Definitions

  • the present invention relates to a switching device for the controlled switching of an electrical connection. Furthermore, the present invention relates to a corresponding method.
  • the present invention is described below mainly in connection with electrical connections in vehicles. However, it goes without saying that the present invention can be used in any application in which electrical connections must be securely closed and disconnected.
  • the electric motors in such vehicles can be operated with voltages of up to 800 V or more. Accordingly, batteries are installed as energy stores in such vehicles, which have high nominal voltages of up to 800 V and more.
  • contactors In order to be able to safely switch the currents in the vehicle on and off, for example in the event of a fault, so-called contactors are usually used. These contactors can use a spring-loaded armature with a contact bridge, which is pressed by an electromagnet against the spring force onto corresponding connection terminals and thereby electrically connects them to one another.
  • the electrical contact In the de-energized state of the electromagnet, the electrical contact is kept open by the spring preload of the armature.
  • the cumulative mass inertia of the armature and the contact bridge can be sufficient to overcome the spring force and close the contact.
  • the contactors for the positive voltage branch and the negative voltage branch are usually installed with different axis directions, so that both contactors do not close at the same time. This type of assembly leads to an increased assembly effort.
  • the WO 2005/059939 A1 discloses an electromagnetic switching device.
  • the DE 196 25 657 A1 discloses an electric lifting armature magnet.
  • the WO 2012 / 033 262 A1 discloses an electrical power switching device.
  • the EP 2 960 923 A1 discloses a switching arrangement.
  • a switching device according to the invention for the controlled switching of an electrical connection is described in claim 1.
  • the high-voltage contactors can close unintentionally under the right conditions, which leads to increased effort during assembly and production.
  • the present invention is based on the finding that the installation of high-voltage contactors in electric vehicles could be simplified if the high-voltage contactors were better protected against the effects of acceleration or vibration.
  • the present invention therefore provides the switching device which is protected against accidental closing due to acceleration or vibration.
  • a positive power connection and a negative power connection can be electrically connected to one another or electrically separated from one another in a controlled manner via a connecting element.
  • the connecting element can thus be switched between a first state and a second state.
  • the connecting element couples the positive power connection to the negative power connection.
  • the positive power terminal is electrically disconnected from, or not connected to, the negative power terminal.
  • the connecting element can have an armature, for example, which is prestressed by a spring, so that it assumes the position of the second state without further activation.
  • the connecting element can also have a magnetic coil, for example, which generates a magnetic field when actuated appropriately and moves the armature into the position of the first state. Consequently, if the coil is de-energized, the spring-loaded armature automatically moves back to the second state position.
  • the switching device provides the blocking element which, in a non-activated state, blocks the connecting element in the second state. In an actuated state, on the other hand, the blocking element releases the connecting element.
  • the non-actuated state of the blocking element denotes a state in which the blocking element is not actuated. For example, there is no active control signal for the blocking element. In the activated state, on the other hand, the blocking element is activated. So there is a control signal at the blocking element.
  • the control signal can be in the form of a control voltage or a control current, for example.
  • a control signal can also be present in the non-driven state, for example, but which characterizes the non-driven state.
  • a control signal can, for example, be a digital control signal which, by way of example only, can identify the non-driven state by a logical "0" and the driven state by a logical "1".
  • control inputs can be provided for the connecting element and the blocking element, even if they are not explicitly mentioned here. These control inputs can be controlled by external units, such as control units in vehicles, in order to control the blocking element and switch the connection element between the first state and the second state.
  • the connecting element By blocking or locking the connecting element, the connecting element cannot move out of the second state even in the case of strong accelerations or vibrations. The electrical connection between the positive power terminal and the negative power terminal is thus safely blocked.
  • the switching device or several switching devices When installing or assembling the switching device or several switching devices, e.g. in a positive voltage branch and a negative voltage branch, it is therefore not necessary to pay attention to the installation direction of the switching devices. Consequently, the switching devices can be installed side by side in the same direction. This enables very efficient and fast assembly, which can also be automated with the help of robots, for example.
  • the blocking element for blocking the connecting element can engage in the connecting element in a form-fitting manner and block it.
  • a form-fitting connection means that the locking element or a component or element of the locking element engages in a form-fitting manner in the connecting element or a component or element of the connecting element.
  • the positive connection cannot be released by excessive forces. The locking of the connecting element is therefore permanently ensured.
  • the form-fitting connection can be produced, for example, by a pawl, a locking lug, a pin or the like, which engages in a corresponding recess or undercut of the connecting element.
  • a non-positive connection can be established, for example, with a type of clutch, such as a slipping clutch.
  • the blocking element can have a movably mounted blocking element, which can be moved into the path of travel of the connecting element and/or out of the path of travel of the connecting element in a controlled manner.
  • the blocking element can be designed, for example, as a pawl, a detent, a pin, a piston or the like.
