Battery with integrated shock and vibration protection features

Abstract

A vehicle battery that includes a partially hollow battery shell, shock-absorbing material, and a mounting base. The battery shell has an upper section and a stepped-in lower section, the lower section having a sidewall and a floor. The shock-absorbing material is attached to the sidewall of the lower section of the battery shell and has a lower edge that extends below the floor of the lower section. The mounting base is attached to the lower edge of the shock-absorbing material and is spaced from the floor of the lower section of the battery shell to isolate the battery shell from a vehicle surface on which it is supported.

DESCRIPTION OF EMBODIMENTS OF INVENTION

(10) The present invention provides a vehicle battery with integrated shock and vibration protection features. The battery has the same overall footprint and size as standard vehicle batteries and therefore meets all BCI℠ Battery Group Size requirements and fits within an OE battery holder without modification; has nearly the same overall volume as standard vehicle batteries and therefore does not suffer significantly from volumetric capacity limitations; and is equipped with securement features that interact with the hold down structures in OE battery holders.

(11) With the present invention, an OE vehicle manufacturer or vehicle owner can simply place the battery in an OE battery holder which utilizes the battery's hold down structures for securement and obtain all the shock and vibration protection benefits of an aftermarket battery hold-down and protection device without any of the associated fitment problems or significant reduction in volumetric capacity. As shown in the drawing figures and as described below, the integrated shock and vibration features are prominently visible on the exterior of the battery and therefore provide a visual indication of the shock and vibration features of the battery, thus providing a valuable incentive to buy and install the battery.

(12) Specific embodiments of the invention will now be described with reference to the attached drawings figures. As best shown in FIGS. 1 and 2, a battery 10 constructed in accordance with embodiments of the invention broadly comprises a battery shell 12; a flexible shock-absorbing pad 14; and a rigid mounting base 16.

(13) The battery shell 12 is shown without the shock-absorbing pad 14 and the mounting base 16 in FIG. 4. The battery shell 12 is at least partially hollow and encloses a number of conventional battery plates and/or other components found in batteries. As shown in FIG. 1, the battery shell 12 has a cover 18 and positive and negative terminals 20, 21 extending through the cover and electrically connected to the internal battery components. The battery shell may be formed of any corrosion-resistant materials and conforms to BCI℠ Battery Group Size requirements.

(14) To accommodate the integrated shock and vibration features of the present invention, the lower walls of the battery shell 12 are stepped-in to define an upper section 22 and a slightly smaller lower section 24 as best shown in FIGS. 4 and 5. The upper section 22 is generally the same length and width as a standard battery, but the lower section 24 has a decreased length and width so as to form a circumscribing channel 26 beneath the upper section, the purpose of which is described below.

(15) A specific embodiment of the upper section 22 includes left, right, front, and rear vertically-extending sidewalls, each connected to an inwardly projecting horizontally-extending ledge 28 as shown in FIGS. 4 and 5. An embodiment of the lower section 24 includes left, right, front, and rear vertically-extending sidewalls, the top edges of which intersect the horizontally-extending ledge 28 at right angles. The lower section 24 also includes a horizontally-extending floor 30 that intersects the lower edges of the side walls at a right angle. The reduced length and width of the lower section 24 as compared to the upper section 22 forms the circumscribing channel 26 beneath the upper section and adjacent the lower section.

(16) In one embodiment, the floor 30 is raised relative to the floors of similar BCI℠ batteries such that the battery shell 12 itself is shorter than regularly-sized BCI℠ batteries. This allows the shock-absorbing material 14 and the base 16 to be attached to the shell 12 without increasing the overall height of the battery 10 as compared to similar BCI℠ batteries.

(17) As best shown in FIG. 4, the battery shell 12 may also include a horizontally-extending flange 32 projecting from the lower section 24. The flange 32 is preferably spaced below the ledge 28, extends radially from the lower section, and includes a number of vertically-extending holes 34, the purposes of which are described below.

(18) The shock-absorbing pad 14 is attached to the lower section 24 of the battery shell in the channel 26 beneath the upper section 22. An embodiment of the pad 14 is formed of compressible material such as rubber and is frame-shaped as best shown in FIG. 6. In one embodiment, the pad 14 is molded with the battery shell 12 so that the material forming the pad flows through the holes 34 in the ledge 32 to help secure the pad in the channel. In other embodiments, the pad 14 may be formed separately and glued or otherwise attached in the channel 26. As best shown in FIGS. 3 and 5, the lower edge of the pad 14 extends below the floor 30 of the battery shell 12. This isolates the battery shell 12 from the mounting base 16 and the vehicle surface on which it rests as described below.

(19) The rigid mounting base 16 is attached to the lower edge of the shock-absorbing pad 14 and forms the lowermost portion of the battery 10. The shock-absorbing pad 14 spaces the mounting base 16 from the floor 30 of the battery shell so the battery shell is isolated from the mounting base and the vehicle surface on which it rests. An embodiment of the mounting base 16 is shown in FIG. 7 and includes a lower frame-shaped section 36 and an upper vertically-extending frame-shaped section 38. The underside 40 of the lower section forms a floor that rests on or in a vehicle, the floor of an OE battery holder or other mounting platform. The upper section 38 has a number of horizontally-extending holes 42. In one embodiment, the mounting base 16 is molded with the shock absorbing pad 14 so that the material forming the pad flows through the holes 42 to help secure the mounting base to the pad. In other embodiments, the mounting base 16 may be glued or otherwise attached to the pad 14.

(20) The mounting base 16 also includes hold-down structure 44 best shown in FIGS. 1, 3 and 7 for engaging corresponding hold-down structure in the OE battery holder. In one embodiment, the hold-down structure 44 includes an angled foot extending from at least one side of the mounting base for placement underneath a hold-down flange in an OE battery holder.

(21) In use, the battery 10 may be placed in an OE battery holder such that the floor 40 of the mounting base 16 rests on the floor of the OE battery holder and the hold-down structure 44 is held under corresponding hold down structure in the OE battery holder. The battery shell 12 is isolated from the mounting base 16 and hence the vehicle by the shock-absorbing pad 14 such that no mechanical pathway exists for shocks and/or vibrations to be transmitted from the vehicle to the battery shell and/or battery components housed inside the battery shell. Any shocks or vibrations that are transferred to the mounting base 16 are at least partially mitigated by the pad 14.
