A pull-out installation structure for electric components of new energy vehicles

Abstract

The invention discloses a pull-out installation structure for electric components of a new energy vehicle, comprising a base and a transition bracket connected with the electric components. The top of the transition bracket is provided with a dovetail groove, and the bottom of the transition bracket is provided with a through hole , A pin shaft is arranged on the upper part of the base, and a pre-embedded bolt is arranged at the bottom of the base. During assembly, the dovetail groove is matched with the pin shaft, and the pre-embedded bolt passes through the through hole and locks the transition bracket with a nut. By using the dovetail groove of the transition bracket to match the pin shaft of the base, when using the embedded bolt to lock the transition bracket, the pre-tightening force of the bolt is fed back to the dovetail groove, so that the dovetail groove and the pin shaft are tightly fitted, thereby realizing At the same time, the dovetail groove has the function of guiding and positioning. The dovetail groove and the pin shaft of the base cooperate to realize the positioning of the electrical device during the pulling process; the dovetail groove and the pin shaft can be tightly fitted to effectively avoid the entire installation. The structure vibrates.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and designs an electrical component installation structure for new energy vehicles, and more specifically relates to a pull-out installation structure for new energy vehicle electrical components. Background technique [0002] New energy vehicle systems usually include several electrical components, such as controllers, converters, and power batteries. In order to facilitate the use and maintenance of automobiles, electrical components are usually installed centrally, so the installation and maintenance space of electrical components is compressed. Therefore, it is a reasonable solution to facilitate the maintenance and repair of electrical components by installing the electrical components in a pull-out manner. [0003] Since most of the electrical components of new energy vehicles are fine electronic components, if the structure vibrates, the service life of the electrical components will ...

AI Technical Summary

Problems solved by technology

[0003] Since most of the electrical components of new energy vehicles are fine electronic components, if the structure vibrates, it will greatly affect the service life of the electrical components and may cause problems that affect safety

In the existing public technology, the pull-out installation structure usually includes guide rails and chute, and in actual installation, if it is necessary to ensure that the electrical components do not vibrate with the movement of the vehicle after being installed on the installation structure, it is necessary to improve the guide rail and chute in the pull-out installation structure. The machining accuracy to improve the installation accuracy, which greatly increases the processing cost
