Description

[0001] This application claims priority over Korean patent applications Nos. 10-2024-0165154, filed on November 19, 2024; 10-2024-0165184, filed on November 19, 2024; 10-2024-0192731, filed on December 20, 2024; 10-2025-0126638, filed on September 5, 2025; 10-2025-0126642, filed on September 5, 2025; and 10-2025-0126643, filed on September 5, 2025. The aforementioned applications are incorporated herein by reference in their entirety.

[0002] The present disclosure relates to a side mirror arrangement for a vehicle and in particular to a side mirror arrangement for a vehicle with an improved folding and tilting structure of a side mirror.

[0003] Generally, an interior rearview mirror is installed inside a vehicle so that the driver can more easily perceive the vehicle's rearward position, and exterior mirrors are installed on both sides of the vehicle's exterior so that the driver can see the vehicle's sides and rearward position. Through the field of vision provided by the interior or exterior mirrors, the driver can see surrounding vehicles or pedestrians and perform reversing, overtaking, and lane changes.

[0004] Recently, to reduce air resistance while driving and to decrease the likelihood of damage caused by external impacts, camera mirrors, including cameras, have been used instead of traditional side mirrors. Because images of the vehicle's surroundings, captured by the camera mirrors, are displayed on a screen inside the vehicle, the driver can easily see what is happening around the vehicle.

[0005] Meanwhile, while the vehicle is in motion, the side mirrors or camera mirrors are deployed so that the driver can see the vehicle's surroundings. However, when the vehicle is parked or navigating a confined space, it is necessary to fold the side mirrors or camera mirrors to the sides of the vehicle to prevent damage and to ensure visibility around the vehicle. In this case, the driver can rotate the side mirrors or camera mirrors manually or using actuators.

[0006] One objective of the present disclosure is to provide a side mirror arrangement for a vehicle with an improved folding and tilting structure of a side mirror.

[0007] The functions of the present disclosure are not limited to those mentioned above, and other functions not explicitly stated are clearly understood by the person skilled in the art on the basis of the following description.

[0018] The motor housing may further include a support element coupled to surround the cylindrical section, the support element being provided with a pair of support ends that support the tilting rotary unit along an axial direction of the second axis of rotation.

[0019] The support element may include a guide element that provides an alignment for coupling with the lower housing, and the cylindrical section may include on an outer circumferential surface thereof a projection configured to be received in the guide element and configured to engage with the support element during folding rotation.

[0020] The tilting and rotating unit may include: a base surface configured to be spaced apart from a base surface of the lower housing; a first support configured to support a first side of the base surface around the second axis of rotation; and a second support spaced apart from the first support along the axial direction of the second axis of rotation to support a second side of the base surface.

[0021] The first support may include support pieces spaced apart from each other along the second axis of rotation around the cylindrical section and arranged between the bottom surface of the lower housing and the pair of support ends.

[0022] The upper surfaces of the support ends and the lower surfaces of the support pieces can be designed as first curved surfaces, so that the support pieces can be rotated relative to the support ends about the second axis of rotation.

[0023] The lower housing may further include a support guide projecting from a side surface and arranged to overlap the support ends and the support pieces, and upper surfaces of the support pieces and a lower surface of the support guide may be designed as second curved surfaces so that the support pieces are rotatable about the second axis of rotation relative to the support guides.

[0024] First planes can be provided on both sides of the second curved surfaces of the support guide, and second planes can be provided on both sides of the second curved surfaces of the support pieces to selectively touch the first planes depending on a tilt direction of the tilting rotary unit.

[0025] The second support can be coupled so that the shaft extends into an interior thereof, and the inclined shaft mounting section can include an undercut-shaped mounting groove into which both end sections of the shaft extending into the interior of the second support are pressed and fixed.

[0026] The tilt-rotation unit may further include: a side wall extending from the base on both sides around the second axis of rotation and arranged to surround a side face of the lower housing. A groove may be provided on one side wall of the tilt-rotation unit or on the side face of the lower housing, and a projection may be provided on the other side wall of the tilt-rotation unit or on the side face of the lower housing to correspond to the groove. The groove and projection may be configured to selectively engage to limit the tilt-rotation range of the tilt-rotation unit to a predetermined area.

[0027] The side mirror assembly may further include a mounting module that elastically supports the motor housing on the mounting part, and the mounting module may include an auxiliary gear that provides a relative rotation to a first potentiometer configured to detect a rotation of the first drive unit.

[0028] The side mirror assembly may further include a control module that detects operating states of the first drive unit and the second drive unit, and the control module may include the first potentiometer, a second potentiometer configured to detect a rotation of the second drive unit, and a circuit board on which the first potentiometer and the second potentiometer are mounted.

[0029] According to one aspect of the present disclosure, a side mirror arrangement for a vehicle may comprise: a base with a first side connected to a vehicle and comprising a mounting part on a second side thereof with a folding pivot axis formed in a center of the mounting part; a motor housing comprising a lower housing and an upper housing, the motor housing being configured to rotate relative to the mounting part; a tilting rotary unit arranged in the motor housing and configured to rotate relative to the motor housing about a tilting pivot axis formed on a lower side of the motor housing; a second drive unit comprising a second motor that actuates a tilting rotation of the tilting rotary unit with respect to the motor housing;A coupling unit configured to transmit a rotational force from the second drive unit to the tilt rotation unit about the tilt rotation axis and to prevent the transmission of a rotational force from the tilt rotation unit to the second drive unit; a mirror housing comprising a reflector, the mirror housing containing the motor housing; and a mounting frame coupled to the mirror housing and the tilt rotation unit. The mirror housing comprising the reflector, the tilt rotation unit, and the mounting frame can rotate together in a tilting direction or in a folding direction.

[0030] The coupling unit may comprise: a third worm gear arranged to engage with the second drive unit and mounted on a shaft provided along the tilting axis of rotation; a coupling wheel mounted on the shaft next to the third worm gear; and a coupling spring positioned between the third worm gear and the coupling wheel to selectively transmit a rotational force.

[0031] The third worm gear may comprise: a rotating body arranged to surround the shaft; and a third gear section projecting outwards from one end of the rotating body and having an outer circumferential surface engaging with the second drive unit, and an insertion groove formed on an inside of the third gear section near the third gear section and the rotating body to allow one side of the coupling gear to be inserted therein.

[0032] The coupling gear may comprise: a fourth gear section formed on an outer circumferential surface of the coupling gear; an insertion body projecting from one side of the fourth gear section and configured to be inserted into the insertion groove; and a projection extending radially inward along the tilting axis of rotation within the fourth gear section and the insertion body. The side mirror assembly may further comprise a tilting worm gear provided in the tilting rotary unit and configured to receive a rotational force from the coupling unit in order to transmit a tilting rotational force to the tilting rotary unit.

[0033] The tilt worm gear may include: a fifth gear section on its upper side, configured to provide tilt rotation information to a second potentiometer; and a sixth gear section on its lower side, configured to mesh with the fourth gear section. A shaft hole, through which the shaft is coupled, may be formed beneath the sixth gear section.

[0034] The shaft hole can be designed as an elongated slot so that when the fourth and sixth gear sections engage and rotate, the inclined worm gear can be rotated around the inclined axis of rotation.

[0035] The clutch spring can include an opening that is open on one side along the tilting axis of rotation and is coupled to the rotating body so that inside the clutch wheel the opening corresponds to the protruding piece.

[0036] A rotational force from the second drive unit can be transmitted successively through the third worm gear, the clutch spring, and the clutch wheel to the tilting worm gear. Conversely, if an external force is applied to the tilting rotary unit, the external force can be transmitted successively through the tilting worm gear, the clutch wheel, and the clutch spring to the clutch spring. This allows slippage between the clutch spring and the rotating body, thus preventing the transmission of the external force to the second drive unit via the third worm gear.

[0037] The tilt-rotation unit may comprise: the tilt worm gear, which provides a rotation amount for the second potentiometer; and a gear mounting section on which the third worm gear is installed to provide the tilt rotation of the tilt-rotation unit via the rotational force of the second drive unit, and the third worm gear may be configured to correspond to a rotation radius of the tilt-rotation unit and include gear teeth exposed within the lower housing and a body section that is located at least outside the gear teeth and is pressed and fixed to the tilt-rotation unit by the lower housing.

[0038] The lower housing may include: an exposure opening through which the third worm gear coupled to the tilting rotary unit is exposed within the lower housing; and a fixing section provided around the exposure opening to press an upper surface of the body section toward the gear mounting section when the gear teeth are inserted into the interior through the exposure opening.

[0039] The lower housing may comprise: a first installation section in which a first reduction gear is mounted to transmit a rotational force from a first motor; a second installation section in which a second reduction gear is mounted to transmit a rotational force between a second motor and the third worm gear; and a third installation section arranged between the first installation section and the second installation section, into which the respective ends of a first mounting section for the first motor and a second mounting section for the second motor are inserted and installed.

[0040] The side mirror assembly may further include a driven gear located in the motor housing and coupled to the mounting bracket and an auxiliary gear. The auxiliary gear may be configured either to rotate in contact with the driven gear or to be rotationally decoupled from the driven gear, allowing it to rotate relative to the driven gear. One of the driven gears or the auxiliary gear may include a recess, and the other may include a projection corresponding to the recess, so that when an external force is applied between the driven gear and the auxiliary gear, the driven gear can rotate relative to the auxiliary gear.

[0041] The lower housing can include at least one stop projecting from an inner base surface towards the driven gear, and the driven gear can include a stop groove into which the at least one stop can be inserted. Accordingly, an electric flip rotation can be performed within an angular range where the at least one stop and the stop groove interfere, and when an external force is applied, the driven gear and the auxiliary gear can be rotationally decoupled to allow a manual flip rotation while they rotate relative to each other.

[0042] The lower housing may include: a cylindrical section projecting from a bottom surface thereto to surround the fastening part; and a support guide arranged around the cylindrical section on one side of a lower surface of the lower housing and designed as a convex second curved surface.

[0043] The tilting rotary unit can include a pair of first support pieces spaced apart around the cylindrical section, each of the first support pieces having an upper surface designed as the second curved surface and arranged to be in surface contact with a lower surface of the support guide.

[0044] The side mirror arrangement may further include: a support element arranged around the cylindrical section, wherein the fastening part is arranged therein and includes support ends that project to be in surface contact with the undersides of the first support pieces, wherein the first support pieces and the support ends include contact surfaces that are designed as first curved surfaces and face each other.

[0045] The motor housing may include a motor installation unit comprising: on a first side thereof a first drive unit comprising a first motor to provide a folding rotation of the motor housing relative to the mounting part, and on a second side thereof a second drive unit comprising a second motor to provide a tilting rotation of the tilting rotation unit relative to the motor housing.

[0046] The aforementioned and other embodiments of the present disclosure offer the following advantages. First, since a mirror and a mirror housing are rotated together according to the folding or tilting operation, the framing line around the outer edge of the mirror can be minimized. Second, by simplifying the configuration of a first drive unit that folds the mirror housing and a second drive unit that tilts the mirror housing, costs can be reduced. Third, design freedom (e.g., design flexibility) can be ensured by optimizing components of a drive module and improving the mirror design. Fourth, during the assembly of a control module, the reference position of a first potentiometer or a second potentiometer can be corrected. Fifth, the ease of assembly of the control module can be improved.Sixth, the applicability to stop structures of different shapes and rotation ranges can be facilitated.

[0047] It is understood that the effects of the present revelation are not limited to those described above, and other effects of the present revelation will be evident from the following description.

[0057] The following sections describe embodiments in detail with reference to the accompanying drawings. Identical reference numerals denote identical or corresponding components, and repeated descriptions are omitted.

[0058] Fig. 1 is a top view illustrating a vehicle in which a side mirror arrangement for a vehicle according to an embodiment of the present disclosure is mounted, Fig. 2 is a top view illustrating a state in which the side mirror arrangement is in the Fig. 1. The illustrated vehicle is folded, and Fig. 3 is a perspective view that shows the in Fig. 2 illustrated side mirror arrangements.

[0059] With reference to Fig. 1, Fig. 2 to Fig. 3. A side mirror arrangement 100 for a vehicle 10 according to an embodiment of the present disclosure can correspond to a part of a side mirror that is installed on an outside of the vehicle 10.

[0060] The side mirror arrangement 100 can enable a driver to more easily check the field of vision of one side or the rear of the vehicle 10, which is reflected by a reflective part 120 provided in a mirror housing 110.

[0061] A base 11 can be provided on both sides of the vehicle 10, and a base cover 14, which covers the outside of the base 11, can be coupled to the base 11. The mirror housing 110 of the side mirror assembly 100 can rotate about a first axis of rotation RA1 (see Fig. 4) rotate, which is arranged vertically at the base 11 to perform a folding, or can rotate about a second axis of rotation RA2 (see Fig. 5) rotate, which is arranged horizontally, to perform a tilting action.

[0062] A drive device 200, which will be described later, can be provided within the side mirror assembly 100 to provide a driving force for a folding rotation or tilting rotation of the side mirror assembly 100 with respect to the base 11.

[0063] The base 11 can be located on the body or a door of the vehicle 10 and can support a relative rotation of the mirror housing 110. The base 11 can be made of a metal or a synthetic resin material to firmly support the side mirror assembly 100, and the outside of the base 11 can be provided with the base cover 14, which surrounds the base 11.

[0064] Additionally, the side mirror assembly 100 can generate a driving force through the drive device 200 to enable rotation of the mirror housing 110 relative to the base 11. The side mirror drive device 200 can be provided on the base 11 or within the mirror housing 110. In this embodiment, for example, the side mirror drive device 200 is provided within the mirror housing 110.

[0065] Fig. Figure 4 shows perspective views illustrating a state in which the in Fig. 3. The illustrated side mirror arrangement is folded. With reference to Fig. 4 The mirror housing 110 can be folded or unfolded in relation to the base 11.

[0066] The mirror housing 110, which is folded, may mean that, as in field (a) of Fig. Figure 4 illustrates that the mirror housing 110 is folded while rotating about the first axis of rotation RA1, so that an outer distal end of the mirror housing 110 or the reflective part 120 approaches a body 12 or a door 13 of the vehicle 10. For example, when the mirror housing 110 is folded, the overall width of the vehicle 10 can be reduced, thus securing the lateral space of the vehicle 10 to allow parking to be completed or to allow the vehicle 10 to pass through a narrow roadway.

[0067] The mirror housing 110, which is unfolded, may mean that, as in field (b) of Fig. Figure 4 illustrates that the mirror housing 110 is unfolded while it rotates, so that the outer distal end of the mirror housing 110 or the reflective part 120 moves away from the body 12 or the door 13 of the vehicle 10. That is, during the normal operation of the vehicle 10, the mirror housing 110 is unfolded to provide the driver with a reflected field of vision of the side and rear of the vehicle 10.

[0068] The base cover 14 can comprise a first cover 14a, which is arranged on the top of the base cover 14, and a second cover 14b, which is coupled on one side opposite the first cover 14a with respect to the base 11. The first and second covers 14a and 14b can be coupled to each other to surround the base 11.

