[0028] In order to describe the present utility model more clearly, the present utility model will be further described below with reference to the accompanying drawings.

[0029] In the following description, specific details of the examples are given to provide a deeper understanding of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.

[0030] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or their combinations.

[0031] In existing vehicle headlights, they generally include a lens body, a mounting bracket, and a heat dissipation part that are connected in sequence. Inside the mounting bracket, the required light is formed by the cooperation of an LED unit and a reflecting bowl structure. The light is emitted into the lens body, and the lens body makes the light emit in a preset light pattern based on the characteristics of the lens. In the above solution, the lens body is composed of two integrally formed lens parts. However, in actual production, it is found that there are errors in the forming process of the lens parts, and it is difficult to match the light pattern during the cooperation with the LED unit. A large amount of time is required to adjust and match to form a reasonable light path and then output the expected light pattern, resulting in a relatively low overall production efficiency. Therefore, there is an urgent need for a more reasonable direct-illumination vehicle headlight to solve the above-mentioned technical problems.

[0032] To solve the above-mentioned technical problems, the present application provides a direct-illumination vehicle headlight. Please refer to the attached Figure 1 to the attached Figure 6 , which includes a mounting frame 1 and a second light-emitting plate 44. Among them, one side of the mounting frame 12 is connected to the lens 11. A first light-emitting plate 3 and a reflecting bowl 2 are provided inside the mounting frame 1. An avoidance position is provided at the edge of the lens 11. One end of the mounting frame 1 away from the lens 11 is also connected with a mounting frame 12. The working light of the first light-emitting plate 3 is gathered and refracted by the reflecting bowl 2 and then emitted from the lens 11 to form a first direct light a. One end of the second light-emitting plate 44 is connected to the mounting frame 12, and the other end is directly connected to the direct-illumination lens 511. The direct-illumination lens 511 is exposed from the lens 11 through the avoidance position. The working light of the second light-emitting plate 44 is emitted through the direct-illumination lens 511 to form a second direct light b. The first direct light a and the second direct light b jointly form a preset light pattern.

[0033] In terms of the optical path adjustment during installation, the second light-emitting plate 44 and the first light-emitting plate 3 will not affect each other due to the covering characteristics of the reflecting bowl 2, and the operation of the first light-emitting plate 3 is more stable. The mounting frame 1 and the mounting frame 12 can ensure the rationality of the installation between each component of the first light-emitting plate 3, the second light-emitting plate 44, and the reflector. The present application abandons the corresponding integrated mechanism, and the second light-emitting plate 44 and the direct-illumination lens 511 are used to cooperate with the single lens 11 to jointly emit light to form a suitable light pattern. The split structure significantly reduces the processing difficulty, has more excellent light pattern consistency, and higher production efficiency.

[0034] In this embodiment, a direct-illumination reflecting cup 6 is further provided between the second light-emitting plate 44 and the direct-illumination lens 511. The direct-illumination reflecting cup is used to gather and transmit the working light of the second light-emitting plate 44 to the direct-illumination lens 511. Through the direct-illumination reflecting cup 6, the working light formed by the second light-emitting plate 44 can be sent to the direct-illumination lens 511 more concentratedly and efficiently, significantly increasing the utilization rate of the working light.

[0035] In this embodiment, a heat dissipation metal block 7 is provided between the mounting frame 12 and the second light-emitting plate 44, and a heat dissipation gap is reserved between the heat dissipation metal block 7 and the reflecting bowl 2; the heat dissipation metal block 7 is used to increase the heat dissipation effect on the second light-emitting plate 44, ensure that the second light-emitting plate 44 can work at an appropriate temperature, and effectively increase the overall service life of the vehicle lamp.

[0036] In a further solution, symmetrically arranged heat dissipation grooves 71 are provided on the opposite sides of the heat dissipation metal block 7 exposed to the mounting frame 1, and the heat dissipation grooves 71 extend to both ends of the heat dissipation metal block 7; it is not difficult to understand that multiple groups of heat dissipation grooves 71 are used to increase the area of the heat dissipation metal block 7 in contact with the air, and then dissipate heat to the air in the form of thermal radiation in sequence, realizing a more efficient heat dissipation and cooling effect.

[0037] In a further solution, the depth of the heat dissipation groove 71 decreases from the center of the heat dissipation metal block 7 towards the two side edges; it is not difficult to understand that the light-emitting units of the second light-emitting plate 44 are generally located at the center of its panel. Through the above settings, it is more in line with the arrangement of the light-emitting units of the second light-emitting plate 44; and since the depth of the heat dissipation groove 71 at the edge is relatively shallow, the overall strength of the heat dissipation metal block 7 can be ensured, and it can better serve as a connecting piece to support and fix the second light-emitting lamp board and the mounting frame 12.

[0038] In a further solution, multiple groups of heat dissipation fins 72 are provided on the surface of the heat dissipation metal block 7 close to the mounting frame 1; the multiple groups of heat dissipation fins 72 can further increase the heat dissipation area to achieve a better heat dissipation effect; in a better solution, a heat dissipation channel is formed between the heat dissipation fins 72 and the second light-emitting lamp board, which can increase the contact area with the air, and better dissipate heat from the second light-emitting lamp board by means of heat diffusion, increasing the service life.

[0039] In this embodiment, a radiator 8 is further included, and one end of the radiator 8 is connected to the end of the mounting frame 12 away from the lens 11; the radiator 8 can significantly dissipate heat from the first light-emitting plate 3. This part is prior art, so it will not be elaborated here.

[0040] In a better solution, a mounting platform for mounting the first light-emitting plate 3 is formed between the radiator 8 and the mounting frame 12. A part of the reflecting bowl 2 is mounted on the mounting platform to enclose the first light-emitting plate 3, and the other part extends into the mounting frame 1; through the mounting platform, the placement of the reflecting bowl 2 and the first light-emitting plate 3 can be realized, making the vehicle lamp more compact, and under this volume assembly, it is ensured that the optical paths formed by the first light-emitting plate 3 and the second light-emitting plate 44 will not interfere with each other, that is, it will not affect the light pattern.

[0041] In this embodiment, a movable baffle is further provided in the mounting bracket 1; when the movable baffle blocks the working light of the first light-emitting panel, the lighting state is switched to another mode; the movable baffle can block the flux of the first light-emitting panel, thereby reducing the light emission intensity, and thus realizing the switching between the high beam and the low beam. This part is prior art and will not be elaborated here.

[0042] In this embodiment, the light-emitting unit of the second light-emitting panel 44 has a plurality of them, and the number of direct light lenses 511 and the number of direct light reflectors are matched with the number of light-emitting units.

[0043] The advantages of the present utility model are as follows:

[0044] 1) In terms of the optical path adjustment during installation, the second light-emitting panel and the first light-emitting panel will not affect each other due to the covering characteristics of the reflecting bowl, and the operation of the first light-emitting panel is more stable. The mounting bracket and the mounting frame can ensure the reasonable installation of each component such as the first light-emitting panel, the second light-emitting panel, and the reflecting plate.

[0045] 2) This application abandons the corresponding integrated mechanism. The second light-emitting panel and the direct light lens are used to cooperate with the single lens to emit light together to form a suitable light pattern. The split structure significantly reduces the processing difficulty, has more excellent light pattern consistency, and higher production efficiency.

[0046] 3) The heat dissipation metal block is reasonably arranged and can balance the strength and heat dissipation performance.

[0047] The above discloses only several specific embodiments of the present utility model, but the present utility model is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
