Embodiment Construction

[0033] In the drawings, the same reference numerals are used for the same or similar components even when repeated description is omitted for brevity.

[0034] figure 1 A perspective view of the battery holder 1 is shown. The battery holder 1 has a pot 2 , wherein the pot 2 has an outer peripheral edge 3 and a bottom 4 . A plurality of reinforcing struts 6 are arranged in the inner space 5 of the pot 2 . In this case, the reinforcing struts 6 extend from one wall side 7 to an opposite wall side 7 .

[0035] figure 2 A plan view of the tolerance compensation element 8 according to the invention is shown. The tolerance compensation element surrounds the end of the reinforcing strut 6 with its two legs 14 . A gap 10 is formed between the end side 9 of the reinforcing strut 6 and the rear web 27 so that different manufacturing tolerances of the reinforcing strut 6 and / or the pot 2 can be compensated. The rear side 28 of the web 27 is coupled to a wall side (not shown) of th...

Abstract

The invention relates to a battery support with a tolerance equalization element. The battery support is mounted in a bottom region of an electric motor vehicle. The battery support (1) has a basin-shaped portion (2) used to hold a plurality of batteries, and selectively has a lid that closes the basin-shaped portion (2) which has a bottom portion (4) and an edge (3) that surrounding the bottom portion (4). The battery support is characterized in that the basin-shaped portion (2) is produced as a one-piece thin-walled deep drawn component made of a sheet metal blank, and reinforcement braces (6) that extend from one wall side (7) to the opposite wall side (7) are disposed within the basin-shaped portion (2). A tolerance equalization element (8) is disposed on the end side on a reinforcement brace (6).

Description

technical field [0001] The invention relates to a battery holder for an electric vehicle according to the features of the preamble of claim 1 . Background technique [0002] With the increase of electric vehicles, more and more electric vehicles are produced and allowed to run in road traffic. In contrast to motor vehicles with internal combustion engines, electric vehicles use electrical energy, which is converted into forward motion energy by the drivetrain. [0003] Batteries (also referred to as energy stores) are provided for storing the electrical energy, and these batteries have a relatively high volumetric proportion and a high dead weight relative to the motor vehicle. Usually, several such batteries are placed in the underbody region of the motor vehicle. In order to accommodate and at the same time protect the batteries, various battery holders, also called battery trays, are known from the prior art. Most of these battery holders are pot-shaped and have a cove...
