Description

[Technical Field]

[0001] The present invention relates to a communication unit for a vehicle. [Background technology]

[0002] The present invention relates to a communication unit comprising an electromagnetic transmitting and / or receiving mechanism and a fixing device for fixing the electromagnetic transmitting and / or receiving mechanism in a component, preferably a drive unit or frame, in particular of a motorcycle, in particular an e-bike, pedelec or the like.

[0003] The invention further relates to a vehicle, in particular a motorcycle, which includes a communication unit. The invention further relates to a drive unit for a vehicle, in particular a motorcycle, including a communication unit.

[0004] Although the present invention is generally applicable to any vehicle, the present invention will be described in relation to a bicycle in the form of an e-bike or pedelec. Although the present invention is generally applicable to any electromagnetic transmitting and / or receiving mechanism, the present invention will be described in relation to an antenna as the transmitting and / or receiving mechanism.

[0005] E-bikes are often equipped with antennas that are used, for example, to transmit and receive GPS data, thereby enabling the speed or position of the e-bike to be determined. Prior art solutions are known in which the antenna is housed in the drive unit of the e-bike for retrofitting purposes, allowing the antenna to be easily connected to the control mechanism of the e-bike and protected from external influences, for example, rain. In this case, the antenna is inserted loosely into the housing of the drive unit.

[0006] On conventional e-bikes, the antenna is typically mounted too close to metal parts that can affect the transmission power, negatively impacting the transmission and reception quality of the antenna, and also points towards the ground, which negatively impacts the transmission power. Summary of the Invention

[0007] In one embodiment, the invention provides a communication unit comprising an electromagnetic transmitting and / or receiving mechanism and a position fixing device for fixing the electromagnetic transmitting and / or receiving mechanism in a component, preferably a drive unit and / or frame, of a vehicle, preferably a motorcycle such as an e-bike, the communication unit comprising a support, in particular a flat, substantially rectangular support having two substantially opposite faces and on which the transmitting and / or receiving mechanism can be arranged, and at least one first holding element, the first holding element being configured for positionally stably fixing the support to the component.

[0008] In one embodiment, the invention provides, in particular, a motorcycle, comprising a communication unit with an electromagnetic transmitting and / or receiving mechanism according to any one of claims 1 to 15 and a position fixing device. In one embodiment, the present invention provides a drive unit for a vehicle, in particular a motorcycle, comprising a communication unit with an electromagnetic transmitting and / or receiving mechanism according to any one of claims 1 to 15 and a position fixing device.

[0009] One advantage obtained thereby is that the transmitting and / or receiving mechanism of the communication unit can be simply but precisely and therefore reproducibly fixed in position and angle, particularly in a single vehicle component. A further advantage is that the position and angle of the transmitting and / or receiving mechanism can be adapted or optimized to be away from interfering vehicle components, thereby improving the transmitting and / or receiving power.

[0010] The communication unit includes an electromagnetic transmitting and / or receiving mechanism and a fixing device for fixing the transmitting and / or receiving mechanism, in particular on a component of a motorcycle. The fixing device includes a support. This particularly flat, substantially rectangular support is to be understood as, in particular, a holding means, housing, or the like for the transmitting and / or receiving mechanism. The support can have various geometric shapes. In particular, the support has a height that is small compared to its length and width. In this regard, the cross section of the support in the length and width direction can be substantially rectangular. Thus, the support can have two substantially rectangular faces (top and bottom) arranged opposite each other and four elongated side faces. Alternatively, the cross section of the support can be circular or oval. In the fixed state, i.e., when the support is arranged on a component of a motorcycle, such as an e-bike, one of the two faces can face the component or, in particular, the motorcycle, and the other face can face away from the component or, in particular, the motorcycle. In the following, the side facing the component or vehicle, especially the e-bike, will be referred to as the "bottom side" and the side facing away will be referred to as the "top side".

