Abstract

A drive member (1) comprising a first rotary part (2) and a second rotary part (3) designed to rotate together around a common centre line and to rotate relative to each other around said centre line. The drive member further comprises a rotation limiter (5) between the two rotary parts, designed such that when the first rotary part is driven to rotate, the first rotary part, after passing a free angular travel, causes the second rotary part to rotate together in an angular position determined by the rotation limiter, i.e. a carry-over angle. The rotation limiter comprises an indexer (36) that is activated by rotation of the first and / or second rotary element, in a continuous drive cycle on the drive element, wherein the first rotary element is driven from rest to rotation and, after including the second rotary element, is again at rest.

Description

Technical Field

[0001] The present invention relates to a drive component, such as an adjustment device for adjusting the external vision unit of a motor vehicle. Background Technology

[0002] Adjustment devices for external vision elements of motor vehicles typically include a carrier supporting an external vision unit, such as an external mirror, camera, LIDAR, and / or display. The carrier may thus be part of the housing of the external vision unit or form a separate part thereof. The carrier is typically adjustable relative to an adjustment device base to be mounted on the motor vehicle via an actuator (specifically an electric actuator), and then adjustable or non-adjustable relative to the housing of the external vision unit.

[0003] Adjustment mechanisms are typically used to adjust a visual unit around multiple adjustment axes, particularly around axes of upright orientation relative to a fixed world and axes of supine orientation relative to a fixed world. For example, when the external visual unit is in the driven position, the angle of view of the driver via the external visual element can be set. Adjustment around the upright axis can then typically be made in two directions (i.e., from left to right and from right to left). Similarly, adjustment around the supine axis can typically be made in two directions (i.e., from bottom to top and from top to bottom). In practice, the term "mirror glass actuator" is commonly used. The adjustment mechanism typically comprises two housing parts pivotally connected to each other: a fixed part for connection to a support frame and an adjustment part for connection to the external visual unit. Typically, the output part is connected to the fixed part via two separate actuators, each with its own electric motor, such that the adjustment movement of the output part carrying the external visual unit can be driven for each adjustment axis.

[0004] Furthermore, the adjustment device can be used to adjust the vision unit between a parked position and an extended drive position, in which the carrier extends substantially along the vehicle and in the extended drive position, the carrier extends substantially laterally to the vehicle. This actuator is typically referred to by the term "electric folding actuator." The base of the adjustment device generally includes a base for mounting on an external portion of the vehicle body, and a base shaft extending from the base along an axis of upright orientation relative to a fixed world, which is used to receive the carrier in a pivotable manner about the base shaft, particularly for a carrier frame for mirror actuators. Typically, the carrier is connected to the base by a separate actuator having its own electric motor, such that the pivoting movements of the carrier inward and outward folding can be driven.

[0005] In many cases, the adjustment device can be equipped with an actuator having two drives, each with its own electric motor, used for pivoting movements of the carrier to fold inward and outward, and for adjusting movements of the carrier around an upright axis and / or a lying axis. The external vision unit can then be considered a dual-axis electrically operated folding actuator, or a mirror glass actuator with electrically operated folding functionality. In such an adjustment device with a single actuator, the pivot axis can coincide with the upright adjustment axis. Such an adjustment device is described in EP 3218226.

[0006] In practice, adjusting devices typically consist of an electric motor for each axis to be adjusted and a drive shaft connected thereto, which cooperates with an adjusting axis along a fixed drive path via a transmission. The direction of rotation of the adjusting axis can then be changed simply by reversing the direction of rotation of the electric motor.

[0007] This is disadvantageous because for each axis to be adjusted, a circuit is required that can reverse the direction of motor rotation. In the case of a DC electric motor, such as in a car door, a switch and wiring are required for each axis to be adjusted, which can reverse the polarity of the motor wiring.

[0008] Because the external vision unit often needs to be adjusted around two adjustment axes, in practice, the actuators for the adjustment devices include more than one electric motor. This is disadvantageous because electric motors are relatively expensive and occupy sometimes limited space.

[0009] To overcome the above-mentioned drawbacks, an attempt has been made to provide a drive device for adjusting the instrument, which allows the external vision unit to be adjusted around two adjustment axes using only a single electric motor.

[0010] In this regard, NL 1007139 describes an actuator for adjusting a device, particularly for pivoting a carrier element of a vehicle's exterior rearview mirror, whereby the carrier element of the vehicle's exterior rearview mirror can be pivoted separately about upright and horizontal adjustment axes by means of a single electric motor. The actuator includes a single electric motor and a drive shaft connected thereto, which cooperates with a first adjustment shaft and a second adjustment shaft respectively via a transmission. The first adjustment shaft is driven only when the drive shaft rotates in a first direction of rotation, and the second adjustment shaft is driven only when the drive shaft rotates in the opposite second direction of rotation. Each of the two adjustment shafts is connected to the carrier element via a rotation-translation converter. Each rotation-translation converter includes a rotating disk with an eccentric locating pin received in two mutually laterally oriented straight slots on the carrier element. During actuation, the pin moves cyclically up and down in the slots, allowing the carrier element of the exterior rearview mirror to pivot separately about the upright and horizontal adjustment axes. While this device does have advantages, it also has disadvantages. For example, when the desired angular position has been reached, due to the cyclical nature of the adjustment, it is necessary to continue adjusting to the limit position before the desired angular position can be found again. Furthermore, the adjustment speed is not constant and gradually increases from low to high between the limit position and the neutral position. Because the set position is usually near the neutral position, the desired set position may be missed due to high speed, and therefore a long wait is required before the desired position can be approached again, at which point the speed is increased again.

