Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of head-mounted display, in particular to a hinge device and smart glasses. BACKGROUND

[0002] With the development of science and technology, smart glasses gradually enter people's daily life. The smart glasses usually include a frame and a lens, the frame includes a frame and a temple, wherein the lens is installed in the frame, and one end of the temple is rotatably connected to one end of the frame through a hinge device. The temple and the frame of the smart glasses can be provided with electronic devices such as a loudspeaker, a light machine, a battery, a processing device, etc. to deliver audio, virtual pictures and other information to the wearer and interact with the wearer.

[0003] Because the frame and the temple are provided with electronic devices, the frame and the temple are rigid, and when the wearer wears the smart glasses, the elastic clamping force cannot be provided by deforming the temple like traditional glasses. At the same time, the signal transmission line is needed to transmit electrical signals between the temple and the frame. Therefore, for the hinge device, in addition to providing the folding function of the temple like traditional glasses, it also needs to provide elastic clamping force and a wire passing structure for the signal transmission line to pass through.

[0004] In order to meet the above functional requirements at the same time, the hinge device usually includes a spring, a mounting seat, a bracket and a cover plate. The bracket and the cover plate are fixedly connected, and the two are in a split structure to form an accommodation space for the signal transmission line to pass through. One end of the bracket is rotatably connected to the temple through a connecting shaft, so that the temple can be switched between an unfolded state and a folded state. The spring is installed on the frame through the mounting seat, the bracket is rotatably connected to the mounting seat through a rotating shaft (here, it can be understood as the fulcrum of the lever structure), and the other end of the bracket abuts against the spring. Thus, when the temple is in the unfolded state and the smart glasses are worn, the spring provides an elastic force to the other end of the bracket towards the outside, and through the lever action of the bracket, the one end of the bracket provides an elastic clamping force to the temple towards the inside, thereby clamping the wearer's head.

[0005] As can be seen from the above, in order to provide elastic clamping force, a spring, a mounting seat (i.e. a mounting structure corresponding to the spring), a bracket and a rotating shaft need to be provided at the same time, and the bracket and the cover plate need to be provided at the same time to form a wire passing structure for the signal transmission line to pass through. Therefore, the hinge device has more parts, the assembly relationship is complex, and the structure is complex, which also leads to an increase in weight and space occupation, thereby making the structure of the smart glasses more complex, the assembly process more complex, the production cost higher, and the weight and volume larger, and the experience of the wearer is poorer after wearing for a long time.

[0006] Therefore, the structure of the smart glasses in the prior art is relatively complex, the assembly is difficult, the production cost is high, and it is not conducive to the realization of the lightweight design of the smart glasses. Utility Model Content

[0007] The hinge device and the smart glasses provided by the embodiments of the present application solve the problem that the structure of the smart glasses in the prior art is relatively complex, the assembly is difficult, the production cost is high, and the smart glasses are not conducive to thin design.

[0008] The first aspect of the embodiments of the present application provides a smart glasses, comprising a frame, the frame comprising a frame and a temple. One end of the temple is rotatably connected to one end of the frame by a hinge device, so that the temple can be switched between an unfolded state and a folded state. A signal transmission line is arranged in the frame, and the signal transmission line extends from the frame to the temple through the hinge device.

[0009] The hinge device comprises a spring sheet and a wire shielding member. The first end of the spring sheet in the length direction is fixed to one end of the frame, and the second end of the spring sheet in the length direction is rotatably connected to one end of the temple, so that one end of the temple is rotatably connected to one end of the frame through the spring sheet. The wire shielding member is installed on the spring sheet, and the transmission line segment of the signal transmission line passing through the hinge device is wrapped in the wire shielding member, or wrapped in the structural member formed by the spring sheet and the wire shielding member. When the temple is in the unfolded state and the smart glasses are worn, the temple and the hinge device abut each other, and the elastic clamping force of the temple in the direction of the wearer's head is provided by the elastic deformation of the spring sheet.

[0010] In the smart glasses provided by the embodiments of the present application, the hinge device is provided with a spring sheet, the first end of the spring sheet is fixed to the frame, and the second end is rotatably connected to the temple, so that the temple can be switched between the unfolded state and the folded state. When the temple is in the unfolded state and the smart glasses are worn, the temple is further expanded outward relative to the frame, the hinge device is abutted by the temple, the spring sheet of the hinge device is deformed under the driving of the temple, and an elastic clamping force of the temple in the direction of the wearer's head (or an elastic clamping force of the temple in the direction of the inner side) is provided, so as to provide the clamping force of the whole smart glasses when worn, clamp the head of the wearer, and ensure the stability and reliability of the smart glasses when worn, thereby increasing the compatibility and comfort of the wearer when worn. Wherein, the further expansion of the temple relative to the frame outward can be understood as that, in the length direction of the frame, the temple moves a certain distance relative to the frame in the direction away from the wearer's head, and it can also be understood that, in the case of having two temples, the two temples move a certain distance in the direction away from each other.

[0011] Further, the signal transmission line is used to transmit electrical signals (for example, power signals and / or communication signals) between the temple and the frame, and the transmission line segment of the signal transmission line passing through the hinge device is wrapped by the shielding member or the shielding member and the elastic sheet, so that the signal transmission line can be protected from external damage, the reliability of the electrical signal transmission is ensured, and the signal transmission line can be hidden, so that the appearance of the smart glasses is continuous and beautiful.

[0012] As can be seen from the above, the hinge device of the embodiment of the present application can realize the folding function of the temple by the elastic sheet, and provide an elastic clamping force to the temple to clamp the head of the wearer. Compared with the prior art scheme in which a spring, a mounting seat (i.e., a mounting structure corresponding to the spring), a support, and a rotating shaft are simultaneously provided to realize the above functions, the embodiment of the present application does not need to additionally provide the mounting seat, the support, and the rotating shaft as the support fulcrum, greatly reduces the number of parts, simplifies the part assembly relationship, has a simpler structure, and greatly reduces the assembly difficulty. In addition, due to the great reduction in the number of parts of the hinge device, the weight and the occupied volume of the hinge device can also be greatly reduced, and thus the thickness and the volume of the hinge device of the smart glasses and the thickness and the volume of the connection between the temple and the frame and the hinge device can also be greatly reduced, thereby helping the smart glasses to realize the lightweight design.

[0013] Therefore, the smart glasses provided by the embodiment of the present application have a simple structure, a smaller assembly difficulty, and a lower production cost, and are conducive to realizing the lightweight design of the smart glasses.

[0014] In a possible implementation, the elastic sheet includes an elastic arm, a first mounting arm, and a second mounting arm. The elastic arm has a first end and a second end along the length direction thereof. The first mounting arm is connected to the first end of the elastic arm, the first mounting arm constitutes a first end portion of the elastic sheet, and is fixedly connected to one end portion of the frame. The second mounting arm is connected to the second end of the elastic arm, the second mounting arm constitutes a second end portion of the elastic sheet, and is rotatably connected to one end portion of the temple. The elastic arm is arched toward the outside thereof, and the outside of the elastic arm is the side of the elastic arm away from the head of the wearer when the smart glasses are worn. The elastic sheet is fixed to the frame through the first mounting arm, is rotatably connected to the temple through the second mounting arm, and provides the elastic clamping force to the temple in the direction of the head of the wearer through the elastic arm. The structure is simple, and the elastic sheet with the structure can be made relatively thin under the condition of ensuring the connection strength and the elastic clamping force, so that the thickness of the hinge device can be made thinner, the volume can be made smaller, and the lightweight design of the smart glasses can be better realized.

[0015] In a possible implementation, the elastic arm adopts a strip-shaped structure, and a main body part is provided on the elastic arm except for the first end and the second end of the elastic arm. The main body part is arc-shaped along the length direction of the main body part, and the arc-shaped part is arched towards the outside of the elastic arm. In this way, a more stable elastic clamping force can be provided for the head of the wearer.

[0016] In a possible implementation, the end part of the frame is provided with a mounting table, and the first mounting arm is fixedly connected to the mounting table. In this way, the elastic piece can be conveniently and stably and reliably mounted and fixed to the frame.

[0017] In a possible implementation, a plurality of first fixing holes are arranged at intervals on the mounting table, and a plurality of second fixing holes corresponding to the plurality of first fixing holes are arranged on the first mounting arm. A corresponding fastener is arranged in each first fixing hole and corresponding second fixing hole to fixedly connect the first mounting arm and the mounting table. The first mounting arm of the elastic piece is fixed to the mounting table of the frame by the fastener. The structure is simple, the space occupied is small, the space of the end part of the frame can be fully utilized to fix the elastic piece, the smart glasses can be further designed to be light and thin, the fixing is reliable, and the cost is low.

[0018] In a possible implementation, a first positioning column and a second positioning column are arranged at intervals on the mounting table, and a first positioning hole and a second positioning hole are arranged on the first mounting arm. The first positioning column is arranged in the first positioning hole, and the outer wall surface of the first positioning column matches the inner wall surface of the first positioning hole. The second positioning column is arranged in the second positioning hole, and the second positioning hole is an elongated hole. When the elastic piece is mounted on the frame, the first positioning column can be inserted into the first positioning hole to perform coarse positioning first. Then, the second positioning column is inserted into the second positioning hole, the relative position of the second positioning column relative to the second positioning hole in the length direction of the second positioning hole is adjusted, the fixed position of the first mounting arm and the mounting table is aligned to perform fine positioning, and then the first mounting arm and the mounting table are fixed. For example, the first fixing holes on the mounting table and the corresponding second fixing holes on the first mounting arm are aligned, and then the fastener is inserted thereinto to complete the fixing of the first mounting arm and the mounting table. In this way, the elastic piece can be conveniently, quickly and accurately fixed to the corresponding position of the frame.

