Description

Technical Field

[0001] This invention relates to a rearview mirror assembly for vehicles, and more specifically, to a rearview mirror assembly for vehicles with improved folding and tilting structures. Background Technology

[0002] Typically, vehicles are equipped with an interior rearview mirror to allow the driver to see what's behind the vehicle, and exterior rearview mirrors on both sides to allow the driver to see what's behind and to the sides. Drivers can use the visibility provided by the interior and exterior rearview mirrors to judge surrounding vehicles and pedestrians, and to perform maneuvers such as reversing, overtaking, and changing lanes.

[0003] Recently, in order to reduce air resistance while driving and lower the possibility of damage from external impacts, camera mirrors, which include cameras, are being used to replace exterior rearview mirrors. Since the image of the vehicle's surroundings obtained by the camera mirror is displayed on a display device equipped inside the vehicle, the driver can easily grasp the situation around the vehicle.

[0004] Additionally, when driving, the exterior rearview mirrors or camera mirrors are deployed to allow the driver to be aware of the vehicle's surroundings. However, when parking or passing through narrow spaces, the exterior rearview mirrors or camera mirrors need to be folded towards the side of the vehicle to prevent damage or to ensure sufficient space around the vehicle. In such cases, the driver can use an actuator or manually rotate the exterior rearview mirrors or camera mirrors.

[0027] Furthermore, the present invention provides a rearview mirror assembly for a vehicle, comprising: a base, one side connected to a vehicle and the other side having a fixing portion to form a folding rotation axis at the center of the fixing portion; a motor housing, including a lower housing and an upper housing covering the upper part of the lower housing, which rotates relative to each other about the fixing portion fixed to the vehicle; a tilting rotation portion housed inside the motor housing, which rotates relative to each other about the tilting rotation axis formed in the lower part of the motor housing; a second drive portion, which drives a second motor to tilt and rotate the tilting rotation portion relative to the motor housing; a clutch portion, which transmits the rotational force of the second drive portion to the tilting rotation portion about the tilting rotation axis and prevents the rotational force from being transmitted from the tilting rotation portion to the second drive portion; a mirror housing, including an upper housing, a lower housing coupled to the upper housing, and a reflective portion sandwiched between the upper housing and the lower housing, and housing the motor housing inside therein; and a fixing frame, which is fastened to the mirror housing and the tilting rotation portion, wherein the mirror housing equipped with the reflective portion, the tilting rotation portion, and the fixing frame rotate simultaneously in a tilting direction or a folding direction.

[0028] The clutch unit may include: a third worm gear arranged to mesh with the second drive unit around a shaft configured along the inclined rotation axis; a clutch gear arranged parallel to the third worm gear on the shaft; and a clutch spring sandwiched between the third worm gear and the clutch gear and selectively transmitting rotational force.

[0029] The third worm gear may include: a rotating body arranged to surround the shaft; and a third gear portion protruding outward from one end of the rotating body and having its outer peripheral surface meshing with the second drive portion, wherein an insertion groove for one side of the clutch gear to be inserted may be formed on the inner side of the third gear portion adjacent to the rotating body.

[0030] The clutch gear may include: a fourth gear portion formed on the outer peripheral surface; an insertion body protruding from one side of the fourth gear portion and inserted into the insertion groove; and a protruding piece protruding from the inner side of the fourth gear portion and the insertion body along the tilting rotation axis direction.

[0033] The clutch spring may have an opening that is open on one side along the direction of the inclined rotation axis and be tightly engaged in a manner that surrounds the rotating body, so that the opening can be engaged inside the clutch gear in such a manner that it corresponds to the protruding plate.

[0034] The rotational force of the second drive unit can be transmitted to the tilting worm gear in sequence through the third worm gear, the clutch spring, and the clutch gear. When the tilting rotating part generates an external force, the rotational force can be transmitted to the tilting worm gear, the clutch gear, and the clutch spring in sequence, and sliding may occur between the clutch spring and the rotating body.

[0035] The tilting rotating part may include: a tilting worm gear that transmits the rotation amount of the tilting rotating part to the second potentiometer; and a gear mounting part that is provided with a third worm gear so that the tilting rotating part tilts and rotates by the rotational force of the second driving part, wherein the third worm gear may include: a gear tooth profile that is formed to correspond to the rotation radius of the tilting rotating part and is exposed inside the lower housing; and a main body that is arranged at least on the outer contour of the gear tooth profile and is pressurized and fixed to the tilting rotating part by the lower housing.

[0036] The lower housing may have an exposure hole that exposes the third worm gear attached to the tilting rotating part to the interior of the lower housing.

[0038] Inside the motor housing, a recess may be formed on one side of the driven gear that is fastened to the fixed part and the secondary gear that is in close contact with and rotates simultaneously with the driven gear or is spaced apart from the driven gear and rotates relative to the driven gear, and a protrusion corresponding to the recess may be provided on the other side. The driven gear may be arranged to be able to rotate relative to the secondary gear when an external force is applied between the driven gear and the secondary gear.

[0039] The lower housing may include one or more stops protruding toward the driven gear on the inner bottom surface. The driven gear may have a stop groove for the stop to be inserted. The lower housing can be electrically folded and rotated within the angle range in which the stop and the stop groove interfere. When an external force is applied, the driven gear and the secondary gear can be separated to rotate relative to each other while the folding and rotation can be manually achieved.

[0040] The lower housing may include: a cylindrical portion that protrudes from a lower side in a manner that surrounds the periphery of the fixing portion; and a support guide disposed on a lower surface of one side of the lower housing around the periphery of the cylindrical portion and formed as a second curved surface that protrudes upward.

[0042] The vehicle rearview mirror assembly may further include: a support member, fastened to the periphery of the cylindrical portion by the fixing portion, and equipped with a support end protruding in a manner that contacts the lower surface of the first support piece, wherein the first support piece and the contact end may be formed as first curved surfaces with support surfaces facing each other.

[0043] The vehicle rearview mirror assembly may further include: a motor mounting section, wherein a first drive section that drives a first motor to fold and rotate the motor housing relative to a fixed section is mounted on one side of the motor mounting section, and a second drive section that drives a second drive section to tilt and rotate the tilting rotation section relative to the motor housing is mounted on the other side of the motor mounting section, thereby simultaneously mounting the first drive section and the second drive section inside the motor housing.

[0044] Other specific details are provided in the detailed description and accompanying drawings.

[0045] The vehicle rearview mirror assembly according to an embodiment of the present invention has the following effects.

[0046] First, because the mirror and its housing together achieve rotation based on folding or tilting, the frame line of the mirror's outline can be minimized.

[0047] Secondly, costs can be reduced by simplifying the structure of the first drive unit that folds the mirror housing and the second drive unit that tilts the mirror housing.

[0048] Third, by optimizing the components of the drive module, we can ensure the freedom to improve the mirror design.

[0049] The effects of this invention are not limited to those mentioned above, and those skilled in the art will clearly understand other effects not mentioned through the description in the claims. Attached Figure Description

[0135] Reference Figure 4 The mirror housing 110 can be folded or unfolded relative to the base 11.

[0136] "Mirror casing 110 is folded" means that... Figure 4As shown in (a), the outer front end of the mirror housing 110 or the reflector 120 is rotated based on the first rotation axis RA1 while approaching the body 12 or door 13 of the vehicle 10. For example, if the mirror housing 110 is folded, the overall width of the vehicle 10 is reduced, thus ensuring lateral space for the vehicle when it is parked or when the vehicle 10 is passing through narrow roads.

[0137] Furthermore, "the mirror casing 110 is unfolded" indicates that... Figure 4 As shown in (b), the outer front end of the mirror housing 110 or the reflector 120 is rotated away from the body 12 or door 13 of the vehicle 10 while the mirror housing 110 is unfolded. That is, normally, when the vehicle 10 is being driven, the mirror housing 110 is unfolded, thus providing the driver with a reflected view of the side and rear of the vehicle 10.

[0138] Furthermore, the base cover 14 may include a first cover 14a disposed on the upper part and a second cover 14b joined to the opposite side of the first cover 14a with the base 11 as the center. The first cover 14a and the second cover 14b may be joined together to surround the base 11.

[0139] At this time, a lamp portion 16, formed within a defined range and selectively illuminated, can be disposed in the area facing the first cover 14a and the second cover 14b. This lamp portion 16 can be positioned in front of or to the side of the base cover 14. For example, the lamp portion 16 can provide a side repeater function. Although not shown in the figures, a lamp portion 16 can also be disposed behind the base cover 14, and can be mounted on the lower housing 111 (see reference 14b). Figure 6 ) or upper outer shell 112 (refer to Figure 6 It can also be installed in the joint area between the lower housing 111 and the upper housing 112. Furthermore, a camera (not shown) for photographing the surroundings of the vehicle can also be installed on the base cover 14. For example, if the base cover 14 is equipped with a camera (not shown), the camera can be installed on the lower part of the second cover 14b.

[0140] Figure 5 It is shown Figure 3 The image shows a three-dimensional view of a vehicle's rearview mirror assembly tilted.

[0141] Reference Figure 5 The mirror housing 110 can be tilted relative to the base 11 within a set angle range.

[0142] "Mirror housing 110 is tilted" means that mirror housing 110 is tilted based on the second rotation axis RA2 in the horizontal direction. Figure 5While rotating from state (a) to state (b), the vertical field of vision angle is adjusted. For example, tilting rotation can tilt the mirror housing 110 upward or downward to easily ensure the side and rear view according to the driver's eye height, or it can automatically or selectively tilt downward to easily identify the parking lines on the bottom of the parking lot during parking.

[0143] Figure 6 and Figure 7 It is to separate and show Figure 3 The image shown is an exploded perspective view of a vehicle rearview mirror assembly. Figure 8 It is shown Figure 3 The diagram shows a cross-sectional view of the internal structure of a vehicle rearview mirror assembly.

[0144] Reference Figures 6 to 8 According to an embodiment of the present invention, a vehicle rearview mirror assembly may include a mirror housing 110, a reflector 120, a back plate 130, a frame 140, and a drive device 200.

[0145] The base 11 can be formed of metal, and a fixing part 17 is provided on the other side of the base 11 to attach to the vehicle rearview mirror assembly 100. The fixing part 17 can be fastened by a three-point bolt connection at the other end of the base 11, or it can be formed integrally with the base 11.

[0146] A fixing module 250, to which the drive device 200 is attached, can be integrated into the fixing part 17 (see reference). Figure 10 Furthermore, the mirror housing 110, which is connected to the fixing module 250, can rotate based on the first rotation axis RA1 formed at the center of the fixing part 17.

[0147] The mirror housing 110 may include a lower housing 111 and an upper housing 112.

[0148] The lower outer casing 111 can be arranged to rotate relative to the fixing part 17 fixed to the other end of the base 11. An insertion part 14c can be provided in one of the first cover 14a of the base cover 14 and the lower outer casing 111, and a connecting part 113 can be provided in the other. A through hole 113a can be formed in the center of the connecting part 113 to allow the fixing part 17 to be inserted.

[0149] The insertion part 14c can be integrally formed with the first cover 14a. Of course, the insertion part 14c can also be separately constructed in a manner that allows it to be detached from or attached to the first cover 14a and assembled in a combined structure.

[0150] Although the example shown is of the first cover 14a and the second cover 14b arranged vertically relative to each other, it is also possible to illustrate this. Figure 6The reference lines are arranged in a front-back direction (or a left-right direction) and assembled together. Thus, when the first cover 14a and the second cover 14b are arranged in a front-back direction, half of the shape of the insertion part 14c can be respectively configured on the first cover 14a and the second cover 14b to form an insertion part 14c during assembly, or a complete insertion part 14c can be configured as either one side of the first cover 14a and the second cover 14b.

[0151] The connecting portion 113 formed on the lower outer shell 111 can be formed protruding toward the insertion portion 14c formed on the first cover 14a.

[0152] The insertion portion 14c formed at the front end of the first cover 14a can be configured to allow at least a portion of the connecting portion 113 formed on the lower housing 111 to be inserted. The insertion portion 14c and the connecting portion 113 can be arranged to face each other, and at least the outer peripheral surface of the connecting portion 113 can be formed with a first curved surface corresponding to the folding or tilting radius of the mirror housing 110.

[0153] A first sealing member 150 may be additionally arranged between the insertion part 14c and the connecting part 113.

[0154] The first sealing member 150 can be arranged to surround the inner circumferential surface of the insertion portion 14c, and can provide a sealing function between the insertion portion 14c and the connecting portion 113. The first sealing member 150 can be attached to the inside of the insertion portion 14c from the lower part of the first cover 14a toward the fixing portion 17.

[0155] The first sealing component 150 may include a first component 151 and a second component 152.

[0156] The first component 151 can be arranged as a side corner 153 at one end (with) Figure 8 Based on the reference, the upper left corner) is in close contact with the outer peripheral surface (or, the first curved surface) of the connecting part 113, and can be arranged such that the other side (or, the upper right side) of one end contacts the inner peripheral surface of the insertion part 14c.

[0157] The first sealing member 150 can be formed using a soft material. For example, the first sealing member 150 can be made of soft rubber or silicone, and it contacts the inner peripheral surface of the insertion portion 14c, thereby preventing foreign objects such as dust from flowing into the interior.

[0158] Furthermore, the second component 152 can protrude from the other side of the first component 151 and be supported by the inner circumferential surface of the insertion portion 14c together with the first component 151.

[0159] Furthermore, a second sealing member 160 may be additionally arranged between the insertion portion 14c and the connecting portion 113 on the lower side of the first sealing member 150.

[0160] The second sealing member 160 may include a third member 161 and a fourth member 162. The second sealing member 160 may support the first sealing member 150 on the underside of the first sealing member 150 so that the first sealing member 150 is located between the insertion portion 14c and the connecting portion 113, or keep the first sealing member 150 in close contact with the connecting portion 113.

[0161] The second sealing member 160 can be formed using a rigid material. For example, the second sealing member 160 can be constructed using an injection molded material made of rubber or synthetic material that is relatively rigid compared to the first sealing member 150.

[0162] The third component 161 can be arranged to face the first curved surface, which is the outer peripheral surface of the connecting portion 113, inside the first component 151. The surface of the third component 161 facing the first curved surface of the connecting portion 113 can be formed as a curved surface corresponding to the shape of the first curved surface.

[0163] Furthermore, the fourth component 162 can extend from and bend from the third component 161 to support the third component 161 from the base 11. At this time, the fourth component 162 may have a fastening groove 163 formed on its upper surface adjacent to the third component 161 for at least a portion of the other end of the first component 151 to be inserted.

[0164] The fastening groove 163 can be arranged on the upper surface of the fourth component 162 along the circumferential direction of the first sealing component 150.