[0011] Furthermore, an actuator for adjusting devices is known from WO2003 / 086816, particularly an actuator for pivoting the support element of an exterior rearview mirror of a motor vehicle, whereby the support element of the vehicle's exterior rearview mirror can pivot in two adjustment directions respectively about an upright and a horizontal adjustment axis by means of a single DC electric motor. This actuator includes a single electric motor with a drive shaft connected via a centrifugal clutch having two drive paths, each leading to a different adjustment shaft. When the electric motor is energized, it initially adjusts the first adjustment shaft via the first drive path in each rotational direction under each condition, and adjusts the second adjustment shaft via the second drive path when the electric motor exceeds a certain speed (rpm) during energization. While this device does have advantages, it also has disadvantages. For example, the motor must first rotate before the rotational direction can be changed to reach the second drive path, which can lead to undesirable adjustments via the first drive path. Moreover, due to the different speeds of the electric motor, the noise generated by the actuator varies greatly when adjusting in different rotational directions. This may be the last annoyance experienced by the vehicle driver. Finally, the difference in available power for adjusting each axis lies in the speed (rpm). This means that either a more powerful electric motor must be selected, which increases the cost, or in some cases, such as extremely cold conditions, the electric motor has insufficient power in the adjustment direction with the lowest speed, resulting in the adjustment device not adjusting in that direction.

[0012] Similarly, in other applications of adjustment equipment, it is desirable to be able to configure its actuators for multiple functions without requiring separate electrical controllers or circuits. Therefore, it may be desirable to be able to adjust the headrest not only in height but also in angular position using the same electrical actuator, for example, without providing an electrical controller or circuit, or, in the case of a drilling rig, to be able to rotate the drill bit not only in two directions but also to actuate and unload the chuck for the drill bit. Summary of the Invention

[0013] This invention envisions a drive component for adjusting an instrument that, while retaining the aforementioned advantages, can overcome the aforementioned disadvantages. In this regard, the invention specifically considers a drive component that, using a driver and a motor, allows the adjustment shaft to be adjusted in opposite rotational directions in one direction of rotation, particularly at a constant adjustment speed and at an equal motor speed. Furthermore, the invention envisions a drive component that, using a driver with an electric motor, enables adjustment around two adjustment axes. This drive component allows the user to select the adjustment axis and / or the adjustment direction around the corresponding adjustment axis, while maintaining a constant adjustment speed and simultaneously adjusting the adjustment shaft at an equal electric motor speed, and, importantly, eliminating the need for an electrical controller or circuitry.

[0014] To this end, the present invention provides a driving component comprising a first rotating portion and a second rotating portion, the first rotating portion and the second rotating portion being arranged to rotate together about a common central axis and to rotate relative to each other about the central axis. The driving component further includes a rotation limiter operating between the two rotating portions, the rotation limiter restricting rotation between the rotating portions.

[0015] The rotation limiter is arranged such that when the first rotating part is driven to rotate, after the first rotating part has traveled a free angle, the second rotating part rotates together with it at a mutual angular position (i.e., a bearing angle) determined by the rotation limiter.

[0016] The rotation limiter includes an indexer that is excited by the rotation of the first rotating part and / or the second rotating part, such that in multiple consecutive drive cycles on the drive member, in each drive cycle, the first rotating part is driven from a stationary position to rotation, and after being carried together with the second rotating part, it is stationary again, the carried together angle is indexed, and in multiple consecutive drive cycles, the relative angular positions of the rotating parts being carried together are different.

[0017] By providing a rotation limiter with a rotational excitation indexer, the first and second rotating portions of the drive component have different relative angular positions when carried together during continuous excitation, allowing the drive component to exhibit different configurations during continuous excitation. Therefore, the drive component can be mechanically controlled by continuous excitation of the drive. The rotation limiter can be configured to limit rotation between or between portions of the rotating portions per revolution. Thus, a series of angular positions can be continuously traversed, for example, in a cycle. Preferably, the difference between the first angular position and another angular position is 360 / n, where n is a natural number between 1 and 12, such as 360°, 180°, 120°, 90°, 72°, 60°, 45°, 40°, 36°, or 30°.

[0018] By arranging the first rotating part to carry the second rotating part at a first angular position and / or another angular position via a rotation limiter during rotation, such that the rotating parts rotate together about the central axis, it is possible, by means of a drive member, to drive the load in a conventional manner.

[0019] When the indexer is equipped with a transmitter configured to pass at least one rotating part through a rotation limiter, such that the rotating parts are indexed relative to each other, the drive components can be implemented in a relatively simple manner.

[0020] When the rotation limiter includes cooperative blocking elements located on the first and second rotating portions respectively, it is possible to achieve, in a relatively simple manner, that the rotating portions support each other during rotation, thereby rotating together around the central axis.

[0021] By arranging the transmitters in a manner that allows for the radial and / or axial adjustment of the cooperative blocking elements of the rotation limiters relative to each other for the passage of the rotating portion, the drive components can be made into a compact design, particularly in the radial range.

[0022] When the transmitter includes a rotary-translational converter, the indexing mechanism can be relatively easily integrated into the drive unit, and the drive unit can relatively easily change its configuration during continuous excitation. In particular, with the aid of such a drive unit, the driver can relatively easily mechanically switch between configurations through continuous excitation cycles of the driver.

[0023] When the transmitter includes a slider extending transversely to the central axis, the blocking elements can be selectively moved to engage and / or disengage from each other.

[0024] By providing a rotational excitation to the transmitter, which excites the transmitter as one of the rotating parts rotates, it is possible, with the aid of a conventional drive transmitter, that the indexing of the rotating parts relative to each other can be configured differently by rotational mechanics. Particularly preferably, as the first rotating part rotates, the second rotating part can be indexed relative to the first rotating part.

