Description

Technical Field

[0001] This invention relates to the field of automotive turn signal technology, and in particular to an automotive turn signal, a rearview mirror assembly having the same, and an automotive vehicle. Background Technology

[0002] As cars are used more frequently and in more scenarios in our lives, safety is just as important as convenience. As an indirect field of vision device, the exterior rearview mirror is an important safety component in a car. It expands the driver's indirect field of vision. While maintaining a direct view of the road ahead, the driver can observe the indirect field of vision to the sides and rear by looking through the lenses of the left and right rearview mirrors, thus improving driving safety. When changing lanes, drivers usually first observe the surrounding road conditions in the lenses of the left and right exterior rearview mirrors, then activate the turn signal, and then proceed with the lane change maneuver.

[0003] Drivers use turn signals to communicate with pedestrians and other vehicles outside the vehicle. However, because the turn signals are located in a position that is not visible to the driver while driving (i.e., behind the rearview mirror), the driver cannot see the turn signals on the rearview mirror and must look down at the instrument panel to confirm whether the turn signals are on. This is inconvenient and poses a safety hazard. Furthermore, if the turn signals are damaged and cannot be turned on, the driver cannot check whether the turn signals are on from inside the vehicle. If the turn signals are not activated when the driver tries to turn them on, the driver may mistakenly believe that the turn signals are on, which can easily lead to traffic accidents over time. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a car turn signal and a rearview mirror assembly having the same, and a car, which enables the driver to determine whether the turn signal is on from inside the driver's cab, thus ensuring driving safety.

[0005] This invention provides an automotive turn signal, comprising a base, a turn signal cover, and a lamp; the base and the turn signal cover are connected and enclose a receiving space between them, the lamp is installed in the receiving space, the turn signal cover has a light-transmitting area for transmitting light from the lamp, the base includes a base body and a light-transmitting part, the base body has an installation opening communicating with the receiving space, the light-transmitting part is installed on the installation opening of the base body, and the light-transmitting part is made of a light-transmitting material for transmitting light from the lamp.

[0034] like Figure 1 and Figure 2As shown, this embodiment provides a car turn signal, including a base 10, a turn signal cover 20, and a lamp 30. The base 10 and the turn signal cover 20 are connected, and the base 10 and the turn signal cover 20 enclose a receiving space. The lamp 30 is installed in the receiving space. The turn signal cover 20 has a light-transmitting area for transmitting the light from the lamp 30. In this embodiment, the turn signal cover 20 is made of PMMA (polymethyl methacrylate) material. PMMA material has good light transmittance. That is, in this embodiment, the entire turn signal cover 20 is a light-transmitting area, and all parts of the turn signal cover 20 can transmit light so that when the lamp 30 is turned on, the light emitted by the lamp 30 is projected out by the turn signal cover 20 to alert pedestrians or vehicles outside. The base 10 includes a base body 11 and a light-transmitting part 12. The base body 11 has an installation opening 111 that communicates with the receiving space. The light-transmitting part 12 is installed on the installation opening 111 of the base body 11, and the shape of the light-transmitting part 12 matches the installation opening 111. This allows the light emitted by the lamp 30 located in the receiving space to simultaneously illuminate the turn signal cover 20 and the light-transmitting part 12 on the base body 11. The light-transmitting part 12 is made of a light-transmitting material and is used to transmit the light from the lamp 30. When the lamp 30 is illuminated, the light emitted by the lamp 30 can simultaneously illuminate the turn signal cover 20 and the light-transmitting part 12. The turn signal cover 20 is used as a traditional turn signal, and the light-transmitting part 12 can be positioned on the rearview mirror in a position visible to the driver. In this embodiment, the light-transmitting part 12 is made of PC (polycarbonate), and the base body 11 is made of an opaque material, such as ABS (a terpolymer of acrylonitrile, butadiene, and styrene). The use of an opaque material for the base body 11 reduces light loss from the light emitted by the lamp 30. The base body 11 and the light-transmitting part 12 are manufactured using a two-color injection molding process, which ensures the airtightness of the base 10.

