Specifically, as shown in fig. 1, the door window frame 100 is made of one plate material, the connection portion 30 is connected between the exterior portion 10 and the installation portion 20, and the exterior portion 10 and the installation portion 20 define a first installation space 1 on a first side (e.g., an upper side in fig. 1) of the connection portion 30 and define a second installation space 2 on a second side (e.g., a lower side in fig. 1) of the connection portion 30.

Therefore, the door and window frame 100 is made of one plate, that is, the door and window frame 100 in the utility model can be formed by bending one plate, so that the use amount of the plate is reduced, the weight of the door and window frame 100 is reduced, the light weight design of the door and window frame 100 is realized, and the welding position is reduced, so that the structural strength of the door and window frame 100 is ensured.

As shown in fig. 1, the exterior portion 10 is located at the vehicle exterior side, the installation portion 20 is directed toward the vehicle interior side, and the first installation space 1 and the second installation space 2 are located at the upper and lower sides of the connection portion 30, respectively, for connection with other structures of the vehicle body, thereby facilitating installation of the door and window frame 100 on the vehicle body to enhance structural stability of the door and window frame 100.

As shown in fig. 1, the connection portion 30 includes a first layer of sub-board 31 and a second layer of sub-board 32 that are bonded together.

One end (left end in fig. 1) of the first-layer sub-board 31 facing away from the mounting portion 20 is formed as a first free end 311 of the board, one side of the appearance portion 10 facing the connecting portion 30 is provided with a convex extension flange 11, an end (right end in fig. 1) of the extension flange 11 is formed as a second free end 111 of the board, and a welding area 3 is formed at a joint of the first free end 311, the second free end 111 and the second-layer sub-board 32.

It should be noted that, the first free end 311 and the second free end 111 are two ends of the above-mentioned plate respectively, so that the welding is performed at the connection between the first free end 311, the second free end 111 and the second layer of sub-board 32 to form the welding area 3, that is, the connection between the two ends of the plate and the second layer of sub-board 32 is welded, so that the welding difficulty can be reduced, and the sagging phenomenon of coating can be avoided.

It should be noted that, the actual position of the welding area 3 of the door window frame 100 of the present utility model can be adjusted according to the positions of the first free end 311 and the second free end 111, so that the actual position of the welding area 3 can be flexibly changed according to the production requirement, and the adjustment of the actual position of the welding area 3 is further facilitated.

For example, the door and window frame 100 is formed by bending a plate, the appearance portion 10 and the mounting portion 20 are of a cavity structure formed by bending the plate, the appearance portion 10 and the mounting portion 20 are connected through the connecting portion 30, the door frame bright wisp 6 can be mounted on the appearance portion 10, and the door opening sealing strip 7 is mounted on the mounting portion 20.

The connection portion 30 includes a first layer of sub-board 31 and a second layer of sub-board 32, a first free end 311 of the first layer of sub-board 31 is formed at one end facing the vehicle outside, an extension flange 11 is disposed at one side of the connection portion 30 facing the connection portion 30, the extension flange 11 extends along a length direction (a direction from the vehicle outside to the vehicle inside in fig. 1) of the connection portion 30, and an end (a right end in fig. 1) of the extension flange 11 forms a second free end 111.

In actual welding, the first free end 311, the second free end 111 and the connection portion 30 of the second layer of sub-board 32 are welded to form the welding area 3, so that welding can be performed at the connection portion between the two ends of the board and the second layer of sub-board 32, welding difficulty is reduced, and coating sagging phenomenon can be avoided.

According to the door window frame 100 of the embodiment of the utility model, the welding is performed at the connection position of the first free end 311, the second free end 111 and the second layer of sub-board 32 to form the welding area 3, namely, the connection position of the two ends of the plate and the second layer of sub-board 32 is welded, so that the welding difficulty can be reduced, the phenomenon of coating sagging can be avoided, and meanwhile, the use amount of the plate can be reduced, the weight of the door window frame 100 is reduced, and the lightweight design of the door window frame 100 is facilitated.

In some embodiments, as shown in fig. 2, the first free end 311 is welded to the second free end 111 and the second layer sub-board 32, respectively.

Therefore, the first free end 311, the second free end 111 and the second layer sub-board 32 can be welded and connected sequentially, namely welded layer by layer, so that the welding firmness can be ensured.

Further, the second free end 111 is attached to a side of the first free end 311 facing away from the second layer sub-board 32.

In other words, the second free end 111 is overlapped on the side of the first free end 311 facing away from the second sub-board 32, so that the first free end 311 and the second sub-board 32 can be welded at first during actual welding, at this time, the welding position of the first free end 311 and the second sub-board 32 is close to the position of the first free end 311, and then the second free end 111 is welded on the side of the first free end 311 facing away from the second sub-board 32 to form the welding area 3, so as to facilitate welding. The second free end 111 can cover the welding position (the welding position between the first free end 311 and the second layer of sub-board 32) below to hide the welding position, and meanwhile, the extending flange 11 and the first free end 311 can define a cavity on the upper side of the second layer of sub-board 32, and the cavity can be used for containing welding slag, so that the welding area 3 is cleaner, and coating sagging phenomenon is avoided.

It should be noted that, the welding area 3 of the leaking portion is a welding position between the second free end 111 and the first free end 311, and the second free end 111 is overlapped on one side of the first free end 311 facing away from the second layer sub-board 32, so that the area of the welding area 3 of the leaking portion is actually adjusted by overlapping the second free end 111 with the area of the portion of the first free end 311, and the area of the overlapping portion of the second free end 111 with the portion of the first free end 311 is smaller, which is beneficial to reducing the area of the welding area 3 and reducing the welding difficulty.

In other embodiments, as shown in fig. 3, the second layer daughter board 32 is welded to the first free end 311 and the second free end 111, respectively.
