[0046] This embodiment provides a pair of glasses, such as AR glasses, XR glasses and other smart glasses. Figure 1 and Figure 2 The glasses include two frame monomers 100. The frame monomer 100 includes a frame body 110 and a lens 120, and the lens 120 is fixedly arranged on the frame body 110. A nose pad 130 is fixedly arranged on the frame body 110 to facilitate wearing of the glasses.

[0047] The glasses include a connector 400, which is rotatably disposed between two frame monomers 100, that is, the two frame monomers 100 are rotatably disposed at opposite ends of the connector 400. One end of the connector 400 is rotatably connected to one of the frame bodies 110 through a rotating shaft or other components, and the other end of the connector 400 is rotatably connected to the other frame body 110 through a rotating shaft or other components.

[0048] The frame body 110 is rotated relative to the connecting body 400 to achieve folding and storage of the frame unit 100 .

[0049] The glasses include two temples 200. The two temples 200 are arranged in a one-to-one correspondence with the two frame monomers 100. One of the temples 200 is rotatably connected to one of the frame bodies 110, and the other temple 200 is rotatably connected to the other frame body 110. The temples 200 are folded and stored by rotating the temples 200 relative to the frame body 110.

[0050] The temple portion 200 includes a first temple 210. The first temple 210 is rotatably connected to the corresponding frame monomer 100. Specifically, one end of the first temple 210 is rotatably connected to the frame body 110 via a torsion spring and a rotating shaft. The first temple 210 can rotate relative to the frame body 110.

[0051] The temple portion 200 includes a second temple 220. The first temple 210 is slidably connected to the second temple 220. The second temple 220 extends or retracts along the length direction of the first temple 210.

[0052] The second temple 220 extends along the length direction of the first temple 210. The second temple 220 extends beyond the first temple 210, and the temple portion 200 is in an extended state. The temple portion 200 is longer at this time, which is convenient for wearing glasses. Figure 1 shown.

[0053] The second temple 220 is retracted along the length direction of the first temple 210, and the second temple 220 and the first temple 210 at least partially overlap, and the temple portion 200 is in a retracted state. At this time, the temple portion 200 is shorter in length and smaller in size, and is easy to store. Figure 2 shown.

[0054] The glasses further include a locking portion 300 . Figure 3 and Figure 4 3 is a schematic diagram of the locking portion 300. The locking portion 300 is configured to lock the temple portion 200 in a folded state in which the second temple 220 is retracted to the first temple 210 and the first temple 210 is abutted against the frame monomer 100. Figure 2 shown.

[0055] In other words, when the temple portion 200 is in a folded state, the second temple 220 is retracted into the first temple 210, and the first temple 210 rotates toward the inner side of the frame body 110, where the "inner side" refers to the side of the frame body 110 close to the wearer's face.

[0056] In the glasses of this embodiment, the frame monomer 100 rotates relative to the connecting body 400 to realize the folding of the frame monomer 100, and the first temple 210 rotates relative to the frame body 110 to realize the folding of the temple portion 200. At the same time, the second temple 220 retracts into the first temple 210 to reduce the length of the temple portion 200. In this way, the frame monomer 100 and the temple portion 200 are folded, effectively reducing the volume of the glasses after folding, which is convenient for carrying. Figure 1 As shown, the two frame monomers 100 are rotated to opposite ends of the connector 400, the temples 200 are rotated to a position substantially perpendicular to the frame monomers 100, and the second temples 220 extend from the first temples 210, and the glasses can be worn.

[0057] When the glasses in this embodiment need to be folded and carried, Figure 2 As shown, the frame monomer 100 is rotated from the end of the connecting body 400 to the side of the connecting body 400, the two frame monomers 100 are folded, the second temple 220 is retracted into the first temple 210, the length of the temple portion 200 is shortened, the first temple 210 is rotated and folded toward the inner side of the frame body 110, and the locking portion 300 locks the temple portion 200 in the folded state. The overall volume of the folded glasses is small and easy to carry.

[0058] In some embodiments, reference Figure 2 After the two frame monomers 100 are folded, the frame monomers 100 and the connector 400 are perpendicular to each other. After the two frame monomers 100 are folded, they are parallel to each other, and the space between them accommodates the two folded temple parts 200.

[0059] The extension width of the connecting body 400 in the horizontal direction should not be less than the total width of the two temple portions 200 after folding, so as to provide sufficient accommodation space for the two temple portions 200 .

[0060] In some embodiments, the two frame monomers 100 are rotated toward the inner side of the connecting body 400 to be folded. The volume of the two frame monomers 100 after folding is small, such as Figure 2 shown.

[0061] In some embodiments, the temple portion 200 rotates toward the inside of the frame monomer 100 for folding, that is, the first temple 210 rotates toward the inside of the frame monomer 100. After the two frame monomers 100 rotate and fold toward the inside of the connector 400, the gap between the two provides space for the temple portion 200 to be folded and stored.