[0069] In an area where the first and second covers 14a and 14b face each other, a lamp element 16 may be provided in some embodiments. This lamp element is formed over a predetermined area on the front or side of the base cover 14 and is selectively switched on. For example, the lamp element 16 may provide a side amplifier function. The lamp element 16 may also be provided on the rear of the base cover 14, mounted on a lower housing 111 or an upper housing 112, or mounted in a coupling area between the lower housing 111 and the upper housing 112. Additionally, an imaging device (e.g., a camera) for photographing the vehicle's surroundings 10 may be mounted on the base cover 14. For example, if the base cover 14 is provided with the camera, the camera may be mounted under the second cover 14b.

[0070] Fig. Figure 5 shows perspective views illustrating a state in which the in Fig. The illustrated side mirror arrangement is inclined. Referring to Fig. 5 The mirror housing 110 can be inclined within a predetermined angular range with respect to the base 11.

[0071] The mirror housing 110, which is inclined, can mean that the mirror housing 110 is rotated about the second axis of rotation RA2, which is arranged in a horizontal direction, from the one shown in field (a) of Fig. 5 illustrated state to that in field (b) of Fig. The mirror housing rotates in the illustrated state, thereby setting a vertical viewing angle. For example, a tilt rotation can be performed so that an upward or downward tilt of the mirror housing 110 facilitates securing a side and rear view at the driver's eye level, or a downward tilt can be performed automatically or selectively while parking or reversing to facilitate checking the curb or a parking line on a parking lot surface.

[0072] Fig. 6 and Fig. Seven separated perspective views are shown, which are in Fig. 3. Illustrating the side mirror arrangement in a disassembled state, and Fig. 8 is a sectional view showing the internal structure of the Fig. 3 illustrated side mirror arrangement.

[0073] With reference to Fig. 6, Fig. 7 to Fig. 8 The side mirror assembly 100 can comprise a mirror housing 110, a reflection part 120, a back plate 130, a bezel 140 and a drive device 200.

[0074] A base 11 can be made of metal, and a mounting part 17 can be provided on the other side (e.g., outer or distal side) of the base 11 so that the side mirror assembly 100 can be coupled. The mounting part 17 can be attached to the other end of the base 11 by three-point screw fastening or can be formed integrally with the base 11.

[0075] A mounting module 250 (see Fig. 10) The drive device 200 can be coupled to the mounting part 17, and the mirror housing 110 connected to the mounting module 250 can rotate about the first axis of rotation RA1, which is formed in the center of the mounting part 17.

[0076] The mirror housing 110 can comprise a lower housing 111 and an upper housing 112.

[0077] The lower housing 111 can be arranged to be rotatable relative to the fastening part 17, which is attached to the end of the base 11. An insertion section 14c can be provided on one side of the first cover 14a of the base cover 14 and the lower housing 111, and a connecting section 113 can be provided on the other. A through-hole 113a can be formed in the center of the connecting section 113 so that the fastening part 17 can be inserted.

[0078] The insertion section 14c can be formed integrally with the first cover 14a. Alternatively, the insertion section 14c can be configured as a separate part that can be attached to or removed from the first cover 14a and can be mounted in a coupling structure.

[0079] The first and second covers 14a and 14b are illustrated as positioned above and below each other by way of example, but can alternatively be positioned in a front-to-back (or left-to-right) direction with respect to Fig. 6. If the first and second covers 14a and 14b are arranged in the front-to-back direction, half-forms of the insertion section 14c may be provided in the first and second covers 14a and 14b respectively, so that an insertion section 14c is formed during assembly, or a complete insertion section 14c may be formed on either the first cover 14a or the second cover 14b.

[0080] The connecting section 113 can be formed on the lower housing 111 to project to the insertion section 14c, which is formed on the first cover 14a.

[0081] The insertion section 14c can be formed at a distal end of the first cover 14a to allow at least a portion of the connecting section 113, formed on the lower housing 111, to be inserted. The insertion section 14c and the connecting section 113 can be arranged to face each other, and at least the outer circumferential surface of the connecting section 113 can be formed as a first curved surface corresponding to the folding or tilting radius of the mirror housing 110.

[0082] A first sealing element 150 can additionally be provided between the insertion section 14c and the connection section 113. The first sealing element 150 can be configured to wrap around an inner circumferential surface of the insertion section 14c and can provide a seal between the insertion section 14c and the connection section 113. The first sealing element 150 can be coupled within the insertion section 14c from the underside of the first cover 14a in a direction in which the fastening part 17 projects.

[0083] The first sealing element 150 can comprise a first section 151 and a second section 152. The first section 151 can be arranged such that a corner surface 153 is located at one end of it, for example, an upper left corner surface. Fig. 8, in close contact with the outer circumferential surface (or the first curved surface) of the connecting section 113, and such that the other surface at one end thereof (or an upper right surface) is in contact with the inner circumferential surface of the insertion section 14c. The first sealing element 150 can be formed from a soft material. For example, the first sealing element 150 can be formed from a soft rubber, silicone, or the like. By contacting the inner circumferential surface of the insertion section 14c, the first sealing element 150 can prevent foreign bodies such as dust from entering the interior. The section element 152 can project from the other side surface of the first section 151 and can be supported on the inner circumferential surface of the insertion section 14c together with the first section 151.

[0084] A second sealing element 160 can additionally be provided below the first sealing element 150 between the insertion section 14c and the connection section 113. The second sealing element 160 can comprise a third section 161 and a fourth section 162. The second sealing element 160 can support the first sealing element 150 from below, so that the first sealing element 150 is positioned between the insertion section 14c and the connection section 113 or maintains close contact with the connection section 113.

[0085] The second sealing element 160 can be made of a stiffer material than the first sealing element 150. For example, the second sealing element 160 can be formed as a molded part made of rubber or a synthetic material that is relatively harder than the first sealing element 150.

[0086] The third section 161 can be provided within the first section 151 to face the first curved surface, which is the outer circumferential surface of the connecting section 113. The surface of the third section 161 facing the first curved surface of the connecting section 113 can be formed as a curved surface corresponding to the first curved surface.

[0087] The fourth section 162 can extend relative to the third section 161 and be angled to support the third section 161 from the base 11 (also: relative to the base 11). In this case, a fastening groove 163 can be formed on the upper surface of the fourth section 162 adjacent to the third section 161, which allows at least part of the other end of the first section 151 to be inserted into it.

[0088] The fastening groove 163 can be provided along the circumferential direction of the first sealing element 150 on the upper surface of the fourth section 162.

[0089] Accordingly, while supporting the first sealing element 150, the second sealing element 160 can prevent the first sealing element 150 from being removed from between the connecting section 113 and the insertion section 14c.

[0090] The first and second sealing elements 150 and 160 can be integrally formed by an overmolding process. In other words, the first and second sealing elements 150 and 160 can be integrally formed, and the corner surface 153 of the first sealing element 150, which is a soft component, comes into close contact with the connecting section 113 to prevent foreign matter from penetrating between the connecting section 113 and the base cover 14. When the first and second sealing elements 150 and 160 are configured as an integral body, the first sealing element 150 can be arranged to touch the connecting section 113, and the second sealing element 160 can be arranged to be spaced a predetermined distance from the connecting section 113 instead of directly touching it.

[0091] In some embodiments, the first section 151 of the first sealing element 150 and the third section 161 of the second sealing element 160 can each be provided with a first projection that extends toward the outer circumferential surface of the connecting section 113. The first projection can extend in one or more annular forms along the circumferential direction of the first or third section 151 or 161. That is, the first projection can induce line contact between the first curved surface of the connecting section 113 and the first or second sealing element 150 or 160.

[0092] Alternatively, the first section 151 of the first sealing element 150 and the third section 161 of the second sealing element 160 can each be provided with second projections that extend towards the outer circumferential surface of the connecting section 113. A plurality of second projections can extend in a predetermined dot pattern towards the first curved surface of the connecting section 113 to facilitate point contact.

[0093] The insertion section 14c and the connecting section 113 can limit the relative rotation of the mirror housing 110 within a predetermined angular range. Preferably, a lower section of the lower housing 111 can be designed adjacent to the connecting section 113 so as not to touch an upper end of the insertion section 14c.

[0094] Additionally, the upper housing 112 can be coupled to cover the top of the lower housing 111. A plurality of hooks 117 can be provided on an edge region of the upper housing 112, and engagement sections 116 with which the hooks 117 engage can be provided on an edge region of the lower housing 111, so that the upper housing 112 and the lower housing 111 can be fastened to one another by a snap-fit ​​method. Alternatively, the upper housing 112 and the lower housing 111 can be coupled by a coupling method using projections and grooves or by using screws. Accordingly, the drive device 200 of the side mirror assembly 100 can be installed in an internal receiving space 114 of the mirror housing 110 in a state in which the lower housing 111 and the upper housing 112 are coupled.

[0095] At an opening of the mirror housing 110 in a state in which the lower housing 111 and the upper housing 112 are coupled together, the back plate 130 and the reflection part 120 can first be coupled together and can then be coupled to the mirror housing 110.

[0096] A detailed description of the coupling relationship between the lower housing 111 and the base 11 by the drive device 200 of the side mirror assembly 100 will be provided later.

[0097] The reflective part 120 can be arranged between the lower housing 111 and the upper housing 112 and can project light reflected from the side or rear of the vehicle 10 towards the driver.

[0098] The backplate 130 can be arranged within the reflecting part 120 in the lower housing 111 or the upper housing 112 to closely support the rear surface of the reflecting part 120. The backplate 130 can be provided with a variety of engagement sections 121 to engage with hooks 115 provided along the perimeter of an opening defined by the upper housing 112 and the lower housing 111, so that the backplate 130 and the mirror housing 110 can be fastened by a snap-fit ​​connection method.

[0099] The back plate 130 can be fitted with a through hole 122 (see Fig. 7) be formed in which a lighting area is arranged so that, when the lane is changed, the area can light up depending on distance information from surrounding vehicles to provide assistance to the driver.

[0100] The reflective element 120 and the backplate 130 can be attached to each other using double-sided adhesive tape. Alternatively, the backplate 130 and the reflective element 120 can be attached to each other using other known fastening methods besides double-sided adhesive tape.

[0101] The bezel 140 can closely contact the distal end of the mirror housing 110 while surrounding a front outer edge of the reflecting part 120 and an outer edge region of the backplate 130. The bezel 140 can be attached to the front of the backplate 130 together with the reflecting part 120 in a snap-fit ​​connection.

[0102] Accordingly, the mirror housing 110, the reflection part 120, the back plate 130 and the bezel 140 can together rotate in a folding or tilting manner around the mounting part 17.

[0103] Fig. 9 is a perspective view illustrating a drive device for a side mirror arrangement for a vehicle according to a first embodiment of the present disclosure, Fig. 10. A splayed perspective view is what is in Fig. 9 illustrated drive device in a disassembled state, and Fig. 11 and Fig. These are 12 perspective views illustrating a state in which an engine housing of the in Fig. The drive device shown in section 10 has been removed for illustrative purposes.

[0104] With reference to Fig. 9, Fig. 10, Fig. 11 to Fig. 12. A side mirror arrangement 100 according to the first embodiment of the present disclosure may comprise a drive device 200 for a vehicle side mirror.

[0105] The drive device 200 can include the following: a motor housing 210, which is located inside a mirror housing 110 (see Fig. 6) is provided; a first drive unit 220, which is involved in a folding rotation of the mirror housing 110; a tilting rotation unit 230; a second drive unit 240, which is involved in a tilting rotation of the tilting rotation unit 230; and a mounting module 250 and a control module 270, which are provided on a mounting part 17.

[0106] First, the motor housing 210 can comprise a lower housing 211 and an upper housing 212. The lower housing 211 can be arranged inside the lower housing 111, and the motor housing 212 can be formed when the upper housing 212 is coupled to the upper side of the lower housing 211. In this case, although the motor housing 210 is arranged inside the mirror housing 110, it may not be coupled to the mirror housing 110, but only to the mounting part 17. For example, the first drive unit 220 can cause the folding rotation of the mirror housing 110 by causing a relative rotation of the motor housing 210 with respect to the mounting module 250 about a first axis of rotation RA1, which is located in the mounting part 17 (see Figure 1). Fig. 15) is designed to actuate. The second drive unit 240 can provide a relative rotation to the tilting rotary unit 230 about a second axis of rotation RA2, which is located between the motor housing 210 and the tilting rotary unit 230 (see Fig. 5) is designed, thereby providing a tilting drive for the mirror housing 110.

[0107] The first drive unit 220 can include a first motor 221 and a first gear module 222 and can enable rotation via the end output of the first gear module 222 in accordance with the rotation of the first motor 221. The first gear module 222 can include a first worm gear 223 and a first reduction gear 224. The first worm gear 223 can be coupled to the drive shaft of the first motor 221. The first worm gear 223 can transmit the rotational force to the first reduction gear 224. The first reduction gear 224 can mesh with the first worm gear 223, and the drive shaft of the first reduction gear 224 can be oriented in a direction different from that of the drive shaft of the first worm gear 223. The first reduction gear 224 can be configured with a variety of first gears 224a and a second gear 224b that provide a predetermined gear ratio and rotate together.Accordingly, the final output of the first gear module 222 can be supplied to the first reduction gear 224. A driven gear 251 of the mounting module 250 can mesh with the second gear 224b of the first reduction gear 224, and the motor housing 210 can rotate relative to the driven gear 251.

[0108] The tilt-rotation unit 230 can include a first cover 231, a second cover 232, and a third cover 233. The first cover 231 can be provided to cover the top of the upper housing 212. The second cover 232 can extend from one side of the first cover 231 to face a side surface of the lower housing 211. The third cover 233 can extend from the other side of the first cover 231 to face a side surface of the upper housing 212. In this case, one side surface of the lower housing 211 and one side surface of the upper housing 212 can be oriented in opposite directions with respect to the motor housing 210. The third cover 233 can be formed with a slot 234 that is curved along the radius of rotation of the tilt-rotation unit 230. A section of the second drive unit 240, which will be described later, can be mounted in the slot 234.

[0109] The first cover 231 can be coupled to the upper housing 212 or the lower housing 211. For example, as in Fig. As illustrated in Figure 9, the drive device 200 can further include a mounting frame 260 arranged between the tilting rotary unit 230 and an upper housing 112 to couple the tilting rotary unit 230 to the mirror housing 110. With a central portion of the mounting frame 260 attached to the top of the first cover 231 and an outer circumferential portion of the mounting frame 260 attached and fixed to the lower housing 111, the tilting rotary unit 230 can be arranged to tilt relative to the motor housing 210 together with the mirror housing 110.

[0110] The second drive unit 240 can include a second motor 241, a second gear module 242, a first shaft 243, and a second shaft 244. The second gear module 242 can include a second worm gear 245 and a second reduction gear 246. The second worm gear 245 can be coupled to the rotating shaft of the second motor 241. The second worm gear 245 can transmit a torque to the second reduction gear 246.

[0111] The second reduction gear 246 can mesh with the second worm gear 245, and the drive shaft of the second reduction gear 246 can be oriented in a direction different from that of the drive shaft of the second worm gear 245. The second reduction gear 246 can be configured with a variety of gears that provide a predetermined gear ratio and rotate together.

[0112] The second drive unit 240 can further include a third reduction gear 247, which meshes with the second reduction gear 246. In this case, the second and third reduction gears 246 and 247 can provide different gear ratios. The third reduction gear 247 can transmit the final output to the first shaft 243.

[0113] The mounting module 250 can elastically support the motor housing 210 on the mounting part 17. The mounting module 250 can include the driven gear 251, a clamping plate 252, a clamp 253, an elastic element 254, and an auxiliary gear 255.

