[0051] The tool receiving section 140 is preferably configured to receive an insertable tool. Figure 5 (510 in the text). For example, the tool receiving unit 140 is configured to receive a plug-in tool having a round handle, a hexagonal interface, an SDS and / or an SDS-Plus interface. Figure 5 (510 in the middle). During operation, the tool receiving part 140 rotates about the rotation axis 199.
[0052] Furthermore, drive units 120 and 180 are equipped with an optional impact mechanism 150. Here, the impact mechanism 150, similar to the transmission device 120, is equipped with an operating element 152, through which the operating mode can be adjusted. For example, a turning mode, a drilling mode, and / or an impact mode can be adjusted.
[0053] According to one embodiment, the handheld power tool 100 can be mechanically and electrically connected to a battery pack 190 for operation without relying on the power grid; however, alternatively, it can also operate relying on the power grid. The battery pack 190 is arranged on the foot region 191, particularly on the underside of the finger-driven motor 180 in the foot region 191. The battery pack 190 is preferably detachably arranged on the foot region 191 via a battery pack interface. Preferably, the foot region 191 with the battery pack 190 forms the standing part of the handheld power tool 100. However, the battery pack 190 can also be fixedly integrated into the housing 105 of the handheld power tool 100.
[0054] Preferably, a directional device 175 is provided. This directional device, for example, has an operating unit 160 and at least one light-emitting element 165, 170 arranged on the housing 105. It should be noted that the directional device 175 can have any number of light-emitting elements.
[0055] Preferably, the orientation device 175 is equipped with two light-emitting elements 165 and 170. The orientation device 175 is configured to determine the selectable machining angle of the handheld machine tool 100 during its operation. Figure 3 (310, 312, 314, 316) and the actual tilt angle ( Figure 6 The current deviation between a) and is visualized. In the context of this invention, the work operation also includes the orientation of the handheld machine tool 100, during which the drive motor 180 is not activated.
[0056] Preferably, the handheld power tool 100 is equipped with a sensor for determining the actual tilt angle of the handheld power tool 100. Figure 6 (a) The sensor is preferably an accelerometer. Preferably, the accelerometer calculates the gravitational acceleration components in three mutually perpendicular spatial directions. Tilting angle ( Figure 6 a) can be determined based on the gravitational acceleration components in the three spatial directions.
[0057] Selectable machining angles ( Figure 3 The 310, 312, 314, and 316 angles can preferably be selected via the operation unit 160. Selectable machining angles ( Figure 3 310, 312, 314, and 316) are insertable tools that can be arranged in the tool receiving section 140. Figure 5 510 in the middle) and the surface of the workpiece to be machined using an insert tool ( Figure 4 Formed between 410 and (in the middle). Tilting angle ( Figure 6 a) Preferably, an insertable tool that can be arranged in the tool receiving section 140. Figure 5 510 in the middle) and the surface of the workpiece to be machined using an insert tool ( Figure 4 The orientation device 175 preferably determines the current deviation between the adjusted processing angle and the actual tilt angle in real time. Here, the current deviation is preferably visualized by at least one, preferably two, light-emitting elements 165, 170.
[0058] According to one embodiment, at least one light-emitting element 165, 170 is configured to emit at least first and second light-emitting colors ( Figure 7 720 in Figure 8 820 in Figure 9 (920 in the text). When a predetermined deviation exceeds a predetermined threshold, at least one light-emitting element 165, 170 preferably emits a first light-emitting color ( ). Figure 8 (820 in the text). Furthermore, when a predetermined deviation is less than or equal to a predetermined threshold, at least one light-emitting element 165, 170 preferably emits a second light-emitting color ( ). Figure 9 (920 in the text). According to one embodiment, the first emitting color is yellow, and the second emitting color is green.
[0059] Preferably, the threshold value is 3°, such that a maximum deviation of the set machining angle of + / - 3° about the second light color is possible. That is, in the case of a set machining angle of, for example, 30°, the at least one light element 165, 170 emits light in the second light color in an angular range of 27° to 33°. If the deviation becomes larger, i.e. exceeds the predefined threshold value of 3°, the at least one light element 165, 170 emits light in the first light color.
