Definitions

  • the invention relates to a device, in particular an electronic gas system, in particular for motorcycles, having a handle and a measuring arrangement assigned to this handle, wherein a rotary movement of the handle is converted to the measuring arrangement and acts on it, according to the features of the preamble of patent claim 1.
  • EP 1 464 571 A2 discloses an electronic gas system device for motorcycles which is arranged on a handlebar element and which has at least one rotary gas control element which can be rotated on the handlebar element in an actuation direction from an idle position to a full-throttle position, a rotary position sensor, which is arranged outside the axis of rotation of the rotary gas control element, wherein the rotary position sensor consists of a rotor unit and a stator unit, wherein the rotor unit can be moved with the rotary gas control element in relation to the stator unit in a rotatable manner, and wherein the axes of rotation of the rotor unit and the rotary gas control element are arranged parallel at a distance from one another , and wherein the rotor assembly is displaceable by an engagement member connected to the rotary throttle member and having a first number of teeth which mesh with a second number of teeth on a toothed member, the toothed member being integral with the rotor unit is coupled or the rotor unit
  • the invention is based on the object of improving a generic device, in particular with regard to its method of manufacture, its reliable mode of operation and a compact design.
  • the invention departs from this principle.
  • the rotary movement of the handle is converted into a linear movement that influences the measuring arrangement.
  • means are provided for this purpose which convert a rotary movement of the handle into a linear movement of at least one part of the measuring arrangement.
  • the means have a straight rack section of a base of the device and a round rack section that interacts with it and is assigned to the handle.
  • the toothed rack sections which are straight or formed, can be optimally and compactly built and matched to one another.
  • only part of the round toothed rack section is in contact with the straight toothed rack section, and these parts are engaged, so that wear is significantly reduced. This will have an advantageous effect on the durability of the device.
  • this allows a compact design of the entire device, in particular those elements on which Handle are arranged and those elements that are arranged on the base can be achieved
  • a magnet holder which can be moved for this purpose and has at least one magnet, is arranged on the base.
  • Base and magnet holder can be two separate components that are also manufactured separately from each other.
  • the base and the magnet holder form a relevant component.
  • These components are preferably produced in a plastic injection molding process. This can be automated very well, especially for old things, even for large quantities.
  • the magnet holder has the straight toothed rack section. This makes it possible for the magnet holder to be designed on the one hand to accommodate the at least one magnet that acts on a sensor element. On the other hand, the magnet holder also has the straight toothed rack section, with which the rotational movement of the handle is converted into a linear movement of the magnet holder, so that the at least one magnet is moved past the sensor element in a linear movement.
  • the magnet holder is produced in a plastic injection molding process, with the at least one magnet being inserted into the injection mold and being encapsulated with a plastic material.
  • a one-piece element is available that has the straight toothed rack section and also the at least one magnet that acts on the sensor element. First of all, this facilitates assembly of this element on the base of the device.
  • the base has a sensor element that interacts with the at least one magnet.
  • the at least one magnet thus forms the measuring arrangement in conjunction with the sensor element, with the at least one magnet being moved linearly past the sensor element.
  • the base includes a printed circuit board on which at least the sensor element is arranged.
  • the circuit board forms the base or it is integrated into the base. This integration can be achieved, for example, by overmoulding the printed circuit board with the components located thereon, in particular the sensor element. As a result, the components including the sensor element and the circuit board itself are protected from external influences and such a base can be assembled very easily.
  • the handle forms a guide channel for guiding a partial area of the magnet holder. This improves the interaction of the rotationally moving parts of the handle with the linearly moving part of the base and increases the precision of the measuring arrangement.
  • the guide channel of the handle only interacts with a fixed element of the base (without interacting with a linearly moving part on the base, such as the magnet holder), so that the handle can be guided on the base.
  • both the handle on the base and the linear movable part of the base, in particular the magnet holder are guided in a defined manner in their movements as a result of the action on the handle.