[0019] In one possible implementation, the second mounting arm includes a connecting arm and a first fixing arm. The connecting arm is connected to the second end of the elastic arm. The first fixing arm is connected to one side of the connecting arm along the width direction of the spring, so that the connected first fixing arm and the connecting arm form an L-shaped structure. The first fixing arm is rotatably connected to the temple via a first connecting shaft, so that the second mounting arm is rotatably connected to one end of the temple. This allows for very stable and reliable rotation between the spring and the temple, thus enabling better temple folding functionality. Furthermore, when the temple is in the unfolded state, the first connecting shaft can also reliably transmit force between the temple and the spring. For example, when the temple is opened outward (i.e., expanded), the first connecting shaft can also force the spring to undergo elastic deformation, generating an elastic force inward. This elastic force can be transmitted to the temple via the first connecting shaft, thereby providing the wearer's head with an elastic clamping force, ensuring reliable and comfortable wearing. At the same time, the simple structure and small space occupation allow the temples and hinges to be made thinner, which is more conducive to the lightweight design of smart glasses and improves the user experience.

[0020] In one possible implementation, the second mounting arm further includes a second fixing arm, which is connected to the other side of the connecting arm along the width direction of the spring, so that the sequentially connected first fixing arm, connecting arm, and second fixing arm form a U-shaped structure. The first fixing arm and the second fixing arm are positioned opposite each other in the width direction of the temple, and the opening of the U-shaped structure is positioned opposite to the connecting arm in the thickness direction of the temple. The second fixing arm is rotatably connected to the temple via a second connecting shaft, so that the second mounting arm is rotatably connected to one end of the temple. This allows for a more stable and reliable rotation between the spring and the temple, thereby better realizing the folding function of the temple.

[0021] In one possible implementation, a first connecting shaft is fixedly connected to the temple and rotatably connected to a first fixed arm; a second connecting shaft is fixedly connected to the temple and rotatably connected to a second fixed arm. This facilitates the installation of the spring clip onto the temple. The axis of the first connecting shaft and the axis of the second connecting shaft are on the same straight line, and this straight line is parallel to the width direction of the temple.

[0022] In one possible implementation, one end of the frame has a mounting cavity and a through hole. One end of the through hole communicates with the mounting cavity, and the other end extends to the outer surface of one end of the frame. The first end of the spring is fixedly installed in the mounting cavity of the frame, and the spring extends from the mounting cavity through the through hole to the outside of the frame. The part where the spring connects to the frame is hidden inside the frame, which provides better protection and a more aesthetically pleasing appearance.

[0023] In one possible implementation, along the length of the frame, the through hole is located on the side of the mounting cavity facing outwards from the frame, and the other end of the through hole extends to the outer end face of one end of the frame.

[0024] In one possible implementation, the spring includes a first portion, a second portion, and a third portion connected sequentially along its length. The first portion includes a first end of the spring and extends from the mounting cavity through a through-hole to the outside of the frame. The second portion is located between the frame and the temple. The third portion includes a second end of the spring and extends from the inside of the temple through one end face of the temple to the outside of the temple. The hinge device also includes a reinforcing plate, which is stacked on the first portion of the spring and fixedly connected to the first end of the spring, the reinforcing plate, and the frame. The reinforcing plate extends from the mounting cavity through the through-hole to the outside of the frame. Alternatively, the thickness of the first portion is greater than the thickness of the second portion.

[0025] By employing the above solution, a reinforcing piece is placed at the connection point between the spring and the frame, or the thickness at this connection point is increased (which can be understood as making the spring uneven in thickness). When the smart glasses are worn and the temples are extended outwards, the deformation of the spring at the frame connection point can be reduced. This reduces the risk of the spring abutting against the sidewall of the frame's through-hole due to excessive deformation at the frame connection point, thereby enabling the spring to provide a stable and reliable elastic clamping force.

[0026] In one possible implementation, the wire-blocking member extends along the length of the spring, and has a first end and a second end along its extension direction. The first end of the wire-blocking member is located inside the frame. The wire-blocking member is fixedly connected to the spring, and when the temple is in the extended state and the smart glasses are worn, the temple and the second end of the wire-blocking member abut against each other.

[0027] With the above solution, the wire shield extends along the length of the spring piece, and the first end of the wire shield along its extension direction is located inside the frame, while the second end abuts against the temple when the temple is in the unfolded state. This can maximize the protection of the signal transmission line by wrapping it with the wire shield, while also making the smart glasses look more continuous and aesthetically pleasing.

[0028] Furthermore, the shim extends into the frame, which increases the structural strength of the hinge device at the frame through-hole and reduces the deformation of the spring at the frame connection point.

[0029] Furthermore, the wire shield is fixedly connected to the spring clip. When the temple is in the extended state and the smart glasses are worn, the temple and the second end of the wire shield abut against each other. This abutment point allows for relatively stable force transmission between the temple and the spring clip. For example, when the temple is extended outwards (i.e., expanded), the temple, by driving the wire shield, forces the spring clip to undergo elastic deformation, generating an elastic force inwards. This elastic force is transmitted to the temple through the wire shield, providing the temple with an elastic clamping force to the wearer's head, ensuring reliable and comfortable wear. Simultaneously, the simple structure and small footprint allow for thinner temples and hinge mechanisms, further contributing to a slimmer, lighter design for the smart glasses and enhancing the user experience.

[0030] In one possible implementation, when the transmission line segment passing through the hinge device in the signal transmission line is encased within the shielding member, the spring is also encased within the shielding member and fixedly connected to it. The shielding member primarily serves to encase the spring and the signal transmission line, providing good protection for both.

[0031] In one possible implementation, when the transmission line segment passing through the hinge device in the signal transmission line is enclosed within a structure composed of a spring and a wire shield, the wire shield is fixedly connected to the inner or outer side of the spring, and the wire shield and the spring surround to form a receiving space for the signal transmission line to pass through. This method of forming a receiving space for the signal transmission line by the spring and the wire shield results in a simple structure, and while ensuring elastic clamping force, it also allows for a thinner hinge device and a smaller overall size.

[0032] In one possible implementation, the cross-sections of the spring and the wire-shielding member are U-shaped, and in the thickness direction of the hinge device, the openings of the U-shape in the spring and the U-shape in the wire-shielding member face each other. This ensures the reliability of the fixation between the spring and the wire-shielding member.

[0033] In one possible implementation, the wire shield is made of soft rubber. Soft rubber has good elasticity and flexibility. When subjected to the elastic force applied by the spring, the soft rubber can undergo elastic deformation. Its structure itself is not easy to crack, resulting in high structural reliability and a long service life.

[0034] In one possible implementation, the wire shield is made of one of silicone, thermoplastic polyurethane elastomer, and polypropylene plastic.

[0035] In one possible implementation, the signal transmission line is fixedly connected to a spring and / or a shield.

[0036] In one possible implementation, the signal transmission line is an FPC or a cable.

[0037] In one possible implementation, the spring is designed as an integrated structure, which is simple, low-cost, occupies less space, and can be made thinner, which is conducive to the lightweight design of smart glasses.

[0038] In one possible implementation, the spring is made of metal. When the spring is used as an exterior component of smart glasses, it can provide finishes such as high-gloss metallic or matte metallic.

[0039] In one possible implementation, the frame includes two temples, one end of each temple being rotatably connected to the corresponding end of the frame via a hinge device. The signal transmission line passing through each hinge device is either the same signal transmission line or two independent signal transmission lines.

[0040] A second aspect of this application provides a hinge device for smart glasses. The hinge device includes a spring and a wire shield. A first end of the spring along its length is fixedly connected to the frame of the smart glasses, and a second end of the spring along its length is rotatably connected to the temple of the smart glasses. The wire shield is installed on the spring, and the wire shield, or a structural member consisting of the wire shield and the spring, is used to wrap the signal transmission line of the smart glasses. When the hinge device is installed between the frame and the temple, the temple is in the extended state, and the smart glasses are worn, the hinge device and the temple abut against each other, and the elastic deformation of the spring provides the temple with an elastic clamping force towards the wearer's head.

[0041] The hinge device provided in this application embodiment can be applied to smart glasses. The hinge device's spring contacts enable temple folding while simultaneously providing an elastic clamping force to hold the wearer's head. Compared to existing hinge devices that simultaneously incorporate springs, mounting bases (i.e., the mounting structure corresponding to the springs), brackets, and pivots to achieve the same function, this application embodiment eliminates the need for additional mounting bases, brackets, and pivots as fulcrums, significantly reducing the number of parts, simplifying assembly relationships, resulting in a simpler structure and greatly reducing assembly difficulty. Furthermore, due to the significantly reduced number of parts in the hinge device, its weight and volume can also be greatly reduced. This, in turn, allows for a significant reduction in the thickness and volume of the hinge device in the smart glasses, as well as the thickness and volume at the connection between the temples / frame and the hinge device, thus contributing to a thinner and lighter design for smart glasses.

[0042] Furthermore, by wrapping the transmission line segment passing through the hinge device in the signal transmission line with a shielding component or a structural component consisting of a shielding component and a spring, the signal transmission line can be protected from external damage to ensure the reliability of electrical signal transmission. At the same time, the signal transmission line can be hidden inside, making the hinge device and smart glasses look continuous and aesthetically pleasing. Attached Figure Description

[0096] The terms "parallel," "perpendicular," and "identical" (e.g., identical length, identical width, etc.) mentioned in the embodiments of this application are all relative to the current technological level, and not absolute and strict definitions in a mathematical sense. There can be a deviation within a predetermined angular range between two mutually parallel or perpendicular components. In one embodiment, the predetermined angle is 10°, and for example, the deviation can be within the range of ±5°.

