Description

Technical Field

[0001] The present invention relates to the technical field of smart glasses, and in particular to a pair of smart glasses. Background Art

[0002] With the advancement of science and technology, smart glasses designed with bone conduction headphones and microphones are becoming increasingly popular. This is because they allow users to answer or make calls while driving without using their hands. Furthermore, bone conduction headphones transmit sound without isolating the eardrum from the outside world, allowing users to receive external sound information while answering calls or listening to music, reducing driving safety risks.

[0003] Based on this, some smart glasses with integrated bone conduction headphones have appeared in the prior art. For example, Chinese patent application CN201920510612.3 provides a bone conduction pair of glasses, including a glasses frame, glasses lenses and bone conduction glasses feet. The glasses lenses are embedded in the glasses frame; the bone conduction glasses feet include glasses feet and bone conduction speakers, the glasses feet are connected to the glasses frame, and the bone conduction speakers are fixedly connected to the middle position outside the glasses foot shell. The above-mentioned bone conduction glasses fix the bone conduction speakers on the temples of the glasses and transmit sound by transmitting vibrations to the user's facial bones. However, when the user wears the bone conduction glasses, on the one hand, the two bone conduction speakers will press against the user's face and cause discomfort. On the other hand, the position of the facial bones of different user groups is different. The bone conduction glasses cannot adjust the position of the bone conduction speakers according to the needs of different users, which affects the user's experience. Summary of the Invention

[0004] Based on this, an object of the present invention is to provide smart glasses.

[0005] A pair of smart glasses, comprising: a frame; lenses symmetrically embedded in the frame; two temples rotatably arranged at the left and right ends of the frame; an installation space provided inside each temple; a connecting assembly, comprising a connecting shaft and a rotating arm, the connecting shaft protruding from one side surface of the installation space or one of the rotating arms and extending in the left-right direction, a connecting hole being provided on one side surface of the installation space or the other of the rotating arms, the connecting shaft being inserted into the connecting hole, so that the rotating arm can rotate around the connecting shaft and be folded into the installation space, or unfolded and extended out of the installation space; a bone conduction earphone, mounted on the end of the rotating arm away from the temple, for transmitting sound to the user; an electrical connecting assembly, wherein the electrical connecting assembly and the bone conduction earphone are electrically connected to form a closed electronic circuit.

[0006] In the smart glasses described in the present invention, the bone conduction earphone is set on a rotating arm, and the rotating arm is rotatably installed in the installation space of the temple through the cooperation of the connecting axis and the hole axis of the connecting hole. By rotating the rotating arm around the connecting axis, the position of the bone conduction earphone is changed, thereby adapting to the needs of users with different face shapes and improving the user experience.

[0007] Furthermore, the connection assembly further includes a connection block, which is fixedly mounted on one of the side surfaces of the installation space or one of the rotating arms, and the connection axon is provided on the connection block.

[0008] Through the above technical solution, the end surface 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.

[0009] Furthermore, the rotating arm is an elastic part, and the connecting hole is opened on the rotating arm, and the connecting block is fixedly installed on one of the side surfaces of the installation space; projected along the left and right directions, the cross-sectional shape of the connecting hole is a square hole, the cross-sectional shape of the connecting shaft is an ellipse, and the length of the major axis of the connecting shaft is greater than the side length of the connecting hole.

[0010] Through the above technical solution, when the rotating arm rotates around the connecting axis, the outer peripheral surfaces of the connecting axis close to the two ends of the long axis contact the inner surface of the connecting hole in turn and cause it to elastically deform, thereby increasing the friction damping of the rotating arm rotating around the connecting axis, making it easier for users to fix the bone conduction headphones at a certain unfolding angle.

[0011] Furthermore, projected along the left-right direction, both ends of the long axis and both ends of the short axis of the connecting shaft are respectively connected to two opposite sides of the connecting hole.

