Description

Technical Field

[0001] This utility model relates to a vehicle drive device, and more specifically, to a vehicle drive device for adjusting the gap between a mirror housing and a base mounted on a vehicle. Background Technology

[0002] The vehicle is 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 see what's behind and to the sides. The driver can use the field of vision ensured by the interior and exterior rearview mirrors to be aware of surrounding vehicles and pedestrians, and to execute actions such as reversing, overtaking, and changing lanes.

[0003] Recently, in order to reduce air resistance and the possibility of damage from external impacts while the vehicle is in motion, camera-mounted rearview mirrors, which include a camera, are being used instead of exterior rearview mirrors. Since the image of the vehicle's surroundings, captured by the camera-mounted rearview mirror, is displayed on a display device inside the vehicle, the driver can easily monitor the situation around the vehicle.

[0004] Additionally, when the vehicle is in motion, the exterior rearview mirrors or camera mirrors are deployed to allow the driver to be aware of the vehicle's surroundings. However, when the vehicle is parked or passing through narrow spaces, the exterior rearview mirrors or camera mirrors need to be folded towards the vehicle's side to prevent damage or 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.

[0007] Technical issues

[0008] The technical problem to be solved by this utility model is to provide a vehicle drive device for adjusting the gap between the mirror housing and the base of a vehicle.

[0009] The technical problems to be solved by this utility model are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned through the following description.

[0010] Technical solution

[0011] A vehicle drive device according to an embodiment of the present invention includes: a fixing part fixed to a mirror base of a vehicle; a drive part fixed to a mirror housing of the vehicle and generating a driving force to rotate the mirror housing about the fixing part; and a base elastic part disposed between the fixing part and the drive part, and generating an elastic force in the direction of pushing the drive part relative to the fixing part, wherein the position of the mirror housing can be converted to a first position unfolded relative to the mirror base or a second position folded relative to the mirror base, wherein when the position of the mirror housing is converted from the second position to the first position, the drive part moves the mirror housing closer to the mirror base at a predetermined reference interval, and when the position of the mirror housing is converted from the first position to the second position, the drive part separates the mirror housing from the mirror base at an interval greater than the reference interval.

[0012] The base elastic portion includes a wave spring provided in a ring shape.

[0013] The fixing part includes: a first cylinder; and a second cylinder having a smaller diameter than the first cylinder and protruding from the first cylinder, wherein the base elastic part passes through the second cylinder and is disposed on the first cylinder.

[0014] The first cylinder includes: an elastic part mounting surface for mounting the elastic part of the base; and a plurality of fixed guide protrusions that protrude in a ring shape along the edge of the elastic part mounting surface.

[0015] The driving part includes: a driving body, fixed to the mirror housing and rotatably coupled to the fixing part, wherein the driving body includes: an elastic part contact surface that contacts the elastic part of the base; and a driving guide protrusion that protrudes in a ring shape along the edge of the elastic part contact surface in a plurality of forms.

[0016] When the mirror housing is in the first position, each of the plurality of drive guide protrusions is inserted into a fixed guide groove formed between adjacent fixed guide protrusions among the plurality of fixed guide protrusions, and when the mirror housing is in the second position, each of the plurality of drive guide protrusions is released from the corresponding fixed guide groove.

[0017] During the transition of the mirror housing from the second position to the first position, the base elastic portion restricts the drive body from approaching the fixing portion, thereby preventing each of the plurality of drive guide protrusions from being inserted into the corresponding fixing guide groove.

[0018] The drive unit further includes a stop ring, which passes through the fixed part to prevent the drive unit from rotating relative to the fixed part along the rotation direction of the mirror housing and is movable in the direction of the rotation axis of the mirror housing. The stop ring includes a stop reference surface facing the drive body and a stop guide groove formed by an arc-shaped recess at the edge of the stop reference surface. The drive body includes a drive reference surface facing the stop ring and a stop guide protrusion protruding from the drive reference surface.

[0019] When the mirror housing is in the first position, the stop guide protrusion is spaced apart from the stop guide groove by a predetermined interval, and when the mirror housing is in the second position, the stop guide protrusion is inserted into the stop guide groove.

[0020] The stop guide groove includes a stop guide groove inclined surface that is inclined relative to the rotation axis of the mirror housing.

[0021] When the position of the mirror housing changes from the second position to the first position, the stop guide protrusion is guided by the inclined surface of the stop guide groove, and the drive body moves close to the fixing part, so that each of the plurality of drive guide protrusions is inserted into the corresponding fixing guide groove.

[0022] The stop guide protrusion includes a stop guide protrusion inclined surface formed in a manner that allows it to closely adhere to the inclined surface of the stop guide groove.

[0023] The mirror housing is capable of being switched from the first position to a third position folded in the opposite direction to the direction toward the second position, and the stop guide groove is provided in a plurality of such grooves. The range of angle change of the mirror housing according to the position switch between the first position and the third position includes the range of angle intervals between adjacent stop guide grooves in the plurality of stop guide grooves.

[0024] The stop guide protrusions are arranged in multiples at equal angular intervals, centered on the rotation axis of the mirror housing.

[0025] The base elastic portion is provided with a ring shape that is cut into part of it and includes opposing two ends.

