Referring to fig. 1, in the present embodiment, a sealant 4 may be disposed between the lower portion of the guide groove 21 and the rear wall outer panel 1; the rear windshield reinforcing structure can also comprise a left longitudinal beam 5 positioned on the left side of the rear windshield 7 and a right longitudinal beam 6 positioned on the right side of the rear windshield 7; one end of the guide groove 21 is connected with the left longitudinal beam 5, and the other end of the guide groove is connected with the right longitudinal beam 6, so that condensed water in the guide groove 21 is connected to a bottom plate beam cavity hole of the vehicle through the left longitudinal beam 5 and the right longitudinal beam 6 and flows out of a cab; the reinforcing panel 2 may further comprise a left flange 25 located on the left side of the rear louver 7, the left flange 25 connecting the left longitudinal beam 5, and a right flange 26 located on the right side of the rear louver 7, the right flange 26 connecting the right longitudinal beam 6.

The principle of the rear windshield reinforcing structure and the vehicle provided by the embodiment of the invention is as follows:

because the reinforcing plate 2 is arranged around the rear windshield 7 of the vehicle, the reinforcing plate 2 is provided with the guide groove 21 which can contain the condensed water on the outer plate 1 of the rear wall, the guide groove 21 is positioned above the rear windshield 7, when condensed water exists on the rear wall outer plate 1, the condensed water can flow down to the guide groove 21 of the reinforcing plate 2 along the inner wall of the rear wall outer plate 1, the subsequent condensed water can flow along the flow path provided in the guide groove 21, and after the condensed water flows to the end of the guide groove 21, condensed water can be led to two opposite sides of the rear windshield 7 through two ends of the guide groove 21, so that the condensed water is prevented from directly flowing downwards onto the glass of the rear windshield 7 along the rear wall outer plate 1, meanwhile, the accumulation of condensed water at the seam allowance at the upper part of the rear windshield 7 can be prevented, which causes the seam allowance at the upper part of the rear windshield 7 to rust, therefore, a large amount of felt does not need to be pasted on the upper part of the rear windshield 7, and the method is low in cost and easy to realize.

In the description of the present invention, it should be noted that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention. Unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are intended to be inclusive and mean, for example, that they may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

It is to be noted that, in the present invention, relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The foregoing are merely exemplary embodiments of the present invention, which enable those skilled in the art to understand or practice the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