[0165] Therefore, the second sealing member 160 can support the first sealing member 150 while preventing the first sealing member 150 from disengaging from the area between the connecting part 113 and the insertion part 14c.

[0166] The first sealing member 150 and the second sealing member 160 can also be integrally formed by an insert molding method. In other words, by making the first sealing member 150 and the second sealing member 160 integral, the corner 153 of the first sealing member 150, which is made of soft material, can be in close contact with the connecting portion 113, thereby preventing external foreign matter from flowing into the space between the connecting portion 113 and the base cover 14. When the first sealing member 150 and the second sealing member 160 are integrally formed, the first sealing member 150 can be arranged to contact the connecting portion 113, and the second sealing member 160 can be arranged to be spaced apart from the connecting portion 113 by a predetermined interval rather than in direct contact.

[0167] Although not shown, the first component 151 of the first sealing component 150 and the third component 161 of the second sealing component 160 may be equipped with a first protrusion (not shown) projecting toward the outer peripheral surface of the connecting portion 113. The first protrusion may project in more than one annular manner along the circumferential direction of the first component 151 or the third component 161. That is, the first protrusion may induce line contact between the first curved surface of the connecting portion 113 and the first sealing component 150 or the second sealing component 160.

[0168] Alternatively, although not shown, the first part 151 of the first sealing member 150 and the third part 161 of the second sealing member 160 may be equipped with a second protrusion (not shown) protruding toward the outer peripheral surface of the connecting portion 113. The second protrusion may also protrude in a set dot pattern toward the first curved surface of the connecting portion 113 and be supported in a point-to-point contact manner.

[0169] The insertion portion 14c and the connecting portion 113 can restrict the relative rotation of the mirror housing 110 within a set angular range. Of course, the lower part of the lower housing 111, which is adjacent to the connecting portion 113 and the lower housing 111, is preferably designed not to contact the upper front end of the insertion portion 14c.

[0170] Furthermore, the upper housing 112 can be combined to cover the upper part of the lower housing 111. Multiple first hooks 117 can be disposed in the edge region of the upper housing 112, and a first engaging portion 116 for engaging the first hooks 117 can be disposed in the edge region of the lower housing 111, thereby allowing the upper housing 112 and the lower housing 111 to be fastened to each other in a snap-fit ​​manner. Of course, the upper housing 112 and the lower housing 111 can also be combined using a protrusion, groove, or thread, etc. Therefore, the receiving space 114 inside the mirror housing 110, in the state where the lower housing 111 and the upper housing 112 are combined, can be equipped with a drive mechanism 200 for a vehicle rearview mirror.

[0171] Furthermore, the back plate 130 and the reflective part 120 can be first joined together and then joined together in the open area of ​​the mirror housing 110 when the lower housing 111 and the upper housing 112 are joined.

[0172] A detailed description of the connection between the lower housing 111 and the base 11 via the drive unit 200 for the vehicle rearview mirror will be provided later.

[0173] Furthermore, the reflector 120 can be sandwiched between the lower housing 111 and the upper housing 112 and illuminate the light reflected from the side or rear of the vehicle 10 toward the driver.

[0174] Furthermore, the back plate 130 can be positioned within the lower housing 111 or the upper housing 112, closer to the back of the reflective portion 120. The back plate 130 may be provided with a plurality of second snap-fit ​​portions 121 to engage with second hooks 115 disposed at the edges of the open areas of the upper housing 112 and the lower housing 111, thereby allowing the back plate 130 and the mirror housing to be fastened in a snap-fit ​​manner.

[0175] The back panel 130 can form a through hole 122 with an illuminated area. When changing direction, the through hole 122 is illuminated based on the distance information of surrounding vehicles, providing assistance to the driver.

[0176] The reflective part 120 and the back plate 130 can be attached by double-sided tape (not shown). Of course, in addition to double-sided tape, the back plate 130 and the reflective part 120 can also be attached to each other by known attachment methods.

[0177] Furthermore, the frame 140 can surround the outer contour of the front surface of the reflective part 120 and the outer contour area of ​​the back plate 130 while being tightly attached to the front end of the mirror housing 110. The frame 140 can be fastened to the reflective part 120 from the front of the back plate 130 in a snap-fit ​​manner.

[0178] Therefore, the mirror housing 110, the reflective part 120, the back plate 130 and the frame 140 can be folded and rotated or tilted and rotated simultaneously with the fixing part 17 as the center.

[0179] Figure 9 This is a perspective view showing the driving device of the vehicle rearview mirror inside the vehicle rearview mirror assembly according to a first embodiment of the present invention. Figure 10 It is to separate and show Figure 9 The diagram shown is an exploded perspective view of the drive mechanism for a vehicle's rearview mirror. Figure 11 and Figure 12 It shows the removal Figure 10 A perspective view of the state of the motor housing of the drive unit for a vehicle rearview mirror.

[0180] Reference Figures 9 to 12 According to the first embodiment of the present invention, the vehicle rearview mirror assembly 100 may internally include a vehicle rearview mirror drive device 200.

[0181] The drive unit 200 may include a motor housing 210 disposed inside the mirror housing 110, and a drive unit 200 that participates in the mirror housing 110 (see reference 200). Figure 6 The components include a first drive unit 220 for folding and rotating, a tilting and rotating unit 230, a second drive unit 240 for tilting and rotating the tilting and rotating unit 230, a fixing module 250 disposed on the fixing unit 17, and a control module 270.

[0182] First, the motor housing 210 may include a lower housing 211 and an upper housing 212.

[0183] The lower housing 211 can be located inside the lower outer housing 111, and the upper housing 212 can be attached to the upper part of the lower housing 211 while forming the motor housing 210. In this case, the motor housing 210 can be located inside the mirror housing 110, but not attached to the mirror housing 110, only forming a connection at the fixing part. For example, the first drive unit 220 can be connected to a first rotation axis RA1 formed on the fixing part 17 (see reference). Figure 15 The motor housing 210 is provided with a central motor housing 210 for relative rotation with respect to the fixed module 250 to provide folding drive for the mirror housing 110. The second drive unit 240 can be positioned relative to the second rotation axis RA2 (see reference 230) formed between the motor housing 210 and the tilting rotation unit 230. Figure 5 The relative rotation is provided to the tilting rotation section 230 to provide tilting drive for the mirror housing 110.

[0184] Furthermore, the first drive unit 220 may include a first motor 221 and a first gear module 222, and may rotate according to the rotation of the first motor 221 with the final output of the first gear module 222.

[0185] The first gear module 222 may include a first worm gear 223 and a first reduction gear 224.

[0186] The first worm gear 223 can be coupled to the rotating shaft of the first motor 221. The first worm gear 223 can transmit rotational force to the first reduction gear 224.

[0187] The first reduction gear 224 can mesh with the first worm gear 223, and can have a rotating shaft arranged in a direction different from the rotating shaft of the first worm gear 223. The first reduction gear 224 can provide a set gear ratio and is composed of multiple first gears 224a and second gears 224b that rotate simultaneously.

[0188] Therefore, the final output of the first gear module 222 can be transmitted to the first reduction gear 224, and the first reduction gear 224 can mesh with the driven gear 251 of the fixed module 250 that meshes with the second gear 224b, and the motor housing can rotate relative to the driven gear 251.

[0189] Furthermore, the tilting and rotating part 230 may include a first cover 231, a second cover 232, and a third cover 233.

[0190] The first cover 231 can be arranged to cover the upper part of the upper housing 212.

[0191] The second cover 232 may extend from one side of the first cover 231 to face one side surface of the lower housing 211.

[0192] The third cover 233 can extend from the other side of the first cover 231 to face one 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 arranged in opposite directions based on the motor housing 210. The third cover 233 can be formed with a slit 234 that is curved along the radius of rotation of the inclined rotating part 230. A portion of the second drive part 240, which will be described later, can be installed in the slit 234.

[0193] The first cover 231 can be combined with the upper housing 212 or the lower housing 211.

[0194] For example, such as Figure 9 As shown, the drive unit 200 may further include a clamping device between the tilting rotating part 230 and the upper housing 112 (see reference). Figure 8 The tilting rotating part 230 is attached to the fixed frame 260 of the mirror housing 110. After the central region of the fixed frame 260 is fastened to the upper part of the first cover 231, the outer edge region is fastened and fixed to the lower housing 111, so that the tilting rotating part 230 can be arranged to tilt relative to the motor housing 210 together with the mirror housing 110.

[0195] Furthermore, the second drive unit 240 may include a second motor 241, a second gear module 242, a first shaft 243, and a second shaft 244.

[0196] The second gear module 242 may include a second worm gear 245 and a second reduction gear 246.

[0197] The second worm gear 245 can be coupled to the rotating shaft of the second motor 241. The second worm gear 245 can transmit rotational force to the second reduction gear 246.

[0198] The second reduction gear 246 can mesh with the second worm gear 245, and can have a rotating shaft arranged in a direction different from the rotating shaft of the second worm gear 245. The second reduction gear 246 can provide a set gear ratio and is composed of multiple gears rotating simultaneously.

[0199] Furthermore, the second drive unit 240 may additionally include a third reduction gear 247 that meshes with the second reduction gear 246. In this case, the second reduction gear 246 and the third reduction gear 247 can provide different gear ratios to each other. The third reduction gear 247 can transmit the final output to the first shaft 243.

[0200] Furthermore, the fixing module 250 can elastically support the motor housing 210 on the fixing part.

[0201] The fixed module 250 may include a driven gear 251, a clamping plate 252, a clamp 253, an elastic component 254, and a secondary gear 255.

[0202] The driven gear 251 can be fastened inside the motor housing 210 so that the fixing part 17 passes through the interior. Although the driven gear 251 is engaged and fixed to the fixing part 17 and does not rotate, 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, thereby enabling folding rotation. That is, the driven gear 251 can be fixed to the fixing part 17, and the first reduction gear 224 can rotate with the driven gear 251.

[0203] Furthermore, the clamp 252 can be fixed by the clamp 253 at the front end of the fixing part 17.

[0204] Furthermore, the elastic component 254 can provide elastic support between the driven gear 251 and the clamping plate 252.

[0205] Furthermore, the secondary gear 255 can be arranged to surround the outer side of the elastic member 254, and can be placed on the driven gear 251 to rotate simultaneously with the driven gear 251. Gear teeth can be formed on the outer peripheral surface of the secondary gear 255 to mesh with a part of the control module 270, which will be described later, and the folded rotation state of the motor housing 210 relative to the secondary gear 255 can be transmitted to the control module 270.

[0206] Furthermore, the control module 270 may include a substrate 271, a first potentiometer 272 for sensing the rotation of the first drive unit 220, and a second potentiometer 273 for sensing the rotation of the second drive unit 240.

[0207] The first potentiometer 272 and the second potentiometer 273 can be respectively disposed on the substrate 271. Each potentiometer 272, 273 can be implemented by a variable resistor that converts linear displacement or rotational displacement into a change in resistance. Such potentiometers 272, 273 can be configured as contact type or non-contact type; in this embodiment, a contact type configuration is described as an example. The contact type potentiometer, as a brush moving resistor structure, can measure displacement based on the rotation angle or the number of rotations.

[0208] The first potentiometer 272 may be configured with a first gear 274 arranged rotatably on the substrate 271, and the first gear 274 may be arranged to mesh with the gear tooth profile 256 of the secondary gear 255. Therefore, the folding rotation angle of the motor housing 210 can be calculated based on the rotation angle of the first gear 274 relative to the gear tooth profile 256 of the secondary gear 255.

[0209] The second potentiometer 273 may be equipped with a second gear 275 arranged to be rotatable on the substrate 271, and the second gear 275 may be arranged to mesh with the gear teeth disposed on the inclined worm gear 249. Therefore, the tilt rotation angle of the inclined rotating part 230 can be calculated based on the rotation angle of the second gear 275 relative to the inclined worm gear 249 with the first shaft 243 as the center.

[0210] Figure 13 It is shown Figure 10 The diagram shows the connection position of the tilting and rotating part of the drive mechanism for a vehicle rearview mirror. Figure 14 It is shown Figure 10 The diagram shows the process of tilting the tilting rotating part of the drive device for a vehicle rearview mirror.

[0211] Reference Figure 13 and Figure 14 The first shaft 243 transmits rotational force based on tilting rotation to the second cover 232 through one side surface of the lower housing 211.

[0212] The third worm gear 248 and the inclined worm gear 249 can be coupled to the first shaft 243 in a manner that allows them to rotate simultaneously. The third worm gear 248 can mesh with the third reduction gear 247 to transmit output to the first shaft 243.

[0213] The tilting worm gear 249 can be arranged to rotate within a limited angle range as the first shaft 243 rotates.

[0214] At this time, the outer end of the first shaft 243 is connected to the second cover 232. As the first shaft 243 rotates, the tilting rotating part 230 can rotate within a limited range of angles.

[0215] Furthermore, the second shaft 244 can be inserted into the slit 234 of the third cover 233 by penetrating one side surface of the upper housing 212. Therefore, the angle or length by which the tilting rotating part 230 rotates or moves from the second shaft 244 can be limited according to the angle or length of the slit 234.

[0216] Figure 15 and Figure 16 It is shown Figure 10 The diagram shows the folded or tilted state of the drive mechanism of the vehicle's rearview mirror.

[0217] Reference Figure 15 and Figure 16 At base 11 (refer to) Figure 8 On the mirror casing 110 (refer to) Figure 7The first rotating shaft RA1, where the motor housing 210 is folded, can be arranged on a virtual extension line of the second rotating shaft RA2, where the tilting rotating part 230 is tilted. For example, the second rotating shaft RA2, formed at the rotation center of the first shaft 243, can be arranged to overlap with the first rotating shaft RA1 in the axial direction.

[0218] That is, the motor housing 210 and the mirror housing 110 can be folded and rotated simultaneously with the first rotation axis RA1, which is the rotation center of the fixed part 17, as the center of rotation. Since the second rotation axis RA2 is located on the motor housing 210, the mirror housing 110 can be tilted and rotated relative to the motor housing 210 together with the tilting rotation part 230 within a set angle range.

[0219] Furthermore, by designing the gear ratio of the first gear module 222 when the mirror housing 110 is folded and rotated, and the gear ratio of the second gear module 242 when it is tilted and rotated, it is possible to achieve a uniformity between the folding speed and the tilting speed. For example, by setting the gear ratio of the first gear module 222 to 1500 and the gear ratio of the second gear module 242 to 1500, it is possible to ensure that the start and end times of the folding and tilting rotations are similar to each other.

[0220] Therefore, the vehicle rearview mirror assembly according to an embodiment of the present invention has the following effects: since the mirror and the mirror housing together achieve rotation based on folding or tilting, the edge line of the mirror outline can be minimized, and the cost can be reduced by simplifying the configuration of the first drive unit for folding the mirror housing and the second drive unit for tilting the mirror housing. Through the optimization of the drive unit components, the degree of freedom to improve according to the mirror design can be ensured.

