This makes it possible to easily construct processing tools, especially activation circuits. In particular, the charge of the charging storage device can be fully connected for the charging state of at least one, and especially exactly one, battery pack among a plurality of battery packs.

The timing elements have activation and deactivation time constants, or define them. This makes it possible to accurately (particularly over time) determine whether all conditions for the setting of the motor control device from an inactive state to an active state are met or not met.

[0044] In one embodiment of the invention, the charge of the state device in the active state, particularly the charge storage device in the charging state, is generated or released by an electrical state signal, particularly a state signal pulse, configured to trigger the insertion of the motor control device from an inactive state to an active state by switching the motor operating switch from an unoperated to an operated state. In particular, the activation circuit has an electronic state switch, particularly a transistor. The state device in the active state is configured to insert the state switch from an electrically non-conducting state to an electrically conducting state for release.

The triggering device is configured for generating or releasing an electrical trigger signal, particularly a trigger signal pulse, to trigger the insertion of the motor control device from an inactive state to an active state if multiple battery packs are fully connected and the motor operating switch is not actuated, thereby causing the motor operating switch to switch from inactive to actuated, particularly by the state device in the active state and the transition of the motor operating switch from inactive to actuated, particularly by a state signal, and particularly otherwise not. This makes it possible to insert the motor control device from an inactive state to an active state. In particular, this makes it possible to determine or evaluate whether the state device is in an active state or not. In particular, the term "evaluation device" may be used synonymously with the term "triggering device." Additionally or alternatively, the triggering device may be electronic.

[0046] In one embodiment of the invention, the triggering device is an electronic trigger switch, particularly a transistor. The trigger switch is configured to move from an electrically non-conducting state to an electrically conducting state for generating or releasing. This makes it easy to construct processing tools, particularly activation circuits. Specifically, the charge on the control electrode of the transistor, in order to be in the conducting state, can fully connect the charge of the charging storage device in the charging state and / or to at least one, particularly exactly one, of a plurality of battery packs, particularly by means of a motor-operated switch. Further, additionally, or alternatively, the movement can be automatic.

The power supply switch is configured to be switched from an electrically inactive state to an electrically active state for releasing the motor control device to control the supply of power, particularly for controlling the flow of power to the motor control device, if multiple battery packs are fully connected and the motor operating switch is not actuated, and thus the motor operating switch is switched from inactive to actuated, particularly by a trigger signal, and particularly otherwise not. This makes it possible to switch the motor control device from an inactive state to an active state. In particular, switching and / or releasing can be automatic. Additionally or alternatively, the charge of the control electrode of the transistor for the conducting state can be fully connected with the trigger signal and / or at least one, particularly exactly one, of the multiple battery packs. Further additionally or alternatively, the term "transmission" can be used synonymously with the term "flow". Further additionally or alternatively, the trigger device and the power supply switch can then be connected in series. Further additionally or alternatively, the power supply switch and the trigger device can be different. Further, or alternatively, the power supply switch and the status device, especially the status switch, can be different. Further, or alternatively, the power supply switch and the motor operating switch can be different. Further, or alternatively, the power supply switch and the connection switch can be different. Further, or alternatively, the motor control device, especially itself in the active state (especially when placed from the inactive state), is configured such that the power supply switch can be held in the on state (especially when placed from the non-conducting state), especially for holding the power supply switch in the on state, and especially for placing the power supply switch from the on state to the non-conducting state, especially by means of a triggering device.

[0048] In one embodiment of the invention, the power supply switch and the motor operating switch are connected in series. Specifically, the power supply switch, the motor operating switch (especially together with the diode of the activation circuit between them), and the motor control device are connected at a node. This makes it possible to easily construct the processing tool, especially the activation circuit. In particular, the conduction direction of the diode can be from the power supply switch (especially together with the node between them) to the motor operating switch.

[0049] In one improved embodiment of the invention, the processing implement is a tree trimmer, or a hedge trimmer, or hedge shears, or lawn shears, or a lawn trimmer, or a multi-tool, or a high-pole saw, or a saw, or a brush cutter, or a blower, or a leaf blower, or pruning shears, or a cutter, or a sweeping implement, or a sweeping roller, or a sweeping brush, or a lawn mower, or a weed cutter, or a shredder, or a power hoe, or a stone cutter, or a pressure washer, or a cleaning implement, or a suction implement, or a spraying and / or misting implement.

