[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The core of the present invention is to provide a smart glasses cooling structure with good heat dissipation performance.

[0035] For a specific embodiment of the cooling structure of smart glasses provided by the present invention, please refer to Figures 1 to 6 , comprising a frame 1 and a temple 2 hinged to the end of the frame 1 through a rotating shaft 6, and a temple cavity 7 is provided in at least one temple 2. When applied to smart glasses (specifically AR glasses), a temple control component, such as a temple PCB 71, is installed in the temple cavity 7, which is electrically connected to the main control component in the frame cavity 5 for data exchange. During operation, the temple control component generates heat.

[0036] The temple cavity 7 is communicated with the frame cavity 5 of the frame 1 through the shaft cavity 61 of the shaft 6. Usually, the inner cavity of the glasses formed by the frame cavity 5, the shaft cavity 61 and the temple cavity 7 is a sealed cavity to ensure waterproof performance.

[0037] like Figure 5As shown, a fan 3 is provided in the frame cavity 5 near the shaft cavity 61, and the fan 3 is used to drive the airflow from the temple cavity 7 to flow into the frame cavity 5. In addition, the fan 3 is electrically connected to the main control component in the frame cavity 5 to start and stop according to the signal controller of the main control component.

[0038] The smart glasses include two temples 2. In this embodiment, only one temple 2 is provided with a temple cavity 7, and accordingly, a fan 3 is provided in a portion of the frame cavity 5 close to the temple 2. The other temple 2 does not have a temple cavity 7, and accordingly, a fan 3 may not be provided in a portion of the frame cavity 5 close to the temple 2. Of course, in other embodiments, temple cavities 7 may be provided in both temples 2, and the number of fans 3 is not limited to one, and two or more fans may also be provided.

[0039] In the present embodiment, the heat in the temple cavity 7 can be drawn into the frame cavity 5 by the fan 3 through the shaft cavity 61, and heat transfer is achieved by thermal convection. This can improve the heat transfer efficiency near the shaft 6, and there is no need to set a graphite sheet across the shaft for heat conduction, which is beneficial to reducing costs and facilitating the assembly of the equipment. At the same time, the fan 3 can disturb the airflow in the frame cavity 5, and evenly spread the hot air in the airflow in the frame cavity 5, indirectly increasing the heat dissipation area, which can effectively improve the heat dissipation efficiency and have good heat dissipation performance.

[0040] Furthermore, if Figure 3 As shown, the smart glasses cooling structure further includes a heat dissipation bar 4 disposed in the frame cavity 5, and a portion of the heat dissipation bar 4 is attached to the air outlet 32 ​​of the fan 3. With the help of solid heat dissipation, the heat dissipation efficiency at the air outlet 32 ​​can be improved.

[0041] Furthermore, if Figure 3 As shown, part of the structure of the heat dissipation strip 4 is attached to the inner wall of the frame cavity 5, and the heat of the air outlet 32 ​​can be quickly transferred to the frame 1 by means of the heat dissipation of the heat dissipation strip 4, so as to quickly dissipate the heat outwards by means of the frame 1.

[0042] Furthermore, if Figure 2 and Figure 3 As shown, the heat sink 4 includes a heat sink 42 and a heat pipe 41. The heat sink 42 is fitted to the air outlet 32, and optionally, the heat sink 42 is a graphite sheet. One end of the heat pipe 41 is fixed to the heat sink 42, specifically by welding, and the rest of the heat pipe 41 is extended in a set direction in the frame cavity 5, and the set direction extension can be set as needed. By setting the heat pipe 41, the heat dissipation performance of the heat sink 4 can be ensured. Of course, in other embodiments, the heat sink 4 can also be directly set as a graphite sheet.

[0043] Furthermore, if Figure 3As shown, the heat dissipation strip 4 extends from one end of the frame cavity 5 toward the other end, that is, in the frame cavity 5, the heat dissipation strip 4 can transfer heat from the direction close to one temple 2 toward the direction close to the other temple 2, specifically, from the end where the fan 3 is set toward the end where the fan 3 is not set, and the solid thermal conductivity of the heat dissipation strip 4 can be used to improve the uniformity of heat distribution in the frame cavity 5.

[0044] Furthermore, a slot 12 is provided in the lens frame cavity 5, and the heat dissipation strip 4 is plugged into and matched with the slot 12. Figures 2 to 4 As shown, there is a bracket 11 in the lens frame cavity 5, and a slot 12 is arranged on the bracket 11. The heat pipe 41 includes a main body part 411 and a bent part 412 connected to the main body part 411. After the heat pipe 41 is plugged into the slot 12, the main body part 411 and the bent part 412 are respectively located on both sides of the slot 12, thereby realizing reliable plug-in and fixation of the heat pipe 41.

[0045] Furthermore, if Figure 6 As shown, the fan 3 is suspended in the lens frame cavity 5, that is, there is no direct connection between the fan 3 and the lens frame cavity 5, and the fan 3 is fixedly connected to the inner wall of the lens frame cavity 5 through the heat dissipation strip 4. The fan 3 is suspended. Since the heat dissipation strip 4 is originally to be connected to the inner wall of the lens frame cavity 5, the heat dissipation strip 4 is used as a connecting member to realize the connection between the fan 3 and the lens frame cavity 5, which is convenient for assembly. Of course, in other embodiments, the fan 3 and the lens frame cavity 5 can also be directly connected by welding or other methods.

[0046] Furthermore, if Figure 3 As shown, the frame cavity 5 includes a U-shaped cavity composed of a main cavity 51 and end cavities 52 respectively connected to the two ends of the main cavity 51. The main cavity 51 is connected to the end cavity 52. ​​The port of the end cavity 52 is connected to the rotating shaft 6. The fan is arranged in the end cavity 52 to facilitate the positioning and assembly of the fan 3.

[0047] Furthermore, if Figure 5 and Figure 6 As shown, the air outlet 32 ​​of the fan 3 faces the inner wall of the end chamber 52. Specifically, the end chamber 52 has two opposite ports, namely, an outer port 521 and an inner port 522. The outer port 521 is connected to the rotating shaft 6, the air inlet 31 of the fan 3 faces the outer port 521, and the inner port 522 is connected to the main chamber 51, and the inner wall of the end chamber 52 is the part between the two ports. Based on the setting of the direction of the air outlet 32 ​​in this embodiment, the hot air blown out by the fan 3 will not be blown directly to the main control components in the main chamber 51, so as to avoid affecting the operation of the main control components.

[0048] The cooling structure provided in this embodiment, when applied to smart glasses, works as follows: when the smart glasses are working normally, the temple 2 is unfolded, and the air inlet 31 of the fan 3 is facing the temple PCB 71 in the temple 2, with low impedance. The fan 3 uses the airflow to draw the heat in the temple cavity 7 into the frame cavity 5 across the rotating shaft 6; the heat drawn into the frame cavity 5 by the fan 3 is quickly spread in the frame cavity 5 by the heat sink 42 and the heat pipe 41, which can improve the heat dissipation efficiency; because the smart glasses are not designed with air inlets and outlets connected to the inner cavity of the eye for the purpose of waterproofing, the fan 3 can disturb the airflow in the smart glasses and evenly spread the hot air in the airflow in the frame cavity 5, thereby indirectly increasing the heat dissipation area and effectively improving the heat dissipation efficiency.