[0026] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0027] Beneficial effects

[0028] According to the vehicle drive device of the present invention as described above, when the vehicle is in motion, the gap between the mirror housing and the base is made to fit as close as possible, thereby having the advantage of preventing wind noise caused by air.

[0029] Furthermore, it has the following advantages: when the mirror housing rotates relative to the base, a predetermined distance is maintained between the base and the mirror housing, thereby preventing friction noise between the base and the mirror housing. Attached Figure Description

[0065] Detailed Implementation

[0066] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention, as well as methods for implementing them, will become clear from the detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention can be implemented in various different forms and is not limited to the embodiments disclosed below. These embodiments are provided only to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the invention. The present invention is defined only by the scope of the claims. Throughout this specification, the same reference numerals refer to the same constituent elements.

[0067] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) are to be understood in the same sense as those skilled in the art to which this invention pertains. Furthermore, terms defined in commonly used dictionaries should not be interpreted ideally or excessively unless explicitly defined otherwise.

[0068] Figure 1 This is a diagram showing a vehicle equipped with a drive unit for vehicles according to an embodiment of the present invention. Figure 2 It is shown Figure 1 The image shown depicts a vehicle with its mirror housing folded. Figure 3 It is shown Figure 1 The diagram shown depicts the vehicle's mirror housing unfolded. Figure 4 It is shown Figure 1 The diagram shows the mirror housing of the vehicle folded in opposite directions.

[0069] Reference Figures 1 to 4 The vehicle 10 may include a mirror base 11, a mirror housing 12, and a vehicle drive unit 13.

[0070] The mirror base 11 can be fixed to the vehicle body to support the mirror housing 12. The mirror housing 12 can provide the driver with a side-rear view of the vehicle 10. For example, the mirror housing 12 may include at least one of a mirror and a camera. The mirror can provide a reflected image of the side-rear view of the vehicle 10, and the camera can generate a captured image of the side-rear view of the vehicle 10. The captured image generated by the camera can be a still image or a moving image.

[0071] The driver can confirm the view to the side and rear of the vehicle 10 by referring to the reflected image provided by the mirror or the image generated by the camera. In order to output the image generated by the camera, a display unit (not shown) capable of outputting the image can be provided inside the vehicle 10.

[0072] The vehicle drive unit 13 can generate a driving force to rotate the mirror housing 12 relative to the mirror base 11. The vehicle drive unit 13 can be mounted on either the mirror base 11 or the mirror housing 12. Hereinafter, the case where the vehicle drive unit 13 is mounted on the mirror housing 12 will be described in detail.

[0073] Reference Figures 2 to 4 The mirror housing 12 can be folded or unfolded relative to the mirror base 11.

[0074] In this utility model, the folding of the mirror housing 12 means, as follows: Figure 2 As shown, the mirror housing 12 rotates relative to the mirror base 11 so that the outer end of the mirror housing 12 is close to the vehicle body. When the vehicle 10 is parked or passing through a narrow space, the mirror housing 12 is folded to ensure lateral space for the vehicle 10.

[0075] In this utility model, the unfolding of the mirror housing 12 means, as follows: Figure 3 As shown, the mirror housing 12 rotates relative to the mirror base 11 so that the outer end of the mirror housing 12 is away from the vehicle body. By unfolding the mirror housing 12 while the vehicle 10 is in motion, a side-rear view of the vehicle 10 can be provided to the driver.

[0076] like Figure 4 As shown, the mirror housing 12 can also be directed towards... Figure 2 Fold in the opposite direction to the folding direction shown. When pedestrians, surrounding vehicles, or surrounding objects exert external force on the mirror housing 12, the mirror housing 12 can be folded into... Figure 4 The shape shown is to prevent damage or breakage to pedestrians, surrounding vehicles, surrounding objects, and the mirror housing 12. Below, Figure 4 The fold shown is called a reverse fold.

[0077] In this utility model, as follows Figure 3 The position of the mirror housing 12, which is extended relative to the mirror base 11 to provide the driver with a side-rear view of the vehicle 10, is referred to as the first position. Figure 2 The position of the mirror housing 12, which is folded relative to the mirror base 11 to ensure lateral space in the vehicle 10, is referred to as the second position. Figure 4 The position of the mirror housing 12 that is folded in the opposite direction relative to the mirror housing 12 in order to prevent damage or breakage to surrounding objects and the mirror housing 12 is called the third position.

[0078] The mirror housing 12 can be converted to a first position unfolded relative to the mirror base 11 or a second position folded relative to the mirror base 11, and can also be converted to a third position by means of external force.

[0079] Figure 5 This diagram shows a space formed between the mirror base and the mirror housing. Figure 6 This is a diagram showing the mirror housing near the mirror base. Figure 7 This is a diagram showing the mirror housing being folded.

[0080] Reference Figures 5 to 7 The mirror housing 12 can be supported by the mirror base 11.

[0081] Figure 5 This illustrates a case where a space SP is formed between the mirror housing 12 and the mirror base 11. Furthermore, if the gap between the mirror housing 12 and the mirror base 11 is too large, air may flow into the corresponding space SP during vehicle 10 operation, potentially generating wind noise.

[0082] Figure 6 The diagram shows the mirror housing 12 and the mirror base 11 arranged closely together. If the mirror housing 12 is rotated while it is too close to the mirror base 11, friction noise may be generated due to the friction between the mirror housing 12 and the mirror base 11.