[0097] In the description of the embodiments of this application, it should be understood that "electrical connection" in the embodiments of this application can be understood as physical contact and electrical conduction between components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines that can transmit electrical signals, such as copper foil of printed circuit board (PCB) or wires.

[0098] Relative / Relative Setting: A and B being relative to each other can mean that A and B are positioned face to face. For example, when two components are positioned relative to each other, at least a portion of the two components overlap in a certain direction.

[0099] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0100] This application provides a smart glasses embodiment. The specific type of smart glasses is not limited, and may include, but is not limited to, smart audio glasses (i.e., smart glasses with audio functionality), mobile phone accessory glasses, smart assistant glasses, smart glasses with display functions such as augmented reality (AR), virtual reality (VR), or mixed reality (MR), etc.

[0101] Please see Figures 1-2 , Figure 1 This is an exploded view of the smart glasses according to an embodiment of this application. Figure 2 This is a top view of the smart glasses according to an embodiment of this application.

[0102] like Figure 1 and Figure 2 As shown, this application provides a smart glasses 1, including a frame 3 and lenses 2. The frame 3 is used to construct the overall shape of the smart glasses 1, and to install and accommodate various optical and electronic devices. The lenses 2 are optical devices mounted on the frame 5 of the frame 3, and are light-transmitting, allowing the wearer to see through the lenses 2. The lenses 2 may have functions such as vision correction and blue light blocking, but this application does not limit this.

[0103] It should be noted that the embodiments of this application do not limit the specific structure of the frame 3, the number of lenses 2, their mounting position on the frame 3, or the mounting method. The following uses optical glasses as an example to illustrate the possible structure of the frame 3.

[0104] like Figure 1 and Figure 2 As shown, the frame 3 includes a frame 5 and temples 4. Lenses 2 are mounted on the frame 5. It should be noted that the frame 3 may include two temples 4, or it may have only one temple 4; this embodiment does not limit this. Figures 1-2 As shown, in this embodiment of the application, the frame 3 takes two temples 4, one on the left and one on the right, as an example. One end 40 of each temple 4 is rotatably connected to the left and right ends of the frame 5 via corresponding hinge devices 7. Alternatively, it can be understood that one end 40 of each temple 4 is rotatably connected to the corresponding end 50 of the frame 5 via a hinge device 7 (for example, one end 40 of the left temple 4 is rotatably connected to the left end of the frame 5 via the left hinge device 7, and one end 40 of the right temple 4 is rotatably connected to the right end of the frame 5 via the right hinge device 7), so that each temple 4 can switch between an unfolded state and a folded state.

[0105] When each temple 4 is in the like Figure 2In the unfolded state, the temple 4 and frame 5 form a certain angle, allowing the temple 4 to be held close to the wearer's ear for easy wearing. In one possible implementation, when the temple 4 is in the unfolded state, the angle between the temple 4 and frame 5 is 90°. It should be noted that the angles illustrated in this embodiment are allowed to have slight deviations. For example, when the temple 4 is in the unfolded state, the angle between it and the frame 5 can be 90°, or approximately 90°, such as 85°, 87°, 93°, or 95°, etc. Other angles can be understood in the same way later. When the temple 4 is switched to the folded state (not shown in the figure), the angle between the temple 4 and frame 5 is approximately 0°, and the two temples 4 and frame 5 are stacked sequentially, making it easy to store the smart glasses 1 in the glasses case.

[0106] It should be noted that the above structure is merely an example. In some possible implementations, the smart glasses 1 may also be equipped with a temple 4. This application embodiment does not limit this.

[0107] Those skilled in the art will understand that the hinge devices 7 respectively provided between the two temples 4 and the frame 5 can have the same structure or different structures (for example, one hinge device 7 adopts the following...). Figure 4a The structure shown has another hinge device 7 that uses the following design: Figure 14a (Structure shown). The two hinge devices 7 can be arranged symmetrically or asymmetrically. A temple 4 can be rotatably connected to the frame 5 via the hinge device 7 described in the embodiments of this application. The hinge device 7 provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings; further details will not be provided here.

[0108] It is understood that the left and right directions described in this article are relative to the wearer. When the wearer wears the smart glasses 1 on their head, the left and right temples 4 can be positioned on the wearer's left and right ears respectively. The frame 5 and the lens 2 are located in front of the wearer. The left hinge device 7 and the left end of the frame 5 are located on the wearer's left side, and the right hinge device 7 and the right end of the frame 5 are located on the wearer's right side. The end 40 of the temple 4 mentioned above refers to the end of the temple 4 along its length that is close to the frame 5.

[0109] For ease of understanding, the directions of the temple 4, the frame 5, and the hinge device 7 mentioned in this article will be explained uniformly below.

[0110] like Figure 1 and Figure 2 As shown, the length direction L2 of the temple can be understood as the direction of the extension path of the temple 4, for example, as... Figure 1The bending direction of the temple 4 is shown. The width direction W2 of the temple can be understood as the direction perpendicular to the length direction L2 of the temple, and the vertical direction of the temple 4 when the smart glasses 1 is worn. The thickness direction H2 of the temple can be understood as the direction perpendicular to both the length direction L2 and the width direction W2 of the temple, and the horizontal direction of the temple 4 when the smart glasses 1 is worn. It can also be understood as the arrangement direction of the two temples 4 when they are in the unfolded state, for example, as... Figure 2 As shown, when each temple 4 is in the unfolded state, the two temples 4 are positioned opposite each other in the thickness direction H2 of the temple.

[0111] The length direction L1 of the frame can be understood as the left-right direction of the frame 5 when the smart glasses 1 are worn. The width direction W1 of the frame can be understood as the up-down direction of the frame 5 when the smart glasses 1 are worn. The thickness direction H1 of the frame can be understood as the front-back direction of the frame 5 when the smart glasses 1 are worn.

[0112] The length direction of hinge device 7 can be understood as the direction of the extension path of hinge device 7, for example, as Figure 1 and Figure 2 The bending direction of the hinge device 7 shown is the direction in which it extends from the frame 5 to the temple 4. The width direction of the hinge device 7 can be understood as the vertical direction of the hinge device 7 when the smart glasses 1 are worn. The thickness direction of the hinge device 7 can be understood as the direction in which the inner and outer sides of the hinge device 7 are positioned opposite each other when the smart glasses 1 are worn. The inner side of the hinge device 7 can be understood as the side of the hinge device 7 facing the wearer's head when the smart glasses 1 are worn, and the outer side of the hinge device 7 can be understood as the side of the hinge device 7 away from the wearer's head when the smart glasses 1 are worn.

[0113] It should be noted that the length direction of the spring piece 71 and the length direction of the wire-blocking member 72 described below correspond to the length direction of the hinge device 7, the thickness direction of the spring piece 71 and the thickness direction of the wire-blocking member 72 correspond to the thickness direction of the hinge device 7, and the width direction of the spring piece 71 and the width direction of the wire-blocking member 72 correspond to the width direction of the hinge device 7.

[0114] The above text provides a brief description of the basic structure of smart glasses 1. The following text will explain the smart functions of smart glasses 1 and the transmission method of electrical signals.

[0115] It should be noted that, as Figure 2As shown, the smart glasses 1 may also include various electronic components (not shown in the figure) and circuit boards (not shown in the figure). The number of circuit boards can be one or more, such as a main board and a sub-board. Each electronic component can be integrated onto the circuit board, or it can be set up separately and then connected to the circuit board or other components via wired, wireless, or other means. For example, the electronic components may include a processor, battery, speaker, horn, antenna system, display screen, optical engine, camera module, etc., without specific limitations. The battery serves as the power source for the smart glasses 1, and its specific number and location are not limited. For example, there may be two batteries, located on the left and right temples 4 respectively. A charging interface can be provided on the temple 4 corresponding to the battery for charging. The processor can be used to analyze signals, process data, generate program instructions, and control other electronic components to perform operations, such as controlling the operation of the speaker, horn, optical engine, camera module, etc. A processor may include one or more processing units, such as a central processing unit (CPU), an application processor (AP), a modem processing unit, a graphics processing unit (GPU), an image signal processor (ISP), a video processing unit (VPU), etc. It may also include a controller, memory, a video codec, a digital signal processor (DSP), etc.

[0116] The speaker and horn are the audio devices for the smart glasses 1. The speaker is used to play sound, and the horn is used to pick up sound. The wearer can interact with the smart glasses 1 via voice through the audio devices. The number of speakers and horns is unlimited; for example, one speaker and one horn can be installed on the left and right temples 4 respectively. The antenna system is used to transmit and receive wireless signals to achieve communication functionality.

[0117] It should be noted that some of the electronic components mentioned above, or some electronic components and some circuit boards, can be integrated into the temple 4 to realize some intelligent functions of the smart glasses 1, such as audio output, AR display, VR display, information prompts, charging and discharging, etc. That is to say, the temple 4 is provided with a first electronic unit 41, which includes electronic components, or includes electronic components and circuit boards. It should be noted that the first electronic unit 41 is located inside the temple 4, indicated by a dashed box, or the first electronic unit 41 can also be disposed outside the temple 4, or a part of the electronic components of the first electronic unit 41 can be disposed inside the temple 4, and another part of the electronic components of the first electronic unit 41 can be disposed outside the temple 4. This application does not limit this.