[0062] The locking portion 300 is fixedly disposed on the inner side of the frame unit 100 so as to lock the folded temple portion 200 and lock the temple portion 200 in a folded state.

[0063] In some embodiments, the glasses are Figure 1 The expanded state shown is Figure 2 When the folding state is changed, the second temple 220 is first pushed into the first temple 210, the first temple 210 is rotated toward the inside of the frame body 110, the temple portion 200 is locked by the locking portion 300, and then the frame monomer 100 is rotated toward the inside of the connecting body 400. At this time, the temple portion 200 and the frame monomer 100 are both folded to obtain the following state: Figure 2 The folded posture shown is convenient for storage and carrying.

[0064] In some embodiments, the glasses are Figure 2 The folded state shown is Figure 1 When the unfolded state is changed, the frame monomer 100 is first rotated toward the side end of the connecting body 400 to unfold, the locking portion 300 releases the lock on the temple portion 200, and the temple portion 200 is rotated in a direction away from the frame monomer 100 until it is roughly perpendicular to the frame monomer 100, and then the second temple 220 is pulled outward from the first temple 210. At this time, the temple portion 200 and the frame monomer 100 are both unfolded to obtain the following state. Figure 1 Shown in the unfolded position for easy wearing.

[0065] In some embodiments, two locking portions 300 are provided, and a locking portion 300 is fixedly provided on the inner side of each frame body 110 . The two locking portions 300 correspond to the two temple portions 200 one by one, and each locking portion 300 is used to lock the corresponding temple portion 200 .

[0066] In some embodiments, a lock 230 is provided on the second temple 220. Figure 1 shown.

[0067] The locking portion 300 is as follows Figure 3 and Figure 4 The locking portion 300 includes a locking tongue 310. The locking tongue 310 is configured to cooperate with the locking port 230 to lock the temple portion 200 in the folded state. Figure 2 In the folded state shown, the locking tongue 310 is inserted into the locking opening 230 to lock the temple portion 200 in the folded state.

[0068] The locking portion 300 includes a driving portion 320 . The driving portion 320 is configured to drive the locking tongue 310 to move in a direction away from the locking port 230 to release the locking of the temple portion 200 .

[0069] When the temple 200 needs to be unfolded, the driving unit 320 drives the locking tongue 310 to move away from the locking port 230, and the locking tongue 310 disengages from the locking port 230 to release the locking of the temple 200. At this time, the temple 200 can rotate away from the frame unit 100.

[0070] In some embodiments, reference Figure 3 The driving unit 320 includes a hydraulic chamber 321 , which is fixedly disposed on the lens frame unit 100 , and a first end piston of the hydraulic chamber 321 is slidably connected to a first hydraulic rod 322 .

[0071] In a specific embodiment, the hydraulic chamber 321 is vertically arranged, and the bottom piston of the hydraulic chamber 321 is slidably connected to the first hydraulic rod 322 . The first hydraulic rod 322 can move up and down, that is, the first hydraulic rod 322 can move away from or close to the locking tongue 310 .

[0072] The locking part 300 includes a fixing body 330, which is fixedly mounted on the frame body 100 to achieve fixed mounting of the locking part 300 on the frame body 110. The fixing body 330 is provided with an installation cavity 331 and a first opening 332 and a second opening 333 communicating with the installation cavity 331.

[0073] The locking tongue 310 is slidably disposed in the first opening 332 , and the locking tongue 310 can move along the first opening 332 in a direction away from or close to the temple portion 200 .

[0074] When the locking tongue 310 moves toward the direction approaching the temple portion 200 , the locking tongue 310 can extend into the locking opening 230 to achieve folding locking of the temple portion 200 .

[0075] When the locking tongue 310 moves in a direction away from the temple portion 200 , the locking tongue 310 is separated from the locking port 230 , thereby releasing the locking of the temple portion 200 .

[0076] The first hydraulic rod 322 slides through the second opening 333 , and the first hydraulic rod 322 can move along the second opening 333 in a direction away from or close to the locking tongue 310 .

[0077] When the lock tongue 310 extends into the lock opening 230 , one end of the first hydraulic rod 322 cooperates with the lock tongue 310 to keep the lock tongue 310 in the lock opening 230 , preventing the lock tongue 310 from escaping from the lock opening 230 , thereby locking the lock tongue 310 .

[0078] When the first hydraulic rod 322 moves toward the direction approaching the locking tongue 310, one end of the first hydraulic rod 322 cooperates with the locking tongue 310 to drive the locking tongue 310 to move in the direction away from the locking port 230. In other words, when the locking portion 300 needs to release the locking of the temple portion 200, the first hydraulic rod 322 moves toward the direction approaching the locking tongue 310, and the first hydraulic rod 322 will drive the locking tongue 310 to move in the direction away from the locking port 230, and the locking tongue 310 will be separated from the locking port 230, thereby releasing the locking of the temple portion 200.

[0079] Figure 4The fixing body 330 is omitted in the illustrated structure so as to show the cooperation between the first hydraulic rod 322 and the locking tongue 310 .