[0083] Thus, if the gap between the mirror housing 12 and the mirror base 11 is too large or too small, wind noise or friction noise may be generated.

[0084] According to an embodiment of the present invention, the vehicle drive device 13 can rotate the mirror housing 12 relative to the mirror base 11 in a manner that prevents the generation of wind noise or friction noise. Specifically, when the mirror housing 12 is in a first position, the vehicle drive device 13 can keep the mirror housing 12 tightly against the mirror base 11. Furthermore, as... Figure 7 As shown, when the position of the mirror housing 12 changes from the first position to the second position, the vehicle drive device 13 can separate the mirror housing 12 from the mirror base 11 by a predetermined distance. As the mirror housing 12 rotates at the predetermined distance from the mirror base 11, friction noise can be prevented. Furthermore, when the mirror housing 12 is in the second position, since the vehicle is not in motion, it is not a problem for a space SP to form between the mirror housing 12 and the mirror base 11.

[0085] Figure 8 This is a perspective view of a vehicle drive device according to an embodiment of the present invention. Figure 9 This is an exploded perspective view of a vehicle drive device according to an embodiment of the present invention. Figure 10This diagram illustrates the connection between the fixing part and the driving part when the mirror housing is in the first position. Figure 11 This diagram illustrates the connection between the fixing part and the driving part when the mirror housing is in the second position.

[0086] Reference Figure 8 and Figure 9 According to an embodiment of the present invention, the vehicle drive device 13 is configured to include a fixing part 100, a drive part 200, and a base elastic part 300.

[0087] The fixing part 100 can be fixed to the mirror base 11 of the vehicle 10. Furthermore, the fixing part 100 can provide a rotation reference for the drive part 200. The drive part 200 can be rotatably coupled to the fixing part 100 and can rotate about the rotation axis of the fixing part 100.

[0088] The drive unit 200 can be fixed to the mirror housing 12 of the vehicle 10, and can rotate relative to the fixing part 100 by generating a driving force. As the drive unit 200 rotates relative to the fixing part 100, the mirror housing 12 can rotate relative to the mirror base 11.

[0089] When the position of the mirror housing 12 changes from the second position to the first position, the drive unit 200 can bring the mirror housing 12 closer to the mirror base 11 at a predetermined reference interval. Here, the reference interval may include 0. For example, when the mirror housing 12 is in the first position, the drive unit 200 can press the mirror housing 12 tightly against the mirror base 11. Arranging the mirror housing 12 closer to the mirror base 11 can prevent the generation of wind noise.

[0090] When the mirror housing 12 is in the first position, such as Figure 10 As shown, the fixing part 100 can be fully inserted into the driving part 200, thereby reducing the gap between the mirror housing 12 and the mirror base 11.

[0091] Furthermore, when the position of the mirror housing 12 changes from the first position to the second position, the drive unit 200 can separate the mirror housing 12 from the mirror base 11 at a distance greater than the reference interval. When the mirror housing 12 moves from the first position to the second position, as... Figure 11 As shown, the drive unit 200 rises a predetermined distance G relative to the fixed unit 100, thereby separating the mirror housing 12 from the mirror base 11. With the mirror housing 12 separated from the mirror base 11, friction noise between the mirror housing 12 and the mirror base 11 can be prevented.

[0092] The base elastic portion 300 can be disposed between the fixed portion 100 and the driving portion 200 to generate an elastic force in the direction that pushes the driving portion 200 relative to the fixed portion 100. When the mirror housing 12 moves from the first position to the second position or from the second position to the first position, the base elastic portion 300 prevents the driving portion 200 from descending to the fixed portion 100, and the mirror housing 12 and the mirror base 11 can remain separated.

[0093] Figure 12 This is a three-dimensional view of the fixed part. Figure 13 This diagram shows the fixing part combined with the base elastic part. Figure 14 This diagram shows the fixing part connected to the support plate.

[0094] Reference Figures 12 to 14 The fixing part 100 can be formed by stacking multiple cylinders 110, 120, 130 with different diameters.

[0095] The plurality of cylinders 110, 120, and 130 may include a first cylinder 110, a second cylinder 120, and a third cylinder 130. The central axes of the first cylinder 110, the second cylinder 120, and the third cylinder 130 may be the same. Here, the central axis Ax of the first cylinder 110, the second cylinder 120, and the third cylinder 130 is either the rotation axis relative to the mirror housing 12 of the mirror base 11 or the rotation axis relative to the drive unit 200 of the fixing part 100. Hereinafter, the rotation axis Ax refers to the aforementioned central axis Ax.

[0096] The first cylinder 110 can be fixedly coupled to the mirror base 11. The first cylinder 110 may include an elastic portion mounting surface 111 and fixed guide protrusions 112. The elastic portion mounting surface 111 may be formed in a direction toward the drive portion 200. Multiple fixed guide protrusions 112 may be formed in a ring shape protruding along the edge of the elastic portion mounting surface 111. Multiple fixed guide protrusions 112 may be formed in a direction toward the drive portion 200. Multiple fixed guide protrusions 112 may be arranged at the same interval. A fixed guide groove may be formed between two adjacent fixed guide protrusions 112.