[0011] The position-fixing device further includes at least one first retaining element, which is configured for position-stably and removably fixing the support to a component. The drive unit and / or the frame are particularly examples of the motorcycle component. The first retaining element is configured for removably fixing the support to the component, preferably by a screw connection. Within the scope of the present invention, "position-stably" means that the first retaining element can be removably fixed to a component, particularly of the motorcycle, so that the support assumes a stable and precise, and therefore reproducible or precisely repeatable, mounting position with respect to position and / or angle. The position-stable fixation of the support allows, among other things, a secure fixation of the communication unit to the component. In one embodiment, the first retaining element can be removably and position-stably fixed to the component by a screw connection. In contrast, a loose fixation of the communication unit, for example by loosely inserting it into the housing of the drive unit, does not allow for position-stable fixation.

[0012] Further features, advantages, and further embodiments of the present invention are described below or are disclosed thereby. According to one embodiment, the first holding element defines a fixing plane and the support defines a support plane, the support plane having an angle with respect to the fixing plane between -60° and 90°, preferably between -10° and 90°, in particular between 0° and 90°.

[0013] The fixing plane is defined as a plane passing through the part of the first retaining element that is directly arranged on a vehicle component when the first retaining element is fixed in position, in particular as a plane perpendicular to, for example, the screw-in direction of the screws that fix the first retaining element to the vehicle component. The support plane is defined as a plane passing through the contact surface between the support and the first retaining element. The angle between the fixing plane and the support plane is defined as the angle through which the fixing plane must be rotated in the direction of the support to be parallel to the support plane, in this regard, this angle is negative if the surface of the support points towards the ground and positive if the surface of the support points away from the ground. In this regard, the normal mounting position of the support or the communication unit, in particular on the motorcycle component, is taken as the starting point.

[0014] The transmitting and / or receiving mechanism may include an antenna, for example a GPS antenna and / or a broadband mobile radio antenna. According to an advantageous variant of the invention, a second retaining element is provided for fixing the support, in particular on a vehicle component. In particular, the support can be positioned on the vehicle component by means of the second retaining element and fixed immovably by means of the first retaining element. This has the advantage that the support can be fixed in place on the vehicle component in a simple and reliable manner. In particular, displacements of the support that may occur due to vibrations during travel are reduced.

[0015] According to a further advantageous variant of the invention, the second holding element is configured as a link, a holding hole and / or a protrusion of the support body. This has the advantage that the second holding element can be easily arranged on a support element, in particular of a motorcycle component. In particular, the support body can be plugged, clipped and / or snapped onto the support element. For this purpose, the support element can have corresponding openings and / or recesses formed to accommodate the second holding element. In particular, the link, the holding hole and / or the protrusion of the support body can be plugged, clipped and / or snapped into openings in the support element. Alternatively or additionally, the support element can have a recess formed to accommodate the second holding element. In particular, the second holding element can be plugged, clipped and / or snapped into a recess in the support element.

[0016] According to a further advantageous variant of the invention, the first retaining element is arranged on the support body in a form-locking and / or force-locking manner, in particular removably. This has the advantage that a reliable and flexible fixing is made possible, in particular the first retaining element is arranged on the support body in an exchangeable or removably manner, so that different first retaining elements can be arranged on the support body. This allows the support body to be connected to components or motor vehicles of different dimensions.

[0017] According to a further advantageous variant of the invention, the first holding element comprises a support plate, which is particularly removably arranged on the support, and can be particularly screwed, clipped, or snap-fitted to the support. Alternatively or additionally, the first holding element has a connecting element, which can be removably fixed on a vehicle component. The connecting element can be particularly screwed to the component. For this purpose, the connecting element has a through-hole. The connecting element can be formed, for example, as a through-hole. The advantage of such a connecting element is that the first holding element can be easily removably fixed on the support and the vehicle component, particularly the drive unit and / or frame of the vehicle. The support plate and the connecting element can be particularly integrally formed. The connecting element is particularly arranged at an angle on the support plate. The connecting element is particularly arranged at an angle on the support plate, such that the support plane and the fixing plane are arranged at a defined angle relative to each other. The defined angle between the support plane and the fixing plane may in particular be between -60° and 90°, preferably between -10° and 90°, in particular between 0° and 90°. In embodiments in which the first holding element comprises a support plate, the support plane is in particular parallel to the main extension plane of the support plate, in particular lying in the main extension plane of the support plate.

