Description

Technical Field

[0001] This utility model relates to the field of vehicle rearview mirror technology, and in particular to an EC anti-glare rearview mirror. Background Technology

[0002] With the continuous development of automotive electronics technology, electrochromic (EC) anti-glare rearview mirrors have become an important feature in modern vehicles because they can automatically adjust their reflectivity according to ambient light, effectively reducing the impact of strong glare from vehicles behind on the driver's vision at night. EC anti-glare rearview mirrors typically include an EC lens, a control circuit board (PCB), and a housing structure for mounting and encapsulating these components.

[0003] In existing technology, an EC anti-glare rearview mirror generally consists of a front cover, a rear cover, and a PCB board. The EC lens is usually fixed on the front cover, while the PCB board is located in the space enclosed by the front and rear covers. The PCB board is electrically connected to the EC lens via a data cable to control the photochromic properties of the EC lens.

[0004] In existing EC anti-glare rearview mirror technology, when the PCB board malfunctions or needs upgrading, the front cover must be removed from the rear cover assembly to access the internal PCB board for repair or replacement. However, since the front cover and EC lens are usually integrated or tightly fixed, the process of removing the front cover can easily cause physical damage to the EC lens, such as scratches, cracks, or detachment of the lens from the connecting circuitry.

[0013] Furthermore, the back cover assembly is provided with two fixing components, which are used to limit the connectors of the first data line and the second data line respectively.

[0014] Furthermore, the fixing component includes two limiting members, with an installation cavity formed between the two limiting members; a connecting groove is formed at the lower part of the limiting member, and a protrusion adapted to the connecting groove is formed on the side of the connector; the connector is inserted into the installation cavity, and the protrusion is inserted into the connecting groove, so that the fixing component limits the connector.

[0015] Furthermore, the limiting member and the connector are connected by a snap-fit ​​structure, which includes: a spring piece provided on the limiting member, a protrusion provided on the spring piece, and a groove opened on the side of the connector, wherein the protrusion and the groove cooperate with each other.

[0016] Furthermore, the PCB board is provided with a mounting base, and the PCB board is detachably connected to the connector via the mounting base.

[0017] Furthermore, the back cover assembly includes: a back cover, and a support fixedly connected to the outer wall of the back cover; the cable harness of the second data cable passes through the back cover and the support in sequence and is electrically connected to an external device.

[0018] Furthermore, the handle is provided on the side of the connecting seat away from the receiving cavity.

[0019] The beneficial effects of this utility model are as follows: by removing the connector from the perforation, the connector drives the mounting base and PCB board to be removed from the perforation.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1:

[0031] This embodiment provides an EC anti-glare rearview mirror, such as Figures 1-3 As shown, it includes: a rear cover assembly, a front cover 2, an EC mirror 3, a perforation 11, a connector 4, and a PCB board 5;

[0032] The rear cover assembly includes a rear cover 1 and a support base 12;

[0033] Specifically, the rear cover 1 has a support seat 12 fixedly connected to the middle of its rear side. The support seat 12 is used to fix the EC anti-glare rearview mirror inside the vehicle. The rear cover 1 includes a rear wall and a side wall, and the front side is open.

[0034] Front cover 2 is mounted on the rear cover assembly;

[0035] Specifically, the front cover 2 is connected to the front side of the rear cover 1 by a snap fastener, and the front cover 2 and the rear cover 1 form a receiving cavity; a through hole 21 is provided in the middle of the front cover 2, and the through hole 21 is used for the first data cable 9 to pass through and be electrically connected to the EC mirror 3.

[0036] EC mirror 3 is mounted on front cover 2;

[0037] Specifically, the EC mirror 3 is glued to the side of the front cover 2 away from the rear cover 1;

[0038] The rear cover 1 assembly has a through hole 11 that communicates with the receiving cavity;

[0039] Specifically, the lower part of the back cover 1 has a through hole 11 that communicates with the receiving cavity. The length and width of the through hole 11 are greater than or equal to the length and width of the PCB board 5, so that the PCB board 5 can be inserted into the receiving cavity through the through hole 11.

[0040] The connector 4 is detachably connected to the through hole 11;

[0041] Specifically, the connector 4 is fixedly connected to the back cover 1 by screws, and the connector 4 is embedded into the through hole 11; and a semi-circular handle 41 is fixedly connected to the side of the connector 4 away from the receiving cavity, which makes it easier for people to apply force to remove the connector 4 from the through hole 11.

[0042] PCB board 5 is mounted on connector 4 and located within the receiving cavity;

[0043] Specifically, a mounting base 6 is fixedly connected to the lower part of the PCB board 5, forming a T-shape with the mounting base 6. The mounting base 6 is fixedly connected to the connecting base 4 by screws, thereby firmly fixing the PCB board 5 to the connecting base 4. Output interfaces 7 and input interfaces 13 are formed on both sides of the upper part of the PCB board 5. The output interface 7 of the PCB board 5 is plugged into the connector 91 of the first data line 9, and the other end of the first data line 9 is electrically connected to the EC mirror 3. Thus, the PCB board 5 is electrically connected to the EC mirror 3 through the first data line 9. The first data line 9 is located inside the receiving cavity. The input interface 13 of the PCB board 5 is plugged into the connector 91 of the second data line 10, and the wire harness at the other end of the second data line 10 passes through the rear cover 1 and the support base 12 in sequence and is electrically connected to the external device. The external device is a photosensitive sensor and a power supply. The power supply is used to provide power to the PCB board 5 and the EC mirror 3. The photosensitive sensor is used to capture the external light source. By acquiring the external light source, it sends a command to the PCB board 5 so that the PCB board 5 controls the EC mirror 3 to change color.