[0097] The two ends of the fixed guide protrusion 112 may be formed with fixed guide protrusion inclined surfaces 112a. The fixed guide protrusion inclined surfaces 112a can guide the drive body 210 equipped in the drive unit 200 (see reference). Figure 15 The drive guide protrusion 214 (refer to) Figure 18 The movement of the mirror housing 12. When the mirror housing 12 changes position between the first position and the second position or between the first position and the third position, the drive guide protrusion 214 is guided by the inclined surface 112a of the fixed guide protrusion, so that the drive body 210 can rise or fall relative to the fixed part 100.

[0098] The second cylinder 120 has a smaller diameter than the first cylinder 110 and can protrude from the first cylinder 110 in a direction toward the drive unit 200. The second cylinder 120 is engaged with the drive body 210 of the drive unit 200 and can provide a rotation reference for the drive body 210. The drive body 210 can rotate about the rotation axis Ax while engaged with the second cylinder 120.

[0099] Furthermore, the second cylinder 120 can provide a drive body 210 and a stop ring 220 (see reference). Figure 15 The moving reference is that the drive body 210 and the stop ring 220 can move along the rotation axis Ax while being in close contact with the outer peripheral surface of the second cylinder 120.

[0100] To provide a movement path for the stop ring 220, a movement guide groove 121 may be formed in the second cylinder 120. The movement guide groove 121 may be formed by recessing the outer surface of the second cylinder 120. The movement guide groove 121 may be formed elongated in the direction of the rotation axis Ax. As described later, the stop ring 220 may be formed with a movement guide protrusion 222 that can be inserted into the movement guide groove 121 (see reference). Figure 19 With the movable guide protrusion 222 inserted into the movable guide groove 121, the stop ring 220 can move in the direction of the rotation axis Ax.

[0101] Reference Figure 13 The base elastic part 300 can pass through the second cylinder 120 and be placed in the first cylinder 110.

[0102] The base elastic portion 300 can be disposed on the elastic portion mounting surface 111. The base elastic portion 300 may include a wave spring provided in a ring shape. The base elastic portion 300 can pass through the second cylinder 120 and be disposed on the elastic portion mounting surface 111. The base elastic portion 300 can apply an elastic force in an upward direction relative to the elastic portion mounting surface 111. Specifically, the base elastic portion 300 can provide an elastic force to the drive body 210 relative to the fixing portion 100.

[0103] The base elastic portion 300 is provided with an annular shape that is cut off as a part of it and includes opposing two ends. Thus, regardless of the shape of the base elastic portion 300 according to the distance between the bottom surface of the first cylinder 110 and the drive body 210, the diameter of the base elastic portion 300 remains constant, and the engagement between the base elastic portion 300 and the second cylinder 120 can be firmly maintained.

[0104] Reference Figure 12 and Figure 14The third cylinder 130 has a smaller diameter than the second cylinder 120 and can protrude from the second cylinder 120 toward the drive unit 200.

[0105] Drive gear 230 of drive unit 200 (see reference) Figure 15 This allows the third cylinder 130 to be engaged. The drive gear 230 can move in the direction of the rotation axis Ax while the third cylinder 130 is engaged.

[0106] Drive elastic part 250 of drive unit 200 (see reference) Figure 15 This allows the third cylinder 130 to pass through. The drive elastic part 250 can be provided in the form of a coil spring, into which the third cylinder 130 can be inserted.

[0107] The elastic force of the drive elastic section 250 can be formed along the direction of the rotation axis Ax. For example, the elastic force of the drive elastic section 250 can be formed from the upper part of the third cylinder 130 toward the second cylinder 120. For this purpose, a support plate 140 supporting the drive elastic section 250 can be provided in the third cylinder 130. As the support plate 140 supports the upper end of the drive elastic section 250, the elastic force of the drive elastic section 250 can be formed from the upper part of the third cylinder 130 toward the second cylinder 120. One side of the drive elastic section 250 can contact the support plate 140, and the other side can contact the drive gear 230. Finally, the elastic force of the drive elastic section 250 can be provided to the drive gear 230.

[0108] To enable the support plate 140 to support the drive elastic part 250, the U-shaped clamp 150 can engage with the third cylinder 130. The U-shaped clamp 150 can engage with the third cylinder 130 while the support plate 140 is inserted into it. The U-shaped clamp 150 is inserted into the clamping groove 131 formed in the third cylinder 130, thereby enabling engagement between the U-shaped clamp 150 and the third cylinder 130. The U-shaped clamp 150 prevents the support plate 140 from moving upwards. Thus, the support plate 140 can support the drive elastic part 250.

[0109] Figure 15 This is an exploded 3D view of the drive unit.

[0110] Reference Figure 15 The drive unit 200 is configured to include a drive body 210, a stop ring 220, a drive gear 230, a transmission gear 240, a drive elastic part 250, a drive motor 260, and a drive cover 270.

[0111] The drive body 210 can be fixed to the mirror housing 12 and can be rotatably connected to the fixing part 100. That is, the drive body 210 can rotate with the fixing part 100 as a reference.