[0114] The driven gear 251 can be fixed in the motor housing 210, such that the mounting part 17 extends into the interior of the driven gear 251. Because the driven gear 251 is coupled and fixed to the mounting part 17, the driven gear 251 does not rotate, but the rotational force transmitted from the first reduction gear 224 to the driven gear 251 can cause the motor housing 210 to rotate relative to the driven gear 251, thus generating the pivoting rotation. That is, the driven gear 251 can be fixed with respect to the mounting part 17, and the first reduction gear 224 can rotate while remaining engaged with the driven gear 251.

[0115] The clamping plate 252 can be attached to a distal end of the mounting part 17 by the clamp 253. The elastic element 254 can provide an elastic support between the driven gear 251 and the clamping plate 252.

[0116] The secondary gear 255 can be provided to surround the outside of the elastic element 254 and can be placed on the driven gear 251 to be rotatable with the driven gear 251. Gear teeth can be formed on the outer circumferential surface of the secondary gear 255 to engage with a section of the control module 270, which will be described later, and the state of the folding rotation of the motor housing 210 with respect to the secondary gear 255 can be transmitted to the control module 270.

[0117] The control module 270 can include a circuit board 271, a first potentiometer 272 that detects a rotation of the first drive unit 220, and a second potentiometer 273 that detects a rotation of the second drive unit 240.

[0118] The first and second potentiometers 272 and 273 can each be mounted on the circuit board 271. Each of the first and second potentiometers 272 and 273 can be implemented by a variable resistor that converts a linear displacement or a rotational displacement into a change in electrical resistance. The first and second potentiometers 272 and 273 can be configured as contact or non-contact types. In this embodiment, the first and second potentiometers 272 and 273 are described, for example, as contact types. In a contact-type potentiometer, a brush moves on a resistive element so that a displacement can be measured according to a rotation angle or a number of rotations.

[0119] The first potentiometer 272 can be provided with a first gear 274, which is arranged so that it is rotatable on the circuit board 271, and the first gear 274 can mesh with gear teeth 256 of the secondary gear 255. Accordingly, the angle of the folding rotation of the motor housing 210 can be detected based on the rotation angle of the first gear 274 with respect to the gear teeth 256 of the secondary gear 255.

[0120] The second potentiometer 273 can be provided with a second gear 275, which is arranged to be rotatable on the circuit board 271, and the second gear 275 can engage with gear teeth formed on a tilting worm gear 249. Accordingly, the angle of tilt rotation of the tilting rotary unit 230 can be detected based on the angle of rotation of the second gear 275 according to the rotation of the tilting worm gear 249 about the first shaft 243.

[0121] Fig. 13 is a reference view showing a coupled position of the tilt rotation unit of the in Fig. 10 illustrated drive devices illustrated, and Fig. Figure 14 shows reference views illustrating a process in which the tilt-rotation unit of the drive device of the side mirror assembly of Fig. 10 is inclined.

[0122] With reference to Fig. 13 and Fig. 14 The first shaft 243 can penetrate a side surface of the lower housing 211 to transmit a rotational force for tilting rotation to the second cover 232.

[0123] A third worm gear 248 and the inclined worm gear 249 can be coupled to the first shaft 243 so that they can rotate together. The third worm gear 248 can mesh with the third reduction gear 247 and thereby transmit an output to the first shaft 243. The inclined worm gear 249 can be arranged to rotate in a limited manner within a predetermined angular range according to the rotation of the first shaft 243.

[0124] In this case, a distal end of the first shaft 243 can be coupled to the second cover 232, so that in response to the rotation of the first shaft 243, the tilting rotary unit 230 can rotate in a limited way within a predetermined angular range.

[0125] The second shaft 244 can penetrate a side surface of the upper housing 212 and be inserted into the slot 234 formed in the third cover 233. Accordingly, a rotation or movement of the tilting rotary unit 230 can be limited within a predetermined angular or length range based on the angle or length of the slot 234.

[0126] Fig. 15 and Fig. 16 reference views are shown, representing the folding or tilting states of the [unclear text]. Fig. 10 illustrated drive devices.

[0127] With reference to Fig. 15 and Fig. 16 can be the first axis of rotation RA1, around which the mirror housing 110 or the motor housing 210 is rotated onto the base 11 (see Fig. 8) is folded, be arranged on a virtual extension line of the second axis of rotation RA2, about which the tilting rotary unit 230 tilts. For example, the second axis of rotation RA2, which is formed at the center of rotation of the first shaft 243, can be arranged to intersect the first axis of rotation RA1 in an axial direction.

[0128] This means that the motor housing 210 and the mirror housing 110 can rotate to be folded together around the first axis of rotation RA1, which is the center of rotation of the mounting part 17. Since the second axis of rotation RA2 lies in the motor housing 210, the mirror housing 110 can rotate to be tilted together with the tilting rotary unit 230 within a predetermined angular range relative to the motor housing 210.

[0129] Furthermore, by designing the gear ratio of the first gear module 222 during folding rotation and the gear ratio of the second gear module 242 during tilting rotation to be at the same level, a perceived mismatch between folding and tilting speeds can be prevented. For example, the gear ratio of the first gear module 222 can be 1500 to 1, and the gear ratio of the second gear module 242 can also be set to 1500 to 1, so that the start and end times of folding and tilting rotations become similar.

[0130] Accordingly, in the side mirror arrangement for a vehicle according to this embodiment, since the mirror and the mirror housing rotate together according to the folding or tilting operation, a framing line on the outer edge of the mirror can be minimized, costs can be reduced by simplifying configurations of the first drive unit for folding the mirror housing and the second drive unit for tilting the mirror housing, and design flexibility can be improved by improving the mirror design through optimization of components of the drive device.

[0131] Fig. 17 is a perspective view illustrating a drive device for a side mirror arrangement for a vehicle according to a second embodiment of the present disclosure, Fig. 18 is an expanded perspective view, which is in Fig. 17 illustrated drive device in a disassembled state, and Fig. 19 is a longitudinal cross-sectional view, which shows the in Fig. 17 illustrated drive devices are illustrated.

[0132] With reference to Fig. 17, Fig. 18 to Fig. 19 A side mirror arrangement 100 according to the second embodiment of the present disclosure may comprise a drive device 1200 for a vehicle side mirror.

[0133] The drive device 1200 can include the following: a motor housing 1210, which is inside a mirror housing 110 (see Fig. 6) is provided; a first drive unit 1220, which is involved in a folding rotation of the mirror housing 110; a tilting rotation unit 1230; a second drive unit 1240, which is involved in a tilting rotation of the tilting rotation unit 1230; and a mounting module 1250 and a control module 1270 (see Fig. 25), which are provided on a fastening part 17.

[0134] The motor housing 1210 can include a lower housing 1211 and an upper housing 1212.

[0135] The lower housing 1211 can be arranged within a lower housing 111, and an upper housing 1212 can be coupled to the upper side of the lower housing 1211, forming the motor housing 1210. In this case, although arranged within the mirror housing 110, the motor housing 1210 may not be coupled to the mirror housing 110, but only to the mounting part 17. For example, the first drive unit 1220 can cause a folding rotation of the mirror housing 110 to provide a relative rotation of the motor housing 1210 with respect to the mounting module 1250 about a first axis of rotation RA1, which is located at the mounting part 17 (see Figure 1). Fig. 25) is formed, and the second drive unit 1240 can provide a relative rotation to the tilting rotary unit 1230 about a second axis of rotation RA2, which is located between the motor housing 1210 and the tilting rotary unit 1230 (see Fig. 25) is formed, which causes the mirror housing 110 to tilt.

[0136] The lower housing 1211 can include a cylindrical section 1213 and a tilt shaft mounting section 1214. The cylindrical section 1213 can project downwards from one side of the lower housing 1211 and can be provided in a cylindrical shape to surround the mounting part 17 when the mounting part 17 is inserted in its center.

[0137] A support element 1215 can additionally be coupled around the cylindrical section 1213. Since the support element 1215 is coupled around the cylindrical section 1213, with a section of the tilting rotary unit 1230 arranged between the lower housing 1211 and the support element 1215, the support element 1215 can support one side of the tilting rotary unit 1230.

[0138] The support element 1215 can include guide elements 1216 that ensure correct alignment for coupling with the lower housing 1211. The guide elements 1216 can be configured as one or more projections and grooves facing the lower side of the lower housing 1211. In this embodiment, for example, one or more groove-like guide elements 1216 arranged along a single straight line can be provided on the upper surface of the support element 1215. One or more projections 1213a with a shape corresponding to the guide elements 1216 can be formed on the outer circumferential surface of the cylindrical section 1213 of the lower housing 1211. Accordingly, the guide elements 1216 can establish the coupling alignment of the support element 1215 with the lower housing 1211.Additionally, the guide elements 1216 and the projections 1213a can remain engaged with each other along a folding rotation direction, so that the support element 1215 and the cylindrical section 1213 rotate together when the motor housing 1210 performs a folding rotation.

[0139] The support element 1215 can also include a pair of support ends 1217 projecting towards the bottom surface of the lower housing 1211. The support ends 1217 can be spaced apart from each other along the axial direction of the second axis of rotation RA2 around the cylindrical section 1213 and can rotatably support one side of the tilting rotary unit 1230, which will be described later.

[0140] The support element 1215 can be provided to be rotatable relative to the fastening part 17 in a folding motion. In this case, a bushing 1218 can additionally be provided in an area where the support element 1215 and the fastening part 17 are in contact with each other.

[0141] The tilt shaft mounting section 1214 can support the other side of the tilt rotation unit 1230 on the other side of the lower housing 1211. The tilt shaft mounting section 1214 can accommodate a shaft 1243 provided on the axis of rotation of the lower housing 1211, i.e., the second axis of rotation RA2, and the tilt rotation unit 1230 can be attached to the shaft 1243 to be rotatable about the second axis of rotation RA2.

[0142] The tilting rotary unit 1230 can be arranged to rotate relative to the motor housing 1210 about the second axis of rotation RA2 (i.e., the tilting axis of rotation), which is formed at a lower center of the motor housing 1210. The tilting rotary unit 1230 can rotate in a tilting direction by being driven by the second drive unit 1240. At this point, the tilting rotary unit 1230 can perform a tilting rotation about the second axis of rotation RA2 together with the mirror housing 110 and the reflector 120.

[0143] The tilting and rotating unit 1230 can include a base surface 1231, a first support 1232, a second support 1233, and a side wall 1234. The base surface 1231 can be positioned facing the base surface of the lower housing 1211 with a gap between them. The base surface 1231 and the lower housing 1211 can be spaced apart to allow relative rotation in conjunction with the tilting and rotating operation. The first and second supports 1232 and 1233 can be positioned on the base surface 1231 and spaced apart from each other. The first support 1232 can support one side of the base surface 1231 with respect to the second axis of rotation RA2, and the second support 1233 can support the other side of the base surface 1231 with respect to the second axis of rotation RA2.

[0144] The first support 1232 can include a pair of support pieces 1235 spaced apart from each other along the second axis of rotation RA2 with respect to the cylindrical section 1213. Each of the support pieces 1235 can be arranged on a respective support end 1217 of the support element 1215 in order to be in surface contact with it.

[0145] The side wall 1234 can be arranged to face both side surfaces of the lower housing 1211 and to surround the lower housing 1211. Accordingly, the tilting and rotating unit 1230 can be arranged to be tiltable about the second axis of rotation RA2 on the lower housing 1211.

[0146] The tilt-rotation unit 1230 can also be mounted inside the mirror housing 110 together with a mounting frame 1260. Although the tilt-rotation unit 1230 is only mounted on the lower housing 1211, with the mounting frame 1260 also being provided, the tilt-rotation unit 1230 can be rigidly attached to the upper housing 112 and the backplate 130 via the mounting frame 1260. The mounting frame 1260 can perform a tilt rotation about the second axis of rotation RA2 together with the mirror housing 110 and can rigidly support the structure in which the tilt-rotation unit 1230 rotates inside the mirror housing 110.

[0147] A detailed description of the mounting module 1250 and the control module 1270 will be provided later.

[0148] Fig. 20 and Fig. 21 perspective views illustrate a state in which the tilt-rotation unit of the in Fig. The drive device shown in 17 rotates. Fig. Figure 22 is a perspective side view illustrating a state in which the tilting rotary unit is in relation to the motor housing of the in Fig. The drive device shown in 17 rotates, and Fig. 23 is a reference view that shows a coupled state between the lower housing and the tilting rotary unit on the second support of the in Fig. 17 illustrated drive devices illustrated.

[0149] With reference to Fig. 20, Fig. 21, Fig. 22 to Fig. 23 The lower housing 1211 can include a support guide 1219 projecting from a side surface of the lower housing 1211. The support guide 1219 can be arranged to vertically overlap the support ends 1217 or the support pieces 1235. The lower surface of the support guide 1219 can be arranged to contact the upper surfaces of the support pieces 1235. In this case, the lower surface of the support guide 1219 and the upper surfaces of the support pieces 1235 can be designed as second curved surfaces to support relative rotation.

[0150] On the support guide 1219, first planes can be formed on both sides of the second curved surfaces facing the support pieces 1235. In this case, second planes selectively touching the first planes can be formed on the support pieces 1235. The second planes can be formed on both sides of the second curved surfaces of the support pieces 1235. Accordingly, if the first and second planes touch, the support guide 1219 and the support pieces 1235 can limit the rotation range of the tilting rotary unit 1230. The contact surfaces of the support pieces 1235 and support ends 1217 can be formed as first curved surfaces facing each other, thus implementing both a support structure and a fastening structure.

[0151] The second support 1233 can be spaced apart from the first support 1232 along the axial direction of the second axis of rotation RA2 to support the other side of the base surface 1231. The second support 1233 can be attached to the tilt shaft mounting section 1214, such that the shaft 1243, which is attached to the tilt shaft mounting section 1214, is arranged to extend into the interior of the second support 1233 and can also be connected to it to be able to perform the tilting rotation.

[0152] The tilting rotary unit 1230 can have grooves 1234a formed within the side wall 1234, and projections 1211a can be formed on the side surface of the lower housing 1211 facing the side wall 1234. Alternatively, projections can be formed within the side wall 1234, and grooves can be formed on the side surface of the lower housing 1211.

[0153] In this case, the projections 1211a and the grooves 1234a can be formed to correspond to each other so that they touch before the side wall 1234 and the side face of the lower housing 1211 touch, thereby limiting the range of relative rotation of the tilt-rotation unit 1230 with respect to the lower housing 1211. The projections 1211a and the grooves 1234a can be provided on both the lower housing 1211 and the tilt-rotation unit 1230 to limit the rotation range of the tilt-rotation unit 1230 in both directions.

[0154] The inclined shaft mounting section 1214 can be formed with an undercut-shaped mounting groove 1214a, so that both ends of the shaft 1243 are pressed and fixed. That is, the inclined shaft mounting section 1214 can be detachably coupled to the shaft 1243.

[0155] Fig. 24 is a reference view illustrating a state in which the upper casing of the in Fig. The drive device shown in 17 has been removed for illustrative purposes. Fig. 25 is an expanded perspective view showing the first drive unit and the second drive unit of the in Fig. 24 illustrated drive device illustrated, Fig. 26 is an enlarged perspective view showing the first drive unit of the in Fig. 24 illustrated drive device illustrated, and Fig. 27 is an enlarged perspective view showing the second drive unit of the in Fig. 25 illustrated drive devices illustrated.