[0025] When the rotational excitation includes centrifugal excitation, the rotating portion can relatively easily adopt different configurations during continuous excitation with the aid of so-called centripetal acceleration or centrifugal force. Specifically, when the transmitter is eccentrically implemented and, for example, positioned on the first rotating portion, the slider of the transmitter is excited and seeks to change its position due to centrifugal force as the first rotating portion rotates. In this way, for example, a cam in a cam and groove pair can press against the surface of the second rotating portion until the cam aligns with the receiving groove and then engages in the receiving groove, such that the rotating portions are indexed relative to each other. Additionally or optionally, the drive component may include one or more eccentric weights adjustable between an inner position positioned radially inward and an outer position positioned radially outward, and these one or more eccentric weights can excite the transmitter during rotation via corresponding stop surfaces, particularly by centrifugal excitation.

[0026] When the transmitter is under the action of a spring, especially when resisting rotation, and even more so when resisting centrifugal excitation, it is possible to achieve the initial configuration of the transmitter as the rotation of the driving component decreases in a relatively simple way.

[0027] By arranging at least one rotating part to provide operating pulses during restricted rotation between consecutive angular positions of the rotating part, it is possible to make the rotating parts indexed relative to each other at consecutive angular positions in a relatively simple manner.

[0028] When the rotating parts cooperate via a rotation-translation converter, and the restricted rotation between consecutive angular positions causes axial displacement of the rotating parts relative to each other, the mechanical indexing of the rotating parts relative to each other can be achieved with a relatively simple construction.

[0029] By forming the second rotating portion as an output shaft or connecting it to an output shaft, and by arranging at least one rotating portion to provide operating pulses through axial translation during restricted rotation between consecutive angular positions of the rotating portion, the driver can be mechanically controlled by means of a driving component through continuous excitation of the driver.

[0030] The present invention also relates to a drive comprising an electric motor, particularly a DC electric motor, and a drive component as described above, wherein the output shaft of the electric motor is coupled to the first rotating portion, and wherein the first rotating portion and / or the second rotating portion of the drive component cooperates with another component of the drive. Thus, a drive that can be mechanically controlled by continuous excitation of an electric motor can be readily provided.

[0031] Another component of the drive is preferably or includes a transmission device, wherein the output shaft cooperates with the transmission device, and wherein the output shaft has a first axial position in a first angular position in which the output shaft drives a first transmission path of the transmission device, and a second axial position in another angular position in which the output shaft drives a second transmission path of the transmission device.

[0032] The present invention also relates to a method for driving an adjusting device, which particularly includes the driver described above, wherein a first rotating portion and a second rotating portion of a driving member, driven by an electric motor, are indexed relative to each other in mutual angular positions by rotation between the first rotating portion and the second rotating portion, which are limited at successive angular positions. It should be noted that the technical features of the driver as described in the preceding paragraphs can also be advantageously applied, on their own, to drivers with different configurations; that is, these individual technical features can be isolated from their context and used individually, and, if desired, combined with one or more of the aforementioned features. The invention will be further explained based on exemplary embodiments illustrated in the accompanying drawings. Attached Figure Description

[0040] It should be noted that the accompanying drawings are merely illustrative representations of preferred embodiments of the invention, and these are given by way of non-limiting exemplary embodiments. In the exemplary embodiments, the same or corresponding parts in different embodiments are indicated by the same reference numerals.

[0041] Figure 1 A first embodiment of a drive component 1 according to the present invention is shown. The drive component 1 includes a first rotating portion 2 and a second rotating portion 3. The two rotating portions 2 and 3 are arranged to rotate together about a common central axis 4 and to rotate relative to each other about the central axis 4. The drive component 1 also includes a rotation limiter 5 operating between the two rotating portions 2 and 3. The rotation limiter 5 is designed such that when the first rotating portion 2 is driven to rotate, after a free angular travel, the first rotating portion 2 causes the second rotating portion 3 to rotate together at a mutual angular position defined by the rotation limiter 5. In this first embodiment, the rotation limiter 5 is configured to restrict the rotation between the rotating portions 2 and 3 to a first mutual angular position α1 between the rotating portions 2 and 3.

[0042] The rotation limiter 5 includes an indexer 36 excited by the rotation of the first rotating part 2. The indexer 36 ensures that the angle of bearing together is indexed in a continuous drive cycle on the drive member 1, and that the angular positions of the rotating parts 2 and 3 are different when they are bearing together in a continuous drive cycle. In each drive cycle, the first rotating part 2 is driven from a stationary position to rotation, and after bearing together with the second rotating part 3, it returns to a stationary position at the end of the drive cycle.

[0043] The indexer 36 is provided with a transmitter 6. The transmitter 6 is arranged such that the rotating part 3 passes through the rotation limiter 5, such that the rotating parts 2 and 3 are indexed relative to each other and can be further rotated relative to each other to another mutual angular position α2 between the rotating parts 2 and 3. The rotation limiter 5 thus limits, for example, a series of angular positions αn, which are passed continuously in a cycle by the action of the indexer 36 (specifically by the transmitter 6 of the indexer 36 in this example). In the example shown, according to the formula 360° / n (where n = 2), the difference between the first angular position α1 and the other angular position α2 relative to each other is therefore 180°. The first rotating part 2 is arranged to carry the second rotating part 3 via the rotation limiter 5 during rotation in the first angular position α1 and / or the other angular position α2, such that the rotating parts 2 and 3 rotate together about the central axis 4.

[0044] The transmitter 6 is arranged such that each time the first rotating part 2 rotates again relative to the second rotating part 3 and is restricted, the rotating part 3 passes through the rotation limiter 5, so that the rotating parts 2 and 3, which are carried together, are indexed relative to each other in angular position. This is in Figure 2A and 2B The top view shows this, which will be explained in more detail in the instruction manual.

