EP3285894B1 - Drive module for a skateboard and set and skateboard with such a drive module - Google Patents

Description

The invention relates to a drive module for a skateboard, a set with such a drive module, and a skateboard which is equipped with such a drive module.

From the prior art, for example DE 10 2009 036 924 A1 and WO 2006/029044 A2 , Skateboards are already known which have an axle with at least one wheel, the wheel being electrically driven by an electric motor. The electric motor is supplied with energy via an accumulator or batteries that the skateboarder carries with him in a backpack, for example. The accumulator, which has to be carried separately, leads to restrictions in comfort for the user and also harbors a risk of injury, since a cable connection to the electric motor is required.

Alternatively, it is proposed in the prior art to integrate the energy store into the skateboard. With the fully integrated variant according to WO 2006/029044 A2 the disadvantage is that the skateboard cannot be used while the battery is charging. So that too Range of the skateboard limited. In addition, the acquisition costs of such a fully integrated skateboard are increased.

More electrically powered skateboards are out US 2014/0027192 A1 , U.S. 5,893,425 A , DE 20 2010 004 820 U1 known. However, it is driven by a belt that connects the electric motor with a wheel. Such skateboards cannot be used without electrical energy, since the belt drive acts as a resistance against manual pushing.

A skateboard with a wheel hub motor and a battery case attachable to the skateboard is off US2010 / 0222941 known.

The object of the invention is to provide a concept for an electric drive of a skateboard which provides the user with a high degree of flexibility and is characterized by ease of use. It is also an object of the invention to provide a skateboard which implements this concept.

According to the invention, this object is achieved by a drive module with the features of patent claim 1, furthermore by a set with the features of patent claim 12 and by a skateboard according to patent claim 15.

The invention proposes a drive module for a skateboard. The drive module can have at least one axle with at least one wheel, the wheel being driven by an electric motor. Furthermore, the drive module can comprise a frame which is connected to the axle. The frame has a receiving space for an energy store, in particular an accumulator. The drive module can be interchangeably connected to the skateboard.

The invention is based on the idea of providing the components for the electric drive of the skateboard as a uniformly manageable module. In particular, the uniformly manageable drive module can be used universally for a large number of skateboards, in particular for boards (decks) of skateboards. This opens up the possibility for the user to retrofit or convert his existing skateboards with an electric drive. In addition, the drive module can also be combined with different skateboards or skateboards on the production side.

The drive module essentially enables standardization, so that a large number of different skateboards, in particular longboards or slalom boards, can be equipped with the uniform drive module. This also applies to conventional or commercially available, non-powered skateboards, which can easily be retrofitted with the invention.

The interchangeability of the drive module also makes it possible to use the electric drive on different, existing or conventional skateboards. The user can therefore choose at any time which of his existing skateboards he would like to equip with the drive module.

Another advantage of the invention is that the energy store of the drive module can be exchanged. This largely eliminates the range restrictions to which electrically driven skateboards are subject from the prior art. This is because the exchangeable energy storage device enables an empty energy storage device to be replaced with a charged energy storage device in a few simple steps, so that the drive module continues to be operational. The removed, emptied energy store can then be charged independently of the drive module. In addition, the interchangeability of the energy store offers the possibility of offering the user different energy stores, for example with different energy storage capacities.

The frame of the drive module preferably forms a supporting structure that supports all components of the drive module. Essentially, it is advantageously provided that all the components required for an electric drive are combined in the drive module. The drive module thus forms a compact unit that is only connected to a skateboard, in particular a deck of a skateboard, in order to equip the skateboard with an electric drive. The drive module can be operated using a remote control, in particular a wireless remote control. The remote control of the drive module can also be implemented by a mobile phone, in particular a smartphone, which contains appropriate software.

The frame can have several functions. On the one hand, the frame can guarantee protection of individual components of the drive module from damage. Furthermore, the frame, which delimits the receiving space for the energy store, can form a guide for the energy store, so that the energy store can be easily arranged in the drive module. Finally, the frame can form a heat sink, in particular if the frame is made of a metal, for example aluminum. This enables heat to be dissipated from components arranged within the frame, for example power electronics or the energy store. In addition, the frame has a function as a design element.

