[0025] Please refer to Figure 1 As shown, the embodiment of the present application provides a headlight device, including: a ventilation component 10 and at least two optical modules. The ventilation component 10 has at least two ventilation channels 10a, and the ventilation directions of the at least two ventilation channels 10a have an included angle; each optical module includes an optical component 110 and a heat dissipation component 111. Each heat dissipation component 111 is provided with a heat dissipation channel formed by a heat dissipation structure. The ventilation channels 10a are respectively communicated with the heat dissipation channels. Among them, the heat dissipation structure of the heat dissipation component 111 of at least one optical module is a needle-shaped heat dissipation structure, and the needle-shaped heat dissipation structures are arranged in an array to form heat dissipation channels in multiple different directions.
[0026] The optical module is used to provide vehicle lighting. Generally, the optical module includes any one or more of a low-beam optical module, a high-beam optical module, an auxiliary low-beam optical module, and an auxiliary high-beam optical module; the ventilation component 10 cooperates with the heat dissipation component 111 of the optical module to dissipate heat from the optical component 110. The heat generated when the optical component 110 works is taken away through the heat dissipation component 111 and the ventilation component 10 to ensure the normal working performance of the optical component 110.
[0027] In this application, there are at least two optical modules. Each optical module may include an optical component 110 and a heat dissipation component 111. The heat dissipation structure of the heat dissipation component 111 forms a heat dissipation channel. The heat dissipation channels of at least two optical modules are connected to the same ventilation component 10 for heat dissipation. The ventilation component 10 may have ventilation channels 10a corresponding to the number of optical modules. The heat dissipation component 111 of each optical module may be located on one side of the corresponding ventilation channel 10a; the ventilation directions of at least two ventilation channels 10a have an included angle to facilitate the arrangement of the corresponding at least two optical modules.
[0028] In this application, the heat dissipation channel of the heat dissipation component 111 can be formed by a heat dissipation structure, such as Figure 1 As shown, the heat dissipation structure of the heat dissipation component 111 of at least one optical module in this application is a needle-shaped heat dissipation structure. For example, the heat dissipation component 111 of one optical module is a needle-shaped heat dissipation structure, and the heat dissipation component 111 of another optical module is a fin-type heat dissipation structure. The fin-type heat dissipation structure usually can only provide a heat dissipation channel in one direction, while the needle-shaped heat dissipation structure can provide heat dissipation channels in multiple directions. For the needle-shaped heat dissipation structure, on the one hand, it can better increase the heat dissipation area of the heat dissipation component 111 and improve the heat dissipation efficiency; on the other hand, the needle-shaped heat dissipation structure forms multiple heat dissipation channels in different directions through an array arrangement to adapt to the ventilation channels 10a in different directions. Thus, the heat dissipation area is large. The heat generated by the optical component 110 is transferred to the environment through the needle-shaped heat dissipation structure with a large surface area, and the heat is accelerated and dissipated by using the ventilation channel 10a. Through the cooperation of the ventilation channel 10a and the needle-shaped heat dissipation structure, the optical component 110 is efficiently cooled; at the same time, combined with the heat dissipation channels in different directions provided by the needle-shaped heat dissipation structure, it can cooperate with the ventilation channels 10a in different directions. Using one ventilation component 10 can correspond to the compact layout of at least two optical modules, and can also reduce the overall space occupation. In addition to meeting the heat dissipation requirements of multiple optical modules, it can also use the layout settings to reduce costs and improve the overall competitive advantage of the device.
[0029] Furthermore, the heat dissipation structures of the heat dissipation components 111 of each optical module in this application may all be needle-shaped heat dissipation structures; for example, as Figure 1As shown, the present application has two optical modules, namely the first optical module 11 and the second optical module 12. The heat dissipation structures of the heat dissipation components 111 of the two optical modules are both needle-shaped heat dissipation structures. Thus, while further improving the heat dissipation effect of the two optical modules, the flexible arrangement of the ventilation channels 10a can be achieved.
