Description

Technical Field

[0001] This invention relates to a vehicle interior rearview mirror, and more specifically to an electrically adjustable vehicle interior rearview mirror. Background Technology

[0002] The rearview mirror is a crucial safety accessory for drivers to obtain a view of what's behind the vehicle, and its adjustment method directly affects driving experience and safety. Currently, most traditional rearview mirrors use a ball joint structure between the mirror body and the mounting bracket to achieve omnidirectional adjustment, which typically requires manual operation. While this structure is simple and inexpensive, it has the following shortcomings in practical use: Manual adjustment is difficult to control in terms of precision. During the adjustment process, drivers often cannot adjust the rearview mirror to the ideal angle in one go, and it is easy to over-adjust or under-adjust. They need to lean forward repeatedly to make fine adjustments, which is cumbersome and affects the driver's concentration. Furthermore, the existing ball joint connection method is difficult to adapt to electric drive. Summary of the Invention

[0003] To address the above problems, the present invention provides the following technical solution: An electrically adjustable rearview mirror for vehicles includes: a fixed bracket for mounting on a vehicle body; a connector movably connected to the fixed bracket; a mirror body movably connected to the connector; a first drive mechanism connected to the connector and the fixed bracket for driving the connector to rotate around the fixed bracket along the width direction of the mirror body; and a second drive mechanism disposed between the mirror body and the connector for driving the mirror body to rotate around the connector along its length direction.

[0004] The present invention is further configured to include a first angle monitoring component for monitoring and recording the rotation angle of the connector; and a second angle monitoring component for monitoring and recording the rotation angle of the mirror body.

[0005] The present invention is further configured such that: the connector is rotatably connected to the fixed bracket along the width direction of the mirror body; one end of the connector is connected to a mounting bracket, and the first driving mechanism is mounted on the mounting bracket.

[0006] The present invention is further configured such that: the first driving mechanism includes a first power source, a push rod, and a connecting rod; the push rod is connected to the first power source; the two ends of the connecting rod are respectively rotatably connected to the fixed bracket and the push rod, and the rotation axis is set along the width direction of the lens body; the push rod is driven to translate along the length direction of the lens body by the first power source, thereby driving the first driving mechanism and the connecting member to rotate along the width direction of the lens body.

[0007] The present invention is further configured such that: the second driving mechanism includes a second power source disposed on the lens body, the second power source having an output shaft connected to the end of the connector away from the mounting bracket, the output shaft rotating along the length direction of the lens body and being limited by the connector along the rotation direction, thereby driving the lens body to rotate around the connector along its length direction by rotating the output shaft of the second power source.

[0008] The present invention is further configured such that: the output shaft is connected to the connecting member via a coupling; the mirror body is provided with a first bearing seat, the end of the connecting member is rotatably connected to the first bearing seat via a bearing, the mirror body is provided with a second bearing seat, and the end of the mounting bracket is rotatably connected to the second bearing seat via a bearing.

[0009] The present invention is further configured such that: the first angle monitoring component includes a grating fixed on one of the mounting bracket and the push rod, and a light source plate and a stripe hole cover fixed on the other of the two. The light source plate emits narrow stripe light to the grating through the stripe hole cover. The current position of the push rod is obtained according to the number of slits passing through the grating, thereby obtaining the angle of rotation of the connector along the width direction of the mirror body. The first angle monitoring component records the current position information.

[0010] The present invention is further configured such that: the second angle monitoring component includes a Hall magnet fixed on one of the mirror body and the connector, and a Hall plate fixed on the other of the two, the Hall magnet and the Hall plate being arranged opposite to each other and maintaining a distance, when the mirror body rotates relative to the connector, the Hall plate detects the change in the magnetic field generated by the Hall magnet, thereby obtaining the angle of rotation of the mirror body along its length direction, and the second angle monitoring component records the current position information.

[0011] The present invention is further configured such that: the Hall magnet is coaxially fixed on the rotating shaft of the connector in the length direction of the mirror body, the mirror body is provided with a fixing member, and the Hall plate is fixed on the fixing member and perpendicular to the Hall magnet.

