Description

Sattelstütze für ein Fahrzeug und Fahrzeug Seat post for a vehicle and vehicle
Die vorliegende Erfindung betrifft eine Satelstütze für ein Fahrzeug und ein Fahrzeug. The present invention relates to a seat post for a vehicle and a vehicle.
Die im Radbereich mittlerweile etablierten versenkbaren Teleskop-Sattelstützen nutzen teilweise eine elektrische Aktuierung für den Verriegelungs- bzw. Blockademechanismus, um eine kabellose Bedienung zu ermöglichen. Für diese elektrische Aktuierung wird ein elektrischer Energiespeicher, z. B. in Form einer Batterie oder eines Akkumulators, benötigt, um die Funktion zu ermöglichen. Der Einsatz eines elektrischen Energiespeichers bedingt eine begrenzte Betriebszeit. Durch regelmäßiges Wechseln bzw. Laden des Energiespeichers muss der Betrieb abgesichert werden. Störend ist eine gegebenenfalls fehlende Verfügbarkeit aufgrund eines entladenen Energiespeichers. Dazu kommt die Notwendigkeit, den Energiespeicher von außen zugänglich und austauschbar anzuordnen. Some of the retractable telescopic seat posts that have now become established in the cycling sector use electrical actuation for the locking or blocking mechanism to enable wireless operation. For this electrical actuation, an electrical energy store, e.g. B. in the form of a battery or an accumulator, required to enable the function. The use of an electrical energy store requires a limited operating time. Operation must be safeguarded by regularly changing or charging the energy storage device. A possible lack of availability due to a discharged energy store is disruptive. In addition, there is the need to arrange the energy store so that it is accessible from the outside and can be exchanged.
Aus DE 10 2016 208 563 A1 ist eine Längenverstelleinheit zur Änderung der Länge eines Teleskopabschnittes, welcher ein Innenrohr und eine Außenrohr umfasst, bekannt. Die Längenverstelleinheit eignet sich zur Einstellung der Länge von teleskopischen Abschnitten an einem Fahrradgestell, beispielsweise um eine Sattelstütze in der Höhe zu verstellen oder um den wirksamen Federweg an einer Vorderradgabel zu verändern. DE 10 2016 208 563 A1 discloses a length adjustment unit for changing the length of a telescopic section, which comprises an inner tube and an outer tube. The length adjustment unit is suitable for adjusting the length of telescopic sections on a bicycle frame, for example to adjust the height of a seat post or to change the effective spring travel on a front wheel fork.
Aus EP 23 716 99 A1 ist eine Vorrichtung zur Unterbringung eines Speichers für elektrische Energie in der Sattelstütze eines Fahrrads bekannt. EP 23 716 99 A1 discloses a device for accommodating a store for electrical energy in the seat post of a bicycle.
Der vorliegenden Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zu Grunde, eine verbesserte elektrisch aktuierbare Sattelstütze vorzuschlagen. Proceeding from the prior art, the present invention is based on the object of proposing an improved electrically actuable seat post.
Die vorliegende Erfindung schlägt ausgehend von der vorgenannten Aufgabe eine Sattelstütze für ein Fahrzeug mit den Merkmalen nach Anspruch 1 , und ein Fahrzeug mit den Merkmalen nach Anspruch 6 vor. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen gehen aus den Unteransprüchen hervor. Eine Sattelstütze für ein Fahrzeug weist ein Außenrohr, in welchem ein Innenrohr entlang einer Verschiebeachse verschieblich gelagert ist, auf. Die Sattelstütze weist eine Spule, welche innerhalb der Außenrohrs angeordnet ist, auf. Die Sattelstütze weist mehrere Permanentmagnete, welche innerhalb des Innenrohrs angeordnet sind, wobei die Permanentmagnete derart angeordnet sind, dass diese mit der Spule wechselwirken, auf. Die Sattelstütze weist einen Energiespeicher, welcher energiewirksam mit der Spule verbunden ist, auf. Die Sattelstütze weist einen Aktor, welcher energiewirksam mit dem Energiespeicher verbunden ist, wobei der Aktor dazu eingerichtet ist, eine Verschiebung des Innenrohrs entlang der Verschiebeachse zu aktuie- ren, auf. Based on the above object, the present invention proposes a seat post for a vehicle having the features of claim 1 and a vehicle having the features of claim 6 . Further advantageous refinements and developments emerge from the dependent claims. A seat post for a vehicle has an outer tube in which an inner tube is mounted so as to be displaceable along a displacement axis. The seat post has a coil located inside the outer tube. The seat post has a plurality of permanent magnets arranged within the inner tube, the permanent magnets being arranged to interact with the coil. The seat post has an energy store which is connected to the coil in an energy-efficient manner. The seat post has an actuator which is connected to the energy store in an energy-efficient manner, the actuator being set up to actuate a displacement of the inner tube along the displacement axis.
