Definitions

  • the present invention is aimed at improving a watercraft, in particular a standing board such as a surfboard or wakeboard, with jet propulsion with electric motor drive and with an electrical energy storage for the electric motor.
  • An essential parameter for the safe operation of an electrically powered vehicle is the temperature of the battery during operation. If the battery is too warm, no more energy can be drawn and, in the worst case, driving must be stopped or damage will occur.
  • the drive and its controls are currently permanently installed in the well-known electric watercraft.
  • An error or defect that occurs usually cannot be repaired by the end user.
  • he is usually dependent on a trained technician: he then has to carry out a repair on-site at the customer's site, or the watercraft is brought to the customer for repairs at a typically certified manufacturer's service location, or it is even sent to the manufacturer for repairs.
  • repairs at the customer's premises by a trained technician are not practical because there is usually a lack of technical infrastructure and the personnel and travel costs are immense. Repairing at a service branch creates the problem of transporting the product. A prerequisite for this is a developed infrastructure with a sufficient number of service branches. This is very difficult to achieve with global sales and is therefore additionally problematic.
  • the present invention is based on the object of creating a watercraft and a drive system for it whose handling and, in particular, ease of maintenance are improved. This task is solved by a watercraft with the features of claim 1. Preferred embodiments are specified in the subclaims.
  • a watercraft according to the invention can, for example, be a standing board in the manner of a surfboard or wakeboard, i.e. set up for a user or "pilot” standing on it (and for example also with or without bindings, as are known from water skis or wakeboards).
  • feet - but also a water or underwater vehicle, that is designed not only for standing on a very limited area of the vehicle, but also for moving on or in it, standing, or even (particularly as an underwater vehicle such as an underwater scooter for towing a diver) for towing one or more people.
  • the watercraft according to the invention is equipped with a jet drive with electric motor drive and with an electrical energy storage device for the electric motor.
  • the jet drive and the electric motor drive are also integrated in a (first) structural unit, but in any case the energy storage is integrated in its own (particularly second) structural unit.
  • the second (and possibly also the first) structural unit is designed according to the invention to be assembled and dismantled in the watercraft as an integral structural unit (in particular pre-assembled and as a whole).
  • the energy storage unit can have a carrying handle that, for example, allows it to be carried upright close to the body.
  • the structural units (in particular for integration into the construction of various watercraft) preferably have a common housing into which they can be mounted and dismantled (prepared, set up, adapted and/or suitable).
  • the structural units can have a common housing, and they are prepared, set up, adapted and/or, in particular, their dimensions and connecting elements can be fitted into the housing and removed from it.
  • housing is also a frame or framework that surrounds the structural units at least in some areas.
  • first structural unit or power box
  • second structural unit or battery box
  • possibly a storage compartment (8) as a possible third structural unit in a receiving unit (which may also consist of several parts).
  • housings can be assembled - which can be integrated together (in particular as a system) into the construction of various watercraft (in particular hydrodynamically, propulsion-functionally and / or regarding the statics of the watercraft) - it is possible to use different watercraft, the same or similar watercraft of about one type, but with different hulls, lengths, buoyancy volumes, widths and/or underwater vessels, as is known from surfboards - but with the same drive system according to the invention. The customer can therefore always access these same components and can use them in all of these products.
  • the watercraft (such as a surfboard or wakeboard) can even be set up to be usable without the drive according to the invention.
  • replacement structural units which, for example, do not contain a drive device and no energy storage
  • the watercraft would then be usable again as, for example, a conventional surfboard or wakeboard - and can then be used again according to the invention by inserting the structural units according to the invention.
  • the modular structure also enables the customer to replace individual components more quickly and with less effort in the event of a fault. This can be done quickly through local sales partners. Since batteries can only be transported in... As this is usually not permitted on passenger aircraft, a user can, for example, take their surfboard without a battery on holiday and rent a battery on site from a sales partner, as transporting the surfboard (without a battery) is also permitted on passenger aircraft as sports luggage.
