Es sind eine Vielzahl von handgeführten Arbeitsgeräten bekannt, die als Antriebsmotor einen Elektromotor aufweisen, und bei denen als Energieversorgungseinheit ein Akkupack dient. Ein solches Arbeitsgerät ist beispielsweise in
Eine solche Anordnung ist bei verschiedenen Gerätetypen vorteilhaft, aber bei anderen Geräten unpraktisch, da ein angebauter Akku die Handhabung behindern kann.Such an arrangement is advantageous in different types of devices, but impractical for other devices, since an attached battery can hinder handling.

Der Erfindung liegt die Aufgabe zugrunde, ein handgeführtes Arbeitsgerät mit einem elektrischen Antriebsmotor der eingangs genannten Gattung zu schaffen, bei dem eine einfache Montage der elektrischen Bauteile und günstigere Anordnung des Akkupacks gegeben sind.The invention has for its object to provide a hand-held implement with an electric drive motor of the type mentioned, in which a simple assembly of the electrical components and more favorable arrangement of the battery pack are given.
Diese Aufgabe wird durch ein handgeführtes Arbeitsgerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a hand-held implement with the features of
Mit der vorliegenden Erfindung wird erreicht, dass die elektrischen Bauteile an einem Systemträger zusammengefasst und als Baugruppe in das Gehäuse des Arbeitsgeräts eingesetzt werden, wodurch die Montage wesentlich vereinfacht wird. Eine Funktionskontrolle der Baugruppe ist bereits vor der Montage im Gehäuse möglich, so dass Fehler frühzeitig festgestellt und behoben werden können. Weiter ist es von Vorteil, dass der Akkupack vollständig in dem Gehäuse des Arbeitsgeräts aufgenommen werden kann und nicht an irgendeiner Stelle störend hervorsteht.With the present invention it is achieved that the electrical components are combined on a system carrier and used as an assembly in the housing of the working device, whereby the assembly is substantially simplified. Functional inspection of the module is already possible before installation in the housing, so that errors can be detected and remedied early. Further, it is advantageous that the battery pack can be completely accommodated in the housing of the working device and does not protrude at any point disturbing.
Der Akkuschacht ist zwischen zwei von einem Boden aufragenden parallelen Wänden bzw. Wandteilen des Systemträgers gebildet ist, wobei der Boden mit den Wänden bzw. Wandteilen die Form eines U aufweisen. Durch diese Ausgestaltung wird die Form des Akkuschachts hinreichend definiert bei minimalem Einsatz des Materials für den Systemträger. An den dem Boden abgewandten Enden der Wandteile ist eine Umfangsrand angeordnet, der eine Einführöffnung des Akkuschachts umgibt. Eine solche Ausgestaltung ist von Vorteil, wenn der Systemträger in einem Gehäuse angeordnet wird, das den Akkuschacht nicht seitlich begrenzt, so dass der Umfangsrand eine seitliche Führung des Akkupacks bietet. The battery compartment is formed between two parallel walls or wall parts of the system carrier which rise from a floor, wherein the floor with the walls or wall parts has the shape of a U. With this configuration, the shape of the battery compartment is defined sufficiently with minimal use of the material for the system carrier. At the end remote from the bottom of the wall parts , a peripheral edge is arranged , which surrounds an insertion opening of the battery compartment. Such a configuration is advantageous if the system carrier is arranged in a housing which does not delimit the battery compartment laterally, so that the peripheral edge offers a lateral guidance of the battery pack.
Vorzugsweise besteht der Systemträger aus einem Kunststoff und wird als Spritzgussteil einstückig ausgeführt. An diesem Spritzgussteil können die Aufnahmen für die elektrischen Bauteile sowie für die elektrischen Leitungen vorgesehen werden, so dass eine größtmögliche Integration möglich ist. Es ist außerdem zweckmäßig, dass an den zueinander gewandten Seiten der Wände, die den Akkuschacht begrenzen, Führungsstege angeordnet sind, die zwischen dem Akkupack und den Wänden einen Spalt bilden. Auf diese Weise kann bei entsprechender Führung eines Kühlluftstroms innerhalb des Gehäuses auch die Kühlung des Akkupacks erfolgen.Preferably, the system carrier is made of a plastic and is designed as an injection molded part in one piece. At this injection molded part, the receptacles for the electrical components and for the electrical lines can be provided, so that the greatest possible integration is possible. It is also expedient that on the mutually facing sides of the walls that define the battery compartment, guide webs are arranged between the battery pack and the walls form a gap. In this way, with appropriate guidance of a cooling air flow within the housing and the cooling of the battery pack can be done.
Um ein unbeabsichtigtes Lösen des Akkupacks aus dem Systemträger zu verhindern, ist es von Vorteil, an den dem Boden abgewandten Enden der Wandteile Halteelemente zur Fixierung des Akkupacks vorzusehen. Die elektrischen Bauteile umfassen vorzugsweise zumindest eine elektronische Steuerung oder Regelung und eine Schalteinrichtung bzw. einen Schalter. Die Schalteinrichtung beinhaltet dabei in vorteilhafter Weise einen steuerbaren Widerstand, so dass die Größe der einzuspeisenden Spannung veränderbar ist. Die elektronische Steuerung sorgt für einen optimalen Betrieb des Elektromotors unter Berücksichtigung der jeweiligen Parameter. Selbst-kann anstelle der Steuerung auch eine elektronische Regelung vorgesehen sein. Die Ansprüche erstrecken sich daher auch auf Anordnungen, in denen eine Regelung vorgesehen ist.In order to prevent inadvertent release of the battery pack from the system carrier, it is advantageous to provide at the end remote from the bottom of the wall parts holding elements for fixing the battery pack. The electrical components preferably comprise at least one electronic control or regulating device and a switching device or a switch. The switching device advantageously includes a controllable resistor, so that the size of the voltage to be fed in is variable. The electronic control ensures optimum operation of the electric motor, taking into account the respective parameters. Self-may be provided instead of the controller and an electronic control. The claims therefore also extend to arrangements in which a regulation is provided.
