Description

[0001] Electrically driven tilting vehicle

[0002] The invention relates to an electrically driven tilting vehicle.

[0003] Electrically powered tilting vehicles are known from the prior art, which feature an electrical energy storage unit that supplies an electric drive with electrical energy. The electrical energy storage units comprise a storage housing that forms a closed unit.

[0004] Embodiments of electrically driven tilting vehicles are known in which the storage housings form a frame support structure of the tilting vehicle. These known storage housings involve a split between the housing halves in the main flow of the driving dynamics loads. As a result, the connection between the steering and the rear wheel guide, which is essential for driving dynamics, exhibits an inadequate stiffness profile.

[0005] In addition, the accessibility of energy storage units arranged in the storage housing is often not possible or only possible by completely dismantling the storage housing from the outside.

[0006] An object of an embodiment of the invention is to propose an electrically driven tilting vehicle whose suitability for use as an element of the frame support structure is improved.

[0007] This object is achieved by an electrically driven tilting vehicle with at least one frame support structure to which at least one electric drive means, at least one front wheel guide, at least one spring strut and / or at least one swing arm unit of a rear wheel can be fixed, and with at least one electrical energy storage unit, which comprises at least one storage housing that completely encloses a cavity to the outside, and at least one electrical storage means that can be arranged or is arranged in the cavity and by means of which at least the drive means can be supplied with electrical energy, wherein the storage housing comprises at least one load-bearing frame body that has a cross-section in a plane spanned by the vertical axis and the longitudinal axis of the tilting vehicle,with which the frame body completely encloses the cavity on the circumference and wherein the load-bearing frame body of the storage housing of the energy storage unit and the frame support structure form a common one-piece component at least in sections.

[0008] Because the electrically driven tilting vehicle comprises an energy storage unit with a storage housing, which includes a load-bearing frame body. The frame body has a cross-section on a plane spanned by the vertical and longitudinal axes of the tilting vehicle, with which the frame body completely encloses the cavity on its circumference, a supporting ring is formed through which a force can be absorbed and transmitted. This allows the main force flow to be absorbed and transmitted. Furthermore, the formation of an undivided frame body improves the rigidity profile.

[0009] Because the frame body completely encloses the cavity on its periphery, the frame body extends around the cavity in a ring-like or frame-like manner. Because the frame body encompasses the closed cross-section in the plane through the vertical and longitudinal axes of the tilting vehicle, the frame body can accommodate and transmit loads parallel or obliquely to the vertical and / or longitudinal axes of the tilting vehicle.

[0010] A tilting vehicle is understood to mean bicycles, motorcycles or motorcycle-like motor vehicles, such as scooters, in particular two-, three- or four-wheeled scooters, tilting trikes, quads or the like.

[0011] In a further development of the tilting vehicle, it is provided that the frame support structure comprises at least one steering head receptacle which comprises at least one continuous hollow cylindrical recess in which the front wheel guide can be or is rotatably mounted and fixed, wherein the steering head receptacle comprises a separate or separable component which can be fixed to the frame body or wherein the steering head receptacle comprises a section of the frame body and the steering head receptacle and frame body form a common one-piece component.

[0012] The steering head mount allows the front wheel guide to be pivotally mounted on the frame support structure. If the steering head mount comprises a separate or separable component, it can be removably or permanently mounted on an outer surface of the frame body.

[0013] If the steering head mount and the frame body form a single, integral component, the assembly effort for the tilting vehicle is reduced.

[0014] Furthermore, in a further development of the tilting vehicle, it is provided that the frame support structure, in particular on the side of the frame body opposite the steering head receptacle, comprises a receptacle for the spring strut and / or the swing arm unit of the tilting vehicle, wherein the receptacle for the spring strut and / or the swing arm unit comprises a separate or separable component that can be fixed to the frame body or wherein the receptacle for the spring strut and / or the swing arm unit comprises a section of the frame body and the receptacle for the spring strut and / or the swing arm unit and the frame body form a common one-piece component.

[0015] If the mount for the shock absorber and / or the oscillating unit comprises a separate or separable component, this can be fixed to an outer surface of the frame body.

[0016] If the mount for the suspension strut and / or the swing arm unit and the frame body form a single, integral component, the tilting vehicle can be easily pre-assembled.

[0017] If the frame body and the steering head mount as well as the mount for the shock absorber and the swing arm unit form a common one-piece component, this can be manufactured, for example, in the manufacturing process, for example in the casting process and / or the injection molding process.

[0018] This makes it possible to reduce the number of individual work steps required to manufacture the tilting vehicle.

[0019] Furthermore, in a further development of the tilting vehicle, it proves to be advantageous if the frame support structure comprises a drive mount for the drive means of the tilting vehicle, wherein the drive mount comprises a separate or separable component that can be fixed to the frame body or wherein the drive mount comprises a section of the frame body and the drive mount and frame body form a common one-piece component.

[0020] In order to increase the rigidity of the frame body, it is advantageous if the frame body comprises at least one, in particular rib-like, reinforcing means which extends parallel or obliquely to the plane spanned by the vertical axis and the longitudinal axis of the tilting vehicle and which is arranged on a surface of the frame body facing or facing away from the cavity.