[0035] In the automotive turn signal provided in this embodiment, when the lamp 30 is illuminated, the light emitted by the lamp 30 can simultaneously illuminate the turn signal cover 20 and the light-transmitting part 12 on the base body 11. This allows the light emitted by one lamp 30 to illuminate two locations: the turn signal cover 20 and the light-transmitting part 12 on the base body 11. The light transmitted outward from the turn signal cover 20 serves to alert pedestrians or other vehicles outside the vehicle to the driver's upcoming turn operation. The light transmitted outward from the light-transmitting part 12 serves to alert the driver. Since the light transmitted by the turn signal cover 20 and the light-transmitting part 12 both originate from the same lamp 30, the driver can know that the turn signal cover 20 is also transmitting light when the light-transmitting part 12 transmits light. Before turning on the turn signal to change lanes, the driver can observe whether the light-transmitting part 12 is illuminated when checking the rearview mirror, thus knowing whether the turn signal is illuminated. There is no need to look down at the instrument panel to confirm whether the turn signal is on, improving driving safety. Furthermore, when the lamp 30 is damaged and cannot be lit, it can be determined by observing the light-transmitting part 12 that the lamp 30 is not lit, and thus the turn signal is not illuminated, allowing for timely maintenance of the lamp 30 and improving driving safety.

[0036] Turn signals are positioned on the rearview mirror where the driver cannot directly see them. This is because turn signals need to be designed to have sufficient brightness and a sufficiently conspicuous color to warn pedestrians and vehicles outside the vehicle. Therefore, the light from turn signals is relatively dazzling. To avoid visual interference from this glare, the turn signals are positioned in a location inaccessible to occupants (i.e., behind the rearview mirror), ensuring the driver cannot see the turn signal on the rearview mirror when it is activated. This prevents the driver from being blinded by the turn signal while checking the rearview mirror during lane changes, thus avoiding traffic accidents.

[0037] In this embodiment, the light transmitted by the turn signal cover 20 and the light-transmitting part 12 is provided by the same lamp 30. To prevent the light transmitted by the light-transmitting part 12 from dazzling the driver's eyes, the material of the light-transmitting part 12 in this embodiment is PC, and the light transmittance is 40%-70%. By adding pigments or additives to the PC material to reduce the light transmittance, when the lamp 30 emits high brightness and bright colors, the brightness of the light transmitted by the light-transmitting part 12 can be reduced. When the driver changes lanes and looks in the rearview mirror, the light transmitted through the light-transmitting part 12 will not dazzle their eyes, thus ensuring driving safety.

[0038] Furthermore, such as Figure 2As shown, the base body 11 includes a base plate, on which a first flange 113 extends around its periphery in a direction away from the base plate, and a mounting opening 111 is formed on the base plate. A second flange 22 extends from the turn signal cover 20, and the second flange 22 of the turn signal cover 20 is connected to the first flange 113 of the base body 11 by vibration friction welding. This allows the turn signal cover 20 and the base body 11 to form an accommodating space inside them after being enclosed, providing installation space for the lamp 30. This also allows the turn signal cover 20 and the base plate of the base body 11 to be separated by a certain distance, which is convenient for the turn signal cover 20 and the light-transmitting part 12 to be positioned at different positions on the rearview mirror when the turn signal is installed on the rearview mirror, so that the driver can see the light-transmitting part 12 but cannot see the turn signal cover 20. A PCB board 40 is housed within the base 10. The lamp 30 is mounted on the PCB board 40. The PCB board 40 is electrically connected to the vehicle's infotainment system via wires 50 passing through a wire 50 port 112 on the base body 11, supplying power to the lamp 30 on the PCB board 40. The base body 11 has a first end 13 and a second end 14. The PCB board 40 is located within the accommodating space and close to the first end 13 of the base body 11. The illumination direction of the lamp 30 is from the first end 13 of the base body 11 towards the second end 14. The light-transmitting portion 12 is elongated, and its length extends from the first end 13 to the second end 14 of the base body 11. A first extension 121 extends from the second end 14 of the light-transmitting portion 12 away from the turn signal cover 20. The turn signal cover 20 has a second extension 21 extending away from the base 10. When the base 10 is installed inside the rearview mirror, the first extension 121 and the second extension 21 can extend out of the rearview mirror housing to provide a warning effect to the outside of the vehicle. The first extension 121 provides the driver with reference information to know whether the turn signal cover 20 is illuminated, and the second extension 21 provides warning information to pedestrians or vehicles outside the vehicle to avoid collisions.

