Description

Technical Field

[0001] The present invention relates to adjustment devices for external vision units such as external rearview mirrors, external displays and / or external cameras for vehicles, particularly motor vehicles. Background Technology

[0002] External vision units, such as exterior rearview mirrors, exterior displays, and / or exterior cameras, are applied to vehicles (e.g., sedans) and typically include a support frame for supporting the external vision elements (e.g., rearview mirrors or cameras).

[0003] The adjustment device is connected to a support frame and is designed to adjust the support frame about a base axis around which the adjustment device will be connected to the vehicle. The adjustment device typically includes a housing capable of pivoting relative to the base axis within an adjustment range (typically between a parking position and a driving position). In the parking position, the support frame extends substantially along the vehicle, for example, and with external rearview mirror units present, one side of the mirrors faces the vehicle. In the driving position, the support frame extends substantially laterally to the vehicle, for example, and with external rearview mirror units present, one side of the mirrors faces rearward relative to the normal driving direction. Typically, the housing can be connected to the base axis via an actuator, allowing the pivoting movement of the housing to be actuated in an actuated manner, thereby closing and opening the support frame. The support frame also typically supports a cover member that encloses the support frame and partially surrounds the external vision element.

[0004] Whether or not integrated with an exterior rearview mirror, the exterior display and / or camera lens can take the aforementioned positions via other exterior vision units. The exterior display and / or camera lens can then be positioned, for example, in substantially the same location within the exterior vision unit as the exterior rearview mirror, but can also be positioned in other locations within the exterior vision unit.

[0005] The goal is to manufacture the vehicle's external vision unit with a compact design to minimize its contribution to the vehicle's overall aerodynamic drag. For example, digital external vision units, such as external cameras and / or external displays, can be manufactured in a particularly compact arrangement, thus the adjustment device increasingly determines the size of the external vision unit. However, a limiting factor in miniaturizing the adjustment device is that it must consistently possess sufficient robustness and resistance. For instance, adjustment devices typically include strong springs that continuously press the housing down onto the base, thereby defining the driving position in a persistent, vibration-free, and play-free manner. Additionally, the adjustment device needs to withstand impacts such as collisions or manual operation. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide a compact adjustment device while maintaining stability and resistance. To this end, the present invention provides an adjustment device for an external vision unit of a vehicle, comprising a base shaft and a housing surrounding the base shaft and pivotable about a longitudinal axis of the base shaft within an adjustment range at least between a parking position and a driving position. The adjustment device further includes a drive gear comprising a face and a gear body, the face being provided with external teeth surrounding the base shaft, the face defining a face height, and a web member of the gear body extending substantially between the base shaft and the face within the face height in a transverse plane relative to the base shaft. Furthermore, the adjustment device includes a spring surrounding the base shaft, the spring being supported on a support surface of the gear body for applying a spring force to the drive gear along the longitudinal axis. The support surface is recessed in the axial direction relative to the transverse plane such that the spring extends through the transverse plane, wherein the web member extends substantially in the transverse plane. Additionally or alternatively, the support surface is recessed in the axial direction relative to the transverse plane, such that the center of the spring lies within the surface height, wherein the web member extends substantially within the transverse plane. The center may, for example, be the center of gravity, center of mass, or geometric center of the spring. In particular, the center of the spring may at least substantially coincide with the center of the drive gear, providing a particularly stable assembly.

[0007] By providing a spring recessed within the drive gear, the axial dimensions of the adjusting device can be reduced while the spring geometry remains substantially unchanged. The spring, in particular, can maintain sufficient length in the axial direction, allowing the desired spring travel to be imparted to the spring with the desired number of turns in the case of a helical spring. Therefore, the spring can be manufactured with a sufficiently strong configuration, and its spring properties are largely preserved.

[0008] The face height indicates the dimensional range of a face's axial extension. For example, if a face extends axially between a bottom plane on its lower side and a top plane on its upper side, the face height can be limited between the bottom and top planes. Thus, the teeth of a gear can cover the entire face height, but this is not mandatory.

[0009] The supporting surface can be located within the surface height, such as within the axial range between the top and bottom planes. Specifically, the supporting surface can be recessed relative to the top plane, with the supporting surface closer to the bottom plane than to the top plane. More specifically, the supporting surface can be recessed relative to the top plane in the axial direction to a point more than half the surface height. Thus, the spring supported on the supporting surface extends through the top plane to a point more than half the surface height.

[0010] The web member of the gear body extends substantially laterally (i.e., in a plane transverse to the base axis), for example, between the central through-hole of the drive gear and the surface. Thus, in the transverse direction, the support surface lies between the central through-hole and the surface.

