[0036] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] Embodiment 1

[0038] This embodiment relates to a rearview mirror assembly, which has a simple structure, is convenient to be arranged on a vehicle, and is beneficial to reducing the production cost of the vehicle when applied to the vehicle.

[0039] To better understand the rearview mirror assembly of this embodiment, it should be noted first that the rearview mirror assembly mentioned in this embodiment particularly relates to a frameless rearview mirror assembly, especially applicable to the exterior rearview mirror of a vehicle, which can be either the left rearview mirror or the right rearview mirror of the vehicle. For the convenience of description, it is collectively referred to as the rearview mirror in this embodiment.

[0040] Based on the above design concept, an exemplary structure of the rearview mirror assembly of this embodiment is as Figure 1 and Figure 4 shown. In terms of the overall structure, the rearview mirror assembly of this embodiment can refer to the structure of the existing frameless exterior rearview mirror assembly. It mainly includes a mirror base 1, a mirror housing 2 rotatably mounted on the mirror base 1, and a mirror body 3 fixedly arranged on the mirror housing 2. Among them, the structures, connection relationships of the mirror base 1, the mirror housing 2 and the mirror body 3, as well as the installation method of the rearview mirror assembly can all refer to the prior art.

[0041] To better understand the rearview mirror assembly of this embodiment, a brief description of the structure of the rearview mirror assembly will be given here. Still as Figure 1 shown, the mirror base 1 is generally fixedly installed on the vehicle door, the mirror housing 2 is rotatably installed on the mirror base 1, and the mirror body 3 is installed on the mirror housing 2. The mirror surface 301 of the mirror body 3 is Figure 1 the side of the mirror body 3 that can be seen in the figure. The mirror housing 2 and the mirror body 3 are assembled and connected as a whole and rotate relative to the mirror base 1 together.

[0042] Generally, a driving component is connected between the mirror base 1 and the mirror housing 2. The driving component is used to drive the mirror housing 2 to rotate relative to the mirror base 1 to achieve functions such as horizontal adjustment, vertical adjustment, and horizontal folding. For example, in a rearview mirror assembly structure, a driving component is installed on the mirror housing 2, and the power output end of the driving component is connected to the mirror base 1. The power output end of the driving component outputs power, which can drive the mirror housing 2 to achieve functions such as horizontal adjustment, vertical adjustment, and horizontal folding relative to the mirror base 1.

[0043] In this embodiment, a CAN controller 4 is provided on the mirror base 1 or the mirror housing 2. The aforementioned driving component is electrically connected to the CAN controller 4, and at the same time, the CAN controller 4 is used to be electrically connected to the vehicle host computer 15. With such a setting, control information can be sent from the vehicle host computer 15 to the CAN controller 4, and the CAN controller 4 controls the driving component to act.

[0044] The rearview mirror assembly of this embodiment can solve the control conflict problem of the frameless rearview mirror based on the developed electrical architecture platform, avoid the non-commonality and design change cycle cost investment caused by the design change of the host computer 15, and the rearview mirror assembly can be better transplanted to various different architecture platforms. At the same time, it can also solve the problems of long signal transmission delay and poor network topology compatibility of the LIN controller.

[0045] In order to facilitate the installation of the rearview mirror assembly, as a preferred embodiment, a receiving cavity is formed between the mirror housing 2 and the mirror body 3, the driving component and the CAN controller 4 are both installed in the receiving cavity, and the power output end of the driving component extends out of the receiving cavity and is transmission-connected to the mirror base 1. In this structure, the driving component and the CAN controller 4 are both installed in the receiving cavity, so that the rearview mirror assembly has a simple appearance, is convenient for arrangement on the vehicle, and is convenient for hiding the wiring harness.

[0046] As a preferred embodiment, the aforementioned driving component includes a motor assembly 5, in which a horizontal adjustment motor 501 and a vertical adjustment motor 502 are integrated, and the power output ends of the horizontal adjustment motor 501 and the vertical adjustment motor 502 are respectively connected to the mirror base 1 in a transmission manner. In this way, the left-right adjustment function of the mirror base 1 can be realized by the horizontal adjustment motor 501, and the up-and-down adjustment function of the mirror base 1 can be realized by the vertical adjustment motor 502. The CAN controller 4 is electrically connected to the horizontal adjustment motor 501 and the vertical adjustment motor 502 respectively through a wiring harness, and the connection cost is low. The CAN controller 4 and the motor assembly 5 are both located in the accommodating cavity, and the wiring harness is also convenient to arrange.