[0044] When PCB board 5 needs to be replaced or repaired: the operator can unscrew the screws on connector 4, and then remove connector 4 from through hole 11 using handle 41. Connector 4 will cause mounting base 6 and PCB board 5 to be removed from through hole 11. In this embodiment, connectors 91 of the first data cable 9 and 91 of the second data cable 10 are not limited, but are directly stored in the receiving cavity. After PCB board 5 is removed, the operator can disconnect connectors 91 of the first data cable 9 and 91 of the second data cable 10 from output interface 7 and input interface 13 of PCB board 5 respectively, and then unscrew the screws on mounting base 6 to separate mounting base 6 from connector 4. The PCB board 5 is then removed for repair or replacement. After the PCB board 5 is repaired or replaced, the operator fixes the mounting base 6 and the connecting base 4 on the repaired or replaced PCB board 5 with screws. Then, the connector 91 of the first data cable 9 and the connector 91 of the second data cable 10 are inserted into the output interface 7 and the input interface 13 of the PCB board 5, respectively. Then, the PCB board 5 is inserted into the receiving cavity, and the connecting base 4 is fixed to the through hole 11 of the rear cover 1 with screws. This completes the repair and replacement of the PCB board 5. During the repair and replacement of the PCB board 5, it will not come into contact with the EC mirror 3, thereby avoiding damage to the EC mirror 3.

[0045] Example 2:

[0046] like Figures 4-6 As shown, this embodiment further includes, based on the first embodiment, two fixing components 8 are provided on the back cover 1 assembly, and the two fixing components 8 are respectively used to limit the connector 91 of the first data line 9 and the second data line 10.

[0047] The fixing component 8 includes two limiting members 81, and a mounting cavity 85 is formed between the two limiting members 81; a connecting groove 82 is formed at the lower part of the limiting member 81, and a protrusion 92 adapted to the connecting groove 82 is formed on the side of the connector 91; the connector 91 is inserted into the mounting cavity 85, and the protrusion 92 is inserted into the connecting groove 82, so that the fixing component 8 limits the connector 91.

[0048] Specifically, such as Figure 5 As shown, the mounting cavity 85 and the connecting groove 82 form a T-shaped mounting space. The upper part and the middle of the rear part of the mounting space are open to allow the data cable harness to pass through the mounting space. The upper part and the remaining part of the rear part of the mounting space are closed to prevent the connector 91 from moving upward and backward. The lower part of the mounting space is open to allow the lower side of the connector 91 to pass through and be plugged into the output interface 7 or input interface 13 of the PCB board 5. The front part of the mounting space is open to allow the structure to be inserted into the mounting space. The two sides of the connector 91 have protrusions 92 that are adapted to the connecting groove 82. The protrusions 92 are integrally formed with the outer shell of the connector 91. The protrusions 92 are inserted into the connecting groove 82 to prevent the connector 91 from moving downward. Thus, the above structure can limit the movement of the connector 91 in the upper, lower and rear directions. This allows the fixing component 8 to limit the connector 91.

[0049] Further explanation: The fixing component 8 and the through hole 11 are aligned, thereby aligning the connector 91 of the data cable with the through hole 11, and with the output interface 7 and input interface 13 on the PCB board 5. When the operator inserts the PCB board 5 into the receiving cavity, it can be pushed upwards directly, allowing the output interface 7 and input interface 13 of the PCB board 5 to directly connect with the corresponding connector 91. When the PCB board 5 is pulled downwards, the output interface 7 and input interface 13 of the PCB board 5 can also be directly separated from the corresponding connector 91, achieving the effect of convenient operation. Moreover, since the connector 91 is limited, the data cable harness will not be pulled during the pulling of the PCB board 5, thus preventing the data cable harness from becoming loose from the EC mirror 3 or from external devices.

[0050] Furthermore, the limiting member 81 and the connector 91 are connected by a snap-fit ​​structure, which prevents the connector 91 from moving out of the front of the installation space.

[0051] like Figure 6 As shown, the snap-fit ​​structure includes: a spring piece 84 provided on the limiting member 81, a protrusion 86 provided on the spring piece 84, and a groove 93 opened on the side of the connector 91, wherein the protrusion 86 and the groove 93 cooperate.

[0052] Specifically, the limiting member 81 has a receiving hole 83, which provides space for the deformation of the spring piece 84. One end of the spring piece 84 is fixedly connected to the rear side wall of the receiving hole 83, and the other end of the spring piece 84 has a protrusion 86. The protrusion 86 is semi-circular and integrally formed with the spring piece 84. The side of the connector 91 has a groove 93 that matches the protrusion 86. When the connector 91 is inserted into the installation space, the protrusion 86 will be engaged in the groove 93. The engagement of the protrusion 86 and the groove 93 can prevent the connector 91 from sliding out from the front of the installation space. When it is necessary to remove the connector 91 from the installation space, it is only necessary to apply a little force to push the connector 91 out from the front of the installation space.
