Detailed Description
For ease of illustration and understanding, several basic directional and positional concepts are first described and defined. The inner side is the side close to the carriage, and the outer side is the side far away from the carriage.
As shown in fig. 1 to 4, an installation structure of an electric stay bar of a back door comprises a back door inner plate 10, wherein one end of the electric stay bar 20 is fixedly installed on the inner side plate surface of the back door inner plate 10 through an installation plate 30, a reinforcing plate 40 is welded on the outer side plate surface of the back door inner plate 10, and the installation surface of the installation plate 30 and the back door inner plate 10 and the welding surface of the reinforcing plate 40 and the back door inner plate 10 are respectively two side plate surfaces of a plate body near the same region of the back door inner plate 10. The reinforcing plate 40 is arranged on the other side of the mounting surface of the mounting plate 30 and the back door inner plate 10, namely the reinforcing plate 40, the mounting plate 30 and the back door inner plate 10 are welded into a whole, so that the problems of local rigidity and strength of the mounting point of the electric stay bar 20 are solved, the structure of the back door inner plate 10 is reinforced, the integral mode of the back door is improved, and the problems of abnormal sound, shaking, deformation and the like of the back door are prevented.
Preferably, the reinforcing plate 40 includes a reinforcing plate 41, the welding surface of the upper reinforcing plate 41 and the mounting plate 30 is just opposite to the setting, and the welding area of the upper reinforcing plate 41 and the back door inner plate 10 is greater than the mounting area of the mounting plate 30 and the back door inner plate 10, the upper reinforcing plate 41 is a multi-stage bending plate attached to the back door inner plate 10, a first flanging 411 turned over in the direction away from the back door inner plate 10 is arranged on the periphery of the bending plate, and a welding spot is arranged at the attaching position of the first flanging 411 and the back door inner plate 10. Design the orderly binding face of level on multistage bent's the last reinforcing plate 41, be connected to together these binding faces and back door inner panel 10 through the solder joint, the solder joint is through optimizing, and is rationally distributed, and the transmission route of increase power is favorable to dispersing local stress, improves the local strength of mounting point, prevents panel beating and solder joint fracture.
Two mounting holes 412 are formed in the corresponding plate surfaces of the upper reinforcing plate 41 and the mounting plate 30, and first positioning holes 413 are formed in the plate surfaces of the upper end and the lower end of the upper reinforcing plate 41, so that position deviation in the assembling process is prevented; the first lightening holes 417 are formed in the plate body between the two first positioning holes 413 to achieve the purpose of lightening, so that the plate body can meet the requirements on rigidity and strength on the premise of the lightest weight, and the first flanges 411 on the left side and the right side of the upper reinforcing plate 41 are provided with buckle avoiding holes 414. These holes are formed in the upper reinforcing plate 41 at positions that have little influence on rigidity and strength.
In order to improve the local rigidity of the mounting point, the plate surface of the area where the mounting hole 412 is located is provided with reinforcing ribs 415 which are arranged transversely and vertically, and meanwhile, the reinforcing ribs 415 can further enhance the overall rigidity of the upper reinforcing plate 41 and prevent the deformation of a metal plate; because the space is limited, the cavity between the upper reinforcing plate 41 and the back door inner plate 10 is small, and the electrophoretic liquid is not easy to discharge during coating, a plurality of liquid leakage holes 416 are formed in the reinforcing ribs 415, so that the coating electrophoretic liquid can be effectively discharged.
Further, the mounting hole 412 is welded with the upper reinforcing plate 41 through a projection nut welding process, so that the welding strength and the assembling stability are improved, and the problem of deformation and cracking caused by uneven force transmission at the mounting hole 412 is solved.
The lower end of the upper reinforcing plate 41 extends downwards to form a lower reinforcing plate 42, the lower reinforcing plate 42 is also a multi-stage bending plate attached to the back door inner plate 10, a second flanging 421 is arranged on the periphery of the bending plate, and a welding spot is arranged at the attaching position of the second flanging 421 and the back door inner plate 10. Due to the arrangement of the lower reinforcing plate 42, the upper span and the lower span of the reinforcing plate 40 are large, the relatively weak position of the upper inflection point and the lower inflection point of the back door inner plate 10 is enhanced, the overall mode and the rigidity of the back door inner plate 10 are facilitated, and the problems of abnormal sound, shaking, deformation and the like of the back door inner plate 10 are prevented.
Similarly, for convenience of installation, two second positioning holes 422 are formed in the plate body of the lower reinforcing plate 42, and for weight reduction, a second lightening hole 423 is formed in the plate body between the two second positioning holes 422.