[0067] In other words, especially in Figure 1 As shown in the document: Capacitor 9' is charged only if battery packs 101a and 101b are connected and motor operating switch 5 is not operated. Specifically, if battery pack 101a is connected, transistor 8a' is in the ON state (continuous current is possible). Otherwise, transistor 8a' is in the OFF state and current cannot flow. Additionally or alternatively, if battery pack 101b is connected, transistor 8b' is in the ON state (continuous current is possible). Otherwise, transistor 8b' is in the OFF state and current cannot flow. Further additionally or alternatively, continuous current is possible if motor operating switch 5 is not operated, otherwise it is not. Further additionally or alternatively, due to the arrangement of transistor 8b', capacitor 9' is charged only to the voltage level of battery pack 101a.

[0068] Starting from this point, by manipulating the motor operating switch 5, a status signal pulse ZSI is generated from capacitor 9' to transistor 14' (current represented by the dotted line). This causes transistor 15' to be briefly turned on, and the motor control device 4 is supplied with control power KL. Specifically, by manipulating the motor operating switch 5, the voltage of capacitor 9' is connected to node KN'. The voltage rise charges capacitor KO' via capacitor KO, thus briefly turning transistor 14' on, which in turn turns transistor 15' on.

[0069] Thus, the motor control device 4 is supplied with control power KL, which immediately or immediately afterward controls the transistor 14' (current indicated by the dotted line) via a separate wire, in particular keeping it in the on state to maintain its supply of control power KL.

[0070] In particular, the motor control device 4 controls the supply of power KL through a network component (Netzteil, sometimes also called a power supply component), especially a deep discharge protection device and / or a low-dropout regulator (LDO regulator).

[0071] Additionally or alternatively, control depends on the operation of the motor operating switch 5 by means of the motor operating switch evaluation, especially after the motor operating switch 5 and / or the status device 7 and / or before the status device 7 and / or the trigger device 13 being connected in series.

[0072] In addition, the drive power AL is a minimum of 10 watts (W), a minimum of 100W, a minimum of 1kW (kW), a minimum of 2kW and / or a maximum of 10kW, a maximum of 5kW, and a maximum of 3kW.

[0074] As is clear from the embodiments shown and previously described, the present invention provides an advantageous hand-guided processing apparatus with improved characteristics.

[0075] Furthermore, according to the present invention, at least independently, the invention can be: The hand-guided, particularly handheld, processing tool according to the invention comprises: an electric drive motor for driving the processing tool; at least one (especially exactly one) motor operating switch operable by the user; a motor control device for controlling the supply of electric drive power to the drive motor and, in particular, controlling the starting of the drive motor, which, in the active state of the motor control device, depends on the operation of the motor operating switch; an interface for at least one (especially exactly one) battery pack, which can be detached by the user and electrically connected to at least one (especially exactly one) battery pack, for supplying drive power to the drive motor and electrical control power to the motor control device; and an electrical (especially electronic) activation circuit. The activation circuit is configured to put the motor control device from an inactive state to an active state if (especially initially) at least one battery pack is fully electrically connected and the motor operating switch is not operated, and from there (especially secondly or subsequently) the motor operating switch is switched from being unoperated to being operated, and especially not otherwise. In the inactive state, the motor control device is not supplied with control power by at least one battery pack. In the active state, the motor control device is supplied with control power by at least one battery pack.

[0076] This enables the user to intentionally and especially retrospectively engage the motor control device from an inactive state to an active state, and consequently enables the intentional control and therefore intentional start-up of the electric drive motor. In particular, it makes it possible to avoid unintentional engagement of the motor control device from an inactive state to an active state, and consequently avoids unintentional control and therefore unintentional start-up of the electric drive motor, if (especially initially) at least one battery pack is not fully (especially not) connected and the motor operating switch is operated, and from there (especially secondly or subsequently) at least one battery pack switches from not being fully connected to being fully connected.

[0098] In the case of an interface for connecting exactly one battery pack to exactly one battery pack, a full connection can mean that exactly one battery pack is connected.

[0099] Otherwise, it could mean that the motor operating switch is operated before at least one battery pack is fully connected.

[0100] The motor control device and the activation circuit can be different.

[0101] Motor control devices in an active state (especially when placed from an inactive state) can be configured to easily implement control of the drive motor supply to drive power, or to perform tests before or simultaneously with controlling the drive motor supply to drive power, such as testing at least one fully connected battery pack for a particularly sufficient or minimum voltage value, and to implement control of the drive motor supply to drive power only if the test is passed.

