[0029] Unless otherwise specified, in the following description, "plurality" means two or more.

[0030] A pair of Figure 1 The smart glasses 10 shown have two temples 12 pivotally connected to two sides of a frame 11 , and two power supplies 13 are respectively coupled to the ends of the temples 12 .

[0031] The smart glasses 10 are one of many known glasses, such as the invention patent case No. I765435B of Taiwan, China. The frame 11 is inlaid with two lenses (not numbered), each of which can be a myopia lens, a hyperopia lens, a non-power lens, a filter lens or an anti-UV lens. At least one of the temples 12 is hollow, and an electronic circuit 25 is disposed inside it (see Figure 4 A housing 36 of the power supply 13 encloses a battery 37 (see Figure 4 ), the battery 37 can be a disposable battery (Primary Battery) or a rechargeable battery (also known as a secondary battery, Secondary Battery).

[0032] The combination referred to herein generally refers to a fast assembly and disassembly coupling structure, which is provided at two opposite ends of the temple 12 and the power supply 13. Next, the specific structures of multiple embodiments of the coupling structure are described in detail one by one as follows.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, the first embodiment of the coupling structure includes: a first fastener 20, which is arranged at the end of the temple 12, and a positive electrode 23 (i.e., the first positive electrode) and a negative electrode 24 (i.e., the first negative electrode) of the first fastener 20 are respectively electrically connected to the electronic circuit 25 through a conductor 26; a second fastener 30, which is arranged at the end of the housing 36 of the power supply 13, and the other positive electrode 34 (i.e., the second positive electrode) and the negative electrode 35 (i.e., the second negative electrode) of the second fastener 30 are respectively electrically connected to the battery 37. When the positive electrode 23 is connected to the positive electrode 34 and the negative electrode 24 is connected to the negative electrode 35, the battery 37 supplies power to the electronic circuit 25.

[0034] Specifically, the first fastener 20 has a cylinder 21, the root of which is formed at the end of the temple 12, and four plates 22 extend equally from the outside of the cylinder 21 in the radial direction. The positive electrode 23 is a metal column, which is embedded in the top of the cylinder 21, with only the end exposed at the top of the cylinder 21. The negative electrode 24 is a metal ring, which is also embedded in the top of the cylinder 21, with part of the top of the cylinder 21 exposed. The negative electrode 24 surrounds the positive electrode 23, and is separated from each other by a distance to avoid short circuit.

[0035] Next, we can see that a recess 31 of the second fastener 30 is sunken into the end of the outer shell 36 of the power supply 13. Four baffles 32 form the wall of the outer shell 36 surrounding the recess 31, so that the shape of an opening 33 of the recess 31 is roughly the same as the outline formed by the cylinder 21 and the four sheets 22. The positive electrode 34 is also a metal column, which is embedded in the interior of the outer shell 36, one end of which is exposed to the bottom of the recess 31, and the other end is electrically connected to the battery 37. The negative electrode 35 is also a metal ring, which is embedded in the interior of the outer shell 36, one end of which is exposed to the bottom of the recess 31, and the other end is electrically connected to the battery 37. The negative electrode 35 surrounds the periphery of the positive electrode 34, and is separated from each other to prevent the occurrence of short circuits.

[0036] When combined, the cylinder 21 enters the recess 31, and each of the plates 22 enters the opening 33 and is lower than the baffle 32. In the process of "entering the inner side of the baffle 32 in the clockwise direction and exiting the inner side of the baffle 32 in the counterclockwise direction (see Figure 3 )”, the cylinder 21 together with each of the sheets 22 rotates at most 1 / 4 of a circle, so that the sheets 22 are aligned with the inner side of the baffle 32, so that the baffle 32 prevents the cylinder 21 from leaving the recess 31 along an axial direction (not shown). According to the electrical connection relationship of “positive electrode 23 connected to positive electrode 34, negative electrode 24 connected to negative electrode 35”, the battery 37 supplies power to the electronic circuit 25.

[0037] exist Figure 5 The structure of the second embodiment of the coupling structure of the utility model is substantially the same as that of the first embodiment, except that: first, the number of the sheet bodies 22 is reduced to two, which extend equally on both sides of the outside of the cylinder 21. The number of the blocking sheets 32 is reduced to two, which are equally formed on both sides of the wall of the recess 31, thereby changing the shape of the opening 33.

[0038] Next, the cylinder 21 enters the recess 31 and rotates at most 1 / 2 turn, driving each of the sheets 22 to move side by side with the inner side of the corresponding baffle 32. In this way, the baffle 32 blocks the sheet 22 and prevents the cylinder 21 from leaving the recess 31, so that the battery 37 supplies power to the electronic circuit 25.