[0011] A spring may be disposed in a recessed portion within the gear body of the drive gear, wherein the bottom of the recessed portion defines the support surface. The inner wall of the recessed portion on the through-opening side may, for example, form a support surface surrounding the base shaft and providing support between the drive gear and the base shaft. A web member may protrude from the outer wall of the recessed portion on one side of the surface.

[0012] In addition, the gear body may, for example, be provided with at least a force transmission protrusion for engaging with the cam ring of the adjusting device.

[0013] The supporting surface of the drive gear that supports the spring is advantageously located outside the surface height, for example, below the surface height. In this case, the spring essentially passes through the drive gear to a point exceeding the axial dimension of the surface height, for example, passing through both the top and bottom planes. In this way, a particularly compact arrangement of the regulating device is achieved.

[0014] The drive gear may include a support surface surrounding the base shaft, wherein the height of the support surface is greater in the axial direction than the face height of the drive gear. This provides stable alignment of the drive gear about the base shaft. The support surface is formed, for example, by a recessed portion abutting against the base shaft.

[0015] Furthermore, the adjusting device advantageously includes two or more protruding rings surrounding the base shaft, each of the protruding rings being provided with at least one force-transmitting protrusion that can engage with a drive gear and / or a housing, wherein the two or more protruding rings are radially positioned relative to each other.

[0016] The supporting surface is preferably located between the base shaft and the convex ring.

[0017] In addition, the regulating device may include an electric motor connected to the housing and having an output shaft for pivoting the housing about a longitudinal axis of the base shaft, wherein the output shaft of the electric motor extends transversely to the longitudinal axis.

[0018] The ratio of the diameter of the base shaft to the diameter of the drive gear can be, for example, between 0.15 and 0.5.

[0019] The ratio of the shell's width to its height can, for example, be between 0.15 and 0.5. Thus, the shell's height is defined, for example, as the height along the longitudinal axis of the base shaft. Therefore, the shell's width is defined, for example, in a direction transverse to and intersecting the longitudinal axis of the base shaft.

[0020] The present invention also relates to an adjustment device for an external vision unit of a vehicle, comprising: a base shaft; and a housing surrounding the base shaft and pivotable about a longitudinal axis of the base shaft within an adjustment range at least between a parking position and a driving position; wherein the base shaft includes a receiving portion for receiving a screw within the base shaft. Thus, the adjustment device can be connected to the vehicle by means of a threaded connection. A threaded connection, for example, includes a single screw extending axially into the base shaft. In this way, the number of installation operations is minimized, and installation space is saved, allowing the adjustment device to be manufactured with a more compact design. The receiving portion can be formed by a cavity in the base shaft. Optionally, the inner wall of the base shaft is provided with an internal thread for engaging with the external thread of the screw. Obviously, the terms "screw" and "threaded connection" should be understood to include bolts, pins, and other rod-like or equivalent fasteners and related connections. In known adjustment devices, the base shaft typically has a hollow construction, allowing cables (e.g., cables for electrically adjusting mirror plates supported by a support frame) to pass through the hollow base shaft. The adjustment device is typically mounted on the vehicle's base component with three screws that pass through three holes distributed around the perimeter of the support legs along the base shaft. This provides an operationally reliable connection, but on the other hand, it requires a significant amount of assembly work and assembly components.

[0021] Advantageously, the adjustment device (particularly the base shaft) does not have cables for electrically adjusting external visual elements (e.g., rearview mirrors or cameras) supported by the support frame. The cables can be guided externally to the adjustment device, allowing for threaded connections via the base shaft. In this way, the adjustment device can be manufactured with a more compact arrangement. In particular, the diameter of the base shaft can be reduced, resulting in space savings in the radial or width direction of the adjustment device. The cables may additionally include data cables for establishing data connections between, for example, an external camera supported by the support frame and a display located inside the vehicle. In many cases, it is undesirable to guide the data cables through the base shaft, as sharp bends are thus imposed on the cables, leading to signal interference and signal loss. To avoid this, the data cables can then be arranged as straight as possible along the edges of the adjustment device.

[0022] The adjusting device may include one or more positioning protrusions and / or positioning recesses for engaging with one or more complementary positioning recesses and / or positioning protrusions of a base component of the vehicle on which the adjusting device may be mounted, to position the adjusting device relative to the base component. These positioning protrusions specifically ensure that the adjusting device is fixed relative to the base component on which the adjusting device is mounted, at least in the lateral and rotational directions.

[0023] Specifically, the adjusting device includes at least three positioning protrusions and / or positioning recesses. More specifically, the adjusting device includes cylindrical positioning protrusions or positioning recesses, positioning protrusions and / or positioning recesses elongated in the radial direction, and positioning protrusions or positioning recesses elongated in the circumferential direction.

