[0028] Please also read Figures 1 to 8 Now, the vehicle door window frame structure and the vehicle provided by the utility model are described. The vehicle door window frame structure comprises a vehicle door inner panel 1, a window frame reinforcement plate 2 and an outer window frame reinforcement plate 3. The window frame reinforcement plate 2 is a hollow tubular member and extends in a ring shape along the circumference of the window frame. The window frame reinforcement plate 2 is connected to the side of the vehicle door inner panel 1 away from the center axis of the vehicle body. The vehicle door inner panel 1 is provided with a connecting flange bent toward the outside of the vehicle body and connected to the window frame reinforcement plate 2. The lower part of the window frame reinforcement plate 2 is connected to the hinge reinforcement plate 4 and the door lock reinforcement plate 5 respectively. The outer window frame reinforcement plate 3 is connected between the hinge reinforcement plate 4 and the door lock reinforcement plate 5. The outer window frame reinforcement plate 3 and the window frame reinforcement plate 2 form a gap for accommodating the vehicle window glass.

[0029] Compared with the prior art, the vehicle door window frame structure provided in the present embodiment has a window frame reinforcement plate 2 that adopts a hollow tubular structure. The vehicle door inner panel 1 is connected to the window frame reinforcement plate 2 and also increases the connection area with the window frame reinforcement plate 2 by means of a connecting flange. The lower part of the window frame reinforcement plate 2 is respectively connected to the hinge reinforcement plate 4 and the door lock reinforcement plate 5 to form a force transmission channel from top to bottom, thereby enhancing the force transmission continuity of the window frame position. The outer window frame reinforcement plate 3 connected between the hinge reinforcement plate 4 and the door lock reinforcement plate 5 can assist the window frame reinforcement plate 2 in improving the structural rigidity of the window frame, thereby ensuring the overall structural performance of the vehicle door.

[0030] In this embodiment, the window frame reinforcement plate 2 adopts a hollow tubular structure, and extends along the circumference of the window frame and encloses a closed ring. This structural form effectively improves the structural strength of the window frame reinforcement plate 2, so that even with a smaller cross-sectional size, it can have greater strength and rigidity, meeting the requirements of the window frame position regarding the field of view.

[0031] On this basis, the side wall of the door inner panel 1 is connected to the side wall of the window frame reinforcement plate 2, and the connection area between the door inner panel 1 and the window frame reinforcement plate 2 is increased by a connecting flange. The connecting flange is located on the inner circumferential wall of the annular structure surrounded by the window frame reinforcement plate 2. The connecting flange can be set along the inner circumferential wall for a whole circle, or it can be set for a part, so as to increase the bonding area between the window frame reinforcement plate 2 and the door inner panel 1, meet the bonding size requirements, and ensure the connection strength of the structure.

[0032] The lower front area of ​​the window frame reinforcement plate 2 is connected to the hinge reinforcement plate 4, and the lower rear area of ​​the window frame reinforcement plate 2 is connected to the door lock reinforcement plate 5. This arrangement can form a top-down force transmission channel, thereby enhancing the force transmission continuity of the window frame position.

[0033] On this basis, combined with the structure that the front and rear ends of the outer window frame reinforcement plate 3 are respectively connected to the hinge reinforcement plate 4 and the door lock reinforcement plate 5, the above components can form a space that is through from top to bottom for the window glass to pass through, and the above components are enclosed in a ring shape with the main axis arranged in the up and down direction, which can improve the overall structural strength of the window frame position and ensure the safety of the structure. At the same time, when the door is in the closed state, the window frame can have sufficient rigidity and strength, which can effectively offset the rebound load of the sealing strip, ensure the appearance difference requirements between the door inner panel 1 and the body side, and help to improve the exquisite appearance of the vehicle.

[0034] In some possible implementations, the above-mentioned characteristic window frame reinforcement plate 2 is adopted as follows Figure 6 See the structure shown. Figure 6 The window frame reinforcement plate 2 includes an integrally formed lower bottom tube 21, an upper top tube 22 and two side vertical tubes 23, and the connecting flange includes a lower flange 12 connected to the top wall of the lower bottom tube 21, and the top wall of the lower bottom tube 21 extends obliquely upward toward the outer side of the vehicle body.

