiments are not listed here.

[0053] Based on the inclined design of the guide rail body 1, see Figures 1 to 5 To maximize the distance between the first and second projection lines, the second bracket 3 is located at the bottom of the guide rail body 1, and the first bracket 2 is positioned as close to the window frame 410 as possible. More specifically, to provide more effective guidance for the door glass, the upper portion of the guide rail body 1 extends to the area corresponding to the window frame 410. This area can be clamped and fixed by the sheet metal structures on both sides of the window frame 410, thereby achieving effective position control.

[0054] In some specific distribution embodiments of the first projection line 202 and the second projection line 302, the first projection line 202 and the second projection line 302 are parallel to the up-down direction, such as Figure 5This arrangement ensures a good degree of overlap between the first door connection locations 201 and the second door connection locations 301 in the front-to-back direction. During the raising and lowering of the door glass, the friction force generated between the door glass and the guide rail body 1 is primarily in the vertical direction. The overlapping design of the connection locations effectively enhances the load-bearing capacity of the first bracket 2 and the second bracket 3 in the vertical direction, thereby enhancing their structural stability.

[0055] In some embodiments, in order to further enhance the structural stability of the entire door glass guide rail structure, see Figures 2 to 5 , multiple first door connection positions 201 and multiple second door connection positions 301 are distributed along a straight line that gradually tilts inward from bottom to top; the connecting line of multiple first door connection positions 201 is defined as the first space connection line 203, and the connecting line of multiple second door connection positions 301 is defined as the second space connection line 303, the first space connection line 203 and the second space connection line 303 intersect to form a connection intersection point 5, and the connection intersection point 5 is located above the first bracket 2.

[0056] More specifically, second bracket 3 is positioned adjacent to the vehicle's waistline. The waistline refers to the two decorative strips on either side of the vehicle's doors. These strips serve a decorative purpose and are one of the most important defining features of a vehicle. Together with the hood line, roofline, and trunk line, they define the vehicle's overall contours. In waistline design, the connection between the waistline and the front and rear lights, as well as the integration of the front and rear lights within the overall surface, must be consistent. Therefore, waistline design is a key factor in the vehicle's exterior character. The waistline also serves as a reinforcement for the vehicle's body and doors, providing a cushioning effect and withstanding impact forces in the event of a collision. This demonstrates the relatively high structural strength of the waistline region. In this embodiment, the force transmitted to the door inner panel 4 by the first bracket 2 has a component along the first spatial line 203, and the force transmitted to the door inner panel 4 by the second bracket 3 has a component along the second spatial line 303. Since the intersection 5 of the lines is located above the first bracket 2, the components of the forces of the two brackets will converge toward the area where the second bracket 3 is located, thereby ensuring that the force acting on the guide rail body 1 can be accurately transmitted to the waistline position, thereby enhancing the structural stability of the overall door glass guide rail structure.

[0057] See Figure 6 and Figure 7In some embodiments, the first bracket 2 includes a first bracket 2 main body, a first inner flange 220 and a first outer flange 230, the first outer flange 230 is fitly connected to the guide rail main body 1, the first inner flange 220 is arranged on the inner side of the first bracket 2 main body, and is fitly connected to the door inner panel 4; the second bracket 3 includes a second bracket 3 main body, a second inner flange 320 and a second outer flange 330, the second outer flange 330 is fitly connected to the guide rail main body 1, the second inner flange 320 is arranged on the inner side of the second bracket 3 main body, and is fitly connected to the door inner panel 4; wherein, the first door connection position 201 is arranged on the first inner flange 220, and the second door connection position 301 is arranged on the second inner flange 320.

[0058] More specifically, to enhance the structural strength of the second bracket 3, the second inner flange 320 and the second outer flange 330 extend in opposite directions. The guide rail body 1 has a guide groove that opens rearward, and the first outer flange 230 can be in close contact with the front side or inner side of the guide rail body 1, and the second outer flange 330 can be in close contact with the front side or inner side of the guide rail body 1.

[0059] More specifically, the main bodies of the first bracket 2 and the second bracket 3 are both plate-shaped components. They can be integrally formed through processes such as stamping, making manufacturing easier and eliminating seams, resulting in higher structural strength. Furthermore, the structures of the first and second brackets 2 and 3 are relatively thin and lightweight, using less material, better meeting the design requirements of miniaturization and lightweighting. To further enhance the structural strength of the first and second brackets 2 and 3, a first reinforcing flange is provided on the edge of the main body of the first bracket 2, and a second reinforcing flange is provided on the edge of the main body of the second bracket 3.