  • the assembly of the second structural unit it is possible for the assembly of the second structural unit to block the dismantling of the first structural unit and/or for the dismantling of the second structural unit to enable the dismantling of the first structural unit.
  • This also applies to the storage compartment according to the invention:
  • the assembly of a third structural unit (a storage compartment) blocks the dismantling of the second structural unit and the dismantling of the third structural unit enables the dismantling of the second structural unit. In this way, the blocked structural units can be more operationally safe due to their temporary inaccessibility.
  • first structural unit power box
  • This unit can then be fixed in position by installing a rear section.
  • This structural unit and/or the stern part
  • This structural unit can also have an area of an outer skin of the watercraft, namely in particular the area of the outer skin at the stern, which surrounds the outflow opening of the jet drive.
  • the second and/or the third structural unit preferably has an area of an outer skin of the watercraft.
  • the watercraft according to the invention can be set up (for example in the form of a standing surface, at least one foot binding and/or a seat) to accommodate a pilot of the watercraft.
  • a drive emergency stop actuation device can be arranged in the area of the outer skin and within reach of the pilot of the watercraft.
  • the second structural unit is prepared, set up, adapted and/or suitable for being mounted in a (suitably prepared, set up, adapted and/or suitable) housing in such a way that an unfilled cooling water cavity remains in the housing , which has an inlet for cooling water from an inlet opening.
  • This can be arranged in an outer skin of the watercraft in such a way that the water flows against it when it is traveling and allows water into the cavity. It can (for example in a transition area from the first to the second structural unit) but also, for example, be fed from an outlet opening of cooling water of the jet drive (in particular then, for example, also in a transition region from the first to the second structural unit) and therefore in a line connection with it stand or be settable.
  • the cavity then also has an outlet for the cooling water from an outlet opening, which is arranged in an outer skin of the watercraft in such a way that it releases the cooling water from the cavity when it is traveling.
  • the process can in particular be arranged in the top of the watercraft and in particular go through a joint gap, for example between the outer skin area, which is formed by the second structural unit inserted there, and the otherwise surrounding outer skin of the watercraft.
  • the cavity is then arranged for its cooling functionality, in particular next to the energy storage unit in the housing, so that heat from this unit can be exchanged with the cooling water in the cavity and can be removed from the cavity with the cooling water.
  • the power box is preferably locked from behind in a mounting slot in the housing using (for example two) screw connections. Furthermore, either another latch in the front area or screws from below will preferably ensure a secure fit and the introduction of thrust.
  • the battery box is guided to its position via a rail system. Locking is done using special locking pins. These pins hold and lock the battery box in its position.
  • the storage compartment is also preferably fixed with locking pins and at the same time secures the locking of the battery box, as it prevents the battery box from slipping forward out of its locking position.
  • Relevant system information is stored in a data memory regarding setting the performance, retrieving GPS data and error diagnosis through the user interface via an app. This includes, among other things, the driving profile with data on currents, voltages, speeds, system temperatures, serial numbers of the components used, GPS data and driving speeds.
  • the user can access the GPS data of the trips via the app and share them with their friends on social networks. He can also change the power setting, for example to enable children to drive with reduced power.
  • the user can provide a manufacturer or operator with the system data in order to receive quick help in the event of problems. This can then make changes to the parameters or tell the user exactly where the error is and whether parts may need to be replaced.
  • the gas signal is transmitted to the board via the remote control.
  • the gas signal is generated by operating the throttle lever, particularly with the index finder.
  • the remote control communicates with the board via a Bluetooth radio connection.
  • An RGB LED can be used to display various statuses to the driver while driving. These include: charge status of the remote control, connection of the remote control to the board (paired state), battery status, warnings and errors.
  • the remote control can be locked into a tether, allowing the driver to choose whether he wants to drive with or without a tether. To do this, the remote control is inserted into a rail system and locked in place using a clamp connection. The remote control is charged via induction.
