Definitions

  • the invention relates to a control device by which a mechanical or manual movement in electrical switching signals, which are used for process control of an electrically operated device, is converted according to the preamble of claim 1.
  • Such a device may, for example, the EP 1 903 418 B1 be removed.
  • the evaluation is realized by Hall sensors.
  • the joystick is mounted in a housing rotatable or tiltable in several axes, whereby the magnets move when actuated relative to the built-in Hall sensors Hall sensors. Due to the relative motion between the Hall sensors and the magnets, the sensors detect the magnetic field changing at your location and can thus generate electrical switching signals.
  • the device should be able to be used in environments which have increased requirements for electrical components, e.g. regarding climate, such as heat, cold or humidity, or even pollution.
  • the related evaluation principle according to the invention is inductive. Characterized in that the signal generator are wholly or partly made of an electrically conductive material, that the receiving sensors are formed as coils, the windings are energized and generate an electromagnetic field, that the signal transmitter in the unactuated state of the joystick are each arranged adjacent to one of the receiving sensors and that the signal generator and the receiving sensors interact in the actuated state of the joystick in pairs and non-contact electromagnetically, it is achieved that the space of the device can be kept extremely low and at the same time a reliable and simple switching signal generation by the movements of the joystick of the device. In fact, the distance between the signal transmitters and the receiving sensors can be kept very low, so that the installation space of the entire device is extremely low.
  • a control device can be used in areas that are difficult to access and / or provide only a small amount of space available. Accordingly, can For example, the device according to the invention may be arranged adjacent to a handle of a bicycle in order to operate a navigation device or other electrical devices or to control their function with the aid of the device.
  • a tilting plate or one or more radially oriented webs is provided at the free end of the joystick or fastened with this.
  • the tilt plate acts as a signal generator or act the webs due to their electrical conductivity as a signal generator.
  • the shape of the tilt plate and the webs can be designed such that they have a bend which is perpendicular to one of the tilt axes.
  • the tilt plate or the webs facing away from the receiving sensors of these so that the tilt plate and webs in the receiving sensors in the unactuated state of the control stick are further spaced than in the actuated state of the joystick, since by tilting the joystick of the tilt plate or the respective web is moved in the direction of the receiving sensor.
  • the receiving sensors are a winding and to install or integrate them directly in a printed circuit board, as this ensures that the space height of the circuit board is not increased by the windings and that an electromagnetic field is generated by the electrically conductive windings , As soon as an electrically conductive body, for example in the form of the tilting plate or the web, reaches the region of the electromagnetic field of the coil, eddy currents are created in the tilting plate or in the web, which withdraw energy from the electromagnetic field.
  • the changes in the electromagnetic field can be measured or detected by an evaluation device, so that is achieved by a corresponding predetermined programming that a switching value or threshold is adjustable, which corresponds to a predetermined distance between the receiving sensors and the respective signal generator, which exclusively a switching signal can be generated.
  • each of the receiving sensors is arranged in a separate resonant circuit, because this ensures that the changes in the electromagnetic field of each sensor when approaching the signal generator can be detected by the evaluation device to immediately generate a corresponding switching signal. Consequently, the switching signal generation is a fast and reliable switching function.
  • the joystick Since the joystick is tiltably mounted in a universal joint, which has two tilt axes extending perpendicular to each other, the joystick can be deflected into four different tilt positions. Escaping to each of the deflection position of the joystick while one of the receiving sensors is provided, the electromagnetic field is changed upon penetration of an electrical conductor in the form of the tilting plate or the webs, so that an electrical switching signal is formed.
  • the joystick may be held axially displaceable in the housing alone or together with the universal joint, so that the joystick can also be moved in the direction of the receiving sensor arranged immediately below.
  • the tilting disk there are five different pairs of signal transmitters and receiving sensors, which each generate an independent switching signal. It is readily possible to double the tilt axes of the universal joint, so that a total of four tilt axes are present at an angle of 45 ° to each other. Depending on the size of the housing, the tilting axes can be multiplied as required.
  • the signal transmitter and the receiver sensors are arranged in pairs to one another, so that each pair of signal transmitter and receiver sensor in the respective circuit generates an independent switch signal which can be assigned to a switching function as it approaches.
  • a device 1 in the FIGS. 1 and 2 a device 1 can be seen, are to be converted by the mechanical or manual movements 2, 3 in an electrical switching signal for controlling an electrical device 30.
  • the control device 1 consists of a housing 4, in which a control stick 5 is mounted both axially displaceable in the direction of movement 2 and about two axes A, B in the tilting movement 3.

  • the evaluation device 10 namely constantly monitors the respective circuit 9 and thus recognizes immediately when a frequency change occurs in one of the circuits 9.
  • the signal generator 11 to 15 and the receiving sensors 21 to 25 are connected in pairs. Due to the mechanical design, only one pair 11 and 21, 12 and 22, 13 and 23 or 14 and 24 move towards each other during tilting movements, and thus the corresponding change of the electromagnetic field can be unambiguously assigned to a pair. In the case of axial central actuation, this applies to the pair 15 and 25.
  • control stick 5 is axially displaceable in the direction of the reception sensor 25 arranged in the center, so that one of the electrical switching signals is produced by depressing the control stick 5.
