Example 1.
The invention provides a back door metal plate for assembling an electric empennage, which comprises a tail door outer plate I, a tail door outer plate II, a supporting plate and a tail door inner plate, and is shown in figure 3.
The front end of the outer tail door plate I is provided with two sheet metal bridges, the middle of each sheet metal bridge is sunken inwards, two ends of each sheet metal bridge are connected with the outer tail door plate I, and the hollow parts at the front end of the outer tail door plate I are divided into three outer plate openings by the sheet metal bridges.
In the embodiment, two sides of the hollow part at the front end of the tail door outer plate I are respectively provided with 4 tail wing bolt mounting holes; the flange parts at the two sides of the supporting plate are provided with nut mounting surfaces; the tail door is characterized in that through holes allowing tail wing bolts to pass through are formed in the nut mounting surfaces, 4 through holes are formed in the nut mounting surfaces on the two sides respectively, and two rows of 4 tool through holes are formed in the front end of the inner plate of the tail door. When the tail wing bolt mounting hole, the through hole and the tool through hole which are arranged on the nut mounting surface are welded into an assembly by a metal plate, the positions of the through holes and the tool through hole sequentially penetrate through and correspond to each other.
In the embodiment, the support plate is made of a hot-rolled steel plate with the yield strength of 300MPa, and other high-strength steel materials can be selected, so that the rigidity and the strength of the empennage connection point are guaranteed.
During welding, the component assemblies are welded at the flanging positions of the two sides of the supporting plate at the outer plate I and the supporting plate, the component assemblies and the outer plate II are welded into the outer plate assembly in a combined mode and then are subjected to edge covering welding with the inner plate, in order to achieve sheet metal integration and improve overall sheet metal rigidity, the supporting plate and the inner plate are welded at the joint of the two, a welding schematic diagram is shown in figure 4, and due to the fact that an outer plate opening is formed in the upper surface of the outer plate I, accessibility of a welding tongs is achieved. After welding, the bottom of the metal plate bridge is in contact with the surface of the supporting plate.
As shown in fig. 5, the welded assembly of the sheet metal system is shown, the outer plate of the tail door has 3 outer plate openings for avoiding the internal mechanism of the tail wing, and the outer plate opening 1 and the outer plate opening 2 are used for the hinge mechanism of the tail wing to pass through and extend into the sheet metal; the outer plate is provided with an opening 3 for the empennage motor to pass through and enter the metal plate system. The sheet metal bridge structure in the middle of the outer plate opening is used for avoiding the problem that the sheet metal strength is insufficient due to the fact that large holes are formed in the sheet metal, and the sunken structure in the middle of the sheet metal bridge is used for avoiding a transmission shaft between the empennage motor and the hinge.
Example 2.
A method for installing an electric empennage on a sheet metal of a back door as described in embodiment 1. The mounting process of the electric empennage is shown in the figures 6 and 7, the electric empennage assembly (only a base is shown in the figures) falls into the outer plate hole downwards along the Z direction, fixing bolts are arranged on the periphery of the electric empennage along the base, the bolts are butted into empennage bolt mounting holes and through holes formed in a nut mounting surface, a screwing tool penetrates through tool through holes reserved in the inner plate, the nuts are screwed with bolts of the empennage assembly, and the electric empennage is fixed.
As shown in figure 7, the nut fixing surface is located on a support plate of the sheet metal system, the support plate is a hot rolled steel plate with the yield strength of 300MPa, rigidity and strength of a tail wing connecting point are guaranteed, and meanwhile, after the tail wing is lifted, under the action of large wind resistance and pressure, stress of an outer plate of the tail door is transmitted to an inner plate through the support plate so as to reach the whole sheet metal system, pressure is effectively dispersed, and the overall reliability of a sheet metal is improved.
As shown in figure 6, after the empennage is installed, the motor and the hinge fall into the outer plate opening, the transmission shaft falls into a set sheet metal bridge, and the problems that in the prior art, the gap between the inner plate and the outer plate of the tail door is close due to the fact that the outer plate of the tail door is integrally concave down and avoids the inner structure of the empennage, and then the integral rigidity of the sheet metal is poor, and a bending induction structure and a mode are weak are effectively solved.
The back door panel beating passes through the sealed of the dry chamber of panel beating of electronic fin base rather than fitting surface whole circle sealing strip structure realization panel beating, prevents effectively that the rainwater from getting into the inside motor scheduling problem that ablates of panel beating.
Example 3.
The invention also provides an automobile which is provided with the back door metal plate structure in the embodiment 1.
