Description

Technical Field

[0001] This invention relates to a rearview mirror device. Background Technology

[0002] In conventional rearview mirror devices, as described in Patent Document 1, a rearview mirror device with an electric rotating unit is known to automatically rotate the rearview mirror between a usable position and a stored position.

[0003] The rearview mirror assembly includes: a rearview mirror body with a mirror; a mirror mount protruding from the side door in the vehicle width direction; and an electric rotating unit and a mirror adjustment unit housed within the rearview mirror body. The mirror mount is a portion having a base end and a front end, extending in the vehicle width direction, and forming an arm portion of the rearview mirror. The base end of the mirror mount is fixed to the side door, and the rearview mirror body is mounted on the front end of the mirror mount in a manner rotatable about a rotation axis extending in the vertical direction.

[0004] The rearview mirror body is driven by the rotation of an internally housed electric rotating unit, which rotates through the front end of the mirror mount, allowing it to rotate between a usable position and a stowed position. The usable position refers to the position where the rearview mirror body protrudes outwards from the front end of the mirror mount in the width direction of the vehicle, and is visible to the naked eye from inside the cabin. The stowed position refers to the position where the rearview mirror body extends approximately parallel to the side door.

[0005] In addition, the mirror adjustment unit housed in the rearview mirror body can finely adjust the mirror angle in both the horizontal and vertical directions when the rearview mirror body is stationary in the mirror usage position.

[0006] Existing technical documents

[0007] Patent document: Patent document 1: Japanese Patent Application Publication No. 2020-179680. Summary of the Invention

[0008] The technical problem that the invention aims to solve

[0009] The aforementioned rearview mirror device is a device in which the base of the mirror is fixed to the side door, and the main body of the rearview mirror rotates through the front end of the mirror base. Therefore, if the vehicle design requires the mirror base to be long in the width direction, when the mirror is folded up, even if the main body of the rearview mirror is rotated to the folded position, the mirror base will still protrude from the door panel, thus failing to fully meet the requirement of reducing the vehicle width when the mirror is folded up.

[0010] Furthermore, in the aforementioned device, the rearview mirror body contains an electric retraction unit. As a result, the vertical torque generated at the position of the electric rotating unit increases proportionally to the length of the mirror base, which can lead to increased mirror vibration when the vehicle is in motion.

[0011] Furthermore, because the rearview mirror body houses the electric rotating unit, the front-to-back width of the rearview mirror body (i.e., the width of the vehicle in the front-to-back direction) is large, which may obstruct the visibility when looking from the cabin.

[0012] While removing the electric rotation unit and mirror adjustment unit from the rearview mirror can solve the above-mentioned technical problems, it would require manually storing the main body of the rearview mirror and manually adjusting the mirror, which would reduce convenience.

[0013] In view of the above, the present invention aims to provide a rearview mirror device that can simultaneously and effectively reduce the vehicle width when the mirror is stowed, suppress mirror vibration during vehicle movement, improve visibility from the cabin, and has an electrically operated rotating unit that simplifies the mirror adjustment unit.

[0014] Technical means to solve technical problems

[0015] To solve the above-mentioned technical problems, the rearview mirror device of the present invention is a rearview mirror device on a vehicle side door, characterized in that it includes: a rearview mirror body having a mirror for obtaining a rear view of the vehicle; a mirror base having a front end fixed to the rearview mirror body and a base end away from the front end; a rotation support shaft connected to the base end of the mirror base and supporting the rearview mirror body and the mirror base so that it can freely rotate between a mirror use position where the mirror can be seen by the naked eye from the cabin and a storage position located inside the vehicle width direction of the mirror use position; and an electric rotation unit that rotates the rearview mirror body and the mirror base about the axis of the rotation support shaft so that it can rotate between the mirror use position and the storage position. The control unit controls the electric rotation unit, which is located on the side door. When a storage operation signal is input to initiate the storage action, the control unit controls the electric rotation unit to rotate the rearview mirror body and the mirror mount from the mirror usage position to the storage position. When an unfolding operation signal is input to initiate the unfolding action, the control unit controls the electric rotation unit to rotate the rearview mirror body and the mirror mount from the storage position to the mirror usage position. Furthermore, when a mirror adjustment signal is input to adjust the mirror surface, the control unit controls the electric rotation unit to rotate the rearview mirror body and the mirror mount within a small range based on the mirror usage position, thereby changing the angle of the mirror.

[0016] According to the above solution, in a rearview mirror assembly including a rearview mirror body with a mirror and a mirror mount fixed to the front end of the rearview mirror body, an electric rotating unit rotates the mirror mount, along with the rearview mirror body, from the mirror usage position to the storage position. Therefore, with the rearview mirror body and mirror mount rotated to the storage position, the amount of protrusion of the rearview mirror body and mirror mount from the side door in the vehicle width direction can be reduced, thus minimizing the vehicle's width dimension.

[0017] Furthermore, the heavy electric rotating unit in this rearview mirror device is located inside the side door, so the input from the road surface when the vehicle is moving (i.e., the vibration or external force caused by the unevenness of the road surface) will reduce the torque generated in the rearview mirror in the vertical direction, thus suppressing the vibration of the mirror.

[0018] Furthermore, since the electric rotating unit is located in the side door, the front-to-back width of the rearview mirror body can be reduced compared to the previous rearview mirror device, which housed the electric rotating unit in the rearview mirror body, thus improving visibility from the cockpit.