[0221] Figure 17 This is a perspective view showing the driving device of the vehicle rearview mirror inside the vehicle rearview mirror assembly according to a second embodiment of the present invention. Figure 18 It is to separate and show Figure 17 The diagram shown is an exploded perspective view of the drive mechanism for a vehicle's rearview mirror. Figure 19 It is shown Figure 17 The diagram shows a longitudinal sectional view of the drive mechanism for a vehicle rearview mirror.

[0222] Reference Figures 17 to 19 According to a second embodiment of the present invention, the vehicle rearview mirror assembly 100 may internally include a vehicle rearview mirror drive device 1200.

[0223] The drive unit 1200 includes a motor housing 1210 disposed inside the mirror housing 110, and a drive unit 1200 (see reference 1210). Figure 6The components include a first drive unit 1220 for folding and rotating, a tilting and rotating unit 1230, a second drive unit 1240 for tilting and rotating the tilting and rotating unit 1230, a fixing module 1250 disposed on the fixing unit 17, and a control module 1270 (see reference). Figure 25 ).

[0224] First, the motor housing 1210 may include a lower housing 1211 and an upper housing 1212.

[0225] The lower housing 1211 can be located on the lower outer shell 111 (see reference). Figure 8 The upper housing 1212 can be attached to the upper part of the lower housing 1211 to form the motor housing 1210. In this case, the motor housing 1210 can be located inside the mirror housing 110, but not attached to it; it is only attached to the fixing part. For example, the first drive unit 1220 can be connected to the first rotation axis RA1 formed in the fixing part 17 (see reference 1211). Figure 25 The motor housing 1210 is provided with a folding drive for the mirror housing 110 by relative rotation with respect to the fixed module 1250. The second drive unit 1240 can be positioned relative to the second rotation axis RA2 (see reference 1250) formed between the motor housing 1210 and the tilting rotation unit 1230. Figure 25 The relative rotation is provided to the tilting rotation part 1230 to provide tilting drive for the mirror housing 110.

[0226] The lower housing 1211 may include a cylindrical portion 1213 and an inclined shaft fastening portion 1214.

[0227] The cylindrical portion 1213 can protrude downward from one side of the lower housing 1211 and can be configured in a cylindrical shape to surround the fixing portion 17 when the fixing portion 17 is inserted into the center.

[0228] Furthermore, a support member 1215 can be additionally fastened around the cylindrical portion 1213. The support member 1215 is fastened around the cylindrical portion 1213, and a portion of the tilting rotating portion 1230 is sandwiched between the lower housing 1211 and the support member 1215, while supporting one side of the tilting rotating portion 1230.

[0229] The support member 1215 may include a guide member 1216 that guides the direction of engagement with the lower housing 1211 to an accurate position. The guide member 1216 may be formed using one or more protrusions and groove structures facing the lower part of the lower housing 1211. In this embodiment, an example is shown where the guide member 1216 with groove structures arranged in a straight line is disposed on the upper surface of the support member. Of course, a protrusion 1213a structure of a corresponding shape may be formed on the outer peripheral surface of the cylindrical portion 1213 of the lower housing 1211. Therefore, the engagement direction of the support member 1215 with the lower housing 1211 can be set by the guide member 1216. Furthermore, the guide member 1216 and the protrusion 1213a may be disturbed along the folding rotation direction, causing the support member 1215 and the cylindrical portion 1213 to rotate together when the motor housing 1210 is folded and rotated.

[0230] Furthermore, the support member 1215 may include a pair of support ends 1217 protruding toward the bottom surface of the lower housing 1211. The support ends 1217 may be arranged spaced apart from each other along the axial direction of the second rotation axis RA2 with the cylindrical portion 1213 as the center, thereby rotatably supporting one side of the tilting rotating portion 1230, which will be described later.

[0231] The support member 1215 can be arranged to rotate from the fixing part 17 as the folding rotation occurs. At this time, a bushing 1218 can be additionally provided in the area where the support member 1215 and the fixing part 17 are in contact with each other.

[0232] Furthermore, the tilting shaft fastener 1214 can support the other side of the tilting rotating part 1230 from the other side of the lower housing 1211. The tilting shaft fastener 1214 can be fastened to the shaft 1243 disposed on the second rotating shaft RA2 of the lower housing 1211, and the tilting rotating part 1230 can be rotatably fastened to the shaft 1243 with the second rotating shaft RA2 as the center.

[0233] Furthermore, the tilting rotation unit 1230 can be configured to rotate relative to a second rotation axis RA2 (or tilting rotation axis) formed at the lower center of the motor housing 1210. Of course, the tilting rotation unit 1230 can be driven by the second drive unit 1240 to rotate from the motor housing 1210 in the tilting direction. In this case, the tilting rotation unit 1230 can rotate together with the mirror housing 110 and the reflector 120 around the second rotation axis RA2.

[0234] The tilting and rotating part 1230 may include a bottom surface 1231, a first support part 1232, a second support part 1233, and a side wall 1234.

[0235] The bottom surface 1231 can be arranged to face and be spaced apart from the bottom surface of the lower housing 1211. The bottom surface 1231 and the lower housing 1211 can be arranged to be spaced apart from each other for relative rotation according to their tilting rotation.

[0236] Furthermore, the first support portion 1232 and the second support portion 1233 can be arranged on the bottom surface 1231 separately from each other.

[0237] The first support portion 1232 can support one side of the bottom surface with the second rotation axis RA2 as the center, and the second support portion 1233 can support the other side of the bottom surface 1231 with the second rotation axis RA2 as the center.

[0238] The first support portion 1232 may include a pair of support plates 1235 spaced apart from each other along the second rotation axis RA2 with the cylindrical portion 1213 as the center. Each support plate 1235 may be arranged on each support end 1217 of the support member 1215 and may be arranged to be in surface contact with each other.

[0239] Furthermore, the sidewall 1234 can be arranged to face the two side surfaces of the lower housing 1211, and can be arranged to surround the lower housing 1211.

[0240] Therefore, the tilting rotating part 1230 can be arranged to tilt and rotate on the lower housing 1211 about the second rotation axis RA2.

[0241] Furthermore, the tilting and rotating part 1230 can be fastened together with the fixed frame 1260 to the mirror housing 110 (see reference). Figure 6 Inside the mirror housing 110. Although the tilting rotating part 1230 is only fastened to the lower housing 1211, with the further configuration of the fixing frame 1260, the tilting rotating part 1230 can be firmly fastened to the upper housing 112 and the back plate 130 via the fixing frame 1260. Of course, the fixing frame 1260 can tilt and rotate together with the mirror housing 110 around the second rotation axis RA2, and can more firmly support the support structure that rotates the tilting rotating part 1230 inside the mirror housing 110.

[0242] Furthermore, a detailed description of the fixed module 1250 and the control module 1270 will be provided later.

[0243] Figure 20 and Figure 21 It is shown Figure 17 A perspective view showing the tilting and rotating part of the drive mechanism for a vehicle's rearview mirror in its rotating state. Figure 22 It is shown Figure 17 A perspective view of the side surface of the tilting and rotating part of the vehicle rearview mirror drive unit, showing its rotation relative to the motor housing. Figure 23 It is shown Figure 17 The reference diagram shows the combined state of the lower housing of the drive unit of the vehicle rearview mirror and the tilting rotating part on the second support.

[0244] Reference Figures 20 to 23 The lower housing 1211 may include a support guide 1219 protruding from one side surface.

[0245] The support guide 1219 can be arranged to overlap with the support end 1217 or the support piece 1235 relative to the vertical direction. The bottom surface of the support guide 1219 can be arranged to contact the upper surface of the support piece 1235. In this case, the bottom surface of the support guide 1219 and the upper surface of the support piece 1235 can be formed as a second curved surface to support relative rotation between them.

[0246] The support guide 1219 may have first planes formed on both sides of the second curved surface opposite to the support piece 1235. In this case, the support piece 1235 may have second planes that selectively contact the first planes. The second planes may be formed on both sides of the second curved surface of the support piece 1235. Therefore, when the support guide 1219 and the support piece 1235 contact the first and second planes respectively, the rotation range of the tilting rotating part 1230 can be limited.

[0247] The contact surfaces of each support piece 1235 and support end 1217 can be formed as first curved surfaces facing each other, and can simultaneously realize the support structure and the fastening structure.

[0248] Furthermore, the second support portion 1233 can be spaced apart from the first support portion 1232 along the axial direction of the second rotation axis RA2 to support the other side of the bottom surface 1231. The second support portion 1233 can be arranged to be fastened to the shaft 1243 of the inclined shaft fastening portion 1214 through the interior, and can also be connected in a tiltable and rotatable manner.

[0249] Furthermore, the tilting rotating part 1230 may have a groove 1234a formed inside the side wall 1234, and a protrusion 1211a may be formed on the side surface of the lower housing 1211 opposite to the side wall 1234. Although not shown in the figures, the protrusion may be formed inside the side wall, and the groove may be formed on the side surface of the lower housing.

[0250] At this time, the protrusion 1211a and the groove 1234a can be arranged in corresponding positions to make contact before the side wall 1234 and the side surface of the lower housing 1211 come into contact with each other, thereby limiting the range of relative rotation of the tilting rotating part 1230 relative to the lower housing 1211.

[0251] Of course, the protrusion 1211a and the groove 1234a can be respectively arranged on both sides of the lower housing 1211 and the tilting rotating part 1230, thereby limiting the rotation range of the tilting rotating part 1230 in both directions.

[0252] The inclined shaft fastening part 1214 may be formed with a fastening groove 1214a with an undercut shape so that both ends of the shaft 1243 are pressurized and fixed. That is, the inclined shaft fastening part 1214 is detachably connected to the shaft 1243.

[0253] Figure 24 It shows the removal Figure 17 The diagram shows the state of the upper housing of the drive unit for a vehicle rearview mirror. Figure 25 It is to decompose and show Figure 24 An exploded perspective view of the first and second drive units of the vehicle rearview mirror drive mechanism shown. Figure 26 It is shown in magnification Figure 24 A perspective view of the first drive unit of the vehicle rearview mirror drive mechanism shown. Figure 27 It is shown in magnification Figure 25 A perspective view of the second drive unit of the vehicle rearview mirror drive mechanism shown.

[0254] The first drive unit 1220 may include a first motor 1221 and a first gear module 1222, and can rotate according to the rotation of the first motor 1221 and the final output of the first gear module 1222.

[0255] The first gear module 1222 may include a first worm gear 1223 and a first reduction gear 1224.

[0256] The first worm gear 1223 can be coupled to the rotating shaft of the first motor 1221. The first worm gear 1223 can transmit rotational force to the first reduction gear 1224.

[0257] The first reduction gear 1224 can mesh with the first worm gear 1223, and can have a rotating shaft arranged in a direction different from the rotating shaft of the first worm gear 1223. The first reduction gear 1224 provides a set gear ratio and is composed of multiple first gears 1224a and second gears 1224b that rotate simultaneously.

[0258] Therefore, the final output of the first gear module 1222 can be transmitted to the first reduction gear 1224, and the first reduction gear 1224 can mesh with the driven gear 1251 of the fixed module 1250 that meshes with the second gear 1224b, and the motor housing can rotate relative to the driven gear 1251.

[0259] Furthermore, the second drive unit 1240 may include a second motor 1241, a second gear module 1242, and a shaft 1243.

[0260] The second gear module 1242 may include a second worm gear 1245 and a second reduction gear 1246.

[0261] The second worm gear 1245 can be coupled to the rotating shaft of the second motor 1241. The second worm gear 1245 can transmit rotational force to the second reduction gear 1246.

[0262] The second reduction gear 1246 can mesh with the second worm gear 1245, and can have a rotating shaft arranged in a direction different from the rotating shaft of the second worm gear 1245. The second reduction gear 1246 provides a set gear ratio and is constructed using multiple gears that rotate simultaneously.

[0263] Furthermore, the second drive unit 1240 may include a third reduction gear 1247 that meshes with the second reduction gear 1246. In this case, the second reduction gear 1246 and the third reduction gear 1247 can provide different gear ratios. The third reduction gear 1247 can transmit the final output to the shaft 1243 connected to the third worm gear 1248.

[0264] Furthermore, the fixing module 1250 can elastically support the motor housing 1210 on the fixing part.

[0265] The fixed module 1250 may include a driven gear 1251, a clamping plate 1252, a clamp 1253, an elastic member 1254, and a secondary gear 1255.

[0266] Driven gear 1251 can be fastened inside the motor housing 1210 so that the fixing part 17 passes through the interior. Although driven gear 1251 is engaged and fixed to the fixing part 17 and does not rotate, the rotational force transmitted from the first reduction gear 1224 to driven gear 1251 can cause the motor housing 1210 to rotate relative to driven gear 1251, thereby enabling folding rotation. That is, driven gear 1251 can be fixed to the fixing part 17, and the first reduction gear 1224 can rotate with driven gear 1251.

[0267] Furthermore, the clamp 1252 can be fixed by the clamp 1253 at the front end of the fixing part 17.

[0268] Furthermore, the elastic component 1254 can provide elastic support between the driven gear 1251 and the clamping plate 1252.

[0269] Furthermore, the secondary gear 1255 can be arranged to surround the outer side of the elastic member 1254 and can be placed on the driven gear 1251. Gear teeth can be formed on the outer peripheral surface of the secondary gear 1255 to mesh with a part of the control module 1270, which will be described later. The folded rotation state of the motor housing 1210 relative to the secondary gear 1255 can be transmitted to the control module 1270.

[0270] Furthermore, the control module 1270 may include a substrate 1271, a first potentiometer 1272 for sensing the rotation of the first driving unit 1220, and a second potentiometer 1273 for sensing the rotation of the second driving unit 1240.

[0271] The first potentiometer 1272 and the second potentiometer 1273 can be respectively disposed on the substrate 1271. Each potentiometer 1272 and 1273 can be implemented by a variable resistor that converts linear or rotational displacement into a change in resistance. Such potentiometers 1272 and 1273 can be configured as contact type or non-contact type. In this embodiment, a contact type configuration is described as an example. The contact type potentiometer has the structure of a brush moving resistor and can measure displacement according to the rotation angle or the number of rotations.

[0272] The first potentiometer 1272 may be configured with a first gear 1274 arranged rotatably on the substrate 1271, and the first gear 1274 may be arranged to mesh with the gear teeth of the secondary gear 1255. Therefore, the folding rotation angle of the motor housing 1210 can be calculated based on the rotation angle of the first gear 1274 relative to the gear teeth of the secondary gear 1255.

