Definitions

  • the invention relates to an electrical device as a first or second system component for a system, according to the preamble of claim 1.
  • a vacuum cleaner and an energy storage module of this type are made from DE 10 2012 003 073 A1 and EP 2 628 431 A1
  • the known electrical device is, for example, a battery pack or a power tool, which can be connected or disconnected via a plug-in connection.
  • the battery pack or energy storage module makes it possible to control a vacuum cleaner located remotely from the electrical device, so that it can be switched on or off, for example.
  • an electrical device according to claim 1 and a method according to claim 13 are provided.
  • the electrical device is an energy storage module or a machine tool.
  • the machine tool or vacuum cleaner can be supplied with electrical energy by the energy storage module.
  • By simply connecting or disconnecting the energy storage module to the machine tool the functions intended to establish or terminate the control connection are triggered or executed. It is possible, but not absolutely necessary, for an operator to perform an additional operating action, for example by pressing a button suitable for authorizing or registering the control connection or triggering such authorization or registration, or the like.
  • Simply connecting or removing the energy storage module (the second system component) from the machine tool or the vacuum cleaner (the first system component) triggers the corresponding processes.
  • the electrical device is the controlling component, so to speak, namely the machine tool or the device supplying the machine tool with power, namely the energy storage module
  • the transition from the disconnected state to the operating state immediately results, for example, in the electrical device sending a registration message to the vacuum cleaner to establish the control connection.
  • Separating the system components from one another can also be advantageous in this context, for example if the energy storage module is disconnected from the machine tool. In this case, the energy storage module or the machine tool sends a disconnection message to disconnect the control connection to the receiving component, in this case the vacuum cleaner. It is also advantageous in this context if, for example, the vacuum cleaner's suction unit switches off. This avoids unnecessary operation or continued operation of the vacuum cleaner.
  • the first system component namely the machine tool, advantageously has a suction connection for connecting a suction hose.
  • the first system component is a machine tool, it is designed to control a vacuum cleaner, which in itself does not form part of the system.
  • a system according to the invention advantageously comprises an electrical device and the respective other system component, so that, for example, a combination of a machine tool and an energy storage module is formed.
  • Such a system can be expanded to include the vacuum cleaner controlled via the control connection.
  • the electrical device is advantageously provided with at least one sensor for detecting the operating state and/or the disconnection state of the device interface.
  • the at least one sensor can be a variety of different types of sensors.
  • a distance sensor can be provided to detect the distance between the system components.
  • the distance sensor for example an ultrasonic sensor, a tactile sensor, or the like, can detect this distance.
  • a plug-in movement when connecting the device interfaces or the system components can also be sensed or detected by such a distance sensor.
  • the distance is different from that for a plug-in movement that has not yet been completed.
  • the senor can comprise a motion sensor for detecting a relative movement of the system components to one another. If, for example, the system components are no longer movable relative to one another or only have a predetermined movement play, this is detected by the sensor. In this way, however, a plug-in movement of the device interfaces to one another can also be detected. If, for example, the device interfaces are moved towards one another, in particular during a plug-in movement, the motion sensor can detect such a relative movement.
  • the first and second system components advantageously have such a motion sensor. If the motion sensors detect the same movement pattern, they can, for example, detect the movement of the device interfaces towards one another and thus a fastening of the first and second system components to one another.
  • the relative movement detected by the motion sensor can be, for example, a rotational movement and/or a linear movement.
  • the motion sensor can, for example, be an acceleration sensor.
  • the at least one sensor can also comprise or be formed by an optical sensor for detecting the other system component.
  • the optical sensor can detect the operating state.
  • the at least one sensor comprises an electrical switch, for example a push-button switch, a push-button switch, or the like, that can be actuated by attaching the system components to one another.
  • an electrical switch for example a push-button switch, a push-button switch, or the like.
  • one system component actuates the switch located on the other system component. This can occur, for example, as part of a plug-in movement.
  • a redundant sensor concept is obviously advantageous. If multiple sensors report the same connection status of the device interfaces to each other or of the system components to each other, for example, the operating status or the disconnection status, clear and practically reliable information can be determined from at least two redundant sensor signals.
  • the device interfaces can be conveniently fixed to each other using a fixing device.
  • the fixing device can hold several components include, for example, a latching device, a clamping device, a locking device or the like.
  • a mechanical actuating element for example a push button, a slide switch, or a sliding actuating element or the like, is provided to actuate the fixing device.
  • the fixing device for example a locking device, can be actuated by the actuating element between a fixing position and a release position.