[0102] Processing tools, especially motor control devices, can be configured such that the motor control device can remain in an active state if the motor control device is supplied with power by exactly one battery pack.

[0103] The active state can be referred to as the on state or the awake state.

[0104] The inactive state can be referred to as the off state or the sleep state.

[0105] The processing tool, especially the motor control device, can be configured to switch the motor control device from an active state to an inactive state if the motor operation switch is switched from being operated to being not operated, and especially after a preset duration has elapsed since then, and / or no battery pack is connected. In particular, the duration can be greater than zero, especially a minimum of 1 second and / or a maximum of 10 seconds.

[0106] Furthermore, the awakening of the processing instrument can be achieved by operating a switch on the processing instrument that is particularly different from the motor operating switch, for example, to obtain the particularly corresponding charging status of at least one battery pack that is particularly fully connected. In particular, it is not possible or necessary to put the motor control device from an inactive state to an active state, and therefore, the control and thus start-up of the electric drive motor can be achieved by triggering the operation of another switch.

[0107] At least one battery pack interface, motor operating switch, activation circuit, motor control device, and / or drive motor may be connected in series. Additionally or alternatively, the activation circuit may be connected in series and / or in parallel, particularly with a first portion of the activation circuit preceding the motor operating switch and / or particularly with a second portion of the activation circuit following the motor operating switch.

[0108] In one improved embodiment of the invention, the motor operating switch is a circuit breaker. This makes it possible to easily construct the processing tool, and especially the activation circuit.

[0109] In one improved embodiment of the invention, the activation circuit has an electrical state device. The activation circuit is configured to move the state device from an electrically inactive state to an electrically active state, particularly from an active state to an inactive state, if or only if at least one battery pack is fully connected and the motor operating switch is not actuated, and especially otherwise not. This makes it possible, particularly over time, to continuously determine or maintain that all conditions for moving the motor control device from an inactive state to an active state are met or not met. In particular, the state device can be electronic. Additionally or alternatively, this moving can be automatic and / or by means of a motor operating switch.

[0110] In one embodiment of the invention, the state device is an electrical charging storage device, particularly having a capacitor. The inactive state is the discharged state of the charging storage device. The active state is the charged state of the charging storage device. This makes it easy to construct processing tools, especially activation circuits. In particular, the charge of the charging storage device can be fully connected for the charging state of at least one battery pack.

Alternatively or additionally, the activation circuit is configured such that the inactive placement time constant for the transition from an active state to an inactive state is at most 2 ms, particularly at most 1 ms, and particularly greater than zero. Further, additionally or additionally, the activation circuit is configured such that the activation placement time constant for the transition from an inactive state to an active state is greater than, particularly at least 1.5 times, and particularly at least 2 times greater than, the inactive placement time constant for the transition from an active state to an inactive state. This makes it possible for the user to intentionally place the motor control device from an inactive state to an active state, and particularly avoids unintentional placement of the motor control device from an inactive state to an active state. In particular, the term "duration" can be used synonymously with the term "constant".

[0112] In one embodiment of the invention, the state device has two electrical, particularly electronic, timing elements, especially triggers. The timing elements have activation and deactivation time constants, or define them. This makes it possible to accurately (particularly over time) determine whether all conditions for the setting of the motor control device from an inactive state to an active state are met or not met.

[0113] In one embodiment of the invention, the charge of the state device in the active state, particularly the charge storage device in the charging state, is generated or released by an electrical state signal, particularly a state signal pulse, configured to trigger the insertion of the motor control device from an inactive state to an active state by switching the motor operating switch from an unoperated state to an operated state. In particular, the activation circuit has an electronic state switch, particularly a transistor. The state device in the active state is configured to insert the state switch from an electrically non-conducting state to an electrically conducting state for release. This makes it possible to insert the motor control device from an inactive state to an active state by switching the motor operating switch from an unoperated state to an operated state. In particular, the expression "caused or caused by" can be used synonymously with the term "through". Additionally or alternatively, the generation and / or release can be automatic. Further additionally or alternatively, in the case of generation or release, the charge of the state signal of at least one battery pack can be fully connected, particularly by means of the motor operating switch.

