Automobile storage battery holder assembly

Abstract

The invention discloses an automobile storage battery holder assembly which comprises a lower support, an upper support and an upper support reinforcing piece. The cross section of the lower support is of an M shape. A first lap joint turned edge and a second lap joint turned edge are arranged on the two sides of the lower support respectively. The lower support is provided with a downward-concave face. The top face of the lower support is an inclined face, wherein the included angle between the top face of the lower support and the downward-concave face ranges from 20 degrees to 45 degrees. The top face of the upper support is of a T shape. Two concave portions are formed in the two sides of the upper support respectively. The bottom faces of the two concave portions are located in the same plane and incline relative to the top face of the upper support. Upper support installation holes are formed in the bottom faces of the two concave portions. The top face of the T-shaped upper support is provided with a downward-concave first U-shaped reinforcing rib and provided with a first storage battery installation hole. The upper support reinforcing piece is of a T shape, the two ends of the upper support reinforcing piece are provided with second storage battery installation holes and provided with downward-concave second U-shaped reinforcing ribs overlapping with the first U-shaped reinforcing rib. The automobile storage battery holder assembly has high structural strength and modal, occupies small space in a cabin and is convenient to install.

Description

technical field [0001] The invention belongs to an automobile accessory mounting part, and in particular relates to an automobile storage battery bracket assembly. Background technique [0002] The car battery is an indispensable part of the car. Its function is to store the limited electric energy, release the electric energy when the car is started, and convert chemical energy into electric energy. [0003] The car battery is fixed on the vehicle body through the battery bracket assembly. Most of the traditional car battery brackets are stamped from metal materials that are easier to form. The connection method is generally to fix the battery bracket on the car longitudinal beam only through solder joints. This kind of battery bracket has simple structure, poor strength, and low modality. Very easy to crack. According to the layout of the car engine room, the occupied space of the battery bracket structure, the influence on the installation channels of other parts and th...

AI Technical Summary

Problems solved by technology

The battery fixing bracket assembly with this structure has the following problems: (1) The modal value of CAE analysis is low, and the strength of the bracket assembly is weak; (2) The lower bracket welded with the upper bracket and the boss member is installed on the side beam of the cabin by bolts On the other hand, the bolt installation operation space is extremely small (because the engine has been placed in the engine room), which may affect the safety distance from the surrounding parts, and its installation is inconvenient, the installation efficiency is low, and it is easy to affect the loading cycle; (3) Force distribution Uneven, in the crash test, it will cause the cabin side beam to deviate from the longitudinal direction of the car in the direction of energy absorption
