Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body architecture, and in particular to a universal front panel assembly and a cabin assembly based on an electric architecture platform. Background Art

[0002] The dash assembly is one of the important components of the car body and is also an independent assembly on the front end module of the car body. Its main function is to provide support points and installation points for the car's front windshield structure, wiper structure, air conditioning structure, engine hood hinge, instrument panel structure and other components to play their functions. The dash assembly of the car body is a structural assembly that separates the front part of the car body from the cockpit. The dash assembly is generally welded by the dash upper plate, dash upper lower plate and reinforcement plate and other components. It usually adopts a box-shaped cross-section structure with great torsional rigidity. The dash upper plate is welded to the front pillars of the left and right side panels of the car body through the end plates on both sides. It is the main structural component that determines the torsional rigidity of the car body.

[0003] In the process of body development, traditional models generally only consider one model, and the commonality rate of parts is not high. The biggest difference between electric vehicles and traditional fuel vehicles in structure lies in the power system. Therefore, for the structure of the front panel assembly and the cabin assembly of the body, when developing new models, based on the electric architecture platform, the front panel assembly can be common to high and low cars (from coupes to sports utility vehicles SUVs). The high and low cars refer to the height dimensions of the models. Models with higher dimensions, such as SUVs, are referred to as high cars, and models with lower dimensions, such as coupes, are referred to as low cars. In this way, by designing a common front panel assembly and cabin assembly, the commonality rate of parts can be increased and the cost of the whole vehicle can be reduced. Summary of the invention

[0028] See also Figures 1 to 3 The present invention provides a universal dash panel assembly based on an electric architecture platform, comprising a dash panel body 1, a dash cross beam assembly 2, a dash panel connecting plate 3 and an assembly mounting surface 4; wherein the dash cross beam assembly 2 is connected to the back of the dash panel body 1, and the two ends of the dash cross beam assembly 2 are connected to the vehicle body structure; the dash panel connecting plate 3 comprises a dash panel left connecting plate 31 and a dash panel right connecting plate 32 connected to the two ends of the bottom of the dash panel body 1, and the dash panel body 1 is connected to the vehicle body structure through the dash panel left connecting plate 31 and the dash panel right connecting plate 32; the assembly mounting surface 4 is arranged on the dash panel body 1, and the position of the assembly mounting surface 4 on the dash panel body 1 is determined according to the vehicle model of the electric architecture platform; the upper boundary of the dash panel assembly A is determined according to the overlapping surface of the dash panel body 1 and the water trough assembly B of the vehicle model, and the lower boundary of the dash panel assembly A is determined according to the overlapping surface of the dash panel body 1 and the dash lower main board assembly F of the vehicle model.

[0029] In this embodiment, the development of new models based on the electric architecture platform has a higher parts commonality rate, thus having a cost advantage. In the development process of specific models of the electric architecture platform, the dash assembly A is both a part of the cabin assembly structure, connected and fixed to the body structure through the cabin assembly, and the dash assembly A also includes a part that is directly connected and fixed to the body structure. Based on this, the universalization strategy of the dash assembly A structure needs to be determined based on its own upper and lower boundaries.

[0030] It should be noted that in the process of developing the universal parts of vehicle models, the purpose of maintaining the upper and lower boundaries of the dash assembly A structure (i.e., determining the minimum height dimension of the dash assembly A structure, and then developing universalization based on different vehicle models on the basis of this minimum dimension to assemble the cabin assembly) is to ensure the common use of high and low vehicles (the main difference between high and low vehicles in the cabin position is the different seat R points <At the beginning of the overall layout design of the car, a hip point when the seat is adjusted to the last and lowest position is determined according to the overall layout requirements, and this point is called R point>. The low car is mainly a coupe, and the high car is SUV, but not limited to this, and can also be used for models between coupes and SUVs). The upper boundary of the dash assembly A is determined by the low car, according to the position of the low car's front windshield, and the wiper option. The windshield of the low car (related to the shape) determines the upper boundary of the cabin dash assembly A, and then the upper boundary of the dash assembly A is derived according to the envelope size of the wiper option. The lower boundary of the dash assembly A is mainly determined by the layout of the steering column of the low car, and can be made under the premise of ensuring the sealing structure of the dust cover. For the height dimension of the dash assembly A structure of the high car, the height dimension of the water trough assembly B overlapped with the dash assembly A and the height dimension of the dash lower main assembly F can be designed to make up for the lack of height dimension of the dash assembly A structure determined based on the low car, so as to realize the universal development of the dash assembly A structure on different models in the same electric architecture platform. That is, in the above way, the boundary and dimension of the dash assembly A in the electric architecture platform are determined according to the boundary of the dash assembly A of the low car.