[0019] Furthermore, upon receiving a mirror adjustment signal, the control unit controls the aforementioned electric rotation unit to rotate the rearview mirror body and mirror mount within a small range based on the mirror's usage position, thereby changing the mirror angle. This allows for horizontal mirror adjustment using the electric rotation unit, simplifying the mirror adjustment unit previously located on the rearview mirror body.

[0020] In the aforementioned rearview mirror device, preferably, the aforementioned rotating support shaft is configured to tilt toward the front of the vehicle as it extends upward, and tilt toward the outside in the vehicle width direction as it extends upward.

[0021] According to the above scheme, by rotating only the main body and the mirror mount around the axis of rotation, minute adjustments to the mirror surface can be made simultaneously in both the horizontal and vertical directions. That is, the vertical adjustment is minimized. Furthermore, the vertical adjustment range during mirror adjustment is reduced, resulting in a smaller range of motion for the mirror and contributing to a thinner main body.

[0022] In the aforementioned rearview mirror device, preferably, the rearview mirror device further includes a storage unit that stores position information related to the adjusted positions of the rearview mirror body and the mirror mount when the mirror adjustment signal is input to the control unit, causing the electric rotation unit to rotate the rearview mirror body and the mirror mount within the aforementioned small range to perform mirror adjustment; wherein, when the rearview mirror body and the mirror mount are in the aforementioned stowed position, the control unit controls the electric rotation unit when the aforementioned unfolding operation signal is input, so that when the rearview mirror body and the mirror mount are rotated from the aforementioned stowed position to the aforementioned mirror use position, the rearview mirror body and the mirror mount are positioned at the position corresponding to the position information stored in the aforementioned storage unit.

[0023] According to the above scheme, the position information of the rearview mirror body and mirror mount when the mirror surface has been adjusted is stored in the storage unit in advance. When the next unfolding signal is input, the control unit controls the electric rotation unit to position the rearview mirror body and mirror mount in the position corresponding to the position information stored in the storage unit. This saves the user the trouble of adjusting the mirror surface every time they perform an unfolding operation, improving convenience.

[0024] In the above-described rearview mirror device, preferably, when the positions of the rearview mirror body and the mirror mount are not changed by the drive of the electric rotation unit, the control unit controls the electric rotation unit to adjust the rearview mirror body and the mirror mount back to the positions corresponding to the position information stored in the storage unit.

[0025] According to the above solution, when the positions of the rearview mirror body and the mirror mount change without being driven by the electric rotation unit, the control unit controls the electric rotation unit to adjust the rearview mirror body and the mirror mount back to the positions corresponding to the position information stored in the storage unit. Therefore, when an external force acts on the rearview mirror body, causing it to rotate unexpectedly, the rearview mirror body can be automatically restored to its previous position before the rotation. This eliminates the need for increased rotational resistance to resist the external force causing the rearview mirror body to rotate, as required by conventional electric rotation units, thus reducing the rotational resistance of the electric rotation unit.

[0026] In the aforementioned rearview mirror device, preferably, the aforementioned "minor range" is a range within which the rearview mirror body and the mirror mount can rotate ±5 degrees relative to the mirror's operating position. According to the above solution, the "minor range" is the range within which the driver can adjust the mirror surface to view the vehicle body through the mirror when parking and to view traffic lines through the mirror when driving.

[0027] In the above-mentioned rearview mirror device, preferably, the rotating support shaft is fixed to the base end of the mirror mount and is driven by the rotational force from the electric rotating unit, so that it can rotate together with the mirror mount around the axis of the rotating support shaft.

[0028] According to the above scheme, the mirror mount can be rotated simply by rotating the rotating support shaft driven by the electric rotating unit, resulting in a simple rearview mirror structure.

[0053] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0054] Figures 1-2 A side door 1 of a vehicle in which the rearview mirror device of the present invention is shown. In this side door 1, a rearview mirror 2 is disposed near the waistline BL of the upper end 3a of the door panel 3 and is located on the rear side of the vehicle at the A pillar 4. The door opening 5, which is surrounded by the A pillar 4 and the waistline BL, is provided with a door glass 6.

[0055] like Figures 1-7 As shown, the rearview mirror device in the vehicle side door 1 according to this embodiment is an electrically powered and retractable rearview mirror 2 installed in the side door 1. Specifically, the main parts of the rearview mirror device include a rearview mirror body 11 and a mirror base 12 constituting the rearview mirror 2, an electric rotating unit 13 for rotating the rearview mirror body 11 and the mirror base 12, a control unit 40 for controlling the electric rotating unit 13, and a user operation detection unit 42 (all refer to...). Figure 7 The electric rotation unit 13 is located inside the side door 1.

[0056] Furthermore, the rearview mirror device of this embodiment also includes: a rotating support shaft 24 that supports the rearview mirror body 11 and the mirror base 12 so that they can rotate freely (see reference). Figures 11-12 ); the skeleton component inside the side door 1, namely the waistline reinforcement 21; the support component 22 that fixes the electric rotating unit 13 to the waistline reinforcement 21; and the cover component 27 located on the outside of the side door 1.

[0057] The following sections will describe the components of the rearview mirror device in turn.