[0118] like Figure 2 As shown, in one possible implementation, the electronic components of the first electronic unit 41 may include a battery (not shown) and an audio device (not shown, but may include, for example, a speaker). The battery can power other electronic components in the first electronic unit 41. When the frame 5 and lens 2 are provided with a second electronic unit 51, the battery can also power them via a signal transmission line 6, which extends from the frame 5 through the hinge device 7 to the temple 4. It should be noted that the above-mentioned electronic components can all be those known in the prior art, and will not be described in detail here. When the frame 3 includes two temples 4, the electronic components included in the first electronic unit 41 in the two temples 4 may be the same or different, and this application embodiment does not limit this.

[0119] like Figure 2 As shown, in one possible implementation, the first electronic unit 41 may further include a circuit board (not shown) and a processor (not shown) integrated on the circuit board. The processor is capable of generating control signals to process information and execute the wearer's instructions. In other possible implementations, the first electronic unit 41 may not include a circuit board and / or a processor; this embodiment does not impose any limitations on this.

[0120] Those skilled in the art will understand that some smart glasses 1 (e.g., VR glasses, AR glasses) need to transmit information to the wearer's eyes; therefore, electronic units also need to be installed within the frame 5. For example... Figure 2 As shown, in one possible implementation, the frame 5 is provided with a second electronic unit 51, which may include a display unit capable of displaying images, enabling the wearer to receive image information. For example, an optical engine (not shown) is provided at the left and right ends of the frame 5. The optical engine can transmit image information to be displayed to the lens 2, and the lens 2 can display the image information transmitted by the optical engine, so that the image information can be seen by the wearer.

[0121] like Figure 2 As shown, in one possible implementation, the second electronic unit 51 may further include a circuit board (not shown) and a processor (not shown) integrated on the circuit board. The processor is capable of generating control signals to process information and execute the wearer's instructions. In other possible implementations, the second electronic unit 51 may not include a circuit board and / or a processor; this embodiment does not impose any limitations on this.

[0122] like Figure 2As shown, in one possible implementation, a signal transmission line 6 is provided within the frame 3. The signal transmission line 6 extends from the frame 5 through the corresponding hinge device 7 to the corresponding temple 4. For example, the signal transmission line 6 on the left side extends from the left end of the frame 5 through the left hinge device 7 to one temple 4 on the left side, and the signal transmission line 6 on the right side extends from the right end of the frame 5 through the right hinge device 7 to one temple 4 on the right side. It should be noted that the signal transmission line 6 passing through each hinge device 7 can be the same signal transmission line or two independent signal transmission lines; this embodiment does not limit this.

[0123] Furthermore, the specific type of the signal transmission line 6 is not limited; for example, it can be an FPC (Flexible Printed Circuit) or a cable. Those skilled in the art will understand that the signal transmission line 6 can be used to transmit power signals and communication signals, or it can be used to transmit either power signals or communication signals; this application embodiment does not impose any limitations in this regard.

[0124] like Figure 2 As shown, in one possible implementation, in each temple 4, the first electronic unit 41 disposed on the temple 4 is electrically connected to the second electronic unit 51 disposed on the frame 5 via a corresponding signal transmission line 6. For example, data, video, and other signals emitted by the circuit board and processor in the first electronic unit 41 can be transmitted to the second electronic unit 51 and received by the wearer. Similarly, audio and other signals emitted by the circuit board and processor in the second electronic unit 51 can be transmitted to the second electronic unit 51 and received by the wearer. In other possible implementations, the second electronic unit 51 may not be disposed in the frame 5; this embodiment does not impose any limitations on this.

[0125] like Figure 2 As shown, in one possible implementation, the first electronic units 41 located on the two temples 4 can be electrically connected via the signal transmission line 6 on the left, the frame wiring, and the signal transmission line 6 on the right, enabling signal transmission between the two first electronic units 41. This allows signals emitted from the first electronic unit 41 on one temple 4 to be transmitted to the first electronic unit 41 on the other temple 4. It should be noted that the frame wiring can be independently configured from the signal transmission lines 6 on the left and right, or it can be the same signal transmission line as the left and / or right signal transmission lines 6. This embodiment does not impose any limitations on this. In other possible implementations, the first electronic units 41 located on the two temples 4 may not be electrically connected, and this embodiment does not impose any limitations on this.

[0126] like Figure 2As shown, in one possible implementation, to further reduce the weight of the smart glasses 1, the first electronic unit 41 on one temple 4 may include a circuit board and a processor integrated on the circuit board. The first electronic units 41 located on the two temples 4 are electrically connected via frame wiring, enabling the audio device (belonging to the first electronic unit 41) in one temple 4 to communicate with the processor on the other temple 4. In other possible implementations, the first electronic unit 41 on one of the two temples 4 may be electrically connected to the second electronic unit 51 in the frame 5 via a signal transmission line 6, while the first electronic unit 41 on the other temple may not be electrically connected to the second electronic unit 51. This application embodiment does not limit this.

[0127] The preceding text mainly introduced the basic structural components and intelligent functions of the smart glasses 1. The following text will take a hinge device 7 as an example to explain in detail its specific structure and connection method with the frame 5 and temples 4. It should be noted that the other hinge device 7 can also adopt the structure described below.

[0128] Please see Figures 3a-6c , Figures 3a-3b This is a schematic diagram of the structure of the hinge device and the connection between the temple and the frame in the smart glasses of this application embodiment. Figures 4a-4b This is a schematic diagram of one embodiment of the hinge device in the smart glasses of this application. Figure 5 This is a cross-sectional view of the connection between the hinge device and the temple and frame in the smart glasses of this application embodiment. Figures 6a-6c This is a schematic diagram of the structure of the hinge device and the connection part of the temple in the smart glasses of this application embodiment.

[0129] like Figures 3a-5 As shown, the hinge device 7 includes a spring piece 71 and a wire-blocking member 72, with the wire-blocking member 72 mounted on the spring piece 71. A first end 71A of the spring piece 71 along its length is fixed to one end 50 of the frame 5, and a second end 71B of the spring piece 71 along its length is rotatably connected to one end 40 of the temple 4 (for example, the second end 71B of the spring piece 71 can rotate relative to the temple 4 about a first axis O1), so that one end 40 of the temple 4 is rotatably connected to one end 50 of the frame 5 via the spring piece 71. It should be noted that the spring piece 71 can be understood as the main load-bearing component of the hinge device 7, constituting the main body of the hinge device 7. It provides a connection structure for connecting the frame 5 and the temple 4 to achieve the folding function of the temple 4, and also provides an elastic clamping force to the temple 4 when the temple 4 is in the unfolded state and the smart glasses 1 are worn, to securely clamp the wearer's head.

[0130] It should be noted that the length direction of the shrapnel 71 can be understood as the direction of its extension path, for example, as...Figure 4b and Figure 5 The bending direction of the spring piece 71 shown is the direction in which it extends from the frame 5 to the temple 4. The width direction of the spring piece 71 can be understood as the vertical direction of the spring piece 71 when the smart glasses 1 are worn. The thickness direction of the spring piece 71 can be understood as the direction in which the inner and outer sides of the spring piece 71 are positioned relative to each other when the smart glasses 1 are worn. The inner side of the spring piece 71 can be understood as the side of the spring piece 71 facing the wearer's head when the smart glasses 1 are worn, and the outer side of the spring piece 71 can be understood as the side of the spring piece 71 away from the wearer's head when the smart glasses 1 are worn.

[0131] Those skilled in the art will understand that the embodiments of this application do not limit the fixed connection method between the first end 71A of the spring 71 and the frame 5. For example, a fixed connection can be achieved by fastening with fasteners 505 (such as screws, bolts, etc.) or by welding. The embodiments of this application do not limit the relative rotatable connection method between the second end 71B of the spring 71 and the temple 4. For example, relative rotation can be achieved through a connecting shaft. The specific connection methods that can be used between the spring 71 and the frame 5 and temple 4 will be described in detail below with reference to the accompanying drawings, and will not be elaborated further here.

[0132] like Figures 4a-5 As shown, it should be noted that the wire-blocking member 72 and the spring piece 71 can be fixedly connected or not fixedly connected, and this embodiment does not limit this. Furthermore, the relative positional relationship between the wire-blocking member 72 and the spring piece 71 is not limited. The specific structure of the wire-blocking member 72 and the related details of the mating structure between the wire-blocking member 72 and the spring piece 71 will not be elaborated upon here, but will be discussed in detail below. Figures 13a-15b Detailed explanation follows.

[0133] like Figure 5 As shown, in one possible implementation, the transmission line segment of the signal transmission line 6 that passes through the hinge device 7 is encased within the wire shield 72. See also... Figure 15a In another possible implementation, the transmission line segment of the signal transmission line 6 that passes through the hinge device 7 is enclosed within a structural member consisting of the spring 71 and the wire shield 72. For example, the transmission line segment of the signal transmission line 6 that passes through the hinge device 7 is enclosed within a receiving space 721 formed by the spring 71 and the wire shield 72.

[0134] In the smart glasses 1 provided in this application embodiment, the signal transmission line 6 is used to transmit electrical signals between the temple 4 and the frame 5. The transmission line segment passing through the hinge device 7 in the signal transmission line 6 is wrapped by the wire shield 72 or a structural member composed of the wire shield 72 and the spring piece 71, which can protect the signal transmission line 6 from external damage and ensure the reliability of electrical signal transmission. At the same time, the signal transmission line 6 can also be hidden inside, making the appearance of the smart glasses 1 continuous and beautiful.

