- FIG2 shows an adjusting device for adjusting a rearview mirror according to an exemplary embodiment of the present disclosure
- FIG3 shows a possible embodiment of a position feedback module in an adjustment device according to an exemplary embodiment of the present disclosure
- FIG4 shows another possible embodiment of a position feedback module in an adjustment device according to an exemplary embodiment of the present disclosure.

- the rearview mirror assembly of a vehicle generally includes a mirror surface and a bracket.
- the traditional rearview mirror is divided into two parts: bracket adjustment and mirror surface adjustment.
- bracket adjustment part it mainly realizes the function of folding and unfolding the rearview mirror bracket, which requires adjustment through a horizontal motor set on the horizontal plane to control the folding and unfolding of the rearview mirror bracket.
- mirror surface adjustment part the traditional method is to set a horizontal motor and a vertical motor on the horizontal plane and the vertical plane respectively for motion control, so as to adjust the rotation and pitch of the mirror surface respectively.
- this rearview mirror requires a total of three motors, which is not only complex in structure and high in cost, but also difficult to achieve miniaturization of the rearview mirror assembly.
- the traditional solution also proposes a frameless rearview mirror.
- This rearview mirror is small in size, not only has a more beautiful appearance, but also because it brings less wind resistance, it is particularly suitable for electric vehicles and can increase the range of electric vehicles.
- the horizontal motor used for mirror adjustment and the horizontal motor used for bracket adjustment are usually integrated together, and the same motor is used to achieve both functions at the same time.
- the rotation amplitude of the rearview mirror bracket obviously needs to be greater than the rotation amplitude of the mirror adjustment, and the angle control accuracy required for the mirror adjustment is obviously much higher than the angle control accuracy required for the folding and unfolding of the rearview mirror bracket. Therefore, in the design where the horizontal rotation adjustment of the mirror adjustment and the rearview mirror adjustment share the same horizontal rotation motor, when the associated control circuit and feedback circuit are also the same, sharing the same set of horizontal adjustment mechanisms will significantly reduce the angle control accuracy of the mirror adjustment.
- the embodiments of the present disclosure are A rearview mirror adjustment solution. Some exemplary embodiments according to the present disclosure are described below in conjunction with FIGS. 1 to 5 .

- the first input 211 can be input by a user through a button or knob set inside the vehicle (for example, the inside of the door), or it can be input by a user by operating an operation interface set on the screen of the center console.
- the input receiving module 21 can also be used to receive a second input 212 representing the adjustment bracket. Similar to the first input 211, the second input 212 can be input by a user through a button or knob set inside the vehicle, or it can be input by a user by operating an operation interface set on the screen of the center console.
- the input receiving module 21 can also be used to simultaneously receive the first input 211 representing the adjustment of the mirror and the second input 212 representing the adjustment bracket.
- the adjusting device 2 further includes a motor 22.
- the motor 22 can rotate forward and reverse, and is used to drive the mirror surface and the bracket to rotate in both directions.

- the control module 23 can be integrated into the vehicle body controller or can be a separate control module 23 for the rearview mirror. The embodiments do not impose any particular restrictions on this.
- the position feedback module 24 is coupled to the motor 22, and the position feedback module 24 can obtain the amount of rotation of the motor 22.
- the amount of rotation of the motor 22 is associated with the current position of the mirror surface and the bracket of the rearview mirror (i.e., the angle of rotation), and the position feedback module 24 can feedback the position to the control module 23 through a signal.
- the control module 23 can identify the signal from the position feedback module 24, and perform logical judgment based on the signal to determine when the motor 22 stops.
- the control module 23 can control the motor 22 to stop at a predetermined position, so that the rearview mirror 3 can be adjusted to a predetermined angle, thereby adjusting the rearview mirror 3.
- the signal fed back to the control module 23 by the position feedback module 24 can be a voltage signal.
- such a signal can be a resistance signal.
- the signal can also be a current signal, and the specific signal form is not limited by the embodiments of the present disclosure.
- the control module 23 has a certain recognition accuracy, and only signals that meet the corresponding recognition accuracy can be accurately recognized by the control module 23. For example, when the minimum change in the voltage signal that the control module 23 can recognize is 0.05V, if the actual change is 0.50V or 1.00V, the recognition of the change will be accurate. If the actual change is 0.51V or 1.03V, it can only be approximately recognized as 0.50V or 1.00V due to the limitation of accuracy, resulting in the recognition result not being completely accurate. Therefore, when the minimum change to be recognized is 0.05V, only when the amplitude of the voltage change is 0.05V or an integer multiple thereof can it be accurately recognized, and the recognition of other changes is only approximately accurate.
- an existing solution is to improve the recognition accuracy of the control module 23, for example, to improve its recognition accuracy from 0.05V to 0.01V.
- This design can improve the recognition accuracy, the cost is relatively high.
- the embodiment of the present disclosure does not change the recognition accuracy of the control module 23, but focuses on the position feedback module 24.
