Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0022] A rearview mirror assembly 1 for a vehicle according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0023] According to the present application, the rearview mirror assembly 1 for a vehicle includes a mirror support plate 11, a lens 12, a light guide 13 and a light-emitting unit. The mirror support plate 11 is provided with a mounting surface 112, and a receiving groove 111 is formed on the mirror support plate 11, and the open mouth of the receiving groove 111 faces the mounting surface 112; the lens 12 is arranged on the mirror support plate 11 and covers the mounting surface 112 and the open mouth of the receiving groove 111; the light guide 13 is accommodated in the receiving groove 111, and the light guide 13 is formed with a light input surface 131 and a light output surface 132 facing the lens 12, and the light guide 13 is suitable for guiding the light entering from the light input surface 131 to the light output surface 132; the light-emitting unit is accommodated in the receiving groove 111 and the light-emitting unit is formed with a light-emitting portion, which is opposite to the light input surface 131, and the light-emitting portion projects light to the lens 12 through the light guide 13.

[0024] In some embodiments, a mounting surface 112 is formed on the mirror support plate 11, and the lens 12 can cover the entire mounting surface 112 and be mounted on the mirror support plate 11. A receiving groove 111 is also formed on the mirror support plate 11, and the opening of the receiving groove 111 faces the mounting surface 112. The light guide 13 and the light emitting unit are both arranged in the receiving groove 111. After the lens 12 is mounted on the mirror support plate 11, the lens 12 can cover the entire mounting surface 112 and the opening of the receiving groove 111, ensuring that the light guide 13 and the light emitting unit are sealed between the mirror support plate 11 and the lens 12, avoiding the light guide 13 and the light emitting unit from being damaged by water, and the mirror support plate 11 is integrated with the lens 12. The lens 12, the light guide 13 and the light-emitting unit are integrated, which greatly reduces the weight of the vehicle rearview mirror; the light guide 13 is formed with a light inlet surface 131 and a light outlet surface 132 facing the lens 12, and the light guide 13 can reflect the light entering the light inlet surface 131 into the lens 12 through the light outlet surface 132, so that the light emitted by the light guide 13 is more concentrated, the luminous intensity of the light guide 13 is improved, and the divergence of the light is reduced; a light-emitting part is formed on the light-emitting unit, and the light-emitting part is opposite to the light inlet surface 131. The light-emitting part emits light to the light inlet surface 131 and projects the light to the lens 12 through the light guide 13, thereby reminding the driver of the blind spot of the vehicle.

[0025] The rearview mirror assembly 1 for a vehicle according to the present application is provided with a mounting surface 112 and a receiving groove 111 on the mirror support plate 11, thereby integrating the light guide 13, the light emitting unit and the lens 12 on the mirror support plate 11, reducing the connecting parts and connecting lines, and greatly reducing the weight of the vehicle rearview mirror. After the lens 12 is installed on the mirror support plate 11, the lens 12 covers the entire mounting surface 112 and closes the open mouth of the receiving groove 111, thereby preventing the light guide 13 and the light emitting unit from failing due to water ingress, thereby improving safety. A light inlet surface 131 and a light outlet surface 132 are formed on the light guide 13, and the light emitting unit projects light onto the light inlet surface 131 through a light emitting part. The light emitting part can be constructed in multiple ways, and the light outlet surface 132 of the light guide 13 concentrates the light emitted by the light emitting part onto the lens 12. The light guide 13 and the light emitting unit cooperate to make the light projected by the lens 12 more uniform and the light intensity higher, thereby ensuring aesthetics, making the warning effect on the driver more obvious, and ensuring the safety of the passengers in the vehicle.

[0026] According to some embodiments of the present application, the light-incoming surface 131 and the light-emitting surface 132 of the light guide 13 are orthogonal.

[0027] In some embodiments, since the light-emitting surface 132 is arranged toward the lens 12 and projects the light projected into the light-incoming surface 131 onto the lens 12, and the light-incoming surface 131 is directly opposite to the light-emitting portion of the light-emitting unit, the light-incoming surface 131 and the light-emitting surface 132 of the light guide 13 are arranged orthogonally, which can ensure that the depth of the receiving groove 111 for accommodating the light guide 13 will not be too deep, the arrangement of the light guide 13 and the light-emitting unit is also more convenient, and the processing technology of the receiving groove 111 in the mirror support plate 11 is also simpler.

