Description

The invention relates to a battery assembly for an electrically driven motor scooter according to claim 1.Motor wheels or motor scooters equipped with electric drives are known. Purely by way of example, reference is made to EP 1 857 314 A2. Corresponding electrically driven motor wheels or motor scooters usually have a body and at least two wheels, wherein one of the wheels is driven via an electric drive, which is supplied via a battery. For charging a battery, substantially more time is required than for full refueling of motor vehicles operated with an internal combustion engine. In this respect, the charging of a rechargeable battery should take place as far as possible when the electric motor vehicle is not required for a foreseeable time. The motor vehicle / scooter cannot be used in this charging time of the battery.DE 10 2011 111 537 A1 describes a battery housing which can be separated from an electric vehicle and which has an integrated transport device, so that the battery housing can be transported outside the electric vehicle. The battery can be moved into the electric vehicle with the aid of the transport device.DE 696 15 908 T2 discloses a battery-driven motorcycle and a battery changing device. The battery housing is connected to a seat frame, wherein the seat frame is rotatably supported together with the battery housing, such that access to the battery is enabled in an upwardly rotated position.In contrast, WO 2009 / 144 525 A1 describes a caliper assembly which can be released by an electric scooter and has a drive battery. The saddle assembly has expandable handles, so that this saddle assembly can be transported as a type of trolley in the state detached from the scooter.US 2011 / 0 042 156 A1, on the other hand, teaches a battery holder of an electric bicycle. The battery mount may be positioned and removed from the tube opening in the seat tube of the frame of the electric bicycle. The bicycle seat is connected to the battery mount via a seat post.Proceeding from this prior art, it is an object of the present invention to provide a battery assembly which can be removed from a motor scooter as simply as possible and without great effort, so that the motor scooter can be equipped with a fully charged battery or a fully charged battery assembly.It is also an object of the present invention to design a battery assembly in such a way that it can also fulfil further objects in addition to its primary object, namely the supply of energy to an electric drive. In this case, the battery assembly should be further developed in such a way that it serves as a type of mobile office.Furthermore, it is the object of the present invention to specify an improved motor scooter which has a battery assembly according to the invention.According to the invention, this object is achieved with respect to the battery assembly by the subject matter of claim 1 and with respect to an electrically drivable motor scooter by the subject matter of claim 11.Advantageous and practical embodiments of the battery assembly according to the invention are specified in the dependent claims.The object mentioned is achieved by a battery assembly which is designed for an electric motor scooter. The battery assembly comprises:at least one battery housing;at least one, in particular rechargeable, battery;at least one releasable mechanical lock for connecting the battery housing to a unit to be supplied with electrical energy, in particular for connecting to an electric motor scooter; andat least one stand device which is designed to be fold-out and / or pivotable out and / or extendable.A saddle is formed on the cover section side of the battery housing, wherein the stand device is arranged and / or formed in such a way that the saddle, in a folded-out and / or pivoted-out and / or extended state of the stand device and in the state detached from the electric motor scooter, runs horizontally to a storage surface and the battery assembly can be used as a seat, wherein the stand device consists of at least one stand leg and is secured by means of a clamping device in a folded-out and / or pivoted-out and / or extended state. The tensioning device is designed as a strap and / or cable pull, which is / is surrounded by an elastic element which is formed from rubber-like material.According to the invention, it is thus possible that the battery assembly can be easily shut down by means of the stand device in a state detached from the unit to be supplied.The stand device enables the battery assembly to be used as a seating, in particular as a hook, by means of the stand device in a state detached from the unit to be supplied.It is possible that the stand device is telescopic. In this case, the stand device is preferably arranged at least partially within the battery housing in a pushed-together state, i.e. in the non-telescoping state.In a state of the battery assembly connected to the unit to be supplied, the stand device is preferably folded in and / or pivoted in and / or retracted.If the stand device is designed to be pivotable and / or pivotable, it can be connected to the battery housing, for example, by means of a swivel joint and / or by means of a hinge.The stand device consists of at least one stand leg. The stand leg can be formed from a tube, for example from a round tube or a square tube. Furthermore, it is possible for the stand leg to be formed so as to be solid, i.e. without forming a hollow section.The at least one stand leg can comprise two