Description

[0001] The present invention relates to a motor vehicle with a cable winch that can be driven by a first electric motor, according to the preamble of claim 1.

[0002] From US 9 446 701 B2, a generic motor vehicle is known with a cable winch that can be driven by a first electric motor, whereby objects and / or persons are to be moved comfortably into and out of the motor vehicle via the cable winch, for example via a corresponding ramp.

[0003] DE 10 2006 016 496 A1 discloses a lifting and loading device, particularly for use in a motor vehicle, comprising a detachably mountable support rail with at least two holding devices, a trolley running on or in the support rail, a lifting device, and a drive device for the lifting device. This is intended, in particular, to create a system that can be used independently of the vehicle.

[0004] DE 20 2021 003 535 U1 discloses a mobile loading device for transporting wheelchairs and other loads over an obstacle, such as a loading edge, into the cargo area of ​​a motor vehicle. Individual support beams of this lifting device are designed as folding supports.

[0005] DE 10 2017 201014 A1 and DE 10 2021 202 092 A1 disclose a motor vehicle with a cable winch driven by a first electric motor. The electric motor can drive another component, such as a pump or an agricultural implement, via the power take-off.

[0006] DE 10 2011 080 633 A1 discloses a motor vehicle with a cable winch that can be driven by a first electric motor and a further component.

[0007] In motor vehicles, such as vans or station wagons, it is often very difficult to load and unload heavy objects, such as lawnmowers or even people in wheelchairs. Depending on the weight, this may be impossible or difficult without a cable winch. If a cable winch is available, the high torque of electric motors can make this task easier and increase the versatility of the vehicle.

[0008] The disadvantage, however, is that the effort required to install such a cable winch is often comparatively complex and therefore expensive, as both the cable winch and a corresponding bracket or a special bumper are required.

[0009] The present invention therefore addresses the problem of providing an improved or at least an alternative embodiment for a motor vehicle of the generic type, by means of which in particular the disadvantages known from the prior art can be overcome.

[0010] This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0011] The present invention is based on the general idea of ​​using a first electric motor in a motor vehicle not only to drive a cable winch, but also to drive or adjust at least one other component. Electric motors are now installed in large numbers in motor vehicles, with cable winches, for example, being used primarily in emergency vehicles, such as those used by fire departments, technical relief organizations, or in the forestry sector. As already mentioned at the beginning, cable winches usually have a separate electric motor that, together with the cable winch, is permanently attached to the vehicle and can wind up or unwind a cable via a drum.The motor vehicle according to the invention now implements for the first time the idea of ​​using an electric motor already used in a motor vehicle, for example, an electric motor for adjusting a motor vehicle seat, to simultaneously drive the cable winch, or vice versa. This makes it possible for the first time to assign an additional function, in particular an additional drive function, to a first electric motor for driving a cable winch, thereby eliminating the need for a further electric motor, for example, a separate electric motor, for adjusting a motor vehicle seat, in particular a backrest of the motor vehicle seat.In general, the motor vehicle according to the invention not only reduces the variety of parts and the associated manufacturing effort and costs, but also offers space advantages because, unlike previously, two separate electric motors do not have to be provided to drive the cable winch and the at least one other component. Thus, the motor vehicle according to the invention makes it possible, for example by means of a ramp positioned against a loading edge, to pull objects, such as loads placed on trolleys, into the cargo area using the cable winch, thereby loading the vehicle extremely conveniently. Furthermore, the cable winch can be used to relatively easily transport a wheelchair user or a wheelchair into the vehicle and simultaneously unload it safely from the vehicle.If the cable winch is not required, a cable winch drive can be decoupled from the first electric motor using a corresponding coupling / switching device, and the latter can only be used to adjust or drive the other component.

[0012] In an advantageous development of the motor vehicle according to the invention, the at least one further component is at least a part of a motor vehicle seat, for example a backrest of such a motor vehicle seat. Modern motor vehicles, in particular in the premium segment, usually have a large number of electric motors in the area of ​​seat adjustment, one of which can now also be used according to the invention to drive the cable winch. The advantage here is that such an electric motor is already firmly anchored to the motor vehicle, so that a space-optimized and parts-reduced solution can be offered by also firmly anchoring the cable winch, for example also under the motor vehicle seat.which is carried out by at least one further component, for example via a worm drive, a self-locking gear is arranged between the first electric motor and the cable winch, which is of great advantage, particularly in the case of cable winches.

[0013] In a further advantageous embodiment of the solution according to the invention, the electric motor has an adjustable shaft which, in a first position, is connected to the cable winch and, in a second position, to the at least one further component, in particular the motor vehicle seat. The adjustable shaft represents a type of clutch / switching device by means of which an alternative drive of either the cable winch or the further component can be selected by means of the first electric motor. Such a clutch / switching device can be controlled, for example, by means of a motor controller, whereby switching between the drive of the cable winch and the drive of the further component is comparatively easy.

[0014] In a particularly preferred embodiment of the motor vehicle according to the invention, a motor control is provided for controlling the cable winch, wherein a cable force, a cable path, and / or a cable pulling speed can be adjusted and / or limited via the motor control. This makes it possible, for example, to limit a cable force such that the object to be pulled or the motor vehicle is not damaged. The cable pulling speed can also be influenced via the motor control, thereby enabling objects to be pulled into a cargo area of ​​the motor vehicle more quickly or, if necessary, more slowly.