  • the actuating element can be actuated in the direction of the fixing position of the fixing device or the position of the fixing device in which the system components are fixed to one another.
  • At least one sensor for detecting an actuation state of the actuation element is expediently arranged on such a mechanical actuation element, for example, an unlocking button or the like. Actuation of the actuation element in the direction of releasing the securing device is evaluated or determined by the electrical device as a transition from the operating state to the disconnected state. Thus, the sensor is provided for detecting the operating state or disconnected state of the device interfaces. When the operator releases the securing device, i.e., moves it from the locking position to the release position, this is detected by the sensor and simultaneously evaluated as a signal for a transition from the operating state to the disconnected state.
  • the sensor can be, for example, an electrical switch, an optical sensor, a pressure sensor, or the like. Any sensor concept suitable for detecting the actuation state of the actuation element can be used as such a sensor.
  • the device interfaces can be secured to one another using form-fitting contours, such as plug-in projections and plug-in receptacles, recesses and projections, or the like.
  • a plug-in receptacle can be provided on one system component for a plug-in projection on the other system component.
  • one device interface has plug-in form-locking contours for plugging into plug-in mating form-locking contours of the other device interface along a plug-in axis, as well as electrical contacts for contacting electrical mating contacts of the other device interface to electrically connect the system components, which come into electrical contact with one another during plug-in assembly of the plug-in form-locking contours and the plug-in mating form-locking contours.
  • the electrical contacts for example power supply contacts and/or data contacts, come into direct contact with one another during plug-in assembly.
  • the contacts can be, for example, spring contacts, contact tongues, contact surfaces, or the like.
  • the plug-in form-locking contours and the mating plug-in form-locking contours comprise, for example, guide ribs, plug receptacles and plug projections, guide grooves, and/or the like. Combinations are readily possible.
  • the device interface comprises a data interface, in particular a bus interface.
  • the data interface is, for example, a bus interface, in particular an I2C interface.
  • the energy storage module can exchange data with the machine tool or the vacuum cleaner via the data interface. For example, a number of storage cells, a maximum available electrical power, an electrical capacity or a state of charge or the like can be queried via the data interface. Switching signals, in particular for switching off the energy storage device or the machine tool or the vacuum cleaner, can also be conveniently transmitted via the data interface.
  • the data interface can, however, also comprise a parallel data interface, i.e. a plurality of data contacts are provided, each dedicated to a specific piece of information.
  • the electrical device is designed to detect the operating state and/or the disconnection state, i.e. the connection state of the device interfaces to one another, based on data traffic via the data interface. If, for example, the energy storage module of the machine tool or the vacuum cleaner is asked, so to speak, at the start of operation, which electrical characteristics are available so that the subsequent operation of the vacuum cleaner or the machine tool can be optimized, this is a signal for establishing the operating state. This can, for example, be used by the energy storage module serving as a component of the machine tool to establish the control connection.
  • the device according to the invention terminates the control connection and/or sends a shutdown signal for the vacuum cleaner's suction unit or the like.
  • the data traffic may also be data traffic specifically intended to monitor the disconnection status.
  • At least one verification message is used to detect the operating state or the separation state or both.
  • the verification message can be a unidirectionally sent message, for example a verification message sent by the vacuum cleaner or the machine tool, based on which the energy storage module can recognize whether it is connected to the vacuum cleaner or the machine tool.
  • a dedicated communication means for example a special controller, can be provided for sending the verification message.
  • the disconnection state or operating state can be checked by sending and receiving both a verification message and a response to the verification message.
  • the at least one verification message is preferably sent cyclically and/or at predetermined time intervals.
  • the electrical device is configured to perform authentication when establishing the control connection. Authentication includes, for example, sending an identification parameter, an access password, or the like.
  • the communication interface is configured for encrypted communication via the control connection.
  • the encryption can be, for example, Diffi-Hellman encryption.
  • the communication interface can be, for example, a Bluetooth interface, a Wi-Fi interface, or the like. Communication in a confined space, for example, within a range of up to approximately 10 or 20 meters, i.e., the typical length of a suction hose or suction connection, is particularly advantageous.
  • the energy storage module comprises a module housing and an energy storage device accommodated in the module housing, in particular an arrangement with at least one rechargeable electrical storage cell, for providing electrical energy for powering the power tool or the vacuum cleaner, provided with supply contacts.

  • Sensors or detection devices can be installed on the machine tool and/or vacuum cleaner to detect the connection of the suction hose.
  • the control connection is only established when a suction hose is actually connected.