sections arranged or formed obliquely to one another. These sections can, for example, form a substantially L-shaped stand leg. Furthermore, it is possible for the two sections to enclose an angle which is greater than 90°, in particular greater than 100°, in particular greater than 110°, in particular greater than 120°, and is less than 160°, in particular less than 150°.The at least one stand leg can have a flange, in particular a transverse flange, at a longitudinal end. The flange, in particular the transverse flange, enables a force introduction when the stand device is in the folded-out and / or pivoted-out and / or extended state. In addition, a flange, in particular a transverse flange, prevents the stand device from sinking into a storage area, in particular into an unfixed and / or moist floor. Alternatively or additionally, a buffer, in particular a rubber buffer, can be formed at a longitudinal end.The stand device can comprise, for example, at least two stand legs, wherein the stand legs are preferably connected to one another via at least one cross strut.If the stand device is designed to be pivotable out, the stand legs can each be connected at one longitudinal end to the battery housing by means of a pivot joint and / or by means of a hinge. Preferably, flanges, in particular transverse flanges, or buffers, in particular rubber buffers, are formed at the further longitudinal ends of the stand legs.In the case of the formation of a plurality of stand legs, it is also possible for these to be formed from a tube, for example from a round tube or a square tube. Furthermore, it is possible for the stand legs to be formed so as to be solid, i.e. without forming a hollow section. It is possible that the stand legs consist only of one section. The section can be both straight and curved. In a further embodiment of the invention, it is possible for the stand legs to each comprise two cut-outs arranged or formed obliquely with respect to one another.Furthermore, at least one cross strut is provided. The cross strut stabilizes the stand device. Furthermore, it is possible for at least two cross struts to be formed.A stand leg or the stand legs can / can be arranged in the sense of a camber. An angle can be formed between the perpendicular to the placement surface and the stand leg central plane. Preferably, a stand leg or the stand legs are arranged in the sense of a negative fall. In other words, at least one stand leg can extend obliquely outwards in the direction of the placement surface starting from the fastening point of the stand leg on the battery housing. This enables a better standing of the battery assembly with the stand device pivoted out and / or pivoted out and / or extended.The stand device is secured by means of a clamping device in a folded-out and / or pivoted-out and / or extended state. For example, the clamping device can be a spring-like element.The clamping device is preferably fastened at one end to the battery housing, in particular to a housing reinforcement. At the further end, the clamping device is preferably connected to the stand device. It is possible here for the clamping device to be connected to a stand leg and / or to a cross strut. Preferably, the clamping device is connected at one end to the battery housing and at the other end to a cross strut of the stand device.The clamping device is preferably designed in such a way that it limits the maximum folding out and / or pivoting out and / or pulling out of the stand device. Thus, in the folded-out and / or pivoted-out and / or extended state, a further movement of the stand device, in particular of a stand leg of the stand device, is prevented.The clamping device comprises at least one elastic element and at least one rigid or partially elastic element. A rigid or partially elastic element limits the maximum expansion of the clamping device. A rigid or partially elastic element thus enables a maximum movement radius of the stand device. The elastic element enables a simple folding and / or pivoting and / or retracting of the stand device. If no force is exerted on the stand device and is moved in the direction of the original position, i.e. the folded-in and / or pivoted-in and / or retracted position, the elastic element enables a force-preserving folding-in and / or pivoting-in and / or retracting of the stand device. The initially tensioned / prestressed tensioning device is retracted due to the elastic element.The tensioning device is designed as a strap and / or cable pull. In particular, the tensioning device is designed as a cable pull, which is surrounded by a rubber-like material. The cable pull represents a rigid or partially elastic element. The rubber-like material, on the other hand, constitutes an elastic element.The battery housing can have a housing reinforcement which is formed in particular in the region of a base section of the battery housing. The housing reinforcement can be made of a correspondingly more robust material and / or a correspondingly formed material. Preferably, the housing reinforcement is designed in the form of an angled and / or curved rail. This rail can be connected in particular to the base section of the battery housing.The housing reinforcement makes it possible to be able to use the battery assembly as a seat even in the state separated from the unit to be supplied.In particular, the base portion of the battery housing is designed or further developed in such a way that, for stability reasons, no support of the base