[0135] Furthermore, such as Figure 5 As shown, the hinge device 7 is equipped with a spring piece 71. The first end 71A of the spring piece 71 is fixed to the frame 5, and the second end 71B of the spring piece 71 is rotatably connected to the temple 4, thereby allowing the temple 4 to switch between an unfolded state and a folded state, thus realizing the folding function of the temple 4. When the temple 4 is in the unfolded state, the temple 4 abuts against the corresponding hinge device 7, and when the smart glasses 1 is worn, the elastic deformation of the spring piece 71 provides the temple 4 with an elastic clamping force in the direction of the wearer's head. Since the temple 4 abuts against the hinge device 7, the force can be transmitted relatively stably between the temple 4 and the spring piece 71 at the point of contact between the temple 4 and the hinge device 7. When the temple 4 is in the unfolded state and the smart glasses 1 is worn, the temple 4 further expands outward relative to the frame 5 (for example, the temple 4 expands outward relative to the frame 5 along the...). Figure 5 When the movement is in the direction indicated by the left arrow, the spring piece 71 of the hinge device 7 undergoes elastic deformation under the action of the temple 4, and provides the temple 4 with an elastic clamping force towards the wearer's head (or, as can be understood, provides the temple 4 with an elastic clamping force towards the inward direction, for example, provides the frame 5 along the direction of the wearer's head). Figure 5 The elastic clamping force (in the direction indicated by the arrow on the right) provides clamping force for the entire smart glasses 1, clamping the wearer's head to ensure the stability and reliability of the smart glasses 1 when worn, thereby increasing the wearer's compatibility and comfort.

[0136] It should be noted that, as Figure 5 As shown, and in combination Figure 2 It can be understood that the temple 4 further expands outward relative to the frame 5, which can be interpreted as the temple 4 moving a certain distance away from the wearer's head relative to the frame 5 along the length direction L1 of the frame. It can also be interpreted as the two temples 4 moving a certain distance away from each other in the case of having two temples 4.

[0137] Furthermore, such as Figures 5-6cAs shown, this application embodiment does not specifically limit the position where the temple 4 and the hinge device 7 abut against each other. As long as the force can be transmitted relatively stably between the temple 4 and the spring piece 71 at the position where they abut against each other, so that when the temple 4 is in the unfolded state and the smart glasses 1 is worn, the movement of the temple 4 toward its outer side can cause the spring piece 71 to undergo elastic deformation and provide the temple 4 with an elastic clamping force toward the wearer's head, it falls within the scope of this application embodiment. The position where the temple 4 and the hinge device 7 abut against each other may, for example, include the position where the wire-blocking member 72 abuts against the temple 4 (e.g., Figures 6a-6c The position indicated by the dashed circle in the middle, the position where the spring piece 71 is rotatably connected to the temple 4 (as shown in the image). Figure 11b The positions of the first connecting shaft 7134 and the second connecting shaft 7135 will be explained in detail below with reference to the attached drawings, and will not be discussed further here.

[0138] As can be seen from the above, the hinge device 7 of this application embodiment can realize the folding function of the temple 4 through the spring piece 71, while providing an elastic clamping force to clamp the wearer's head. Compared with the existing hinge device that simultaneously sets up a spring, a mounting base (i.e., the mounting structure corresponding to the spring), a bracket and a pivot to achieve the above functions, this application embodiment does not require additional mounting base, bracket and pivot as the fulcrum of the bracket, which greatly reduces the number of parts, simplifies the assembly relationship of parts, makes the structure simpler and greatly reduces the assembly difficulty.

[0139] In addition, because the number of parts in the hinge device 7 is greatly reduced, the weight and volume of the hinge device 7 can also be greatly reduced. Consequently, the thickness and volume of the hinge device 7 of the smart glasses 1, as well as the thickness and volume of the connection between the temple 4 and the frame 5 and the hinge device 7, can also be greatly reduced, thus helping the smart glasses 1 to achieve a thin and light design.

[0140] Therefore, the smart glasses 1 provided in this application embodiment has a simple structure, is easy to assemble, and has a low production cost, which is conducive to the realization of a thin and light design for the smart glasses 1.

[0141] It should be noted that the first end 71A of the spring 71 can be installed inside or outside the frame 5, and this application embodiment does not limit this. The relative positional relationship between the spring 71 and the frame 5 and the possible connection methods will be described below with reference to the accompanying drawings.

[0142] Please see Figures 7a-8b , Figures 7a-7b This is a schematic diagram of the structure of the spring piece connecting the hinge device to the frame in the smart glasses of this application embodiment. Figure 7c This is a partial structural diagram of the frame of the smart glasses in an embodiment of this application. Figures 8a-8bThis is a schematic diagram of the structure of the spring piece connecting the hinge device to the frame in the smart glasses of this application embodiment.

[0143] like Figure 5 , Figures 7a-8b As shown, in one possible implementation, the first end 71A of the spring 71 can be installed inside the eyeglass frame 5. Specifically, one end 50 of the eyeglass frame 5 has a mounting cavity 501 and a through hole 502. One end of the through hole 502 communicates with the mounting cavity 501, and the other end extends to the outer surface of one end 50 of the eyeglass frame 5. The first end 71A of the spring 71 is fixedly installed inside the mounting cavity 501 of the eyeglass frame 5, and the spring 71 extends from inside the mounting cavity 501 through the through hole 502 to the outside of the eyeglass frame 5. The part where the spring 71 connects to the eyeglass frame 5 is hidden inside the eyeglass frame 5, which can provide better protection and a more aesthetically pleasing appearance.

[0144] like Figure 5 , Figures 7a-7c As shown, in one possible implementation, the through hole 502 is located on the side of the mounting cavity 501 facing outwards from the frame 5 along the length direction L1 of the frame, and the other end of the through hole 502 extends to the outer end face 503 of one end 50 of the frame 5. In other possible implementations, the other end of the through hole 502 may also extend to other locations on the outer surface of one end 50 of the frame 5. For example, the other end of the through hole 502 may also extend to the inner side of the outer surface of one end 50 of the frame 5. The inner side of the outer surface can be understood as the surface of the outer surface of the frame 5 on the side facing the wearer's eyes in the thickness direction H1 of the frame.

[0145] It should be noted that, in order to reduce the deformation of the spring piece 71 at the connection position of the frame 5, a reinforcing piece 73 or an increase in the thickness of the connection position can be added at this connection position in this embodiment. The specific structures that can be adopted will be described in detail below with reference to the accompanying drawings.

[0146] Please see Figures 9a-10b , Figure 9a This is a three-dimensional structural schematic diagram of another embodiment of the hinge device in the smart glasses of this application. Figure 9b This is a schematic diagram of the external structure of the hinge device spring and the frame connection portion in another embodiment of the smart glasses of this application. Figure 10a This is a three-dimensional structural diagram of the hinge device spring and the frame connection portion in another embodiment of the smart glasses of this application. Figure 10b This is an exploded structural diagram of the hinge device spring and the frame connection portion in another embodiment of the smart glasses of this application.

[0147] like Figures 9a-10b As shown, and in combination Figure 7bIt is understood that, in one possible implementation, the spring 71 includes a first portion 714, a second portion 715, and a third portion 716 connected sequentially along its length. The first portion 714 includes a first end 71A of the spring 71 and extends from the mounting cavity 501 through the through hole 502 to the outside of the frame 5. The second portion 715 is located between the frame 5 and the temple 4, and the third portion 716 includes a second end 71B of the spring 71 and extends from the inside of the temple 4 through the end face 40 of the temple 4 to the outside of the temple 4. Those skilled in the art will understand that the first portion 714 can be understood as the part of the spring 71 connected to the frame 5, the third portion 716 as the part of the spring 71 connected to the temple 4, and the second portion 715 as the part of the spring 71 located outside the frame 5 and outside the temple 4. It can also be understood as the portion used to generate elastic deformation to provide an elastic clamping force to the temple 4.

[0148] like Figures 9a-10b As shown, and in combination Figure 7b It is understood that, in one possible implementation, the hinge device 7 may further include a reinforcing piece 73, which is stacked on the first portion 714 of the spring piece 71, and the first end 71A of the spring piece 71, the reinforcing piece 73, and the frame 5 are fixedly connected. The reinforcing piece 73 extends from the mounting cavity 501 through the through hole 502 to the outside of the frame 5. In one example, a fastener 505 passes through the reinforcing piece 73 and the first end 71A of the spring piece 71 and is fixed to the mounting platform 504 of the frame 5. In another possible implementation, the thickness of the first portion 714 is greater than the thickness of the second portion 715.

[0149] In this embodiment, by providing a reinforcing piece 73 at the connection point between the spring piece 71 and the frame 5, or by increasing the thickness of the spring piece 71 at the connection point (which can be understood as setting the spring piece 71 to a non-uniform thickness), the deformation of the spring piece 71 at the connection point with the frame 5 can be reduced when the smart glasses 1 is worn and the temples 4 are extended outward. This reduces the risk of the spring piece 71 abutting against the side wall of the through hole 502 of the frame 5 due to excessive deformation at the connection point, thereby enabling the spring piece 71 to provide a stable and reliable elastic clamping force.

[0150] It should be noted that the specific length of the reinforcing piece 73 extending beyond the frame 5 is not limited and can be reasonably set according to actual needs.

[0151] Furthermore, the specific material of the reinforcing piece 73 is not limited. In one possible implementation, the reinforcing piece 73 is made of metal.

[0152] Furthermore, the spring clip 71 can be configured as a single piece or as a separate piece; this application embodiment does not impose any limitation on this. For example... Figure 4b andFigure 5 As shown, in one possible implementation, the spring 71 is set as an integrated structure, which is simple in structure, low in cost, occupies less space, and can also be made thinner, which is conducive to the realization of a lightweight and thin design of smart glasses 1.

