Definitions
- the invention relates to a battery box of a block battery for receiving at least one electrode plate having battery cell, having a base body made of plastic, which has two substantially parallel to the electrode plates end walls and two substantially perpendicular thereto extending side walls, which end and side walls in each case an upper and have a lower edge and a Eckkante forming interconnected.
- Batteries in general and block batteries in particular on the one hand and battery boxes for batteries, especially block batteries on the other hand are well known in the art, which is why it does not require a separate documentary evidence at this point.
- the battery boxes is typically rectangular in shape and has two end walls, two side walls and a bottom.
- the side walls and end walls are joined together to form corner edges.
- the battery box is on the top side, that is to say it is unlocked opposite the bottom.
- it can also be provided to close the battery box on the top side by means of a lid.
- the main body of the battery box is made of plastic, preferably
- ABS acrylonitrile-butadiene-styrene
- the battery cells of a block battery are formed from separately arranged electrode plates, wherein either the negative or the positive electrode plates are each surrounded by a micro-glass fleece.
- This nonwoven preferably also serves as a separator.
- the purpose of this micro-glass fleece is To store electrolyte.
- the electrode plates are therefore not in the electrolyte, but they are surrounded by a soaked with electrolyte fleece, which brings with it the advantage that the so-formed block battery can be used independently of days, that is also lying on the side.
- the plate packs of individual battery cells are under a certain bias so that the electrode plates are pressed against one another.
- Plastic as such, and so also polypropylene and ABS has the disadvantage that it loses rigidity both with increasing temperature and with increasing life. In the overlay of temperature and life, this effect is amplified. Particularly in the case of batteries, in addition, in the event of incorrect operation of the battery, for example during charging, overpressure within the battery box may still occur, as a result of which an additional load is exerted on the battery box.
- the JP S62 38306 Y2 finally shows a stiffening element, which engages in the final assembled state on the battery boxes formed vertical ribs.
- a battery box of a block battery of the generic type is known, wherein the end walls are each stiffened, for which purpose per end wall, a stiffening element is provided, which is U-shaped, wherein the U-legs in each case a side wall adjoining the associated end wall, which stiffening element is completely inserted into a recess provided by the base body and at least partially encapsulated by the plastic of the base body and embedded in the base body.
- stiffening element with respect to the respective end wall and the adjoining side walls is positively fixed, for which purpose the stiffening element has openings.
- an additional stiffening of the stiffening element is provided, for which purpose the stiffening element has beads.
- fastening edges are formed on the outer surfaces of the side walls, which run at an angle to the respective corner edge.
- Such a design of the battery box makes it possible to use these angled mounting edges on the one hand to arrange stiffening elements, on the other hand allow this that the stiffening elements are adjusted accordingly.
- the fastening edges are formed such that they are seen from the corner edges behind tangible so far can be arranged brackets or Klammem which protrude from a soap wall on the intermediate end wall to the other side wall and are respectively secured to the mounting edges. Due to the angled course to the corner edge, there is an area where the mounting bracket or mounting brackets can be attached, so that automatically takes place when moving continuously a strain.
- the attachment edge can thus obliquely from the upper edge to the lower edge of a Sidewall run. In the shenne of the present invention, this does not mean that they have to start or end in the area of the upper or lower edges. You can also start and end at the distance to the edge.
- the attachment edge may be formed by an edge provided by the sidewall material, for example, an edge-providing configuration of the sidewall material by a projection, a groove, and / or the like. But it can also be formed by applying a web element or for example a mold plate, which is applied centrally on a side wall element and haslubkantete side edges.
- the respective attachment edges offer gripping areas from the corner edge.
- the inventive design is suitable, for example, to replace damaged or too weak clip elements.
- a clip element can be arranged on the battery box such that it bears against a region on an end wall.
- the clamping element has areas which abut the respective side wall adjacent to the end wall. These areas have free ends and are folded accordingly, so that the bends can engage behind the mounting edges.
- Mehrfachkantept for engaging in grooves or folds beyond 90 ° for engaging in beveled mounting edges are within the scope of the invention.
- the clamping element is formed according to an advantageous proposal of metal.
- the clamping element have stiffening ribs. These can be impressions, folds, folds, beads and the like.
- the free ends of the clip elements are chamfered so that they have the same course as the attachment edges. So if a clamp element attached to the battery box, so the clip element can be pushed with the oblique free edge on the battery box until the free edges over their entire length abut the attachment edge of the side winch.
- Movements cause the clamp elements to vibrate again and again during operation. In addition, they can be further distended in the event of pressure changes.
- the battery boxes proposed by the invention can be produced with little economic effort.
- the arrangement of the clip elements on the battery boxes is eifindungshunt considerably simplified and improved, it is even loosening possible and a subsequent Nachverfestrien.
- the advantage achieved with the construction according to the invention is that a simple assembly is permitted.
- the clip element also called stiffening plate, can either be clipped onto the fastening edges provided by the battery box or pushed from above along the fastening edges into the end position. By such a shift in the height direction down a clamping of the clip element takes place on the battery box automatically. Special locking devices for fixing the position of the clamping element on the battery box is therefore not required.
- the construction according to the invention in particular also provides an automatic tolerance compensation. For production reasons, both the fastening edges provided by the battery housing and the respectively associated peripheral edges of the clamping element in their respective geometric configuration can not always be formed exactly identical.
- the seat of the clamp elements on the battery box may possibly become loose.
- the clip elements automatically retract downwards in the height direction so that a reassembled fit of the clip elements on the battery box is ensured.
- the attachment edges may be formed by forming corresponding grooves in the main body of the battery box.
- the fastening edges can also be formed by applying corresponding applications to the outside of the side walls of the battery box. This allows retrofitting even existing battery boxes. This is not possible with previously known constructions. Also, prior art designs do not allow the already described tolerance compensation.
- the embodiment of the invention provides in a synergetic manner that while ensuring proper support of the end walls in particular in the pressure case tolerance compensation possibility is given, and this with simultaneous possibility to equip existing boxes in terms of retrofitting in accordance with the invention.