portion of the battery housing on a frame part of a motor vehicle, in particular of a motor scooter, is necessary. The housing reinforcement may include two portions disposed at an angle of at least 90° to each other. The two sections are preferably formed at an angle of at least 100°, in particular at least 110°, in particular at least 120°, in particular at least 140°, in particular at least 150°, with respect to one another. The two sections can each themselves have a curved shape.It is possible for the stator device to have a shape complementary to the housing reinforcement and / or to the housing outer wall of the battery housing. If the stand device has a shape complementary to the housing outer wall, this stand device can abut the housing outer wall in a space-saving manner in the folded-in and / or pivoted-in and / or retracted state.It is also possible for the battery housing to have at least one recess, wherein the stand device can be mounted in the at least one recess in the folded-in and / or pivoted-in and / or retracted state. It is also possible for the stator device to have a shape complementary to a possibly formed housing reinforcement. The stator device can thus be formed as part of the housing outer wall in the unused state. The stand device may have an angled and / or curved shape.Furthermore, it is possible for the stator device to be fastened to the housing reinforcement. A pivot joint and / or a hinge and / or a fastening portion of the stand device may / may be connected to the housing reinforcement. This prevents a force introduction of the stator device into a battery housing section which is made solely of plastic.A (separate or separate) battery capsule, for example in the form of a battery case, can be arranged in the battery housing. The battery case preferably contains the battery packs and the associated (power) electronics. The battery case is preferably made of a more robust material than the battery housing. Preferably, the battery case is so stable that it serves as a support structure and transfers the loads applied to the seat surface of a saddle to the vehicle body. The battery case can be formed at least partially from metal, for example from an aluminum alloy, whereas the battery housing can consist of a plastic.Preferably, a saddle of the battery assembly in a raised state, i.e. with the stand device pivoted out and / or pivoted out and / or extended, is oriented at the same angle as in the driving mode or driving state of the battery assembly. In other words, the stand device is arranged and / or designed in such a way that the (elongate) saddle, in a folded-out and / or pivoted-out and / or extended state of the stand device, runs (substantially) horizontally to a storage surface.A circuit is preferably formed in the battery housing.In a further embodiment of the invention, the battery assembly comprises at least one actuating element which is designed to be able to be folded out of the battery housing and / or pivoted out and / or extended, in particular telescopic.The battery assembly can be actuated, in particular pulled or pushed, by an extendable and / or fold-out and / or pivotable actuating element.The actuating element can be designed as a lever or as a handle, in particular as a bow-type handle. The handle preferably has a gripping section which can be gripped in particular by the complete hand. Preferably, the gripping portion merges into at least one, preferably two, extension portion(s). The at least one extension portion may be a rod-like or rail-like element. This rod-like or rail-like element is mounted in particular in or on the battery housing such that it can be folded out and / or pivoted out and / or extended, in particular telescopically.In a first state of use, which corresponds to the driving state of an electrically drivable motor vehicle, in particular an electric motor scooter, the extension section is preferably mounted completely in the battery housing.In a further state of use, which corresponds to the state of the battery assembly detached from the motor vehicle, in particular from the motor scooter, the at least one extension section can be unfolded and / or pivoted out and / or extended from the housing, so that the actuating element is in an at least partially unfolded and / or pivoted out and / or extended, in particular partially telescoping, state. This is comparable to an extended handle of a luggage case or trolley.An outwardly folded and / or outwardly pivoted and / or extendable, in particular telescoping, actuating element thus facilitates the handling of a battery assembly released from a motor scooter. The battery assembly can be drawn to a charging station, for example, with the aid of the actuating element. In a particularly preferred exemplary embodiment, the actuating element is designed as a bow grip.The battery case may include a front portion, a rear portion, two side portions connecting the front and rear portions, a lid portion, and a bottom portion.It is possible for at least one roller to be formed on the battery housing. Particularly preferably, at least two rollers are arranged on the battery housing. These are preferably formed on the front section or on the transition section from the front section to the base section of the battery housing.By means of at least two rollers, the battery assembly can be pulled particularly uniformly. The rollers can be part of the described guiding device of the battery group and / or assume this function. The