Unter „Fahrzeug“ sind hierbei sämtliche Arten Fahrzeugen zu verstehen, die einen Sattel aufweisen, auf welchem der Fahrzeugnutzer während der Fahrt sitzt. Vom Begriff „Fahrzeug“ sind somit beispielsweise umfasst: Fahrräder mit elektrischer Antriebseinrichtung wie E-Bikes, Pedelecs, S-Pedelecs, Cargobikes, Velomobile, aber auch Fahrräder ohne elektrische Antriebseinrichtung, sowie Kleinkrafträder o. ä. “Vehicle” is understood to mean all types of vehicles that have a saddle on which the vehicle user sits while driving. The term “vehicle” therefore includes, for example: bicycles with an electric drive system such as e-bikes, pedelecs, speed pedelecs, cargo bikes, velomobiles, but also bicycles without an electric drive system, as well as mopeds or similar.
Die Sattelstütze weist, wie üblich, das Außenrohr und das Innenrohr auf. Das Innenrohr ist im Außenrohr derart gelagert, dass dieses entlang der geraden Verschiebeachse verschoben werden kann. Das Innenrohr kann in anderen Worten kolbenartig aus dem Außenrohr hinaus und in das Außenrohr hinein verschoben werden. Das Innenrohr ist in dem Außenrohr gefedert gelagert. Diese Federung kann beispielsweise mittels einer mechanischen Federung, mittels einer pneumatischen Federung oder mittels einer hydraulischen Federung ausgebildet sein. As usual, the seat post has the outer tube and the inner tube. The inner tube is mounted in the outer tube in such a way that it can be moved along the straight axis of displacement. In other words, the inner tube can be pushed out of the outer tube and into the outer tube in the manner of a piston. The inner tube is spring-mounted in the outer tube. This suspension can, for example, be in the form of a mechanical suspension, a pneumatic suspension or a hydraulic suspension.
Das Innenrohr der Sattelstütze ist derart ausgebildet, dass auf diesem ein Sattel befestigt werden kann, wenn die Sattelstütze in einem Fahrzeug verwendet wird. Die Befestigung des Sattels auf der Sattelstütze erfolgt in handelsüblicher Art und Weise. The inner tube of the seat post is designed in such a way that a saddle can be attached to it when the seat post is used in a vehicle. The saddle is attached to the seat post in a standard manner.
Die Sattelstütze weist die Spule, welche innerhalb der Außenrohrs angeordnet ist, auf. Die Spule ist derart innerhalb des Außenrohrs angeordnet, dass das Innenrohr innerhalb der Spule geführt werden kann und sich entlang der Verschiebeachse ver- schieben kann. Selbstverständlich kann die Sattelstütze auch mehr als eine Spule aufweisen. Beispielsweise kann die Sattelstütze zwei oder drei Spulen aufweisen, die hintereinandergeschaltet sind. The seat post has the coil, which is arranged inside the outer tube. The coil is arranged inside the outer tube in such a way that the inner tube can be guided inside the coil and can be displaced along the displacement axis. can push. Of course, the seat post can also have more than one coil. For example, the seat post can have two or three coils connected in series.