[0012] The present invention is further configured to include a control unit, wherein the first driving mechanism, the second driving mechanism, the first angle monitoring component, and the second angle monitoring component are all electrically connected to the control unit, and the control unit controls the first driving mechanism and / or the second driving mechanism to operate according to the monitored angle information, thereby realizing automatic adjustment or reset of the mirror angle.

[0013] Compared with the prior art, the present invention has at least the following advantages: 1. The dual-drive mechanism enables electric rotation adjustment of the mirror body along the width and length directions, replacing the traditional manual adjustment method. This solves the problems of difficult control of manual adjustment force, easy over-adjustment / under-adjustment, and cumbersome operation. Through the compact integration and motion decoupling of the connector and the dual-drive mechanism, the two degrees of freedom of motion, rotation in the width direction and rotation in the length direction, are independent and do not interfere with each other. This avoids the problem of mutual restraint of angles when adjusting universally in the traditional ball joint structure, and realizes decoupled control of bidirectional adjustment. This provides stable mechanical motion support for subsequent two-dimensional precise adjustment and angle monitoring.

[0014] 2. By pairing with corresponding angle monitoring components, the rotation angle of the mirror body in two directions is monitored and recorded in real time, so as to achieve precise control of the adjustment angle, provide a data basis for angle reset, greatly improve the convenience, accuracy and user experience of the rearview mirror adjustment, and reduce the safety hazards of manual adjustment that distract the driver's attention.

[0015] 3. The first angle monitoring component and the second angle monitoring component are respectively adopted by the grating component and the Hall component, which can monitor the rotation angle of the mirror in two directions in real time and accurately, and record the current adjustment position. When the mirror angle changes due to accidental touch or change of driver, it can be automatically reset to the recorded angle through the control unit, avoiding the tediousness of repeated manual adjustment and significantly improving the convenience of use.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] like Figure 1 and Figure 4 As shown, an electrically adjustable rearview mirror includes a fixed bracket 6, a mirror body 1, a first drive mechanism 3, a second drive mechanism 7, a first angle monitoring component 8, a second angle monitoring component 9, a rear cover 4, a dust cover 5, and a control unit. The fixed bracket 6 serves as the mounting reference for the entire rearview mirror. The mirror body 1 is the main support for the field of vision. The first drive mechanism 3 and the second drive mechanism 7 form a dual drive system, enabling independent rotation adjustment of the mirror body 1 in both width and length directions. The first angle monitoring component 8 and the second angle monitoring component 9 form a dual monitoring system, respectively collecting rotation angle data in both directions. The control unit forms a closed-loop control core, achieving intelligent control of the entire process of adjustment, monitoring, memory, and reset. The rear cover 4 and the dust cover 5 form a protective and aesthetically pleasing structure, ensuring the product's lifespan and appearance.

[0020] The mounting bracket 6 is the core load-bearing component connecting the rearview mirror to the vehicle body. It is used to install the entire rearview mirror on the windshield or roof of the vehicle body and has an installation interface for connecting to the vehicle body. The lower end of the mounting bracket 6 extends downward into the internal cavity of the rear shell 4, forming a hinged engagement with the connector 2, providing a fixed frame support for the rotation and adjustment of the mirror body 1.

[0021] The lens body 1 includes a lens 101 and a transition plate 102. The rear side of the lens 101 is rigidly fixed to the transition plate 102 by means of adhesive backing, snap-fit, or bolt fastening, ensuring that the power of the drive mechanism can be transmitted to the lens body 1 without loss. The transition plate 102, as the core connecting component between the lens body 1 and the drive mechanism, also bears the load-bearing function of the second drive mechanism 7 and is the core carrier of the power input of the lens body 1.

[0022] The rear shell 4 is completely covered on the outside of the transition plate 102, the first drive mechanism 3, and the second drive mechanism 7. The front edge of the rear shell 4 is fastened to the lens mounting seat of the mirror body 1 or the edge of the transition plate 102 by a sealing buckle to form a closed internal mounting cavity. All transmission components and electrical components are housed in this closed cavity, which can effectively isolate dust and moisture from entering the interior during vehicle operation and avoid problems such as wear, short circuit, and corrosion of components.