[0273] The second potentiometer 1273 may be equipped with a second gear 1275 arranged rotatably on the substrate 1271, and the second gear 1275 may be arranged to mesh with the gear teeth disposed on the inclined worm gear 1249. Therefore, the tilt rotation angle of the inclined rotating part 1230 can be calculated based on the rotation angle of the second gear 1275 about the shaft 1243 relative to the inclined worm gear 1249.

[0274] Shaft 1243 can be engaged with third worm gear 1248 and inclined worm gear 1249 in a manner that allows them to rotate simultaneously. Third worm gear 1248 can mesh with third reduction gear 1247 to transmit output to shaft 1243. Third worm gear 1248 and inclined worm gear 1249 can be formed as a single unit.

[0275] The tilting worm gear 1249 can be arranged to rotate within a limited angle range as the shaft 1243 rotates.

[0276] Therefore, the drive device for a vehicle rearview mirror according to an embodiment of the present invention has the following effects: by constructing a first drive unit for folding and a second drive unit for tilting into a package, the size can be reduced while the cost is lowered; and by encapsulating the drive module, the degree of freedom for improving the mirror design can be ensured; the range of rotation of the tilting rotation unit on the motor housing can be limited to a set range; and by improving the connection structure of the tilting rotation unit inside the mirror housing with the drive device as the center, a robust support structure based on tilting rotation can be provided.

[0277] Figure 28 This is a perspective view showing the driving device of the vehicle rearview mirror inside the vehicle rearview mirror assembly according to a third embodiment of the present invention. Figure 29 It is to separate and show Figure 28 The diagram shown is an exploded perspective view of the drive mechanism for a vehicle's rearview mirror. Figure 30 It is shown Figure 28 The diagram shows a longitudinal sectional view of the drive mechanism for a vehicle rearview mirror along section A-A'. Figure 31 It is shown Figure 28 The diagram shows a longitudinal section of the drive mechanism for a vehicle rearview mirror, section B-B'.

[0278] Reference Figures 28 to 31 The vehicle rearview mirror assembly 100 according to the present invention may internally include a vehicle rearview mirror drive device 2000.

[0279] The drive unit 2000 may include a motor housing 2210 disposed inside the mirror housing 110, and a drive unit 2210 connected to the mirror housing 110 (see reference 110). Figure 6 The components include a first drive unit 2220 for folding and rotating, a tilting and rotating unit 2230, a support member 2215, a second drive unit 2240 for tilting and rotating the tilting and rotating unit 2230, a fixing module 2250 disposed on the fixing unit 17, a control module 2270, and a motor setting unit 2280.

[0280] First, the motor housing 2210 may include a lower housing 2211 and an upper housing 2212.

[0281] The lower housing 2211 can be located inside the lower outer housing 111, and the upper housing 2212 can be attached to the upper part of the lower housing 2211 to form the motor housing 2210. In this case, the motor housing 2210 can be located inside the mirror housing 110, but is not attached to the mirror housing 110, but is only attached to the fixing part 17. For example, the first drive part 2220 can provide a folding drive for the mirror housing 110 by providing relative rotation of the motor housing 2210 relative to the fixing module 2250 with the first rotation axis RA1 formed in the fixing part 17 as the center, and the second drive part 2240 can provide relative rotation of the mirror housing 110 by driving a tilting rotation relative to the tilting rotation part 2230 with the second rotation axis RA2 formed between the motor housing 2210 and the tilting rotation part 2230.

[0282] The lower housing 2211 may include a cylindrical portion 2213, an inclined shaft fastening portion 2214, a first mounting portion 2218a, a second mounting portion 2218b, and a third mounting portion 2218c.

[0283] The cylindrical portion 2213 can protrude downward from one side of the bottom surface of the lower housing 2211, and can be configured as a hollow cylindrical shape to surround the fixing portion 17 when the fixing portion 17 is inserted into the center.

[0284] A first reduction gear 2224 (described later) can be installed in the first mounting part 2218a, a second reduction gear 2246 can be installed in the second mounting part 2218b, and a motor mounting part 2280 can be installed in the third mounting part 2218c. The first mounting parts 2218a to the third mounting parts 2218c can be formed inside the lower housing 2211 to increase the assemblability of the first reduction gear 2224, the second reduction gear 2246, the third reduction gear 2247, and the motor mounting part 2280.

[0285] Furthermore, a support member 2215 can be additionally fastened to the periphery of the cylindrical portion 2213 via the fixing part 17. The support member 2215 can be fastened to the periphery of the cylindrical portion 2213, thereby supporting a portion of the tilting rotating portion 2230 (or the first support piece 2235) between the lower housing 2211 and the support member 2215.

[0286] The support member 2215 may include a guide member 2216 that guides the direction of engagement with the lower housing 2211 to an accurate position. The guide member 2216 may be formed using one or more protrusions and grooves facing the lower part of the lower housing 2211. In this embodiment, an example is shown where the guide members 2216 are arranged parallel to each other on both sides, forming grooves on the support member 2215 facing each other in opposite directions. Of course, a first protrusion 2213a structure of a corresponding shape may be formed on the outer peripheral surface of the cylindrical portion 1213 of the lower housing 2211. Therefore, the engagement direction of the support member 2215 with the lower housing 2211 can be set by the guide member 2216. Furthermore, the guide member 2216 and the first protrusion 2213a may be disturbed along the folding rotation direction, causing the support member 2215 and the cylindrical portion 2213 to rotate together when the motor housing 2210 is folded and rotated.

[0287] Furthermore, the support member 2215 may include a pair of support ends 2217 protruding toward the bottom surface of the lower housing 2211 (or, the first support piece 2235). The support ends 2217 may be arranged at the lower part of the first support piece 2235 with the cylindrical portion 2213 as the center along the axial direction of the second rotation axis RA2, thereby rotatably supporting one side of the tilting rotating portion 2230, which will be described later.

[0288] When folded and rotated, the support member 2215 can be arranged to be rotatable on the fixing part 17. At this time, a bushing (not shown) can be additionally provided in the area where the support member 2215 and the fixing part 17 are in contact with each other.

[0289] Furthermore, the tilting shaft fastener 2214 can support the other side of the tilting rotating part 2230 from the other side of the bottom surface of the lower housing 2211. The tilting shaft fastener 2214 can be fastened to the shaft 2243 arranged on the second rotating shaft RA2 of the lower housing 1211, and the tilting rotating part 2230 can be rotatably coupled to the shaft 2243 with the second rotating shaft RA2 as the center.

[0290] Furthermore, the tilting rotation unit 2230 can be arranged to rotate relative to the second rotation axis RA2 (or tilting rotation axis) formed at the lower center of the motor housing 2210. Of course, the tilting rotation unit 2230 can be driven by the second drive unit 2240 to rotate from the motor housing 2210 in the tilting direction. In this case, the tilting rotation unit 2230 can rotate together with the mirror housing 110 and the reflective unit 120 around the second rotation axis RA2.

[0291] The tilting and rotating part 2230 may include a bottom surface 2231, a first support part 2232, and a second support part 2233 (see reference). Figure 34) and sidewalls 2234.

[0292] The bottom surface 2231 can be arranged to face and be spaced apart from the bottom surface of the lower housing 2211. The bottom surface 2231 and the lower housing 2211 can be arranged to be spaced apart from each other for relative rotation according to their tilting rotation.

[0293] Furthermore, the first support portion 2232 and the second support portion 2233 can be arranged on both sides of the bottom surface 1231, spaced apart from each other.

[0294] The first support portion 2232 can support one side of the bottom surface with the second rotation axis RA2 as the center, and the second support portion 2233 can support the other side of the bottom surface 2231 with the second rotation axis RA2 as the center.

[0295] The first support portion 2232 may include a pair of support plates 2235 spaced apart from each other along the second rotation axis RA2 with the cylindrical portion 2213 as the center. Each support plate 2235 may be arranged on each support end 2217 of the support member 2215 and may be arranged to be in surface contact with each other.

[0296] Furthermore, the sidewall 2234 can be arranged to face the two side surfaces of the lower housing 2211, and can be arranged to surround the lower housing 2211.

[0297] Therefore, the tilting rotating part 2230 can be arranged to tilt and rotate on the lower housing 2211 about the second rotation axis RA2.

[0298] Furthermore, the tilting rotation unit 2230 may have a tilting worm gear 2249 disposed on its bottom surface 2231. The tilting worm gear 2249 may provide the second potentiometer 2273, which will be described later, with rotation amount data based on the tilting rotation of the tilting rotation unit 2230.

[0299] Furthermore, a gear mounting portion 2236, adjacent to the inclined worm gear 2249 and housing a third worm gear 2248 (described later), can be disposed on the bottom surface 2231 of the tilting rotating portion 2230. The gear mounting portion 2236 guides the engagement position, such that at least a portion of the main body 2248a of the third worm gear 2248 is inserted and fixed in a predetermined position. The gear teeth of the third worm gear 2248, positioned on the upper part of the main body 2248a, are exposed on the gear mounting portion 2236.

[0300] Furthermore, a guide groove 2230a can be formed on the side wall 2234 of the tilting rotation portion 2230 to guide the position where it will be joined with the mirror housing 110. The guide groove 2230a is formed as a recessed structure to accommodate the rib 118 of the lower housing 111 (see reference). Figure 6The guide groove 2230a and rib 118 are inserted to accurately guide the tilting rotating part 2230 to its designated position. This structure of the guide groove 2230a and rib 118 can provide increased assemblability by pre-assembling the tilting rotating part 2230 and the mirror housing 110.

[0301] Furthermore, the lower housing 2211 may have a first exposure hole 2214a formed in which the gear teeth of the third worm gear 2248, which is attached to the tilting rotating part 2230, are exposed to the interior of the lower housing 2211. A fixed end 2214b may be disposed around the first exposure hole 2214a of the lower housing 2211. When the gear teeth flow into the interior of the lower housing through the first exposure hole 2214a, pressure is applied from the periphery of the first exposure hole 2214a toward the gear mounting part 2236 to the upper surface of the main body 2248a or the outer contour of the gear teeth. The fixed end 2214b can firmly support the third worm gear 2248 between the gear mounting part 2236 and the lower housing 2211 to prevent flow.

[0302] Furthermore, the tilting and rotating part 2230 can be fastened to the mirror housing 110 together with the fixed frame 2260 (see reference). Figure 6 Inside the mirror housing 110. Although the tilting rotating part 2230 is only fastened to the lower housing 2211, with the further configuration of the fixing frame 2260, the tilting rotating part 2230 can be fastened to one or more of the upper housing 112 and the back plate 130 via the fixing frame 2260. Of course, the fixing frame 2260 can tilt and rotate together with the mirror housing 110 around the second rotation axis RA2, and can more firmly support the support structure for the tilting rotating part 2230 to rotate inside the mirror housing 110.

[0303] The fixing frame 2260 may include a hook component 2261 and a guide protrusion 2262.

[0304] When the tilting rotating part 2230 and the fixed frame 2260 are combined, the hook part 2261 is fastened to the side wall 2234 of the tilting rotating part 2230, so that the tilting rotating part 2230 and the fixed frame 2260 can form a temporary assembly before being fixed to each other inside the mirror housing 110.

[0305] Furthermore, the guide protrusion 2262 can be inserted into the guide groove 2230a. The guide protrusion 2262 can guide the engagement position of the tilting rotating part 2230 and the fixed frame 2260. For example, the guide protrusion 2262 and the guide groove 2230a can be arranged in different positions according to the left and right rearview mirrors of the vehicle to prevent confusion between the components used for the left and right rearview mirrors, thereby increasing assemblability. Of course, the aforementioned rib 118 or guide protrusion 2262 can be selectively inserted into the guide groove 2230a, or multiple guide grooves 2230a can be formed at different positions to accommodate the rib 118 or guide protrusion 2262 respectively.

[0306] Furthermore, detailed descriptions of the fixed module 2250, the control module 2270, and the motor setting unit 2280 will be provided later.

[0307] Figure 32 It is shown Figure 28 The diagram shows a longitudinal sectional view of the drive mechanism for a vehicle rearview mirror, section B-B'. Figure 33 It shows the tilting rotating part relative to Figure 28 The diagram shows a perspective view of the side surface of the motor housing of the vehicle's rearview mirror drive unit in a rotated state. Figure 34 It is shown Figure 28 The reference diagram shows the combined state of the lower housing of the drive unit of the vehicle rearview mirror and the tilting rotating part on the second support.

[0308] Reference Figures 32 to 34 The lower housing 2211 may include a support guide 2219 protruding from the lower side.

[0309] The support guide 2219 can be arranged to overlap the support end 2217 or the first support piece 2235 along the vertical direction. The bottom surface of the support guide 2219 can be arranged to contact the upper surface of the first support piece 2235. In this case, the bottom surface of the support guide 2219 and the upper surface of the first support piece 2235 can be formed as a second curved surface to support relative rotation (or, tilted rotation) between them.

[0310] The contact surfaces of each of the first support plate 2235 and the support end 2217 can be formed as first curved surfaces facing each other, thereby simultaneously realizing the support structure and the fastening structure.

[0311] Furthermore, the second support portion 2233 can be spaced apart from the first support portion 2232 along the axial direction of the second rotation axis RA2 to support the other side of the bottom surface 2231. The second support portion 2233 can be arranged to be fastened to the shaft 2243 of the inclined shaft fastening portion 2214 through the interior, and is fastened to the inclined shaft fastening portion 2214, and can also be tiltably and rotatably connected.

[0312] Furthermore, the tilting rotating portion 2230 may have a second protrusion 2234a formed inside the side wall 2234. The second protrusion 2234a may contact the side surface of the lower housing 2211 while the tilting rotating portion 2230 is tilting and rotating. Although not shown in the figures, a protrusion may also be formed on the outside of the lower housing 2211.

[0313] At this time, the second protrusion 2234a can limit the range of relative rotation of the tilting rotating part 2230 relative to the lower housing 2211.

[0314] Figure 35 It shows the removal Figure 28 The diagram shows the state of the upper housing of the drive unit for a vehicle rearview mirror. Figure 36 It is to decompose and show Figure 35 An exploded perspective view of the first and second drive units of the vehicle rearview mirror drive mechanism shown. Figure 37 It is shown in magnification Figure 36 A perspective view of the first drive unit of the vehicle rearview mirror drive mechanism shown. Figure 38 It is shown in magnification Figure 36 A perspective view of the second drive unit of the vehicle rearview mirror drive mechanism shown. Figure 39 It is shown Figure 36 A perspective view showing the engagement state of the auxiliary gear and driven gear of the drive mechanism for a vehicle rearview mirror.

[0315] Reference Figures 35 to 39 The first drive unit 2220 may include a first motor 2221 and a first gear module 2222, and can be folded and rotated according to the rotation of the first motor 2221 and the final output of the first gear module 2222.

[0316] The first gear module 2222 may include a first worm gear 2223 and a first reduction gear 2224.