[0028] According to some embodiments of the present application, the light guide 13 is formed with a reflective surface 133, which is inclined relative to the light input surface 131 and the light output surface 132, respectively. The angle between the reflective surface 133 and the light input surface 131 and the angle between the reflective surface 133 and the light output surface 132 are complementary angles.

[0029] In some embodiments, a reflective surface 133 is formed on the light guide 13, and the light projected by the light-emitting portion into the light-input surface 131 is reflected by the reflective surface 133 and thus projected onto the light-output surface 132, and finally the light is projected onto the lens 12. In some embodiments, the reflective surface 133 is tilted relative to the light-input surface 131 and the light-output surface 132, respectively, which can more effectively change the reflection path of the light and ensure that the light can be projected onto the light-output surface 132. The angle between the reflective surface 133 and Jin Guangjian and the angle between the reflective surface 133 and the light-output surface 132 are complementary angles to each other, which can ensure that the light reflected by the reflective surface 133 can be concentrated on the light-output surface 132 and projected onto the lens 12, so that the light projected by the light guide 13 is more concentrated and uniform, and the light intensity is higher, thereby improving the reminder effect of the rearview mirror assembly 1 on the driver.

[0030] According to some embodiments of the present application, the light guide 13 is constructed in an arc shape, the inner peripheral surface of the light guide 13 is constructed as a light input surface 131, a reflective surface 133 is formed on the outer peripheral surface of the light guide 13, and a light output surface 132 is formed on the end surface of the light guide 13 facing the lens 12.

[0031] In some embodiments, the light guide 13 is constructed in an arc shape, which increases the contact area between the light guide 13 and the light, and can improve the light gathering effect of the light guide 13. In some embodiments, the inner circumference of the light guide 13 is constructed as a light input surface 131, and the inner circumference is opposite to the light emitting part. The inner circumference is an arc-shaped surface, which can ensure that the light input surface 131 can collect all the light emitted by the light emitting part into the light guide 13 to prevent the light from dissipating. The outer circumference of the light guide 13 forms a reflecting surface 133 to prevent the light in the light guide 13 from diverging from the periphery of the light guide 13, and ensure that all the light in the light guide 13 is concentrated on the light output surface 132. The light output surface 132 is set toward the lens 12 to ensure that the light projected from the light guide 13 to the lens 12 is more concentrated and the light intensity is higher.

[0032] According to some embodiments of the present application, the light-emitting unit includes a circuit board 141 and a light-emitting component 142. The circuit board 141 is accommodated in the accommodating groove 111 and extends from one end of the light guide 13 to the other end of the light guide 13; the light-emitting component 142 is arranged on the side of the circuit board 141 facing the light guide 13 and is constructed as a light-emitting portion.

[0033] In some embodiments, the light-emitting unit and the light guide 13 are both arranged in the accommodating groove 111. The circuit board 141 can extend from one end of the light guide 13 to the other end of the light guide 13, so that the circuit board 141 is opposite to the light guide 13. The circuit board 141 is provided with a light-emitting component 142 on the side facing the light guide 13. Since the circuit board 141 is opposite to the light guide 13, the light emitted by the light-emitting component 142 can be more concentratedly projected onto the light guide 13 to avoid light dissipation, and the light projected from the light guide 13 to the lens 12 is more concentrated.

[0034] According to some embodiments of the present application, the light emitting elements 142 are configured in plurality and are arranged at intervals in the extension direction of the circuit board 141 .

[0035] In some embodiments, the light-emitting element 142 can be constructed as an LED (light-emitting diode), and the light-emitting element 142 can be constructed in multiple numbers, and the multiple light-emitting elements 142 are arranged at intervals in the extension direction of the circuit board 141. The multiple light-emitting elements 142 are all opposite to the light-incoming surface 131 of the light guide 13. The multiple light-emitting elements 142 project light onto the light-incoming surface 131, which can increase the intensity of light projected from the light guide 13 to the lens 12.