In a preferred embodiment of the drive module according to the invention, the frame comprises a base plate for the axle and can be detachably connected to a deck of the skateboard. The frame thus essentially combines all of the load-bearing components of the drive module, thereby providing a particularly compact unit. It can be provided that the frame, in particular the base plate, has a standardized hole pattern for connection to the deck.

As a rule, skateboards have a standardized hole pattern on their deck, which usually consists of six holes. The distances and the arrangement of the holes are essentially identical for all deck manufacturers, as a standard has been agreed here. Since the frame, in particular the base plate, in the drive module according to the invention preferably also has this hole pattern, the drive module can be attached to any deck for skateboards, regardless of a specific manufacturer. This increases the possibilities for using the drive module and makes it easier to mount the drive module on a skateboard.

The hole pattern can in particular have six holes or bores, two holes each forming a pair of holes. The distance between the two holes of each pair of holes is typically 41.3 mm (1.625 inches).

The pairs of holes are arranged in a row, the distance between the pairs of holes being different. In particular, a front pair of holes, a middle pair of holes and a rear pair of holes can be provided. The middle pair of holes is preferably at a greater distance than the rear pair of holes to the front pair of holes. The terms "front" and "rear" refer to the direction of travel of a skateboard with the mounted base plate. In particular, the rear pair of holes is arranged closer to the receiving space for the energy store than the middle and / or front pair of holes. The front pair of holes and the middle pair of holes can in particular be arranged in front of the axle and the rear pair of holes behind the axle.

The distance between the rear pair of holes and the middle pair of holes is preferably 54 mm (2.125 inches). The rear pair of holes can be 63.5 mm (2.5 inches) apart from the front pair of holes. The hole spacing of the holes of the front and rear pairs of holes is suitable for mounting the base plate or the drive module on a deck that has a so-called "old school" hole pattern. The hole spacing between the holes of the front and middle pair of holes is, however, suitable for mounting the base plate or the drive module on a deck that has a so-called "New School" hole pattern.

The frame can also have a support plate which can be connected to a deck of the skateboard independently and / or at a distance from the base plate. The support plate increases the stability of the drive module in the assembled state. The support plate can be adapted to the contour of the skateboard board or it can carry a damping layer that presses against the contour of the deck of the skateboard. The damping layer can for example consist of rubber or foam rubber.

For connection to the deck of a skateboard, the frame preferably has a form-fitting element, in particular a keyhole opening. The form-fit element is preferably formed in the support plate. The use of the form-fit element enables the drive module to be fastened in a particularly stable and simple manner to a deck of a skateboard. The form-fit element can serve to pre-fix the drive module. The user can connect the drive module to the deck with a form fit and then fix it with a screw connection through the hole pattern of the base plate. This facilitates assembly and at the same time ensures that the drive module is securely and safely attached to the skateboard deck.

In a preferred variant of the drive module it is provided that the frame forms at least one protective bracket which connects the support plate to the base plate. The support plate and the base plate can be arranged essentially at the same level. In the assembled state, both plates, the support plate and the base plate, are connected to a deck of the skateboard. The protective bar connects the support plate to the base plate, it being possible for the protective bar to be arranged at a distance from the deck of the skateboard. This makes it possible to use the protective bar as impact protection for other components of the drive module. In addition, the frame essentially forms a cage through the protective bracket, so that all components of the drive module are securely held within the frame.

The electric motor of the drive module can be connected to a controller which is arranged within the frame. The controller can preferably be electrically connected to the energy store. The controller can essentially comprise power electronics that regulate the power of the electric motor. The power electronics can be arranged on a uniform circuit board. By arranging the controller within the frame, the controller is protected by the frame.

The control can be arranged in a control housing, the frame, in particular the protective bracket, at least partially engaging around the control housing. Essentially, the frame can form a cage that extends around the control housing and thus protects the control housing from knocks, impacts or stone chips. The control housing itself can be made of plastic or a metal, in particular aluminum. When using a metal, the control housing serves on the one hand as an additional shock protection and on the other hand for heat dissipation. The control housing is preferably firmly connected to the frame.