[0039] In summary, the automotive turn signal provided in this embodiment can simultaneously signal lane changes to pedestrians or other vehicles outside the vehicle and signal to the driver inside the vehicle that the turn signal is working properly. When changing lanes, the driver does not need to look down at the dashboard to confirm whether the turn signal is on, improving driving safety. Furthermore, if the turn signal is damaged and cannot illuminate, the light-transmitting part 12 allows for timely detection of the malfunction, enabling maintenance and preventing accidents caused by the driver being unaware of a lane change and the vehicle's inability to communicate lane change information for an extended period.

[0040] like Figure 3 and Figure 4As shown, this embodiment also provides a rearview mirror assembly 60, including a rearview mirror housing and a vehicle turn signal as described above. The rearview mirror housing includes a mirror housing 62 and a mirror ring 61, which together form the rearview mirror housing. The mirror housing 62 and mirror ring 61 form an internal space, within which the various components of the rearview mirror are installed. The mirror housing 62 is connected to the vehicle body, and the mirror ring 61 is used to mount the mirror lens 63. This rearview mirror structure is a conventional structure. The mirror ring 61 is closer to the driver's cab, allowing the driver to directly observe it from inside the cab. The mirror housing 62, located "behind" the mirror ring 61, is further away from the driver's cab, preventing the driver from directly observing all the information from inside the cab. The mirror ring 61 and the mirror housing 62 are respectively provided with a first light-transmitting opening and a second light-transmitting opening. The first light-transmitting opening is provided on the mirror ring 61 and the second light-transmitting opening is provided on the mirror housing 62. The turn signal cover 20 and the base 10 are installed inside the rearview mirror housing. The light-transmitting part 12 transmits light to the outside of the mirror ring 61 through the first light-transmitting opening, and the turn signal cover 20 transmits light to the outside of the mirror housing 62 through the second light-transmitting opening.

[0041] By placing the light-transmitting part 12 at the first light-transmitting opening on the mirror ring 61, the driver can determine whether the turn signal is on by observing whether the light-transmitting part 12 at the first light-transmitting opening is illuminated from inside the driver's cab. This allows for convenient observation of the light-transmitting part 12 at the first light-transmitting opening on the mirror ring 61 while performing lane-changing maneuvers. The turn signal cover 20 is positioned at the second light-transmitting opening on the mirror housing 62. The driver cannot observe the turn signal cover 20 at the second light-transmitting opening on the mirror housing 62 from inside the driver's cab. When the light fixture 30 is on, the light transmitted from the turn signal cover 20 will not dazzle the driver's eyes, improving driving safety.

[0042] Furthermore, the mirror ring 61 has a lens mounting position, where the lens 63 of the rearview mirror is mounted. A third extension 611 extends along the periphery of the lens mounting position away from the mirror housing 62 on the mirror ring 61, and a first light-transmitting opening is located on the third extension 611. The first light-transmitting opening on the third extension 611 facilitates the driver's observation of the light-transmitting portion 12 at the first light-transmitting opening. When the driver observes the lens 63 of the rearview mirror, they can use their peripheral vision to observe whether the light-transmitting portion 12 is illuminated. Furthermore, the first light-transmitting opening on the third extension 611 protects the light-transmitting portion 12 at the first light-transmitting opening. Collisions or friction between the rearview mirror housing and external objects typically occur on the outer side of the mirror housing 62, while the third extension 611 is located on the inner side of the mirror housing 62. When the rearview mirror housing collides with a pedestrian or vehicle, the collision is unlikely to occur at the first light-transmitting opening, thus preventing damage or dislodging of the light-transmitting portion 12 during collisions. It should be understood that the first light-transmitting opening should be located on the third extension 611 in a position that the driver can observe, so that when the driver is performing a lane change operation and observing the lens 63 of the rearview mirror, he can also observe the light-transmitting part 12 at the first light-transmitting opening.

[0043] In summary, the rearview mirror assembly 60 provided in this embodiment can prevent the turn signal from flashing into the driver's eyes when the driver turns on the turn signal, and can also indicate to the driver that the turn signal is on through the light-transmitting part 12 at the first light-transmitting opening on the mirror housing 62. The driver can know this during the lane change operation without having to spend time checking whether the turn signal is on.

[0044] This embodiment also provides a vehicle including the rearview mirror assembly 60 as described above.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