[0060] According to one embodiment, a second threshold value of preferably 10° can also be assigned to the second light color in a similar manner. That is, in the above example with a set machining angle of 30°, the at least one light element 165, 170 emits light in the first light color in an angular range of 20° to 27° and 33° to 40°. Here, the at least one light element 165, 170 can be switched off, for example, when the second threshold value is exceeded.
[0061] It is noted that the above-mentioned threshold values merely have exemplary character and are not intended to limit the application, but rather the first and second threshold values can also assume other values.
[0062] The at least one light element 170 is preferably arranged on an upper side 117 of the housing 105. Here, as described above, the upper side 117 is arranged facing away from the handle 115. The light element 170 is, for example, arranged on an end of the housing 105 facing away from the tool receptacle 140 or on the upper side 117. Here, the light element 170 is arranged between the operating element 122 of the transmission 120 and the end of the housing 105 facing away from the tool receptacle 140 along the axis of rotation 199 of the tool receptacle 140.
[0063] According to another embodiment, the light element 170 can be arranged on an end of the housing 105 facing the tool receptacle 140, as shown in Figure 2 Furthermore, the light element 170 can be arranged on an end of the housing 105 facing away from the tool receptacle 140 or on the upper side 117 as well as on an end of the housing 105 facing the tool receptacle 140.
[0064] The operating unit 160 preferably has at least one light element 165. According to one embodiment, at least one angle value is stored in the operating unit 160, which can be selected as a selectable machining angle (a) Figure 3(Ref. 310, 312, 314, 316). Preferably, machining angles of 30°, 60°, and 90° are stored. However, other or additional machining angles may also be stored. For example, two preset machining angles of 45° and 60° and one freely selectable machining angle may be stored, or three preset machining angles of 30°, 60°, and 90° and one freely selectable machining angle may be stored. Other combinations of preset and freely selectable machining angles may also be considered.
[0065] Furthermore, the operating unit 160 can preferably be coupled to an external device. Preferably, the selectable machining angle ( Figure 3 The parameters 310, 312, 314, and 316 can be selected via an external device. Preferably, the external device is a computer, smartphone, or similar device equipped with an application for selecting and adjusting at least one processing angle.
[0066] As illustrated, the operating unit 160 is positioned on the upper side 112 of the foot region 191 of the housing 105 of the handheld power tool 100, facing the drive units 120 and 180. Alternatively, the operating unit 160 may be positioned on the upper side 117 or on the end side of the housing 105 away from the tool receiving section 140. Furthermore, the operating unit 160 may also be positioned on the side of the housing 105 perpendicular to the axis of rotation 199, on the battery pack 190, or at any other location on the handheld power tool 100.
[0067] Preferably, a work area lighting device is provided. Figure 3 330 in the middle). Preferably, the work area lighting device ( Figure 3 (330) is associated with directional device 175. Here, the work area lighting device ( Figure 3 (330) preferably has at least one light-emitting element 170.
[0068] Preferably, the operating unit 160 has a work area lighting device. Figure 3 (330 in the example). Furthermore, the operation unit 160 has at least one additional display element (…). Figure 3 318) is used to display other functions, especially device temperature, battery status and / or connection status with external devices.
[0069] For example, the handheld power tool 100 is configured as a hole screwdriver and has an optional impact mechanism 150 illustrated. However, the handheld power tool 100 can also be configured as a drill hammer with the optional impact mechanism 150. However, it should be noted that the present invention is not limited to a hole screwdriver, but can generally be applied to various handheld power tools with and without impact mechanisms, which have a directional device 175.
[0070] When orienting the handheld power tool 100 using the orientation device 175, the handheld power tool 100 preferably first uses a reference surface ( Figure 4 420) is arranged on the surface of the workpiece to be processed. Figure 4 On (410) in the middle. Preferably, the bottom side, that is, the side of the battery pack 190 away from the handle 115, forms a reference surface ( Figure 4 (420 in the middle). It should be noted that the reference plane ( Figure 4 420 in the figure can be any preferably flat surface of the handheld machine tool 100, such as the bottom side, top side 117, end side, and / or one side perpendicular to the axis of rotation 199. Furthermore, the handheld machine tool 100 also has multiple reference surfaces ( Figure 4 (420 in the middle).
