Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard crossbeam technology, and in particular to a double-tube dashboard crossbeam mounting bracket. Background Technology

[0002] The instrument panel crossbeam is the most important structural and load-bearing component of the instrument panel crossbeam assembly. It supports the human-machine interface control devices and, together with other vehicle safety control components, constitutes the vehicle safety system to protect the safety of the driver and passengers. The instrument panel crossbeam is generally composed of a single main beam with metal brackets welded to both ends to secure the entire instrument panel to the vehicle body. The metal brackets at both ends of the single main beam are fixed to the body by welding. However, due to the ease of movement and thermal deformation during the welding process, the overall strength and precision are relatively poor. Furthermore, the metal brackets are often a single-piece structure, which is thin and lacks strength. 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 double-tube instrument panel crossbeam mounting bracket.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-tube instrument panel crossbeam mounting bracket, including dual main tube beams and end brackets. The dual main tube beams include an upper main tube beam and a lower main tube beam. The upper and lower main tube beams are connected to each other through the end brackets to form a frame structure. The upper and lower main tube beams are arranged horizontally. The end brackets have a flange structure extending horizontally. The upper side of the end bracket has an upper interface, and the lower side of the end bracket has a lower interface. The end brackets are fixed to the upper main tube beam at the upper interface and to the lower main tube beam at the lower interface. An upper support piece is also fixed between the end brackets and the upper main tube beams, and a lower support piece is also fixed between the end brackets and the lower main tube beams. The upper support piece is arranged horizontally near the upper interface, and the lower support piece is arranged obliquely and extends obliquely from the middle of the end brackets to the lower main tube beams. The end brackets are fixed to the side of the vehicle body.

[0005] To make the structure more stable, the end support surface has oblique reinforcing ribs.

[0006] Preferably, the reinforcing rib is located on the surface of the end support facing the double main beam, and the reinforcing rib extends obliquely from below the upper support plate to the lower support plate.

[0007] To make the structure more stable, the reinforcing rib has a branched reinforcing section at the connection between the lower support plate and the end bracket.

[0008] The end bracket is fixed to the sheet metal on the side of the vehicle body.

[0009] To improve installation accuracy, the end bracket is fixed to the sheet metal on the side of the vehicle body with bolts.

[0010] To facilitate connection with the vehicle body, lower tube bushings are provided at both ends of the lower main tube beam. Each end of the lower main tube beam is fixed to the side panel of the vehicle body by a long bolt, thereby increasing the overall modality of the vehicle instrument panel crossbeam.

[0011] Preferably, each end of the lower main beam is fixed to the side panel of the vehicle body by a long hexagonal flange bolt.

[0012] The beneficial effects of this utility model are as follows: The dual-tube instrument panel crossbeam mounting bracket of this utility model has a flanged structure at the end bracket, which extends laterally (X-direction) to strengthen the structure; and it is further reinforced by upper and lower support plates, improving the modality of the instrument panel crossbeam in the vehicle state, avoiding systemic risks caused by insufficient strength, such as significant steering wheel vibration or collision failure that could injure occupants; the upper and lower main tube beams of the dual tube beams are interconnected with the end bracket to form a frame structure, making the instrument panel crossbeam more stable as a whole, and avoiding problems caused by steering wheel vibration and system vibration.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figure 1-3As shown, this utility model discloses a dual-tube instrument panel crossbeam mounting bracket, comprising dual main tube beams and end brackets 3. The dual main tube beams include an upper main tube beam 1 and a lower main tube beam 2, which are interconnected by the end brackets 3 to form a frame structure. The upper main tube beam 1 and the lower main tube beam 2 are arranged horizontally. The end brackets 3 have a flange structure 3-1 extending horizontally. The upper side of the end brackets 3 has an upper interface 3-2, and the lower side of the end brackets 3 has a lower interface 3-3. The end brackets 3 are fixed to the upper main tube beam 1 at the upper interface 3-2 and to the lower main tube beam 2 at the lower interface 3-3. In this embodiment, the end brackets 3 are fixed to the upper main tube beam 1 and the lower main tube beam 2 by welding.

[0020] An upper support plate 4 is fixed between the end bracket 3 and the upper main beam 1, and a lower support plate 5 is fixed between the end bracket 3 and the lower main beam 2. The upper support plate 4 is horizontally positioned near the upper interface 3-2, and the lower support plate 5 is obliquely positioned and extends obliquely from the middle of the end bracket 3 to the lower main beam 2. In this embodiment, the upper support plate 4 is fixed to the end bracket 3 and the upper main beam 1 by welding; the lower support plate 5 is fixed to the end bracket 3 and the lower main beam 2 by welding.

[0021] To enhance structural stability, the end support 3 has oblique reinforcing ribs 3-4 on its surface. The reinforcing ribs 3-4 are located on the surface of the end support 3 facing the double main beams, and extend obliquely from below the upper support plate 4 to the lower support plate 5. The reinforcing ribs 3-4 have branch reinforcing sections 3-5 at the junction of the lower support plate 5 and the end support 3.

[0022] To improve installation accuracy, the end bracket 3 is fixed to the side sheet metal of the vehicle body. Preferably, the end bracket 3 is fixed to the side sheet metal of the vehicle body with bolts.

[0023] To facilitate connection with the vehicle body, lower main beam 2 is provided with lower tube bushings 6 at both ends, and each end of the lower main beam 2 is fixed to the side panel of the vehicle body by a long bolt. Preferably, each end of the lower main beam 2 is fixed to the side panel of the vehicle body by a long hexagonal flange bolt.

[0024] Different end brackets can be connected to both ends of the dual main beam. The end bracket of this invention can be installed only at one end of the dual main beam, while the other end uses an end bracket with a different structure; alternatively, both ends of the dual main beam can use the end brackets of this invention. This invention provides a dual-tube instrument panel crossbeam mounting bracket. The end bracket 3 has a flanged structure 3-1 that extends laterally (X-direction) to strengthen the structure. It is further reinforced by upper support plates 3-2 and lower support plates 3-3, improving the instrument panel crossbeam's modal stability in the vehicle state and preventing systemic risks caused by insufficient strength, such as significant steering wheel vibration or collision-induced breakage leading to occupant injury. The upper main beam 1 and lower main beam 2 of the dual main beam are interconnected via the end bracket 3 to form a frame structure, making the instrument panel crossbeam more stable overall and preventing problems caused by steering wheel vibration and system vibration.