[0156] The first drive unit 1220 can include a first motor 1221 and a first gear module 1222 and can enable a rotation via the end output of the first gear module 1222 according to the rotation of the first motor 1221.

[0157] The first gear module 1222 can include a first worm gear 1223 and a first reduction gear 1224. The first worm gear 1223 can be coupled to the drive shaft of the first motor 1221. The first worm gear 1223 can transmit a torque to the first reduction gear 1224.

[0158] The first reduction gear 1224 can mesh with the first worm gear 1223, and the rotating shaft of the first reduction gear 1224 can be oriented in a direction different from that of the rotating shaft of the first worm gear 1223. The first reduction gear 1224 can include a plurality of first gears 1224a and a second gear 1224b, which provide a predetermined gear ratio and rotate together.

[0159] Accordingly, the final output of the first gear module 1222 can be supplied to the first reduction gear 1224. A driven gear 1251 of the mounting module 1250 can mesh with the second gear 1224b of the first reduction gear 1224, and the motor housing 1210 can rotate relative to the driven gear 1251.

[0160] The second drive unit 1240 can include a second motor 1241, a second gear module 1242, and a shaft 1243. The second gear module 1242 can include a second worm gear 1245 and a second reduction gear 1246. The second worm gear 1245 can be coupled to the drive shaft of the second motor 1241. The second worm gear 1245 can transmit a torque to the second reduction gear 1246.

[0161] The second reduction gear 1246 can mesh with the second worm gear 1245, and the drive shaft of the second reduction gear 1246 can be oriented in a direction different from that of the drive shaft of the second worm gear 1245. The second reduction gear 1246 can include a plurality of gears that provide a predetermined gear ratio and rotate together.

[0162] The second drive unit 1240 can further include a third reduction gear 1247, which meshes with the second reduction gear 1246. In this case, the second and third reduction gears 1246 and 1247 can provide different gear ratios. The third reduction gear 1247 can transmit the final output to the shaft 1243, which is connected to a third worm gear 1248.

[0163] The mounting module 1250 can elastically support the motor housing 1210 on the mounting part 17. The mounting module 1250 can include the driven gear 1251, a clamping plate 1252, a clamp 1253, an elastic element 1254, and an auxiliary gear 1255.

[0164] The driven gear 1251 can be fixed in the motor housing 1210, such that the mounting part 17 extends into the interior of the driven gear 1251. Because the driven gear 1251 is coupled and fixed to the mounting part 17, rotation of the driven gear 1251 relative to the mounting part 17 can be prevented. However, the rotational force transmitted from the first reduction gear 224 to the driven gear 1251 can cause the motor housing 1210 to rotate relative to the driven gear 1251, thus producing a hinge rotation. That is, the driven gear 1251 can be fixed to the mounting part 17, and the first reduction gear 224 can rotate while remaining engaged with the driven gear 1251.

[0165] The clamping plate 1252 can be attached to a distal end of the mounting part 17 by the clamp 1253. The elastic element 1254 can provide an elastic support between the driven gear 1251 and the clamping plate 1252.

[0166] The secondary gear 1255 can be provided to surround the outside of the elastic element 1254 and can be placed on the driven gear 1251. Gear teeth can be formed on the outer circumferential surface of the secondary gear 1255 to engage with a section of the control module 1270, which will be described later, and the state of the folding rotation of the motor housing 1210 with respect to the secondary gear 1255 can be transmitted to the control module 1270.

[0167] The control module 1270 can include a circuit board 1271, a first potentiometer 1272 that detects a rotation of the first drive unit 1220, and a second potentiometer 1273 that detects a rotation of the second drive unit 1240.

[0168] The first and second potentiometers 1272 and 1273 can each be mounted on the circuit board 1271. Each of the first and second potentiometers 1272 and 1273 can be implemented by a variable resistor that converts a linear displacement or a rotational displacement into a change in electrical resistance. The first and second potentiometers 1272 and 1273 can be configured as contact or non-contact types. In this embodiment, the first and second potentiometers 1272 and 1273 are described, for example, as contact types. In a contact-type potentiometer, a brush moves on a resistive element so that a displacement can be measured according to an angle of rotation or a number of rotations.

[0169] The first potentiometer 1272 can be provided with a first gear 1274, which is arranged so that it is rotatable on the circuit board 1271, and the first gear 1274 can mesh with gear teeth 1256 of the secondary gear 1255. Accordingly, the angle of the folding rotation of the motor housing 1210 can be detected based on the rotation angle of the first gear 1274 relative to the gear teeth 1256 of the secondary gear 1255.

[0170] The second potentiometer 1273 can be provided with a second gear 1275, which is arranged to be rotatable on the circuit board 1271, and the second gear 1275 can engage with gear teeth formed on a tilting worm gear 1249. Accordingly, the angle of tilt rotation of the tilting rotary unit 1230 can be detected based on the angle of rotation of the second gear 1275 relative to a rotation of the tilting worm gear 1249 about the shaft 1243.

[0171] The shaft 1243 can be coupled to both the third worm gear 1248 and the inclined worm gear 1249 so that they can rotate together. The third worm gear 1248 can mesh with the third reduction gear 1247 and thereby transmit an output to the shaft 1243. The third worm gear 1248 and the inclined worm gear 1249 can be formed as an integral unit. The inclined worm gear 1249 can be arranged to rotate in a limited manner within a predetermined angular range according to the rotation of the shaft 1243.

[0172] According to the drive mechanism of this embodiment, configuring the first drive unit for tilting and the second drive unit for tilting as a single package allows for size reduction and cost reduction. Additionally, enclosing the drive mechanism provides greater freedom for improving the mirror design. Furthermore, the area over which the tilting / rotating unit performs a tilt rotation relative to the motor housing can be limited to a predefined range. Finally, improving the coupling structure of the tilting / rotating unit around the drive mechanism within the mirror housing provides a robust support structure for the tilt rotation.

[0173] Fig. 28 is a perspective view illustrating a drive device for a side mirror arrangement for a vehicle according to a third embodiment of the present disclosure, Fig. 29 is an expanded perspective view, which is in Fig. 28 illustrated drive device in a disassembled state, Fig. 30 is a longitudinal cross-sectional view showing an A-A' section of the in Fig. 28 illustrated drive device illustrated, and Fig. 31 is a longitudinal cross-sectional view showing a B-B' section of the in Fig. 28 illustrated drive device illustrated.

[0174] With reference to Fig. 28, Fig. 29, Fig. 30 to Fig. 31 A side mirror arrangement 100 according to the present disclosure may comprise a drive device 2200 for a vehicle side mirror.

[0175] The drive device 2200 can include the following: a motor housing 2210, which is inside a mirror housing 110 (see Fig. 6) is provided; a first drive unit 2220, which is involved in a folding rotation of the mirror housing 110; a tilting rotation unit 2230; a support element 2215; a second drive unit 2240, which is involved in a tilting rotation of the tilting rotation unit 2230; and a mounting module 2250, which is provided on a mounting part 17, a control module 2270 and a motor installation unit 2280.

[0176] The motor housing 2210 can include a lower housing 2211 and an upper housing 2212. The lower housing 2211 can be arranged inside a lower housing 111. The motor housing 2210 can be configured when the upper housing 2212 is coupled to the upper side of the lower housing 2211. In this case, although the motor housing 2210 is arranged inside the mirror housing 110, it may not be coupled to the mirror housing 110, but only to the mounting part 17.For example, the first drive unit 2220 can drive a folding rotation of the mirror housing 110 to provide a relative rotation of the motor housing 2210 with respect to the mounting module 2250 about a first axis of rotation RA1 formed on the mounting part 17, and the second drive unit 2240 can drive a tilting rotation of the tilting rotation unit 2230 about a second axis of rotation RA2 formed between the motor housing 2210 and the tilting rotation unit 2230 to provide a relative rotation of the mirror housing 110.

[0177] The lower housing 2211 can include a cylindrical section 2213, a tilt shaft mounting section 2214, a first mounting section 2218a, a second mounting section 2218b and a third mounting section 2218c.

[0178] The cylindrical section 2213 can project downwards from one side of the bottom surface of the lower housing 2211 and can be formed in a hollow cylindrical shape to surround the fastening part 17 when the fastening part 17 is inserted in its center.

[0179] A first reduction gear 2224, which will be described later, can be mounted on the first assembly section 2218a, a second reduction gear 2246 can be mounted on the second assembly section 2218b, and a motor installation unit 2280 can be mounted on the third assembly section 2218c. The first, second, and third assembly sections 2218a, 2218b, and 2218c can be formed within the lower housing 2211, thus facilitating the assembly of the first reduction gear 2224, the second reduction gear 2246, a third reduction gear 2247, and the motor installation unit 2280.

[0180] The support element 2215 can be additionally coupled around the cylindrical section 2213 via the fastening part 17. The support element 2215 can be fastened around the cylindrical section 2213 such that a section of the tilting rotary unit 2230 (or the first support pieces 2235) is arranged between the lower housing 2211 and the support element 2215, thereby supporting one side of the tilting rotary unit 2230.

[0181] The support element 2215 can include guide elements 2216 that ensure correct alignment for coupling with the lower housing 2211. The guide elements 2216 can be configured as one or more projections and grooves facing the lower side of the lower housing 2211. In this embodiment, for example, one or more groove-like guide elements 2216 can be provided in series on both sides of the support element 2215, facing each other. One or more first projections 2213a with a shape corresponding to the guide elements 2216 can be formed on the outer circumferential surface of the cylindrical section 2213 of the lower housing 2211. Accordingly, the guide elements 2216 can establish the coupling alignment of the support element 2215 with the lower housing 2211.Additionally, the guide elements 2216 and the first projections 2213a can engage with each other along the folding direction of rotation, so that the support element 2215 and the cylindrical section 2213 can rotate together when the motor housing 2210 folds.

[0182] The support element 2215 can further include a pair of support ends 2217 projecting towards the bottom surface of the lower housing 2211 (or towards the first support pieces 2235). The support ends 2217 can be arranged around the cylindrical section 2213 and spaced apart from each other along the axial direction of the second axis of rotation RA2 below the first support pieces 2235, and can rotatably support one side of the tilting rotary unit 2230, which will be described later.

[0183] During the folding rotation, the support element 2215 can be arranged to be rotatable on the mounting part 17. In this case, a bushing can additionally be provided in an area where the support element 2215 and the mounting part 17 contact each other.

[0184] The tilt shaft mounting section 2214 can support the other side of the tilt rotation unit 2230 on the other side of the lower housing 2211. A shaft 2243, arranged on the second axis of rotation RA2 of the lower housing 2211, can be attached to the tilt shaft mounting section 2214, and the tilt rotation unit 2230 can be coupled to the shaft 2243 to be rotatable about the second axis of rotation RA2.

[0185] The tilting rotary unit 2230 can be arranged to rotate relative to the motor housing 2210 about the second axis of rotation RA2 (i.e., the tilting axis of rotation), which is formed at a lower center of the motor housing 2210. The tilting rotary unit 2230 can rotate in a tilting direction by being driven by the second drive unit 2240. In this case, the tilting rotary unit 2230 can perform a tilting rotation about the second axis of rotation RA2 together with the mirror housing 110 and a reflector 120. The tilting rotary unit 2230 can have a base surface 2231, a first support 2232, a second support 2233 (see Fig. 34) and include a side wall 2234.

[0186] The base surface 2231 can be arranged to face the base surface of the lower housing 2211 with a gap between them. The base surface 2231 and the lower housing 2211 can be spaced apart from each other to allow relative rotation in conjunction with tilting rotation.

[0187] The first and second supports 2232 and 2233 can be arranged on opposite sides of the base surface 2231, spaced apart from each other. The first support 2232 can support one side of the base surface with respect to the second axis of rotation RA2, and the second support 2233 can support the other side of the base surface 2231 with respect to the second axis of rotation RA2.

[0188] The first support 2232 can include a pair of first support pieces 2235, which are spaced apart from each other along the second axis of rotation RA2 with respect to the cylindrical section 2213. Each of the first support pieces 2235 can be arranged on a respective support end 2217 of the support element 2215 to be in surface contact.

[0189] The side wall 2234 can be arranged to face both side surfaces of the lower housing 2211 and to surround the lower housing 2211. Accordingly, the tilting and rotating unit 2230 can be arranged to be tiltable about the second axis of rotation RA2 on the lower housing 2211.

[0190] Additionally, a tilting worm gear 2249 can be provided on the base 2231 of the tilting rotary unit 2230. The tilting worm gear 2249 can provide rotational data corresponding to a tilting rotation of the tilting rotary unit 2230 to a second potentiometer 2273, which will be described later.

[0191] The base surface 2231 of the tilting rotary unit 2230 can also be provided with a gear mounting section 2236 adjacent to the tilting worm gear 2249, in which a third worm gear 2248, described later, is installed. The gear mounting section 2236 can provide a mounting position so that a body section 2248a of the third worm gear 2248 can be at least partially inserted and fixed in a set position. When the third worm gear 2248 is mounted on the gear mounting section 2236, gear teeth formed on the top surface of the body section 2248a can be exposed.

[0192] Guide grooves 2230a for guiding a coupling position with the mirror housing 110 can be formed on the side wall 2234 of the tilting rotary unit 2230. The guide grooves 2230a can have a recess structure into which ribs 118 (see Fig. 6), which are provided on the lower housing 111, are inserted and can precisely guide the installation position of the tilt rotation unit 2230. The guide grooves 2230a and the ribs 118 allow for pre-assembly of the tilt rotation unit 2230 and the mirror housing 110, thereby improving ease of assembly.

[0193] The lower housing 2211 can be formed with a first opening 2214a through which the gear teeth of the third worm gear 2248, which is coupled to the tilting rotary unit 2230, are exposed into the interior of the lower housing 2211. As the gear teeth penetrate the interior of the lower housing through the first opening 2214a, a locking element 2214b can be provided around the first opening 2214a of the lower housing 2211 to press the upper surface of the body section 2248a or the outer circumference of the gear teeth toward the gear mounting section 2236. The locking element 2214b can rigidly support the third worm gear 2248 between the gear mounting section 2236 and the lower housing 2211 to prevent movement.

[0194] The tilt-rotation unit 2230 can also be mounted inside the mirror housing 110 together with a mounting frame 2260. Although the tilt-rotation unit 2230 is only mounted on the lower housing 2211, with the mounting frame 2260 also being provided, the tilt-rotation unit 2230 can be attached via the mounting frame 2260 to at least one of the upper housing 112 or the backplate 130. The mounting frame 2260 can perform a tilt rotation about the second axis of rotation RA2 together with the mirror housing 110 and can provide more secure support for the support structure in which the tilt-rotation unit 2230 rotates inside the mirror housing 110. The mounting frame 2260 can include hook elements 2261 and guide projections 2262.

[0195] When the tilting and rotating unit 2230 and the mounting frame 2260 are coupled together, the hook elements 2261 can be attached to the side wall 2234 of the tilting and rotating unit 2230, so that pre-assembly of the tilting and rotating unit 2230 and the mounting frame 2260 can be completed before they are attached to each other inside the mirror housing 110.