Die Sattelstütze weist zudem mehrere Permanentmagnete, welche innerhalb des Innenrohrs angeordnet sind, auf. Diese Permanentmagnete sind derart innerhalb des Innenrohrs angeordnet, dass diese mit der Spule wechselwirken. Die Permanentmagnete formen gemeinsam mit der Spule in anderen Worten eine Vorrichtung zur Energiebereitstellung aus. Vorzugsweise sind nur in demjenigen Bereich des Innenrohrs Permanentmagnete vorgesehen, der sich trotz Verschiebung des Innenrohrs stets innerhalb der Spule des Außenrohrs befindet. Alternativ dazu können die Permanentmagnete auch außerhalb dieses Bereichs angeordnet sein. Die Permanentmagnete sind vorzugsweise ringförmig ausgebildet. In radialer Richtung ausgehend von der Verschiebeachse ist die Anordnung somit folgendermaßen: Permanentmagnete, Rohrwand des Innenrohrs, Spule, Rohrwand des Außenrohrs. The seat post also has several permanent magnets, which are arranged inside the inner tube. These permanent magnets are arranged inside the inner tube in such a way that they interact with the coil. In other words, the permanent magnets together with the coil form a device for supplying energy. Permanent magnets are preferably only provided in that area of the inner tube which is always located within the coil of the outer tube despite displacement of the inner tube. As an alternative to this, the permanent magnets can also be arranged outside of this area. The permanent magnets are preferably ring-shaped. In the radial direction, starting from the displacement axis, the arrangement is thus as follows: permanent magnets, tube wall of the inner tube, coil, tube wall of the outer tube.
Bewegt sich nun das Innenrohr innerhalb des Außenrohrs aufgrund einer Kraft, die in Richtung der Verschiebeachse auf das Innenrohr wirkt, wird also Hubarbeit verrichtet, wird durch die Bewegung der Permanentmagnete innerhalb der Spule eine Spannung induziert und somit elektrische Energie bereitgestellt. Diese Kraft wird bei Verwendung der Sattelstütze in einem Fahrzeug durch das Gewicht des Nutzers, der auf dem Sattel sitzt und mit dem Fahrzeug fährt, verursacht. Die Kraft kann alternativ auch durch eine manuelle Bewegung des Sattels nach unten und oben (Pumpbewegung) aufgebracht werden. Durch das Einfedern der Sattelstütze während der Fahrt mit dem Fahrzeug wird die Hubarbeit wiederholt verrichtet. If the inner tube now moves within the outer tube due to a force that acts on the inner tube in the direction of the displacement axis, i.e. lifting work is performed, a voltage is induced within the coil by the movement of the permanent magnets and electrical energy is thus provided. When the seat post is used in a vehicle, this force is caused by the weight of the user sitting on the saddle and driving the vehicle. Alternatively, the force can also be applied by manually moving the saddle up and down (pumping movement). The lifting work is carried out repeatedly by compressing the seat post while driving the vehicle.
Die Sattelstütze weist zudem den elektrischen Energiespeicher auf, welcher energiewirksam mit der Spule verbunden ist. Der Energiespeicher ist vorzugsweise innerhalb des Außenrohrs angeordnet. Alternativ dazu kann der Energiespeicher außerhalb des Außenrohrs angeordnet sein. Außerdem alternativ dazu kann der Energiespeicher unterhalb des Verschiebebereichs des Innenrohrs angeordnet sein. Alternativ dazu kann der Energiespeicher ringförmig ausgebildet sein, so dass das Innenrohr innerhalb des Energiespeichers verschoben werden kann. Der Verschiebebereich des Innenrohrs bezeichnet hierbei denjenigen Bereich, in welchem das Innenrohr verschoben werden kann. Die Grenzen des Verschiebebereichs sind durch die Maximalausschiebung und die Minimalausschiebung des Innenrohrs festgelegt. The seat post also has the electrical energy store, which is connected to the coil in an energy-efficient manner. The energy store is preferably arranged inside the outer tube. As an alternative to this, the energy store can be arranged outside of the outer tube. Furthermore, as an alternative to this, the energy store can be arranged below the displacement area of the inner tube. As an alternative to this, the energy storage device can be designed in the form of a ring, so that the inner tube can be displaced within the energy storage device. The panning area of the inner tube refers to that area in which the inner tube can be moved. The limits of the displacement range are defined by the maximum and minimum displacement of the inner tube.