[0045] The rotation limiter 5 includes cooperative blocking elements 7 located on the first rotating portion 2 and the second rotating portion 3, respectively. The cooperative blocking element 7 includes a cooperative cam pair 8. The cam pair 8 includes a radially inwardly extending cam 8a on the transmission member 6 and a radially outwardly extending cam 8b on the surface of the second rotating portion 3, the transmission member 6 being carried on the first rotating portion 2. Additionally or alternatively, the cooperative cam pair 8 can be implemented as a pair of cams 8 facing each other axially, arranged on corresponding portions 2 and 3. Figure 1 and 2A In the diagram, the cams 8a and 8b of the cooperating cam pair 8 are shown to be engaged with each other. Therefore, the rotation between the rotating parts 2 and 3 is restricted to the first angular position α1.

[0046] Figure 2B The state in which the transmitter 6 of the indexer 36 allows the rotating part 3 to pass through the rotation limiter 5 is shown. The cams 8a and 8b of the cooperative cam pair 8 are shown disengaged from each other and therefore can pass each other.

[0047] In this example, the cooperative blocking element 7 also includes a cooperative cam and groove pair 9. As shown, the cooperative cam and groove pair 9 includes a radially inwardly extending cam 9a on the transmitter 6 on the first rotating portion 2 and a receiving groove 9b located in the surface of the second rotating portion 3. In this example, the cooperative cam and groove pair 9 can produce a travel stroke β of approximately 10°. Therefore, the receiving groove 9b restricts rotation between the rotating portions 2 and 3 to another angular position α2 (not shown). In the exemplary embodiment shown, the cooperative cam and groove pair 9 is arranged opposite to the cooperative cam pair 8. Additionally or alternatively, the cooperative cam and groove pair 9 may be arranged at an angle between 90° and 180° relative to the cooperative cam pair 8.

[0048] Continuous Figure 2A and 2B The transmitter 6 of the indexer 36 is arranged for the mutual passage of the rotating parts 2 and 3 to adjust the cooperating blocking element 7 of the rotation limiter 5 at least radially relative to each other. Alternatively or additionally, for the mutual passage of the rotating parts 2 and 3, the transmitter 6 may be arranged to adjust the cooperating blocking element 7 of the rotation limiter 5 axially relative to each other.

[0049] Figure 3 The drive component 1 of the first embodiment is shown in an exploded view. Figure 3 As can be appropriately seen, the transmitter 6 includes a slider 11 extending transversely to the central axis 4. The transmitter 6 is provided with radially inwardly extending cams 8a and 9a, which are disposed opposite to each other on the slider 11. As described above, the cams 8a and 9a are part of the cooperating blocking element 7. An elongated slot 11a extends between the radially inwardly extending cams 8a and 9a. The slot 11a is arranged to cooperate with the first rotating portion 2, such that the transmitter 6 can be adjusted between a first position I and a second position II, in which the cooperating cam pair 8a and 8b engage with each other. Figure 2A In the second position II, the cooperating cam pairs 8a and 8b can pass over each other, and the cooperating cams and slot pairs 9a and 9b are interlocked so that the first rotating part 2 can rotate freely relative to the second rotating part 3. Then the cooperating cam pairs 8a and 8b can pass over each other. Figure 2B At the end of the free rotation stroke, the radially inwardly extending cam 9a cooperates with the edge of the groove 9b, so that the rotating parts 2 and 3 are in another mutually angular position α2 indexed by the transmitter 6 of the indexer 36, wherein the rotation limiter 5 again restricts the rotation between the rotating parts 2 and 3, and the rotating parts 2 and 3 can once again carry each other together.

[0050] exist Figure 1-3The diagram shows a rotation limiter 5 comprising an indexer 36 rotated by the rotation of a first rotating portion 2. This relates particularly to the rotational excitation 12 of the transmitter. This excitation is implemented as a centrifugal excitation, which actuates the transmitter 6 as the first rotating portion 2 rotates. The centrifugal excitation 12 comprises two eccentric weights 12a pivotally disposed on the first rotating portion 2. Each pivotally disposed eccentric weight 12a is pivotable about its own pivot axis 13, which is eccentrically positioned relative to the central axis 4. In the example shown, the pivot axis 13 extends substantially along the central axis 4, but of course, the pivot axis 13 could also extend at an angle to the central axis 4. The pivotally disposed eccentric weights 12a are adjustable between a radially inward inner position R1 and a radially outward outer position R2.

[0051] Each pivotally mounted eccentric counterweight 12a is provided with a push surface (not shown) adjacent to the pivot axis 13. This push surface is arranged to cooperate with a receiving surface provided on the transfer member 6, allowing the transfer member to be adjusted laterally to the central axis between a first position I and a second position II. In the radially outer position R2, the eccentric counterweight 12a is located within the outer contour of the first rotating portion. Thus, the structure can have a relatively compact design.

[0052] The transmitter 6 is under the spring action of the push spring 16, which in particular resists the rotational excitation 12. As a result, when the rotation decreases and / or terminates, the transmitter 6 adjusts from the second position II (return) to the first position I, and the cooperating cam pair 8 are once again in each other's paths.

[0053] It will be apparent to those skilled in the art that the transmitter 6 itself can also be provided with an eccentric design and / or with a pivotally set eccentric counterweight 12a, such that the transmitter 6 can be adjusted laterally between a first position I and a second position II on the central axis 4. The transmitter 6 and / or the pivot axis 13 can then be designed such that, when the rotation of at least the first rotating portion 2 has stopped, the transmitter 6 is (re)adjusted from the second position II to the first position I under the influence of gravity.