[0047] It should be noted that if Figure 2 and Figure 3 As shown, 8 terminals need to be integrated on the CAN controller 4 in this embodiment. For the convenience of description, the 8 terminals of the CAN controller 4 are referred to as the first terminal 401, the second terminal 402, the third terminal 403, the fourth terminal 404, the fifth terminal, the sixth terminal 406, the seventh terminal 407 and the eighth terminal respectively.

[0048] like Figure 2 As shown, as a preferred embodiment, the CAN controller 4 is electrically connected to the horizontal adjustment motor 501 through the first wiring harness 8 and the second wiring harness 9 , and the CAN controller 4 is electrically connected to the vertical adjustment motor 502 through the third wiring harness 10 and the fourth wiring harness 11 .

[0049] Specifically, the first terminal 401 of the CAN controller 4 is electrically connected to one terminal of the horizontal adjustment motor 501 through the first wire harness 8, and the second terminal 402 of the CAN controller 4 is electrically connected to the other terminal of the horizontal adjustment motor 501 through the second wire harness 9. The third terminal 403 of the CAN controller 4 is electrically connected to one terminal of the vertical adjustment motor 502 through the third wire harness 10, and the fourth terminal 404 of the CAN controller 4 is electrically connected to the other terminal of the vertical adjustment motor 502 through the fourth wire harness 11.

[0050] In order to facilitate monitoring the position of the mirror base 1 after the horizontal adjustment motor 501 and the vertical adjustment motor 502 drive the rearview mirror assembly to rotate, as a preferred embodiment, a first potentiometer 12 and a second potentiometer 13 are integrated in the motor assembly 5. The resistance parts of the first potentiometer 12 and the second potentiometer 13 are respectively connected to the power supply terminal 405 and the ground terminal 408 of the CAN controller 4. The slider of the first potentiometer 12 is electrically connected to the sixth terminal 406 of the CAN controller 4, and the slider of the second potentiometer 13 is electrically connected to the seventh terminal 407 of the CAN controller 4. Among them, the power supply terminal 405 is the fifth terminal of the CAN controller 4, and the ground terminal 408 is the eighth terminal of the CAN controller 4.

[0051] In this embodiment, the first potentiometer 12 and the second potentiometer 13 are integrated in the motor assembly 5, and the resistance parts of the first potentiometer 12 and the second potentiometer 13 are respectively connected to the power supply terminal 405 and the ground terminal 408 of the CAN controller 4. The sliders of the first potentiometer 12 and the second potentiometer 13 are respectively electrically connected to the CAN controller 4, which is convenient for judging the up, down, left and right positions of the rearview mirror according to the voltages of the first potentiometer 12 and the second potentiometer 13. These information can be transmitted to the host computer 15 for memory, which is convenient for realizing functions such as horizontal adjustment, vertical adjustment, horizontal folding and linkage memory.

[0052] Specifically, the position of the mirror base 1 after horizontal rotation can be judged by monitoring the voltages of the sixth terminal 406 and the eighth terminal, and the position of the mirror base 1 after vertical rotation can be judged by detecting the voltages of the seventh terminal 407 and the eighth terminal.

[0053] It should be noted that, as a preferred embodiment, the rearview mirror assembly of this embodiment is a frameless exterior rearview mirror assembly. In this way, the modification to the existing frameless exterior rearview mirror structure is relatively small, and when this frameless exterior rearview mirror is applied to a vehicle, when arranging on the vehicle, only the layout of the main wire harness 7 between the CAN controller 4 and the host computer 15 needs to be considered. The main wire harness 7 is arranged through the mirror base 1 to facilitate connection with the host computer 14, and the modification to the existing vehicle parts is also relatively small, which is beneficial to reducing the vehicle cost. The rearview mirror is a frameless exterior rearview mirror, with a simple appearance and a wider field of view.

[0054] In order to reduce the weight of the motor assembly 5, as a preferred embodiment, the horizontal adjustment motor 501 is a speed-adjustable motor, which can help to slowly realize the horizontal adjustment function of the rearview mirror and quickly realize the horizontal folding function of the rearview mirror, which is conducive to reducing the number of motors and reducing the production cost of the motor. It should be noted that the motor assembly 5 in this embodiment can be, for example, the existing motor assembly 5 of Ficosa Auto Parts Co., Ltd. or Magna Automotive Technology Co., Ltd.

[0055] The rearview mirror assembly in this embodiment can implement the overheat protection function of preventing the horizontal adjustment motor 501 and the vertical adjustment motor 502 by monitoring the driving current of the CAN controller 4 for the horizontal adjustment motor 501 and the vertical adjustment motor 502 respectively. Because the motor may overheat when the customer adjusts the rearview mirror assembly back and forth, monitoring the driving current of the horizontal adjustment motor 501 and the vertical adjustment motor 502 can realize the anti-playing function and the anti-jamming function.