[0196] The guide projections 2262 can be inserted into the guide grooves 2230a. The guide projections 2262 can guide the coupling position of the tilting rotary unit 2230 to the mounting frame 2260. For example, the guide projections 2262 and the guide grooves 2230a can be arranged in different positions depending on whether the side mirror assembly 100 is for the left or right side mirror of a vehicle, thus preventing confusion between left and right side mirror parts and improving ease of assembly. The guide grooves 2230a can selectively accommodate the ribs 118 described above or the guide projections 2262, or a plurality of guide grooves can be formed in different positions to accommodate the ribs 118 or the guide projections 2262, respectively.

[0197] A detailed description of the mounting module 2250, the control module 2270 and the motor installation unit 2280 will be provided later.

[0198] Fig. 32 is a longitudinal cross-sectional view showing a B-B' section of the in Fig. 28 illustrated drive device illustrated, Fig. 33 is a perspective view illustrating a state in which the tilt rotation unit performs a tilt rotation relative to the motor housing of the in Fig. 28 illustrated drive device, and Fig. 34 is a reference view showing a coupled state between the lower housing and the tilting rotary unit on the second support of the in Fig. 28 illustrated drive device illustrated.

[0199] With reference to Fig. 32, Fig. 33 to Fig. 34 The lower housing 2211 can include a support guide 2219 projecting from a lower section of one side of the lower housing 2211. The support guide 2219 can be arranged to vertically overlap the support ends 2217 or the first support pieces 2235. The lower surface of the support guide 2219 can be arranged to be in surface contact with the upper surfaces of the first support pieces 2235. In this case, the lower surface of the support guide 2219 and the upper surfaces of the first support pieces 2235 can be designed as second curved surfaces to support a relative rotation (or tilt).

[0200] The contact surfaces of the first support pieces 2235 and the support ends 2217 can be formed as first curved surfaces facing each other, thereby implementing both a support structure and a fastening structure.

[0201] The second support 2233 can be spaced apart from the first support 2232 along the axial direction of the second axis of rotation RA2 to support the other side of the base surface 2231. The second support 2233 can be attached to the tilt shaft mounting section 2214, so that a shaft 2243, attached to the tilt shaft mounting section 2214, can be arranged to extend into the interior of the second support 2233 and can also be connected to allow tilt rotation.

[0202] The tilt-rotation unit 2230 can have second projections 2234a formed on the inside of the side wall 2234. The second projections 2234a can contact the side surface of the lower housing 2211 when the tilt-rotation unit 2230 is tilting and rotating. Alternatively, the second projections 2234a can be formed on the outside of the lower housing 2211. In this case, the second projections 2234a can limit the range of relative rotation of the tilt-rotation unit 2230 with respect to the lower housing 2211.

[0203] Fig. Figure 35 is a reference view illustrating a state in which an upper housing of the in Fig. The drive device shown in section 28 is removed. Fig. 36 is an expanded perspective view showing the first and second drive units of the in Fig. 35 illustrated drive device illustrated, Fig. 37 is an enlarged perspective view showing the first drive unit of the in Fig. 36 illustrated drive device illustrated, Fig. Figure 38 is an enlarged perspective view showing the second drive unit of the in Fig. 36 illustrated drive device illustrated, and Fig. 39 is a perspective view showing the coupling between a secondary gear and a driven gear of the in Fig. 36 illustrated drive devices.

[0204] With reference to Fig. 35, Fig. 36, Fig. 37, Fig. 38 to Fig. 39 The first drive unit 2220 can include a first motor 2221 and a first gear module 2222. In response to the rotation of the first motor 2221, the first drive unit 2220 can enable a folding rotation via the end output of the first gear module 2222.

[0205] The first gear module 2222 can include a first worm gear 2223 and a first reduction gear 2224. The first worm gear 2223 can be coupled to the drive shaft of the first motor 2221. The first worm gear 2223 can transmit a torque to the first reduction gear 2224.

[0206] The first reduction gear 2224 can mesh with the first worm gear 2223, and the rotating shaft of the first reduction gear 2224 can be oriented in a direction different from that of the rotating shaft of the first worm gear 2223. The first reduction gear 2224 can include a first gear 2224a and a second gear 2224b, which provide a predetermined gear ratio and rotate together.

[0207] Accordingly, the final output of the first gear module 2222 can be supplied to the first reduction gear 2224. A driven gear 2251 of the mounting module 2250 can mesh with the second gear 2224b of the first reduction gear 2224, and the motor housing 2210 can rotate relative to the driven gear 2251, so that a folding rotation occurs.

[0208] The second drive unit 2240 can include a second motor 2241, a second gear module 2242, and a shaft 2243. The second gear module 2242 can include a second worm gear 2245 and a second reduction gear 2246. The second worm gear 2245 can be coupled to the drive shaft of the second motor 2241. The second worm gear 2245 can transmit a torque to the second reduction gear 2246.

[0209] The second reduction gear 2246 can mesh with the second worm gear 2245, and the drive shaft of the second reduction gear 2246 can be oriented in a direction different from that of the drive shaft of the second worm gear 2245. The second reduction gear 2246 can include a plurality of gears that provide a predetermined gear ratio and rotate together.

[0210] The second drive unit 2240 can further include a third reduction gear 2247 that meshes with the second reduction gear 2246. In this case, the second and third reduction gears 2246 and 2247 can provide different gear ratios. The third reduction gear 2247 can supply the final output to a third worm gear 2248 to tilt and rotate the tilting rotary unit 2230.

[0211] The mounting module 2250 can elastically support the motor housing 2210 on the mounting part 17. The mounting module 2250 can include the driven gear 2251, a clamping plate 2252, a clamp 2253, an elastic element 2254, and an auxiliary gear 2255.

[0212] The driven gear 2251 can be arranged in the motor housing 210 (see Fig. 29), so that the mounting part 17 can extend into the interior of the driven gear 2251. Although the driven gear 2251 is coupled and fixed to the mounting part 17 and therefore does not rotate with respect to the mounting part 17, the rotational force transmitted from the first reduction gear 2224 to the driven gear 2251 can cause the motor housing 2210 to rotate relative to the driven gear 2251, thus producing a hinge rotation. That is, the driven gear 2251 can be fixed to the mounting part 17, and the first reduction gear 2224 can rotate while remaining engaged with the driven gear 2251.

[0213] The clamping plate 2252 can be coupled to a distal end of the fastening part 17 by the clamp 2253. The clamping plate 2252 can be provided with a stepped section 252a that surrounds the clamp 2253 to prevent the clamp 2253 from being removed after it has been coupled to the fastening part 17.

[0214] The clamp 2253 can be coupled along a first fastening groove 17a formed at the distal end of the fastening part 17. In this case, a second fastening groove 17b can be formed at a position on the distal end of the fastening part 17 where the first fastening groove 17a is not formed. A fastening projection 2253a, extending from a central region of the clamp 2253, can be inserted into the second fastening groove 17b. Accordingly, when the fastening projection 2253a is inserted into the second fastening groove 17b, it prevents the clamp 2253 from rotating about the first axis of rotation RA1 at the distal end of the fastening part 17.

[0215] The elastic element 2254 can provide an elastic support between the secondary gear 2255 and the clamping plate 2252. That is, the elastic element 2254 can provide an elastic restoring force so that when the position of the clamping plate 2252 is fixed by the clamp 2253, the secondary gear 2255 is pressed (e.g., preloaded) against the driven gear 2251.

[0216] The secondary gear 2255 can be arranged to surround the outside of the elastic element 2254 and can be placed on the driven gear 2251. Gear teeth 2256 can be formed on the outer circumferential surface of the secondary gear 2255 to engage with a section of the control module 2270, which will be described later, and the state of the folding rotation of the motor housing 2210 with respect to the secondary gear 2255 can be transmitted to the control module 2270.

[0217] The control module 2270 can include a circuit board 2271, a first potentiometer 2272 that detects a rotation of the first drive unit 2220, and a second potentiometer 2273 that detects a rotation of the second drive unit 2240.

[0218] The first and second potentiometers 2272 and 2273 can each be mounted on the circuit board 2271. Each of the first and second potentiometers 2272 and 2273 can be implemented by a variable resistor that converts a linear displacement or a rotational displacement into a change in electrical resistance. The first and second potentiometers 2272 and 2273 can be configured as contact or non-contact types. In this embodiment, the first and second potentiometers 2272 and 2273 are described, for example, as contact types. In a contact-type potentiometer, a brush moves on a resistive element, so that a displacement can be measured based on a rotation angle or a number of rotations.

[0219] The first potentiometer 2272 can be provided with a first gear 2274, which is arranged so that it is rotatable on the circuit board 2271, and the first gear 2274 can mesh with gear teeth 2256 of the secondary gear 2255. Accordingly, the tilting rotation angle of the motor housing 2210 can be detected based on the rotation angle of the first gear 2274 relative to the gear teeth 2256 of the secondary gear 2255.

[0220] The second potentiometer 2273 can be provided with a second gear 2275, which is arranged to be rotatable on the circuit board 2271, and the second gear 2275 can engage with gear teeth formed on the tilting worm gear 2249. Accordingly, the tilting rotation angle of the tilting rotary unit 2230 can be detected based on the rotation angle of the second gear 2275 relative to a rotation of the tilting worm gear 2249 about the shaft 2243. The tilting worm gear 2249 can rotate in a limited manner within a predetermined angular range corresponding to the tilting rotation range of the tilting rotary unit 2230.

[0221] The motor installation unit 2280 can include a first mounting section 2281, a second mounting section 2282, and a third mounting section 2283. The first mounting section 2281 can be an area located on one side of the motor installation unit 2280 where the first motor 2221 is configured to be mounted; the second mounting section 2282 can be an area located on the other side where the second motor 2241 is configured to be mounted; and the third mounting section 2283 can be an area located between the first and second mounting sections 2281 and 2282 where the circuit board 2271 is mounted.

[0222] In the motor installation unit 2280, the first and second assembly sections 2281 and 2282 can be configured to correspond to the dimensions of the first and second motors 2221 and 2241, respectively, and they can be of different sizes. In this embodiment, the first assembly section 2281 is illustrated by way of example as being larger than the second assembly section 2282.

[0223] The third mounting section 2283 can be configured as a slot, allowing for easy mounting and removal of the circuit board 2271. Since the circuit board 2271 can be slid into or out of the third mounting section 2283, improved mountability of the circuit board 2271 can be expected. The third mounting section 2283 can provide a structure that connects the first and second mounting sections 2281 and 2282.

[0224] After the first and second motors 2221 and 2241 are mounted on the first and second mounting sections 2281 and 2282 of the motor installation unit 2280, the motor installation unit 2280 can be installed inside the motor housing 2210 (see Fig. 28). The rotating shafts of the first and second motors 2221 and 2241 can be arranged parallel along a direction in which the motor installation unit 2280 is coupled to the lower housing 2211. For example, the rotating shafts of the first and second motors 2221 and 2241 can be arranged parallel to the hinged axis of rotation of the motor housing 2210, i.e., the first axis of rotation RA1. Alternatively, the rotating shafts of the first and second motors 2221 and 2241 can be arranged to form a predetermined angle with the first axis of rotation RA1.By installing the motor installation unit 2280 so that the rotating shafts of the first and second motors 2221 and 2241 are generally aligned perpendicular to the bottom surface of the lower housing 2211, the required installation space can be significantly reduced compared to a structure in which the rotating shafts of the first and second motors 2221 and 2241 are arranged horizontally with respect to the bottom surface of the lower housing 2211.

[0225] A lower end 2281a of the first assembly section 2281 and a lower end 2282a of the second assembly section 2282 can be fixed, with at least sections thereof being inserted into the third assembly section 2218c of the lower housing 2211. When the motor installation unit 2280 is inserted and installed in the third assembly section 2218c, a first worm gear 2223, coupled to the rotating shaft of the first motor 2221, and a second worm gear 2245, coupled to the rotating shaft of the second motor 2241, can be arranged to mesh with the first reduction gear 2224 and a third reduction gear 2247, respectively. The lower housing 2211 can also be provided with a fourth assembly section 2218d in which the second reduction gear 2246 is installed between the second worm gear 2245 and the third reduction gear 2247.

[0226] When an external force is applied to the mirror housing 110 while the first motor 2221 is at rest, the driven gear 2251 can undergo a relative rotation with respect to the secondary gear 2255 about the first axis of rotation RA1 on the mounting part 17. This relative rotation can provide a configuration that allows manual rotation to prevent damage between the first drive unit 2220 and the driven gear 2251, even if the mirror housing 110 is forcibly rotated by an external force.

[0227] Recesses 2251a can be formed on one of the driven gear 2251 or the auxiliary gear 2255, and third projections 2255a corresponding to the recesses 2251a can be provided on the other. In this embodiment, the recesses 2251a can be formed on the top of the driven gear 2251, and the third projections 2255a can be provided on the bottom of the auxiliary gear 2255. The recesses 2251a and the third projections 2255a can be configured to contact each other along inclined surfaces in the folding direction. Accordingly, when an external force greater than a predetermined threshold is applied, the third projections 2255a can lift the inclined surfaces of the respective recesses 2251a and be ejected from them. A multitude of recesses 2251a and a multitude of third projections 2255a can be provided on the driven gear 2251 or .the secondary gear 2255 is arranged over a predetermined angular range.

[0228] Since the elastic element 2254 of the mounting module 2250 biases the secondary gear 2255 towards the driven gear 2251, the recesses 2251a and the third projections 2255a can remain engaged when a folding rotation is performed electrically via the drive device 200. Here, when the first motor 2221 is at rest and the mirror housing 110 is rotated in the folding direction by an external force, the first drive unit 2220 and the driven gear 2251 can rotate together about the first axis of rotation RA1 on the mounting part 17, folding inwards while remaining engaged. Then, the engagement between the recesses 2251a and the third projections 2255a can be released, allowing the driven gear 2251 and the secondary gear 2255 to be separated.Since several recesses 2251a and several third projections 2255a are arranged along the folding direction of rotation, once a third projection 2255a is ejected from a corresponding recess 2251a, manual rotation can be continued until the third projection 2255a is inserted into an adjacent recess 2251a.

[0229] Fig. 40 is a perspective view showing another embodiment of the lower housing and the driven gear of the in Fig. 29 illustrated drive device illustrated, and Fig. Figure 41 is a partially cutaway perspective view showing the lower housing and the driven gear of the in Fig. 40 illustrated drive devices are illustrated.

[0230] With reference to Fig. 40 and Fig. 41 The lower housing 2211 can include stops 2211b projecting from an inner bottom surface 2211a of the lower housing 2211 around the cylindrical section 2213. A plurality of stops 2211b can be provided opposite each other around the center of the cylindrical section 2213. A pair of stops 2211b can form a unit stop, and a plurality of unit stops can be arranged in multiple regions. In this case, the stops 2211b can be arranged at the same radial distance from the center of the cylindrical section 2213. The distance (angle) between two adjacent unit stops can be uniform. Each unit stop (i.e., a pair of stops 2211b) can be implemented as a single integral body. For example, the single integral body can extend along the circumferential direction, which has a constant radial distance from the center of the cylindrical section 2213.

[0231] The stops 2211b can have an essentially rectangular prism shape. For example, the stops 2211b can limit the range of relative rotation with respect to the driven gear 2251.

[0232] The driven gear 2251 can include stop grooves 2251b on a surface facing the bottom surface 2211a of the lower housing 2211, formed in its circumferential direction. A plurality of stop grooves 2251b, corresponding to the number of unit stops, can be provided. The stop grooves 2251b can be arranged at equal intervals or within equal angular ranges.

