Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and in particular to a smart glasses with bone conduction headphones. Background Technology

[0002] With the development of science and technology, smart glasses with bone conduction headphones and microphones are becoming increasingly popular. This is because users can make or receive calls while driving without using their hands, and bone conduction headphones do not isolate the user's eardrums from the outside world, allowing them to receive external sound information while on the phone or listening to music, thus reducing driving safety hazards. Existing bone conduction headphones typically connect to the temples of smart glasses via a hinge, allowing the headphones to rotate relative to the temples around the connecting axis to fit different face shapes. However, it has been found that when these headphones are powered on, frequent rotation to change their position can cause unexpected power outages, damaging the headphones and causing inconvenience to users. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a smart glasses with bone conduction headphones.

[0004] A smart glasses with bone conduction headphones includes: a frame; lenses symmetrically embedded in the frame; two temples rotatably disposed at the left and right ends of the frame; each temple having an internal mounting space; a connecting assembly including a connecting shaft and a rotating arm; the connecting shaft protruding from the inner surface of one side of the mounting space and extending in a left-right direction; a connecting hole at one end of the rotating arm extending through the rotating arm in a left-right direction; the connecting hole being fitted onto the outside of the connecting shaft, and the rotating arm being foldable into or extended out of the mounting space; bone conduction headphones disposed at the end of the rotating arm away from the temple for transmitting sound to the user; and an electrical connection assembly including a second electronic component disposed in the temple, a third electronic component disposed in the rotating arm, a first electrical connector, and a second electrical connector; the first electrical connector surrounding the outer circumferential surface of the connecting shaft and electrically connected to the second electronic component; the second electrical connector surrounding the inner circumferential surface of the connecting hole and electrically connected to the third electronic component; when the connecting shaft is inserted into the connecting hole, the first electrical connector and the second electrical connector contact each other and are electrically connected.

[0005] The smart glasses with bone conduction headphones described in this invention achieve electrical connection between the second and third electronic components through curved contact of the first and second electrical connectors on annular surfaces, ensuring the stability of the electrical connection. Even if the connecting shaft and rotating arm become loose in the axial direction, it will not affect the electrical connection.

[0006] Furthermore, the connecting assembly also includes a pivot cap, which is sleeved on the end of the connecting shaft near the connecting hole and covers the connecting hole.

[0007] Through the above technical solution, the swivel cap forms a seal between the connecting hole and the connecting shaft, protecting the first electrical connector and the second electrical connector.

[0008] Furthermore, the connecting assembly also includes a connecting block, which is fixedly installed on one inner surface of the mounting space; the connecting shaft protrudes from the other end face of the connecting block; when the connecting shaft is inserted into the connecting hole, the end face of the rotating arm facing the connecting block is connected to the connecting block.

[0009] Through the above technical solution, the end face of the rotating arm facing the connecting block contacts the connecting block, thereby enhancing the structural stability between the rotating arm and the connecting shaft.

[0010] Furthermore, the connecting assembly also includes a first magnetic component and a second magnetic component; the first magnetic component is disposed on the end face of the rotating arm facing the connecting block and surrounds the outside of the connecting hole; the second magnetic component is correspondingly disposed on the end face of the connecting block and surrounds the outside of the connecting shaft; when the connecting shaft is inserted into the connecting hole, the first magnetic component and the second magnetic component are attracted to each other.

[0011] The above technical solution uses magnetic attraction to keep the end face of the rotating arm facing the connecting block in contact with the end face of the connecting block, thus preventing the rotating arm from swaying back and forth along the axis of the connecting shaft.

[0012] Furthermore, a first limiting block and a second limiting block are respectively provided on the rear and upper sides of the connecting block. When the rotating arm is extended, the rotating arm abuts against the first limiting block; when the rotating arm is retracted into the installation space, the rotating arm abuts against the second limiting block.

[0013] The above technical solution limits the rotation angle of the rotating arm by the first and second limiting blocks, preventing the user from applying too much force, causing the rotating arm to rotate excessively and collide with the temple, resulting in damage.

[0014] Furthermore, the temple includes a first housing and a second housing. The first housing has a recessed mounting groove on the side facing the second housing. The second housing is detachably covered onto the first housing, thereby enclosing and forming the mounting space. An opening is provided below the mounting space, and the end of the rotating arm away from the connecting shaft extends out of the mounting space from the opening.