[0021] In this case, the frame body can comprise a single rib-like reinforcement element, which extends, for example, from the area of ​​the steering head mount to the mount of the suspension strut and / or the swing arm unit or the drive mount. Furthermore, several reinforcement elements running parallel or diagonally to one another can be provided.

[0022] In order to be able to arrange at least one electrical energy storage unit in the cavity of the storage housing or to maintain or replace it as required, it proves to be advantageous if the frame body comprises at least one opening through which the cavity is accessible from a direction oblique or parallel to the transverse axis and if the storage housing comprises at least one cover element, wherein at least one of the at least one cover element is detachably fixable to the frame body, in particular by means of force, friction and / or form fit, or non-detachably fixable, in particular by means of force, friction, material or form fit, and covers at least one of the at least one opening in sections or in its entirety.

[0023] Because the frame body comprises at least one opening through which the cavity is accessible from a direction oblique or parallel to the transverse axis of the tilting vehicle, the at least one electrical energy storage unit can be easily arranged in the cavity. The frame body can, for example, be pot-shaped and encompass the opening on only one side and a closed surface on the side opposite the opening.

[0024] Furthermore, embodiments of the frame body are conceivable in which the opening is continuous, i.e., extending from one side of the frame body through the cavity to the other side of the frame body. In this case, the frame body is accessible from both sides.

[0025] If at least one of the at least one cover element can be releasably secured to the frame, the cavity can be closed after the at least one energy storage unit has been arranged. This makes it possible to design the storage housing such that the cavity is entirely enclosed by the frame body and the at least one cover element.

[0026] In order to reduce the risk of dirt or moisture penetrating the cavity, a further development of the latter embodiment provides that the storage housing comprises at least one sealing means which can be arranged or is arranged between the cover element and the frame body.

[0027] The sealing means is particularly designed to be continuous and completely closes any gap that may exist between the cover element and the frame body.

[0028] In order to facilitate the arrangement of the at least one electrical storage means, in particular in order to be able to ensure the arrangement of a plurality of electrical storage means in the cavity in a simple manner, one embodiment of the tilting vehicle provides that the storage housing has at least one planar floor element which is arranged in the cavity and is rotatably or non-rotatably fixed to the frame body and on which at least one electrical storage means can be arranged and fixed.

[0029] In such a case, the at least one storage means can be stacked on the at least one planar floor element. The planar floor element can comprise a plane or a surface structure or coating that increases the friction between the floor element and the storage means.

[0030] Furthermore, embodiments of the tilting vehicle are conceivable in which several floor elements are provided which are arranged parallel or obliquely to one another and spaced apart from one another in the cavity.

[0031] The planar floor element can be fixed to the frame body in a rotationally fixed manner. In this case, deformations, particularly force transmission, from the frame body to the floor element are conceivable. If the floor element is rotatably fixed to the frame body, the floor element can be decoupled from the frame body with respect to force flow.

[0032] In a further development of the latter embodiment, it proves to be advantageous if at least one of the at least one floor element fixed to the frame body forms a load-absorbing stiffening means by which forces acting on the frame body can be absorbed and transmitted.

[0033] This proves particularly advantageous when at least one base element is fixed to the frame body in a rotationally fixed manner, thus enabling a flow of force from the frame body into the base element. This increases the rigidity of the storage housing.

[0034] Finally, it proves to be advantageous if the frame body, the reinforcing means, the base element and / or the cover element comprise, in whole or at least in part, a plastic, in particular a carbon fiber reinforced plastic, in particular a carbon fiber composite plastic - titanium and / or carbon fiber composite plastic - aluminum hybrid structure, and / or a polyaramid, in particular Kevlar.

The front wheel guide 6 is rotatably mounted to the frame support structure 4 via the steering head mount 26.

[0043] In addition, the frame support structure 4 comprises, on the side of the frame body 20 opposite the steering head receptacle 26, a receptacle 28 for the spring strut 8 and / or for the swing arm unit 10 of the tilting vehicle 2. The receptacle 28 is also designed as a separable component and is fixed to the frame body 20.

[0044] Looking at Figures 2 and 3, it can be seen that the storage housing 16 comprises a plurality of rib-like reinforcing means 30 which extend parallel or obliquely to the plane spanned by the vertical axis 22 and the longitudinal axis 24 of the tilting vehicle 2 and are arranged on a side of the frame body 20 facing away from the cavity 18.

[0045] In the embodiment shown in the figures, the frame body 20 is designed such that it is accessible from the outside via two openings 32. Looking at Figure 2, it can be seen that the cavity 18 is accessible through the opening 32 parallel or obliquely to a transverse axis 34 of the tilting vehicle 2.

[0046] In order to completely surround the cavity 18, the storage housing 16 in the embodiment shown in the figures comprises two cover elements 36 that can be releasably secured to the frame body 20. The cover elements 36 completely cover the openings 32.

[0047] Furthermore, in the embodiment shown in Figure 2, three base elements 38 are arranged in the storage housing 16, which are rotatably attached to the frame body 20. Storage means can be arranged on the base elements 38.