[0114] In one improved embodiment of the invention, and more particularly in one design, the activation circuit has an electrical triggering device. The triggering device is configured for the generation or release of an electrical trigger signal, particularly a trigger signal pulse, to trigger the insertion of a motor control device from an inactive state to an active state if at least one battery pack is fully connected and the motor operating switch is not actuated, thereby causing the motor operating switch to transition from inactive to actuated, particularly by the state device in the active state and the transition of the motor operating switch from inactive to actuated, particularly by a state signal, and particularly otherwise not. This makes it possible to insert the motor control device from an inactive state to an active state. In particular, this makes it possible to determine or evaluate whether the state device is in an active state or not. In particular, the term "evaluation device" may be used synonymously with the term "triggering device." Additionally or alternatively, the triggering device may be electronic. Further additionally or alternatively, the generation, release, and / or triggering may be automatic. Further additionally or alternatively, in the case of generation or release, the charge of the trigger signal may be fully connected to the state signal and / or at least one battery pack. Further, additionally, or alternatively, the motor operating switch and the triggering device may then be connected in series. Further, additionally, or alternatively, the status device, and in particular the status switch and the triggering device may then be connected in series. Further, additionally, or alternatively, the triggering device and the status device, and in particular the status switch, may be different. Further, additionally, or alternatively, the triggering device and the motor operating switch may be different.

[0115] In one embodiment of the invention, the triggering device is an electronic trigger switch, particularly a transistor. The trigger switch is configured to move from an electrically non-conducting state to an electrically conducting state for generating or releasing. This makes it easy to construct processing tools, particularly activation circuits. In particular, the charge on the control electrode of the transistor, for the conducting state, can fully connect the charge of a charging storage device in a charging state and / or to at least one battery pack, particularly by means of a motor-operated switch. Further, or alternatively, the movement can be automatic.

[0116] In one improved embodiment of the invention, and more particularly in one design, the activation circuit has an electronic power supply switch, particularly a transistor. The power supply switch is configured to be switched from an electrically non-conducting state to an electrically conducting state for releasing the motor control device to control the supply of power, particularly for controlling the flow of power to the motor control device, if at least one battery pack is fully connected and the motor operating switch is not actuated, and thus the motor operating switch is switched from non-actuated to actuated, particularly by a trigger signal, and particularly otherwise not. This makes it possible to switch the motor control device from an inactive state to an active state. In particular, switching and / or releasing can be automatic. Additionally or alternatively, the charge of the control electrode of the transistor for the conducting state can be fully connected with the trigger signal and / or at least one battery pack. Further additionally or alternatively, the term "transmission" can be used synonymously with the term "flow". Further additionally or alternatively, the trigger device and the power supply switch can then be connected in series. Further additionally or alternatively, the power supply switch and the trigger device can be different. Further, or alternatively, the power supply switch and the status device, especially the status switch, can be different. Further, or alternatively, the power supply switch and the motor operating switch can be different. Further, or alternatively, the motor control device, especially itself in the active state (especially when placed from the inactive state), is configured such that the power supply switch can be held in the on state (especially when placed from the non-conducting state), especially for holding the power supply switch in the on state, and especially for placing the power supply switch from the on state to the non-conducting state, especially by means of a triggering device.

[0117] In one embodiment of the invention, the power supply switch and the motor operating switch are connected in series. Specifically, the power supply switch, the motor operating switch (especially together with the diode of the activation circuit between them), and the motor control device are connected at a node. This makes it easy to construct the processing tool, especially the activation circuit. In particular, the connection can be continuous or fixed in time. Additionally or alternatively, the term "arrangement" can be used synonymously with the term "connection." Further additionally or alternatively, the conduction direction of the diode can be from the power supply switch (especially together with the node between them) to the motor operating switch.

[0118] In one improved embodiment of the invention, the processing implement is a tree trimmer, or a hedge trimmer, or hedge shears, or lawn shears, or a lawn trimmer, or a multi-tool, or a high-pole saw, or a saw, or a brush cutter, or a blower, or a leaf blower, or pruning shears, or a cutter, or a sweeping implement, or a sweeping roller, or a sweeping brush, or a lawn mower, or a weed cutter, or a shredder, or a power hoe, or a stone cutter, or a pressure washer, or a cleaning implement, or a suction implement, or a spraying and / or misting implement. For such processing implements, it is desirable to avoid the intentional shift of the motor control device from an inactive state to an active state, and especially to avoid the unintentional shift of the motor control device from an inactive state to an active state. In particular, the tree trimmer may be referred to as a small chainsaw.

[0119] The system according to the invention has a processing tool and at least one battery pack.