[0015] Furthermore, a receiving groove is also provided on the end face of the second housing facing away from the first housing. The receiving groove is connected to the opening and the installation space. The length of the receiving groove is greater than the distance from the end of the bone conduction earphone away from the temple to the connecting shaft. When the rotating arm is in the folded state, the rotating arm and the bone conduction earphone are accommodated in the receiving groove.

[0016] The above technical solution uses a receiving slot to house and protect the rotating arm and bone conduction headphones.

[0017] Furthermore, a third magnetic component is provided in the receiving slot, and a fourth magnetic component is provided on the bone conduction earphone. When the bone conduction earphone is stored in the receiving slot, the third magnetic component and the fourth magnetic component are attracted to each other.

[0018] Through the above technical solution, the bone conduction headphones can be stably suspended in the storage slot by the adsorption and cooperation of the third and fourth magnetic components.

[0019] Furthermore, the rear end of the temple is provided with a corner portion and a rear extension portion. The corner portion is in the shape of an upwardly convex arc. The rear extension portion is connected to the end of the corner portion away from the frame and extends downward at an angle.

[0020] The above technical solution allows the corner and rear extension to fit behind the user's ear, making it convenient for the user to fix the position of the glasses when wearing them.

[0021] Furthermore, the first electrical connector and the second electrical connector are conductive coatings or plasma flexible conductive films.

[0022] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0030] The applicant researched and analyzed existing smart glasses with bone conduction headphones and found that the frequent rotation of the headphones during power-on use easily damages them. The existing headphones are mounted on a rotating arm with a blind hole. A connecting shaft protrudes from the temple and inserts into the blind hole to rotatably connect the rotating arm and temple. Electrical contacts are placed on the bottom surface of the blind hole and the end face of the connecting shaft, achieving a planar electrical connection when the shaft is inserted. However, to reduce friction between the rotating arm and the temple, ensuring smooth rotation and facilitating installation, the rotating arm typically has an axial tolerance with the temple. This makes the electrical connection structure unstable. Frequent rotation of the rotating arm around the connecting shaft can loosen the fit between the arm and shaft, causing the electrical contacts on the bottom surface of the blind hole and the end face of the connecting shaft to separate. This results in intermittent power supply to the bone conduction headphones, ultimately damaging them.

[0031] Based on this, the applicant provides a smart glasses with bone conduction headphones. The bone conduction headphones are mounted on a rotating arm, one end of which has a connecting hole, which is a through hole. A connecting shaft protrudes from the inner surface of the temple. A first electrical connector and a second electrical connector are respectively provided on the outer circumferential surface of the connecting shaft and the inner surface of the connecting hole. When the connecting shaft is inserted into the connecting hole, the first and second electrical connectors ensure stable electrical connection between the rotating arm and the temple through the curved contact of their annular surfaces. Even if the fit between the rotating arm and the connecting shaft becomes loose in the axial direction, the electrical connection will not be affected, thus protecting the bone conduction headphones. The following is one embodiment of the smart glasses with bone conduction headphones provided by this utility model:

[0032] Specifically, when a user wears the smart glasses with bone conduction headphones, the user's face is facing forward, and the user's back is the rear; the user's left and right sides are the left and right sides respectively; the user's top and bottom sides are the top and bottom respectively; at this time, the frame 1 is located at the front end of the temple 3, the temple 3 extends in the front-back direction, and the symmetrical center line of the frame 1 is located in the middle of the frame 1 and extends in the top-bottom direction.

[0033] Please refer to Figures 1 to 7 , Figure 1 A schematic diagram of the spatial structure of the smart glasses with bone conduction headphones provided by this utility model; Figure 2A schematic diagram of the spatial mechanism of the temple of the mirror provided by this utility model; Figure 3 A schematic diagram of the spatial structure of the rotating arm and connecting block provided by this utility model; Figure 4 for Figure 3 Enlarged view of point A in the middle; Figure 5 for Figure 3 Exploded view of the structure; Figure 6 A schematic diagram of the spatial structure of the second shell provided by this utility model; Figure 7 A schematic diagram of the spatial structure of the rotating arm provided by this utility model.

