Description

FIELD OF THE INVENTION

[0001] The present invention relates to a drive for a movable closure component of a vehicle. The present invention particularly concerns a drive device for a movable closure component for a vehicle, a drive device kit for a movable closure component for a vehicle, a movement module for a movable closure component for a vehicle, a motor vehicle door module, and a method for assembling a drive device. BACKGROUND OF THE INVENTION

[0002] In addition to manual operation, movable closing components of a vehicle, such as vehicle doors, also use drives, for example to raise or lower them. For example, door stays, also known as push-out units, are used in vehicle doors or body areas to open the vehicle door wide enough for the user to reach behind it with their hand. Another example is closing aids, in which a drive acts on a rotary latch to push the door shut. Users are increasingly demanding these additional functions, even in medium and small cars. However, it has been shown that these additional measures can conflict with the desire for the most economical vehicles possible. SUMMARY OF THE INVENTION

[0003] An object of the present invention is therefore to provide a simplified and as inexpensive as possible solution for driving a movable end component of a vehicle.

[0004] This problem is solved by the subject matter of the independent claims. Further examples are given in the dependent claims.

[0005] It should be noted that the features of the embodiments of the drive device of a movable closure component for a vehicle also apply to embodiments of the drive device kit for a movable closure component for a vehicle, the movement module of a movable closure component for a vehicle, the motor vehicle door module, and the method for assembling a drive device, and vice versa. Furthermore, those features can also be freely combined with one another where this is not explicitly mentioned.

[0006] According to the invention, a drive device for a movable closure component for a vehicle is provided. The drive device comprises an electric motor, a transmission device, and an actuating device. The transmission device is operatively connected to the electric motor, and the transmission device is operatively connected to the actuating device in order to transmit a drive force generated by the motor in a drive direction to the actuating device. The actuating device comprises a spindle and an actuating component. The spindle is rotatably driven by the transmission device and, upon rotation, moves the actuating component linearly between an initial position and an actuating position. The actuating component is a Bowden cable fastening for forming a door closing unit.The Bowden cable fastening is a tab provided on a spindle nut to which a Bowden cable can be fastened, whereby the spindle nut can be driven linearly by a rotary movement of the spindle in order to exert a tensile force on a Bowden cable.

[0007] The advantage is a drive device that can be used as an actuator for a closing aid, for example, and can rely on components and proven designs that are otherwise used for door openers. The spindle drive allows for a compact design while simultaneously offering the possibility of providing a relatively high drive force.

[0008] According to one example, the spindle is connected to a worm gear, which is drivable by a worm that is rotationally driven by the electric motor. The spindle nut is positioned closer to the worm gear in the initial position than in the actuated position.

[0009] According to one example, the spindle nut of the Bowden cable fastening has a width that is at least a quarter of the length of the spindle.

[0010] According to one example, the spindle nut is guided in a housing, and the housing has a widened portion to guide the tab. The Bowden cable pulls on the tab in a direction parallel to the spindle's longitudinal axis.

[0011] According to one example, the housing has a cylindrical basic shape. A lateral slot is formed to allow movement of the tab.

[0012] According to one example, the housing has a receptacle for supporting a sheath of a Bowden cable.

[0013] According to one example, a cover for a movement path of the tab is provided on the housing. The receptacle for supporting the housing of the Bowden cable is formed on one end face of the cover.

[0014] According to one example, the cover is detachably attached to the housing in order to be able to attach and detach the Bowden cable.

[0015] According to one example, the bracket protrudes from the spindle nut by a certain projection. The bracket has a length in the direction of movement that is at least half the projection.

[0016] According to the invention, a drive device kit for a movable closure component for a vehicle is also provided. The drive device kit comprises an electric motor, a transmission device, and an actuating device. The transmission device is operatively connected to the electric motor, and the transmission device is operatively connected to the actuating device to transmit a drive force generated by the motor in a drive direction to the actuating device. The actuating device comprises a spindle and an actuating component. The spindle is rotatably driven by the transmission device. Upon rotation, the spindle moves the actuating component linearly between an initial position and an actuating position. The actuating component is selectable from the group comprising i) a plunger for forming a door opening unit and ii) a Bowden cable attachment for forming a door closing unit.

[0017] This results in a cost reduction and thus enables a cost-effective solution for driving a movable end component of a vehicle. Using a drive device kit also simplifies assembly and maintenance.

[0018] According to one example, a housing is provided that has a base housing part and a connection housing part. The transmission device and the electric motor are arranged in the base housing part, and the actuating component is movably held in the connection housing part.

[0019] According to one example, the plunger has a spindle nut and is movably held in a first type of connection housing part. The Bowden cable fastening forms a spindle nut and is movably held in a second type of connection housing part. The base housing part and the connection housing part of the first type of connection housing part or the second type of connection housing part are connectable to one another for an assembled state of the drive device to optionally form a drive device for a door opening unit or a drive device for a door closing unit.