rollers can thus facilitate the arrangement of the battery group on the unit to be supplied and, when arranged, can be guided in the guide device of the unit to be supplied.The at least one roller can be embodied to be retractable in the battery housing. After transporting, in particular pulling, the battery assembly, the at least one roller can be lowered, so that rolling away of the battery assembly is prevented.In particular, in the case of a folded-out and / or pivoted-out and / or extended state of the stand device, a secure standing of the battery assembly can be made possible with the aid of a roller lowered into the battery housing.In a further embodiment of the invention, the battery housing has, in the region of the actuating element, in particular in the rear portion, an engagement recess which is formed in such a way that the actuating element can be gripped around by one hand. In the state of the battery assembly connected to the motor scooter, the gripping portion of the actuating element preferably extends transversely to the direction of travel. The battery housing has a recess or engagement recess such that the actuating element can be pulled, in particular pulled up, in the clamping handle.The battery assembly can have passive cooling and / or active cooling in order to increase the efficiency of the battery located in the battery housing. The passive cooling can be, for example, an arrangement of cooling ribs. For example, the cooling fin arrangement is formed on the rear portion and / or on a / the side portion(s) of the battery housing.The passive cooling can also be at least one air inlet opening. Ambient air can be guided through a correspondingly configured air inlet opening into the battery housing during travel with a motor scooter through the at least one air inlet opening, wherein the heated air can flow out of the battery housing through at least one corresponding air outlet opening. It is possible for at least one ventilation wheel to be located in the battery housing as an active cooling. An active water cooling can also be formed within the battery housing. So-called cooling fin plates can be used as the arrangement of cooling fins.It is possible for the battery assembly to comprise a cooling duct. Such a cooling channel can be formed in particular between a / the battery case and the battery housing. Between the battery housing, which in particular comprises the housing outer wall, and the battery case, a plurality of cooling ducts can also be formed. Ambient air can flow into the cooling duct through a corresponding air inlet opening. The heated air can flow out of the cooling duct through a corresponding air outlet opening. Furthermore, a ventilation wheel or a blower can be formed in the cooling channel. Since the battery case is preferably formed from metal, the heat arising in the interior of the battery case can be dissipated in the cooling channel in the manner of a cooling plate.Preferably, the battery assembly has two cooling channels. These may extend substantially laterally. This means that the cooling channels run in the region of side surfaces of the battery housing.The battery assembly may further comprise at least one power connector. By means of a power plug, the battery assembly is electrically connected to the unit to be electrically supplied, in particular to the electric motor scooter.Preferably, the battery assembly comprises a combined power / communication plug. With the aid of such a plug, the unit to be supplied can be supplied with power or receive power from the unit. Furthermore, with the aid of such a combined power / communication plug, a communication transmission or communication connection can be established between the battery assembly and the unit to be supplied. Preferably, the combined power / communication plug has a bus interface.Furthermore, it is possible for the battery assembly to have a (separate) communication socket.The combined power / communication plug is formed on a side portion of the battery case, for example. The pins of the power / communication plug are preferably formed perpendicular to a base surface. The connection of the power / communication plug to a power / communication socket of a unit to be electrically supplied, in particular an electric motor scooter, can accordingly be effected by sliding the plug onto the socket.Preferably, a mechanical locking of the battery assembly is formed in the bottom portion of the battery housing. The mechanical locking can be designed, for example, as a locking hook. The mechanical locking is preferably actuatable by a locking actuation elementThe locking actuating element can be, for example, a cord or a chain or a band or a loop. By pulling on the cord or chain or on the band or on the loop, the mechanical locking, in particular the locking hook, can be actuated.Preferably, the locking actuating element, in particular the cord or the chain or the loop or the band, is arranged in the battery housing or within the battery housing. In the battery housing, a compartment is preferably formed on the rear section side. This compartment is preferably designed to be closable and / or lockable. By folding or lifting off a correspondingly lockable and / or lockable battery housing section, access to the compartment can be established. Preferably, a / the locking actuating element, in particular a / the cord or a / the chain or a / the band or a / the loop, is arranged in the compartment.The battery assembly may also have at least