Oberhalb diesem ist die elektrische Antriebssteuerung angeordnet. Oberhalb der elektrischen Antriebssteuerung ist die Schnellwechseleinrichtung zur Aufnahme des oder der Energiespeicher angeordnet. Dieser Aufbau und diese Anordnung ermöglicht im Besonderen eine kompakte Anordnung mit kurzen Ansteuerwegen, so dass beispielsweise hohe Schaltströme des Elektromotors und der Antriebssteuerung sehr kurz gehalten werden können.A preferred embodiment of the vehicle lift provides that a superimposed arrangement of the individual components is provided for moving the carrier up and down to the lifting column. For example, an electric motor is provided above a drive device consisting of a hydraulic unit and an overlying hydraulic control. Above this, the electric drive control is arranged. Above the electric drive control, the quick-change device for receiving the energy storage or is arranged. This structure and arrangement allows in particular a compact arrangement with short drive paths, so that, for example, high switching currents of the electric motor and the drive control can be kept very short.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass als Energiespeicher Hochleistungsakkumulatoren, insbesondere Lithium-Ionen-Batterien, vorgesehen sind. Diese können als sogenannte Wechselakkumulatoren ausgebildet sein. Aufgrund der einfachen und schnellen Wechselmöglichkeit solcher Energiespeicher kann eine Betriebsdauer von beispielsweise nur 10 oder 12 Arbeitszyklen genügen, im Vergleich zu Bleiakkumulatoren gemäß dem Stand der Technik, welche üblicherweise ca. 20 Arbeitszyklen ermöglichen.A further preferred embodiment of the invention provides that high-performance accumulators, in particular lithium-ion batteries, are provided as energy stores. These can be designed as so-called removable storage batteries. Due to the simple and quick change possibility of such energy storage, an operating time of, for example, only 10 or 12 cycles can be sufficient, in comparison to lead accumulators according to the prior art, which usually allow about 20 cycles.
Eine weitere bevorzugte Ausgestaltung der Fahrzeughebebühne sieht vor, dass an der Antriebssteuerung ein Steckanschluss für ein Lade- oder Stromversorgungskabel vorgesehen ist und die Antriebssteuerung vorzugsweise eine Ladeschaltung zur Überwachung des Ladezustandes des Energiespeichers umfasst. Dies ermöglicht, dass beispielsweise der Energiespeicher bzw. Wechselenergiespeicher in einer Ladestation und gleichzeitig der oder die in der Hubsäule angeordnete Energiespeicher geladen werden können, insbesondere wenn diese Fahrzeughebebühne im Nichtgebrauch ist.A further preferred embodiment of the vehicle lift provides that a plug connection for a charging or power supply cable is provided on the drive control and the drive control preferably comprises a charging circuit for monitoring the state of charge of the energy store. This allows, for example, the energy storage or exchange energy storage in a charging station and at the same time or the arranged in the lifting column energy storage can be loaded, especially if this vehicle lift is not in use.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung umfasst der Energiespeicher eine Energiespeichersteuerung, die an oder in einem den Energiespeicher aufnehmenden Gehäuse vorgesehen ist und den Ladezustand des Energiespeichers erfasst. Durch diese Integration können die Eigenintelligenz des Energiespeichers und das Energiemanagement verbessert werden. Diese Steuerung umfasst vorzugsweise einen Mikrocontroller, der den Ladezustand des Energiespeichers überwacht. Vorzugsweise wird für den jeweiligen eingesetzten Akkumuletor die entsprechende Ladekennlinie im Mikrocontroller abgespeichert, so dass für die Ladung und Entladung des jeweiligen Akkumulators eine verbesserte Ausnutzung ermöglicht und über diese Energiespeichersteuerung angesteuert werden kann. Gleichzeitig kann dadurch die Restladung des Energiespeichers sicher bestimmt werden, um einen vorzeitigen Ausfall oder ein Stillsetzen der Fahrzeughebebühne zu verhindern und rechtzeitig den Austausch des Energiespeichers aufgrund einer Störung oder zu geringer Restladung zu signalisieren. Hierzu kann bevorzugt eine optische, akustische oder taktile Anzeige vorgesehen sein, die zumindest signalisiert, dass ein Austausch des Energiespeichers aufgrund einer zu geringen Restladung erforderlich ist. Durch eine solche Energiespeichersteuerung können gleichzeitig während der Ansteuerung der Fahrzeughebebühne die Stromstärke und die Dauer der Stromstärke in Lade- und Entladerichtung erfasst werden. Dadurch kann auf den Ladezustand des Energiespeichers über die aktuelle Kapazität rückgeschlossen werden.According to a further preferred embodiment of the invention, the energy storage comprises an energy storage control, which is provided on or in a housing receiving the energy storage and detects the state of charge of the energy storage. Through this integration, the Eigenintelligenz the energy storage and energy management can be improved. This controller preferably comprises a microcontroller which monitors the state of charge of the energy store. Preferably, the corresponding charge characteristic is stored in the microcontroller for the particular Akkumuletor used, so that allows for the charge and discharge of the respective accumulator improved utilization and can be controlled by this energy storage control. At the same time thereby the residual charge of the energy storage can be determined safely to prevent premature failure or shutdown of the vehicle lift and timely signal the replacement of the energy storage due to a fault or low residual charge. For this purpose, an optical, acoustic or tactile display can preferably be provided, which at least signals that an exchange of the energy storage is required due to a low residual charge. By such an energy storage control, the current intensity and the duration of the current in the charging and discharging direction can be detected simultaneously during the activation of the vehicle lift. As a result, it is possible to deduce the state of charge of the energy store via the current capacity.