[0058] like Figure 2 As shown, the rearview mirror body 11 includes a mirror 14 for obtaining a rear view of the vehicle and a housing 15. The mirror 14 is an optical mirror that reflects light and is mounted on the rear side of the housing 15 (specifically, on the side of the housing 15). Figure 3 (The mirror is positioned in position P1, facing the rearward side). Additionally, the housing 15 of the rearview mirror body 11 houses internal mechanisms 37 such as a mirror adjustment unit for adjusting the vertical Z-direction and vehicle width Y-direction angles of the mirror 14, or a defrosting unit for the mirror 14 (see reference). Figure 12 ).

[0059] Mirror mount 12 is the part that constitutes the arm of rearview mirror 2, such as Figures 3-6As shown, it includes a front end portion 12b fixed to the rearview mirror body portion 11 and a base end portion 12a away from the front end portion 12b.

[0060] More specifically, the rearview mirror body 11 is fixed to the front end 12b of the mirror base 12, and the mirror 14 extends substantially parallel to the mirror base 12.

[0061] The base end 12a of the mirror mount 12 is mounted on the side door 1, allowing the rearview mirror body 11 and the mirror mount 12 to rotate between a mirror use position P1, where the mirror 14 can be seen with the naked eye from the cabin, and a storage position P2, located inside the mirror use position P1 in the vehicle width direction Y. Thus, the rearview mirror 2, including the rearview mirror body 11 and the mirror mount 12, can be folded from the mirror use position P1 to the storage position P2 and unfolded from the storage position P2 back to the mirror use position P1.

[0062] In this embodiment, Figures 9-12 The rotating support shaft 24 shown is connected to the base end 12a of the mirror mount 12, and supports the rearview mirror body 11 and the mirror mount 12 in the mirror use position P1 (see reference). Figure 3 and Figure 5 ) and storage location P2 (refer to Figure 4 and Figure 6 They move freely between them.

[0063] The rotating support shaft 24 extends from the base end 12a into the side door 1 in an upright state and rotates by means of the electric rotating unit 13.

[0064] Specifically, such as Figures 9-12 As shown, a through hole 26 is formed in the door panel 3 (outer panel) constituting the outer side of the side door 1. The rotating support shaft 24 passes through the through hole 26 in the door panel 3 and connects with the output shaft 35 (described later) of the electric rotating unit 13 disposed in the space 20 inside the side door 1. Figure 12 They are connected in a coaxial manner.

[0065] The electric rotation unit 13 has a structure that allows the rearview mirror body 11 and the mirror mount 12 to rotate between the mirror use position P1 and the storage position P2. Specifically, as shown in... Figure 12As shown, the electric rotation unit 13 includes a sleeve 31, a motor 32, a reducer 33 that reduces the torque generated by the motor 32, a torque limiter 34, an output shaft 35 that outputs rotational driving force, and a rotation sensor 38 that serves as a rotation detection unit for detecting the rotational speed of the motor 32. The sleeve 31 houses the motor 32, reducer 33, torque limiter 34, output shaft 35, and rotation sensor 38. Furthermore, the sleeve 31 also houses a rotating support shaft 24 and a bearing 36 that supports the rotating support shaft 24 to allow it to rotate freely. Therefore, the main components of the electric rotation unit 13—the motor 32, reducer 33, torque limiter 34, output shaft 35, and rotation sensor 38—are arranged on the axis of the rotating support shaft 24. The output shaft 35 is connected to the rotating support shaft 24 and can rotate integrally with it.

[0066] Furthermore, when the motor 31 is working, if the rotating support shaft 24 generates excessive torque, the torque limiter 34 can block the torque transmission and suppress its load on the motor 32.

[0067] The preferred bearing 36 is a ball bearing or roller bearing that supports the rotating shaft 24 with relatively low rotational resistance.

[0068] The electric rotation unit 13 is fixed to the waistline reinforcement 21 by the support member 22.

[0069] The waistline reinforcement 21 is located inside the side door 1 and is a skeletal component constituting the frame of the side door 1. For example... Figure 7 As shown, the waistline reinforcement 21 is fixed to the interior door panel 7 inside the side door 1 (see reference). Figure 7 and Figure 12 The waistline BL extends in the vehicle longitudinal direction X along the lower edge of the side door 1 window (i.e., the lower edge of the door opening 5 where the door glass 6 is located). The waistline reinforcement 21 in this embodiment is made of extruded aluminum material.

[0070] Specifically, support member 22 is as follows: Figures 8-12 As shown, it includes a semi-cylindrical mounting portion 22a and a pair of fixing portions 22b located on both sides of the mounting portion 22a in the vehicle longitudinal direction X. The mounting portion 22a is used to mount the sleeve 31 that houses the electric rotating unit 13 and the rotating support shaft 24. The pair of fixing portions 22b are fastened to the waistline reinforcement member 21 by bolts 28.

[0071] Furthermore, in this embodiment, such as Figures 9-12 As shown, the wiring harness 25 extends from the space 20 inside the side door 1 to the rearview mirror body 11 and is electrically connected to the internal machine 37 (such as a mirror adjustment unit) inside the rearview mirror body 11.