  • the blocking element can be moved into or out of the path of travel of the connecting element by an actuator, e.g.
  • the blocking element can be moved into the travel path of the connecting element, ie into a corresponding recess or undercut. The connecting element is thus blocked in the second state.
  • the blocking element In order to release the connecting element, the blocking element can be moved out of the travel path, ie the recess or undercut.
  • the Connection element is thus no longer blocked and can change to the first state. It goes without saying that a further actuator can be provided for the connecting element.
  • the blocking element can be mounted in a spring-loaded manner and can be prestressed with a prestressing force in the direction of the travel path of the connecting element.
  • traveling of the connecting element is to be understood as the travel of that element which is movably mounted and changes its position when changing from the first state to the second state or back, in order to establish the electrical contact between the positive power connection and the negative power connection Establish or interrupt the power connection.
  • the biasing force moves the blocking element to the non-energized state position.
  • the blocking element blocks the connecting element. Consequently, no active control is necessary to prevent the electrical connection between the positive power connection and the negative power connection.
  • the direction of movement of the blocking element can, for example, be orthogonal to the travel path of the connecting element or the corresponding component of the connecting element.
  • the blocking element can have an actuator which can be designed to move the blocking element out of the travel path of the connecting element in an actuated state.
  • the actuator can be any type of electrically controllable actuator which can move the blocking element.
  • Such an actuator can be a coil, for example.
  • Other possible forms for actuators are, for example, electric motors such as servos or the like.
  • elements made of bimetal can be used, which heat up and deform when energized.
  • the actuator can be a reversible actuator.
  • a reversible actuator is to be understood as meaning that the actuator does not actively brake or block the blocking element in the de-energized or non-actuated state.
  • a blocking element prestressed by a spring force can consequently be pressed or moved into its rest position by the spring force when the actuator is not activated.
  • the blocking element can be designed in such a way that, in the non-activated state, it enables the connecting element to change from the first state to the second state.
  • the first state of the connection element characterizes the state of the switching element in which the positive power connection and the negative power connection are electrically coupled to one another.
  • the second state characterizes the state of the switching element in which the positive power connection and the negative power connection are not electrically coupled to one another, ie no current flow is possible.
  • the blocking element or the blocking element can positively engage in the connecting element in the non-activated state. A movement of the connecting element into the first state is consequently prevented.
  • the electrical connection between the positive power connection and the negative power connection should be safely separated if, for example, the activation of the switching device fails.
  • the blocking element or the blocking element it may be necessary to move this out of the path of travel of the connecting element.
  • Blockade element are performed such that the movement of the connecting element remains possible in the second state, so even in the non-driven state of the blocking element.
  • corresponding active surfaces e.g. surfaces that are inclined relative to one another (e.g. inclined to the direction of movement of the connecting element), on the connecting element and/or on the blocking element.
  • the connecting element and the blocking element can slide along one another on such effective surfaces.
  • the connecting element can move the blocking element against the spring force, which prestresses the blocking element. If the connecting element is then in the second state, the blocking element or the blocking element can slide back into the non-actuated state.
  • the connecting element has a spring-loaded armature which has a contact bridge for connecting the positive power connection and the negative power connection at a first end and which has an undercut, in particular a mushroom head, at a second end.
  • the spring force is configured to pull the armature into the second state in which the positive power terminal and the negative power terminal are electrically isolated from each other.
  • the blocking element has a spring-loaded pawl, which is pretensioned by the spring force in the direction of the mushroom head and positively contacts and blocks the mushroom head in the non-actuated state of the blocking element and the second state of the connecting element.
  • the blocking element has an electromagnet or a magnetic coil, which can be designed to pull the pawl out of the path of travel of the mushroom head in the activated state.
  • the connecting element can be designed similar to an armature, for example, as used in conventional high-voltage relays. However, such anchors have no way of fixing them.
  • the armature of the switching device according to the present invention can be provided with an undercut.
  • an undercut for example, in the form of a Mushroom head is used for the form-fitting fixation of the anchor by the blocking element. If the blocking element engages in the undercut, it reliably prevents the anchor from moving.
  • An electrical actuator e.g. an electromagnet or a magnetic coil, can be provided for both the connecting element and the blocking element.
  • the armature can be moved into the first position via such an electromagnet when the electromagnet is activated.
  • the spring force automatically moves it to the second position when the electromagnet is not actuated.
  • the pawl is moved out of the traversing path of the armature when the corresponding electromagnet is actuated and is moved into the traversing path of the armature by the spring force when it is not actuated, in order to prevent its movement into the first state.
  • the mushroom head can be designed in such a way that a tip of the mushroom head moves past the pawl when the armature moves from the first state to the second state and an outer surface of the mushroom head that is inclined relative to the direction of movement pushes the pawl back when the pawl is in the non-driven state.
