Detailed Description

The following explains an embodiment of the present invention with reference to the drawings.

As shown in fig. 1 and 2, the present embodiment is applicable to an exterior trim panel structure of an external airtight door, including: an upper mounting bracket 8 and a lower mounting bracket 9 fixed to the vehicle body 1, and an outer panel 10 hinged to the upper mounting bracket 8. As shown in fig. 1, the vehicle body 1 is provided with an upper T-shaped vehicle body groove 2 and a lower T-shaped vehicle body groove 2, one end of an upper mounting bracket 8 is hinged with an outer decorative plate 10 through a hinge 4, and the other end is hung on the T-shaped vehicle body groove 2. Slidable T-shaped bolts are placed in the two vehicle body T-shaped grooves 2, and the T-shaped bolts penetrate through the upper mounting support 8 and the lower mounting support 9 respectively and are fastened through nuts. Downward load is borne by a T-shaped groove of the vehicle body, and the T-shaped bolt is only subjected to axial force, so that the mounting support is prevented from moving downwards after long-time vibration.

The inside wall of plaque 10 lower part is provided with the plaque T type groove 3 that the opening is inside, is provided with slidable bolt in plaque T type groove 3, and the bolt passes down installing support 9 after to fix through the nut. Lower installing support 9 is the U type, realizes sheltering from inside.

Lower installing support 9 both ends respectively with on automobile body T type groove and the plaque T type groove 3 fastening connection, can avoid the fastener directly to expose in the rainwater, avoid the work of on-the-spot drilling of joining in marriage simultaneously, improve production efficiency.

The automobile body 1 has overhanging automobile body eaves 11, the outside embedding of outer plaque 10 upper end has sealing strip 6 (waterproof bubble is cotton), and when outer plaque 10 closed condition, sealing strip 6 supports the inside wall of tight automobile body eaves 11 to it is waterproof to realize. By the lower fastening piece cooperating with the hinge 4, the tighter the lower fastening, the better the tightness of the upper part. Multiple waterproof structural designs are provided. The back of the upper mounting bracket 8 is provided with a clamp spring 5, the inner side of the upper end of the outer decoration plate 10 is provided with a ball head 7, and when the outer decoration plate 10 is in an open state, the ball head 7 is clamped into the clamp spring 5 to fix the outer decoration plate 10 in the open state.

When the internal equipment of the external decoration plate 10 needs to be maintained, the external decoration plate 10 is opened to the maximum state, and the ball head 7 of the external decoration plate 10 is fixedly clamped by the clamp spring 5, so that the external decoration plate 10 is fixed in the maximum opening state, and the maintenance operation can be carried out without completely dismounting the external decoration plate.

The core of this patent is through hinge 4 realization easy maintenance performance, through purpose-made last installing support 8 with decurrent load transfer to the automobile body on, realize waterproof performance through three-dimensional waterproof bubble cotton (sealing strip 6) cooperation hinge "seesaw" principle and automobile body eaves.

The mounting of the upper mounting bracket 8 shown in this patent is only one of a variety of mounting arrangements. If the vehicle body outer side has no T-shaped groove, the vehicle body outer side can be fastened by a structure such as pre-assembling a rivet nut or a built-in threaded slider on the vehicle body. These fastening means are all within the scope of this patent.

This patent is applicable to externally mounted equipment and equipment have waterproof and the vehicle structure who maintains the requirement simultaneously, like outer hanging door vehicle structure.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
