Among them, the frame includes a frame for supporting the lens and two legs, and the legs are hinged to the frame, so that the frame has two states during daily use, namely, the open state when the glasses are worn and the folded state when the glasses are stored.

[0003] For the connection structure of the leg and the frame, in the prior art, a pile head is fixedly connected on the frame, a clamping groove is formed in the front end of the pile head, a movable column is arranged in the clamping groove, the end surface of the leg has a clamping hook, the clamping hook is inserted into the clamping groove and cooperates with the movable column, so that the leg rotates around the movable column, and the end surface of the leg is abutted against the front end of the pile head, so that the frame is kept in the open state. For example, a detachable and replaceable leg of a glasses frame is disclosed in Chinese patent document CN202222802563.5.

[0004] With the progress of science and technology, the glasses manufacturers implant intelligent modules, such as Bluetooth modules, in the legs, and the legs with Bluetooth modules are larger and heavier in size than traditional glasses, and have good structural stability, but at the same time, the legs cannot be adjusted according to the head circumference like traditional thin legs, which causes the legs to clamp the wearer's head, the head to spread the two legs, and the legs to be easily deformed after long-term wearing of the glasses, and poor wearing comfort. SUMMARY

[0005] The utility model aims at the above problems existing in the prior art, and provides a connection structure for Bluetooth glasses, which solves the technical problem of how to avoid the deformation of the legs after long-term wearing and improve the wearing comfort of the glasses.

[0006] The utility model can be realized by the following technical schemes:

[0007] A connection structure for Bluetooth glasses, the Bluetooth glasses including a frame and a leg, the connection structure including a pile head, characterized in that the pile head has a base fixedly connected to the inner side of the frame and a support block protruding relative to the inner side of the frame, the connection structure further including a spring hinge fixedly connected to the end of the leg, the spring hinge including a limiting part in the shape of a long strip and a telescopic hinge joint, the hinge joint being hinged to the support block, the limiting part protruding relative to the end surface of the leg and being arranged along the length direction of the leg, and when the end surface of the limiting part abuts against the base, the hinge joint extends out against the spring force to spread the leg outward, and the side surface of the limiting part can abut against the outer side of the support block.

[0008] The hinge joint of the spring hinge is hinged with the supporting block, the rotation of the hinge joint relative to the supporting block drives the rotation of the temple, the temple is not directly connected with the frame, the telescopic structure of the hinge joint expands the rotation range of the temple, the temple can continue to expand outward in the open state, the resistance between the temple and the head is minimized when the glasses are worn, the limiting portion protrudes relative to the end surface of the temple and is arranged along the length direction of the temple, the limiting portion is the extension of the length of the temple, the end surface of the limiting portion abuts against the base, the rotation of the hinge joint is supported by the position where the limiting portion abuts against the base, the base fixed to the inner side of the frame ensures the structural strength of the hinge joint, the side surface of the limiting portion abuts against the supporting block, the maximum rotation angle of the temple is determined, and the structural strength of the temple in the expanded state is ensured, thereby avoiding deformation of the temple after a long time, and improving the wearing comfort of the glasses.

[0009] In the connection structure for the Bluetooth glasses, the base is embedded in the inner side of the frame and protrudes relative to the inner side surface of the frame, the side of the base protruding from the frame has a guide surface inclined relative to the inner side surface of the frame, and the limiting portion moves along the guide surface when the temple expands outward. The position of the limiting portion changes when the temple expands outward, the inclined guide surface ensures the contact between the limiting portion and the base, ensures the stability of the temple in the expanded state, and avoids the friction between the limiting portion and the frame or the hard abutment between the limiting portion and the frame.

[0010] In the connection structure for the Bluetooth glasses, the supporting block is located on the guide surface and has a long block shape, the spring hinge further includes a main body portion having the hinge joint, the main body portion is fixed to the temple, the hinge joint extends out to make the temple in the open state when the inner side end corner of the supporting block abuts against the main body portion, and the limiting portion faces the outer side of the supporting block and the gap therebetween gradually decreases from the frame to the temple. The supporting block is arranged on the guide surface, so that the limiting portion can abut against the supporting block along the guide surface, the hinge joint is telescopic relative to the main body portion, the supporting block makes the hinge joint extend out relative to the main body portion when the temple is in the open state, the contact area of the supporting block on the main body portion is reduced, and the stability of the temple in the open state is ensured, and the gap between the limiting portion and the supporting block provides a space for the temple to expand outward.

[0011] In the connection structure for the Bluetooth glasses, the supporting block is inclined relative to the guide surface from the guide surface to the expansion direction of the temple, and the included angle between the outer side surface of the supporting block and the guide surface is an acute angle. The inclined arrangement of the supporting block increases the expansion range of the temple.

[0012] In the connection structure for the Bluetooth glasses, the length of the limiting portion protruding from the temple is greater than the length of the supporting block, and the end surface and the two side surfaces of the supporting block are smoothly connected. This structure minimizes the friction between the spring hinge and the hinge joint when the temple rotates, and makes the rotation of the temple relative to the frame smooth.

[0013] In the connecting structure for Bluetooth glasses, the width of the limiting part is greater than the height of the supporting block, and the end surface and the two side surfaces of the limiting part are smoothly transitioned. The structure makes the limiting part play a protective role on the supporting block, and ensures the contact area of the limiting part and the supporting block, and the support stability when the temple is in the outward expansion state. The smooth transition makes the rotation smooth when the temple is outwardly expanded, reduces the friction between the limiting part and the supporting block, and reduces the force required for the temple to be outwardly expanded, thereby improving the comfort of the glasses.

[0014] In the connecting structure for Bluetooth glasses, the pile head and the spring hinge are made of metal materials. The structure ensures the connection strength of the temple and the frame and the structural stability of the glasses when the glasses are opened.

[0015] Compared with the prior art, the connecting structure for Bluetooth glasses has the following advantages: the spring hinge is fixed to the end of the temple, the rotating angle of the existing temple is increased by the hinge joint of the spring hinge and the pile head, and a limiting part is additionally arranged on the spring hinge, so that the rotation of the hinge joint is supported by the abutting of the limiting part and the pile head, so that the temple can be further outwardly expanded in the original open state, the retracting force of the hinge joint ensures the tension of the temple, improves the inclusiveness of the glasses for different head circumferences, avoids deformation of the temple after long-term use, and improves the wearing comfort.