In a preferred embodiment of the invention, the control housing has a plug contact for the electrical connection of the energy store to the control. The plug contact can be designed as a plug or socket. In any case, the plug contact is preferably designed such that an electrical connection between the controller and the energy store is made possible simply by pushing the energy store into a guide which is preferably formed in the receiving space for the energy store. The electrical connection between the energy storage and the control can be established with a single movement. The plug contact can be designed with multiple poles and include both power contacts and data contacts. The interface between the controller and the energy store preferably enables the transmission of data and an electrical connection to the power supply. The control includes, for example, the power electronics, battery management electronics and a wireless communication unit. The wireless communication unit enables wireless communication with a remote control, for example via Bluetooth, in particular Bluetooth LE, Zigbee or WLAN.

In a further, preferred embodiment of the invention it is provided that the frame and / or the control housing have a latching mechanism for fixing the exchangeable energy store. The latching mechanism enables the energy store to be exchanged quickly and easily. In particular, the energy store can be removed or inserted with a single movement. The energy store is connected sufficiently firmly to the drive module and at the same time an electrical connection is established with the controller. The energy storage device can be changed without tools.

The drive module is preferably designed such that it can remain in a mounted state on a deck of a skateboard while the energy store is being changed. Changing the energy store does not require dismantling of the entire drive module, but can take place with the drive module in the mounted state. This further facilitates the handling of the entire drive module.

To save weight it can be provided that the energy store has a housing made of plastic. Latching elements on the energy store, which interact with the latching mechanism on the frame and / or on the control housing, can be integrated into the plastic housing.

Furthermore, it can be provided that the axle has an axle support, a cable duct being formed in the axle support. The axle support is preferably articulated to the base plate. The axle beam is also used in technical jargon Called a hanger. The hanger is preferably connected in an articulated manner to the base plate of the frame so that the user can change the direction of travel while driving by shifting his weight. In order to provide the power supply for the electric motor, a cable connection between the controller and the electric motor is useful.

According to the invention it is provided that the electric motor is designed as a wheel hub motor. The electric motor is consequently seated directly on the axle or on an axle bolt of the axle. The electric motor can have an exchangeable running surface, so that the electric motor itself essentially forms the wheel of the drive module. The cable duct, which is formed in the hanger or in the axle support, serves to protect the cable connection between the electric motor and the controller.

The present invention also relates to a set with a drive module described above and a retaining bolt. The retaining bolt can on the one hand be firmly connectable to a deck of a skateboard. On the other hand, the retaining bolt can be connected to the frame of the drive module in a form-fitting, unlockable manner. The set thus includes all components to use the drive module on any skateboard deck. The user can easily retrofit an existing skateboard with an electric drive module. The connection to the deck of the already existing skateboard is made on the one hand via the standardized six-hole pattern with which the frame, in particular the base plate, of the drive module is fixed on the deck. In order to ensure sufficient stability, the set also contains the retaining bolt, which is firmly attached to the deck on the one hand and positively engages in the frame on the other hand in order to form another fixing point for the drive module. The retaining bolt can be screw-connected or glued to the deck of the skateboard.

The set can also have an exchangeable energy store, in particular an accumulator. The energy store is preferably adapted so that it is or can be arranged in the receiving space of the frame of the drive module.

Another aspect of the invention relates to a skateboard with a deck and a drive module described above. The drive module is preferably connected to the deck.

Fig. 1 shows the essential components of the drive module according to the invention in a preferred embodiment. The drive module 1 for a skateboard comprises a frame 10 which delimits a receiving space 11. An energy store 30 can be pushed into the receiving space 11. In the present exemplary embodiment, the energy store 30 is an accumulator or battery pack executed. Alternatively, the energy store 30 can also be designed as a battery. The frame 10 is connected to an axle 20 which carries two wheels 27. The connection between the axis 20 and the frame 10 is preferably articulated.

Also shows Fig. 1 a control 40, in particular a control housing 41. The control housing 41 is constructed from a housing body 44 which can be closed by a back plate 43. Power electronics 42 are preferably arranged within the control housing 41. The back plate 43 has a socket 45 which enables electrical contact between the controller 40 and the energy store 30.

The frame 10 has a base plate 12 and a support plate 13. The base plate 12 and the support plate 13 are connected by two protective brackets 15. Specifically, lateral side profiles 16 extend from the support plate 13 and merge into the protective bars 15. The side profiles 16 form a guide 14 for the energy store 30 so that it can be pushed into the frame 10. A frame neck 17, which is designed as a double-headed connecting profile, extends between the base plate 12 and the protective brackets 15. The protective brackets 15 essentially merge into the common frame neck 17.