one power supply bushing for charging the at least one battery. A power socket serves for charging the at least one battery or for charging at least one battery pack. A power connector may be inserted into the at least one power receptacle such that the at least one battery pack may be charged.It is possible for a plurality of battery packs to be arranged in the battery housing. Preferably, at least two net bushes are formed. This allows for faster charging of multiple battery packs.Furthermore, the battery assembly can comprise at least one Bluetooth interface and / or at least one USB socket. It is possible that the at least one network socket and / or the at least one Bluetooth interface and / or the at least one USB socket is / are formed within a / the preferably lockable and / or lockable compartment. This enables protection against manipulation, so that only the owner of a key or access system can access a USB socket and / or a network socket to the compartment and can switch on or switch off the at least one Bluetooth interface.Programs can be loaded using a USB socket. The reading out of a fault memory is also possible with the aid of a USB socket. Furthermore, a loudspeaker arranged within the battery assembly, in particular within the battery housing, can be actuated with the aid of a Bluetooth interface and / or with the aid of a USB socket. It is possible that audio files can be sent to the battery assembly via the Bluetooth interface and / or via the USB socket.Furthermore, it is possible for the battery assembly to have an interface for charging external devices, in particular mobile communication devices, with current. The charging takes place by means of the battery of the battery assembly. Furthermore, it is possible for the battery assembly to have a device for contactless energy transmission from the battery of the battery assembly to an external device.By means of the interfaces, network sockets, Bluetooth interfaces or USB sockets which are optionally present, it is possible to use the battery assembly as a type of mobile office. With the aid of the stand device, it is possible for the user to sit comfortably on the battery assembly, in particular on the saddle of the battery assembly, while he operates his laptop, for example. This can be supplied with current by means of the battery assembly.At least one loudspeaker can be installed in the battery housing. The loudspeaker is preferably a resonant loudspeaker. Advantageously, a section of the battery housing can be designed as a resonance surface.On the battery housing, a saddle is formed on the cover portion side. A seat of a motor scooter is consequently formed as an element of the battery assembly. The saddle is preferably connected, in particular glued and / or latched, to the battery housing, in particular to the cover section of the battery housing.

The locking counter piece is preferably a locking bolt or a locking receptacle for a locking hook.The invention is described below on the basis of exemplary embodiments for an electrically drivable motor scooter, which are explained in more detail on the basis of figures.The following are shown here: FIG. 1 shows an electrically driven motor scooter in a perspective view; FIG. 2 : shows the electrically operated motor scooter of FIG. 1 in a side view; FIGS. 3 a;3 b : Side views of battery assemblies according to the invention with folded-out stand devices; FIGS. 4 a- 4 c : different perspective views with respect to a battery assembly according to the invention, according to a first embodiment; FIG. 5 : shows a transparent view with regard to the components located in the battery housing of the battery assembly; and FIG. 6 : rear frame part without a battery assembly attached.In the following description, the same reference numerals are used for the same and identically acting parts.FIGS. 1 and 2 show an overall view of a scooter 10 according to the invention. Furthermore, the body comprises a steering device 30, which enables steering of the motor scooter 10. At the lower end of the steering device 30 is the front wheel 12, and in the rear part, in particular at the rear frame part 11, there is a battery assembly 70 and a battery housing 21 associated with the battery assembly 70, which also shows a saddle 20.The battery assembly 70 comprises a battery housing 21 having a front portion 71, a rear portion 72, two side portions 73 connecting the front and rear portions 71 and 72, and a bottom portion 75 (see FIG. 4 b). Also visible is an actuating element 80 which is designed in the form of a bow grip. The gripping section 89 is arranged transversely to the direction of travel F in the state in which it is installed in the motor scooter 10.In order to enable the actuating element 80, in particular the gripping portion 89, to be encompassed around, the battery housing 21 has an engagement recess 81 in the region of the rear portion 72. This engagement recess 81 is formed in such a way that the actuating element 80, in particular the gripping section 89, can be fully gripped by the hand.FIGS. 3 aand 3 b illustrate side views of further embodiments of battery assemblies 70 according to the invention.FIG. 3 ashows a stand device 400. This is shown in the deployed state. The stator device 400 thus protrudes from the battery housing 21. The stand device is folded out with the aid of a pivot joint 405. The stand device 400 comprises two stand legs 410, wherein only one stand leg 410 can be seen in the side view. The stand legs 