Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly relates to an installation assembly for a truck airbag ECU. Background Technique

[0002] The automobile airbag system is an important part of the automobile passive safety system, and its main function is to protect the occupants through a rapidly inflated airbag when the vehicle collides. Among them, the airbag ECU (electronic control unit) is the core component of the airbag system, responsible for processing the information input by various sensors and judging whether to trigger the airbag according to a preset algorithm. Due to its large volume and weight, trucks often cause serious consequences in collision accidents. Therefore, the performance of the truck airbag system is particularly important. The airbag ECU is greatly affected by the surrounding environment, and the reasonable layout and installation of the truck airbag ECU directly determine the reliability of the airbag.

[0003] The existing design of the passenger car airbag ECU is mainly arranged under the central passage armrest box. For commercial vehicles, considering the aesthetics of the cab and the human-machine comfort, the design without a middle passage armrest box is adopted, and the airbag ECU is arranged on the front floor. The airbag ECU is very sensitive to acceleration signals, and its installation requirements need to consider that the installation position has sufficient stiffness and a relatively high use modal frequency, and resonance should not occur at this position during normal use. For example, when directly installed on the front floor, the modal of the front floor is low, and the vibration signal is likely to cause the airbag to explode accidentally, scaring or injuring the occupants. At the same time, directly installing on the front floor is not conducive to moisture or waterproofing, affecting the use function of the airbag ECU. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an installation assembly for a truck airbag ECU.

[0005] The installation assembly for a truck airbag ECU provided by the utility model adopts the following technical solutions:

[0006] An installation assembly for a truck airbag ECU includes an installation bracket for installing the airbag ECU body. The installation bracket is fixed on the front floor. A boss for installing the airbag ECU body protrudes upward on the installation bracket. A connecting bracket assembly for connecting with the instrument pipe beam bracket is also arranged on the installation bracket.

[0007] Further, the connecting bracket assembly includes lower connecting brackets arranged on both sides of the installation bracket, an upper connecting bracket connected to the instrument pipe beam bracket, and a middle connecting bracket for connecting the lower connecting brackets and the upper connecting bracket.

[0008] Furthermore, connecting plates for connecting with the lower connecting bracket are arranged on both sides of the mounting bracket.

[0009] Furthermore, two upper connecting brackets are symmetrically arranged, and the lower connecting bracket, the upper connecting bracket and the instrument pipe beam bracket form a frame structure.

[0010] Furthermore, both the lower connecting bracket and the upper connecting bracket are connected to the front floor.

[0011] Furthermore, a floor transverse reinforcing longitudinal beam and a floor longitudinal reinforcing longitudinal beam perpendicular to each other are arranged on one side of the front floor facing away from the airbag ECU body.

[0012] Furthermore, floor rear reinforcing longitudinal beams are arranged on both sides of the rear end of the front floor and located on both sides of the floor longitudinal reinforcing longitudinal beam.

[0013] Furthermore, floor front reinforcing longitudinal beams are arranged at both ends of the floor transverse reinforcing longitudinal beam at the front end of the front floor.

[0014] In summary, the present utility model includes at least one of the following beneficial effects:

[0015] 1. The mounting bracket of the airbag ECU can greatly improve the mounting stiffness and natural frequency of the mounting position of the airbag ECU through the design of the floor cross beam, the floor longitudinal beam and the mounting boss of the bracket itself, meeting the mounting requirements of the airbag ECU;

[0016] 2. The U-shaped mounting bracket of the airbag ECU installs the airbag ECU and the lower connecting bracket of the instrument pipe beam at the same time, which can save the connecting bracket between the instrument pipe beam assembly and the floor, facilitating the lightweight design of the whole vehicle;

[0017] 3.