[0072] Specifically, such as Figures 11-12As shown, the waistline reinforcement 21 has a first opening 21a at a position opposite to the mounting portion 22a of the support member 22. Furthermore, the sleeve 31 of the electric rotation unit 13 has a second opening 31a at a position opposite to the first opening 21a. In addition, the rotation shaft 24 of this embodiment is a hollow cylindrical shape, and a third opening 24a is formed on its circumferential surface at a position opposite to the second opening 31a. Therefore, the wiring harness 25 extends from the inside of the side door 1 through the first opening 21a of the waistline reinforcement 21, the second opening 31a of the sleeve 31, and the third opening 24a of the rotation shaft 24 into the interior of the rotation shaft 24 (see reference). Figure 11 The wiring harness 25 extends upward through the interior of the rotating support shaft 24 (part 25a). Furthermore, the wiring harness 25 extends through the interior of the rotating support shaft 24 and the mirror mount 12 to the interior machine 37 inside the rearview mirror body 11, and is electrically connected to the interior machine 37.

[0073] Furthermore, in the rearview mirror device of this embodiment, the mounting portion 22a of the support member 22 is semi-cylindrical in shape. Therefore, even if the wiring harness 25 is laid as described above, the wiring harness 25 will not interfere with the mounting portion 22a, and the sleeve 31 can be inserted into the mounting portion 22a of the support member from above.

[0074] The cover component 27 covers the gap between the through hole 26 and the rotating support shaft 24 from the outside of the vehicle. Specifically, as... Figures 9-12 As shown, the sleeve 31 housing the electric rotating unit 13 with the rotating shaft 24 and the mounting portion 22a of the support member 22 covering the sleeve 31 are exposed to the outside of the vehicle through the through hole 26 of the door panel 3. On the lower side of the base end 12a of the mirror mount 12, the cover member 27 covers the sleeve 31 housing the rotating shaft 24 and the mounting portion 22a from the outside of the vehicle, and covers the gap between the through hole 26 and the mounting portion 22a.

[0075] In addition, such as Figure 13 As shown, in order to improve visibility from inside the cabin, in this embodiment, when the rearview mirror body 11 is in the mirror usage position P1, in a top view, the inner surface 11b of the rearview mirror body 11 facing the side door 1 is inclined outwards (i.e., inclined away from the side door 1) relative to an imaginary line L1 that is orthogonal to the surface of the mirror 14 and passes through the inner end 11a of the rearview mirror body 11 on the side door 1. That is, the inner surface 11b of the rearview mirror body 11 extends outwards along a line L2 that is inclined towards the outside of the vehicle, with the inner end 11a of the rearview mirror body 11 as the starting point, relative to the imaginary line L1. In other words, Figure 13In the top view, when the rearview mirror body 11 is in the mirror use position P1, the thickness of the rearview mirror body 11 in the front-rear direction X decreases (becomes tapered) as it moves from the middle position of the rearview mirror body 11 in the vehicle width direction Y toward the inner end 11a on the side of the upper door 1 in the vehicle width direction Y.

[0076] Based on the shape of the rearview mirror body 11 as described above, such as Figure 14 As shown, the inner side 11b of the rearview mirror body 11 no longer obstructs the view from the cockpit. As a result, the space S1 in front of the rearview mirror body 11, that is, the space S1 enclosed by the inner end 11a of the rearview mirror body 11, the A pillar 4 and the waistline BL, can be ensured to have a wide field of view, thus improving visibility.

[0077] Furthermore, for reference, in the comparative examples of the present invention, such as Figure 15 As shown in the rearview mirror 50, in the device that houses the electric rotating unit (not shown) in the rearview mirror body 51, the front-to-back width of the rearview mirror body 51 increases. Therefore, as the front-to-back width increases, the inner side 51b of the rearview mirror body 51 will be visible in the field of view from inside the cockpit. Thus, it can be seen that the field of view in the space S2 in front of the rearview mirror body 51, that is, the space S2 enclosed by the inner end 51a of the rearview mirror body 51, the A pillar 4, and the waistline BL, becomes narrower, and visibility decreases.

[0078] (Explanation of the control system)

[0079] Next, the control system in the rearview mirror device of this embodiment will be described.

[0080] like Figure 7 and Figure 16 As shown, the control system of the rearview mirror device in this embodiment includes three components: an electric rotation unit 13, a control unit 40, and a user operation detection unit 42.

[0081] like Figure 16 As shown, the electric rotation unit 13 includes a motor 32 and a rotation sensor 38, which serves as a rotation detection unit for detecting the rotation speed of the motor 32, as described above. In this embodiment, the rotation sensor 38 is included in the electric rotation unit 13, but the present invention is not limited thereto; it can be included in any rearview mirror device.

[0082] The control unit 40 includes a control unit 41 for controlling the electric rotation unit 13 (specifically, the motor 32) and a storage unit 45.

[0083] The user operation detection unit 42 includes a retraction switch 43 and a mirror adjustment switch 44. The retraction switch 43 selects either the retraction or unfolding action of the rearview mirror 2 (rearview mirror body 11 and mirror mount 12), and outputs a retraction signal to initiate the retraction action or an unfolding signal to initiate the unfolding action to the control unit 41. The mirror adjustment switch 44 is a switch for horizontal mirror adjustment, which allows the user to finely adjust the angle of the mirror 14 from a certain mirror usage position P1 (setting position). It outputs a mirror adjustment signal for adjusting the mirror to the control unit 41. The mirror adjustment switch 44 can be any structure that allows fine adjustment of the tilt angle of the mirror 14 relative to the certain mirror usage position P1 (setting position) in a top view, and outputs a mirror adjustment signal (e.g., a signal with a scale of 0.1 to 1 degree) to the control unit 41 to indicate that the angle is changed by a certain angle each time it is turned towards the front and rear of the vehicle. For example, it can be a dial type, button type, or slide type switch.