[0054] exist Figure 2A In the first position (I), the transmitter 6 is in the first position (I). As the first rotating part 2 rotates, the pivotally mounted eccentric counterweight 12a adjusts from the radially inner position (R1) to the radially outer position (R2), resulting in the transmitter 6 adjusting from the first position (I) to the second position (II) through the cooperation of the pushing surface 14 and the receiving surface 15. Figure 2B In the middle, the transmitter is in the second position II, in which the radially inwardly extending cam 9a is aligned with and pressed into the receiving groove 9b, and the cooperating cam pair 8 can pass over each other.

[0055] Therefore, in the continuous drive cycle on the drive component 1, in each drive cycle, the first rotating part 2 is driven from a stationary position to rotation, and after bearing the second rotating part 3 together, it is stationary again, the bearing angle is indexed, and the relative angular positions of the rotating parts 2 and 3 in bearing together in the continuous drive cycle are different. These differences in relative angular positions can be used to change the configuration of the driver 25, of which the drive component 1 is a part, and thereby control the driver 25. In this embodiment, the second rotating part 3 is arranged, for example, to provide an operating pulse during restricted rotation between the consecutive relative angular positions α of the rotating parts 2 and 3. For this purpose, the drive component 1 is provided with a rotation-translation converter 10. The rotation-translation converter 10 includes fingers 10a located on the second rotating part 3, which are arranged to cooperate slidably with a receiving surface 10b (in particular a helical groove) on the first rotating part 2 in axial longitudinal guidance. Using such operating pulses, for example, the central shaft of the adjustable gear transmission 29 connected to the drive component 1 can be adjusted.

[0056] Figures 4.1A-4.11C A second embodiment of the drive component 1 is shown. Figures 4.1A-4.11C Based on this, the rotational excitation 12 (particularly the centrifugal excitation) manifests in a series of steps, which will be further explained below. The second embodiment includes the same elements as the first embodiment described above. Regarding the first embodiment, the rotation limiter 5 includes additional cooperating blocking elements 7 located on the first rotating portion 2 and the second rotating portion 3, respectively, wherein the second rotating portion 3 is provided with a second radially outwardly extending cam 18 and a second receiving groove 19, the second radially outwardly extending cam 18 being arranged opposite to the central axis 4 and away from the radially outwardly extending cam 8b along the central axis 4, the second receiving groove 19 being arranged opposite to the central axis 4 and away from the receiving groove 9b along the central axis 4, and wherein the first rotating portion 2 is provided with another receiving groove 20 near the inwardly extending cam 9a. The radially inwardly extending cam 9a is arranged to cooperate with the receiving groove 9b in the second position II of the transmitter 6. The radially inwardly extending cam 9a is also arranged to cooperate with the second receiving groove 19 in the second position II of the transmitter 6, while the radially outwardly extending cam 8b cooperates with the other receiving groove 20. Therefore, in the continuous drive cycle on the drive component 1, in each drive cycle, the first rotating part 2 is driven from a stationary position to rotation, and after carrying the second rotating part 3 together, it is stationary again, the angle of carrying together is indexed, and the relative angular positions of the rotating parts 2 and 3 in carrying together in the continuous drive cycle are different. The additional cams and grooves increase the operational reliability of the drive component 1.

[0057] Figures 4.1A-4.11C The stepping rotation of the drive component 1 is shown, thereby driving the first rotating part 2. Figures 4.1A-4.6CIn each case, the second rotating portion 3 rotates to illustrate the operation of the second embodiment.

[0058] exist Figures 4.1A-4.1C In the first position B, the sliding member 11 (especially the transmission member 6) is in the first position I. The eccentric counterweight 12a is in the radially inner position R1. The second rotating part 3 is in the first axial position A1.

[0059] exist Figures 4.2A-4.2C In the process, the angular position α between the first rotating part 2 and the second rotating part 3 has changed due to the clockwise rotation of the first rotating part 2.

[0060] exist Figures 4.3A-4.3C In the process, the angular position α has increased until the cooperating cam pair 8 cooperates, causing the rotation limiter 5 to restrict the rotation between the rotating parts 2 and 3 to the angular position α1. Figure 4.3C The image shows that the second rotating part 3 has been axially shifted relative to the first rotating part 2 along the central axis 4 to the second axial position A2 by the rotation-translation converter 10.

[0061] exist Figures 4.4A-4.4C In this process, the eccentric counterweight 12a has been adjusted to the radially outer position R2 by the rotational excitation 12 (especially the centrifugal excitation). By means of the cooperation between the pushing surface 14 and the receiving surface 15, the transmitter 6 is also adjusted from the first position I to the second position II by the rotational excitation 12 (especially the centrifugal excitation).

[0062] exist Figures 4.5A-4.5C In the first rotation, the second rotating part 3 has rotated relative to the first rotating part 2 through a stroke β, and the radially outward-extending cam 8b has passed the radially inward-extending cam 8a, while the radially inward-extending cam 9a cooperates with the receiving groove 9b. As long as the second rotating part 3 rotates, due to centrifugal excitation, the radially inward-extending cam 9a and the receiving groove 9b continue to cooperate, resulting in the second rotating part 3 rotating together with the first rotating part 2 at a second axial position A2 via the rotation limiter 5.

[0063] exist Figures 4.6A-4.6C In the middle, the rotation has stopped, and the driving component 1 is in the second position E[ε], wherein the second rotating part 3 is in the second axial position A2 ( Figure 4.6C ), the eccentric counterweight 12a is once again in the radially inner position R1 ( Figure 4.6A And transmitter 6 is once again in the first position I ( Figure 4.6A ).

[0064] When the first rotating part 2 is energized again from the second position E, the second rotating part 3 will move axially along the central axis 4 to the first axial position A1 in the opposite manner via the rotation-translation converter 10. Upon termination of rotation, the drive component 1 will return to the first position B. This... Figures 4.7A-4.11C As shown in [the image]. Figures 4.7A-4.11C In each case, both the first rotating part 2 and the second rotating part 3 rotate.