[0153] Furthermore, this application embodiment does not limit the thickness of the spring 71 and the hinge device 7, and can reasonably set them according to the required elastic clamping force, structural strength, and the lightweight design requirements of the smart glasses 1. Figure 4b and Figure 5 As shown, in one possible implementation, the thickness d1 of the spring 71 is 0.6mm-1.3mm. Correspondingly, the thickness d2 of the hinge device (which can be understood as the thickness of the structural component formed by the spring 71 and the wire-blocking member 72) is 3mm-4mm. This ensures sufficient elastic clamping force for the temple 4, facilitating a thinner and lighter design for the smart glasses 1. In other possible implementations, the thickness d1 of the spring 71 can be less than 0.6mm or greater than 1.3mm. Correspondingly, the thickness d2 of the hinge device can be less than 3mm or greater than 4mm.

[0154] It should be noted that the specific material of the spring 71 is not limited in the embodiments of this application. For example... Figure 4b and Figure 5 As shown, in one possible implementation, the spring 71 is made of metal. This provides a relatively stable elastic clamping force to the temple 4 under elastic deformation, and also ensures the structural strength at the connection points between the spring 71 and the frame 5 and temple 4. Furthermore, when the spring 71 serves as an exterior component of the smart glasses 1, it can provide aesthetic effects such as high-gloss metallic finish or matte metallic finish.

[0155] It should be noted that the specific structure of the spring 71 is not limited in the embodiments of this application.

[0156] like Figures 4a-5 As shown, and in combination Figure 8a and Figure 8b It is understood that, in one possible implementation, the spring 71 includes a first mounting arm 712, an elastic arm 711, and a second mounting arm 713 arranged sequentially along its length. The elastic arm 711 has a first end 711A and a second end 711B along its length. The first mounting arm 712 is connected to the first end 711A of the elastic arm 711, forming the first end 71A of the spring 71, and is fixedly connected to one end 50 of the frame 5. The second mounting arm 713 is connected to the second end 711B of the elastic arm 711, forming the second end 71B of the spring 71, and is rotatably connected to one end 40 of the temple 4.

[0157] The elastic arm 711 arches outwards, and when the smart glasses 1 are worn, the outer side of the elastic arm 711 is the side away from the wearer's head. The spring piece 71 is fixed to the frame 5 via the first mounting arm 712 and rotatably connected to the temple 4 via the second mounting arm 713. The elastic arm 711 provides an elastic clamping force to the temple 4 towards the wearer's head. This structure is simple, and the spring piece 71, while ensuring connection strength and elastic clamping force, can be made relatively thin, allowing the hinge device 7 to be thinner and smaller, thus better achieving the goal of making the smart glasses 1 lighter and thinner. The outer side of the elastic arm 711 can also be understood as the side of the elastic arm 711 away from the wearer's head along its thickness direction.

[0158] Furthermore, the specific structure of the elastic arm 711 is not limited. For example... Figure 7b , Figures 8a-8b As shown, in one possible implementation, the elastic arm 711 adopts a strip-shaped structure. The portion of the elastic arm 711 other than its first end 711A and second end 711B constitutes the main body 711C. The main body 711C is arc-shaped along its length (or can be understood as the main body 711C extending in an arc along its length), and the arc arches outwards towards the outer side of the elastic arm 711. This provides a more stable elastic clamping force to the wearer's head. It should be noted that the first end 711A of the elastic arm 711 can extend along a straight line, a broken line, or a curve (e.g., an arc) in its length direction, and the second end 711B of the elastic arm 711 can also extend along a straight line, a broken line, or a curve (e.g., an arc) in its length direction. This application embodiment does not limit this. In one example, as... Figure 7b and Figure 8a As shown, the first end 711A of the elastic arm 711 extends in a straight line in its length direction.

[0159] It should be noted that the relative position of the first end 711A of the elastic arm 711 to the frame 5 is not limited. For example... Figure 7b As shown, in one possible implementation, the first end 711A of the elastic arm 711 extends from inside the mounting cavity 501 through the through hole 502 to outside the frame 5. In this case, the first portion 714 mentioned above includes the first mounting arm 712 and the first end 711A of the elastic arm 711. The third portion 716 mentioned above includes the second mounting arm 713, or includes the second mounting arm 713 and the second end 711B of the elastic arm 711. In other possible implementations, the first end 711A of the elastic arm 711 may also be entirely located inside or outside the mounting cavity 501.

[0160] Furthermore, the fixing structure between the first mounting arm 712 and the frame 5 is not limited. For example... Figures 8a-8b As shown, in one possible implementation, one end 50 of the frame 5 is provided with a mounting platform 504, and the first mounting arm 712 is fixedly connected to the mounting platform 504. This allows the spring piece 71 to be installed and fixed to the frame 5 very conveniently and reliably. It should be noted that the mounting platform 504 and the frame 5 can be an integral structure or a separate structure, and this embodiment does not limit this.

[0161] The method by which the first mounting arm 712 is fixedly connected to the mounting platform 504 is not limited. For example... Figures 8a-8b As shown, in one possible implementation, the mounting platform 504 is provided with a plurality of first fixing holes 5041 spaced apart, and the first mounting arm 712 is provided with a plurality of second fixing holes 7121 corresponding to the plurality of first fixing holes 5041. A corresponding fastener 505 is inserted and fixed in each first fixing hole 5041 and the corresponding second fixing hole 7121 to fix the first mounting arm 712 to the mounting platform 504. The first mounting arm 712 of the spring piece 71 is fixed to the mounting platform 504 on the frame 5 by the fastener 505. The structure is simple, occupies little space, can make full use of the space at the end of the frame 5 to fix the spring piece 71, which further helps to achieve a thin and light design for the smart glasses 1, and the fixation is reliable and the cost is low.

[0162] It should be noted that the specific type of fastener 505 is not limited; for example, it can be a screw, bolt, etc. Figures 8a-8b As shown, in one example, the fastener 505 is a screw, and each fastener 505 passes through the second fixing hole 7121 on the first mounting arm 712 and is fixedly connected to the corresponding first fixing hole 5041, thereby fixing the first mounting arm 712 to the mounting platform 504.

[0163] Furthermore, the number of first fixing holes 5041 is not limited; for example, it can be one, two, three, or more. Correspondingly, the number of second fixing holes 7121 and the number of fasteners 505 are also not limited, and can be reasonably set according to the number of first fixing holes 5041. For example... Figures 8a-8b As shown, in one example, there are two first fixing holes 5041, which are spaced apart in the width direction W1 of the frame. The axial direction of the first fixing holes 5041 can be parallel or approximately parallel to the thickness direction H1 of the frame.

[0164] In other possible implementations, the first mounting arm 712 can also be fixedly connected to the mounting platform 504 by welding or by snap-fitting, and this application embodiment does not limit this.

[0165] like Figures 8a-8bAs shown, in one possible implementation, a positioning structure (e.g., a first positioning hole 7122, a second positioning hole 7123, a first positioning post 5042 passing through the first positioning hole 7122, and a second positioning post 5043 passing through the second positioning hole 7123) can be provided between the first mounting arm 712 and the mounting platform 504 to better position the first mounting arm 712 and improve assembly efficiency. It should be noted that in other possible implementations, a positioning structure may not be provided between the first mounting arm 712 and the mounting platform 504, and this embodiment does not impose any limitations on this.

[0166] It should be noted that the specific structural form of the positioning structure is not limited. For example... Figure 8b As shown, in one possible implementation, the mounting platform 504 is provided with a first positioning post 5042 and a second positioning post 5043 spaced apart. The first mounting arm 712 is provided with a first positioning hole 7122 and a second positioning hole 7123. The first positioning post 5042 passes through the first positioning hole 7122, and the outer wall surface of the first positioning post 5042 matches the inner wall surface of the first positioning hole 7122. The second positioning post 5043 passes through the second positioning hole 7123, and the second positioning hole 7123 is an elongated hole. When installing the spring clip 71 onto the frame 5, coarse positioning can be achieved by first inserting the first positioning post 5042 into the first positioning hole 7122, and then inserting the second positioning post 5043 into the second positioning hole 7123. By adjusting the relative position of the second positioning post 5043 with respect to the second positioning hole 7123 along its length, fine positioning is achieved by aligning the fixed position of the first mounting arm 712 with that of the mounting platform 504. Then, the first mounting arm 712 is fixed to the mounting platform 504. For example, the first fixing holes 5041 on the mounting platform 504 are aligned with the corresponding second fixing holes 7121 on the first mounting arm 712, and then the fastener 505 is inserted to complete the fixing of the first mounting arm 712 to the mounting platform 504. This allows for very convenient, quick, and accurate fixing of the spring clip 71 to the corresponding position on the frame 5.

[0167] Those skilled in the art will understand that, in other possible implementations, the first positioning hole 7122 and the second positioning hole 7123 can be provided on the mounting platform 504, and correspondingly, the first positioning post 5042 and the second positioning post 5043 can be provided on the first mounting arm 712.

[0168] Furthermore, the specific location of the first positioning hole 7122 is not limited. For example... Figure 8b As shown, in one example, the first positioning hole 7122 is located at the end of the first mounting arm 712 away from the elastic arm 711. In the case of having two second fixing holes 7121, the first positioning hole 7122 is located at the end of the two second fixing holes 7121 away from the elastic arm 711.

[0169] Furthermore, the specific location of the second positioning hole 7123 is not limited. For example... Figure 8b As shown, in one example, the second positioning hole 7123 is located between two second fixing holes 7121 in the width direction W1 of the frame.

[0170] It should be noted that the extension path of the second positioning hole 7123 in the length direction is not limited. For example... Figure 8a As shown, in one possible implementation, the second positioning hole 7123 extends along a diagonal straight line in the length direction, which is inclined relative to the length direction L1 and the width direction W1 of the frame. In one example, the diagonal straight line is also inclined relative to the line connecting the center points of the two second fixing holes 7121.