[0084] When a storage signal is input from the storage switch 43, the control unit 41 controls the electric rotation unit 13 to rotate the rearview mirror 2 (rearview mirror body 11 and mirror base 12) from the mirror use position P1 to the storage position P2. Furthermore, when an unfolding signal is input from the storage switch 43, the control unit 41 controls the electric rotation unit 13 to rotate the rearview mirror 2 from the storage position P2 to the mirror use position P1. Additionally, when a mirror adjustment signal is input from the mirror adjustment switch 44, the control unit 41 controls the electric rotation unit 13 to rotate the rearview mirror 2 (rearview mirror body 11 and mirror base 12) within a small range relative to the mirror use position P1, thereby changing the angle of the mirror 14.

[0085] In this invention, "minor range" refers to a range that is sufficiently small than the range of rotation angles of the rearview mirror 2 from the storage position P2 to the mirror use position P1 (for example, 1 to 20% of the entire range of rotation angles between the aforementioned positions P1 and P2). Preferably, the minor range is a range within which the rearview mirror body 11 and the mirror mount 12 can rotate ±5 degrees with respect to the mirror use position P1 (setting position).

[0086] The storage unit 45 stores position information related to the position of the rearview mirror 2. Specifically, when a mirror adjustment signal is input to the control unit 41, the electric rotation unit 13 rotates the rearview mirror 2 within a small range to perform mirror adjustment, and the storage unit 45 stores position information related to the position of the rearview mirror 2 after mirror adjustment based on the rotation speed of the motor 32 at that time. In addition, the position information is not limited to the rotation speed of the motor 32, but can also be based on other parameters, such as the output shaft 35 of the electric rotation unit 13, the rotation angle of the rotation support shaft 24, etc.

[0087] (Explanation of the control flow diagram)

[0088] The following is for reference Figure 17 The control flowchart describes the various action steps of storing and unfolding the mirror, adjusting the mirror surface, and maintaining the mirror angle in the rearview mirror device of this embodiment.

[0089] <Storage Mirror>

[0090] First, with the rearview mirror 2 (rearview mirror body 11 and mirror mount 12) in the rearview mirror use position P1, the control unit 41 determines whether a storage operation signal from the storage switch 43 has been detected (step S1).

[0091] When a storage operation signal is detected, the following steps S2 to S10 related to "storing the mirror" are performed in order to perform normal mirror storage and unfolding. First, in step S2, the control unit 41 causes the storage unit 45 to save the mirror position information of the rotation sensor 38 (specifically, position information related to the position of the rearview mirror 2 based on the rotation sensor 38 detecting the rotation speed of the motor 32). Next, in step S3, the control unit 41 starts to energize the motor 32 in the storage direction; energizing continues until the motor 32 is detected to be locked at the storage position P2 (step S4); after the motor 32 is detected to be locked, energizing the motor 32 is stopped (step S5). As a result, the rearview mirror 2 is rotated to the storage position P2 and stopped by the electric rotation unit 13.

[0092] Subsequently, when the control unit 41 detects the unfolding signal from the storage switch 43 (if yes in step S6), the control unit 41 starts to energize the motor 32 in the unfolding direction (step S7), and detects the mirror position by detecting the rotation speed of the motor 32 through the rotation speed sensor 38 (step S8). When the mirror position matches the position stored in the storage unit 45 (if yes in step S9), the control unit 41 stops energizing the motor 32 (step S10), and returns to step S1 while maintaining the unfolded state of the rearview mirror 2. Thus, the rearview mirror 2 can be rotated and stopped to a position that matches the mirror position information stored in the storage unit 45 by the electric rotation unit 13.

[0093] <Mirror Adjustment>

[0094] On the other hand, if the control unit 41 does not detect a storage operation signal in step S1 (if step S1 is negative), it proceeds to step S11 to determine whether a mirror adjustment signal caused by the operation of the mirror adjustment switch (adjustment SW) 44 is detected. If a mirror adjustment signal is detected (if step S11 is positive), the following steps S12 to S17 related to "mirror adjustment" are performed in order to adjust the mirror of the rearview mirror 2. First, in step S12, the control unit 41 starts to power on the motor 32. In step S13, the rotation speed of the motor 32 is detected by the rotation speed sensor 38 to detect the mirror position. In step S14, the mirror position is continuously detected until the operation of the mirror adjustment switch 44 ends. When the operation of the mirror adjustment switch 44 ends (if step S14 is positive), the control unit 41 stops powering on the motor 32 (step S15). Thus, the mirror of the rearview mirror 2 is adjusted to the mirror position desired by the user by the electric rotation unit 13 and then stopped. Next, in step S16, the position of the mirror is detected by the rotation sensor 38. In step S17, the mirror position information of the rotation sensor 38 is saved in the storage unit 45 in the same way as in step S2. Then, the rearview mirror 2 is returned to the unfolded state after the mirror surface is adjusted.

[0095] <Maintain the mirror angle>

[0096] On the other hand, if no mirror adjustment signal is detected from the mirror adjustment switch 44 in step S11 (if step S11 is negative), the following steps S21 to S26 are performed to maintain the angle of the rearview mirror 2. First, in step S21, the mirror position is detected by the rotation sensor 38. Next, the control unit 41 determines whether the rearview mirror 2 has moved from the position saved in the storage unit 45. If it has not moved, it returns to step S1; if it has moved, it proceeds to step S23. To perform active control, the motor 32 is energized to move the rearview mirror 2 in the direction of returning to the saved position. Then, the rotation sensor 38 detects the mirror position. In step S25, it is determined whether the rearview mirror 2 is consistent with the saved position. If it is inconsistent, steps S23 to S24 are repeated. If it is consistent, after stopping the energization of the motor 32 in step S26, the rearview mirror 2 returns to step S1 with the angle of the mirror position saved in the storage unit 45 maintained.

