Abstract
The utility model discloses a be suitable for side wall overlap joint structure of new forms of energy motorcycle type is provided with sheet metal construction between B post inner panel and roof beam, and sheet metal construction's one end and B post inner panel are rigid to be connected, and the other end is rigid with the roof beam to be connected, the place in order to form side wall overlap joint structure. The utility model discloses under the condition of opening the mould less, reduce welding processes to satisfy the B post inner panel that side impact probably appears and throw off the problem, make the B post become a whole, reach side impact invasion amount and whole biography power requirement.
Description
Technical Field
The utility model relates to an automobile body accessory technical field specifically is a be suitable for side wall overlap joint structure of new forms of energy motorcycle type.
Background
As a safety regulation which is the same as the Chinese new car evaluation program (C-NCAP), the Chinese insurance automobile safety index (C-IASI) gradually improves the whole car safety performance threshold, and arouses the attention of each large host factory. The side collision is high (379 mm) from the ground, heavy (1500 kg) and high in deformed honeycomb aluminum hardness, so that higher requirements are provided for the collision resistance of the side collision of the whole vehicle.
The side collision is that the impact force is born by the B pillar, the front side door and the rear side door, and meanwhile, the impact force is transmitted to the opposite side of the collision through the doorsill and the side wall side beam, so that a good force transmission path is the heavy of the side collision. In this case, the overlapping position is particularly important.
At present, the mode adopted by each large host factory is to increase the lapping surfaces of a B-pillar reinforcing plate, an inner plate, a threshold and an upper boundary beam, and the lapping problem can be well solved by the mode. As long as the welding process is guaranteed, there is no problem with the consistency. However, this case has the following problems: (1) the material utilization rate is low, and the waste rate is increased; (2) the process is multiple, and the lapping position of the reinforcing plate and the inner plate is subjected to hole forming treatment for light weight; (3) the existing platform needs to be redesigned, and the fixed investment cost is increased.
In recent years, due to the fact that the vehicle model is accelerated, the scheme of few mold opening, short period and almost no increase of the process is gradually accepted by a host factory, the improvement of the side collision crashworthiness is realized by adopting a simplified design besides a B column lifting material, and the side wall lap joint also meets the requirement of the collision performance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a be suitable for new forms of energy motorcycle type's side wall overlap joint structure to solve the problem that proposes in the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a be suitable for side wall overlap joint structure of new forms of energy motorcycle type, is provided with the sheet metal construction between B post inner panel and roof beam, the one end and the rigid connection of B post inner panel of sheet metal construction, the other end and the rigid connection of roof beam, the place in order to form side wall overlap joint structure.
Preferably, the sheet metal structure is fixedly connected with the top cross beam.
Preferably, the sheet metal structure is a T-shaped structure.
Preferably, the thickness of the sheet metal structure is between 1.5mm and 1.8 mm.
Preferably, the sheet metal structure adopts a spot welding mode and is fixedly connected with the upper side beam.
Preferably, the sheet metal structure is fixedly connected with the B column inner plate/top beam through bolts.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses under the condition of opening the mould less, reduce welding processes to satisfy the B post inner panel that side impact probably appears and throw off the problem, make the B post become a whole, reach side impact invasion amount and whole biography power requirement.
And, be applicable to current platform short period motorcycle type. The original structure adjustment is not involved, so that the large-amplitude adjustment is not needed; the solid investment cost is reduced. Because newly developed parts are few, the fixed investment is small, the calibration is flexible, and the period can be ensured; the reasonable structure can improve the utilization rate of materials and reduce the purchase cost; the vehicle type with higher requirement on the side collision resistance can be quickly coped with, and the safety performance is improved; the method has a very obvious reinforcing effect on B-pillar hot forming spot welding parts in particular.

Detailed Description
In order to facilitate the use, the embodiment of the utility model provides a be suitable for new forms of energy motorcycle type's side wall overlap joint structure. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
This embodiment provides a be suitable for side wall overlap joint structure of new forms of energy motorcycle type, shows in referring to, is provided with sheet metal structure 1 between B post inner panel 4 and roof side rail 2, and sheet metal structure 1's one end and B post inner panel 4 rigid connection, the other end and roof side rail 2 rigid connection, the way in order to form side wall overlap joint structure. The B-pillar inner plate 4 is similar to the middle layer of the three layers of sandwiches, and the sheet metal structure 1 firmly fixes the B-pillar inner plate 4 through spot welding, bolt connection and the like. In the event of an impact in a side collision, the entire side surface assumes an integral, firm structure even if the B-pillar inner panel 4 does not come off. The B column has no obvious stress concentration position and no fracture and other conditions.
One end of the metal plate structure 1 is fixedly connected with the top cross beam; as shown in the figure, the sheet metal structure is T-shaped, the material can be selected from HC340/590DP, and the thickness is between 1.5mm and 1.8 mm. The sheet metal structure 1 is fixedly connected with the upper side beam 2 in a spot welding mode, and the sheet metal structure 1 is fixedly connected with the B column inner plate 4/top beam 3 through bolts. As shown, at 6 in the figure, is a bolt connection position, and at 5 in the figure, is an electric welding position.
After the B column and upper side beam lap joint structure is adopted, the C-IASI does not have the condition that the B column inner plate is separated, the B column stress is concentrated, and the fracture risk is caused. The B-pillar invasion amount meets the target requirement, and the side door invasion amount also meets the target requirement.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