[0171] It should be noted that the specific structure of the first mounting arm 712 is not limited. For example... Figure 8b and Figure 8a As shown, in one possible implementation, the first mounting arm 712 adopts a planar sheet structure. In other possible implementations, the first mounting arm 712 may also adopt a U-shaped mounting arm structure, and this application embodiment does not limit this.

[0172] Furthermore, the relative positional relationship between the first mounting arm 712 and the elastic arm 711 is not limited. For example... Figure 8b and Figures 11a-12c As shown, in one possible implementation, in the width direction of the elastic arm 711, the first mounting arm 712 protrudes from the two opposing edges of the elastic arm 711 and forms two extensions 7124. In one example, a second fixing hole 7121 is located in one extension 7124 on one side, and another second fixing hole 7121 is located in one extension 7124 on the other side. A second positioning hole 7123 is located between the two extensions 7124. A first positioning hole 7122 is located in one of the extensions 7124. In other possible implementations, in the width direction of the elastic arm 711, the first mounting arm 712 may protrude from one edge of the elastic arm 711, aligned with or recessed relative to the other edge of the elastic arm 711; or, in the width direction of the elastic arm 711, the first mounting arm 712 may be aligned with or recessed relative to the two opposing edges of the elastic arm 711. This application embodiment does not limit this.

[0173] The above text mainly describes in detail the two-edge fixing method of the relative arrangement of the spring 71 and the frame 5. The following text will describe in detail the possible structures that can be used for the rotation of the spring 71 and the temple 4 with reference to the attached drawings.

[0174] Please see Figures 11a-11b , Figures 12a-12bThis is a schematic diagram of the structure of the hinge device and the temple connection portion in one embodiment of the smart glasses of this application. Figure 12c This is a schematic diagram of the structure of the temples and the first and second connecting shafts in the smart glasses of this application embodiment. Figure 12c This is an exploded structural diagram of the spring, the first connecting shaft, and the second connecting shaft in the smart glasses of this application embodiment.

[0175] like Figures 11a-12c As shown, in one possible implementation, the second mounting arm 713 includes a connecting arm 7131 and a first fixing arm 7132. The connecting arm 7131 is connected to the second end 711B of the elastic arm 711. The first fixing arm 7132 is connected to one side of the connecting arm 7131 along the width direction of the spring piece 71, so that the connected first fixing arm 7132 and the connecting arm 7131 form an L-shaped structure. It should be noted that, in the width direction of the spring piece 71, the first fixing arm 7132 can be connected to the upper edge of the connecting arm 7131 or the lower edge of the connecting arm 7131. The upper and lower edges of the connecting arm 7131 are arranged opposite to each other in the width direction of the spring piece 71. When the smart glasses 1 are worn, the upper edge of the connecting arm 7131 is the upper edge of the connecting arm 7131, and the lower edge of the connecting arm 7131 is the lower edge of the connecting arm 7131.

[0176] like Figures 11a-12c As shown, the first fixing arm 7132 is rotatably connected to the temple 4 via the first connecting shaft 7134, so that the second mounting arm 713 is rotatably connected to one end 40 of the temple 4. This allows for very stable and reliable rotation between the spring 71 and the temple 4, thus enabling the temple 4 to fold effectively. Furthermore, when the temple 4 is in the unfolded state, the first connecting shaft 7134 can also reliably transmit force between the temple 4 and the spring 71. For example, when the temple 4 is extended outwards (i.e., expanded), the first connecting shaft 7134 can force the spring 71 to undergo elastic deformation, generating an elastic force inwards. This elastic force can be transmitted to the temple 4 via the first connecting shaft 7134, providing the temple 4 with an elastic clamping force to the wearer's head, ensuring reliable and comfortable wear. Simultaneously, the simple structure and small footprint allow for thinner temples and hinge devices 7, further contributing to the lightweight design of the smart glasses 1 and enhancing the user experience.

[0177] It should be noted that the manner in which the first fixing arm 7132 is rotatably connected to the temple 4 via the first connecting shaft 7134 is not limited. For example... Figure 12cAs shown, in one possible implementation, the temple 4 has a first connecting hole 42, the first fixing arm 7132 has a first shaft hole 7132A, and the first connecting shaft 7134 passes through the first connecting hole 42 and the first shaft hole 7132A, wherein the axis of the first connecting shaft 7134 is located on the first axis O1. The first connecting shaft 7134 is fixedly connected to the first connecting hole 42 of the temple 4 (or it can be understood that the first connecting shaft 7134 cannot rotate relative to the first connecting hole 42), and the first connecting shaft 7134 is rotatably connected to the first shaft hole 7132A of the first fixing arm 7132. That is, the first connecting shaft 7134 is fixedly connected to the temple 4 and rotatably connected to the first fixing arm 7132. In other possible implementations, the first connecting shaft 7134 may be fixedly connected to the first shaft hole 7132A of the first fixed arm 7132, and the first connecting shaft 7134 may be rotatably connected to the first connecting hole 42 of the temple 4. That is, the first connecting shaft 7134 may be fixedly connected to the first fixed arm 7132 and rotatably connected to the temple 4.

[0178] like Figures 11a-12c As shown, in one possible implementation, the second mounting arm 713 may further include a second fixing arm 7133. The second fixing arm 7133 is connected to the other side of the connecting arm 7131 along the width direction of the spring piece 71, so that the sequentially connected first fixing arm 7132, connecting arm 7131, and second fixing arm 7133 form a U-shaped structure. The first fixing arm 7132 and the second fixing arm 7133 are arranged opposite to each other in the width direction W2 of the temple, and the opening of the U-shaped structure is arranged opposite to the connecting arm 7131 in the thickness direction H2 of the temple. Figures 11a-12c As shown, the second fixing arm 7133 is rotatably connected to the temple 4 via the second connecting shaft 7135, so that the second mounting arm 713 is rotatably connected to one end 40 of the temple 4. This enables a more stable and reliable rotation between the spring piece 71 and the temple 4, thereby better realizing the folding function of the temple 4. In other possible implementations, the second mounting arm 713 may not be provided with the second fixing arm 7133, and this embodiment does not limit this.

[0179] It should be noted that the manner in which the second fixing arm 7133 is rotatably connected to the temple 4 via the second connecting shaft 7135 is not limited. For example... Figure 12bAs shown, in one possible implementation, the temple 4 has a second connecting hole 43, the second fixing arm 7133 has a second shaft hole 7133A, and the second connecting shaft 7135 passes through the second connecting hole 43 and the second shaft hole 7133A. The axis of the second connecting shaft 7135 is on the same straight line (i.e., the first axis O1) as the axis of the first connecting shaft 7134, and this straight line is parallel or approximately parallel to the width direction W2 of the temple. The second connecting shaft 7135 is fixedly connected to the second connecting hole 43 of the temple 4 (or, in other words, the second connecting shaft 7135 cannot rotate relative to the second connecting hole 43), and the second connecting shaft 7135 is rotatably connected to the second shaft hole 7133A of the second fixing arm 7133. That is, the second connecting shaft 7135 is fixedly connected to the temple 4 and rotatably connected to the second fixing arm 7133. In other possible implementations, the second connecting shaft 7135 may be fixedly connected to the second shaft hole 7133A of the second fixed arm 7133, and the second connecting shaft 7135 may be rotatably connected to the second connecting hole 43 of the temple 4. That is, the second connecting shaft 7135 may be fixedly connected to the second fixed arm 7133 and rotatably connected to the temple 4.

[0180] Those skilled in the art will understand that the first connecting shaft 7134 and the second connecting shaft 7135 can be the same connecting shaft or two independent connecting shafts; the embodiments of this application do not impose this limitation. The structures of the first connecting shaft 7134 and the second connecting shaft 7135 can be identical; for example, each connecting shaft can adopt the following... Figure 12b The structures shown may all use screws or all use a linear shaft structure. The structures of the first connecting shaft 7134 and the second connecting shaft 7135 may also differ; for example, one of the connecting shafts may use... Figure 11b The structure shown in the diagram has another connecting shaft that uses a screw or optical shaft.

[0181] like Figures 12b-12c As shown, and in combination Figures 5-6c It is understood that, in one possible implementation, each of the first connecting shaft 7134 and the second connecting shaft 7135 includes a body portion 7136A, the outer peripheral surface of which is provided with an outwardly protruding boss 7136B and an inwardly recessed limiting groove 7136C.

[0182] In one example, the body portion 7136A of the first connecting shaft 7134 passes through the first connecting hole 42 of the temple 4 and the first shaft hole 7132A of the first fixing arm 7132. The wall of the first connecting hole 42 has a recessed first groove 421, and the boss 7136B of the first connecting shaft 7134 is engaged in the first groove 421 to restrict the relative rotation between the first connecting shaft 7134 and the first connecting hole 42 of the temple 4, preventing relative rotation. Furthermore, the body portion 7136A can rotate relative to the first shaft hole 7132A of the first fixing arm 7132. Further, a limiting ring 7137 is engaged at the limiting groove 7136C of the first connecting shaft 7134, which restricts the movement of the first connecting shaft 7134 along its axial direction relative to the first connecting hole 42 of the temple 4 and the first shaft hole 7132A of the first fixing arm 7132.