[0015] It is advisable to provide at least one pulley that can be connected to the motor vehicle and used to redirect a cable of the cable winch. Such a pulley can be attached, for example, via a corresponding carabiner to different locations on the motor vehicle, in particular to different locations in the cargo area, thus allowing for different cable routing. This prevents, in particular, the cable from rubbing against vehicle parts when the cable winch is in use, thus preventing damage to the motor vehicle and / or the cable.

[0016] In a further advantageous embodiment of the motor vehicle according to the invention, a ramp, in particular a removable one, is provided, which forms a path into a cargo space of the motor vehicle. Such a removable ramp can be realized, for example, using corresponding aluminum sheets, which, in a use position, are suspended on the one hand, for example, from a loading edge of the motor vehicle and, on the other hand, rest on a floor. This makes it relatively easy to create a path for a wheelchair user into a cargo space of the motor vehicle, for example. The ramp can either be manually removable or, alternatively, can be automatically extended and retracted.

[0017] In a particularly preferred embodiment of the motor vehicle according to the invention, a second electric motor is provided for adjusting another motor vehicle seat, which second electric motor can be drivably connected to the first electric motor and thus to the cable winch. The first electric motor with the cable winch can be used, for example, to adjust a driver's seat, while the second electric motor can be used to adjust a passenger seat. In order to increase the pulling force of the cable winch, it is conceivable to couple the second electric motor to the first electric motor and then to the cable winch, so that both the driving force of the first electric motor and the driving force of the second electric motor can be used to pull particularly heavy loads using the cable winch.

[0018] The motor vehicle is expediently designed as an electric vehicle or a hybrid vehicle. Electric vehicles are increasingly being used, particularly in inner-city traffic, to keep environmental pollution as low as possible. These vehicles have the advantage that their large battery can deliver significant electrical output in the form of current or voltage over a period of time, even without the engine running. Electric vehicles are also used, in particular, for transporting wheelchair users, so the inventive design of the motor vehicle with a vehicle seat adjustable by means of the first electric motor and a cable winch driven by the vehicle seat offers significant advantages.

[0019] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures with reference to the drawings.

[0020] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the present invention. Components mentioned above and to be mentioned below of a higher-level unit, such as a device, an apparatus, or an arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0021] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0022] They show, schematically: Fig. 1 a sectional view through a motor vehicle according to the invention, Fig. 2 a plan view of a motor vehicle according to the invention, Fig. 3 shows a further representation of a motor vehicle according to the invention, Fig. 4a shows a detailed view of a motor vehicle according to the invention according to a further embodiment with an electric motor with an adjustable shaft in a second position, Fig. 4b a representation as in Fig. 4a, but with an electric motor with an adjustable shaft in a first position.

[0023] According to the Fig. 1-4, a motor vehicle 1 according to the invention has a cable winch 3 drivable by a first electric motor 2. The electric motor 2 is designed to drive and / or adjust at least one further component 4, for example, a motor vehicle seat 5. The cable winch 3 is equipped with a cable 6 that can pull an object 8, for example, a wheelchair, via a hook 7, for example. In the motor vehicle 1 according to the invention, it is thus possible to use the first electric motor 2 not only to drive the cable winch 3, but alternatively also to drive or adjust a further component 4, namely here the motor vehicle seat 5 or its backrest 9.

[0024] The first electric motor 2 can have an adjustable shaft 10 (compare the Fig. 4a and Fig. 4b) which in a first position are connected to the cable winch 3 (compare Fig. 4b) and in a second position (compare Fig. 4a) is coupled to the at least one further component 4, here the motor vehicle seat 5. In order to be able to further amplify the tensile force of the cable winch 3, it can also be provided to driveably connect a second electric motor for adjusting another motor vehicle seat 5, for example a passenger seat, to the first electric motor 2 and the cable winch 3, so that the power of both electric motors can be used to apply the tensile force.

[0025] A motor control 11 can be provided to control the cable winch 3, wherein a cable force, a cable path, and / or a cable pulling speed can be adjusted and / or limited via this motor control 11. This can reliably prevent, in particular, damage to the motor vehicle 1.

[0026] In order to enable the most flexible use of the cable winch 3, at least one deflection pulley 12 can be provided which can be connected to the motor vehicle 1 and via which the cable 6 of the cable winch 3 can be deflected. This also makes it possible to pull objects 8 located laterally next to the motor vehicle 1, as is shown in FIG. Fig. 1 is shown.

[0027] In order to further simplify loading of the objects 8 into a loading space of the motor vehicle 1, a, in particular removable, ramp 13 (cf. Fig. 3) may be provided, which, in its state of use, forms or enables a path into the cargo space of the motor vehicle 1. The motor vehicle 1 may generally be designed as an electric vehicle, but alternatively also as a hybrid or as a motor vehicle powered by an internal combustion engine.

[0028] The motor vehicle 1 according to the invention can be assigned significantly increased functionality without requiring a separate electric motor for the cable winch 3, with the associated separate cabling effort. Rather, the invention utilizes a first electric motor 2 already present in the motor vehicle 1 for adjusting a vehicle seat 5, in order to assign it an additional function. This increases the comfort and versatility of the motor vehicle 1 and, in particular, offers a solution for transporting wheelchairs.

[0029] In addition, such a motor vehicle 1 can also enable further auxiliary activities.