- the recognition accuracy remains unchanged, by making the physical quantity (such as displacement or angle) of the position feedback module 24 corresponding to the recognition accuracy smaller, it is possible to identify a smaller change in the position feedback module 24, so that the rearview mirror 3 can also be adjusted with higher accuracy.
- the feedback of the position feedback module 24 for the mirror adjustment and the bracket adjustment is different.
- the position feedback module 24 distinguishes the adjustment of the mirror and the bracket, thereby applying different adjustment accuracies to the mirror adjustment and the bracket adjustment, thereby achieving accurate adjustment of the rearview mirror 3 through reasonable accuracy allocation without increasing the cost of the control module 23.
- the position feedback module 24 can output first data to the control module 23.
- the position feedback module 24 will output second data different from the first data to the control module 23. That is, for the same motor rotation angle ⁇ , based on whether it is the first input 211 for mirror adjustment or the second input 212 for bracket adjustment, the position feedback module 24 can output different values, i.e., reflect different adjustment accuracies.
- the position feedback module 24 can take a variety of different specific forms, which will be described in detail below.
- the rearview mirror 3 of the vehicle 1 is in a fully retracted position when it is parked. If the vehicle 1 needs to be driven at this time, the user will operate the knob of the vehicle 1 or the screen on the center console to unfold the bracket and mirror surface of the rearview mirror 3. Since the rearview mirror has just been unfolded from the fully retracted position and is not in the effective working angle range, the user's requirements for the angle adjustment accuracy are not high in the initial adjustment. At this time, the rotation amplitude of the rearview mirror 3 can be larger, so that the rearview mirror 3 can be rotated from the fully retracted position to the effective working angle range more quickly.
- the rotation amplitude of the rearview mirror 3 will become smaller.
- the specially designed position feedback module 24 can distinguish between the rearview mirror bracket adjustment and the mirror adjustment, so that when the user adjusts the rearview mirror 3, the bracket adjustment and the mirror adjustment can have different adjustment precisions. High-precision adjustment of the mirror surface.
- FIG3 shows a feasible embodiment of a position feedback module 24 in an adjustment device according to an exemplary embodiment of the present disclosure.
- the position feedback module 24 includes a sliding rheostat 241.
- the sliding rheostat 241 includes a resistance adjustment area 242 and a slider 243 that can slide on the resistance adjustment area 242.
- the slider 243 can be coupled to the motor 22 so that the rotation of the motor 22 drives the slider 243 to slide on the resistance adjustment area 242.
- the resistance adjustment area 242 includes adjacent first areas S1 and second areas S2.
- the first area S1 and the second area S2 are designed to reflect different resistance values to the control module 23 when the slider 243 slides thereon, so that the control module 23 can have different adjustment accuracies for mirror adjustment and bracket adjustment.
- the first area S1 and the second area S2 may have different resistance densities, for example, the resistance density of the first area S1 is higher than the resistance density of the second area S2, so that when the slider 243 slides the same predetermined distance, different first data and second data can be outputted respectively on the first area S1 and the second area S2, thereby feeding back different voltage changes.
- the slider 243 slides on the first area S1
- due to the higher resistance density of the first area S1 when the slider 243 slides a certain distance D, a larger change of the feedback signal can be generated in the circuit connected to the sliding rheostat 241, and the resistance signal output to the control module 23 can have a higher precision, which corresponds to the mirror adjustment of the rearview mirror.
- first area S1 and the second area S2 may be made of different materials. It should be noted that other solutions can be envisioned to design the first area S1 and the second area S2 to reflect different resistance values when the slider 243 slides thereon, and the embodiments of the present disclosure do not impose any particular limitation on this.
- the resistance adjustment area 242 of the position feedback module 24 is divided according to the bracket adjustment and mirror adjustment of the rearview mirror 3, and position feedback circuits with different precisions are used for different parts, so as to achieve high-precision adjustment of the mirror horizontal direction when the mirror adjustment of the rearview mirror 3 and the bracket adjustment of the rearview mirror share a motor.
- the resistance adjustment area 242 also includes a third area S3, wherein the first area S1 is located between the second area S2 and the third area S3.
- the third area S3 is configured to output third data different from the first data to the control module 23 in response to the slider sliding a predetermined distance on the third area.
- the resistance density of the third area S3 is lower than the resistance density of the first area S1.
- the mirror adjustment that requires precise adjustment is often located in the middle of the adjustment process, while the bracket adjustment with lower precision requirements is located at both ends of the adjustment range (i.e., the early and late stages). Therefore, the first area S1 with higher resistance density is set in the middle and the second area S2 and the third area S3 with lower resistance density are set on both sides, which can correspond well to the adjustment of the rearview mirror, thereby ensuring that a good driving vision is provided for the driver.
- the accuracy ratio of mirror adjustment to bracket adjustment can be adjusted by adjusting the resistance distribution between each area S1, S2, and S3.
- the accuracy of mirror adjustment can be 2.8 times the accuracy of bracket adjustment.