[0071] Subsequently, the desired machining angle is adjusted via the operation unit 160. Figure 3 (310, 312, 314, 316 in the text). Then, the orientation device 175 is calibrated and initialized. According to one embodiment, during the calibration of the orientation device 175, at least one light-emitting element 165, 170 emits a third light-emitting color ( Figure 7 (720 in the original text). Preferably, at least one light-emitting element 165, 170 flashes with a third light-emitting color during initialization. Then, at least one light-emitting element 165, 170 turns off. Preferably, the third light-emitting color is blue, but it can also be green.
[0072] It should be noted that the described light emission colors are merely exemplary and should not be considered as limitations on the invention. Therefore, the first, second, and / or third light emission colors can also be any other colors. Furthermore, the user of the handheld machine tool 100 can adjust or select the desired light emission color. It should also be noted that the adjustment and initialization of the desired machining angle can be performed simultaneously or sequentially. Furthermore, the adjustment and initialization of the desired machining angle can be performed using correspondingly assigned operating elements. For this purpose, a separate operating element can be provided. Alternatively, adjustment can be performed via a combination of buttons.
[0073] Now we begin orienting the handheld power tool 100. Here, we only need to consider the actual tilt angle of the handheld power tool 100 ( Figure 6 If (a) the threshold value is exceeded, at least one light-emitting element 165, 170 will emit a first emitting color. Figure 8 (820 in the text). As mentioned above, this only applies within the range of the assigned angles.
[0074] If the actual tilt angle of the handheld power tool is 100 ( Figure 6 a) within the pre-given deviation corresponds to the selected machining angle ( Figure 3the calibration of the hand-held power tool 100 is ended. This is visualized by the at least one light-emitting element 165, 170 emitting light in a second light-emitting color (920 in Fig. 9). Figure 2
[0075] According to one variant, the visualization can also take place according to a flickering frequency. Here, for example, the at least one light-emitting element 165, 170 can flicker instead of emitting in different colors with different flickering frequencies. Here, for example, the at least one light-emitting element 165, 170 can only be able to emit light continuously when the set machining angle is reached.
[0076] Furthermore, a combination of different light-emitting colors and / or different flickering frequencies is also possible, for example fast and slow flickering in the color assigned. Thus, for example, the at least one light-emitting element 165, 170 can flicker in a first light-emitting color with one flickering frequency and continuously emit light in a second light-emitting color. Additionally, an acoustic signal can also be emitted.
[0077] Figure 2 A hand-held power tool 100 is shown with an orientation device 175. Figure 1 According to another embodiment, the at least one light-emitting element 170 arranged on the upper side 117 is arranged on an end of the housing 105 facing the tool receptacle 140. Figuratively, the light-emitting element 170 is arranged along the axis of rotation 199 of the tool receptacle 140 between the tool receptacle carriage 140 and the operating element 152 of the percussion mechanism 150.
[0078] Figure 3 An operating unit 160 of the hand-held power tool 100 is shown. Figure 1 and 2 The operating unit 160 has, for example, an operating element 320 for selecting a machining angle.
[0079] Preferably, at least one angle value is stored in the operating unit 160, which can be selected as the selectable machining angle 310, 312, 314, 316. Exemplarily, the display area 322 is assigned the first machining angle 310, the display area 323 is assigned the second machining angle 312, and the display area 324 is assigned the third machining angle 314. Preferably, the first machining angle is 30°, the second machining angle is 60°, and the third machining angle is 90°. However, any other machining angle can also be stored. One of the predefined machining angles 310, 312, 314 can be selected by pressing the operating element 320 or the selected display area of the display areas 322, 323, 324. Here, the correspondingly selected display area 322, 323, 324 is preferably illuminated. Thus, one of the predefined display areas 322, 323, 324 can be selected by manipulating the operating element 320. Upon each manipulation of the operating element 320, the machining angle 310, 312, 314 is changed stepwise, respectively. After the machining angle 310, 312, 314 has been changed stepwise, the machining angle 310, 312, 314 is reset. For example, upon a first manipulation of the operating element 320, the machining angle 310 is set, upon a second manipulation of the operating element 320, the machining angle 310 is changed to the machining angle 312, upon a third manipulation of the operating element 320, the machining angle 312 is changed to the machining angle 314, and upon a fourth manipulation of the operating element 320, the machining angle 314 can be changed to the machining angle 310 or to the machining angle 316, or the set machining angle 310, 312, 314, 316 can be reset. Furthermore, preferably, there is one further display area 325, in which the desired machining angle 316 can be inputted by an external device in the user mode. Here, the display area 325 preferably displays the selected mode and / or the angle value. As described above, the desired machining angle 316 can be selected by manipulating the operating element 320. For example, upon a fifth manipulation of the operating element 320, the machining angle 316 can be changed to the machining angle 310, or the set machining angle 310, 312, 314, 316 can be reset.