  • one end of the anchor is designed as a mushroom head, it tapers from the undercut towards the end.
  • the conical outer surface of the mushroom head consequently forms an inclined surface to the direction of movement of the armature. Consequently, when moving from the first position to the second position, this inclined surface can slide along the pawl and push it back. If the outer circumference of the mushroom head passes the pawl, it can move back into the non-actuated position and positively blocks the armature.
  • This configuration of the armature with a mushroom head consequently enables the armature to be moved into the second position even when the pawl is not actuated.
  • the switching device can have a state sensor, which can be designed to detect the state of the connecting element and/or the blocking element and to output a corresponding sensor signal.
  • the state sensor can be embodied as a mechanical sensor, e.g., a switch-based sensor, or as a non-contact sensor, e.g., a Hall sensor or the like.
  • the position of the blocking element can be detected and the connection element can be actuated or an error detected accordingly. Additionally or alternatively, the position of the connecting element can also be detected.
  • the information about the states of the blocking element and/or the connecting element can be transmitted, for example, to a control unit which generates the control signals for the blocking element and the connecting element.
  • the switching device can have control electronics, which can be designed to control the connecting element and/or the blocking element based on corresponding input signals.
  • the control electronics can have a passive circuit, which has, for example, capacitors, diodes, inductors and the like. Control signals to the actuator of the blocking element or the actuator of the connecting element can be forwarded to the respective actuator via the control electronics. Consequently, such a circuit can be used to suppress overvoltages and other interference, for example, and clean control signals can be forwarded to the actuator of the blocking element or the actuator of the connecting element.
  • Voltage signals for example, can be used as input signals for the control electronics, that is to say a signal with a predetermined voltage value for controlling the respective actuator.
  • a separate input signal can be provided for each of the actuators.
  • the signals from the status sensor can be output directly by the latter.
  • the control electronics can have signal processing for the sensor signals and output them.
  • control electronics can have a single signal input via which a single control signal for closing the electrical connection between the positive power connection and the negative power connection is provided.
  • control electronics can generate two signals from the individual control signal, one of which in each case controls the actuator of the blocking element or the actuator of the connecting element.
  • control electronics in this embodiment can have a delay element which delays the signal for the actuator of the connecting element compared to the signal for the actuator of the blocking element. This ensures that the connecting element is released before its actuator is activated.
  • a capacitor circuit for example, can be provided as a delay element, which delays the voltage rise of the signal for the actuator of the connecting element. It goes without saying that a digital circuit can also be provided as an alternative.
  • control electronics can have a digital control unit, e.g. a controller.
  • a digital control unit can, for example, control the actuator of the blocking element or the actuator of the connecting element and evaluate the signals of the status sensor for this purpose.
  • Analog control signals, as described above, or digital control signals can serve as the input signal for the control electronics.
  • Digital control signals can be serial or parallel digital signals, for example.
  • the control electronics can have a bus interface via which digital signals can be exchanged.
  • a bus interface can be designed, for example, as a CAN interface, a LIN interface, a FlexRay interface, a network interface or the like.
  • the digital control unit can consequently receive control signals and, based on the sensor signals, control the actuator of the blocking element or the actuator of the connecting element. Furthermore, the digital control unit can output corresponding status information via the digital interface, which can be evaluated by a control unit in a vehicle, for example.

  • the connector 103 is shown in a second state in which it does not couple the positive power terminal 101 and the negative power terminal 102 together. If the connecting element 103 is placed or moved into a first state (indicated by an arrow), the two stamps of the connecting element 103 each lie on the positive power connection 101 and the negative power connection 102 and establish an electrical connection between them.
  • the connecting element 103 has a recess 105 at the end opposite the power connections 101 , 102 .
  • one end of locking element 104 lies in recess 105 and blocks movement of connecting element 103.
  • the blocking element 104 In order to establish the electrical connection between the positive power connection 101 and the negative power connection 102, the blocking element 104 must consequently be removed from the travel path of the connecting element 103 (indicated by an arrow). Although in figure 1 not shown explicitly, it goes without saying that an actuator can be provided for the blocking element 104, which can be controlled in order to remove or withdraw the blocking element 104 from the travel path of the connecting element 103.
  • the connecting element 103 can be brought into the first position by a further (not explicitly shown) actuator, so that the power terminals 101, 102 are electrically coupled to one another.

  • the armature 216 has a mushroom head 217 at its end. In figure 2 it can be seen that an edge of the pawl 210 protrudes into an undercut of the mushroom head 217 . A movement of the armature 216 downwards, ie into the image plane, is consequently prevented by the pawl 210 in a form-fitting manner.
  • a magnetic coil 214 is also arranged in the switching device 200 in such a way that, when energized, it pulls the pawl 210 out of the travel path or the undercut of the mushroom head 217 and thus releases the mushroom head 217 .
