Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a coaxial cable and smart glasses. Background Technology

[0002] Coaxial cables are used for signal transmission and can be applied to smart glasses, such as AR and VR glasses. Currently, existing coaxial cables typically have a uniformly circular cross-section along their length. Smart glasses usually define cable passageways by spacing between components. Since the components vary in shape, the cross-section of these passageways is often different at different locations. To ensure the coaxial cable can pass through all positions within the passageway, the minimum spacing at each point needs to be greater than the outer diameter of the coaxial cable. This results in a cross-sectional area at most points along the passageway being much larger than that of the coaxial cable, leading to a larger overall size of the smart glasses and hindering miniaturization. Summary of the Invention

[0003] The main objective of this invention is to provide a coaxial cable that enables the miniaturization of smart glasses.

[0004] To achieve the above objectives, the coaxial cable proposed in this invention has two ends and a coaxial cable body connecting the two ends. The coaxial cable body includes a first main body segment and a second main body segment, wherein the cross-section of the first main body segment has a different shape and / or area than the cross-section of the second main body segment.

[0005] Optionally, the coaxial cable includes multiple parallel-extending single wires, the first main body segment is provided with a first covering structure covering the multiple single wires, the second main body segment is provided with a second covering structure covering the multiple single wires, and the cross-section of the first covering structure and the cross-section of the second covering structure are different in shape and / or area.

[0006] Optionally, the first coating structure includes two inner coating films covering multiple of the single-element yarns, and a first outer coating film covering the two inner coating films, wherein one inner coating film covers a portion of the single-element yarns, and the other inner coating film covers the remaining single-element yarns.

[0007] Optionally, the first outer covering film is arranged in a racetrack shape.

[0008] Optionally, the second covering structure includes a partition plate and a second outer covering film, with multiple individual wires disposed on both sides of the partition plate, and the second outer covering film covering the partition plate and the multiple individual wires.

[0009] Alternatively, the separator is configured as an adhesive substrate.

[0010] Optionally, the second covering structure has two opposing wire passages for the individual wires to pass through, and the two wire passages are oriented at an angle.

[0011] Optionally, the coaxial cable body further includes a third body segment, wherein the individual wires of the third body segment are exposed to the outside.

[0012] Optionally, a third main body segment is provided between adjacent first main body segments and second main body segments.

[0013] Optionally, the second main body segment has multiple segments, and the third main body segment is provided between any two adjacent second main body segments.

[0014] The present invention also proposes a smart glasses, which includes:

[0015] The main body of the glasses;

[0016] A first mainboard is located on the main body of the glasses;

[0017] Second motherboard; and

[0018] The aforementioned coaxial cable has two ends, one end of which is connected to the first motherboard and the other end of which is connected to the second motherboard.

[0019] Optionally, the main body of the glasses includes a frame and temples connected to the frame, the first main board is disposed on the frame, and the second main board is disposed on the temples.

[0020] In the technical solution of this invention, the coaxial cable has two ends and a coaxial cable body connecting the two ends. The coaxial cable body includes a first main body segment and a second main body segment. The cross-sectional shape and / or area of ​​the first main body segment are different from those of the second main body segment. Obviously, the glasses body has a cable passage for the coaxial cable body to pass through. The coaxial cable body can be adapted to different positions through the cable passage by setting different cross-sectional shapes and / or areas of the first and second main body segments. For example, where the cross-sectional area of ​​the cable passage is small, the smart glasses do not need to increase their volume to increase the cross-sectional area at that location. Where the inner wall surface of the cable passage is irregular, the first or second main body segment can also be set with a corresponding shape to avoid interference, and the smart glasses do not need to increase their volume to increase the cross-sectional area at that location. Thus, miniaturization is possible for smart glasses using the coaxial cable of this solution. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] Coaxial cables are used for signal transmission and can be applied to smart glasses, such as AR and VR glasses. Currently, existing coaxial cables typically have a uniformly circular cross-section along their length. Within smart glasses, the cable routing channels are usually defined by the spacing between components. Since the components have varying shapes, the cross-sections of these channels are often different at different locations. To ensure the coaxial cable can fit through these channels, the minimum spacing at each point must be greater than the outer diameter of the coaxial cable. This results in a cross-sectional area at most points along the channel being much larger than that of the coaxial cable, leading to a larger overall size for the smart glasses and hindering miniaturization. Therefore, this invention proposes a coaxial cable and smart glasses incorporating it, aiming to reduce the difficulty of installing coaxial cables within smart glasses.

[0035] Reference Figures 1 to 5The smart glasses 200 of the present invention can be AR glasses or VR glasses, etc. In one embodiment of the present invention, the smart glasses 200 includes a glasses body 210, a first motherboard 213, a second motherboard 214, and a coaxial cable 100. The second motherboard 214 can be the motherboard of a processing module, which can process a first image captured by a camera into a second image. The first motherboard 213 can be the motherboard of a display module, which can superimpose the second image and output it to the human eye. The coaxial cable 100 connects the first motherboard 213 and the second motherboard 214, and the first motherboard 213 and the second motherboard 214 achieve information transmission through the coaxial cable 100.