[0018] In one form of the first holding element, the coupling element may be L-shaped, with one leg of the L-shaped coupling element being arranged on the support and one leg being provided for releasably fastening to the component.

[0019] According to a further advantageous variant of the invention, the first holding element can be arranged on a component, in particular of a motorcycle, by means of a screw connection, a clip connection, a snap-fit ​​connection, a bayonet connection and / or a hook-and-loop connection, so that the first holding element can be easily fixed in place on the component. Advantageously, the first holding element can be connected to a component of a vehicle, for example in the form of an e-bike, in particular in a detachable manner, so that the holding element can be removed from the vehicle for repair and / or maintenance purposes.

[0020] According to an advantageous variant of the invention, the angle between the support plane of the support, which faces the vehicle when the support is fixed in position, and the fixing plane of the first holding element is greater than 0°, in particular greater than 10°, and preferably greater than 20°. In this regard, the fixing plane of the first holding element is defined as a plane passing through the coupling elements of the support, in particular those coupled to the drive unit and / or frame of the motorcycle. This fixing plane is therefore parallel to the surface of the drive unit or frame on which the first holding element is arranged. In the case of a curved surface, the fixing plane is parallel to the tangent plane of the surface at the center point of the holding element. By arranging the underside of the support at an angle relative to the drive unit, the support can be oriented better away from interfering vehicle components, which results in a better transmission power for the antenna.

[0021] According to a further advantageous variant of the invention, a fixing element is provided for fixing the first holding element on the component. This has the advantage that the support can be easily connected to a vehicle component, such as the drive unit and / or frame of the vehicle. Accordingly, the first holding element can be connected to the component directly or indirectly using the fixing element. The fixing element is configured to be particularly removably connectable to the drive unit on the one hand and the frame on the other hand. In this case, the fixing element serves as a frame connecting element and can act, for example, as a tolerance compensation element. In an embodiment in which the first holding element is connected to the fixing element, the first holding element is connected to at least the drive unit and / or at least the frame by the fixing element.

[0022] The fixing element may be formed, inter alia, as a fixing plate, a fixing angle, or the like. Preferably, the fixing element is made of metal. The fixing element may be positionable on the component, i.e., the drive unit and / or the frame, by means of a screw connection, a clip connection, a snap-fit ​​connection, a bayonet connection, and / or a hook-and-loop connection. Furthermore, the first holding element may be positionable on the fixing element by means of a screw connection, a clip connection, a snap-fit ​​connection, a bayonet connection, and / or a hook-and-loop connection.

[0023] According to a further advantageous variant of the invention, a support element is provided for fixing the second holding element on the component. The support element can be made of synthetic resin, in particular plastic, and / or rubber. For example, the support element can be fixed in the component, in particular the drive unit, of a motorcycle by press-fitting. Alternatively or additionally, the support element can also be fixed in the fixing element, for example by press-fitting.

[0024] In one form, the support element has an opening and / or recess for receiving the second retaining element, which may be inter alia plugged, clipped, and / or snap-fit ​​into the opening and / or recess.

[0025] Further important features and advantages of the invention are evident from the dependent claims, from the drawings and from the accompanying figure description. It is obvious that the features listed above and further described below can be used not only in the combinations presented respectively, but also in other combinations or alone without departing from the scope of the invention.