[0120] Further advantages and aspects of the invention will become apparent from the claims and from the description of the embodiments of the invention subsequently illustrated with reference to the accompanying drawings. Hereinafter: Figure 5 A circuit diagram of a system according to the invention, having a hand-guided machining tool according to the invention, is shown schematically. Figures 6 to 11 A circuit diagram of a corresponding, additional hand-guided machining tool according to the invention is shown schematically. Figure 12 A portion of the circuit diagram of yet another hand-guided machining apparatus according to the invention is schematically shown, and Figure 13 A perspective view of the system is displayed.

[0121] Figures 5 to 13 A system 100 according to the invention is shown, having a hand-guided, particularly handheld, processing tool 1 according to the invention and at least one battery pack 101.

[0122] The processing apparatus 1 includes: an electric drive motor 2 (particularly in a driving manner) for driving the processing apparatus 1; at least one (particularly exactly one) motor operating switch 5 (particularly in an actuated manner) operable by a user; a motor control device 4 (particularly in a controlling manner) for controlling the supply of electric drive power AL to the electric drive motor 2 in the activated state of the motor control device 4, depending on the operation of the motor operating switch 5; at least one (particularly exactly one) battery pack interface 3, which is detachable by a user and electrically connected to at least one (particularly exactly one) battery pack 101, for supplying drive power AL to the electric drive motor 2 and electrical control power KL to the motor control device 4 (particularly in a connected manner); and an electrical, particularly electronic, activation circuit 6. The activation circuit 6 is configured to place the motor control device 4 from an inactive state, or if the motor control device 4 is not supplied with control power KL by at least one battery pack 101, into an active state, or if the motor control device 4 is supplied with control power KL by at least one battery pack 101, if at least one battery pack 101 is fully electrically connected and the motor operating switch 5 is not operated, thereby switching the motor operating switch 5 from being unoperated to being operated (especially by placement).

[0123] Specifically, the motor operating switch 5 is a circuit breaker 5', and in Figure 11 In addition, there is a changeover switch 5".

[0124] Furthermore, the activation circuit 6 has an electrical state device 7. The activation circuit 6 is configured to move the state device 7 from an electrically inactive state to an electrically active state, especially from an active state to an inactive state (especially by way of moving it) if at least one battery pack 101 is fully connected and the motor operating switch 5 is not operated, and especially otherwise not so.

[0125] In detail, the state device 7 is the electrical charging storage device 9, and in particular, it has a capacitor 9'. The inactive state is the discharging state of the charging storage device 9. The active state is the charging state of the charging storage device 9.

[0126] Furthermore, the activation circuit 6 is configured such that the activation placement time constant from the inactive state to the active state is at least 5 ms, and particularly at least 10 ms. Additionally or alternatively, the activation circuit 6 is configured such that the inactive placement time constant from the active state to the inactive state is at most 2 ms, and particularly at most 1 ms. Further additionally or alternatively, the activation circuit 6 is configured such that the activation placement time constant from the inactive state to the active state is greater than, and particularly at least 1.5 times, and particularly at least 2 times, the inactive placement time constant from the active state to the inactive state.

[0127] exist Figure 6and 7 In this process, the activation of the time constant is made possible by a dU / dt limiter or a resistor R (especially in series with the capacitor 9' preceding it). Figure 7 In this process, the inactive insertion time constant is made possible by active discharge or by transistor Q and resistor R' (especially in parallel with capacitor 9').

[0128] In detail, the state device 7 has two electrical, especially electronic, timing elements 10a, 10b, and especially a trigger 11, as shown in... Figure 8 and 9 As shown in the figure. Timing elements 10a and 10b have activation and non-activation time constants.

[0129] Furthermore, the charge of the state device 7 in the active state, especially the charge storage device 9 in the charging state, is converted from unoperated to operated by the motor operation switch 5 through a switching mechanism used for the generation of the electrical state signal ZS, especially the state signal pulse ZSI (as in...). Figure 5 , 6 (as shown in 11) or the resulting release (as in Figures 7 to 10 As shown in the diagram), it is particularly used for triggering the insertion of motor control device 4 from an inactive state to an active state (particularly by generation or release). In particular, the activation circuit 6 has an electronic state switch 12, particularly a transistor 12', as shown in... Figures 7 to 10 As shown in the diagram. The state device 7 in the active state is configured to place the state switch 12 from an electrically non-conducting state to an electrically conducting state for release (especially by placing).