[0020] According to one example, the drive direction of the motor has the same direction for extending the plunger to open the vehicle door and for pulling the Bowden cable to close the vehicle door.

[0021] According to one example, the actuating device acts in a first force direction for the door opening unit and in a second force direction for the door closing unit. The first force direction is aligned with the second force direction.

[0022] According to one example, the spindle is arranged in the connector housing part; the first connector housing part type and the second connector housing part type are interchangeably attachable to the base housing part.

[0023] According to one example, the spindle nut of the tappet has a first pitch, and the spindle nut of the Bowden cable attachment has a second pitch that is smaller than the first pitch. The spindle of the actuating device is interchangeably mounted on the transmission device, and a first spindle matching the first pitch and a second spindle matching the second pitch are selectable.

[0024] According to the invention, a movement module of a movable closure component for a vehicle is also provided. The movement module comprises a drive device according to one of the preceding examples or a drive device kit according to one of the preceding examples, as well as a movement device. The movement device is designed to act on a movable closure component of a vehicle in order to move the closure component relative to a door frame structure. The movement device is movable by the actuating component.

[0025] According to one example, in a first option, the movement module is designed as a door-opening unit, and the movement device is the plunger of the actuating device, with which a relative force can be applied between the closing component and the door frame structure. According to a second option, the movement module is designed as a door closing unit, and the movement device is a component acting on a rotary latch, which can be actuated via a Bowden cable attached to the Bowden cable attachment of the actuating device in order to apply a relative force between the closing component and the door frame structure.

[0026] According to the invention, a motor vehicle door module is also provided, which comprises a support structure of a motor vehicle door and at least one movement module according to one of the preceding examples. The at least one movement module is mounted on the support structure.

[0027] According to the invention, a method for assembling a drive device is also provided. The method comprises the following steps: a) Providing an electric motor, a transmission device, an actuating device, a base housing part, and at least two connection housing parts; the transmission device is operatively connected to the electric motor in order to transmit a drive force generated by the motor in a drive direction to the actuating device; and the transmission device and the electric motor are arranged in the base housing part; the actuating device has a spindle and an actuating component; the spindle is rotatably driven by the transmission device; and the spindle, when rotated, moves the actuating component linearly between an initial position and an actuating position; the actuating component is movably held in the connection housing part;In a first connecting housing part, the actuating component has a plunger for forming a door opening unit, wherein the plunger has a spindle nut and is movably held in a first connecting housing part type; and in a second connecting housing part, the actuating component has a Bowden cable fastening for forming a door closing unit, wherein the Bowden cable fastening forms a spindle nut and is movably held in a second connecting housing part type; b) selecting the first connection housing part type or the second connection housing part type to selectively form a drive device for a door opening unit or a drive device for a door closing unit; and c) Connecting the selected terminal housing part to the base housing part for an assembled state of the drive device.

[0028] According to one aspect, a kit for a drive device is provided that allows two different drive devices to be designed using the highest possible proportion of identical parts. The drive, i.e., the motor and at least part of the transmission for transmitting the power from the motor to the actuating device, is formed by a type of base. The other part is at least partially interchangeable, depending on its function. According to one aspect, a bifunctional kit is provided.

[0029] According to one aspect, the same spindle drive is used for a closing aid and a door stay. Only the plunger or the Bowden cable attachment can be interchanged to accommodate both functions. The direction of force is the same, so the drive and gear can be designed for more or less the same load case.

[0030] The proposed drive, for example, provides the ability to execute a specific stroke with a specific force for both closing aids and push-out units. Connecting the Bowden cable to the spindle nut, instead of attaching the closing Bowden cable to the spindle, simplifies the connection and routing of the Bowden cable. The drive with the same spindle can also be used for a push-out solution, where, for example, the drive direction of the motor and the spindle can be the same.

[0031] In one example, the Bowden cable is retrofitted from the outside. In another example, the motor is arranged parallel to the worm gear. One option, for example, includes Evoloid gearing.