[0233] An electrically driven folding rotation can be performed from a first position P1, in which a stop 2211b abuts one side of a stop groove 2251b, to a second position P2, in which another stop 2211b abuts the opposite side of the stop groove 2251b. The folding rotation range from the first position P1 to the second position P2 can correspond to the range of relative rotation between the lower housing 2211 and the driven gear 2251.

[0234] For example, if the lower housing 2211 rotates in one direction relative to the driven gear 2251 and an engagement occurs between the stops 2211b and the stop grooves 2251b, then, if a larger external force is applied in the same direction, the driven gear 2251 and the auxiliary gear 2255 may be separated from each other, allowing manual rotation to be initiated, as described above with reference to Fig. 39 described. Such a structure, in which an electrical rotation is limited, can be applied in areas where the folding / unfolding function of the side mirror assembly 100 is not actively used.

[0235] Accordingly, in the drive unit for the side mirror assembly of a vehicle according to this embodiment, mounting the first folding motor, the second tilting motor, and the circuit board on a single motor installation unit can improve ease of assembly and reduce the required installation space. Additionally, enclosing the drive unit can increase freedom for improving mirror design. Furthermore, unwanted movement of the third worm gear between the tilting rotation unit and the lower housing can be prevented. Moreover, when an external force is applied to the mirror housing, manual folding rotation is enabled, thus preventing damage to the first drive unit and the mounting module.

[0236] Fig. 42 is a perspective cross-sectional view, which shows a cross-section of the in Fig. 28 illustrated drive device illustrated, Fig. 43 is a cross-sectional view showing a C-C' section of the Fig. 42 illustrated drive device illustrated, Fig. 44 is a reference view, which shows a first potentiometer of the in Fig. 42 illustrated drive device illustrated, and Fig. Figure 45 is a reference view illustrating a process in which the first potentiometer of the in Fig. 44 illustrated drive device recorded a starting position.

[0237] With reference to Fig. 42, Fig. 43, Fig. 44 to Fig. 45 According to this embodiment, the control module 2270 of the drive device 2200 can set initial positions for the folding rotation and the tilting rotation by detecting the folding rotation of the motor housing 2210 and / or the tilting rotation of the tilting rotation unit 2230.

[0238] As described above, the control module 2270 can include the circuit board 2271, the first potentiometer 2272, which detects a rotation of the first drive unit 2220, and the second potentiometer 2273, which detects a rotation of the second drive unit 2240. Since the functions and operation of both the first and second potentiometers 2272 and 2273 are as described previously, redundant explanations are omitted, and the detailed structures of the first and second potentiometers 2272 and 2273 are described below.

[0239] The first and second potentiometers 2272 and 2273 can each be mounted on the circuit board 2271, and the circuit board 2271 can be detachably coupled to the third mounting section 2283 of the motor installation unit 2280.

[0240] The first potentiometer 2272 can include the first gear 2274 and a first position adjustment section 2276. The first gear 2274 can mesh with the gear teeth 2256 of the secondary gear 2255 and rotate relative to the secondary gear 2255 or rotate around it when the motor housing 2210 rotates about the first axis of rotation RA1 (see Fig. 30). With reference to Fig. 44 The first position adjustment section 2276 can be arranged within the first gear 2274. On the inner surface of the first gear 2274, a first tooth pattern 2274a of an internal gear type can be formed in a region facing the outer circumferential surface of the first position adjustment section 2276.

[0241] The first position adjustment section 2276 can be provided on the first gear 2274 coaxially with the axis of rotation of the first gear 2274, i.e., a third axis of rotation RA3. That is, the first position adjustment section 2276 can be arranged to be rotatable relative to the first gear 2274.

[0242] The first position-adjusting section 2276 can include a first rotor 2276a, a first contact section 2276b, first leg sections 2276c, and first contact pieces 2276d. The first rotor 2276a can be arranged to rotate about the same axis of rotation as the first gear 2274, i.e., the third axis of rotation RA3, and can be at least partially enclosed within the first gear 2274. Most of the exterior area of ​​the first rotor 2276a can be configured not to contact the first gear 2274. The first rotor 2276a can be configured as a generally circular plate, and the first contact section 2276b can be arranged adjacent to the third axis of rotation RA3.

[0243] The first contact section 2276b can project upwards from a central region of the upper surface of the first rotor 2276a. The first contact section 2276b can be arranged to contact a first stop 2284, which will be described later.

[0244] The first leg sections 2276c can be arranged on both sides of a cutout section along the circumferential direction of the first rotor 2276a. For example, the first leg sections 2276c can correspond to opposite sides of a break in a ring-like structure. Thus, a pair of first leg sections 2276c can be provided on respective sides of the cutout section and can be arranged to be elastically bent by the outer circumferential surface of the first rotor 2276a.

[0245] The first contact pieces 2276d can be provided at the distal ends of the respective first leg sections 2276c. The first contact pieces 2276d can project further from the outer circumferential surface of the first rotor 2276a to contact the first tooth pattern 2274a of the first gear 2274. Accordingly, when the first rotor 2276a rotates relative to the first gear 2274, the first contact pieces 2276d can elastically contact the first tooth pattern 2274a, and when the relative rotation stops, the first contact pieces 2276d can maintain the rotated state of the first rotor 2276a with respect to the first gear 2274.

[0246] The motor installation unit 2280 can include the first stopper 2284. The first stopper 2284 can be provided within the third assembly section 2283 of the motor installation unit 2280 (see Fig. 35).

[0247] The first stopper 2284 can be located within the rotation radius of the first contact section 2276b and can limit the relative rotation of the first rotor 2276a with respect to the first gear 2274 when the first contact section 2276b rotates. With reference to Fig. 45. The first stopper 2284 can have an essentially triangular profile and can include a first contact surface 2284a configured to bear against one face of the first contact section 2276b when the first rotor 2276a rotates in one direction, and a second contact surface 2284b configured to bear against the other face of the first rotor 2276a when the first rotor 2276a rotates in the opposite direction. The internal angle between the first and second contact surfaces 2284a and 2284b can be set to an acute angle. That is, the rotation range of the first contact section 2276b can be limited by the internal angle between the first and second contact surfaces 2284a and 2284b. Alternatively, the internal angle between the first and second contact surfaces 2284a and 2284b can be a right or obtuse angle.

[0248] The secondary gear 2255, which meshes with the first gear 2274, can be formed with chamfers 2255b. The chamfers 2255b can be formed at the front ends of the respective teeth of the secondary gear 2255, where the engagement with the first gear 2274 begins, so that the width of the teeth of the secondary gear 2255 is reduced towards the distal ends. Accordingly, meshing along the chamfers 2255b can be facilitated.

[0249] With reference to Fig. 44 The first contact section 2276b can be arranged to face a virtual first point P1 defined on the first gear 2274. That is, a virtual straight line L1 connecting the center of rotation of the first gear 2274 and the longitudinal center of the first contact section 2276b intersects the first point P1. The state in which the center of the first contact section 2276b and the first point P1 lie on the virtual straight line L1 is assumed to be a reference (base) position.

[0250] Unlike the one in Fig. 44. In the illustrated state, during the assembly of the first potentiometer 2272, the first gear 2274 and the first position adjustment section 2276 can be placed in a position that deviates from the reference position (i.e., does not hit the first point P1), as shown in Fig. Figure 45 illustrates this. In this case, a position correction can be performed to place the first gear 2274 and the first position adjustment section 2276 at the reference position after the assembly of the first potentiometer 2272 is complete.

[0251] For position correction, the first position adjustment section 2276 may need to be rotated relative to the first gear 2274, as shown in Fig. Figure 45 illustrates this. For example, when the first gear 2274 rotates in one direction, the first contact section 2276b touches the first contact surface 2284a of the first stop 2284. At this point, the rotation of the first position adjustment section 2276 can be limited by the first stop 2284, whereas the first gear 2274 can continue to rotate. Thus, only the first gear 2274 can rotate relative to the stationary first rotor 2276a, and when the rotation of the first gear 2274 is stopped at a position where the first contact section 2276b meets the first point P1, the position correction to the reference position can be completed.

[0252] With reference to Fig. 45. The position correction to the reference position can be carried out by rotating the first gear 2274 in one direction (e.g., clockwise). Alternatively, the position correction to the reference position can also be carried out by rotating the first gear 2274 in the opposite direction (e.g., counterclockwise).

[0253] Fig. 46 is a reference view that illustrates a state before the second potentiometer and a second stop of the in Fig. The drive device shown in section 41 is mounted, and Fig. 47 is a reference view illustrating a process in which the second potentiometer captures a starting position.

[0254] With reference to Fig. 46 and Fig. 47 can include the second potentiometer 2273, the second gear 2275, and a second position adjustment section 2277. The second gear 2275 can engage with the tilting worm gear 2249 and rotate when the tilting rotary unit 2230 (see Fig. 42) about the second axis of rotation RA2 with respect to the lower housing 2211 (see Fig. 41) rotates. The second position adjustment section 2277 can be mounted inside the second gear 2275. On the inner surface of the second gear 2275, a second tooth pattern 2275a of an internal gear type can be formed in an area facing the outer circumferential surface of the second position adjustment section 2277.

[0255] The second position adjustment section 2277 can be provided on the second gear 2275 coaxially with the axis of rotation of the second gear 2275, i.e., a fourth axis of rotation RA4. That is, the second position adjustment section 2277 can be arranged to be rotatable relative to the second gear 2275. The axis of rotation of the first gear 2274, i.e., the third axis of rotation RA3, and the fourth axis of rotation RA4, can be arranged orthogonally.

[0256] The second position adjustment section 2277 can include a second rotor 2277a, a second contact section 2277b, second leg sections 2277c, and second contact pieces 2277d. The structure of the second position adjustment section 2277 can be similar to that of the first position adjustment section 2276, and therefore a detailed description of it is omitted.

[0257] The motor installation unit 2280 can include a second stopper 2285. The second stopper 2285 can be provided within the third assembly section 2283 of the motor installation unit 2280 (see Fig. 35). The second stopper 2285 can include a projection element 2285a and a guide element 2285b.

[0258] The projection element 2285a can extend to the second contact section 2277b along the axial direction of the second rotor 2277a and guide the operating position of the second contact pieces 2277d. That is, the projection element 2285a can function to allow the second contact section 2277b to be smoothly inserted into the guide element 2285b. The projection element 2285a can include a tip section 2285c, a first guide section 2285d, and a second guide section 2285e.

[0259] The tip section 2285c can project convexly towards the center of rotation of the second rotor 2277a and establish an entry direction when the second rotor 2277a first contacts the projecting element 2285a. In other words, while in contact with the tip section 2285c, the second rotor 2277a can be guided to rotate and move either towards the first guide section 2285d or the second guide section 2285e.

[0260] The first guide section 2285d can guide the second rotor 2277a from the tip section 2285c to the guide element 2285b when the second rotor 2277a rotates in one direction about its central axis, and the second guide section 2285e can guide the second rotor 2277a from the tip section 2285c to the guide element 2285b when the second rotor 2277a rotates in the opposite direction. The first and second guide sections 2285d and 2285e can be configured such that their area or width increases from the tip of the tip section 2285c along the X and Z axes, and can be formed as inclined or curved surfaces.

[0261] The guide element 2285b can define a second reference area corresponding to the radius of rotation of the second contact section 2277b when the second contact section 2277b is assembled by the projection element 2285a. The guide element 2285b can extend downwards on both sides in a “∧” shape by an amount corresponding to the radius of rotation of the second contact section 2277b about the axis of rotation of the second gear 2275, i.e., the fourth axis of rotation RA4.

[0262] Accordingly, when the second contact section 2277b is assembled with the second stop 2285, no separate position adjustment is required, and the second contact section 2277b can rotate into any starting position and be assembled with the guide element 2285b.

[0263] Fig. 48 reference views are shown, which are in Fig. 1. Illustrate the side mirror arrangement. Table (a) of Fig. 48 shows adjustment values ​​for a side mirror arrangement of a vehicle with the steering wheel on the left (e.g. the United States and Korea), and Table (b) of Fig. Figure 48 shows adjustment values ​​for a side mirror arrangement of a vehicle with the steering wheel on the right-hand side (e.g. Japan and the United Kingdom).

[0264] Referring to Table (a) of Fig. 48 Since the driver sits on the left side with respect to the direction of travel of the vehicle, the angle of a right-hand side mirror assembly 100R can be adjusted so that it is turned towards the driver. With reference to Table (b) of Fig. 48 Since the driver is seated on the right side in relation to the direction of travel of the vehicle, the angle of a left side mirror arrangement 100L can be adjusted to increase it towards the driver.

[0265] Such settings for the side mirror arrangement of Fig. 1 can be applied automatically depending on the on / off power or the driving mode of the vehicle (P, R, N or D) and can also be automatically set to a memory value configured by each driver.

[0266] Accordingly, in the drive device according to this embodiment, the base position of the first potentiometer and / or the second potentiometer can be corrected during the assembly of the control module, the mountability of the control module can be improved and the application to stop structures of various shapes and rotation ranges can be facilitated.

[0267] Fig. 49 is an expanded perspective view illustrating a drive device for a side mirror arrangement for a vehicle according to a fourth embodiment of the present disclosure in a disassembled state, Fig. 50 is a longitudinal cross-sectional view, which shows the in Fig. 49 illustrated drive device illustrated, Fig. 51 is a reference view showing a coupled state between a lower housing and a tilt-rotation unit on a second bracket of the in Fig. 49 illustrated drive device illustrated, Fig. Figure 52 is a reference view illustrating a state in which an upper housing of the in Fig. The drive device shown in section 49 has been removed for illustrative purposes. Fig. 53 is an expanded perspective view showing a first drive unit and a second drive unit of the in Fig. 52 illustrated drive device illustrated, and Fig. 54 and Fig. 55 separated perspective views are what a coupling unit of the in Fig. Figure 53 illustrates the drive device. In the following description, identical reference symbols denote identical elements, and thus repeated descriptions are omitted.

[0268] With reference to Fig. 49, Fig. 50, Fig. 51, Fig. 52, Fig. 53, Fig. 54, Fig. 55 to Fig. 56 a lower housing 2211 can be formed with a fourth installation section 2218e in which a coupling unit 2290 to be described below is accommodated, and a second opening 2218f through which a tilting worm gear 2249', provided on a tilting rotary unit 2230, extends into the interior of the lower housing 2211.

[0269] A second potentiometer 2273 can be provided with a second gear 2275, which is arranged to be rotatable on a circuit board 2271, and the second gear 2275 can engage with a fifth gear section 2249a formed on the tilting worm gear 2249'. Accordingly, the tilting rotation angle of the tilting rotary unit 2230 can be detected based on the rotation angle of the second gear 2275 relative to a rotation of the tilting worm gear 2249' about a shaft 2243.

[0270] The tilting rotary unit 2230 can be formed with a mounting groove 2236 on a base surface 2231 according to the fourth installation section 2218e. A mounting hole 2236a, into which the tilting worm gear 2249' is coupled, can be formed near the mounting groove 2236.

[0271] The coupling unit 2290 can comprise a third worm gear 2291, a coupling gear 2292, a coupling spring 2293, and a second support piece 2294. The coupling unit 2290 can transmit the rotational force of a second drive unit 2240 about a second axis of rotation RA2 within the lower housing 2211 to the tilting rotary unit 2230, while preventing the reverse transmission of the rotational force from the tilting rotary unit 2230 to the second drive unit 2240. This can prevent damage to at least one power transmission component provided between the second drive unit 2240 and the tilting rotary unit 2230 when an external force is applied.