[0130] Furthermore, the activation circuit 6 has an electrical triggering device 13. The triggering device 13 is configured to generate or release an electrical trigger signal AS, in particular a trigger signal pulse ASI, to trigger the motor control device 4 from an inactive state to an active state if at least one battery pack 101a, 101b is fully connected and the motor operating switch 5 is not operated, thereby causing the motor operating switch 5 to switch from being unoperated to being operated, in particular by the state device 7 in the active state and the switch 5 to switch from being unoperated to being operated, in particular by the state signal ZS (in particular by generating or releasing).

[0131] In detail, the triggering device 13 is an electronic trigger switch 14, and more particularly a transistor 14'. The trigger switch 14 is configured to be switched from an electrically non-conducting state to an electrically conducting state for generating or releasing (especially by switching).

[0132] exist Figure 10 In the middle, the transistor is doubly acted on transistor 14' via transistors Q' and EN.

[0133] Furthermore, the activation circuit 6 has an electronic power supply switch 15, particularly a transistor 15'. The power supply switch 15 is configured to be switched from an electrically non-conducting state to an electrically conducting state to release the motor control device 4 to control the supply of power KL, particularly configured to control the flow of power KL to the motor control device 4 if at least one battery pack 101 is fully connected and the motor operating switch 5 is not operated, thereby switching the motor operating switch 5 from being unoperated to being operated, particularly by a trigger signal AS (particularly by a switching method).

[0134] Specifically, the power supply switch 15 and the motor operating switch 5 are connected in series, as shown in... Figure 12 As shown in the diagram. In particular, the power supply switch 15, the motor operation switch 5 (especially together with the diode 16 of the activation circuit 6 therebetween) and the motor control device 4 are connected at node KN.

[0135] exist Figure 13 In this embodiment, the processing appliance 1 is a tree trimmer 1'. In alternative embodiments, the processing appliance may be a hedge trimmer, or hedge shears, or lawn shears, or lawn trimmer, or multi-tool, or high branch saw, or saw, or brush cutter, or blower, or leaf blower, or pruning shears, or cutter, or sweeping appliance, or sweeping roller, or sweeping brush, or lawn mower, or weeder, or shredder, or power hoe, or stone cutter, or pressure washer, or cleaning appliance, or suction appliance, or spraying and / or misting appliance.

[0136] In other words, especially in Figure 11 As shown in the document: The capacitor 9' is charged only if the battery pack 101 is connected and the motor operation switch 5 is not operated.

[0137] Starting from this point, by manipulating the motor operating switch 5, a status signal pulse ZSI is generated from capacitor 9' to transistor 14', thereby briefly putting transistor 15' into a conducting state and supplying control power KL to the motor control device 4. Specifically, by manipulating the motor operating switch 5, the voltage of capacitor 9' is increased to node KN'. This voltage jump charges capacitor KO' via capacitor KO, thus briefly putting transistor 14' into a conducting state, which in turn puts transistor 14' back into a conducting state.

[0138] Thus, the motor control device 4 is supplied with control power KL, which immediately or immediately afterward controls the transistor 14' via a separate line, in particular keeping it in the on state to maintain its supply of control power KL.

[0139] In particular, the motor control device 4 controls the supply of power KL through network components, especially deep discharge protection devices and / or low-dropout regulators (LDO regulators).

[0140] Additionally or alternatively, control depends on the operation of the motor operating switch 5 by means of the motor operating switch evaluation, especially after the motor operating switch 5 and / or the status device 7 and / or before the status device 7 and / or the trigger device 13 being connected in series.

[0141] In addition, the drive power AL is a minimum of 10 watts (W), a minimum of 100W, a minimum of 1kW (kW), a minimum of 2kW and / or a maximum of 10kW, a maximum of 5kW, and a maximum of 3kW.

[0142] Additionally or alternatively, the maximum energy content, particularly the rated energy content, of the battery pack 101 is a minimum of 50 Wh (watt-hours), a minimum of 100 Wh, a minimum of 200 Wh and / or a maximum of 4000 Wh, a maximum of 2000 Wh, a maximum of 1000 Wh, a maximum of 500 Wh, and a maximum of 337 Wh.

[0143] As is clear from the embodiments shown and previously described, the present invention provides an advantageous hand-guided processing apparatus with improved characteristics.