[0030] Correspondingly, the ventilation component 10 has two ventilation channels 10a. The two ventilation channels 10a respectively have a first ventilation direction F1 and a second ventilation direction F2, and an included angle is provided between the first ventilation direction F1 and the second ventilation direction F2.
[0031] As mentioned above, the needle-shaped heat dissipation structure forms a plurality of heat dissipation channels in different directions through an array arrangement. The array arrangement of the needle-shaped heat dissipation structure can at least form a first heat dissipation channel and a second heat dissipation channel, and the directions of the first heat dissipation channel and the second heat dissipation channel are different; among them, the extending direction of the first heat dissipation channel can be parallel to the first ventilation direction F1 to accelerate heat dissipation through the ventilation channel 10a in the first ventilation direction F1; the extending direction of the second heat dissipation channel can be parallel to the second ventilation direction F2 to accelerate heat dissipation through the ventilation channel 10a in the second ventilation direction F2.
[0032] In this way, the heat generated by the optical component 110 of the first optical module is dissipated through the first heat dissipation channel of its needle-shaped heat dissipation structure, and the heat dissipation is accelerated through the ventilation channel 10a with the first ventilation direction F1 corresponding thereto; the heat generated by the optical component 110 of the second optical module is dissipated through the second heat dissipation channel of its needle-shaped heat dissipation structure, and the heat dissipation is accelerated through the ventilation channel 10a with the second ventilation direction F2 corresponding thereto, thereby completing the effective heat dissipation of the two optical modules.
[0033] In some specific embodiments, when the first optical module 11 and the second optical module 12 are arranged, the optical component 110 and the heat dissipation component 111 of the first optical module 11 are arranged along the first ventilation direction F1, and the optical component 110 and the heat dissipation component 111 of the second optical module 12 are also arranged along the first ventilation direction F1; the heat dissipation component 111 of the first optical module 11 is communicated with the ventilation channel 10a with the first ventilation direction F1, and the first optical module 11 is cooled through the ventilation channel 10a with the first ventilation direction F1. The heat dissipation component 111 of the second optical module 12 is communicated with the ventilation channel 10a with the second ventilation direction F2, and the second optical module 12 is cooled through the ventilation channel 10a with the second ventilation direction F2.
[0034] Moreover, the first optical module 11 and the second optical module 12 are staggered in the first ventilation direction F1, and the staggering distance is determined based on the length of the ventilation channel 10a having the first ventilation direction F1 in the first ventilation direction F1. For example, the first optical module 11 and the second optical module 12 are staggered in the first ventilation direction F1, and the staggering distance is greater than the length of the ventilation channel 10a having the first ventilation direction F1 in the first ventilation direction F1. In this way, when the heat dissipation component 111 of the first optical module 11 corresponds to and communicates with the ventilation channel 10a in the first ventilation direction F1, the heat dissipation component 111 of the second optical module 12 can correspond to and communicate with the ventilation channel 10a in the second ventilation direction F2.
[0035] In the optical module, since heat is mainly generated by the light source when the optical component 110 operates, the heat dissipation component 111 is located on the side of the optical component 110 where the light source is provided, and the ventilation channel 10a of the ventilation component 10 corresponds to the heat dissipation component 111 to facilitate heat dissipation of the light source.
[0036] In this application, the first optical module 11 and the second optical module 12 are arranged side by side and staggered in the first ventilation direction F1, that is, the first optical module 11 and the second optical module 12 are arranged side by side along the Figure 1 left - right direction (the second ventilation direction F2) as shown, and are staggered along the front - back direction (the first ventilation direction F1). In the first ventilation direction, the first optical module 11 is arranged in the front and the second optical module 12 is arranged in the back. The ventilation component 10 is exactly located in the space where the two are staggered front and back. In this way, one ventilation channel 10a of the ventilation component 10 can correspond to the first optical module 11 front and back, and the other ventilation channel 10a of the ventilation component 10 corresponds to the second optical module 12 left and right, so as to dissipate heat from the first optical module 11 and the second optical module 12 simultaneously through the same ventilation component 10.