[0272] The third worm gear 2291 can include a rotating body 2291a and a third gear section 2291b. The rotating body 2291a can be arranged to surround the shaft 2243 and to allow the shaft 2243 to rotate. The rotating body 2291a can be designed as an essentially hollow cylinder, and the third gear section 2291b can be provided at one end of it.

[0273] The third gear section 2291b can project outwards from one end of the rotating body 2291a to engage with a third reduction gear 2247 of the second drive unit 2240. Accordingly, a rotational force for tilting, which is transmitted to the third reduction gear 2247, can be transmitted via the third worm gear 2291 to a clutch gear 2292.

[0274] An insertion groove 2291c can be formed at one end of the third worm gear 2291 adjacent to the rotating body 2291a and the third gear section 2291b. The insertion groove 2291c can be an annular groove formed along the outer circumferential surface of the rotating body 2291a within the third gear section 2291b. A section of the coupling gear 2292 can be inserted into the insertion groove 2291c.

[0275] The coupling gear 2292 can comprise a fourth gear section 2292a, an insertion body 2292b, and a projection 2292c. The fourth gear section 2292a can be coupled to surround the rotating body 2291a. The second gear 2275 can engage with the tilting worm gear 2249'. Accordingly, the rotational force for tilting, which is transmitted to the third worm gear 2291, can be transmitted via the coupling gear 2292 to the tilting worm gear 2249'. The tilting worm gear 2249' can be coupled to the tilting rotary unit 2230, so that the rotational force transmitted to the tilting worm gear 2249' can be supplied as the tilting rotational force of the tilting rotary unit 2230.

[0276] The insertion body 2292b can project integrally from one side of the fourth gear section 2292a and can be inserted, at least partially, into the insertion groove 2291c together with the projection piece 2292c.

[0277] The projection 2292c can extend along the direction of the second axis of rotation RA2 within the fourth gear section 2292a and the insertion body 2292b. For example, the projection 2292c can function as a wedge that secures a pulley to a shaft. The projection 2292c can be arranged to contact or engage with the clutch spring 2293.

[0278] The clutch spring 2293 can be designed as a hollow cylindrical spring having an opening 2293a such that one side is open along the direction of the second axis of rotation RA2. Thus, the cross-section of the clutch spring 2293 can generally be C-shaped. The clutch spring 2293 can be fitted around the outer circumferential surface of the rotating body 2291a and pressed against it. In this case, the clutch spring 2293 can be in close contact with the rotating body 2291a due to its elastic restoring force. If a rotational force greater than the elastic restoring force occurs while the clutch spring 2293 is in close contact with the rotating body 2291a, slippage can occur on the rotating body 2291a, allowing relative rotation.

[0279] While coupled to the rotating body 2291a, the clutch spring 2293 can be inserted into the clutch wheel 2292, and the opening 2293a can be coupled to correspond to the protruding piece 2292c.

[0280] The coupling unit 2290 can be arranged to be rotatable around the shaft 2243 along the second axis of rotation RA2 (also: tilting axis of rotation).

[0281] The second support piece 2294 can support the other end of the rotating body 2291a to prevent eccentricity, so that the inner circumferential surface of the fourth gear section 2292a is concentric with the shaft 2243. Since the projection piece 2292c is provided within the fourth gear section 2292a, the second support piece 2294 can be designed with a second opening 2294a corresponding to the projection piece 2292c and can be coupled to the clutch spring 2293 to support the rotating body 2291a and prevent eccentricity within the clutch gear 2292. Alternatively, the second support piece 2294 can be formed integrally with the other end of the clutch spring 2293.The shaft 2243 can be inserted into the other end of the fourth gear section 2292a of the clutch wheel 2292 to pass through it, and the other end of the fourth gear section 2292a can be partially closed so that the second support piece 2294 cannot pass through it.

[0282] The inclined worm gear 2249' can include a fifth gear section 2249a, provided on the outer top surface of the inclined worm gear 2249', and a sixth gear section 2249b, provided on the inner bottom surface of the inclined worm gear 2249'. The inclined worm gear 2249' can be detachably coupled to the inclined rotary unit 2230. The inclined worm gear 2249' can be arranged to pass through the bottom surface of the lower housing 2211, so that it is exposed within the lower housing 2211.

[0283] The fifth gear section 2249a can be arranged to mesh with the second gear 2275, which is connected to a second potentiometer 2273 to provide tilt rotation information to the second potentiometer 2273.

[0284] The sixth gear section 2249b can be arranged such that it engages with the fourth gear section 2292a of the coupling gear 2292. The inclined worm gear 2249' with a shaft hole 2249c through which the shaft 2243 passes can be formed below the sixth gear section 2249b.

[0285] The tilting worm gear 2249' can be detachably coupled to the tilting rotary unit 2230. In this case, fastening hooks 249d can be provided at both ends for insertion into the tilting rotary unit 2230.

[0286] Accordingly, when a rotational force is generated in the third worm gear 2291, the clutch spring 2293 rotates, and the clutch gear 2292 also rotates, as it is locked to the clutch spring 2293 by the projection 2292c. When the clutch gear 2292 rotates, the tilting worm gear 2249' rotates, and as a result, the tilting rotary unit 2230 can perform a tilting rotation. Conversely, when an external force acts on the tilting rotary unit 2230, the tilting worm gear 2249' rotates and drives the clutch gear 2292. Since the third worm gear 2291 engages with the second drive unit 2240 and cannot rotate, slippage can occur between the clutch gear 2292 and the rotating body 2291a.This means that although the clutch spring 2293 rotates together with the clutch wheel 2292 due to interference with the projection 2292c, slippage is allowed between the clutch wheel 2292 and the rotating body 2291a, enabling them to rotate relative to each other. Thus, the clutch unit 2290 can prevent damage between the second drive unit 2240 and the tilting rotary unit 2230 caused by an external force.

[0287] Fig. 57 and Fig. 58 reference views are shown, which depict the coupling unit of Fig. 54 illustrate in an operating state.

[0288] With reference to Fig. 57 and Fig. 58 The shaft hole 2249c of the inclined worm gear 2249' can be designed as an elongated slot. When the fourth and sixth gear sections 2292a and 2249b engage and rotate relative to each other, the inclined worm gear 2249' can move while rotating along the slot direction of the shaft hole 2249c.

[0289] As in Fig. As illustrated in Figure 57, when the coupling unit 2290 rotates, the fourth gear section 2292a can engage with the sixth gear section 2249b, causing the inclined worm gear 2249' to rotate. In this case, although the shaft 2243 passes through the shaft hole 2249c and is fixed in position on the lower housing 2211, the inclined worm gear 2249' can undergo a predetermined horizontal movement.

[0290] As in Fig. Figure 58 illustrates how the clutch unit 2290 moves when it is in Fig. In the illustrated state 57, the inclined worm gear 2249' continues to rotate further to the right around the shaft 2243. At this point, the coupling unit 2290 can only complete one rotation around the shaft 2243.

[0291] The center of rotation of the inclined worm gear 2249' can be located above or below the shaft 2243 instead of on the shaft 2243. Therefore, when the coupling gear 2292 rotates, the inclined worm gear 2249' can undergo a horizontal movement along with a rotation.

[0292] Accordingly, in the drive device of this embodiment, by providing a coupling unit on the path along which the tilting torque is transmitted from the second drive unit, damage to the second drive unit caused by an external force can be prevented, and if an external force is applied that is greater than a predetermined threshold, manual rotation is enabled while the second drive unit is at rest.

[0293] Fig. 59 is a perspective view illustrating a drive device for a frameless mirror arrangement for a vehicle according to a fifth embodiment of the present disclosure, and Fig. 60 is an expanded perspective view, which is in Fig. 59 illustrated drive device in a disassembled state.

[0294] With reference to Fig. 59 and Fig. 60 can comprise a frameless mirror assembly 100 for a vehicle and a drive unit 3200 for a vehicle side mirror. The drive unit 3200 can include: a motor housing 3210 located within a mirror housing 110 (see Fig. 6) is provided; a first drive unit 3220, which is involved in a folding rotation of the mirror housing 110; a tilting rotation unit 3230; a second drive unit 3240, which is involved in a tilting rotation of the tilting rotation unit 3230; and a mounting module 3250 and a control module 700 (see Fig. 62), which are provided on a fastening part 17.

[0295] The motor housing 3210 can include a lower housing 3211 and an upper housing 3212. A support guide 3219 can be included as in the aforementioned embodiments. The lower housing 3211 can be arranged within a lower housing 111, and the upper housing 3212 can be coupled to the upper side of the lower housing 3211 to form the motor housing 3210. In this case, although the motor housing 3210 is arranged within the mirror housing 110, it may not be coupled to the mirror housing 110, but only to the mounting part 17.For example, the first drive unit 3220 can drive a folding rotation of the mirror housing 110 to provide a relative rotation of the motor housing 3210 with respect to the mounting module 3250 about a first axis of rotation RA1 formed on the mounting part 17, and the second drive unit 3240 can provide a relative rotation to the tilting rotation unit 3230 about a second axis of rotation RA2 formed between the motor housing 3210 and the tilting rotation unit 3230, thereby providing a tilting drive of the mirror housing 110.

[0296] The lower housing 3211 can include a cylindrical section 3213 and a tilt shaft mounting section 3214. The cylindrical section 3213 can project downwards from one side of the lower housing 3211 and can be formed in a cylindrical shape to surround the mounting part 17 when the mounting part 17 is inserted in its center.

[0297] A support element 3215 can additionally be attached around the cylindrical section 3213. Since the support element 3215 is attached around the cylindrical section 3213, with a section of the tilting rotary unit 3230 arranged between the lower housing 3211 and the support element 3215, the support element 3215 can support one side of the tilting rotary unit 3230.

[0298] The support element 3215 can include guide elements 3216 that ensure correct alignment for coupling with the lower housing 3211. The guide elements 3216 can be configured as one or more projections and grooves facing the lower side of the lower housing 3211. In this embodiment, for example, one or more groove-like guide elements 3216 arranged along a straight line can be provided on the upper surface of the support element 3215. One or more projections 3213a with a shape corresponding to the guide elements 3216 can be formed on the outer circumferential surface of the cylindrical section 3213 of the lower housing 3211. Accordingly, the coupling direction of the support element 3215 with the lower housing 3211 can be adjusted by the guide elements 3216.Additionally, the guide elements 3216 and the projections 3213a can engage with each other along the folding direction of rotation, so that the support element 3215 and the cylindrical section 3213 can rotate together when the motor housing 3210 folds.

[0299] The support element 3215 can further include a pair of support ends 3217 projecting towards the bottom surface of the lower housing 3211. The support ends 3217 can be spaced apart from each other along the axial direction of the second axis of rotation RA2 around the cylindrical section 3213 and can rotatably support one side of the tilting rotary unit 3230, which will be described later.

[0300] The support element 3215 can be arranged to be rotatable on the mounting part 17 by means of a folding rotation. In this case, a bushing 3218 can additionally be provided in an area where the support element 3215 and the mounting part 17 contact each other.

[0301] The tilt shaft mounting section 3214 can support the other side of the tilt rotation unit 3230 on the other side of the lower housing 3211. A shaft 3243, arranged on the second axis of rotation RA2 of the lower housing 3211, can be attached to the tilt shaft mounting section 3214, and the tilt rotation unit 3230 can be coupled to the shaft 3243 to be rotatable about the second axis of rotation RA2.

[0302] The tilting rotary unit 3230 can be arranged to rotate relative to the motor housing 3210 about the second axis of rotation RA2 (i.e., the tilting axis of rotation), which is formed at a lower center of the motor housing 3210. The tilting rotary unit 3230 can rotate in a tilting direction by being driven by the second drive unit 3240. In this case, the tilting rotary unit 3230 can perform a tilting rotation about the second axis of rotation RA2 together with the mirror housing 110 and a reflector 120.

[0303] The tilting and rotating unit 3230 can include a base surface 3231, a first support 3232, a second support 3233, and a side wall 3234. The base surface 3231 can be arranged to face the base surface of the lower housing 3211 with a gap between them. The base surface 3231 and the lower housing 3211 can be spaced apart from each other to allow relative rotation in conjunction with tilting.

[0304] A first support 3232 and a second support 3233 can be arranged on the base surface 3231, spaced apart from each other. The first support 3232 can support one side of the base surface with respect to the second axis of rotation RA2, and the second support 3233 can support the other side of the base surface 3231 with respect to the second axis of rotation RA2.

[0305] The first support 3232 can include a pair of support pieces 3235 spaced apart from each other along the second axis of rotation RA2 with respect to the cylindrical section 3213. The support pieces 3235 can be arranged on the respective support ends 3217 of the support element 3215 to be in surface contact.

[0306] The side wall 3234 can be arranged to face both side surfaces of the lower housing 3211 and to surround the lower housing 3211. Accordingly, the tilting and rotating unit 3230 can be arranged to be tiltable about the second axis of rotation RA2 on the lower housing 3211.

[0307] The tilt-rotation unit 3230 can also be arranged within the mirror housing 110 together with a mounting frame 3260. Although the tilt-rotation unit 3230 is only attached to the lower housing 3211, with the mounting frame 3260 also being provided, the tilt-rotation unit 3230 can be rigidly attached to the upper housing 112 and the backplate 130 via the mounting frame 3260. The mounting frame 3260 can perform a tilt rotation about the second axis of rotation RA2 together with the mirror housing 110 and can more firmly support the structure in which the tilt-rotation unit 3230 rotates within the mirror housing 110.

[0308] A detailed description of the mounting module 3250 and the control module 700 will now be given.

[0309] Fig. 61 is a reference view illustrating a state in which the upper casing of the in Fig. The drive device shown in section 59 has been removed for illustrative purposes, and Fig. 62 is an expanded perspective view showing the first and second drive units of the in Fig. 61 illustrated drive device illustrated.

[0310] With reference to Fig. 61 and Fig. 62 The first drive unit 3220 can include a first motor 3221 and a first gear module 3222. Accordingly, the first drive unit 3220 can enable a folding rotation via the end output of the first gear module 3222 in response to the rotation of the first motor 3221.

[0311] The first gear module 3222 can include a first worm gear 3223 and a first reduction gear 3224. The first worm gear 3223 can be coupled to the drive shaft of the first motor 3221. The first worm gear 3223 can transmit a torque to the first reduction gear 3224.

[0312] The first reduction gear 3224 can mesh with the first worm gear 3223, and the rotating shaft of the first reduction gear 3224 can be oriented in a direction different from that of the rotating shaft of the first worm gear 3223. The first reduction gear 3224 can include a plurality of first gears 3224a and a second gear 3224b, which provide a predetermined gear ratio and rotate together.

[0313] Accordingly, the final output of the first gear module 3222 can be supplied to the first reduction gear 3224. A driven gear 3251 of the mounting module 3250 can mesh with the second gear 3224b of the first reduction gear 3224, and the motor housing 3210 can rotate relative to the driven gear 3251, so that a folding rotation can occur.

[0314] The second drive unit 3240 can include a second motor 3241, a second gear module 3242, and a shaft 3243. The second gear module 3242 can include a second worm gear 3245 and a second reduction gear 3246. The second worm gear 3245 can be coupled to the drive shaft of the second motor 3241. The second worm gear 3245 can transmit a torque to the second reduction gear 3246.