[0112] The drive body 210 can be combined with the drive cover 270 to provide a receiving space 211 for accommodating the stop ring 220, drive gear 230, transmission gear 240, drive elastic part 250, and drive motor 260. The drive body 210 and drive cover 270 can be joined by a connecting unit (not shown) such as screws. Therefore, except for the drive body 210 and drive cover 270, the stop ring 220, drive gear 230, transmission gear 240, drive elastic part 250, and drive motor 260 housed in the drive body 210 can operate as a single unit.

[0113] The drive motor 260 can generate driving force, thereby causing the drive body 210 to rotate relative to the fixed part 100. As the drive body 210 rotates, the drive part 200 as a whole rotates relative to the fixed part 100.

[0114] The following is through Figures 16 to 26 The shape and function of each component constituting the drive unit 200 are described in detail.

[0115] Figure 16 It is a 3D view of the driving body. Figure 17 This is a plan view of the driving unit. Figure 18 This is a three-dimensional view of the bottom surface of the driving body.

[0116] Reference Figures 16 to 18 The drive body 210 is configured to include a receiving space 211, a through hole 212, a drive reference surface 215, a stop guide protrusion 213, an elastic part contact surface 216, and a drive guide protrusion 214.

[0117] The receiving space 211 can accommodate a stop ring 220, a drive gear 230, a transmission gear 240, a drive elastic part 250, and a drive motor 260. In this utility model, the receiving space 211 can be a connecting space within the internal space of the drive body 210, which can simultaneously arrange the stop ring 220, the drive gear 230, the transmission gear 240, the drive elastic part 250, and the drive motor 260.

[0118] The through hole 212 allows the second cylinder 120 of the fixing part 100 to pass through. The drive body 210 can rotate with the rotation axis Ax as a reference while the first cylinder 110 is mounted on the fixing part 100.

[0119] The drive reference surface 215 can be formed on the inner bottom side of the drive body 210 facing the stop ring 220. The stop guide protrusion 213 can be formed from the drive reference surface 215. Specifically, the stop guide protrusion 213 can be formed from the drive reference surface 215 facing the stop ring 220.

[0120] The stop guide protrusion 213 may include a stop guide protrusion inclined surface 213a. The stop guide protrusion inclined surface 213a may be formed to closely abut against the stop guide groove inclined surface 224a of the stop ring 220, which will be described later.

[0121] The stop guide protrusions 213 can be provided in multiples at equal angular intervals centered on the rotation axis Ax of the mirror housing 12. Here, the multiple stop guide protrusions 213 provided at equal angular intervals can be arranged at the same distance from the rotation axis Ax. For example, the multiple stop guide protrusions 213 can be arranged at intervals of 120 degrees or 180 degrees centered on the rotation axis Ax of the mirror housing 12. Figure 17 Two stop guide protrusions 213 are arranged at a first distance D1 relative to the rotation axis Ax at a 180-degree interval, and two stop guide protrusions 213 are arranged at a second distance D2 relative to the rotation axis Ax at a 180-degree interval.

[0122] The elastic contact surface 216 can contact the base elastic part 300. The drive body 210 can receive the elastic force of the base elastic part 300 through the elastic contact surface 216.

[0123] Multiple drive guide protrusions 214 may be formed in a ring shape protruding along the edge of the elastic contact surface 216. As described above, the fixing part 100 may include fixing guide protrusions 112 and fixing guide grooves. When the mirror housing 12 is in a first position, each of the multiple drive guide protrusions 214 can be inserted into the fixing guide groove formed between adjacent fixing guide protrusions 112. And when the mirror housing 12 is in a second position, each of the multiple drive guide protrusions 214 can be released from the corresponding fixing guide groove.

[0124] Additionally, a base elastic portion 300 may be provided between the fixing portion 100 and the drive body 210. During the transition of the mirror housing 12 from the second position to the first position, the drive body 210 is restricted by the base elastic portion 300 to approach the fixing portion 100, thereby preventing each of the plurality of drive guide protrusions 214 from inserting into the corresponding fixing guide groove. Thus, during the transition of the mirror housing 12 from the second position to the first position, the drive body 210 is prevented from falling toward the fixing portion 100 due to gravity.

[0125] Figure 19 This is a 3D diagram of the retaining ring. Figure 20 This is a three-dimensional view of the bottom surface of the retaining ring. Figure 21 This is a bottom view of the retaining ring. Figure 22 It is a diagram used to illustrate the connection relationship between the drive body and the stop ring.

[0126] Reference Figures 19 to 21The stop ring 220 is configured to include a clutch groove 221, a movement guide protrusion 222, a stop reference surface 223, and a stop guide groove 224.

[0127] Clutch groove 221 can supply the clutch protrusion 231 of drive gear 230 (see reference) Figure 24 The clutch protrusion 231 is inserted into the clutch groove 221, thereby fixing the position of the drive gear 230 relative to the retaining ring 220.

[0128] The clutch groove 221 may include a clutch groove inclined surface 221a. The clutch groove inclined surface 221a and the clutch protrusion inclined surface 231a of the clutch protrusion 231 (see reference) Figure 24 The contact surface allows the movement of the clutch protrusion 231 to be guided.

[0129] The movable guide protrusion 222 can be formed by protruding inward from the inner side of the stop ring 220. For example... Figure 22 As shown, the movable guide protrusion 222 can be inserted into the movable guide groove 121 of the second cylinder 120 provided in the fixed part 100.