[0012] Through the above technical solution, the two ends of the long axis of the connecting shaft cause the two opposite sides of the connecting hole to undergo elastic deformation to increase the friction damping, and the two ends of the short axis of the connecting shaft contact the two opposite sides of the connecting hole to provide a certain friction damping, thereby making the damping feel of the rotating arm rotating around the connecting shaft optimal.

[0013] Furthermore, an annular protrusion surrounding the outer circumference of the connecting hole is protruded from the end face of the rotating arm facing the connecting block; an annular groove matching the annular protrusion is provided on the end face of the connecting block facing the rotating arm; when the connecting shaft is inserted into the connecting hole, the annular protrusion is inserted into the annular groove.

[0014] Through the above technical solution, when the connecting shaft is inserted into the connecting hole, the annular protrusion is inserted into the annular groove, so that the connection between the rotating arm and the connecting block is more stable.

[0015] Furthermore, the electrical connection assembly includes a first electronic component arranged in the frame, a second electronic component arranged in the temple, a third electronic component arranged in the rotating arm, a first electrical connector and a second electrical connector; the first electronic component and the second electronic component are electrically connected; the first electrical connector is arranged on the end surface of the annular protrusion facing the annular groove, and is electrically connected to the third electronic component; the second electrical connector is arranged on the bottom surface of the annular groove, and is electrically connected to the second electronic component; when the annular protrusion is inserted into the annular groove, the first electrical connector and the second electrical connector are in contact and electrically connected.

[0016] Through the above technical solution, the first electrical connector and the second electrical connector realize the electrical connection between the second electronic component and the third electronic component through the planar contact of the annular surface, ensuring that the electrical connection between the second electronic unit and the third electronic unit will not be affected by the fit between the irregularly shaped connecting shaft and the connecting hole, thereby ensuring the stability of the electrical connection.

[0017] Furthermore, a first limit block and a second limit block are respectively provided on the rear side and the upper side of the connecting block. When the rotating arm is unfolded, the rotating arm abuts against the first limit block; when the rotating arm is stored in the installation space, the rotating arm abuts against the second limit block.

[0018] With the above technical solution, the first limit block and the second limit block limit the rotation angle of the rotating arm, thereby preventing the user from excessively rotating the rotating arm and colliding with the temple to cause damage due to excessive force.

[0019] Furthermore, the temple includes a first shell and a second shell, the first shell is provided with a mounting groove on a side facing the second shell, the second shell is detachably covered on the first shell to enclose the mounting space, an opening is provided below the mounting space, and the end of the rotating arm away from the connecting axis extends out of the mounting space from the opening.

[0020] Furthermore, a receiving groove is provided on the end surface of the second shell facing away from the first shell, and 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 axis, and is used to accommodate the rotating arm and the bone conduction earphone.

[0021] Through the above technical solution, the rotatable arm and the bone conduction earphones are housed and protected by the accommodating groove.

[0022] Furthermore, a third magnetic component is provided in the accommodating groove, and a fourth magnetic component is provided on the bone conduction earphone. When the bone conduction earphone is received into the accommodating groove along with the rotating arm, the third magnetic component is attracted to the fourth magnetic component.

[0023] Through the above technical solution, the bone conduction earphones can be stably suspended in the storage slot through the adsorption and cooperation of the third magnetic part and the fourth magnetic part.

[0033] To address the drawback of existing smart glasses, where the bone conduction speakers cannot be adjusted, thus failing to meet the needs of users with different face shapes, the applicant provides smart glasses with an installation space provided inside the temples. A connecting shaft extending in the left-right direction is protruded from the installation space. A bone conduction earphone is mounted on one end of a rotating arm. The other end of the rotating arm extends into the installation space and is sleeved on the connecting shaft, allowing it to rotate around the connecting shaft, thereby changing the position of the bone conduction earphone to meet the needs of different user face shapes. The following is one embodiment of the smart glasses provided by the present invention:

[0034] Please refer to Figures 1 to 8 , Figure 1 A schematic diagram of the spatial structure of the smart glasses provided by the present invention; Figure 2 A schematic diagram of the spatial structure of the temples provided by the present invention; Figure 3 A schematic diagram of the spatial structure of the rotating arm and the connecting shaft provided by the present invention; Figure 4 for Figure 3 Enlarged view of point A in the middle; Figure 5 A schematic diagram of the spatial structure of the first shell provided by the present invention; Figure 6 for Figure 5 Enlarged view of point B in the middle; Figure 7 A schematic diagram of the spatial structure of the second shell provided by the present invention; Figure 8 This is a schematic diagram of the spatial structure of the rotating arm provided by the present invention.