[0036] Optionally, in one embodiment, the coaxial cable 100 has two ends 110 and a coaxial cable body 120 connecting the two ends 110. One end 110 is used to connect to a first main board 213, and the other end 110 is used to connect to a second main board 214. The coaxial cable body 120 includes a first body segment 121 and a second body segment 122. The cross-section of the first body segment 121 has a different shape and / or area than the cross-section of the second body segment 122. Obviously, the eyeglass body 210 has a cable passage for the coaxial cable body 120 to pass through. The coaxial cable body 120 can be adapted to different positions through the cable passage by setting different shapes and / or areas of the cross-sections of the first body segment 121 and the second body segment 122. For example, where the cross-sectional area of ​​the cable passage is small, the smart glasses 200 does not need to increase its volume to increase the cross-sectional area at that location. Where the inner wall surface of the cable passage is irregular, the first body segment 121 or the second body segment 122 can also be set with corresponding shapes to avoid interference, and the smart glasses 200 does not need to increase its volume to increase the cross-sectional area at that location. In this way, miniaturization is possible for smart glasses 200 using the coaxial cable 100 of this solution.

[0037] Optionally, in one embodiment, the coaxial cable 100 includes multiple parallel-extending single wires 130, i.e., the coaxial cable 100 is in the form of a wire bundle. A first main body segment 121 is provided with a first covering structure 140 covering the multiple single wires 130. The first covering structure 140 constrains the multiple single wires 130, and under the constraint of the first covering structure 140, the first main body segment 121 can be covered into a shape and / or area with a specific cross-section. A second main body segment 122 is provided with a second covering structure 150 covering the multiple single wires 130. The second covering structure 150 constrains the multiple single wires 130, and under the constraint of the second covering structure 150, the second main body segment 122 can be covered into a shape and / or area with a specific cross-section. Specifically, the different shapes of the cross-sections of the first covering structure 140 and the second covering structure 150 allow for different arrangements of the multiple individual wires 130 they cover. The different cross-sectional areas allow for different outer diameters of the first main body segment 121 and the second main body segment 122, resulting in different shapes and / or areas of the cross-sections of the first main body segment 121 and the second main body segment 122. Alternatively, in other embodiments, the individual wires 130 of the first main body segment 121 and the second main body segment 122 can be connected by adhesive bonding. This method also allows for different arrangements and spacing of the multiple individual wires 130, resulting in different shapes and / or areas of the cross-sections of the first main body segment 121 and the second main body segment 122.

[0038] Optionally, in one embodiment, the first covering structure 140 includes two inner covering films 141 covering multiple individual wires 130, and a first outer covering film 142 covering the two inner covering films 141. One inner covering film 141 covers a portion of the individual wires 130, and the other inner covering film 141 covers the remaining individual wires 130. It is understood that the inner covering film 141 constrains the multiple individual wires 130, while the first outer covering film 142 constrains the two inner covering films 141. Under the constraint of the first outer covering film 142, the two inner covering films 141 can be arranged side-by-side or spirally wound around each other. Furthermore, both the inner covering film 141 and the first outer covering film 142 have a relatively small film thickness, which is beneficial for the miniaturization of the smart glasses 200. Specifically, in one embodiment, the film thickness of the inner covering film 141 ranges from 0.01 mm to 0.05 mm. The thickness of the first outer coating 142 ranges from 0.01 mm to 0.05 mm. Further, in one embodiment, both the inner coating 141 and the first outer coating 142 are configured as insulating films, which can reduce the possibility of short circuits in the smart glasses 200 caused by leakage after the sheath of the individual wire 130 is damaged. It is worth mentioning that in one embodiment, the diameter of the individual wire 130 ranges from 0.01 mm to 0.05 mm; the thinner individual wire 130 is beneficial for the miniaturization of the smart glasses 200.

[0039] Optionally, in one embodiment, the first outer covering film 142 is arranged in a racetrack shape. Specifically, two inner covering films 141 are arranged side by side, and when the first outer covering film 142 covers the two inner covering films 141, it can form two opposing side planes. In this way, the first outer covering film 142 is suitable for fitting with a plane, which facilitates the installation of the coaxial cable 100. For example, the eyeglass body 210 includes a frame 211, a lens disposed on the frame 211, and a temple 212 connected to the frame 211. The wire passage includes a wire groove disposed on the frame 211, which is used to connect the temple 212 and the frame 211. The bottom of the wire groove is flat, so that the side plane of the first outer covering film 142 can fit with the bottom of the wire groove. However, this design is not limited to this. In other embodiments, the first outer covering film 142 is cylindrical. Specifically, the two inner covering films 141 are spirally wound around each other, and the first outer covering film 142 is cylindrical when it covers the two inner covering films 141.