[0317] The first worm gear 2223 can be coupled to the rotating shaft of the first motor 2221. The first worm gear 2223 can transmit rotational force to the first reduction gear 2224.

[0318] The first reduction gear 2224 can mesh with the first worm gear 2223, and can have a rotating shaft arranged in a direction different from the rotating shaft of the first worm gear 2223. The first reduction gear 2224 can provide a set gear ratio and is constructed using the simultaneously rotating first gear 2224a and second gear 2224b.

[0319] Therefore, the final output of the first gear module 2222 can be transmitted to the first reduction gear 2224, and the first reduction gear 2224 can mesh with the driven gear 2251 of the fixed module 2250 that meshes with the second gear 2224b, and the motor housing 2210 can rotate relative to the driven gear 2251.

[0320] Furthermore, the second drive unit 2240 may include a second motor 2241, a second gear module 2242, and a shaft 2243.

[0321] The second gear module 2242 may include a second worm gear 2245 and a second reduction gear 2246.

[0322] The second worm gear 2245 can be coupled to the rotating shaft of the second motor 2241. The second worm gear 2245 can transmit rotational force to the second reduction gear 2246.

[0323] The second reduction gear 2246 can mesh with the second worm gear 2245, and can have a rotating shaft arranged in a direction different from the rotating shaft of the second worm gear 2245. The second reduction gear 2246 can provide a set gear ratio and is constructed using multiple gears that rotate simultaneously.

[0324] Furthermore, the second drive unit 2240 may include a third reduction gear 2247 that meshes with the second reduction gear 2246. In this case, the second reduction gear 2246 and the third reduction gear 2247 can provide different gear ratios to each other. The third reduction gear 2247 can transmit the final output to the third worm gear 2248, thereby causing the tilting rotation unit 2230 to tilt and rotate.

[0325] Furthermore, the fixing module 2250 can elastically support the motor housing 2210 on the fixing part 17.

[0326] The fixed module 2250 may include a driven gear 2251, a clamping plate 2252, a clamp 2253, an elastic component 2254, and a secondary gear 2255.

[0327] Driven gear 2251 can be fastened to motor housing 2210 (see reference) Figure 29 The driven gear 2251 is engaged with and fixed to the fixed part 17, but does not rotate on the fixed part 17. However, 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, thereby enabling folding rotation. That is, the driven gear 2251 can be fixed to the fixed part 17, and the first reduction gear 2224 can rotate with the driven gear 2251.

[0328] Furthermore, the clamp 2252 can be fixed to the front end of the fixing part 17 by the clamp 2253. The clamp 2252 may be provided with a step 2252a surrounding the clamp 2253 to prevent the clamp 2253 from detaching after being engaged with the fixing part 17.

[0329] The clamp 2253 can be engaged along the first fastening groove 17a formed at the front end of the fixing part 17. At this time, the clamp 2253 can form a second fastening groove 17b at the front end of the fixing part 17 where the first fastening groove 17a is not formed. The fixing protrusion 2253a protruding from the central region of the clamp 2253 can be inserted into the second fastening groove 17b. Therefore, as the fixing protrusion 2253a is inserted into the second fastening groove 17b, the clamp 2253 can prevent rotation of the front end of the fixing part 17 about the first rotation axis RA1.

[0330] Furthermore, the elastic member 2254 can provide elastic support between the driven gear 2251 and the clamping plate 2252. That is, the elastic member 2254 can provide elastic restoring force, so that the secondary gear 2255 applies pressure to the driven gear 2251 relative to the clamping plate 2252 fixed in position by the clamp 2253.

[0331] Furthermore, the secondary gear 2255 can be arranged to surround the outer side of the elastic member 2254 and can be placed on the driven gear 2251. Gear teeth can be formed on the outer peripheral surface of the secondary gear 2255 to mesh with a part of the control module 2270, which will be described later. The folded rotation state of the motor housing 2210 relative to the secondary gear 2255 can be transmitted to the control module 2270.

[0332] Furthermore, the control module 2270 may include a substrate 2271, a first potentiometer 2272 for sensing the rotation of the first drive unit 2220, and a second potentiometer 2273 for sensing the rotation of the second drive unit 2240.

[0333] The first potentiometer 2272 and the second potentiometer 2273 can be respectively disposed on the substrate 2271. Each potentiometer 2272 and 2273 can be implemented by a variable resistor that converts linear or rotational displacement into a change in resistance. Such potentiometers 2272 and 2273 can be configured as contact type or non-contact type. In this embodiment, a contact type configuration is described as an example. The contact type potentiometer has the structure of a brush moving resistor and can measure displacement according to the rotation angle or the number of rotations.

[0334] The first potentiometer 2272 may be configured with a first gear 2274 arranged rotatably on the substrate 2271, and the first gear 2274 may be arranged to mesh with the gear tooth profile 2256 of the secondary gear 2255. Therefore, the folding rotation angle of the motor housing 2210 can be calculated based on the rotation angle of the first gear 2274 relative to the gear tooth profile 2256 of the secondary gear 2255.

[0335] The second potentiometer 2273 may be equipped with a second gear 2275 arranged rotatably on the substrate 2271, and the second gear 2275 may be arranged to mesh with the gear teeth disposed on the inclined worm gear 2249. Therefore, the second gear 2275 can be positioned relative to the inclined worm gear 2249 with the first shaft 2243 as the center (see reference). Figure 34 The tilt rotation angle of the tilting rotating part 2230 is calculated by the rotation angle of the rotation of the rotating part.

[0336] The tilting worm gear 2249 can rotate within a limited angle range set corresponding to the tilting rotation range of the tilting rotating part 2230.

[0337] Furthermore, the motor mounting unit 2280 may include a first mounting unit 2281, a second mounting unit 2282, and a third mounting unit 2283.

[0338] The first mounting portion 2281 may be a region on one side of the motor mounting portion 2280 where the first motor 2221 is mounted, the second mounting portion 2282 may be a region on the other side of the motor mounting portion 2280 where the second motor 2241 is mounted, and the third mounting portion 2283 may be a region arranged between the first mounting portion 2281 and the second mounting portion 2282 for mounting the substrate 2271.

[0339] In the motor mounting section 2280, the first mounting section 2281 and the second mounting section 2282 can be formed to correspond to the capacities of the first motor 2221 and the second motor 2241, respectively, and can be formed to have different sizes. In this embodiment, an example is shown where the first mounting section 2281 is formed to be larger than the second mounting section 2282.

[0340] The third mounting portion 2283 can be configured as a slot to facilitate the assembly or separation of the substrate 2271. Therefore, since the substrate 2271 can be slidably inserted into or separated from the third mounting portion 2283, improved assemblability of the substrate 2271 is expected. The third mounting portion 2283 can provide a structure that connects the first mounting portion 2281 and the second mounting portion 2282 to each other.

[0341] The motor mounting part 2280 can be disposed on the motor housing 2210 after the first motor 2221 and the second motor 2241 are respectively assembled into the first mounting part 2281 and the second mounting part 2282 (see reference). Figure 29 Inside the lower housing 2211, along the direction in which the motor mounting section 2280 is attached to the lower housing 2211, the rotation axes of the first motor 2221 and the second motor 2241 can be arranged parallel to each other. For example, the rotation axes of the first motor 2221 and the second motor 2241 can be arranged parallel to the folding rotation axis RA1 of the motor housing 2210. Of course, the rotation axes of the first motor 2221 and the second motor 2241 can also be arranged at an angle to form a predetermined angle with the folding rotation axis RA1. In this way, since the motor mounting section 2280 sets the rotation axes of the first motor 2221 and the second motor 2241 in a direction that is approximately perpendicular to the bottom surface of the lower housing 2211, it has the advantage of significantly reducing the installation space compared to a structure in which the rotation axes of the motors are set horizontally to the bottom surface.

[0342] At least a portion of the lower end portion 2281a of the first mounting portion 2281 and the lower end portion 2282a of the second mounting portion 2282 can be inserted into and fixed to the third mounting portion 2218c of the lower housing 2211. When the motor mounting portion 2280 is inserted into and mounted on the third mounting portion 2218c, the first worm gear 2223 coupled to the rotating shaft of the first motor 2221 and the 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 the third reduction gear 2247, respectively. Of course, in the lower housing 2211, a fourth mounting portion 2218d for mounting the second reduction gear 2246 can be disposed between the second worm gear 2245 and the third reduction gear 2247.

[0343] Furthermore, when an external force is applied to the mirror housing 110 while the first motor 2221 is stopped, the driven gear 2251 can rotate relative to the secondary gear 2255 on the fixed part 17 with the first rotation axis RA1 as the center. This provides a structure that can be manually rotated to prevent damage between the first drive part 2220 and the driven gear 2251 when the mirror housing 110 is forced to rotate by an external force.

[0344] A recess 2251a may be formed on one side of the driven gear 2251 and the secondary gear 2255, and a third protrusion 2255a corresponding to the recess 2251a may be disposed on the other side. In this embodiment, an example is given where a recess 2251a is formed on the upper part of the driven gear 2251 and a third protrusion 2255a is disposed on the lower part of the secondary gear 2255. The recess 2251a and the third protrusion 2255a may be configured to contact each other at an inclined surface along the folding rotation direction. Therefore, when an external force exceeding a certain range is applied, the third protrusion 2255a may be discharged outward from the recess 2251a along the inclined surface. Multiple recesses 2251a and third protrusions 2255a may be arranged on the driven gear 2251 and the secondary gear 2255 at a set angle range, respectively.

[0345] Because the elastic member 2254 of the fixing module 2250 presses the secondary gear 2255 towards the driven gear 2251, the recess 2251a and the third protrusion 2255a can remain engaged with each other when the folding rotation is electrically formed by the drive device 2000. Here, if the mirror housing 110 is folded and rotated by external force when the first motor 2221 is stopped, the first drive unit 2220 and the driven gear 2251 fold and rotate on the fixing unit 17 in an engaged state. At this time, the engagement between the recess 2251a and the third protrusion 2255a is released, and the driven gear 2251 and the secondary gear 2255 can be separated from each other. Since multiple recesses 2251a and third protrusions 2255a are arranged along the folding rotation direction, a third protrusion 2255a discharged from one recess 2251a can be manually rotated until it is inserted into an adjacent recess.

[0346] Figure 40 It is shown Figure 29 The diagram shows a perspective view of another embodiment of the drive unit for a vehicle rearview mirror and the driven gear. Figure 41 It shows the cutting Figure 40 A reference diagram showing the state of the lower housing and a portion of the driven gear of the drive unit for a vehicle rearview mirror.

[0347] Reference Figure 40 and Figure 41The lower housing 2211 may include a stop 2211b protruding along the periphery of the cylindrical portion 2213 on the inner bottom surface 2211a of the lower housing 2211. Multiple stopes 2211b may be arranged facing each other at the center of the cylindrical portion 2213. In the stopes 2211b, a pair of unit stopes may be arranged in multiple regions. In this case, each stop 2211b may be arranged at the same distance from the center of the cylindrical portion 2213 in the radial direction. Furthermore, the spacing between adjacent unit stopes may all be the same. Of course, the stop 2211b and the unit stopes may also be constituted as a single body.

[0348] The stop 2211b can be formed in a generally hexahedral shape. For example, the stop 2211b can limit the range of relative rotation with respect to the driven gear 2251.

[0349] Furthermore, the driven gear 2251 may have a stop groove 2251b formed along the circumferential direction on its lower surface facing the bottom surface 2211a of the lower housing 2211.

[0350] The stop groove 2251b can be formed in multiple ways corresponding to the number of unit stop members. Of course, the individual stop grooves 2251b can be arranged at the same intervals or angles.

[0351] The lower housing 2211 can be electrically folded and rotated from a first position PO1 where one stop 2211b is disturbed by one side of the stop groove 2251b to a second position PO2 where the other stop is disturbed by the other side of the stop groove. Here, the range of folding rotation from the first position PO1 to the second position PO2 can correspond to the range of relative rotation between the lower housing 2211 and the driven gear 2251.

[0352] For example, if the lower housing 2211 rotates relative to the driven gear 2251 in one direction and a larger external force is applied in one direction while the stop 2211b and the stop groove 2251b are disturbed, such as Figure 20 As shown, driven gear 2251 and secondary gear 2255 (refer to...) Figure 39 The mirrors can be manually rotated while remaining spaced apart from each other. Thus, the structure of the embodiment that restrictively forms electric rotation can be partially applied in regions where the folding or unfolding function of vehicle rearview mirrors is not actively used.

[0353] Therefore, the drive device for a vehicle rearview mirror according to an embodiment of the present invention has the following effects: by mounting a first motor for folding, a second motor for tilting, and a base plate in a motor mounting part, assemblability can be improved while reducing the mounting space; the encapsulation of the drive device can ensure freedom for improving mirror design; the flow of the third turbine can be prevented between the tilting rotation part and the lower housing; and manual folding and rotation can be temporarily performed when an external force is applied to the mirror housing, thereby preventing damage to the first drive part and the fixing module.

[0354] Figure 42 It is shown Figure 28 The diagram shows a cross-sectional perspective view of the drive mechanism for a vehicle rearview mirror. Figure 43 It is shown Figure 42 The diagram shows a cross-sectional view of the drive mechanism for a vehicle rearview mirror along section C-C'. Figure 44 It is shown Figure 42 The diagram shows a reference figure of the first potentiometer of the drive mechanism for a vehicle rearview mirror. Figure 45 It is shown Figure 44 A reference diagram showing the process of the first potentiometer of the drive mechanism for a vehicle rearview mirror sensing its initial position.

[0355] Reference Figures 42 to 45 According to an embodiment of the present invention, the control module of the drive device of the vehicle rearview mirror can set the initial position of the folding rotation or the tilting rotation by sensing the folding rotation of the motor housing or sensing the tilting rotation of the tilting rotating part, respectively.

[0356] As described above, the control module 2270 may include a substrate 2271 (see reference 2271). Figure 38 The potentiometers 2272 and 2273 are used to sense the rotation of the first drive unit 2220 and the second drive unit 2240, respectively. The functions and operations of each potentiometer are the same as described above, so repeated explanations are omitted. The detailed structure of each potentiometer will be described below.

[0357] The first potentiometer 2272 and the second potentiometer 2273 can be respectively disposed on the substrate 2271, and the substrate 2271 can be detachably attached to the third mounting portion 2283 of the motor mounting portion.

[0358] The first potentiometer 2272 may include a first gear 2274 and a first position setting unit 2276.

[0359] When the motor housing 2210 (refer to) Figure 30When rotating around the folding rotation axis RA1, the first gear 2274 can mesh with the gear teeth 2256 of the secondary gear 2255 and rotate relative to (or revolve around) the periphery of the secondary gear 2255. A first position setting part 2276 can be installed on the inner side of the first gear 2274. A first serrated pattern 2274a in the form of an inner gear can be formed in the area on the inner side of the first gear 2274 facing the outer peripheral surface of the first position setting part 2276.

