Description

Technical Field

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

Background Art

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

[0003] The present invention further relates to a vehicle, particularly a bicycle, including the communication unit. Furthermore, the present invention relates to a drive unit for a vehicle, particularly a bicycle, including the communication unit.

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

[0005] An e-bike often has an antenna attached, for example, for transmitting and receiving GPS data. Thereby, the speed or position of the e-bike can be determined. This antenna is usually directly arranged on the frame or drive unit of the e-bike, for example, an electric motor, whereby the antenna can be easily connected to the control mechanism of the e-bike and is protected from external influences, such as rain.

[0006] At the same time, if the physical size of the electrical ground corresponding to the reference plane of the antenna is defined by the geometry of the transmitting and / or receiving mechanism, for example, based on industrial requirements, the antenna output can be limited. That is, the TRP value (a measure of the total radiated power) and / or the TIS value (a measure of the omnidirectional sensitivity) can drop below the required threshold values. [Overview of the project]

[0007] In one embodiment, the present invention provides 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 vehicle, preferably a motor vehicle such as an e-bike, preferably a drive unit and / or frame, comprising a particularly flat and substantially rectangular support having two substantially opposing surfaces on which the transmitting and / or receiving mechanism can be arranged, and at least one first retaining element, the first retaining element being formed for fixing the support in a component, the first retaining element being made of metal, and the first retaining element covering at least 50% of the support, particularly the substantially rectangular surface facing the component when the support is fixed in place. In one embodiment, the present invention provides a motor vehicle in particular comprising a communication unit according to any one of claims 1 to 19.

[0008] In one embodiment, the present invention provides a drive unit for a vehicle, particularly for a motorcycle, which includes a communication unit according to any one of claims 1 to 19. One of the advantages gained by this is that the transmitting and / or receiving mechanisms of the communication unit can be easily, but precisely, and thus reproducibly, fixed in place, particularly in the components of a motorcycle. A further advantage is that, by means of a metal retaining element, the retaining element is capacitively coupled to the transmitting and / or receiving mechanism, thereby extending the reference plane for the transmitting and / or receiving mechanism to the vehicle frame and / or drive unit.

[0009] The communication unit comprises an electromagnetic transmitting and / or receiving mechanism and a positioning device for fixing the transmitting and / or receiving mechanism in place, particularly on one component of a motorcycle. The positioning device includes a support. This support, in particular, being flat and substantially rectangular, should be understood as a means of holding, housing, or similar for the transmitting and / or receiving mechanism. The support can take on various geometric shapes. The support has a height that is small in proportion to its length and width. In this regard, the cross-section of the support in the direction of length and width may be substantially rectangular. Thus, the support may have two substantially rectangular faces (top and bottom) facing each other, as well as four elongated sides. Alternatively, the cross-section of the support may be circular or oval. When the support is fixed in place, i.e., when the support is positioned on one component of a motorcycle, e.g., an e-bike, one of the two faces may face toward the component or in particular toward the motorcycle, and the other face away from the component. 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 the opposite direction will be referred to as the "top side."

[0010] The positioning device further includes at least one first retaining element, which is formed to position a support in one component. In particular, the components of a motorcycle include, among other things, a drive unit and / or a frame. The first retaining element may, among other things, be formed to detachably secure the support to the component, preferably by screw coupling.

[0011] The first retaining element is made of metal and covers at least 50% of the support, particularly the substantially rectangular surface facing the component when the support is fixed in place. In this case, at least 50% of the underside may be wrapped and / or covered by the first retaining element. This means that the first retaining element covers, guards, and / or covers more than half of the surface of the underside of the support.

[0012] The transmitting and / or receiving mechanism may include an antenna, such as a GPS antenna and / or a broadband mobile radio antenna. Further features, advantages, and embodiments of the present invention are described or disclosed below.

[0013] According to one advantageous modification of the present invention, a second retaining element is provided for fixing the support in place, particularly in a motorcycle component. In particular, the support can be positioned in the vehicle component by the second retaining element and fixed in place by the first retaining element. The advantage of this is that the support can be easily and reliably fixed in place in the vehicle component. In particular, displacement of the support that may occur due to vibration during driving is reduced.