[0035] In this embodiment, the window frame reinforcement plate 2 adopts a structure in which a lower bottom tube 21, an upper top tube 22 and two side bottom tubes are integrally formed. The above components can be enclosed into a quadrilateral of different sizes, and the corresponding size can be selected according to the characteristics of the vehicle model. It should be noted that for the front door position of the vehicle, the upper top tube 22 and the front side vertical tube 23 can adopt an integral structure extending in an arc shape, and the window frame reinforcement plate 2 forms a frame structure that is approximately triangular.

[0036] The lower flange 12 on the door inner panel 1 extends to a side away from the center axis of the vehicle body and is connected to the top wall of the lower bottom tube 21. The top wall of the lower bottom tube 21 extends obliquely upward toward the outer side of the vehicle body, which is convenient for reducing the bending angle of the lower flange 12, achieving effective bonding between the lower flange 12 and the top wall of the lower bottom tube 21, meeting the bonding size requirements, and improving the reliability of the connection.

[0037] In some embodiments, the top pipe 22 of the above features can be used as follows Figure 7 See the structure shown. Figure 7 The top wall of the upper top tube 22 extends obliquely upward toward the outside of the vehicle body, and the upper edge of the door inner panel 1 is provided with an upper flange 11 connected to the top wall of the upper top tube 22. On the basis of using the lower flange 12 to connect with the top wall of the lower bottom tube 21, an upper flange 11 is also provided on the door inner panel 1, and the upper flange 11 can be effectively bonded to the bottom wall of the upper top tube 22, thereby increasing the bonding area between the door inner panel 1 and the window frame reinforcement plate 2.

[0038] Similarly, the upper flange 11 extends obliquely upward toward the outer side of the vehicle body, which is convenient for reducing the bending angle of the upper flange 11, achieving effective bonding between the upper flange 11 and the top wall of the lower top tube, meeting the bonding size requirements, and improving the reliability of the connection.

[0039] In some possible implementations, the above-mentioned characteristic window frame reinforcement plate 2 is adopted as follows Figure 1 , Figure 3 , Figures 4 to 5 See the structure shown. Figure 1 , Figure 3 , Figures 4 to 5 The window frame reinforcement plate 2 is integrally formed with a reinforcement protrusion 24 that protrudes toward the outside of the vehicle body. The reinforcement protrusion 24 is located at the front of the window frame reinforcement plate 2. The reinforcement protrusion 24 is horizontally corresponding to and connected to the exterior rearview mirror mounting plate 6.

[0040] In the present embodiment, a reinforcing protrusion 24 is further provided for the window frame reinforcement plate 2 on the front door of the vehicle. The reinforcing protrusion 24 is located at a position of the window frame reinforcement plate 2 close to the exterior rearview mirror, that is, located at the front outer side of the window frame reinforcement plate 2. The reinforcing boss protrudes toward the outer side of the vehicle body and can correspond horizontally to the exterior rearview mirror mounting plate 6, so as to realize reliable installation of the exterior rearview mirror mounting plate 6, ensure the connection strength of the structure, improve the structural strength of this part of the window frame, form a force transmission channel arranged along the exterior rearview mirror reinforcement plate and the lower bottom tube 21 and extending in the front-to-back direction, so that a plurality of force transmission channels are formed in the window frame part from top to bottom and from front to back, thereby ensuring the continuity of force transmission of the door window frame, enhancing the rigidity of the front corner of the window frame and the mounting position of the exterior rearview mirror, and improving the reliability of the structural installation.

[0041] In some possible implementations, the above-mentioned characteristic window frame reinforcement plate 2 is adopted as follows Figures 1 to 2 See the structure shown. Figures 1 to 2The front side of the window frame reinforcement plate 2 is integrally formed with a front extension portion 25 connected to the door inner panel 1, or the rear side of the window frame reinforcement plate 2 is integrally formed with a rear extension portion 26 connected to the door inner panel 1, or the front side of the window frame reinforcement plate 2 is integrally formed with the front extension portion 25 and the rear side is integrally formed with the rear extension portion 26, and the front extension portion 25 and the rear extension portion 26 are both located on the side of the door inner panel 1 away from the center axis of the vehicle body.

