Description

Technical Field

[0001] The utility model belongs to the technical field of automotive rearview mirrors, and particularly relates to a rearview mirror turn signal with segmented control. Background Technique

[0002] An automotive turn signal refers to, when a vehicle turns, by turning on the flashing indicator lights in the corresponding direction, to warn pedestrians or vehicles in front of or behind the vehicle and indicate the driving direction of the vehicle. Classified by position, automotive turn signals can be divided into front turn signals and side turn signals. The front turn signal is installed beside the automotive headlight and is used to warn the vehicle in front when turning; the rear turn signal is installed at the rear of the vehicle and is used to warn the vehicle behind when turning; the side turn signal is installed beside the door of the first driver's cab or on the rearview mirror and is used to warn the vehicle beside when turning.

[0003] The patent with the application number CN201922326973.5 discloses an external rearview mirror turn signal, which includes a lamp housing, a light source and a lamp cover. The lamp cover is connected to the lamp housing to jointly define a light guide cavity with the lamp housing. The light source is arranged in the lamp housing and located in the light guide cavity. In this light guide cavity, a light guide structure extending from near the light source towards away from the light source is arranged on the lamp housing or the lamp cover. This light guide structure is used to guide the light emitted by the light source to propagate along the first direction. At least the part of the lamp cover corresponding to the light guide structure is light-transmitting. The light guide structure includes a plurality of light guide ribs extending transversely to the first direction. The plurality of light guide ribs are arranged at intervals along the first direction. The light guide structure has an adjacent near-light side and far-light side in the first direction. The distance between two adjacent light guide ribs gradually decreases from the near-light side to the far-light side direction. This external rearview mirror turn signal can make its own brightness uniform, but it is all on and all off as a whole. In order to enable vehicles or pedestrians to more intuitively and clearly judge the traveling direction of oncoming vehicles, the present application provides a rearview mirror turn signal with segmented control.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] Referring to the attached Figures 1-5 , a segmented-controlled rearview mirror turn signal, comprising:

[0030] A rearview mirror housing 1, with a receiving groove 2 opened at its front end; a circuit board 3 is provided inside the receiving groove 2, and multiple photosensitive sensors 4 are arranged on the circuit board 3; a first limiting block 5 and a second limiting block 6 are also provided in the receiving groove 2, the first limiting block 5 is hollow inside and is provided with 1 trigger LED 7;

[0031] A turn signal assembly, located in the receiving groove 2, with a transparent windshield at its front end; the turn signal assembly includes multiple groups of light-emitting lamp groups 8; the light-emitting lamp groups 8 are arrow-shaped, and their tips are arranged facing away from the car door; the first limiting block 5 and the second limiting block 6 are respectively located on both sides of the multiple groups of light-emitting lamp groups 8;

[0032] A partition 9, located between two adjacent light-emitting lamp groups 8; a first light guide groove 10 for placing the photosensitive sensor 4 is opened at the rear end of the partition 9, and a second light guide groove 11 communicating with the first light guide groove 10 is opened on its side wall; the second light guide groove 11 faces the direction of the car door.

[0033] In this embodiment, the photosensitive sensor 4 is a photosensitive diode connected to the circuit, and the photosensitive circuit is a relatively mature existing technology and will not be elaborated here. Multiple protrusions for cooperating with the light-emitting lamp groups 8 are provided on the side of the first limiting block 5 away from the car door; multiple grooves for cooperating with the light-emitting lamp groups 8 are opened on the side of the second limiting block 6 facing the car door, so that the multiple light-emitting lamp groups 8 as a whole present a strip-shaped light belt with the tip facing outwards. The first light guide groove 10 and the second light guide groove 11 are located in the rear half of the partition 9, and the front half of the partition 9 is a transparent cavity. Similarly, both the first limiting block 5 and the second limiting block 6 are made of a hollow transparent material structure, which can expand the illumination range when the light-emitting lamp groups 8 are lit, making the illuminated area of the rearview mirror appear larger.

[0034] It should be noted that the light-emitting lamp groups 8 are divided into four layers, and 1 light-emitting LED 12 is provided in each layer. The upper three light-emitting LEDs 12 are not on the same vertical plane, and the light-emitting LED 12 of the lowermost layer is on the same vertical plane as the light-emitting LED 12 of the second layer. Such an arrangement can make the light-emitting lamp groups 8 present an arrow shape when lit, and can more intuitively and clearly indicate the driving direction of the vehicle.

[0035] In addition, multiple light-blocking horizontal plates 13 are provided in the receiving groove 2, and both ends of the light-blocking horizontal plates 13 are fixed to the first limiting block 5 and the second limiting block 6 respectively. The light-blocking horizontal plates 13 can separate different layers of the light-emitting lamp groups 8 to prevent mutual triggering when the light-emitting LEDs 12 of different layers are lit.

[0036] During actual use, the driver toggles the turn signal lever in the cab, and the control circuit starts to work, causing the corresponding trigger LED7 to light up and flash, serving as the most basic turn indication. When the trigger LED7 flashes once, the photosensitive sensor 4 in the light guide groove 10 of the partition 9 on one side of it converts the optical signal into an electrical signal, enabling the circuit of the rear light-emitting lamp group 8 to conduct, and lighting up the light-emitting LEDs 12 on each layer of the light-emitting lamp group 8. The lit light-emitting LEDs 12 will trigger the photosensitive sensor 4 inside the partition 9 on the other side of them, causing the rear light-emitting lamp group 8 to be lit.

[0037] Since there is a certain interval between the flashes of the trigger LED7, the light-emitting LEDs 12 of the subsequent lit light-emitting lamp group 8 flash alternately, presenting a phenomenon that the arrow-shaped light spot moves outwards, which is conducive to clearly and intuitively indicating the situation of the vehicle about to turn.

[0038] The segmented-controlled rearview mirror turn signal of the present utility model uses the trigger LED7 that lights up or goes out as a whole. While retaining the existing reminder method of the rearview mirror turn signal, it cooperates with the photosensitive sensor 4 to light up the rear light-emitting lamp group 8, and the display pattern of the arrow-shaped light spot moving outwards more clearly and intuitively shows the traveling direction of the vehicle, which is more conducive to oncoming vehicles and pedestrians to make judgments. It is very practical and has a good market application prospect.

[0039] The foregoing description of the specific exemplary embodiments of the present utility model is for the purposes of illustration and exemplification. These descriptions are not intended to limit the present utility model to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present utility model and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present utility model, as well as various different selections and changes. The scope of the present utility model is intended to be defined by the claims and their equivalents.