[Figure 7] 1 shows in schematic form a motorcycle according to one embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0028] FIG. 1a shows in schematic form a drive unit with a position fixing device according to one embodiment of the present invention. FIG. 1a shows a communication unit 100 in a drive unit 6. Also shown is a fixation device 1, which includes a support 2, a first holding element 3, and a second holding element 4. The support 2 has a substantially rectangular upper surface 5 with rounded corners, and two corners in the area of ​​the second holding element 4 are substantially completely rounded, forming a semicircle in top view. The first holding element 3 includes a connecting element 302 and a support plate 303. The first holding element 3 is fixed in position in the drive unit 6 by a fixing element 30, which is optional and can be replaced by other fixing elements or fixing methods or can be omitted. In the illustrated embodiment, the fixing element 30 is fixed to the drive unit 6 and the connecting element 302 by screwing. The fixing element 30 is embodied as a fixing plate. The fixing element 30 is connected to the drive unit 6, in particular by screwing. The fixing element 30 is also connected to the frame 9 (not shown), in particular by screwing. Accordingly, the fixing element 30 is arranged between the drive unit 6 and the frame 9 and is detachably connected to both the drive unit 6 and the frame 9, in particular by screwing. In other words, the drive unit 6 is indirectly connected to the frame 9 by the fixing element 30, in particular by screwing. In this case, the fixing element 30 serves as a frame connecting element and may, for example, serve as a tolerance compensation element. The connecting element 302 is connected to the support plate 303, which is arranged on the support body 2 and supports the support body 2. In the illustrated embodiment, the connecting element 302 is integrally connected to the support plate 303 (see FIG. 4 ). The connecting element 302 is arranged at an angle on the support plate 303. The connecting element 302 is L-shaped and includes a leg arranged on the support plate 303 and a leg provided for fixing to the drive unit 6, here the fixing element 30. This coupling element 302 allows the communication unit 100 to be securely and reproducibly fixed to the drive unit 6 at a defined position and / or at a defined angle.

[0029] Due to the coupling element 302, the fixing element 30, here in the form of a frame coupling element, and the support plate 303 are spaced apart from each other by an angle 7, i.e. the plane along the support plate 303 and the plane along the fixing element 30 face each other at an angle 7. This allows the support 2, and therefore the communication unit 100, to be arranged at any, but defined, angle relative to the drive unit 6. The angle 7 is approximately -40° in Figure 1. In particular, in normal use with the communication unit 100 in a drive unit 6 of a motorcycle, the support 2 is rotated from the fixing element 30 towards the ground (not shown), so the angle is negative.

[0030] The second holding element 4 is inserted into the support element 40, which may be made of rubber. The support body 2 rests on the support element 40 with the second holding element 4 and is supported by the support element 40. For this purpose, the support element 40 has a protrusion or recess 8. The support element 40 is also fixed to the drive unit 6, for example by a press fit. When installing the communication unit 100 on the drive unit 6, the support body 2 can be positioned on the support element 40 by the second holding element 4 and can be fixed in position by the first holding element 3, for example by screwing the first holding element 3 to the fixing element 30.

[0031] FIG. 1b shows in schematic form a drive unit with a position fixing device according to one embodiment of the present invention. FIG. 1b shows a further possible arrangement of the fixing device 1. The connecting element 302 of the first holding element 3 is directly connected to the frame 9. As in FIG. 1a, the support 2 is positioned in the support element 40 by the second holding element 4. However, in contrast to FIG. 1a, the connecting element 302 is not arranged on the drive unit 6 by the fixing element 30, but is directly fixed in position on the frame 9, in particular of a motorcycle (not shown). The drive unit 6 is also connected to the frame 9, in particular by a screw. In the illustrated embodiment according to FIG. 1b, the drive unit 6 is directly connected to the frame 9, in particular by a screw, and not indirectly connected via the fixing element 30 in the form of a fixing plate, as in the embodiment according to FIG. 1a. Similar to FIG. 1a, in FIG. 1b the frame 9 and the support plate 303 are separated from each other by a defined angle (not shown) by the connecting element 302. That is, the plane along the support plate 303 and the plane along the frame 9 face each other at an angle.

[0032] FIG. 2a shows in schematic form a drive unit with a position fixing device according to one embodiment of the present invention. FIG. 2a shows a further possible arrangement of the communication unit 100 on the drive unit 6 using the fixing device 1. For positioning on the support element 40′, the support body 2 has a second holding element 4 in the form of a link 10, which in the support element 40′ is inserted into a corresponding opening 11. In the embodiment according to FIG. 2, the support element 40′ is arranged on the fixing element 30, for example, by a press fit. When mounting the communication unit 100 on the drive unit 6, the support body 2 has the link 10 pressed into the opening 11 and is screwed to the fixing element 30 by the first holding element 3, in particular the coupling element 302, so that the support body 2 is fixed in position on the frame 9 or the drive unit 6 by the fixing element 30. The fixing element 30 can be screwed, pressed, or form-fitted on the frame 9. The fixing element 30 is further fixed to the drive unit 6, in particular by a screw fastening. The fixing element 30 is embodied as a fixing plate. The fixing element 30 is connected, in particular screwed, to the drive unit 6. The fixing element 30 is also connected, in particular screwed, to the frame 9. Accordingly, as also shown in the embodiment according to Fig. 1a, the fixing element 30 is arranged between the drive unit 6 and the frame 9 and is detachably connected, in particular screwed, to both the drive unit 6 and the frame 9. In other words, the drive unit 6 is connected, in particular screwed, to the frame 9 by the fixing element 30. In this case, the fixing element 30 serves as a frame connecting element and may, for example, serve as a tolerance compensation element.