[0023] The dust cover 5 is made of aging-resistant, highly elastic flexible rubber material and is used to cover the gap between the fixed bracket 6 and the rear shell 4. On the one hand, it can further improve the dustproof and waterproof performance, preventing impurities from entering the internal cavity through the gap between the fixed bracket 6 and the rear shell 4; on the other hand, the flexible material of the dust cover 5 can adapt to the full stroke of the mirror body 1 through its own elastic deformation when the mirror body 1 is adjusted in both directions, without interfering with the rotation of the mirror body 1. At the same time, it can also cover the internal transmission structure and improve the overall appearance of the product.

[0024] The connector 2 is rotatably connected to the fixed bracket 6 along the width direction of the mirror body 1, and the mirror body 1 is then rotatably connected to the connector 2. This connector serves as the core support structure of the entire rearview mirror, indirectly bearing the relative movement between the mirror body 1 and the fixed bracket 6. The connector 2 also includes a mounting bracket 201 fixed to one end, and the first drive mechanism 3 is fixedly mounted on the mounting bracket 201.

[0025] The first drive mechanism 3 includes a first power source 301, a push rod 302, and a connecting rod 303. The mounting bracket 201 is fixed to the connector 2 and serves as the mounting base for the first power source 301, the push rod 302, and the connecting rod 303.

[0026] The first power source 301 is preferably a miniature DC motor, whose output shaft is connected to a transmission mechanism that converts the rotational motion of the motor into the linear reciprocating motion of the push rod 302. For example, the output shaft of the first power source 301 is connected to a lead screw, and the push rod 302 is provided with a nut that cooperates with the lead screw. When the first power source 301 rotates, the lead screw drives the nut to move the push rod 302 in a linear translational motion along the length of the mirror body 1. The push rod 302 is rod-shaped, with one end connected to the first power source 301 and the other end hinged to the connecting rod 303.

[0027] Both ends of the connecting rod 303 are rotatably connected to the fixed bracket 6 and the push rod 302, respectively, and the axis of rotation is set along the width direction of the mirror body 1. When the first power source 301 drives the push rod 302 to translate along the length direction of the mirror body 1, the push rod 302 drives the connecting rod 303 to rotate around its hinge point with the fixed bracket 6. Since the length of the connecting rod 303 is fixed, the translational motion of the push rod 302 is converted into the swing motion of the connecting rod 303, which in turn drives the entire mounting frame 201 to rotate relative to the fixed bracket 6 along the width direction of the mirror body 1 through the connecting piece 2. The forward and reverse rotation of the first power source 301 corresponds to the mirror body 1 rotating to the left or right, and the rotation angle range is preferably ±20°.

[0028] The second drive mechanism 7 includes a second power source 703 and a coupling 704. The second power source 703 is preferably a miniature DC motor, fixedly mounted on the mirror body 1. The output shaft of the second power source 703 is arranged along the length of the mirror body 1. One end of the connecting member 2 has a rotating shaft, and the output shaft is connected to the rotating shaft on the connecting member 2 via the coupling 704. The coupling 704 connects the output shaft of the second power source 703 and the rotating shaft of the connecting member 2, compensating for any possible coaxiality deviation between them, and simultaneously transmitting rotational torque.

[0029] A first bearing seat 701 and a second bearing seat 702 are fixed on the transition plate 102. The shaft at one end of the connector 2 is rotatably connected to the first bearing seat 701 via a bearing, and the end of one side of the mounting bracket 201 is rotatably connected to the second bearing seat 702 via a bearing, thereby realizing the rotatable connection between the connector 2 and the mirror body 1. A certain distance is maintained between the bottom of the connector 1 and the bottom of the mounting bracket 201 and the mirror body 1 to avoid interference during movement.

