FASTENING SYSTEM, PRIMARILY FOR TWO OR MORE BATTERIES

ABSTRACT

The present invention relates to a fastening system including fastening devices for

5

vehicle batteries, primarily for fastening two batteries near each other in a battery box with at least two side walls in a heavy commercial vehicle, such as a truck or a bus.

BACKGROUND ART

Heavy commercial vehicles, like trucks or buses, are normally equipped with two batteries for providing enough electrical energy to the electrical system of the vehicle. Such batteries are comparatively large and heavy and as especially trucks often are driven on uneven/rough roads/grounds causing high/strong vibrations in

15

the vehicle, negative mechanical forces will act on the batteries. High vibration levels exert considerable stresses on the fastening devices for the batteries and in turn to the batteries themselves and this may eventually displace and/or damage the batteries. It is therefore very important that the batteries are securely fixed in their primarily installed positions.

20

The mentioned problems are well known and different solutions have earlier been proposed to solve the problems.

The patent document GB2121233 (Kirk et al) describes for example a battery case

25

provided with a set bars or edges (13) are integrally cast in the lower part of the battery housing, and arranged for co-operating with hold-down means installed in the vehicle. This solution requires a very specific design of the battery and is not possible to use for various sizes/makes of normal batteries.

US20100136425 (Gau et al) illustrates a battery fastening design for facilitating exchanging a used battery in short time. A fixing structure is erected from a base of

a battery assembly structure, and a pressing portion and a releasing opening are disposed at a top edge of the fixing structure. The construction is provided with a handle (23) for lifting and locating the battery (20) on a base (10) when the handle is in gripping position. Several electrode terminals (11) are provided on the base, and a fixing structure (12) is arranged with a pressing portion (125). This design is

5

unique and all components included are designed for one type of battery only.

Other solutions to this problem exist in the market but none of these prior art devices illustrates a fastening device that keeps large batteries safe in place when exposed to heavy vibrations.

TECHNICAL SOLUTION

One important object of the present invention is to solve the above mentioned

15

problems and to provide a simple/cheap and easy to adapt fastening system/device keeping the batteries in their intended positions without exerting a large vertical force on the upper surface of the battery housing. The fastening system principally comprises of a set of fastening elements positioned in the battery box. The fastening elements are pre-shaped blocks made of e.g. injection cast plastic or of aluminum or