410 of the embodiment according to FIG. 3 aare formed straight.At the end 420 opposite the swivel joint 405, buffers 425 are formed on the stand legs 410. The buffer 425 shown by way of example in FIG. 3 acan be designed as a flange. The buffer 425 is preferably formed of a rubber-like material. The two stand legs 410 are preferably connected via a cross member 430, which is shown in dashed lines. The cross member 430 serves for stabilizing the two stand legs 410.The stand device 400 preferably comprises a clamping device 440. This clamping device is connected at a first end 441 to the battery housing 21. At the second end 442, the clamping device 440 is preferably connected to the cross member 430. The clamping device 440 limits the maximum possible fold-out position of the stand device 400 or of the stand leg 410. The tensioning device 440 comprises a cable 445. This cable pull limits the movement path of the stand leg 410.The cable 445 is preferably designed to be rigid or partially elastic, so that an extension of the clamping device 440 is not possible. The cable 445 is surrounded by an elastic element 448. This elastic member 448 has a resilient action. As soon as the battery housing 70 is lifted upward and the stand leg 410 is pivoted in in the direction of the battery housing 21, the elastic element 448 causes the stand legs 410 to be fully or partially folded in. The elastic member 448 contracts, so that the jig 440 is shortened and thus the stand legs 410 are pulled toward the battery case 21.Both a USB socket and a Bluetooth interface can be formed in the battery housing 21. Furthermore, it is possible for an interface of this type to be formed in the battery housing 21 and to enable a power charge of an external device, for example a laptop, by means of the battery of the battery assembly 70.The saddle 20 of the battery assembly 70 is oriented in the illustrated upright state, i.e. with the stand device 400 folded out, at the same angle as in the driving mode or driving state of the battery assembly 70.In particular, the elongate saddle 20 extends substantially horizontally with respect to the storage surface A.Overall, the battery assembly 70 can be used as a type of mobile office, in particular in the state detached from the unit to be supplied. The saddle 20 can be seated comfortably and can follow its activities by means of the interfaces formed in the battery housing 21. Accordingly, it is possible to make effective use of, in particular, a charging process of a battery assembly 70.FIG. 3 b shows a further embodiment of a stand device 400. The stand device 400 likewise comprises two stand legs 410, wherein only one stand leg 410 is visible in FIG. 3 b. The stand leg 410 has a shape complementary to the contour 415 of the base section 75. This means that the stand leg 410 consists of two sections 411 and 412 arranged at an angle to one another. These portions 411 and 412 are arranged obtusely to each other. This results in an angle α, as is also provided in the contour 415 of the base section 75 of the battery housing 21.Due to the two sections 411 and 412 arranged at an angle α, this stator device 400 causes a more stable standing of the battery housing 21, in which an initial resistance must be overcome in order to fold the stator device 400. With respect to the clamping device 440, the explanations listed in connection with FIG. 3 aappear.Referring now to FIGS. 4a-4c, the battery assembly 70 is illustrated. The battery assembly 70 includes two rollers 130. These rollers 130 are preferably formed on the front portion 71 and the transition portion from the front portion 71 to the bottom portion 75 and the side portions 73 of the battery case 21, respectively. By means of at least two rollers 130, the battery assembly 70 can be pulled particularly uniformly.The saddle 20 is formed as a member of the battery assembly 70. The saddle 20 is preferably connected, in particular glued and / or latched, to the battery housing 21, in particular to the cover section 74 of the battery housing 21. The saddle 20 is preferably formed of a foam material.The illustrated saddle 20 has an ergonomically advantageous shape. At least in sections, a V-shaped cross-sectional profile 180 can be seen. The cross-sectional profile 180 is preferably visible as a longitudinal section running in the direction of travel F. At least in sections, the saddle 20 can have the shape of a hyperbolic paraboloid. A cross-sectional profile is likewise formed transversely to the direction of travel F or parallel to the gripping section 89, wherein this cross-sectional profile is formed at least in sections in a U-shape.In FIG. 4 b, the bottom section 75 is shown. A depression 190 is formed in the base section 75, wherein an element of a mechanical lock 91 is formed in this depression 190 or recess. The mechanical locking 91 is a locking hook. By means of the locking hook 91, the battery assembly 70, in particular the battery housing 21, can be connected to a motor scooter 10.In the base section 75 of the battery housing 21, a guide device 85, in particular a slide-type guide device, is formed, which can be pushed or slid onto a guide device 210, in particular a rail-type guide device, of the motor scooter 10 (see FIG. 6 ).The guide device 85 of the battery housing 21 preferably merges into locking plates 140. The locking plates 140 are guided or slid on the guide device 210 of the unit 10 to be supplied.The motor scooter 10 (see FIG. 6 ) preferably has a centering aid 220.