„Energiewirksam verbunden“ heißt in diesem Zusammenhang, dass Energie von einer ersten Komponente, die die Energie bereitstellt, in eine zweite Komponente, die die Energie nutzt oder speichert, geleitet werden kann. Die Energiewirksame Verbindung kann entweder direkt erfolgen, ober über ein zwischengeschaltetes Bauelement. Vorzugsweise erfolgt die Verbindung zwischen der Spule und dem elektrischen Energiespeicher über einen zwischengeschalteten Converter, vorzugsweise über einen AC/DC-Converter. Der Energiespeicher speichert somit die Energie, die durch das Zusammenwirken der Spule und der Permanentmagnete aufgrund der verrichteten Hubarbeit an dem Innenrohr der Sattelstütze bereitgestellt wird. In this context, “energy-efficiently connected” means that energy can be conducted from a first component that provides the energy to a second component that uses or stores the energy. The energy-efficient connection can be made either directly or via an intermediate component. The connection between the coil and the electrical energy store is preferably made via an interposed converter, preferably via an AC/DC converter. The energy store thus stores the energy that is provided by the interaction of the coil and the permanent magnets due to the lifting work performed on the inner tube of the seat post.
Die Sattelstütze weist den Aktor, welcher energiewirksam mit dem Energiespeicher verbunden ist, auf. Der Aktor ist entweder direkt energiewirksam mit dem Energiespeicher verbunden oder über einen zwischengeschalteten Converter. Dieser weitere Converter ist vorzugsweise als AC/DC-Converter ausgeformt. Der Aktor nutzt somit die Energie, die durch den elektrischen Energiespeicher bereitgestellt wird. The seat post has the actuator, which is connected to the energy store in an energy-efficient manner. The actuator is either directly connected to the energy store in an energy-efficient manner or via an interposed converter. This further converter is preferably in the form of an AC/DC converter. The actuator thus uses the energy that is provided by the electrical energy store.
Der Aktor ist dazu eingerichtet, die Verschiebung des Innenrohrs entlang der Verschiebeachse zu aktuieren. Mittels des Aktors kann die Verschiebung des Innenrohrs aus dem Außenrohr hinaus und in das Außenrohr hinein aktuiert werden. Der Aktor wird mittels einer Steuereinrichtung angesteuert, die wiederum durch den Nutzer der Fahrzeugs angesteuert werden kann. Die Steuereinrichtung ist signalwirksam mit dem Aktor verbunden. „Signalwirksam verbunden“ bedeutet, dass ein Signalaustausch zwischen dem Aktor und der Steuereinrichtung erfolgen kann. The actuator is set up to actuate the displacement of the inner tube along the displacement axis. The displacement of the inner tube out of the outer tube and into the outer tube can be actuated by means of the actuator. The actuator is controlled by a control device, which in turn can be controlled by the user of the vehicle. The control device is connected to the actuator in a signal-effective manner. “Signal-effectively connected” means that signals can be exchanged between the actuator and the control device.