[0036] According to some embodiments of the present application, a connector 1411 is provided on the side of the circuit board 141 facing away from the light guide 13; the accommodating groove 111 includes a first groove body, a second groove body and a third groove body, the first groove body is constructed as an arc-shaped groove, and the first groove body is suitable for accommodating the light guide 13; the second groove body is suitable for accommodating the circuit board 141 and the light-emitting component 142 and is connected to the first groove body; the third groove body is connected to the second groove body and is suitable for accommodating the connector 1411.

[0037] In some embodiments, a connector 1411 is provided on the side of the circuit board 141 facing away from the light guide 13. The connector 1411 can be constructed as a plug-in circuit, which connects to a power source and energizes the light-emitting element 142. After being energized, the light-emitting element 142 emits light and projects it onto the light guide 13. The light-emitting component 142, the circuit board 141 and the light guide 13 are all accommodated in the accommodating groove 111. The accommodating groove 111 includes a first groove body, a second groove body and a third groove body. In some embodiments, the first groove body is constructed as an arc groove, the light guide 13 is arranged in the first groove body, the light-emitting component 142 and the circuit board 141 are accommodated in the second groove body, the second groove body is connected to the first groove body, the light emitted by the light-emitting component 142 can be directly projected into the light guide 13, the connector 1411 of the circuit board 141 is accommodated in the third groove body, the third groove body is connected to the second groove body, the circuit board 141 can be directly connected to the connector 1411 and energize the light-emitting component 142. The shape of the first groove body of the accommodating groove 111 matches the shape of the light guide 13, the shape of the second groove body matches the shape of the light-emitting component 142 and the circuit board 141, and the shape of the third groove body matches the shape of the connector 1411, which facilitates the assembly of the light guide 13, the light-emitting component 142, the circuit board 141 and the connector 1411.

[0038] According to some embodiments of the present application, a first limiting fitting portion is formed on the light guide 13, and a second limiting fitting portion is provided on the inner wall of the first groove body. One of the first limiting fitting portion and the second limiting fitting portion is constructed as a snap-fit ​​groove, and the other of the first limiting fitting portion and the second limiting fitting portion is constructed as a snap-fit ​​protrusion suitable for cooperating with the snap-fit ​​groove.

[0039] In some embodiments, a snap-in groove may be formed on the light guide 13, and the inner wall of the first groove body may be provided with a snap-in protrusion that cooperates with the snap-in groove. During the process of installing the light guide 13 into the first groove body, the snap-in protrusion in the first groove body cooperates with the snap-in groove on the light guide 13, so that the assembly of the light guide 13 and the first groove body is more stable, avoiding the shaking of the light guide 13, and the light projected onto the lens 12 by the light guide 13 is more stable, ensuring the warning effect of the rearview mirror assembly 1 for the driver. At the same time, the light guide 13 will not make noise due to shaking, thereby improving the riding comfort of the passengers.

[0040] According to some embodiments of the present application, a positioning hole 1412 penetrating in the thickness direction is formed on the circuit board 141 , and a positioning pin 1413 suitable for cooperating with the positioning hole 1412 is formed on the inner wall of the second slot.

[0041] In some embodiments, during the process of installing the circuit board 141 into the second slot body, the positioning pin 1413 on the inner wall of the second slot body cooperates with the positioning hole 1412 on the circuit board 141, and the circuit board 141 is stably accommodated in the second slot body, preventing the circuit board 141 from shaking, ensuring that the circuit board 141 will not be damaged due to shaking, and ensuring the safe use of the circuit board 141.

[0042] According to some embodiments of the present application, the rearview mirror assembly 1 further includes an adhesive layer 15 , which is disposed between the mounting surface 112 and the lens 12 . The adhesive layer 15 forms a relief opening 151 for avoiding the open opening.

[0043] In some embodiments, after the light guide 13 and the light emitting unit are fixedly received in the receiving groove 111, the lens 12 is mounted on the mirror support plate 11 and covers the mounting surface 112 and the receiving groove 111. In some embodiments, an adhesive layer 15 is provided between the lens 12 and the mounting surface 112 to ensure that the lens 12 is stably mounted on the mirror support plate 11.