  • the battery is the heart of the drive. This is monitored and maintained by an intelligent battery management system (BMS). In addition to the temperature of the battery, the BMS also monitors the voltages of the individual cell strands. If values outside the tolerance occur, the driver is informed accordingly and the system is switched off if necessary to avoid damage.
  • BMS intelligent battery management system
  • the individual strands of the battery are balanced.
  • the currents and voltages as well as the temperature are monitored.
  • the communication between BMS and charger ensures an optimal current/voltage characteristic to charge the battery safely and efficiently.
  • the individual battery cells are connected using copper rails instead of usual steel connectors. Through this A significantly lower internal resistance of the battery pack is achieved, which leads to an extension of the driving time.
  • the copper rails are used to connect the battery and the connector in the battery box, as well as from the connector to the speed controller in the power box. This also minimizes the line resistance, which extends the travel time.
  • the removable battery is locked using a rail system.
  • the battery box is inserted via a rail system and, when inserted, is pushed backwards to close the plug connection.
  • the plug connection is released by pushing the battery box forward, which opens a recessed grip in the rear area through which the battery box can be removed from the receiving unit.
  • the prior art here uses a locking mechanism that allows the battery to be lifted out of the board. However, this can cause the mechanism to come loose while driving and the battery to “jump out” of the board when driving over waves.
  • the storage compartment locked in front of the battery box and the rail system ensure that the battery box cannot be accidentally removed or jumped out of the board.
  • the batteries are charged via a particularly preferred charging station.
  • the battery box is placed in the charging station and can be actively cooled during charging using temperature-controlled fans installed in the charging station in order to prevent the battery cells from heating up excessively during charging.
  • the battery management system controls the voltage and current delivered by the charger. This ensures safe and efficient charging of the battery while simultaneously monitoring battery status and temperature.
  • batteries with different capacities may be available so that different driving and charging times can be achieved.
  • a rental company can use a battery with a capacity that suits its rental times, which can then be quickly recharged.
  • the speed controller, the BMS, the remote control and the GPS receiver can communicate via a CAN bus interface. This means information and data can be exchanged with each other.
  • a particularly preferred power/communications connector in particular between the first and second structural unit, it is a connector that meets the IP68 standard both when plugged in and when not plugged in. The voltage is only released to the plug when the connection is securely locked. The secure locking of the plug connection is ensured via communication contacts.
  • the connector has guide pins that ensure that the two connectors are brought together.
  • the plug connection is held in place by the locking pins, which also ensure the contact pressure required for secure locking.
  • cooling water also for cooling the battery:
  • the temperature of the battery is an essential parameter for operating the board. If the battery is too warm, it may happen that no more energy can be drawn and driving must be stopped.
  • the cooling water system in the board actively cools the battery to minimize the temperature. To do this, cooling water is introduced into the space below the battery and thus cools the battery.
  • This cooling water is particularly preferably provided by the jet drive and flows forward from the power box into the space between the fuselage and battery box, where it cools the battery housed in the battery box. The cooling water can then escape upwards, for example, through the gap between the recording unit and the battery box or backwards through the gap between the power box and the fuselage.
  • the figures show a watercraft 2 and, to drive it, a first structural unit 4, a second structural unit 6 and a third structural unit 8 in a mounting housing 10.
  • the watercraft 2 is a standing board in the style of a surfboard, i.e. set up for a user or “pilot” (not shown) to stand on it.
  • the watercraft 2 is powered by a jet drive (not shown) with an electric motor drive (not shown) and with a electrical energy storage (not shown) for the electric motor.
  • the jet drive and the electric motor drive are integrated in a first structural unit 4 and the energy storage in a second structural unit 6.
  • both structural units are set up to be assembled and dismantled in the watercraft 2 as an integral structural unit (in particular pre-assembled and as a whole).
  • the structural units 4, 6, 8 have (in particular for integration into the construction of various watercraft) a common housing 10 into which they can be mounted and dismantled (prepared, set up, adapted and suitable).
  • the structural units 4, 6, 8 have a common housing 10, and they are prepared, set up, adapted and, in particular, their dimensions and connecting elements can be fitted into the housing and removed from it.