[0035] The present invention provides smart glasses, comprising a frame 1, lenses 2, temples 3, a connecting assembly 4, a bone conduction headset 5, and an electrical connecting assembly 6. The temples 3 and lenses 2 are each provided in two numbers, and the two lenses 2 are respectively embedded in the frame 1, and the two lenses 2 are mirrored left and right along the symmetry centerline of the frame 1. The two temples 3 are respectively arranged at the left and right ends of the frame 1 so as to rotate relative to each other around an axis extending in the vertical direction, and are mirrored left and right along the symmetry centerline of the frame 1. By rotating the two temples 3, the two temples 3 can be unfolded or folded relative to the frame 1 for easy storage and use. The bone conduction headset 5 is rotatably mounted on the temples 3 via the connecting assembly 4 and is detachably connected to the temples 3. The electrical connecting assembly 6 is routed in the frame 1, the temples 3, and the connecting assembly 4 in sequence, and is electrically connected to the bone conduction headset 5, forming a closed circuit loop.

[0036] The temple 3 includes a first shell 31 and a second shell 32. The first shell 31 and the second shell 32 are detachably connected. The first shell 31 is recessed with a mounting groove 310, and the second shell 32 is mounted on the opening of the mounting groove 310 of the first shell 31, thereby forming an installation space (not shown). The installation space is provided with an opening 321 connected to the outside on one side facing downward, facilitating the entry and exit of the connecting assembly 4 into and out of the installation space. In this embodiment, projected in the front-to-back direction, the first shell 31 is located on the inner side, and the second shell 32 is located on the outer side; the opening 321 is located below the second shell 32 and communicates with the installation space.

[0037] Furthermore, the rear ends of the temples 3 are each provided with a corner portion 33 and a rear extension portion 34. The corner portion 33 is in the shape of an upwardly protruding arc, and the rear extension portion 34 is connected to the end of the corner portion 33 away from the frame 1 and extends downwardly at an angle. When the user wears the smart glasses, the corner portion 33 is located above the back of the user's ear and hooks onto the back of the user's ear, and the two corner portions 33 together 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 on the head, making the smart glasses more stable when worn 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 positioned within the mounting space and fixedly mounted on the inner wall of the first housing 31. A connecting shaft 411 protrudes from the center of the connecting block 41 and extends horizontally toward the second housing 32. A connecting hole 421 is defined at one end of the rotating arm 42. The connecting hole 421 extends horizontally through the rotating arm 42, with its axis parallel to the horizontal direction. During use, the connecting hole 421 opens toward the connecting shaft 411 and is inserted into the connecting hole 421. The side of the rotating arm 42 defining the connecting hole 421 contacts the side of the connecting block 41, while the side of the rotating arm 42 facing away from the connecting hole 421 contacts the inner surface of the second housing 32, thereby connecting the rotating arm 42 to the connecting block 41. The other end of the rotating arm 42 passes through the opening 321 and extends out of the temple 3. When the rotating arm 42 is folded, the rotating arm 42 is clamped between the first shell 31 and the second shell 32 and rotates around the connecting shaft 411 .