[0034] This invention provides smart glasses with bone conduction headphones, including a frame 1, lenses 2, temples 3, a connecting component 4, bone conduction headphones 5, and an electrical connection component 6. The frame 1 has two temples 3 and two lenses 2, each embedded in the frame 1 and mirror-imaged along the center line of symmetry of the frame 1. The two temples 3 are rotatably mounted on the left and right ends of the frame 1 about an axis extending vertically, mirror-imaged along the center line of symmetry of the frame 1. By rotating the two temples 3, they can be unfolded or folded relative to the frame 1 about the vertical axis, facilitating storage and use. The bone conduction headphones 5 are rotatably mounted on the temples 3 via the connecting component 4. The electrical connection component 6 runs wires sequentially within the frame 1, temples 3, and connecting component 4, and is electrically connected to the bone conduction headphones 5, forming a closed circuit loop.

[0035] Furthermore, the frame 1 is also provided with two spaced nose pads 11, which are mirror images of each other along the center line of symmetry of the frame 1. When the user wears the smart glasses with bone conduction headphones, the nose pads 11 contact the user's bridge of the nose to form support, which facilitates the fixation of the smart glasses with bone conduction headphones.

[0036] The temple 3 includes a first housing 31 and a second housing 32. The first housing 31 and the second housing 32 are detachably connected. The first housing 31 has a recessed mounting groove 310, and the second housing 32 covers the opening of the mounting groove 310 of the first housing 31, forming a mounting space (not shown in the figure). The mounting space has an opening 321 on its downward-facing side, connecting to the outside, so that the connecting component 4 can enter and exit the mounting space. In this embodiment, projected along the front-back direction, the first housing 31 is located on the inner side, and the second housing 32 is located on the outer side; the opening 321 is located below the second housing 32, and the opening 321 communicates with the mounting space.

[0037] Furthermore, each temple 3 has a corner portion 33 and a rear extension portion 34 at its rear end. The corner portion 33 is an upwardly convex arc shape, and the rear extension portion 34 is connected to the end of the corner portion 33 away from the frame 1 and extends downward at an angle. When the user wears the smart glasses, the corner portion 33 is located above the user's ear, hooking the back of the user's ear, and together they position the temple 3 behind the ear. At the same time, the two temples 3 cooperate with each other to provide a certain clamping force to the head, making the smart glasses more stable and less likely to fall off.

[0038] The connecting assembly 4 includes a connecting block 41 and a rotating arm 42. The connecting block 41 is located within the mounting space and is fixedly mounted on the inner wall of the first housing 31. A connecting shaft 411 protrudes from the center of the connecting block 41, extending towards the second housing 32 in a left-right direction. One end of the rotating arm 42 has a connecting hole 421 that penetrates the rotating arm 42 in a left-right direction. In use, the connecting hole 421 faces the connecting shaft 411 and is fitted onto the outside of the connecting shaft 411. The end of the connecting shaft 411 away from the connecting block 41 passes through the connecting hole 421 and contacts the inner surface of the second housing 32, thereby mounting the rotating arm 42 onto the connecting block 41. Simultaneously, the end of the rotating arm 42 away from the connecting hole 421 passes through the opening 321 and extends out of the temple 3. When the rotating arm 42 is folded, it is clamped between the first housing 31 and the second housing 32 and rotates around the connecting shaft 411.

[0039] Furthermore, the connecting assembly 4 also includes a first magnetic element 43 and a second magnetic element 44. The first magnetic element 43 is disposed on the end face of the rotating arm 42 facing the connecting block 41 and surrounds the outside of the connecting hole 421; the second magnetic element 44 is correspondingly disposed on the end face of the connecting block 41 and surrounds the outside of the connecting shaft 411. When the connecting shaft 411 is inserted into the connecting hole 421, the first magnetic element 43 and the second magnetic element 44 attract each other, so that the end face of the rotating arm 42 facing the connecting block 41 is in contact with the end face of the connecting block 41, preventing the rotating arm 42 from wobbling back and forth in the axial direction of the connecting shaft 411.

[0040] The bone conduction headphones 5 are located at the end of the rotating arm 42 away from the temple 3, and are used to transmit sound to the user. The detailed structure of the bone conduction headphones 5 is prior art and will not be described in detail here.

[0041] Furthermore, a first limiting block 412 and a second limiting block 413 are respectively provided on both sides of the connecting block 41 to limit the rotation angle of the rotating arm 42. The first limiting block 412 protrudes behind the rotating arm 42, and when the rotating arm 42 abuts against the first limiting block 412, it reaches the extreme position of being unfolded; the second limiting block 413 protrudes above the rotating arm 42, and when the rotating arm 42 abuts against the second limiting block 413, it reaches the extreme position of being folded, and cannot continue to rotate outward, so as to avoid the user using too much force to rotate the rotating arm 42 excessively and damage it to the temple 3.