[0039] like Figure 6 , Figure 7 As shown, the structure of the third embodiment of the coupling structure of the utility model is substantially the same as that of the second embodiment, and the difference is that:

[0040] First, the first fastener 20 and the second fastener 30 are interchanged. That is, the first fastener 20 is moved to the end of the power supply 13, and the second fastener 30 is implemented at the end of the temple 12.

[0041] Secondly, the first fastener 20 has a cover 40 and a conductive rod 41. The cover 40 is combined with an open end (not numbered) of the housing 36 to seal the battery 37 inside the power supply 13. The conductive rod 41 passes through the center of the cover 40. The front end of the conductive rod 41 is the positive electrode 23, and the rear end is electrically connected to the positive electrode of the battery 37. The outer surface of the middle section of the conductive rod 41 is the negative electrode 24, which is electrically connected to the negative electrode of the battery 37. In addition, the cylinder 21 stands on the top surface of the cover 40, which can cover a part of the conductive rod 41.

[0042] Furthermore, the positive electrode 34 and the negative electrode 35 of the second fastener 30 are both arranged at the bottom of an assembly chamber 45 of the temple 12 and are electrically connected to the electronic circuit 25 of the temple 12. The second fastener 30 has an additional waterproof ring 42, a positioning ring 43 and a main body 44. The main body 44 secures the end of the temple 12, and the recess 31 is formed inside the main body 44 and communicates with the assembly chamber 45 of the temple 12. Of course, two blocking pieces 32 are formed on both sides of the opening 33 of the recess 31, allowing the waterproof ring 42 to be placed in the main body 44 and adhered to the bottom surface of the recess 31.

[0043] When the conductive rod 41 enters the assembly chamber 45, the waterproof ring 42 blocks the gap between the conductive rod 41 and the cylinder 21 and the main body 44, thereby preventing leakage. The two positive electrodes 23 and 34 are connected, and the two negative electrodes 24 and 35 are connected, so the battery 37 supplies power to the electronic circuit 25. At the same time, the cylinder 21 enters the recess 31, and each of the plates 22 rotates at most 1 / 2 turn and is aligned with the inner side of the baffle 32, so the baffle 32 prevents the cylinder 21 from leaving the recess 31.

[0044] In addition, the positioning ring 43 is arranged inside the assembly chamber 45, and can just clamp a thin neck portion (not numbered) of the conductive rod 41, and cooperate with the blocking effect of the sheet body 22 and the blocking sheet 32 ​​to produce an auxiliary effect on the coupling structure.

[0045] like Figure 8 , Fig. 9 As shown, the structure of the fourth embodiment of the coupling structure of the utility model is substantially the same as that of the third embodiment, and the difference is that:

[0046] In the first fastener 20, there are no cylinder and sheet, but two rods 50. The two rods 50 stand on the top surface of the cover 40, just on both sides of the conductive rod 41. A ball head 51 is formed at the free end of each rod 50, and the diameter of the ball head 51 is larger than the diameter of the rod 50.

[0047] As for the second fastener 30, there is no main body, recess and stopper, but an outer cover 60 is added. The outer cover 60 secures the end of the temple 12 through a bottom plate 66. The waterproof ring 42 is between the bottom plate 66 and the outer cover 60. A central hole 61 of the outer cover 60 is communicated with the assembly chamber 45 of the temple 12 through the waterproof ring 42. Two arc holes 63 are formed in the outer cover 60 and are located on both sides of the central hole 61. One end of each arc hole 63 is a large diameter portion 64, and the other end is a small diameter portion 65.

[0048] The conductive rod 41 enters the central hole 61, passes through the waterproof ring 42, and thus penetrates into the assembly chamber 45. The two positive electrodes 23 and 34 touch each other, and the two negative electrodes 24 and 35 touch each other, so that the battery 37 supplies power to the electronic circuit 25. The arc hole 63 guides the rod 50 to rotate up to 1 / 4 of a turn, so that the ball head 51 moves from the large diameter portion 64 to the small diameter portion 65, so that the outer cover 60 blocks the ball head 51, preventing the power supply 13 from leaving the temple 12.

[0049] After the combination, the waterproof ring 42 blocks the gap between the outer cover 60, the conductive rod 41 and the bottom plate 66 to prevent leakage. In addition, the wall of the outer cover 60 surrounding the central hole 61 is a conical surface 62, which guides the conductive rod 41 to smoothly enter the second fastener 30.

[0050] Thus, the coupling structure helps the power supply 13 to quickly connect with the temple 12, thereby improving the performance of the smart glasses 10 (see Figure 1 ) of battery life. The insufficient power supply 13 is removed and the fully powered power supply 13 is installed to supply the power required by the smart glasses 10 in real time, so that the burden can be reduced without carrying a charger.

[0051] Without departing from the broad concept of the utility model, a person skilled in the art can understand and make changes to the above embodiments. Therefore, the utility model is not limited to the specific embodiments disclosed in the specification, and all modifications made according to the spirit and technical scope of the utility model should be covered and protected by the text content defined in the claims.