[0130] In this invention, the stop ring 220 can pass through the fixing portion 100 in a manner that blocks rotation along the rotation direction of the mirror housing 12 relative to the fixing portion 100 and is movable in the direction of the rotation axis Ax of the mirror housing 12. As the movable guide protrusion 222 is inserted into the movable guide groove 121, rotation of the stop ring 220 relative to the fixing portion 100 can be prevented. The movable guide groove 121 can be formed relatively long in the direction of the rotation axis Ax to allow movement of the movable guide protrusion 222. Therefore, the stop ring 220 can move in the direction of the rotation axis Ax while passing through the fixing portion 100.

[0131] Reference Figure 20 and Figure 21 The stop reference surface 223 can be formed on the lower side of the stop ring 220.

[0132] The stop reference surface 223 can be formed toward the drive body 210. The stop guide groove 224 can be formed by making the edge of the stop reference surface 223 recessed in an arc shape.

[0133] The stop guide groove 224 provides a movement path for the stop guide protrusion 213 equipped on the drive body 210. With the stop guide protrusion 213 inserted into the stop guide groove 224, the drive body 210 can rotate about the rotation axis Ax.

[0134] The stop guide groove 224 may include a stop guide groove inclined surface 224a that is inclined relative to the rotation axis Ax of the mirror housing 12. The stop guide groove inclined surface 224a can change the direction of movement of the stop guide protrusion 213 of the drive body 210.

[0135] When the mirror housing 12 is in the first position, the stop guide protrusion 213 is spaced apart from the stop guide groove 224 by a predetermined distance. When the mirror housing 12 is in the second position, the stop guide protrusion 213 can remain inserted into the stop guide groove 224.

[0136] Multiple stop guide grooves 224 can be provided. For example, the stop guide grooves 224 can be provided on both sides with the rotation axis Ax as the center. Figure 21 The diagram illustrates the configuration of two stop guide grooves 224 arranged at a third distance D3 relative to the rotation axis Ax and two stop guide grooves 224 arranged at a fourth distance D4 relative to the rotation axis Ax, both fitted onto the stop ring 220. The two stop guide grooves 224 arranged at the third distance D3 provide the movement path for the two stop guide protrusions 213 arranged at the first distance D1, and the two stop guide grooves 224 arranged at the fourth distance D4 provide the movement path for the two stop guide protrusions 213 arranged at the second distance D2.

[0137] As described above, the mirror housing 12 can perform position transitions between a first position and a third position. The angular variation range B of the mirror housing 12 according to the position transition between the first and third positions (refer to...) Figure 33 This can include the angular interval range A between adjacent stop guide grooves 224 in a plurality of stop guide grooves 224. Here, adjacent stop guide grooves 224 refer to stop guide grooves 224 arranged at the same distance relative to the central axis. See reference Figure 21 The angular interval range A between the two stop guide grooves 224 arranged at the fourth distance D4 may include the angular variation range B of the mirror housing 12.

[0138] When the mirror housing 12 is in the third position, the stop guide protrusion 213 can disengage from the stop guide groove 224 and abut against the stop reference surface 223 (hereinafter referred to as the intermediate reference surface) formed between the stop guide grooves 224 by the rotation of the drive body 210. In this state, when the mirror housing 12 returns to the first position, the stop guide protrusion 213 can be inserted into the original stop guide groove 224 by the rotation of the drive body 210.

[0139] Furthermore, if the stop guide protrusion 213 passes through the intermediate reference surface and is inserted into a stop guide groove 224 that is not the original stop guide groove 224, it may not be easy to perform the operation of disengaging from the corresponding stop guide groove 224. (Refer to...) Figure 21 To explain, if the stop guide protrusion 213, which has detached from the upper stop guide groove 224, is inserted into the lower stop guide groove 224, it may not be easy to detach from the lower stop guide groove 224. To prevent the stop guide protrusion 213 from being inserted into another stop guide groove 224 that is not the original stop guide groove 224, the angle change range B of the mirror housing 12, depending on the position transition between the first and third positions, can include the angle interval range A between adjacent stop guide grooves 224. By rotating the mirror housing 12 to determine the position of the stop guide protrusion 213, and since the angle change range B of the mirror housing 12 includes the angle interval range A between adjacent stop guide grooves 224, it is possible to prevent the stop guide protrusion 213 from being inserted into another stop guide groove 224 that is not the original stop guide groove 224.

[0140] Figure 23 It is a 3D diagram of the drive gear. Figure 24 This is a three-dimensional view of the bottom surface of the drive gear. Figure 25 This diagram shows the engagement of the retaining ring and the drive gear. Figure 26 This diagram shows the situation where the engagement between the retaining ring and the drive gear is released.

[0141] Reference Figure 23 and Figure 24 The drive gear 230 can be provided in a ring shape and can be rotated with respect to the rotation axis Ax of the mirror housing 12 by the driving force of the drive motor 260.

[0142] The drive gear 230 may include a clutch protrusion 231. The clutch protrusion 231 may be inserted into the clutch groove 221 of the stop ring 220. By inserting the clutch protrusion 231 into the clutch groove 221, the position of the drive gear 230 relative to the stop ring 220 can be fixed.

[0143] The clutch protrusion 231 may include a clutch protrusion inclined surface 231a. The clutch protrusion inclined surface 231a may contact the clutch groove inclined surface 221a of the clutch groove 221.