[0030] The output shaft of the second power source 703 drives the rotating shaft of the connecting member 2 to rotate via the coupling 704. However, the rotation of the connecting member 2 relative to the fixed bracket 6 in the length direction is restricted. Therefore, the second power source 703 actually operates on the principle of reaction force: the second power source 703 is fixed to the mirror body 1. When the output shaft of the second power source 703 rotates and drives the rotating shaft of the connecting member 2, since the rotating shaft of the connecting member 2 rotates relative to the first bearing seat 701, but the connecting member 2 itself does not rotate in the length direction, the reaction force will drive the mirror body 1 to rotate relative to the axis of rotation of the connecting member 2, thereby realizing the rotation of the mirror body 1 in the length direction. The forward and reverse rotation of the second power source 703 corresponds to the upward or downward rotation of the mirror body 1, and the rotation angle range is preferably ±20°.

[0031] The connector 2 is rotatably connected to the fixed bracket 6 along the width direction of the mirror body 1, so that the entire first drive mechanism 3 can rotate relative to the fixed bracket 6 in the width direction of the mirror body 1. At the same time, the mirror body 1 is rotatably connected to the connector 2 and the rotating shaft at the end of the mounting bracket 201 through two bearing seats, so that the mirror body 1 can rotate relative to the connector 1 in the length direction.

[0032] Through the above structural design, two mutually perpendicular rotational degrees of freedom are formed between the connector 2 and the mirror body 1: one is the rotation of the connector 1 relative to the fixed bracket 6 about the width axis (driven by the first drive mechanism 3), and the other is the rotation of the mirror body 1 relative to the connector 2 about the length axis (driven by the second drive mechanism 7). These two rotational degrees of freedom are completely independent mechanically, and their movements do not interfere with each other, achieving decoupling of the two-way adjustment motion. This decoupling structure ensures that adjusting the angle in one direction will not affect the already adjusted angle in the other direction, avoiding the problem of mutual constraint and difficulty in independent control of the two-way angles during universal adjustment in traditional ball joint structures. This provides a stable mechanical motion basis for subsequent precise angle monitoring and automatic reset.

[0033] like Figure 5 and Figure 6 As shown, the first angle monitoring component 8 is used to monitor and record in real time the angle of rotation of the connector 2 along the width direction of the mirror body 1 (the connector 2 rotates synchronously with the mirror body 1 in the width direction, and monitoring the connector 2 is equivalent to monitoring the mirror body 1), providing a data basis for angle reset. The first angle monitoring component 8 includes a grating 801, a light source plate 802, and a stripe aperture cover 803. The grating 801 is fixed on the mounting bracket 201, and parallel slits are arranged at equal intervals on the grating 801. The spacing and number of slits determine the monitoring accuracy. The light source plate 802 is fixed on the push rod 302, and a light-emitting element and a photosensitive receiving element are integrated on the light source plate 802. The stripe aperture cover 803 covers the light source plate 802 and has narrow stripe apertures. The width of the narrow stripe apertures matches the width of the slits in the grating 801 to form a narrow beam of light.

[0034] When the first power source 301 drives the push rod 302 to translate, the light source plate 802 fixed on the push rod 302 moves synchronously. The light emitted by the light-emitting element on the light source plate 802 passes through the narrow stripe holes on the stripe hole cover 803, forming a narrow beam of parallel light, which is projected onto the grating 801. As the push rod 302 moves, the light passes through different slits on the grating 801 in sequence. Each time the light passes through a slit (or is blocked by the structure between the slits), the photosensitive receiving element receives a light pulse signal and converts the light signal into an electrical pulse signal for output.

[0035] By counting the electrical pulse signals, the displacement of the push rod 302 relative to the grating 801 can be accurately calculated. Since there is a definite geometric relationship between the displacement of the push rod 302 and the swing angle of the connecting rod 303, and the swing angle of the connecting rod 303 determines the rotation angle of the connecting member 2 relative to the fixed bracket 6 in the width direction, the current angle of rotation of the mirror body 1 in the width direction can be determined by the displacement.