- the ranges of each area S1, S2, and S3 in the resistance adjustment area shown in Figure 3 are only schematic and not restrictive. According to actual needs, the ranges of these areas can be adjusted accordingly. The specific range is not limited by the embodiments of the present disclosure.
- the control module 23 drives the motor 22 to rotate in both directions, thereby driving the rearview mirror surface and the bracket to rotate together.
- the position change of the motor 22 triggers the change in the resistance value of the sliding rheostat 241 in the position feedback module 24.
- the control module 23 can identify the change in the position based on the signal indicating the position of the motor 22 transmitted by the position feedback module 24, and control the motor 22 to stop and prompt the user when necessary.
- FIG. 4 shows another feasible embodiment of the position feedback module 24 in the regulating device according to the exemplary embodiment of the present disclosure.
- the position feedback module 24 includes a signal transmitting unit 245 for transmitting a signal, a signal receiving unit 246 for receiving the signal, and a gear 247 arranged between the signal transmitting unit 245 and the signal receiving unit 246.
- the gear 247 has a plurality of teeth, and the signal transmission between the signal transmitting unit 245 and the signal receiving unit 246 is affected by these teeth.
- the signal transmission path between the signal transmitting unit 245 and the signal receiving unit 246 can be arranged near the rim of the gear 247, so that when the signal is blocked by the teeth of the gear 247, the signal transmission between the signal transmitting unit 245 and the signal receiving unit 246 is interrupted, so that the signal receiving unit 246 cannot receive the signal from the signal transmitting unit 245; or as the gear 247 rotates, when the signal passes through the tooth gap between the teeth of the gear 247, the signal can smoothly reach the signal receiving unit 246.
- the signals received by the signal receiving unit 246 are intermittent signals, and the duty cycle of these signals is affected by the gear tooth size and/or tooth gap size of the gear 247.
- the gear tooth size here may include parameters such as the gear tooth pitch, tooth thickness, tooth height, tooth top height, tooth root height, etc.
- the tooth gap size here may refer to the gap between adjacent gears.
- the gear teeth on the gear 247 are not equidistant.
- the gear 247 may include a first gear segment 2471 and a second gear segment 2472 that are adjacent.
- the tooth gap size of the first gear segment 2471 may be different from the tooth gap size of the second gear segment 2472.
- the first gear segment 2471 has a smaller tooth gap size
- the second gear segment 2472 has a relatively larger tooth gap size.
- the tooth size of the first gear segment 2471 may be different from the tooth size of the second gear segment 2472. According to this configuration, similar to the difference in tooth gap size described above, the difference in gear tooth size will also cause a change in the duty cycle of the signal transmitted between the signal transmitting unit 245 and the signal receiving unit 246, thereby enabling the position feedback module 24 to achieve different precision adjustments for the mirror and the bracket.
- the gear 247 may also be provided with a third gear section 2473, which is located on the side of the first gear section 2471 opposite to the second gear section 2472, so that the first gear section 2471 is located between the second gear section 2472 and the third gear section 2473.
- the first gear section 2471 may have a denser gear distribution than the other two sections, because when the rearview mirror 3 is gradually unfolded from the fully retracted position, within the entire travel range, the required precision for adjusting the brackets of the front and rear sections is relatively low, while the mirror adjustment of the middle section requires relatively high precision.
- the signal may be a laser signal. In other embodiments, the signal may be an infrared signal.
- this is merely illustrative, and other types of signals are also feasible, which can be adjusted according to specific usage environments and design requirements, and such embodiments also fall within the scope of the present disclosure.
- the position feedback module 24 may also include sensors disposed near the gear 247, which may sense signals reflecting the gear tooth size and/or tooth gap size of the first gear section 2471 and the second gear section 2472, and transmit the corresponding signals to the control module 23.
- sensors may be Hall sensors. Hall sensors are sensitive to magnetic fields and can therefore sense the positive and negative poles of the magnetic field. A positive and negative change in the magnetic field forms a pulse, and the number of pulses is used to calculate the stroke, so position feedback with different accuracies can be achieved through the gap density of different gears.
- the position feedback module 24 Some specific embodiments of the position feedback module 24 are described in detail above. It should be noted that, of course, the detailed schemes listed here are only exemplary and not restrictive. The specific schemes are not limited by the embodiments of the present disclosure. In other embodiments, the position feedback module 24 may also be other chips or circuits with feedback functions. Other forms of the position feedback module 24 not listed herein are contemplated, as long as they can achieve differentiated feedback of the position of the motor 22 to the control module 23 .

- the embodiment of the present disclosure sets a higher adjustment accuracy for the area relative to the mirror adjustment and sets a relatively lower adjustment accuracy for the area relative to the bracket adjustment, thereby achieving high-precision adjustment of the mirror surface of the rearview mirror 3 without changing the recognition accuracy of the controller.
- the cost of the rearview mirror module can be reduced, thereby reducing the cost of the vehicle.
