Description

Technical Field

[0001] The present invention relates to a smart wearable device, and in particular to smart glasses. Background Art

[0002] Smart glasses are a general term for wearable glasses that have an independent operating system like a smartphone and can realize various functions through software installation. Smart glasses are one of the most promising wearable smart devices proposed in recent years, with the characteristics of easy use and small size.

[0003] The structure of smart glasses generally includes: a lens frame that can be placed horizontally above the bridge of the nose, temples rotatably connected to the lens frame, a wide strip host located on the outside of the temples, a display screen located at the front end of the lens, a speaker inside the host shell, and a camera outside the lens frame.

[0004] During the use of smart glasses, the host, speaker, and camera fill light will generate heat. The shell of the existing speaker is generally made of plastic material and ultrasonically welded, and does not have a heat dissipation function. The existing heat dissipation solution for the host is to directly conduct the heat to the host shell by adding thermal conductive silicone grease on both sides of the host. This solution can only allow the heat to be directly conducted to the host shell and contact the air, and cannot form a heat conduction gradient difference, resulting in a higher touch temperature of the host shell. The camera's fill light is installed in a small space and will also generate a lot of heat during use, so a heat dissipation solution also needs to be designed.

[0005] In addition, if Figure 1 As shown, the temple is movably connected to the lens frame through a rotating shaft, a locking screw is provided at one end of the rotating shaft, a rotating sleeve is sleeved on the outside of the rotating shaft, and the rotating sleeve is connected to the temple; since the rotating sleeve is not in contact with the mounting seat of the lens frame, the temple cannot be stopped at any angle; when the temple rotates, the friction caused by the rotating sleeve on the locking screw may cause the screw to loosen, affecting the rotation effect. Summary of the invention

[0006] The purpose of the present invention is to provide a pair of smart glasses with a heat dissipation function in order to solve the heat dissipation problem of smart glasses during use.

[0007] The technical solution of the present invention is: a pair of smart glasses with heat dissipation function, which includes: a lens frame, temples, a host, a speaker, a camera device and a display screen;

[0008] The speaker includes: an aluminum alloy upper cover, a speaker and a plastic lower cover; the speaker is installed in the plastic lower cover through a Mylar sheet; the aluminum alloy upper cover and the plastic lower cover are sealed by foam and then tightened and fixed by screws;

[0009] The host comprises: a main shell consisting of a left shell and a right shell, and a left heat sink, a right heat sink, a copper-aluminum heat sink, a mainboard, a first thermally conductive silicone, a second thermally conductive silicone and a heat sink connecting plate arranged in the main shell; wherein the left heat sink is attached to the inner wall of the left shell, and the right heat sink is attached to the right shell; the speaker is arranged in the main shell and is electrically connected to the mainboard; the first thermally conductive silicone and the second thermally conductive silicone are arranged on both sides of the mainboard; the substrate of the copper-aluminum heat sink is made of aluminum, and copper parallel ribs are arranged on the substrate; the copper-aluminum heat sink is arranged between the left shell and the mainboard, and its substrate is attached to the mainboard through the first thermally conductive silicone; the heat sink connecting plate connects the speaker and the copper-aluminum heat sink;

[0010] The camera device includes: a camera, a fill light LED, a third thermal conductive silicone, copper foil and heat dissipation graphite; the fill light LED is installed on one side of the camera, and the light-emitting end face of the fill light LED is attached to the copper foil through the third thermal conductive silicone; the heat dissipation graphite is arranged on the outside of the fill light LED; the camera device is installed at the front end of the host.

[0011] Furthermore, on the basis of the above scheme, in order to stop the temple from rotating at any angle, the temple is connected to the lens frame through a rotating shaft, a rotating sleeve, a locking screw and a damping gasket; wherein one end of the rotating shaft is inserted into the mounting seat of the lens frame, and the other end is provided with a locking screw; the rotating sleeve is sleeved on the rotating shaft, and the two ends of the rotating sleeve are respectively in contact with the mounting seat and the locking screw of the lens frame through the damping gasket; the temple is connected to the rotating sleeve. When the locking screw is tightened, the rotating sleeve generates friction with the lens frame through the damping gasket to form resistance, so that the temple can stop rotating at any angle.

[0012] Furthermore, on the basis of the above scheme, in order to prevent the locking screw from loosening, the temple is connected to the lens frame through a rotating shaft, a rotating sleeve, a locking screw and a locking washer; wherein one end of the rotating shaft is inserted into the mounting seat of the lens frame, and the other end is provided with a polygonal protrusion; the locking washer is provided with a polygonal hole matching the polygonal protrusion; the locking washer is sleeved on the polygonal protrusion; the lower end face of the locking screw contacts the locking washer and is threadedly connected to the rotating shaft; the rotating sleeve is sleeved on the rotating shaft; and the temple is connected to the rotating sleeve. When the temple rotates, the rotating sleeve will only contact the locking washer and will not contact the locking screw, thereby preventing the screw from loosening.

[0013] Beneficial effects: The present invention changes the material of the upper cover of the speaker to aluminum alloy, and adds a copper-aluminum heat sink in the shell of the host, thereby changing the thermal conductivity coefficient, and increasing the heat transfer gradient difference of the heat sink in the shell of the host, so as to achieve a suitable body temperature of the shell of the host; the fill light LED of the camera device is added with thermal grease and copper foil, and the thermal grease is used to fill the surrounding space, and the copper foil is used to increase the heat dissipation area. Heat dissipation graphite is provided between the fill light LED and the shell of the host to achieve a cooling effect. The present invention also provides a solution for realizing the rotation of the temples at any angle and preventing the shaft screws from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