[0080] In some embodiments, reference Figure 4 The first hydraulic rod 322 is provided with a first guide inclined surface 324 on a side facing the locking tongue 310 , and the locking tongue 310 is provided with a second guide inclined surface 312 on a side facing the first hydraulic rod 322 .

[0081] When the locking tongue 310 extends into the locking opening 230 , the first guiding inclined surface 324 abuts against the second guiding inclined surface 312 to limit the locking tongue 310 . At this time, the locking tongue 310 cannot move in a direction away from the locking opening 230 .

[0082] When the first hydraulic rod 322 moves toward a direction approaching the locking tongue 310 , the first guiding inclined surface 324 moves along the second guiding inclined surface 312 to drive the locking tongue 310 to move toward a direction away from the locking opening 230 .

[0083] by Figure 4 Taking the illustrated position as an example, the first hydraulic rod 322 moves downward, and the first guide slope 324 cooperates with the second guide slope 312 to cause the lock tongue 310 to move rightward, thereby causing the lock tongue 310 to disengage from the lock port 230 .

[0084] In some embodiments, the second end piston of the hydraulic chamber 321 is slidably connected to the second hydraulic rod 323 , and a pressing body 325 is fixedly provided at the end of the second hydraulic rod 323 . Pressing the pressing body 325 causes the first hydraulic rod 322 to move toward the direction close to the locking tongue 310 .

[0085] In a specific embodiment, the hydraulic chamber 321 is vertically arranged, and the top piston of the hydraulic chamber 321 is slidably connected to the second hydraulic rod 323. A pressing body 325 is fixedly arranged at the top of the second hydraulic rod 323 to facilitate the pressing operation.

[0086] When it is necessary to release the locking tongue 310 from locking the temple portion 200, refer to Figure 4 The user presses the pressing body 325 downward, the second hydraulic rod 323 moves downward, the liquid pressure in the hydraulic chamber 321 increases, and the first hydraulic rod 322 is squeezed to move downward. The first guide slope 324 and the second guide slope 312 cooperate to make the lock tongue 310 disengage from the lock port 230.

[0087] In some embodiments, a first elastic member 340 is disposed in the installation cavity 331. The first elastic member 340 is a spring, a spring, etc. The first elastic member 340 is disposed between the lock tongue 310 and the inner wall of the installation cavity 331. The first elastic member 340 is disposed on a side of the lock tongue 310 away from the lock port 230. The first elastic member 340 is configured to apply a force to the lock tongue 310 to move the lock tongue 310 toward the lock port 230.

[0088] Specifically, when the lock tongue 310 moves in a direction away from the lock opening 230, the first elastic member 340 is squeezed and contracted. When the lock tongue 310 faces the lock opening 230, the lock tongue 310 is pushed into the lock opening 230 under the rebound force of the first elastic member 340. At this time, the first hydraulic rod 322 is pushed by the second guide slope 312 to move in a direction away from the lock tongue 310 under the rebound force of the first elastic member 340.

[0089] In some embodiments, a guide arc surface 311 is disposed at one end of the locking tongue 310. The guide arc surface 311 is disposed at a side of the locking tongue 310 that is away from the frame body 110.

[0090] When the temple 200 is rotated and folded toward the inside of the frame body 110, the end of the second temple 220 first abuts against the guide arc surface 311. As the temple 200 continues to rotate inward, the locking tongue 310 is squeezed and moves first in a direction away from the temple 200, and the first elastic member 340 is squeezed and contracts. When the temple 200 is rotated until the locking tongue 310 is opposite to the locking port 230, the locking tongue 310 moves in a direction close to the locking port 230 under the rebound force of the first elastic member 340, and the locking tongue 310 extends into the locking port 230 to achieve locking of the temple 200.

[0091] The setting of the guiding arc surface 311 facilitates the locking tongue 310 to slide from the circumferential side of the second temple 220 to the side end of the second temple 220 . The locking port 230 is set at the side end of the second temple 220 to facilitate the cooperation between the locking tongue 310 and the locking port 230 .

[0092] In some embodiments, a cavity is formed inside the first temple 210, and the second temple 220 is slidably disposed in the cavity. A second elastic member (not shown), such as a spring, is disposed between the first temple 210 and the second temple 220, and the second elastic member is configured to drive the second temple 220 to extend from the first temple 210.

[0093] A slideway may be provided between the inner peripheral wall of the first temple 210 and the outer peripheral wall of the second temple 220 to improve the reliability of the sliding connection therebetween. A stopper structure such as a protrusion may be provided on the slideway to prevent the second temple 220 from being separated from the first temple 210.

[0094] When the second temple 220 moves toward the inner cavity of the first temple 210 , the second elastic member contracts under the force.

[0095] When the locking portion 300 releases the locking of the temple portion 200 in the folded state, the second temple 220 extends outward from the first temple 210 under the action of the rebound force of the second elastic member.

[0096] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0097] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
