RU43225U1 - DEVICE FOR FASTENING NODES AND UNITS OF THE CENTRAL PART OF THE INSTRUMENT PANEL - Google Patents

Abstract

The utility model relates to the field of transport engineering, namely to the dashboards of a passenger car. The objective of the utility model is to increase the rigidity of fastening the instrument panel, improve the manufacturability of the assembly, reduce the complexity of manufacturing brackets and fix them on the cross member. The mounting device for assemblies and assemblies of the central part of the instrument panel is a U-shaped bracket (1) with curved protrusions bent by 90. In the central part of the bracket, a place for mounting electronic blocks through mounting holes (3) is organized, and holes are made on the flanges (4) (5) for attaching the wiring harness. On the right (6) and left (7) elements of the bracket there is a mounting hole (8) and an installation groove (9) through which the nut (11) and pin (12) fix the rack (10) relative to the bracket. The bracket is attached to the crossbar of the instrument panel along the edge of the flange (16) and the reinforcing element (22) with a welding joint.

Description

The utility model relates to the field of transport engineering, namely to the structures of the supporting elements of the dashboards of a car.

A technical solution is known for the cross member of the vehicle instrument panel (patent RU No. 33349 priority of 03/12/2003), selected as the closest analogue. The constructive solution of the central part of this utility model is based on the structural features of the cross member, which is two stamped steel parts welded together to form a box section. A large number of brackets and landing holes were used to fasten the assemblies and assemblies of the instrument panel and the panel itself.

The above design solution does not meet modern requirements for noise and vibration due to insufficient rigidity of fastening.

The objective of the utility model is to increase the rigidity of fastening the instrument panel, improve the manufacturability of the assembly, reduce the complexity of manufacturing brackets and fix them on the cross member.

To solve this problem, we propose the design of a steel universal U-shaped bracket with cutouts, bends, holes, welded nuts, designed to attach nodes and assemblies to the central part of the instrument panel and the panel itself.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition of “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, feasibly, reproducibly, therefore, meets the patentability condition "industrial applicability".

The essence of the technical solution is shown in the photographs and diagrams:

Figure 1 - General view;

Figure 2 is a complete assembly.

The mounting device for assemblies and assemblies of the central part of the instrument panel is a U-shaped bracket (1) with figured protrusions (2), bent by 90. In the central part of the bracket (1) there is a place for mounting electronic blocks, and the mounting holes of the blocks are automatically located opposite corresponding holes (3) of the bracket (1), which facilitates the process of connecting with fixing screws.

Flanges (4) with holes (5) are bent so that they define the path of the wire harness, which is fixed with fasteners in the holes (5).

The right (6) and left (7) element of the bracket (1) are mirrored, in the middle part of which there is a mounting hole (8) and an installation groove (9) for fastening the rack (10), which ensures reliable fastening of the rack (10) with one bolt. A nut (11) and a pin (12) are welded to the stand (10). The stand (10) is installed on the inside of the element (6) of the bracket (1), and the pin (12) enters the groove (9), and a bolt (13) is screwed into the nut (11) through the hole (8), which allows the stand to be fixed (10) in a given direction and secure against rotation around the axis of the bolt (13).

An installation groove (14) is made in the upper part of the element (6) of the bracket (1), repeating the external contour of the cross member (15) of the instrument panel and passing to the flange (16) with a welded nut (17) for fastening the instrument panel. Along the edge (18) of the flange (16) and the groove (14), the bracket (1) is welded to the cross member (15).

At the end of the bracket (1) there is a flange (19) with a welded nut (20) for fastening the car heater. In turn, the flange (19) has a reinforcing element (22), which closes to the cross member (15) along the edge (23) with a welding joint.

The oval hole with a flange (24) performs the function of facilitating and strengthening the bracket (1).

Thus, the bracket (1) provides fastening on the cross member (15) of the heater, two electronic units, the wiring harness and the instrument panel.

The design of the universal bracket provides high accuracy of the relative positioning of the mounting and installation holes, ease of installation, ease of construction and high spatial rigidity.
