[0029] With the continuous development of modern automobiles, in order to improve the driver's and passengers' visibility and cater to a more modern appearance, some door and window frame structures have become narrower and flatter. This has led to insufficient rigidity of the door and window frame structure and reduced vehicle modal performance.

[0030] Therefore, it is necessary to optimize the design of this door and window frame structure to meet the requirements of a narrow and flat door shape while improving its rigidity and vehicle modal performance.

[0031] To address the related technical problems, this application provides a car door window frame structure, see [link to relevant documentation]. Figure 1 , Figure 1 This is a structural diagram of the door and window frame structure provided in this application.

[0032] The car door window frame includes a door window edge reinforcing plate 10, a door inner panel 20, and a plastic support member 30. The door window edge reinforcing plate 10 covers the door inner panel 20 to form a window frame energy-absorbing cavity 40. The plastic support member 30 is disposed within the window frame energy-absorbing cavity 40 and is bonded and fixed to at least one of the door window edge reinforcing plate 10 and the door inner panel 20. Through the above embodiment, the plastic support member 30 is provided within the window frame energy-absorbing cavity 40 to improve the rigidity of the car door window frame structure 1. The plastic support member 30 is bonded to the door window edge reinforcing plate 10 and the door inner panel 20 within the window frame energy-absorbing cavity 40, which reduces installation difficulty. Simultaneously, the plastic support member 30 is easy to design and manufacture into various shapes, allowing it to improve the rigidity of the car door window frame structure 1 while adapting to the shapes of the door window edge reinforcing plate 10 and the door inner panel 20; the plastic reinforcing member also helps to reduce the weight of the car door window frame structure 1.

[0033] The door window edge reinforcement plate 10 and the inner door panel 20 typically feature flanges. These flanges connect and form a window frame energy-absorbing cavity 40, which collapses and absorbs energy during a collision. A plastic support member 30 is located between the door window edge reinforcement plate 10 and the inner door panel 20. It connects to the surfaces of the flanged portions of the door window edge reinforcement plate 10 and the inner door panel 20 without affecting their connection. Because the plastic support member 30 is made of plastic, even if its size is small due to the narrow window frame energy-absorbing cavity 40, it can be designed and manufactured in various shapes to better fit and connect with the shapes of the door window edge reinforcement plate 10 and the inner door panel 20.

[0034] The plastic support component 30 is bonded and fixed to the door and window frame structure 1 using automotive-grade adhesives, such as 3MDP810 (methacrylate) adhesive, two-component epoxy resin adhesive, and polyurethane adhesive. The plastic support component 30 can be bonded to the door and window edge reinforcement plate 10 or the door inner panel 20 on one side, or it can be bonded to both the door inner panel 20 and the door and window edge reinforcement plate 10 simultaneously on both sides. The former method uses less space in the window frame energy-absorbing cavity 40, but the connection strength of the plastic support component 30 is not as good as the latter. The latter method provides a higher connection strength between the plastic support component 30 and the door and window edge reinforcement plate 10 and the door inner panel 20, but the thickness of the plastic support component 30 is slightly reduced. Preferably, the plastic support component 30 is simultaneously connected to the door and window edge reinforcement plate 10 and the door inner panel 20 on both sides.

[0035] See also Figure 2 and Figure 3 , Figure 2 This is a first-view structural schematic diagram of the plastic support component provided in this application. Figure 3 This is a second-view structural schematic diagram of the plastic support component provided in this application.

[0036] The window frame energy-absorbing cavity 40 includes a horizontal frame energy-absorbing cavity 410 and a vertical frame energy-absorbing cavity 420 that are bent and connected. The plastic support member 30 includes a horizontal frame portion 310 and a vertical frame portion 320 that are bent and connected. The horizontal frame portion 310 is located in the horizontal frame energy-absorbing cavity 410, and the vertical frame portion 320 is located in the vertical frame energy-absorbing cavity 420. The door window edge reinforcing plate 10 and the door inner panel 20 both have a window edge portion and a vertical window frame portion. The window edge portion is located at the lower edge of the window frame and extends along the length direction of the vehicle. The vertical window frame portion is bent and connected to the window edge portion and extends along the height direction of the vehicle. The window edge portion and the vertical window frame portion together form an opening for installing the window glass. The horizontal frame energy-absorbing cavity 410 is formed by covering the window edge portion of the door window edge reinforcing plate 10 and the door inner panel 20, and the vertical frame energy-absorbing cavity 420 is formed by covering the vertical window frame portion of the door window edge reinforcing plate 10 and the door inner panel 20. The horizontal frame portion 310 extends within the horizontal frame energy-absorbing cavity 410 to strengthen the window sill portion, and the vertical frame portion 320 extends within the vertical frame energy-absorbing cavity 420 to strengthen the vertical window frame portion. Since the vertical window frame portion is particularly narrow and flat, the length of the vertical frame portion 320 can be set to be larger to effectively strengthen the vertical window frame portion; the extension lengths of the horizontal frame portion 310 and the vertical frame portion 320 within the horizontal frame energy-absorbing cavity 410 and the vertical frame energy-absorbing cavity 420 can be adjusted as needed.