[0031] By maintaining the upper boundary (the overlapping surface between the front panel body 1 and the water gutter assembly B) and the lower boundary (the overlapping surface between the front panel body 1 and the front panel lower main board assembly F) of the low-vehicle front panel assembly A, and by adjusting the water gutter and the lower cross beam of the windshield and the differentiation of the front panel lower main board (only the punching mold is different), the universality of the front panel assembly A is achieved.

[0032] Furthermore, the dash crossbeam assembly 2 includes a dash crossbeam body 20, a dash crossbeam left connecting plate 21 and a dash crossbeam right connecting plate 22. The dash crossbeam body 20 is connected to the dash panel body 1 and the vehicle body structure. The dash crossbeam left connecting plate 21 and the dash crossbeam right connecting plate 22 are both connected to the ends of the dash crossbeam body 20, the dash panel body 1 and the vehicle body structure.

[0033] The dash crossbeam body 20 and the dash crossbeam left connecting plate 21 and dash crossbeam right connecting plate 22 at both ends are assembled to corresponding positions of the dash panel body 1 by welding according to the determined upper and lower boundaries of the dash panel assembly A.

[0034] Furthermore, the left connecting plate 31 of the front panel and the right connecting plate 32 of the front panel have the same structure and are symmetrically arranged at the two ends of the front panel body 1; the left connecting plate 21 of the front panel cross beam and the right connecting plate 22 of the front panel cross beam have the same structure and are symmetrically arranged at the two ends of the front panel cross beam body 20.

[0035] In the structure of the dash panel assembly A, the left and right connecting plates in the dash cross beam assembly 2 and the left and right connecting plates of the dash panel have the same functions, and the only difference between them is the position difference in the arrangement in the dash panel assembly A. Therefore, they are set to the same structure and can be shared, thereby improving the commonality of their components.

[0036] See also Figures 1 to 3 In one embodiment, a connection structure of a component mounting surface 4 is provided on the front panel body 1, and the connection structure includes a punching hole opened on the front panel body 1, and the vehicle component on the component mounting surface 4 changes its height position according to the punching hole on the front panel body 1.

[0037] Furthermore, the component mounting surface 4 includes an air-conditioning component mounting surface 41, a brake component mounting surface 42 and a component mounting surface 43; wherein, the air-conditioning component mounting surface 41 is provided with an air-conditioning device of the vehicle component, and the air-conditioning device is provided with a main air outlet and a circulating air outlet through the punching hole on the front panel body 1; the brake component mounting surface 42 is provided with a braking device of the vehicle component, and the braking device includes a brake pedal and a brake system control box ONEBOX, and the lever of the brake pedal passes through the punching hole on the front panel body 1; the component mounting surface 43 is provided with a steering device of the vehicle component, and the steering device includes a steering column and a dust cover, the steering column passes through the punching hole on the front panel body 1, and the dust cover covers the punching hole through which the steering column passes through the front panel body 1.

[0038] In this embodiment, vehicle components installed in the area of ​​the front panel assembly A, such as the vehicle's air-conditioning vents, the lever mechanism of the brake pedal, and the steering column mechanism, need to pass through the front panel assembly A between the engine cabin and the cockpit. In the structure of the front panel assembly A, by setting the size of the punching holes, the height-adjustable function can be achieved while adapting to the assembly requirements of the vehicle components, thereby realizing the universal strategy of the front panel assembly A in the electric architecture platform.