[0097] (Instructions for mirror adjustment)

[0098] In this embodiment, in order to adjust the mirror surface of the rearview mirror 2, the control unit 41 performs the above-described... Figure 17 Steps S11 to S17, thus... Figure 18 As shown, the rearview mirror 2 (rearview mirror body 11 and mirror base 12) can be rotated horizontally around the rotation pivot 24 within a small range of ±θ degrees before and after the baseline A0 with the mirror usage position P1 (setting position) as the reference, thereby changing the angle of the mirror 14.

[0099] Through the above mirror adjustments, such as Figure 19 As shown, the field of vision in the rearview mirrors on the driver's side and the passenger side changes when the vehicle is parked. Specifically, the field of vision corresponding to the mirror's usage position P1 (setting position) changes. Figure 19 Compared to the field of vision at a 0-degree tilt, tilting forward at 4 degrees and 8 degrees (i.e., tilting the rearview mirror 2 4 and 8 degrees from its set position towards the front of the vehicle) provides a wider rearward field of vision extending far beyond the vehicle's width. Conversely, tilting backward at 4 degrees (towards the rear of the vehicle) provides a closer rearward field of vision to the rear of the vehicle. Therefore, by adjusting the mirror, the driver can obtain the desired range of rearward vision, such as a wide rearward field of vision extending far beyond the vehicle's width while driving, and a closer rearward field of vision to the rear of the vehicle when reversing into a parking space.

[0100] (Features of this embodiment) (1)

[0102] The rearview mirror device of this embodiment is a rearview mirror device on the side door 1 of a vehicle. The rearview mirror device includes: a rearview mirror body 11 having a mirror 14 for obtaining a rear view of the vehicle; a mirror mount 12 having a front end portion 12b fixed to the rearview mirror body 11 and a base end portion 12a away from the front end portion 12b; a rotation support shaft 24 connected to the base end portion 12a of the mirror mount 12 and supporting the rearview mirror body 11 and the mirror mount 12 so that they can freely rotate between a mirror use position P1 and a storage position P2 located inside the vehicle width direction of the mirror use position P1, which can be seen by the naked eye from the cabin; an electric rotation unit 13 that rotates the rearview mirror body 11 and the mirror mount 12 about the axis of the rotation support shaft 24 so that they rotate between the mirror use position P1 and the storage position P2; and a control unit 41 that controls the electric rotation unit 13.

[0103] In this rearview mirror device, an electric rotating unit 13 is disposed on the side door 1. Furthermore, when a storage operation signal is input to initiate the storage action, the control unit 41 controls the electric rotating unit 13 to rotate the rearview mirror body 11 and the mirror base 12 from the mirror use position P1 to the storage position P2. When an unfolding operation signal is input to initiate the unfolding action, the control unit 41 controls the electric rotating unit 13 to rotate the rearview mirror body 11 and the mirror base 12 from the storage position P2 to the mirror use position P1. In addition, when a mirror adjustment signal is input to adjust the mirror surface, the control unit 41 controls the electric rotating unit 13 to rotate the rearview mirror body 11 and the mirror base 12 within a small range based on the mirror use position P1, thereby changing the angle of the mirror 14.

[0104] According to the above solution, in the rearview mirror assembly including a rearview mirror body 11 with a mirror 14 mounted thereon and a mirror mount 12 fixed to the front end 12b of the rearview mirror body 11, the electric rotation unit 13 rotates the mirror mount 12, along with the rearview mirror body 11, from the mirror use position P1 to the storage position P2. Therefore, when the rearview mirror body 11 and the mirror mount 12 are rotated to the storage position P2, the amount of protrusion of the rearview mirror body 11 and the mirror mount 12 from the side of the side door 1 in the vehicle width direction Y can be reduced, thus minimizing the vehicle width dimension.

[0105] Furthermore, in this rearview mirror device, a heavy electric rotating unit 13 is installed inside the side door 1. Therefore, when the vehicle is in motion, the input from the road surface (i.e., the vibration or external force caused by the unevenness of the road surface, mainly in the vertical Z direction) will reduce the vertical Z torque generated by the rearview mirror, thus suppressing the vibration of the mirror.

[0106] Furthermore, since the electric rotation unit 13 is provided in the side door 1, compared with the conventional rearview mirror device in which the electric rotation unit 13 is housed in the rearview mirror body 11, the front-to-back width of the rearview mirror body 11 can be reduced, thereby improving visibility from the cockpit.