[0080] For the case that the operating unit 160 is disabled, first the operating element 320 is manipulated to activate the operating unit 160. Upon re-manipulation of the operating element 320, the machining angle 310 is set as described above. Upon each setting of one of the machining angles 310, 312, 314, 316, the assigned display area 322, 323, 324, 325 can be blinked, for example, in the illumination color. It is also conceivable that at least one of the illumination elements 165, 170 is blinked here. During the blinking of one of the display areas 322, 323, 324, 325 or the illumination elements 165, 170, the calibration of the orientation device 175 is initialized as described above, wherein the orientation device 175 is aligned relative to the reference surface (Figure 4 in the direction of the arrow 420 in Fig. 4, see also Figures 4-6 .
[0081] It can be considered, for example, that the three machining angles 310, 312, 314 are set such that, upon a first actuation of the operating element 320, the machining angle 310 is set, upon a second actuation of the operating element 320, the machining angle 310 is changed to the machining angle 312, upon a third actuation of the operating element 320, the machining angle 312 is changed to the machining angle 314, and upon a fourth actuation of the operating element 320, the machining angles 310, 312, 314 are reset.
[0082] Furthermore, an optional operating element 340 is preferably provided, by means of which further functions can be selected. The operating element 340 is provided with a display element 318. At least one further display element 318 is configured to display a further function. Here, the display element visually displays the further function, for example the device temperature, the battery status and / or the connection status to an external device. Here, one function can be provided with one display symbol, for example. Furthermore, a light-emitting element can be provided, which emits light and / or flashes.
[0083] According to one embodiment, the operating unit 160 is provided with or realized by a work area illumination device 330. Alternatively, the work area illumination device 330 can also be arranged at any other suitable location of the hand-held power tool 100, for example on the end side of the hand-held power tool 100.
[0084] Furthermore, the operating unit 160 is provided with a light-emitting element 165, which is illustrated diagrammatically. The light-emitting element 165 is configured, for example, in the form of a longitudinal side bar along the operating unit 160. Alternatively thereto, the light-emitting element 165 can also be composed of a plurality of light-emitting elements. Here, the light-emitting elements can be arranged next to and / or on top of one another.
[0085] According to a further embodiment, the display elements 322, 323, 324, 325, 318 can also be configured as operating elements, respectively, by means of which the respectively stored machining angle 310, 312, 314, 316 or further function can be selected directly. Furthermore, the machining angle can also be set by means of a key combination. Here, the display areas 322, 323, 324, 325, 318 can be actuated such that, for example, the machining angle 310 is set upon actuation of the display area 322, the machining angle 312 is set upon actuation of the display area 323, the machining angle 314 is set upon actuation of the display area 324, the machining angle 316 is set upon actuation of the display area 325, and a further function is selected upon actuation of the display area 318.

[0094] It should be pointed out that, in Figures 7 to 9 In the illustrated embodiment, the light-emitting element 165 of the operation unit 160 additionally emits light in a corresponding light-emitting color. However, only the work area lighting device 330 can emit light. Furthermore, the light-emitting element 170 can also additionally emit light from the upper side 117. Additionally, the work area lighting device 330 can also flash at different flashing frequencies instead of emitting a light-emitting color. Furthermore, as described above, the work area lighting device can be equipped with a combination of emitting color and flashing frequency.