Die Sattelstütze ist derart ausgeformt, dass diese während der Fahrt des Fahrzeugs bei Bedarf mittels des Aktors verstellt werden kann, also das Innenrohr ausgefahren und eingefahren werden kann. Zudem kann mittels des Aktors das Verschieben des Innenrohrs blockiert werden. Die Sattelstütze kann also in anderen Worten verriegelt werden. Vorteilhaft an der hier dargestellten Sattelstütze ist, dass diese autark von einer externen Energieversorgung ist. Ein Laden des elektrischen Energiespeichers mittels einer externen Energiequelle im Falle eines Akkumulators, oder ein Austauschen des elektrischen Energiespeichers im Falle einer Batterie entfällt. Zudem wird kein zusätzlicher Bauraum benötigt, da sowohl der Energiespeicher als auch die Vorrichtung zur Energiebereitstellung, die ausgeformt ist mittels der Spule und der Permanentmagnete, in die Sattelstütze integriert sind. Des Weiteren muss der elektrische Energiespeicher nicht von außen zugänglich ausgestaltet sein. The seat post is shaped in such a way that it can be adjusted as required by means of the actuator while the vehicle is being driven, ie the inner tube can be extended and retracted. In addition, the displacement of the inner tube can be blocked by means of the actuator. In other words, the seat post can be locked. The advantage of the seat post shown here is that it is self-sufficient from an external power supply. There is no need to charge the electrical energy store using an external energy source in the case of an accumulator, or to replace the electrical energy store in the case of a battery. In addition, no additional installation space is required since both the energy store and the device for providing energy, which is formed by means of the coil and the permanent magnets, are integrated into the seat post. Furthermore, the electrical energy store does not have to be designed to be accessible from the outside.
Nach einer weiterbildenden Ausführungsform ist die Spule über den Converter energiewirksam mit dem Energiespeicher verbunden. Der Converter ist als AC/DC- Converter ausgeformt. Mittels des Converters ist es möglich, den elektrischen Energiespeicher mit der durch die Vorrichtung zur Energiebereitstellung bereitgestellten Energie aufzuladen. Dies wurde bereits in der vorangehenden Beschreibung beschrieben. According to a further developing embodiment, the coil is connected to the energy store in an energy-effective manner via the converter. The converter is designed as an AC/DC converter. Using the converter, it is possible to charge the electrical energy store with the energy provided by the energy supply device. This has already been described in the previous description.
Nach einer weiterbildenden Ausführungsform ist der Aktor über einen weiteren Converter energiewirksam mit dem Energiespeicher verbunden. Der weitere Converter ist als AC/DC-Converter ausgeformt. Mittels des weiteren Converters ist es möglich, den Aktor mit der durch den elektrischen Energiespeicher bereitgestellten Energie zu versorgen. Dies wurde bereits in der vorangehenden Beschreibung beschrieben. According to a further embodiment, the actuator is connected in an energy-efficient manner to the energy store via a further converter. The other converter is in the form of an AC/DC converter. Using the additional converter, it is possible to supply the actuator with the energy provided by the electrical energy store. This has already been described in the previous description.
Nach einer weiterbildenden Ausführungsform ist der Energiespeicher innerhalb des Außenrohrs angeordnet. In einer ersten Variante ist der Energiespeicher unterhalb des Verschiebebereichs des Innenrohrs angeordnet. Der Energiespeicher kann beispielsweise zylinderförmig ausgebildet sein, so dass dieser in das Außenrohr eingepasst werden kann. Selbstverständlich ist auch eine quaderförmige, würfelförmige oder sonstige Ausformung möglich. In einer zweiten Variante ist der elektrische Energiespeicher ringförmig ausgebildet, so dass das Innenrohr innerhalb des Energiespeichers verschoben werden kann. Dadurch ist es möglich, den Energiespeicher im Verschiebebereich des Innenrohrs anzuordnen. Nach einer weiterbildenden Ausführungsform ist der Energiespeicher mittels eines Akkumulators oder mittels Superkondensatoren ausgeformt. Der elektrische Energiespeicher kann beispielsweise als Lithium-Ionen-Akkumulator, als Natrium-Ionen-According to a further embodiment, the energy store is arranged inside the outer tube. In a first variant, the energy store is arranged below the displacement area of the inner tube. The energy store can, for example, be cylindrical so that it can be fitted into the outer tube. Of course, a cuboid, cube-shaped or other shape is also possible. In a second variant, the electrical energy store is ring-shaped, so that the inner tube can be moved within the energy store. This makes it possible to arrange the energy store in the displacement area of the inner tube. According to a further embodiment, the energy store is formed by means of an accumulator or by means of supercapacitors. The electrical energy store can be used, for example, as a lithium-ion battery, as a sodium-ion
Akkumulator, als Aluminium-Ionen-Akkumulator oder als anderer geeigneter Akkumulator ausgebildet sein. Alternativ dazu kann der elektrische Energiespeicher mittels mehrerer, miteinander verschalteter Superkondensatoren ausgebildet sein. Accumulator, be designed as an aluminum ion battery or other suitable battery. As an alternative to this, the electrical energy store can be formed by means of a plurality of supercapacitors connected to one another.