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung umfasst der Energiespeicher eine Ladeschaltung, die in einem den Energiespeicher aufnehmenden Gehäuse vorgesehen ist. Somit kann der Energiespeicher sowohl an der Hubsäule als auch direkt an einer separaten Stromversorgungsanschlussstelle geladen werden, ohne dass eine extra Ladestation erforderlich ist. Die Ladeschaltung kann zum Einsatz für unterschiedliche Versorgungsspannungen beziehungsweise Frequenzen der Versorgungsnetze ausgelegt sein und daraus den für die Antriebssteuerung der Fahrzeughebebühne benötigten Gleichstrom transformieren.According to a further preferred embodiment of the invention, the energy store comprises a charging circuit, which is provided in a housing receiving the energy storage. Thus, the energy storage can be loaded both on the lifting column as well as directly to a separate power supply connection point without an extra charging station is required. The charging circuit can be designed for use for different supply voltages or frequencies of the supply networks and transform therefrom the DC power required for the drive control of the vehicle lift.
Des Weiteren weist der Energiespeicher bevorzugt zumindest eine Datenschnittstelle, insbesondere eine drahtlose Datenschnittstelle, auf, die mit der Antriebssteuerung kommuniziert. Somit kann eine unmittelbare Übermittlung der Daten zwischen der Antriebssteuerung und dem Mikrocontroller des Energiespeichers erfolgen. Alternativ kann auch eine drahtgebundene Übermittlung der Daten vorgesehen sein, wobei bevorzugt in dem den Energiespeicher aufnehmenden Gehäuse ein Steckkontakt angebracht ist, der an einem komplementären Steckkontakt der Schnellwechseleinrichtung angreift.Furthermore, the energy store preferably has at least one data interface, in particular a wireless data interface, which communicates with the drive control. Thus, an immediate transfer of data between the drive control and the microcontroller of the energy storage can take place. Alternatively, a wired transmission of the data may be provided, wherein preferably in the energy storage housing receiving a plug contact is mounted, which engages a complementary plug contact of the quick-change device.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Schnellwechseleinrichtung, insbesondere der Aufnahmeraum der Schnellwechseleinrichtung, an einer Leiterplatte befestigt ist, welche Leiterbahnen aufweist, die zur Antriebssteuerung und/oder zum Elektromotor der Antriebseinrichtung oder zur hydraulischen Steuerung führen. Solche Leiterplatten weisen den Vorteil auf, dass auf traditionelle Verdrahtungen mittels einzelnen Kabeln verzichtet werden kann. Vielmehr ist eine gedruckte oder geätzte Platine vorgesehen, welche die entsprechenden Leiterbahnen umfasst, um die einzelnen Komponenten miteinander zu verbinden. Dadurch ist die Montage erheblich vereinfacht. Gleichzeitig kann ein modularer Aufbau erheblich verbessert werden, da entlang der Leiterplatte definierte Anschlusskontakte oder Kontaktelemente für die anzuschließenden Komponenten vorgesehen sind. Die Energie wird dann anstelle über Verbindungskabel über diese Leiterplatte übertragen. Eine modifizierte Ausführungsform dieser Leiterplatte kann dabei so vorgesehen sein, dass beim Anbringen der Leiterplatte an der Hubsäule die Hubsäule selbst als Leiter ausgebildet ist, wie dies beispielsweise bei der Karosserie von Automobilen bekannt ist.A further preferred embodiment of the invention provides that the quick-change device, in particular the receiving space of the quick-change device, is attached to a printed circuit board having printed conductors, which lead to the drive control and / or to the electric motor of the drive device or to the hydraulic control. Such printed circuit boards have the advantage that traditional wiring by means of individual cables can be dispensed with. Rather, a printed or etched board is provided, which comprises the corresponding conductor tracks to connect the individual components together. As a result, the assembly is considerably simplified. At the same time, a modular design can be considerably improved, since defined connection contacts or contact elements for the components to be connected are provided along the printed circuit board. The energy is then transmitted through this PCB instead of via connecting cable. A modified embodiment of this circuit board can be provided so that when attaching the circuit board to the Lifting column, the lifting column itself is designed as a ladder, as is known for example in the body of automobiles.