[0014] According to a further advantageous variant of the present invention, the second retaining element is formed as a connecting portion, a retaining through-hole, and / or a projection of a support. The advantage of this is that the second retaining element can be easily positioned on a support element, particularly a motorcycle component. In particular, the support can be inserted into the support element, clipped, and / or snap-fitted. The support element may have corresponding openings and / or recesses formed for accommodating the second retaining element. In particular, the connecting portion, the retaining through-hole, and / or the projection of the support can be inserted into the opening of the support element, clipped, and / or snap-fitted. Alternatively or in addition, the support element may have recesses formed for accommodating the second retaining element. The second retaining element can be inserted into the recess of the support element, clipped, and / or snap-fitted.

[0015] According to a further advantageous variant of the present invention, the first retaining element is positioned on the support in a shape-coupled and / or force-coupled manner, and in particular in a detachable manner. The advantage of this is that secure and flexible positioning is enabled, and the first retaining element is positioned on the support in a replaceable or detachable manner, and thus various first retaining elements can be positioned on the support. This allows the support to be coupled, for example, to components or motorcycles of various dimensions.

[0016] According to a further advantageous variant of the present invention, the first retaining element includes a support plate, which is particularly detachably positioned on a support and may be screwed, clipped, or snap-fitted to the support. Alternatively or in addition, the first retaining element has a coupling element, which is detachably scalable in a vehicle component. The coupling element may be screwed to a component, among other things. For this purpose, the coupling element has a through-hole. The coupling element may be formed, for example, as a through-hole. The advantage of such a coupling element is that the first retaining element can be easily detachably scalable in a support and in a vehicle component, particularly in the vehicle's drive unit and / or frame.

[0017] According to a further advantageous variant of the present invention, the first retaining element can be positioned on a motorcycle component in particular by screw coupling, clip coupling, snap-fit ​​coupling, bayonet coupling, and / or hook-and-loop coupling. This allows the first retaining element to be easily fixed in place on the component. It is advantageous that the first retaining element can be coupled to a vehicle component, such as an e-bike component, and in particular detachably, so that the retaining element can be removed from the e-bike for repair and / or maintenance purposes.

[0018] In one embodiment, the first retaining element is formed as a grounding plate or earth plate. For this purpose, it is preferable that the first retaining element is galvanically coupled to the component, particularly to the frame.

[0019] According to a further advantageous variant of the present invention, the first retaining element and the printed circuit board disposed on the support are arranged in a galvanically insulated manner. A transmitting and / or receiving mechanism is arranged on or on the printed circuit board, in particular. In addition, an interface for connecting to an external mechanism of the e-bike may be provided. The galvanically insulated arrangement of the first retaining element and the printed circuit board allows for the isolation of DC currents, in particular. Thus, the first retaining element acts, at least partially, as an insulator or shield for DC current signals. The first retaining element may be galvanically connected to the frame of the e-bike. This allows the first retaining element to extend its reference plane into the vehicle, in particular into the frame of the e-bike.

[0020] According to a further advantageous variant of the present invention, the first retaining element and the printed circuit board disposed on the support are capacitively coupled. The advantage of this is that the reference plane of the printed circuit board for the transmitting and / or receiving mechanism is expanded. In particular, the capacitive coupling can be enabled across the insulating portion between the reference plane of the transmitting and / or receiving mechanism and the first retaining element. The capacitive coupling can be enabled in particular in the case of high-frequency alternating currents, such as GPS, LTE, or similar signals. Thus, the first retaining element acts as an extension for the alternating current signal that is guided through or generated in the reference plane of the printed circuit board. This can, for example, improve the efficiency of the antenna.

[0021] According to a further advantageous variant of the present invention, the first retaining element is spaced less than 5 mm, preferably less than 3.5 mm, and particularly less than 2 mm, from the printed circuit board placed on the support. This allows the printed circuit board to be more effectively coupled to the first retaining element. At the same time, the printed circuit board can be placed in a space-saving manner, particularly on a motorcycle.

[0022] According to a further advantageous variant of the present invention, a fixing element is provided for positioning the first retaining element within a component. The advantage of this is that the support can be easily coupled to a vehicle, in particular to components of the vehicle, such as the vehicle's drive unit and / or frame. Accordingly, the first retaining element may be coupled directly to the component or indirectly to the component using the fixing element. The fixing element is formed to be coupled, in particular, to the drive unit on the one hand and to the frame on the other hand, in particular to be removable. In this case, the fixing element acts as a frame coupling element and may act, for example, as a tolerance correction element. In embodiments in which the first retaining element is coupled to the fixing element, the first retaining element is coupled to at least the drive unit and / or at least to the frame by the fixing element.