[0036] The first angle monitoring component 8 transmits the monitored angle information to the control unit in real time, where it is recorded. When it is necessary to reset the mirror body 1 to the previously recorded optimal comfort angle, the control unit controls the first power source 301 to move the push rod 302 to the position corresponding to the recorded displacement, thereby achieving automatic reset of the angle in the width direction.

[0037] like Figure 7 As shown, the second angle monitoring component 9 is used to monitor and record the angle of rotation of the mirror body 1 along its length in real time, providing a data basis for angle reset. The second angle monitoring component 9 includes a Hall magnet 901, a Hall plate 902, and a fixing member 903. The Hall magnet 901 is coaxially fixed to the rotating shaft of the connector 2 along the length of the mirror body 1. In this embodiment, it is fixed to the rotating shaft at one end of the mounting bracket 201. The Hall plate 902 is fixed to the mirror body 1 by the fixing member 903. A Hall element is integrated on the Hall plate 902. The Hall element is arranged opposite to the Hall magnet 901 and maintains a certain gap. The sensing surface of the Hall element is perpendicular to or at a specific angle to the magnetic pole direction of the Hall magnet 901.

[0038] When the second power source 703 drives the transition plate 102 to rotate along the length direction relative to the connecting assembly, a relative rotational motion occurs between the Hall magnet 901, which is fixed to the rotating shaft of the first drive mechanism 3, and the Hall plate 902, which is fixed to the mirror body 1. The direction or intensity of the magnetic field detected by the Hall element changes linearly with the change in the relative rotation angle, and the Hall plate 902 converts the detected magnetic field change into a voltage signal output.

[0039] There is a defined functional relationship (usually sine or cosine) between the voltage signal and the relative rotation angle. Calibration allows the voltage value to be mapped to a specific angle value, thus obtaining the current angle of rotation of the mirror 1 along its length. The second angle monitoring component 9 transmits the monitored angle information to the control unit in real time, where it is recorded. When it is necessary to reset the mirror 1 to the previously recorded optimal comfort angle, the control unit controls the second power source 703 to rotate the mirror 1 to the angle position corresponding to the recorded voltage value, thereby achieving automatic reset of the angle along the length.

[0040] The control unit, as the core of the entire electric adjustment system, is electrically connected to the first power source 301, the second power source 703, the first angle monitoring component 8, and the second angle monitoring component 9, respectively. The control unit can be integrated inside the rearview mirror or located in the vehicle's central control system, communicating via the vehicle's bus.

[0041] The working process of this invention is as follows: When the driver needs to adjust the viewing angle in the width direction (left or right adjustment), the control unit controls the first power source 301 to operate. The first power source 301 drives the push rod 302 to translate along the length direction. The push rod 302 drives the connecting rod 303 to swing, which in turn drives the connecting piece 2 to rotate relative to the fixed bracket 6 in the width direction. The mirror body 1 then rotates to the left or right. At the same time, the grating 801 component in the first angle monitoring component 8 monitors the displacement of the push rod 302 in real time. The control unit calculates the current rotation angle in the width direction based on this and displays or provides feedback in real time.

[0042] When the driver needs to adjust the viewing angle in the length direction (tilt / short adjustment), the control unit controls the second power source 703 to operate. The second power source 703 drives the mirror body 1 to rotate around the axis of rotation through the reaction force, thereby achieving vertical adjustment in the length direction. At the same time, the Hall component in the second angle monitoring component 9 monitors the relative rotation angle between the Hall magnet 901 and the Hall plate 902 in real time. The control unit calculates the current rotation angle in the length direction based on this and displays or provides feedback in real time.

[0043] Once the driver adjusts the mirror 1 to a comfortable position, the current angle can be saved as a memory position. If the angle of the mirror 1 shifts later, the driver only needs to reset it with one button, and the control unit will automatically control the first drive mechanism 3 and the second drive mechanism 7 to accurately restore the mirror 1 to the memory position.

[0044] In summary, this invention provides an electrically adjustable rearview mirror that is compact, precisely adjustable, and has angle memory and reset functions. It effectively solves the technical problems of traditional manual rearview mirrors and has high practical value and market potential.