[0024] The present invention also relates to an adjustment device for an external vision unit for a vehicle, comprising: a base shaft extending from a base along the longitudinal axis of the base shaft to a free end in an installed state; and a housing at least substantially surrounding the base shaft and pivotable about the longitudinal axis of the base shaft within an adjustment range at least between a parking position and a driving position; wherein the housing is mounted to the base shaft via a bearing at the free end of the base shaft.

[0025] Specifically, in the installed state, the base shaft extends from the base along the longitudinal axis of the base shaft to the open end, wherein the support member of the housing passes through the open end into the hollow base shaft to mount the housing around the base shaft via bearings on the inside of the base shaft.

[0026] The free end of the base shaft can be covered by a portion of the housing, such as a cover component of the housing. Therefore, the base shaft and spring are at least largely enclosed by the housing, resulting in a compact and easily installable regulating device. Furthermore, the internal components of the regulating device are isolated from the external environment by the housing.

[0027] The present invention also relates to an external vision unit for a vehicle, comprising an adjustment device and a rearview mirror, a display and / or a camera coupled to a housing.

[0028] It will be understood that each of the foregoing aspects, features, and options can be combined. It will also be understood that each of the features described with respect to one aspect of the invention applies equally to every other aspect of the invention. It will also be appreciated that all aspects, features, and options described with respect to the adjustment device apply equally to the external vision unit. Attached Figure Description

[0029] The invention will be further explained based on exemplary embodiments of the adjustment device shown in the accompanying drawings. In the drawings:

[0030] Figure 1 A schematic cross-section of the regulating device is shown;

[0031] Figure 2 An exploded perspective view of the regulating device is shown.

[0032] The accompanying drawings are shown by way of exemplary embodiments only and should not be regarded as limiting in any way. Detailed Implementation

[0033] Figure 1 and Figure 2 An adjustment device 1 for an external vision unit of a vehicle is shown. The adjustment device 1 includes a base shaft 2 extending along a longitudinal axis A and a housing 3. The housing 3 is composed of at least a first housing component 3a and a second housing component 3b connected to each other, for example, by means of screws 26a-26f. The housing 3 can pivot about the longitudinal axis A of the base shaft 2 within an adjustment range at least between a parking position and a driving position. Optionally, it can also pivot further from the driving position to a folded position, in which the support frame is positioned substantially along the edge of the vehicle, and in the case of an external rearview mirror unit, the rearview mirror side faces away from the vehicle. The housing 1 is mounted on a base component 8 of the body of a motor vehicle (e.g., a sedan). The base shaft 2 is implemented here as a hollow shaft that extends from the support leg 7 of the base shaft 2 along the longitudinal axis A to a free open end 21. In the installed state, the base shaft extends at least substantially transversely to the support surface of the base component 8. The second housing component 3b forms a cover for the adjustment device 1, which covers the free end 21 of the base shaft 2. The adjustment device 1 is thus mainly enclosed by the housing 3. Spring 10 is located entirely within housing 3, for example. Additionally, base shaft 2 extends from leg 7 to free end 21 within housing 3.

[0034] Furthermore, the second housing component 3b includes a bearing component 22 that extends into the interior of the base shaft 2 through the open end 21 of the base shaft 2, wherein the bearing component 22 forms a support surface 23 that abuts against the inner wall of the hollow base shaft 2. This support of the housing 3 within the base shaft 2 is particularly stable and ensures particularly precise alignment of the housing 3 around the base shaft 2.

[0035] The adjusting device 1 also includes a drive gear 4 received within the housing 3, the drive gear 4 comprising a so-called face 5 and a gear body 20. The face 5 is provided with external teeth 6 surrounding the base shaft 2, and the face 5 defines a face height H, within which the web member 6 of the gear body 20 extends substantially between the base shaft 2 and the face 5 in a transverse plane relative to the base shaft. The drive gear 4 includes a central opening 9 through which the base shaft 2 is arranged.

[0036] Furthermore, the adjusting device 1 includes a spring 10, which is implemented here as a helical spring, surrounding the base shaft 2. The spring 10 is supported on the support surface 11 of the gear body 20 and applies a spring force to the drive gear along the longitudinal axis A. In the installed state of the adjusting device, the spring 10 is compressed between the support surface 11 on one side and the upper fastening ring 12 (implemented here as a positioning ring) on ​​the other side. The first housing component 3a and the second housing component 3b are connected to each other by means of screws 26a-26f, so that the spring 10 is in a compressed state between the support surface 11 and the upper fastening ring 12.