[0065] exist Figures 4.7A-4.7C In the process, the angular position α between the first rotating part 2 and the second rotating part 3 has changed due to the clockwise rotation of the first rotating part 2.

[0066] exist Figures 4.8A-4.8C In the middle, the angular position α has increased until the inwardly extending cam 8a cooperates with the outwardly extending cam 18, causing the rotation limiter 5 to restrict the rotation between the rotating parts 2 and 3 to the angular position α2. Figure 4.8C The image shows that the second rotating part 3 has been axially shifted relative to the first rotating part 2 along the central axis 4 to the first axial position A1 by the rotation-translation converter 10.

[0067] exist Figures 4.9A-4.9C In this process, the eccentric counterweight 12a has been adjusted to the radially outer position R2 by the rotational excitation 12 (especially the centrifugal excitation). By means of the cooperation between the pushing surface 14 and the receiving surface 15, the transmitter 6 is also adjusted from the first position I to the second position by the rotational excitation 12 (especially the centrifugal excitation).

[0068] exist Figures 4.10A-4.10C In this process, the second rotating part 3 has rotated relative to the first rotating part 2 through a stroke β, and the radially outward-extending cam 18 has passed the radially inward-extending cam 8a. Simultaneously, the radially inward-extending cam 9a cooperates with the second receiving groove 19, and the radially outward-extending cam 8b cooperates with another receiving groove 20. As long as the second rotating part 3 rotates, the radially inward-extending cam 9a and receiving groove 19, and the radially outward-extending cam 8b and receiving groove 20, continue to cooperate due to centrifugal excitation. Therefore, the second rotating part 3 rotates together with the first rotating part 2 at the first axial position A1 via the rotation limiter 5.

[0069] exist Figures 4.11A-4.11C In the middle, the rotation has stopped and the drive component 1 is back in the first position B.

[0070] Rotating portions 2 and 3 cooperate via a rotation-translation converter 10. Constrained rotation between consecutive angular positions α causes radial and / or axial displacement of rotating portions 2-3 relative to each other. For this purpose, the drive member 1 in the two embodiments described above is provided with fingers 10a (not shown) cooperating with an annular helical groove 10b, allowing rotating portion 23 to move axially up and down relative to each other along the central axis 4. A second rotating portion 3 forms an output shaft 24. Alternatively or additionally, the second rotating portion 3 may be coupled to the output shaft 24, for example, as shown in the image. Figure 5 As shown, and will be further explained below, the second rotating part 3 is arranged to provide an operating pulse by axial translation during restricted rotation between consecutive angular positions α of the rotating parts 2 and 3.

[0071] Figure 5 A further detailed example of a driver 25 according to the invention is shown. Driver 25 includes an electric motor 26, particularly a DC electric motor. Furthermore, driver 25 includes a drive component 1. The drive component includes a first rotating portion 2 and a second rotating portion 3. In this example, the rotating portions are arranged to rotate together about a common central axis and relative to each other about this axis. The second rotating portion 3 is axially adjustable relative to the first rotating portion 1 between a first position and a second position. In this example, drive component 1 is implemented as in the second embodiment of the application example described above. However, the second rotating portion 3 can also be axially adjusted relative to the first rotating portion 2 between the first position and the second axial position in a manner different from rotation relative to the aforementioned rotary excitation indexer, for example, by means of electromagnetically operated axial displacement.

[0072] The output shaft 27 of the electric motor 26 is fixedly connected to the first rotating part 2. The second rotating part 3 is axially adjustable relative to the first rotating part 2. The second rotating part 3 of the drive component 1 further cooperates with the output shaft 24 of the drive component 1 in an axially telescopic manner via a rotation-translation converter 40. The second rotating part 3 and the output shaft 24 together form an axially telescopic drive shaft. In this example, the cylindrical output shaft 24 of the drive component 1 is slidably accommodated in the hollow cylindrical shaft portion of the second rotating part 3, and one of the two components is provided with one or more pins, which are accommodated in one or more corresponding helical grooves in the other component. Alternatively, for example, a thread that operates between the two components can be selected. The output shaft 24 of the drive component, in turn, cooperates with another component 28 of the drive 25, particularly via a gear 32 carried on the output shaft 24. By using the rotation-translation converter 40, the gear 32 can slide into the drive shaft position corresponding to the first rotation direction M+ of the motor 26 (in Figure 5 As shown in the diagram, and generated by a rightward drive) and the slip-out drive shaft position corresponding to the opposite rotation direction M- of motor 26 (in Figure 5(Not shown in the diagram, and generated by a leftward drive) Axial adjustment between (the two).