[0032] Providing identical parts for the closing aid and push-out unit offers not only cost advantages but also economies of scale. Using a spindle with a spindle nut also allows for a more compact drive. Both actuators, i.e., the closing aid and the push-out unit, can also be manufactured on the same assembly / production line. Common parts are particularly common in the gearing. BRIEF DESCRIPTION OF THE DRAWINGS

Motor vehicle doors can, for example, be doors that swing open to the side, or sliding doors or even doors or door segments that swing open upwards.Motor vehicle flaps can be, for example, tailgates. Motor vehicle hoods can be, for example, engine compartment hoods, for example in the front area of ​​the vehicle. Motor vehicle hoods can also be front hoods for closing off storage areas underneath. These front hoods are also referred to as frunks (from the English: front trunk). Loading flaps can be, for example, pivoting flaps provided at the rear or on the side to allow access to a loading area or a loading area. The loading flaps can also be referred to as motor vehicle loading flaps. In connection with so-called pick-up trucks, e.g. with an open loading area, the loading flaps are also referred to as drop gates. When motor vehicle doors are mentioned in the context of the present invention, this also includes the other forms of the movable closing component mentioned as examples.The term door lock includes, for example, a lock for a motor vehicle door, a lock for a motor vehicle hatch, a lock for a motor vehicle hood or a lock for a tailgate.

[0046] The term “locking device” refers, for example, to mechanical assemblies for locking or moving a movable vehicle component.

[0054] Fig. 2 shows another example of the drive device 10 of a movable closure component for a vehicle in a sectional view.

[0055] In the option in Fig. In the example shown in Figures 2 et seq., the spindle nut 24 is guided in a housing 42. The housing 42 has a widened portion 44 for guiding the tab 26. The Bowden cable 28 pulls on the tab 26 in a direction parallel to the longitudinal axis of the spindle 18.

[0060] In the example shown as an option, it is provided that the tab 26 protrudes from the spindle nut 24 with a projection dimension 56, whereby the tab 26 has a tab length 58 in the direction of movement (see also the width 38 in Fig. 1) which is at least half the projection dimension 56.

[0061] The term "overhang dimension" refers to the length of the overhang, i.e., how far the plate 26 protrudes. The term "plate length" refers to the extent of the plate 26 in the longitudinal direction, i.e., in the direction of movement and tension. The plate length counteracts the overhang moment.

[0062] In one example, the spindle 18 is held at one end in the worm gear 32, which is designed as a spur gear, and at the other end in a bearing point 60 provided on the front side. The bearing point 60 is, for example, a plain bearing. For example, a sliding material is provided as the material.

[0074] The term "driver kit" refers to a modular system or kit for assembling a drive device. The drive device kit allows for different configurations, in this case, two different drive devices for a movable closure component such as a door. For example, the kit allows for the assembly of a closing aid and an opening aid using as many common parts as possible. This simplifies manufacturing, as well as assembly, maintenance, repair, replacement, and retrofitting.

[0075] The drive device kit can also be referred to as a drive device construction kit.

[0076] The term "spindle" refers to a rotating, elongated element with a thread for engaging a mating component, such as a spindle nut. The spindle is typically driven in rotation to effect linear movement of the mating component via the thread.

[0085] The term “base housing part” refers to the area of ​​the housing, or the part of the housing, that is consistent across different drive devices.

[0086] The term “connector housing part” refers to the area of ​​the housing, or the part of the housing, that is different for the various drive devices.

[0087] In a first example, the plunger 112 has a spindle nut 132 and is movably held in a first connection housing part type 134.

[0088] In a second example, the Bowden cable attachment 116 forms a spindle nut 136 and is movably held in a second connection housing part type 138.

[0089] The base housing part 128 and the connection housing part of the first connection housing part type 132 or the second connection housing part type 138 are connectable to one another for an assembled state of the drive device in order to optionally form a drive device for the door opening unit 114 or a drive device for the door closing unit 118.

[0093] For example, the first and second force directions are the same force direction.

[0094] As an option, it is also shown that the spindle is arranged in the connection housing part and the first connection housing part type 132 and the second connection housing part type 138 are interchangeably attachable to the base housing part 128.

[0095] The term “interchangeable” refers to the possibility of using the two types of connector housing parts, at least during assembly.

[0096] In one example, the connection housing part types can also be subsequently removed from the base housing part and replaced or exchanged with the other connection housing part type.

[0097] In an option not shown in detail, the spindle nut of the tappet has a first pitch, and the spindle nut of the Bowden cable attachment has a second pitch that is smaller than the first pitch. The spindle of the actuating device is interchangeably mounted on the transmission device. Furthermore, a first spindle matching the first pitch or a second spindle matching the second pitch can be selected.

The movement device 152 is movable by the actuating component.

[0101] The movement module can also be referred to as a lock module. The term "movement device" refers to the components used to transmit force to the movable closure component. The movement device could be, for example, an extension plunger for opening a vehicle door to a certain extent, or a Bowden cable acting on a rotary latch to close a door by rotating the rotary latch, which is already engaged with a striker, for example, in a pre-notch of a door lock, so that the door is pressed into the seal.

[0102] Fig. Figure 8a shows, as an option, a first example of the movement module 150, which is designed as a door positioning unit 114. The movement device 152 is the plunger of the actuating device, with which a relative force can be applied between the closure component and the door frame structure.
