The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a preferred embodiment of the present invention provides a vehicle lamp with a heat dissipation structure convenient to replace, including a wind tunnel 2 and a fan 3 disposed on a lamp housing 1, wherein the fan 3 is fixedly disposed on the outer side of the lamp housing 1, the air outlet direction of the fan 3 is aligned to the inner portion of the lamp housing, and the air outlet of the fan 3 is located in the region enclosed by the wind tunnel 2. After the fan 3 is fixed on the lampshade outer shell through screws, the heat dissipation part can be directly dissipated through the fan 3. When the mounting position of the heat dissipation part is greatly deviated from the blowing direction of the fan 3, the air duct 6 with different air guide structures mounted inside the lampshade shell 1 can guide the air from the air outlet of the fan 3 to the position with the heat dissipation part, and meanwhile, the air duct 6 can also play a role of collecting the air force, so that the blowing of the air to the ineffective area is reduced.

As shown in fig. 4, an enclosure plate 4 is fixedly connected to the outer side of the lampshade case 1, the fan 3 is located in an enclosure space enclosed by the enclosure plate 4, and a sealing cover 5 is fixedly arranged at one end of an opening of the enclosure plate 4. The enclosure plate 4 is a cylindrical shell with a certain draft angle, i.e. a structure with a flaring shape, so that when the back-off ring 52 of the sealing cover 5 is buckled and covered outside the enclosure plate 4, the sealing cover 5 can be prevented from falling off, and the sealing cover 5 is made of a material with certain elasticity, such as rubber. The sealing cover 5 comprises a reinforcing cap 51 and a back-off ring 52 fixedly connected to the edge of the reinforcing cap 51, the reinforcing cap 51 and the back-off ring 52 are integrally formed, the reinforcing cap 51 is arranged into a circular truncated cone-shaped shell structure, the strength of the whole sealing cover 5 is increased by arranging the reinforcing cap 51, and the sealing cover 5 is prevented from deforming due to the change of internal pressure after the fan 3 is opened. The retaining ring 52 is fixedly fastened to the outside of the apron 4, and can be firmly bound to the outside of the apron 4 due to its elasticity.

As shown in fig. 1 and 2, a plurality of positioning posts 11 and screw posts 12 are fixedly disposed on the outer side of the lamp cover housing 1 for mounting and fixing the fan 3. The positioning posts 11 are used to ensure the accuracy of the installation posture of the fan 3, and the screw posts 12 are used to install screws to fix the fan 3.

As shown in fig. 4, the fan 3 is disposed in an installation space enclosed by the enclosure plate 4 and the sealing cover 5, which can provide protection for the fan 3 on one hand, and can also provide a sealed space on the other hand, so as to ensure the sealing performance inside the lamp housing 1 after the fan 3 is installed. In order to reduce the size of the lamp housing after the fan 3 is installed at the outside, the position of the lamp housing 1 for installing the fan 3 may be set to a concave type seating groove structure, and the part of the structure is recessed inside the lamp housing, so that the change of the external size can be reduced.

As shown in fig. 4, a snap ring 7 is fixedly disposed on the inner side of the lamp shade housing 1, and the end section of the air duct 6 is fixedly sleeved inside the snap ring 7, and the two can be fixed by interference fit, or can be fixed by an existing connection method, such as adhesion, thread connection, and the like.

The outside of lamp shade casing 1 is fixed and is provided with outer fender ring 8, outer fender ring 8 arranges and plays the guard action around apron 4.

The working principle is as follows:

when the fan 3 needs to be replaced, the sealing cover 5 is firstly removed, and then the fan 3 fixed in the enclosure space is detached to replace the new fan 3, so that the damaged fan 3 can be replaced. And after the replacement is finished, the sealing cover 5 is covered.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
