Description

Hand held power machine, especially rechargeable rig
Technical field
The present invention relates to a kind of hand held power machine, for example rechargeable rig according to claim 1 preamble.
Background technology
In DE 20 2,006 004 934 U1, described a kind of rechargeable rig, this rechargeable rig has the electric drive motor that is used to drive tool fitting in a housing, and wherein, this CD-ROM drive motor is powered through a battery.This electric drive motor is arranged in the top of housing, and a handgrip is connected on this top with an angle, and this handgrip also is used to hold battery.In addition, this housing is provided with a support foot, and this support foot is connected on the handgrip in a side that deviates from top.The integrated function element that is used to control and monitor hand held power machine in this support foot.These function element comprise the ken of the light emitting source that is used to illuminate the workspace and the charged state that is used to show battery.
Be noted that under the situation of integrated functionality element shell stability can be owing to inserting that the light that supplies light emitting source penetrates and supplying to be used to show the dead slot that the ken of charged state is used and die down significantly.In addition; Function element in other words the ken must protect support foot to avoid externalities fully with the zone in the ejaculation zone of the light that is used for light emitting source, this is for example through corresponding strong enforcement covers and realizes in the ken or in the ejaculation zone that is used for light emitting source.
Summary of the invention
Task of the present invention is, so constructs a hand held power machine with simple structural measure, makes to be integrated in the function element quilt protection sufficiently in the hand held power machine and to guarantee advantages of higher stability simultaneously.
Characteristic with claim 1 solves this task according to the present invention.Dependent claims provides the expanded configuration that meets purpose.
Hand held power machine according to the present invention relate in particular to an electric motor drive, the equipment of the battery that is used to supply power, for example rechargeable rig or hammer drill is equipped with preferably.This hand held power machine has a housing, and this housing comprises drive unit housing parts, handgrip and the arc handle that is used to hold drive unit.Not only handgrip but also arc handle extend with respect to the drive unit housing parts angledly, and wherein, arc handle is positioned at the front on machine direction, and handgrip is positioned at the back.Deviating from the side of drive unit housing parts, arc handle and handgrip interconnect through a common pin zone, and this pin zone is the part of housing equally preferably.Therefore, drive unit housing parts, arc handle, handgrip and pin zone constitute one around quadrangle, especially trapezoidal, it is convergent towards the pin zone.In the pin zone, hold functional unit, promptly be used to illuminate lighting unit and the charged state display unit of the workspace of hand held power machine, the charged state display unit of optics especially.
Since arc handle and handgrip through pin regional and through thus obtained around being connected of shell structure of sealing; People obtain advantages of higher stability when improving ergonomics, because this hand held power machine can also can be gripped and handle on handgrip on arc handle.Lighting unit in the pin zone and charged state display unit have one from the workspace of hand held power machine relatively large spacing and therefore protected relatively goodly and avoid externalities.Simultaneously, lighting unit is arranged in the pin zone in the position of an exposure, so that guarantee to illuminate the workspace.
Be provided with according to a favourable embodiment, the charged state display unit has a viewing area, and this viewing area is integrated in the upper side in the pin zone between arc handle and the handgrip.Therefore this viewing area be positioned at around sealing shell structure inside and avoided mechanical damage and make dirty by protection.If this viewing area alternatively is installed in the side in pin zone, especially tilt with respect to upper side in the side of an angle one, the vision accessibility becomes easy so.
Meet the embodiment of purpose according to another, the pin zone has one and protrudes in arc the section that is positioned at the front, and the lighting unit that is used for illuminating the workspace is installed in this section.The outstanding forward section in this pin zone makes and reduces the danger of making dirty with mechanical damage from the enough spacings of cutter on the one hand, can illuminate the workspace directly, without barrier on the other hand.With respect to the tool fitting of hand held power machine, the section that points to forward in pin zone is misplaced backward, makes when processing work, for example on a wall, not have the regional danger of bumping against with workpiece or this wall of pin.
This pin zone advantageously has and is used to hold battery, for example the device of changeable type battery.At this, said device can especially constitute through insertion in the pin zone and/or grafting opening.This pin zone can constitute a support section simultaneously, and hand held power machine can prop up and be placed on this support section.Because battery is contained in the pin zone, this hand held power machine have one in height roughly be positioned at the center center of gravity, this has improved in the ergonomics of handling and gripping aspect the hand held power machine.
This charged state display unit can comprise a plurality of LED (light emitting diode), and these LED are arranged on the electronic circuit board.A plurality of LED are set have advantage, promptly on the one hand can obtain bigger luminous intensity, this charged state display unit can show with the mode of Discrete Change through connecting different LED on the other hand.What meet purpose is, is provided with photocon, and these photocons conduct to the viewing area in the pin zone with the light of LED.
Meet the embodiment of purpose according to other, the viewing area of charged state display unit (in this viewing area, can discern current charged state) has a plurality of window faces, and the quantity of window face is consistent with the quantity of lighting unit (LED usually).These window faces are the part of unique, a continuous display window preferably, and this display window is loaded in the housing wall in pin zone.The surrounding edge that for example applies with color is used to be divided into different window faces.Look current charged state and decide, in these window faces, demonstrate the light of the light source of varying number.
What meet purpose is, integrated lens in the pin zone, and these lens are parts of lighting unit, illuminate the workspace of hand held power machine through this lighting unit.At this, these lens have dual-use function: its protects the light source of lighting unit on the one hand, and it makes the light pack and light is redirect on the workspace on the other hand.In case of necessity, the light source of lighting unit also is embodied as LED.
Description of drawings
Other advantages draw from other claims, description of drawings and accompanying drawing with the embodiment that meets purpose.Accompanying drawing illustrates:
Fig. 1 illustrates the three-dimensional view of the hand held power machine that is embodied as rechargeable rig; The housing of this hand held power machine comprises arc handle and handgrip that is positioned at the back that is positioned at the front; Wherein, arc handle extends with respect to the drive unit housing parts with handgrip angledly and is connected through the pin zone in a side that deviates from the drive unit housing parts.
Fig. 2 illustrates the detailed view of charged state display unit, and this charged state display unit is integrated in the pin zone between arc handle and the handgrip,
