[0036] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0037] Please refer to Figures 1-6 , a 360-degree light-emitting vehicle lamp, comprising:

[0038] A plug 100, including a base 110 and a plurality of pins 120 provided on the base 110;

[0039] A circuit board 200, connected to the side of the base 110 facing away from the pins 120;

[0040] A fan assembly 300, including an axial flow fan 310 and a micro motor 320 for driving the axial flow fan 310;

[0041] The mounting housing 400 is provided with a plug mounting portion 410, a first accommodation cavity 420, a second accommodation cavity 430, and a third accommodation cavity 440 in sequence from bottom to top. The base 110 is connected to the plug mounting portion 410, and the pins 120 extend outside the mounting housing 400. The circuit board 200 is assembled in the first accommodation cavity 420, and the fan assembly 300 is limit-assembled in the second accommodation cavity 430. A plurality of air inlet holes 450 are provided in the first accommodation cavity 420 and / or the second accommodation cavity 430;

[0042] The radiator 500 is limit-assembled in the third accommodation cavity 440, and a mounting hole 510 is provided at the center of the radiator 500;

[0043] The lamp post 600 is fixed in the mounting hole 510 and extends outside the mounting housing 400. The lamp post 600 is made of a heat-conducting material, and a plurality of lamp beads 610 are provided on the lamp post 600. The lamp beads 610, the plug 100, and the micro motor 320 are all electrically connected to the circuit board 200.

[0044] The lamp post 600 is located outside the mounting housing 400 and has sufficient heat dissipation space, so that heat is not easily accumulated. The heat generated by the lamp beads 610 is transferred to the radiator 500 through the lamp post 600. Under the active heat dissipation of the fan assembly 300, the axial air flow takes away the heat on the radiator 500 and the lamp post 600, thereby improving the heat dissipation effect.

[0045] Please refer to Figure 2 , a wind hood 460 is formed on the outer wall of the mounting housing 400. The wind hood 460 opens downward, and the air inlet holes 450 are provided below the wind hood 460. The wind hood 460 is provided to prevent the high-temperature air flow blown out from the mounting housing 400 from returning to the mounting housing 400 again, thereby ensuring the heat dissipation effect.

[0046] Please refer to Figure 1 and Figure 2 , the wind hood 460 horizontally extends outward with a flange 461, and the flange 461 horizontally extends outward with a plurality of limiting grooves 462 and extension plates 463. It is convenient for the installation and connection of the vehicle lamp and other devices.

[0047] Preferably, the top height of the wind hood 460 is higher than the bottom of the fan assembly 300 and lower than the top of the fan assembly 300; the bottom height of the wind hood 460 is higher than the middle of the air inlet holes 450 and lower than the bottom of the fan assembly 300. Ensure the inlet air flow, thereby ensuring the heat dissipation effect.

[0048] Please refer to Figure 3 and Figure 6, the fan assembly 300 further includes a mounting bracket 330. The mounting bracket 330 includes a cylindrical wall 331 and a bracket 332. The bracket 332 is connected to one end inside the cylindrical wall 331. The micro motor 320 is fixed on the bracket 332. The axial flow fan 310 is connected to the output shaft of the micro motor 320 and is located inside the cylindrical wall 331. The rotation of the axial flow fan 310 can be prevented from being disturbed by the mounting bracket 330.

[0049] Please refer to Figure 1 and Figure 2 , the lamp post 600 further includes a lamp cap 620. The lamp cap 620 wraps the top of the lamp post 600 and extends downward to form a light guiding arc plate 621. The lamp cap 620 is provided to protect the lamp beads 610, and the light guiding arc plate 621 can also conduct light, adjust the light, and improve the lighting effect. It can be understood that in order to ensure 360-degree light emission of the vehicle lamp, the light guiding arc plate 621 only covers a part of the lamp beads 610 in the height direction, and still a part of the lamp beads 610 are exposed.

[0050] Preferably, the base 110 and the circuit board 200 are integrally connected by welding or gluing. This facilitates the installation of the circuit board 200 and prevents the circuit board 200 from being disturbed and vibrated by the air flow.

[0051] Furthermore, the plug mounting portion 410 is a mounting groove. The base 110 is provided with a convex portion adapted to the mounting groove. The mounting groove is further provided with a first horizontal rotation limiting portion 411, and the convex portion is provided with a second horizontal rotation limiting portion 111 nested with the first horizontal rotation limiting portion 411. Briefly, one of the first horizontal rotation limiting portion 411 and the second horizontal rotation limiting portion 111 is a convex block, and the other is a groove adapted to the convex block.

[0052] Please refer to Figure 3 and Figure 5 , inside the mounting housing 400, a wind deflector 470 is further provided below the air inlet hole 450. The wind deflector 470 is provided with a wire passing hole 471. The wind deflector 470 is provided to reduce the influence of the air flow on the circuit board 200.

[0053] Please refer to Figure 5 and Figure 6 , the mounting housing 400 includes a left housing 480 and a right housing 490. The left housing 480 and the right housing 490 are detachably connected. Generally, the left housing 480 is connected by screws or bolts, and can be assisted by a positioning structure.

[0054] Particularly, the bottom of the lamp post 600 is tightly fitted or welded to the mounting hole 510. The mounting hole 510 has a wire hole channel for the cable to pass through, so as to electrically connect the lamp beads 610 and the circuit board 200.

[0055] Preferably, the lamp post 600 is made of metal or alloy material.

[0056] It is understandable that the radiator 500 is composed of a central cylinder forming the mounting holes 510 and several heat dissipation fins arranged in an annular array on the central cylinder. The radiator 500 is generally made of materials such as cast iron, steel, copper, and copper-aluminum alloy.

[0057] It is understandable that the lamp beads 610 are arranged on the lamp post 600 in four, six, or eight sides to form 360-degree light emission. At the same time, the cross-section of the lamp post 600 where the lamp beads 610 are installed is also a regular quadrilateral, regular hexagon, or regular octagon.

[0058] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0059] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0060] In summary, the 360-degree light-emitting vehicle lamp provided by the present invention has the lamp post located outside the mounting housing, with sufficient heat dissipation space, and heat is not easily accumulated. The heat generated by the lamp beads is transferred to the radiator through the lamp post, and the axial air flow takes away the heat on the radiator and the lamp post under the active heat dissipation of the fan assembly, thereby improving the heat dissipation effect.

[0061] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the present invention.