[0107] Furthermore, when a mirror adjustment signal is input, the control unit 41 controls the electric rotation unit 13 to rotate the rearview mirror body 11 and the mirror mount 12 within a small range based on the mirror's usage position P1, thereby changing the angle of the mirror 14. As a result, the mirror can be adjusted in the horizontal direction by using the electric rotation unit 13, simplifying the mirror adjustment unit that was previously installed on the rearview mirror body 11. (2)

[0109] In the rearview mirror device of this embodiment, the electric rotating unit 13 is disposed inside the side door 1, so the electric rotating unit 13 can be protected from the influence of foreign objects outside the vehicle by the door panel 3 provided on the outer side of the side door 1. Alternatively, the electric rotating unit 13 can also be disposed outside the side door 1, in which case a large cover component or the like is required to protect the electric rotating unit 13. (3)

[0111] In the rearview mirror device according to this embodiment, the rearview mirror device further includes a storage unit 45 (see reference 45). Figure 16 It stores position information related to the position of the rearview mirror body 11 and mirror base 12 after mirror adjustment when the mirror adjustment signal is input to the control unit 41.

[0112] With the rearview mirror body 11 and mirror base 12 in the stowed position, when an unfolding signal is input, the control unit 41 controls the electric rotation unit 13 to rotate the rearview mirror body 11 and mirror base 12 from the stowed position to the mirror usage position, thereby positioning the rearview mirror body 11 and mirror base 12 at the position corresponding to the position information stored in the storage unit 45 (see reference). Figure 17 Steps S6 to S10).

[0113] According to the above scheme, the position information related to the position of the rearview mirror body 11 and mirror base 12 when the mirror surface has been adjusted is pre-stored in the storage unit 45. When the next unfolding operation signal is input, the control unit 41 controls the electric rotation unit 13 to position the rearview mirror body 11 and mirror base 12 in the position corresponding to the position information stored in the storage unit 45. As a result, the user is spared the effort of adjusting the mirror surface every time the unfolding operation is performed, thus improving convenience. (4)

[0115] In the rearview mirror device according to this embodiment, when the positions of the rearview mirror body 11 and the mirror mount 12 are changed without being driven by the electric rotation unit 13, the control unit 41 controls the electric rotation unit 13 to adjust the rearview mirror body 11 and the mirror mount 12 back to the positions corresponding to the position information stored in the storage unit 45 (see reference). Figure 16 Steps S22 to S26).

[0116] According to the above scheme, when the positions of the rearview mirror body 11 and the mirror mount 12 are not changed due to the driving of the electric rotation unit 13, the control unit 41 controls the electric rotation unit 13 to adjust the rearview mirror body 11 and the mirror mount 12 back to the positions corresponding to the position information stored in the storage unit 45. Therefore, when an external force acts on the rearview mirror body 11, causing it to rotate unexpectedly, the rearview mirror body 11 can be automatically restored to its previous position before rotation. In this way, unlike conventional electric rotation units 13, there is no need to increase rotational resistance to resist the external force causing the rearview mirror body 11 to rotate, thus reducing the rotational resistance of the electric rotation unit 13. (5)

[0118] In the rearview mirror device according to this embodiment, the "minimum range" is the range within which the rearview mirror body 11 and the mirror mount 12 can be rotated ±5 degrees with respect to the mirror's usage position P1. According to the above solution, the "minimum range" is the range described above, within which the driver can adjust the mirror surface to view the vehicle body through the mirror 14 when parking and to view the lane lines through the mirror 14 when driving. (6)

[0120] In the rearview mirror device according to this embodiment, the rotating support shaft 24 is fixed to the base end 12a of the mirror base 12 and is driven by the rotational force from the electric rotating unit 13, so that it can rotate together with the mirror base 12 around the axis of the rotating support shaft 24. According to the above solution, the mirror base 12 can be rotated simply by rotating the rotating support shaft 24 through the rotational driving force from the electric rotating unit 13, and the rearview mirror structure is simple. (7)

[0122] In the rearview mirror device of this embodiment, the electric rotation unit 13 (specifically, its main components are a motor 32, a reducer 33, a torque limiter 34, an output shaft 35, and a rotation speed sensor 38) is arranged on the axis of the rotation support shaft 24. According to the above scheme, since the electric rotation unit 13 is arranged on the axis of the rotation support shaft 24, a simple and compact power transmission system structure for transmitting power from the electric rotation unit 13 to the rotation support shaft 24 can be constructed. Therefore, the electric rotation unit 13 can be installed within the limited space of the side door 1. (8)

[0124] In the rearview mirror device of this embodiment, a through hole 26 is formed in the door panel 3 constituting the outer side of the side door 1 for the rotation pivot 24 to pass through. The rearview mirror device also includes a cover member 27 that covers the gap between the through hole 26 and the rotation pivot 24 from the outside of the vehicle. According to the above solution, the cover member 27 covers the gap between the through hole 26 and the rotation pivot 24 in the door panel 3 from the outside of the vehicle, thereby improving the vehicle's aesthetics and preventing water from seeping into the door panel 3 through the gap. (9)

[0126] In the rearview mirror device of this embodiment, the electric rotating unit 13 is fixed to the waistline reinforcement member 21, which is a skeleton member constituting the frame of the side door 1 and is provided inside the side door 1. According to the above solution, the electric rotating unit 13 is fixed to the waistline reinforcement member 21, which is a skeleton member constituting the frame of the side door 1, thereby improving the support rigidity of the electric rotating unit 13. (10)

[0128] In the rearview mirror device of this embodiment, the frame member is a waistline reinforcement 21 that extends along the waistline BL of the lower edge of the side door window in the vehicle longitudinal direction X. According to the above solution, by fixing the electric rotating unit 13 to the waistline reinforcement 21 commonly used in conventional door devices, the above-mentioned rearview mirror device can be widely used in conventional door devices. (11)

[0130] In the rearview mirror device of this embodiment, the waistline reinforcement 21 is made of extruded aluminum. According to the above solution, the waistline reinforcement 21 is made of extruded aluminum, thus ensuring both the support rigidity of the electric rotation unit 13 and the lightweight of the vehicle. (12)

[0132] In the rearview mirror device of this embodiment, such as Figure 13 As shown, in the top view, when the rearview mirror body 11 is in the mirror use position P1, the inner side 11b of the rearview mirror body 11 facing the side door 1 is inclined outward relative to the imaginary line L1 that is orthogonal to the surface of the mirror 14 and passes through the inner end 11a of the rearview mirror body 11.