  • the handle has a tube and the tube with the round toothed rack section and/or the magnet holder with the straight toothed rack section consist of plastic material.
  • a tube for the handle has the advantage that it can be produced in a plastic injection molding process, with the round toothed rack section being formed at the same time, preferably in an end region of the tube.
  • This tube can be provided with a casing that is, for example, ergonomically shaped or consists of a non-slip material.
  • This at least two-part design of the handle has the advantage that it is optimally tailored to its tasks (on the one hand grip and on the other hand the design of the round toothed rack section). can be.
  • the magnet holder which can also be produced in a plastic injection molding process, in the course of which the holder for the at least one magnet and the straight toothed rack section can be formed. If a holder is designed for the at least one magnet, it can then be used as a separate component in this holder and fixed, for example glued, pressed or latched. As an alternative to this, it is possible to consider inserting the at least one magnet into a mold when the magnet holder is produced in the plastic injection molding process and then overmoulding it. This advantageously eliminates a subsequent assembly process for the at least one magnet.
  • the same poles or the different poles of the two magnets face each other. This allows the output characteristic of the measuring arrangement can be adjusted in a targeted manner or the linear path of the magnet holder can be extended from its one end point to its other end point on the base.
  • the sensor element in particular a Hall element, is always acted upon by an almost homogeneous magnetic field when the magnet holder is moved linearly past the sensor element between its two end points.
  • a two-part magnet system will therefore be installed, since the resulting magnetic field can be evaluated better for a Hall sensor than with a simple bar magnet. This allows a greater signal strength to be achieved over the measuring range, which results in a lower signal deviation and also makes the system more robust against external interference fields.
  • the handle (tube) has a toothed wheel section circumferentially at one end.
  • This gear section acts on a linearly displaceable block (rack) of a measuring arrangement (or a part of the measuring arrangement), in which at least one magnet (specifically two magnets with mutually aligned magnetization directions) is arranged.
  • a corresponding sensor, on which the magnet acts, is arranged on a printed circuit board (PCB) which is located below the sliding block.
  • PCB printed circuit board
  • the measuring arrangement works contact-free, preferably on a magnetic basis, with the linear movement of the at least one magnet acting on a corresponding sensor element, in particular a Hall element, so that an output signal representing the position of the handle can be generated by the sensor element.
  • a device 1 in particular an electronic gas system, in particular for motorcycles, is shown in various views in FIG. 1, this device 1 being explained in more detail below with reference to the other figures.
  • the device 1 is shown in a three-dimensional representation.
  • the device 1 has a handle 2 which is rotatable about its longitudinal axis. The turning movement of the handle 2 is preferably possible between two stops.
  • a base 3 which is stationary, for example on a steering fork of a motorcycle. In February 2 it is shown that the base 3 has a cover 4, underneath which further elements of the device 1 that are still to be described are arranged. In contrast, FIG. 3 shows that the cover 4 has been removed.
  • a cable 5, preferably such a cable leads out of the base 3, with a plug connector 6 being arranged at one end of the cable 5.
  • the plug connector 6 is plugged into an electronic device, in particular an engine control unit.
  • FIG 4 shows further details of the device 1.
  • the handle 2 comprises a tube 7, this tube 7 preferably extending over the entire length of the handle 2 and a little beyond it, this extension being shown in Figure 3 is recognizable.
  • a magnet holder 8 with at least one magnet 9 is assigned to the illustrated end of the tube 7 . While the tube 7 can be rotated about its longitudinal axis by acting on the handle 2, the magnet holder 8 moves for a long time relative to the base 3.
  • the magnet holder 8 is assigned a printed circuit board 10 with electronic elements arranged on it and at least one is not detailed here designated sensor element.
  • the at least one magnet 9 acts on the sensor element, so that the output signal of the sensor element can be processed by the electronic components on the printed circuit board 10 and made available to the electronic device, in particular the engine control unit, via the cable 5 .