[0183] The body portion 7136A of the second connecting shaft 7135 passes through the second connecting hole 43 of the temple 4 and the second shaft hole 7133A of the second fixing arm 7133. The wall surface of the second connecting hole 43 has a recessed second groove 431, and the boss 7136B of the second connecting shaft 7135 is engaged in the second groove 431 to restrict the relative rotation between the second connecting shaft 7135 and the second connecting hole 43 of the temple 4, preventing relative rotation. Furthermore, the body portion 7136A can rotate relative to the second shaft hole 7133A of the second fixing arm 7133. Further, a limiting ring 7137 is engaged at the limiting groove 7136C of the second connecting shaft 7135, which restricts the movement of the second connecting shaft 7135 along its axial direction relative to the second connecting hole 43 of the temple 4 and the second shaft hole 7133A of the second fixing arm 7133.

[0184] The above text mainly describes in detail the specific structure that the spring 71 can adopt and the connection method that the spring 71 can use with the frame 5 and the temple 4. The following text will describe in detail the cooperation method between the wire shield 72 and the spring 71 and the signal transmission line 6, as well as the specific structure of the wire shield 72, with reference to the attached drawings.

[0185] It should be noted that the relative positional relationship between the wire-blocking component 72 and the spring piece 71 is not limited. For example... Figures 5-6c As shown, in one possible implementation, the wire-blocking member 72 extends along the length direction of the spring 71, and has a first end 72A and a second end 72B along its extension direction. The first end 72A of the wire-blocking member 72 is located inside the frame 5. The wire-blocking member 72 is fixedly connected to the spring 71, and when the temple 4 is in the extended state and the smart glasses 1 is worn, the temple 4 abuts against the second end 72B of the wire-blocking member 72.

[0186] The wire shield 72 extends along the length of the spring piece 71, with its first end 72A located inside the frame 5 and its second end 72B abutting against the temple 4 when the temple 4 is in the unfolded state. This maximizes the protection of the signal transmission line 6 by wrapping it with the wire shield 72, while also making the smart glasses 1 look more continuous and aesthetically pleasing. Furthermore, the wire shield 72 extends into the frame 5, increasing the structural strength of the hinge device 7 at the through hole 502 in the frame 5 and reducing the deformation of the spring piece 71 at the connection point in the frame 5. It should be noted that in other possible implementations, the wire shield 72 may not extend into the frame 5; this embodiment does not impose such a limitation.

[0187] Furthermore, such as Figures 6a-6c As shown, the wire shield 72 is fixedly connected to the spring 71. When the temple 4 is in the extended state and the smart glasses 1 is worn, the temple 4 and the second end 72B of the wire shield 72 abut against each other (as shown). Figures 13a-13c At the location indicated by the dotted circle, force can be reliably transmitted between the temple 4 and the spring 71 at this contact point. For example, when the temple 4 is extended outwards (i.e., expanded), the temple 4 drives the suture 72, which in turn forces the spring 71 to undergo elastic deformation and generate an elastic force inwards. This elastic force can be transmitted to the temple 4 through the suture 72, thereby providing the temple 4 with an elastic clamping force to the wearer's head, ensuring reliability and comfort. Simultaneously, the simple structure and small footprint allow for thinner temples 4 and hinge devices 7, further contributing to a slimmer design for the smart glasses 1 and enhancing the user experience. In other possible implementations, the second end 72B of the suture 72 may not extend to the contact point with the temple 4; this embodiment does not impose such limitations.

[0188] It should be noted that the material of the wire shielding member 72 is not limited; for example, it can be a soft rubber material or a hard rubber material. In one possible implementation, the wire shielding member 72 is made of soft rubber material. Soft rubber material has good elasticity and flexibility. When subjected to the elastic force applied by the spring 71, the soft rubber material can undergo elastic deformation. Its structure itself is not easy to crack, resulting in high structural reliability and a long service life.

[0189] It should be noted that soft rubber materials refer to materials with a soft feel. These materials can be soft plastics or soft rubbers. For example, soft rubber materials can include silicone, rubber, silicone rubber, thermoplastic polyurethane elastomer rubber (also known as thermoplastic polyurethane rubber, abbreviated as TPU), TPE (Thermoplastic Elastomer, also known as synthetic rubber), soft PVC (Polyvinyl chloride), PE (Polyethylene), EVA (Ethylene Vinyl Acetate Copolymer), etc.

[0190] In one example, the material of the wire shield 72 is one of silicone, thermoplastic polyurethane elastomer (also known as thermoplastic polyurethane rubber, abbreviated as TPU), and polypropylene plastic (abbreviated as PP).

[0191] In another possible implementation, the wire shield 72 can be made of a rigid plastic material, such as polycarbonate (PC). Rigid plastic materials include PS (polystyrene, commonly known as rigid plastic, a transparent, glass-like material), ABS (acrylonitrile-butadiene-styrene copolymer, commonly known as ABS rigid plastic), rigid PVC (polyvinyl chloride), etc.

[0192] It should be noted that the method of fixing the spring clip 71 and the wire-blocking member 72 is not limited. The following describes the possible structural forms in conjunction with the attached drawings.

[0193] Please see Figure 13a , Figure 13b This is a three-dimensional structural diagram of the hinge device wire shield and the frame in one embodiment of the smart glasses of this application. Figure 13c This is a partial structural diagram of the hinge device in one embodiment of the smart glasses of this application, cut along its cross-section. Figure 5 This is a partial structural schematic diagram of the hinge device in one embodiment of the smart glasses of this application, cut along its longitudinal section.

[0194] like Figures 13a-13c As shown, and in combination Figure 5It is understood that, in one possible implementation, the transmission line segment of the signal transmission line 6 passing through the hinge device 7 is enclosed within the shielding member 72, and the spring piece 71 is also enclosed within the shielding member 72 and fixedly connected to it. The shielding member 72 primarily serves to enclose the spring piece 71 and the signal transmission line 6, providing good protection for both. In this case, the spring piece 71 can be understood as an internal component, enclosed within the shielding member 72 and not exposed.

[0195] It should be noted that the signal transmission line 6 can be fixedly connected to the spring 71 and the wire shield 72, or it can be not fixedly connected to them; this embodiment does not impose any limitations on this. In one possible implementation, the signal transmission line 6 is fixedly connected to the spring 71 and the wire shield 72. In another possible implementation, the signal transmission line 6 is fixedly connected to either the spring 71 or the wire shield 72.

[0196] like Figures 13a-13c As shown, and in combination Figures 14a-15b It is understood that, in one example, the shield 72 encloses the spring 71 and the signal transmission line 6, and the shield 72 is made of a soft rubber material, such as silicone or thermoplastic polyurethane elastomer.

[0197] It should be noted that the assembly method of the wire shield 72, the spring 71, and the signal transmission line 6 is not limited. In one assembly method, the signal transmission line 6 and the spring 71 can be fixed together first, and then a ring of soft rubber material can be wrapped around the outside of the fixed signal transmission line 6 and the spring 71 to form the wire shield 72, which serves to protect the signal transmission line 6 and ensure a smooth appearance. In another assembly method, a ring of soft rubber material can be wrapped around the outside of the spring 71 to form the wire shield 72. A gap can be left during the wrapping process, so that the formed wire shield 72 has a hole, and then the signal transmission line 6 can pass through the hole.

[0198] Please see Figures 14a-14b , Figure 15a This is a schematic diagram of another embodiment of the hinge device in the smart glasses of this application. Figure 15b This is a partial structural schematic diagram of the hinge device in another embodiment of the smart glasses of this application, cut along its longitudinal section. Figures 14a-15b This is a partial structural diagram of the hinge device in another embodiment of the smart glasses of this application, cut along its cross-section.

[0199] like Figure 15bAs shown, in one possible implementation, the transmission line segment of the signal transmission line 6 passing through the hinge device 7 is enclosed within a structural member consisting of a spring plate 71 and a wire shield 72. The wire shield 72 is fixedly connected to the inner side of the spring plate 71, and the wire shield 72 and the spring plate 71 surround each other to form a receiving space 721 through which the signal transmission line 6 passes. In another possible implementation, the wire shield 72 may also be fixedly connected to the outer side of the spring plate 71.

[0200] In the smart glasses 1 provided in this application embodiment, a receiving space 721 for the signal transmission line 6 to pass through is formed by the spring piece 71 and the wire shield 72. The structure is simple, and while ensuring the elastic clamping force, the thickness of the hinge device 7 can be made thinner and the volume smaller. At this time, the spring piece 71 can be understood as an external part, not wrapped by the wire shield 72. The spring piece 71 can be used as part of the external part of the hinge device 7. After being assembled with the wire shield 72, an internal cavity (i.e., the receiving space 721) is left. This cavity is used to accommodate the transmission line segment of the signal transmission line 6 that passes through the hinge device 7.

[0201] In one example, the wire shield 72 is fixedly connected to the inner or outer side of the spring 71. The material of the wire shield 72 can be, for example, polypropylene (PP) or polycarbonate (PC). This facilitates the fixing of the wire shield 72 and the spring 71, for example, by various fixing methods such as glue application (i.e., fixing through adhesive), clips, etc.

[0202] Furthermore, the cross-sectional shapes of the spring 71 and the wire-blocking member 72 are not limited. For example... ​ As shown, in one possible implementation, the cross-sections of the spring piece 71 and the wire-blocking member 72 are U-shaped. In the thickness direction of the hinge device 7, the U-shaped openings in the spring piece 71 and the U-shaped openings in the wire-blocking member 72 face each other. This ensures the reliability of the fixation between the spring piece 71 and the wire-blocking member 72. The cross-section of the spring piece 71 can be understood as a section perpendicular to its length direction, and the cross-section of the wire-blocking member 72 can be understood as a section perpendicular to its length direction.

[0203] In other possible implementations, the cross-section of the spring piece 71 may also be in other shapes, such as L-shaped or I-shaped, and the cross-section of the wire shield 72 may also be in other shapes, such as L-shaped or I-shaped. This application embodiment does not limit this.

[0204] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