[0144] The drive gear 230 may include a plurality of clutch protrusions 231. The plurality of clutch protrusions 231 may be arranged at positions corresponding to a plurality of clutch slots 221. Specifically, the plurality of clutch protrusions 231 may be arranged along the circumferential direction of the drive gear 230 such that adjacent ones are spaced at the same interval.

[0145] The drive gear 230 may include an upper end face 232 and a lower end face 233. The upper end face 232 and the lower end face 233 may be provided in a ring shape. The upper end face 232 may face the drive elastic part 250, and the lower end face 233 may face the stop ring 220. The upper end face 232 can provide the elastic force of the drive elastic part 250, and the lower end face 233 can perform the engagement of the drive gear 230 and the stop ring 220.

[0146] The lower end face 233 can remain in close contact with the upper face of the stop ring 220, so the elastic force of the drive elastic part 250 can be transmitted to the stop ring 220.

[0147] Reference Figure 25 and Figure 26 The stop ring 220 and the drive gear 230 can be engaged or disengaged.

[0148] When the stop ring 220 and the drive gear 230 are engaged, the clutch protrusion 231 of the drive gear 230 can be inserted into the clutch groove 221 of the stop ring 220. When the engagement between the stop ring 220 and the drive gear 230 is disengaged, the clutch protrusion 231 of the drive gear 230 can be released from the clutch groove 221 of the stop ring 220. The disengagement of the stop ring 220 and the drive gear 230 can be performed by rotating the drive gear 230. The stop ring 220 can be prevented from rotating relative to the fixed part 100. In this state, when the drive gear 230 rotates relative to the fixed part 100, the clutch protrusion 231 can move along the clutch groove inclined surface 221a of the clutch groove 221. At this time, while the drive gear 230 disengages from the stop ring 220, the drive gear 230 moves in the direction of the rotation axis Ax.

[0149] The rotation of the drive gear 230 can be performed when the position of the mirror housing 12 changes from the first position to the third position. When the position of the mirror housing 12 changes from the first position to the third position by external force, the drive gear 230 rotates and moves upward. The elastic force of the drive elastic part 250 can be provided through the upper end face 232 of the drive gear 230. As the drive gear 230 rises, the elastic force increases, and this elastic force can act as a force that opposes the rotation of the mirror housing 12.

[0150] Figure 27 It is a diagram used to illustrate the transmission of driving force from the drive motor to the drive gear.

[0151] Reference Figure 27 The driving force of the drive motor 260 can be transmitted to the drive gear 230 through the transmission gear 240.

[0152] The transmission gear 240 can transmit the driving force of the drive motor 260 to the drive gear 230. The transmission gear 240 may include a first transmission gear 241 and a second transmission gear 242. The first transmission gear 241 and the second transmission gear 242 may have the same axis of rotation and may be fixed to each other. The first transmission gear 241 may be provided in the form of a worm, and the second transmission gear 242 may be provided in the form of a worm gear.

[0153] In this invention, the drive gear 230 can be provided in the form of a worm gear. Furthermore, the pinion 261 of the drive motor 260 can be provided in the form of a worm. Therefore, the first transmission gear 241 can mesh with the drive gear 230, and the second transmission gear 242 can mesh with the pinion 261.

[0154] The driving force of the drive motor 260 can be transmitted to the drive gear 230 via the pinion 261, the second transmission gear 242, and the first transmission gear 241. Rotation of the drive gear 230 relative to the stop ring 220 can be blocked. When the drive gear 230 is in close contact with the stop ring 220 via the drive elastic part 250, rotation of the drive gear 230 relative to the stop ring 220 can be blocked by the engagement between the clutch protrusion 231 and the clutch groove 221. With rotation of the drive gear 230 relative to the stop ring 220 blocked, the rotational force of the drive motor 260 can be used to rotate the drive body 210 relative to the drive gear 230. As the drive body 210 rotates, rotation of the mirror housing 12 relative to the mirror base 11 can be performed. Specifically, the mirror housing 12 can be switched between a first position and a second position by the rotational force of the drive motor 260.

[0155] Figure 28 This is a diagram showing the mirror housing in the second position. Figure 29 This is a diagram showing the interior of the drive unit when the mirror housing is in the second position.

[0156] Reference Figure 28 and Figure 29 When the mirror housing 12 is in the second position, the drive body 210 can be separated from the fixing part 100 by a predetermined distance.

[0157] When the mirror housing 12 is in the second position, the drive guide protrusion 214 of the drive body 210 is released from the fixed guide groove formed between the fixed guide protrusions 112, and the stop guide protrusion 213 can be inserted into the stop guide groove 224 of the stop ring 220.

[0158] The drive gear 230 and the stop ring 220 can be stacked. The drive elastic part 250 can provide an elastic force to the drive gear 230. The elastic force of the drive elastic part 250 can be transmitted from the drive gear 230 to the stop ring 220, and from the stop ring 220 to the drive body 210.

[0159] A base elastic portion 300 may be provided between the fixing portion 100 and the drive body 210. The base elastic portion 300 can act as a force that pushes the drive body 210 upward. By preventing the drive body 210 from falling, the base elastic portion 300 can maintain the distance between the fixing portion 100 and the drive body 210.