[0056] The host computer 15 is preferably a vehicle control unit or an electronic control unit of a vehicle. Here, the host computer 15 uses a vehicle VCU (Vehicle Control Unit) or ECU (Electronic Control Unit) of the vehicle, and can use existing vehicle components to reduce the production cost of the vehicle.

[0057] As a preferred embodiment, the rearview mirror assembly of this embodiment further includes a rearview mirror switch 14, which is used to be installed on the interior of the vehicle, and the rearview mirror switch 14 is electrically connected to the host computer 15. Here, the rearview mirror switch 14 is provided to facilitate the up / down / left / right adjustment and horizontal folding functions of the rearview mirror, for example, a switch with up / down / left / right adjustment functions can be provided. It should be noted that the interior mentioned here can be, for example, the inner guard plate of the vehicle door, the armrest box or the center console.

[0058] Toggle the switch to the left for a short time, the mirror base 1 drives the mirror body 3 to rotate slowly to the left, and toggle the switch to the right for a short time, the mirror base 1 drives the mirror body 3 to rotate slowly to the right, to achieve the horizontal left and right adjustment function. Toggle the switch to the left for a long time, the mirror base 1 drives the mirror body 3 to rotate quickly to the left, and toggle the switch to the right for a long time, the mirror base 1 drives the mirror body 3 to rotate quickly to the right, to achieve the horizontal folding and opening function. Toggle the switch upward, the mirror base 1 drives the mirror body 3 to rotate upward, and toggle the switch downward, the mirror base 1 drives the mirror body 3 to rotate downward, to achieve the vertical up and down adjustment function.

[0059] For the convenience of overall layout, as a preferred embodiment, the rearview mirror switch 14 is integrated on the window glass switch of the vehicle. With this arrangement, the integration degree is high, it is convenient to be arranged on the vehicle, and the cost is relatively low. The LIN control line for the existing window glass lifting can also be used to realize functions such as horizontal adjustment, vertical adjustment and horizontal folding of the rearview mirror assembly.

[0060] As Figure 4 shown, the eight arrows between the CAN controller 4 and the motor assembly 5 represent that eight wire harnesses need to be arranged. From top to bottom, the two uppermost ones represent the wire harnesses between the CAN controller 4 and the horizontal adjustment motor 501. The next two represent the wire harnesses between the CAN controller 4 and the vertical adjustment motor 502. The subsequent two represent the wire harnesses connecting the power supply terminal 405 and the ground terminal 408 of the CAN controller 4 to the potentiometer. The two lowermost ones respectively represent the wire harnesses of the sliders of the two potentiometers and the CAN controller 4. And two main wire harnesses 7 are directly arranged between the CAN controller 4 and the host computer 15 for information interaction between the CAN controller 4 and the host computer 15, and the existing LIN control wire harness for window glass lifting can be used between the rearview mirror switch 14 and the host computer 15.

[0061] In the solution of the rearview mirror assembly with the CAN controller 4 built in the frameless rearview mirror in this embodiment, it has the following advantages. The conflict with the existing host computer 15 can be minimized. The CAN controller 4 in the rearview mirror assembly is connected to the rearview mirror connector 6 through the main wire harness 7. The rearview mirror connector 6 can be, for example, an existing connector, which can be plugged into the mating connector on the upper computer, so that the rearview mirror assembly is connected to the existing CAN network segment, and only the corresponding interaction signals need to be added to the signal matrix.

[0062] In addition, since the various components on the motor assembly 5 are connected to the CAN controller 4 in the accommodation cavity, the connection length of the wire harness can be saved well. For the conventional domain control scheme for controlling two external rearview mirrors, 16 wire harness loop numbers are required, and the average length of a single wire exceeds 1.5 m. However, by adopting the technical scheme of the frameless rearview mirror with the CAN controller 4 built in, the CAN controller 4 and the motor assembly 5 are integrated in the accommodation cavity, and the loop number is reduced from the original 16 to 4, and both the cost and weight of the wire harness can be reduced.

[0063] In the rearview mirror assembly of this embodiment, the CAN controller 4 is installed on the mirror base 1 or the mirror housing 2 of the rearview mirror assembly, and the CAN controller 4 is electrically connected to the host computer 15 and the driving components of the rearview mirror assembly respectively, so that the integration degree of the rearview mirror assembly is high. When it is arranged on the vehicle, it can be adapted to a variety of existing vehicle models, with less improvement to the vehicle components, and only two wire harnesses are used for each rearview mirror to be connected to the host computer 15. The wire harnesses are fewer, the cost is lower, and it is convenient to be arranged on the vehicle.