[0073] In this exemplary embodiment, another component 28 of the driver 25 is the transmission 29. The output shaft 24 cooperates with the transmission 29. When the motor 26 is driven in a first direction M+ (to the right in this example), the output shaft 24 selectively cooperates with either the input gear 33 of the first drive path 30 (indicated by a dashed line) or the input gear 34 of the second drive path 31 (indicated by a full dot) of the first output branch 42 of the transmission 29. When the motor 26 is continuously energized in the same direction (and therefore to the right in this case), the output shaft 24 can then switch between the first drive path 30 and the second drive path 31 of the first output branch 42 of the transmission 29 by axial adjustment of the second rotating portion 3 relative to the first rotating portion 2. In a first angular position α1 of the second rotating portion 3 relative to the first rotating portion 2, the output shaft 24 has a first axial position A1 in which the output shaft 24 drives the first drive path 30 of the transmission 29. In this other angular position α2, the output shaft 24 has a second axial position A2, in which the output shaft drives the second drive path 31 of the transmission 29 (not shown). In both axial positions A1 and A2, the axially telescopic rotary-translational converter 40 is always in a sliding drive shaft position. The output shaft 24 includes a gear 32 that cooperates in the first drive path 30 with an input gear 33 included in the first output branch 42 of the transmission 29 to rotate the first output element 41 of the transmission 29 (here, the first worm gear) in the first rotational direction P1+. In the second drive path 31, the gear 32 cooperates with the input gear 34 included in the transmission 29 to rotate the first output element 41 of the transmission 29 in the opposite rotational direction P1- via an intermediate gear pair 35. In this way, it can be achieved that the output shaft 24 of the transmission 29 can drive the first output element 41 of the transmission 29 in two opposite rotational directions P1+ and P1- in a continuous drive cycle in the same drive direction. It should be noted that when adjusting between the two axial positions A1 and A2, gear 32 moves together with another input gear 46, but does not remain engaged with it to drive gear 46. This input gear has a third drive path 44, as described below, located in the second output branch 45 of the transmission. When motor 26 is driven in the opposite direction M-, in this case to the left, the drive shaft will advance to the slide-out drive shaft position by means of the axial telescoping rotation-translation converter 40. When motor 26 is driven in this second opposite direction, output shaft 24 selectively cooperates with input gear 46 of the third drive path 44 (indicated by a cross) and input gear 47 of the fourth drive path 48 (indicated by a hollow dot), respectively. The third drive path 44 and the fourth drive path 48 are located in the second output branch 45 of the transmission 29.When the motor 26 is continuously energized in the same direction M, the output shaft 24 can switch between the third drive path 44 and the fourth drive path 48, and is therefore on the left side in each case. In the first angular position α1 of the second rotating part 3 relative to the first rotating part 2, the output shaft 24 has a first axial position B1, in which the output shaft 24 drives the third drive path 44 (not shown) of the transmission 29. In the other angular position α2, the output shaft 24 has a second axial position B2, in which the output shaft drives the fourth drive path 48 (not shown) of the transmission 29. In both axial positions B1 and B2, the drive shaft with the axial telescoping rotation-translation converter 40 is always in the slip-out drive shaft position. The gear 32 of the output shaft 24 cooperates with the input gear 46 in the third drive path 44 to rotate the second output element 49 (here, the second worm gear) of the transmission 29 in the positive direction P2+. In the fourth drive path 48, gear 32 cooperates with input gear 47 included in the second output branch 45 of transmission 29 to rotate the second output element 49 of transmission 29 in the opposite direction of the second rotational direction P2 via intermediate gear pair 50. It should be noted that when adjusting between the two axial positions B1 and B2, gear 32 moves together with input gear 34 of the second drive path 31 of the first output branch 42, but does not remain engaged with it to drive gear 34.

[0074] In this way, it is possible to drive the second output element 49 of the transmission 29 in two opposite rotational directions P2+ and P2- via the second branch 45 of the transmission 29 when the shaft 24 of the transmission 29 is continuously driven in the same opposite driving direction M- (here, to the left) of the motor 26. In the case where each of the output elements 41, 49 is implemented as a worm gear, for example, the final stage of an actuator can be driven, such as the final stage 51 of the second output branch 45, to pivot the external vision unit (e.g., a camera or external mirror) of the motor vehicle about the adjustment axis. Therefore, using only one electric motor, by changing the rotational direction M- / M- of the electric motor 26, the external vision unit can pivot about two adjustment axes (e.g., x and y), and by continuously energizing the electric motor in the same directions M+ and M+ or M- and M-, it can pivot alternately in the positive or negative directions about the adjustment axis x or y.

[0075] It should be noted that this telescopic rotation-translation converter itself can also be considered as the present invention and can be configured in many embodiments. In this regard, based on the above examples, the following embodiments can be distinguished, for example:

[0076] Example

[0077] 1. A drive comprising an electric motor, particularly a DC electric motor, and a drive member having a first rotating portion and a second rotating portion, the second rotating portion being axially adjustable relative to the first rotating portion between the first position and the second position, wherein the output shaft of the electric motor is fixedly connected to the first rotating portion of the drive member, and wherein the second rotating portion of the drive member is axially telescopically connected to the output shaft of the drive member via a rotation-translation converter, such that the second rotating portion and the output shaft of the drive member together form an axially adjustable and telescopic drive shaft.

[0078] 2. The driver according to Embodiment 1, wherein the drive shaft is adjustable between a drive shaft entry position corresponding to a first rotation direction M+ of the motor and a drive shaft exit position corresponding to the opposite rotation direction M- of the motor.

[0079] 3. The driver according to embodiment 1 or 2, wherein the output shaft of the drive assembly cooperates with the transmission device.

[0080] 4. The driver according to any one of the foregoing embodiments, wherein the output shaft cooperates with the first output branch of the transmission in the drive shaft position and with the second output branch of the transmission in the drive shaft position.

[0081] 5. The driver according to Embodiment 4, which is subordinate to Embodiment 2, wherein the first output branch includes a first drive path and a second drive path, wherein the first output element can be driven in opposite rotational directions P1+ and P1- in the sliding drive shaft position of the first and second axial positions of the second rotating portion using the first drive path and the second drive path, and wherein the second output branch includes a third drive path and a fourth drive path, wherein the second output element can be driven in opposite rotational directions P2+ and P2- in the sliding drive shaft position of the first and second axial positions of the second rotating portion using the third drive path and the fourth drive path.

[0082] 6. The driver according to any one of the foregoing embodiments, wherein the output bearing of the driving component carries a gear.

