[0023] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0024] In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0025] like Figures 1 to 6As shown, a framed door frame of the utility model includes a frame body 10, and the frame body 10 includes an upper beam 101, a lower beam 102, a front pillar 103 and a rear pillar 104 that are integrally die-cast. The upper beam 101, the lower beam 102, the front pillar 103 and the rear pillar 104 form a U-shaped structure; it forms a cavity structure, provides equipment installation space, and reduces weight. A window frame 11 is arranged above the frame body 10, and the window frame 11 is connected to the upper beam 101 and extends upward. The top of the window frame 11 is arranged in an arc shape and is adapted to the shape of the window. The window frame 11 is provided with a gap for accommodating the window, and a (sealing strip) for sealing the window is arranged thereon. The frame body 10 and the window frame 11 are integrally die-cast. An outer panel mounting frame 12 is arranged on the outside of the skeleton body 10, and the outer panel mounting frame 12 includes a base 121 fixedly arranged at the intersection of the upper beam 101 and the rear column 104, and an extension portion 122 connected to the base 121 and extending toward the lower beam 102 and the front column 103, and the extension portion 122 is an arc-shaped structure protruding outward.

[0026] The base 121 and the extension 122 are integrally die-cast. The extension 122 may not be connected to the skeleton body 10, or may be connected to the skeleton body 10 by welding or riveting. In this case, the connection strength between the base 121 and the skeleton body 10 is greater than the connection strength between the extension 122 and the skeleton body 10, so that the extension 122 can be loosened when subjected to force. The extension 122 is provided with a plurality of bending portions 123 to provide ductility when subjected to force; a plurality of reinforcing plates 124 are vertically provided on the inner side of the extension 122 to increase strength;

[0027] An inner reinforcement beam 14 is disposed outside the frame body 10. Two ends of the inner reinforcement beam 14 are fixedly disposed at the upper beam 101 and the rear pillar 104, respectively.

[0028] When the utility model is subjected to an external impact force perpendicular to the door, the outer panel mounting frame 12 is stressed, and its base 121 ensures the connection strength, and the extension 122 is free or loose under stress, and the arc-shaped extension 122 can extend along the frame body 10, converting the impact force into a force along the lateral direction of the door, forming a collapse energy absorption, thereby playing the role of replacing the anti-collision beam. When the collapse energy effect is maximized, the inner reinforcement beam 14 supports the frame body 10 to achieve a rebound effect.

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