[0360] Furthermore, the first position setting unit 2276 can be arranged on the first gear 2274 with the same rotation axis as the rotation axis RA3 of the first gear 2274 as its center. That is, the first position setting unit 2276 can be arranged to be rotatable relative to the first gear 2274.

[0361] The first position setting part 2276 may include a first rotating body 2276a, a first contact part 2276b, a first leg part 2276c, and a first contact piece 2276d.

[0362] The first rotating body 2276a can be arranged to rotate around a rotation axis that is the same as the rotation axis RA3 of the first gear 2274. At least a portion of the first rotating body 2276a can be housed inside the first gear 2274. The outer contour region of the first rotating body 2276a can be arranged so that it does not contact the first gear 2274 in most areas. The first rotating body 2276a is formed in the shape of a generally circular plate, and a first contact portion 2276b is arranged adjacent to the rotation axis RA3.

[0363] Furthermore, the first contact portion 2276b can protrude further upward from the central region of the upper surface of the first rotating body 2276a. The first contact portion 2276b can be arranged to contact the first stop 2284, which will be described later.

[0364] Furthermore, the first leg 2276c can be arranged on both sides of a section cut along the circumferential direction of the first rotating body 2276a. For example, the first leg 2276c can be formed as a structure arranged on both sides of the sectioned portion in a partially cut ring structure. Therefore, a pair of first legs 2276c can be arranged on both sides with the section as the center, and can be arranged to elastically bend from the outer peripheral surface of the first rotating body 2276a.

[0365] Furthermore, the first contact piece 2276d can be disposed at each front end of the first leg 2276c. The first contact piece 2276d can be arranged to protrude further from the outer peripheral surface of the first rotating body 2276a, and can be arranged to contact the first serrated pattern 2274a of the first gear 2274. Therefore, when the first rotating body 2276a rotates relative to the first gear 2274, the first contact piece 2276d can elastically contact the first serrated pattern 2274a. If the relative rotation stops, the first rotating body 2276a can be fixed to maintain its rotation relative to the first gear 2274.

[0366] Furthermore, the motor mounting portion 2280 may include a first stop 2284. The first stop 2284 may be arranged on the motor mounting portion 2280 on the third mounting portion 2283 (see reference). Figure 35 The inside of ).

[0367] The first stop 2284 can be arranged within the rotation radius of the first contact portion 2276b, and can restrict the relative rotation of the first rotating body 2276a with respect to the first gear 2274 during the rotation of the first contact portion 2276b. Figure 45 In this design, one end face of the first stop 2284 is formed into a generally triangular shape and may include a first contact surface 2284a and a second contact surface 2284b. When the first rotating body 2276a rotates in one direction, the first contact surface 2284a contacts one side of the first contact portion 2276b; when the first rotating body 2276a rotates in the other direction, the second contact surface 2284b contacts the other side of the first contact portion 2276b. At this time, the interior angle between the first contact surface 2284a and the second contact surface 2284b in the first stop 2284 can be formed as an acute angle. That is, the first contact portion 2276b can rotate within a range excluding the size of the interior angle of the first stop 2284. Of course, the interior angle between the first contact surface 2284a and the second contact surface 2284b in the first stop 2284 can be set to a right angle or an obtuse angle greater than an acute angle.

[0368] Furthermore, the secondary gear 2255, which meshes with the first gear 2274, may have a chamfer 2255b. The chamfer 2255b may be formed such that the width of the gear narrows at the front end of the gear tooth profile of the secondary gear 2255 that initially engages with the first gear 2274. Therefore, when the first gear 2274 engages with the secondary gear 2255, meshing can be more easily achieved along the chamfer 2255b of the gear tooth profile.

[0369] exist Figure 44In this configuration, the first contact portion 2276b is arranged toward a virtual first point P1 formed on the first gear 2274. That is, a virtual straight line L1 connecting the center of rotation of the first gear 2274 to the center of the first contact portion 2276b along its length is arranged to intersect with the first point P1. As described above, it is assumed that the exact position is that the center of the first contact portion 2276b and the first point P1 are arranged side-by-side on the virtual straight line L1.

[0370] and Figure 44 The states are different; during the assembly of the first potentiometer 2272, in such cases... Figure 45 As shown, the first gear 2274 and the first position setting unit 2276 can be arranged in a position that is out of the accurate position (or does not intersect with the first point P1). In this case, after the assembly of the first potentiometer 2272 is completed, a position correction can be formed to place them in the accurate position.

[0371] To correct the position, such as Figure 45 As shown, the first position setting unit 2276 needs to rotate relative to the first gear 2274. For example, if the first gear 2274 is rotated in one direction D1, the first contact part 2276b contacts the first contact surface 2284a of the first stop member 2284. At this time, the first position setting unit 2276 is restricted from rotating by the first stop member 2284, while the first gear 2274 can continue to rotate. Therefore, only when the first gear 2274 rotates relative to the fixed first rotating body 2276a, if the rotation of the first gear 2274 is stopped at the position where the first contact part 2276b intersects with the first point P1, position correction to the accurate position can be completed.

[0372] exist Figure 45 In the example, the first gear 2274 is rotated in one direction D1 (or clockwise) to form a position correction to an accurate position. Conversely, the first gear 2274 can also be rotated in another direction (or counterclockwise) to form a position correction.

[0373] Figure 46 It is shown Figure 41 The diagram shown is a reference image of the second potentiometer and second stop of the vehicle rearview mirror drive unit before assembly. Figure 47 It is shown Figure 46 A reference diagram showing the process of the second potentiometer of the drive mechanism for a vehicle rearview mirror sensing the initial position.

[0374] Reference Figure 46 and Figure 47 The second potentiometer 2273 may include a second gear 2275 and a second position setting unit 2277.

[0375] When the tilting rotating part 2230 (refer to) Figure 42 ) relative to the lower shell 2211 (refer to Figure 41 When rotating around the inclined rotation axis RA2, the second gear 2275 can mesh and rotate with the inclined worm gear 2249. A second position setting part 2277 can be installed on the inner side of the second gear 2275. A second sawtooth pattern 2275a in the form of an internal gear is formed in the area on the inner side of the second gear 2275 facing the outer peripheral surface of the second position setting part 2277.

[0376] Furthermore, the second position setting unit 2277 can be arranged on the second gear 2275 with the same rotation axis as the rotation axis RA4 of the second gear 2275. That is, the second position setting unit 2277 can be arranged to be rotatable relative to the second gear 2275. The rotation axis RA3 of the first gear 2274 and the rotation axis RA4 of the second gear 2275 can be arranged in directions orthogonal to each other.

[0377] The second position setting unit 2277 may include a second rotating body 2277a, a second contact part 2277b, a second leg part 2277c, and a second contact piece 2277d.

[0378] Since the structure of the second position setting unit 2277 is the same as that of the first position setting unit 2276, repeated descriptions are omitted.

[0379] Furthermore, the motor mounting section 2280 may include a second stop 2285. The second stop 2285 may be disposed on the motor mounting section 2280 and mounted on the third mounting section 2283 (see reference). Figure 35 The inside of ).

[0380] The second stop 2285 may include a protruding part 2285a and a guide part 2285b.

[0381] The protruding member 2285a protrudes toward the second contact portion 2277b along the rotation axis of the second rotating body 2277a, thereby guiding the operating position of the second contact piece 2277d. That is, the protruding member 2285a can provide the function of smoothly inserting the second contact portion 2277b into the guiding member 2285b.

[0382] The protruding part 2285a may include a tip 2285c, a first guide part 2285d, and a second guide part 2285e.

[0383] The tip 2285c protrudes towards the rotation center of the second rotating body 2277a, thereby allowing the entry direction of the second rotating body 2277a to be set when it first contacts the protruding member 2285a. That is, the second rotating body 2277a is guided to rotate and move towards either the first guiding part 2285d or the second guiding part 2285e while simultaneously contacting the tip 2285c.

[0384] Furthermore, with the central axis of the second rotating body 2277a as a reference, when the second rotating body 2277a rotates in one direction, the first guiding portion 2285d can guide from the tip portion 2285c towards the guiding member 2285b; when the second rotating body 2277a rotates in another direction, the second guiding portion 2285e can guide from the tip portion 2285c towards the guiding member 2285b. The first guiding portion 2285d and the second guiding portion 2285e can be formed such that their area or width increases from the front end center of the tip portion 2285c along the x-axis and z-axis directions. The first guiding portion 2285d and the second guiding portion 2285e can be formed as inclined surfaces or curved surfaces.

[0385] Furthermore, while the guide member 2285b assembles the second contact portion 2277b via the protruding member 2285a, it can form a second reference range that serves as the rotation radius of the second contact portion 2277b. The guide member 2285b can extend downwards and to both sides in a "∧" shape to the range in which the second contact portion 2277b rotates around the rotation axis RA4 of the second gear 2275.

[0386] Therefore, when assembling the second contact portion 2277b and the second stop member 2285, no additional position adjustment is required, and they can be assembled at any position of the second contact portion 2277b while rotating toward the guide member 2285b.

[0387] Figure 48 It is shown Figure 1 The image shown is a reference diagram of a vehicle's rearview mirror.

[0388] Reference Figure 48 (a) shows the settings for the rearview mirror assembly of a vehicle with the steering wheel on the left, including vehicles in South Korea, and (b) shows the settings for the rearview mirror assembly of a vehicle with the steering wheel on the right, such as vehicles in Japan or the United Kingdom.

[0389] exist Figure 48 In (a), since the driver is positioned on the left side relative to the vehicle's direction of travel, the angle of the right-side rearview mirror 100R can be set to rotate toward the driver.

[0390] Furthermore, in Figure 48In (b), since the driver is positioned on the right side relative to the vehicle's direction of travel, the angle of the left-side rearview mirror 100L can be set to rotate toward the driver.

[0391] Of course, the settings of this rearview mirror assembly can be automatically applied according to the power on / off state or the vehicle driving mode (P, R, N, D), and can also be automatically set to the stored values ​​set by the driver.

[0392] Therefore, the drive device for a vehicle rearview mirror according to an embodiment of the present invention has the following effects: the accurate position of the first potentiometer or the second potentiometer can be corrected during the assembly of the control module, the assemblability of the control module can be increased, and it can also be easily applied to stop structures of various shapes and rotation ranges.

[0393] Figure 49 This is an exploded perspective view showing the drive mechanism of a vehicle rearview mirror according to a fourth embodiment of the present invention. Figure 50 It is shown Figure 49 The diagram shows a longitudinal cross-sectional view of the drive mechanism for a vehicle's rearview mirror. Figure 51 It is shown Figure 49 The reference diagram shows the combined state of the lower housing of the drive unit for a vehicle rearview mirror and the tilting rotating part on the second support. Figure 52 It shows the removal Figure 49 The diagram shows the state of the upper housing of the drive unit for a vehicle rearview mirror. Figure 53 It is to decompose and show Figure 52 An exploded perspective view of the first and second drive units of the vehicle rearview mirror drive mechanism shown. Figure 54 and Figure 55 It is shown Figure 53 The diagram shown is an exploded perspective view of the clutch section of the drive mechanism for a vehicle rearview mirror. Figure 56 Shown from the front Figure 54 The diagram shows a front view of the clutch portion of the drive mechanism for a vehicle rearview mirror. In the following text, the same reference numerals as those described above indicate the same configuration. Furthermore, repeated descriptions of the same configurations are omitted.

[0394] Reference Figures 49 to 56 Inside the lower housing 2211, there may be a fourth mounting section 2218e for housing the clutch section 2290 (described later), and a second exposure hole 2218f that extends into the lower housing 2211 and is disposed on the tilting rotating section 2230.

[0395] The second potentiometer 2273 may be configured with a second gear 2275 rotatable on the substrate 2271, and the second gear 2275 may be configured to mesh with a fifth gear portion 2249a disposed on the tilting worm gear 2249'. Therefore, with the shaft 2243 as the center, the tilting rotation angle of the tilting rotation portion 2230 can be calculated based on the rotation angle of the second gear 2275 relative to the tilting worm gear 2249'.

[0396] Furthermore, the tilting rotating part 2230 may have a mounting groove 2236' on the bottom surface 2231 corresponding to the fourth mounting part 2218e. Also, the tilting rotating part 2230 may have a mounting hole 2236a adjacent to the mounting groove 2236' and for engaging with the tilting worm gear 2249'.

[0397] The clutch section 2290 may include a third worm gear 2291, a clutch gear 2292, a clutch spring 2293, and a second support plate 2294.

[0398] This clutch 2290 can transmit the rotational force of the second drive unit 2240 to the tilting rotation unit 2230 within the lower housing 2211, centered on the tilting rotation shaft RA2, and can prevent the rotational force from being transmitted in the reverse direction from the tilting rotation unit 2230 to the second drive unit 2240. This prevents more than one power transmission configuration arranged between the second drive unit 2240 and the tilting rotation unit 2230 from being damaged during the transmission of external force.

[0399] The third worm gear 2291 includes a rotating body 2291a and a third gear part 2291b.

[0400] The rotating body 2291a can be arranged to surround the shaft 2243 and can be arranged to rotate around the shaft 2243. The rotating body 2291a is generally formed into a hollow cylindrical shape, and a third gear part 2291b can be arranged at one end.

[0401] The third gear section 2291b can protrude outward from one end of the rotating body 2291a and can be arranged to mesh with the third reduction gear 2247 of the second drive section 2240. That is, the rotational force based on the tilting rotation transmitted to the third reduction gear 2247 can be transmitted to the clutch gear 2292 through the third worm gear 2291.

[0402] The third worm gear 2291 may have an insertion groove 2291c formed at one end adjacent to the rotating body 2291a and the third gear portion 2291b. The insertion groove 2291c may have a predetermined annular groove formed inside the third gear portion 2291b, corresponding to the outer peripheral surface of the rotating body 2291a. A portion of the clutch gear 2292 may be inserted into the insertion groove 2291c.

[0403] Furthermore, the clutch gear 2292 may include a fourth gear portion 2292a, an insertion body 2292b, and a protruding piece 2292c.

[0404] The fourth gear 2292a can be engaged in a manner that surrounds the rotating body 2291a. The second gear 2275 can mesh with the inclined worm gear 2249', which will be described later. Therefore, the rotational force based on the inclined rotation transmitted to the third worm gear 2291 can be transmitted to the inclined worm gear 2249' via the clutch gear 2292. Here, the inclined worm gear 2249' can be engaged with the inclined rotating part 2230, and the rotational force transmitted to the inclined worm gear 2249' can be transmitted as the inclined rotational force of the inclined rotating part 2230.

[0405] Furthermore, the insertion body 2292b can protrude integrally from one side of the fourth gear part 2292a, and at least a portion of it can be inserted into the insertion slot 2291c together with the protruding piece 2292c.

