In the embodiment of the present invention, referring to fig. 1, 3 and 4, the AR glasses include a front frame 10, a first temple 20, a second temple 40 and a liquid cooling tube 50, wherein the front frame 10 is provided with a first inner cavity 10 a; one end of the first glasses leg 20 is rotatably connected with one end of the front glasses frame 10; the first temple 20 is provided with a second inner cavity 20a, the second inner cavity 20a is communicated with the first inner cavity 10a, and the chip 30 is installed in the second inner cavity 20 a; one end of the second temple 40 is rotatably connected with one end of the front frame 10 far away from the first temple 20; the second temple 40 is provided with a third inner cavity 40a, and the third inner cavity 40a is communicated with the first inner cavity 10 a; the liquid cooling pipe 50 is sequentially arranged on the first leg 20, the front frame 10 and the second leg 40 in a penetrating manner and is positioned in the third inner cavity 40a, the first inner cavity 10a and the second inner cavity 20 a; and the liquid cooling tube 50 is connected to the chip 30.

In this embodiment, in view of the fact that the liquid cooling tube 50 sequentially penetrates through the first leg 20, the front frame 10 and the second leg 40, the liquid cooling tube 50 penetrates through the first inner cavity 10a, the second inner cavity 20a and the third inner cavity 40a, so that the liquid cooling tube 50 can form a complete and continuous heat dissipation path among the first leg 20, the second leg 40 and the front frame 10, and heat dissipated by the chip 30 is spread in the first leg 20, the front frame 10 and the second leg 40 by water flow, which not only reduces the use of the graphite sheet spanning the rotation axis, but also improves the heat dissipation efficiency.

When the AR glasses are normally operated, the first and

second temples

20 and 40 are spread, and the liquid-cooling tube 50 is also spread. After AR glasses used a period of time, the chip 30 of third inner chamber 40a can generate heat and produce certain heat, and the heat is absorbed by the water in liquid cooling pipe 50 after leading into liquid cooling pipe 50, because the density and the specific heat capacity of water are great, under the same volume and the temperature rise condition, the ability of water absorbed heat is 3200 times of air, can guarantee that the inside temperature of AR glasses can not overtemperature in longer time. The heat is not isolated in the second inner cavity 20a or the third inner cavity 40a by the rotating shaft between the front frame 10 and the first leg 20 and the rotating shaft between the front frame 10 and the second leg 40, and the heat is diffused from the third inner cavity 40a to the second inner cavity 20a and the first inner cavity 10a through the liquid cooling tube 50 connected with the chip 30, so that the heat is not independently accumulated in the second inner cavity 20a or the third inner cavity 40a, the problem of uniform distribution of the heat in the AR glasses is solved, the heat dissipation paths of the first leg 20, the second leg 40 and the front frame 10 are continuous, and the heat dissipation area is greatly increased; and the heat emitted by the chip 30 is transferred to the liquid in the liquid cooling tube 50, and the flowing speed of the liquid is higher than that of the air, so that the heat dissipation speed of the AR glasses is increased.