Darüber hinaus ist es von Vorteil, dass die elektrischen Leitungen zu einem Kabelbaum zusammengefasst sind, der zumindest teilweise in Ausnehmungen des Systemträgers angeordnet ist. Ein vorgefertigter Kabelbaum vereinfacht die Montage und kann in einfacher Weise in den Ausnehmungen des Systemträgers gehalten werden. Außerdem ist es zweckmäßig, an dem Systemträger elektrische Leitungen mit Anschlüssen zur Verbindung mit dem Antriebsmotor vorzusehen. Der Systemträger mit allen elektrischen Bauteilen wird in das Gehäuse des Arbeitsgeräts eingesetzt, so dass anschließend nur noch die Verbindung zum Antriebsmotor mit Hilfe der Anschlussklemmen vorzunehmen ist.Moreover, it is advantageous that the electrical lines are combined to form a cable harness, which is at least partially disposed in recesses of the system carrier. A prefabricated wiring harness simplifies assembly and can be easily held in the recesses of the system carrier. In addition, it is expedient to provide electrical lines with connections for connection to the drive motor on the system carrier. The system carrier with all electrical components is inserted into the housing of the implement, so that subsequently only the connection to the drive motor must be made with the aid of the terminals.
Damit die elektrischen Bauteile nicht jeweils einzeln an dem Systemträger angebracht werden müssen, wird es als vorteilhaft angesehen, dass an dem Systemträger eine Trägerplatte vorgesehen ist, auf der die elektronische Steuerung und Anschlussstecker sowie ggf. weitere Bauteile angeordnet sind. Auf diese Weise lassen sich die elektrischen Bauteile zu einer Baugruppe zusammenfassen, die dann an dem Systemträger befestigt und mit den Kontaktelementen verbunden wird.So that the electrical components do not have to be individually attached to the system carrier, it is considered advantageous that a carrier plate is provided on the system carrier, on which the electronic control and connector and possibly other components are arranged. In this way, the electrical components can be combined to form an assembly, which is then attached to the system carrier and connected to the contact elements.
Bei bestimmten Typen von Arbeitsgeräten müssen Sicherheitsvorrichtungen vorgesehen werden, um die Bedienungspersonen in bestimmten Situationen der Handhabung vor Gefahren zu schützen. Bei solchen Geräten ist es zweckmäßig, dass die elektrischen Bauteile auch einen Schalter umfassen, der bei Betätigung eines Handschutzes die Stromversorgung vom Akkupack unterbricht.For certain types of implements, safety devices must be provided to protect operators from hazards in certain situations. In such devices, it is expedient that the electrical components also include a switch which interrupts the power supply from the battery pack upon actuation of a hand guard.
Um eine Beschädigung der Kontaktelemente zu vermeiden und ein sicheres Kontaktieren des Akkupacks zu gewährleisten, wird außerdem vorgeschlagen, dass die Kontaktelemente zur Kontaktierung des Akkupacks am Boden des Akkuschachts angeordnet sind, vorzugsweise auf einer schwimmend gelagerten Kontaktplatte.In order to avoid damage to the contact elements and to ensure a secure contact of the battery pack, it is also proposed that the contact elements for contacting the battery pack are arranged at the bottom of the battery bay, preferably on a floating contact plate.
Bei bestimmten Typen von Arbeitsgeräten kann es zweckmäßig sein, an dem Gehäuse des Arbeitsgeräts einen hinteren Handgriff vorzusehen und in diesem einen Gashebel zu lagern, der mechanisch mit der Schalteinrichtung verbunden ist. Auf diese Weise kann mit Hilfe des Gashebels die jeweils gewünschte Leistung des Antriebsmotors eingestellt werden. Zur Anordnung eines Schalters am Systemträger kann es zweckmäßig sein, an dem Umfangsrand eine Aufnahmevorrichtung für den Schalter vorzusehen. Um den Systemträger in einem Gehäuse festzulegen, das wesentlich größeren Bauraum bietet als für den Systemträger erforderlich ist, kann es zweckmäßig sein, dass an dem Umfangsrand Stützen angeformt sind, an deren freien Enden sich Befestigungsösen zur Aufnahme von Befestigungsmitteln befinden. Zum leichteren Entnehmen des Akkupacks aus dem Systemträger ist es vorteilhaft, dass am Boden des Akkuschachts eine Ausschiebevorrichtung für den Akkupack angeordnet ist. Eine solche Ausschiebevorrichtung kann beispielsweise in Form von federnden Drahtbügeln vorgesehen sein.In certain types of implements, it may be appropriate to provide a rear handle on the housing of the implement and to store in this a throttle, the is mechanically connected to the switching device. In this way, the respective desired power of the drive motor can be adjusted by means of the throttle lever. To arrange a switch on the system carrier, it may be appropriate to provide a receiving device for the switch on the peripheral edge. To set the system support in a housing that offers much larger space than is required for the system support, it may be appropriate that supports are formed on the peripheral edge, at the free ends are mounting eyelets for receiving fasteners. For easier removal of the battery pack from the system carrier, it is advantageous that a Ausschiebevorrichtung for the battery pack is arranged at the bottom of the battery bay. Such Ausschiebevorrichtung may be provided, for example in the form of resilient wire hangers.
