Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door structure design, in particular to a vehicle door outer panel window frame reinforcement structure. Background Art

[0002] The strength of the door is generally improved by welding the outer panel window frame reinforcement plate, the inner panel reinforcement plate and other parts between the inner and outer panels of the door. With the development of vehicle intelligence, the hidden door handle technology is more and more widely used, but the use of hidden door handles puts higher requirements on the strength of the door. Since the window frame layout space at the waistline of the door is narrow, it is not conducive to the layout of too many reinforcements. Therefore, in the related art, the hidden door handle installation is completed by integrating the door handle installation position on the outer panel window frame reinforcement plate. However, the integration of the door handle installation position on the outer panel window frame reinforcement plate requires the opening of the door handle installation through hole, which has a certain impact on the strength and rigidity of the outer panel of the door, and is prone to cause problems such as jamming and abnormal noise in the glass lifting system. In the prior art, the strength and rigidity of the window frame of the outer panel of the door are generally ensured to be unaffected by increasing the thickness of the outer panel window frame reinforcement plate or replacing it with a high-performance material, but this makes the production cost higher. Therefore, it is necessary to improve the design of the reinforcement structure of the existing door outer panel window frame, so as to facilitate the layout and installation of hidden door handles, and at the same time, to ensure the structural strength and rigidity requirements of the door outer panel at a lower cost and reduce quality and safety hazards. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a door outer panel window frame reinforcement structure, which can facilitate the arrangement and installation of hidden door handles, and at the same time can help ensure the structural strength and rigidity requirements of the door outer panel at a lower cost, thereby reducing quality and safety risks.