[0144] Furthermore, according to the present invention, it can be, or at least independently, an invention that can be: The hand-guided, especially handheld, processing tool according to the invention comprises: an electric drive motor for driving the processing tool; at least one (especially exactly one) motor operating switch operable by the user; a motor control device for controlling the supply of electric drive power to the electric drive motor and, in particular, controlling the starting of the electric drive motor, which, in the active state of the motor control device, depends on the operation of the motor operating switch; at least one battery pack interface for electrical connection, operable by the user, to supply drive power to the drive motor and electrical control power to the motor control device; and an electrical, especially electronic, activation circuit. The activation circuit is configured to place the motor control device from an inactive state to an active state if (especially initially) at least one battery pack is fully electrically connected and the motor operating switch is not operated, and from there (especially secondly or subsequently) the motor operating switch is switched from being unoperated to being operated, and especially not otherwise. In the inactive state, the motor control device is not supplied with control power by at least one battery pack. In the active state, the motor control device is supplied with control power by at least one battery pack.

This makes it possible to place the motor control device from an inactive state to an active state.

[0185] In one embodiment of the invention, the activation circuit includes an electronic power supply switch, particularly a transistor. The power supply switch is configured to transition from an electrically inactive state to an electrically active state to release the motor control device to control the supply of power, particularly to control the flow of power to the motor control device, if at least one battery pack is fully connected, particularly if the high-voltage side battery pack is connected, and the motor operating switch is not actuated, thereby triggering the motor operating switch to transition from inactive to actuated, particularly by a trigger signal, particularly generated by the high-voltage side battery pack, and particularly otherwise not. This makes it possible to transition the motor control device from an inactive state to an active state. In particular, the transition and / or release can be automatic. Additionally or alternatively, the charge of the control electrode of the transistor for the conduction state can be connected to the trigger signal and / or particularly only one, particularly the high-voltage side battery pack.

[0186] In one embodiment of the invention, the processing apparatus has at least one voltage limiter, particularly a Z-type diode, for limiting the voltage at the gate of the transistor below the transistor's breakdown voltage. This makes it possible for at least one battery pack interface to be configured for connection to at least one battery pack with a high or large rated voltage, particularly above the breakdown voltage. In particular, the voltage limiter may be connected in parallel with respect to the transistor's gate. Additionally or alternatively, the term "control electrode" is used synonymously with the term "gate".

[0187] In one improved embodiment of the invention, at least one battery pack interface is configured for connection to at least one battery pack having a rated or nominal voltage of at least 18V, particularly 24V, particularly 28V, particularly 36V, and particularly maximum 96V, particularly maximum 84V, particularly maximum 72V, particularly maximum 60V, particularly maximum 48V, and particularly maximum 42V.

[0195] In detail, the processing apparatus 1 has at least two, and in particular exactly two, rectifier diodes 7a, 7b. The rectifier diodes 7a, 7b are respectively connected in parallel in the locking direction relative to one of the at least two, and in particular exactly two, series-connected battery pack interfaces 3a, 3b.

[0196] In addition, the motor operating switch 5 is a circuit breaker 5'.

[0197] Furthermore, the activation circuit 6 has an electrical state device 8. The activation circuit 6 is configured to move the state device 8 from an electrically inactive state to an electrically active state if at least (especially exactly) one of the battery packs 101, 101a on the low-voltage side is fully connected and the motor operating switch 5 is not operated, and especially otherwise not so, especially from the active state to the inactive state (especially by way of moving).

[0198] In detail, the state device 8 is an electrical charging storage device 9, specifically having a capacitor 9'. The inactive state is the discharging state of the charging storage device 9. The active state is the charging state of the charging storage device 9.

[0199] Furthermore, the activation circuit 6 is configured such that the activation placement time constant from the inactive state to the active state is at least 5 ms, and particularly at least 10 ms.

[0200] exist Figures 14 to 17 In this embodiment, the inactive insertion time constant is made possible by a resistor R (especially in parallel with capacitor 9'). In an alternative embodiment, the inactive insertion time constant and / or the active insertion time constant can be achieved or made possible without a resistor R, especially based on the natural insulation resistance (especially of capacitor 9').

[0201] Furthermore, the charge of the state device 7 in the active state, especially the charge storage device 9 in the charging state, is converted from unoperated to operated by the motor operation switch 5 through a switching mechanism used for the generation of the electrical state signal ZS, especially the state signal pulse ZSI (as in...). Figures 14 to 17 (as shown in the figure) or the resulting release, especially for the triggering of the motor control device 4 from an inactive state to an active state (especially in a generating manner).

[0202] Furthermore, the activation circuit 6 has an electrical triggering device 10. The triggering device 10 is configured to generate or release an electrical trigger signal AS, in particular a trigger signal pulse ASI, for releasing the motor control device 4 from an inactive state to an active state if at least (in particular, just) one of the battery packs 101, 101a, 101b, especially on the low-voltage side, is fully connected and the motor operating switch 5 is not operated, thereby triggering the motor operating switch 5 to switch from being operated to being operated, especially by the state device 8 in the active state and the switch 5 from being operated to being operated, especially by the state signal ZS (in particular by generating or releasing).