[0023] The fixing elements may be formed in particular as fixing plates, fixing angles, or similar objects. It is preferable that the fixing elements are made of metal. It is preferable that the first retaining element is galvanically coupled to the fixing element.

[0024] The fixing elements may be positioned on the component, i.e., the drive unit and / or frame, by screw connections, clip connections, snap-fit ​​connections, bayonet connections, and / or hook-and-loop fastener connections. Furthermore, the first retaining elements may be positioned on the fixing elements by screw connections, clip connections, snap-fit ​​connections, bayonet connections, and / or hook-and-loop fastener connections.

[0025] According to a further advantageous variant of the invention, a support element for fixing the second retaining element in position in the component is arranged. The support element may be manufactured from a synthetic resin, especially from plastic, and / or from rubber. For example, the support element can be fixed in position by press-fitting, especially in a component of a bicycle, especially in a drive unit. Instead or in addition thereto, the support element may also be fixed in position in a fixing element, for example by press-fitting.

[0026] In one form, the support element has an opening and / or a recess for accommodating the second retaining element. The second retaining element may be inserted, especially clipped, and / or snap-fitted into the opening and / or the recess.

[0027] Further important features and advantages of the invention are apparent from the dependent claims, from the drawings, and from the description of the figures thereto. It is self-evident that the features mentioned above and the features to be explained further below can be used not only in the presented combinations but also in other combinations or alone without departing from the scope of the invention.

[0028] Preferred embodiments and forms of implementation of the invention are shown in the drawings and are explained in more detail in the following description, in which the same or similar or same-function parts or elements are provided with the same reference signs.

[Figure 5] This figure shows a schematic cross-sectional view of a position-fixing device based on one embodiment of the present invention. [Figure 6] This figure shows a schematic configuration of a motorcycle based on one embodiment of the present invention. [Modes for carrying out the invention]

[0030] Figure 1a shows a schematic configuration of a drive unit equipped with a position-fixing device based on one embodiment of the present invention. Figure 1a shows a communication unit 100 in the drive unit 6. Further shown is a position fixing device 1 including a support 2, a first retaining element 3, and a second retaining element 4. The support 2 has a substantially rectangular top surface 5 with rounded corners, and the two corners within the area of ​​the second retaining element 4 are substantially completely rounded, forming a semicircle when viewed from above. The first retaining element 3 includes a coupling element 302 and a support plate 303. The first retaining element 3 is fixed in position in the drive unit 6 by a fixing element 30, which is optional and can be replaced with other fixing elements or fixing methods or omitted. In the illustrated embodiment, the fixing element 30 is fixed to the drive unit 6 and the coupling element 302 by screws. The fixing element 30 is implemented as a fixing plate. The fixing element 30 is coupled to the drive unit 6, and in particular by screws. The fixing element 30 is also coupled to a frame 9 (not shown), and in particular by screws. Accordingly, the fixing element 30 is positioned between the drive unit 6 and the frame 9 and is detachably coupled to both the drive unit 6 and the frame 9, particularly by being screwed in. In other words, the drive unit 6 is indirectly coupled to the frame 9 by the fixing element 30, particularly by being screwed in. In this case, the fixing element 30 acts as a frame coupling element and can, for example, act as a tolerance correction element. The coupling element 302 is coupled to the support plate 303, which is positioned on and supports the support 2. In the illustrated embodiment, the coupling element 302 is integrally coupled to the support plate 303 (see Figure 4). The coupling element 302 is positioned on the support plate 303 at an angle. This coupling element 302 allows the communication unit 100 to be reliably and reproducibly fixed to the drive unit 6 in a specified position and / or at a specified angle.

[0031] The connecting element 302 causes the fixed element 30 and the support plate 303, in the form of a frame connecting element, to be separated from each other at an angle of 7. That is, the plane along the support plate 303 and the plane along the fixed element 30 face each other at an angle of 7. This allows the support 2 to be positioned at any, however specified, angle relative to the drive unit 6. In the embodiment based on Figure 1a, the angle is, for example, -40°. However, other angles are also possible.

