Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

As shown in fig. 1-2, the first embodiment provides a lens assembly, which includes a lens barrel 1 and a lens body 2, wherein an annular protrusion 3 protrudes inward from an inner wall of the lens barrel 1, the lens body 2 is disposed in the lens barrel 1 and disposed on the annular protrusion 3, a first gap 4 is disposed between a contact surface of the lens body 2 and the annular protrusion 3, the first gap 4 is used for external air flow to pass through, a second gap 5 is disposed between a side edge of the lens body 2 and the inner wall of the lens barrel 1, and the air flow passing through the first gap 4 enters the lens barrel 1 through the second gap 5.

In the above technical scheme, the first gap 4 and the second gap 5 form an air circulation channel between the inside of the lens and the outside, so that the heat dissipation effect of the lens can be effectively improved, and the lens has a simple structure, is beneficial to processing and manufacturing, and is low in processing cost.

As shown in fig. 2, the contact surface of the annular protrusion 3 and the mirror body 2 is provided with a groove 6 in a wave shape along the circumferential direction to form a first gap 4.

Further, the inner wall of the groove 6 is inclined towards the center from the outside of the lens barrel 1, so that the opening size of one side of the groove 6, which is located in the external environment, is larger, and the airflow enters the lens barrel 1 through one side with a larger opening, because the space of the groove 6 is gradually reduced, therefore, the groove 6 has a certain acceleration effect, the kinetic energy of the airflow entering the lens barrel 1 can be improved, the heat dissipation effect is improved, the acceleration effect of the airflow can be utilized to impact the dust in the groove 6, and the groove 6 is prevented from being blocked by the dust.
