Problems solved by technology

[0030] Seals machined from solid materials cannot have topographical relief, so only a limited compensation of tolerances is possible
Furthermore, in terms of flexibility, such seals often do not meet the requirements of battery manufacturers in terms of their dimensional design

Embodiment Construction

[0076] figure 1 A battery housing 1 is shown, including a seal 2 . figure 1 A battery housing 1 is shown with three basic components, namely a receptacle 3 , a cover 4 and a seal 2 in between. In principle, welded systems are also conceivable. The detachable structure ensures that: when a fault occurs inside the battery, for example, the contact points are detached or the cooling system leaks, the battery case 1 can be opened and the fault can be eliminated. In the case of welded battery housings 1 , even minor faults would have to shut down the entire expensive battery.

[0077] figure 2 A plan view of a seal 2 for a battery housing 1 is shown, comprising a base body 5, wherein the base body 5 has a profiled sealing element 6 with a sealing surface 7, which is concave-convex, wherein the profiled sealing element 6 has a first end 6 a and a second end 6 b, and at least two profiled sealing elements 6 are connected to each other at one of their ends 6 a by means of corner ...

Abstract

The invention relates to molding seal elements with angle connecting elements, in particular relates to seal elements (2) for a shell, and in particular relates to an electrochemical energy storage device for a battery shell or others. Each seal element comprises a base body (5), wherein the base body (5) is provided with molding seal elements (6) with seal surfaces (7); and the seal surfaces are in convex-concave structures, and the molding seal elements (6) are provided with first end parts (6a) and second end parts (6b). The invention aims to provide a modular seal element which combines advantages of the molding seal elements and advantages of flexible construction, so that the molding seal elements with the angle connecting elements are characterized in that at least two molding seal elements (6) at the corresponding end parts (6a, 6b) are mutually connected through the angle connecting elements (8).

Description

technical field [0001] The invention relates to a seal for housings, in particular for battery housings or for other electrochemical energy stores, the seal comprising a base body, wherein the base body has a profile with a sealing surface A sealing element, the seal has a concavo-convex configuration, and the molded sealing element has a first end and a second end. Background technique [0002] Extruded profiled sealing elements are used to seal large-area components. An example is a housing comprising a receptacle and a corresponding cover. [0003] Profiled sealing elements enable optimum mechanical design in terms of pressure and shrinkage (installation characteristics). In this way, for example, the distance between the fastening screws can be reduced regardless of the mechanical clamping force of the two workpieces. This profiled sealing element thereby enables the housing to be opened several times without twisting ("wavy plate phenomenon"). [0004] Arranging pro...