[0032] The second retaining 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 by the second retaining 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 press-fitting. When the communication unit 100 is installed on the drive unit 6, the support body 2 can be positioned on the support element 40 by the second retaining element 4 and fixed in position by the first retaining element 3, for example by screwing the first retaining element 3 to the fixing element 30.

[0033] Figure 1b shows a schematic configuration of a drive unit equipped with a position-fixing device based on one embodiment of the present invention. Figure 1b shows further possible arrangements of the position fixing device 1. The coupling element 302 of the first retaining element 3 is directly coupled to the frame 9. As in Figure 1a, the support 2 is positioned within the support element 40 by the second retaining element 4. However, unlike in Figure 1a, the coupling element 302 is not positioned on the drive unit 6 by a fixing element, but is directly fixed in the frame 9 of the motorcycle (not shown). The drive unit 6 is also coupled to the frame 9, and is in particular screwed in. In the embodiment based on the shown Figure 1b, the drive unit 6 is directly coupled to the frame 9, and is in particular screwed in, and is not indirectly coupled via a fixing element 30 in the form of a fixing plate, as in the embodiment based on Figure 1a.

[0034] Figure 2a shows a schematic configuration of a drive unit equipped with a position-fixing device based on one embodiment of the present invention. Figure 2a shows further possible arrangements of the communication unit 100 in the drive unit 6 using the position fixing device 1. The support 2 has a second retaining element 4 in the form of a connecting portion 10 for positioning in the support element 40', the connecting portion 10 being inserted into a corresponding opening 11 in the support element 40'. In the embodiment based on Figure 2, the support element 40' is positioned in the fixing element 30, for example, by press-fitting. When installing the communication unit 100 in the drive unit 6, the support 2 is pressed into the opening 11 with the connecting portion 10 and screwed to the fixing element 30 by the first retaining element 3, particularly the coupling element 302, so that the support 2 is fixed in position in the frame 9 or drive unit 6 by the fixing element 30. The fixing element 30 can be fixed in position in the frame 9 by screwing, press-fitting, or shape-joining. The fixing element 30 is further fixed to the drive unit 6, particularly by screwing. The fixing element 30 is implemented as a fixing plate. The fixing element 30 is coupled to the drive unit 6, and in particular, is screwed to it. The fixing element 30 is also coupled to the frame 9, and in particular, is screwed to it. Accordingly, as also shown in the embodiment based on Figure 1a, the fixing element 30 is positioned between the drive unit 6 and the frame 9 and is detachably coupled to both the drive unit 6 and the frame 9, and in particular, is screwed to it. In other words, the drive unit 6 is coupled to the frame 9 by the fixing element 30, and in particular, is screwed to it. In this case, the fixing element 30 acts as a frame coupling element and can act, for example, as a tolerance correction element.

[0035] Figure 2b shows a schematic configuration of a drive unit equipped with a position-fixing device based on one embodiment of the present invention. Figure 2b shows possible configurations of the position-fixing device 1 in an exploded view. The fixing element 30 is detachably coupled to the frame 9, and the fixing element 30 is also detachably coupled to the drive unit 6, particularly by screw fastening. The support element 40' is fixed in position on the fixing element 30. The support element 40' acts as a holder for the support body 2. For this purpose, the support body 2 has a second retaining element 4 in the form of a connecting portion 10. To position the support body 2 on the drive unit 6 or the frame 9, the second retaining element 4 of the support body 2 is inserted into the opening 11 of the support element 40'. The position-fixing device 1 is fixed in position on the fixing element 30 via the first retaining element 3. The position-fixing device 1 is protected from liquids and dirt by the cover 50.

[0036] Figure 3 shows an illustrative schematic exploded view of a support for a position-fixing device based on one embodiment of the present invention. Figure 3 shows an exploded view of the communication unit 100 with a support 2 of the position-fixing device 1. The support 2 includes a lid 12, a battery 13, an antenna support 14, a PCB printed circuit board 15, two shielding elements 16, and a bottom 17. The battery 13 and the PCB printed circuit board 15 are fixed in place within the antenna support 14. The battery 13 supplies energy to electrical components (not shown) on the PCB printed circuit board 15. The PCB printed circuit board 15, together with the electrical components and the antenna (not shown), is part of the transmit and / or receive mechanism 25. Some of the electrical components on the PCB printed circuit board 15 are shielded from electromagnetic radiation by the shielding elements 16 located on the PCB printed circuit board 15. The PCB printed circuit board 15 may be wired to an external mechanism (not shown) via a guide port 18 for current supply and / or data transmission and / or reception.