[0042] Furthermore, a receiving groove 322 is provided on the end face of the second housing 32 facing away from the first housing 31. The receiving groove 322 extends along the length of the second housing 32 and communicates with the opening 321 and the mounting space. The length of the receiving groove 322 is slightly greater than the distance from the end of the bone conduction earphone 5 away from the temple 3 to the connecting shaft 411. The lower part of the receiving groove 322 communicates with the outside. When the user does not need to use the bone conduction earphone 5, the rotating arm 42 rotates around the connecting shaft 411 and drives the bone conduction earphone 5 into the receiving groove 322 for safekeeping.

[0043] Furthermore, the end of the receiving groove 322 away from the connecting shaft 411 is provided with a third magnetic element 323, and the end of the bone conduction earphone 5 away from the connecting shaft 411 is provided with a fourth magnetic element (not shown). When the bone conduction earphone 5 is retracted into the receiving groove 322 along with the rotating arm 42, the third magnetic element and the fourth magnetic element are attracted to each other, ensuring that the bone conduction earphone 5 can be stably stored in the receiving groove 322 when the user does not need to use the bone conduction earphone 5.

[0044] The electrical connection assembly 6 includes a first electronic component (not shown) disposed within the frame 1, a second electronic component (not shown) disposed within the temple 3, a third electronic component (not shown) disposed within the rotating arm 42, a first electrical connector 61, and a second electrical connector 62. The first, second, and third electronic components may include circuit boards, microphones, batteries, cables, etc., which implement various functions in the prior art. In this embodiment, the first and third electronic components are cables, thereby reducing the thickness of the frame 1 and the rotating arm 42 and improving the aesthetics of the smart glasses; the second electronic component includes a circuit board, microphone, cable, and battery. The first electrical connector 61 is disposed around the outer peripheral surface of the connecting shaft 411 and is electrically connected to the second electronic component; the second electrical connector 62 is disposed around the inner surface of the connecting hole 421 and is electrically connected to the third electronic component. Preferably, the first electrical connector 61 covers the outer peripheral surface of the connecting shaft 411, and the second electrical connector 62 covers the inner sidewall of the connecting hole 421. The first electrical connector 61 and the second electrical connector 62 can be made of conductive coatings, plasma flexible conductive films, etc., as used in the prior art. When the connecting shaft 411 is inserted into the connecting hole 421, the first electrical connector 61 and the second electrical connector 62 come into contact, so that the second electronic component is electrically connected to the third electronic component. The bone conduction earphone 5 is electrically connected to the third electronic component, thereby forming a closed circuit loop by sequentially connecting the bone conduction earphone 5, the rotating arm 42, the temple 3, and the frame 1. Since the first electrical connector 61 and the second electrical connector 62 are in contact via a curved surface of an annular surface, and the connecting shaft 411 extends between the first housing 31 and the second housing 32, the rotating arm 42 is clamped between the first housing 31 and the second housing 32 and cannot detach from the connecting shaft 411. Therefore, even if the rotating arm 42 becomes axially loose when rotating around the connecting shaft 411, the first electrical connector 61 and the second electrical connector 62 can always maintain contact, thereby ensuring a stable electrical connection between the second electronic component and the third electronic component and preventing damage to the bone conduction headphones 5 caused by intermittent power outages and reconnections.

[0045] Furthermore, the connecting assembly 4 also includes a pivot cap 45, which covers the connecting hole 421 and is sleeved on the end of the connecting shaft 411 away from the connecting block 41, forming a seal between the connecting shaft 411 and the connecting hole 421, thereby isolating the first electrical connector 61 and the second electrical connector 62 from the outside world to form protection.

[0046] This invention provides a smart glasses with bone conduction headphones. The unfolding angle of the bone conduction headphones can be adjusted according to individual needs to fit the user's face shape. At the same time, the second electronic component set in the temple and the third electronic component set in the rotating arm ensure stable electrical connection through the curved contact of the annular surface. This ensures that when the user rotates the bone conduction headphones to adjust their position by rotating the arm, there will be no intermittent power failure or interruption, thereby avoiding damage to the bone conduction headphones and improving the user experience.

[0047] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