  • FIGS. 1 Further individual parts of the device 1 are shown in FIGS.
  • FIG. 5 shows the magnet holder 8, which includes a receptacle 11 for the magnet 9, which has not yet been used here.
  • This magnet 9 is inserted into the receptacle 11 and fixed permanently, for example by pressing, latching, gluing or the like.
  • the magnet holder 8 is produced in a plastic injection molding process and the at least one magnet 9 is integrated into the magnet holder 8 in a permanently fixed position.
  • the magnet holder 8 has a straight toothed rack section 12 .
  • the receptacle 11 is designed in the form of a pocket in such a way that the magnet 9 remains visible from the front and in a small partial area after it has been inserted into the receptacle 11 .
  • FIG. 6 shows one end of the tube 7 which extends under the cover 4 of the base 3.
  • FIG. 7 It is clearly evident that this one end of the tube 7 has a round toothed rack section 13 over the entire circumference or, as in this exemplary embodiment, over part of the circumference.
  • the shape of the teeth of both the straight toothed rack section 12 of the magnet holder 8 and the round toothed rack section 13 in the end area of the tube 7 is coordinated in such a way that a rotary movement of the tube 7 causes a displacement, i.e. a linear movement, of the magnet holder 8 relative to the base 3. This linear movement is detected due to the effect of the magnetic field of the at least one magnet 9 on the sensor element on the printed circuit board 10 and converted into a corresponding output signal.
  • FIGS. 7 to 9 different positions of the magnet holder 8 in relation to the base 3 are shown in cross section through the tube 7, illustrated by way of example using the printed circuit board 10.
  • FIG. 7 shows one end stop of the handle 2 (represented by the tube 7)
  • FIG. 8 shows a neutral position of the handle 2
  • FIG. 9 shows the other end stop of the handle 2. While the neutral position of the handle 2 is shown in FIG. 8 as 0°, one end stop in FIG. 7 is reached with a rotation of -10° and the other end stop in FIG. 9 is reached with a rotation of +65°.
  • These ranges of rotation in degrees are purely exemplary and can vary depending on the application. For example, it is conceivable that, starting from the neutral position, a rotation by the same number of degrees, and thus the same angular segment, is possible in both directions.
  • the number of degrees for the end stops (that is, the angular ranges that are swept over when the handle is rotated) can be larger or smaller than those specified as examples be degrees.
  • a rotational movement of the handle 2 by up to ⁇ 180° or, if appropriate, only in one direction (starting from a neutral position) is also fundamentally conceivable. There does not necessarily have to be a noticeable neutral position between the two end stops.
  • FIG. 7 shows that a sensor element 14, in particular a Hall element, is brought out on circuit board 10 alongside other electronic components.
  • the cable 5 consists of a number of individual electrical conductors, with each electrical conductor being connected to the printed circuit board 10 as intended.
  • the tube 7 has a guide channel 15 on its circumference (shown over a partial area of its circumference).
  • This guide channel 15 works together with a guide element (not shown) on the base 3 in order to ensure a defined rotary movement of the tube 7 about its longitudinal axis when a rotary movement is applied to the handle 2 from the outside (e.g. by the driver of the motorcycle).
  • the guide channel 15 can also interact with a guide element (not shown) of the magnet holder 8 so that the tube 7 together with the magnet holder 8 performs a defined joint movement (rotary movement of the tube 7 and linear movement of the magnet holder 8).
  • spaced-apart magnets 9 are arranged in (or on the outside of) the magnet holder 82 . It goes without saying that only a single magnet 9 or more than 2 magnets 9 can be provided in or on the outside of the magnet holder 8 .
  • the round toothed rack section 13 extends over a partial area of the circumference of the tube 7 by approximately 45°. This extension can depending on the application, it can also be greater or less than 45°. The length of the straight toothed rack section 12 must also be adjusted accordingly.