  • the housing 10 is an outer frame with closed walls that surrounds the structural units 4, 6, 8 and only leaves openings 12 in areas 101, 102 of an outer skin of the vehicle 2.
  • the housing 10 thus forms a standardized receptacle for the replaceable energy supply unit 6 and the drive unit 4, which can be integrated into an entire family of watercraft (by means of housing 10 of the same design).
  • Fig. 1 shows an example of the basic structure and integration of such a unit in a watercraft 2, here a surfboard 2.
  • This consists of an outer shell 100, which encloses a polystyrene core 600 as a floating body.
  • a standardized recording unit 10 consisting of a storage compartment battery box recording unit (200) and power box recording unit (lid 201 and base 202) and offers space for the second structural unit 6 (battery compartment base 300 and cover 102), a storage compartment 8, 101 and the first structural unit 4 (Powerbox lid 400 and base 401).
  • the cover 102 of the battery compartment 6 is at the same time part of the outer shell or outer skin 100 of the surfboard 2 and closes (mounted) flush with this.
  • the cover 102 also contains a plug for emergency stop 500 of the drive components of the surfboard 2.
  • the power box 400, 401 contains the drive components (not shown), such as the jet, a BLDC or PMSM motor, a speed controller - and an interface plug 302.
  • the battery compartment 300, 102 contains a lithium-ion battery (not shown), a battery management system (not shown), a receiver for a remote control (both not shown), a GPS receiver and a transmitting and receiving station for communication with an APP via Bluetooth interface (not shown).
  • the storage compartment 8, 101 which is also to be placed in the battery receiving unit 200, fulfills, in addition to its actual function as a storage location, also an additional function as a locking or clamping unit for the battery compartment 6, 300, 102 and the power box 4, 400, 401 behind it.
  • On the Two slide rails are installed on the sides of the unit 200, which enable the battery box to be inserted easily and absorb the forces caused by the weight of the battery box and the driver.
  • the power box 4, 400, 401 is additionally attached by screw connections (not shown) to the rear of the power box receiving unit 201, 202 as well as in the area of the jet inlet on the underside of the board (not shown).
  • the battery compartment 6, 300, 102 is inserted into the battery receiving unit 200 from above through the opening 12 in the case 100 ( Fig. 2 ) and guided to its final position towards the rear of the vehicle by a low-play guide rail system 203.
  • the locking is carried out by guide and locking pins 303, which enable the battery compartment (battery box) 6, 300,102 to be fastened vertically.
  • an interface plug 301, 302 certified as IP 68 is closed, thereby enabling power and communication transmission between relevant components of the units 4 and 6.
  • the plug has guide pins (not shown) which ensure that the two plug elements 301, 302 are brought together. Under the Slide rails (not shown) are installed in the battery box 6, 300,102, which enable the battery box to be easily pushed.
  • the slide rails absorb the weight of the battery box (and the driver), so that the guide and locking pins 303 primarily serve for guidance without a major load-transferring function. It is locked by inserting the storage compartment, which also ensures the required contact pressure.
  • FIG. 1 Another special feature of the design is the creation of a cooling effect through a deliberately created flow of water within the vehicle body 2 ( Figure 1 ). This is achieved by inlet and outlet openings, which allow the water to flow in and out of a cavity 700 between the battery compartment 300 and the battery compartment receiving unit 200 and thus enable the battery assembly 6 to be cooled ( Fig. 3 and 4 ).
  • the inlet opening is fed with cooling water from the jet engine from an outlet opening (305).
  • the process takes place in the top of the watercraft 2 and passes through joint gaps between the outer skin area 102, which is formed by the second structural unit 6, 300, 102 inserted there, and the otherwise surrounding outer skin 100 of the watercraft 2.
  • the cavity 700 is then for its cooling functionality next to the energy storage unit 6, 300, 102 in the housing 10 arranged so that heat from this unit can be exchanged with the cooling water in the cavity 700 and removed with the cooling water from the cavity 700.