[0160] Figure 30 This is a diagram showing the mirror housing changing from the second position to the first position. Figure 31 This is a diagram showing the interior of the drive unit when the mirror housing is switched from the second position to the first position. Figure 32 This is a diagram illustrating the scenario where the driving body descends.

[0161] Reference Figures 30 to 32 The position of the mirror housing 12 can be changed from the second position to the first position.

[0162] The position change of the mirror housing 12 can be performed by the driving force of the drive motor 260. The driving force of the drive motor 260 can be transmitted to the drive gear 230 through the transmission gear 240. The drive gear 230 is engaged with the stop ring 220, thus restricting the rotation of the drive gear 230. In this state, when the driving force of the drive motor 260 is transmitted to the drive gear 230, the drive body 210 can rotate around the drive gear 230 by means of this driving force. At this time, the drive body 210 can move in the direction of the rotation axis Ax of the mirror housing 12.

[0163] As the drive body 210 rotates, the stop guide protrusion 213 of the drive body 210 can move along the stop guide groove 224 of the stop ring 220. The stop guide protrusion 213 can reach the end of the stop guide groove 224. The end of the stop guide groove 224 can be formed with a stop guide groove inclined surface 224a.

[0164] When the position of the mirror housing 12 changes from the second position to the first position, the stop guide protrusion 213 is guided by the stop guide groove inclined surface 224a, and the drive body 210 can approach the fixing part 100. At this time, with the stop guide protrusion inclined surface 213a in close contact with the stop guide groove inclined surface 224a, as the stop guide protrusion 213 continues to move, it is guided by the stop guide groove inclined surface 224a, thereby driving the body 210 to descend. As the drive body 210 descends, each of the plurality of drive guide protrusions 214 provided on the drive body 210 can be inserted into the corresponding fixing guide groove. With the drive guide protrusion 214 inserted into the fixing guide groove, movement of the drive body 210 relative to the fixing part 100 can be prevented.

[0165] Figure 33 This is a diagram showing the mirror housing changing from the first position to the third position. Figure 34 This is a diagram showing the interior of the drive unit when the mirror housing is switched from the first position to the third position.

[0166] Reference Figure 33 and Figure 34 The position of the mirror housing 12 can be changed from the first position to the third position.

[0167] When a pedestrian, surrounding vehicle, or surrounding object applies an external force to the mirror housing 12, the position of the mirror housing 12 can change from a first position to a third position. The external force acting on the mirror housing 12 can be transmitted to the drive body 210. In this case, the external force can act as a force that rotates the drive body 210 with respect to the rotation axis Ax.

[0168] When an external force is applied to the drive body 210 to rotate relative to the fixed part 100, the drive gear 230 rotates together with the drive body 210, and the drive body 210 can move in the direction of the rotation axis Ax of the mirror housing 12. The drive body 210 is guided by the fixed guide protrusion 112 of the fixed part 100, and can rotate and rise with the rotation axis Ax as a reference.

[0169] The first transmission gear 241 can mesh with the drive gear 230. When the drive body 210 rotates with respect to the rotation axis Ax of the mirror housing 12, the drive gear 230 can be pushed by the first transmission gear 241 and rotate together with the drive body 210. External force is transmitted to the drive gear 230 through the first transmission gear 241, thereby driving the drive gear 230 to rotate.

[0170] As the drive gear 230 rotates, the stop ring 220 coupled to the drive gear 230 can move in the direction of the rotation axis Ax. As the stop guide protrusion 213 of the drive body 210 presses against the intermediate reference surface of the stop ring 220, the stop ring 220 can rise in the direction toward the drive elastic portion 250. The drive elastic portion 250 can apply an elastic force to the stop ring 220. As the stop ring 220 rises, the drive elastic portion 250 can be compressed, and the elastic force can increase.

[0171] Furthermore, as the drive gear 230 rotates relative to the stop ring 220, the engagement between the drive gear 230 and the stop ring 220 is released. The drive gear 230 can then rise relative to the stop ring 220 in the direction toward the drive elastic portion 250. The drive elastic portion 250 can apply an elastic force to the drive gear 230. As the drive gear 230 rises, the drive elastic portion 250 is compressed, and the elastic force can increase.

[0172] Ultimately, the drive elastic part 250 can be compressed to the rising distance of the stop ring 220 relative to the fixed part 100 and the rising distance of the drive gear 230 relative to the stop ring 220, thereby increasing the elastic force.

[0173] The increased elastic force from the drive elastic section 250 can act in the opposite direction to the rotation of the drive section 200. That is, the external force used to rotate the drive section 200 should be greater than the increased elastic force. The user can rotate the mirror housing 12 relative to the mirror base 11 to a third position by applying a force greater than the increased elastic force to the mirror housing 12.

[0174] As described above, the angular variation range B of the mirror housing 12 according to the position transition between the first position and the third position can include the angular interval range A between adjacent stop guide grooves 224 in the plurality of stop guide grooves 224. For example, by providing a separate stop (not shown), the angular variation range B of the mirror housing 12 can be constantly limited. Therefore, it is possible to prevent the stop guide protrusion 213 from being inserted into other stop guide grooves 224 that are not the original stop guide groove 224.

[0175] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical concept or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