Ein Fahrzeug weist eine Sattelstütze auf, die wie in der vorherigen Beschreibung beschrieben ausgeformt ist. Das Fahrzeug kann beispielsweise ausgeformt sein als Fahrrad mit elektrischer Antriebseinrichtung wie ein E-Bike, Pedelec, S-Pedelec, Cargobike, Velomobil, aber auch als Fahrrad ohne elektrische Antriebseinrichtung, sowie als Kleinkraftrad o. ä. A vehicle has a seat post shaped as described in the previous description. The vehicle can be designed, for example, as a bicycle with an electric drive device such as an e-bike, pedelec, speed pedelec, cargo bike, velomobile, but also as a bicycle without an electric drive device, as well as a moped or similar.
Das Fahrzeug weist einen Sattel auf, der auf dem Innenrohr der Sattelstütze befestigt ist. Auf dem Sattel sitzt der Nutzer des Fahrzeugs während der Fahrt. The vehicle has a saddle mounted on the inner tube of the seat post. The user of the vehicle sits on the saddle while driving.
Durch die auf den Sattel aufgebrachte Gewichtskraft des Fahrzeugnutzers wird während der Fahrt des Fahrzeugs Hubarbeit verrichtet, da das Innenrohr während der Fahrt wiederholt einfedert. Dadurch bewegt sich das Innenrohr im Außenrohr auf und ab, so dass auch die Permanentmagnete in der Spule auf und ab bewegt werden. Dadurch wird in der Spule eine Spannung induziert und somit Energie bereitgestellt, die im elektrischen Energiespeicher gespeichert werden kann. Due to the weight of the vehicle user applied to the saddle, lifting work is performed while the vehicle is in motion, since the inner tube deflects repeatedly while driving. As a result, the inner tube moves up and down in the outer tube, so that the permanent magnets in the coil are also moved up and down. This induces a voltage in the coil and thus provides energy that can be stored in the electrical energy store.
Zusätzlich kann die Hubarbeit manuell verrichtet werden, indem der Nutzer am Sattel und somit an der Sattelstütze eine Pumpbewegung durchführt. Dadurch bewegt sich das Innenrohr im Außenrohr ebenfalls auf und ab, so dass auch die Permanentmagnete in der Spule auf und ab bewegt werden. Dadurch wird in der Spule eine Spannung induziert und somit Energie bereitgestellt, die im elektrischen Energiespeicher gespeichert werden kann. Diese alternative Betätigung ist vorteilhaft, wenn der elektrische Energiespeicher beispielsweise wegen einer längerfristigen Standzeit entladen ist. Dadurch ist es möglich den elektrischen Energiespeicher auf einfache Art und Weise zumindest teilweise zu laden, so dass genug Energie zur Verfügung ist, um den Aktor der Sattelstütze zumindest einmalig zu betätigen und somit die Sattelstütze einzustellen. In addition, the lifting work can be performed manually by the user performing a pumping movement on the saddle and thus on the seat post. As a result, the inner tube also moves up and down in the outer tube, so that the permanent magnets in the coil are also moved up and down. This induces a voltage in the coil and thus provides energy that can be stored in the electrical energy store. This alternative actuation is advantageous if the electrical energy store is discharged, for example because it has been idle for a longer period of time. This makes it possible to charge the electrical energy store at least partially in a simple manner, so that enough energy is available to to actuate the actuator of the seat post at least once and thus adjust the seat post.