[0315] The second reduction gear 3246 can mesh with the second worm gear 3245, and the drive shaft of the second reduction gear 3246 can be oriented in a direction different from that of the drive shaft of the second worm gear 3245. The second reduction gear 3246 can include a plurality of gears that provide a predetermined gear ratio and rotate together.

[0316] The second drive unit 3240 can further include a third reduction gear 3247, which meshes with the second reduction gear 3246. In this case, the second and third reduction gears 3246 and 3247 can provide different gear ratios. The third reduction gear 3247 can transmit the final output to the shaft 3243, which is connected to a third worm gear 3248.

[0317] The mounting module 3250 can elastically support the motor housing 3210 on the mounting part 17. The mounting module 3250 can include the driven gear 3251, a clamping plate 3252, a clamp 3253, an elastic element 3254, and an auxiliary gear 3255.

[0318] The driven gear 3251 can be arranged within the motor housing 3210, such that the mounting part 17 extends into the interior of the motor housing 3210. Although the driven gear 3251 is coupled and fixed to the mounting part 17 and therefore does not rotate with respect to the mounting part 17, the rotational force transmitted from the first reduction gear 3224 to the driven gear 3251 can cause the motor housing 3210 to rotate relative to the driven gear 3251, thus producing a hinge rotation. That is, the driven gear 3251 can be fixed to the mounting part 17, and the first reduction gear 3224 can rotate while remaining engaged with the driven gear 3251.

[0319] The clamping plate 3252 can be attached to a distal end of the mounting part 17 by the clamp 3253. The elastic element 3254 can provide an elastic support between the driven gear 3251 and the clamping plate 3252.

[0320] The secondary gear 3255 can be arranged to surround the outside of the elastic element 3254 and can be arranged on the driven gear 3251. Gear teeth can be formed on the outer circumferential surface of the secondary gear 3255 to engage with a section of the control module 700, which will be described later, and the state of the folding rotation of the motor housing 3210 with respect to the secondary gear 3255 can be transmitted to the control module 700.

[0321] The control module 700 can include a first potentiometer 710, which detects a rotation of the first drive unit 3220, a second potentiometer 720, which detects a rotation of the second drive unit 3240, and a circuit board 730.

[0322] The first and second potentiometers 710 and 720 can each be mounted on the circuit board 730. Each of the first and second potentiometers 710 and 720 can be implemented by a variable resistor that converts a linear displacement or a rotational displacement into a change in electrical resistance. The first and second potentiometers 710 and 720 can be of a contact or non-contact type. In this embodiment, the first and second potentiometers 710 and 720 are described, for example, as contact types. In a contact-type potentiometer, a brush moves on a resistive element so that a displacement can be measured according to a rotation angle or a number of rotations.

[0323] The first potentiometer 710 can be provided with a first gear 3274, which is arranged so that it is rotatable on the circuit board 730, and the first gear 3274 can mesh with gear teeth 3256 of the secondary gear 3255. Accordingly, the tilting rotation angle of the motor housing 3210 can be detected based on the rotation angle of the first gear 3274 relative to the gear teeth 3256 of the secondary gear 3255.

[0324] The second potentiometer 720 can be provided with a second gear 3275, which is arranged to be rotatable on the circuit board 730, and the second gear 3275 can engage with gear teeth formed on a tilting worm gear 3249. Accordingly, the tilting rotation angle of the tilting rotary unit 3230 can be detected based on the rotation angle of the second gear 3275 relative to a rotation of the tilting worm gear 3249 about the shaft 3243.

[0325] The shaft 3243 can be coupled to both the third worm gear 3248 and the inclined worm gear 3249 so that they can rotate together. The third worm gear 3248 can mesh with the third reduction gear 3247 and thereby transmit an output to the shaft 3243. The third worm gear 3248 and the inclined worm gear 3249 can be formed integrally. The inclined worm gear 3249 can be arranged to rotate in a limited manner within a predetermined angular range according to the rotation of the shaft 3243.

[0326] A description of a control device is now given that controls the operation of the frameless mirror arrangement according to an embodiment of the present disclosure.

[0327] Fig. Figure 63 is a block diagram illustrating a control device for a frameless mirror arrangement for a vehicle according to an embodiment of the present disclosure, Fig. 64 is a block diagram that shows the configuration of a control module of the in Fig. 63 illustrated control device illustrated, and Fig. Figure 65 is a reference view showing a first axis of rotation and a second axis of rotation of a frameless mirror. Fig. 63 illustrated.

[0328] With reference to Fig. 63, Fig. 64 to Fig. 65 can comprise a frameless mirror assembly 100 for a vehicle and a control device for a vehicle side mirror. Here, the control device can correspond to a control module 700 arranged within a mirror housing 110 and can also simply be referred to as the control module 700.

[0329] The control device can include a controller 740 and the control module 700. The controller 740 and the control module 700 can be installed together within a motor housing 3210 (see Fig. 59 and Fig. 61).

[0330] First, the 740 controller can be configured to receive power from a 701 smart junction box (SJB) installed in the vehicle. The 701 SJB can distribute power from the vehicle's battery to any required vehicle component and can transmit and receive information with the 700 control module and various sensors via Controller Area Network (CAN) communication. The 740 controller can also be configured to receive a user control signal from a 702 Door Area Unit (DAU) via CAN or Local Interconnect Network (LIN) communication.

[0331] The control module 700 can include a first potentiometer 710, a second potentiometer 720, and a circuit board 730. The functions and operation of the first and second potentiometers 710 and 720 are as described above, and detailed descriptions are omitted.

[0332] The circuit board 730 can include a sequence controller 731, a speed controller 732 and a memory 733.

[0333] The sequence controller 731 and the speed controller 732 can be implemented, for example, as control logic stored in memory 733 or as a printed circuit board (PCB) circuit. The sequence controller 731 can be configured to determine the drive sequence of a first drive unit 3220 (or a first motor 3221) and a second drive unit 3240 (or a second motor 3241) and to control the first and second drive units 3220 and 3240 to drive sequentially in the determined drive sequence.

[0334] The speed control 732 can be configured to use pulse width modulation control logic (PWM control logic) to finely adjust the rotation angle of the first drive unit 3220 about a first rotation axis RA1 or the position of the motor housing 210 (see Fig. 11) to enable.

[0335] The circuit board 730 can selectively supply power to at least one of a blindspot collision warning (BCW) unit 703, a heater 704 for a frameless mirror, a puddle light 705 and a turn signal.

[0336] The 732 speed controller can also be configured to control the voltages supplied to the first and second drive units 3220 and 3240 according to an external temperature. That is, when power is applied to the vehicle, a temperature sensor mounted outside the vehicle can detect the current ambient temperature. By comparing the detected temperature with a reference temperature, the voltage supplied to each of the first and second drive units 3220 and 3240 can be adjusted.

[0337] For example, if the reference temperature is set to 25 °C and the current ambient temperature deviates from a set range, the speed controller 732 can be configured to supply a high or low voltage depending on whether the ambient temperature is low or high. The memory 733 can store reference temperature and reference current data in a lookup table format, and the speed controller 732 can be configured to compare the reference temperature with the current temperature and, based on the result of this comparison, supply a variable voltage to each of the first and second drive units 3220 and 3240.

[0338] The following describes a sequence control and a speed control of the first and second drive units 3220 and 3240 via the control module 700.

[0339] Fig. Figure 66 is a reference view illustrating a frameless mirror switch provided on a driver's side door of a vehicle, and Fig. Figure 67 shows graphs that demonstrate a difference in rotation time according to flapping or fine tilting about the first axis of rotation using the data in Fig. 63 illustrate the control device.

[0340] Fig. 66 and Fig. Figure 67 schematically illustrates a switch 800 for controlling a frameless mirror (i.e., an exterior mirror) provided on the driver's side door of a vehicle. Referring to Fig. 66 and Fig. 67 The switch 800 can include a fine tilt switch 810, a flip switch 820 and a mirror selection switch 830.

[0341] In a frameless mirror, unlike in a conventional side mirror structure, the reflective element 120 rotates (see Fig. 3) together with the mirror housing 110 (see Fig. 3) with essentially no relative movements between the reflecting part 120 and the mirror housing 110. Therefore, the reflecting part 120 and the mirror housing 110 can simultaneously perform a folding or tilting rotation.

[0342] In this embodiment, the control can be implemented such that, compared to rotating from a first position, which corresponds to a fully extended position, to a second position, which corresponds to a fully folded position, via the actuation of the folding switch 820, the frameless mirror can be configured to rotate more slowly from the first position to a position between the first and second positions for a fine tilt (i.e., adjustment) via the actuation of the fine tilt switch 810.

[0343] Here, "fine inclination" means a rotation in the folding or unfolding direction around the first axis of rotation RA1 (see Fig. 65), but at a much lower rotational speed than when rotating to the fully folded second position or the fully extended first position. To avoid confusion between folding and fine tilting about the first axis of rotation RA1 and tilting about the second axis of rotation RA2 (see Fig. 65) To avoid, the axis of rotation, which serves as the center of rotation, is specified together below.

[0344] Preferably, the flapping and fine tilting about the first axis of rotation RA1 can be set as standard to operate separately from or sequentially after the tilting about the second axis of rotation RA2. This setting can prevent friction or operational interference that may occur when flapping and tilting operate simultaneously.

[0345] By assigning different rotational speeds for full flapping and fine tilting, as described above, the speed control 732 (see Fig. 64) enable a user (e.g. a driver) to make a finer, more stable and more sensitive adjustment of the frameless mirror during fine tilting.

[0346] In Fig. 67 shows the rotational speeds of full flapping and fine tilting as different applied voltages. Table (a) of Fig. Figure 67 shows a first graph G1 of the stress versus time during ordinary complete folding, and Table (b) of Fig. Figure 67 shows a second graph G2 of the voltage versus time for fine tilting. For comparison, the first graph G1 is shown in Table (b) of Fig. 67 reproduced.

[0347] The second graph G2 for fine tilting indicates that a relatively lower voltage is applied, and it takes more time to reach the same position (or angle) compared to the first graph G1 for full tilting. Since a single first drive unit can perform both full tilting and fine tilting about the first axis of rotation RA1 (see Fig. 65) carries out this approach insofar as it can clearly identify the difference between the rotational speeds of full flapping and fine tilting where such a difference in rotational speed is unavoidable.

[0348] Along with the speed difference between full flapping and fine tilting, additional effects can be obtained by varying the speed during the process of full flapping or full unfolding.

[0349] For example, the speed control 732 (see Fig. 64) can be configured to control the rotational speed of the folding mechanism to gradually decrease before the mirror fully folds in during a rotation from the first to the second position. Similar to a performance window that reduces its closing speed to provide a soft closing action that minimizes impact noise and vibration and delivers a premium feel, gradually slowing the rotation of the frameless mirror before it fully folds in can provide a smoother, more refined stop, thereby reducing impact noise and vibration while offering a premium operating feel. Likewise, the rotational speed control can be configured during unfolding to decrease the unfolding rotational speed before the mirror reaches the fully extended first position.

[0350] Fig. 68 reference views are shown, illustrating a state in which the frameless mirror is positioned using the control device of Fig. 63 turns into an unfolded or folded state, and Fig. 69 reference views show a stop of Fig. Figure 62 illustrates the limitation of the rotation of the frameless mirror in the folding or unfolding direction.

[0351] The tablet (a) of Fig. Figure 68 illustrates a state in which tilting about the second axis of rotation RA2 is carried out while the frameless mirror is unfolded, and plate (b) of Fig. Figure 68 illustrates a fully folded state of the frameless mirror. The sequence control 731 (see Fig. 64) can be configured to set the control sequence of the first and second drive units 3220 and 3240, and such settings can be stored in memory 733 (see Fig. 64) are stored.

[0352] For example, after the frameless mirror has been fully folded from the first position to the second position around the first axis of rotation RA1, the sequence control 731 can be configured to limit or prevent tilting rotation around the second axis of rotation RA2. In other words, when the frameless mirror is fully folded, it can preferably maintain a constant direction and angle. The angle to which the frameless mirror faces in its fully folded state can be adjusted within a set range. The first and second positions can also be adjusted individually, and once the settings are complete, the setting information can be stored in memory 733 (see Fig. 64) are stored.

[0353] Additionally, the 731 sequence controller can be configured to control the frameless mirror to return from the state in which it is tilted about the second axis of rotation RA2 before folding into the fully retracted second position. That is, the 731 sequence controller can allow tilting or fine tilting in the extended position, limit tilting or fine tilting in the retracted position, and also limit full folding in the state in which the frameless mirror is excessively tilted from the fully extended position.

[0354] Memory 733 (see Fig. 64) can store the rotation position of the frameless mirror based on information provided by the first potentiometer 710 and / or the second potentiometer 720.

[0355] For example, the support element 3215 can be arranged to be rotatable relative to the fastening part 17, and a stop provided between the underside of the support element 3215 and the fastening part 17 can limit the rotation in the folding and unfolding direction about the first axis of rotation RA1. The stop can include first stepped sections 17a formed at equal intervals on the outer circumferential surface of the fastening part 17, and second stepped sections 3215a provided on the underside of the support element 3215 to each interfere with the first stepped sections 17a during a folding or unfolding rotation.

[0356] Memory unit 733 can store scan information corresponding to the time during which the frameless mirror rotates, or the change in voltage during rotation, after the frameless mirror has rotated to its maximum position in either the folding or unfolding direction, such that the first stepped sections 17a touch the second stepped sections 3215a on one side, and then rotates to its maximum position in the opposite direction, so that the first stepped sections 17a touch the second stepped sections 3215a on the other side. Accordingly, based on the scan information, memory unit 733 can store both the first position, which is the unfolded position of the frameless mirror, and the second position, which is the position of the frameless mirror fully folded from the first position.The 733 storage unit can also store precise position information for the tilt center of the frameless mirror at the first position, as well as information about user-customized individual tilt angles at the first position.

[0357] Fig. 70 is a block diagram illustrating a control device for a side mirror arrangement for a vehicle according to another embodiment of the present disclosure.

[0358] With reference to Fig. According to another embodiment of the present disclosure, the control device 70 can include a controller 740' and a control module 700'. The controller 740' can be installed on a vehicle outside of a frameless mirror, so that power and control signals can be provided by the vehicle.

[0359] The control module 700' can include a first potentiometer 710, a second potentiometer 720, and a circuit board 730. The first and second potentiometers 710 and 720 can provide measured voltages to the controller 740', which is installed in the vehicle.

[0360] In this case, the circuit board 730 can be controlled by a control signal provided by the control unit 740' or by another control device (e.g. an electronic control unit (ECU)) of the vehicle and can be used as a dummy board.

[0361] According to the aforementioned embodiments of the present disclosure, optimized functions can be provided for the frameless mirror, the number of actuators can be reduced by enabling simultaneous folding and tilting of the mirror housing and the frameless mirror, the folding rotation and tilting rotation can be performed independently while controlling the rotational speeds for the folding rotation and fine tilting, and a consistent folded appearance can be maintained while enabling adjustment for the folding and tilting.

Various modifications may be made without deviating from the scope of this disclosure. Accordingly, such modifications should also be considered to fall within the scope of this disclosure, as defined by the claims set forth below. QUOTES INCLUDED IN THE DESCRIPTION
