Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard crossbeam technology, and in particular to a dual-tube CCB central support assembly. Background Technology

[0002] The dashboard crossbeam is a crucial component of a car. Its two ends support the steering column and airbags, while the middle section supports the central air conditioning system. Therefore, the strength of the central support of the dashboard crossbeam has a critical impact on overall vehicle performance and safety. Existing automotive dashboard crossbeams employ methods such as... Figure 1 The single main beam 1' shown is typically a simple H-shaped central support 2'. This support is narrow and weak, and insufficient strength can cause the air conditioner blower to sink 2-3mm after installation, leading to interference with other components and abnormal noise. Furthermore, the central support 2' is usually directly welded to the main beam 1', which is prone to wobbling and thermal deformation during welding, resulting in poor overall strength and precision. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned technical problems, this utility model provides a dual-tube CCB central support assembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-tube CCB central support assembly, including dual main beams and a central support. The dual main beams include an upper main beam and a lower main beam, which are connected to each other to form a frame structure. The upper and lower main beams are arranged horizontally vertically. The central support includes a driver's side support, a passenger side support, an upper support, a middle support, a lower middle support, and a bottom support. The driver's side support and the passenger side support are both plate-shaped and vertically arranged on the dual main beams. The upper support and the middle support are arranged horizontally on the driver's side support and the passenger side support. Between these components, the driver's side bracket, upper bracket, passenger side bracket, and middle bracket are sequentially connected to form a frame cavity structure. The driver's side bracket, lower middle bracket, and bottom bracket are sequentially connected vertically. Both the upper end of the driver's side bracket and the upper end of the passenger side bracket have upper tube beam mounting holes, and both the driver's side bracket and the passenger side bracket are connected and fixed to the upper main tube beam at their upper tube beam mounting holes. Both the lower end of the driver's side bracket and the lower end of the passenger side bracket have lower tube beam mounting holes, and both the driver's side bracket and the passenger side bracket are connected and fixed to the lower main tube beam at their lower tube beam mounting holes. The bottom bracket is fixed to the vehicle floor.

[0005] The driver's side bracket and the passenger side bracket are symmetrically arranged. In a left-hand drive vehicle, the driver's side bracket is located on the left, and the passenger side bracket is located on the right. In a right-hand drive vehicle, the driver's side bracket is located on the right, and the passenger side bracket is located on the left.

[0006] Both the driver's side bracket and the passenger side bracket have a hollow structure, which allows for localized weight reduction of the bracket.

[0007] Both the driver's side bracket and the passenger side bracket have a flanged structure, and the flanged structure around the driver's side bracket and the passenger side bracket can strengthen the structure of the driver's side bracket and the passenger side bracket.

[0008] The lower and middle brackets and the bottom bracket are sheet-like. The widths of the driver's side bracket, lower and middle bracket, and bottom bracket are equal or approximately equal, or the widths of the driver's side bracket and bottom bracket are slightly larger than the width of the lower and middle bracket. The difference in width between the driver's side bracket and the bottom bracket depends on actual installation requirements. The width of the driver's side bracket is primarily to accommodate the installation requirements of the central air conditioning compressor and takes into account the actual installation space. The width of the bottom bracket is mainly to consider the installation dimensions at the bottom where it is fixed to the vehicle floor. The driver's side bracket, lower and middle bracket, and bottom bracket are enlarged and widened in the X-direction (width direction) to enhance strength. The driver's side area is reinforced to absorb energy during frontal and side impacts and limit the intrusion of the steering wheel and pedals, protecting occupants and improving safety.

[0009] Preferably, the width of the driver's side bracket is 145mm-160mm, the width of the lower middle bracket is 140mm-150mm, and the width of the bottom bracket is 170mm-180mm.

[0010] To improve installation accuracy, both the driver's side bracket and the passenger side bracket are connected and fixed to the upper main beam with bolts at the mounting holes of their upper tube beams.

[0011] To improve installation accuracy, both the driver's side bracket and the passenger side bracket are connected and fixed to the lower main beam with bolts at their lower tube beam mounting holes.

[0012] To increase the overall stability of the crossbeam, lower tube bushings are provided at both ends of the lower main tube beam, and each end of the lower main tube beam is fixed to the side panel of the vehicle body by a long bolt.

[0013] Preferably, each end of the lower main beam is fixed to the side panel of the vehicle body by a long hexagonal flange bolt.

[0014] The upper support is located on the side closer to the upper main beam, and the middle support is located on the side farther away from the lower main beam.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a dual-tube CCB central support assembly for supporting and installing automotive central air conditioning. The central support includes a driver's side support, a passenger side support, an upper support, a middle support, a lower middle support, and a bottom support. These supports can be connected by welding and then bolted to the dashboard crossbeam, ensuring high connection precision. The bottom support is fixed to the vehicle floor by two bolts at the front and rear. This large support provides high strength and increases the strength of the driving area, ensuring both the strength of the driving area and meeting the fixing requirements of the central support assembly. The driver's side support, upper support, passenger side support, and middle support—that is, the four supports of the central support—form a frame cavity, resulting in a stable and strong structure. This frame cavity structure can transfer and absorb collision loads, increasing the overall modal frequency of the dashboard crossbeam and preventing steering wheel vibration and abnormal noise caused by insufficient overall strength of the dashboard crossbeam. The increased overall strength of the support prevents the air conditioning blower from sinking during assembly, which could lead to interference with other components and abnormal noise. The upper and lower main tube beams of the dual main tube beams are interconnected to form a frame structure, ensuring good overall stability of the dashboard crossbeam. Attached Figure Description

Both the driver's side bracket 3 and the passenger side bracket 4 have a flanged structure 12, which can strengthen the structure of the driver's side bracket 3 and the passenger side bracket 4 around their perimeter.

[0028] The lower middle bracket 7 and the bottom bracket 8 are sheet-like. The widths of the driver's side bracket 3, lower middle bracket 7, and bottom bracket 8 are equal or approximately equal, or the widths of the driver's side bracket 3 and bottom bracket 8 are slightly larger than the width of the lower middle bracket 7.