[0037] The adjusting device 1 can be integrally mounted on the base component 8 using a single screw 24 that mates with the receiving portion of the hollow base shaft 2. The receiving portion is formed here by the base shaft 2 itself. The screw 24 is axially fitted into the hollow base shaft 2 such that the longitudinal direction of the screw 24 corresponds to the direction of the longitudinal axis A. The adjusting device 1 can be easily mounted on the base component 8 by inserting the screw 24 from below through an opening in the base component 8 and into the hollow base shaft 2, whereby the screw 24 engages with the internal thread of the base shaft 2 through its external thread, so that once the screw 24 is tightened, the base shaft 2 is pulled against the base component 8. A lower retaining ring 27 (here, a locating ring) is provided for connecting the base shaft 2 to the base ring 28 of the adjusting device 1, such that the base ring 28 is clamped onto the base component 8 of the vehicle by tightening the screw 24. In the installed state, the screw head 25 of the screw 24 then abuts against the base component 8 on the lower side of the adjusting device 1. Here, the base ring 28 and the base shaft 2 are rotated and locked by means of the triangular support 7 in the complementary receiving part of the base shaft 2 received in the base ring 28.

[0038] The base ring 28 also has three positioning recesses on the side facing the base component 8, which mate with three complementary positioning protrusions of the base component 8. The positioning protrusions and recesses provide for positioning and fixing the adjustment device 1 relative to the base component 8. Specifically, the positioning protrusions and recesses provide for fixing the adjustment device relative to the base component 8 on which the adjustment device 1 is mounted, at least in the lateral and rotational directions. The base ring 28 is made of plastic material, such that the positioning recesses in the base ring 28 can be pulled onto the corresponding complementary positioning protrusions of the base component 8 if the plastic base ring 28 is deformable. In fact, the base component 8 is typically made of a sintered material with relatively high hardness. Therefore, the base ring 28 made of plastic can accommodate dimensional tolerances between the positioning protrusions and recesses. Specifically, the base ring 28 includes a cylindrical positioning recess, a positioning recess elongated in the radial direction, and a positioning recess elongated in the circumferential direction; the base component 8 complementaryly includes a cylindrical positioning protrusion, a positioning protrusion elongated in the radial direction, and a positioning protrusion elongated in the circumferential direction.

[0039] The support surface 11 is recessed axially along the longitudinal axis A relative to the transverse plane (in which the web member 6 of the gear body 20 extends substantially). The center M of the spring 10 lies within the surface height H. In this case, the center M is the geometric center of the spring 10 in the installed state. In particular, the center M of the spring 10 is located at least substantially at the same position as the center N of the drive gear 4. The spring 10 here passes through the transverse plane in which the web member 6 extends substantially. In the illustrated configuration, the support surface 11 lies below the transverse plane. More specifically, the support surface 11 lies outside the surface height H, such that the spring 10 effectively passes through the drive gear 4, exceeding the surface height H, thereby achieving a compact and stable adjusting device 1. In particular, compared to conventional adjusting devices where the spring 10 is not arranged to be recessed in the drive gear 4 but supported on top of the web member 6 of the drive gear, a considerable reduction in the axial dimension of the adjusting device 1 can be achieved in this way. Furthermore, the reduction in axial dimension is achieved while the geometry of the spring 10 can remain substantially unchanged relative to conventional adjusting devices, thus allowing for a design with sufficient strength.

[0040] The drive gear 4 is provided with a recessed portion 13 that receives the spring 10, and the recessed portion 13 defines a support surface 11 on its bottom side. Additionally, a bearing ring 19 is arranged between the spring 10 and the support surface 11 to facilitate rotation of the drive gear 4 about the base shaft 2 relative to the spring 10. A support surface 14 is formed on the side of the recessed portion 13 adjacent to the base shaft 2. The support surface 14 surrounds the base shaft 2 and has a support height L greater than the surface height H of the surface 5, which provides stable guidance and alignment of the drive gear 4 about the base shaft 2.

[0041] The adjusting device 1 also includes two or more convex rings 15 surrounding the base shaft 2, each having at least one force-transmitting protrusion that can engage with the drive gear 4 and / or the housing 3. The convex rings 15 are radially positioned relative to each other, thereby achieving further space savings. More specifically, the convex rings 15 and the base shaft 2 define a mutual distance, wherein the support surface 11 is located between the convex rings 15 and the base shaft 2.

[0042] The regulating device 1 also includes a motor 16 connected to the housing 3 and having an output shaft 17 for pivoting the housing 3 about the longitudinal axis A of the base shaft 2. To minimize the height of the housing, the motor 16 is connected to the housing 3 in a flat configuration, wherein the output shaft 17 of the motor 16 extends transversely to the longitudinal axis A. The output shaft 17 is connected to the drive gear 4 via a transmission 18.