[0039] Furthermore, projected along the left-right direction, the cross-sectional shape of the connecting hole 421 is a square hole or a square hole with rounded corners, and the rotating arm 42 is an elastic member. Specifically, the rotating arm 42 can be made of materials such as rubber or spring steel in the prior art. The cross-sectional shape of the connecting shaft 411 is an ellipse, and the length of the long axis of the connecting shaft 411 is greater than the side length of the connecting hole 421. As the rotating arm 42 rotates around the connecting shaft 411, the outer peripheral surfaces close to the two ends of the long axis of the connecting shaft 411 sequentially abut against the four inner surfaces of the connecting hole 421, causing the connecting hole 421 to deform, thereby increasing the friction between the outer peripheral surface of the connecting shaft 411 and the inner surface of the connecting hole 421, so that the rotating arm 42 produces different damping feels when rotating around the connecting shaft 411, making it convenient for the user to fix the deployment angle of the bone conduction earphone 5. In this embodiment, when projected in the left-right direction, the minor axis of the connecting shaft 411 is less than or equal to the side length of the connecting hole 421; the two ends of the major axis of the connecting shaft 411 and the two ends of the minor axis are respectively connected to the two opposite sides of the connecting hole 421. The two ends of the major axis of the connecting shaft 411 cause the two opposite sides of the connecting hole 421 to elastically deform to increase friction damping, and the two ends of the minor axis of the connecting shaft 411 contact the two opposite sides of the connecting hole 421 to provide a certain amount of friction damping, thereby optimizing the damping feel of the rotating arm rotating about the connecting shaft 411. In other embodiments, the cross-section of the connecting shaft 411 can be other irregular shapes; in other embodiments, the cross-section of the connecting shaft 411 can be square, and the cross-section of the connecting hole 421 can be other irregular shapes including polygonal; in addition, in some embodiments, the connecting shaft 411 can be protruding from the end surface of the rotating arm 42, and the connecting hole 421 can be opened on the connecting block 41. As long as the damping feeling of the rotating arm 42 rotating around the connecting shaft 411 can be improved, the present invention is not limited thereto.

[0040] Furthermore, an annular protrusion 422 is provided on the end surface of the rotating arm 42 facing the connecting block 41. The annular protrusion 422 surrounds the outer circumference of the connecting hole 421 and is coaxial with the connecting hole 421. In this embodiment, when projected in the left-right direction, the inner edge of the annular protrusion 422 forms the circumscribed circle of the connecting hole 421. An annular groove 412 is provided on the end surface of the connecting block 41 facing the rotating arm 42, which mates with the annular protrusion 422. The annular groove 412 is coaxial with the connecting shaft 411 and surrounds the outside of the connecting shaft 411. The connecting shaft 411 is inserted into the connecting hole 421, and the annular protrusion 422 is inserted into the annular groove 412, thereby further stabilizing the connection between the rotating arm 42 and the connecting block 41.

[0041] The bone conduction earphone 5 is arranged at the end of the rotating arm 42 away from the temple 3 and is used to transmit sound to the user. The detailed structure of the bone conduction earphone 5 is prior art and will not be described in detail here. In this embodiment, the bone conduction earphone 5 is integrally connected to the rotating arm 42. When the bone conduction earphone 5 is damaged, the first shell 31 and the second shell 32 are separated, and the bone conduction earphone 5 is disassembled together with the rotating arm 42 for replacement to improve the stability of the connection structure of the bone conduction earphone 5. In other embodiments, the bone conduction earphone 5 and the rotating arm 42 are split structures and are connected by a snap connection or a magnetic connection. When the bone conduction earphone 5 is damaged, the bone conduction earphone 5 is directly disassembled and replaced to facilitate replacement of the bone conduction earphone 5. The present invention is not limited to this.

[0042] Furthermore, a first limit block 413 and a second limit block 414 are respectively provided on both sides of the connecting block 41 for limiting the rotation angle of the rotating arm 42. The first limit block 413 is provided protrudingly behind the rotating arm 42. When the rotating arm 42 abuts against the first limit block 413, it reaches the ultimate extended position. The second limit block 414 is provided protrudingly above the rotating arm 42. When the rotating arm 42 abuts against the second limit block 414, it reaches the ultimate collapsed position and cannot be rotated further outward. This prevents the user from excessively rotating the rotating arm 42 with excessive force and causing it to hit the temple 3 and cause damage.