[0060] More specifically, to accommodate the tilted arrangement of the first spatial connection line 203 and the second spatial connection line 303, the door inner panel 4 is provided with a first boss 420 that mates with the first inner flange 220, and a second boss 430 that mates with the second inner flange 320. Taking the arrangement of the first spatial connection line 203 as an example, the tilted arrangement of the first spatial connection line 203 can be such that the first inner flange 220 is substantially flat, with the plurality of first door connection points 201 disposed on the flat first inner flange 220. In this case, the first boss 420 has a substantially flat mate surface. Taking the arrangement of the second spatial connection line 303 as an example, the tilted arrangement of the second spatial connection line 303 can be such that the second inner flange 320 is curved, with the plurality of second door connection points 301 disposed on the curved second inner flange 320. In this case, the second boss has a curved mate surface. It should be understood that the specific configuration of the inner flange is arranged in accordance with the shape of the boss, and the specific configuration of the boss is mainly related to the specific stress conditions and component assembly conditions of the vehicle door inner panel 4. Other examples are not listed here one by one.

[0061] In some embodiments, see Figure 2 、 Figure 6 and Figure 7 The extension line of the first bracket 2 is defined as the first extension line 204, and the extension line of the second bracket 3 is defined as the second extension line 304. The first extension line 204 and the second extension line 304 intersect to form an extension line intersection point, which is located on the outside of the door outer panel. During the closing process of the vehicle door, the door glass primarily shakes in the inward and outward directions. The first bracket 2 and the second bracket 3 form a triangular support structure in space, enhancing the load-bearing strength in the inward and outward directions, and maximally attenuating and absorbing the shaking energy of the door glass in this direction, thereby improving the overall structural stability of the door glass guide rail structure and preventing shaking of the guide rail body 1.

[0062] Based on the above embodiment, the angle between the first extension line and the second extension line is an acute angle. In a specific implementation, the angle between the first extension line and the second extension line is 55° to 65° (eg, 58°, 60°, 62°).

[0063] Optionally, the first extension line, the second extension line, and a connecting line between the inner side of the first bracket 2 and the inner side of the second bracket 3 form an equilateral triangle.

[0064] In some more specific embodiments, the second extension line gradually tilts downward from the outside to the inside, and the second extension line is set at an angle to the left and right directions (for example, gradually tilted backward from the outside to the inside); the first extension line extends in the outward direction, and the first extension line is set at an angle to the left and right directions (for example, gradually tilted backward from the outside to the inside).

[0065] In some specific embodiments of the second bracket 3, see FIG. Figure 2 、 Figure 4 and Figure 7 The upper and lower widths of the second bracket 3 gradually increase from the outside to the inside, so that the second bracket 3 as a whole forms a trapezoidal structure with a narrow outside and a wide inside, and the second bracket 3 itself has a higher structural strength.

[0066] Based on the above embodiments, see Figure 4 and Figure 7 The second bracket 3 is provided with a first reinforcing rib 350 and a second reinforcing rib 360. The first reinforcing rib 350 extends along the upper edge of the second bracket 3, and the second reinforcing rib 360 extends along the lower edge of the second bracket 3. The first reinforcing rib 350 and the second reinforcing rib 360 are arranged crosswise. The first reinforcing rib 350 reinforces the upper edge of the second bracket 3, and the second reinforcing rib 360 reinforces the lower edge of the second bracket 3. In addition, due to the cross design of the first reinforcing rib 350 and the second reinforcing rib 360, the first reinforcing rib 350 and the second reinforcing rib 360 form an integrated reinforcing structure, which has a better reinforcing effect.

[0067] In specific implementation, the first reinforcing rib 350 and the second reinforcing rib 360 can be designed as a middle cross design (not shown in the figure), or can be designed as an end cross design (such as Figure 4 and Figure 7 shown.)

[0068] In some embodiments, see Figure 3 and Figure 6 To reduce the weight of the first bracket 2, a lightening hole 205 is provided. To prevent stress concentration and tearing in the area of ​​the lightening hole 205, the inner wall of the lightening hole 205 has no sharp corners and a smooth transition. Specifically, the lightening hole 205 can be a circular hole, an elliptical hole, an oblong hole, or other hole, depending on the overall design requirements of the first bracket 2.

[0069] Based on the above embodiments, see Figure 3 and Figure 4 The first bracket 2 is provided with a reinforcing boss, on which a weight-reducing hole 205 is provided. It is understood that the provision of the weight-reducing hole 205 will weaken the structural strength of the opening area. To ensure the structural strength of the opening area, the reinforcing boss is provided to strengthen it, thereby maximizing the opening area of ​​the weight-reducing hole 205. Based on the first bracket 2 comprising a first bracket 2 main body, a first inner flange 220, and a first outer flange 230, the reinforcing boss is provided on the first bracket 2 main body, with the outer edge of the reinforcing boss extending to the first outer flange 230 and the inner edge extending to the first inner flange 220.