[0037] The support 2 can be positioned on a support element (not shown) by a second retaining element 4 in the form of a connecting portion 10 located at the bottom 17, and in particular can be inserted into the support element. Examples of support elements 40, 40' are shown in Figures 1 and 2.

[0038] When the support 2 is fixed in place, the lid 12 has an upper surface 5 and the bottom 17 has a lower surface 5'. Due to its modular structure, the antenna support 14, along with the PCB printed circuit board 15, can be removed from the support 2 and replaced with another electronic mechanism.

[0039] Figure 4 shows a schematic representation of a support for a position-fixing device based on one embodiment of the present invention. In Figure 4, the support plate 303 of the first retaining element 3 is fixed in place by screws on the lower surface 5' of the support 2. The support plate 303 is removably coupled to the support 2 by screws, and therefore the first retaining element 3, including the support plate 303 and coupling element 302, can be replaced. This allows the support 2 to be attached to various drive units or, in particular, motorcycles. In particular, the angle between the support 2 and the drive unit or, in particular, motorcycle can be adapted by the appropriately formed first retaining element 3.

[0040] The support plate 303 encloses or covers at least 50% of the lower surface 5' of the support 2, thereby providing an electrical coupling between the reference plane of the antenna in the PCB printed circuit board 15 and the support plate 303.

[0041] Figure 5 shows a schematic cross-sectional view of a position-fixing device based on one embodiment of the present invention. Figure 5 shows a cross-sectional view of the communication unit 100 with a support 2. A battery 13 and a transmit and / or receive mechanism 25, including a PCB printed circuit board 15, are positioned within the support 2. The PCB printed circuit board 15 is shielded by a shielding element 16 in the direction of the drive unit 6. Shielding can be further improved by a support plate 303 that covers at least 50% of the lower surface 5' of the support 2. Since the first retaining 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 reference plane of the PCB printed circuit board 15 is capacitively coupled to the support plate 303. Thus, the drive unit 6 and, in particular, the support plate 303 act as an extended reference plane for the PCB printed circuit board 15, i.e., part of the reference plane of the PCB printed circuit board 15, and in particular part of the reference plane of the antenna (not shown) of the PCB printed circuit board 15.

[0042] The distance 19 between the support plate 303 and the shield element 16 is 2 mm or less. The lower surface 5' faces towards the drive unit 6, and the upper surface 5 points away from the drive unit 6. This allows the antenna on the PCB printed circuit board 15 to transmit and receive data through the upper surface 5 without any metallic objects affecting the transmit and / or receive output. At the same time, the antenna is partially protected from interference from the drive unit 6 from below by the support plate 303.

[0043] The PCB printed circuit board 15 is connected to the drive unit 6 or, in particular, to an external mechanism (not shown) of the motor car via the guide opening 18. The external mechanism may include, for example, a control mechanism and / or an energy supply mechanism.

[0044] Figure 6 shows a schematic representation of a motorcycle based on one embodiment of the present invention. Figure 6 shows a motorcycle 20 comprising a drive unit 6 and a communication unit 100 which includes a position-fixing device 1 for fixing the position of an electromagnetic transmission and / or reception mechanism 25 on the drive unit 6 or frame 9. This position-fixing device 1 includes, for example, a first retaining element 3, a second retaining element 4, and a support 2 in the embodiment of Figure 2. The support 2 is fixed in position on the drive unit 6 or frame 9 by the position-fixing device 1.

[0045] In summary, at least one embodiment of the present invention has at least one of the following features and / or provides at least one of the following advantages. - Reliable positioning of the transmitting and / or receiving mechanisms, especially in motorcycles, such as e-bikes. - High transmit and / or receive output of the transmit and / or receive mechanism - Flexible arrangement of the transmitting and / or receiving mechanism, particularly in motorcycles, such as e-bikes, regarding the angle and position of the transmitting and / or receiving mechanism. Although the present invention has been described based on preferred exemplary embodiments, the present invention is not limited thereto and can be modified in a wide variety of ways.