Eine weitere bevorzugte Ausgestaltung der Leiterplatte sieht auf dieser Leiterplatte Stromsensoren vor, durch welche der Ladezustand des jeweiligen Energiespeichers erfassbar ist. Dabei wird bevorzugt die Differenzspannung zwischen der Eingangsspannung der Leiterbahn am Energiespeicher und der Ausgangsspannung an der Antriebssteuerung erfasst. Aufgrund des vorbekannten Widerstandes über die Dicke und Länge der Leiterbahn kann der Strom des Energiespeichers ermittelt und somit der Ladezustand erfasst werden. Des Weiteren kann bevorzugt anstelle einer Integration der Ladeschaltung am Energiespeicher auch zusätzlich die Leiterplatte eine Ladeschaltung umfassen, so dass über einen Anschlusskontakt an der Leiterplatte ein Ladevorgang des beziehungsweise der jeweiligen Energiespeicher über die Ladeschaltung der Leiterplatte durchgeführt werden kann.A further preferred embodiment of the printed circuit board provides current sensors on this printed circuit board, by means of which the state of charge of the respective energy store can be detected. In this case, the differential voltage between the input voltage of the conductor track on the energy store and the output voltage on the drive controller is preferably detected. Due to the known resistance over the thickness and length of the conductor, the current of the energy storage can be determined and thus the state of charge can be detected. Furthermore, instead of integrating the charging circuit on the energy store, the printed circuit board may also preferably comprise a charging circuit, so that charging of the respective energy store via the charging circuit of the printed circuit board can be carried out via a connection contact on the printed circuit board.
Eine weitere bevorzugte Ausgestaltung der Fahrzeughebebühne sieht vor, dass der Energiespeicher eine Schnellwechseleinrichtung in Form eines Anschlusssteckers aufweist, der mit einem komplementären Stecker der Antriebssteuerung und/oder der Antriebseinrichtung zusammensteckbar ist. Auch diese Anordnung ermöglicht, dass ein schneller Wechsel erfolgt. Beispielsweise kann eine Fahrzeughebebühne vollständig mit den Komponenten bestückt und versehen werden und erst vor Ort durch das Zusammenstecken der beiden Steckerelemente der Schnellwechseleinrichtung die Antriebssteuerung und/oder die Antriebseinrichtung über die Batteriespannung versorgt werden. Dabei kann der an dem Energiespeicher anbringbare Stecker zwei Anschlusspole für Plus und Minus aufweisen, die in einfacher Weise an den Polen des Energiespeichers aufsteckbar oder daran positionierbar sind.A further preferred embodiment of the vehicle lift provides that the energy store has a quick-change device in the form of a connection plug which can be plugged together with a complementary plug of the drive control and / or the drive device. This arrangement also allows a quick change takes place. For example, a vehicle lift can be completely equipped with the components and provided and only on site by the mating of the two connector elements of the quick-change device, the drive control and / or the drive means are powered by the battery voltage. In this case, the attachable to the energy storage plug can have two terminal poles for plus and minus, which can be plugged or positioned at the poles of the energy storage in a simple manner.