As in particular in Fig. 6 can be clearly seen, the base plate 12 and the support plate 13 are arranged in a common plane. The frame neck 17 extends from this plane and connects the base plate 12 to the protective brackets 15, which are arranged at a distance from the common plane of the base plate 12 and the support plate 13. The protective bars 15 extend essentially parallel to this common plane. The frame neck 17 and the protective bars 15 essentially form a Y-profile when viewed from above.

In the assembled state, the controller 40, in particular the controller housing 41, is arranged within the frame 10. The control housing 41 is firmly connected to the frame 10. The control housing 41 extends below the protective bracket 15. In other words, the control housing 41 is encompassed by the protective bracket 15. The protective bars 15 thus form a shock protection for the control housing 41 or the control 40. At the same time, the side profiles 16 can at least Extend in sections over the control housing 41, so that a lateral impact protection for the control housing 41 is guaranteed.

The side profiles 16 are connected to one another by the support plate 13. A form-fit element 18, preferably in the form of a keyhole opening, is formed in the support plate 13. The form-fit element 18 is used to fix the drive module 1 on a deck 50 of a skateboard.

The in Fig. 1 The energy store 30 shown is essentially designed as an accumulator or battery. For this purpose, the energy store 30 has a battery housing 31 which is composed of two side parts 32 and a front plate 33. The side parts 32 and the front plate 33 are preferably made of plastic. The outer contour of the battery housing 31 essentially corresponds to the inner profile of the receiving space 11 in the frame 10, so that the battery housing 31 can be pushed into the receiving space 11, in particular along the guide 14, and fixed there in a form-fitting manner.

Fig. 2 shows the structure of the control 40 in detail. The control 40 essentially comprises the control housing 41 with the housing body 44 and the back plate 43. Power electronics 42 are arranged within the control housing 41. Furthermore, a radio communication unit 46 is provided in the illustrated embodiment. A socket 45 is formed in the back plate 43 for the electrical connection and for the data connection between the controller 40 and the energy store 30. The socket 45 is preferably designed so that an electrical connection between the controller 40 and the energy store 30 can be established by simply pushing the energy store 30 into the receiving space 11. Furthermore, the control housing 41, in particular the housing body 44, comprises a cable outlet 47, which enables the cable connection between the control 40 and an electric motor of the drive module 1. The cable outlet 47 is preferably arranged close to the axis.

In Fig. 3 the structure of the energy store 30 is shown in detail. The energy store 30 comprises the battery housing 31 with the side parts and the front plate 33. A plurality of cells, in particular battery cells or accumulator cells, are preferably arranged within the battery housing 31. Several cells 36 are interconnected to form cell blocks 37. The cell blocks 37 are electrically connected to a connector 35 which is arranged on the rear plate 43. The plug 35 is preferably oriented in such a way that when the energy store 30 is pushed into the receiving space 11 it engages in the socket 45 of the controller 40 and thus establishes an electrical connection. Battery management electronics 34 are also arranged in battery housing 31. The battery management electronics 34 control the charging and discharging process of the energy store 30. In addition, the battery management electronics 34 provide a signal connection to the power electronics 42 of the controller 40 so that status data of the energy store 30 can be called up via the power electronics 42. In addition, the data connection between the battery management electronics 34 and the controller 40 can be transmitted by the radio communication unit 46 to a display device that can be radio-connected to the drive module 1, for example a remote control and / or a smartphone.

The Figures 4 and 5 show an axle 20 of the drive module 1. The axle 20 comprises an axle carrier 21, which in technical jargon is also called a hanger. Axle bolts 22 are integrally formed on the axle support 21. The geometry of the axle 20 essentially corresponds to the geometry of known skateboard axles. The axle support 21 has a cable duct 23, which extends essentially from the axle bolt 22 to close to an articulated connection between the axle support and the base plate 12. The articulated connection itself is for the sake of clarity in the Figures 4 and 5 not shown.

A cable 28 is arranged in the cable duct 23 and extends from an electric motor along the cable duct 23 to the frame neck 17. For this purpose, a cable bushing 19 is formed in the frame neck 17 so that the cable 28 is routed to the control 40 in a largely protected manner. Because of the cable duct 23, the distance that the cable 28 covers unprotected is reduced to a minimum. A duct cover 24, which can be snap-connected to the axle support 21, is also used for this purpose. The axle support 21 has recesses 26 in which locking elements 25 are arranged. Corresponding latching elements 25 are also arranged in the cable cover 24, so that the cable cover 24 can be inserted into the recess 26. The depth of the recess 26 is preferably adapted to the wall thickness of the cable cover 24.