[0042] In this embodiment, the front extension 25 is connected to the front side of the window frame reinforcement plate 2, and this structure is suitable for the window frame reinforcement plate 2 of the vehicle rear door. The front extension 25 can be reliably connected to the side wall of the door inner panel 1, further enhancing the structural strength of the window frame reinforcement plate 2, while also increasing the connection area between the window frame reinforcement plate 2 and the door inner panel 1, ensuring the reliability of the structural connection. On this basis, a rear extension 26 can also be provided on the window frame reinforcement plate 2 of the vehicle front door or the vehicle rear door, and connected to the door inner panel 1 through the rear extension 26.

[0043] It should be noted that, depending on the position and structure of the window frame reinforcement plate 2, the front extension portion 25 or the rear extension portion 26 can be provided separately, or the front extension portion 25 and the rear extension portion 26 can be provided simultaneously. The front extension portion 25 and the rear extension portion 26 are respectively provided along the extension direction of the side vertical pipe 23, which helps to enhance the structural strength of the window frame reinforcement plate 2.

[0044] Based on the above structure, see Figures 4 to 6 The rear part of the window frame reinforcement plate 2 has a rear connection part 27 extending downward, one side wall of the rear connection part 27 is connected to the door inner panel 1, and the other side wall of the rear connection part 27 is connected to the door lock reinforcement plate 5. The rear connection part 27 is located below the rear part of the window frame reinforcement plate 2, that is, below the side stand pipe 23, and the rear connection part 27 can be reliably connected to the door lock reinforcement plate 5. The side stand pipe 23, the rear connection part 27 and the door lock reinforcement plate 5 can form a force transmission channel from top to bottom, realize the continuity of force transmission at the window frame position, and meet the structural strength of the rear part of the window frame.

[0045] In some embodiments, the above-mentioned characteristic rear connecting portion 27 can be adopted as follows Figures 4 to 6 See the structure shown. Figures 4 to 6 The side wall of the rear connecting portion 27 away from the door inner panel 1 is inclined from top to bottom toward the side close to the door inner panel 1, and the cross section of the rear connecting portion 27 is a triangle. The rear connecting portion 27 adopts a nearly triangular structure with a wide top and a narrow bottom. The stability of the triangle is used to further improve the connection effect with the door lock reinforcement plate 5, and at the same time, sufficient avoidance space is provided for the installation of the door lock reinforcement plate 5.

[0046] In some possible implementations, the above-mentioned characteristic window frame reinforcement plate 2 is adopted as follows Figure 6 See the structure shown. Figure 6The front part of the window frame reinforcement plate 2 has a front connecting portion 28 extending downward, one side wall of the front connecting portion 28 is connected to the door inner panel 1, and the other side wall of the front connecting portion 28 is connected to the hinge reinforcement plate 4. The front connecting portion 28 is used to connect with the hinge reinforcement plate 4, and the thickness of the front connecting portion 28 in the left-right direction is less than the thickness of the lower bottom tube 21 in the corresponding direction, which provides an avoidance space for the installation of the hinge reinforcement plate 4 and facilitates the installation operation of the hinge reinforcement plate 4.

[0047] In some possible implementations, the door inner panel 1 and the window frame reinforcement panel 2 are both carbon fiber components, and the door inner panel 1 and the window frame reinforcement panel 2 are bonded together. The carbon fiber door inner panel 1 and the window frame reinforcement panel 2 have excellent properties such as light weight, high strength, and high rigidity. Compared with traditional materials, this material can reduce the weight of components by about 30% while ensuring strength and rigidity.

[0048] In addition, carbon fiber components are also characterized by high hardness and good elasticity, which can better absorb energy and achieve good shock absorption performance. They can reduce body vibration when driving at high speeds, improve vehicle stability and driving smoothness, and enhance the riding experience of passengers.

[0049] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, which includes a vehicle door window frame structure. The window frame reinforcement plate 2 of the above vehicle adopts a hollow tubular structure, and the door inner panel 1 is connected to the window frame reinforcement plate 2, and the connection area with the window frame reinforcement plate 2 is increased by means of a connection flange to ensure the connection strength of the structure.