[0033] In the embodiment according to FIG. 2 , the support plane, i.e., the plane passing through the support plate (not shown) and thus parallel to the support 2, is substantially parallel to the fixing plane, i.e., the plane passing through the coupling element 302. That is, the angle between both planes (not shown) is substantially 0°. If the support 2 is tilted toward the sky (not shown), i.e., toward the frame 9, the angle is positive. On the other hand, if the support 2 is tilted toward the drive unit 6, i.e., toward the ground (not shown), the angle is negative. This "toward the sky" or "toward the ground" is relevant in particular for the normal use of a motorcycle drive unit. To prevent the antenna's transmission and / or reception power from being adversely affected, the angle should not be less than −60°. For example, an angle of −90° means that the upper surface of the support 2 is pointing toward the drive unit 6, in particular toward the ground, and the upper surface of the support 2 is perpendicular to the plane passing through the fixing element 30, and therefore the support 2 is pointing completely toward the ground. Therefore, the transmitting and / or receiving mechanism (not shown) cannot transmit in the direction of, for example, a GPS satellite (not shown), and therefore the transmitting and / or receiving power is insufficient.

[0034] FIG. 2b shows in schematic form a drive unit with a position fixing device according to one embodiment of the present invention. 2b shows a possible arrangement of the fixing device 1 in an exploded view. A fixing element 30 is removably connected to the frame 9, which is also removably connected to the drive unit 6, in particular by screw fastening. A support element 40' is fixed in position on the fixing element 30. The support element 40' serves as a holder for the support body 2, which has for this purpose a second holding element 4 in the form of a link 10. To position the support body 2 on the drive unit 6 or the frame 9, the second holding element 4 of the support body 2 is inserted into an opening 11 in the support element 40'. The fixing device 1 is fixed in position on the fixing element 30 via the first holding element 3. The fixing device 1 is protected from liquids and dirt by a cover 50.

[0035] FIG. 3 shows, in exemplary schematic form, an exploded view of a support of a position fixation device according to one embodiment of the present invention. FIG. 3 shows an exploded view of the communication unit 100 with the support 2 of the fixed positioning device 1. The support 2 includes a lid 12, a battery 13, an antenna support 14, a PCB 15, two shielding elements 16, and a bottom 17. The battery 13 and the PCB 15 are fixed in place within the antenna support 14. The battery 13 supplies energy to electrical components (not shown) on the PCB 15. The PCB 15, together with the electrical components and the antenna (not shown), is part of a transmitting and / or receiving mechanism 25. Some of the electrical components on the PCB 15 are shielded from electromagnetic radiation by a shielding element 16 arranged on the PCB 15. The PCB 15 can be wired to an external mechanism (not shown) via a guide port 18 for current supply and / or data transmission and / or reception.

[0036] The support 2 can be positioned in a support element (not shown), in particular inserted into the support element, by means of a second holding element 4 in the form of a link 10 arranged on the bottom 17. Examples of support elements 40, 40' are shown in Figures 1 and 2.

[0037] When the support 2 is in a fixed position, the lid 12 has an upper surface 5 and the bottom 17 has a lower surface 5'. Due to the modular construction, the antenna support 14 together with the PCB printed circuit board 15 can be removed from the support 2 and replaced with another electronics arrangement.

[0038] FIG. 4 shows in schematic form a support for a position fixation device according to one embodiment of the present invention. On the underside 5' of the support body 2 shown in Figure 4, the support plate 303 of the first holding element 3 is fixed in position by screws. The support plate 303 is removably connected to the support body 2 by means of screws, so that the first holding element 3 including the support plate 303 and the connecting element 302 can be exchanged. This allows the support body 2 to be attached to various drive units or, in particular, motorcycles. In particular, the angle between the support body 2 and the drive unit or, in particular, motorcycle can be adapted by means of an appropriately shaped first holding element 3.