As in the Figures 4 and 5 is indicated, the axle support 21 preferably has a cable duct 23 on both sides, which leads to one of the axle bolts 22 of the axle 20. Correspondingly, two recesses 26 and two channel covers 24 are provided. The drive module 1 is preferably equipped with two electric motors, which are designed as wheel hub motors. The axle bolts 22 therefore each directly carry an electric motor, the electric motor having an outer running surface. The electric motor essentially serves as a wheel 27 of the drive module 1. The electric motors can preferably be controlled separately, thereby achieving a high degree of flexibility in different driving situations.

In the Figures 6 and 7 the connection of the drive module to a deck 50 of a skateboard is shown as an example. Essentially, the frame 10 of the drive module 1 serves as a connecting link between the drive module 1 and the deck 50. For this purpose, on the one hand, the standardized hole pattern in the deck 50 is used, which usually comprises six holes. The base plate 32 comprises a corresponding number of bores, in particular at least four bores, so that the frame 10 on the base plate 12 can be connected to the deck 50 by screws 54. In order to stabilize the connection, the form-fit element 18 is preferably also formed on the frame 10, the form-fit element 18 being arranged at a distance from the base plate 12. The form-fit element 18 is preferably formed by a keyhole opening which is formed in the support plate 13.

In conventional decks 50 for skateboards, no corresponding counter-element is usually provided in place of the form-fit element 18. In this respect, it is advantageous to offer the connection module 1 in a set with a retaining bolt 51, the retaining bolt being connectable to the deck 50. The retaining bolt can be connected to the deck 50 by a screw connection or, as in the illustrated embodiment, by an adhesive connection.

For a sufficient adhesive connection, the retaining bolt 51 preferably has an adhesive plate 52 which provides an enlarged adhesive surface. The size of the adhesive plate 52 is dimensioned such that a sufficiently strong connection between the retaining bolt 51 and the deck 50 is ensured. To connect the retaining bolt 51 to the frame 10, the form-fitting element 18 in the form of the keyhole opening, which is shown in FIG Fig. 7 is easily recognizable. To a To ensure a positive connection not only in the horizontal but also in the vertical direction, the retaining bolt 51 has a bolt head 53 which, in the assembled state, engages behind the positive connection element 18 or an elongated hole section of the keyhole opening.

The drive module 1 preferably together with an energy store 30 has a mass of less than 4 kg, in particular less than 3 kg. Furthermore, it is preferably provided that the entire drive module 1 including the energy store 30 is designed to be essentially liquid-tight. To this end, it can be provided in particular that a seal is arranged between the energy store 30 and the controller 40. The seal is preferably formed firmly on the back plate 43 of the control housing 41.

The entire drive module 1, in particular including the energy store 30, is preferably designed so that speeds that are greater than 20 km / h can be achieved with it. With regard to the wheels 27 designed as a wheel hub motor, it is preferably provided that these have an outer diameter of at most 80 mm. The wheels 27 can be driven by the electric motor in the form of an electric direct drive. The electric motor and the controller 40, in particular the power electronics 42, can be designed in such a way that the electric motor is effective as a recuperation brake.

With regard to the energy store 30, it is preferably provided that it is formed by an accumulator or accumulator which has an integrated battery management system. The accumulator preferably has an energy content of approximately 100 Wh. The drive module 1 can be operated with a direct current voltage of 24 volts nominal. The accumulator can include two cell blocks 37 with a total of 14 cells. The cells 36 are preferably designed as lithium-ion cells.

Furthermore, it can be provided that the energy store 30, in particular the battery housing 31, includes a display that provides information about the charge status of the cells 36. The display can for example be formed by a row of LEDs. The charge status query can be triggered by pressing a button, a corresponding actuating button being provided on the battery housing 31. The battery management electronics 34 are preferably so with the display coupled that a charge status display is also possible when the energy store 30 is decoupled from the controller 40. Furthermore, the energy store 30, in particular the battery management electronics 34, is preferably designed in such a way that the cells 36 can be charged both in the installed state within the drive module 1 and independently of the drive module 1.