[0043] Furthermore, a receiving slot 322 is defined on the end surface of the second housing 32 facing away from the first housing 31. This slot 322 extends along the length of the second housing 32 and communicates with the opening 321 and the mounting space. The length of the slot 322 is slightly greater than the distance from the end of the bone conduction earphone 5 distal from the temple 3 to the connecting shaft 411. The lower portion of the slot 322 communicates with the outside. When the user no longer needs to use the bone conduction earphone 5, the rotating arm 42 rotates about the connecting shaft 411, driving the bone conduction earphone 5 into the slot 322 for storage and protection.

[0044] Furthermore, the accommodating groove 322 has a first magnetic member 323 at one end away from the connecting shaft 411, and the bone conduction earphone 5 is provided with a second magnetic member (not shown) at one end away from the connecting shaft 411. When the bone conduction earphone 5 is received into the accommodating groove 322 along with the rotating arm 42, the first magnetic member and the second magnetic member are attracted to each other, ensuring that the bone conduction earphone 5 can be stably received in the accommodating groove 322 when the user does not need to use the bone conduction earphone 5.

[0045] 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, and other components that implement various functions as known in the 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 components include a circuit board, a microphone, a cable, and a battery. The first electrical connector 61 is disposed on the end surface of the annular protrusion 422 facing the annular groove 412 and is electrically connected to the third electronic component. The second electrical connector 62 is correspondingly disposed on the bottom surface of the annular groove 412 and is electrically connected to the second electronic component. When the annular protrusion 422 is inserted into the annular groove 412, the first electrical connector 61 contacts the second electrical connector 62, electrically connecting the second electronic component to the third electronic component. The bone conduction earphone 5 is electrically connected to the third electronic unit, thereby sequentially connecting the bone conduction earphone 5, the rotating arm 42, the temple 3, and the frame 1 to form a closed circuit. In this embodiment, the first electrical connector 61 and the second electrical connector 62 can be made of a conductive coating or a plasma flexible conductive film as known in the art. The surface contact between the first electrical connector 61 and the second electrical connector 62 via the annular surface ensures that when the cross-section of the connecting shaft 411 is designed to be irregular and the rotating arm 42 rotates about the connecting shaft 411, the second electronic component maintains a stable electrical connection with the third electronic component. This also ensures that the rotation of the rotating arm 42 has a certain damping feel and that the electrical connection between the rotating arm 42 and the temple 3 remains stable.

[0046] Compared with the prior art, the smart glasses provided by the present invention have the following advantages:

[0047] (1) The present invention installs the bone conduction earphones on a rotating arm, which is mounted on a connecting shaft protruding from the temples and can rotate around the connecting shaft, thereby adjusting the position of the bone conduction earphones to suit the needs of users with different face shapes.

[0048] (2) The rotating arm of the present invention uses a connecting hole with a square cross-section to cooperate with a connecting shaft with an irregular cross-section. At the same time, the rotating arm is an elastic member, so that the rotating arm undergoes elastic deformation when rotating around the connecting shaft, thereby increasing the friction damping between the connecting shaft and the connecting hole, making it easier for users to fix the position of the bone conduction earphones.

[0049] (3) When the rotating arm of the present invention cooperates with the connecting shaft, its left and right end faces respectively contact the end face of the connecting block and the end face of the second shell, ensuring that the cooperation between the rotating arm and the connecting shaft will not be loose in the axial direction. At the same time, the first electrical connector and the second electrical connector are respectively arranged on the end face of the annular protrusion with a circular cross section and the bottom face of the annular groove, ensuring that the electrical connection between the second electronic unit and the third electronic unit will not be affected by the cooperation between the irregularly shaped connecting shaft and the connecting hole, thereby ensuring the stability of the electrical connection.

[0050] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, and the present invention is intended to encompass such modifications and variations.