[0037] Such a layout makes the two ventilation channels 10a arranged in an Figure 3 L - shape as shown, which can ventilate in two directions to correspond to the first optical module 11 and the second optical module 12, thereby achieving efficient heat dissipation.
[0038] For the ventilation component 10, it includes at least a first air duct bracket 101 and a second air duct bracket 102. The first air duct bracket 101 and the second air duct bracket 102 are relatively buckled to form the ventilation channel 10a. The ventilation component 10 includes a fan component 103 arranged at the connection of at least two ventilation channels 10a, and the fan component 103 communicates with the ventilation channel 10a.
[0039] Such as Figure 2As shown in the figure, both the first air duct bracket 101 and the second air duct bracket 102 are shell structures with an opening on one side. After the openings of the first air duct bracket 101 and the second air duct bracket 102 are butted and fastened, a ventilation channel 10a can be formed at the end position. The fan component 103 is located at the middle position after being fastened. The ventilation channel 10a is formed around the fan component 103. The fan component 103 is fixed to the first air duct bracket 101 by screws. When the heat dissipation component 111 transfers the heat of the optical component 110 to the ventilation channel 10a, the fan component 103 is then used to extract the heat from the ventilation channel 10a to accelerate the heat dissipation speed.
[0040] In addition, the first air duct bracket 101 and the second air duct bracket 102 are snap-connected by a plurality of snap fasteners. The plurality of snap fasteners are circumferentially arranged on the circumferential wall of the first air duct bracket 101 or the second air duct bracket 102.
[0041] Generally, the snap fastener cooperates with a card slot for snap-fitting. When the snap fastener is arranged on the first air duct bracket 101, the card slot is arranged on the second air duct bracket 102; when the snap fastener is arranged on the second air duct bracket 102, the card slot is arranged on the first air duct bracket 101.
[0042] Taking the snap fastener arranged on the first air duct bracket 101 as an example, the plurality of snap fasteners are circumferentially arranged in a circle along the circumferential wall of the first air duct bracket 101, and the card slots are adaptively arranged on the second air duct bracket 102, so that the first air duct bracket 101 and the second air duct bracket 102 can be stably snap-connected. The snap-connection setting method is convenient for quick disassembly and assembly, and improves the efficiency of assembly and maintenance.
[0043] Further, referring to Figure 4 , the headlight device further includes a bracket 13, and the ventilation component 10 and at least two optical modules are both arranged on the bracket 13.
[0044] Generally, a fulcrum is arranged on the bracket 13, and the fulcrum can be adjusted in position on the bracket 13. The ventilation component 10 and the optical module are both arranged on the fulcrum of the bracket 13. In this way, the positions of the ventilation component 10 and the optical module on the bracket 13 can be changed by adjusting the position of the fulcrum to realize the simultaneous dimming of at least two optical modules. The specific structure and principle can refer to the prior art and will not be elaborated here.
[0045] In this application, two optical modules are taken as an example. When there are three or more optical modules, the above settings can be referred to.
[0046] In summary, for the headlight device provided in the embodiment of the present application, the cooperation between the needle-shaped heat dissipation structure of the heat dissipation component 111 in the optical module and the ventilation channel 10a enables efficient heat dissipation of at least two optical modules through the same ventilation component 10. The ventilation component 10 has at least two ventilation channels 10a. At least two optical modules are arranged on one side of at least two ventilation channels 10a in a one-to-one correspondence. The optical component 110 is cooled by the needle-shaped heat dissipation structure, and the ventilation component 10 is used to accelerate heat dissipation, improving the heat dissipation efficiency. The layout of the ventilation component 10 and the optical module reduces space occupation and solves the problems of heat dissipation requirements and space occupation of traditional multi-modules.