  • FIG. 10 shows the exemplary embodiment illustrated in FIGS. 7 to 9 in different positions in a side view. It can be seen very clearly here that the guide channel 15 of the tube 7 does not interact with the magnet holder 8 . The means by which it interacts with the base 3 are not shown. The adjacent arrangement of the at least one magnet 9 in relation to the sensor element 14 can be clearly seen, with an air gap being present in between so that the at least one magnet 9 can sweep over the sensor element 14 with its magnetic field during the linear movement of its magnet holder 8 via the circuit board 10 .
  • FIG. 10 It can also be seen in FIG. 10 that (in this shown position of the tube 7 or the handle 2) in the upper half of the tube 7, for example three webs running around the outer circumference of the tube 7 are arranged. There can also be more than three or fewer than three webs. If fewer than three webs are present, they can (but do not have to) be made correspondingly wider, whereas if more than three webs are present, they can (but do not have to) be made correspondingly narrower. These webs reinforce the area of the tube 7 opposite the round toothed rack section 13, so that the tube 7 is sufficiently stable in the end area of the tube 7 in which the webs and the lower toothed rack section 13 are arranged (and possibly also next to it). there is also an even distribution of forces during the rotary movement of the handle 2 .
  • the width of the straight toothed rack section 12 preferably corresponds to the width of the round toothed rack section 13. Different widths are also conceivable, depending on the installation space.
  • FIGS. 7 to 9 Analogous to the different positions shown in FIGS. 7 to 9, the respective positions between the at least one (single) magnet 9 and the sensor element 14 are shown once again in FIGS. The same applies to FIG. 14, which once again reproduces the side view corresponding to FIG.
  • FIGS. 15 and 16 show an exemplary embodiment with two magnets 9 which are arranged in (or alternatively from the outside of) the magnet holder 8 .
  • the magnet holder 8 is preferably made of plastics and is produced in a plastic injection molding process, with this process the two magnets 8 being arranged inside the magnet holder 8 and thus being protected, with the straight toothed rack section 12 also being produced at the same time using this process.
  • Figure 15 again shows the circuit board 10 with the sensor element 14 arranged on it, with an air gap being provided between the sensor element 14 and the magnet holder 8 and the magnet holder 8 as a result of the rotary movement of the handle 2, when viewing Figure 15 from right to left and vice versa.
  • the magnetic field of the two magnets 9 is applied to the sensor element 14, so that a corresponding output signal is generated depending on the respective position of the handle 2 is supplied to the electronic device for evaluation or for controlling a corresponding factor.
  • FIG. 16 shows the magnetic field of the two magnets 9 which acts on the sensor element 14 .
  • the presence of the two magnets 9 in the area of the magnetic field that acts on the sensor element 14 when it is swept creates an almost homogeneous magnetic field and can therefore be evaluated.
  • This has the advantage that no error correction of the output signal of the sensor element 14 has to be carried out in the downstream electronic device. This enables very sensitive control, for example of the drive of the motorcycle, by rotating the handle 2 .
  • FIGS. 15 and 16 show that the different poles of the two magnets face each other.
  • the magnet 9 on the left has a north pole N and a south pole S, with the north pole N pointing upwards when the two FIGS. 15 and 16 are viewed.
  • the right-hand magnet 9 has a south pole S pointing upwards and a north pole N pointing downwards (when looking at FIGS. 15 and 16).
  • the different poles of the two magnets 9 face each other.
  • the output characteristic of the measuring arrangement can be adjusted in a targeted manner or the linear path of the magnet holder can be lengthened from its one end point to its other end point on the base.
  • the sensor element in particular a Hall element
  • the sensor element is always acted upon by an almost homogeneous magnetic field when the magnet holder is moved linearly past the sensor element between its two end points.
  • a two-part magnet system will therefore be installed, since the resulting magnetic field can be evaluated better for a Hall sensor than for one simple bar magnet. This allows a greater signal strength to be achieved over the measuring range, which results in a lower signal deviation and also makes the system more robust against external interference fields.