[0133] According to the above solution, when the rearview mirror body 11 is in the mirror usage position P1, the inner side surface 11b of the rearview mirror body 11 is tilted outward relative to the imaginary line L1 orthogonal to the mirror surface, so that the inner side surface 11b of the rearview mirror body 11 no longer obstructs the view from inside the cabin. In this way, the visibility from inside the cabin can be maximized, further improving visibility. (13)

[0135] In the rearview mirror device of this embodiment, such as Figure 13 As shown, in the top view, when the rearview mirror body 11 is in the mirror use position P1, the thickness of the rearview mirror body 11 in the front-rear direction X decreases as it moves from the middle position in the vehicle width direction Y of the rearview mirror body 11 toward the inner end 11a on the side of the upper door 1 in the vehicle width direction Y.

[0136] According to the above solution, when the rearview mirror body 11 is in the mirror usage position P1, the thickness of the rearview mirror body 11 in the longitudinal direction X decreases from the middle position in the vehicle width direction Y towards the inner end 11a in the vehicle width direction Y. Therefore, the inner side 11b of the rearview mirror body 11 no longer obstructs the field of vision when looking from the cabin. In this way, the visibility when looking from the cabin can be maximized, further improving visibility.

[0137] (Modified example)

[0138] (A)

[0139] The rearview mirror device of the above embodiment has a structure in which the rotating support shaft 24 is configured in an upright state, and can perform minor mirror adjustments in the horizontal direction, but the present invention is not limited thereto.

[0140] A variation of the present invention is provided to enable minute mirror adjustments not only in the horizontal direction but also in the vertical direction, such as... Figure 20 As shown in (a) and (b), the pivot 24 can be configured to tilt θ2 degrees toward the front of the vehicle X1 as it moves upward Z1 (forward tilt), and tilt θ3 degrees toward the outer side of the vehicle width Y1 as it extends upward Z (outward tilt).

[0141] According to the above scheme, by rotating only the rearview mirror body 11 and the mirror mount 12 around the axis of the rotation support 24, minute mirror adjustments in both the horizontal and vertical directions Z can be performed simultaneously. That is, the vertical mirror adjustment can be minimized. Moreover, the vertical adjustment range Z during mirror adjustment can be reduced, thereby reducing the range of motion of the mirror 14 and contributing to the thinning of the rearview mirror body 11.

[0142] like Figure 20 As shown in the variations of (a) and (b), by tilting the pivot 24 forward and outward, the mirror surface can be adjusted in the vertical direction Z by simply rotating the rearview mirror 2. Therefore, by simply rotating the rearview mirror 2 from a certain mirror usage position P1 (setting position) towards the front of the vehicle, the lower position Z2 can be included in the rear view.

[0143] For example, the above Figure 20 The rearview mirror 2 of the modified examples (a) and (b) is applied to Figure 21 When in the car shown, Figure 21 In the mirror, the lower edge of the rear view at position P1 (setting position) is line L1, while at the forward rotation position, the lower edge of the rear view drops to line L2, thus allowing the area further down to Z2 to be included in the rear view. Furthermore, Figure 22 In the tilted rearview mirror shown (tilt forward + tilt outward), it can be seen that the rearward field of view at the forward-turned position is more downward than the rearward field of view at the mirror's usage position P1 (setting position). Therefore, by rotating the rearview mirror 2, the vertical field of view Z can be changed, allowing the vertical mirror surface to be adjusted to a minimum.

[0144] In contrast, such as Figures 1-7 When the rearview mirror 2 described in the above embodiment is upright (i.e., neither tilted forward nor outward) using the rotating support 24, in Figure 21 In the diagram, line L3, representing the lower edge of the rear view at the mirror's usage position P1 (setting position), and line L4, representing the lower edge of the rear view at the forward rotation position, are at the same position, indicating that vertical mirror adjustment is not possible. Furthermore, see... Figure 22 When the rearview mirror shown is tilt-free (without forward tilt or outward tilt), the rear view at the mirror's position P1 (setting position) is almost the same as the rear view at the forward-turned position, indicating that vertical mirror adjustment is not possible.

[0145] By using the above Figures 21-22 The verification results show that, as mentioned above Figure 20 Similar to the variations in (a) and (b), the structure in which the rotating support shaft 24 is tilted forward and outward can simultaneously achieve minute mirror adjustments in both the horizontal and vertical directions Z.

[0146] (B)

[0147] The mirror of the present invention encompasses various methods, as long as it is used to obtain a rear view of a vehicle. For example, in addition to the optical mirror 14 in the above embodiment that reflects light from behind the vehicle to obtain a rear view, the concept of the mirror of the present invention also includes a so-called electronic mirror that has a television camera in the rearview mirror body 11 and can obtain a rear view through the television camera.