[0039] The support plate 303 encases or covers at least 50% of the lower surface 5' of the support 2, thereby providing electrical coupling between the reference plane of the antenna in the PCB printed circuit board 15 and the support plate 303.

[0040] FIG. 5 shows in schematic form a cross-sectional view of a position fixation device according to one embodiment of the present invention. FIG. 5 shows a cross-section of the communication unit 100 with the support 2. The battery 13 and the transmitting and / or receiving mechanism 25, including the PCB 15, are positioned within the support 2. The PCB 15 is shielded by a shielding element 16 in the direction of the drive unit 6. Shielding is further improved by a support plate 303, which covers at least 50% of the underside 5′ of the support 2. Since the first holding element 3 is made of metal and is directly fixed in position on the drive unit 6, they are galvanically connected. Due to the small distance between the shielding element 16 and the support plate 303, the PCB 15 is capacitively coupled to the support plate 303. The drive unit 6 and, in particular, the support plate 303 therefore act as a reference ground for the PCB 15, i.e., are part of the ground of the PCB 15.

[0041] The gap 19 between the support plate 303 and the shield element 16 is 2 mm or less. The bottom surface 5' faces towards the drive unit 6, and the top surface 5 faces away from the drive unit 6. In this way, the antenna on the PCB printed circuit board 15 can transmit and receive data through the top surface 5 without metal objects affecting the transmission or reception output. At the same time, the antenna is protected by the support plate 303 against interference from the drive unit 6 from below.

[0042] Via the guide opening 18, the PCB printed circuit board 15 is connected to the external mechanism (not shown) of the drive unit 6 or in particular of the motorcycle, which may include, for example, a control mechanism and / or an energy supply mechanism.

[0043] FIG. 6 shows in schematic form a monorail and support according to one embodiment of the present invention. FIG. 6 shows a motorcycle 20 and a communication unit equipped with a support 2. The support 2 is depicted with X-, Y- and Z-axes 21, 21' and 21", respectively, and the orientation of the support 2 can also be expressed based on these axes. The motorcycle 20 is depicted with corresponding x-, y- and z-axes 22, 22' and 22". In this regard, the directions of the X-, Y- and Z-axes 21, 21' and 21" of the support 2 correspond to the directions of the x-, y- and z-axes 22, 22' and 22" of the motorcycle 20, and therefore this orientation of the support 2 corresponds to the orientation of the support 2 in the motorcycle 20.

[0044] To ensure sufficiently good transmission and / or reception output of the antenna, the upper surface 5 of the support 2 faces away from the components of the bicycle as much as possible, especially away from the drive unit 6, and away from the ground, i.e., in the direction of the positive z-axis 22”. That is, the rotation of the support 2 about the X-axis 21 and the Y-axis 21’ may be up to 130°. In this regard, the posture shown in FIG. 6 is defined as 0°, in which the surface 5 is perpendicular to the Z-axis 21”. In FIG. 6, with respect to the fixed plane along the x-axis 22 and the z-axis 22”, the support plane along the X-axis 21 and the Y-axis 21’ in FIG. 6 rotates at an angle between -60° and 220° at most. For example, the support 2 shown in FIG. 6 is rotated 90° with respect to the fixed plane. The support 2 can be arbitrarily rotated about the Z-axis 21” because this does not change the ratio of the upper surface 5 pointing in the direction of the ground.

[0045] FIG. 7 schematically shows a bicycle according to an embodiment of the present invention. FIG. 7 shows a bicycle 20 comprising a drive unit 6 and a communication unit 100 having a positioning device 1 for fixing the electromagnetic transmission and / or reception mechanism 25 in position in the drive unit 6 or the frame 9. This positioning device 1 includes, for example, the first holding element 3, the second holding element 4, and the support 2 in the embodiment of FIG. 2. The support 2 is fixed in position in the drive unit 6 or the frame 9 by the positioning device 1.