[0083] 7. The driver according to Embodiment 6, which is subordinate to Embodiment 5, wherein the gear in the first drive path cooperates with the input gear included in the first output branch of the transmission device to rotate the first output element of the transmission device in a first rotational direction P1+, and wherein the gear in the second drive path cooperates with the input gear included in the transmission device to rotate the first output element of the transmission device in the opposite rotational direction P1-, and wherein the gear in the third drive path cooperates with the input gear included in the second output branch of the transmission device to rotate the second output element of the transmission device in a positive direction in a second rotational direction P2+, and the gear in the fourth drive path cooperates with the input gear to rotate the second output element in a negative direction in the second rotational direction P2-.

[0084] Note that the invention is not limited to the exemplary embodiments described herein. Many variations are possible.

[0085] Therefore, the present invention can be used, for example, in adjustable headrests, trunk lids, fuel tank / charging socket flap units, sunroofs, headlight adjustments, and / or side doors of vehicles. Furthermore, the present invention is particularly suitable, for example, for window trim, (security) cameras, or drilling machines.

[0086] Therefore, the adjustment module for operating the flap may include a drive component having the features described above, whereby the output adjustment element of the adjustment module is connected to a first rotating portion of the drive component for adjusting the flap between at least an open position and a covered position, and wherein the first rotating portion and / or the second rotating portion of the drive component cooperate with a lock of the flap via a transmission device for adjusting the lock between at least a locked position and an unlocked position.

[0087] By connecting the adjusting element of the adjusting module to the first rotating part of the drive component, the first and / or second rotating parts of the drive component cooperate with the lock of the wing via a transmission mechanism, making the opening and closing of the wing and the locking of the wing relatively simple to operate. Thus, for example, by a drive including an electric motor (particularly a DC electric motor), the vehicle's tailgate or loading wing can pivot about a pivot axis and / or translate along a guide rail (particularly a guide rail assembly) together with the adjusting module. Furthermore, the same drive can lock and / or unlock the loading wing. Additionally or alternatively, for example via such a drive, when the charging cable is connected to the vehicle during recharging, the folding portion of the vehicle's fuel tank / charging socket folding unit can be adjusted between open and / or covered, closed positions using the adjusting module, and the lock of the fuel tank / charging socket wing unit, particularly implemented as a pin lock, or the charging cable, particularly the charging cable plug, can be locked. In this way, decoupling of the charging cable during recharging can be counteracted.

[0088] Advantageously, the drive unit may be provided with a drive component having the aforementioned features, such that, during the first excitation, the output shaft of the drive unit is connected to the first rotating portion of the drive component, causing the first rotating portion to traverse the first adjustment stage via a transmission mechanism, thereby allowing adjustment at a relatively high speed and relatively low torque. Furthermore, during the second continuous excitation, the output shaft of the drive unit is connected to the first and / or second rotating portions of the drive component, causing the first and / or second rotating portions to traverse the second adjustment stage via another transmission mechanism, thereby allowing adjustment at a low speed and relatively high torque. In this way, for example, the trunk lid, fuel tank / charging valve flap unit, sunroof, and / or side doors of the motor vehicle can be conveniently closed and subsequently locked.

[0089] This configuration has a drive component with the aforementioned features, and optionally includes a drive adjustment module, which can also be used to adjust and / or lock, for example, the side doors, engine hood, and / or sunroof of the vehicle.

[0090] Furthermore, there are numerous power sources that generate couples, which, depending on the nature of their function, can generate couples only in one direction, such as water turbines, wind turbines, specific types of AC electric motors, and piezoelectric electric motors. One application could be to provide such power sources with drive components having the characteristics described above, such that, under continuous excitation, for example, the direction of rotation of the output shaft can be changed via a transmission mechanism. Moreover, such drive components can be applied in a cost-effective manner, for example, in sustainable energy fields such as solar cells, or in agricultural irrigation, particularly through simplified structures where fewer drives are needed to adjust between two, three, four, or more positions and / or multiple components.

[0091] This configuration includes a drive unit with the aforementioned features, and optionally includes an adjustment module for the drive unit, which can also be used, for example, to adjust and / or lock the vehicle's side doors, hood, and / or awning.

[0092] Therefore, in addition, an adjustment module for a window device having at least one slat, particularly a louver, for example... Or, a Venetian blind, may include a drive component equipped with the features described above, whereby the output shaft of the adjustment module is connected to the first rotating portion for adjusting the rotation of the at least one slat about its longitudinal axis, and whereby the first rotating portion and / or the second rotating portion of the drive component cooperate with the output element of the adjustment module for adjusting the translation of the at least one slat substantially transversely to its longitudinal axis along the guide of the adjustment module.

[0093] By connecting the output shaft of the adjustment module to the first rotating portion of the drive component, at least one slat can be adjusted about its longitudinal axis. The at least one slat can be adjusted between at least a shielded state and a released state, thereby controlling, for example, the amount of transmitted light. When the first and / or second rotating portions of the drive component cooperate with the output element of the adjustment module for adjusting at least one slat substantially transversely to its longitudinal axis along the guide of the adjustment module, it is possible to adjust at least one slat, for example, in height, particularly for one or more slats arranged horizontally in the guide, and / or to adjust at least one slat laterally, particularly for one or more slats arranged vertically in the guide. The guide can be implemented, for example, as a rail or rope. The adjustment module can be operated, for example, manually and / or electrically.

[0094] Such an adjustment module with a drive component having the aforementioned characteristics can also be used, for example, in a (security) camera to pivot the security camera about at least one lying axis and / or standing axis via the transmission of the adjustment module, or in a (head) bracket to adjust the (head) bracket in angular position and / or height. The adjustment module with the drive component can also be used to adjust more than two positions, such as three, four, or more, or even an unlimited number of positions.

[0095] Such variations will be apparent to those skilled in the art and are understood to be within the scope of the invention set forth in the appended claims.