[0203] In detail, the triggering device 10 is an electronic trigger switch 11, especially a transistor 11'. The trigger switch 11 is configured to be switched from an electrically non-conducting state to an electrically conducting state for generating or releasing (especially by switching).

[0204] Furthermore, the activation circuit 6 has an electronic power supply switch 12, particularly a transistor 12'. The power supply switch 12 is configured to switch from an electrically non-conducting state to an electrically conducting state to release the motor control device 4 to control the supply of power KL, particularly configured to control the flow of power KL to the motor control device 4 if at least one battery pack 101, 101a, 101b is fully connected, particularly if the high-voltage side battery pack 101b is connected, and the motor operating switch 5 is not operated, thereby triggering the motor operating switch 5 to switch from being unoperated to being operated, particularly by a trigger signal AS (particularly by switching) generated particularly by the high-voltage side battery pack 101b.

[0205] In detail, the processing apparatus 1 has at least one voltage limiter 13, 14, especially a Z-type diode 13', 14', for limiting the voltage at the gates G11', G12' of transistors 11', 12' to below the breakdown voltage DSP of transistors 11', 12' (especially in a limiting manner).

[0206] In addition, at least one battery pack interface 3, 3a, 3b is configured for connection with at least one battery pack 101, 101a, 101b having a nominal voltage NSP of at least 18V, especially at least 24V, especially at least 28V, especially at least 36V.

[0207] exist Figures 14 to 17 In this embodiment, the processing appliance 1 is a tree trimmer 1'.

[0208] In other words, especially in Figure 14 and 15 As shown in the document: If the two battery packs 101a and 101b are connected or in contact, a voltage Va+Vb exists at the machining fixture 1, and the machining fixture 1 can be turned on via the motor operating switch 5, in particular, starting the electric drive motor 2. If, or when only battery pack 101a is connected or present, a voltage Va exists at the machining fixture 1 via the rectifier diode 7b, which may be sufficient to turn on or operate the machining fixture 1. The same applies when only battery pack 101b is present. Then a voltage Vb exists via the rectifier diode 7a, which may be sufficient to operate the machining fixture 1. In this case, turning on the machining fixture 1 via the motor operating switch 5 should be avoided or prevented. Similarly, it should be prevented that the machining fixture 1 can be turned on when battery pack 101b is not present and Va exists at the machining fixture 1 via the rectifier diode 7b. Furthermore, it should be prevented that the machining fixture 1 is turned on when battery packs 101a and 101b are connected in the case of the operated motor operating switch 5. The processing fixture 1 can only be activated when all battery packs 101a and 101b are present and then the motor operation switch 5 is actuated. This function is achieved through... Figure 14 The activation circuit 6 in the middle is used to achieve this.

[0209] In detail, with battery pack 101a present, capacitor 9' is charged to voltage Va. By operating motor operation switch 5, the charge of capacitor 9' is conducted to the gate G11' of NMOS transistor 11' via resistor R'. Z-diode 13' limits the voltage at gate G11' to an allowable value. Transistor 11' is switched on or off as long as motor operation switch 5 is operated and the charge on capacitor 9' is sufficient. With battery pack 101b present, current flows through resistors R" and R"'. The voltage drop at resistor R" (limited by Z-diode 14') switches PMOS transistor 12 on or off. The total operating voltage (the sum of Va and Vb) is then present at connector VO, specifically to supply control power KL to motor control device 4. Current here is limited by resistor R"".

[0210] In particular, the control of the drive power AL supplied to the electric drive motor 2 is achieved by means of a power switch LS.

[0211] Alternatively or additionally, control depends on the operation evaluated by the motor operating switch 5.

[0212] The activation circuit 6 can also be used in a similar manner to prevent the electric drive motor 2 from starting when the battery pack 101 is connected while the motor operation switch 5 is already operated, in the case of a processing appliance 1 with only one battery pack 101. Corresponding embodiments or variations are available in... Figure 16 and 17 It is displayed or shown in the middle.

[0213] In addition, the drive power AL is a minimum of 10 watts (W), a minimum of 100W, a minimum of 1kW (kW), a minimum of 2kW and / or a maximum of 10kW, a maximum of 5kW, and a maximum of 3kW.