[0039] Taking a high vehicle as an example, the air conditioning assembly installation surface 41 reserved on the dash panel body 1 can realize the requirement of the center air conditioner to move down by a maximum of 20 mm in height. The brake assembly installation surface 42 reserved on the dash panel body 1 and the dash brake reinforcement plate 6 can realize the requirement of the brake pedal and the brake system control box ONEBOX to move down by a maximum of 20 mm in height. The assembly installation surface 43 reserved on the dash panel body 1 and the dash cross beam body 20 can realize the requirement of the steering column and the dust cover to move down in height. Similarly, the outer contour of the dust cover protection plate 5 remains unchanged, and the flange hole can be punched according to the axial direction of the steering column.

[0040] See also Figure 1 to Figure 2 In one embodiment, a dust cover protection plate 5 is further included, which is arranged on the back side of the front panel body 1 and on the outside of the dust cover, and the front panel cross beam body 20 is provided with the same punching holes as those on the front panel body 1.

[0041] Furthermore, it also includes a front brake reinforcement plate 6, which is connected to the front face of the front panel body 1 and is located at the place where the lever of the brake pedal passes through the punching hole on the front panel body 1, and the front brake reinforcement plate 6 is provided with the same punching hole as that on the front panel body 1.

[0042] Furthermore, the front panel assembly A is formed by sequentially welding the front panel cross beam left connecting plate 21, the front panel cross beam right connecting plate 22, the dust cover protection plate 5, the front panel cross beam body 20, the front panel brake reinforcement plate 6, the front panel left connecting plate 31, and the front panel right connecting plate 32 on the front panel body 1.

[0043] The dust cover protection plate 5 and the front brake reinforcement plate 6 are respectively determined according to the punching positions of the lever mechanism of the steering column and the brake pedal on the front panel assembly A, so they are located between the upper and lower boundaries of the front panel assembly A. In the structure of the front panel assembly A, the components are used as welding levels in the order listed, which facilitates the consistency of welding processing of the components of the front panel assembly A and its semi-finished products at different bases.

[0044] See also Figures 4 to 5 The present invention also provides a universal cabin assembly based on an electric architecture platform, comprising: a front panel assembly A, a water trough assembly B, a windshield lower cross beam assembly C, a left front longitudinal beam assembly D, a right front longitudinal beam assembly E and a front panel lower main board assembly F; wherein, the upper boundary of the front panel assembly A is determined according to the overlapping surface between the front panel assembly A and the water trough assembly B, and the lower boundary of the front panel assembly A is determined according to the overlapping surface between the front panel assembly A and the front panel lower main board assembly F.

[0045] Furthermore, the forming sequence of the cabin assembly includes: welding the front panel assembly A and the front panel lower main board assembly F into assembly one; welding the right front longitudinal beam assembly E and the left front longitudinal beam assembly D on assembly one to form assembly two; welding the water trough assembly B on assembly two to form assembly three; welding the windshield lower cross beam assembly C on assembly three to form the cabin assembly; wherein, the right front longitudinal beam assembly E and the left front longitudinal beam assembly D are simultaneously assembled and welded.

[0046] In this embodiment, the cabin assembly of the electric architecture platform is welded from eight assemblies including the front panel assembly A and the front panel lower main board assembly F. To ensure the welding consistency of the cabin assembly in different manufacturing bases, the welding level of the cabin assembly is fixed and the components are connected by spot welding. The above forming sequence is to illustrate the welding level of the cabin assembly.

[0047] In summary, the present invention provides a universal front panel assembly A and a cabin assembly based on an electric architecture platform. By determining the upper boundary (the overlapping surface of the front panel body 1 and the water gutter assembly B) and the lower boundary (the overlapping surface of the front panel body 1 and the front panel lower main board assembly F) of the front panel assembly A based on the electric architecture platform vehicle model, and by adjusting the differentiation of the water gutter assembly B, the windshield lower cross beam assembly C and the front panel lower main board assembly F (only the punching mold is different), the universality of the front panel assembly A is achieved, and the development cost of parts molds and the cost of tooling and fixtures are reduced, thereby reducing the cost of the entire vehicle.