[0037] The plastic support member 30 has a first plane 330 and a second plane 340 that are relatively opposed to each other. The first plane 330 has a first connecting surface 3310 protruding from the first plane 330, and the second plane 340 has a second connecting surface 3410 protruding from the second plane 340. The first connecting surface 3310 is bonded to the door window edge reinforcing plate 10, and the second connecting surface 3410 is bonded to the inner door panel 20. On the one hand, the fact that the first connecting surface 3310 and the second connecting surface 3410 protrude from the first plane 330 and the second plane 340 respectively allows the plastic support member 30 to bend and extend in different directions, thereby increasing the rigidity of the plastic support member 30. On the other hand, the plastic support member 30 is connected to the door and window frame structure 1 via the first connecting surface 3310 and the second connecting surface 3410. The first connecting surface 3310 and the second connecting surface 3410 occupy part of the surface of the first plane 330 and the second plane 340, so that a certain cavity is still formed between the plastic support member 30, the door and window edge reinforcing plate 10, and the inner door panel 20, thereby absorbing energy during a collision. The first connecting surface 3310 and the second connecting surface 3410 can extend either in the direction of the vertical frame portion 320 or in the direction of the horizontal frame portion 310; preferably, the first connecting surface 3310 and the second connecting surface 3410 extend in the direction of the vertical frame portion 320.

[0038] There are multiple first connecting surfaces 3310 and second connecting surfaces 3410. The multiple first connecting surfaces 3310 are spaced apart on the first plane 330, and the multiple second connecting surfaces 3410 are spaced apart on the second plane 340. The multiple first connecting surfaces 3310 and second connecting surfaces 3410 are located at various positions on the surface of the plastic support member 30, making its connection with the door window edge reinforcing plate 10 and the door inner panel 20 more stable. Preferably, at least one first connecting surface 3310 and one second connecting surface 3410 are provided in the horizontal frame portion 310 and the vertical frame portion 320; the number of first connecting surfaces 3310 and second connecting surfaces 3410 can be two, three, etc., depending on the specific situation. In one embodiment, the number of first connecting surfaces 3310 is set to two, and the number of second connecting surfaces 3410 is set to three.

[0039] Multiple second connecting surfaces 3410 are projected onto the first plane 330 and are adjacent to the first connecting surface 3310. In other words, the second connecting surfaces 3410 are positioned corresponding to the positions between adjacent first connecting surfaces 3310 to enhance the strength between adjacent first connecting surfaces 3310, thereby increasing the strength of the plastic support member 30. That is, the first connecting surfaces 3310 and the second connecting surfaces 3410 are staggered. This ensures the rigidity of the plastic support member 30 while preventing it from becoming too thick, thus avoiding the plastic support member 30 being unable to be installed due to space constraints in the window frame's energy-absorbing cavity.

[0040] Multiple first reinforcing ribs 350 are provided between multiple adjacent first connecting surfaces 3310, and multiple second reinforcing ribs 360 are provided between multiple adjacent second connecting surfaces 3410. The multiple first reinforcing ribs 350 are connected to the multiple first connecting surfaces 3310, and the multiple second reinforcing ribs 360 are connected to the multiple second connecting surfaces 3410. The first reinforcing ribs 350 protrude from the first plane 330, and the second reinforcing ribs 360 protrude from the second plane 340. The first reinforcing ribs 350 and the second reinforcing ribs 360 help to improve the strength of the plastic support member 30. The multiple first reinforcing ribs 350 and the second reinforcing ribs 360 are distributed at intervals. The first reinforcing ribs 350 and the second reinforcing ribs 360 are connected to the first connecting surfaces 3310 and the second connecting surfaces 3410, so that when the plastic support member 30 is subjected to force through the first connecting surfaces 3310 and the second connecting surfaces 3410, the force can be transmitted through the first reinforcing ribs 350 and the second reinforcing ribs 360, making the force on the plastic support member 30 more uniform.

[0041] The vertical frame portion 320 is provided with a clearance hole 370. In some vehicle models, the vertical window frame portions of the door window edge reinforcement plate 10 and the inner door panel 20 are provided with wiring harness through holes. The clearance hole 370 is provided corresponding to the position of the wiring harness through holes. The wiring harness through holes and the clearance hole 370 are used to provide space for the installation of vehicle wiring harnesses. It should be noted that because the plastic support member 30 is made of plastic, even if the size of the vertical frame portion 320 is small, it is relatively easy to provide the clearance hole 370 on it. At the same time, the clearance hole 370 can also reduce the weight of the plastic support member 30.

[0042] The door and window frame structure 1 also includes a flange 380, which is bent and connected to the periphery of the horizontal frame 310 and the vertical frame 320. The flange 380 is configured to protrude from the first plane 330 or the second plane 340. On the one hand, the flange 380 allows the plastic support member 30 to bend and extend in different directions, which helps to improve the strength of the plastic support member 30; on the other hand, the flange 380 helps the plastic support member 30 form a cavity, which can collapse and absorb energy when the vehicle is impacted.

[0043] In summary, the door window frame structure 1 of this application strengthens the door window frame structure 1 by providing a plastic support member 30 within the window frame energy-absorbing cavity 40 between the door window edge reinforcing plate 10 and the door inner panel 20. The plastic support member 30 is made of plastic, making it easy to shape to fit the shapes of the door window edge reinforcing plate 10 and the door inner panel 20, and it is easy to install. The first connecting surface 3310 and the second connecting surface 3410 connect the door window edge reinforcing plate 10 and the door inner panel 20, increasing the strength of the plastic support member 30 and facilitating the formation of an energy-absorbing cavity with the door window edge reinforcing plate 10 and the door inner panel 20. The first reinforcing rib 350 and the second reinforcing rib 360 increase the strength of the plastic support member 30 while ensuring more even stress distribution.

[0044] This application also provides a door assembly, which includes a window glass and the aforementioned door window frame structure 1. The window glass is connected to the door window frame structure 1 and is connected within the opening formed by the window edge portion and the vertical window frame portion of the door window edge reinforcing plate 10 and the inner door panel 20.

[0045] This application also provides a vehicle that includes the aforementioned door assembly.