[0040] Optionally, in one embodiment, the second covering structure 150 includes a partition plate 151 and a second outer covering film 152. Multiple individual wires 130 are disposed on both sides of the partition plate 151, and the second outer covering film 152 covers the partition plate 151 and the multiple individual wires 130. Specifically, the partition plate 151 divides the multiple individual wires 130 into two parallel parts. One part includes multiple individual wires 130 arranged side-by-side, and these multiple individual wires 130 are attached to one side of the partition plate 151. The other part also includes multiple individual wires 130 arranged side-by-side, and these multiple individual wires 130 are attached to the other side of the partition plate 151. Thus, the second main body segment 122 is not too thick, making it easy to bend and adapt to curved surfaces. For example, the temple 212 of the smart glasses 200 contains an optical engine 220, and the outer shell of the optical engine 220 has a curved surface. Thus, the second main body segment 122 can be bent to adapt to this curved surface. Furthermore, the second outer coating 152 has a relatively small thickness, which is beneficial for the miniaturization of the smart glasses 200. Specifically, in one embodiment, the thickness of the second outer coating 152 ranges from 0.01mm to 0.05mm. Further, in one embodiment, the second outer coating 152 is configured as an insulating film, which can reduce the possibility of short circuits in the smart glasses 200 caused by leakage current after damage to the sheath of the individual wire unit 130.

[0041] Optionally, in one embodiment, the separator 151 is configured as an adhesive substrate. It is understood that the adhesive substrate is adhesive. This facilitates the adhesion of multiple wire units 130 to the adhesive substrate, which helps improve the efficiency of processing the coaxial cable 100.

[0042] Optionally, in one embodiment, the second covering structure 150 has two opposing wire passages 153 through which the individual wires 130 pass, and the two wire passages 153 are oriented at an angle. It should be noted that an angle is greater than 0° and less than 180°. This changes the orientation of the individual wires 130, allowing the second covering structure 150 to be positioned at corners where corners are needed. For example, the frame 211 includes a frame 211 body and a connecting portion connected to the lens housing body. The connecting portion is hinged to the temple 212. The second covering structure 150 can be located at the connection between the frame 211 body and the connecting portion. This avoids actively bending the coaxial cable 100, thus reducing the stress on the coaxial cable 100 and preventing damage to the individual wires 130 after bending, ensuring a stronger signal transmission from the coaxial cable 100. Specifically, in one embodiment, the second covering film has wire passages 153.

[0043] Optionally, in one embodiment, the coaxial cable body 120 further includes a third body segment 123, with individual wires 130 of the third body segment 123 exposed. Thus, the third body segment 123 has a smaller cross-section, which is advantageous for passing through the smaller inner diameter of the wire passage. Furthermore, since the individual wires 130 of the third body segment 123 are exposed, the multiple individual wires 130 have a higher degree of freedom and are easier to bend, increasing the overall bendability of the coaxial cable 100. It is worth mentioning that in one embodiment, the eyeglass body 210 includes a frame 211 and temples 212 hinged to the frame 211. A first wire passage 231 is provided at the hinge, through which a third body segment 123 passes. The third body segment 123 has high resistance to bending fatigue, preventing the coaxial cable 100 from breaking under repeated bending. Specifically, in one embodiment, the frame 211 and temple 212 are connected by a hinge 230, which is provided with the first wire passage 231. In addition, the smart glasses 200 also includes a dust cover 240 disposed on the hinge 230 for a third main body segment 123 to pass through.

[0044] Optionally, in one embodiment, a third main body segment 123 is provided between adjacent first main body segments 121 and second main body segments 122. In another embodiment, the second main body segment 122 has multiple segments, and a third main body segment 123 is provided between any two adjacent second main body segments 122. It is understood that with the connection of the third main body segment 123, both the first main body segments 121 and the second main body segments 122 are easy to bend.

[0045] Optionally, in one embodiment, the coaxial cable 100 further includes two connectors 170, with one end 110 correspondingly connected to one connector 170. One end 110 is connected to the first motherboard 213 via one connector 170, and the other end 110 is connected to the second motherboard 214 via the other connector 170. It is worth mentioning that, in one embodiment, the individual wires 130 of the end 110 are exposed and arranged side by side with the corresponding connectors 170.

[0046] Optionally, in one embodiment, the glasses body 210 includes a frame 211 and temples 212 connected to the frame 211. A first mainboard 213 is disposed on the frame 211, and a second mainboard 214 is disposed on the temples 212. Thus, the smart glasses 200 has a high degree of integration. Of course, in other embodiments, since the processing module handles complex functions and is relatively large, the second mainboard 214 can be externally mounted to the glasses body 210, for example, externally mounted to a mobile phone.

[0047] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
