The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of this patent.

In order to better understand the improvements made by the present invention over the prior art, before describing the specific implementation of the present invention in detail, the structure of the articulated truck cab is first introduced. As shown in FIG1 , the top of the articulated truck cab is a cab roof, and below the cab roof is a cab sheet metal 2, which is located above the cab front windshield. The front windshield lower view mirror assembly for the articulated truck disclosed in the present invention is installed on the cab sheet metal 2.

As shown in FIG1 , the front windshield lower view mirror assembly for an articulated truck includes an external mounting bracket 1, which is mounted on the outside of the cab and extends toward the front of the cab. The rear end of the external mounting bracket 1 is fixed to the cab sheet metal 2 on the top of the cab. In one example, a lower view mirror body 4 is mounted on the front end of the external mounting bracket 1. As shown in FIG2 , the front end of the external mounting bracket 1 cooperates with a nut and a locking bolt 3 to fix the lower view mirror body 4. The mirror surface of the lower view mirror body 4 is convex, and the convex surface faces downward.

The downward-view mirror body 4 is installed in front of the cab sheet metal 2 through the external mounting bracket 1, and the mirror surface faces downward. Therefore, the driver in the cab can observe the situation in front and below the vehicle through the downward-view mirror body 4. Moreover, the mirror surface of the downward-view mirror body 4 is convex, which is conducive to expanding the observation range, allowing the driver to observe the road conditions more clearly, and helping to improve driving safety.

As shown in FIG. 2 , the down-view mirror body 4 further includes a mounting seat 5, which is located on the back of the mirror surface. In order to facilitate the installation of the down-view mirror body 4, the mounting seat 5 is provided with through holes running through the left and right sides thereof. In addition, a through hole is also provided at the front end of the corresponding outer mounting bracket 1. During installation, the locking bolt 3 is passed through the through holes at the front end of the mounting seat 5 and the outer mounting bracket 1 respectively, and finally the nut is tightened onto the locking bolt 3, so that the fixing between the mounting seat 5 and the outer mounting bracket 1 can be ensured.

Preferably, the mounting seat 5 is located in the middle of the back of the lower-view mirror body 4 in the front-to-back direction, which can improve the stability of the lower-view mirror body 4. At the same time, a washer Ⅰ6 is also provided at the portion where the outer mounting bracket 1 is connected to the lower-view mirror body 4, and the washer Ⅰ6 can be penetrated by the locking bolt 3. Through the tightening action of the bolt, the washer is tightly compacted, which can further enhance the stability of the connection between the outer mounting bracket 1 and the lower-view mirror body 4 and reduce the shaking of the lower-view mirror body 4 during the vehicle's travel.

As shown in FIG. 1 and FIG. 4 , a base 7 is also provided at the rear end of the external mounting bracket 1. The base 7 is a plate-like structure used to enhance the stability of the bracket. Bolt holes for fixing bolts 8 to pass through are provided at the four corners of the base 7. In this way, when installing the external mounting bracket 1, the base 7 can be connected to the cab sheet metal 2 using the fixing bolts 8, and then tightened with nuts, thereby achieving a secure fixation between the external mounting bracket 1 and the cab sheet metal 2, thereby improving the stability of the external mounting bracket 1.

Preferably, as shown in FIG3 , an inner mounting bracket 9 is also provided on the inner side of the cab sheet metal 2 at the corresponding position of the outer mounting bracket 1. As shown in FIG4 , the inner mounting bracket 9 is close to the cab sheet metal 2, and the fixing bolt 8 needs to pass through the base 7, the cab sheet metal 2 and the inner mounting bracket 9 in sequence, and then be tightened and fixed with the nut. Such a design can further improve the stability of the outer mounting bracket 1. It should be understood that the inner mounting bracket 9 and the outer mounting bracket 1 are both made by bending technology, without the need for mold opening, and are easy to make.

In addition, a washer II 10 is provided between the fixing bolt 8 and the outer mounting bracket 1. The washer II 10 can be a spring washer. When the washer II 10 is pressed by the fixing bolt 8, the stability of the outer mounting bracket 1 can be further improved, and the dizziness of the driver when looking at the lower mirror body 4 caused by the shaking of the lower mirror body 4 under bumpy road conditions can be reduced.
