Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. The inventor finds that the structural strength requirement of the joint of the top cover front cross beam and the side wall is high, and the weak areas can become collision bending induction areas which are easy to deform and fail due to the fact that welding through holes, large installation through holes and the like are formed in the connecting plate for installing the sun visor. Therefore, the application provides a connection structure of top cap front beam and side wall, it includes:
the roof front cross beam lower plate 1 is connected with the roof front cross beam connecting plate 2, the roof front cross beam lower plate 1 is provided with at least one third cavity 11, and the opening of the third cavity 11 corresponds to the position of the sun shield mounting hole 21 of the roof front cross beam connecting plate 2. The sun visor mounting hole 21 is a large solder via hole.
Specifically, as shown in fig. 3 and 4, the connection structure further includes: a side wall reinforcing plate 31 and a top cover front beam upper plate 4; wherein the content of the first and second substances,
a side gusset 31 provided between the side gusset outer panel 32 and the side gusset inner panel 33; the front end of the top cover front cross beam upper plate 4 is connected with the side wall reinforcing plate 31, the top cover front cross beam upper plate 4 is partially connected with the third cavity 11 of the top cover front cross beam lower plate 1 so that the top cover front cross beam upper plate 4, the side wall inner plate 33, the top cover front cross beam connecting plate 2 and the top cover front cross beam upper plate 4 are enclosed to form a first cavity 41, and the first cavity 41 corresponds to the position of the welding through hole 22 of the top cover front cross beam connecting plate 2. The tail end of the top cover front cross beam upper plate 4 is connected with the top cover front cross beam lower plate 1 to form a second cavity 42, and the second cavity 42 corresponds to the tail end of the top cover front cross beam connecting plate 2.
Preferably, the rear end of the roof front cross beam upper plate 4 is connected with the roof front cross beam lower plate 1 to form a second cavity 42, and the second cavity 42 corresponds to the end position of the roof front cross beam connecting plate 2. Optionally, the first cavity 41 corresponds to the front position of the roof front cross beam lower plate 1.
It should be noted that, as shown in fig. 1 and fig. 2, the first cavity 41 and the second cavity 42 are respectively disposed on two sides of the third cavity 11, and both the areas of the visor mounting hole 21 and the weld through hole 22 on the roof front cross member connecting plate 2 are collision bending induction areas in the stress analysis. And the first cavity 41 and the third cavity 11 act as reinforcing cavities for these two regions, respectively.
According to the invention, the reinforced cavities are arranged on the upper plate and the lower plate of the front cross beam of the top cover, and the cavities correspond to the welding through holes and the large installation through holes, so that collision bending induction areas caused by the characteristics of the welding through holes, the large installation through holes and the local installation of the third cavities of the sun shield are greatly reinforced, and the force transmission efficiency of side collision and top pressing is directly improved.
The inventor also finds that the first connection point C (i.e., the connection point between the roof front cross beam connection plate 2 and the front end of the roof front cross beam lower plate 1) and the second connection point D (i.e., the connection point between the tail end of the roof front cross beam connection plate 2 and the roof front cross beam lower plate 1) shown in fig. 1 are prone to collision, force transmission, bending, deformation and failure due to rapid material thickness and strength transition. In the present application, the first cavity 41 can be reinforced with respect to the solder via 22, and can also deal with the problem of the first connection point C caused by the rapid transition of the material thickness and the strength. Similarly, the second cavity 42 is also used to solve the failure of bending deformation at the second connection point D.
It should be noted that, as shown in fig. 1, the first connection point C is disposed at the front end of the roof front cross member lower plate 1, and the second connection point D corresponds to the end position of the roof front cross member connection plate 2. Wherein, the front end of the lower plate 1 of the front cross beam of the top cover refers to the connecting part of the left side of the third cavity 11 and the connecting plate 2 of the front cross beam of the top cover in figure 1. And the end of the roof front rail connecting plate 2 refers to a portion to the right of the third cavity 11 in fig. 1, which is connected to the roof front rail lower plate 1.
According to the invention, the welding position of the reinforced cavity and the welding position of the connecting plate with the difference in thickness are corresponding, so that the collision force transmission bending failure caused by the sharp transition of material thickness and strength at the welding position of the connecting plate of the front cross beam of the top cover and the inner plate of the front cross beam of the top cover is greatly improved, and the side collision and the top pressure bending edge shape are avoided.
After the side wall reinforcing plate 31 is passively extended, the material utilization rate is inevitably reduced, and the material consumption cost is increased; and side wall reinforcing plate 31 is long on the left, and its profile overlap joint department in actual production process, face profile tolerance is difficult to control, influences the effective laminating with the face of weld of top cap front beam inner panel, increases the part mould debugging degree of difficulty and matches the debugging cycle. Therefore, preferably, the length of the side wall reinforcing plate 31 in the Y direction is shortened to be aligned with the welding edges of the side wall outer plate 32 and the upper side beam inner plate, so that the arrangement difficulty of the side wall reinforcing plate blank can be improved, and the material utilization rate is greatly improved; after the length of the side wall reinforcing plate 31 in the Y direction is shortened, in order to ensure the connection between the side wall reinforcing plate and the top cover front beam upper plate 4, the length of the top cover front beam upper plate 4 is increased, but the blank length is changed because the top cover front beam upper plate 4 is of an approximately rectangular regular structure, and the material utilization rate is not affected.
According to the invention, the length of the side wall reinforcing plate is shortened, and the cost benefit is obviously improved; the problem that the profile tolerance of the middle-sized surface lap joint part is difficult to control in the actual production process is solved by directly solving the problem that the side wall reinforcing plate is long partially, and the debugging difficulty of the die and the matching and rectification period of parts are reduced.
It will be appreciated that the second cavity 42 and the first cavity 41 are each configured as a parallelogram to provide a desired draft angle for forming a steel plate to ensure material flow and forming.

Similarly, the second cavity 42 is also used to solve the bending deformation failure at the second connection point D.