[0406] Furthermore, the protruding piece 2292c can protrude from the interior of the fourth gear portion 2292a and the insertion body 2292b along the inclined rotation axis RA2. For example, the protruding piece 2292c can provide a keyed engagement function, such as securing the pulley to the shaft. The protruding piece 2292c can be arranged to contact or interfere with the clutch spring 2293, which will be described later.

[0407] Furthermore, the clutch spring 2293 can be formed into a hollow cylindrical shape, and can have an opening 2293a that is open on one side along the inclined rotation axis RA2. Therefore, a cross-section of the clutch spring 2293 can be formed into a roughly "C" shape. The clutch spring 2293 can be engaged and tightly attached to the rotating body 2291a in a manner that surrounds the outer peripheral surface of the rotating body 2291a. That is, the clutch spring 2293 can be tightly engaged to the rotating body 2291a by elastic restoring force. At this time, when the clutch spring 2293 is tightly attached to the rotating body 2291a and generates a rotational force with a force greater than the elastic restoring force, relative rotation can occur while sliding on the rotating body.

[0408] The clutch spring 2293 can be inserted into the clutch gear 2292 while engaged with the rotating body 2291a. At this time, the opening 2293a can be engaged in a manner corresponding to the protruding piece 2292c.

[0409] The clutch unit 2290 can be arranged to rotate around a shaft 2243 arranged along the inclined rotation axis RA2.

[0410] Furthermore, the second support plate 2294 can make the inner circumferential surface of the fourth gear portion 2292a form a concentric circle with the shaft 2243, thereby supporting the other side of the rotating body 2291a to prevent eccentricity. A protruding piece 2292c can be disposed inside the fourth gear portion 2292a, and correspondingly, the second support plate 2294 can form a second opening 2294a, which, together with the clutch spring 2293, provides support to prevent the rotating body 2291a from being eccentric inside the clutch gear 2292. Of course, the second support plate 2294 can also be integrally formed with the other end of the clutch spring 2293. In the clutch gear 2292, the other end of the fourth gear portion 2292a can be inserted in such a way that the shaft 2243 passes through, and a portion can be shielded to prevent the second support plate 2294 from passing through.

[0411] Furthermore, the tilting worm gear 2249' may include a fifth gear portion 2249a disposed on the upper outer side and a sixth gear portion 2249b disposed on the lower inner side. The tilting worm gear 2249' may be detachably coupled to the tilting rotating portion 2230. The tilting worm gear 2249' may be arranged to penetrate the lower part of the lower housing 2211 and be exposed inside the lower housing 2211.

[0412] The fifth gear section 2249a can be arranged to mesh with the second gear 2275 connected to the second potentiometer 2273, and can provide tilt rotation information to the second potentiometer 2273.

[0413] Furthermore, the sixth gear section 2249b can be arranged to mesh with the fourth gear section 2292a of the clutch gear 2292.

[0414] Furthermore, the inclined worm gear 2249' may have a rotating shaft hole 2249c that is connected to the lower part of the sixth gear portion 2249b in such a way that the shaft 2243 passes through.

[0415] Furthermore, the tilting worm gear 2249' can be detachably attached to the tilting rotating part 2230. In this case, fastening hooks 2249d that are inserted into the tilting rotating part 2230 can be provided at both ends of the tilting worm gear 2249'.

[0416] Therefore, if the third worm gear 2291 generates a rotational force, the clutch spring 2293 rotates together. Because the clutch spring 2293 is disturbed by the protruding plate 2292c, the clutch gear 2292 can rotate together. If the clutch gear 2292 rotates, the tilting worm gear 2249' can rotate while the tilting rotating part 2230 tilts and rotates. Conversely, when the tilting rotating part 2230 generates an external force, the tilting worm gear 2249' rotates together while the clutch gear 2292 rotates. Since the third worm gear 2291 is engaged with the second drive part 2240, the third worm gear 2291 cannot rotate, thus slippage may occur between the clutch gear 2292 and the third worm gear 2291. That is, while the clutch gear 2292 rotates, the clutch spring 2293 is disturbed by the protruding plate 2292c and rotates together with the clutch gear 2292, but the clutch gear 2292 and the rotating body 2291a can slide while rotating relative to each other. Therefore, the clutch section 2290 can prevent the second drive section 2240 and the tilting rotation section 2230 from being damaged by external forces.

[0417] Figure 57 and Figure 58 It is shown Figure 54 A reference diagram showing the operating state of the clutch section of the drive unit for a vehicle rearview mirror.

[0418] Reference Figure 57 and Figure 58 The rotating shaft hole 2249c of the inclined worm gear 2249' can be formed as an elongated hole. When the fourth gear part 2292a and the sixth gear part 2249b mesh and rotate relative to each other, the inclined worm gear 2249' can rotate and move along the elongated hole direction of the rotating shaft hole 2249c.

[0419] exist Figure 57 If the clutch part 2290 rotates, the fourth gear part 2292a and the sixth gear part 2249b can mesh to rotate the tilting worm gear 2249'. At this time, the shaft 2243 passes through the rotating shaft hole 2249c and is fixed in position on the lower housing 2211, but the tilting worm gear 2249' may undergo a predetermined horizontal movement.

[0420] Reference Figure 58 It can be confirmed that in Figure 57 In this state, the clutch unit 2290 rotates further, while the tilting worm gear 2249' moves further to the right around the shaft 2243. At this time, the clutch unit 2290 can rotate only around the shaft 2243.

[0421] The center of rotation of the tilting worm gear 2249' is not located on the shaft 2243, but can be arranged at a position separated from the shaft 2243 by the upper or lower part. Therefore, when the clutch gear 2292 is rotated, the tilting worm gear 2249' can move horizontally along with the rotation.

[0422] Therefore, the drive device for a vehicle rearview mirror according to an embodiment of the present invention has the following effects: the second drive unit can be prevented from being damaged by external force by arranging a clutch unit on the path that transmits the tilting rotational force of the second drive unit; if an external force of a set range or more is applied, the second drive unit can be manually rotated when it is stopped.

[0423] Figure 59 This is a perspective view showing the driving device of a vehicle rearview mirror inside a frameless mirror assembly for vehicles according to a fifth embodiment of the present invention. Figure 60 It is to separate and show Figure 59 An exploded perspective view of the drive mechanism for a vehicle rearview mirror.

[0424] Reference Figure 59 and Figure 60 The vehicle frameless mirror assembly may include the drive unit 3200 for the vehicle rearview mirror inside.

[0425] The drive unit 3200 includes a motor housing 3210 disposed inside the mirror housing 110, and a drive unit 3210 that participates in the mirror housing 110 (see reference 3210). Figure 6 The folding and rotating first drive unit 3220, tilting and rotating unit 3230, second drive unit 3240 participating in the tilting and rotating of tilting and rotating unit 3230, fixing module 3250 disposed on fixing unit 17, and control module 700 (see reference) Figure 62 ).

[0426] First, the motor housing 3210 may include a lower housing 3211 and an upper housing 3212.

[0427] The lower housing 3211 can be located inside the lower outer housing 111, and the upper housing 3212 can be attached to the upper part of the lower housing 3211 while forming the motor housing 3210. In this case, the motor housing 3210 can be located inside the mirror housing 110, but is not attached to the mirror housing 110, but is only attached to the fixing part. For example, the first drive unit 3220 can provide a folding drive for the mirror housing 110 by providing relative rotation of the motor housing 3210 relative to the fixing module 3250 with the first rotation axis RA1 formed in the fixing part 17 as the center, and the second drive unit 3240 can provide relative rotation to the tilting rotation unit 3230 with respect to the second rotation axis RA2 formed between the motor housing 3210 and the tilting rotation unit 3230 to provide a tilting drive for the mirror housing 110.

[0428] The lower housing 3211 may include a cylindrical portion 3213 and an inclined shaft fastening portion 3214.

[0429] The cylindrical portion 3213 can protrude downward from one side of the lower housing 3211 and can be configured in a cylindrical shape to surround the fixing portion 17 when the fixing portion 17 is inserted into the center.

[0430] Furthermore, a support member 3215 can be additionally fastened around the periphery of the cylindrical portion 3213. While the support member 3215 is fastened around the periphery of the cylindrical portion 3213, a portion of the tilting rotating portion 3230 is sandwiched between the lower housing 3211 and the support member 3215 to support one side of the tilting rotating portion 3230.

[0431] The support member 3215 may include a guide member 3216 that guides the direction of engagement with the lower housing 3211 to an accurate position. The guide member 3216 may be formed using one or more protrusions and groove structures facing the lower part of the lower housing 3211. In this embodiment, an example is shown where the guide member 3216 with groove structures arranged in a straight line is disposed on the upper surface of the support member. Of course, a protrusion 3213a structure of a corresponding shape may be formed on the outer peripheral surface of the cylindrical portion 3213 of the lower housing 3211. Therefore, the engagement direction of the support member 3215 with the lower housing 3211 can be set by the guide member 3216. Furthermore, the guide member 3216 and the protrusion 3213a may be disturbed along the folding rotation direction, causing the support member 3215 and the cylindrical portion 3213 to rotate together when the motor housing 3210 is folded and rotated.

[0432] Furthermore, the support member 3215 may include a pair of support ends 3217 protruding toward the bottom surface of the lower housing 3211. The support ends 3217 may be arranged spaced apart from each other along the axial direction of the second rotation axis RA2 with the cylindrical portion 3213 as the center, thereby rotatably supporting one side of the tilting rotating portion 3230, which will be described later.

[0433] The support member 3215 can be arranged to be rotatable from the fixing part 17 as the folding rotation occurs. At this time, a bushing 3218 can be additionally provided in the area where the support member 3215 and the fixing part 17 are in contact with each other.

[0434] Furthermore, the tilting shaft fastener 3214 can support the other side of the tilting rotating part 3230 from the other side of the lower housing 3211. The tilting shaft fastener 3214 can be fastened to the shaft 3243 disposed on the second rotating shaft RA2 of the lower housing 3211, and the tilting rotating part 3230 can be rotatably fastened to the shaft 3243 with the second rotating shaft RA2 as the center.

[0435] Furthermore, the tilting rotation unit 3230 can be configured to rotate relative to a second rotation axis RA2 (or tilting rotation axis) formed at the lower center of the motor housing 3210. Of course, the tilting rotation unit 3230 can be driven by the second drive unit 3240 to rotate from the motor housing 3210 in the tilting direction. In this case, the tilting rotation unit 3230 can rotate together with the mirror housing 110 and the reflective unit 120 around the second rotation axis RA2.

[0436] The tilting and rotating part 3230 may include a bottom surface 3231, a first support part 3232, a second support part 3233, and a side wall 3234.

[0437] The bottom surface 3231 can be arranged to face and be spaced apart from the bottom surface of the lower housing 3211. The bottom surface 3231 and the lower housing 3211 can be arranged to be spaced apart from each other for relative rotation according to their tilting rotation.

[0438] Furthermore, the first support portion 3232 and the second support portion 3233 can be arranged on the bottom surface 3231 separately from each other.

[0439] The first support part 3232 can support one side of the bottom surface with the second rotation axis RA2 as the center, and the second support part 3233 can support the other side of the bottom surface 3231 with the second rotation axis RA2 as the center.

[0440] The first support portion 3232 may include a pair of support plates 3235 spaced apart from each other along the second rotation axis RA2 with the cylindrical portion 3213 as the center. Each support plate 3235 may be arranged on each support end 3217 of the support member 3215 and may be arranged to be in surface contact with each other.

[0441] Furthermore, the sidewall 3234 can be arranged to face the two side surfaces of the lower housing 3211, and can be arranged to surround the lower housing 3211.

[0442] Therefore, the tilting rotating part 3230 can be arranged to tilt and rotate on the lower housing 3211 about the second rotation axis RA2.

[0443] Furthermore, the tilting and rotating part 3230 can be fastened to the mirror housing 110 together with the fixed frame 3260 (see reference). Figure 6Inside the mirror housing 110. Although the tilting rotating part 3230 is only fastened to the lower housing 3211, with the further configuration of the fixing frame 3260, the tilting rotating part 3230 can be firmly fastened to the upper housing 112 and the back plate 130 via the fixing frame 3260. Of course, the fixing frame 3260 can tilt and rotate together with the mirror housing 110 around the second rotation axis RA2, and can more firmly support the support structure that rotates the tilting rotating part 3230 inside the mirror housing 110.

[0444] Detailed descriptions of the fixed module 3250 and the control module 700 will be provided below.

[0445] Figure 61 It shows the removal Figure 59 The diagram shows the state of the upper housing of the drive unit for a vehicle rearview mirror. Figure 62 It is to decompose and show Figure 61 An exploded perspective view of the first and second drive units of the vehicle rearview mirror drive mechanism shown.

[0446] Reference Figure 61 and Figure 62 The first drive unit 3220 may include a first motor 3221 and a first gear module 3222, and can rotate according to the rotation of the first motor 3221 and the final output of the first gear module 3222.

[0447] The first gear module 3222 may include a first worm gear 3223 and a first reduction gear 3224.

[0448] The first worm gear 3223 can be coupled to the rotating shaft of the first motor 3221. The first worm gear 3223 can transmit rotational force to the first reduction gear 3224.

[0449] The first reduction gear 3224 can mesh with the first worm gear 3223, and can have a rotating shaft arranged in a direction different from the rotating shaft of the first worm gear 3223. The first reduction gear 3224 provides a set gear ratio and is composed of multiple first gears 3224a and second gears 3224b that rotate simultaneously.

[0450] Therefore, the final output of the first gear module 3222 can be transmitted to the first reduction gear 3224, and the first reduction gear 3224 can mesh with the driven gear 3251 of the fixed module 3250 that meshes with the second gear 3224b, and the motor housing can rotate relative to the driven gear 3251.

[0451] Furthermore, the second drive unit 3240 may include a second motor 3241, a second gear module 3242, and a shaft 3243.

[0452] The second gear module 3242 may include a second worm gear 3245 and a second reduction gear 3246.

[0453] The second worm gear 3245 can be coupled to the rotating shaft of the second motor 3241. The second worm gear 3245 can transmit rotational force to the second reduction gear 3246.

[0454] The second reduction gear 3246 can mesh with the second worm gear 3245, and can have a rotating shaft arranged in a direction different from the rotating shaft of the second worm gear 3245. The second reduction gear 3246 provides a set gear ratio and is constructed using multiple gears that rotate simultaneously.

[0455] Furthermore, the second drive unit 3240 may include a third reduction gear 3247 that meshes with the second reduction gear 3246. In this case, the second reduction gear 3246 and the third reduction gear 3247 can provide different gear ratios. The third reduction gear 3247 can transmit the final output to the shaft 3243 connected to the third worm gear 3248.

[0456] Furthermore, the fixing module 3250 can elastically support the motor housing 3210 on the fixing part.

[0457] The fixed module 3250 may include a driven gear 3251, a clamping plate 3252, a clamp 3253, an elastic member 3254, and a secondary gear 3255.

[0458] Driven gear 3251 can be fastened inside the motor housing 3210 so that the fixing part 17 passes through the interior. Although driven gear 3251 is engaged and fixed to the fixing part 17 without rotating, the rotational force transmitted from the first reduction gear 3224 to driven gear 3251 can cause the motor housing 3210 to rotate relative to driven gear 3251, thereby enabling folding rotation. That is, driven gear 3251 can be fixed to the fixing part 17, and the first reduction gear 3224 can rotate with driven gear 3251.

[0459] Furthermore, the clamp 3252 can be fixed by the clamp 3253 at the front end of the fixing part 17.

[0460] Furthermore, the elastic component 3254 can provide elastic support between the driven gear 3251 and the clamping plate 3252.

[0461] Furthermore, the secondary gear 3255 can be arranged to surround the outer side of the elastic member 3254 and can be placed on the driven gear 3251. Gear teeth can be formed on the outer peripheral surface of the secondary gear 3255 to mesh with a part of the control module 700, which will be described later, and the folded rotation state of the motor housing 3210 relative to the secondary gear 3255 can be transmitted to the control module 700.

[0462] Furthermore, the control module 700 may include a first potentiometer 710 for sensing the rotation of the first drive unit 3220, a second potentiometer 720 for sensing the rotation of the second drive unit 3240, and a substrate 730.

[0463] The first potentiometer 710 and the second potentiometer 720 can be respectively disposed on the substrate 730. Each potentiometer 710, 720 can be implemented by a variable resistor that converts linear displacement or rotational displacement into a change in resistance. Such potentiometers 710, 720 can be configured as contact type or non-contact type; in this embodiment, a contact type configuration is described as an example. The contact type potentiometer, as a brush moving resistor structure, can measure displacement based on the rotation angle or the number of rotations.

[0464] The first potentiometer 710 may be configured with a first gear 3274 arranged rotatably on the substrate 730, and the first gear 3274 may be arranged to mesh with the gear teeth of the secondary gear 3255. Therefore, the first potentiometer 710 can calculate the folding rotation angle of the motor housing 3210 based on the rotation angle of the first gear 3274 relative to the gear teeth 3256 of the secondary gear 3255.

[0465] The second potentiometer 720 may be equipped with a second gear 3275 arranged rotatably on the substrate 730, and the second gear 3275 may be arranged to mesh with the gear teeth disposed on the inclined worm gear 3249. Therefore, the second potentiometer 720 can calculate the tilt rotation angle of the inclined rotating part 3230 based on the rotation angle of the second gear 3275 about the shaft 3243 relative to the inclined worm gear 3249.

[0466] Shaft 3243 can be coupled in a manner that allows it to rotate simultaneously with the third worm gear 3248 and the inclined worm gear 3249. The third worm gear 3248 can mesh with the third reduction gear 3247 to transmit output to shaft 3243. The third worm gear 3248 and the inclined worm gear 3249 can be formed as a single unit.

[0467] The tilting worm gear 3249 can be arranged to rotate within a limited angle range as the shaft 3243 rotates.

[0468] The following describes the control device for a vehicle rearview mirror that controls the drive of a frameless mirror assembly.

[0469] Figure 63 This is a simplified block diagram illustrating a control device for a vehicle rearview mirror according to an embodiment of the present invention. Figure 64 It is a simplified representation. Figure 63 The diagram shown is a detailed block diagram of the control module of the vehicle rearview mirror control device. Figure 65It is shown Figure 3 The reference diagram shows the first and second rotation axes of the frameless mirror for the vehicle.

[0470] The frameless mirror assembly for vehicles may include a control device for the vehicle rearview mirror inside. The control device for the vehicle rearview mirror is equivalent to the control module 700 arranged inside the mirror housing 110 described above, and will be collectively referred to as the control module 700 below.

[0471] Reference Figures 63 to 65 According to an embodiment of the present invention, a control device for a vehicle rearview mirror may include a controller 740 and the control module 700 described above. Here, the controller 740 and the control module 700 may be disposed together in the motor housing 210 (see reference 2010). Figure 9 (The interior of)

[0472] First, the controller 740 can receive power from the smart junction box 701 located in the vehicle. The smart junction box 701 can distribute the power supplied from the vehicle's battery to the various parts of the vehicle that need it, and can send and receive information with the control module 700 or various sensors via CAN communication.

[0473] Furthermore, the controller 740 can receive user control signals from the door area unit (DAU) 702 via CAN or LIN communication.

[0474] Furthermore, the control module 700 may include a first potentiometer 710, a second potentiometer 720, and a substrate 730.

[0475] Since the first potentiometer 710 and the second potentiometer 720 are the same as described above, repeated descriptions are omitted.

[0476] Furthermore, the substrate 730 may include a sequence control unit 731, a speed control unit 732, and a memory unit 733.

[0477] In the sequence control unit 731 and the speed control unit 732, for example, the control logic for setting the sequence can be stored in the memory unit 733 or constructed using a PCB circuit.

[0478] The sequence control unit 731 can control the first drive unit 3220 (or the first motor 3221) or the second drive unit 3240 (or the second motor 3241) to drive them in a set order by determining the drive sequence of the first drive unit 3220 (or the first motor 3221) or the second drive unit 3240 (or the second motor 3241).

[0479] Furthermore, the speed control unit 732 can utilize PWM control logic to precisely control the rotation angle of the first drive unit 3220 centered on the first rotation axis RA1 or the motor housing 210 (see reference). Figure 11 Position adjustment.

[0480] The substrate can selectively supply power to at least one or more of the following: blind spot collision warning light (BCW) 703, frameless mirror heater 704, puddle light 705, and turn signal (not shown).

[0481] Furthermore, the speed control unit 732 can provide voltage to the first drive unit 3220 and the second drive unit 3240 according to external temperature control.

[0482] That is, if power is applied to the vehicle, the current temperature outside the vehicle can be detected by a temperature sensor (not shown) installed outside the vehicle, compared with a set reference temperature, and the voltage supplied to each drive unit 3220, 3240 can be adjusted accordingly.

[0483] For example, if the reference temperature is set to 25°C, and the ambient temperature around the vehicle exceeds the set range, the speed control unit 732 can provide high or low voltage depending on whether the ambient temperature is low or high. The memory unit 733 can store reference temperature and reference current value information in a lookup table. After comparing the reference temperature with the current temperature, the speed control unit 732 can control the voltage value to be variably provided to each drive unit 3220, 3240 based on the result.

[0484] In the following description, the sequential control or speed control of the first drive unit 3220 and the second drive unit 3240 by the control module 700 is explained according to different embodiments.

[0485] Figure 66 This is a reference diagram showing a frameless mirror switch located on the driver's side door of a vehicle. Figure 67 It shows through Figure 63 The control device for the vehicle rearview mirror shown is based on a curve of the rotation time difference of folding or slight tilting centered on a first rotation axis.

[0486] Reference Figure 66 and Figure 67 The diagram schematically shows a switch for controlling the frameless mirror (or exterior rearview mirror) on the driver's side door of the vehicle.

[0487] Switch 800 may include a micro-tilt switch 810, a folding switch 820, a mirror selector switch 830, etc.

[0488] Unlike ordinary rearview mirrors, frameless mirrors have a reflective section 120 (see reference). Figure 3 ) and mirror housing 110 (refer to Figure 3 They rotate together, so the reflector 120 and the mirror housing 110 can be folded or tilted and rotated simultaneously.

[0489] In this embodiment, the rotation of the frameless mirror can be controlled such that the speed at which the frameless mirror tilts slightly from a first position to a position between the first and second positions due to the operation of the micro-tilt switch is slower than the speed at which the frameless mirror rotates from the first position, which is a set unfolded position, to the second fully folded position due to the operation of the folding switch.

[0490] Here, slight tilt is indicated by the first rotation axis RA1 (refer to...). Figure 15 Rotation in the folding or unfolding direction centered on the first rotation axis RA1, because it rotates at a speed significantly slower than when fully folded to the second position or fully unfolded to the first position, is therefore described as a slight tilt. Of course, in the following text, to prevent folding and slight tilting centered on the first rotation axis RA1 or centered on the second rotation axis RA2 (see reference...), Figure 15 The tilted chaos rotating around the center will be recorded together as the rotation axis as the center of rotation.

[0491] Furthermore, the folding and slight tilting of the center of the first rotating axis RA1 are preferably set to default values, so that rotation can be performed independently of or sequentially and continuously with respect to the tilting of the center of the second rotating axis RA2. This is to prevent friction or operational instability that may occur when folding and tilting are performed simultaneously.

[0492] The speed control unit 732 mentioned above (refer to) Figure 64 Different speeds for full folding and micro-tilting allow users to perform fine adjustments to the frameless glasses more conveniently and stably during micro-tilting.

[0493] exist Figure 67 In this context, the voltage difference represents the speed of complete folding and slight tilting.

[0494] Figure 67 (a) shows the first graph of voltage and time based on ordinary full folding, and Figure 67 (b) shows a second curve G2 based on voltage and time with a slight tilt, such that the second curve G2 partially overlaps with the first curve G1.

[0495] That is, it can be confirmed that the voltage of the slightly tilted second curve G2 is relatively low compared to the first curve G1 based on complete folding, and it takes more time to reach the same position (or angle). This is because a first drive unit is needed to execute the first rotation axis RA1 (see reference). Figure 65 The center is completely folded and slightly tilted, thus having the advantage of being able to effectively distinguish speed differences when speed differences are inevitable.

[0496] Here, along with the speed difference based on full folding and slight tilting, the additional effects based on speed difference can also be highlighted during a series of full folding or full unfolding processes.

[0497] For example, speed control unit 732 (see reference) Figure 64 The frameless mirror can be controlled to gradually decrease its folding rotation speed as it rotates from a first position (set as the unfolded position) to a second fully folded position, ensuring a smooth folding motion before complete folding. This means that reducing the closing speed before the power window is fully closed reduces impact noise or vibration, providing a smooth window closure with a sophisticated feel. Similarly, the frameless mirror gradually decreases its rotation speed before full folding, eliminating impact noise or vibration with a smooth, still feel while providing a sophisticated operating experience. Of course, the speed control unit can also control the unfolding rotation speed, ensuring that it decreases not only during folding but also during unfolding, before reaching the first fully unfolded position.

[0498] Figure 68 This shows the frameless mirror through Figure 63 The diagram shows the vehicle's rearview mirror control device in either an unfolded or folded state. Figure 69 It is shown Figure 62 The reference diagram shows a stop that restricts rotation of a frameless mirror in the folding or unfolding direction.

[0499] Figure 68 (a) shows the tilted state of the frameless mirror in the unfolded state, forming the center of the second rotation axis RA2. Figure 68 (b) shows the frameless mirror fully folded.

[0500] Sequence control unit 731 (see reference) Figure 64 The control sequence of the first drive unit and the second drive unit can be set, or the corresponding settings can be stored in the memory unit.

[0501] For example, the sequence control unit 731 can restrict tilt rotation based on the second rotation axis RA2 after the frameless mirror is fully folded from the first position to the second position based on the first central axis. That is, the frameless mirror is preferably set to always maintain the same orientation and angle in the fully folded state. Of course, the angle in which the frameless mirror faces in the fully folded state can be adjusted within a set range according to the settings. Of course, the first position and the second position can also be customized, and if the settings are completed, the setting information can be stored in the memory unit 733 (see reference). Figure 64 ).

[0502] Furthermore, the sequence control unit 731 can control the frameless mirror so that it returns to its tilted rotation state before rotating from a tilted state to a fully folded second position based on the second rotation axis RA2. That is, the sequence control unit 731 can tilt or slightly tilt the frameless mirror in the unfolded state, but restrict the tilt or slight tilt in the folded state, or restrict the full folding state with an additional tilt in the fully unfolded state.

[0503] Furthermore, the memory unit 733 (see reference) Figure 64 The rotational position of the frameless mirror can be stored based on information provided by the first potentiometer 710 or the second potentiometer 720.

[0504] For example, the support member 3215 can be arranged to rotate around the fixing part 17 described above. In this case, rotation in the folding or unfolding direction based on the first rotation axis RA1 can be limited by a stop member disposed between the lower part of the support member 3215 and the fixing part 17. The stop member may include first steps 17c arranged at equal intervals on the outer peripheral surface of the fixing part 17 and second steps 3215a disposed on the lower part of the support member 3215 so as to be disturbed by the respective first steps 17c by rotation during folding or unfolding.

[0505] After the frameless mirror is rotated to its maximum in either the folding or unfolding direction to bring the first step 17c into contact with the second step 3215a on one side, and then rotated to its maximum in the other direction to bring the first step 17c into contact with the second step 3215a on the other side, scan information based on the rotation time of the frameless mirror or the voltage variation during rotation can be stored. Therefore, the memory unit 733 can store a first position, based on the scan information, which is a set unfolding position for the frameless mirror, and a second position, which is fully folded from the first position. Of course, the memory unit 733 can also store accurate position information of the tilt center of the frameless mirror at the first position, and can also store information on the individual tilt angle at the first position customized by the user.

[0506] Figure 70 This is a block diagram illustrating a control device for a vehicle rearview mirror according to another embodiment of the present invention.

[0507] Reference Figure 70 According to another embodiment of the present invention, the control device for a vehicle rearview mirror may include a controller 740' and a control module 700', and the controller may be disposed on the outside of the vehicle as a frameless mirror and receive power and control signals from the vehicle.

[0508] Furthermore, the control module 700' may include a first potentiometer 710, a second potentiometer 720, and a substrate 730, and the first potentiometer 710 and the second potentiometer 720 may provide the measured voltage to a controller installed in the vehicle.

[0509] At this time, the substrate 730 is controlled by the controller 740' or by control signals provided from a separate control device of the vehicle (e.g., ECU), and can also be applied to a so-called virtual substrate.

[0510] Therefore, the vehicle rearview mirror assembly and its control device according to an embodiment of the present invention have the following effects: they can provide optimized functions for frameless mirrors, and can simultaneously fold and tilt the mirror housing and mirror, thereby reducing the number of actuators; while independently performing folding rotation and tilting rotation, the speed of folding rotation and micro-tilting rotation can be controlled; and the appearance of a uniform folding state can be maintained while being customized according to folding and tilting.

[0511] The present invention has been illustrated above with specific embodiments to demonstrate its technical concept. However, the present invention is not limited to the same structure and function as described in the specific embodiments. Various modifications can be implemented without departing from the scope of the present invention. Therefore, such modifications should also be considered to fall within the scope of the present invention, and the scope of the present invention should be determined by the scope of the claims.
